Lipid content and G6PDH activity in relation to ooplasm morphology and oocyte maturational competence in the domestic cat model.

The aim of the study was to investigate the relationship between ooplasm morphology, lipid content, glucose-6-phosphate dehydrogenase activity (G6PDH) and maturation potential of domestic cat oocytes. Cumulus-oocyte complexes were classified according to ooplasm morphology: evenly dark (dCOC), heterogeneous/mosaic (hCOC), or light/transparent (lCOC), however only dCOCs are thought to be the best-quality, the remaining ones are usually rejected, therefore little is known about their intracellular properties. Lipid droplets (LDs) were visualized and quantified using Oil Red O.

Novel pathological variants of NHP2 affect N-terminal domain flexibility, protein stability, H/ACA Ribonucleoprotein (RNP) complex formation and telomerase activity.

Telomere biology disorders (TBDs) are characterized by short telomeres, premature aging, bone marrow failure and cancer predisposition. Germline mutations in NHP2, encoding for one component of the telomerase cofactor H/ACA RNA binding complex together with Dyskerin, NOP10 and GAR1, have been previously reported in rare cases of TBDs. Here, we report two novel NHP2 variants (NHP2-A39T and NHP2-T44M) identified in a compound heterozygous patient affected by premature aging, bone marrow failure/myelodysplastic syndrome and gastric cancer.

[Treatment of varicose ulcers with Codogard of Polish production].

Synthetic skin CODOGARD produced by the Research and Development Centre of the Knitting Industry in Lódź was applied in 125 cases of the shank varicose ulcer treated in the Clinic of General Surgery of the Warsaw Medical Academy. Two different types of CODOGARD were used for evaluation: the first one without antibacterial dripping, and the second one with antibacterial dropping Sterinol. On the basis of achieved results it was established that CODOGARD was a successful medicine for the crus varicose ulcer.
