- Description:
- Autonomic nervous system (ANS) disorders are common in multiple sclerosis (MS). Previous studies showed differences in insulin resistance (IR) and lipoprotein levels in MS subjects compared to controls. Lipolysis caused by increased sympathetic activity could be one of the possible linking mechanisms leading to dyslipidemia in MS. Our study aimed to evaluate ANS activity in the context of glucose and lipid metabolism in people with MS. We prospectively measured short-term heart rate variability (HRV), fasting lipoprotein concentrations, and calculated IR indices based on plasma glucose and insulin levels during oral glucose tolerance test (oGTT) in 32 patients with MS and 29 healthy controls matched for age, sex and body mass index in our study. There was no significant difference in HRV parameters and lipoprotein levels between MS and controls. A significant positive correlation was found between low/high-frequency power ratio (LF/HF) and triglycerides (r=0.413, p=0.021) in MS subjects but not in controls. A significantly lower whole-body insulin sensitivity index (ISIMat) was found in patients with MS compared to the control group (7.3±3.7 vs. 9.8±5.6, p=0.041). No significant correlations were found between LF/HF and IR parameters. In MS subjects, the positive correlation of LF/HF with triglycerides could reflect the effects of sympathetic activity on lipolysis. Positive correlations of sympathetic activity with increased lipoprotein levels could rather reflect processes associated with immune system activation/inflammation, than processes involved in glucose homeostasis maintenance.

- Subject:
- Arduino, watering, soil moisture sensor, zalévání, and senzor půdní vlhkosti
- Language:
- Czech
- Description:
- The aim of our project was to build an autonomous system, the main purpose of which is the care of garden plants, using mostly commercially available open source hardware. Nowadays, many shops offer simple watering systems, but often these are only pumps that periodically switch on and off at an adjustable time. We have built our system on a slightly different basis. It irrigates only when it is necessary. The main components of the system are therefore, in addition to pumps, soil moisture sensors. and Cílem našeho projektu bylo postavit autonomní systém, jehož hlavním účelem je péče o zahradní rostlinstvo, a to s využitím převážně běžně dostupného open source hardwaru. V dnešní době mnohé obchody nabízejí jednoduché zavlažovací systémy, ale často se jedná pouze o čerpadla, která se v nastavitelném čase periodicky spínají. Náš systém jsme vybudovali na trochu jiném základě. Zaléváme pouze tehdy, když je to třeba. Jedny z hlavních komponent systému proto tvoří, kromě čerpadel, také senzory půdní vlhkosti.

- Description:
- Objectives. This study aims to expand previous research findings by focusing on the mechanism of the frustration and satisfaction of basic psy-chological needs that links parental psychologi-cal control and autonomy support to the drive for thinness as an indicator of disordered eating among early adolescent boys and girls in Slo-vakia. Participants and setting. 443 pupils (47.6% girls) reported on the explored variables in a cross-sectional data collection. Hypotheses. The drive for thinness was hypoth-esised to be (1) negatively associated with the satisfaction of basic psychological needs and (2) positively associated with the frustration of basic psychological needs. Autonomy support from the mother (3) and father (4) was hypoth-esised to be positively related to basic psycho-logical needs satisfaction. Psychological control from the mother (5) and father (6) was hypothe-sised to be positively linked to basic psychologi-cal needs frustration. Autonomy support from the mother (7) and father (8) and psychological control from the mother (9) and father (10) were also hypothesised to be indirectly associated with the drive for thinness. Statistical analysis. Structural equation model-ling was carried out and the model was found to be statistically equivalent for boys and girls.Results. The psychological control from the mother was significantly associated with the frustration of basic psychological needs, which was subsequently associated with the drive for thinness. Autonomy support from the mother and father significantly positively explained the satisfaction of basic psychological needs. Limitations. The mediation model was tested using a cross-sectional design. However, the temporal ordering of the examined variables is clear. Furthermore, while the used measures are standardized and widely used abroad, their vali-dation in the population of Slovak adolescents is needed. Other inaccuracies could have been caused by the exclusion of the part of the sample from the analyses and the self-reporting nature of the data. and Cieľ.Táto štúdia presahuje zistenia predošlých výskumov zameraním sa na mechanizmus frustrácie a naplnenia základných psychologic-kých potrieb, ktorý spája rodičovskú psycholo-gickú kontrolu a podporu autonómie s túžbou po štíhlosti, ktorá je indikátorom dysfunkčného stravovania u chlapcov a dievčat v ranej adoles-cencii.Súbor a výskumný dizajn. 443 žiakov (47,6 % dievčatá) zo Slovenska poskytlo informácie ohľadne skúmaných premenných pomocou prierezového zberu dát. Hypotézy. Na základe aktuálneho stavu poznania autori predpokladali, že túžba po štíhlosti bude (1) negatívne asociovaná s naplnením zák-ladných psychologických potrieb a (2) pozitívne asociovaná s frustráciou základných psycholo-gických potrieb. Ďalej predpokladali, že podpo-ra autonómie (3) zo strany matky a (4) otca bude pozitívne asociovaná s naplnením základných psychologických potrieb. Tiež sa predpoklada-lo, že psychologická kontrola (5) matky a (6) otca bude pozitívne asociovaná s frustráciou zá-kladných psychologických potrieb. Napokon sa očakávalo, že podpora autonómie (7) zo strany matky a (8) otca a psychologická kontrola (9) zo strany matky a (10) otca budú v nepriamom vzťahu s túžbou po štíhlosti. Štatistické analýzy. Bolo realizované modelova-nie pomocou štrukturálnych rovníc a model bol štatisticky ekvivalentný pre chlapcov aj dievča-tá. Výsledky. Psychologická kontrola matky bola signifikantne asociovaná s frustráciou základ-ných psychologických potrieb, ktorá bola ná-sledne asociovaná s túžbou po štíhlosti. Podpora autonómie zo strany matky aj otca vysvetľovala naplnenie základných psychologických potrieb.Limity. Po prvé, mediačný model bol testovaný použitím prierezového dizajnu. Avšak časové usporiadanie skúmaných premenných je zrejmé. Po druhé, hoci sú používané metodiky štandar-dizované a široko používané v zahraničí, je po-trebná ich validácia aj v populácii slovenských adolescentov. Napokon nepresnosti mohli byť spôsobené aj vylúčením časti vzorky z analýz a seba posudzujúcim charakterom údajov.

- Language:

- Description:
- We present data supporting the hypothesis that the lysosomalautophagy pathway is involved in the degradation of intracellular triacylglycerols in the liver. In primary hepatocytes cultivated in the absence of exogenous fatty acids (FFA), both inhibition of autophagy flux (asparagine) or lysosomal activity (chloroquine) decreased secretion of VLDL (very low density lipoproteins) and formation of FFA oxidative products while the stimulation of autophagy by rapamycine increased some of these parameters. Effect of rapamycine was completely abolished by inactivation of lysosomes. Similarly, when autophagic activity was influenced by cultivating the hepatocytes in “starving” (amino-acid poor medium) or “fed” (serum-supplemented medium) conditions, VLDL secretion and FFA oxidation mirrored the changes in autophagy being higher in starvation and lower in fed state. Autophagy inhibition as well as lysosomal inactivation depressed FFA and DAG (diacylglycerol) formation in liver slices in vitro. In vivo, intensity of lysosomal lipid degradation depends on the formation of autophagolysosomes, i.e. structures bringing the substrate for degradation and lysosomal enzymes into contact. We demonstrated that lysosomal lipase (LAL) activity in liver autophagolysosomal fraction was up-regulated in fasting and down-regulated in fed state together with the increased translocation of LAL and LAMP2 proteins from lysosomal pool to this fraction. Changes in autophagy intensity (LC3-II/LC3-I ratio) followed a similar pattern., V. Škop ... [et al.]., and Obsahuje seznam literatury
