In contrast to the single metallothionein (MT)-1 gene of the mouse, the human MT-1 gene family is composed of seven active genes and six pseudogenes. In this study, the expression of mRNA representing the seven active human MT-1 genes was determined in cultured human proximal tubule (HPT) cells under basal conditions and after exposure to the metals Cd2+, Zn2+, Cu2+, Hg2+, Ag2+, and Pb2+. Basal...

To achieve a satisfactory removal efficiency of heavy metal ions from wastewater, silane-functionalized montmorillonite with abundant ligand-binding sites (-NH2) was synthesized as an efficient adsorbent. Ca-montmorillonite (Ca-Mt) was functionalized with 3-aminopropyl triethoxysilane (APTES) to obtain the APTES-Mt products (APTES1.0CEC-Mt, APTES2.0CEC-Mt, APTES3.0CEC-Mt, APTES4.0CEC-Mt) with e...

BACKGROUND Dedicated pediatricians in emergency departments (EDs) may be beneficial, though no previous studies have assessed the related costs and benefits/harms. We aimed to evaluate the net benefits and costs of dedicated emergency pediatricians in a pediatric ED. METHODS Cost-consequences analysis of visits to a pediatric ED of a tertiary hospital. Two pediatric ED Medical Teams (MT) were...

the iranian persian chub is an endemic species of the family cyprinidae known only from few localities in drainages of southern iran. it was originally described in the genus pseudophoxinus as (pseudophoxinus persidis) and then petroleuciscus (as petroleuciscus persidis). in this study, we examined phylogenetic relationships of the iranian persian chubwith other relatives in the family cyprinid...

The influence of metallothionein (MT)(2) on Zn absorption was investigated in MT-null (MT-/-) and normal (MT+/+) mice fed Zn-depleted (ZnD) diets for 7 d and compared with those fed Zn-replete (ZnR) diets in a previous study. Mice were starved for 20 h, then administered an oral gavage of aqueous (65)ZnSO(4) solution at doses of 154, 770 or 1540 nmol of Zn, and the amount transferred into nongu...

We consider Mt/Mt/S-type queueing model with group services. Bounds on the rate of convergence for the queue-length process are obtained. Ordinary Mt/Mt/S queue and Mt/Mt/S type queueing model with group services are studied as examples.
