The presence of human immunodeficiency virus (HIV)-related kidney disease is an important cause of mortality and morbidity. HIV infection induces renal injury by direct cytotoxicity or immune complex-mediated glomerulonephritis in patients with genetic susceptibility factors. In the last decades, with the development and diffusion of combination antiretroviral therapy, which has prolonged patient survival, there has been a shift in the spectrum of renal diseases in HIV-infected patients, with the decrease of glomerular diseases and increase in the role of nephrotoxicity and co-morbidities. This review provides a contemporary and critical review on the main renal syndromes occurring in HIV-infected patients.

Significant Mortality

As viruses, microbes, other pathogenic microorganisms and toxic agents are responsible for global broad spectrum diseases including cancer and malignant hypercalcemia, resulting significant mortality and morbidity, nanobiotechnology-based nanoparticles are being emerged as new nanomedicines for their biological applications owing to their unique shape, size and ease surface functionalizations. To overcome drug resistance and toxicity, gallium (Ga(III)) metal nanoparticles (GaNPs) have attracted attention for their requirements for prolonged treatments, especially, against human immunodeficiency virus, mycobacterium, hypercalcemia and cancer. These nanoparticles remain stable for the longer periods owing to the formation of native and passivating 2-3 nm oxide layer. Therefore, it is needed to encapsulate the NPs with bioactive compounds within vesicular system associated ligand-binding for specific delivery to target-sites for getting better efficacies. This review depicts especially the role of GaNPs as delivery system against infectious diseases and cancer.

Podocyte Detachment

In the past two decades, intravital imaging using multiphoton microscopy has provided numerous new visual and mechanistic insights into glomerular biology and disease processes including the function of glomerular endothelial cells (GEnC), podocytes, and the development of proteinuria. Although glomerular endothelial injury is known to precede podocyte damage in several renal diseases, the primary role of GEnCs in proteinuria development received much less attention compared to the vast field of podocyte pathobiology. Consequently, our knowledge of GEnC mechanisms in glomerular diseases is still emerging. This review highlights new visual clues on molecular and cellular mechanisms of GEnCs and their crosstalk with podocytes and immune cells that were acquired recently by the application of multiphoton imaging of the intact glomerular microenvironment in various proteinuric disease models. New mechanisms of glomerular tissue remodeling and regeneration are discussed based on results of tracking the fate and function of individual GEnCs using serial intravital multiphoton imaging over several days and weeks. The three main topics of this review include (i) the role of endothelial injury and microthrombi in podocyte detachment and albumin leakage via hemodynamic and mechanical forces, (ii) the alterations of the endothelial surface layer (glycocalyx) and its interactions with circulating immune cells in lupus nephritis, and (iii) the structural and functional remodeling and regeneration of GEnCs in hypertension, diabetes, and other experimental injury conditions. By the comprehensive visual portrayal of GEnCs and the many other contributing glomerular cell types, this review emphasizes the complexity of pathogenic mechanisms that result in proteinuria development.

Abstract Extracellular vesicles (EVs) are membrane-bound vesicles released by most cells and are found in diverse biological fluids. The release of EVs provides a new mechanism for intercellular communication, allowing cells to transfer their functional cargoes to target cells. Glomerular diseases account for a large proportion of end-stage renal disease (ESRD) worldwide. In recent years, an increasing number of research groups have focused their effort on identifying the functional role of EVs in renal diseases. However, the involvement of EVs in the pathophysiology of glomerular diseases has not been comprehensively described and discussed. In this review, we first briefly introduce the characteristics of EVs. Then, we describe the involvement of EVs in the mechanisms underlying glomerular diseases, including immunological and fibrotic processes. We also discuss what functions EVs derived from different kidney cells have in glomerular diseases and how EVs exert their effects through different signaling pathways. Furthermore, we summarize recent advances in the knowledge of EV involvement in the pathogenesis of various glomerular diseases. Finally, we propose future research directions for identifying better management strategies for glomerular diseases.

Biopsy Interpretation

Diverse pathogenetic mechanisms and clinical manifestation of renal diseases may produce the same renal morphologic pattern or variety of renal morphologic pattern can lead to the same clinical syndrome. The primary role of the renal biopsy is to provide a diagnosis and information about disease activity and chronicity. The systematic approach to native medical renal biopsy includes evaluation of the four compartments of the kidney sequentially (glomeruli, tubules, interstitium, and blood vessels). The diagnosis in renal pathology is an integrated process in which we must analyze all clinical data, light microscopy, immunohistology, and electron microscopy studies for diagnosis. The aim of the article is to describe the handling of the renal tissue in the anatomical pathology laboratory. It also provides the guideline to renal biopsy evaluation and approach to arrive at the diagnosis of glomerular diseases with similar clinical presentations.

The wear resistance and wear characteristics of cluster-gradient architecture (CGA) nanostructured topocomposites are studied. The specifics of tribocontact interaction under microcutting conditions is considered. The reasons for retention of high wear resistance of this class of nanostructured topocomposites are studied. The mechanisms of energy dissipation from the tribocontact zone, due to the nanogeometry and the structural-phase structure of CGA topocomposites are analyzed. The role of triboactivated deformation and diffusion processes in providing increased wear resistance of carbide-based topocomposites is shown. They are tested under the conditions of blade processing of heat-resistant titanium alloy.
