Electron microscopy is the gold standard to characterize cellular ultrastructure. However, production of significant morphometrical data is highly limited by acquisition time. Here, we describe a semi-automated high-throughput strategy using single-axis serial section electron tomography to investigate and analyze centriole ultrastructure in bone-marrow-derived, primary human CD138 plasma cells. The protocol comprises steps for electron microscopy sample preparation, semi-automated transmission electron microscopy screening, and screening evaluation for cells of interest. Thereafter, we detail tomography acquisition, data reconstruction, and joining. For complete details on the use and execution of this protocol, please refer to Dittrich et al..

Immunoglobulin A nephropathy (IgAN) is the most common primary glomerulonephritis worldwide with heterogeneous histopathological phenotypes. Although IgAN with membranoproliferative glomerulonephritis (MPGN)-like features has been reported in children and adults, treatment strategies for this rare IgAN subtype have not been established. Here, we present the case of a 56-year-old man with no history of kidney disease who initially presented with nephrotic syndrome.

In this study, polyethylene glycol (PEG) and dextran (Dex) were chemically modified to obtain amino-functionalized PEG (PEG-(NH)) and oxidized dextran (ODex). They were subsequently reacted via -NH and -CHO groups to synthesize a macromolecular Schiff base particle. The structures, morphologies, and thermal properties of the macromolecular Schiff base particle were characterized using Fourier-transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), and thermogravimetry analysis (TGA).

Resolvin D1 (RvD1) is an endogenous anti-inflammatory mediator that modulates the inflammatory response and promotes inflammation resolution. RvD1 has demonstrated neuroprotective effects in various central nervous system contexts; however, its role in the pathophysiological processes of intracerebral hemorrhage (ICH) and the potential protective mechanisms when combined with exercise rehabilitation remain unclear. A mouse model of ICH was established using collagenase, and treatment with RvD1 combined with three weeks of exercise rehabilitation significantly improved neurological deficits, muscle strength, learning, and memory in ICH mice while reducing anxiety-like behavior.

The increasing concern over microbial resistance to conventional antimicrobial agents used in food preservation has led to growing interest in plant-derived antimicrobial peptides (AMPs) as alternative solutions. In this study, the antimicrobial mechanisms of chia seed-derived peptides YACLKVK, KLKKNL, KLLKKYL, and KKLLKI were investigated against Staphylococcus aureus (SA) and Escherichia coli (EC). Fluorometric assays and scanning electron microscopy (SEM) demonstrated that the peptides disrupt bacterial membranes, with propidium iodide (PI) uptake reaching 72.

Very high heat is generated during the polymerization of poly (methyl methacrylate) (PMMA) bone cement, which is used for implant fixation in orthopedic surgery. As such, it has been suggested that irrigating the bone cement layer in the surgical site with a saline solution is a way of cooling the layer. In this study, we aimed to determine the influence of irrigation with a saline solution on the flexural strength and the microstructure of the test specimens of two PMMA bone cement brands: Simplex P and FIX 1.
