Among these, herbal weight-loss products (HWLPs) often attract users due to their health claims, assumed safety, easy availability, affordable price, extensive marketing, and the perceived lack of need for professional oversight. Reports suggest that certain HWLPs may lead to onset or exacerbation of psychiatric disturbances. Here we review the available evidence on psychiatric adverse effects of HWLPs due to their intrinsic toxicity and potential for interaction with psychiatric medicationsPeer reviewe
25C-NBOMe: Preliminary Data on Pharmacology, Psychoactive Effects, and Toxicity of a New Potent and Dangerous Hallucinogenic Drug
Introduction. The use of novel psychoactive substances (NPSs) has rapidly increased as well as their online availability. The aim of this paper is to provide a comprehensive review of the nature and the risks associated with 25C-NBOMe, which has recently appeared in the drug market. Methods. A systematic analysis of the scientific literature and a qualitative assessment of online and media resources (e.g., e-newsgroups, chat-rooms, and e-newsletters) in 10 languages were carried out. Results. 25C-NBOMe is sold online as legal LSD or as research chemical with different designations such as "Boom, " "Pandora, " "Holland film, " or "N-bomb. " It is a partial agonist of 5-HT2A receptors. It is usually ingested orally/sublingually and, less commonly, nasally, through injection, vaginally, rectally, and smoked. Its effects include sublingual numbing, stimulation, "body high, " hallucinations, dissociation, and anxiety. 25C-NBOMe presents high risk of overdoses; acute toxicity and fatalities have been reported. Conclusions. 25C-NBOMe consumption represents an emerging phenomenon with potential harmful effects. Its use is increased by its online availability at low costs. Health and other professionals should be informed about this new trend of substance use
GENERALIZED AND SPECIFIC EMOTION IMPAIRMENTS AS POTENTIAL MARKERS OF SEVERITY IN OBSESSIVECOMPULSIVE DISORDER: A PRELIMINARY STUDY USING FACIAL ACTION CODING SYSTEM (FACS)
Background: The role of emotional deficits in the poor outcomes of patients with Obsessive-Compulsive Disorder (OCD) has
been emphasized. Generalized and specific emotional abnormalities have been reported, often related to OCD severity and
functional disabilities. The objective of the present study was to assess the abilities of experiencing and displaying emotions in OCD
patients in response to specific stimuli in relation with the severity of their clinical condition.
Subjects and methods: Thirty-six individuals participated in the study: 10 OCD patients with severe symptoms, 11 with mildmoderate
symptoms, and 15 healthy controls. All participants watched emotion-eliciting video clips while their facial activity was
videotaped. The congruent/incongruent feeling of emotions and the facial expression in reaction to emotions were evaluated.
Results: The two subgroups of OCD patients presented similarly incongruent emotive feelings and facial expressions
(significantly worse than healthy participants). Moreover, OCD patients with severe symptoms expressed the emotion of happiness
and disgust significantly less appropriately than OCD patients with mild-moderate symptoms.
Conclusions: The present data support the hypothesis that impaired emotional processing may: (i) represent a potential
contributor to poor outcome in OCD; (ii) constitute a warning sign for clinicians to establish a more comprehensive protocol for
more severe cases; (iii) influence therapeutic strategies used to treat this disorder
Measurement of the Ratio of b Quark Production Cross Sections in Antiproton-Proton Collisions at 630 GeV and 1800 GeV
We report a measurement of the ratio of the bottom quark production cross
section in antiproton-proton collisions at 630 GeV to 1800 GeV using bottom
quarks with transverse momenta greater than 10.75 GeV identified through their
semileptonic decays and long lifetimes. The measured ratio
sigma(630)/sigma(1800) = 0.171 +/- .024 +/- .012 is in good agreement with
next-to-leading order (NLO) quantum chromodynamics (QCD)
Measurement of Z(0) and Drell-Yan production cross sections using dimuons in (p)over-bar-p collisions at root s=1.8TeV
We present a measurement of Z(0) boson and Drell-Yan production cross sections in (p) over bar p collisions at root s = 1.8 TeV using a sample of 107 pb(-1) accumulated by the Collider Detector at Fermilab. The Drell-Yan cross section is measured in the mass range of M-mu mu>40 GeV/c(2). We compare the measurements with the predictions of quantum chromodynamics in both leading order and next-to-leading order, incorporating the recent parton distribution functions. The measurements are consistent with the standard model expectations. [S0556-2821(99)01603-3]
