In NPC patients, previous research has studied the association between X-ray repair cross-complementing group 1 and 3 (XRCC1 and XRCC3) polymorphisms and radio-therapeutic response. The objective of our study was to test the association between XRCC1 Arg399Gln and XRCC3 Thr241Met polymorphisms and the response to radiotherapy in the NPC Moroccan population.

The aim of this study was to evaluate the promoter mutational status of VEGFA and the expression levels of VEGFA, VEGFR1, and VEGFR2 in bladder cancer (BC) tissues and to correlate the results with the clinical-pathological parameters of BC patients. A total of 70 BC patients were recruited at the Urology Department of the Mohammed V Military Training Hospital in Rabat, Morocco.

Impact evidence of the vitamin D status in hypertensive patients in Morocco.

Vitamin D deficiency is a hot topic as it affects about 50% of the world's population. Beyond its extra-osseous effects, notably on the cardiovascular system. In recent years many epidemiological studies have looked at the role of vitamin D status in modulating blood pressure.

Human papilloma virus profiles in breast cancer in correlation with Vitamin D.

The major roles of vitamin D in the genesis of breast cancer and as an immunomodulator against acute and chronic infections have been the subject of much research in recent years. A low vitamin D status could decrease the function of blocking the cell multiplication cycle of the cancer process and weaken the immune system. In this context, we were interested in the implication of vitamin D status in women with human papilloma virus (HPV)-induced breast cancer.

Anthropometry-Based Prediction Equation of Body Composition in a Population Aged 12-88 Years.

Indispensable Amino Acid Digestibility of Moroccan Fava Bean Using the Dual Isotope Method in Healthy Adults.

Background: Assessment of protein quality is necessary to satisfy the nutritional needs of populations across the world. In addition to indispensable amino acid (IAAs) composition, protein digestibility is a major component of IAA bioavailability, playing a crucial role in human health and affecting the linear growth of children.

Objectives: This study aimed to evaluate IAA digestibility of fava beans, a legume widely consumed in Morocco using the dual-tracer method.

In-Silico Molecular Modeling Studies to Identify Novel Potential Inhibitors of HPV E6 Protein.

The etiological agent of some anogenital tract cancers is infection with the high-risk human papillomavirus (HPV). Currently, prophylactic vaccines against HPV have been validated, but the presence of drug treatment directed against the infection and its oncogenic effects remain essential. Among the best drug targets, viral oncoprotein E6 has been identified as a key factor in cell immortalization and tumor progression in HPV-positive cells.
