Metformin, Oxidative Stress, and Infertility: A Way Forward [PDF]
Infertility is a significant public health problem and its diagnosis and treatment are stressful, invasive and costly. Impaired fecundity is a growing health concern worldwide. Fertility predominantly depends on the maintenance of the quantity and quality of the ovarian reserve, which is determined by the extrinsic and intrinsic factors.

The Effect of Stress on Working Memory in Persons with Parkinson’s Disease [PDF]
Background: In addition to motor symptoms, persons with Parkinson’s disease (PD) experience several non-motor symptoms with challenges in working memory being particularly common. These cognitive challenges may worsen under stress.

Asymmetric effect of mechanical stress on the forward and reverse reaction catalyzed by an enzyme. [PDF]
The concept of modulating enzymatic activity by exerting a mechanical stress on the enzyme has been established in previous work. Mechanical perturbation is also a tool for probing conformational motion accompanying the enzymatic cycle.

Patellar tendon stress between two variations of the forward step lunge
Background: Patellar tendinopathy (PT) or “jumper's knee” is generally found in active populations that perform jumping activities. Graded exposure of patellar tendon stress through functional exercise has been demonstrated to be effective for the ...

An Efficient Clamp to Reduce Switch Voltage Stress of Forward Converter
In this study, an efficient clamp is proposed to reduce the switch voltage stress of a forward converter. The proposed clamp consists of a conventional LC snubber, a tertiary winding, and a diode. When the switch is turned OFF, the magnetizing inductor energy of the transformer is recovered directly into the flyback output, which is the tertiary ...

Forward Looking Banking Stress in EMU Countries [PDF]
Based on contingent claims analysis, CCA, this paper tries to estimate the systemic risk build-up in the European Economic and Monetary Union, EMU countries using a market based measure distance-to-default, DtD. It analyzes the individual and aggregated series for a comprehensive set of banks in each eurozone country over the period 2004-Q4 to 2013-Q2.

The Forward Testing Effect Is Resistant to Acute Psychosocial Retrieval Stress
Abstract: The forward testing effect refers to the finding that testing of previously studied information improves memory for subsequently studied newer information. Recent research showed that the effect is immune to acute psychosocial encoding/retrieval stress, i.e., stress that is induced before initial encoding.
