A closer look at how symmetry constraints and the spin-orbit coupling shape the electronic structure of Bi(111).

Fully relativistic density-functional-theory calculations of Bi(111) thin films are analyzed to revisit their two metallic surface-states branches. We first contrast these metallic branches with surface states arising at gaps in the valence band opened by the spin-orbit coupling (SOC). We find that the two metallic branches alongΓM‾do not overlap with the bulk band at the zone boundary,.

An uncommon occurrence of bicavitary effusion due to mast cell neoplasia in a 12-year-old mixed breed dog.

A case of bicavitary effusion affecting a 12-year-old female spayed mixed breed dog that was presented to Tuskegee University College of Veterinary Medicine's Emergency Service for abdominal distension and vomiting. Upon physical exam, the patient exhibited signs of pain and sensitivity to touch and pain on abdominal palpation with a positive fluid wave. The patient also had dull mentation and increased respiratory effort with an abdominal component.

African and Native American foodways and resilience: From 1619 to COVID-19.

The COVID-19 pandemic is flooding and splitting "efficiency" fault lines in today's industrialized food system. It also exploits centuries of historical traumas, White supremacy, and systemic racism to kill non-White people at triple the rates of Whites. In 1619, an English ship landed on the shores of the Powhatan confederacy, or, as the English called it, Point Comfort, Virginia.

T-cell lymphoma-associated hemophagocytic syndrome in an American Pit Bull Terrier.

A 3-y-old, intact female, American Pit Bull Terrier was presented because of acute onset of anorexia and a large subcutaneous submandibular mass that had been present for 3 wk. The submandibular mass, 2 engorged black-legged ticks on the dorsum of the neck, pyrexia, and icterus were seen on physical examination. Abnormal laboratory test results included a positive antibody test, severe thrombocytopenia, mild nonregenerative anemia, hyperbilirubinemia, and elevated liver enzyme activities.

SARS-CoV-2 infection in the Syrian hamster model causes inflammation as well as type I interferon dysregulation in both respiratory and non-respiratory tissues including the heart and kidney.

COVID-19 (coronavirus disease 2019) caused by SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) infection is a disease affecting several organ systems. A model that captures all clinical symptoms of COVID-19 as well as long-haulers disease is needed. We investigated the host responses associated with infection in several major organ systems including the respiratory tract, the heart, and the kidneys after SARS-CoV-2 infection in Syrian hamsters.

Multi-Institutional, Multidisciplinary Study of the Impact of Course-Based Research Experiences.

Numerous national reports have called for reforming laboratory courses so that all students experience the research process. In response, many course-based research experiences (CREs) have been developed and implemented. Research on the impact of these CREs suggests that student benefits can be similar to those of traditional apprentice-model research experiences.

Neuroprotective effects of resveratrol in Alzheimer disease pathology.

Alzheimer's disease is a chronic neurodegenerative disorder characterized by a progressive loss of cognitive and behavioral abilities. Extracellular senile plaques and intracellular neurofibrillary tangles are hallmarks of AD. Researchers aim to analyze the molecular mechanisms underlying AD pathogenesis; however, the therapeutic options available to treat this disease are inadequate.

Assessing needs and assets for building a regional network infrastructure to reduce cancer related health disparities.

Significant cancer health disparities exist in the United States and Puerto Rico. While numerous initiatives have been implemented to reduce cancer disparities, regional coordination of these efforts between institutions is often limited. To address cancer health disparities nation-wide, a series of regional transdisciplinary networks through the Geographic Management Program (GMaP) and the Minority Biospecimen/Biobanking Geographic Management Program (BMaP) were established in six regions across the country.

Differentiation of human mesenchymal stem cell spheroids under microgravity conditions.

To develop and characterize a novel cell culture method for the generation of undifferentiated and differentiated human mesenchymal stem cell 3D structures, we utilized the RWV system with a gelatin-based scaffold. 3 × 10(6) cells generated homogeneous spheroids and maximum spheroid loading was accomplished after 3 days of culture. Spheroids cultured in undifferentiated spheroids of 3 and 10 days retained expression of CD44, without expression of differentiation markers.

Recruiting and retaining minorities in nursing education.

Increasing nursing education opportunities for individuals from minority and/or disadvantaged backgrounds is the purpose of this project. Activities included the implementation of programs to enhance preentry preparation, retention, cultural competence and financial support. Intense recruitment strategies were targeted to seniors from high schools in Macon County and contiguous counties, the counties where most students currently enrolled at Tuskegee reside.

Race and healthcare disparities: overcoming vulnerablity.

The paper summarizes recently published data and recommendations about healthcare disparities experienced by African Americans who have Medicare or other healthcare coverage. Against this background the paper addresses the ethics of such disparities and how disadvantages of vulnerable populations like African Americans are typically maintained in decision making about how to respond to such disparities. Considering how to respond to disparities reveals much that vulnerable populations would bring to the policy-making table, if they can also be heard when they get there.

Medical observations of malingering in Iraqi enemy prisoners of war during Operation Desert Storm.

The authors, who were at the Al Khanjar enemy prisoner of war (EPW) collection point along the Saudi Arabian-Kuwaiti frontier during Operation Desert Storm, furnish two accounts of malingering and deliberate, manipulative attempts at "conning the doctors" by Iraqi EPWs of the Republican Guard Corps. To some extent, malingering and conning of the doctors with faked illness or complaint expended time and other valuable resources that could have been directed toward EPW patient care and treatment with genuine medical bases.

Erythrocyte cation content and sodium transport in Siberian huskies.

Adult mixed-breed dogs and Siberian Huskies were used to study erythrocyte cation and water contents, as well as sodium transport kinetics. Erythrocyte sodium, potassium, and water contents, as well as sodium efflux and influx kinetics, were measured. Lithium efflux studies were also performed, because previous studies reported involvement of this ion in sodium transport kinetics.

Monensin-induced cation movements in bovine erythrocytes.

Monensin is a carboxylic ionophore that has been observed to increase cation permeability across the membrane of several cell types. Additionally, it is used commercially as an anticoccidial agent and has been found to increase feed efficiency in cattle. The objectives of these experiments were to determine the ability of monensin to stimulate cation (Na and K) transport across the bovine erythrocyte membrane and determine the effects of anion substitution on the action of the compound.

LHRH - Induced ovulation and fertility of anestrous goats.

Seventeen female mature anestrous does were used to study the effect of luteinizing hormone-releasing hormone (LHRH) on ovulation (Experiment I) and on fertility rate and blood estrogen/progesterone concentrations (Experiment II). Laparotomy after day 8 of treatment with a single injection of LHRH (300 ug) and estradiol cypionate (0.2 mg/kg) revealed evidence of ovulation in two out of three and a developed follicle in the third.

Extracellular Antigens from Listeria monocytogenes I. Purification and Resolution of Hemolytic and Lipolytic Antigens from Culture Filtrates of Listeria monocytogenes.

Two antigens were purified from culture filtrates of Listeria monocytogenes 7973 by the following procedure: (i) acid precipitation with 4 n HCl at pH 3.7, (ii) Sephadex G-75 column fractionation, (iii) diethylaminoethyl-Sephadex A50 batchwise adsorption, and (iv) rechromatography on Sephadex G-75. This procedure resulted in the resolution of two distinct antigens.
