Tetrandrine promotes angiogenesis through transcriptional unsafe effects of VEGF-A.
Gene transfection is important in biotechnology and is used to modify cells intrinsically. It can be conducted in cell suspension or after cell adhesion, where the efficiency is dependent on many factors such as the type of nanocarrier used and cell division processes. Anchor-dependent cells are sensitive to the substrate they are attached to and adapt their behavior accordingly, including plasmid trafficking during gene transfection. Previously, it was shown in our group that the cytoskeleton is an essential factor in influencing gene transfection in skeletal myoblasts using nanogrooves as a substrate. In this study, the effect of the cytoskeleton on gene transfection efficiency of skeletal myoblasts was studied using various nanopillars and nanocarriers. Nanopillars with different diameters (200-1000 nm) and depths (200 or 400 nm) were fabricated using colloidal self-assembly and reactive ion etching. All surfaces were treated with oxygen plasma or polydopamine (PD) to further control cell morphology. Plasm of nanocarrier/plasmid complexes and this study provides new insights into gene transfection in anchor-dependent cells.Although cognitive behavioral interventions improve attitudes toward mental health treatment and reduce stigma, little is known about which types of attitudes change, or how this change occurs. Active duty soldiers with PTSD (N = 162) were randomized to 10 sessions of exposure therapy or a waitlist. Soldiers were assessed for PTSD and completed measures of stigma and attitudes towards mental health services before randomization and after 5- and 10- sessions of therapy. At post-treatment, soldiers in exposure therapy demonstrated significant improvements in openness to talking about mental health problems and concerns about what others may think if they knew they were seeking mental health treatment, relative to those in the waitlist. There were significant indirect effects from treatment to changes in stigma and attitudes towards mental health treatment through changes in PTSD symptoms at post-treatment. There was also a significant indirect effect from treatment to changes in stigma at post-treatment through changes in attitudes towards mental health treatment at mid-treatment, suggesting attitude change may occur first. Baseline characteristics did not moderate treatment's change in stigma or attitudes. Improvements in PTSD symptoms and positive changes in attitudes towards mental health treatment appear to separately predict later reductions in stigma.In psychiatric patients, medication adverse effects are regularly attributed to psychosomatic causes. However, many psychotropic medications are metabolized by cytochrome P450 (CYP450) enzymes. In the setting of polypharmacy, the activity of these enzymes may produce unfavorable drug-drug interactions (DDI) and drug-genotype interactions (DGI) that contribute to morbidity and mortality. This study sought to estimate the risk of adverse DDI and DGI in psychiatric inpatients with polypharmacy. We assessed whether medication changes made after pharmacogenetics (PGx) testing correlated with changes in side effects and overall improvement. Adult psychiatry inpatients with polypharmacy, defined as 5 or more scheduled prescription medications, completed the 24-item Antidepressant Side Effect Checklist (ASEC) questionnaire on enrollment and underwent PGx testing. Analysis of PGx results focused on whether the CYP2D6 and CYP2C19 phenotypes were "extreme," defined as poor, poor to intermediate, or ultrarapid. Approximately 30 days after PGx results were sent to outpatient providers, patients were contacted to obtain their current medication list and ASEC and Clinical Global Impression Improvement (CGI-I) scores. A total of 80 patients were enrolled, and 52 (65%) completed follow-up. ASEC scores improved from 11.5 (±8.1) to 7.2 (±6.0) (p = 0.0009). Mean CGI-I score was 2.7 (±1.4), between "minimal" to "much improved." However, linear regression revealed that these improvements were not correlated with whether medications were changed. We concluded that the impact of drug-genotype interactions in this small sample of inpatients with polypharmacy was low, and that patient improvement was related not to PGx-guided medication changes but to other treatments during hospitalization.Many individuals with peanut (PN) allergy have severe reactions to tree nuts (TN) such as walnuts or cashews. Although allergenic proteins in TN and PN have overall low identity, they share discrete sequences similar in physicochemical properties (PCP) to known IgE epitopes. Here, PCP-consensus peptides (cp, 13 aa and 31 aa) were identified from an alignment of epitope rich regions of walnut vicilin, Jug r 2, leader sequence (J2LS) and cross-reactive epitopes in the 2S albumins of peanut and synthesized. A peptide similarity search in the Structural Database of Allergenic Proteins (SDAP) revealed a network of peptides similar (low property distance, PD) to the 13 aa cp (13cp) in many different plant allergens. Peptides similar to the 13cp in PN and TN allergens bound IgE from sera of patients allergic to PN and TN in peptide microarray analysis. The 13cp was used to produce a rabbit consensus peptide antibody (cpAB) that detected proteins containing repeats similar to the 13cp in western blots of various nut extracts, in which reactive proteins were identified by mass spectrometry. The cpAB bound more specifically to allergens and nut extracts containing multiple repeats similar to the 13 cp, such as almond (Pru du 6), peanut (Ara h 2) and walnut (Jug r 2). IgE binding to various nut extracts is inhibited by recombinant J2LS sequence and synthetic 31cp. Thus, several repeated sequences similar to the 13cp are bound by IgE. Multiple similar repeats in several allergens could account for reaction severity and clinically relevant cross-reactivity to PN and TN.

At present, the baking industry creates food-grade waste as excess and deformed products that are mainly utilized for non-food uses, such as bioethanol production. The purpose of this study was therefore to explore the potential of waste wheat bread recycling for fresh wheat bread production. Waste bread recycling was assessed without further processing or after tailored fermentation with lactic acid bacteria producing either dextran or β-glucan exopolysaccharides. When non-treated waste bread slurry was added to new bread dough, bread quality (specific volume and softness) decreased with increasing content of waste bread addition. In situ EPS-production (dextran and microbial β-glucan) significantly increased waste bread slurry viscosity and yielded residual fructose or glucose that could effectively replace the sugar added for yeast leavening. Furthermore, fermentation acidified waste bread matrix, thus improving the hygienic safety of the process. Bread containing dextran synthesized in situ by Weissella confusa A16 showed good technological quality. The produced dextran compensated the adverse effect of recycled bread on new bread quality attributes by 12% increase in bread specific volume and 37% decrease in crumb hardness. In this study, a positive technological outcome of the bread containing microbial β-glucan was not detected. The waste bread fermented by W. confusa A16 containing dextran appears to enable safe bread recycling with low acidity and minimal quality loss.Verbal-auditory agnosia and aphasia are the most prominent symptoms in Landau-Kleffner syndrome (LKS), a childhood epilepsy that can have sustained long-term effects on language processing. The present study provides the first objective investigation of music perception skills in four adult patients with a diagnosis of LKS during childhood, covering the spectrum of severity of the syndrome from mild to severe. Pitch discrimination, short-term memory for melodic, rhythmic and verbal information, as well as emotion recognition in music and speech prosody were assessed with listening tests, and subjective attitude to music with a questionnaire. We observed amusia in 3 out of 4 patients, with elevated pitch discrimination thresholds and poor short-term memory for melody and rhythm. The two patients with the most severe LKS had impairments in music and prosody emotion recognition, but normal perception of emotional intensity of music. Overall, performance in music processing tasks was proportional to the severity of the syndrome. Nonetheless, the four patients reported that they enjoyed music, felt musical emotions, and used music in their daily life. These new data support the hypothesis that, beyond verbal impairments, cerebral networks involved in sound processing and encoding are deeply altered by the epileptic activity in LKS, well after electrophysiological normalization.Functional imaging studies have implicated an area in the left lateral fusiform gyrus, known as the visual word form area (VWFA), in pre-lexical orthographic processing. There are very few studies that have examined the functional specificity of this area in patients with discrete lesions limited to this region. Here we describe a rare opportunity to examine the functional specificity of the VWFA in a patient with stereo EEG (sEEG) electrodes implanted for localization of seizures prior to epilepsy surgery. sEEG offers the opportunity to create a transient and highly localized electrophysiological lesion to examine brain behavior correlates during functional mapping. In this case, word reading and writing as well as a variety of non-orthographic language functions (e.g., picture and face naming, auditory naming, and non-word repetition), were tested during electrical stimulation at a series of different electrode contact sites in the ventral temporal region. Pure alexia resulted from stimulation of the lateral fusiform gyrus at coordinates nearly identical to those published for the VWFA in the functional imaging literature.A fast-growing literature is establishing how moving in time together has pro-social consequences, though no work to date has explored the persistence of these effects over time. Across two studies, people who had previously performed coordinated movements were over three times more likely to give their time to help their co-actor when asked 24 hours later than those who had performed a similar but uncoordinated task. Findings showed that group-level categorisation, but not social affiliation, partially mediated helping behaviour. This provides preliminary evidence that the pro-social effects of coordination are sustainable over a longer period than previously reported, and that the effects of coordination upon pro-social motivation may be more related to changes in group level categorisations than increased social affiliations.Background Delayed care-seeking for heart failure symptoms increases the risk of unplanned and frequent hospitalization. Presenting to hospital at a later stage when symptoms are severe requires more complex treatment, contributing to longer lengths of stay and higher risk of mortality. Patient-related factors such as knowledge have been highlighted as key contributors to care-seeking delay, yet little is known about how previous experiences within the healthcare setting, including relationships with providers, influence decisions to engage with health services when required. Objective To assess patient-related factors thought to impact care-seeking, and examine the role of previous healthcare experiences in decisions to seek or avoid professional care. Design Sequential mixed-methods study with a phenomenological approach. Settings A cardiology in-patient ward in a quaternary referral hospital in Sydney, Australia. Participants A total of 72 symptomatic in-patients diagnosed with heart failure. Methods Self-efficacy, heart failure knowledge and health literacy were assessed quantitatively.
