#1
Ye Liu, D N Wang, W P Chen
Optical Fabry-Perot interferometer sensors based on inner air-cavity is featured with compact size, good robustness and high strain sensitivity, especially when an ultra-thin air-cavity is adopted. The typical shape of Fabry-Perot inner air-cavity with reflection mode of operation is elliptic, with minor axis along with and major axis perpendicular to the fiber length. The first reflection surface is diverging whereas the second one is converging. To increase the visibility of the output interference pattern, the length of major axis should be large for a given cavity length...

Wheat dwarf virus (WDV) adversely affects cereal production in Asia, Europe, and North Africa. In this study, sequences of several WDV isolates from Iran which is located in the Fertile Crescent were analyzed. Analysis revealed a new geographic cluster for WDV-Wheat from Iran. Recombination analysis demonstrated the existence of several breakpoints in different regions of the viral genome. Data analysis demonstrated that WDV-Barley has an older history and lower diversity than WDV-Wheat. Sequence analysis identified a rare occasion of a co-infection of wheat with WDV-Wheat and WDV-Barley...

Semi-invasive or invasive aspergillosis occurring following chemotherapy with sunitinib is a rare condition with unknown incidence and prognosis. Here, we report a case involving a 59-year-old male who had a history of underlying stable aspergilloma and was newly diagnosed with metastatic renal cell carcinoma. Following surgical resection for renal cell carcinoma and adjuvant chemotherapy with sunitinib for 8 months, the patient presented with hemoptysis. Chest computed tomography revealed an increased soft tissue mass and air crescent sign of the underlying aspergilloma, combined with consolidation and bronchial artery hypertrophy around the lesion...

For several decades, glucocorticoids have been used empirically to treat rapid progressive GN. It is commonly assumed that glucocorticoids act primarily by dampening the immune response, but the mechanisms remain incompletely understood. In this study, we inactivated the glucocorticoid receptor (GR) specifically in kidney epithelial cells using Pax8-Cre/GR(fl/fl) mice. Pax8-Cre/GR(fl/fl) mice did not exhibit an overt spontaneous phenotype. In mice treated with nephrotoxic serum to induce crescentic nephritis (rapidly progressive GN), this genetic inactivation of the GR in kidney epithelial cells exerted renal benefits, including inhibition of albuminuria and cellular crescent formation, similar to the renal benefits observed with high-dose prednisolone in control mice...

BACKGROUND: Longer life expectancy is associated with an increasing prevalence of kidney disease. Aging itself may cause renal damage, but the spectrum of kidney disorders that affect elderly patients is diverse. Few studies, mostly form US, Asia and West Europe found differences in the prevalence of some types of kidney diseases between elderly and younger patients based on renal biopsy findings, with varied proportion between glomerulopathies and arterionephrosclerosis as a dominant injury found...

Lupus nephritis is a life-threatening complication of systemic lupus erythematosus (SLE). Various growth factors, cytokines, and chemokines are implicated in the development of SLE. However, the pathophysiological processes involved in the development of lupus nephritis still remain unclear. In this study, we examined the involvement of activin A, a member of TGF-β superfamily, in the progression of renal damage in lupus-prone MRL-lpr mice. Activin A was was not expressed in the kidneys of normal C57BL/6 mice but was detectable in perivascular infiltrating CD68-positive cells in the kidneys of MRL-lpr mice...

Antineutrophil cytoplasmic antibodies (ANCA) are well known to be associated with several types of vasculitis, including pauci-immune crescentic glomerulonephritis, a form of rapid progressive glomerular nephritis (RPGN). ANCA vasculitis has also been reported after administration of propylthiouracil, hydralazine, cocaine (adulterated with levimasole), allopurinol, penicillamine and few other drugs. All previously reported cases of drug-associated ANCA glomerulonephritis were in native kidneys. Sofosbuvir is a new and effective drug for hepatitis C virus infection...

AIM: MMP-12 (macrophage elastase) is an enzyme that can cleave various extracellular matrix proteins and is required for macrophage infiltration and pulmonary fibrosis in experimental emphysema. We have shown previously that MMP-12 is highly up-regulated in experimental anti-glomerular basement membrane (GBM) disease. The aim of this study was to determine whether MMP-12 is required for glomerular macrophage infiltration and crescent formation in anti-GBM glomerulonephritis. METHODS: Accelerated anti-GBM disease was induced in groups of MMP-12 gene deficient mice (MMP-12-/-) and wild type C57BL/6 J (WT) controls, which were killed 12 days after injection of anti-GBM serum...

Macrophages are multifunctional immune cells that may either drive or modulate disease pathogenesis, depending on the activated phenotype. In this study, we investigated the protective effects of CD206(+) M2 macrophages against nephrotoxic serum nephritis in mice. We found that these immunosuppressive macrophages, derived from bone marrow and stimulated with IL-4/IL-13 [CD206(+) M2 bone marrow-derived macrophages (M2BMMs)], protected against renal injury, decreased proteinuria, and diminished the infiltration of CD68(+) macrophages, neutrophils, and T cells into glomerular tissue...

: SAR11 bacteria are small, heterotrophic, marine α-proteobacteria found throughout the oceans. They thrive at the low nutrient concentrations typical of open ocean conditions, although the adaptations required for life under these conditions are not well understood. To illuminate this issue we used cryo-electron tomography to study Pelagibacter, strain HTCC1062, a member of SAR11 clade. Our results revealed its cellular dimensions and details of its intracellular organization. The frozen-hydrated cells, which are preserved in a life-like state, have an average cell volume (enclosed by outer membrane) of 0...

Supported by a kinetic simulation, we derive an exclusion energy parameter E_{X} providing a lower kinetic energy bound for an electron to cross from one inflow region to the other during magnetic reconnection. As by a Maxwell demon, only high-energy electrons are permitted to cross the inner reconnection region, setting the electron distribution function observed along the low-density side separatrix during asymmetric reconnection. The analytic model accounts for the two distinct flavors of crescent-shaped electron distributions observed by spacecraft in a thin boundary layer along the low-density separatrix...

The contemporary context of population aging, itsthe population's different health and disease characteristics, and the growing incorporation of technologies by healthcare systems have highlighted the need to adjust the healthcare structure as a whole. The defense of a democratic and sustainable system reveals the importance of understanding how changes in healthcare take place. The current article aims to contribute to the understanding of innovation in healthcare services. The study's results indicate that the existence of certain knowledge gaps means that public policies tend to overlook a whole rangeseries of innovations normally associated with social changes, with a consequentwith an impact on human development, social cohesion, equality, and equity, allcentral issues that are central toin the field of collective public healthcare field...
