BACKGROUND Treatment of onchocerciasis using mass ivermectin administration has reduced morbidity and transmission throughout Africa and Central/South America. Mass drug administration is likely to exert selection pressure on parasites, and phenotypic and genetic changes in several Onchocerca volvulus populations from Cameroon and Ghana-exposed to more than a decade of regular ivermectin treatm...

Some examples are ...

BACKGROUND Drug overdose is a public health crisis in the United States, due in part to the unintended consequences of increases in prescribing of opioid analgesics. Many clinicians evaluate risk markers for opioid-related harms when prescribing opioids for chronic pain; however, more data on predictive risk markers are needed. Risk markers are attributes (modifiable and non-modifiable) that ar...

Waveform relaxation is a numerical method for solving large-scale systems of ordinary differential equations on parallel computers. It differs from standard iterative methods in that it computes the solution on many time levels or along a continuous time interval simultaneously. This paper deals with the acceleration of the standard waveform relaxation method by successive overrelaxation (SOR) ...

Recombination of a surface-radical with a surface-olefin (SR-SOR) to form a six-membered ring is a critical step in the current mechanism for chemical vapor deposition growth of the diamond (100) surface. We estimate the rate constant for SR-SOR by combining quantum chemistry calculations, molecular mechanics calculations, and transition state theory. The ab initio calculations include extensiv...

OBJECTIVE We explored the relationships between sensory modulation and health-related quality of life (HRQOL), social supports, and mental health symptoms of anxiety and depression. METHOD Twenty-eight adult volunteers ages 18-60 participated in the study. Fourteen adults were sensory overresponsive (SOR), and 14 adults in a matched comparative group were not sensory overresponsive (NSOR). Al...
