Pharmacokinetics of 7,8-dihydroxyflavone in neonatal mice with hypoxia-ischemia related brain injury.

Introduction: 7,8-Dihydroxyflavone (7,8-DHF) is a promising translational therapy in several brain injury models, including the neonatal hypoxia-ischemia (HI) model in mice. However, the neuroprotective effect of 7,8-DHF was only observed in female, but not male, neonatal mice with HI brain injury. It is unknown whether HI-induced physiological changes affect brain distribution of 7,8-DHF differently for male versus female mice.

Health checks for autistic adults: study protocol for a cluster randomised controlled trial.

Background: Autistic people commonly have physical and mental health conditions. They also frequently experience barriers to accessing healthcare, contributing to problems identifying and treating health conditions. These factors may lead to increased and earlier morbidity and lower average life expectancy for autistic people.

Phase II Clinical Chemoprevention Trial of Weekly Erlotinib before Bladder Cancer Surgery.

We performed a clinical trial in patients with non-muscle-invasive (NMI) urothelial cancer randomized (2:1) to the EGFR tyrosine kinase inhibitor erlotinib or placebo (either orally once weekly × 3 doses prior to scheduled surgery) to assess for a difference in EGFR phosphorylation in tumor-adjacent normal urothelium <24 hours post-study dose and tolerance of weekly erlotinib therapy. Thirty-seven volunteers (6 female/31 male; mean age 70; 35 White/2 non-White) with confirmed or suspected NMI urothelial cancer were enrolled into either erlotinib (n = 24; 900 mg-13, 600 mg-11) or placebo (n = 13). IHC assessment of phosphorylated and total EGFR in tumor-adjacent normal urothelium (20 erlotinib and 9 placebo subjects) or tumor (21 erlotinib and 11 placebo subjects) at study end showed no significant difference between those receiving erlotinib or placebo.

In Vitro and in Silico Study of New Biscoumarin Glycosides from Paramignya trimera against Angiotensin-Converting Enzyme 2 (ACE-2) for Preventing SARS-CoV-2 Infection.

In Vietnam, the stems and roots of the Rutaceous plant Paramignya trimera (Oliv.) Burkill (known locally as "Xáo tam phân") are widely used to treat liver diseases such as viral hepatitis and acute and chronic cirrhosis. In an effort to search for Vietnamese natural compounds capable of inhibiting coronavirus based on molecular docking screening, two new dimeric coumarin glycosides, namely cis-paratrimerin B (1) and cis-paratrimerin A (2), and two previously identified coumarins, the trans-isomers paratrimerin B (3) and paratrimerin A (4), were isolated from the roots of P.

Novel extended-release transdermal formulations of the psychedelic N,N-dimethyltryptamine (DMT).

There is considerable evidence from the literature that psychedelics, such as N,N-dimethyltryptamine (DMT), are safe and effective treatments for depression. However, clinical administration to induce psychedelic effects and expensive psychotherapy-assisted treatments likely limit accessibility to the average patient. There is emerging evidence that DMT promotes positive behavioral changes in vivo at sub-hallucinogenic dosages, and depending on the target indication, subjecting patients to high, bolus dosages may not be necessary.

validation of psilacetin as a prodrug yielding modestly lower peripheral psilocin exposure than psilocybin.

Introduction: The use of the psychedelic compound psilocybin in conjunction with psychotherapy has shown promising results in the treatment of psychiatric disorders, though the underlying mechanisms supporting these effects remain unclear. Psilocybin is a Schedule I substance that is dephosphorylated to form an active metabolite, psilocin. Psilacetin, also known as O-acetylpsilocin or 4-acetoxy-N,N-dimethyltryptamine (4-AcO-DMT), is an unscheduled compound that has long been suggested as an alternative psilocin prodrug, though direct support for this hypothesis has thus far been lacking.

Effects of Soy Protein Isolate on Fragile X Phenotypes in Mice.

Obesity is a pediatric epidemic that is more prevalent in children with developmental disabilities. We hypothesize that soy protein-based diets increase weight gain and alter neurobehavioral outcomes. Our objective herein was to test matched casein- and soy protein-based purified ingredient diets in a mouse model of fragile X syndrome, mice.

Novel piperazine-1,2,3-triazole leads for the potential treatment of pancreatic cancer.

From lead 1, (-(4-((4-(3-(4-(3-methoxyphenyl)-1-1,2,3-triazol-1-yl)propyl)piperazin-1-yl)sulfonyl)-phenyl)acetamide), a S100A2-p53 protein-protein interaction inhibitor based on an modelling driven hypothesis, four focused libraries were designed and synthesised. Growth inhibition screening was performed against 16 human cancer cell lines including the pancreatic cell lines MiaPaCa2, BxPC3, AsPC-1, Capan-2, HPAC, PANC-1 and the drug resistant CFPAC1. Modification of 1's phenylacetamide moiety, gave with only modest pancreatic cancer activity.

Salt-Taste Polymorphism TRPV1-rs8065080 Is Associated with Increased Likelihood of Depression in an Elderly Cohort.

Introduction: Despite the prevalence of depression and anxiety worldwide, their aetiologies remain unclear, and they can be difficult to diagnose and treat. Changes in salt-taste perception have been found in both conditions. Single-nucleotide polymorphisms (SNPs) in the salt-taste-related gene, TRPV1, have been associated with alterations to salt-taste perception, preference, and sodium consumption.

Pharmacokinetic analysis of acute and dietary exposure to piperonyl butoxide in the mouse.

Piperonyl butoxide (PBO) is a popular insecticide synergist present in thousands of commercial, agricultural, and household products. PBO inhibits cytochrome P450 activity, impairing the ability of insects to detoxify insecticides. PBO was recently discovered to also inhibit Sonic hedgehog signaling, a pathway required for embryonic development, and rodent studies have demonstrated the potential for PBO exposure to cause structural malformations of the brain, face, and limbs, or more subtle neurodevelopmental abnormalities.

Liking of salt is associated with depression, anxiety, and stress.

Early research has shown variations in salt taste qualities in depression, anxiety, and stress. These studies evaluated changes to salt taste intensity and liking (pleasantness) of salt solutions but not of salty foods. Therefore, an Australian population survey (n = 424) was conducted where participants rated recalled intensity and liking of salt index foods and completed the Depression, Anxiety, and Stress Scale (DASS-21) to measure these states.

Hunger, temptation, and dietary adherence during weight management.

Preliminary evidence suggests that hunger and temptation may predict nonadherence to dietary intake goals; however, no studies have investigated the potential interaction between hunger and temptation in relation to dietary nonadherence nor have any investigated whether these associations may be different after the end of active behavioral intervention. Thus, the current study examined the week-to-week associations between hunger, temptation, and dietary adherence in 74 adults with overweight or obesity (mean ± SD age = 50.7 ± 10.

The Mechanistic Roles of Sirtuins in Breast and Prostate Cancer.

Mammalian sirtuins (SIRT1-7) are involved in a myriad of cellular processes, including apoptosis, proliferation, differentiation, epithelial-mesenchymal transition, aging, DNA repair, senescence, viability, survival, and stress response. In this review, we discuss the current information on the mechanistic roles of SIRT1-7 and their downstream effects (tumor promotion or suppression) in cancers of the breast and prostate. Specifically, we highlight the involvement of sirtuins in the regulation of various proteins implicated in proliferation, apoptosis, autophagy, chemoresistance, invasion, migration, and metastasis of breast and prostate cancer.

Background: Compared with the general population, autistic adults experience higher rates of physical and mental health conditions, premature morbidity and mortality, and barriers to health care. A health check for autistic people may improve their health outcomes.

Aim: To establish the views of autistic people towards a primary care health check for autistic people.

Under-Oil Autonomously Regulated Oxygen Microenvironments: A Goldilocks Principle-Based Approach for Microscale Cell Culture.

Oxygen levels in vivo are autonomously regulated by a supply-demand balance, which can be altered in disease states. However, the oxygen levels of in vitro cell culture systems, particularly microscale cell culture, are typically dominated by either supply or demand. Further, the oxygen microenvironment in these systems is rarely monitored or reported.

S100A2 is a Ca binding protein with implications in cell signaling and is known to be upregulated in pancreatic cancer. It is a validated pancreatic cancer drug target.

Proteomic Correlates of Enhanced Daptomycin Activity following β-Lactam Preconditioning in Daptomycin-Resistant, Methicillin-Resistant Staphylococcus aureus.

Clinical treatment options for daptomycin (DAP)-resistant (DAP-R), methicillin-resistant Staphylococcus aureus (MRSA) infections are relatively limited. Current therapeutic strategies often take advantage of potential synergistic activity of DAP plus β-lactams; however, the mechanisms underlying their combinatorial efficacy are likely complex and remain incompletely understood. We recently showed that β-lactam passaging can resensitize DAP-R strains to a DAP-susceptible (DAP-S) phenotype.

Sour Taste SNP -rs236514 and Differences in Nutrient Intakes and Metabolic Health Markers in the Elderly.

Single nucleotide polymorphisms (SNPs) in taste receptors influence dietary choices that contribute to health and quality of life. Individual differences in sour taste perception and preference have been linked to heritable genetics, yet the impact of sour taste receptor SNPs on sour taste is under-researched, and studies on sour taste SNP associations to diet and health are lacking. Therefore, this study explored the relationships between the sour taste SNP -rs236514 and estimated macronutrient, vitamin and mineral intakes, and markers of metabolic health.

Biophysical evidence to support and extend the vitamin D-folate hypothesis as a paradigm for the evolution of human skin pigmentation.
