Krypton-85 dissolved in 0.9% NaCl was injected into the femoral artery of man; fi particles were measured over the skin of the eras. Cutaneous mean blood flow was calculated using the integral equation of Zierler based on the mean transit time analysis of clearance curves recorded from the cutaneous tissue; these calculations gave estimates which were only about one-fifth those obtained by othe...

Cation composition of frog smooth muscle cells was investigated. Fresh stomach muscle rings resembled skeletal muscle, but marked Na gain and K loss followed immersion. Mean Na (49.8-79.7 mM/kg tissue) and K (61.8-80.1 mM/kg tissue) varied between batches, but were stable for long periods in vitro. Exchange of 6-30 mM Na/kg tissue with (22)Na was extremely slow and distinct. Extracellular water...

The regulation of iron supply to plasma was studied in male rate. Repeated exchange transfusions were first carried out with plasma from iron-deficient or iron-loaded animals. There was no recognizable effect on the amount of iron entering the plasma as evidenced by plasma iron concentration or iron absorption by recipient animals. In other studies, iron compounds having different tissue distri...

This model focuses on the behavior of capillary-tissue fluid exchange system when the diameter of the capillary is less than that of red cell. In vivo and in vitro observations indicate that the width of the gap between the red cell and the vessel wall is generally small compared to the radius of the capillary for a single file flow of red cell in narrow vessel, particularly if the vessel diame...

Recent reports have suggested the involvement of gut microbiota in the progression of colorectal cancer (CRC). We utilized pyrosequencing based analysis of 16S rRNA genes to determine the overall structure of microbiota in patients with colorectal cancer and healthy controls; we investigated microbiota of the intestinal lumen, the cancerous tissue and matched noncancerous normal tissue. Moreove...

in this paper, we will review the foreign exchange market and will try to extract an exchange market pressure and an intervention index for iran by following the weymark (1995) approach to evaluate the central bank of iran’s exchange rate policy during 1368:q1 to 1391:q3. the estimation method employed, is the econometric technique known in the literature as the two-stage least squares (2sls).t...
