The COVID-19 pandemic has caused a number of fundamental changes in different societies, and can therefore be understood as creating "disjuncture" in our lives. Disjuncture is a concept proposed by adult educator Peter Jarvis to describe the phenomenon of what happens when an individual is confronted with an experience that conflicts with her/his previous understanding of the world. CAY10683 Faced with a situation that creates disjuncture, the person is compelled to find new knowledge and new ways of doing things; i.e., he/she must embark on a learning process. The recent introduction of social distancing as a measure aiming to reduce transmission of the COVID-19 virus has dramatically changed people's behaviour, but this measure does not only have preventive and desirable effects. There is an associated risk for increased isolation among the older generations of the population, as well as a change in intergenerational relationships. Although the current pandemic (as disjuncture) may potentially initiate major learning processes in the human collective, we should remember that disjuncture is often theorised within neutral, or even positive, contexts. In a context of fear, however, learning may result in a narrowing of mindsets and a rejection of collective efforts and solidarity between generations. In terms of the types of learning triggered by the current pandemic (as disjuncture), one problem is non-reflective learning, which primarily occurs on a behavioural level. We need to recognise this and engage in reflective learning if we are to make the choices that will lead to a society that is worth living in for all generations. Our goal must be to learn to be a person in a post-pandemic society.A summary of recent applications of Lewis acid BF3·Et2O as a catalyst in the synthesis of cyclic organic peroxides is presented.Recent research studies have highlighted that the consumption of industrially produced trans-fatty acids (TFAs) causes detrimental effects on human health. The World Health Organization (WHO) has recommended the elimination of TFA from diets to reduce the risk of non-communicable diseases (NCDs). In this paper, we use WHO's REPLACE framework for a situation analysis of TFAs in Pakistan's context by reviewing the literature on its dietary and industrial sources along with the legislative and regulatory context surrounding TFA related affairs in Pakistan. To maintain the authenticity of the data and the various actions implemented in Pakistan, we interviewed government officials, experts and researchers engaged in this field. link2 By combining this information with a review of effective policies and best practices applied for TFA elimination around the world, we have prepared recommendations for policymakers in the country. The primary dietary sources of TFA in Pakistan are vanaspati ghee (partially hydrogenated vegetable oil), kinds of margarine, bakery shortenings and fat spreads. Whereas, their main producers are the edible oil, margarine, bakery and confectionary industries. Federal and provincial governments have introduced TFA regulations, but these vary across jurisdictions, complicating enforcement. Lack of credible penalties for violation of regulations, low public awareness and capacity and data gaps among regulators also inhibit TFA elimination. We recommend multi-stakeholder efforts for harmonization of mandatory TFA limits and labeling, replacement of traditional vanaspati ghee, communication efforts for behavioral change, promotion of replacement oils and strengthening regulators' assessment capacities.Objects constitute the fundamental currency of our consciousness they are the things that we perceive, remember and think about. One of the most important objects for a primate is a face. Research on the macaque face patch system in recent years has given us a remarkable window into the detailed processes underlying object recognition. Here, we review the macaque face patch system, including its anatomical organization, coding principles, role in behaviour and interactions with other brain regions. We highlight not only how it constitutes an archetypal object recognition system but also how it may provide a key to understanding mechanisms for higher cognitive function.Physical distancing has been the primary strategy to control COVID-19 in the United States. We used mobility data from a large, anonymized sample of smartphone users to assess the relationship between neighbourhood income and physical distancing during the pandemic. We found a strong gradient between neighbourhood income and physical distancing. Individuals in high-income neighbourhoods increased their days at home substantially more than individuals in low-income neighbourhoods did. Residents of low-income neighbourhoods were more likely to work outside the home, compared to residents in higher-income neighbourhoods, but were not more likely to visit locations such as supermarkets, parks and hospitals. Finally, we found that state orders were only associated with small increases in staying home in low-income neighbourhoods. Our findings indicate that people in lower-income neighbourhoods have faced barriers to physical distancing, particularly needing to work outside the home, and that state physical distancing policies have not mitigated these disparities.A consensus has yet to emerge whether deep brain stimulation (DBS) for treatment-refractory obsessive-compulsive disorder (OCD) can be considered an established therapy. In 2014, the World Society for Stereotactic and Functional Neurosurgery (WSSFN) published consensus guidelines stating that a therapy becomes established when "at least two blinded randomized controlled clinical trials from two different groups of researchers are published, both reporting an acceptable risk-benefit ratio, at least comparable with other existing therapies. link3 The clinical trials should be on the same brain area for the same psychiatric indication." The authors have now compiled the available evidence to make a clear statement on whether DBS for OCD is established therapy. Two blinded randomized controlled trials have been published, one with level I evidence (Yale-Brown Obsessive Compulsive Scale (Y-BOCS) score improved 37% during stimulation on), the other with level II evidence (25% improvement). A clinical cohort study (N = 70) showed 40% Y-BOCS score improvement during DBS, and a prospective international multi-center study 42% improvement (N = 30). The WSSFN states that electrical stimulation for otherwise treatment refractory OCD using a multipolar electrode implanted in the ventral anterior capsule region (including bed nucleus of stria terminalis and nucleus accumbens) remains investigational. It represents an emerging, but not yet established therapy. A multidisciplinary team involving psychiatrists and neurosurgeons is a prerequisite for such therapy, and the future of surgical treatment of psychiatric patients remains in the realm of the psychiatrist.Although APP metabolism is being intensively investigated, a large fraction of its modulators is yet to be characterized. In this context, we combined two genome-wide high-content screenings to assess the functional impact of miRNAs and genes on APP metabolism and the signaling pathways involved. This approach highlighted the involvement of FERMT2 (or Kindlin-2), a genetic risk factor of Alzheimer's disease (AD), as a potential key modulator of axon guidance, a neuronal process that depends on the regulation of APP metabolism. We found that FERMT2 directly interacts with APP to modulate its metabolism, and that FERMT2 underexpression impacts axonal growth, synaptic connectivity, and long-term potentiation in an APP-dependent manner. Last, the rs7143400-T allele, which is associated with an increased AD risk and localized within the 3'UTR of FERMT2, induced a downregulation of FERMT2 expression through binding of miR-4504 among others. This miRNA is mainly expressed in neurons and significantly overexpressed in AD brains compared to controls. Altogether, our data provide strong evidence for a detrimental effect of FERMT2 underexpression in neurons and insight into how this may influence AD pathogenesis.Depression is a common mental illness, affecting more than 300 million people worldwide. Decades of investigation have yielded symptomatic therapies for this disabling condition but have not led to a consensus about its pathogenesis. There are data to support several different theories of causation, including the monoamine hypothesis, hypothalamic-pituitary-adrenal axis changes, inflammation and immune system alterations, abnormalities of neurogenesis and a conducive environmental milieu. Research in these areas and others has greatly advanced the current understanding of depression; however, there are other, less widely known theories of pathogenesis. Oligodendrocyte lineage cells, including oligodendrocyte progenitor cells and mature oligodendrocytes, have numerous important functions, which include forming myelin sheaths that enwrap central nervous system axons, supporting axons metabolically, and mediating certain forms of neuroplasticity. These specialized glial cells have been implicated in psychiatric disorders such as depression. In this review, we summarize recent findings that shed light on how oligodendrocyte lineage cells might participate in the pathogenesis of depression, and we discuss new approaches for targeting these cells as a novel strategy to treat depression.The field of nutritional psychiatry has generated observational and efficacy data supporting a role for healthy dietary patterns in depression onset and symptom management. To guide future clinical trials and targeted dietary therapies, this review provides an overview of what is currently known regarding underlying mechanisms of action by which diet may influence mental and brain health. The mechanisms of action associating diet with health outcomes are complex, multifaceted, interacting, and not restricted to any one biological pathway. Numerous pathways were identified through which diet could plausibly affect mental health. These include modulation of pathways involved in inflammation, oxidative stress, epigenetics, mitochondrial dysfunction, the gut microbiota, tryptophan-kynurenine metabolism, the HPA axis, neurogenesis and BDNF, epigenetics, and obesity. However, the nascent nature of the nutritional psychiatry field to date means that the existing literature identified in this review is largely comprised of preclinical animal studies. To fully identify and elucidate complex mechanisms of action, intervention studies that assess markers related to these pathways within clinically diagnosed human populations are needed.

Prolonged exposure to high oxygen concentrations in premature infants, although lifesaving, can induce lung oxidative stress and increase the risk of developing BPD, a form of chronic lung disease. The lung alveolar epithelium is damaged by sustained hyperoxia, causing oxidative stress and alveolar simplification; however, it is unclear what duration of exposure to hyperoxia negatively impacts cellular function.

Here we investigated the role of a very short exposure to hyperoxia (95% O

, 5% CO

) on mitochondrial function in cultured mouse lung epithelial cells and neonatal mice.

In epithelial cells, 4 h of hyperoxia reduced oxidative phosphorylation, respiratory complex I and IV activity, utilization of mitochondrial metabolites, and caused mitochondria to form elongated tubular networks. Cells allowed to recover in air for 24 h exhibited a persistent global reduction in fuel utilization. In addition, neonatal mice exposed to hyperoxia for only 12 h demonstrated alveolar simplification at postnatal day 14.
