The aim was to evaluate the quality of the sheep skin of different sex classes submitted to different levels of feed restriction. Sheep without defined racial pattern of different sex classes (15 non-castrated males, 15 castrated males and 15 females), with initial body weight of 18.1 ± 0.4 kg and mean age of 90 days were distributed in a factorial 3 × 3, with three sex classes and 3 levels of feed restriction (ad libitum intake and restricted intake at 70 and 80%), with 5 repetitions. After slaughter, the skins were collected for physical-mechanical tests. The effect of the sex classes x levels of dietary restriction interaction was observed for transverse thickness and longitudinal rupture elongation (p < 0.05). Animals fed ad libitum had greater longitudinal transverse thickness (p < 0.05). Animals fed ad libitum and 70% feed restriction showed greater transverse elongation at break (p < 0.05). As for the difference between sex classes in the transverse thickness variable for tearing strength, the interaction sex classes x levels of feed restriction for transverse thickness, longitudinal thickness, transverse tearing strength and longitudinal tearing strength occurred (p < 0.05). Feed restriction reduces the physical quality of the skin of sheep of different sex classes, and the use of castrated male sheep in positive energy balance is recommended to obtain leather with greater thickness, longitudinal rupture elongation and transverse tear strength.

Blood transfusions in craniotomy for tumor resection: Incidence, risk factors, and outcomes.

Background: Blood transfusions (BT) are often needed in neurosurgical procedures, especially craniotomies for tumor resections, due to risks of anemia, ischemic brain injury, and hemorrhage. However, BT may increase the risk of perioperative complications. This study aimed to determine the incidence, associated factors, and outcomes of BT in patients undergoing craniotomy for intracranial tumor resection.

Background & Aims: Suboptimal diets increase morbidity and mortality risk. Epigenetic clocks are algorithms that can assess health and lifespan, even at a young age, before clinical manifestations of diseases. We investigated the association between dietary patterns and biological aging in young adult twins.

Recent advances in artificial intelligence (AI) and machine learning (ML) applications have elevated accomplishments in various scientific fields, primarily those that benefit the economy and society. Contemporary threats, such as armed conflicts, natural and man-made disasters, and illegal immigration, often require fast and innovative but reliable identification aids, in which forensic anthropology has a significant role. However, forensic anthropology has not yet exploited new scientific advances but instead relies on traditionally used methods.

Introduction: The primary objective of this study was to assess the 3-dimensional position of the mandibular canal (MC) in different craniofacial patterns to know about the safe placement of temporary skeletal anchorage devices using cone-beam computed tomography (CBCT). The secondary objectives were to assess sex differences and correlate the MC position with various factors.
Methods: This prospective, observational study was conducted on 90 patients, divided into 3 groups based on the sagittal pattern: skeletal Class I, Class II, and Class III.
