The study was carried out to evaluate variability of morpho-genetic potential of plasma rich in thrombocytes. The analysis of ADP-induced aggregation of thrombocytes separated from blood samples of 32 male volunteers aged 18-42 (22±3) was applied. The bimodal character of reaction of thrombocytes to ADP with peaks of aggregation in range of 30-50% and 60-80%. Besides individual differences in range of aggregation differences in time of reaching peak of aggregation and entering plateau were established. In some of volunteers the reversible character of aggregation curve reflecting absence of phase of thrombogenesis stabilization was established. The characteristics of aggregation curve, associated with activation of signal system, launching of degranulation of thrombocytes and exposition of GPIIaIIIb can reflect velocity and effectiveness of secretion of granules of thrombocytes at application of standard doses of stimulants of aggregation. These specifics substantiate necessity of preliminary evaluation of aggregation response of thrombocytes for prognosis of effectiveness of degranulation and release out of granules of thrombocytes biologically active molecules determining morpho-genetic potential of plasma rich with thrombocytes.

Orthobiologic injections including platelet-rich plasma (PRP) and cell-based injections are becoming increasingly popular. Evidence suggests that these therapies can be effective in certain situations. The efficacy of these injections may be more dependent on the quality of the injectate, which given their autologous nature, may be dependent on lifestyle choices like exercise, diet, and supplements.

Female sexual dysfunction is highly prevalent among postmenopausal females approaching 50%, with vulvovaginal atrophy (VVA) being a cardinal sign. For decades, hormone replacement therapy was the only solution to relieve symptoms associated with this atrophy. However, it was limited by its serious side effects, raising the need for new treatment strategies.

Blood microsampling (BμS) has recently emerged as an interesting approach in the analysis of endogenous metabolites but also in metabolomics applications. Their non-invasive way of use and the simplified logistics that they offer renders these technologies highly attractive in large-scale studies, especially the novel quantitative microsampling approaches such as VAMs or qDBS. Herein, we investigate the potential of BµS devices compared to the conventional plasma samples used in global untargeted mass spectrometry-based metabolomics of blood.

Background/objectives: Hyperlipidemia is a serious risk factor for cardiovascular diseases and liver steatosis. In this work, we explored the effect of an herbal formula (CBF) containing immature pods and extracts on lipid metabolism disorders and lipoprotein-rich plasma (LRP) oxidation in mice.
Methods: The phenolic composition was determined using HPLC-DAD analysis.
This meta-analysis focuses on the controversial efficacy and safety of microfragmented adipose tissue (MFAT) as compared with platelet-rich plasma (PRP) in the clinical treatment of knee osteoarthritis (KOA). We have attempted to provide an evidence-based medicine protocol for the conservative treatment of KOA. Researchers collected and compared randomized controlled trials (RCTs) that used microfragmented adipose tissue and platelet-rich plasma to treat knee osteoarthritis.
