Sexual Selection and the Evolution of Male Reproductive Traits in Benthic Octopuses

Frontiers in Physiology, 2019
Competition between same-sex organisms, or intra-sexual selection, can occur before and after mating, and include processes such as sperm competition and cryptic female choice.

Plasticity in Sexual Dimorphism Enhances Adaptation of Dioecious Vallisneria natans Plants to Water Depth Change

Frontiers in Plant Science, 2019
Sexual dimorphism in vegetative and reproductive traits is associated with contrasting strategies of males and females for response to varied environmental conditions, causing sex-specific reproduction success and consequently long-distance dispersal and

Electroencephalographic Normalization as a Biomarker of Clinical Recovery in Down Syndrome Regression Disorder

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Down syndrome regression disorder is a syndrome characterized by subacute loss of cognitive, behavioral, and functional abilities in individuals with Down syndrome. Electroencephalography abnormalities are frequently observed during evaluation, but it remains unclear whether these findings represent a dynamic marker of disease ...

Genetic parameters of reproductive traits in pigs: a contribution

Italian Journal of Animal Science, 2003
Generally pig breeding efficiency is defined as the number of piglets weaned per sow per year, so in every pig breeding programmes, great emphasis is placed on improving reproductive traits in sow lines and generally, the evaluation of litter size is carried out in most selection planes. Usually, the reproduction breeding goal is to increase the number

Reserves, Injury Severity, and Outcomes in Traumatic Brain Injury: A CENTER‐TBI Observational Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Reserve refers to the brain's ability to maintain function after an injury and strongly relates to traumatic brain injury (TBI) outcomes. This study examined (1) whether associations between pre‐injury reserve proxies and outcomes differed across injury severity categories, and (2) whether the impact of injury severity varied across ...

Mapping the Social Network Structure and Composition of Black Individuals With Rheumatic and Musculoskeletal Conditions

Arthritis Care &Research, EarlyView.
Objective Our objective was to describe the social networks of Black individuals with rheumatic and musculoskeletal conditions and understand the clustering of health‐related behaviors to inform future community‐based, peer‐led interventions. Methods We used an adapted Personal Network Survey for Clinical Research (PERSNET) to map the personal social ...

Genetic polymorphism of LHX4 gene and its association with growth and reproductive traits in goats of Odisha

Indian Journal of Animal Sciences
The purpose of this study was to investigate the genetic variation in exon 6 of the LHX4 gene in Ganjam and Black Bengal goats. DNA was extracted from the buccal swab samples. By using specific primers, the target partial sixth exon of the LHX4 gene was
