Background and study aim: Isometric strength exercises engage the intricate knee joint, including the femur, tibia, and patella, along with multiple muscles and ligaments, aiding in the rehabilitation of knee injuries while supporting movement and injury prevention. The specific objective of this research is to investigate the effectiveness of isometric strength exercises in rehabilitating the knee injuries among football players, assessing their impact on recovery and performance. Material and methods: Thirty male ACL Knee injured football players were randomly assigned to isometric strength exercise group (ISEG) (N=15) (Age; 20±1.9, Height;171±4.5, Weight; 60±6.0) and control group (Age;21±1.3, Height;173±4.4, Weight; 63±8.2) and their age ranged between 18 and 23. Subjects were randomly selected from various football academies in Coimbatore, Tamil Nadu, India. Thirty subjects who will diagnosed by a physiotherapist and help of orthopaedician as having knee injuries in football players and who showed a typical restriction of Range of motion (ROM). Fifteen subjects underwent rehabilitation (Isometric Strength exercise Group) and the other 15 underwent cryotreatment (Control Group). Analysis was based on the active and passive flexion Range of motion (ROM) were measured by kinovea-0.9.5 software. Means and standard deviations (±) described all data, with Shapiro-Wilk tests checking for normality (p< 0.05). A dependent 't' test determined significant mean differences between experimental and control groups (p < 0.05). Results: The participants who underwent a regimen of Isometric strengthening exercises exhibited notable enhancements in their range of motion (ROM), highlighting the effectiveness of this comprehensive approach significantly improved in active and passive flexion Range of motion (p < 0.05). Conclusion: Isometric strength exercises demonstrate promise in enhancing knee rehabilitation outcomes among football players, warranting further exploration and implementation compared to control group.

Background and study aim: Plyometric training is widely acknowledged as an effective option for athletes to attain improved physical performance. A variety of exercises involving the lower limb's stretch-shortening cycle can be used for plyometric training. Numerous studies have examined the impact of plyometric training on various outcomes in various populations over the past few decades. Objective: This study set out to ascertain how a six-week plyometric training programme affected the development of speed-strength fitness measurements in male team handball athletes. Material and methods: Total of thirty intercollegiate level team handball athletes were randomly assigned to 2 groups i.e. plyometric training group with an average age of 20.7 ± 0.7 years, height of 175.3 ±4.2, weight of 75.1 ± 4.1 and BMI of 24.43 ± 0.97; control group with an average age of 20.8 ± 0.7, height of 175.1 ± 4., weight of 74.9 ± 3.1 and BMI of 24.47 ± 1.37. The linear sprint (10 m and 30 m), standing long jump (SLJ), and change of direction sprint (CODS) were evaluated before and after the intervention for thirty male team handball athletes who were randomly assigned to either the plyometric training group (PTG) (n = 15) or the control group (CG) (n = 15). Results: Within group changes were analyzed using paired t-test. The significant differences obtained between the tests in all dependent variables. Conclusion: When it comes to linear sprints, standing long jumps, and change of direction sprints, plyometric training works better than CG. Consequently, adding either plyometric training or sport-specific training to an athlete's regimen may help male team handball players achieve greater speed-strength fitness.

Plants respond to the environmental cues in various ways, recent knowledge of RNA interference in conferring stress tolerance had become a new hope of developing tolerant varieties. Here we attempt to unfold the molecular mechanism of stress tolerance through miRNA profiling and expression analysis in Finger millet (Eleusine coracona) under salt and drought stress conditions. The expression analysis of 12 stress specific conserved miRNAs was studied using semi-quantitative real time PCR and Northern blot assay. Our studies revealed that, although most of the miRNAs responded to the stresses, the expression of particular miRNA differed with the nature of stress and the tissue. The expression analysis was correlated with the existing data of their target genes. Abiotic stress up-regulated miRNAs are expected to target negative regulators of stress responses or positive regulators of processes that are inhibited by stresses. On the other hand, stress down-regulated miRNAs may repress the expression of positive regulators and/or stress up-regulated genes. Thus the current study of miRNAs and their targets under abiotic stress conditions displays miRNAs may be good candidates to attribute the stress tolerance in plants by transgenic technology.

In order to identify the components of high temperature response in French bean, three heat shock proteins induced under high temperature were purified to homogeneity by Carboxy methyl cellulose and sephadex G-100 chromatography followed by preparative SDS-PAGE. Two of these, Hsp1 and Hsp3 were further characterized by immuno-detection with polyclonal antibodies. Hsp3 exhibited ATPase and chaperone activity with malate dehydrogenase and citrate synthase. Partial cDNA for Hsp3 synthesized using the primer derived from amino-terminal sequence was cloned and expressed in Escherichia coli. The recombinant protein possesses ATPase activity, and showed thermal protection at 50°C in Escherichia coli. The translated partial cDNA showed homology with stress induced proteins including ATPases from higher plants. These results supported the fact that French bean response to high temperature stress involves Hsps as one of the principal components.
