Plasma volume variations in response to high intensity interval training in obese women: The influential role of menopausal status and age
Published 2025“…For all women pre- and post-HIIT comparisons revealed significant differences in the extent of PV reduction at all two points (P < 0.01). Multiple linear regression analysis revealed that age was a significant contributor to the decreases in plasma volume (PV) observed both after warm-up and following the supramaximal cycling test - SCT (r = 0.44 and r = 0.57). …”

Experimental results and modelling of corrosion-damaged concrete beams strengthened with externally-bonded composites
Published 2018“…The FE models were able to capture the non-linear behavior of the strengthened beams. The interfacial bond stress-slip models at the fabric/matrix and composite/concrete interfaces and the number of composite layers had the most significant impact on the predicted response of the strengthened beams whereas the corrosion level, modeled as a reduction in the steel reinforcement cross-section, showed a slight effect on their performance. …”

Insights Into the Role of CircRNAs: Biogenesis, Characterization, Functional, and Clinical Impact in Human Malignancies
Published 2021“…Because of the structural stability, high expression, availability of microRNA (miRNA) binding sites and tissue-specific expression, circRNAs have become hot topic of research in RNA biology. Compared to the linear RNA, circRNAs are produced differentially by backsplicing exons or lariat introns from a pre-messenger RNA (mRNA) forming a covalently closed loop structure missing 3′ poly-(A) tail or 5′ cap, rendering them immune to exonuclease-mediated degradation. …”

Independent and combined effects of antioxidant supplementation and circuit resistance training on selected adipokines in postmenopausal women
Published 2019“…These findings suggest that Zataria Multiflora supplementation by itself has little effect on measured adipokines; however, its combination with CRT produced noticeable effects on circulating levels of these adipokines, even more than CRT alone. Consequently, a combination of CRT and Zataria Multiflora supplementation may represent a potentially beneficial non-pharmacologic intervention on some selected adipokines in postmenopausal women.…”
