Characterization of patients with IgA nephropathy with and without associated minimal change disease
Introduction Immunoglobulin A nephropathy (IgAN) presents various clinical manifestations and pathological phenotypes. Approximately 5% of patients with IgAN present early onset nephrotic syndrome, mild mesangial lesions, diffuse foot process effacement podocytes, which resemble minimal change disease (MCD). These are defined as MCD-IgAN. Whether MCD-IgAN is a special type or simply MCD accompa...
در این پایان¬نامه، ضمن معرفی داده¬های دورافتاده و بیان اهمیت شناسایی آنها، دو روش استوار جهت شناسایی داده¬های دورافتاده چندمتغیره به نام¬های بیضی با حجم مینیمم (mve) و ماتریس کوواریانس با کمترین دترمینان (mcd) معرفی و مورد مقایسه قرار می¬گیرد. سپس با توجه به اینکه برآورد mcd نسبت به برآوردگر mve دارای نقطه فروریزش بالا، تابع نفوذ کراندار، خاصیت هم¬وردای افاین و کارایی مجانبی بالایی است، به رابط...
هدف اصلی این مقاله معرفی روشی جهت شناسایی نقاط دورافتاده در مجموعه دادههای چندمتغیره است. روش استوار به کار گرفته شده در این مقاله روش ماتریس کوواریانس با کمترین دترمینان1 (MCD) است. به علاوه به دو ویژگی مهم براوردگرهای استوار یعنی نقطه فروریزش و تابع نفوذ اشاره میکنیم. سپس به معرفی عامل سازگاری و عامل تصحیح نمونهی متناهی در براوردگر MCD خواهیم پرداخت. در پایان با ارایهی یک مثال کاربردی کا...
PURPOSE To identify CHST6 mutations in five additional Icelandic cases of macular corneal dystrophy (MCD) type I and in four families with MCD type II from Iceland. METHODS Genomic DNA was extracted from blood leukocytes of patients with MCD, their healthy family members, and from control individuals. CHST6 mutations were determined by PCR-sequencing. Immunophenotypes of MCD were determined b...
Methionine-choline-deficient (MCD) diets cause steatohepatitis in rodents and are used to study the pathophysiology of fatty liver disease in human beings. The most widely used commercial MCD formulas not only lack methionine and choline but also contain excess sucrose and fat. The objective of this study was to determine whether dietary sucrose in the MCD formula plays a role in the pathogenes...
Malonyl-CoA decarboxylase (MCD) is an enzyme involved in the decarboxylation of malonyl-CoA to acetyl-CoA. In order to explore the hypothesis that the changing plant materials’ MCD activity level can serve as therapy to diabetics, the effect of Teucrium polium compounds was studied in a diabetic rat model. In this experimental study, two groups of rats, a control and a diabetic group, each incl...
BACKGROUND Methionine-choline-deficient (MCD) diets cause steatohepatitis in rodents and are used to model fatty liver disease in human beings. Recent studies have identified sucrose as a major contributor to MCD-related liver disease through its ability to promote hepatic de novo lipogenesis. AIMS To determine whether glucose and fructose, the two constitutents of sucrose, differ in their ca...
High densities of MCD receptors were found in the stratum radiatum of Ammon's horn, the neocortex, the molecular layer of the cerebellum, colliculi and pons. Conversely areas such as the stratum lacunosum moleculare of Ammon's horn contained only low levels of MCD binding sites. The density of MCD receptors is low during the perinatal period and increases rapidly by postnatal day 10 with a decr...
BACKGROUND Acute pharmacological inhibition of cardiac malonyl coenzyme A decarboxylase (MCD) protects the heart from ischemic damage by inhibiting fatty acid oxidation and stimulating glucose oxidation. However, it is unknown whether chronic inhibition of MCD results in altered cardiac function, energy metabolism, or ischemic cardioprotection. METHODS AND RESULTS Mcd-deficient mice were prod...
Multicentric Castleman disease (MCD) is a lymphoproliferative disorder caused by human herpesvirus 8 (HHV8) infection HIV associated MCD (HIV-MCD) presents with various clinical symptoms. Many HIV-negative MCD patients are often treated with anti-human interleukin-6 (IL6) receptor monoclonal antibodies (tocilizumab), and successful results have been reported. IL-6 plays an important role in the...
