Although most experimentally characterized proteins with similar sequences assume the same folds and perform similar functions, an increasing number of exceptions is emerging. One class of exceptions comprises sequence-similar fold switchers, whose secondary structures shift from α-helix β-strand prediction discrepancies from JPred4 discriminated between the different conformations of sequence-similar fold switchers with high statistical significance (P less then  1.8*10-19 ). Thus, we used these discrepancies as a classifier and found that they can often robustly discriminate between sequence-similar fold switchers and sequence-similar proteins that maintain the same folds (Matthews Correlation Coefficient of 0.82). We found that JPred4 is a more robust predictor of sequence-similar fold switchers because of (a) the curated sequence database it uses to produce multiple sequence alignments and (b) its use of sequence profiles based on Hidden Markov Models. Our results indicate that inconsistencies between JPred4 secondary structure predictions can be used to identify some sequence-similar fold switchers from their sequences alone. Thus, the negative information from inconsistent secondary structure predictions can potentially be leveraged to identify sequence-similar fold switchers from the broad base of genomic sequences.The current work investigated the extent to which children (N=171 6- to 8-year-olds) and adults (N = 94) view punishment as redemptive. In Study 1, children-but not adults-reported that "mean" individuals became "nicer" after one severe form of punishment (incarceration). Moreover, adults expected "nice" individuals' moral character to worsen following punishment; however, we did not find that children expected such a change. Study 2 extended these findings by showing that children view "mean" individuals as becoming "nicer" following both severe (incarceration) and relatively minor (time-out) punishments, suggesting that the pattern of results from Study 1 generalizes across punishment types. Together, these studies indicate that children-but not adults-may view punishment as a vehicle for redemption.Hyperostosis frontalis interna (HFI) represents an abnormality of the frontal cranial bone that is characterized by bilateral, nodular thickening of its inner lamina and may sometimes be associated with neuropsychiatric symptoms such as headaches and depression. The aim was to assess prevalence, sex and age differences of HFI and frontal bone thickness by means of MRI. This retrospective study included 908 subjects who were divided into male and female groups and further subdivided into three groups, youngest (≤45 years), middle-aged (46- 65 years) and the oldest group (65 years). The thickness of the frontal bone was measured on the T2-weighted axial images at the top level of the lateral ventricles as a mean from both sides. We considered 10mm or thicker frontal bone as HFI. The total prevalence of HFI was 8.1%, with a more frequent occurrence in women (p0.05). In males, there was no difference in the frontal bone thickness between different age groups (p0.05), while in females we found differences between the youngest and the oldest group, and also between the middle-aged and the oldest group (p0.05). The female respondents had a thicker frontal bone, which was statistically significant only in the oldest group (p0.001). Frontal bone thickness was age-dependent only in women (Spearman's Rho 0.11; p≤0.01). In women, unlike in men, there is an age-related progression of HFI with increasing prevalence, with 16.4% occurrence in the oldest group.Spatial reference memory in rodents is commonly performed in the Morris Water Maze (MWM). The use of control groups on this task is essential in order to subtract brain activity not related to learning. To study the functional contribution of selected brain areas, we assessed neuronal metabolic activity thorough quantitative cytochrome c oxidase histochemistry. This technique allows the measurement of the oxidative metabolism responsible for ATP production. Our objective is to analyse if the swimming control group is an optimal control for the evaluation of spatial reference memory task. To do so, we explore the behaviour in the MWM and the neuronal metabolic activity of motor cortex and its layers, in addition to hippocampus. For this purpose, three groups of Wistar rats were used reference memory group, swimming control, and cage control. The behavioural results show significant differences between the experimental group and the swimming control group in time spent in the quadrants and swimming speed. In addition, higher neuronal hippocampal metabolic activity (CA1 subfield) was found in the experimental when compared to both controls. However, there are no differences in the motor cortex neuronal metabolic activity of the groups. Therefore, we can assume that the swimming control group effectively isolates the motor activity during the swim and the behavioural results are due to the hippocampal activity related to learning itself and not the physical activity performed in the labyrinth.This study was aimed to examine the effects of caffeic acid phenethyl ester (CAPE) on endothelial dysfunction in rats with exercise-induced oxidative stress. Tests were performed on male (n=32) young adult Sprague-Dawley rats (12 weeks of age). The experimental animals were divided into four groups in equal numbers. Group 1 General control group; Group 2 Swimming control group. Group 3 CAPE supplemented general control group. Group 4 CAPE supplemented swimming group. Furthermore, animals used in the experiment were made to do exhaustion practice toward the end of the examination. Plasma and liver tissue asymmetric dimethylarginine (ADMA) concentrations were not significantly (p0.05) increased in rats with acute swimming exercise compared to controls. Blood and liver cytokines levels were expanded in comparison to control group and CAPE groups (p0.05). Total antioxidant status (TAS) levels in acute swimming exercise groups reduced compared to the control group. Besides, total oxidant status (TOS) levels were considerably elevated compared to the control and CAPE groups. In this study, acute swimming exercise induced that oxidative stress could cause early onset of endothelial damage. Besides, CAPE can demonstrate protective effects on endothelial damage, inflammation and oxidative stress axis.Iodine plays an important role in thyroid function. see more However, in daily practices, people lack the related details including the knowledge concerned iodine usage, attitudes towards it, and practice among pregnant women. The aim of the present study is to assess the iodine status of pregnant women in Shanghai, and their knowledge regarding iodine, with the goal of investigating the relationship between iodine and thyroid function during pregnancy. This is a cross-sectional study. We recruited 3 groups of participants including 145 pregnant women (12-16 weeks gestation), 101 pregnant women (24-28 weeks gestation), and 108 pregnant women (34-38 weeks gestation). Iodine status and dietary intake were calculated from 24-h urinary iodine concentration (UIC). Knowledge regarding iodine was collected through a questionnaire. We additionally examined TSH, FT3, FT4, and TPOAb of the participants. The median of UIC of the 354 pregnant women was 119.2 μg/L, and 68.9% had urinary iodine levels below 150 μg/L. The proportion of daily iodized salt consumption in pregnant women was only 78.0%. The median UIC of the pregnant women who had consumed iodized salt was significantly higher than that of the pregnant women without iodized salt intake (Z = - 5.087, P  less then  0.001). Pregnant women in weeks 34-38 with a high level of knowledge had significantly lower TSH levels than those with low knowledge level (P = 0.046). Among the 349 pregnant women, few were aware of the harm to the fetus (8.3%). Significant differences were found in the scores for the knowledge level of women with different educational levels (Z = - 5.413, P  less then  0.001). Pregnant women in Shanghai have mild iodine deficiency. Approaches to improve iodine status among pregnant women in Shanghai include raising their awareness of iodine intake and changing their dietary habits. Otherwise, the risk of iodine deficiency in pregnant women may continue to increase.The neurotoxic effects of aluminum (Al) are associated with the impairment of synaptic plasticity, the biological basis of learning and memory, the major form of which is long-term potentiation (LTP). The canonical glycogen synthase kinase-3β (GSK-3β)/β-catenin signaling-mediated brain-derived neurotrophic factor (BDNF) pathway has been suggested to play important roles in memory. Thus, Al may affect LTP through this pathway. In this study, a Sprague-Dawley rat model of neurotoxicity was established through intracerebroventricular (i.c.v.) injection of aluminum maltol (Al(mal)3), which was achieved by preimplantation of a cannula into the lateral ventricle. The rats in the control and Al-treated groups received a daily injection of SB216763, an inhibitor of GSK-3β. Electrophysiology and western blot analysis were used to investigate the regulatory effect of the GSK-3β/β-catenin signaling-mediated BDNF pathway on LTP impairment induced by Al(mal)3. The results confirmed that i.c.v. injection of Al(mal)3 significantly suppressed the field excitatory postsynaptic potential (fEPSP) amplitude, as indicated by a decrease in BDNF protein expression, which was accompanied by dose-dependent decreases in β-catenin protein expression and the phosphorylation of GSK-3β at Ser9. Rats that received SB216763, a GSK-3β inhibitor, exhibited higher fEPSP amplitudes than control rats. Furthermore, SB216763 treatment upregulated the hippocampal protein expression of BDNF and β-catenin while increasing the ratio of p-GSK-3β/GSK-3β. From the perspective of the identified β-catenin-BDNF axis, Al impairs hippocampal LTP, possibly through the GSK-3β/β-catenin signaling-mediated BDNF pathway.In this study, a simple, low-cost, rapid, and eco-friendly approach for the biosynthesis of silver nanoparticles (AgNPs) using the aqueous extract of Cuminum cyminum L. (cumin) seed (CcAgNPs) was developed. Also, the anti-nociceptive properties of these synthesized AgNPs were evaluated in vivo. The CcAgNPs characterized using Ultraviolet-visible (UV-Vis) spectrophotometer, X-ray diffraction analysis (XRD), Fourier transform infrared (FTIR) spectroscopy, atomic force microscopy (AFM), and transmission electron microscopy (TEM). The analysis of phytochemical components in the aqueous extract of cumin seeds showed high concentrations of total phenols and ascorbic acid and low concentrations of total flavonoids. The analysis of phytochemical components and FTIR spectroscopy confirmed the presence of functional groups responsible for the bioreduction of Ag+ to AgNPs. The UV-Vis absorbance spectrum of CcAgNPs showed a maximum wavelength at 442 nm. The analysis of TEM images showed a spherical shape with a size of less than 50 nm, while XRD spectra revealed the crystallinity of CcAgNPs. The analysis of anti-nociceptive properties of CcAgNPs showed that the first phase of formalin-induced pain was significantly reduced in the groups receiving 200, 500, and 1000 mg/kg CcAgNPs compared with the controls and the group receiving 300 mg/kg of sodium salicylate (SS300). The second phase of formalin pain was also significantly reduced in the groups receiving 200 and 500 mg/kg CcAgNPs compared to the controls and SS300 group. Overall, we introduced a new AgNPs synthesized from cumin seeds (CcAgNPs) and showed their anti-nociceptive properties in the formalin-induced pain.
