Cellular and compositional insight into the sludge dewatering process using enzyme treatment
Abstract
Removal of intracellular water in microbial cells remains a key issue for sludge disposal, and here, a novel method of enzymatic treatment with two enzymes, lysozyme and protease, was employed. Total internal reflection fluorescence microscope (TIRF) was applied to image the bacteria in sludge and quantify the evolution of sludge bacteria for the first time. The ratio of dead/live bacterial cells was always higher in the presence of lysozyme than in the presence of protease, indicating that lysozyme has higher activity in inducing bacterial cell degradation and releasing intracellular water. The compositions of extracellular polymeric substances (EPS) were further measured, and the results show that the dewatering performance of sludge is correlated both to the release of cell contents and the variations in EPS composition during cell degradation. Moreover, kinetic analysis demonstrated that the enzyme-catalyzed reaction was substantially completed within 1 h, i.e., the reaction was quite rapid during the first 1 h, and thereafter, it gradually reduced to stability. The mechanism of enzymatic treatment of sludge explored in this study thus not only enhanced the understanding of sludge deep dewatering but also provided significant methodological clues for the disposal of sludge.

Das hepatozelluläre Karzinom – pathologische und molekularpathologische Diagnostik
Zusammenfassung
Hintergrund
Das hepatozelluläre Karzinom (HCC) ist histopathologisch definiert. Histo- und molekularpathologische Diagnostikverfahren sind Grundlage einer stadiengerechten Therapie, aber auch therapeutischer Innovation. Basierend auf klassischen histologischen Charakteristika wurden in den letzten Jahren vielfältige Verbesserungen hin zu einer modernen, morphomolekularen Diagnostik des HCC erreicht: multiple neue Marker zur Präzisierung der Differenzial- und insbesondere Malignitätsdiagnose bei hochdifferenzierten Lebertumoren; Definition neuer tumorbiologisch definierter und relevanter HCC-Subtypen, die bis zu 30 % der HCC betreffen; molekulare Zielstrukturen und potenzielle prädiktive Marker für präzisionsonkologische Ansätze. Dies sind Bausteine einer neuen morphomolekularen Klassifikation des HCC, die eine wesentliche zukünftige Herausforderung darstellt.
Künftige Anforderungen
Es muss nicht nur eine neue morphomolekulare Klassifikation erstellt werden, sondern auch die Position der Biopsiediagnostik des HCC bedarf einer grundlegenden Verbesserung. Zudem müssen neue immunonkologische Ansätze diagnostisch sinnvoll untermauert werden und die neuen Erkenntnisse in entsprechend geplanten Studien und auch geeigneten zentrenbasierten Ansätzen diagnostisch und klinisch umgesetzt werden, um die in Bezug auf andere relevante Tumorarten immer noch unbefriedigende klinische Position des HCC nachhaltig zu verbessern.

Abstract
Liposomes are a common delivery vehicle for drugs or biologicals, but some common surfactants used as liposome components may cause denaturation and malfunction of serum proteins and cell surface proteins. In this study, we examined the effects of liposome lipid didodecyldimethylammonium bromide (DDAB), nonionic polyoxyethylene sorbitan monooleate 80 (Tween 80), and the equimolar mixture on the properties of serum proteins. Bovine serum albumin was selected as the main model protein, and the effects of the DDAB, Tween 80, and a 1:1 mixture on its spectroscopic behavior were investigated. The effects of surfactants on the five major serum proteins: human serum albumin, apolipoprotein A1, transferrin, fibrinogen and immunoglobulin G were also examined. Finally, the results were verified on human serum. The results indicated that weak interactions exist between human serum proteins and the equimolar mixture of DDAB–Tween 80, significantly different from the strong interactions of DDAB and Tween 80 with proteins. The salient features of cationic–nonionic surfactants enable their use in liposome composition, with improved drug delivery efficiency.

Abstract
The multipurpose plant species Linum usitatissimum famous for producing linen fibre and containing valuable pharmacologically active polyphenols, has rarely been tested for it's in vitro biosynthesis potential of lignans and neolignans. The current study aims at the synergistic effects of mineral nutrients variation and different photoperiod treatments on growth kinetics and biomass accumulation in in vitro cultures of Linum usitatissimum. Both nutrient quality and quantity affected growth patterns, as cultures established on Gamborg B5 medium had comparatively long exponential phase compared to Murashige and Skoog medium, while growth was slow but steady until last phases of the culture on Schenk and Hildebrandt medium. Similarly, we observed that boron deficiency and nitrogen limitation in culture medium (Gamborg B5 medium) enhanced callus biomass (fresh weight 413 g/l and dry weight 20.7 g/l), phenolics production (667.60 mg/l), and lignan content (secoisolariciresinol diglucoside 6.33 and lariciresinol diglucoside 5.22 mg/g dry weight respectively) at 16/8 h light and dark-week 4, while that of neolignans (dehydrodiconiferyl alcohol glucoside 44.42 and guaiacylglycerol-β-coniferyl alcohol ether glucoside 9.26 mg/g dry weight, respectively) in continuous dark after 4th –week of culture. Conversely, maximum flavonoid production occurred at both Murashige and Skoog, Schenk and Hildebrandt media (both media types contain comparatively higher boron and nitrogen content) in the presence of continuous light. Generally, continuous dark had no significant role in any growth associated parameter. This study opens new dimension for optimizing growing conditions and evaluating underlying mechanisms in biosynthesis of lignans and neolignans in in vitro cultures of Linum usitatissimum.
The impact of wetland on neutral mine drainage from mining wastes at Luanshya in the Zambian Copperbelt in the framework of climate change
Abstract
The impact of a natural wetland ("dambo" in Zambia) on neutral mine drainage at Luanshya in the Zambian Copperbelt has been investigated during an intermediate discharge period (July) using a multi-method characterization of solid phase samples, sequential extraction analysis, X-ray diffraction, Mössbauer spectroscopy, and scanning electron microscopy combined with water analyses, isotopic analyses, and geochemical modeling. In the wetland, the principal identified solid phases in sediments were carbonates, gypsum, and ferric oxyhydroxides. A significant portion of the ochres was present as insoluble hematite. Mine drainage pH values decrease, and log \( {P}__2} \) values increase after inflow of water into the wetland; dissolved and suspended concentrations of Fe, Mn, Cu, and Co also decrease. Based on speciation calculations, there is no precipitation of secondary Cu and Co minerals in the period of sampling, but it can occur later in dry period when the flow rate is reduced. Concentrations of sulfate decrease, and values of δ34S(SO4) in the wetland increase in parallel, suggesting sulfate reduction is occurring. In more advanced dry period, the discharge in mine drainage stream is probably much lower and water can reach supersaturation with respect to minerals such as gypsum, which has been found in sediments. Wetlands have a positive impact on mine drainage water quality due to the removal of metals by adsorption, co-precipitation, and filtration of colloids. However, there can also be a rebound of contamination by seepage inflow downstream from the wetland. Ongoing climate change with extreme hydrologic events may enhance differences between dry and rainy seasons with resulting faster mobilization of contaminants.
Statistical physics modeling of synthetic dyes adsorption onto Spirulina platensis nanoparticles
Abstract
Experimental adsorption of synthetic dyes, FD&C red no. 40 and Tartrazine, onto Spirulina platensis has been analyzed using a statistical physics treatment at different temperatures (298, 308, 318, and 328 K) and at different values of pH (4, 6, and 8). The statistical physics formalism was used to develop the analytical expressions of models. The interpretation of the adsorption of these dyes on Spirulina platensis was achieved by choosing the adequate model and by presenting the evolution of the parameters involved in the analytical expression of this model such as the number of adsorbed dye molecules per site (nd), the receptor sites density (Dr), the adsorbed quantity at saturation (qs), and the molar adsorption energy (ΔE). Thus, several interpretations and results describing the adsorption of dyes on Spirulina platensis are extracted regarding the behaviors of these parameters at different temperatures and different values of pH. Thermodynamic functions such as the Gibbs free energy, the internal energy, and the entropy are studied at different values of pH.
Leachable lead and cadmium in microwave-heated ceramic cups: possible health hazard to human
Abstract
In this study, we assessed the leachability as well as health risk associated with the consumption from glazed, colourful, ceramic cups, containing lead and cadmium. Both metals leached into the 2.5-min microwave-heated (convection mode, at 140 °C) double-distilled water in concentrations above 0.5 mg/L, the permissible limits of leachable Pb and Cd in ceramic mugs set by United States Food and Drug Administration (US FDA). On an average, significantly higher Pb leached in new cups, 7.69 ± 0.56 mg/L, compared to that in old cups, 3.15 ± 0.15 mg/L. Cd leached similarly in both old (1.97 ± 0.14 mg/L) and new cups (1.57 ± 0.005 mg/L). The chronic daily intake of Pb by children and adults, respectively, consuming from new cups were 1.3–5× and 1.28–6× more than that from old cups. In both the cases, intake values far exceeded WHO reference dose of 0.0006 mg Pb/kg bw/day in children (< 11 years) and 0.0013 mg Pb/kg bw/day in adults. Such levels of Pb consumption in children might be predicted to be associated with decrement in IQ by at least 1 point and adverse effects in adults, especially, women of childbearing age. The daily intake of Cd from these cups ranged from 0.002–0.049 mg/kg bw/day, which was also above permissible limit. Consequently, high hazard quotient and hazard index (both more than 1) were observed for these metals, which might impart individual as well as cumulative effects on the health. Thus, apart from other dietary as well as inhalation sources of contaminants (which were not studied here), regular consumption of beverages alone in glazed, ceramic cups increased chances of Pb- and Cd-related health risks to humans.

Comparative study of the direct black removal by Fe, Cu, and Fe/Cu nanoparticles
Abstract
In this study, direct black dye removal was investigated using iron nanoparticles (Fe NPs), copper (Cu NPs), and Fe/Cu (Fe/Cu NPs). NPs were characterized by transmission electron microscopy (TEM) and X-ray diffraction (XRD). Using a dose of 0.25 g L−1 of Fe, Cu, and Fe/Cu NPs, a degradation efficiency of 13, 26, and 43% respectively was obtained. For the 1.00 g L−1 dose, the efficiency increased to 100, 43, and 100%, respectively. Studies in anoxic and oxic conditions presented degradation rates, respectively, of 100 and 30% for Fe NPs, 90 and 50% for Fe/Cu NPs, and 40% in both reactions for Cu NPs, indicating that the mechanism of dye degradation by NPs is predominantly reducing under the conditions studied. The addition of EDTA decreased the dye removal rate for Fe, Cu, and Fe/Cu NPs at 27, 10, and 35%, respectively. In addition to the degradation, the adsorption phenomena of the by-products formed during the reaction were confirmed by the Fourier transform infrared (FTIR) analysis and verified by the desorption tests. Fe and Fe/Cu NPs showed the highest efficiency in direct black dye reductive degradation and adsorption of by-products, removing 100% of the dye at a dose of 1 g L−1 within 10 min of reaction.

Management of Lumbar Spondylolysis in Athletes: Role of Imaging
Abstract
Purpose of review
Spondylolysis is a broad term, with advances in imaging enabling more accurate diagnosis of the activity and severity of a lesion. This review discusses the role of different imaging modalities in the diagnosis and management of lumbar spondylolysis in athletes.
Recent Findings
Magnetic resonance imaging (MRI) has diagnostic and practical advantages over other imaging modalities and is particularly useful for detecting early stages of bone stress, including pre-symptomatic screening for active lumbar bone stress injuries. Whilst computed tomography remains the best imaging technique to visualise cortical breaches, specialised MRI sequences offer a viable alternative to detect active bone stress and chronic non-united defects.
Summary
Imaging provides important information for the clinical management of athletes with lumbar spondylolysis. Roles for imaging, in particular MRI, include: (a) proactive screening and early detection, (b) diagnosis of a symptomatic lesion and (c) monitor healing and readiness to return to sport.
Fate of febantel in the aquatic environment—the role of abiotic elimination processes
Abstract
Febantel is widely used anthelmintic drug active against a range of gastrointestinal parasites in animals. Despite the fact that it has been detected in the aquatic environment, there is no information on its environmental fate. Therefore, abiotic elimination processes of febantel in the aquatic environment have been studied. The results of direct and indirect photodegradation experiments showed that febantel was persistent against solar radiation. Kinetics of hydrolytic elimination was pH and temperature dependent with half-lives in the range from 210 min to 99 days. Febantel metabolites, fenbendazole and fenbendazole sulfone, were found as major degradation products using high-resolution mass spectrometry. The proposed hydrolytic degradation pathway consisted of the base catalyzed hydrolysis followed by consecutive oxidative cyclization to the five-membered ring of the benzo-imidazole derivative. Aquatic toxicity of febantel and its hydrolytic mixture were evaluated toward the luminescence bacteria Vibrio fischeri. Investigation of febantel sorption onto river sediments showed that the best agreement was obtained with the linear model (R2 > 0.99), while the rate of sorption is the best described with the kinetic model of pseudo-second order. The organic carbon-normalized sorption coefficient, KOC, ranged from 1490 to 3894 L kg−1 for five sediment samples. The results of this research demonstrate that febantel persist in the natural waters and potentially could travel far from the source.
Nail apparatus melanoma: Experience of 10 years in a single institution
Background: Nail apparatus melanoma (NAM) is rare. The higher mortality reported in the literature, compared with melanoma on other sites is probably due to advanced disease associated with a delay in diagnosis and treatment.
Comparison of noninsulated microneedle and noninvasive fractional radiofrequency devices in an animal model of skin rejuvenation
Background: Radiofrequency (RF) devices based on various delivery systems are clinically effective in treating many dermatologic conditions. However, there are few histologic studies identifying the therapeutic mechanism and its effect.
Sodium thiosulfate injection dissolves calcium hydroxylapatite particles: An animal study
Background and objective: Treatment of certain dermal filler–related serious AEs (e.g., vascular occlusion, granulomatous reactions) may include removal of the injected material. Hyaluronidase can be used to degrade hyaluronic acid fillers; however, no agents have yet been shown to fully dissolve calcium hydroxylapatite (CaHA; Merz North America) filler after placement. Sodium thiosulfate (STS) has been shown to decrease calcium mineral deposits associated with calciphylaxis, calcific uremic arteriolopathy, and kidney stones.
Topical oxymetazoline hydrochloride 1.0% effectively reduces persistent facial erythema of rosacea on day 1
Introduction: Persistent facial erythema is a bothersome, therapeutically challenging feature of rosacea; therapies with clear efficacy at treatment onset are needed. In 2 identically designed, phase 3 pivotal, randomized, multicenter, double-blind, parallel-group, vehicle-controlled, 29-day REVEAL trials, topical oxymetazoline cream 1.0% significantly reduced moderate to severe persistent facial erythema of rosacea. A post hoc analysis of pooled data from both trials assessed erythema reduction on day 1.
Widespread skin necrosis secondary to gemcitabine
Cutaneous side-effects are relatively common in chemotherapy but vary in frequency and severity depending on the medication, dose, duration, pharmacokinetics, and pharmacodynamics. Gemcitabine, a pyrimidine nucleoside analogue, is an oncologic agent used in the treatment of cutaneous T-cell lymphoma (CTCL). Common dermatologic reactions associated with gemcitabine include alopecia, mild skin rash, and mucositis. Rare reports of other cutaneous reactions include lower extremity skin necrosis, lower extremity pseudocellulitis, and scleroderma-like changes.
The antiinflammatory properties of ivermectin and brimonidine in the treatment of papulopustular rosacea
Introduction: The pathophysiology of papulopustular rosacea (PPR) is not fully understood; however, there is increasing evidence that immune and inflammatory responses play an important role in the persistent and perilesional erythema of PPR. Multiple trials have demonstrated the efficacy of ivermectin 1% cream (IVM) and brimonidine 0.33% gel (BR) for treatment of the inflammatory lesions and erythema of PPR, respectively. Two recent studies suggest a promising synergy between IVM and BR in PPR.
Role of activated oligoadenylatesynthetase–ribonuclease L pathways as a novel therapeutic target in psoriasis
Psoriasis (Pso) is predominantly an immune-mediated disease characterized by aberrant epidermal differentiation, surface scale formation, and marked cutaneous inflammation. Immune pathways activated in Pso include amplification of background immune circuits or induction of certain proinflammatory signaling pathways, otherwise latent in normal human skin. These changes include selective induction of antiviral innate immune response genes, differential expression of pathogen associated molecular pattern (PAMP) receptors, cell signaling and cell growth control pathways.
Unveiling the hidden: The eclipsed effect of nondermatophyte infection and mixed-infection onychomycosis
Background: Mixed onychomycosis infections with dermatophytes (DMPs) and nondermatophytes (NDMs) have become more common. While the diagnosis of DMPs onychomycosis is based on mycologic laboratory, that of the NDMs onychomycosis still has several other criteria. Moreover, there had been a few studies about the relationship between fungal feet and nail infection.
Successful vismodegib debulking of a giant basal cell carcinoma of the umbilicus
Introduction: Basal cell carcinoma (BCC) of the umbilicus is an exceptional subtype of BCC with potential slowly progressing deeply invasive and wide growth pattern. Vismodegib is a hedgehog pathway inhibitor indicated for the treatment of large, nonoperable or metastatic BCC.
Secukinumab shows sustained efficacy in difficult-to-treat palmoplantar, nail, and scalp psoriasis: Long-term results from three phase III placebo-controlled randomized trials
Introduction: Psoriasis is a chronic, autoimmune inflammatory condition that can affect different parts of the body including scalp, nails, palms and soles. Psoriasis localized in these areas remains difficult-to-treat, and can result in significant physical and psychosocial disability. Secukinumab, a fully human monoclonal antibody that selectively neutralizes IL-17A, has been shown to have significant efficacy in the treatment of moderate to severe plaque psoriasis and psoriatic arthritis, demonstrating a rapid onset of action and sustained responses up to 5 years with a favorable safety profile.
Venous treatment of lipodermatosclerosis to improve ambulatory function

Treatment patterns among psoriasis patients newly initiated on etanercept or apremilast in a dermatology specialty electronic medical record (EMR) database
Background: Plaque psoriasis (PSO) is a common inflammatory skin disorder that can require chronic treatment. Etanercept (ETN) is a self-injectable biologic indicated to treat moderate-to-severe PSO. Apremilast (APR) is a nonbiologic oral therapy recently approved to treat moderate-to-severe PSO. We sought to examine the real-world treatment patterns of these agents.
The use of silicone gel to enhance skin wound healing by secondary intention following tumor excision on the scalp and extremities: A descriptive study
Secondary intention (SI) healing is advantageous due to shorter surgical time and lower risk of damage to neighboring structures. It is therefore more tolerable in elderly patients with large wounds and is also indicated for lesions at high risk of recurrence as this facilitates closer surveillance. The main disadvantage however is the need for prolonged wound care. Although there is constant effort in adapting materials designed for chronic wounds as an adjunct to SI healing, a recent Cochrane review expounded on the lack of evidence to support any single method.
Systematic review of placebo responses in randomized clinical trials of systemic therapy for atopic dermatitis
Introduction: Atopic dermatitis (AD) is associated with a variable disease severity and symptom burden and intermittent periods of disease remittance, all of which may contribute to increased placebo responses in randomized clinical trials (RCT). However, little is known about the rates and predictors of placebo responses in RCT of systemic therapy in AD.
Stem cell–conditioned media as a potential antiaging technology in skin care
Stem cell conditioned media (SCCM) is gaining increasing interest and is a promising prospect in the field of regenerative medicine. The beneficial effects of stem cell therapy on damaged tissue have shown to be accredited to their ability to secrete trophic factors, rather than their capacity to differentiate into the needed cells. Various studies on stem cell–derived conditioned media from various cell lines, such as adipose-derived stem cells and bone marrow–derived mesenchymal stem cells, have demonstrated tissue repair in various conditions that involved tissue damage.
Silver nanoparticles induce Egr-1–dependent psoriasin expression via the ERK and p38 pathways
Background: Silver nanoparticles (Ag-NPs) have been known to prevent bacterial infection and improve a cutaneous wound healing due to their antimicrobial activity. However, the mechanism of Ag-NPs' antimicrobial activity is poorly understood.
Scabies mimicking pityriasis rosea: Scabies surrepticius
Background: Scabies is a mite infestation caused by Sarcoptes scabiei that is common worldwide. Scabies is diagnosed based on history and exam of the patient, family, and close contacts. Diagnosis is confirmed based on the demonstration of mites, eggs, or mite feces from scrapings of the lesions. The classic presentation of scabies is extreme pruritus and burrows where the mite penetrates the skin and lays eggs. The most common locations of the lesions include the finger webs, flexor surfaces of the wrists, elbows, axillae, buttocks, and genitalia.
Relationship between pruritus and quality of life in patients with atopic dermatitis treated with crisaborole
Introduction: Atopic dermatitis (AD) is a chronic inflammatory skin disease characterized by eczematous lesions and pruritus. Pruritus can lead to exacerbation of disease and reduced quality of life (QoL). Crisaborole ointment is a nonsteroidal phosphodiesterase 4 inhibitor for the treatment of mild to moderate AD. Compared with vehicle, use of crisaborole significantly reduced global disease severity and pruritus in 2 large, identically designed phase 3 clinical studies (AD-301: NCT02118766; AD-302: NCT02118792).
White fibrous papulosus of the neck
Introduction: Whıte fibrous papulosus of the neck (WFPON) is a newly defined clinical diagnosis by Shimizu in 1985. It consists of smooth, linear, 2-3 mm papules, independent of the hair follicles on the neck and back. White fibrous papulosus of the neck (WFPON) and pseudoxanthoma elastic-like dermal elastosis (PXE-PDE) are thought to be clinical variants of the same disease. For this reason, some authors have described WFPON, PXE-PDE and other noninflammatory middermal elastosis cases as "fibroelastolytic variants of primary skin aging." These clinical pictures are clinically similar to each other in many ways, but histologically they can be separated by intact elastic fibers and increased amounts of collagen in the midreticulary dermis.
Using intralesional methotrexate to treat recalcitrant cutaneous Crohn’s disease
Introduction: Cutaneous Crohn's disease (CD) is a rare, and not entirely understood, manifestation of CD that has various clinical presentations. Treatment is difficult, as methods detailed in several case reports over the decades demonstrate mixed efficacy in treating cutaneous CD. Few reports have shown promise using intralesional methotrexate. This case report describes a case of recalcitrant cutaneous CD that resolved with intralesional methotrexate.
Removal of refractory organic pollutants in reverse-osmosis concentrated leachate by Microwave–Fenton process
Abstract
A microwave–Fenton technology was applied to dispose of the reverse-osmosis concentrated leachate. Influential factors on the treatment of concentrated leachate with the pure Fenton and microwave-Fenton method were investigated. For the conventional Fenton process, the removal efficiencies of chemical oxygen demand (CODCr), UV254, and the color number (CN) reached 84%, 87%, and 96%, respectively, with the biodegradability (BOD5/CODCr) increased from 0.13 to 0.51 at an initial pH of 5.0, Fe2+ of 0.04 mol/L, a n(H2O2)/n(Fe2+) ratio of 8 after a reaction time of 3 h. When incorporating the Fenton process with microwave irradiation, a comparative CODCr and UV254, and the CN removal rate of 75%, 83%, and 95%, and a high BOD5/CODCr of 0.62 were achieved under a microwave power of 390 W and an extremely shortened reaction time of only 8 min. Meanwhile, sludge quantity showed a reduction of 24.7%, decreased from 8.50 g/L to 6.40 g/L after the participation of microwave. In addition, molecular-weight fraction (MWF), UV-visible spectrum (UV-vis), and 3D-EEM spectrum tests demonstrated that the macromolecular and complex organic compounds in the wastewater were significantly decomposed into small molecular matters. Our results found that microwave–Fenton is a promising technology for concentrated leachate treatment, with much shorter reaction time, lower sludge production, and enhanced biodegradability, as well as comparative organic matter removal performance.
Strahlentherapie bei hepatozellulärem Karzinom
Zusammenfassung
Hintergrund
Das hepatozelluläre Karzinom (HCC) war für die Strahlentherapie lange keine typische Behandlungsindikation, da es erst in den letzten 2 Dekaden möglich wurde, nichttumoröses Lebergewebe ausreichend zu schonen. Daher ist eine radioonkologische Behandlung auf den einschlägigen Behandlungspfaden noch nicht abgebildet.
Fragestellung
Ziel dieser Arbeit ist es, die Möglichkeiten und Grenzen der Strahlentherapie für Patienten mit HCC darzustellen.
Material und Methode
Nach einer knappen Einführung in die Besonderheiten der Radiotherapie für intrahepatische Tumoren wird für die einzelnen Situationen dargestellt, welche Rolle eine perkutane oder interstitielle Radiotherapie bei der Behandlung des HCC spielen kann. Dazu wird eine Einordnung in den verbreiteten Behandlungsalgorithmus nach der Barcelona Clinic Liver Cancer(BCLC)-Klassifikation verwendet.
Ergebnisse
Die Radiotherapie wird bei HCC derzeit v. a. als Körperstereotaxie (SBRT [„stereotactic body radiotherapy"]) eingesetzt, darüber hinaus seltener auch als interstitielle Brachy- sowie als Protonentherapie. Nach der BCLC-Klassifikation kommt sie am häufigsten im Stadium C, gefolgt vom Stadium B zum Einsatz. Auch bei Patienten, bei denen eine Lebertransplantation angestrebt wird, stellt die Radiotherapie eine Möglichkeit für die Überbrückung der Wartezeit („bridging") dar. HCC-Tumoren sind als eher radiosensibel einzustufen, weshalb oft dauerhafte Lokalkontrollen erreicht werden können. Die wichtigste Nebenwirkung, die es durch korrekte Indikationsstellung und optimale Technik gezielt zu vermeiden gilt, ist eine strahleninduzierte Leberkrankheit. Kombinationen der Radiotherapie mit anderen lokalen Verfahren sind nach vorliegender Datenlage im Allgemeinen gut möglich.
Schlussfolgerungen
Die Radiotherapie ist noch nicht als Standardtherapie der ersten Wahl anzusehen, kann aber als wirksame Methode für die Behandlung des HCC angesehen werden. Erste prospektive Studien rechtfertigen diese Einschätzung.

Absorption, translocation, and detoxification of Cd in two different castor bean ( Ricinus communis L.) cultivars
Abstract
Cadmium (Cd) is considered to be the most phytotoxic heavy metal pollutant. The selection of castor bean cultivars with Cd tolerance and the exploration of the physiological mechanisms involved in Cd tolerance are critical steps for improving phytoremediation performance. In this study, a hydroponic experiment was used to investigate variations in Cd transportation, chelation, and subcellular distribution in two different castor bean cultivars, namely JX-22 and ZB-9. Both cultivars had high tolerance index scores, indicating that both cultivars were tolerant to Cd. The findings of the present study indicate that Cd is significantly more mobile in JX-22 than in ZB-9 during xylem and phloem transportation, resulting in the accumulation of Cd in the shoots of JX-22 was 7.67 times that in ZB-9. Subcellular distribution assessment verified that more Cd was bound to the biologically detoxified metal fractions than the metal sensitive fractions in JX-22. The contents of the non-protein thiol pool and glutathione in the leaves were higher in JX-22 than ZB-9 when exposed to Cd. These results indicate that JX-22 has a greater ability to accumulate Cd, and well-coordinated physiological changes in JX-22 afford greater Cd tolerance in comparison to ZB-9 under Cd exposure, indicating that JX-22 is suitable for use in the remediation of Cd-contaminated soils.
Understanding as compression
Abstract
What is understanding? My goal in this paper is to lay out a new approach to this question and clarify how that approach deals with certain issues. The claim is that understanding is a matter of compressing information about the understood so that it can be mentally useful. On this account, understanding amounts to having a representational kernel and the ability to use it to generate the information one needs regarding the target phenomenon. I argue that this ambitious new account can accommodate much of the data that has motivated theories of understanding in philosophy of science, and can also be generally applicable in epistemology and daily life as well.

Hotspots and main drivers of fecal pollution in Neusiedler See, a large shallow lake in Central Europe
Abstract
To minimize the risk of negative consequences for public health from fecal pollution in lakes, the continuous surveillance of microbiological water quality parameters, alongside other environmental variables, is necessary at defined bathing sites. Such routine surveillance may prove insufficient to elucidate the main drivers of fecal pollution in a complex lake/watershed ecosystem, and it may be that more comprehensive monitoring activities are required. In this study, the aims were to identify the hotspots and main driving factors of fecal pollution in a large shallow Central European lake, the Neusiedler See, and to determine to what degree its current monitoring network can be considered representative spatially. A stochastic and geostatistical analysis of a huge data set of water quality data (~ 164,000 data points, representing a 22-year time-series) of standard fecal indicator bacteria (SFIB), water quality and meteorological variables sampled at 26 sampling sites was conducted. It revealed that the hotspots of fecal pollution are exclusively related to sites with elevated anthropogenic activity. Background pollution from wildlife or diffuse agricultural run-off at more remote sites was comparatively low. The analysis also showed that variability in the incidence of SFIB was driven mainly by meteorological phenomena, above all, temperature, number of sunny hours, and wind (direction and speed). Due to antagonistic effects and temporal undersampling, the influence of precipitation on SFIB variance could not be clearly determined. Geostatistical analysis did reveal that the current spatial sampling density is insufficient to cover SFIB variance over the whole lake, and that the sites are therefore in the most part representative of local phenomena. Suggestions for the future monitoring and managing of fecal pollution are offered. The applied statistical approach may also serve as a model for the study of other such areas, and in general indicate a method for dealing with similarly large and spatiotemporally heterogeneous datasets.
In defense of unfair compromises
Abstract
It seems natural to think that compromises ought to be fair. But it is false. In this paper, I argue that it is never a moral desideratum to reach fair compromises and that we are sometimes even morally obligated to try to establish unfair compromises. The most plausible conception of the fairness of compromises is David Gauthier's principle of minimax relative concession. According to that principle, a compromise is fair when all parties make equal concessions relative to how much they can gain from an agreement and relative to how much they would lose without an agreement. To find out whether reaching a fair compromise sometimes is a moral desideratum, I discuss several paradigmatic cases in friendships, economics and politics, and I try to show that even when the parties have moral reasons to refrain from trying to maximize utility in the negotiations, they do not have moral reasons to aim at a fair compromise. My second claim is that we are sometimes morally obligated to try to establish unfair compromises, in particular when we are dealing with parties that try to establish morally very bad political arrangements. In such cases, we should try to concede as little as possible to achieve an outcome that is morally acceptable. Fair compromises, in other words, are morally much more dubious than is usually appreciated.
