Delipidated proteins from albumin-free liver and heart cytosol obtained from rats sacrificed at the mid-dark or the mid-light phase of the light cycle were assayed for their palmitate-binding capacity. In both tissues a marked variation of this binding capacity was observed from about 3-4 nmol/mg of protein in the mid-light phase of the cycle to about 7-8 nmol/mg of protein in the mid-dark phas...

background: sediments in marine environment have a large capacity in binding with heavy metals; therefore, they are potential pollutants of water resources. the anzali wetland, located in the southern region of the caspian sea, iran, has been consistently threatened by heavy metal pollutants because of urban, agricultural and industrial wastewater inflow. the purpose of this study is to investi...

Mechanisms that control nuclear membrane remodeling are essential to maintain the integrity of nucleus but remain be fully defined. Here, we identify a phosphatidic acid (PA)–binding capacity in envelope (NE)–specific ESCRT, Chm7, budding yeast. Chm7’s interaction with PA-rich membranes is mediated through conserved hydrophobic stretch amino acids, which confers recruitment NE manner independen...

The serum iron concentration and Total Iron Binding Capacity (TIBC) status of 24 patients of oral squamous cell carcinoma (OSCC) were compared with the findings of 13 healthy subjects. OSCC was found to have association with low serum iron level. More patients were found to be with significantly lower iron content in serum (p<0.05). But no association between serum TIBC and increased risk of ca...

Previous reports from South Africa have drawn attention to the heavy iron intake, and to the high frequency of hemosiderin deposition in the liver and other organs of the indigenous Bantu population (1, 2). In addition, observations in different Bantu population groups have demonstrated elevated levels of serum iron and total iron binding capacity in Bantu adults of both sexes. Saturation is ve...

AIMS To investigate the clinical value and practice of reflective testing, a new term to describe the practice of adding on tests when reporting or clinically authorising results. METHODS A consultant medical biochemist collected over a calendar year (2001) copies of clinical biochemistry reports on samples to which he had added on either iron studies (iron, total iron binding capacity (TIBC)...

Cultured monkey kidney cells are shown to possess a cell-surface receptor that binds 5-methyltetrahydro[3',5',7,9-3H4]folic acid (5-methyltetrahydro[3H]folic acid) with high affinity (Kd = 3 nM at 4 degrees C). The cell-surface binding capacity for [3H]folic acid or [3H]methotrexate is equivalent to that for 5-methyltetrahydro[3H]folate, but the Kd values are 0.4 and 20 nM, respectively. These ...

Feeding HMF, an insoluble "high-molecular-weight fraction" from an industrial enzymatic digest of a soy protein isolate, increased the fecal excretion of bile acid concomitant with increased fecal nitrogen. An amino acid analysis revealed that this increased fecal nitrogen could be explained by an increase in the insoluble protein fraction. This suggests the existence of an indigestible protein...

In this research, the generation process of engineered microsphere agarose adsorbent has been explained that has surfaces with different active sites to adsorb protein nanoparticles into the fluidized-bed system. Also, excellent selectivity of protein nanoparticles, high adsorption capacity, and fast equilibrium rate through the eco-friendly polymeric adsorbents were vital aims in here. Hence, ...

BACKGROUND Melasma is a common acquired disorder characterized by symmetric, hyperpigmented patches with an irregular outline, occurring most commonly on the face. It is most prevalent among young to middle-aged women. Although iron overload affects skin pigmentation, effect of iron deficiency on skin is not clear. So, we evaluated serum iron level, ferritin and total iron binding capacity (TIB...
