1(12.3)AU] exercise and returned to baseline by 24 hr. For the control condition, EI was different between pre [24.8(10.2)AU] and 48 hr [21.5(10.7)AU]. The change in EI in the experimental condition was greater than the control condition immediately post (p = .039) and at 48 hr (p = .016). For ISO, there was an interaction (p  less then  .001). In the experimental condition ISO decreased from pre [40.6(14.7)Nm)] to post [24.8(9.4)Nm] and remained depressed. CONCLUSIONS Exercise produced a swelling response, which was elevated 48 hr post. Despite a sustained increase in MT, EI was only elevated immediately post exercise. This article is protected by copyright.

Here, following a variational principle, I try to explore how slight changes in the buildup of cells reveal critical features of life's physics. In a first section, I suggest that we use stable isotopes of the atoms of life to see how living cells fare, beginning with life in heavy water. Subsequently, isotopes of the other main biogenic atoms are suggested as an extension of the variational principle, despite their likely very small influence on the course of biological activity. Finally, two atoms of the second row of Mendeleev's table, boron and fluorine are explored as a further extension of the principle. Phospho(enol)pyruvic acid monopotassium cell line The use of the former is still in its infancy, whereas the latter, based on existing fluorinases, could open the door to a more general use of halogens in synthetic biology. © 2020 Wiley-VCH Verlag GmbH & Co.

Most studies were performed in westernized countries, but only few studies in developing nations. Therefore, we aimed to study the perception on management of constipation among Thai pediatricians. METHODS We performed a national survey using an online 37-item questionnaire that included demographics, perception and practice on constipation in children. We used a 5-point scale to determine perception in each aspect (5 as strongly agreed and 1 as strongly disagreed). RESULTS We received 275 responses (response rate of 11.0%), most were female (69.1%), subspecialists (55.6%) and worked in the government-based setting (69.5%). We noted that only 51.8% considered disimpaction if physical examination is suggestive of fecal impaction. Most pediatricians used lactulose for both disimpaction and maintenance phases (83.4 and 91.9%, respectively); however, pediatricians perceived that the caregivers of constipated children were concerned about tolerance or dependence of most commonly used laxatives, ranged from 45.8 to 63.8%. We also found that recently graduated pediatricians were more likely to provide advice on fluid intake, toilet training, and laxative use, as well as consider polyethylene glycol for disimpaction than the older individuals (P = .003, .02, .004, and .02, respectively). CONCLUSIONS The proportion of pediatricians who consider disimpaction remained suboptimal. Providing appropriate knowledge on the pharmacologic management, especially disimpaction and issues on laxatives, may be helpful for pediatricians and caregivers. The education may also need to be tailored to various pediatricians' experience and work settings. This article is protected by copyright.

In recent years, great efforts have been directed towards understanding how its nanoscale structure affects activity and selectivity for the electrochemical CO2 reduction reaction (CO2RR). Furthermore, many attempts have been directed to improve these two properties. Nevertheless, to advance towards applied systems, the stability of the catalysts during electrolysis is of great significance. This aspect, however, remains less investigated and discussed across the CO2RR literature. In this mini-review, the recent progress on understanding the stability of copper-based catalysts is summarized, along with the very few proposed degradation mechanisms. Finally, our perspective on the topic is given. © 2020 WILEY-VCH Verlag GmbH & Co.

Peroxisome proliferator-activated receptor (PPAR)γ is a member of the nuclear receptor superfamily that regulates the expression of placental 11β-HSD2. Nuclear factor kappa B (NF-κB) is a transcription factor that regulates inflammatory signaling. This study aimed to investigate the association among 11β-HSD2, PPARγ and NF-κB p65 in small for gestational age (SGA) infants. METHOD OF STUDY Forty-six SGA and 46 appropriate for gestational age (AGA) infants were enrolled for this study. Both newborns and placentas were weighted. Placental 11β-HSD2 levels were measured using Western blotting. Placental PPARγ and NF-κB p65 were detected by immunohistochemistry. Placental inflammatory cytokines were evaluated by real-time RT-PCR. RESULTS 11β-HSD2 levels were lower in SGA placentas than those of AGA placentas. Placental PPARγ-positive nuclei were less in SGA than those of AGA. By contrast, placental NF-κB p65-positive nuclei were more in SGA than those of AGA. The levels of CRP, TNFα, IL-8 and IL-1β, several inflammatory cytokines, were higher in SGA placentas. Correlation analysis showed that neonatal weight was positively associated with PPARγ and 11β-HSD2 in SGA placentas. By contrast, neonatal weight was inversely correlated with NF-κB p65 in SGA placentas. 11β-HSD2 was positively correlated with PPARγ in SGA placentas. CONCLUSIONS Inflammation-associated downregulation of placental PPARγ and 11β-HSD2 may be involved in SGA. This article is protected by copyright. All rights reserved.
