Article Abstract
Hepatocellular carcinoma (HCC) is a common cancer world-wide with a higher incidence in Asia. Clear cell variant of HCC (CCHCC) has a frequency ranging from 0.4% to 37%. The presence of 90-100% clear cells is rare. In the present case, a 35-year-old female patient presented with fever and a large abdominal mass in the right hypochondrium. Histology of the tumor revealed >95% clear cells and after taking multiple sections from different areas of tumor only few scattered cells with eosinophilic cytoplasm were found. Immunohistochemistry with Hep Par 1, Glypican 3 and polyclonal carcinoembryonic antigen were negative as were all other markers for metastatic clear cell tumors. Histological diagnosis was based on routine H and E sections showing a histological pattern of architecture with thickened trabeculae. We describe a rare case of CCHCC with >95% clear cells and no immunoreactivity in tumor cells in a non-cirrhotic liver.

Inhibition of Endothelial-Mesenchymal Transition Mediated by Activin Receptor Type IIA Attenuates Valvular Injury Induced by Group A Streptococcus in Lewis Rats.
Front Biosci (Landmark Ed)

Department of Cardiology, The First Affiliated Hospital of Guangxi Medical University, 530021 Nanning, Guangxi, China.
Background: Rheumatic heart disease (RHD), which is caused mainly by Group A Streptococcus, leads to fibrotic damage to heart valves. Recently, endothelial‒mesenchymal transition (EndMT), in which activin plays an important role, has been shown to be an important factor in RHD valvular injury. However, the mechanism of activin activity and EndMT in RHD valvular injury is not clear.

Cardiovascular disease (CVD) is the most prevalent cause of mortality and morbidity in the Western world. A common underlying hallmark of CVD is the plaque-associated arterial thickening, termed atherosclerosis. Although the molecular mechanisms underlying the aetiology of atherosclerosis remain unknown, it is clear that both its development and progression are associated with significant changes in the pattern of DNA methylation within the vascular cell wall.

Until recently, the only methods for finding out if a particular strain or species of bacteria could be a host for a particular bacteriophage was to see if the bacteriophage could infect that bacterium and kill it, releasing progeny phages. Establishing the host range of a bacteriophage thus meant infecting many different bacteria and seeing if the phage could kill each one. Detection of bacterial killing can be achieved on solid media (plaques, spots) or broth (culture clearing).

The effectiveness of ultraviolet-C light-emitting diodes (UVC LEDs) is currently limited by the lack of suitable encapsulation materials, restricting their use in sterilization, communication, and in vivo cancer tumor inhibition. This study evaluates various silicone oils for UVC LED encapsulation. A material aging experiment was conducted on CF1040 (octamethylcyclotetrasiloxane), HF2020 (methyl hydro polysiloxanes), and MF2020-1000 (polydimethylsiloxane) under UVC radiation for 1000 h.

Department of Plastic and Reconstructive Surgery, Peninsula Health, Melbourne, VIC 3199, Australia.
Basal cell carcinoma (BCC), the most common skin malignancy, typically occurs in sun-exposed areas but can develop in atypical locations, such as scars, burns, and skin graft donor sites. BCC arising specifically in full-thickness skin graft donor sites is exceptionally rare. This study presents a unique case of BCC occurring 16 years post-graft harvesting and provides a comprehensive literature review to analyze clinical patterns, possible etiopathogenesis, and treatment strategies.
