it is well-known that deficiency or over exposure to various elements has noticeable effects on human health. the effect of an element is determined by several characteristics, including absorption, metabolism, and degree of interaction with physiological processes. iron is an essential element for almost all living organisms as it participates in a wide variety of metabolic processes, includin...

Some decompositions of the three-dimensional sphere and three-dimensional ball into Jordan curves are considered. In particular, it is proved that for every strictly positive real number p ≤ 1 there exists a partition of the unit three-dimensional Euclidean sphere into circles whose radii are equal to p. Let S2 be the unit two-dimensional sphere in the Euclidean space R3 and let S3 be the unit ...

The ring-sheared drop is a containerless system where shear imparted by two contact rings, one rotating and the other stationary. In microgravity, aqueous drops can be studied in air at centimeter scale. Drops of this scale also experimentally on Earth, but effects gravity need to mitigated density matching liquid its surrounding fluid. use silicone oil surrounded an solution allows while retai...

Method Retrospective analysis with colonic between January 2018 - August 2019. Anaemia categorised as – Iron Deficiency non- anaemia. IDA was hypochromic microcytic Patient demographics, tumour location, pre-...

not beginning or completing the vaccination schedule as recommended in the expanded programme on immunization is one of the major reasons for low immunization coverage. it should be studied in detail for remedial action, if the objectives of the epi in iran are to be achieved as stated. generally, lack of knowledge, lack of motivation and obstacles ore the basic categorical reasons for low cove...

We present the Chandra study of the intermediately distant (z = 0.194) cluster of galaxies MS 0839.9+2938. By performing both the projected and deprojected spectral analyses, we find that the gas temperature is approximately constant at about 4 keV in 130 − 444h 70 kpc. In the inner regions, the gas temperature descends towards the center, reaching < ∼ 3 keV in the central 37h 70 kpc. This infe...

Superoxide damages dehydratases that contain catalytic [4Fe-4S](2+) clusters. Aconitases are members of that enzyme family, and previous work showed that most aconitase activity is lost when Escherichia coli is exposed to superoxide stress. More recently it was determined that E. coli synthesizes at least two isozymes of aconitase, AcnA and AcnB. Synthesis of AcnA, the less-abundant enzyme, is ...
