background : aids is acquired by infection with hiv (human immuno-deficiency virus). it leaves the host susceptible to malignant and unusual infections especially opportunistic ones. most of aids patients infected with opportunistic parasitic infections die because of chronic diarrhea and deaths due to cryptosporidium diarrhea in aids patients are considerable in the recent two decades. the aim...

In this position paper, we outline a vision for a new type of engineering: immuno-engineering, that can be used for the development of biologically grounded and theoretically understood Artificial Immune Systems (AIS). We argue that, like many bio-inspired paradigms, AIS have drifted somewhat away from the source of inspiration. We also argue that through an interdisciplinary approach, it is po...

OBJECTIVE This study estimated prevalences and correlates of stimulant diversion in the United States and examined relationships between diversion and measures of abuse or dependence. METHODS We conducted descriptive and multivariate analysis of data from the National Survey on Drug Use and Health. Key measures were nonmedical use (misuse) of any prescription stimulant, any stimulant other th...

BACKGROUND Previous studies document neuropsychological deficits associated with stimulant abuse, but findings are inconsistent. METHODS We identified 50 twin pairs in which only 1 member had heavy stimulant abuse (cocaine and/or amphetamines) ending at least 1 year before the evaluation. The co-twin control research design controls for familial vulnerability and makes it easier to identify n...

Disc immuno-immobilization is a simple method for typing the flagellar phase of Salmonella enterica. We re-examined this method using commercial antisera, which contains the preservative sodium azide. Originally prepared motility agar activates bacterial motility and renders S. enterica resistant to sodium azide, resulting in the formation of immuno-immobilization lines around reactive immuno-d...

Use of illicit stimulants such as methamphetamine, cocaine, and ecstasy is an increasing health problem. Chronic use can cause neurotoxicity in animals and humans but the long-term consequences are not well understood. The aim of the current study was to investigate the long-term effect of stimulant use on the morphology of the human substantia nigra. We hypothesised that history of illicit sti...
