Changes in sleep patterns in adolescents are more associated with pubertal indicators than age: A perfect storm with a dash of hormones

British Journal of Developmental Psychology, EarlyView.
Abstract As they become older, adolescents tend to prefer sleeping and rising later. Yet, it is still unclear if these sleep changes occur due to advancing age or because adolescents are more pubertally mature. This was investigated cross‐sectionally in a sample of 121 Brazilian 9‐to‐17‐year‐olds.

Fibrous dysplasia of maxilla: Report of two cases

Journal of Indian Academy of Oral Medicine and Radiology, 2015
Fibrous dysplasia (FD) is an idiopathic skeletal disorder in which the trabecular bone is replaced and distorted by poorly organized, structurally unsound fibro-osseous tissue. The lesion is classified into two forms: Monostotic (75-80%) and polyostotic.

Long‐term outcomes of stereotactic radiofrequency ablation in hypothalamic hamartomas: A single‐center experience

Epilepsia, EarlyView.
Abstract Objective Hypothalamic hamartomas (HHs) lead to refractory epilepsy, and minimally invasive surgical approaches are standard of care for affected patients. Stereotactic radiofrequency thermocoagulation (SRT) is one of the treatment methods recognized to achieve seizure freedom. This study reports surgical outcome from a single center reporting

Genetic Parameter Estimation for Pregnancy Loss and Their Association With Reproductive and Growth Traits in Brahman Cattle Under Extensive Tropical Conditions

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT This study estimated genetic parameters for pregnancy loss (PL) in Brahman cattle and evaluated the genetic correlation of PL with growth and reproductive traits using both the pedigree relationship matrix (A) and pedigree plus genomic relationship matrix (H). Data were collected from two herds in Bolivia, focusing on three age groups: heifers,

Stayability in the Era of Early‐Challenged Females: Genetic Parameters and Correlations With Economically Relevant Traits

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT This study aimed to estimate the variance components, heritabilities and genetic correlations between four new different categories of stayability (STAY48‐2, STAY48‐3, STAY54‐2, STAY54‐3) with weight at 240 days of age (W240), weight at 450 days of age (W450), scrotal circumference at 365 days of age (SC365), age at puberty in males (APM ...

Precocidade sexual em bovinos Nelore avaliada por ultrassonografia testicular

Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2014
The present study aimed to evaluate if there are differences in testicular parenchyma echogenicity between pre-pubescent and pubescent animals at the same age. Ultrasound examinations were performed in longitudinal and transversal planes of the testicles

Genetic Parameters of Age at Conception in Nellore Females Using Threshold Models

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Age at conception is a critical factor in the intensification of production systems. It is crucial for intensifying production, optimising reproductive efficiency and boosting Nellore female productivity for genetic progress. However, the low heritability estimates currently limit the effectiveness of selection responses, thereby underscoring ...

Mother-infant relationship in the slender loris (Loris tardigradus lydekkerianus) [PDF]

, 1980
Close observations under caged conditions were made on the behaviour of four mother lorises towards their own and alien infants. There appears to be no mutual recognition between the mother and her infant, and the relationship appears to be less specific.
