Background and Objective: Beta-2 Microglobulin (β2M) is a middle molecular weight uremic toxin. Lack of β2M removal leads to β2M accumulation and amyloidosis in hemodialysis patients. The present research aims to determine the relationship between β2M and inflammatory factors, such as C-reactive protein (CRP), albumin, and high-density lipoprotein (HDL) in hemodialysis patie...

beta-thalassemia major (β-tm) is a chronic, genetic and hematological disorder. children and teenagers with chronic physical illnesses exemplified by thalassemia are vulnerable to emotional and behavioral problems. the aim of this study was to evaluate mental health and its related factors among young patients with beta-thalassemia major.in this cross-sectional observational descriptive-analyti...

Recall that a continuous function $fcolon Xto Y$ between Tychonoff spaces is proper if and only if the Stone extension $f^{beta}colon beta Xtobeta Y$ takes remainder to remainder, in the sense that $f^{beta}[beta X-X]subseteq beta Y-Y$. We introduce the notion of ``taking remainder to remainder" to frames, and, using it, we define a frame homomorphism $hcolon Lto M$ to be $beta$-proper, $lambd...

background: thalassemia represents a serious health problem in iran because of its heterogeneous frequency and the existing endogamy system. it is an inherited blood disease characterized by the under production of normal hemoglobin, the oxygen-carrying protein in red blood cells. materials and methods: in this study, serum antioxidants including selenium (se), zinc (zn) and copper (cu) were me...

background beta-thalassemia patients receive blood products from blood transfusion centers repeatedly. blood transfusion can transmit cytomegalovirus (cmv) and toxoplasma gondii. the aim of this study was serological evaluation of these two infectious agents in thalassemia patients. materials and methods in a cross-sectional study, the enzymelinked immunosorbent assay (elisa) testing was perfor...

Replacement reactions ('pseudomorphism') commonly occur in Nature under a large range of conditions (T 25 to >600 degrees C; P 1 to >5 kbar). Whilst mineral replacement reactions are often assumed to proceed by solid-state diffusion of the metal ions through the mineral, many actually proceed via a coupled dissolution and reprecipitation (CDR) mechanism. In such cases, a starting mineral is dis...

In this study, incorporation of iron ion-doped natrolite nanozeolite, multi-wall carbon nanotubes into chitosan-coated glassy carbon electrode for the simultaneous determination of ascorbic acid, epinephrine, uric acid and tyrosine is studied. The results show that the combination of multi-wall carbon nanotubes and iron ion-doped natrolite zeolite causes a dramatic enhancement in the sensitivit...

Let $(X, \tau)$ and $(Y, \sigma)$ be topological spaces in which no separation axioms are assumed, unless explicitly stated if $\mathcal{I}$ is an ideal on $X$.Given a multifunction $F\colon (X, \tau)\rightarrow (Y, \sigma)$, $\alpha,\beta$ operators \tau)$, $\theta,\delta$ proper $X$. We introduce study upper lower $(\alpha, \beta,\theta,\delta,\mathcal{I})$-continuous multifunctions.A said to...

A PEBAX-nano zeolite X mixed matrix membrane was fabricated and operationally characterized using single gas (CO2) permeation. X-ray diffraction (XRD) analysis was used to study the arrangement of polymer chains of mixed matrix membrane. The membranes were characterized by scanning electron microscopy (SEM) to study cross-sectional morphology. The single gas permeability were carried...
