Lupus nephritis with cryoglobulinemic glomerulonephritis features: a diagnostic conundrum
Ultrastruct Pathol. 2023 Oct 18:1-6. doi: 10.1080/01913123.2023.2270030. Online ahead of print.ABSTRACTIn this clinical case, we report an atypical and unique presentation of systemic lupus erythematosus (SLE) in a 39-year-old female with nephrotic syndrome. The patient exhibited class IV plus V lupus nephritis and extensive immune complex deposition within the intracapillary and arteriolar regions suggestive of cryoglobulinemic glomerulonephritis, despite no detectable circulating cryoglobulins. Electron microscopy revealed cryoglobulin-like deposit distribution in all glomerular examined compartments, namely subendotheli...

Adverse neurological effects after exposure to copper, manganese, and mercury mixtures in a Spraque-Dawley rat model: an ultrastructural investigation
In this study, the effects of copper, manganese, and mercury, were evaluated at X100 the World Health Organization safety limits for drinking water. Using a Sprague-Dawley rat model, following exposure for 28 days, the effects of these metals on biochemical blood parameters and tissue and cellular structure of the brain were determined. Biochemical analysis revealed no hepatocellular injury with minor changes associated with the hepatobiliary system. Minimal changes were found for renal function and the Na+/K+ ratio was reduced in the copper and manganese (Cu + Mn) and copper, manganese, and mercury (Cu, Mn + Hg) groups th...

Involvement of small leucine-rich proteoglycans and telocytes in thin and thick human endometrium: immunohistochemical and ultrastructural examination
Ultrastruct Pathol. 2023 Oct 16:1-11. doi: 10.1080/01913123.2023.2270660. Online ahead of print.ABSTRACTThin endometrium, defined as an endometrial thickness of less than 7 mm during the late follicular phase, is a common cause of frequent cancelation of embryo transfers or recurrent implantation failure during assisted reproductive treatment. Small proteoglycans regulate intracellular signaling cascades by bridging other matrix molecules and tissue elements, affecting cell proliferation, adhesion, migration, and cytokine concentration. The aim of the study is to investigate the role of small leucine-rich proteoglycans in ...

Morphologically and karyotypically atypical cells of 'normal' human bronchial epithelial cell line (Beas-2B)
In this study, atypical cells of the Beas-2B cell line in early passage culture were observed using light and electron microscopy, and the cells were further investigated for abnormal karyotypes by flow cytometry. This Beas-2B cell line could be morphologically categorized into two cell types, A and B. Type A contains a large nucleus and abundant cytoplasm (type A > 95%) and type B contains a small nucleus with dense and scarce cytoplasm (type B < 5%). Both atypical cell types had atypical and multilobed/multinucleated cells, including a high percentage (>30%) of mitotic figures, and were Ki-67 positive (100%). Ka...
