Needs of human resource professionals in implicit bias and disability inclusion training: A focus group study.

Background: Research investigating the implicit bias of employers towards individuals with disabilities emphasizes the importance of increased attention to implicit bias in the workplace. Previous research supports the use of trainings to promote awareness and education of implicit and explicit bias toward people with disabilities among employers.

Objective: The purpose of the current study was to better understand employers' stigmatizing attitudes toward individuals with disabilities and develop effective strategies to increase awareness and knowledge related to these negative attitudes.

PTH hypersecretion triggered by a GABA and Ca-sensing receptor heterocomplex in hyperparathyroidism.

Molecular mechanisms mediating tonic secretion of parathyroid hormone (PTH) in response to hypocalcaemia and hyperparathyroidism (HPT) are unclear. Here we demonstrate increased heterocomplex formation between the calcium-sensing receptor (CaSR) and metabotropic γ-aminobutyric acid (GABA) B receptor (GABAR) in hyperplastic parathyroid glands (PTGs) of patients with primary and secondary HPT. Targeted ablation of GABAR or glutamic acid decarboxylase 1 and 2 in PTGs produces hypocalcaemia and hypoparathyroidism, and prevents PTH hypersecretion in PTGs cultured from mouse models of hereditary HPT and dietary calcium-deficiency.

A Guide to Single-Cell Transcriptomics in Adult Rodent Brain: The Medium Spiny Neuron Transcriptome Revisited.

Recent advances in single-cell technologies are paving the way to a comprehensive understanding of the cellular complexity in the brain. Protocols for single-cell transcriptomics combine a variety of sophisticated methods for the purpose of isolating the heavily interconnected and heterogeneous neuronal cell types in a relatively intact and healthy state. The emphasis of single-cell transcriptome studies has thus far been on comparing library generation and sequencing techniques that enable measurement of the minute amounts of starting material from a single cell.

Calcium-sensing receptor (CaSR) as a novel target for ischemic neuroprotection.

Object: Ischemic brain injury is the leading cause for death and long-term disability in patients who suffer cardiac arrest and embolic stroke. Excitotoxicity and subsequent Ca(2+)-overload lead to ischemic neuron death. We explore a novel mechanism concerning the role of the excitatory extracellular calcium-sensing receptor (CaSR) in the induction of ischemic brain injury.

Sex and age modify biochemical and skeletal manifestations of chronic hyperparathyroidism by altering target organ responses to Ca2+ and parathyroid hormone in mice.

We studied mice with or without heterozygous deletion of the Casr in the parathyroid gland (PTG) [(PTG) CaSR(+/-)] to delineate effects of age and sex on manifestations of hyperparathyroidism (HPT). In control mice, aging induced a left-shift in the Ca(2+) /parathyroid hormone (PTH) set point accompanied by increased PTG CaSR expression along with lowered serum Ca(2+) and mildly increased PTH levels, suggesting adaptive responses of PTGs to aging-induced changes in mineral homeostasis. The aging effects on Ca(2+) /PTH set point and CaSR expression were significantly blunted in (PTG) CaSR(+/-) mice, who showed instead progressively elevated PTH levels with age, especially in 12-month-old females.

Impairments in fast axonal transport and motor neuron deficits in transgenic mice expressing familial Alzheimer's disease-linked mutant presenilin 1.

Presenilins (PS) play a central role in gamma-secretase-mediated processing of beta-amyloid precursor protein (APP) and numerous type I transmembrane proteins. Expression of mutant PS1 variants causes familial forms of Alzheimer's disease (FAD). In cultured mammalian cells that express FAD-linked PS1 variants, the intracellular trafficking of several type 1 membrane proteins is altered.

Service patterns related to successful employment outcomes of persons with traumatic brain injury in vocational rehabilitation.

This study analyzed the Rehabilitation Services Administration (RSA) case service report (RSA-911) data for fiscal year 2004 to examine effects of demographic characteristics, work disincentives, and vocational rehabilitation services patterns on employment outcomes of persons with traumatic brain injuries (TBI). The results indicated that European Americans (53%) had appreciably higher competitive employment rates than Native American (50%), Asian Americans (44%), African Americans (42%), and Hispanic/Latino Americans (41%). Clients without co-occurring psychiatric disabilities had a higher employment rate (51%) than those with psychiatric disabilities (45%).

The integrated stress response prevents demyelination by protecting oligodendrocytes against immune-mediated damage.

In response to ER stress, the pancreatic endoplasmic reticulum kinase (PERK) coordinates an adaptive program known as the integrated stress response (ISR) by phosphorylating the alpha subunit of eukaryotic translation initiation factor 2 (eIF2alpha). IFN-gamma, which activates the ER stress response in oligodendrocytes, is believed to play a critical role in the immune-mediated CNS disorder multiple sclerosis (MS) and its mouse model, experimental autoimmune encephalomyelitis (EAE). Here we report that CNS delivery of IFN-gamma before EAE onset ameliorated the disease course and prevented demyelination, axonal damage, and oligodendrocyte loss.

Immunoglobulins and complement in the skin of rhesus monkeys immunized with x-irradiated cercariae of Schistosoma japonicum.

Skin sections of rhesus monkeys immunized with X-irradiated Schistosoma japonicum cercariae were stained by an unlabeled antibody enzyme method for the detection of IgG, IgM, IgA, IgE, and C3. While all of them could be found in the skin lesions, their distribution patterns varied with time and reactions. In whealing reaginic reactions, IgE appeared prominent, having an affinity to the mast cells.

Immunoglobulin E, mast cells, and eosinophils in the skin of rhesus monkeys immunized with x-irradiated cercariae of Schistosoma japonicum.

Immunoglobulin E (IgE), mast cells, and eosinophils in the skin of rhesus monkeys immunized with highly X-irradiated cercariae of Schistosoma japonicum were studied. IgE was stained by the unlabeled antibody enzyme method and was found on mast cells. Before challenge, mast cells were found only in the dermis.
