Recent research has proposed that GIT2 (G protein-coupled receptor kinase interacting protein 2) acts as an integrator of the aging process through regulation of 'neurometabolic' integrity. One of the commonly accepted hallmarks of the aging process is thymic involution. At a relatively young age, 12 months old, GIT2-/- mice present a prematurely distorted thymic structure and dysfunction compa...
The presentation of thymomas is variable; most are asymptomatic and others present with local compression symptoms or a parathymic syndrome. Rarely thymomas present as an acute emergency with severe chest pain from either infarction or hemorrhage of the tumor. This rare presentation usually leads the clinician initially away from the diagnosis of thymoma. We present 4 patients who presented wit...
In order to assess the extrapulmonary effects of multiwall carbon nanotubes (MWCNT), deposition of MWCNT and histopathologic changes in lung-associated lymph nodes (LALN) were examined in MWCNT-administered rats. At the age of 13 wk, male F344 rats were intratracheally instilled with MWCNT at a dose of 0 (vehicle), 40 or 160 μg/rat. The rats were sacrificed on Day 1, 7, 28 or 91 after instillat...
Recent studies indicate that CTLA-4 interaction with B7 ligands transduces an inhibitory signal to T lymphocytes. Mice homozygous for a null mutation in CTLA-4 have provided the most dramatic example of the functional importance of CTLA-4 in vivo. These animals develop a fatal lymphoproliferative disorder and were reported to have an increase in CD4(+) and CD8(+) thymocytes and CD4(-)CD8(-) thy...
هدف: در این مطالعه به بررسی اثر تزریق کورتیکواسترویید در درمان infrapatellar fat pad syndrome در بیماران مراجعه کننده به درمانگاه ارتوپدی بیمارستان امیرالمومنین (ع) تهران در سال 1388 پرداختیم.روش مطالعه: این مطالعه به صورت یک بررسی مداخله ای (interventional) از نوع نیمه تجربی (quasi-experimental) انجام گردیده است. جامعه مورد بررسی شامل 60 نفر از افراد مبتلا به infrapatellar fat pad syndrome بود...
مقدمه : impingement syndrome یکی از بیماریهای شایع است که با درد شانه ومحدودیت حرکت در مفصل شانه همراه می باشد. با توجه به اهمیت این موضوع و لزوم دستیابی به روشی مطمئن جهت درمان مبتلایان به این بیماری، در این مطالعه به بررسی میزان اثربخشی استفاده از glyceril trinitrate بصورت موضعی در درمان مبتلایان بهimpingement syndrome پرداختیم. مواد و روشها: در این مطالعه که از نوع مداخله ای-تحلیلی میباشد60...
Primary anterior mediastinal neoplasms comprise a diverse group of tumors and account for 50% of all mediastinal masses. Thymomas are most common and can be locally invasive and associated with parathymic syndromes. Thymic carcinomas and thymic carcinoids are rare malignancies with a propensity for local invasion and distant metastases. Thymolipomas are benign thymic tumors. The mediastinal ger...
