Olfactory Reference Syndrome: A Case Report and Screening Tool.

Olfactory reference syndrome (ORS) is a lesser known disorder that is related to obsessive-compulsive disorder. ORS is the obsessional and inaccurate belief that one is emitting a foul odor leading to embarrassment or concern about offending others, excessive hygiene behaviors, and social avoidance that significantly interferes with daily functioning. Although ORS is rare, it is challenging to diagnose.

Shooting with sound: optimizing an affordable ballistic gelatin recipe in a graded ultrasound phantom education program.

Objectives: The goal of this study was to investigate the durability and longevity of gelatin formulas for the production of staged ultrasound phantoms for education.

Methods: Gelatin phantoms were prepared from Knox gelatin (Kraft Foods, Northfield, IL) and a standard 10%-by-mass ordinance gelatin solution. Phantoms were durability tested by compressing to a 2-cm depth until cracking was visible.

Recovery from methamphetamine induced long-term nigrostriatal dopaminergic deficits without substantia nigra cell loss.

After administration of methamphetamine (METH) (2x2 mg/kg, 6 h apart) to vervet monkeys, long term but reversible dopaminergic deficits were observed in both in vivo and post-mortem studies. Longitudinal studies using positron emission tomography (PET) with the dopamine transporter (DAT)-binding ligand, [11C]WIN 35,428 (WIN), were used to show decreases in striatal WIN binding of 80% at 1 week and only 10% at 1.5 years.
