Article Abstract
We developed a fluorescent pH probe (1) capable of two-photon excitation and far-visible-emission based on FRET, composed of naphthalimide-piperazine-rhodamine. It exhibited a pH-dependent reversible and fast ratiometric fluorescence change in the rhodamine emission. Probe 1 was applied to image the pH perturbations of mitochondria in living cells and tissues.

3-O-sulfation of heparan sulfate (HS) is the key determinant for binding and activation of Antithrombin III (AT). This interaction is the basis of heparin treatment to prevent thrombotic events and excess coagulation. Antithrombin-binding HS (HSAT) is expressed in human tissues, but is thought to be expressed in the subendothelial space, mast cells, and follicular fluid.

Adrenal lipomas are benign tumors containing ectopic adipose tissue in the adrenal gland, an organ that normally lacks both adipocytes and their progenitors. The origin of this ectopic fat remains enigmatic, and the absence of a genetic animal model has hindered its investigation. Phosphatidylinositol 3,4,5-trisphosphate [PI(3,4,5)P], a key signaling lipid that regulates cellular growth and differentiation, is tightly regulated by the lipid phosphatases PTEN (phosphatase and tensin homolog) and SHIP2 (SH2-containing inositol phosphatase 2).

Background: Sjögren's syndrome (SS) is a chronic autoimmune disease delineated by excessive lymphocyte infiltration to the lacrimal or salivary glands, leading to dry eye and dry mouth. Exosomes secreted from mesenchymal stem cells (MSC) are known to have anti-inflammatory and tissue regeneration abilities. This study endeavored to demonstrate the effect of MSC-derived exosomes on the clinical parameter of dry eyes and associated pathology in SS mouse model.

S100 protein family members S100A8 and S100A9 function primarily as a heterodimer complex (S100A8/A9) in vivo. This complex has been implicated in various cancers, including gastric cancer (GC). Recent studies suggest that these proteins play significant roles in tumor progression, inflammation, and metastasis.

The present study aimed to (1) evaluate the effects of different concentrations of the polysaccharide extract of Cissus sicyoides (PE-Cs) during in vitro culture of preantral follicles included in goat ovarian tissue on (i) follicular morphology and activation, (ii) ovarian stromal density, (iii) follicular and oocyte diameters, (iv) antioxidant enzymes activity (SOD, CAT, and GPx), (v) quantification of MDA, thiol, and nitrite levels; as well as to (2) measure the total antioxidant capacity of the extract. The ovarian cortex fragments were cultured at 39 °C in a humidified atmosphere with 5% CO for 6 d in alpha-modified minimum essential medium (αMEM) supplemented with insulin, transferrin, and selenium; hypoxanthine; glutamine; and bovine serum albumin, which was called αMEM alone or added of PE-Cs at 20, 40, or 80 µg/mL. At the end of the culture period, a reduction in the percentage of normal follicles in all treatments using PE-Cs compared to fresh control and αMEM.
