Hyperactivation and Tyrosine Phosphorylation of Cryopreserved Stallion Spermatozoa in Relation to Conventional In Vitro Fertilization Blastocyst Production

open access: yesAndrology, EarlyView.
ABSTRACT Background Challenges in establishing clinical conventional in vitro fertilization (IVF) in horses include variation in sperm and oocyte quality, which can be affected by mare age. Extended preincubation of stallion spermatozoa has resulted in successful IVF.

Lactate‐Responsive Glycogen Dynamics Are Associated With Bull Sperm Motility and Fertilization Under Glucose‐Limited Conditions

open access: yesAndrology, EarlyView.
ABSTRACT Background Mammalian sperm need to undergo hyperactivation, capacitation, and acrosome reaction to achieve fertilization competence. However, the female reproductive tract presents contrasting metabolic environments. The uterus is glucose‐rich, and the oviduct is lactate‐rich and glucose‐limited.

Early Hospital Practices Were Associated With Exclusive Breastfeeding Among Late Preterm and Early Term Infants

open access: yesActa Paediatrica, EarlyView.
ABSTRACT Aim To assess how maternal/infant characteristics and early hospital practices influenced exclusive breastfeeding at 2–3 weeks postpartum among mothers intending to breastfeed their late preterm and early term infants. Methods This secondary analysis used data from a randomised controlled trial of 72 mothers of late preterm (34 + 0–36 + 6) and

Postnatally Acquired Cytomegalovirus Infection in Extremely Premature Infants: A Prospective Observational Cohort Study

open access: yesActa Paediatrica, EarlyView.
ABSTRACT Aim Postnatally acquired cytomegalovirus (pCMV) infection may cause severe disease in extremely preterm infants, but its clinical significance remains uncertain. We investigated the incidence, timing, disease burden, and diagnostic performance of saliva screening. Method In this prospective cohort study, infants born at < 28 weeks of gestation

Trace Element Patterns in Juvenile Wild Chimpanzee Dentitions

open access: yesArchaeometry, EarlyView.
ABSTRACT Trace elements are used to infer mammalian early‐life diets, environmental toxins, dispersal patterns, stress histories, and weaning ages. Here, we employ laser ablation‐inductively coupled plasma‐mass spectrometry (LA‐ICP‐MS) to reveal elemental patterns in our closest living relatives, chimpanzees.
