Effects of montmorency tart cherry (L. Prunus Cerasus) consumption on nitric oxide biomarkers and exercise performance
(Wiley, 2018)The purpose of this study was to investigate the effects of Montmorency tart cherry juice (MC) on nitric oxide (NO) biomarkers, vascular function, and exercise performance. In a randomized, double-blind, placebo ... -
Effects of Montmorency tart cherry (Prunus Cerasus L.) consumption on vascular function in men with early hypertension
(Amer Soc Nutrition, 2016)Background: Tart cherries contain numerous polyphenolic compounds that could potentially improve endothelial function and reduce cardiovascular disease risk. Objective: We sought to examine the acute effects of ... -
Effects of organic loading rates on microbial communities and biogas production from water hyacinth: a case of mono‐ and co‐digestion
(Wiley, 2019)Background Anaerobic digestion is a microbial driven process, which results in biogas production. Although important, the relative abundance of microbial communities can be affected by disturbances such as feeding rates. ... -
Effects of PCB exposure on serum thyroid hormone levels in dogs and cats
(Elsevier, 2019)Polychlorinated biphenyls (PCBs) and their hydroxylated metabolites (OH-PCBs) might disrupt thyroid function. However, there is no clear evidence of PCB exposure disrupting thyroid hormone (TH) homeostasis in dogs and cats. ... -

The effects of residual platelets in plasma on plasminogen activator inhibitor-1 and plasminogen activator inhibitor-1-related assays
(PLOS, 2017)Due to controversial evidence in the literature pertaining to the activity of plasminogen activator inhibitor-1 in platelets, we examined the effects of residual platelets present in plasma (a potential pre-analytical ... -
Effects of seated and standing cold water immersion on recovery from repeated sprinting
(Taylor & Francis, 2015)This study investigated the effects of two different hydrostatic pressures (seated or standing) during cold water immersion at attenuating the deleterious effects of strenuous exercise on indices of damage and recovery. ... -
The effects of stirring, population levels and a potential anti-nematodal product on the respiration of second-stage juveniles of Meloidogyne incognita measured with different technology
(Brill, 2016)The oxygen consumption rate (OCR) of Meloidogyne incognita second-stage juveniles (J2) was measured using polarographic oxygen sensor (POS) and fibre-optic oxygen sensor (FOS) technology. The effect of stirring speed on ... -

(SAAPAM, 2014)The relationship between strategic management and labour unions has proven to be significant towards organisational productivity. This relationship has the power of influencing the employees positively or negatively depending ... -
Effects of strength training on postpubertal adolescent distance runners
(Wolters Kluwer, 2018)Purpose Strength training activities have consistently been shown to improve running economy (RE) and neuromuscular characteristics, such as force-producing ability and maximal speed, in adult distance runners. However, ... -
Effects of strength training on the physiological determinants of middle- and long-distance running performance: a systematic review
(Springer, 2018)Background Middle- and long-distance running performance is constrained by several important aerobic and anaerobic parameters. The efficacy of strength training (ST) for distance runners has received considerable attention ... -
