Marks RayCorresponding author

Osteoarthritis, the most prevalent joint disease and one affecting many aging adults is strongly associated with various degrees of disability and high health costs. Commonly deemed largely incurable and progressive, it appears muscle fat deposition and its encroachment on muscle tissue may account for multiple adverse health outcomes, especially the osteoarthritic disease process. This mini review examines whether contemporary evidence supports a role for efforts towards preventing excess fat infiltration into vulnerable muscles as one means of reducing osteoarthritic pain and disability. To this end, research on this theme and reported as of June 2025 on this issue was sought. We found that with few exceptions and regardless of joint examined a role for muscle mass infiltration in osteoarthritis disability appears of high clinical significance.

Background The origin of osteoarthritis, the most common disabling disorder of older adults remains uncertain. Aim This mini review examines the possible role played by various neuromuscular deficits in the osteoarthritis etiopathogenic process. Methods and Procedures Articles that haveaddressed the current topic of interest and were located in the PUBMED,Google Scholar, and Web of Science electronic data bases as of 2017-2022 were carefully sought and examined. Results Various neuromuscular mechanisms may have a bearing on the development and progression of osteoarthritis, but the data are largely unrelated and observational in nature. Conclusion More research to examine this issue is sorely needed and could have considerable merit in light of the growing populations of older adults at risk for disabling osteoarthritis in the face of few intervention options to help them to achieve an optimal functional level.

Dose Body Mass Index (BMI) Fit to Muscular Individual?

Body mass index (BMI) seemingly is an important scale for the body types determination in individual with different ethnicity. Accordingly, individual with BMI< 18.5 are classified as slim or underweight and people with BMI between 18.5 -24.9 are called normal body types. Subsequently, those individual with BMI between 25-29.9 are categorized as overweight and people with BMI > 30 are classified as obese people. Nonetheless, important question is where the muscular individual are located in this BMI scale ? Macular induvial also called overweight or obese in BMI scale which can create kind of confusion for induvial because the might try to lose weight whilst they do not actually need it. Thus ,it seems BMI measure is not sensible measure for muscular induvial as otherwise the can be at risk of health problems in various ways. Uses of the another apparatus such an ordinary weight scale or computational devices which could estimate the body type according to the BMI more accurately can be helpful.

Study Design: Prospective study, simple crossover design. Background: Proprioception is a cornerstone for maintaining joint and postural stability. Dynamic stability is particularly emphasized within these components. This feature is important in the rehabilitation field. Therefore, the quest for elements to improve these values ​​can bring advantages in sports. Objectives: Evaluate if there are advantages in the performance of a Star Excursion Balance Test (SEBT) using Kinesio taping. Methods: We evaluated 10 professional soccer players from the Chilean women’s national team. They were randomly divided into 2 groups. One group had Kinesio taping and their SEBT performance was evaluated. The other group performed the measurements without the use of Kinesio Taping. Afterward, each group performed the evaluation they did not do during the first stage. We then compared the performance achieved with and without the use of Kinesio Taping Results: There were significant differences in the performance achieved by the players who had the SEBT bandage applied in comparison to the players that did no. This was confirmed by using the non-parametric Wilcox test for each of the SEBT positions. Conclusions: Kinesio taping has positive implications in the SEBT. We can extrapolate that its use can improve the dynamic balance and thus become an important pillar in sports rehabilitation.

Physiological changes in musculature allow widespread movements in human body. Correspondingly, varying in muscle prototypes characterise direct different training paradigms in therapeutics practice or can governs athletic performances. Mode of muscle contraction type are isometric, concentric or eccentric. Great examples of concentric exercise are walking- up-hill, stair ascent and lifting a dumbbell in bicep curl or pushing a bar up. Examples of eccentric muscle actions are walking - down-hill, satire decent and, isokinetic arm and leg extensions. During isometric muscle contraction the length of muscle does not change while muscle exert force .This type of movement can be seen while a person performs a maximal voluntary contractions (MVCs).Eccentric exercises increasing the concentric and isometric contraction as well. Performing the eccentric muscle contraction in daily life enhance quality of life and lifespan due to increasing muscle strength with low cost of energy consuming and thus it can apply in variety of domains. A simple walking task such as downhill - walking (i.e. 30 min) can provide the aforementioned conditions.

Second-generation antipsychotics have relatively recently become available in long-acting intramuscular formulations (LAIs) and have been receiving a substantial amount of pharmaceutical industry promotion on the grounds that they improve treatment adherence in patients with psychotic illness. LAIs do have some drawbacks, however, which is the topic area covered by this review. A Global Scholar search of the nursing and medical literature reveals several factors that can negatively impinge on the clinical efficacy of LAIs: 1. The extent of training of injection personnel 2. The quality of surveillance of patient symptoms and side effects 3. The skilled use of the full range of injection techniques 4. The extent of drug accumulation over time 5. The potential loss of drug dose flexibility 6. The impact of exercise and temperature on drug distribution 7. The burden of the medication routine and the social burdens of LAIs 8. The safety of LAIs during pregnancy 9. The perceived coerciveness of LAIs 10. Issues of overdose and polypharmacy 11. Issues of cost 12. The important issue of responsibility for self-management of illness. Although the evidence is clinical and anecdotal, LAIs appear to work well for many patients, but their drawbacks are not negligible. Clinicians need to weigh individual risks and benefits when making treatment decisions.

Mucosa-Muscular Signaling for Bile-Induced Esophageal Dysmotility. An Experimental Study in Ex-Vivoguinea-Pig Isolated Esophagi

A. M. Herbella FernandoCorresponding author Department of Surgery, Escola Paulista de Medicina, Federal University of Sao Paulo, São Paulo, Brazil

Background/Aims: Esophageal motor abnormalities are frequently found in patients with gastroesophageal reflux disease. The effect of bile in esophageal dysmotility is probably secondary to mucosal signaling to the muscular layer and not a transmural process. This study aims to identify the mucosa-muscular signaling path by receptors blockage in an experimental study. Methods: Fifteenguinea pig esophagi were isolated and ex-vivo esophageal contractility was assessed with force transducers. The esophagi were incubated in 100 µM ursodeoxycholic acid for 1 hour and 5 sequential contractions induced by 40 mM KCl spaced by 5 minutes were measured. After 30 minutes, esophagi specimens were incubated in 3 different smooth-muscle contraction antagonists: atropine (1µM) in 5, suramin (1µM) in 5 and genistein (1µM) in 5. The same protocol for contractions was repeated. Values are expressed as mean ± standard deviation and encompass the mean of five stimuli. Experimental procedures were approved by the University Institutional Review Board. Results: Contraction amplitudes after bile incubation but before antagonist incubation were 1.6±0.6 g, 1.2±0.8 g, and 1.2±0.4 g for atropine, suramin and genistein, respectively. Mean contraction amplitudes after antagonists instillation were 1.2±0.6 g, 1.4±0.5 g, 0.9±0.2 g, respectively. There was no different in contraction amplitude before and after instillation of atropine (p=0.188), suramin (p=0.488) or genistein (p=0.079). Conclusion: Our results show that blockage of cholinergic (atropine), purinergic (suramin) or tyrosine kinase (genistein) paths do not change esophageal dysmotility induced by bile. Other molecular path may play the role in this scenario.

Diabetic Mouse Delayed Wound Model Following Treatment with the NerveStim™ Neuropathy System

Apr 2026 DOI 10.14302/issn.2640-6403.jtrr-26-6077
Kalmeta MargaretCorresponding author

Delayed wound healing in diabetes is characterized by impaired angiogenesis, persistent inflammation, extracellular matrix dysregulation, and peripheral neuropathy. A preclinical study was conducted using a diabetic mouse delayed wound model to evaluate the surrounding tissue of a wound, (its periwound) and its tissue responses following treatment with the NerveStim™ Neuropathy System, a combination topical gel and neuromuscular electrical stimulation platform. Periwound tissue was harvested at Day 14 and analyzed using NanoString gene expression profiling. Treated animals demonstrated visibly increased periwound tissue thickness compared to untreated controls. Differential expression analysis identified 76 significantly upregulated and 17 downregulated genes. Upregulated pathways included angiogenesis (Vegfa, Fgf2, Pdgfb, Nos3), neurotrophic signaling (Ngf, Bdnf, Scn9a, Trpv1), macrophage polarization (Arg1, Mrc1, Il10), and extracellular matrix remodeling (Col1a1, Col3a1, Mmp9, Timp1). Downregulation of select pro-inflammatory mediators (Nos2, Mif) was observed. These coordinated transcriptional changes are consistent with activation of reparative immune, neurovascular, and matrix remodeling pathways in diabetic periwound tissue.

Acute Hypomagnesemia-Induced Cerebellar Down-Beat Nystagmus Syndrome Due to Benign Paroxysmal Positional Vertigo: A Case Report

Marcelli VincenzoCorresponding author

Magnesium is essential for the proper functioning of all human cells and is involved in the regulation of neurotransmitter function and neurological function. Acute and chronic hypomagnesemia cause severe neurological symptoms such as neuromuscular irritability, myoclonus, stridor, dysphagia, mainly postural tremor and movement disorders along with vertical downbeat nystagmus. Here we report a case of cerebellar downbeat nystagmus syndrome induced by acute hypomagnesemia (HICS) due to very frequent vomiting in a 75-year-old woman with benign paroxysmal positional vertigo (BPPV). The clinical condition improved with daily intravenous and then oral magnesium supplementation. To our knowledge, this is the first described case of HICS induced by acute hypomagnesemia due to vomiting triggered by a benign peripheral pathology such as BPPV which was then successfully treated once the central syndrome was resolved.

Tay-Sachs Disease: From Molecular Characterization to Ethical Quandaries and the Possibility of Genetic Medicine

Tay-Sachs disease (TSD) is a rare neurodegenerative disorder caused by mutations in the HEXA gene, which encodes the ɑ subunit of the enzyme β-hexosaminidase A. Lacking this key enzyme in GM2 ganglioside catabolism, individuals who are homozygous for HEXA mutations suffer from abnormal accumulation of GM2 ganglioside in brain and nerve cells, ultimately resulting in the progressive deterioration of the central nervous system. TSD is one of three disorders characterized by β-hexosaminidase deficiency; Sandhoff disease (SD) and the AB variant arise by mutations in the HEXB and GM2A genes respectively, which disrupt other points of GM2 ganglioside degradation. Characterized by developmental delay and stagnation, muscular weakness, coordination deficits, seizures, and eventual hearing and vision loss, these three disorders are clinically indistinguishable and occur in three forms defined by age of onset. While there is a much higher incidence of TSD in the Ashkenazi Jewish population, community carrier screening and counseling initiatives have reduced disease prevalence to about the equivalent of non-Jewish populations; however, such efforts have raised ethical concerns in the Jewish community that are increasingly relevant in light of scientific and medical advancements. Currently, treatments for TSD and its related disorders focus on symptom management, with gene therapies and the application of modified CRISPR-Cas-9 technology being explored.

Some certain foods or drinks have specific effects on musculoskeletal frameworks in time of pain. For instance, the extra intake of salt declines muscular spams (or cramps) in different limbs. The regular consumptions of milk products reduce the upper or lower musculature weakness and pain. The hot drinks and foods as other examples can help to mitigate the abdominal pains. Indeed, warm drinks boost memory through lowering the pressures in different brain ‘sections (or lobs) in fatigue time. Some plant - based diets assist to the better digestion through faster and more smooth facilitation of food transformation in stomach areas. The plant – based dietary also can decline the heart muscle shocking impulse. However, some people for different reasons (i.e. cultural) do not consume some specific foods and drinks that can be kind of disadvantages for musculature system. Nonetheless, increasing the knowledge of daily food intakes can significantly help to improve musculoskeletal health in different individual in an uncertain condition.

Charcot Marie Tooth disease is a is a very chronic progressive hereditarymotor and sensory neuropathy characterized by progressive weakness andloss of touch sensation across various parts of the body. There are no curative or effective medical therapies that can ameliorate the disability associated with Charcot Marie Tooth disease. The aim of this paper is to describe the safe novel use of cerebrolysin in an Iraqi patient with Charcot Marie Tooth disease. Patients and Methods A boy who was born on the seventh of November, 2009, and was first seen on 29th of January, 2018 at the Children Teaching Hospital of Baghdad Medical City and had Charcot Marie Tooth disease was observed. He had difficulty in walking and abnormal gait that made him left first grade primary school. The nerve conduction study and electromyography study supported the clinical diagnosis of chronic symmetric sensori-motor polyneuropathy of moderated severity. The boy was treated with a safe novel therapy for one month. He receivedten doses of 3 ml intra-muscular cerebrolysin every three days. Results The short term effect of the therapy was dramatic with noticeable improvement that has never been reported before with this condition. Conclusion Further studies enrolling more patients are highly recommended.

Waldenström Macroglobulinemia (WM) is a B-cell lymphoproliferative disorder characterized mainly by uncontrolled accrual of M- immunoglobulin, secreted by malignant lymphoplasmatic cells. Mast cells interacting with malignant B-cells play an important role at the manifestation of the disease. Utilizing a previous xenotransplantation mouse model, this study evaluates long-term implant viability and quantifies distinct bone marrow mast cell populations along with their dynamics in non-WM and WM human bone implants. Non-WM bone implants were obtained from the femoral head of adult humans undergoing hip arthroplasty or hemiarthroplasty, whereas WM human bone implants originated from bone biopsies obtained from the posterior iliac crest of patients with active WM. All bone particles were implanted intramuscularly in twenty-four NOD/SCID mice. Following 3, 4 or 8 months postoperatively, xenografts were removed and studied using special histological techniques to identify mature and immature mast cells. Xenografts survived up to 8 months after implantation presenting normal cytoarchitecture (non-WM) or high-grade neoplastic infiltration and microresorption (WM bone biopsies). Statistical analysis of mast cell populations showed significant elevation regarding time progression and bone marrow microenvironment, thus suggesting the possible influence of malignant cells to the mast cell population in WM. This study presents the extended survival of intramuscular implantation of human adult bone xenografts into NOD/SCID mice and provides additional information on the interaction between mast cells and malignant B-cells.

An anterior cruciate ligament (ACL) injury is an important cause of rest in athletes. In most cases, ACL injuries do not require external contact and they are associated with biomechanical risk factors that increase ACL tension. The increase of the hip flexion angle (HF) is included within these. The ACL requires cooperation of the periarticular musculature of the knee, muscle groups, hip stabilizers and CORE muscles; consequently, fatigue caused by exercise would alter the balance and put this ligament at risk. The objective of the study is to determine the angular behavior for HF before and after a physical load (a standardized training) in children between 11 and 12 years old. A non-randomized clinical study was carried out. The sample consisted of 50 soccer school students born between 11 and 12 years old. The angular behavior of HF was compared before and after performing a training session. The angular behavior was measured through the Drop Jump test (DJ), with data obtained by inertial sensors. After the exercise, there was a significant increase in HF. It was concluded that the angular behavior of HF increases significantly in both extremities after training and that preventive measures must be applied for neuromuscular control of the hip.

Objective: Use "The 11 +" warm-up program in female players of the National Chilean Sub-17 Football team in order to analyze morpho – physiological variables. The implementation of this training program will generate morpho – physiological changes between players exposed. Federation International Football Association (FIFA) created a training program known as the "11+", designed to amend morpho-functional parameters such as lower extremity alignment, strength, intra, and inter muscular coordination and balance, among others. Subjects: Information indicates that injuries are a serious cause of concern for the soccer clubs and therefore, it is necessary to introduce the prevention programs. Methods: 20 female players of the National Chilean Sub-17 Soccer Team, from 14 to 17 years, who trained from March 2017 to January 2018. The “The 11+” warm-up program was considering an independent variable and thigh circumference, jumping ability, speed and balance are considered dependent variables. We use The STATA 11.1 SE (Statistics / Data Analysis) program for the statistical. Results: After implementing the “The 11+” program, significant changes (p < 0.05) were observed in the morphological variables of thigh circumference and functional speed. Concerning the functional variables of jump and balance, favorable but not statistically significant. Conclusions: Application of the "The 11 +" warm-up program for 3 months in addition to proper training, generated morpho – physiological changes associated with an increase in thigh circumference and an improvement in speed. The practical utility is to improve morpho-physiological characteristics of players in a competitive area and thereby to improve the utility of athletic performance indirectly.

Selenium is an essential micronutrient required for healthy metabolism, as well as prevention, and treatment of selenium deficiency diseases. The experiment aimed to evaluate the influence of the Trivedi Effect®-Consciousness Energy Healing Treatment on the physicochemical and thermal properties of selenium using modern analytical techniques. The selenium sample was divided into two parts, one part of the test sample was called the control sample, while the second part of the test sample received the Biofield Treatment remotely by a renowned Biofield Energy Healer, Gopal Nayak, and was called the treated sample. The particle size values were significantly decreased by 37.69% (d10), 14.36% (d50), 4.31% (d90), and 11.58% D(43), hence, the specific surface area was significantly increased by 33.64% in the treated sample compared to the control sample. The PXRD peak intensities and crystallite sizes were significantly altered ranging from 5.23% to 100% and 75% to 111.7%, respectively; whereas 7.81% significantly decreased the average crystallite size in the treated sample than the control sample. The latent heat of fusion of the treated sample was significantly increased by 12.37% compared with the control sample.The results suggested that the Trivedi Effect® might generate a new polymorphic form of selenium which would offer better solubility, bioavailability and be thermally more stable compared with the control sample. The Biofield Treated selenium would be more useful to design novel nutraceutical/pharmaceutical formulations and might offer an enhanced therapeutic response against cardiovascular disease, cancer, neuromuscular disorders, diabetes, stress, aging, male infertility, viral diseases, degenerative ailments, etc.
