The short-term exposure to microcystin-LR (MC-LR, one of the most common and toxic variants generated by toxigenic cyanobacteria) induced gut dysfunction such as generation of reactive oxygen species, cell erosion and deficient intestinal absorption of nutrients.
However, the large variation in serum fentanyl concentrations indicates unpredictable or possibly deficient drug absorption from transdermal patches when applied according to the manufacturer's instructions for humans.
Thus, we believe that the lack of an effective n-3 attenuation of the dexamethasone-induced muscle atrophy was not related to deficient intestinal absorption of n-3.
This disease is characterized by an impaired function of the immune system, growth retardation and skin alterations as a result of a deficient gastrointestinal zinc absorption [ 5].
In the elderly, the symptoms of vitamin B12 deficiency caused by deficient diets and/or digestive and/or absorption problems can be nonspecific, making a diagnosis of deficiency more difficult.
Of note, DGAT1 deficiency in apolipoprotein E-deficient mice decreases cholesterol absorption, blood cholesterol, and foam cell formation, resulting in protection from atherosclerosis [ 29].
Theseauthors reported a reduced effect of metformin on AMP kinase phosphorylation in Oct1-deficient mouse hepatocytes and poor absorption of metformin in Oct1-deficient mice.
5, 19 The significant negative correlation we observed between the change in serum zinc level after supplementation and the baseline serum zinc level suggests that zinc-deficient individuals had greater absorption of zinc than individuals with higher zinc levels at the baseline.
These data are consistent with a biological mechanism of increased lead absorption among iron deficient children.
Furthermore, the dye was potently reduced in cells expressing NQO1 but failed to change absorption in NQO1 deficient cells such as CHO cells.
