OBJECTIVES Birth season is related to a variety of later outcomes. Among them, mortality is of great interest because it represents lifetime health outcomes. We examined the relationship between birth season and mortality in the US. METHODS We merged the US National Health Interview Survey (NHIS) and NHIS public-use linked mortality files and analyzed 17,082 men and 19,075 women who were foll...
The present study was conducted with an aim to access the incidence of peri-parturient reproductive disorders and to determine the seasonal calving pattern in cross bred cows of Jammu region. A total of 2638 calving records of cross bred dairy cows between 2010 – 2016 were screened retrospectively for peri-parturient reproductive disorders. The most common reproductive problems recorded in the ...
BACKGROUND It has been suggested that season of birth might influence the susceptibility to cataract in later life. METHODS This hypothesis was investigated using data pooled from two case-control studies carried out in Oxfordshire. RESULTS/CONCLUSION The results showed no relation between month or season of birth and cataract in later life in an English population.
Environmental conditions experienced in early life can influence an individual's growth and long-term health, and potentially also that of their offspring. However, such developmental effects on intergenerational outcomes have rarely been studied. Here we investigate intergenerational effects of early environment in humans using survey- and clinic-based data from rural Gambia, a population expe...
BACKGROUND Animal studies have revealed seasonal patterns in cerebrospinal fluid (CSF) monoamine (MA) turnover. In humans, no study had systematically assessed seasonal patterns in CSF MA turnover in a large set of healthy adults. METHODOLOGY/PRINCIPAL FINDINGS Standardized amounts of CSF were prospectively collected from 223 healthy individuals undergoing spinal anesthesia for minor surgical...
The aim of this research was to investigate the calving season effect on some of the productive traits including milk production, fat percentage and some of reproductive traits including pregnancy period and calf birth weight and also estimation of genetic parameters of studied traits too. In this study the data of 22360 Holestein dairy cows form Tehran province’s 65 herds of between 2012 ...
OBJECTIVE We investigated the relationship between influenza seasonality and outcome of very low birth weight infants (VLBWI) in a large observational cohort study of the German Neonatal Network. MATERIALS AND METHODS Within the observational period (July 2009 until December 2014), five influenza seasons occurred (mean duration: 97 days, range: 48-131 days). We stratified VLBWI (n = 10,187) a...
A study to evaluate the reproductive performance of Abergelle goat was carried out at Sekota District of Amhara National Regional State. On-farm flocks from two peasant associations were monitored for two years to collect data. Data collected included identification number of doe and kid, birth / kidding date, kid birth weight, sex of kid, post partum doe weight, litter size, parity of doe. Dat...
The data on 6772 growth records of Sirohi goats maintained at All India Coordinated Research Projecton Sirohi goat at Livestock Research Station, Vallabhnagar, Udaipur, India, and recorded between 2004 and 2016, were analysed to study the growth related traits and their genetic control. The overall least squares means of body weight at birth, W3M, W6M, W9M, W12M, were 2.34 ± 0.03, 12.44 ± 0.19,...
