The threat to public health posed by drug-resistant bacteria is rapidly increasing, as some of healthcare's most potent antibiotics are becoming obsolete. Approximately two-thirds of the world's antibiotics are derived from natural products produced by Streptomyces encoded biosynthetic gene clusters. Thus, to identify novel gene clusters, we sequenced the genomes of four bioactive Streptomyces strains isolated from the soil in San Diego County and used Bacterial Cytological Profiling adapted for agar plate culturing in order to examine the mechanisms of bacterial inhibition exhibited by these strains.

Participants (N = 50) were drawn from two public high schools in a culturally diverse metropolitan area. A detailed procedure for identifying and confirming late-onset ADHD cases is described.

Method: Semi-structured, in-depth interviews were conducted with 14 older Spanish-speaking Hispanic immigrants with major depression who participated in a collaborative care program within a public sector specialty geriatric clinic in Los Angeles, CA.
Results: Findings revealed that participants used various idioms to describe their experiences with depression, and that depression had a strong impact on functioning.
Background: Several risk factors are associated with multiple sclerosis (MS) progression and may be amenable to intervention.
Objective: To systematically review the evidence for interventions targeting risk factors for MS progression.
Methods: We searched six databases and existing reviews till March 2015 and consulted with experts to identify randomized controlled trials (RCTs) of interventions targeting MS risk factors (PROSPERO 2015:CRD42015016461).
Background: The presenting symptoms and rate of progression of multiple sclerosis (MS) are very heterogeneous. The diverse clinical manifestations and the clinical course of the disease may vary with modifiable risk factors.
Objective: To systematically review modifiable risk factors and exposures associated with MS progression.

Patients with Bipolar disorder smoke more than the general population. Smoking negatively impacts mortality and clinical course in Bipolar disorder patients. Prior studies have shown contradictory results regarding the impact of psychosis on smoking behavior in Bipolar disorder.

The variability and the phylogenetic relationships between the eleven strains were analyzed using 172 ISSR-PCR markers. A high level of polymorphism (near 80%) was found using these molecular markers.
