Origanum Syriacum Inhibits Proliferation, Migration, Invasion and Induces Differentiation of Human Aortic Smooth Muscle Cells by AlDisi, Sara

“…Cardiovascular diseases (CVDs) are still the number one cause of morbidity and mortality both in Qatar and worldwide. A major risk factor of CVDs is atherosclerosis, the hardening of blood vessels caused by decreased diameter and formation of plaque. …”

Effect of sintering temperature of NBT–6BT lead-free ceramics on the structural, ferroelectric and piezoelectric properties by Slimani, Ahmed

“…The XRD results show that the 850 °C is the best calcination temperature, where the NBT-6BT ceramic had the largest crystallite size with a dense sample, 96% of the theoretical value. However, the density decreased significantly with increasing the calcination temperature above 850 °C due to the secondary phase formation. …”

Identification of an amino-terminus determinant critical for ryanodine receptor/Ca2+ release channel function. by Seidel, Monika

“…Deletion of the β8-β9 sequence produces unstable tetrameric channels with subdued intracellular Ca2+ mobilization implicating a role for this domain in channel opening. The arrhythmia-linked R176Q mutation within the β8-β9 loop decreases N-terminus tetramerization but does not affect RyR2 subunit tetramerization or the N-terminus interaction with C-terminus. …”

Global, regional, and national stillbirths at 20 weeks' gestation or longer in 204 countries and territories, 1990–2021: findings from the Global Burden of Disease Study 2021 by Comfort, Haley

“…The estimated number of stillbirths occurring at 20 weeks' gestation or longer decreased from 5·08 million (95% UI 4·07–6·35) in 1990 to 3·04 million (2·61–3·62) in 2021, corresponding to a 39·8% (31·8–48·0) reduction, which lagged behind a global improvement in neonatal deaths of 45·6% (36·3–53·1) for the same period (down from 4·03 million [3·86–4·22] neonatal deaths in 1990). …”

Mechanical properties and surface characteristics of an AA6060 alloy strained in tension at cryogenic and room temperature by Xu, Zebing

“…The homogeneity in slip behavior introduced more topography at 77 K than observed at 295 K and the enhanced topography might be due to more 3-dimensional (3D) lattice rotation in grains having a high Schmid factor, hence introducing more accumulation of local displacements in the thickness direction.…”
