High-frequency deep brain stimulation (DBS) represents a major stake for treatment for treatment-resistant depression (TRD). We describe a preliminary trial of DBS of two potential brain targets in chronic TRD: the nucleus accumbens (Acb) and, in the event of failure, the caudate nucleus. Patients were followed for 6 months before surgery (M0). From M1 to M5, they underwent stimulation of the A...

OBJECTIVES (1) To describe the anticholinergic burden experienced by nursing home residents with dementia using the Anticholinergic Cognitive Burden (ACB) Scale; and (2) to determine the association of anticholinergic burden and engagement in activity. DESIGN Cross-sectional, using baseline data from an ongoing clinical trial. SETTING Nine nursing homes in Pennsylvania. PARTICIPANTS Eight...

Development of resistance in target pests is a major threat to long-term use of transgenic crops expressing Bacillus thuringiensis (Bt) Cry toxins. To manage and/or delay the evolution of resistance in target insects through the implementation of effective strategies, it is essential to understand the basis of resistance. One of the most important mechanisms of insect resistance to Bt crops is ...

BACKGROUND AND OBJECTIVES Adductor canal block (ACB) has been suggested as an analgesic alternative to femoral nerve block (FNB) for procedures on the knee, but its effect on quadriceps motor function is unclear. We performed a randomized, blinded study to compare quadriceps strength following adductor canal versus FNB in volunteers. Our hypothesis was that quadriceps strength would be preserve...

BACKGROUNDS & OBJECTIVE Antimicrobial resistance is a major health problem worldwide in hospitals. The main contributing factors are exposures to broad-spectrum antimicrobials and cross-infections. Understanding the extent and type of antimicrobial use in tertiary care hospitals will aid in developing national antimicrobial stewardship priorities. METHODS In this study, we have analyzed the a...

BACKGROUND African, Caribbean and other Black (ACB) people are a priority group for HIV prevention in Canada, but little is known about the epidemiology of HIV risk in this population. This paper helps fill the knowledge gap by: presenting service providers' and ACB people's perceptions about HIV risk in ACB populations; describing the distribution of HIV risk behaviours among ACB people accord...

Oral cancer is in approximately 30% of all cancers in India. This study was conducted to evaluate the cytotoxic activity of ethanolic extract of Acacia catechu bark (ACB) against human squamous cell carcinoma cell line-25 (SCC-25). Cytotoxic effect of ACB extract was determined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium Bromide assay. A. catechu extract was treated SCC-25 cells wit...

We reported previously that subsets of nucleus accumbens (Acb) neurons differentially encode information about goal-directed behaviors for "natural" (food and water) versus cocaine reward in animals well trained to self-administer the drug (Carelli et al., 2000). Here, we examined whether repeated exposure to cocaine is the crucial determinate of the selective encoding of cocaine versus water r...

BACKGROUND Review of recent journal articles and various relevant current textbooks provides strong evidence to show that anticholinergic burden is a material issue in frail and at-risk patients. This study assesses the anticholinergic burden in a group of patients in residential care facilities and then applies a theoretical intervention model. It is based on a scoring system known as the Anti...
