Usage of Natural Health Products (NHPs) for respiratory diseases: user characteristics and NHP-Consumption behavior during the Covid-19 pandemic in Germany.

Background: Respiratory diseases (RD) can challenge healthcare systems around the globe. Natural health products (NHPs) are popular complementary and alternative medicine options for health issues concerning non-fatal RD. Little is known about the characteristics of the users of RD-NHPs and about their NHP consumption behavior during the Covid-19 pandemic in Germany.

Dementia 360 ECHO: Using technology to facilitate diagnosis and treatment.

Dementia affects one in ten adults over age 65. Paradoxically, dementia (e.g.

Project ECHO Integrated Within the Oregon Rural Practice-based Research Network (ORPRN).

Two key advancements in improving the quality of primary care have been practice-based research networks (PBRNs) and Project Extension for Community Health care Outcomes (ECHO). PBRNs advance quality through research and transformation projects, often using practice facilitation. Project ECHO uses case-based telementoring to support community clinicians to deliver best-practice care.

T cell receptor dwell times control the kinase activity of Zap70.

Kinase recruitment to membrane receptors is essential for signal transduction. However, the underlying regulatory mechanisms are poorly understood. We investigated how conformational changes control T cell receptor (TCR) association and activity of the kinase Zap70.

[Nutritional status of beneficiaries of the ¨Bolsa Família¨ Program in Brazil - a systematic review].

Various programs to combat malnutrition have been implemented over the years in Brazil. Since 2001, it has been the responsibility of the Bolsa Família Program (BFP). Despite the expansion of BFP, to date there has been little coverage charting the advances and challenges to be faced as well as the impacts on health and nutrition of the population.

Nectin-3 links CRHR1 signaling to stress-induced memory deficits and spine loss.

Stress impairs cognition via corticotropin-releasing hormone receptor 1 (CRHR1), but the molecular link between abnormal CRHR1 signaling and stress-induced cognitive impairments remains unclear. We investigated whether the cell adhesion molecule nectin-3 is required for the effects of CRHR1 on cognition and structural remodeling after early-life stress exposure. Postnatally stressed adult mice had decreased hippocampal nectin-3 levels, which could be attenuated by CRHR1 inactivation and mimicked by corticotropin-releasing hormone (CRH) overexpression in forebrain neurons.

Homer1 mediates acute stress-induced cognitive deficits in the dorsal hippocampus.

In recent years, the glutamatergic system has been implicated in the development and treatment of psychiatric disorders. Glutamate signaling is processed by different receptors, including metabotropic glutamate receptors (mGluRs), which in turn interact with the scaffolding protein Homer1 to modulate downstream Ca(2+) signaling. Stress is a major risk factor for the incidence of psychiatric diseases, yet acute stress episodes may have diverging effects on individuals.

Cingulate cortex aplasia and callosal dysgenesia combined with schizencephaly in a patient with chronic lying.

We report on a 19-year-old patient with a 4-year history of lying and cheating who presented neuropsychological abnormalities regarding attention deficits, hyperactivity and impulsivity. Cerebral magnetic resonance imaging scans revealed schizencephaly of the right central region, dysgenesia of the corpus callosum, a noneverted gyrus cinguli and hypoplasia of the left cerebellar hemisphere. Although the patient did not fulfill the diagnostic criteria for attention-deficit/hyperactivity disorder, we suggest that the patient's behavioral alteration could be related to the neuroanatomical alterations, especially the aplasia of the gyrus cinguli.

Forebrain CRF₁ modulates early-life stress-programmed cognitive deficits.

Childhood traumatic events hamper the development of the hippocampus and impair declarative memory in susceptible individuals. Persistent elevations of hippocampal corticotropin-releasing factor (CRF), acting through CRF receptor 1 (CRF₁), in experimental models of early-life stress have suggested a role for this endogenous stress hormone in the resulting structural modifications and cognitive dysfunction. However, direct testing of this possibility has been difficult.

The involvement of FK506-binding protein 51 (FKBP5) in the behavioral and neuroendocrine effects of chronic social defeat stress.

Chronic stress is increasingly considered to be a main risk factor for the development of a variety of psychiatric diseases such as depression. This is further supported by an impaired negative feedback of the hypothalamic-pituitary-adrenal (HPA) axis, which has been observed in the majority of depressed patients. The effects of glucocorticoids, the main hormonal endpoint of the HPA axis, are mediated via the glucocorticoid receptor (GR) and the mineralocorticoid receptor.

Forebrain CRHR1 deficiency attenuates chronic stress-induced cognitive deficits and dendritic remodeling.

Chronic stress evokes profound structural and molecular changes in the hippocampus, which may underlie spatial memory deficits. Corticotropin-releasing hormone (CRH) and CRH receptor 1 (CRHR1) mediate some of the rapid effects of stress on dendritic spine morphology and modulate learning and memory, thus providing a potential molecular basis for impaired synaptic plasticity and spatial memory by repeated stress exposure. Using adult male mice with CRHR1 conditionally inactivated in the forebrain regions, we investigated the role of CRH-CRHR1 signaling in the effects of chronic social defeat stress on spatial memory, the dendritic morphology of hippocampal CA3 pyramidal neurons, and the hippocampal expression of nectin-3, a synaptic cell adhesion molecule important in synaptic remodeling.

Localization dominance and the effect of frequency in the Mongolian Gerbil, Meriones unguiculatus.

Due to its good low-frequency hearing, the Mongolian Gerbil (Meriones unguiculatus) has become a well-established animal model for human hearing. In humans, sound localization in reverberant environments is facilitated by the precedence effect, i.e.

Chronic social stress during adolescence induces cognitive impairment in aged mice.

Age-related cognitive decline is one of the major aspects that impede successful aging in humans. Environmental factors, such as chronic stress, can accelerate or aggravate cognitive deficits during aging. While there is abundant evidence that chronic stress directly affects cognitive performance, the lasting consequences of stress exposures during vulnerable developmental time windows are largely unknown.
