at present, when a clinical diagnosis of parkinson’s disease (pd) is made, serious damage has already been done to nerve cells of the substantia nigra pars compacta. the diagnosis of pd in its earlier stages, before this irreversible damage, would be of enormous benefit for future treatment strategies designed to slow or halt the progression of this disease that possibly prevents accumulation o...

during the period of 1984-1995, nine young patients were admitted to shiraz university hospitals with a chief complaint of abdominal mass, weight loss and chronic diarrhea. clinically, these cases were diagnosed as intestinal tuberculosis or lymphoma. laparotomy revealed a huge mass involving the upper small intestine. histologic sections showed diffuse infiltration of the intestinal wall with ...

objective :t o investigate the hematologic indices of mothers in non-immune hydrops fetalis pregnancies and identify the possible causative role of alpha-thalassemia among them. material and methods: from 2005 to 2007, 11386 hydrops fetalis cases in three major obstetric hospitals affiliated to tehran university of medical sciences were recorded. indirect coombs test and hematologic indices of ...

alpha-fetoprotein (afp), a serum glycoprotein belonging to the onco-developmental proteins group, serves as a marker both in cancer research and in studies concerning fetal development and fetal pathophysiology. monoclonal anti-afp antibodies are essential reagents in developing appropriate techniques for measurement of this protein. in this study, in order to produce anti-afp monoclonal antibo...

Let $A(G)$ be the adjacency matrix and $D(G)$ diagonal of vertex degrees a simple connected graph $G$. Nikiforov defined $A_{\alpha}(G)$ convex combinations as $A_{\alpha}(G)=\alpha D(G)+(1-\alpha)A(G)$, for $0\leq \alpha\leq 1$. If $ \rho_{1}\geq \rho_{2}\geq \dots \geq \rho_{n}$ are eigenvalues (which we call $\alpha$-adjacency $G$), \alpha $-adjacency energy $G$ is $E^{A_{\alpha}}(G)=\sum_{i...

We consider the punctured plane with volume density $|x|^\alpha$ and perimeter $|x|^\beta$. show that centred balls are uniquely isoperimetric for indices $(\alpha,\beta)$ which satisfy conditions $\alpha-\beta+1>0$, $\alpha\leq 2\beta$ $\alpha(\beta+1)\leq\beta^2$ except in case $\alpha=\beta=0$ corresponds to classical inequality.
