Vascular smooth muscle cells (SMCs) express membrane-type matrix metalloproteinases-1 and -3 (MT1- and MT3-MMPs). Expression is induced by PDGF in culture or by balloon injury in rat carotid arteries. In this study, we tried to define their functions in SMCs by transducing MT1- and MT3-MMP cDNAs into baboon-cultured SMCs, using adenoviral vectors. Overexpression of MT1-MMP increased the conversion of proMMP-2 to the activated form. In contrast, in MT3-MMP overexpressing cells, MMP-2 activation was partial. However, both MT1- and MT3-MMP overexpression elicited morphological alterations (cell rounding), which was prevented by BB94 addition. The cells, which underwent this change, showed reduced adhesion to matrices and increased migration in a Boyden chamber.

Accessory Cavitated Uterine Malformation (ACUM): An Underdiagnosed, Treatable Cause of Dysmenorrhea.

Department of Obstetrics and Gynaecology, Tata Main Hospital, Jamshedpur, IND.
An uncommon and recently identified Müllerian anomaly is the accessory cavitated uterine mass (ACUM). It is distinguished by the presence of a noncommunicating auxiliary cavity inside the uterus, located near and surrounded by uterine smooth muscle, and bordered by functioning endometrium beneath the round ligament's insertion, with a perfectly healthy uterus, ovaries, tubes, and cavity. Given that it is a congenital ailment with a persistent Müllerian duct at the level of the round ligament, primarily resulting from gubernaculum dysfunction, it usually manifests clinically as childhood dysmenorrhea in girls.

Although LFH is associated with increased fibrosis in the dorsal layer, comprehensive research exploring the characteristics of the ECM and its mechanical properties in both regions is limited. Furthermore, the distribution of fibrosis-associated myofibroblasts within LFH remains poorly understood.

The pathophysiological relationship between wound healing impairment and diabetes is an intricate process. Burn injury among diabetes patients leads to neurological, vascular, and immunological abnormalities along with impaired activities of cell proliferation, collagen production, growth factors, and cytokine activities with huge bacterial infestation. In our study, we aimed to achieve a burn wound dressing material with the help of electrospun Chitosan/Polyethylene oxide/Rosmarinic acid (CS/PEO/RA) nanofibers.

Background And Aim: Our previous research indicates that sarcoplasmic/endoplasmic reticulum calcium ATPase 2 (SERCA2) dysfunction facilitates the phenotypic transformation of aortic smooth muscle cells (ASMCs) and intensifies aortic aneurysm through the regulation of calcium-dependent pathways and endoplasmic reticulum stress. Our hypothesis is that additional mechanisms are involved in aortic aneurysm and atherosclerosis induced by SERCA2 dysfunction from the perspective of ASMC phenotypic transformation.
Methods & Results: In SERCA2 dysfunctional mice and their control littermates, ASMCs were isolated to analyze protein expression and cell functions, and angiotensin II was infused into these mice that were backcrossed into LDL receptor deficient background to induce aortic aneurysm and atherosclerosis.
