Adolescence is a developmental period characterized by substantial biological, neural, behavioral, and social changes. Learning to navigate the complex social world requires adaptive skills. Although anticipation of social situations can serve an adaptive function, providing opportunity to adjust behavior, socially anxious individuals may engage in maladaptive anticipatory processing. Importantly, elevated social anxiety often coincides with adolescence. This study investigated cortical electroencephalogram (EEG) responses during anticipation of evaluative feedback in 106 healthy adolescents aged 12-17 years. We examined differences in anticipatory event-related potentials (i.e., stimulus preceding negativity [SPN]) in relation to social anxiety levels and pubertal maturation. https://www.selleckchem.com/JAK.html As expected, the right frontal SPN was more negative during feedback anticipation, particularly for adolescents with higher social anxiety and adolescents who were at a more advanced pubertal stage. Effects for the left posterior SPN were the opposite of those for the right frontal SPN consistent with a dipole. Anticipatory reactivity in adolescence was related to social anxiety symptom severity, especially in females, and pubertal maturation in a social evaluative situation. This study provides evidence for the development of social anticipatory processes in adolescence and potential mechanisms underlying maladaptive anticipation in social anxiety.Neighborhood disadvantage has consistently been linked to alterations in brain structure; however, positive environmental (e.g., positive parenting) and psychological factors (e.g., temperament) may buffer these effects. We aimed to investigate associations between neighborhood disadvantage and deviations from typical neurodevelopmental trajectories during adolescence, and examine the moderating role of positive parenting and temperamental effortful control (EC). Using a large dataset (n = 1313), a normative model of brain morphology was established, which was then used to predict the age of youth from a longitudinal dataset (n = 166, three time-points at age 12, 16, and 19). Using linear mixed models, we investigated whether trajectories of the difference between brain-predicted-age and chronological age (brainAGE) were associated with neighborhood disadvantage, and whether positive parenting (positive behavior during a problem-solving task) and EC moderated these associations. We found that neighborhood disadvantage was associated with positive brainAGE during early adolescence and a deceleration (decreasing brainAGE) thereafter. EC moderated this association such that in disadvantaged adolescents, low EC was associated with delayed development (negative brainAGE) during late adolescence. Findings provide evidence for complex associations between environmental and psychological factors, and brain maturation. They suggest that neighborhood disadvantage may have long-term effects on neurodevelopment during adolescence, but high EC could buffer these effects.Microbial pumping rhodopsin is a seven-transmembrane retinal binding protein, which is light-driven ion pump with a functional key motif. Ion-pumping with the key motif and charged amino acids in the rhodopsin is biochemically important. The rhodopsins with DTG motif have been discovered in various eubacteria, and they function as H+ pump. Especially, the DTG motif rhodopsins transported H+ despite the replacement of a proton donor by Gly. We investigated Methylobacterium populi rhodopsin (MpR) in one of the DTG motif rhodopsin clades. To determine which ions the MpR transport, we tested with various monovalent ion solutions and determined that MpR transports Li+/Na+. By replacing the three negatively charged residues residues which are located in helix B, Glu32, Glu33, and Asp35, we concluded that the residues play a critical role in the transport of Li+/Na+. The MpR E33Q transported H+ in place of Li+/Na+, suggesting that Glu33 is a Li+/Na+ binding site on the cytoplasmic side. Gly93 in MpR was replaced by Asp to convert from the Li+/Na+ pump to the H+ pump, resulting in MpR G93D transporting H+. Dissociation constant (Kd) values of Na+ for MpR WT and E33Q were determined to be 4.0 and 72.5 mM, respectively. These results indicated the mechanism by which MpR E33Q transports H+. Up to now, various ion-pumping rhodopsins have been discovered, and Li+/Na+-pumping rhodopsins were only found in the NDQ motif in NaR. Here, we report a new light-driven Na+ pump MpR and have determined the important residues required for Li+/Na+-pumping different from previously known NaR.
The established Beers Criteria consider side effects and safety concerns when prescribing drugs to the elderly. As the criteria suggest that attention should be paid toward prescriptions rather than prescription prohibition lists, these Beers Criteria medications (BCMs) are used appropriately under unavoidable circumstances.

Patients aged≥65years and with an experience of being prescribed inappropriate medications at Konyang University Hospital, South Korea, were selected. We analyzed data from the Korea Adverse Event Reporting System (KAERS) and the Food and Drug Administration Adverse Event Reporting System (FAERS) of the United States to identify medication-induced adverse drug events (ADEs). The actual incidence was predicted by multiplying the incidence and number of BCMs prescribed to the patients. The proportional reporting ratio (PRR) and reporting odds ratio (ROR) were calculated using KAERS and FAERS data.

We predicted that the incidence of ADEs would be higher for metoclopramide, chlorpheniramine, and amitriptyline in patients using medications for more than 1day and metoclopramide, chlorpheniramine, and ketoprofen in patients using medications only for 1day. Among the ADEs reported to KAERS and FAERS, significant ROR and PRR values were noted for clonazepam (drowsiness), nortriptyline (sleepiness), and zolpidem (amnesia, somnambulism, agitation, dependence, nightmare, and dysgeusia).

This study highlighted the actual status of BCM prescriptions in clinical institutions and predicted the incidence of ADEs. We concluded that greater care must be taken while prescribing BCMs to the elderly and indicators, such as PRR and ROR should be monitored regularly.

To investigate whether patients with benign childhood epilepsy with centrotemporal spikes (BECTS) and childhood absence epilepsy (CAE) show distinct patterns of white matter (WM) alterations and structural asymmetry compared with healthy controls and the relationship between WM alterations and epilepsy-related clinical variables.

We used automated fiber quantification to create tract profiles of fractional anisotropy (FA) and mean diffusivity (MD) in twenty-six patients with BECTS, twenty-nine patients with CAE, and twenty-four healthy controls. Group differences in FA and MD were quantified at 100 equidistant nodes along the fiber tract and these alterations and epilepsy-related clinical variables were correlated. A lateralization index (LI) representing the structural asymmetry of the fiber tract was computed and compared between both patient groups and controls.

Compared with healthy controls, the BECTS group showed widespread FA reduction in 43.75% (7/16) and MD elevation in 50% (8/16) of identified fiber tracts, and the CAE group showed regional FA reduction in 31.25% (5/16) and MD elevation in 25% (4/16) of identified fiber tracts. In the BECTS group, FA and MD in the right anterior thalamic radiation positively and negatively correlated with the number of antiepileptic drugs, respectively, and MD in the right arcuate fasciculus (AF) positively correlated with seizure frequency. In the CAE group, the LI values were significantly lower in the inferior fronto-occipital fasciculus and the AF.

The two childhood epilepsy syndromes display different patterns of WM alterations and structural asymmetry, suggesting that neuroanatomical differences may underlie the different profiles of BECTS and CAE.

Pregnancy registries for women with epilepsy (WWE) are arising all over the world. The aim of this work was to assess the risk factors of pregnancy losses and major birth defects (MBDs) of WWE through the Egyptian Registry of Anti-seizure medications and Pregnancy system.

An observational prospective study was conducted over 24 months (2018-2020). The following data were assessed seizure control during pregnancy, Anti-seizure medications (ASMs) regimen, folic acid supplementation, and birth outcome.

This study included 211 pregnant WWE, with mean age of 27.30 ± 5.51 years. One hundred eighty-six (89.9%) patients were on ASMs, from which 110 (59.1%) patients were on monotherapy. One hundred sixty-nine (80.0%) had healthy living babies, while fetal deaths occurred in 27 patients (12.8%) (25 abortions and 2 stillbirth), two patients (1%) had neonatal deaths, while 13 patients (6.2%) had living babies with MBDs. Although taking folic acid in the first trimester was a protective of fetal deaths (RR < 1, P 0.011), it was not a protective of MBDs. Seizure freedom during the entire pregnancy regardless of seizure type was another protective factor against fetal deaths (RR < 1, P < 0.001). Polytherapy exposure significantly increased the risk of MBDs compared with monotherapies (RR > 1, P 0.014). History of previous MBD was another risk factor of MBDs (RR > 1, P 0.027).

History of previous MBD and polytherapy exposure increased the risk of MBDs. Taking folic acid during first trimester and being seizure free during pregnancy were protective factors against fetal deaths.

Insomnia identity, the conviction that one has insomnia, occurs independently of sleep quality or quantity, and is associated with numerous negative health outcomes. Little is known about factors influencing insomnia identity. This study planned to evaluate insomnia identity, perceived sleep experience, and sleep parameters.

Individuals seeking treatment for an insomnia complaint reported demographics, insomnia identity ratings, and daily sleep diaries. Insomnia complaint and insomnia identity were independently crossed with sleep diary data yielding complaining good (n=10) and poor sleepers (n=51), and good (n=7) and poor sleepers (n=40) with insomnia identity. Participants were additionally classified as with (n=50) and without (n=14) insomnia identity. Group differences and predictors of insomnia identity were assessed.

Complaining poor sleepers and poor sleepers with insomnia identity reported significantly poorer sleep ratings compared to their counterparts. Insomnia identity severity was predicted by worse sleep quality comparisons and increased helplessness.
