The crossover from the semiclassical transport to quantum Hall effect is studied by examining a two-dimensional electron system in an AlGaAs/GaAs heterostructure. By probing the magneto-oscillations, it is shown that the semiclassical Shubnikov-de Haas (SdH) formulation can be valid even when the minima of the longitudinal resistivity approach zero. The extension of the applicable range of the ...

Healthy living is mainly seen as a product of good genetics and holistic healthcare in the United States, but a growing field of research is also attributing well-being to social determinants of health (SDH), which are the compounded effects that arise from the concentration or lack of social capital. The Affordable Care Act (ACA) was enacted to promote the overall health of the country and its...

TRAP1 is a mitochondrial chaperone highly expressed in many tumor types; it inhibits respiratory complex II, down-modulating its succinate dehydrogenase (SDH) enzymatic activity. SDH inhibition in turn leads to a pseudohypoxic state caused by succinate-dependent HIF1α stabilization and promotes neoplastic growth. Here we report that TRAP1 inhibition of SDH also shields cells from oxidative insu...

Transmission electron microscopy was used to study the cellular morphologies of a wild-type Rhizobium meliloti strain (L5-30), a nitrogen fixation-ineffective (Fix-) succinate dehydrogenase mutant (Sdh-) strain, and a Fix+ Sdh+ revertant strain within alfalfa nodules and after free-living growth in a minimal medium containing 27 mM mannitol plus 20 mM succinate. The results showed a requirement...

The appearance of a subdural hematoma (SDH) following spinal anesthesia is a serious and rare complication which mandates prompt diagnosis, although the treatment modalities are not well codified. Patients with post-dural puncture headache (PDPH) non-responsive to conservative measures and/or those patients with a change of the character of the headache should be considered seriously. In sympto...

Distribution of lactate dehydrogenase (LDH) and succinic dehydrogenase (SDH) in the ovary of mice treated with two chronic doses of sodium fluoride (NaF), for five days, in drinking water. LDH histochemical reactivity was observed following Hess et al., (1958) technique and SDH histochemical reactivity was obtained using the method of Nachlas et al., (1957). A decreasing trend of enzyme reactiv...

This Article acknowledges the necessity of including social determinants health (SDH) data in healthcare planning and treatment but highlights lack regulation around collection SDH potential for violating consumers’ basic rights to be treated equally, protected from discrimination, have their privacy respected. The analyzes different approaches U.S. EU proffers global application GDPR plus huma...

background health is a complex phenomenon and equity as a basic human right an integral part of constitutions in almost all countries in the world. in republic of macedonia (rm), tuberculosis (tb) is clustered regionally and in certain ethnic groups. the main objective of this study was to analyze social determinants of health (sdh) and equity in access to healthcare services for tb patients in...

Neurons in the trigeminal subnucleus caudalis (Vc) and spinal cord dorsal horn (SDH) play important roles in modulating and relaying pain signals to the higher centers of the central nervous system (CNS). Morphologically, many aspects including a laminated structure, cytoarchitecture and cellular elements in these two central regions are very similar [1 ,2, 3, 4] . Most nociceptive afferents wi...
