BACKGROUND Musculoskeletal (MSK) conditions are the most frequently reported chronic conditions and one of the biggest causes of disability in the UK. Given the ageing population and the impact of these problems, the demand for MSK treatment will rise. Despite reduced waiting times, MSK pathways have remained variable and inconsistent and need to be improved to meet patient needs. The aim of th...
OBJECTIVES To assess the consultation prevalence of musculoskeletal (MSK) conditions as presented in different healthcare systems, and to determine the feasibility of comparing prevalence figures between nations. METHODS The settings were an English regional database (Consultations in Primary Care Archive (CiPCA)) and the Swedish Skåne County Health Care Register. Case definitions, data extra...
BACKGROUND The rheumatologist relies heavily on clinical skills to diagnose diverse conditions, something that is correlated with one's knowledge of clinical anatomy. More recently, rheumatology has offered further career flexibility with opportunities to develop skills such as joint injection and musculoskeletal (MSK) ultrasound, both of which require a sound understanding of anatomy. Currentl...
در این مقاله با قرار دادن مدولاتور الکترو اپتیکی در کاواک خارجی یک لیزر نیمرسانا و مدوله کردن پسخوراند اپتیکی، تغییرات دینامیک شدت خروجی لیزر مورد مطالعه قرار گرفته است. این امر به وسیله نمودارهای دوشاخه شدگی و تحول زمانی نسبت به پارامترهای ضریب دامنه مدولاسیون اعمال شده و فرکانس ولتاژ مدولاسیون مربوط به مدولاتور الکترو اپتیکی به صورت عددی مورد آنالیز قرار گرفته است. در این مطالعه نشان دادیم ک...
مبدلهای چند سطحی با تولید تعداد سطوح زیاد در ولتاژ خروجی قادر به تولید ولتاژهای AC با کیفیت بالا و THD کم میباشند. از این رو میتوان آنها را بعنوان ولتاژ ژنراتورهای با کیفیت در کاربردهای شبکه و سیستمهای درایو به خوبی بکار گرفت. تاکنون تعداد زیادی تکنیکهای مدولاسیون جدید بمنظور پشتیبانی از رشد فزاینده توپولوژیهای مبدلهای چند سطحی معرفی شدهاندکه هر کدام از این روشها دارای مزایا و معایب خا...
The commonly used submarine optical fiber communication system is expected to provide long-distance reliable signals transmission. We present a novel using minimum shift keying (MSK) encoded downstream signals. 10Gb/s MSK coded are successfully transmitted over the 100km single-mode (SMF).The spectrums, eye-diagrams and bit error rate (BER) before after transmission of in were measured analyzed...
The article reviews the major challenges related to the principles of the correct technique of musculoskeletal ultrasound (MSK US). All the crucial aspects of correct MSK soft tissue diagnosis have been discussed, including equipment settings, use of recent image software innovations and ultrasound standoff pads, and correct transducer positioning. The importance of the fundamental principles o...
BACKGROUND Musculoskeletal (MSK) pain is one of the most predominant types of pain and accounts for a large portion of the primary care workload. AIM To systematically review and integrate the findings of qualitative research to increase understanding of patients' experiences of chronic non-malignant MSK pain. DESIGN AND SETTING Synthesis of qualitative research using meta-ethnography using...
MSK (mitogen- and stress-activated protein kinase) 1 and MSK2 are kinases activated downstream of either the ERK (extracellular-signal-regulated kinase) 1/2 or p38 MAPK (mitogen-activated protein kinase) pathways in vivo and are required for the phosphorylation of CREB (cAMP response element-binding protein) and histone H3. Here we show that the MSKs are involved in regulating the transcription...
