On Postponement and Birth Intervals [PDF]

, 2008
Much of the literature on fertility transition presumes that birth control is practiced either to limit family size or to space births. This article argues that women also use birth control to postpone pregnancy.

Placental size at birth.

South African medical journal = Suid-Afrikaanse tydskrif vir geneeskunde, 1979
The placentas of 1,081 infants born to Coloured primigravidas in Cape Town were examined. The values for gross and trimmed placental weight, chorionic surface area and thickness are given for each week of gestation from 32 to 41 weeks. These results indicate the pattern of placental growth and provide a basis for further studies to evaluate deviations ...

Customized versus population birth weight charts for identification of newborns at risk of long-term adverse cardio-metabolic and respiratory outcomes: a population-based prospective cohort study

BMC Medicine, 2019
Background Customized birth weight charts take into account physiological maternal characteristics that are known to influence fetal growth to differentiate between physiological and pathological abnormal size at birth.

Birth size and the serum level of biological age markers in men

Scientific Reports, 2023
Previous studies showed that intrauterine growth restrictions, resulting in smaller body size at birth, are associated with altered development and the risk of age-related diseases in adult life.

Structures of mycobacterial 3‐methylcrotonyl‐CoA carboxylase reveal carrier‐domain translocation between catalytic sites

FEBS Letters, EarlyView.
Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation

FEBS Letters, EarlyView.
Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...

EFFECT OF INBREEDING ON THE PERFORMANCE OF LARGE WHITE YORKSHIRE SOWS [PDF]

Journal of Veterinary and Animal Sciences, 2004
Data relating to 130 sows, 19 boars from 400 farrowings spread over a period from 1984 to 1992 were utilized to study genetic and non-genetic effects on variation of litter size at birth and litter size at weaning.

Assessing the Causal Relationship of Maternal Height on Birth Size and Gestational Age at Birth: A Mendelian Randomization Analysis.

PLoS Medicine, 2015
BackgroundObservational epidemiological studies indicate that maternal height is associated with gestational age at birth and fetal growth measures (i.e., shorter mothers deliver infants at earlier gestational ages with lower birth weight and birth ...
