Testosterone has short- and long-term roles in regulating neuronal function. Here, we show rapid intracellular androgen receptor-independent effects of testosterone on intracellular Ca2+ in neuroblastoma cells. We identified testosterone-induced Ca2+ signals that began primarily at the neurite tip, followed by propagation towards the nucleus, which was then repeated to create an oscillatory pat...

Neurons containing the calcium-binding proteins, calbindin or parvalbumin, were studied by immunohistochemistry in the superficial dorsal horn of the rat spinal cord. Calbindin-containing cells were found in laminae I, II and III, being more abundant in laminae I and II. Some of the neurons in lamina I containing calbindin projected to the supraspinal area. Parvalbumin-containing neurons were m...

Neural circuits and behavior are shaped during developmental phases of maximal plasticity known as sensitive or critical periods. Neural correlates of sensory critical periods have been identified, but their roles remain unclear. Factors that define critical periods in sensorimotor circuits and behavior are not known. Birdsong learning in the zebra finch occurs during a sensitive period similar...

Abstract Objectives Parvalbumin (PV) is the primary allergen found in fish and highly conserved. According to some studies, patients with allergy are allergic only one species of but tolerant others; however, underlying mechanism has not been identified. Materials Methods The cross-reactivity these seven parvalbumins based on turbot PV-treated mice was determined using BALB/c mouse RBL-2H3 cell...

A previous study has shown that acrylonitrile (ACN) has a long half-life in rainbow trout muscle and that [14C]ACN appears to be bound to a 10,000-Da protein in muscle. The labeled protein was purified from muscle of trout exposed to [14C]ACN, separated on 20% SDS-PAGE, and digested for amino acid analysis and sequence analysis. These studies indicated that the labeled protein was the Ca(2+)-bi...

Gap junctions are common between cortical GABAergic interneurons but little is known about their quantitative distribution along dendritic profiles. Here, we provide direct morphological evidence that parvalbumin-containing GABAergic neurons in layer 2/3 of the cat visual cortex form dense and far-ranging networks through dendritic gap junctions. Gap junction-coupled networks of parvalbumin neu...

Cognitive deficits and negative symptoms are important therapeutic targets for schizophrenia and autism disorders. Although reduction of phase-locked gamma oscillation has been suggested to be a result of reduced parvalbumin-immunoreactive (putatively, GABAergic) neurons, no direct correlations between these have been established in these disorders. In the present study, we investigated such re...

We examined the distribution of parvalbumin in the pigeon thymus by light and electron microscopic immunohistochemistry. Tissues were also examined by conventional electron microscopy to determine the ultrastructure of immunoreactive cells. Parvalbumin immunoreaction was located in epithelial cells of the cortex, which formed dense mesh-like structures. Parvalbumin-positive epithelial cells wer...

A hallmark of schizophrenia pathophysiology is the dysfunction of cortical inhibitory GABA neurons expressing parvalbumin, which are essential for coordinating neuronal synchrony during various sensory and cognitive tasks. The high metabolic requirements of these fast-spiking cells may render them susceptible to redox dysregulation and oxidative stress. Using mice carrying a genetic redox imbal...

Abstract Objectives The main objective was to gain more knowledge on exposure bioaerosols in the processing area board fishing trawlers. Methods Exposure sampling carried out during work shifts when fish five deep-sea trawlers (trawlers 1–5). samples were collected from 64 fishermen breathing zone and stationary stations (1–5). Trawlers 2, 3, 4 old ships, not originally built for of catch. 1 5 ...
