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.

Radiation sensor based on a 1D-periodic structure infiltrated by (B-co-MP) a conjugated copolymer.

In this study, a novel gamma-ray radiation sensor has been developed depending on a 1D photonic crystal (1D-PhC). Based on porous silicon (PSi) layer that has been penetrated by a conjugated copolymer (B-co-MP) which consists of BEHP-PPV and MEH-PPV, with a fractional ratio of 60:40. The suggested method for the development of the dosimeter is based on the shift of photonic band-gap to shorter wavelengths, where exposure to gamma-ray radiation at doses ranging from 0 to 20 kGy alters the refractive index of the (B-co-MP) copolymer.
