Genetic Assessment and Positioning of Algerian Barley Landraces with Respect to Landraces from the Middle East and Europe Using RAPD and SSR Markers.

Landraces are a critical genetic resource for resilience breeding, offering solutions to prepare agriculture for the challenges posed by climate change. Their efficient utilisation depends on understanding their history and genetic relationships. The current study investigates the phylogenetic relationships of barley landraces from Algeria, varieties from the Near and Middle East, traditional landraces, and modern cultivars from Europe.

Impact of COVID-19 Lockdown on Children's Health in North Africa.

Objectives: Lockdown measures have been adopted in many countries around the world to control the spread of COVID-19. These measures induced long confinement period that may have had an unintended negative impact on children's life behaviors and health. This study aimed to investigate the impact of behaviors related to COVID-19 confinement on body weight/BMI changes in children from Constantine, Algeria.

Effect of Spermatic Nuclear Quality on Live Birth Rates in Intracytoplasmic Sperm Injection.

Background: Our study defines the clinical role of sperm DNA damage in the assisted reproductive technology procedure.

Aim: To investigate if the compaction of chromatin explored added to the analysis of the sperm DNA fragmentation allows obtaining a new indicator for sperm genome quality linked to live birth rate (LBR).

Design: This was a prospective study, undergoing 101 cycles in the intracytoplasmic sperm injection (ICSI) program.

Metabolic syndrome, leptin-insulin resistance and uric acid: a trinomial foe for Algerian city-dweller adolescents' health.

Background Adolescence is one of the critical periods where increased risk for long-term obesity-related complications is an important health concern. This highlights the need to perform early diagnostics based on precise biomarkers to decrease the risk of complications in adolescents with obesity. Objective To determine the relationships between serum levels of uric acid (UA), leptin and insulin with metabolic syndrome (MS) components in Algerian adolescents.

Relationships between metabolic profile, hypertension and uric acid with cardiometabolic risk in adolescents with abdominal obesity: impact of geodemographic factors on the prevalence of abdominal obesity.

Background Association of hyperuricemia, dyslipidemia and high blood pressure (BP) among adolescents with high waist-to-height ratio (WHtR) remains not fully addressed and could represent a new way to diagnose adolescents early with cardiometabolic risk. Objective We aimed to determine abdominal obesity (AO) prevalence and investigate relations between AO, uric acid (UA), lipid profiles, BP and geographical patterns in adolescents. Subjects 577 and 204 Algerian students aged between 10 and 19 years were included in our epidemiological and biochemical studies, respectively.

Oral Fat Sensing and CD36 Gene Polymorphism in Algerian Lean and Obese Teenagers.

Growing number of evidences have suggested that oral fat sensing, mediated by a glycoprotein CD36 (cluster of differentiation 36), plays a significant role in the development of obesity. Indeed, a decreased expression of CD36 in some obese subjects is associated with high dietary fat intake. In the present study, we examined whether an increase in body mass index (BMI) is associated with altered oleic acid lingual detection thresholds and blood lipid profile in young Algerian teenagers (n = 165).

Mutations of the aurora kinase C gene causing macrozoospermia are the most frequent genetic cause of male infertility in Algerian men.

Klinefelter syndrome and Y-chromosomal microdeletion analyses were once the only two genetic tests offered to infertile men. Analyses of aurora kinase C (AURKC) and DPY19L2 are now recommended for patients presenting macrozoospermia and globozoospermia, respectively, two rare forms of teratozoospermia particularly frequent among North African men. We carried out genetic analyses on Algerian patients, to evaluate the prevalence of these syndromes in this population and to compare it with the expected frequency of Klinefelter syndrome and Y-microdeletions.
