The process of sperm production is well understood, but the studies of essential nutritional elements which are necessary for successful spermatogenesis are not deeply studied as yet. Our review focuses on integrating available information of various nutritional elements involved in spermatogenesis, sperm maturation and male reproductive system development, such as Zinc, Selenium, Folate, Vitam...

INTRODUCTION Adolescence is an important period of nutritional vulnerability due to the increased dietary requirements. OBJECTIVE To describe the nutritional status of adolescent cyclist and a group of normoactive controls. METHODS The HELENA Dietary Assessment Tool was used to evaluate the nutritional intake of 20 adolescent cyclists and 17 controls. Total energy intake, resting energy exp...

The links between diet and genomic instability have been under investigation for several decades, and evidence suggests a significant causal or preventive role for various dietary factors. This study investigates the influence of macronutrients (calories, protein, and glucides) and micronutrients, such as vitamins and minerals, as assessed by a food frequency questionnaire, on genotoxicity biom...

Fertilization with macronutrients, e.g., nitrogen (N) and phosphorus (P), has wide-ranging well-characterized effects on terrestrial ecosystem functions. In contrast, influences of other elements, sodium (Na), calcium (Ca), potassium (K), hereafter, ‘micronutrients’, are poorly understood. To determine micronutrients, their interactions soil carbon (C) cycling, we conducted a full factorial exp...

OBJECTIVE To investigate whether daily dietary fiber intake at the reference level has any impact on studied hormones in a population of Thai women. MATERIAL AND METHOD Twenty-eight healthy Thai women (aged 18-20 years, BMI 18.5-25 kg/m2) with a history of regular menstrual cycles committed themselves to prepared food without changing the usual ratio of three major macronutrients. Dietary fib...

Many bacteria possess cell density-dependent quorum-sensing (QS) systems that often regulate cooperative secretions involved in host-microbe or microbe-microbe interactions. These secretions, or "public goods," are frequently coregulated by stress and starvation responses. Here we provide a physiological rationale for such regulatory complexity in the opportunistic pathogen Pseudomonas aerugino...
