Article Synopsis
  • - Psychedelics, particularly psilocybin, are being researched as possible treatments for mental health issues like anxiety, depression, and OCD, showing promise in reducing symptoms.
  • - Early case studies and a 2006 trial indicated that psilocybin can significantly decrease OCD symptoms, with positive results also observed in animal studies.
  • - The exact ways psychedelics help with OCD are still not fully understood, prompting further research to explore their mechanisms and the effectiveness of ongoing psilocybin trials.

Myelin, along with the oligodendrocytes (OLs) that produce it, is essential for proper central nervous system (CNS) function in vertebrates. Although the accurate targeting of myelin to axons and its maintenance are critical for CNS performance, the molecular pathways that regulate these processes remain poorly understood. Through a combination of zebrafish genetics, mouse models, and primary OL cultures, we found FBXW7, a recognition subunit of an E3 ubiquitin ligase complex, is a regulator of adult myelination in the CNS.

Since 1971, North Carolina (NC) has been the leading sweetpotato-producing state in the United States (US) and is now producing more than half of the nation's annual output. Due to the high demand for US sweetpotatoes from international markets, NC allocates roughly 40% of its sweetpotatoes for export. However, low fungicide residue limits in primary export markets restricts the ability for NC producers to apply fungicides for disease management during sweetpotato production.

Objectives: Emergency Medical Services patients who survive overdose are at high risk for subsequent overdose and death. Programs that seek to link overdose survivors to harm reduction and treatment services are increasingly common, though they vary in design and measured effect. Public Health - Seattle & King County (PHSKC) used a continuous quality improvement (CQI) process to assess and improve a phone-based model for post-overdose outreach in King County, Washington.

Article Synopsis
  • TLRs (Toll-like receptors) start immune responses by using TIR (Toll/IL-1R) domains, but some bacteria have their own TIR proteins to evade immune detection.
  • Initial studies on a bacterial TIR from Acinetobacter baumannii revealed structural insights but didn't clarify how it binds NAD, leading to further investigation.
  • A collaborative research project involving undergraduates aimed to identify key amino acids for the NADase activity of TIR domains from A. baumannii and E. coli, providing new insights into their function and reaffirming the effectiveness of student-led research experiences.

There are widespread calls for increased demographic diversity in science, often linked to the epistemic claim that including more perspectives will improve the quality of the knowledge produced. By distinguishing between demographic and epistemic diversity, we show that this is only true some of the time. There are cases where increasing demographic diversity will not bring about the necessary epistemic diversity and cases where failing to some voices reduces the quality of the scientific debate.

Microglia take on an altered morphology during chronic opioid treatment. This morphological change is broadly used to identify the activated microglial state associated with opioid side effects, including tolerance and opioid-induced hyperalgesia (OIH). Microglia display similar morphological responses in the spinal cord after peripheral nerve injury (PNI).

Natural products contribute substantially to anticancer therapy; the plant kingdom provides an important source of molecules. Conofolidine is a novel bisindole alkaloid isolated from the Malayan plant . Herein, we report conofolidine's broad-spectrum anticancer activity together with that of three other bisindoles-conophylline, leucophyllidine, and bipleiophylline-against human-derived breast, colorectal, pancreatic, and lung carcinoma cell lines.

Alzheimer's disease (AD) is a progressive neurodegenerative disease with no effective treatments, not least due to the lack of authentic animal models. Typically, rodent models recapitulate the effects but not causes of AD, such as cholinergic neuron loss: lesioning of cholinergic neurons mimics the cognitive decline reminiscent of AD but not its neuropathology. Alternative models rely on the overexpression of genes associated with familial AD, such as amyloid precursor protein, or have genetically amplified expression of mutant tau.

Background: Preterm birth (before 37 completed weeks of gestation) is associated with an increased risk of adverse health and developmental outcomes relative to birth at term. Existing guidelines for data collection in cohort studies of individuals born preterm are either limited in scope, have not been developed using formal consensus methodology, or did not involve a range of stakeholders in their development. Recommendations meeting these criteria would facilitate data pooling and harmonisation across studies.

Article Synopsis
  • People are starting to believe in strange ideas like "alternative facts," which make it hard to find the truth.
  • To fix this, we should create a "veritocracy," where telling the truth is super important for politicians and everyone.
  • Science can help us understand and find the truth, not as a guaranteed answer but as a trusted way to learn about the world, just like the law helps keep things fair.

Research using animals depends on the generation of offspring for use in experiments or for the maintenance of animal colonies. Although not considered by all, several different factors preceding and during pregnancy, as well as during lactation, can program various characteristics in the offspring. Here, we present the most common models of developmental programming of cardiovascular outcomes, important considerations for study design, and provide guidelines for producing and reporting rigorous and reproducible cardiovascular studies in offspring exposed to normal conditions or developmental insult.

Maternal mortality rates are at an all-time high across the world and are set to increase in subsequent years. Cardiovascular disease is the leading cause of death during pregnancy and postpartum, especially in the United States. Therefore, understanding the physiological changes in the cardiovascular system during normal pregnancy is necessary to understand disease-related pathology.

Exercise training can promote physiological cardiac growth, which has been suggested to involve changes in glucose metabolism to facilitate hypertrophy of cardiomyocytes. In this study, we used a dietary, in vivo isotope labeling approach to examine how exercise training influences the metabolic fate of carbon derived from dietary glucose in the heart during acute, active, and established phases of exercise-induced cardiac growth. Male and female FVB/NJ mice were subjected to treadmill running for up to 4 weeks and cardiac growth was assessed by gravimetry.

Cessation of therapy with a selective serotonin (5-HT) reuptake inhibitor (SSRI) is often associated with an early onset and disabling discontinuation syndrome, the mechanism of which is surprisingly little investigated. Here we determined the effect on 5-HT neurochemistry of discontinuation from the SSRI paroxetine. Paroxetine was administered repeatedly to mice (once daily, 12 days versus saline controls) and then either continued or discontinued for up to 5 days.

  • The study aimed to examine how mitochondrial respiration in the maternal heart changes during pregnancy and after childbirth, using female mice as subjects.
  • Researchers found that the heart size increases during pregnancy and post-birth, and mitochondrial gene expression also changes, particularly in late pregnancy and one week after birth.
  • The findings indicated that mitochondria from hearts post-birth had a higher ability to use energy sources like 3-hydroxybutyrate, pyruvate, and glutamate, suggesting shifts in energy metabolism that occur after giving birth.
