THE EFFECT OF PERIODIZED RESISTANCE TRAINING ON SPRINTING SPEED, AGILITY AND POWER OF DOMESTIC FEMALE CRICKET PLAYERS

Introduction: It has been well documented that there is great difference between male and female according to body shape and other characteristics like ability to perform work, muscular power and strength. There is almost no study conducted on female cricket participants under the age of twenty. This study was designed to determine effects of periodized resistance training on sprinting speed, agility, power in domestic young female cricketers. Material & Methods: This was a parallel group randomized control trail that utilized purposive sampling to recruit 46 participants. Data was collected from Abdul-Qadeer cricket academy, Kinnaird College for women.46 young female cricketers completed the study, of which 23 were in experimental group and 23 were in control group. In experimental group, 8 week of resistance training program had been introduced in addition to their regular training sessions, while control group only followed their regular training sessions. To evaluate the speed, agility and power tests such as (run a three test, Illinois agility test, sergeant jump test and seated medicine ball throw) were performed before and after the experimental or control training. Results: Periodized resistance training significantly increase (p = 0.01) sprinting speed measured by run a three test. Post intervention mean±SD of Illinois agility test was 19.817±1.579 that shows significant effect of periodized resistance training on agility (p=0.001). Post intervention mean±SD of sergeant jump test was 7.782±2.448 which shows significant effect of periodized resistance training on power of lower limb (p=0.001). Post intervention mean±SD of seated medicine ball throw was 28.194±3.878 that shows that there is no significant effect of periodized resistance training on power of upper limb (p=0.89). Conclusion: This study concluded that sprinting speed, agility and power of lower limb is improved by periodized resistance training

An alternative bioassay using Anabas testudineus (Climbing perch) cholinesterase for metal ions detection

Climbing Perch or its scientific name, Anabas testudineus is one of the freshwater fish belonging to the family of Anabantidae. It is widely distributed in ponds, swamps and estuaries in Asia. In this study, cholinesterase (ChE) was partially purified from the liver of A. testudineus through ion exchange chromatography. This purification method provided a recovery yield of 5.36% with a purification fold of 6.6. The optimum conditions for ChE assay were identified to be 2.5 mM of butyrylthiocholine iodide (BTC) with pH 8.0 in Tris-HCl buffer at 40°C. Substrate specificity profile also indicated that ChE favours BTC as substrate because it records the highest catalytic efficiency (V/K). Protein analysis through Native-PAGE showed that ion exchange chromatography is an effective method to partially purify ChE. Metal ion inhibition tests were conducted and mercury (Hg) was found to show the highest inhibition effect (87.30%) whereas lead (Pb) shows the lowest inhibition effect (28.01%). All these findings showed that partially purified ChE from the liver of A. testudineus is suitable to be used as a bioindicator to detect the presence of metal ions

EFFECTS OF HOLMICH PROTOCOL AND MYOFASCIAL RELEASE TECHNIQUE ON GROIN PAIN IN TENNIS PLAYERS

Introduction: Tennis with a normal 17.9 million players is one of the most renowned games with a colossal addition in young tennis players as of late. The prevalence of groin injury increases rapidly in tennis players due to demand of rapid change in direction. Material & Methods: Once ethical approval was taken from Institutional review Board (REC/Letter-00722), a Randomized Clinical Trial (RCT) was conducted on 22 players through nonprobability purposive sampling in Pakistan Tennis Federation, Islamabad. Players were randomly divided into two groups by sealed and envelop method. Group A received Holmich protocol while group B received myofascial release technique. Other than demographics, functional tests like hip range of motion, visual analogue scale, t-test, Edgren sidestep test and triple hop test were conducted to assess the techniques given to groups. Data was analysed using SPSS 21. Trial is registered in US clinical trial registry (NCT04642300). Results: The results of the study show that there was no significant difference between Myofascial release technique and holmich protocol in athletes with groin pain (P value˃0.05). Mean age of the tennis players was 23.14±4.5 in years. Pre and post comparison of both interventions shows significant effect in Range of motion, Pain, Agility and hop test. (P value˂0.01). Conclusion: From the results it can be seen that there was no significance between the two techniques. So in conclusion both techniques can be used to treat groin pain and get successful results

Kinetic analysis of the adsorption of glyphosate onto palm oil fronds activated carbon

Existing techniques for the treatment of pollutants include membrane separation, ion exchange, precipitation, transformation and biosorption. Of all of this technology, biosorption has several positive aspects which include low operating expenses, very efficient detoxification of toxicants at low concentrations, low amount of disposal materials and does not need nutrient requirements as in bacterial-based remediation, the latter of which is limited by the presence of heavy metals and other toxicants. The biosorption of glyphosate on palm oil fronds activated carbon can be an efficient and low-cost tool for remediation of glyphosate. The absorption kinetics data of biosorption isotherm on the biosorption of glyphosate on palm oil fronds activated carbon were analyzed using three models—pseudo-1st, pseudo-2nd and Elovich, and fitted using non-linear regression. The Elovich model was the poorest in fitting the curve based on visual observation followed by the pseudo-1st order. Statistical analysis based on root-mean-square error (RMSE), adjusted coefficient of determination (adjR2), bias factor (BF), accuracy factor (AF), corrected AICc (Akaike Information Criterion), Bayesian Information Criterion (BIC) and Hannan–Quinn information criterion (HQC) that showed that the pseudo-second order model is the best model. Kinetic analysis using the pseudo-second order model at 250 mg/L glyphosate gave a value of equilibrium sorption capacity qe of 94.12 mg g-1 (95% confidence interval from 89.913 to 98.332) and a value of the pseudo-second-order rate constant, k2 of 0.02 (95% confidence interval from 0.012 to 0.023). Further analysis is needed to provide proof for the chemisorption mechanism usually tied to this kinetic

Isothermal modelling of the adsoprtion of glyphosate onto palm oil fronds activated carbon

Glyphosate is a heavily usage herbicide in Malaysia. It inhibits amino acids synthesis in plants and microorganisms with the latter inhibition makes it difficult to find biodegradation microorganism as a bioremediation agent for this pesticide. One candidate for bioremediation is biosorption that has several positive aspects which include low operating expenses, very efficient detoxification of toxicants at low concentrations, low amount of disposal materials and does not need nutrient requirements as in bacterial-based remediation, the latter of which is limited by the presence of heavy metals and other toxicants. The biosorption of glyphosate on palm oil fronds activated carbon can be an efficient and low-cost tool for remediation of glyphosate. The absorption kinetics data of biosorption isotherm on the biosorption of glyphosate on oil palm fronds activated carbon were analyzed using modelled according to various models ranging from one to five parameters models such as Henry, Langmuir, Dubinin-Radushkevich, Freundlich, BET, Toth, Sips, Fritz-Schlunder IV, Baudu and Fritz-Schlunder V, and fitted using non-linear regression. Only the Henry, Langmuir, Freundlich, BET and Toth models can fit the data. Statistical analysis based on root-mean-square error (RMSE), adjusted coefficient of determination (adjR2), bias factor (BF), accuracy factor (AF), corrected AICc (Akaike Information Criterion) showed that the Langmuir model is the best model. The calculated Langmuir parameters bL value of 0.002 L/mg (95% confidence interval from 0.001 to 0.004) and qmL value of 255.5 mg/g (95% confidence interval from 160.90 to 350.11)

Kinetic analysis for the removal of copper using Durvillaea antarctica

Existing techniques for the treatment of pollutants include membrane separation, ion exchange, precipitation, and transformation and biosorption. Of all this technology, biosorption has several positive aspects which include low operating expenses, very efficient detoxification of toxicants at low concentrations, low amount of disposal materials and does not need nutrient requirements as in bacterial-based remediation, the latter of which is limited by the presence of heavy metals and other toxicants. The reduction of copper by Durvillaea antarctica, an alga that lives as south as the Antarctic region can be an efficient and low-cost tool for remediation of copper. In this study, the kinetics of copper biosorption is modelled according to the pseudo-first order, pseudo-second order and Elovich models. Statistical analysis based on root-mean-square error (RMSE), adjusted coefficient of determination (adjR2), bias factor (BF), accuracy factor (AF) and corrected AICc (Akaike Information Criterion) showed that the pseudo-second order model is the best model. Kinetic analysis using the pseudo-second order model at 0.15 mM copper gave a value of equilibrium sorption capacity qe of 0.150 mmol g-1 (95% confidence interval from 0.149 to 0.151) and a value of the pseudo-second-order rate constant, k2 of 8.605 (95% confidence interval from 7.016 to 10.194)

Effects of a high-dose 24-h infusion of tranexamic acid on death and thromboembolic events in patients with acute gastrointestinal bleeding (HALT-IT): an international randomised, double-blind, placebo-controlled trial

Background: Tranexamic acid reduces surgical bleeding and reduces death due to bleeding in patients with trauma. Meta-analyses of small trials show that tranexamic acid might decrease deaths from gastrointestinal bleeding. We aimed to assess the effects of tranexamic acid in patients with gastrointestinal bleeding. Methods: We did an international, multicentre, randomised, placebo-controlled trial in 164 hospitals in 15 countries. Patients were enrolled if the responsible clinician was uncertain whether to use tranexamic acid, were aged above the minimum age considered an adult in their country (either aged 16 years and older or aged 18 years and older), and had significant (defined as at risk of bleeding to death) upper or lower gastrointestinal bleeding. Patients were randomly assigned by selection of a numbered treatment pack from a box containing eight packs that were identical apart from the pack number. Patients received either a loading dose of 1 g tranexamic acid, which was added to 100 mL infusion bag of 0·9% sodium chloride and infused by slow intravenous injection over 10 min, followed by a maintenance dose of 3 g tranexamic acid added to 1 L of any isotonic intravenous solution and infused at 125 mg/h for 24 h, or placebo (sodium chloride 0·9%). Patients, caregivers, and those assessing outcomes were masked to allocation. The primary outcome was death due to bleeding within 5 days of randomisation; analysis excluded patients who received neither dose of the allocated treatment and those for whom outcome data on death were unavailable. This trial was registered with Current Controlled Trials, ISRCTN11225767, and ClinicalTrials.gov, NCT01658124. Findings: Between July 4, 2013, and June 21, 2019, we randomly allocated 12 009 patients to receive tranexamic acid (5994, 49·9%) or matching placebo (6015, 50·1%), of whom 11 952 (99·5%) received the first dose of the allocated treatment. Death due to bleeding within 5 days of randomisation occurred in 222 (4%) of 5956 patients in the tranexamic acid group and in 226 (4%) of 5981 patients in the placebo group (risk ratio [RR] 0·99, 95% CI 0·82–1·18). Arterial thromboembolic events (myocardial infarction or stroke) were similar in the tranexamic acid group and placebo group (42 [0·7%] of 5952 vs 46 [0·8%] of 5977; 0·92; 0·60 to 1·39). Venous thromboembolic events (deep vein thrombosis or pulmonary embolism) were higher in tranexamic acid group than in the placebo group (48 [0·8%] of 5952 vs 26 [0·4%] of 5977; RR 1·85; 95% CI 1·15 to 2·98). Interpretation: We found that tranexamic acid did not reduce death from gastrointestinal bleeding. On the basis of our results, tranexamic acid should not be used for the treatment of gastrointestinal bleeding outside the context of a randomised trial

Microbiological Reduction of Molybdenum to Molybdenum Blue as a Sustainable Remediation Tool for Molybdenum: A Comprehensive Review

Molybdenum (Mo) microbial bioreduction is a phenomenon that is beginning to be recognized globally as a tool for the remediation of molybdenum toxicity. Molybdenum toxicity continues to be demonstrated in many animal models of spermatogenesis and oogenesis, particularly those of ruminants. The phenomenon has been reported for more than 100 years without a clear understanding of the reduction mechanism, indicating a clear gap in the scientific knowledge. This knowledge is not just fundamentally important—it is specifically important in applications for bioremediation measures and the sustainable recovery of metal from industrial or mine effluent. To date, about 52 molybdenum-reducing bacteria have been isolated globally. An increasing number of reports have also been published regarding the assimilation of other xenobiotics. This phenomenon is likely to be observed in current and future events in which the remediation of xenobiotics requires microorganisms capable of degrading or transforming multi-xenobiotics. This review aimed to comprehensively catalogue all of the characterizations of molybdenum-reducing microorganisms to date and identify future opportunities and improvements

Evaluation of cholinesterase from the muscle and blood of Anabas testudineus as detection of metal ions

Another alternative source of cholinesterase (ChE) that is sensitive towards metal ion has been revealed. ChE from muscle and blood of Anabas testudineus were extracted and purified through ammonium sulphate precipitation followed by an ion exchange chromatography with a total recovery of 47.66% and 7.92%, respectively. Kinetic study measured that BTC was the most preferable synthetic substrate to blood ChE while muscle ChE preferred PTC with the biomolecular constant of 1.07 and 0.53 mM, respectively. Optimum pH for blood and muscle ChE were determined at 8 and 9. Both ChE shared an optimum temperature of 30°C. Inhibition study showed that muscle ChE has inhibited more than 50% of metal ions namely arsenic, chromium, copper, mercury and zinc compared to blood ChE with only copper and mercury. Studies on half inhibitory effect (IC50) of blood and muscle ChE were tested with series concentration of mercury calculated at 1.003 and 1.048 mg/L. This result will be used as a reference for future development of biosensor
