‎let $r$ be a $*$-prime ring with center‎ ‎$z(r)$‎, ‎$d$ a non-zero $(sigma,tau)$-derivation of $r$ with associated‎ ‎automorphisms $sigma$ and $tau$ of $r$‎, ‎such that $sigma$‎, ‎$tau$‎ ‎and $d$ commute with $'*'$‎. ‎suppose that $u$ is an ideal of $r$ such that $u^*=u$‎, ‎and $c_{sigma,tau}={cin‎ ‎r~|~csigma(x)=tau(x)c~mbox{for~all}~xin r}.$ in the present paper‎, ‎it is shown that...

BACKGROUND The pathologic substrates of frontotemporal dementia (FTD) are difficult to predict in vivo. OBJECTIVE To determine whether different pathologic substrates of FTD have distinct patterns of regional atrophy on magnetic resonance imaging (MRI). DESIGN Retrospective case study. SETTING The Institute of Neurology, University College London, and the Institute of Psychiatry, King's C...

A bstract Direct CP asymmetry in semi-leptonic τ decays is an intriguing hint for new physics beyond the standard model. We investigate $$ {\tau}^{-}\to {K}_S^0{\pi}^{-}{\nu}_{\tau } τ − → K S 0 </mml...

objective(s):alzheimer&apos;s disease (ad) is the most common age-related neurodegenerative disorder. one of the hallmarks of ad is an abnormal accumulation of fibril forms of tau protein which is known as a microtubule associated protein. in this regard, inhibition of tau aggregation has been documented to be a potent therapeutic approach in ad and tauopathies. unfortunately, the available syn...

objective(s):breast cancer is an important leading cause of death from cancer. stathmin and tau proteins are regulators of cell motility, and their overexpression is associated with the progression and bad prognosis of breast cancer. memantine, an n-methyl-d-aspartate (nmda) receptor antagonist, is the potential inhibitor of tau protein in neurons. this study determines the effect of memantine ...

tau is one of several types of microtubule-associated proteins (maps), responsible for the assembly and stability of microtubule networks that is present only in neurons and predominantly localized in axons which its functions are tightly regulated by phosphorylation. via as yet unknown mechanisms, tau becomes hyperphosphorylated and accompanies with neuronal degeneration, loss of synapses, abe...

We benefit from a recent lattice determination of the full set vector, axial and tensor form factors for ${\mathrm{\ensuremath{\Lambda}}}_{b}\ensuremath{\rightarrow}{\mathrm{\ensuremath{\Lambda}}}_{c}^{*}(2595)\ensuremath{\tau}{\overline{\ensuremath{\nu}}}_{\ensuremath{\tau}}$ ${\mathrm{\ensuremath{\Lambda}}}_{c}^{*}(2625)\ensuremath{\tau}{\overline{\ensuremath{\nu}}}_{\ensuremath{\tau}}$ semil...

BACKGROUND Cognitive remediation therapy (CRT) effectively reduces neurocognitive impairment in patients with schizophrenia, but few studies have used structural neuroimaging methods to assess its neuroanatomical effects. We investigated these effects, as well as the association between changes in cortical volume and neurocognitive performance. METHOD Between August 2013 and September 2016, w...

BACKGROUND We sought to examine the association of levels of total tau (t-tau) and phosphorylated tau 181 (p-tau181) protein with brain morphology in mild cognitive impairment, as defined by the concept of aging-associated cognitive decline (AACD) and Alzheimer disease. METHODS Twenty-three participants with AACD, 16 with Alzheimer disease and 15 healthy controls underwent magnetic resonance ...

a topoframe, denoted by $l_{ tau}$,  is a pair $(l, tau)$ consisting of a frame $l$ and a subframe $ tau $ all of whose elements are complementary elements in$l$. in this paper, we define and study the notions of a$tau $-real-continuous function on a frame $l$ and the set of realcontinuous functions $mathcal{r}l_tau $ as an $f$-ring.we show that $mathcal{r}l_{ tau}$is actually a generalization ...
