The functional films based on chitosan and corn starch incorporated tea polyphenols were developed through mixing the solution powder of by casting method. objective this research was to investigate effect different concentrations properties films. Attenuated total reflectance Fourier transform infrared spectrometry X-ray diffraction used potential interactions among chitosan, in blend Physical films, including density, moisture content, opacity, color, water solubility swelling, as well...

Abstract In vitro-cultured oocytes are separated from the follicular micro-environment in vivo and more vulnerable than to changes external environment. This vulnerability disrupts homeostasis of intracellular environment, affecting oocyte meiotic completion, subsequent embryonic developmental competence vitro. Glycine, one main components glutathione (GSH), plays an important role protection porcine However, protective mechanism glycine needs be further clarified. Our results showed that...

Novel porous chitosan microspheres were successfully produced by a freezing–lyophilization drying method in this study and then used as adsorbents to remove toxic iron metal, hexavalent chromium (Cr(VI)). The effects of the concentration solution, syringe diameter, freezing time on morphologies characterized. metal ion adsorption for Cr(VI) was also studied. Results showed that hydrogel beads at temperature −20 °C subsequently lyophilizing frozen structure allowed easily obtain with rough...

The endoplasmic reticulum (ER) is a multifunctional organelle in the cytoplasm that plays important roles female mammalian reproduction. and mitochondria interact to maintain normal function of cells by maintaining intracellular calcium homeostasis. As proven previous research, glycine (Gly) can regulate free concentration ([Ca2+]i) enhance mitochondrial improve oocyte maturation vitro. effect Gly on ER during vitro (IVM) not clear. In this study, we induced an stress model with thapsigargin...

Mitochondria play an important role in controlling oocyte developmental competence. Our previous studies showed that glycine (Gly) can regulate mitochondrial function and improve maturation vitro. However, the mechanisms by which Gly affects during vitro have not been fully investigated. In this study, we induced a damage model oocytes with Bcl-2-specific antagonist ABT-199. We investigated whether could reverse dysfunction caused ABT-199 exposure it is related to calcium regulation. results...

Abstract Heat stress (HS) affects the development of porcine gametes and embryos negatively, induces decrease reproductive ability significantly, threatens global pig production. Ginsenoside Re (GRe), is a main bioactive component ginseng, shows very specific anti‐apoptotic, antioxidant anti‐inflammatory activities. To investigate alleviating effect GRe on in vitro maturation oocyte under HS, polar body extrusion rate, intracellular levels reactive oxygen species (ROS) glutathione (GSH), ATP...
