Article Synopsis
  • - This study examined genetic variations in indigenous chickens, specifically focusing on exons 1 and 6, and assessed the relationship between certain genetic markers (SNPs) and egg quality traits.
  • - While most chicken strains followed expected genetic distributions, some showed significant deviations, particularly affecting the TT genotype, hinting at influences like genetic drift and selection.
  • - The research indicated that specific SNPs can negatively or positively impact egg quality, with certain genotypes linked to better eggshell and yolk characteristics, suggesting their potential use in improving egg quality traits through marker-assisted selection (MAS).

Paediatric trigger-locked thumb (PT-LT) is a common paediatric thumb condition. It is an acquired flexion deformity of the interphalangeal joint because of a size mismatch between an enlarged flexor pollicis longus tendon and a stenotic oblique pulley. It may present clinically as paediatric locked thumb which is more common or infrequently as paediatric trigger thumb.

The viscosity of lipid bilayers is a property relevant to biological function, as it affects the diffusion of membrane macromolecules. To determine its value, and hence portray the membrane, various literature-reported techniques lead to significantly different results. Herein we compare the results issuing from two widely used techniques to determine the viscosity of membranes: the Fluorescence Lifetime Imaging Microscopy (FLIM), and Fluorescence Recovery After Photobleaching (FRAP).

Background: Thumb trapeziometacarpal (TM) joint arthrosis is a common cause of thumb pain, which adversely affects hand function. Early arthrosis is characterized by capsular laxity, painful pinch and grip, and physical findings of joint tenderness and laxity. Dorsoradial capsulodesis (DRC) is a surgical technique used to stabilize the TM joint and treat early-stage arthrosis.

Distal radius fractures are among the most common fractures encountered in orthopedic practices. If treated operatively, most implants are retained after the fracture heals unless there is hardware failure, limitation of wrist motion, pain, infection, tendon rupture, or tenosynovitis. Complications have been reported during hardware removal, including not knowing the exact implant prior to its removal.

Background: Rock climbing first evolved as a sport in the late 18th century. With its growing popularity, the number of rock climbing-related injuries has potential to increase, spurring a rise in the number of articles associated with it. Despite the available literature, there remains a paucity of information about upper extremity injuries sustained by rock climbers, and no studies to date have focused on gender-specific injuries.

Hand and wrist injuries in martial arts are typically a reflection of the combat nature of this discipline. In striking sports, the axial load mechanism of injury is common and causes fractures and dislocations; in grappling sports, sprain injuries and degenerative changes predominate. There is clear evidence to support that hand protection reduces the risk of hand injury.
