Exploring the cross-cultural validity of attachment theory: a study of Egyptian mother-child dyads using the Strange Situation Procedure.

Given the dearth of literature on attachment theory in the Arab world, this study explores the cross-cultural validity of attachment theory within an Egyptian sample of 60 mother-child dyads through the Strange Situation Procedure (SSP). The study examines the applicability of attachment theory's universality, normativity, and secure base hypotheses, as well as the prevalence and manifestations of insecurity in an Egyptian sample. The findings supported attachment theory's universality, normativity and secure base hypotheses, while simultaneously pointing towards cultural variations in attachment manifestations.

Impact of Probiotics and Prebiotics on Gut Microbiome and Hormonal Regulation.

The gut microbiome plays a crucial role in human health by influencing various physiological functions through complex interactions with the endocrine system. These interactions involve the production of metabolites, signaling molecules, and direct communication with endocrine cells, which modulate hormone secretion and activity. As a result, the microbiome can exert neuroendocrine effects and contribute to metabolic regulation, adiposity, and appetite control.

The benefits of astaxanthin-rich microalgal powder on growth, health, and disease resistance against Fusarium solani in Pacific white shrimp.

In shrimp aquaculture, enhancing health and disease resistance is crucial for sustainable production. This study investigates the pioneering effects of astaxanthin-enriched microalgal powder from Haematococcus pluvialis (HP) on Pacific white shrimp (Litopenaeus vannamei), focusing on growth efficiency, body composition, immune and antioxidant responses, intestinal health, histopathology, gene expression, and resistance against Fusarium solani. Shrimp (initial weight 5.
