The advantages of point-of-care HIV testing are decreased transit time, faster overall turnaround time, and high frequency with which patients receive their test results.
This was unexpected (and I'll spare you details), but there was a definite correlation between ACV consumption and, well, let's call it decreased transit time.
These include increased luminal osmolarity (osmotic diarrhea), increased electrolytes secretion (secretory diarrhea), decreased electrolytes absorption, and deranged intestinal motility causing a decreased transit time [ 26].
Recently, studies have shown that this fermented milk significantly decreased transit time in young and elderly healthy adults [ 9- 13] and in constipation-predominant IBS patients [ 14].
Whole grain foods are important sources of dietary fibre and may decrease the risk of colorectal cancer by increasing stool bulk, diluting faecal carcinogens, and decreasing transit time, thus reducing the contact between carcinogens and the lining of the colorectum.
Insoluble fibre in grains increases the bulk of luminal contents, thereby diluting potential carcinogens and promoters in the colon and decreasing transit time, and, consequently, reduces the exposure of the colonic epithelium to harmful compounds (Slavin et al, 1999).
In rats microinjected with vehicle into the CSF or IP, the average colonic transit time was 322 ± 8 min. As demonstrated in Fig. 1, 0.03 nmol, 0.3 nmol and 3 nmol/5 μl ghrelin injected ICV dose-dependently decreased transit time by 24%, 34%and43%3% respectively in conscious fed rats.
Despite the multiplicity of aetiologies, the four major mechanisms responsible for the pathophysiology in water and electrolytes transport are (i) increased luminal osmolarity (osmotic diarrhoea), (ii) increased electrolytes secretion (secretory diarrhoea), (iii) decreased electrolytes absorption, and (iv) deranged intestinal motility causing a decreased transit time [ 12].
16 In the case of diffusion limitations within the athletic population, the limitation does not seem to derive from a clinical issue with the alveolar capillary barrier, but rather from a decreased transit time of the erythrocyte across the pulmonary capillary.
