Biofilm Inhibition and Antiviral Response of Cold Sprayed and Shot Peened Copper Surfaces: Effect of Surface Morphology and Microstructure.

Antibacterial properties of copper against planktonic bacteria population are affected by surface microstructure and topography. However, copper interactions with bacteria in a biofilm state are less studied. This work aims at better understanding the difference in biofilm inhibition of bulk, cold-sprayed, and shot-peened copper surfaces and gaining further insights on the underlying mechanisms using optical and scanning electron microscopy to investigate the topography and microstructure of the surfaces.

The efficiency of dynamic and static facial expression recognition.

Unlike frozen snapshots of facial expressions that we often see in photographs, natural facial expressions are dynamic events that unfold in a particular fashion over time. But how important are the temporal properties of expressions for our ability to reliably extract information about a person's emotional state? We addressed this question experimentally by gauging human performance in recognizing facial expressions with varying temporal properties relative to that of a statistically optimal ("ideal") observer. We found that people recognized emotions just as efficiently when viewing them as naturally evolving dynamic events, temporally reversed events, temporally randomized events, or single images frozen in time.

A pilot open label prospective study of memantine monotherapy in adults with ADHD.

Objectives: Available pharmacotherapies treat some adults with ADHD inadequately. A small literature suggests that glutamate modulation could have effects on ADHD.

Methods: Memantine, an N-methyl-d-aspartate (NMDA) receptor antagonist, was titrated to a maximum dose of 10 mg BID in 34 adult subjects aged 18-55 who met DSM-IV criteria for ADHD or ADHD NOS on structured interview.

Representativeness of participants in a clinical trial for attention-deficit/hyperactivity disorder? Comparison with adults from a large observational study.

Background: Clinical trials have demonstrated that pharmacotherapies can safely treat attention-deficit/hyperactivity disorder (ADHD) in adulthood. Eligibility criteria in these trials may significantly limit their external validity by excluding a significant portion of adults with ADHD in the general population. In particular, exclusion criteria may frequently exclude individuals with comorbid mental health conditions, which are common in the adult ADHD population.

Atomoxetine in the treatment of adults with subthreshold and/or late onset attention-deficit hyperactivity disorder-not otherwise specified (ADHD-NOS): a prospective open-label 6-week study.

The objective of this study was to evaluate the efficacy and tolerability of atomoxetine hydrochloride (ATX) in the treatment of adults with atypical manifestations of attention-deficit hyperactivity disorder (ADHD) (not otherwise specified [NOS]). We hypothesized that treatment with ATX will be safe and efficacious for the treatment of adults with ADHD-NOS. This was a 6-week, open-label, prospective treatment study of ATX monotherapy in 45 adult patients with ADHD-NOS assessed using standardized instruments for diagnosis and a robust oral daily dose of up to 1.
