What are the Pterygomaxillary Fracture Patterns in Cleft Orthognathic Surgery?

Background: Patients with cleft lip and palate (CLP) often exhibit unique anatomical variations in the pterygoid plates, which can influence fracture patterns at the pterygomaxillary junction (PMJ) during Le Fort I osteotomy. These differences may increase the risk of unfavorable fractures, complicating surgery and recovery.

Purpose: The study purpose was to measure the association between the osteotomy level with the PMJ fracture patterns in CLP patients undergoing Le Fort I osteotomy.

Comparative Analysis of Methods of Evaluating Human Fatigue.

The present study used four different methods to estimate fatigue. Forty-seven volunteers (45 men and 2 women), 41.3 ± 7.

The correlation between abnormal Krüger strict morphology and the sperm DNA fragmentation index.

Objective: This study aims to investigate whether alterations in sperm DNA fragmentation rates are more frequent when Krüger strict morphology is ≥4% (normal).

Methods: The retrospective study included 132 participants from March 2020 to November 2021. Participants were divided into two groups based on the inclusion criteria: normal and abnormal Krüger strict morphology, with a mean age of 40 years.

Acute low temperature and lipopolysaccharide differentially modulated the innate immune and antioxidant responses in a subtropical fish, the pacu (Piaractus mesopotamicus).

Exogenous factors such as low water temperature can be stressful and elicit negative immune system effects, especially for fish, which are ectothermic. Stress and immune responses require energy overload, which can affect the cellular redox balance, causing oxidative damage. These overall responses impair the animal's health and negatively affect fish farming.

Season changes in performance of upper limbs and trunk in para swimmers.

Objectives: To evaluate upper limb performance, trunk extensor endurance, and serratus anterior strength in para swimmers over a sports season.

Design: A cohort study conducted over eleven months.

Settings: Three assessments were performed at pre-season, mid-season, and post-season, evaluating the CKCUEST, Sorensen Test, and isometric strength of the serratus anterior.
