Sympathetic nerve signaling rewires the tumor microenvironment: a shift in "microenvironmental-ity".

Nerve signaling within the tumor microenvironment (TME) plays a critical role in the initiation, progression, and metastasis of solid tumors. Due to their highly responsive behavior and activation upon injury and cancer onset, this review specifically focuses on how sympathetic nerves rewire the TME. Within tumors, sympathetic nerves closely interact with various TME components, and their combined signaling often shifts tumor-intrinsic physiology toward tumor-supportive phenotypes.

Resource Segmentation: A New Dimension of the Segmentation Hypothesis in Drought Adaptive Strategies and Its Links to Tree Growth Performance.

The segmentation hypothesis, a framework for understanding plant drought adaptive strategy, has long been based on hydraulic resistance and vulnerability. Storage of water and carbohydrate resources is another critical function and shapes plant drought adaption and fitness together with hydraulic efficiency and vulnerability. However, patterns and implications of the interdependency of stored water and carbohydrate resources in the context of the segmentation hypothesis are poorly understood.

Genetic Correlations Among Dental, Mandibular, and Postcranial Dimensions in Rhesus Macaques (Macaca mulatta).

Objectives: Tooth dimensions typically scale with mandibular and postcranial size in primates, although the exact pattern of scaling varies. This study assesses whether correlations by tissue type, anatomical region, or function (mastication or intrasexual competition) are present and could therefore act as evolutionary constraints on tooth-jaw-body size relationships by estimating genetic and phenotypic correlations between dental, mandibular, and postcranial dimensions in rhesus macaques (Macaca mulatta).

Materials And Methods: The teeth, mandibles, and postcrania of 362 adults from the Cayo Santiago skeletal collection were measured.

Addressing cardiovascular health risk factors in American Indian/Alaska Native Children: A narrative review.

Background: Cardiovascular disease (CVD) is common in American Indian/Alaska Native (AI/AN) adults and represents the leading cause of mortality. Risk factors for CVD in AI/AN adults are well-described, and a growing body of evidence reports the inequitable prevalence of factors associated with the development of CVD in AI/AN children, including obesity, physical inactivity, and diabetes mellitus (DM).

Objective: This article organizes and summarizes the evidence describing CVD risk factors in AI/AN children, discusses the social drivers of health impacting these risks, and highlights several programs that have demonstrated effectiveness in improving AI/AN child health.

Environmental contributions to cognitive development: The role of cognitive stimulation.

Early environmental experiences influence children's cognitive and neural development. In particular, cognitive stimulation, defined as environmental inputs that engage the senses and provide learning opportunities for children, fosters acquisition of knowledge across various cognitive domains. Low levels of cognitive stimulation in early life may restrict learning opportunities, contributing to lasting consequences for neural development and later academic and occupational achievement.

Medial and lateral vestibulospinal projections to the cervical spinal cord of the squirrel monkey.

Introduction: The brainstem vestibular nuclei neurons receive synaptic inputs from inner ear acceleration-sensing hair cells, cerebellar output neurons, and ascending signals from spinal proprioceptive-related neurons. The lateral (LVST) and medial (MVST) vestibulospinal (VS) tracts convey their coded signals to the spinal circuits to rapidly counter externally imposed perturbations to facilitate stability and provide a framework for self-generated head movements.

Methods: The present study describes the morphological characteristics of intraaxonally recorded and labeled VS neurons monosynaptically connected to the 8th nerve.

Case report: FGF4L1 retrogene insertion is lacking in the tall dachshund phenotype.

Two retrogene insertions, FGF4L1 (formerly 18-FGF4, colloquially CDPA) and FGF4L2 (formerly 12-FGF4, colloquially CDDY), have recently been discovered as determinants of short leg phenotype in dogs. This case study is comprised of a family of standard wirehaired dachshunds in which the dogs lacking the FGF4L1 gene exhibit a tall phenotype. The tall phenotype in the dachshunds of this report precludes the dog's working function of den work.

Noise-induced hearing loss enhances Ca-dependent spontaneous bursting activity in lateral cochlear efferents.

Exposure to loud and/or prolonged noise damages cochlear hair cells and triggers downstream changes in synaptic and electrical activity in multiple brain regions, resulting in hearing loss and altered speech comprehension. It remains unclear however whether or not noise exposure also compromises the cochlear efferent system, a feedback pathway in the brain that fine-tunes hearing sensitivity in the cochlea. We examined the effects of noise-induced hearing loss on the spontaneous action potential (AP) firing pattern in mouse lateral olivocochlear (LOC) neurons.

Developmental axon diameter growth of central nervous system axons does not depend on ensheathment or myelination by oligodendrocytes.

Myelination facilitates the rapid conduction of action potentials along axons. In the central nervous system (CNS), myelinated axons vary over 100-fold in diameter, with conduction speed scaling linearly with increasing diameter. Axon diameter and myelination are closely interlinked, with axon diameter exerting a strong influence on myelination.

Calochortus tolmiei Hook. & Arn., a bulbous monocot with cat's ear flowers in the angiosperm family Liliaceae, is a perennial herb native to northern California, Oregon, and Washington.

Attendance of Underserved Populations at Field-Based Health Services Events: Application of Quasi-Experimental Methods that Accommodate the COVID-19 Pandemic.

The COVID-19 pandemic disrupted the ability to receive health care services. Field-based health services became a logistically feasible alternative to medical center-based care. We compared two different field-based approaches to the delivery of SARS-CoV-2 testing and health education services for Latine communities using a quasi-experimental design that included propensity score matching to accommodate the challenges posed to research by the pandemic.

Leveraging the predictive power of a 3D in vitro vascularization screening assay for hydrogel-based tissue-engineered periosteum allograft healing.

A common strategy for promoting bone allograft healing is the design of tissue-engineered periosteum (TEP) to orchestrate host-tissue infiltration. However, evaluating requires costly and time-consuming in vivo studies. Therefore, in vitro assays are necessary to expedite TEP designs.

Outpatient surgical institutions in the rural United States: Trends from 2010 to 2020.

Background: The volume and proportion of surgeries occurring in outpatient settings has increased. However, the growth and distribution of outpatient surgical institutions, namely ambulatory surgery centers (ASCs) and hospital-based outpatient surgical departments (HOPDs), remains understudied in rural areas.

Methods: We used descriptive statistics and a multivariate logistic regression to assess the growth and distribution of ASCs and HOPDs in rural areas from 2010 to 2020, leveraging the Area Health Resources Files and American Community Survey.

Comparison of Postoperative Antibiotic Protocols for Pediatric Complicated Appendicitis: A Western Pediatric Surgery Research Consortium Study.

Background: There is no consensus on the appropriate duration of postoperative antibiotics for complicated appendicitis in children. Commonly used antibiotic endpoints include normalization of white blood cell count (WBC) or completion of a minimum number of prespecified treatment days. We compared clinical outcomes resulting from varying postoperative antibiotic protocols for complicated appendicitis in children.

The Quality of Veterans Healthcare Administration Cardiovascular Care.

A total of 9 million veterans receive care in a unique healthcare system, the Veterans Healthcare Administration (VHA), with nearly 50% reporting at least one cardiovascular disease. Despite evidence for high quality of health care in the VHA, more veteran care is being moved to the non-VHA community. An assumption of this shift in care is that the quality of non-VHA care is at least comparable to VHA care.
