Leishmaniasis is a neglected tropical disease caused by the unicellular protozoan parasite of genus Leishmania. Tryparedoxin (TXN) is a low molecular mass dithiol protein belonging to oxidoreductases super-family; which function in concert with tryparedoxin peroxidase (TXNPx) as a system in protozoan parasites including Leishmania. Leishmanial hydroperoxides detoxification cascade uses trypanothione as electron donor to reduce hydroperoxide inside the macrophages during infection. However, the mechanism by which tryparedoxin can contribute in progression of visceral leishmaniasis (VL) and its impact on host's cellular immune response during infection in Indian VL patient is unknown...

Asbestos exposure is a determinate cause of many diseases, such as mesothelioma, fibrosis, and lung cancer, and poses a major human health hazard. At this time, there are no identified biomarkers to demarcate asbestos exposure before the presentation of disease and symptoms, and there is only limited understanding of the underlying biology that governs asbestos-induced disease. In our study, we used exosomes, 30-140 nm extracellular vesicles, to gain insight into these knowledge gaps. As inhaled asbestos is first encountered by lung epithelial cells and macrophages, we hypothesize that asbestos-exposed cells secrete exosomes with signature proteomic cargo that can alter the gene expression of mesothelial cells, contributing to disease outcomes like mesothelioma...

We were encouraged to investigate the reasons for large amounts of foam observed in bloodlines during hemodialysis (HD). Foam was visible in the venous air trap within the Artis Gambro dialysis device. Estimates of the extent of foam were graded (0-no foam, 10-extensive foam) by two persons that were blind to the type of dialyzer used. Thirty-seven patients were involved in the dialysis procedures. Consecutive dialyses were graded using dialyzers from Fresenius Medical Care (CorDiax dialyzers that were used for high flux HD-FX80 and FX100, and for hemodiafiltration-FX1000)...

Background: This study's objectives were to describe community oncologists' beliefs about and confidence with geriatric care and to determine whether geriatric-relevant information influences cancer treatment decisions. Methods: Community oncologists were recruited to participate in 2 multisite geriatric oncology trials. Participants shared their beliefs about and confidence in caring for older adults. They were also asked to make a first-line chemotherapy recommendation (combination vs single-agent vs no chemotherapy) for a hypothetical vignette of an older patient with advanced pancreatic cancer...

OBJECTIVE: The relationship between sickle cell disease (SCD) and severe pre-eclampsia is poorly established. It is also unknown whether the occurrence of HIV infection among women with SCD modifies their risk level for severe pre-eclampsia. We hypothesized that pregnant women with SCD are at an elevated risk for severe pre-eclampsia as a result of heightened endothelial damage; and the combination of SCD-HIV augments the inflammatory processes of endothelial damage leading to amplified risk for severe pre-eclampsia...

The type 2 inflammatory response is induced by various environmental and infectious stimuli. Although recent studies identified group 2 innate lymphoid cells (ILC2s) as potent sources of type 2 cytokines, the molecular pathways controlling ILC2 responses are incompletely defined. Here we demonstrate that murine ILC2s express the β2 -adrenergic receptor (β2 AR) and colocalize with adrenergic neurons in the intestine. β2 AR deficiency resulted in exaggerated ILC2 responses and type 2 inflammation in intestinal and lung tissues...

Tissue transglutaminase (tTG) is a multifunctional protein with a wide range of enzymatic and non-enzymatic functions. We have recently demonstrated that tTG expression is upregulated in the pressure-overloaded myocardium and exerts fibrogenic actions promoting diastolic dysfunction, while preventing chamber dilation. Our current investigation dissects the in vivo and in vitro roles of the enzymatic effects of tTG on fibrotic remodeling in pressure-overloaded myocardium. Using a mouse model of transverse aortic constriction, we demonstrated perivascular and interstitial tTG activation in the remodeling pressure-overloaded heart...

Impurity fate and purge studies are critical in order to establish an effective impurity control strategy for approval of the commercial filing application of new medicines. Reversed phase liquid chromatography-diode array-mass spectrometry (RPLC-DAD-MS) has traditionally been the preferred tool for impurity fate mapping. However, separation of some reaction mixtures by LC can be very problematic requiring combination LC-UV for area % analysis and a different LC-MS method for peak identification. In addition, some synthetic intermediates might be chemically susceptible to the aqueous conditions used in RPLC separations...
