The generation of germline cells from human induced pluripotent stem cells (hiPSCs) represents a milestone toward in vitro gametogenesis. Methods to recapitulate germline development beyond primordial germ cells in vitro have relied on long-term cell culture, such as 3-dimensional organoid co-culture for ~four months. Using a pipeline with highly parallelized screening, this study identifies combinations of TFs that directly and rapidly convert hiPSCs to induced oogonia-like cells (iOLCs).

Because hummingbirds are small and have an expensive mode of locomotion, they have constrained energy budgets. Torpor is used to buffer against these energetic challenges, but its frequency and duration vary. We measured lipid content, metabolic rates and torpor use in two species of migrating hummingbirds, calliope () and rufous hummingbirds () at a stopover site.

Article Synopsis
  • Caudal blocks are a pediatric anesthesia technique used to manage pain after circumcision; this study aimed to compare the duration of the block when using a high-volume, low-concentration (HVLC) local anesthetic with and without the addition of clonidine.
  • The study included 129 children aged 0-3 years and measured the effectiveness of pain relief based on how long patients waited before needing additional acetaminophen; no significant differences were found between the clonidine and no-clonidine groups regarding pain management or emergence agitation.
  • Overall, the addition of clonidine did not significantly improve the outcomes of HVLC caudal blocks for children undergoing circumcision.

Background: The high incidence of dysphagia after acute stroke is likely the result of cumulative effects of the stroke and pre-stroke brain health. While cerebral small vessel disease (cSVD) is recognized as a marker of compromised brain health, it's unclear which neuroanatomical pathologies of cSVD impact post-stroke dysphagia. We assessed the relation between cSVD pathologies, i.

Article Synopsis
  • The study compares the efficacy of the quadratus lumborum block (QLB) and the pericapsular nerve group (PENG) block for pain management after total hip arthroplasty (THA), focusing on postoperative opioid consumption and pain scores.
  • 106 subjects were randomized into two groups: QLB (51 patients) and PENG (50 patients), with results showing that QLB patients used significantly less opioids at 36, 48, 60, and 72 hours post-surgery.
  • Both techniques provided effective pain relief without impacting motor function, but QLB resulted in lower pain scores with movement and reduced opioid use compared to PENG+LFC blocks.

  • - The study investigated the effects of fluoxetine, a selective serotonin reuptake inhibitor, on epilepsy development in female rats that underwent status epilepticus induced by lithium-pilocarpine.
  • - Although fluoxetine did not change brain glucose metabolism or seizure frequency, it reduced neuroinflammation in the hippocampus by 22.6%.
  • - The researchers found a correlation between glucose metabolism in the hippocampus shortly after status epilepticus and seizure frequency later on, suggesting that FDG-PET could serve as a biomarker for epilepsy progression.

Chronic alcohol (ethanol) use is increasing in the United States and has been linked to numerous health issues in multiple organ systems including neurological dysfunction and diseases. Ethanol toxicity is mainly driven by the metabolite acetaldehyde, which is generated through three pathways: alcohol dehydrogenase (ADH2), catalase (CAT), and cytochrome P450 2E1 (CYP2E1). ADH2, while the main ethanol clearance pathway in the liver, is not expressed in the mammalian brain, resulting in CAT and CYP2E1 driving local metabolism of ethanol in the central nervous system.

In-season management of anterior shoulder instability in athletes is a complex problem. Athletes often wish to play through their current season, though recurrent instability rates are high, particularly in contact sports. Athletes are generally considered safe to return to play when they are relatively pain-free, and their strength and range of motion match the uninjured extremity.

Objectives: Telemedicine has become a widely accepted alternative to face-to-face patient encounters. Although there have been several peer-reviewed journal articles on incorporating telemedicine into the medical school curriculum, particularly during the COVID-19 pandemic, assessments of the effectiveness of remote supervision of medical students have not been reported. This prospective cohort study of student subjects using observational survey data evaluated the efficacy of telemedicine as an educational resource by comparing learning outcomes between osteopathic medical students receiving direct (physically present) supervision with a group who received remote (telemedicine) supervision by clinical faculty within a post-acute/long-term care (PA/LTC) setting.

Hypometabolism arising from active metabolic suppression occurs in several contexts among endotherms, particularly during heterothermic states such as torpor. However, observed Q ≈ 1 for avian resting metabolic rate within the thermoneutral zone, values far below the Q = 2-3 expected on the basis of Arrhenius effects, suggests hypometabolism also plays a role in birds' thermoregulation at environmental temperatures approaching or exceeding normothermic body temperature (T). We evaluated the occurrence of hypometabolism during heat exposure among birds by re-analysing literature data to quantify changes in T and resting metabolic rate (RMR) near the upper boundary of the thermoneutral zone, at air temperatures (T) between the inflection above which T increases above normothermic levels (T) and the upper critical limit of thermoneutrality (T).
