Gross motor skills (GMS) are the foundation for humans reaching an optimum level of motor competence necessary to undergo normal development, maintain health, and achieve athletic excellence. Yet, there is evidence that GMS levels of children are on a decline globally. Therefore, the main purpose of this study was to investigate the effectiveness of traditional cultural games (TCG) skills, practiced according to different amounts of contextual interference (CI), on the acquisition and retention of GMS. A total of 103 Pakistani primary school children aged between 7 and 10 years were recruited for this study. Participants were randomly assigned to four practice groups with different amounts of CI: Block (B) (low interference), gradually increasing (GI) (moderate interference), random (R) (high interference), and game-based (high interference). The Test of Gross Motor Development (TGMD-2) was used to assess four tasks [overhead throw (OT), underhand throw (UT), catch (C), and throwing to a target]. The test was administered on four occasions: during pre-test, post-test, retention, and transfer. The results showed that the R group outperformed all the other groups in the post-test and the retention test. Meanwhile, in the transfer test, both R and Game-Based groups performed better than the B and GI groups. There were no differences between the R and Game-Based groups during transfer. Practicing TCG skills according to a random order was better for the acquisition and learning of GMS. The CI effect was evident, whereby high interference practice schedules were superior to low and moderate interference practice schedules.
Fulltext The Effect of a 12-Week Physical Functional Training-Based Physical Education Intervention on Students' Physical Fitness-A Quasi-Experimental Study

Children have received much attention in recent years, as many studies have shown that their physical fitness level is on the decline. Physical education, as a compulsory curriculum, can play a monumental role in contributing to students' participation in physical activities and the enhancement of their physical fitness. The aim of this study is to examine the effects of a 12-week physical functional training intervention program on students' physical fitness. A total of 180 primary school students (7-12 years) were invited to participate in this study, 90 of whom participated in physical education classes that included 10 min of physical functional training, and the remaining 90 were in a control group that participated in traditional physical education classes. After 12 weeks, the 50-m sprint (F = 18.05, p < 0.001, ηp2 = 0.09), timed rope skipping (F = 27.87, p < 0.001, ηp2 = 0.14), agility T-test (F = 26.01, p < 0.001, ηp2 = 0.13), and standing long jump (F = 16.43, p < 0.001, ηp2 = 0.08) were all improved, but not the sit-and-reach (F = 0.70, p = 0.405). The results showed that physical education incorporating physical functional training can effectively promote some parameters of students' physical fitness, while at the same time providing a new and alternative idea for improving students' physical fitness in physical education.

INTRODUCTION: The Malaysian Association of Clinical Biochemists (MACB) established a Task Force for Chronic Kidney Disease. A survey was undertaken by the Task Force on the reporting of estimated glomerular filtration rate (eGFR) and urine albumin by hospital laboratories in Malaysia in both the government and private sectors.
MATERIALS AND METHODS: An e-mail invitation to participate in an online survey was sent to hospital laboratories in Malaysia (n=140). Questions regarding methods for measuring creatinine, equations for calculating eGFR, eGFR reporting, the terminology used in reporting urine albumin, types of samples and the cut-off values used for normal albuminuria.
RESULTS: A total of 42/140 (30%) laboratories answered the questionnaire. The prevalent method used for serum creatinine measurement was the Jaffé method (88.1%) traceable to isotope-dilution mass spectrometry. eGFR was reported along with serum creatinine by 61.9% of laboratories while 33.3% of laboratories report eGFR on request. The formula used for eGFR reporting was mainly MDRD (64.3%) and results were reported as exact numbers even when the eGFR was <60 ml/min/1.73m2. The term microalbumin is still used by 83.3% of laboratories. There is a large heterogeneity among the labs regarding the type of sample recommended for measuring urine albumin, reference interval and reporting units.
CONCLUSION: It is evident that the laboratory assessment of chronic kidney disease in Malaysia is not standardised. It is essential to provide a national framework for standardised reporting of eGFR and urine albumin. Recommendations developed by the MACB CKD Task Force, if adopted by all laboratories, will lead to a reduction in this variability.
Assessment of hepatotoxicity and nephrotoxicity in Cirrhinus mrigala induced by trypan blue - An azo dye

Cytotoxicity in freshwater fishes induced by industrial effluents and dyes is a global issue. Trypan blue dye has many applications in different sectors, including laboratories and industries. This study determines to detect the cytotoxic effects of trypan blue dye in vivo. The objective of this study was to estimate the sub-lethal effects of azodye in fish. Cirrhinus mrigala, a freshwater fish, was exposed to three different grading concentrations of dye 5 mg/L, 10 mg/L, and 20 mg/L in a glass aquarium. Significant (p
