A chronic moderate methionine administration induced hyperhomocysteinemia associated with cardiovascular disease phenotype in the sand rat Psammomys obesus.

Introduction: Cardiovascular diseases were defined as coronary artery, cerebrovascular, or peripheral arterial disease. Hyperhomocysteinemia (Hhcy) is an independent risk factor of cardiovascular diseases, including atherosclerosis. Our previous studies demonstrated the involvement of Hhcy in cardiovascular remodeling in the sand rat Psammomys obesus.

Impact of the Living Donor Age and the Hormonal Profile of Algerian Renal Transplant Recipients.

Kidney transplantation is the best treatment received by an uremic patient. One of the major advantages of transplantation is restoring a hormonal profile as before the chronic kidney disease. However, the posttransplant state depends on several factors including the quality of the graft.

Children hypertension in Northern Africa.

Objectives: To assess factors associated with prehypertension and hypertension among children in North Africa.

Methods: An epidemiological observational, school- and college-based study among 3562 healthy children and adolescents to assess factors associated with blood pressure categories (normal, prehypertensive, hypertensive), including perinatal (gestational age, birth weight, breastfeeding) and current lifestyle characteristics (body mass index, time spent watching a screen and time spent exercising).

Results: Prevalence of hypertension increased with age from 8.

Hyperhomocysteinemia and myocardial remodeling in the sand rat, Psammomys obesus.

Objective: Numerous studies have shown that a methionine-rich diet induces hyperhomocysteinemia (Hhcy), a risk factor for cardiovascular diseases. The objective of the present study was to determine the involvement of Hhcy in cardiac remodeling in the sand rat Psammomys obesus.

Materials And Methods: An experimental Hhcy was induced, in the sand rat Psammomys obesus, by intraperitoneal injection of 300 mg/kg of body weight/day of methionine for 1 month.

The role of homocysteine in seminal vesicles remodeling in rat.

Introduction: Elevated plasma homocysteine (Hcy) levels have been associated with several tissue injuries including heart and liver fibrosis. In these diseases, hyperhomocysteinemia (Hhcy) plays a major role in modulating the alteration of the balance between matrix metalloproteinases (MMP) and tissue inhibitors of metalloproteinases (TIMPs), leading to the pathological accumulation of extracellular matrix (ECM) proteins. Since the effect of Hhcy on ECM of seminal vesicle was not studied, the aim of our research was to check if Hcy can induce a remodeling within seminal vesicles ECM.
