Effect of aromatase inhibitors on sex differentiation and embryonic development in chicks.

Background: Sexual differentiation can occur after exposure to aromatase into the left gonad at 6.5 days of incubation. Aromatase inhibitors work by inhibiting the action of the aromatase, which converts androgens into estrogens by a process called aromatization.

Effect of exposure to different light colors on embryonic development and neurophysiological traits in the chick embryo.

Background And Aim: Many environmental factors exist that influence embryonic development which is missing in the poultry industry, such as light in incubation facilities or hatcheries. Light plays an important role in the growth and development of chick embryos, whereas dark environments can lead to hatching failure or embryo distortion. Therefore, this study aimed to demonstrate the importance of light and its various colors on the growth and development of broiler chick embryos.

Co-Inheritance of α-thalassemia gene mutation in patients with sickle cell Disease: Impact on clinical and hematological variables.

Background: Sickle cell disease (SCD) is a monogenic, phenotypically highly variable disease with multisystem pathology. The phenotypic heterogeneity of SCD is attributed to environmental and genetic factors such as fetal hemoglobin and co-inheritance of α-thalassemia.

Objectives: To look for different types of α-thalassemia gene mutations among SCD patients and evaluate the influence of the co-inheritance of α-thalassemia on clinical and hematological variables.

Uvulopalatopharyngoplasty.

Uvulopalatopharyngoplasty is a generally safe and widely accepted surgical procedure for the treatment of obstructive sleep apnea. Unfortunately, uvulopalatopharyngoplasty does not always result in success, and patients who initially experienced improvement in the severity of their obstructive sleep apnea may relapse. Proper patient selection and performing uvulopalatopharyngoplasty in conjunction with other surgical procedures that are directed at other sites of upper airway collapsibility may yield favorable outcomes.

Clinical accuracy and reproducibility of virtual interocclusal records.

Statement Of Problem: Although in vitro studies have investigated the accuracy of virtual interocclusal records, clinical research on their ability to register virtual dental casts accurately is lacking.

Purpose: The purpose of this clinical study was to evaluate the accuracy and reproducibility of the virtual interocclusal records of an intraoral scanning system compared with conventional polyvinyl siloxane (PVS) interocclusal records.

Material And Methods: Three conventional interocclusal records followed by 3 virtual interocclusal records per side per participant were made in 10 participants.
