Physical therapy intervention versus corticosteroid injection for lateral elbow tendinopathy. Does slow and steady win the race? - A systematic review.

Background: Lateral elbow tendinopathy is one of the most common chronic and degenerative diseases which significantly affects quality of life and the activities of daily living of a person. The following is a systematic review reporting a comparison between physical therapy intervention and corticosteroid injection for the treatment of lateral elbow tendinopathy. Method: PubMed, Web of Science, and Embase were searched using headings related to treatment options for Lateral elbow tendinopathy. The following keywords were used: lateral epicondylitis, physical therapy, and corticosteroid injection. Result: We descriptively analyzed and reviewed a total of 12 studies including a total of 1253 patients for lateral elbow tendinopathy. The physical therapy intervention included interventions like electrotherapy, manual therapy, and exercise. The studies included had an overall low to unknown risk of bias. Conclusion: Our review suggests corticosteroid injection provides beneficial short-term effects and physical therapy interventions provide intermediate to long-term effects, less additional treatment and low recurrence rate in patients with lateral elbow tendinopathy. Although high-quality randomized control trials are required in order to have a better understanding of both intervention types.

Selenium-Enriched Probiotic Alleviates Western Diet-Induced Non-alcoholic Fatty Liver Disease in Rats via Modulation of Autophagy Through AMPK/SIRT-1 Pathway.

Current study was aimed to investigate the ability of L.acidophilus SNZ 86 to biotransform inorganic selenium to a more active organic form, resulting in trace element enrichment. Selenium-enriched L. acidophilus SNZ 86 has been shown to be effective in the treatment of a variety of gastrointestinal illnesses, indicating the need for additional research to determine the full potential of this therapeutic strategy in the treatment of metabolic disorders. Herein, we employed the western style diet-induced model of non-alcoholic fatty liver disease (NAFLD) to explore the therapeutic effect of selenium-enriched probiotic (SP). Male Sprague Dawley rats (160-180 g) were fed a high-fat (58% Kcal of fat) and high-fructose (30% w/v) diet for 12 weeks to develop an animal model mimicking NAFLD. High-fat and High-fructose diet-fed rats exhibited hyperglycemia, hyperlipidemia, insulin resistance, abnormal liver function test, increased hepatic oxidative stress, and steatosis. SP was then administered orally (L acidophilus 1 × 109 CFU/ml containing 0.4 g Se/day; p.o.) for 8 weeks. The selenium enrichment within L. acidophilus SNZ 86 was validated by TEM, which allowed for visualisation of the selenium deposition and size distribution in the probiotic. In NAFLD control rats, the expression of autophagy proteins (LC-3 A/B and Beclin), AMPK, and SIRT-1 was significantly reduced indicating downregulation of autophagy. However, supplementation of SP ameliorates hepatic steatosis as evidenced by improved biochemical markers and autophagic activation via upregulation of the AMPK and SIRT-1 pathway showing the relevance of autophagy in the disease aetiology. Collectively, these findings provide us with a better understanding of the role of SP in the treatment of hepatic steatosis and establish a therapeutic basis for potential clinical application of SP in the prevention of NAFLD and associated pathological conditions.

OsCPK29 interacts with MADS68 to regulate pollen development in rice.

Pollen development and its germination are obligatory for the reproductive success of flowering plants. Calcium-dependent protein kinases (CPKs, also known as CDPKs) regulate diverse signaling pathways controlling plant growth and development. Here, we report the functional characterization of a novel OsCPK29 from rice, which is mainly expressed during pollen maturation stages of the anther. OsCPK29 exclusively localizes in the nucleus, and its N-terminal variable domain is responsible for retaining it in the nucleus. OsCPK29 knockdown rice plants exhibit reduced fertility, set fewer seeds, and produce collapsed non-viable pollen grains that do not germinate. Cytological analysis of anther semi-thin sections during different developmental stages suggested that pollen abnormalities appear after the vacuolated pollen stage. Detailed microscopic study of pollen grains further revealed that they were lacking the functional intine layer although exine layer was present. Consistent with that, downregulation of known intine development-related rice genes was also observed in OsCPK29 silenced anthers. Furthermore, it has been demonstrated that OsCPK29 interacts in vitro as well as in vivo with the MADS68 transcription factor which is a known regulator of pollen development. Therefore, phenotypic observations and molecular studies suggest that OsCPK29 is an important regulator of pollen development in rice.

Immunomodulatory nanosystems for treating inflammatory diseases.

Inflammatory disease (ID) is an umbrella term encompassing all illnesses involving chronic inflammation as the central manifestation of pathogenesis. These include, inflammatory bowel diseases, hepatitis, pulmonary disorders, atherosclerosis, myocardial infarction, pancreatitis, arthritis, periodontitis, psoriasis. The IDs create a severe burden on healthcare and significantly impact the global socio-economic balance. Unfortunately, the standard therapies that rely on a combination of anti-inflammatory and immunosuppressive agents are palliative and provide only short-term relief. In contrast, the emerging concept of immunomodulatory nanosystems (IMNs) has the potential to address the underlying causes and prevent reoccurrence, thereby, creating new opportunities for treating IDs. The IMNs offer exquisite ability to precisely modulate the immune system for a therapeutic advantage. The nano-sized dimension of IMNs allows them to efficiently infiltrate lymphatic drainage, interact with immune cells, and subsequently to undergo rapid endocytosis by hyperactive immune cells (HICs) at inflamed sites. Thus, IMNs serve to restore dysfunctional or HICs and alleviate the inflammation. We identified that different IMNs exert their immunomodulatory action via either of the seven mechanisms to modulate; cytokine production, cytokine neutralization, cellular infiltration, macrophage polarization, HICs growth inhibition, stimulating T-reg mediated tolerance and modulating oxidative-stress. In this article, we discussed representative examples of IMNs by highlighting their rationalization, design principle, and mechanism of action in context of treating various IDs. Lastly, we highlighted technical challenges in the application of IMNs and explored the future direction of research, which could potentially help to overcome those challenges.
