Correlations of neuronal oscillations in different brain regions are closely related to a variety of brain functions. The delta and theta oscillations in the olfactory bulb (OB), coupled with respiration rhythm, could play important roles in olfactory tasks. The correlations between the two OBs, however, are largely unknown. By simultaneously recording local field potentials from the OBs, we fo...

Searles Lake is a salt-saturated, alkaline brine unusually rich in the toxic element arsenic. Arsenic speciation changed from arsenate [As(V)] to arsenite [As(III)] with sediment depth. Incubated anoxic sediment slurries displayed dissimilatory As(V)-reductase activity that was markedly stimulated by H2 or sulfide, whereas aerobic slurries had rapid As(III)-oxidase activity. An anaerobic, extre...

abstract aims: lead is emerged as one of the most hazardous elements, existing in the air and soil, which can create irreparable outcomes in the human body due to its highly severe damages. the aim of this study was to determine the relationship between lead level and the respiratory diseases in tiran & karvan region, iran. instrument & methods: the research methodology was analytical based on ...

Organophosphorus pesticides have been used in some cases for suicidal attempts. Such poison can affect plasma cholinesterase activity. The case was a 47-year-old man hospitalized due to suicide attempt with swallowing agricultural poison. The patient, diagnosed with major depressive disorder (MDD), underwent treatment with electroconvulsive therapy (ECT). At the first ECT session, the patient d...

Described by Jean Chevaillier in 1967, autogenic drainage is an airway clearance technique that is widely used throughout Europe. The echnique is characterised by breathing control, where the individual adjusts the rate, depth and location of respiration in order to clear the hest of secretions independently. This paper describes the technique, based on the work of Chevaillier, offering a physi...

Biofeedback involves the monitoring and use of physiologic information to teach patients to modify specific physiologic functions. Common modalities for biofeedback include surface electromyography, respiration rate and depth, skin surface temperature, cardiovascular reactivity, and electrodermal response. Clinical biofeedback therapy broadly involves either the direct feedback learning model o...

Northern ecosystems are a major sink for atmospheric CO2 and contain much of the world’s soil organic carbon (SOC) that is potentially reactive to near-term climate change. We introduce a simple terrestrial carbon flux (TCF) model driven by satellite remote sensing inputs from the Moderate Resolution Imaging Spectroradiometer (MODIS) and the Advanced Microwave Scanning Radiometer for EOS (AMSR-...

The net export of organic matter from the surface ocean and its respiration at depth create vertical gradients in nutrient and oxygen availability that play a primary role in structuring marine ecosystems. Changes in the properties of this 'biological pump' have been hypothesized to account for important shifts in marine ecosystem structure, including the Cambrian explosion. However, the influe...
