A case of phenibut withdrawal and treatment with baclofen

Phenibut(β-phenyl-γ-aminobutyric acid)is a psychoactive gamma-aminobutyric acid(GABA)analog marketed online as a nutritional and nootropic(cognition enhancing)supplement.Phenibut consumption poses a high risk of potential abuse.Withdrawal from phenibut mimics benzodiazepine and alcohol withdrawal and can be dangerous.A number of approaches have been described for phenibut withdrawal,including protocols that include baclofen,but for inpatient and outpatient use.Here we describe a 30-year-old male who presented to an emergency department(ED)with insomnia,anxiety and palpitations after he stopped taking phenibut.

通过液相混合制备具有优异耐疲劳性和耐磨性的胶料

在聚合物中通过获得高质量的填充剂分散可以大大提高硫化胶的耐磨性能和耐疲劳性能。并用丁二烯橡胶的Transfinity胶料可提高硫化胶的磨耗性能,但拉伸强度和撕裂强度会受到影响;在实际应用中拉伸强度和撕裂强度也许很重要,而耐冲击磨耗性能是关键。本研究还提出了能清楚说明提高炭黑在聚合物中的分散性对硫化胶耐磨性影响的磨耗试验方法。
