Cardiomyocyte crosstalk with endothelium modulates cardiac structure, function, and ischemia-reperfusion injury susceptibility through erythropoietin.

Erythropoietin (EPO) exerts non-canonical roles beyond erythropoiesis that are developmentally, structurally, and physiologically relevant for the heart as a paracrine factor. The role for paracrine EPO signalling and cellular crosstalk in the adult is uncertain. Here, we provided novel evidence showing cardiomyocyte restricted loss of function in in adult mice induced hyper-compensatory increases in expression by adjacent cardiac endothelial cells via HIF-2α independent mechanisms.

Novel roles of cardiac-derived erythropoietin in cardiac development and function.

The role of erythropoietin (EPO) has extended beyond hematopoiesis to include cytoprotection, inotropy, and neurogenesis. Extra-renal EPO has been reported for multiple tissue/cell types, but the physiological relevance remains unknown. Although the EPO receptor is expressed by multiple cardiac cell types and human recombinant EPO increases contractility and confers cytoprotection against injury, whether the heart produces physiologically meaningful amounts of EPO in vivo is unclear.

Assessing systolic and diastolic reserves in male and female mice.

Cardiac reserve is a widely used health indicator and prognostic tool. Although it is well established how to assess cardiac reserve clinically, in preclinical models, it is more challenging lacking standardization. Furthermore, although cardiac reserve incorporates both systolic (i.

Enrollment in the Supported Employment Demonstration: An Employment Intervention for Denied Disability Benefits Applicants with a Mental Impairment.

The Supported Employment Demonstration enrolled denied Social Security Disability Benefits applicants with alleged or documented mental impairment into an employment and health intervention. Recruiters attempted to contact 21,003 applicants located near participating community mental health agencies, and enrolled 2960 eligible applicants from November 2017 through March 2019. Among potentially eligible enrollees, 26.

Characteristics of Enrollees in the Supported Employment Demonstration.

Objective: The Supported Employment Demonstration (SED), a multiyear (2016-2022), randomized controlled trial funded by the Social Security Administration, recruited a nontraditional sample of benefits applicants with self-reported or documented mental health conditions who were denied disability benefits and who expressed a desire for employment. This study describes the characteristics of the SED sample at baseline.

Methods: The authors analyzed baseline data from the 2,960 eligible enrollees, including responses to the Composite International Diagnostic Interview, the 12-item Short-Form Health Survey (SF-12), and the Work Disability Functional Assessment Battery (WD-FAB).

Helping People Denied Disability Benefits for a Mental Health Impairment: The Supported Employment Demonstration.

Social Security Administration demonstration projects that are intended to help people receiving disability benefits have increased employment but not the number of exits from disability programs. The Supported Employment Demonstration (SED) is a randomized controlled trial (RCT) of services for individuals with mental health problems before they enter disability programs. The SED aims to provide health, employment, and other support services that help them become self-sufficient and avoid entering disability programs.

Temperature Dependence of Lithium Anode Voiding in Argyrodite Solid-State Batteries.

Void formation at the Li/ceramic electrolyte interface of an all-solid-state battery on discharge results in high local current densities, dendrites on charge, and cell failure. Here, we show that such voiding is reduced at the Li/LiPSCl interface at elevated temperatures, sufficient to increase the critical current before voiding and cell failure from <0.25 mA cm at 25 °C to 0.

Epitheliotropic T-cell lymphoma in 2 half-sibling bontebok.

We diagnosed epitheliotropic T-cell lymphoma of the forestomachs in 2 aged, half-sibling, zoo-managed bontebok (). One bontebok also had mesenteric lymph node and cutaneous involvement. Both animals had a history of chronic abdominal distension and diminished body condition that resulted in euthanasia.

Outbreak of Paranannizziopsis australasiensis Infection in Captive African Bush Vipers (Atheris squamigera).

We report the epidemiological, clinical and pathological features of an outbreak of Paranannizziopsis australasiensis (order Onygenales) in captive African bush vipers (Atheris squamigera) (ABVs) that died suddenly. The snakes had multifocal, raised, white-grey to dark brown discoloured cutaneous patches. Microscopically, all had integumentary lesions characterized by multifocal to coalescent necroheterophilic epidermitis with superficial and intraepidermal fungal elements and bacteria.

Disruption of Physiological Rhythms Persist Following Cessation of Cigarette Smoke Exposure in Mice.

Background: Physiological rhythms in mammals are essential for maintaining health, whereas disruptions may cause or exacerbate disease pathogenesis. As such, our objective was to characterize how cigarette smoke exposure affects physiological rhythms of otherwise healthy mice using telemetry and cosinor analysis.

Methods: Female BALB/c mice were implanted with telemetry devices to measure body temperature, heart rate, systolic blood pressure (SBP), and activity.

Benefits of Multiple Sclerosis Adult Day Program Participation for People with Multiple Sclerosis: A Qualitative Study.

Background: Multiple sclerosis adult day programs (MSADPs) are nonmedical service programs that provide care and support to people with multiple sclerosis (MS) experiencing levels of impairment that interfere with employment and activities of daily living. The purpose of this study was to identify how program participants think MSADPs benefit them.

Methods: We conducted in-depth interviews with 95 people with MS who were MSADP participants.

Applications of a novel radiotelemetry method for the measurement of intrathoracic pressures and physiological rhythms in freely behaving mice.

Techniques to comprehensively evaluate pulmonary function carry a variety of limitations, including the ability to continuously record intrathoracic pressures (ITP), acutely and chronically, in a natural state of freely behaving animals. Measurement of ITP can be used to derive other respiratory parameters, which provide insight to lung health. Our aim was to develop a surgical approach for the placement of a telemetry pressure sensor to measure ITP, providing the ability to chronically measure peak pressure, breath frequency, and timing of the respiratory cycle to facilitate circadian analyses related to breathing patterns.

EVALUATION OF CELL PRESERVATIVES ON THE INTEGRITY OF ATTWATER'S PRAIRIE CHICKEN () WHOLE BLOOD SAMPLES OVER TIME.

The processing of blood samples can be delayed during health assessments of wildlife populations in distant locations. The use of whole blood preservatives may be useful in these situations. However, there is scant information regarding their use in nonmammalian species.

Analysis of Interfacial Effects in All-Solid-State Batteries with Thiophosphate Solid Electrolytes.

All-solid-state batteries (ASSBs) present a promising route toward safe and high-power battery systems in order to meet the future demands in the consumer and automotive market. Composite cathodes are one way to boost the energy density of ASSBs compared to thin-film configurations. In this manuscript, we investigate composites consisting of β-LiPS (β-LPS) solid electrolyte and high-energy Li(NiMnCo)O (NMC622).

Sodium/Na β″ Alumina Interface: Effect of Pressure on Voids.

Three-electrode studies coupled with tomographic imaging of the Na/Na-β″-alumina interface reveal that voids form in the Na metal at the interface on stripping and they accumulate on cycling, leading to increasing interfacial current density, dendrite formation on plating, short circuit, and cell failure. The process occurs above a critical current for stripping (CCS) for a given stack pressure, which sets the upper limit on current density that avoids cell failure, in line with results for the Li/solid-electrolyte interface. The pressure required to avoid cell failure varies linearly with current density, indicating that Na creep rather than diffusion per se dominates Na transport to the interface and that significant pressures are required to prevent cell death, >9 MPa at 2.

An examination of individual responses to ischemic preconditioning and the effect of repeated ischemic preconditioning on cycling performance.

Purpose: To use repeated control trials to measure within-subject variability and assess the existence of responders to ischemic preconditioning (IPC). Secondly, to determine whether repeated IPC can evoke a dosed ergogenic response.

Methods: Twelve aerobically fit individuals each completed three control and three IPC 5-km cycling time trials.

Critical stripping current leads to dendrite formation on plating in lithium anode solid electrolyte cells.

A critical current density on stripping is identified that results in dendrite formation on plating and cell failure. When the stripping current density removes Li from the interface faster than it can be replenished, voids form in the Li at the interface and accumulate on cycling, increasing the local current density at the interface and ultimately leading to dendrite formation on plating, short circuit and cell death. This occurs even when the overall current density is considerably below the threshold for dendrite formation on plating.

Computed tomography porosity and spherical indentation for determining cortical bone millimetre-scale mechanical properties.

The cortex of the femoral neck is a key structural element of the human body, yet there is not a reliable metric for predicting the mechanical properties of the bone in this critical region. This study explored the use of a range of non-destructive metrics to measure femoral neck cortical bone stiffness at the millimetre length scale. A range of testing methods and imaging techniques were assessed for their ability to measure or predict the mechanical properties of cortical bone samples obtained from the femoral neck of hip replacement patients.

COMPARISON OF CIRCULATING IRON, TOTAL IRON BINDING CAPACITY, AND PERCENT TRANSFERRIN SATURATION IN WILD AND CAPTIVE KORI BUSTARDS ( ARDEOTIS KORI).

  The kori bustard ( Ardeotis kori) is one of the largest extant flighted birds and is displayed in zoos primarily in North America and Europe. In captivity, kori bustard diets are primarily based on animal proteins, whereas in the wild these birds eat a wide variety of plants, insects, and small vertebrate prey. The purpose of this study was to compare circulating iron, total iron binding capacity, and percent transferrin saturation levels in apparently healthy wild and captive kori bustards.
