AbstractEccentric exercise typically induces muscle damage that can cause detrimental effects on an athlete’s performance. Therefore, it is vital to find a recovery strategy that will increase the rate of recovery, alleviate the signs and symptoms associated with exercise-induced muscle damage, and return the athlete to peak performance levels as quickly as possible. Water immersion, in the form of cold water immersion, hot water immersion and contrast water therapy are becoming increasingly popular interventions used to alleviate the signs and symptoms of exercise-induced muscle damage and improve recovery after eccentric exercise. The purpose of the study was to determine the effects of contrast water therapy and hot water immersion on the signs and symptoms of exercise-induced muscle damage using indirect markers of muscle damage. These markers of muscle damage include; perceived muscle soreness, pressure pain threshold, squat jump, range of motion, flexibility, creatine kinase and limb circumference and are used in this study as a measure of the signs and symptoms of exercise-induced muscle damage. The purpose of Chapter 4 (Study 1) was to determine the reproducibility of these indirect markers of muscle damage. Overall, no systematic bias was found for any of the variables apart from creatine kinase. However, several performance and functional measurement tools; creatine kinase, flexibility, perceived soreness and pressure pain threshold exhibited low reproducibility, whilst creatine kinase, range of motion, perceived muscle soreness, limb circumference, and pressure pain threshold demonstrated good to excellent reliability however, squat jump demonstrated good xv reliability. With several of the indirect markers of muscle damage demonstrating poor to low reliability, discretion is advised when using these measures to detect systematic change, as the low reproducibility may obscure the true experimental results. The purpose of Chapter 5 (Study 2) was to determine the effects of contrast water therapy, and hot water immersion on the signs and symptoms of exercise-induced muscle damage. There is a plethora of studies aimed at determining the effects of cold water immersion and contrast water therapy on the signs and symptoms of exercise-induced muscle damage (Bailey et al., 2007, Eston and Peter., 1999a, Halson et al., 2008., Ingram et al., 2009, Montgomery et al., 2008, Vaile et al., 2008b). However, limited studies have determined the effects of hot water immersion alone (Kuligowski et al., 1998). All participants in this study completed a muscle damaging protocol which consisted of a 40 minute downhill run. Subsequently, participants were either treated with hot water immersion, contrast water therapy, or no water immersion for 40 minutes at 0 hours, 24 hours, and 48 hours post downhill run. Perceived muscle soreness, pressure pain threshold, squat jump, range of motion, flexibility, limb circumference and creatine kinase were measured on five separate occasions (pre-downhill run, immediately post downhill run, 24, 48 and 72 hours post downhill run). Results demonstrated that contrast water therapy had an improved effect on alleviating several signs and symptoms of exercise-induced muscle damage. Briefly, peak decrements at 24 hours in creatine kinase, pressure pain threshold, flexibility, squat jump, and perceived muscle soreness were found in the hot water immersion group and contrast water immersion groups, where as peak decrements at 48 hours for pressure pain threshold, flexibility, and squat jump were found in the control group.

AFM-detected apoptosis of hepatocellular carcinoma cells induced by American ginseng root water extractQu, Yingmin; Wang, Zuobin; Zhao, Feihu; Liu, Jinyun; Zhang, Wenxiao; Li, Jingmei; Song, Zhengxun; Xu, Hongmei; Changchun University of Science and Technology; Eindhoven University of Technology; et al. (Elsevier, 2017-10-12)American ginseng as a common and traditional herbal medicine has been used in cancer treatment for many years. However, the effect of American ginseng on the cancer cell response (i.e. apoptosis) has not been fully understood yet. Previous studies demonstrated that cellular apoptosis was associated with the changes of mechanical and morphological properties. Therefore, in this study, mechanical and morphological characterizations were carried out by both atomic force microscope (AFM) and inverted optical microscope to investigate the apoptosis of hepatocellular carcinoma (SMMC-7721) cells affected by American ginseng root water extract (AGRWE). The results showed that the cells treated with AGRWE exhibited significantly larger surface roughness, height and elastic modulus values than control group. Moreover, those parameters were upregulated under the higher concentration of AGRWE and longer culture time. Consequently, it indicates that the mechanical and morphological properties can be used as the apoptotic characteristics of SMMC-7721 cells. Also, the increased surface roughness and elastic modulus of cells under the AGRWE treatment have shown that the apoptosis of SMMC-7721 cells can be enhanced by AGRWE. This will provide an important implication for hepatocelluar carcinoma treatment and drug development.
The occurrence and potential health risk of microcystins in drinking water of rural areas in China.Zheng, Weiwei; Yang, Lan; Ma, Wuren; Huang, Yu; Crabbe, M. James C.; Qu, Weidong (Elsevier, 2018-12-26)Large-scale use of nitrogen and phosphorus fertilizers in agricultural production, environmental pollution and climate warming cause frequent algal blooms and the generation of algal toxins in water bodies in China. Algal pollution is increasing and microcystins (MCs) are detectable in both surface and ground water in China at sub- μg/L and μg/L levels. Toxicological studies show that microcystins have hepatic and renal toxicity, genotoxicity, tumor-promoting effects, neurotoxicity, reproductive and developmental toxicity. Epidemiological evidence from China further reveals that chronic exposure to MCs through drinking water and liver cancer are positively correlated and demonstrate that MCs in drinking water are a main risk factor in liver cancer. Effectively controlled water pollution, reduced sewage discharge, and enhanced wastewater treatments are pivotal measures to control algal pollution and toxins in the drinking water of rural China.
Water quality investigations of the River Lea (NE London)Patroncini, Deborah (University of BedfordshireUniversity of Bedfordshire, 2013-01)The Lea Navigation in the north-east of London, a canalised reach of the River Lea, is affected by episodes of very low levels of dissolved oxygen. The problem was detected by the Environment Agency in the stretch from the confluence with Pymmes Brook (which receives the final effluent of Deephams sewage treatment works) to the Olympic area (Marshgate Lane, Stratford). In this project, possible causes and sources of the poor water quality in the Lea Navigation have been investigated using a multi-parameter approach. A study of physico-chemical parameters, obtained from Environment Agency automated monitoring stations, gave a clear picture of the poor river water quality at three sites in this reach. River water ecotoxicity to the freshwater alga Pseudokirchneriella subcapitata was determined by algal growth inhibition tests, following the OECD guidelines. Moreover, a novel protocol was developed which involved the use of E. coli biosensors (CellSense) operating at a lower potential than the standard protocol and using pre-concentrated river water samples. This protocol is promising and it has the potential to be a useful tool to determine the toxicity of contaminants at environmental concentrations. Furthermore, the developed protocol is a rapid, easy to perform bioassay, with potential application in achieving the aims of the Water Framework Directive (WFD). In addition to the data from the Environment Agency automatic monitoring stations and the laboratory-based tests, two in situ monitoring approaches were performed: 1) a detailed spatial seasonal monitoring of physico-chemical parameters of river water at twenty-three sites, and 2) algal growth inhibition tests, with algae entrapped in alginate beads, at seven monitoring stations. Results showed chronic pollution, and identified polar compounds in the river water and high bacterial concentrations as possible causes of low dissolved oxygen levels. This study confirmed the negative impact of Deephams STW (throughout Pymmes Brook) on the water quality of the Lea Navigation. However, there was evidence of other sources of pollution, in particular Stonebridge Brook was identified as uncontrolled source of pollution and untreated wastewater. Other possible sources include Old Moselle Brook, diffuse pollution from surface runoff, boat discharges and other undetected misconnections. Finally, in the light of the WFD, this project provides a case study on the investigation of river water quality, providing evidence that the multiparameter approach is reliable, and low cost approach for the monitoring of freshwater bodies.
