Epstein-Barr virus (EBV) is a ubiquitous gamma-herpesvirus that is highly prevalent in almost all human populations, and is associated with many human cancers such as nasopharyngeal carcinoma (NPC), Hodgkin's disease, and gastric carcinoma. However, in these EBV-associated cancers, only NPC exhibits remarkable ethnic and geographic distribution. We hypothesized that EBV genomic variations might contribute to the pathogenesis of different human cancers in different geographic areas. In this study, we collected 18 NPC biopsies from the Hunan Province in Southern China and de novo assembled 18 NPC biopsy specimen-derived EBV (NPC-EBV) genomes, designated as HN1 to HN18...

BACKGROUND: Blood pressure control is an essential therapy for patients with acute type B aortic dissection (ABAD) and should be maintained throughout the entire treatment. Thus, vast majority current guidelines recommend control the blood pressure to lower than 140/90 mmHg. Theoretically, a much lower target may further decrease the risk of propagation of dissection. However, some argued that too lower blood pressure would compromise the organ perfusion. Thus, there is no unanimous optimal target for blood pressure in patients with ABAD so far...

Despite varied etiologies and symptoms, several neurodegenerative diseases-specifically, Alzheimer's (AD), Parkinson's (PD), and Huntington's diseases (HDs)-share the common feature of abnormal circadian rhythms, such as those in behavior (e.g., disrupted sleep/wake cycles), physiological processes (e.g., diminished hormone release) and biochemical activities (e.g., antioxidant production). Circadian disturbances are among the earliest symptoms of these diseases, and the molecular mechanisms of the circadian system are suspected to play a pivotal, and possibly causal, role in their natural histories...

Neurodegenerative diseases are rarely caused by a mutation in a single gene but rather influenced by a combination of genetic, epigenetic and environmental factors. Emerging high-throughput technologies such as RNA sequencing have been instrumental in deciphering the molecular landscape of neurodegenerative diseases, however, the interpretation of such large amounts of data remains a challenge. Network biology has become a powerful platform to integrate multiple omics data to comprehensively explore the molecular networks in the context of health and disease...

Up-regulation of CB2R on activated microglial cells, the first step in neurodegeneration, has been widely demonstrated, and this finding makes the receptor a promising target in the early diagnosis and treatment of several neurodegenerative disorders such as Alzheimer's disease (AD), Parkinson's disease (PD), Huntington's disease (HD), and multiple sclerosis (MS). The development of CB2R PET ligands could help demonstrate the neurodegenerative pathogenesis, thus providing useful tools for characterizing the role of neuroinflammation in the progression of these disorders...

Neuroinflammation has been shown as an essential factor in the pathogenesis of neurodegenerative diseases, such as Alzheimer's disease (AD), Parkinson's disease (PD), Huntington's disease, and Multiple Sclerosis. Furthermore, activated microglia and increased pro-inflammatory cytokines are the major hallmarks in neurodegenerative diseases. A multimolecular complex named as inflammasome is involved in the process of inflammatory response, which can activate inflammatory caspases, leading to the cleavage and secretion of inflammatory cytokines, and finally generates a potent inflammatory response...

BACKGROUND: Various alterations of hypothalamic-pituitary-adrenal axis function have been described in patients with chronic renal failure. Nevertheless, controversial evidences were stated about the association between adrenal function deficiency (AD) and hemodialysis (HD). PURPOSE: The goal of this paper was to estimate indirect indices of the adrenal gland dysfunction which is potentially influenced by oxidative stress (OS) that still generates brain plasticity and reorganization of the functional control...

BACKGROUND: The cerebrospinal fluid (CSF) levels of total tau (t-tau) and Aβ1-42 are potential early diagnostic markers for probable Alzheimer's disease (AD). The influence of genetic variation on these CSF biomarkers has been investigated in candidate or genome-wide association studies (GWAS). However, the investigation of statistically modest associations in GWAS in the context of biological networks is still an under-explored topic in AD studies. The main objective of this study is to gain further biological insights via the integration of statistical gene associations in AD with physical protein interaction networks...

Potassium balance is a difficult task in hemodialysis: low potassium in the dialysate is associated with a high risk of sudden cardiac death, whereas excessive dialysate potassium may provoke insufficient removal and hyperkalemia. A better understanding of the problem can be achieved with the use of mathematical models of solute kinetics. This study is aimed at presenting an improved model of solute kinetics and fluid shifts during hemodialysis. It comprises a 2-compartment (intracellular and extracellular) description of sodium, potassium, and urea, including volume fluid shifts induced by osmotic forces...

There is increasing awareness on the role played by circadian rhythm abnormalities in neurodegenerative disorders such as Alzheimer's disease (AD) and Parkinson's disease (PD). The characterization of the circadian dysfunction parallels the mounting evidence that the hallmarks of neurodegeneration also affect the retina and frequently lead to loss of retinal ganglion cells (RGCs) and to different degrees of optic neuropathy. In the RGC population, there is the subgroup of cells intrinsically photosensitive and expressing the photopigment melanopsin [melanopsin-containing retinal ganglion cells (mRGCs)], which are now well known to drive the entrainment of circadian rhythms to the light-dark cycles...

Technique failure remains a frequent cause of peritoneal dialysis (PD) withdrawal. Many post-commencement predictors of PD technique failure have been identified, while predialysis predictors have remained unclear. The aim of this study was to identify predialysis indices for technique failure in PD patients. We recruited 206 consecutive PD patients who were treated at Nara Medical University Hospital between 1 April 1997 and 31 December 2012. Forty-eight patients were excluded because of transition from hemodialysis (HD) or withdrawal from PD within 3 months, leaving 158 patients for analysis...

BACKGROUND Hyperphosphatemia is a common problem in patients with kidney failure. It is usually mild and rarely severe enough to cause metabolic acidosis on its own. Besides kidney failure, use of phosphate containing enemas, rhabdomyolysis, and tumor lysis syndrome are common causes of severe hyperphosphatemia. CASE REPORT A 74-year-old man with a history of diabetes mellitus type II, arterial hypertension, and end stage renal disease, who was on hemodialysis and who had undergone hemicolectomy for ischemic bowel disease, and had not eaten for several days, developed severe metabolic acidosis, with an anion gap (AG) of 31 meq/L, -uncorrected for serum albumin...

In patients with insufficient blood pressure (BP) control, despite using a combination regimen containing an angiotensin receptor blocker and a calcium channel blocker (CCB), whether a greater dose of CCB or adding a diuretic is more effective at lowering BP remains unclear. We conducted a multicenter randomized clinical trial to compare the efficacy of switching from the daily administration of a single-pill fixed-dose combination of irbesartan (100 mg) and amlodipine (5 mg) to irbesartan (100 mg) with an increased dose of amlodipine (10 mg) (HD group, n=62) or irbesartan (100 mg) and amlodipine (5 mg) with 1 mg of indapamide (D group, n=63) in patients with poorly controlled hypertension...
