Ultrasonography Guided Gestational Age Estimation Using Transcerebellar Diameter in Third Trimester Pregnancy

Journal of Nobel Medical College
Background: The correct estimation of gestational age is of great importance for managing pregnancy. Determining gestational age by the first-trimester scan is considered the gold standard, but classical calculation from the last menstrual period is also

Mechanisms and Pathophysiological Significance of Insulin Resistance in Offspring With Intrauterine Growth Restriction Mediated by Hepatic GR/miR‐1224 Programming

Advanced Science, EarlyView.
This work found that early‐stage insulin sensitization but late‐stage insulin resistance in prenatal caffeine exposure (PCE)‐ induced intrauterine growth restriction (IUGR) offspring may be related to the hepatic AGEs accumulation via intrauterine GR/miR‐1224 programming by glucocorticoids.

PIEZO Force Sensing in Vascular Biology: An Explosion of New Knowledge, Concepts and Opportunity

Advanced Science, EarlyView.
Knowledge of the remarkable mechanical force sensing and electrically transducing PIEZO1 and PIEZO2 channels is discussed across vascular biology and its cell types from the embryonic to adult stages in health, disease and old age. How the channels work, relate to other factors and signal for tissue responses to mechanical forces is debated.

Enhanced Selenium Supplement Extends Lifespan and Delays Multi‐Organs Aging by Regulating the Sik1 Pathway Through Maintaining Calcium Homeostasis

Advanced Science, EarlyView.
Aging involves physiological decline and heightened disease susceptibility, necessitating effective interventions. Redox‐responsive selenium‐loaded nanoparticles (SeMSNs) are developed, which delay cellular senescence by reducing oxidative stress and senescence markers (p16/p21). In aged mice, SeMSNs extend lifespan, improve organ function, and restore

On the use of the outcome variable “small for gestational age” when gestational age is a potential mediator: a maternal asthma perspective

BMC Medical Research Methodology, 2017
Background The variable “small for gestational age,” frequently defined as birth weight below the 10th percentile in a gestational age and sex-normalized population, is nowadays generally perceived as a more adequate measure than birth weight or low ...

Long-term trends in the longevity of scientific elites: evidence from the British and the Russian academies of science.

, 2011
National science academies represent intellectual elites and vanguard groups in the achievement of longevity. We estimated life expectancy (LE) at age 50 of members of the British Royal Society (RS) for the years 1670-2007 and of members of the Russian ...
