Opis:
Cadmium (Cd) stress significantly affects plant growth and development. Potentilla sericea is typically grown in gardens or as ground cover. In this study, the Cd response of P. sericea was analyzed based on physiological examinations and transcriptome analyses that uncovered the gene expression changes in P. sericea roots induced by a 7-day treatment with 90 μmol/L Cd2+. A total of 53,225 unigenes were identified, including 11,684 differentially expressed genes (DEGs; 8,083 upregulated and 3,601 downregulated). Additionally, 44 gene ontology terms and 127 Kyoto Encyclopedia of Genes and Genomes pathways were significantly enriched among these DEGs. Genes related to glutathione metabolism, plant hormone signal transduction, peroxisome processes, sulfur metabolism, and flavonoid biosynthesis pathways were confirmed as relevant to the Cd response of P. sericea. The molecular biology-related data described here may be useful for the future breeding of transgenic P. sericea plants with increased resistance to heavy metal stresses.

Introduction and objective. Metabolic disorders are associated with a number of negative health consequences. Therefore, the aim of this review was to define the relationships between overweight and obesity, lipid metabolism disorders, hypertension, disorders of carbohydrate metabolism, and cognitive functions. Abbreviated description of the state of knowledge. Metabolic disorders may be linked to the reduction of cognitive functions, such as memory, abstract reasoning, verbal fluency, attention and psychomotor speed. Obesity may lead to changes in the hippocampus, one of the main structures involved in learning and memory. The evidence reviewed suggests that obesity, by inducing inflammation, leads to the dysfunction of brain structures such as the frontal cortex and corpus callosum involved in plasticity processes and cognitive functions. In addition, obesity has been found to be associated with abnormalities in the white matter and glial cells in the brain, which may also cause reduction in processing speed. It is possible that there is a non-linear relationship between lipids and cognitive function moderated by age and the pro- inflammatory process. Disturbances in carbohydrate metabolism can also lead to cognitive impairment, such as: memory, verbal fluency or abstract reasoning. Conclusions. Metabolic disorders are associated with a higher risk of developing cognitive impairment. This association can be moderated by additional factors: lifestyle, oxidative stress, pro-inflammatory processes, genetic factors, age and education.

Opis:
Sclerostin, which is a glycoprotein produced by osteocytes, reduces the formation of bones by inhibiting the Wnt signal pathway. Thyroid hormones are related with Wnt signal pathway and it has been reported that increased thyroid hormones in hyperthyroidism fasten epiphysis maturation in childhood, and increase the risk of bone fractures by stimulating the bone loss in adults. The aim of this study was to examine the sclerostin serum levels, the relation between sclerostin and thyroid hormones as well as the biochemical markers of the bone metabolism in patients with hyperthyroidism (including multinodular goiter and Graves' disease), whose treatments have not started yet. No difference was found in the serum sclerostin levels between the hyperthyroidism group (n=24) and the control group (n=24) (p=0.452). The serum osteocalcin levels and 24-hour urinary phosphorus excretion were found to be higher in the hyperthyroid group than in the control group (p<0.001, p=0.009). A positive correlation was determined between the sclerostin and bone alkaline phosphatase levels (p<0.001); a negative correlation between the osteocalcin and thyroid stimulating hormone (TSH) (p<0.05); a positive correlation between the osteocalcin and thyroid hormones (FT3,FT4) (p<0.001); and a positive correlation between the deoxypyridinoline and hydroxyproline (p<0.001). No correlation was determined between sclerostin and TSH,FT3,FT4 (p>0.05). Therefore, we consider that a long-term study that covers the pre-post treatment stages of hyperthyroidism, including both the destruction and construction of the skeleton would be more enlightening. Moreover, the assessment of the synthesis of sclerostin in the bone tissue and in the serum level might show differences.

Opis:
Fatty acids (FAs) are one the most essential substances in intrauterine human growth. They are involved in a number of energetic and metabolic processes, including the growth of cell membranes, the retina and the nervous system. Fatty acid deficiency and disruptions in the maternal-placental fetal metabolism of FAs lead to malnutrition of the fetus, hypotrophy and preterm birth. What is more, metabolic diseases and cardiovascular conditions may appear later in life. Meeting a fetus' need for FAs is dependent on maternal diet and on the efficiency of the placenta in transporting FAs to fetal circulation. "Essential fatty acids" are among the most important FAs during the intrauterine growth period. These are α-linolenic acid, which is a precursor of the n-3 series, linoleic acid, which is a precursor of the n-6 series and their derivatives, represented by docosahexaenoic acid and arachidonic acid. The latest studies have shown that medium-chain fatty acids also play a significant role in maternal-fetal metabolism. These FAs have significant effect on the transformation of the precursors into DHA, which may contribute to a relatively stable supply of DHA - even in pregnant women whose diet is low in FAs. The review discusses the problem of fatty acid metabolism at the intersection between a pregnant woman and her child with reference to physiological pregnancy, giving birth to a healthy child, intrauterine growth restriction, preterm birth and giving birth to a small for gestational age child.

This study compared the ability of daidzein, a soy isoflavone, with that of 17β-estradiol to prevent bone loss in cadmium (Cd)-exposed ovariectomized (OVX) rats during growth. Four week-old female Wistar rats were randomly assigned to five treatment groups of 9 rats each, either (1) sham-operated (SH); (2) OVX and placed on experimental diets (OVX); (3) OVX fed 50 ppm of CdCl2 (OVX-Cd); (4) OVX fed 50 ppm of CdCl2 and 10 µg of daidzein per kg of body mass (OVX-CD-D); or (5) OVX fed 50 ppm of CdCl2 and 10 µg of estrogen per kg of body mass (OVX-CD-E). All rats were given free access to AIN-76 modified diet and drinking water, with or without Cd, for 8 weeks. The OVX groups gained more (P < 0.05) body mass than the SH group. Femoral mass was increased by feeding daidzein and estradiol, whereas femoral length was not (P > 0.05) significantly different among groups. Femoral breaking force was not significantly different among groups, however, femoral BMD was significantly lower in OVX-Cd than in the SH and OVX groups. Morphologically proliferative cartilage and hypertrophic cells in femur showed normal distribution in OVX-Cd-D and OVX-Cd-E groups unlike those in OVX-Cd group. These findings suggest that Cd-OVX-induced osteopenia or osteoporosis probably results from an increase in bone turnover.

Opis:
Introduction. Positron Emission Tomography (PET) is a non-invasive diagnostic tool that provides tomographic images and measures quantitative parameters of cell viability and metabolic activity of tissues. The most important used tracer in PET is an 18-F-Fluorodeoxy-glucose (FDG), the glucose molecule of which is labeled with a radiotracer and allows measurement and mapping of tissue glucose uptake. There are many studies in PET/CT which rely on some mammalian species, and recently on fish. Objective. The aim of this survey by using FDG-PET/CT are to optimize and determine FDG uptake in fish, in this case, common carp (Cyprinus carpio) using three treatments: Basic fish meal, Vita Pulvis and Probiotics s with two replications were used. Sphere Volume of interest (VOI) were drawn hand for the all organs, and standard uptake value (SUV) means were calculated. Results. The SUV mean for glucose uptake in the liver and gastrointestinal tract of fish were more similar to those of humans than rats or mice. SUV mean in fish fed by Probiotics ss in the major organ were less than those fed by Vita Pulvis and basic fish meal. The results present the opportunity to focus on studies of metabolism and screening for the effects of nutrients on body development.

Opis:
Insulin resistance (IR) plays a critical role in metabolic syndrome (MS). Previous studies have demonstrated that activated ROCK is increased in MS patients. However, the effect of Rho-kinase (ROCK) on IR has not been definitely determined. Thus, the aims of the present study were to determine whether ROCK activation induces IR or affects myocardial structure and function, as well as the possible mechanisms underlying this process. Wistar rats fed high fat, high glucose and high salt diet sewed as model of MS and we used transmission electron microscopy, echocardiogram technology, and terminal deoxynucleotidyl transferase-mediated DNA nick-end labeling staining to identify any myocardial damage. The protein levels of MYPT-1 (characteristic of ROCK activation), IRS-1 and AKT were analyzed by immunohistochemistry and Western blotting. In hearts from MS rats, we found increased protein levels of phospho-MYPT-1 and phospho-IRS-1 (Ser307) and decreased phospho-AKT compared to levels in normal rats. In conclusion, the results suggest that ROCK-mediated IR is involved in the development of myocardial impairments in MS rats and that this effect is mediated probably via the IRS-1/PI3-kinase/AKT pathway.

Przeszło 30 lat temu zaobserwowano, iż Eskimosi, których dieta opiera się na tłustych rybach morskich, rzadko chorują na choroby układu krążenia takie jak choroba niedokrwienna serca, zawał mięśnia sercowego. Obserwacje te dały początek licznym badaniom epidemiologicznym, klinicznym i doświadczalnym mającym na celu wyjaśnienie tego zjawiska. Obecnie nie ulega wątpliwości, iż ryby będące źródłem niezbędnych nienasyconych kwasów tłuszczowych z grupy n-3 (n-3 PUFA) są ważnym składnikiem pożywienia, gdyż zawarte w nich kwasy tłuszczowe istotnie wpływają na szereg przemian metabolicznych i tym samym na ryzyko rozwoju różnych chorób.
Fatty acids derived from fish and fish oils have a strong beneficial effect on cardiovascular health and neurodevelopment. Dietary omega 3 fatty acids prevent cardiovascular disease development by the influence on eicosanoid synthesis, cytokine and growth factors production, lipid and lipoprotein metabolism, endothelial relaxation. They have a strong antiarrhytmic action on the heart. Enhanced consumption of fish derived fatty acids is related to the low incidence of cardiovascular events and sudden cardiac deaths. High content of mercury in some fishes may attenuate the beneficial effects of omega 3 fatty acids on cardiovascular health and also on neurodevelopment of newborns and children

Opis:
Nutrition is a factor of major importance for health and also for development of diet related disorders. Nowadays there is no doubts that interaction between genes and nutrition plays a key role in health risk prediction and disease prevention. Individual nutritional status is determined not only by food availability but also by genes that control food intake, nutrient absorption and metabolism. On the other hand nutrients can significantly influence different genes expression and metabolic processes. Knowledge of genetic susceptibility to disease will help identify people at enhance risk and their response to diet. The prevalence of the types of genes of interest may differ between populations. The same genotype does not confer the same risk in all populations because of differences in environmental factors and nutritional habits. Therefore, populations should not simply copy each other’s dietary recommendations. Based on genetic and nutritional studies the best way for expression of healthier phenotypes should be found and used to promote health and prevent different diseases development.

Background. The physical activity of 29 football players using either aerobic or anaerobic energy regimes was tested during official games and in the laboratory. Material and methods. Under conditions of gradually increasing power on a treadmill, maximal running speed (V, km/h), oxygen consumption (VO2, mL/min/kg), heart rate (HR, beats/min), and anaerobic metabolism threshold (AT mL/min/kg) were determined, and blood lactate (BLact, mmol/L) was measured. Results. The correlation between the total length of distance run during the game and treadmill running speed for the outcome measures were as follows: anaerobic metabolism threshold, r=0.54 (p=0.032), BLact, r=0.37 (p=0.034), VO2max, r=0.41 (p=0.027), and HR, r=0.36 (p=0.047). We found aerobic mechanisms were dominant in ensuring the game activity of football players. Specifically, aerobic mechanisms contribute roughly 32.4-43.8% to playing activity, while aerobic-anaerobic energy supply mechanisms provide for only 17%. Lactic and alactic mechanisms provide for 5.6% and 1.6%, respectively. Conclusions. The results provide valuable information on the relationship between football play activity and aerobic and anaerobic energy supply mechanisms. Enhancing the functionality of the anaerobic lactic-alactic energy system can lead to growth and improvements in physical performance in football players.

Opis:
Resting cyst formation is a crucial process of cryptobiosis in protists. In colpodid ciliates, cyst formation is accompanied by large-scale morphological changes such as changes of cell shape, resorption of cilia, and formation of a cyst wall; additionally, the cell cycle is arrested. These changes provide acquired tolerance against environmental stresses. During cyst formation, mitochondrial membrane potential is reduced and the level of the ATP synthase beta chain is suppressed, strongly indicating that metabolism has ceased. Here, however, we show that ATP levels are elevated during the initial phases of encystment implying that metabolism may not be completely suppressed. This finding suggests another aspect of resting cyst formation that is not applicable to cryptobiosis.
