Globozoospermia is a form of male infertility characterized by spermatozoa with spherical heads lacking acrosomes. The aim of this study was to evaluate ultrastructural and molecular defects in different types of globozoospermia. Semen samples from 12 infertile patients (9 with complete globozoospermia and 3 with partial globozoospermia) and 10 normozoospermic men (control) were examined by transmission electron microscopy and immunocytochemistry with antibodies against lamin B1.

Article Synopsis
- - The study aimed to explore long-term health outcomes in children and young people post-COVID-19, particularly focusing on post-COVID-19 condition (PCC) and incomplete recovery, comparing these outcomes with those from other non-SARS-CoV-2 infections.
- - Conducted in Moscow, researchers followed two cohorts of pediatric patients with confirmed COVID-19 from two different time periods (Wuhan and Omicron variants) and compared them to a reference group of those with other infections but negative for SARS-CoV-2.
- - Findings revealed that the incidence of PCC was significantly higher in the Wuhan variant group compared to the reference group, while the Omicron variant showed no significant difference in PCC outcomes when compared to the
Article Synopsis
- - The European Academy of Allergy and Clinical Immunology (EAACI) is revising their guidelines for diagnosing IgE-mediated food allergies, aiming to consolidate findings from 149 studies involving 24,489 patients published between 2012 and 2021.
- - Systematic reviews and meta-analyses revealed that skin prick tests (SPT) for fresh cow's milk and raw egg showed high sensitivity (90% and 94%), while specific IgE tests for individual food components demonstrated high specificity for various allergens like peanuts and eggs.
- - The basophil activation test (BAT) was found to be highly specific for diagnosing peanut (90%) and sesame (93%) allergies, indicating that while SPT and specific Ig
The aim of this study was to evaluate the effect of antioxidant supplementation in diluted semen from Muscovy drakes after the induction of oxidative stress (OS) on the sperm motility, kinematic parameters and biochemical markers - lipid peroxidation (LPO) levels and total glutathione (tGSH) concentration. The pooled semen was distributed equally into three parts, diluted (1:3 v/v) with IMV Canadyl, HIA-1 or AU, and stored at 4°C for 6 h. Later, the semen was equilibrated at 20-25°C for 15 min, and divided in Eppendorf tubes.
