BACKGROUND The anterior-medial thalamus (AMT), which is associated with memory processing, is severely affected by Alzheimer's disease pathology and, when damaged, can be the sole cause of dementia. OBJECTIVE To assess the frequency of magnetic resonance imaging (MRI) hyperintensities affecting the AMT, and their relationship with sudden cognitive decline. METHODS 205 consecutive participan...

This paper addresses issues encountered in the use of an Auditory Masking Threshold (AMT) for speech enhancement and proposes an algorithm to improve AMT estimation for broadband noise sources. We determined that while AMT estimation is fairly accurate, and hence an enhancement scheme based on AMT can suppress audible noise to a greater extent for low frequency colored noise sources, the algori...

The effect of electrolytes and nonelectrolytes on the micellar behavior of amitriptyline (AMT), an amphiphilic drug, has been investigated using cloud point (CP) and dye solubilization techniques. The critical micelle concentration (cmc) of AMT determined by the Wilhelmy plate method was about 40mM in the presence of 10mM sodium phosphate, and it reduced to about 20mM in the presence of 500mM s...

Purpose. To describe a surgical technique using amniotic membrane transplant (AMT) with fibrin glue (FG) for treating smaller corneal perforations more practically and appropriately filling the defect. Method. A patient with noninfectious central corneal perforation, in 1 mm in diameter, was treated with FG-assisted AMT-plug. An AMT was folded in on itself twice by using FG then a small piece o...

AZT (zidovudine, 3'-azido-3'-deoxythymidine), although metabolized primarily to AZT-glucuronide, is also metabolized to 3'-amino-3'-deoxythmidine (AMT) by reduction of the azide to an amine. The formation of the myelotoxic metabolite AMT has not been well characterized, but inhibition of AMT formation would be of therapeutic benefit. The aim of this study was to identify compounds that inhibit ...

Question 1. (1) Write f(x) = amx m + am−1xm−1 + · · ·+ a0. Then F = f(T ) = amT + am−1Tm−1 + · · ·+a0I. Since T is upper triangular, (T )ii = T k ii for all positive k and i ∈ {1, . . . , n}. Hence Fii = amT m ii + am−1T m−1 ii + · · ·+ a0 = f(Tii). (2) TF = Tf(T ) = T (amT m+am−1Tm−1+ · · ·+a0I) = amT+am−1T+ · · ·+a0T = (amT m + am−1Tm−1 + · · ·+ a0I)T = f(T )T = FT . (3) Since T is upper tria...

The photochemical aminomethyltrimethyl psoralen (AMT), in conjunction with UV A light (UVA), has been shown to inactivate human immunodeficiency virus-1 and model viruses in platelet suspensions under conditions that have only a minimal effect on in vitro platelet properties. A rabbit ear bleeding time technique was used to assess the hemostatic effectiveness of human platelet suspensions treat...

BACKGROUND To investigate the effectiveness of amniotic membrane transplantation (AMT) on improving the outcomes of trabeculectomy in primary open-angle glaucoma (POAG). METHODS Fifty-nine eyes affected by primary open-angle glaucoma were enrolled in this prospective randomized study. Thirty-two eyes underwent amnion-shielded trabeculectomy (study group) and 27 eyes underwent trabeculectomy w...

Transcranial magnetic studies typically rely on measures of active and resting motor threshold (i.e. AMT, RMT). Previous work has demonstrated that adaptive threshold hunting approaches are efficient for estimating RMT. To date, no study has compared motor threshold estimation approaches for measures of AMT, yet this measure is fundamental in transcranial magnetic stimulation (TMS) studies that...
