BACKGROUND AND PURPOSE To examine the neurophysiological basis for the pronounced differences in hyperactivity and impulsiveness that distinguish the predominantly inattentive type of attention-deficit/hyperactivity disorder (ADHD-PI) from the combined type of the disorder (ADHD-C). METHODS Event-related brain responses to a go/no-go test of inhibitory control were measured with functional ma...
There is debate regarding the integrity of semantic memory in dementia of the Alzheimer type (DAT). One view argues that DAT is associated with a breakdown in semantic memory; the other argues that DAT is associated with predominantly preserved semantic memory and a breakdown in retrieval. The classic release from proactive interference (RPI) paradigm was used to shed light on this debate. Indi...
در قسمت اول این تحقیق یکسری برهمکنش های بین مولکولی با استفاده از محاسبات nmr مورد بررسی قرار گرفته اند. اثر استخلاف های مختلف در موقعیت های متا و پارا بر داده های nmr در کمپلکس های پیریدن استخلاف دار و هیدروژن فلوئورید مورد مطالعه قرار گرفت. مشخص شد که بین داده های nmr و قدرت الکترون دهندگی استخلاف ها یک همبستگی معناداری وجود دارد. از داده های aim نیز می توان برای پیش بینی داده های nmr استفاد...
599 PRIMARY INSOMNIA (PI) IS A PREVALENT AND SERIOUS HEALTH CONCERN CHARACTERIZED BY COMPLAINTS OF CHRONIC NOCTURNAL SLEEP disturbance and associated daytime impairment occurring in the absence of any contributory medical or psychiatric condition. Current evidence suggests that 1% to 2%1,2 of the general population and approximately 20%3,4 of patients encountered in clinical settings suffer for...
Structures are reported here for eight further substituted N-aryl-2-chloronicotinamides, 2-ClC(5)H(3)NCONHC(6)H(4)X-4'. When X = H, compound (I) (C(12)H(9)ClN(2)O), the molecules are linked into sheets by N-H...N, C-H...pi(pyridyl) and C-H...pi(arene) hydrogen bonds. For X = CH(3), compound (II) (C(13)H(11)ClN(2)O, triclinic P1 with Z' = 2), the molecules are linked into sheets by N-H...O, C-H....
Page 4 PSG Request for Datamining Abstract Parkinson’s disease (PD) has many paradoxes. For example, although smoking is highly associated with cancer and cardiovascular disease, smoking is associated with a much lower risk of PD (which itself is associated with a lower occurrence of cardiovascular disease). Whereas the apolipoprotein E ε4 allele is associated with higher risk of Alzheimer’s di...
BACKGROUND Standard first-line combination antiretroviral treatment (cART) against human immunodeficiency virus 1 (HIV-1) contains either a nonnucleoside reverse transcriptase inhibitor (NNRTI) or a ritonavir-boosted protease inhibitor (PI/r). Differences between these regimen types in the extent of the emergence of drug resistance on virological failure and the implications for further treatme...
BACKGROUND It is unknown whether HIV-positive patients experiencing virologic failure (VF) on boosted-PI (PI/r) regimens without drug resistant mutations (DRM) by standard genotyping harbor low-level PI resistant variants. CASTLE compared the efficacy of atazanavir/ritonavir (ATV/r) with lopinavir/ritonavir (LPV/r), each in combination with TVD in ARV-naïve subjects. OBJECTIVE To determine if...
We present measurements of the branching fraction and CP-violating asymmetries in the decay B0-->f0(980)K0S. The results are obtained from a data sample of 123 x 10(6) Upsilon(4S)-->BB decays. From a time-dependent maximum likelihood fit, we measure the branching fraction B(B0-->f0(980)(-->pi+pi-)K0)=(6.0+/-0.9+/-0.6+/-1.2)x10(-6), the mixing-induced CP violation parameter S=-1.62(+0.56)(-0.51)...
Kalmar [2, 1928-9] proved that Chess is strictly determined. Von Neumann-Morgenstern [5, 1944] proved the same for any finite two-person zero-sum perfect-information (PI) game. The latter result yields a minimax theorem for (finite) non-zero-sum PI games. Fix a PI, and a player, Ann. Convert this game to a two-person zero-sum game between Ann and the other players (considered as one player), in...
