#1
Laura J Buchholz, Paul R King, Laura O Wray
Rates of disordered eating may be higher among women veterans than civilians, and are associated with co-occurring mental health (MH) conditions, such as depression, post-traumatic stress disorder (PTSD), and alcohol misuse. Although evidence suggests that these conditions are common in primary care settings, limited research has examined symptoms of disordered eating among women veterans in primary care. This study used a cross-sectional design to examine rates and MH correlates of disordered eating among women veterans treated in a primary care setting...

High mobility group box-1 (HMGB1) acts as a proinflammatory molecule once released into the extracellular space and inhibition of HMGB1 signaling has been reported be neuroprotective in neurodegenerative diseases. Besides, chronic cerebral hypoperfusion (CCH) causes cognitive impairment in neurodegenerative diseases. Here we tested the protective role of HMGB1 inhibition using anti-HMGB1 neutralizing antibody (Ab) against CCH in rats after bilateral common carotid artery occlusion (2VO). 169 male Sprague-Dawley rats underwent 2VO or sham operation...

Congestive heart failure (CHF) is a prevalent disease (especially among the elderly) with high mortality and morbidity rates. The pathological hallmark of CHF is a loss of cardiomyocytes leading to cardiac fibrosis and dysfunctional cardiac remodeling, which culminates in organ failure. Endothelial progenitor cells (EPCs) are bone marrow-derived cells that contribute to maintenance of the integrity of endothelial wall and protect ischemic myocardium through forming new blood vessels (vasculogenesis) or proliferation of pre-existing vasculature (angiogenesis)...

Although food-hoarding animals benefit plant seeds by generating predation pressure on granivorous insects, we lack experimental evidence of whether the tripartite interactions maintain a mutualistic relationship between the third trophic level and primary producers. Relying on the behavior of shelling, Siberian chipmunks (Tamias sibiricus) selectively consumed weevil larvae infested in acorns of Mongolian oak (Quercus mongolica) but chose the non-infested acorns to scatter-hoard. Shelling not only reduced volatile emission from acorns but also decreased cache loss to pilferers, weevil larvae and fungi, allowing T...

Extracellular forces transmitted through the cytoskeleton can deform the cell nucleus. Large nuclear deformation increases the risk of disrupting the nuclear envelope's integrity and causing DNA damage. Mechanical stability of the nucleus defines its capability of maintaining nuclear shape by minimizing nuclear deformation and recovering strain when deformed. Understanding the deformation and recovery behavior of the nucleus requires characterization of nuclear viscoelastic properties. Here, we quantified the decoupled viscoelastic parameters of the cell membrane, cytoskeleton, and the nucleus...

Vasogenic cerebral edema formation after blood brain barrier (BBB) damage aggravates the devastating consequences of intracerebral hemorrhage (ICH). The present study aims to probe into a therapeutic method on BBB preservation after ICH with a glycogen synthase kinase-3β (GSK-3β) inhibitor, lithium. Intrastriatal infusion of semicoagulated autologous whole blood or sham surgery was performed on male Sprague-Dawley (SD) rats (n = 208).Experimental animals received administration of 4,6-disubstitutedpyrrolo-pyrimidine (TWS119), lithium alone or in combination with a phosphatidylinositol 3-kinase inhibitor, wortmannin, after ICH...

Currently available pharmacotherapies for treating alcohol use disorder (AUD) suffer from deleterious side effects and are not efficacious in diverse populations. Clinical and preclinical studies provide evidence that the Kcnq family of genes that encode KV 7 channels influence alcohol intake and dependence. KV 7 channels are a class of slowly activating voltage-dependent K+ channels that regulate neuronal excitability. Studies indicate that the KV 7 channel positive modulator retigabine can decrease dopaminergic neuron firing, alter dopamine (DA) release, and reduce alcohol intake in heavy drinking rodents...

A number of mineral fibers represent a health hazard because they are classified as cancer-causing chemical/physical toxicants upon (chronic) dust inhalation. Although in the last decades they have been the subject of intensive multidisciplinary investigations, the mechanisms by which mineral fibers induce toxic and pathogenic adverse effects on human health and environment are not yet fully understood. The major intricacy of the biological approach that prevents the design of a conclusive shared model of behavior of mineral fibers in a biological system stems from their very nature with intrinsic variability in chemical, molecular, structural and morphometric parameters, biodurability and surface reactivity...

BACKGROUND: Pain is a major non motor symptom that contributes to impaired quality of life in PD. However, its mechanism is unknown. OBJECTIVES AND METHODS: We sought to identify the pain phenotypes and parallel changes in spinal integration of peripheral stimuli in a rat model of PD induced by lesions of SN dopamine neurons, using behavioral plantar and von Frey tests as well as electrophysiology of the dorsal horn. RESULTS: We show that dopamine depletion by 6-OHDA induced hypersensitivity to mechanical and thermal stimuli...

Ethanol intoxication (EI) is a frequent comorbidity of TBI, but the impact of EI on TBI pathogenic cascades and prognosis is unclear: although clinical evidence suggests that EI may have neuroprotective effects, experimental support is, to date, inconclusive. We aimed at elucidating the impact of EI on TBI-associated neurological deficits, signaling pathways and pathogenic cascades, in order to identify new modifiers of TBI pathophysiology. We have shown that ethanol administration (5g/Kg) before trauma enhances behavioral recovery in a weight-drop TBI model; neuronal survival in the injured somatosensory cortex was enhanced by EI...

PURPOSE OF REVIEW: To describe models of integrated and co-located care for opioid use disorder (OUD), hepatitis C (HCV), and HIV. RECENT FINDINGS: The design and scale-up of multidisciplinary care models that engage, retain, and treat individuals with HIV, HCV, and OUD are critical to preventing continued spread of HIV and HCV. We identified 17 models within primary care (N = 3), HIV specialty care (N = 5), opioid treatment programs (N = 6), transitional clinics (N = 2), and community-based harm reduction programs (N = 1), as well as two emerging models...

Rationale: Pluripotent stem cells (PSCs) are being investigated as a cell source for regenerative medicine since they provide an infinitive pool of cells that are able to differentiate towards every cell type of the body. One possible therapeutic application involves the use of these cells to treat myocardial infarction (MI), a condition where billions of cardiomyocytes (CMs) are lost. Although several protocols have been developed to differentiate PSCs towards CMs, none of these provide a completely pure population, thereby still posing a risk for neoplastic teratoma formation...

Multidrug resistance (MDR) poses a great challenge to cancer therapy. It is difficult to inhibit the growth of MDR cancer due to its chemoresistance. Furthermore, MDR cancers are more likely to metastasize, causing a high mortality among cancer patients. In this study, a nanomedicine RGD-NPVs@MNPs/DOX was developed by encapsulating melanin nanoparticles (MNPs) and doxorubicin (DOX) inside RGD peptide (c(RGDyC))-modified nanoscale platelet vesicles (RGD-NPVs) to efficiently inhibit the growth and metastasis of drug-resistant tumors via a cancer cells and tumor vasculature dual-targeting strategy...

Purpose: A vast literature finds that low self-control is associated with a myriad of antisocial behaviors. Consequently, increasing attention has focused on the causes of low self-control. While criminologists have directed significant attention to studying its social causes, fewer studies have considered its neural bases. Methods: We add to this nascent body of research by using data collected on an at-risk sample of adolescents participating in the ongoing Michigan Longitudinal Study...

Genetically modified mice are used as models for a variety of human behavioral conditions. However, behavioral phenotyping can be a major bottleneck in mouse genetics because many of the classic protocols are too long and/or are vulnerable to unaccountable sources of variance, leading to inconsistent results between centers. We developed a home-cage approach using a Chora feeder that is controlled by-and sends data to-software. In this approach, mice are tested in the standard cages in which they are held for husbandry, which removes confounding variables such as the stress induced by out-of-cage testing...

Despite the advances in pain management, achieving optimal pain control in hospice and palliative care is challenging. Patient/caregiver's lack of pain management knowledge, poor pain reporting, and poor adherence to pain management regimens are all associated with inadequate pain control. The purpose of this integrated review is to examine behavioral interventions designed for patients and caregivers to improve pain control in hospice and palliative care settings. Ten studies were identified through a database search...

One of the most fundamental behaviors in all the organisms, in order to achieve a satiated state and internal energy homeostasis is feeding. The action of feeding in any being whether be it any vertebrate or an invertebrate involves the perception of the external environment along with the gamut of decision making processes to eat or to not eat. The feeding decision along with chemosensation through gustation and olfaction leads to intake of food with proper nutrient balance along with avoidance of bitter and toxic substances...

A small neuronal subpopulation in the medial nucleus of the amygdala (MeA), expressing the Kiss1 gene, is now considered an important mediator that integrates socio-sexual behavior and odor information in order to modulate the Hypothalamic-Pituitary-Gonadal (HPG) axis. Previous studies demonstrated that exogenous kisspeptin administration or selective activation of Kiss1-expressing neurons in the MeA modulates the onset of puberty, LH secretion and sexual behavior. These functions are supported by the known MeA neuronal connections...

Feeding strategies are dependent on multi-modal sensory processing, that integrates visual, chemosensory, and mechanoreceptive cues. In many fish species, local environments and food availability dramatically influence the evolution of sensory and morphological traits that underlie feeding. The Mexican cavefish, Astyanax mexicanus, have developed robust changes in sensory-dependent behaviors, but the impact on prey detection and feeding behavior is not known. In the absence of eyes, cavefish have evolved enhanced sensitivity of the lateral line, comprised of mechanosensory organs that sense water flow and detect prey...
