Background: During early development, environmental compounds can induce adult onset diseases and disrupt the circulating vitamin D (VitD) levels. Aim: This study aimed to examine the protective role of VitD against the adverse effects of BPA on male and female mice. Methods: A total of 60 male and female Swiss Albino mice (3 weeks old) were randomly divided into 5 groups; each consisted of 12 mice (6 males and 6 females) and was treated as follows: Group I received no treatment (sham control); Group II, sterile corn oil only (vehicle control); Group III, BPA (400 μg/kg); Group IV, VitD (2,195 IU/kg); and Group V, BPA + VitD. At 10.5 weeks, the animals were sacrificed to conduct histological examinations. Results: BPA-exposed mice were found to have neurobehavioral abnormalities, heart, kidney, and lung diseases with increased apoptotic indices in both sexes. On the other hand, the treatment of BPA mice with VitD altered this scenario with modulated motor activity, enhanced body and organ weights, and preserved the heart, kidney, and lung architecture, alongside a decreased percent apoptotic index. Conclusion: Our findings illustrate that VitD protects mice against BPA-induced heart, kidney, and lung abnormalities. arabic 20 English 103

Aim– This paper aims to review the existing literature relevant to the subject of ISO/IEC 17025 within Arabic countries and Libyan Research Centres Laboratories (LRCL), especially to the Critical Success Factors (CSFs) that effect the implementation of ISO/IEC 17025 standards. Therefore, a review of the literature revealed a major gap in studies in this area of quality standards for testing and calibration laboratories. Methodology– The aspects listed were based on a review of the literature. This paper summaries the key findings result within LRCL using SWOT and Template analysis to analyse the data collected from existing literature and LRCL data. Findings –The findings revealed that despite some organisations have faced challenges undertaking ISO/IEC 17025 implementations, many others have enjoyed the benefits that the systems have brought to the organisations. Outcomes of the research are important for Arabic and Libyan organisations implementing ISO/IEC 17025 systems and for consulting companies assisting with ISO/IEC 17025 implementation. The distribution of the current study results will lead to knowledge transfer and help organisations, among Arabic and developing countries including Libya, in the process of achieving standardisation. Originality, Value – The novelty of this research paper stems from the realisation of critical factors determining a successful implementation of ISO/IEC 17025 within research centers and Laboratories in Arabic countries and LRCL. The originality and value of this research paper is to fill the gap in knowledge in this area, which is explicit to the Arabic countries and Libya in particular. In addition, it contributes to the literature and professional practice by offering new insights into the CSFs for the implementation of ISO/IEC 17025 in Arabic countries and LRCL.

GLUT4 translocation in response to insulin involves the PI3K/Akt pathway and IR mediated phosphorylation of CAP (SORBS1), and formation of the CAP:Cbl. These pathways act in a coordinated manner to regulate glucose, lipid and protein metabolism. In previous studies, T228A polymorphism of SORBS1 gene has been shown to be a protective factor for obesity, type-2 diabetes mellitus (T2DM), polycystic ovary (PCOs), and lacunars infarction. Objectives: The objective of this study was to investigate the association between this polymorphism and T2DM, gestational diabetes (GDM), and obesity. Methods: Genotyping was achieved by PCR-RELP in 227 individuals chosen randomly from the out patient’s clinics of Al-Jala maternity hospital of Tripoli and Gharian hospital, including: 63 T2DM patients, 59 GDM patients, 57 obese, 47 healthy control individuals from Libyan pregnant women population (North-West Region). Results: The results revealed that this polymorphism has no association with T2DM, GDM, and obesity in comparison with the control sample. Conclusion: T228A polymorphism of SORBS1 gene is not associated with the pathological conditions studied. arabic 15 English 98
