The Impact of Increased Physical Activity at School on the Nutritional Behavior and BMI of 13-Year-Olds.

: Diet and physical activity (PA) significantly impact health. Unfortunately, a worrying trend of decreasing PA among children and adolescents, accompanied by unhealthy nutritional behavior, is observed worldwide. The aim of the study was to evaluate the nutritional behavior and body mass index (BMI) of adolescents aged 13 years in groups of extended and standard PA at school.

Elevated physical activity at school decreased blood pressure in children aged 10-12 years who were overweight and obese.

Aim: We investigated the effect that increased physical activity (PA) sessions had on the blood pressure of school-aged children who were overweight and obese.

Methods: This Polish pilot, prospective study followed up 148 children from six elementary schools from 10 to 12 years of age. They were divided into two groups, based on parental preferences.

Ethyl glucuronide and ethyl sulfate in the zebrafish after ethanol exposure.

Ethanol exposure during pregnancy is an important problem and is the cause of fetal alcohol syndrome (FAS) and fetal alcohol spectrum disorder (FASD). The etiology of FAS and FASD can be elucidated using animal models. Recently, a novel model, the zebrafish (Danio rerio), has garnered the interest of researchers.

Increased Physical Activity at School Benefits Arterial Blood Pressure in Children-A Prospective Follow-Up Cohort Study.

(1) Background: A sedentary lifestyle and low physical activity (PA) increase the risk of hypertension in children. The aim of this study was to assess the impact of increased PA at school by elevation of the number of compulsory physical education (PE) lessons on arterial blood pressure in children during a two-year follow-up. (2) Methods: Children ( = 245) born in 2007 attending a standard or elevated number of PE lessons in the school timetable (4 and 10 h a week, respectively) took part in the study.

The Impact of Physical Activity at School on Children's Body Mass during 2 Years of Observation.

(1) Background: Children's overweight and obesity are a growing public health problem. The aim of this study was to assess the influence of physical activity (PA) at school on body mass of children aged 10-12 during 2 years of observation. (2) Methods: Primary school children ( = 245, 48% girls and 52% boys) took part in the study.

Hematological and Hematopoietic Effects of Bactericidal Doses of -Cinnamaldehyde and Thyme Oil on Juveniles.

The effects of two potential antibacterial agents of plant origin: -cinnamaldehyde (TC) and thyme oil (TO) on the peripheral blood parameters and cellular composition of hematopoietic tissue of were studied. Both phytochemicals were used in the doses based on the bactericidal concentrations against spp. developed earlier in study.

Food Safety When Eating Out-Perspectives of Young Adult Consumers in Poland and Turkey-A Pilot Study.

Food safety is perceived differently by consumers in different countries. The objective of this study was to examine the experience of young adults regarding the safety of meals eaten outside the home in Poland and Turkey. Questionnaire surveys were conducted on a group of 400 young adults.

Effects of Oxytetracycline and Gentamicin Therapeutic Doses on Hematological, Biochemical and Hematopoietic Parameters in Juveniles.

Hematological, biochemical and hematopoietic effects of therapeutic doses of two antibiotics, oxytetracycline (OTC) and gentamicin (GEN), in clinically healthy common carp juveniles were studied. The fish were divided into four groups: controls 1 and 2 (untreated or injected with 0.6% NaCl solution), and two groups treated with antibiotics (orally with 75 mg/kg OTC four times every two days or injected with a single dose (4 mg/kg) of GEN dissolved in 0.

Eating Behaviour and Physical Fitness in 10-Year-Old Children Attending General Education and Sports Classes.

The aim of this study was to evaluate the body mass index (BMI), selected eating behaviour and physical fitness of children aged 10 years attending general education and sports classes in Siedlce. Subject children were 272 girls and boys mean aged 10.8-years attending general education (GC) and sports classes (SC).

The Nutritional Behaviour of Pregnant Women in Poland.

A woman's diet during pregnancy can significantly affect her health, as well as her child's future development and well-being. Unfortunately, many pregnant women do not follow the recommended nutritional guidelines. The reason could be that they have insufficient knowledge about nutritional best practice.

The effects of Roundup on gametes and early development of common carp (Cyprinus carpio L).

To determine the effects of Roundup, a commercial formulation of glyphosate, gametes, and embryos of common carp (Cyprinus carpio L) was exposed to wide range of herbicide concentrations (0.0, 0.1, 0.

Effect of glyphosate-based herbicide on hematological and hemopoietic parameters in common carp (Cyprinus carpio L).

The effects of Roundup (glyphosate-based herbicide) on peripheral blood parameters and hematopoietic tissue cellular composition and activity in common carp juveniles were evaluated. The fish were exposed for 7 days at 0.0, 0.

The effects of cadmium and copper on embryonic and larval development of ide Leuciscus idus L.

The effects of Cd and Cu on embryos and larvae of the ide Leuciscus idus were evaluated. The ide is an European cyprinid fish, natural populations of which tend to decrease. The ide is also used as a bioindicator organism to evaluate water quality.

The aim of the present study was to evaluate bioaccumulation of metals in various tissues of the freshwater fish Cyprinus carpio L. exposed to cadmium and copper (a xenobiotic and a microelement). The fish were subjected to short-term (3 h, Cd-S and Cu-S) or long-term (4 weeks, Cd-L and Cu-L) exposures to 100 % 96hLC₅₀ or 10 % 96hLC₅₀, respectively.

The effects of heavy metals on embryonic development of fish (a review).

Early developmental stages of fish are particularly sensitive to water pollution. Heavy metals may affect various developmental processes during the embryonic period, which results in a reduction of offspring quantity and quality. Waterborne metals may accumulate in the gonads of spawners and adversely affect gamete production and viability, or exert direct toxic influence upon developing embryos.

Ammonium ionic liquid as modulator of the critical micelle concentration of ammonium surfactant at aqueous solution: conductimetric and dynamic light scattering (DLS) studies.

We report measurements of self aggregation in aqueous solution of an ionic liquid (IL), didecyl-dimethylammonium nitrate ([DDA][NO(3)]) and a surfactant hexadecyl-trimethylammonium bromide (CTAB) and of mixtures of these two salts. The electrical conductivity and dynamic light scattering (DLS) measurements were used for the characterization of the aggregation process. The conductivity measurements were performed at three temperatures.
