Twenty-six in-patients with Diagnostic and Statistical Manual version IV (DSM-IV) criteria for opioid dependence were selected at random to receive either a combination of an 11-day low-dose buprenorphine and a 14-day carbamazepine regimen (n = 14) or a combination of an 11-day methadone and a 14-day carbamazepine regimen (n = 12) in a double-blind, randomized 14-day in-patient detoxification t...

OBJECTIVE To assess the efficacy, safety and tolerability of sodium valproate (800mg/die) compared with placebo in medication-overuse headache patients with a history of migraine without aura. METHODS This is a multicenter, randomized, double-blind, placebo-controlled study enrolled medication-overuse headache patients for a 3-month treatment period with sodium valproate (800mg/day) or placeb...

BACKGROUND Residential rehabilitation based on 'therapeutic community' treatment for drug users is a treatment option which is attractive to GPs and others referring drug users for treatment. Whilst there is evidence that maintenance-based programmes for drug users are effective, there have been fewer attempts to evaluate the effectiveness of abstinence-based programmes which are relatively mor...

INTRODUCTION Recent studies (Gold et al, 1978; Washton et al, 1980a) showing that the non-opiate antihypertensive agent, clonidine hydrochloride, suppresses signs and symptoms of opiate withdrawal, have suggested that clonidine and similar drugs might be useful in the clinical management of opiate detoxification. The fact that clonidine is not an opiate drug and does not itself produce addictio...

AIMS Evaluation of the efficacy and safety of slow-release oral morphine (SROM) compared with methadone for detoxification from methadone and SROM maintenance treatment. DESIGN Randomized, double-blind, double-dummy, comparative multi-centre study with parallel groups. SETTING Three psychiatric hospitals in Austria specializing in in-patient detoxification. PARTICIPANTS Male and female op...

Rationally designed nanoparticles that can bind toxins show great promise for detoxification. However, the conventional intravenous administration of nanoparticles for detoxification often leads to nanoparticle accumulation in the liver, posing a risk of secondary poisoning especially in liver-failure patients. Here we present a liver-inspired three-dimensional (3D) detoxification device. This ...

The goal of this study was to determine whether a new internal bioartificial liver utilizing porcine hepatocytes can perform detoxification and other metabolic functions. Such a system might aid in treating patients with moderate to severe liver failure and prolong patient survival until a matching organ is found for transplantation. Porcine hepatocytes were attached to a microcarrier and an in...

Few studies have examined the impact of mosquito adulticides on honey bees under conditions that reflect actual field exposure. Whereas several studies have evaluated the toxicity of mosquito control products on honey bees, most have been laboratory based and have focused solely on acute mortality as a measure of impact. The goal of this study was to determine effects of routine applications of...

Here it is shown that chaotic oscillations can appear after a series of period doublings in radiating diffusion flames when the activation temperature is high enough. It is also shown that period doubling cascades appear typically in very small regions and that they may not be observable if one starts with small perturbations of a steady flame.
