Manubriosternal Morphology of Anthropoid Primates.

Objectives: The purpose of this paper is to examine the proportions of the manubrium and sternebrae across anthropoid primates to explore variation hypothesized to be related to thoracic shape and locomotor specialization, and to determine whether the sternoclavicular joint orientation in hominoids reflects hypothesized differences in shoulder joint positioning relative to the thorax.

Materials And Methods: Metric data and sternoclavicular joint orientation data were collected from calibrated photographs of manubria and sternebrae from a large sample (n = 244) of extant anthropoid primates, as well as a small sample of fossil taxa. Manubriosternal and rib cage metric data were also collected from CT scans of an additional 52 extant anthropoid torsos.

Acetabular orientation, pelvic shape, and the evolution of hominin bipedality.

Hominin pelvic form differs dramatically from that of other primates by having more laterally facing iliac blades, a wider sacrum, and a larger, transversely broad pelvic inlet. The orientation of the acetabulum may also differ, plausibly related to differences in load transmission during upright posture and habitual bipedal locomotion, which may, in turn, affect overall pelvic geometry. We compared acetabular orientation in humans, a phylogenetically broad sample of extant anthropoid primates, and fossil hominins including Australopithecus afarensis (A.

Factors Associated with Pediatric Drowning-Associated Lung Injury.

Objective: To identify risk factors for clinically-important drowning-associated lung injury (ciDALI) in children.

Study Design: This was a cross-sectional study of children (0 through18 years) who presented to 32 pediatric emergency departments (EDs) from 2010 through 2017. We reviewed demographics, comorbidities, prehospital data, chest radiographs reports, and ED course from emergency medical services, medical, and fatality records.

Recurring incursions and dissemination of novel Eurasian-origin H5Nx avian influenza viruses in Atlantic Canada.

Wild birds are important hosts of influenza A viruses (IAVs) and play an important role in their ecology. The emergence of the A/goose/Guangdong/1/1996 H5N1 (Gs/GD) lineage marked a shift in IAV ecology, leading to recurrent outbreaks and mortality in wild birds from 2002 onwards. This lineage has evolved and diversified over time, with a recent important derivative being the 2.

PRMT5-regulated splicing of DNA repair genes drives chemoresistance in breast cancer stem cells.

Breast cancer stem cells (BCSCs) are a rare cell population that is responsible for tumour initiation, metastasis and chemoresistance. Despite this, the mechanism by which BCSCs withstand genotoxic stress is largely unknown. Here, we uncover a pivotal role for the arginine methyltransferase PRMT5 in mediating BCSC chemoresistance by modulating DNA repair efficiency.

The Professional Identity of STEM Faculty as Instructors of Course-based Research Experiences.

The professional identity of scientists has historically been cultivated to value research over teaching, which can undermine initiatives that aim to reform science education. Course-Based Research Experiences (CRE) and the inclusive Research and Education Communities (iREC) are two successful and impactful reform efforts that integrate research and teaching. The aim of this study is to explicate the professional identity of instructors who implement a CRE within an established iREC and to explore how this identity contributes to the success of these programs.

Mechanisms underlying dilated cardiomyopathy associated with FKBP12 deficiency.

Dilated cardiomyopathy (DCM) is a highly prevalent and genetically heterogeneous condition that results in decreased contractility and impaired cardiac function. The FK506-binding protein FKBP12 has been implicated in regulating the ryanodine receptor in skeletal muscle, but its role in cardiac muscle remains unclear. To define the effect of FKBP12 in cardiac function, we generated conditional mouse models of FKBP12 deficiency.

Incidence and Predictors of Adverse Events Among Patients Awaiting Left Atrial Appendage Closure.

Background: There is a paucity of data regarding the optimal timing of left atrial appendage closure (LAAC) and whether scheduling delays increase the risk for adverse outcomes.

Objectives: This study sought to assess the incidence and predictors of adverse events among patients awaiting LAAC.

Methods: This single-center retrospective study assessed all patients who underwent LAAC from January 2017 to March 2020.

Wounds in a correctional facility in Malta: a point prevalence study.

Hard-to-heal (chronic) wounds are a challenge to wound care professionals, a burden to the health service and negatively impact affected individuals' quality of life. They also consume a great deal of healthcare resources globally and are found in all settings, including prisons. Therefore, the evaluation of wound care services is essential in order to develop an awareness of where improvement can be made.

Impact of iron supplementation among anemic voluntary first-time blood donors: Results from the BLOODSAFE pilot trial in Ghana.

Introduction: In sub-Saharan Africa (SSA), an adequate supply of safe blood for transfusion is a major developmental challenge. In Ghana, deferral from blood donation for anemia accounts for nearly half of the ineligible blood donors. We conducted a longitudinal two-arm parallel-group non-inferiority trial to test if iron supplementation among blood donors with iron deficiency (ID) or anemia could increase their hemoglobin levels to near those without ID or anemia.

Enhanced Efficacy of Some Antibiotics in the Presence of Silver Nanoparticles Against Clinical Isolate of Recovered from Cystic Fibrosis Patients.

Introduction: Given the increasing frequency of drug-resistant bacteria and the limited progress in developing new antibiotics, it is necessary to explore new methods of combating microbial infections. Nanoparticles, particularly silver nanoparticles (Ag-NPs), have shown exceptional antibacterial characteristics; however, elevated concentrations of Ag-NPs can produce noticeable levels of toxicity in mammalian cells.

Aim: This study examined the potential synergistic effect of combining a low dosage of Ag-NPs and anti-pseudomonas drugs against (ATCC strain) and eleven clinical isolates from cystic fibrosis patients.

Optimizing Treatment Strategies for Distal Radius Fractures in Osteoporosis: A Comparative Review.

Osteoporosis is a common yet underdiagnosed condition that increases the risk of fractures, contributing to substantial morbidity, mortality, and healthcare costs. Distal radius fractures (DRFs) are some of the most common fractures associated with osteoporosis and often precede more severe fractures. Managing DRFs in patients with osteoporosis can be a challenge due to altered bone quality, which can affect healing and surgical fixation.

Analytical methods for Ir-192 determination and their comparison.

The Centers for Disease Control and Prevention (CDC) Radiation Laboratory's primary mission is to provide laboratory support for an effective and efficient response to public health radiological emergencies. The laboratory has developed methods for several radiological threat agents, including Iridium-192 (Ir-192). Ir-192 can be analyzed via its gamma energy through analytical methods such as High Purity Germanium (HPGe) and its beta energy through Liquid Scintillation Counting (LSC).

Adaptation During the Shift from Entomopathogen to Endosymbiont Is Accompanied by Gene Loss and Intensified Selection.

Fungi have been found to be associated with many insect species, with some species transitioning to reside within insects as symbionts. However, the evolutionary pressures and genomic consequences associated with this transition are not well understood. Pathogenic fungi of the genus Ophiocordyceps have undergone multiple, independent transitions from pathogen to endosymbiont lifestyles, where they reside within the fatty tissues of infected soft-scale insects transgenerationally without killing their hosts.

The impact of neck flexion on ventilation and glottic visualisation in a child with Treacher Collins syndrome.

We report the airway management of an 11-year-old boy with Treacher Collins syndrome. In three instances under general anaesthesia, ventilation via either anaesthesia facemask or supraglottic airway device proved virtually impossible except when the neck was flexed, which runs counter to what is typically observed during routine anaesthetic care. In this report, the impact of neck flexion on the patient's airway is demonstrated with images obtained on videolaryngoscopy and flexible endoscopy.

A β-hydroxybutyrate shunt pathway generates anti-obesity ketone metabolites.

β-Hydroxybutyrate (BHB) is an abundant ketone body. To date, all known pathways of BHB metabolism involve the interconversion of BHB and primary energy intermediates. Here, we identify a previously undescribed BHB secondary metabolic pathway via CNDP2-dependent enzymatic conjugation of BHB and free amino acids.

Dendritic Molecular Baskets for Selective Binding of Toxic Methotrexate.

We describe the preparation, assembly, recognition characteristics, and bioactivity of dendritic basket 6. This novel cavitand has a deep aromatic pocket with three (S)-glutamic acid dendrons at the rim to amplify water solubility and prevent self-association. H NMR spectroscopy, calorimetry (ITC), and mass spectrometry (ESI-MS) measurements validate the formation of an inclusion complex between 6 and anticancer drug methotrexate (MTX) in water (K=9.

Urinary Response to Consuming Plant-Based Meat Alternatives in Persons with Normal Kidney Function: The SWAP-MEAT Pilot Trial.

Background: Consuming excess animal meat may exacerbate kidney disorders, such as urinary stone disease and CKD. Plant-based meat alternatives imitate animal meat and replace animal with vegetable protein, but it is unclear whether eating plant-meat confers similar health benefits as eating whole vegetables. We hypothesized that eating plant-meat when compared with animal meat decreases dietary acid load but increases dietary phosphorus and nitrogen.

Effect of Egg Washing and Hen Age on Cuticle Quality and Bacterial Adherence in Table Eggs.

The cuticle covering the outer surface of an eggshell functions as both a physical and chemical barrier against invading microorganisms. Contamination of eggs by microbial pathogens progresses in four stages: bacterial attachment to the egg surface, penetration through the cuticle and eggshell, multiplication within the underlying membranes, and the final stage of contaminating the egg contents. Therefore, it is important to study bacterial count at the first point of contact, i.
