Biochemical, immunological markers, histology and ultrastructural changes of open wound healing in rats treated with ethyl acetate extract of rhizomes.

Research on plant-based wound healing agents has been one of the current developing areas in modern biomedical science. This study aimed to assess the effects of ethyl acetate extract of rhizome (ZZRE) on open wound healing activity in Wistar rats. Ninety male Wistar rats (220-320 g) were divided into three groups treated with phosphate buffered saline (PBS) (negative control), Solcoseryl gel (positive control), and 10 % ZZRE (treatment group), respectively.

A rare nasal fibrosarcoma: A case report.

Introduction: Fibrosarcoma is a malignant neoplasm, with nasal localization uncommon. Clinically, the main symptoms are epistaxis and nasal obstruction. Microscopically, it is characterized by a dense proliferation of fibroblasts with a herringbone pattern and spindle-shaped cells with hyperchromatic nuclei.

Cellular and DNA Toxicity Study of Triphenyltin Ethyl Phenyl Dithiocarbamate and Triphenyltin Butyl Phenyl Dithiocarbamate on K562, Leukemia Cell Line.

Introduction: Continuous research for new effective drugs to treat cancer has improved our understanding on the mechanism of action of these drugs and paved new potential for their application in cancer treatments. In this study, organotin compounds known as triphenyltin ethyl phenyl dithiocarbamate and triphenyltin butyl phenyl dithiocarbamate were investigated for their toxicity on leukemia cell line (K562) and non-cancerous cell line (Chang liver cell and lung fibroblast, V79 cell).

Methods: MTT assay was performed to evaluate the cytotoxic effects of both compounds toward the cells after 24, 48 and 72 hours of exposure or treatment.

Lysosomal dysfunction induced cytosolic vacuolation and increased intracellular amyloid-beta 42 (Aβ42) in human brain endothelial cells (HBEC-5i).

Lysosome is a primary degradative organelle and is crucial in cellular homeostasis. A reduction in its function due to ageing has been associated with the development of Alzheimer's disease (AD), a common neurodegenerative disorder characterised by the deposition of neurotoxic amyloid plaque in the brain and cerebral vessel walls. The breakdown of the blood-brain barrier (BBB) plays a vital role in the pathogenesis of AD.
