A subpopulation of tissue remodeling monocytes stimulates revascularization of the ischemic limb.

Despite decades of effort aimed at developing clinically effective cell therapies, including mixed population mononuclear cells, to revascularize the ischemic limb, there remains a paucity of patient-based studies that inform the function and fate of candidate cell types. In this study, we showed that circulating proangiogenic/arteriogenic monocytes (PAMs) expressing the FcγIIIA receptor CD16 were elevated in patients with chronic limb-threatening ischemia (CLTI), and these amounts decreased after revascularization. Unlike CD16-negative monocytes, PAMs showed large vessel remodeling properties in vitro when cultured with endothelial cells and smooth muscle cells and promoted salvage of the ischemic limb in vivo in a mouse model of hindlimb ischemia.

Development of a membrane for guided tissue regeneration: An study.

Aim: The aim of this study was to develop an alternative low-cost membrane for use in guided tissue regeneration (GTR).

Setting And Design: In vitro study.

Methods And Material: In this study, a membrane prepared from a 335 mm sized opening nylon substrate, covered in aqueous resin derived from chitosan, was compared with a commercial material, a non-degradable expanded poly (tetrafluoroethylene).

Influence of STAT4 gene polymorphisms in the pathogenesis of endometriosis.

The STAT4 gene is vital to signaling pathways in the immune response. Immunological alterations are involved in the pathogenesis of endometriosis, and STAT4 polymorphisms may be linked to disease development. This study's aim is to evaluate the possible association between four STAT4 polymorphisms (rs7601754/G > A, rs11889341/C > T, rs7574865/T > G, and rs7582694/C > G) and the pathogenesis of endometriosis in Brazilian women.

The Impact of FSHR Gene Polymorphisms Ala307Thr and Asn680Ser in the Endometriosis Development.

Endometriosis is an estrogen-dependent inflammatory disease that affects a large number of women in reproductive age. Follicle-stimulating hormone (FSH) plays a role in steroidogenesis and acts through a transmembrane glycoprotein, FSH receptor (FSHR). Polymorphisms in FSHR gene were previously associated with variability in FSH serum level and reproductive outcomes, but its relation with endometriosis has not been clarified and demonstrated conflicting results, ranging from strong links to no association to endometriosis.

Extravascular renal denervation ameliorates juvenile hypertension and renal damage resulting from experimental hyperleptinemia in rats.

Background: Material obesity in rodents is associated with neonatal hyperleptinemia and hypertension of sympathetic origin in adult offspring. Previously, we reported that experimentally induced hyperleptinemia in rat pups results in adulthood hypertension. Here, we addressed the hypothesis that experimental neonatal hyperleptinemia, through renal nerve activation, adversely affects adult renal function.
