The Dual Faces of Oestrogen: The Impact of Exogenous Oestrogen on the Physiological and Pathophysiological Functions of Tissues and Organs.

Oestrogen plays a crucial physiological role in both women and men. It regulates reproductive functions and maintains various non-reproductive tissues through its receptors, such as oestrogen receptor 1/oestrogen receptor α (ESR1/Erα), oestrogen receptor 2/oestrogen receptor β (ESR2/Erβ), and G protein-coupled oestrogen receptor 1 (GPER). This hormone is essential for the proper functioning of women's ovaries and uterus.

Increased apoptosis of CD20+ IgA + B cells is the basis for IgA deficiency: the molecular mechanism for correction in vitro by IL-10 and CD40L.

IgA deficiency is the most common primary immunodeficiency in humans. Comparative analysis of gene expression in PBMC from IgA-deficient (IgAd) and normal donors using functional multiplex panels showed overexpression of the Caspase-1 (CASP-1) gene. Cells from all the IgAd donors (n=7) expressed 4-10-fold caspase-1 mRNA over normal controls (n=5).

Effects of rejuvenation and frozen storage on 42-day-old AS-3 RBCs.

Background: A storage period of 42 days has been approved by the FDA for RBCs stored in NUTRICEL (AS-3). This study was undertaken to provide data to the FDA about the feasibility of salvaging AS-3 RBCs at the end of their storage period by rejuvenation and freezing, and to evaluate the effect of rejuvenation on indicators of RBC function.

Study Design And Methods: Healthy adults (n = 22) donated 450 mL of whole blood, and RBC components were prepared at two study sites.

Low-dose total body irradiation followed by allogeneic lymphocyte infusion may induce remission in patients with refractory hematologic malignancy.

Allogeneic stem cell transplantation is curative for certain cancers, but the high doses of chemotherapy/radiotherapy lead to toxicity. Here, we treat patients with refractory cancer with 100 cGy total body irradiation (TBI) followed by infusion of nonmobilized pheresed allogeneic peripheral blood cells. Twenty-five patients, with a median age of 47 years, with refractory cancers were enrolled.
