Scanning electron microscopy, morphometric and energy dispersive X-Ray analysis of cephalothoracic structures exploring defensive and sensory features in kuruma shrimp (Marsupenaeus japonicus Spence Bate, 1888).

Background: Kuruma shrimp (Marsupenaeus japonicus) is a commercially important crustacean and a valuable global food source. This study employed scanning electron microscopy (SEM) to explore the morphology and morphometric features of the Marsupenaeus japonicus cephalothoracic structures, including antennules, antennas, scaphocerite, rostrums, and eye stalks. The primary focus was on understanding the role of each part, especially through the examination of setae, which are crucial for chemoreception and defense.

Novel Insights Into the Ultrastructural and Immunofluorescence Characteristics of Limb Skin in the Red-Eared Slider Turtle (Trachemys scripta elegans).

The red-eared slider turtle, a species facing environmental challenges and habitat loss, exhibits a complex skin architecture that is crucial for its adaptation and survival. Our study aims to provide a comprehensive characterization of the turtle's skin structure and to elucidate the distribution and localization of its various cellular components, with a focus on understanding the skin's role in adaptation and ecological interactions. To achieve these goals, we employed light microscopy, transmission electron microscopy (TEM), and comprehensive immunofluorescence using 10 specific antibodies.

Analyzing the morphology and avian β-defensins genes (AvβD) expression in the small intestine of Cobb500 broiler chicks fed with sodium butyrate.

Background: Sodium butyrate is a potential antibiotic growth promoter and has had advantageous effects on the poultry industry.

Methods: Evaluating the effect of sodium butyrate on the intestinal villi and the humoral part of innate immunity of the male Cobb 500 broiler using scanning electron microscopy and quantitative real-time PCR analysis, the control group and treated group of Cobb 500 with SB supplemented received water containing 0.98 mg sodium butyrate.

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.
