Many phenotypic traits have a polygenic genetic basis, making it challenging to learn their genetic architectures and predict individual phenotypes. One promising avenue to resolve the genetic basis of complex traits is through evolve-and-resequence experiments, in which laboratory populations are exposed to some selective pressure and trait-contributing loci are identified by extreme frequency changes over the course of the experiment. However, small laboratory populations will experience substantial random genetic drift, and it is difficult to determine whether selection played a role in a given allele frequency change.

Objectives: Deep Brain Stimulation (DBS) is an effective, yet underused therapy for people living with Parkinson's disease (PD) in whom tremor, motor fluctuations and/or dyskinesia are not satisfactorily controlled by oral medical therapy. Fear of vascular complications related to the operative procedure remains a strong reason for both the referrer and patient reluctance. We review the incidence of vascular complications in the first 600 patients with Parkinson's disease treated at our centre by a single neurologist/neurosurgical team.

Article Synopsis
  • Olduvai protein domains, linked to the NBPF gene family, show significant expansion in humans and correlate with brain size and neuron numbers in primates, as well as human brain variations like microcephaly and macrocephaly.
  • Research indicates that overexpression of the Olduvai gene may lead to downregulation of mitochondrial functions, particularly affecting the electron transport chain and NADH dehydrogenase activity, based on transcriptome and proteome analyses.
  • The findings suggest that this downregulation could slow development processes in primates, especially humans, potentially resulting in an extended neurogenic period that allows for the production of more neurons and a larger brain size.

Article Synopsis
  • - Mind-wandering is a common mental activity with unique experiences for each person, but previous studies mainly focused on group data rather than individual experiences due to limited sampling.
  • - Through extensive testing of three participants using functional MRI, the researchers found consistent links between mind-wandering and activation of the default mode network (DMN), but variations in timing and other brain networks involved were specific to each individual.
  • - The study highlighted the differences in brain connectivity patterns associated with mind-wandering, suggesting that personalized models are necessary instead of relying on general models derived from larger groups, and emphasizing the importance of studying individual differences in neuroscience.

Article Synopsis
  • The study addresses the lack of research on teaching menstrual care skills, particularly for individuals with autism spectrum disorder and other disabilities, aiming to evaluate existing literature.
  • A literature review following PRISMA guidelines identified only 7 relevant studies over 40 years, mostly lacking rigor according to What Works Clearinghouse standards, with only one study achieving the highest rating.
  • The findings emphasize the challenges in developing effective interventions for menstrual care and aim to guide future researchers in conducting high-quality studies while being respectful and effective in their programming.

Introduction: Pain management for trauma in the extreme environment is vital for both casualty comfort and aiding safe extrication. However, adequate pain management in a resource-limited environment can be challenging and is often limited. We conducted a scoping review of the use of regional anesthesia in the prehospital environment, evaluating which regional anesthetic procedure was performed for various indications, their efficacy, and the type of healthcare provider delivering the anesthetic.

Mind-wandering is a frequent, daily mental activity, experienced in unique ways in each person. Yet neuroimaging evidence relating mind-wandering to brain activity, for example in the default mode network (DMN), has relied on population-rather than individual-based inferences due to limited within-individual sampling. Here, three densely-sampled individuals each reported hundreds of mind-wandering episodes while undergoing multi-session functional magnetic resonance imaging.

Research resources like transgenic animals and antibodies are the workhorses of biomedicine, enabling investigators to relatively easily study specific disease conditions. As key biological resources, transgenic animals and antibodies are often validated, maintained, and distributed from university based stock centers. As these centers heavily rely largely on grant funding, it is critical that they are cited by investigators so that usage can be tracked.

We estimated norms and percentiles for the Pediatric Emotional Distress Scale (PEDS) in order to enhance its utility as a screening tool for emotional and behavioral distress following a major. The PEDS was administered to a nationally representative sample of parents of children ages 5-12 from all 50 states ( = 1,570). Approximately 15% of the parents reported a trauma/stress in the past 12 months.

Tree nuts, a low-moisture food, are typically perceived as being a low risk for foodborne illness. In the past five decades, the consumption of tree nuts (dry, soaked, or as nut-based dairy analogs [NBDA]) has increased along with corresponding foodborne illness outbreaks and recalls associated with these products. We developed an online survey to assess tree nut handling practices of U.

Emergency departments (EDs) are dynamic, complex, and demanding environments. Introducing changes that lead to improvements in EDs can be challenging owing to the high staff turnover and mix, high patient volume with different needs, and being the front door to the hospital for the sickest patients. Quality improvement is a methodology applied routinely in EDs to instigate change to improve several outcomes such as waiting times, time to definitive treatment, and patient safety.

Olduvai protein domains (formerly DUF1220) show the greatest human-specific increase in copy number of any coding region in the genome and are highly correlated with human brain evolution and cognitive disease. The majority of human copies are found within four NBPF genes organized in a variable number of a tandemly arranged three-domain blocks called Olduvai triplets. Here we show that these human-specific Olduvai domains are posttranslationally processed by the furin protease, with a cleavage site occurring once at each triplet.
