Background: Mobilization with movement (MWM) is an effective intervention for increasing range of motion (ROM) and function without pain. Objectives: The purpose of this study is to comprehensively characterize the functional effects of MWM applied to the ankle joint in patients with stroke. Design: Systematic Review and Meta-analysis. Methods: International electronic databases, CINAHL, Embase, MEDLINE, PubMed, and Google scholar were included and identified after review by two investigators in July 2023 according to PRISMA guidelines. Data were synthesized using software provided by Cochran and analyzed using a random effects model with reweighting to account for heterogeneity between participants. Results: After excluding duplicate studies, 14 of the 19 articles screened through the abstracts were excluded, resulting in a total of five studies involving 109 participants with stroke. MWM showed significant differences in ankle ROM [overall effect (Z=3.27, P=0.00)], gait speed [overall effect (Z=3.33, P=0.00)], and cadence [overall effect (Z=2.49, P=0.01)]. Conclusion: The results of the meta-analysis confirmed that MWM is effective in improving ankle ROM and gait parameters in patients with stroke.

Background: Short foot exercise, which is an intrinsic foot muscle exercise proposed by the foot core system, is used to improve the strength of intrinsic foot muscles and sensory input and function of the foot. However, there is a lack of studies that assessed the improvement in foot function after short foot exercise in patients undergoing rehabilitation after a modified Broström operation of the ankle joint. Objectives: To investigate the effects of short foot exercise on intrinsic foot muscle cross-sectional area and balance ability in patients who had undergone a modified Broström operation of the ankle joint. Design: A single blind, randomized controlled trial. Methods: Sixteen patients who were undergoing ankle rehabilitation exercises following the modified Broström operation were randomized into two groups. General physical therapy, short foot exercises, and ankle rehabilitation programs were performed in the experimental group (n=8), whereas general physical therapy and ankle rehabilitation programs were performed in the control group (n=8). For outcome measures, the intrinsic muscles of the foot were imaged using the Sonimage HS1 musculoskeletal ultrasound system. The Y-balance test and RS-foot scan system were used to confirm dynamic balance ability and static balance ability. Results: The cross-sectional area of the abductor hallucis and dynamic balance ability significantly improved in the experimental group that underwent short foot exercise compared to the control group (P<.05). In contrast, static balance ability was not significantly different between the two groups (P>.05). Conclusion: Short foot exercise successfully increased the cross-sectional area of the abductor muscle and improved dynamic balance after a modified Broström operation

Background: Incorrect postures of adolescents caused by the use of smart devices have been noted as a factor causing spinal diseases. Objectives: To examine the effect of joint mobilization and stretching on Cobb’s angle and respiratory function in adolescent idiopathic scoliosis (AIS). Design: Cluster-randomized controlled trial. Methods: A total of 22 subjects with AIS were enrolled. They were allocated to two groups: the joint mobilization (n=11) and the stretching (n=11). All interventions were conducted for 30 minutes, three times a week for six weeks. Outcome measures were the Cobb’s angle and respiratory function. The Cobb’s angle and respiratory function measured using the X-ray and Micro- Quark. Results: Joint mobilization group showed significant differences in Cobb’s angle and respiratory function, but stretching group showed significant differences Cobb’s angle. The differences in peak expiratory flow (PEF) between the two groups were significant. Conclusion: This study proved that joint mobilization is a more effective intervention for AIS to improve Cobb’s angle and respiratory function, when compared to stretching.

Background: Adults with forward head posture (FHP) often suffer from thoracic hyperkyphosis and thoracic dysfunction, and including reduction of the craniovertebral angle (CV angle) and tightening of the superficial neck muscles. In order to treat thoracic dysfunction, interventions aimed at improving thoracic mobility are necessary. Objectives: To examine the effects of maitland manual mobilization therapy on the thoracic spine in adults with FHP. Design: Single-blind randomized controlled trial. Methods: Thirty adults with FHP who met the selection criteria were randomized to the thoracic multiple joint mobilization (TMJM; n=15) group and the thoracic general joint mobilization (TGJM; n=15) group. Joint mobilizations were performed for 23 minutes a day for 4 weeks continuously, two times per week. Outcome measures were ImageJ, BTS FREE EMG 1000, neck disability Index (NDI). Results: Although changes in the left sternocleidomastoid muscle activity and NDI scores over time between the two groups differed, other variables were noted only changes observed over time. Muscle activity in the right sternocleidomastoid increased again in the TGJM group post-intervention and 2 weeks after the end of the experiment, but changes in other variables were retained or improved, confirming the lasting effects of thoracic joint mobilization. Conclusion: Thoracic multiple joint mobilization may be recommended as a more effective intervention for adults with FHP.

Background: Patients with stroke have core muscle weakness and limited rib cage movement, resulting in restrictive lung disease. Objectives: To examine the comparison of effects of rib cage joint mobilization combined with diaphragmatic breathing exercise and diaphragmatic breathing exercise on the pulmonary function and chest circumference in patients with stroke. Design: A cluster randomized controlled trial. Methods: Twenty-four patients were randomly assigned to an experimental group (rib cage joint mobilization combined with diaphragmatic breathing exercise group) and control group (diaphragmatic breathing exercise group). Patients in the experimental group underwent rib cage joint mobilization for 15 min and diaphragmatic breathing exercise for 15 min. The control group underwent diaphragmatic breathing exercise for 30 min. Both groups underwent exercise thrice a week for 4 weeks. The pulmonary function and chest circumference were measured using the MicroLab spirometer and a tape measure, respectively. Results: After the intervention, the pulmonary function and chest circumference significantly improved in both groups. These improvements were significantly higher in the experimental group than those in the control group. Conclusion: Rib cage joint mobilization combined with diaphragmatic breathing exercise improves pulmonary function and chest circumference in patients with stroke.

Many countries have implemented genetic evaluation for fertility traits in recent years. In particular, reproductive trait is a complex trait and need to require a system-level approach for identifying candidate genes related to the trait. To find the candidate gene associated with reproductive trait, we applied a weighted gene co-expression network ana-lysis from expression value of bovine genes. We identified three co-expressed modules associated with reproductive trait from bovine microarray data. Hub genes (ZP4, FHL2 and EGR4) were determined in each module; they were topologically centered with statistically significant value in the gene co-expression network. We were able to find the highly co-expressed gene pairs with a correlation coefficient. Finally, the crucial functions of co-expressed modules were reported from functional enrichment analysis. We suggest that the network-based approach in livestock may an important method for analyzing the complex effects of candidate genes associated with economic traits like repro-duction.

The effects of β-lapachone on gastric secretion were investigated. The pylorus of male Sprague-Dawley rats was ligated and intraduodenally injected with β-lapachone, and the volume, pH, free HCl, and total acidity of gastric fluid were measured 6 hours after the operation. Treatment with β-lapachone resulted in dose-dependent inhibition of gastric secretion Gastric fluid was reduced to 42.9% of control level by 100 mg/kg of β-lapachone, leading to an increase of pH to 6.70 from 1.85 in the control group. In parallel with the increase of pH, at this dosage, free HCl and total acidity decreased to 16.7% and 12.0%, respectively, of control levels. β-Lapachone exhibited ED50 values of 72, 46, and 47 mg/kg for inhibition of gastric volume, free HCl, and total acidity, respectively, implying a superior efficacy on gastric acid to volume. In comparison, pantoprazole (30 mg/kg) reduced the volume, free HCl and total acidity of gastric fluid to 53.0%, 26.0%, and 25.0%, respectively, of control levels, resulting in an increase in pH to 6.36. In the current study, it was confirmed that β-lapachone at an appropriate dose (100 mg/kg) exerted a higher inhibitory effect on gastric secretion than pantoprazole (30 mg/kg), a well-known proton-pump inhibitor. Therefore, it is suggested that β-lapachone could be a candidate compound for prevention or treatment of gastric ulcers induced by diverse psychological and physical stimuli.

Effects of carnitine on atherosclerosis and steatosis of hypercholesterolemic rabbits induced by a high-cholesterol diet (HCD) containing 0.5% cholesterol and 2.0% corn oil were investigated. Male New Zealand white rabbits with hypercholesterolemia (blood cholesterol 1,000-1,500 mg/dl) induced by two-week feeding a HCD, were fed a HCD containing 0.008 or 0.075% L-carnitine for an additional eight weeks. Feeding a HCD for 10 weeks resulted in severe atheromatous change, covering 55.7% of the aortic walls, in addition to profound hepatic steatosis. However, carnitine supplementation resulted in recovery of the increased low-density lipoproteins and triglycerides and a decrease in the levels of high-density lipoproteins following HCD feeding, although the increased cholesterol concentration was not potentially attenuated. Notably, carnitine induced a marked reduction of the atheroma area and hepatic lipid accumulation as well as lipid peroxidation. The results of this study indicated that carnitine exerted anti-atherosclerotic and fatty liver-preventing activities through blockade of lipid peroxidation and regulation of lipid metabolism.
