question:
We investigated the role of hydrogen sulphide (H(2)S) in intracellular pH (pH(i)) regulation in vascular smooth muscle cells and its contribution on vasodilation. NaHS, a H(2)S donor, decreased pH(i) in a concentration-dependent manner ranging from 10 microM to 1mM. Neither inhibition of the Na(+)/H(+) exchanger with 5-(N-ethyl-N-isopropyl) amiloride, (EIPA, 10 microM), nor plasmalemmal Ca(2+)-ATPase with CdCl(2) (20nM) alters the effect of NaHS on pH(i). Blockade of the Cl(-)/HCO3- exchanger with 4,4'-diisothiocyanatostilbene-2,2'-disulfonic acid (DIDS) significantly attenuated the pH(i) lowering effect of NaHS. Moreover, NaHS significantly increased the activity of Cl(-)/HCO3- exchanger when measured with NH(4)Cl prepulse method. DIDS attenuated the vasorelaxation induced by NaHS whereas EIPA and CdCl(2) did not cause any change. In conclusion, H(2)S induced intracellular acidification via activation of Cl(-)/HCO3- exchanger, which is, at least partially, responsible for H(2)S-mediated vasorelaxation.
answer:
Hydrogen sulphide regulates intracellular pH in vascular smooth muscle cells.

question:
Superresolution Optical Fluctuation Imaging (SOFI) as initially demonstrated allows for a resolution enhancement in imaging by a factor of square-root of two. Here, we demonstrate how to increase the resolution of SOFI images by re-weighting the Optical Transfer Function (OTF). Furthermore, we demonstrate how cross-cumulants can be exploited to obtain a fair approximation of the underlying Point-Spread Function. We show a two-fold increase of resolution (over the diffraction limit) of near-infrared quantum dot labeled tubulin-network of 3T3 fibroblasts.
answer:
Achieving increased resolution and more pixels with Superresolution Optical Fluctuation Imaging (SOFI)

question:
Little is known about the changes in white blood cells and platelets in children with falciparum malaria in endemic areas. We measured the white cell count (WCC) and platelets of 230 healthy children from the community, 1369 children admitted to hospital with symptomatic malaria, and 1461 children with other medical conditions. Children with malaria had a higher WCC compared with community controls, and leucocytosis was strongly associated with younger age, deep breathing, severe anaemia, thrombocytopenia and death. The WCC was not associated with a positive blood culture. In children with malaria, high lymphocyte and low monocyte counts were independently associated with mortality. A platelet count of less than 150 x 109/l was found in 56.7% of children with malaria, and was associated with age, prostration and parasite density, but not with bleeding problems or mortality. The mean platelet volume was also higher in children with malaria compared with other medical conditions. This may reflect early release from the bone marrow in response to peripheral platelet destruction. Thus, leucocytosis was associated with both severity and mortality in children with falciparum malaria, irrespective of bacteraemia, whereas thrombocytopenia, although very common, was not associated with adverse outcome.
answer:
Changes in white blood cells and platelets in children with falciparum malaria: relationship to disease outcome.
