Characterization of giant endocrine cells in the fundic stomach of African catfish (Clarias gariepinus) demonstrated by histochemical, immunohistochemical and ultrastructure microscopy methods suggesting their role in immunity.

Endocrine cells in the fundic stomach of Clarias gariepinus were characterized in this work using transmission electron microscopy, immunohistochemistry, and histochemistry. Performic acid mixed with alcian blue pH2.5 and silver stain were among the histochemical stains used for endocrine cells.

A new insight for investigating the prenatal and postnatal ossification centers of pelvic and femur bones in white New Zealand rabbits (Oryctolagus cuniculus) using 3D CT, double stain technique, and morphometry.

Background: The ossification centers in rabbit limbs are related to fetal age and bone maturation.

Objective: To address the limited studies on ossification in the hind limbs of New Zealand rabbits, we investigated the prenatal and postnatal development of the pelvic and femur bones.

Methods: Double staining with Alcian Blue and Alizarin Red, computed tomography (CT), and 3D reconstruction were employed to visualize and analyze ossification centers in detail.

Impact of COVID-19 on asthma control in Kirkuk City: an analysis of post-pandemic trends.

Bronchial asthma, a common chronic respiratory disease, should be managed and controlled correctly to prevent symptoms and maintain a good quality of life. Viral upper respiratory infections, especially the widespread COVID-19 virus, can exacerbate asthma. This study investigated the impact of COVID-19 severity (mild, moderate, severe) on asthma control compared to a control group without COVID-19.

Novel Insights Into the Architecture of Macro and Microstructures in Cattle Ossa Cordis.

Ossa cordis, bones located within the heart trigones, are often classified as heterotopic or ectopic bones. Despite their high prevalence in cattle and some other bovids, little is known about their structure or development. Scanning electron microscopy, X-ray microtomography, gross dissections, and measurements showed the anatomical locations, prevalence, shapes, and measurements of the cardiac bones in both Egyptian Baladi cattle and Holstein-Friesians.
