Sperm Telomere Interactions Are Impaired in Testicular Cancer Before and After Adjuvant Therapy

open access: yesAndrology, EarlyView.
ABSTRACT Background No study has yet explored telomere length or interaction in sperm nuclei of testicular cancer (TC) patients exposed to chemotherapy or radiotherapy. However, sperm telomere dynamics have emerged as a potential marker in male infertility.

Central Precocious Puberty: Update on Diagnosis and Treatment [PDF]

open access: yes, 2015
Central precocious puberty (CPP) is characterized by the same biochemical and physical features as normally timed puberty but occurs at an abnormally early age. Most cases of CPP are seen in girls, in whom it is usually idiopathic.

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

open access: yesBritish 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

open access: yesJournal 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.

Spectrum of Hypogonadism and Its Management in Adolescents With Prader‐Willi Syndrome: A Retrospective Cohort Study Over 35 Years

open access: yesClinical Endocrinology, EarlyView.
ABSTRACT Context Adult data indicate that hypogonadism is underdiagnosed and undertreated in Prader‐Willi Syndrome (PWS). Objectives We aimed to describe the spectrum of pubertal development, and the diagnosis and treatment of hypogonadism in paediatric/adolescent patients with PWS. Design/Patients A retrospective cohort study of patients with PWS aged

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

open access: yesJournal 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 ...

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

open access: yesJournal 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 ...
