In drug abusers, white matter hyperintensities, perfusion deficits, and metabolic disturbances are detected by neuroimaging analyses in different brain regions. A specific pattern of involvement or a predominance of a specific brain region cannot be drawn. To examine changes of the cerebral microvasculature as a possible morphological substrate of the neuroimaging findings, brain specimens of 1...

The present study was conducted to determine the effect of seasonal and climatic variations on semen characteristics of Nili-Ravi buffalo breeding bulls in Sahiwal and Bahawalpur districts of Punjab, Pakistan. For this purpose, 14 adult NiliRavi buffalo breeding bulls (n=7 from each of Semen Production Unit (SPU) Qadirabad, Sahiwal and SPU Karaniwala, Bahawalpur), were used. Semen samples were ...

This paper presents a new variable step-size normalized subband adaptive filter (VSS-NSAF) algorithm. In the proposed VSS-NSAF, the step-size changes in order to have largest decrease in the mean square deviation (MSD) for sequential iterations. To reduce the computational complexity of VSS-NSAF, the variable step-size selective partial update normalized subband adaptive filter (VSS-SPU-NSAF) i...

BACKGROUND There is increasing interest in naltrexone, an opiate antagonist, in the treatment of opiate addicts. The effects of naltrexone are often compromised by a lack of compliance and drop-out. The effects of this compound are probably more favorable when combined with a psychosocial intervention such as the Community Reinforcement Approach (CRA). AIM To explore the effects of a combinat...
