The influence of L-proline and fulvic acid on oxidative stress and semen quality of buffalo bull semen following cryopreservation.

Background: This study investigates the effects of cryopreservation and supplementation of Azeri water buffalo's semen with proline (Lp) and fulvic acid (FA).

Objectives: Therefore, this study aimed to assess motility parameters, sperm viability, oxidative stress parameters, and DNA damage to detect the optimum concentrations of Lp and FA for buffalo semen cryopreservation.

Methods: Thirty semen samples of three buffalo bulls were diluted in Tris-egg yolk extender and divided into 12 equal groups including control (C), Lp-10, Lp-20, Lp-40, Lp-60, Lp-80 (containing 10, 20, 40, 60, 80 mM L-proline, respectively), FA-0.

Reducing oxidative stress by κ-carrageenan and C60HyFn: The post-thaw quality and antioxidant status of Azari water buffalo bull semen.

Azeri water buffalo is a species of great interest due to the high quality of its products such as milk. Due to the decreasing trend of its number and risk of extinction in the future, our attention is directed towards ensuring the preservation of its genetic reserves by keeping its sperm. Using antioxidants in semen extender is one of the ways to reduce the detrimental effects of freezing process on post-thawed quality of spermatozoa.

Review of Postoperative Delirium in Geriatric Patients After Hip Fracture Treatment.

Introduction: Postoperative delirium (POD) is a serious complication occurring in 4-53.3% of geriatric patients undergoing surgeries for hip fracture. Incidence of hip fractures is projected to grow 11.

Diagnostic value of Ultrasonography in the detection of Bone Erosions in patients with Rheumatoid Arthritis: a comparison with Conventional Radiography.

Objective: Rheumatoid arthritis (AR) is the most common systemic inflammatory disease of joints, with prevalence of 1% worldwide. Bone erosion (BE) is a central feature of rheumatoid arthritis and is associated with disease severity and poor functional outcome. Conventional Radiography (CR) and Ultrasonography (US) play an important role in the diagnosis of RA.
