A single-blinded, randomized, and controlled trial was done successfully. Sixty venous ulcer patients were divided randomly into three groups; Group (A): control group, Group(B): High-TENS group, and Group(C): Low-TENS group. Group (A), contains twenty participants who received routine medical care and dressing. As for group (B), includes twenty participants who obtained high-frequency TENS; Frequency (80-120) HZ, Intensity (15 - 30 amp), Pulse duration 250 Micro sec, 60 min per session with routine medical care and dressing. The third group (c) L-TENS, encompasses twenty participants who received low-frequency TENS (1-5) HZ; Intensity (30 -80 amp), Pulse duration 250 Micro sec, 60 min per session with routine medical care and dressing. All the participants were examined before and after two months of intervention; four weeks (post1), then after eight weeks (post2). Participants were examined by using (image j) to measure the ulcer area. Saline was used for measuring the ulcer volume, and a visual analog scale was adopted to evaluate pain. After drawing a comparison among the three groups after four weeks and after eight weeks of treatment, a statistically significant decrease (P <0.05) in wound surface area, wound volume, and pain in favor of L-TENS was noticed. It has been found that L- TENS is more effective than H -TENS and is highly recommended in the treatment protocol for such debilitating conditions.","PeriodicalId":48702,"journal":{"name":"Physical Review a","volume":"92 1","pages":"376-382"},"PeriodicalIF":2.6,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83785209","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our model is wholly probabilistic and shows that the number of the ultracold atoms remaining in the trap as a function of time is non-exponential. We update the recent results of a comparison between a traditional pressure standard-a combined flowmeter and dynamic expansion system-to the CAVS [D.S. Barker, et al., AVS Quantum Science 5 035001 (2023)] to reflect the results of our model. We find that the effect of glancing collisions shifts the theoretical predictions of the total loss rate coefficients for 7Li colliding with noble gases or N2 by up to 0.6 %.

ES has been accepted usually as an idiopathic condition, but it may be secondary. The coexistence of autoimmune cytopenias and Hodgkin lymphoma (HL) is rarely observed and the rate of ES in HL patients is not clear. Here we describe a 56-year-old male patient who presented with ES and was diagnosed with HL. After corticosteroids, intravenous immunoglobulin (IVIG) and ABVD (doxorubicin, bleomycin, vinblastine, dacarbazine) treatment, immune cytopenias were completely resolved. The literature is also reviewed and we found 16 cases in which HL and ES coexist. Although AIHA and immune thrombocytopenia usually develop simultaneously, they rarely occur at different times. Many aspects of the pathogenesis are unknown, but it is thought to be a complex immunological background. Corticosteroids and/or IVIG are the most commonly used first-choice drugs in the initial treatment of ES. Response rates to treatment are variable and response to treatment may be poor, particularly with underlying conditions.

We find that regions use civic capital to leverage new, technological windows of opportunity, but they do so in very different ways. Tracing Toronto's evolution from a marketing hub for foreign multinationals into a centre for entrepreneurship, we illustrate how weak ties and cross-sectoral buzz created a 'super connector', scaling high-technology firms in a wide variety of areas. In Ottawa, task-specific cooperation in R&D, education and specialised infrastructure enabled the region to overcome the disadvantages of its small size as a 'specialist' in a single, capital-intensive niche, telecommunications equipment. Finally, entrepreneurs in Waterloo eschewed task-specific cooperation for peer-to-peer mentoring. By diffusing generic knowledge about how to circumvent the liabilities of smallness, mentoring networks enabled this 'scrapper' city to support smaller start-ups in a broad range of niches.","PeriodicalId":48702,"journal":{"name":"Physical Review a","volume":"90 1","pages":"549-566"},"PeriodicalIF":4.7,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10830395/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84318412","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Approximately 90% of SSc patients develop interstitial lung disease (ILD), and it is the leading cause of morbidity and mortality. Further understanding of immune-mediated fibroproliferative mechanisms has the potential to catalyze novel treatment approaches in this difficult to treat disease.Recent findings: Recent advances have demonstrated the critical role of aberrant innate immune activation mediated by mitochondrial DNA (mtDNA) through interactions with toll-like receptor 9 (TLR9) and cytosolic cyclic guanosine monophosphate-adenosine monophosphate synthase (cGAS).Summary: In this review, we will discuss how the nature of the mtDNA, whether oxidized or mutated, and its mechanism of release, either intracellularly or extracellularly, can amplify fibrogenesis by activating TLR9 and cGAS, and the novel insights gained by interrogating these signaling pathways. Because the scope of this review is intended to generate hypotheses for future research, we conclude our discussion with several important unanswered questions.","PeriodicalId":48702,"journal":{"name":"Physical Review a","volume":"70 1","pages":"204-220"},"PeriodicalIF":0.0,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10791121/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84228806","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Following treatment, it may take many months for the tumour to respond and it may initially enlarge. We reviewed our PBT patients to determine when they showed a radiological response to treatment.Methods: Patients undergoing PBT for ciliary body or choroidal melanomas between 2008 and 2018 were included. Data were collected on patient demographics, treatments before and after PBT and survival. All ultrasound investigations prior and since PBT were reviewed and tumour volume calculated using a validated formula for a half-ellipsoid shape.Results: 193 patients were analysed, 169 with choroidal and 24 with ciliary body melanomas. 31.6% patients had other treatment prior to PBT. At a mean of 8 months post-PBT, 64.7% of patients had a reduced tumour volume with 20.2% having larger tumours. At a mean of 15 months post-treatment, these figures were 67.8% and 10.3%. 18.1% of patients had an enucleation during the study period. The earliest responses were seen at 2 months, the latest at 32 months post-treatment. 5-year melanoma-specific survival was 82.3%.Conclusions: In our study, by 6 months post-PBT, a majority of patients show a reduction in tumour volume. Of those that do not, many respond in the next 6 months and a response may be seen up to 32 months after treatment. Patients may need to be monitored for up to 32 months to see a final response to PBT treatment.","PeriodicalId":48702,"journal":{"name":"Physical Review a","volume":"67 1","pages":"130-137"},"PeriodicalIF":2.6,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10712970/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84057557","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
