REVIEW
P W Franks, N Atabaki-Pasdar
Obesity is a risk factor for a plethora of severe morbidities and premature death. Most supporting evidence comes from observational studies that are prone to chance, bias and confounding. Even data on the protective effects of weight loss from randomized controlled trials will be susceptible to confounding and bias if treatment assignment cannot be masked, which is usually the case with lifestyle and surgical interventions. Thus, whilst obesity is widely considered the major modifiable risk factor for many chronic diseases, its causes and consequences are often difficult to determine...

Chromosome 15q11-q13.1 duplication is a common copy number variant associated with autism spectrum disorder (ASD). Most cases are de novo, maternal in origin and fully penetrant for ASD. Here, we describe a unique family with an interstitial 15q11.2-q13.1 maternal duplication and the presence of somatic mosaicism in the mother. She is typically functioning, but formal autism testing showed mild ASD. She had several congenital anomalies, and she is the first 15q Duplication case reported in the literature to develop unilateral renal carcinoma...

BACKGROUND: Spindle cell lipoma is an uncommon variant of lipoma and usually occurs as a solitary, subcutaneous, and well circumscribed lesion in the posterior neck, shoulders, and back of older men. Primary renal lipomas are rarely reported. Spindle cell lipoma in the kidney has not been previously described in the literature. CASE REPORT: A 60-year-old Chinese man suffered graft failure 10 years after living related donor kidney transplantation. During cancer surveillance, he was found to have a mass in the renal allograft, which increased in size and was suspicious for renal cell carcinoma on computerized tomographic scan...

BACKGROUND: Infections, particularly urinary tract infections, and cardiovascular accidents are the main causes of morbidity and mortality during the 1st year after kidney transplantation (KT). Bacteria and viruses, such as Escherichia coli, Enteroccoci, and Polyoma BK virus are common in the 1st 6 months, so they are controlled routinely. On the other hand, Clostridium perfringens infection is a rare life-threatening condition, associated with a high mortality rate especially in the transplant population, that is not controlled routinely...

INTRODUCTION: Along with death engraftment, in recent years, antibody-mediated damage has been identified as the leading cause of loss of kidney transplants. Despite the recognition of the role of the B-lymphocyte subpopulation in the development of both tolerance and rejection, little is known about the trigger mechanisms and effectors of this humoral response. BACKGROUND: We analyzed the relationship between B lymphocyte subpopulations and levels of B-cell-activating factor (BAFF) with the histological findings in biopsies of renal transplantation...

Mid-term date of kidney recipients with new-onset diabetes mellitus after transplantation (NODAT) was poor. We made a retrospective study of 397 patients who had living-donor kidney transplantation between January 2007 and May 2010 in our center. Pretransplantation risk factors for NODAT were identified by univariate and multivariate analyses. The mean follow-up was 53.5 ± 10.4 months. The prevalence of NODAT was 9.3%. Univariate analyses found the mean recipient age ≥40 years, body mass index (BMI) ≥24 kg/m(2), family history of diabetes, fasting blood glucose (FBG) ≥5...

BACKGROUND: Nephrotoxicity is a severe complication in patients undergoing cisplatin (CP) chemotherapy. Previous studies in our lab have shown that administration of a single dose of CP results in decrease in the activities of brush border membrane (BBM) and free radical scavenging enzymes and induces oxidative stress in rat kidney. Nigella sativa, is one of the most revered medicinal plant known for its numerous health benefits. Nigella sativa seed/oil has been shown to improve kidney functions in animal models of acute kidney injury...

Cardiovascular disease, closely related to an early appearance of hypertension, is the most common mortality cause among autosomal dominant polycystic kidney disease patients (ADPKD). The development of hypertension is related to an increase in renal volume. Whether the increasing in the renal volume before the onset of hypertension leads to a major cardiovascular risk in ADPKD patients remains unknown.Observational and cross-sectional study of 62 normotensive ADPKD patients with normal renal function and a group of 28 healthy controls...

Apoptosis inhibitor of macrophage (AIM, encoded by cd5l) is a multi-functional circulating protein that has a beneficial role in the regulation of a broad range of diseases, some of which are ameliorated by AIM administration in mice. In blood, AIM is stabilized by association with IgM pentamers and maintains its high circulating levels. The mechanism regulating the excessive accumulation of blood AIM remains unknown, although it is important, since a constitutive increase in AIM levels promotes chronic inflammation...

Regulated dicarboxylate transport is critical for acid-base homeostasis, prevention of calcium nephrolithiasis, regulation of collecting duct sodium chloride transport and the regulation of blood pressure. Although luminal dicarboxylate reabsorption via NaDC1 (SLC13A2) is believed to be the primary mechanism regulating renal dicarboxylate transport, the specific localization of NaDC1 in the human kidney is currently unknown. This study's purpose was to determine NaDC1's expression in normal and neoplastic human kidneys...

Diabetes mellitus is associated with decreased nitric oxide bioavailability thereby affecting renal blood flow regulation. Previous reports have demonstrated that cellular uptake of L-arginine is rate limiting for nitric oxide production, and that plasma L-arginine concentration is decreased in diabetes. We therefore investigated if regional renal blood flow regulation is affected by cellular L-arginine uptake in streptozotocin-induced diabetic rats. Rats were anesthetized with thiobutabarbital and left kidney was exposed...
