This study was conducted to select electrogenic bacteria from wastewater sludge. Phylogenetic analysis revealed that Proteobacteria was the dominant phylum in the microbial fuel cell (MFC) during the decomposition process of organic pollutants. Five culturable bacteria strains - namely, Bacillus subtilis, Flavobacterium sp., Aeromonas hydrophila, Citrobacter freundii, and Stenotrophomonas sp. - have a double potential in dye removal and electricity generation. We inoculated the mixed electrogenic bacteria at a specific ratio and treated them with a triphenylmethane dye, Victoria blue R (VBR), to evaluate their electricity generation ability for the artificial and real wastewater...

Visible-light-driven water splitting was investigated in a dye sensitized photoelectrosynthesis cell (DSPEC) based on a photoanode with a phosphonic acid-derivatized donor--acceptor (D--A) organic chromophore, 1, and the water oxidation catalyst [Ru(bda)(4-O(CH2)3P(O3H2)2-pyr)2], 2, (pyr = pyridine; bda = 2,2'-bipyridine-6,6'-dicarboxylate). The photoanode was prepared by using a layering strategy beginning with the organic dye anchored to an FTO|core/shell electrode, atomic layer deposition (ALD) of a thin layer (< 1 nm) of TiO2, and catalyst binding through phosphonate linkage to the TiO2 layer...

A deep-blue emitter was developed by modifying carbazole nuclear positions C2 & C7 with a triphenylamine donor and C3 & C6 with a cyano acceptor. The molecular design features cross-conjugated localized and charge transfer chromophores which results in a hybridized local charge transfer (HLCT) excited state. An organic light emitting diode (OLED) using this material exhibited high external quantum efficiency (6.5%) with excellent color saturation (CIEy ∼ 0.06) and small full-width at half maximum (48 nm).

REVIEW
Alessandro Vitale, Quirino Lai
Although liver transplantation (LT) represents the gold-standard strategy for hepatocellular cancer (HCC), its use is circumscribed by several factors like donor shortage, perioperative complications, or competition with other candidates without HCC. Moreover, different alternative approaches like resection or loco-regional therapies may be attempted in selected cases. The best option for the treatment of an HCC patient is a complex decision, involving several ethical principles including: equity (horizontal equity and vertical equity or urgency), and utility...

The development of tissue fibrosis in the context of a wound-healing response to injury is common to many chronic diseases. Unregulated or persistent fibrogenesis may lead to structural and functional changes in organs that increase the risk of significant morbidity and mortality. We will explore the natural history, epidemiology, and pathogenesis of fibrotic disease affecting the lungs, kidneys, and liver as dysfunction of these organs is responsible for a substantial proportion of global mortality. For many patients with end-stage disease, organ transplantation is the only effective therapy to prolong life...

Non-directed living donors (NDLD) are an important and growing source of kidneys to help reduce the organ shortage. In its infancy, NDLD transplantation was clustered at a few transplant centers and rarely benefited African American recipients. However, NDLDs have increased 9.4-fold since 2000, and now are often used to initiate kidney paired donation (KPD) chains. Therefore, we hypothesized that the initial geographic clustering and racial disparities may have improved. We used SRTR data to compare NDLDs and their recipients between 2008-2015 and 2000-2007...

BACKGROUND: It's unclear whether pre-transplant T. gondii seropositivity is associated with impaired survival in heart transplant recipients. OBJECTIVES: To test the above-mentioned hypothesis in the Spanish Heart Transplantation Registry. METHODS: Post-transplant outcomes of 4048 patients aged >16years who underwent first, single-organ heart transplantation in 17 Spanish institutions from 1984 to 2014 were studied. Long-term post-transplant survival and survival free of cardiac death or retransplantation of 2434 (60%) T...

Neutral lipids packed in lipid droplets (LDs) are essential as a source of fuel for organisms, and specialized storing cells, the adipocytes, provide a buffer for energy variations. Many modern-society-disorders are connected with excess accumulation or deficiency of LDs in adipose tissue. Intracellular LD number and size distribution reflect the tissue conditions, while the associated mechanisms and genes rs are still poorly understood. Large-scale genetic screens using human in vitro differentiated primary adipocytes require cell samples donated from many patients...

The reactivity of carbon dioxide with vanadium(III) aryloxo complexes has been investigated. The formation of either carbon monoxide or incorporation into the ligand system with the ultimate formation of organic ester was observed depending on the overall electron donor ability of the ligand field. DFT calculations were carried out to investigate the proposed mechanism for carbon dioxide coordination and reduction.

Sulfolobus islandicus is rapidly emerging as a model system for studying the biology and evolution within the TACK lineage of the Archaeal domain. As the tree of life grows, identifying the cellular function of genes within this lineage will have significant impacts on our understanding of the evolution of Last Archaeal Eukaryote Common Ancestor (LEACA) and the differentiation of Archaea from Eukaryotes during the evolution of the modernday cell. To progress our understanding of this key Archaeal organism, we report a novel high-throughput method for targeted gene inactivation in S...

Broad host range conjugative plasmids that replicate in Escherichia coli have been widely used to mobilise smaller replicons, bearing their cognate origin of transfer (oriT) into a variety of organisms that are less tractable genetically, such as Clostridium (Clostridioides) difficile. In this work we demonstrated that the oriT region of pMTL9301 (derived from RK2) is not required for transfer between E. coli and C. difficile strains 630Δerm and CD37 and that this oriT-independent transfer is abolished in the presence of DNase when CD37 is the recipient...

South Africa has a rich organ-transplant history, and studies suggest that the SA public supports organ donation. In spite of this, persistently low donor numbers are a significant challenge. This may be due to a lack of contextually appropriate awareness and education, or to barriers to referring patients and families in clinical settings. It may also be due to ad hoc regulations that are not uniformly endorsed or implemented. In this article we present the findings of a study in Johannesburg that explored the attitudes and roles of nurses in end-of-life care and organ donation...

With the recent introduction of more potent modern immunosuppressive regimens in solid-organ transplant, new types of viral infections such as adenovirus are emerging as a potential cause for graft dysfunction and loss. We report a case of 41-year-old male patient with end-stage renal disease from recurrent kidney stones who underwent kidney transplant from a deceased 12-year-old female donor. He developed adenoviral infection with acute cystitis, microscopic hematuria, and necrotizing interstitial nephritis associated with graft dysfunction within the first month of the postoperative period...

Biological removal of nitrate, a highly-concerning contaminant, is limited when the aqueous environment lacks bioavailable electron donors. In this study, we demonstrated, for the first time, that bacteria can directly use the electrons originated from photoelectrochemical process to carry out the denitrification. In such photoelectrotrophic denitrification (PEDeN) systems (denitrification biocathode coupling with TiO2 photoanode), nitrogen removal was verified solely relying on the illumination dosing without consuming additional chemical reductant or electric power...

Therapeutic options for extrahepatic metastases following Liver Transplantation(LT) for Hepatocellular carcinoma(HCC) are limited, and the prognosis remains poor. Innovative blockade of immune checkpoints, such as monoclonal antibodies against programmed death receptor 1 have shown promise in the treatment of solid organ malignancies. Here, we report a case of metastatic HCC after LT, where Pembrolizumab was started following a poor response with Sorafenib. There was a complete radiological response to the drug with no liver graft rejection or dysfunction...

The use of hepatitis C virus (HCV) positive organs in liver transplantation has increased in the era of direct-acting antiviral therapy. A rising demand for organs, the ability to effectively treat HCV infection in the transplant setting, and an unprecedented increase in HCV positive donors have all contributed to this trend. A recent abrupt rise in opioid use in the US has resulted in a surge of injection drug use, transmission of HCV, and opioid-related overdose deaths. Geographic areas most affected by the opioid epidemic have experienced a rapid increase in recovery and utilization of HCV positive donor organs, in which the proportion of deceased donor liver transplants in the US from donors who are HCV positive has increased nearly two-fold within the last three years...

The all-female Amazon molly (Poecilia formosa) is the result of a hybridization of the Atlantic molly (P. mexicana) and the sailfin molly (P. latipinna) approximately 120,000 years ago. As a gynogenetic species, P. formosa needs to copulate with heterospecific males including males from one of its bisexual ancestral species. However, the sperm only triggers embryogenesis of the diploid eggs. The genetic information of the sperm donor typically will not contribute to the next generation of P. formosa. Hence, P...
