Objective: To explore the expression of Tau protein in breast invasive ductal carcinomas and examine the correlation between its expression and clinicopathological characteristics of breast cancer.
Methods: The clinicopathological data of 150 breast cancer patients at Third Municipal Hospital from October 2007 to June 2011 were collected and analyzed. Immunohistochemical method was used to detect the expressions of estrogen receptor (ER), progesterone receptor (PR), HER-2 and Tau protein.
Results: No correlations existed between the expression of Tau protein and age, tumor size or node metastasis of breast cancer patients (χ(2) = 0.02, P = 0.88; χ(2) = 0.55, P = 0.46; χ(2) = 1.02, P = 0.31). The expressions of Tau in ER positive patients were significantly higher than ER negative patients. And this trend extended to PR positive and HER-2 negative patients (χ(2) = 15.77, P = 0.00; χ(2) = 5.03, P = 0.03; χ(2) = 8.00, P = 0.01). The expression of Tau protein in Luminal A subtype was significantly higher than in Luminal B subtype, HER-2 over-expression subtype and basal like subtype (χ(2) = 7.26, P = 0.01).
Conclusions: Over-expressed in breast cancer, Tau protein is associated with ER, PR and HER-2. However, the relation between Tau protein and prognosis of breast cancer requires further researches.

Insulin resistance is a condition characterized by the attenuated biological response in the presence of normal or elevated insulin level and therefore is characterized by the impaired sensitivity to insulin and impaired glucose disposal and utilization. Insulin resistance in brain/Brain insulin resistance (BIR) is accompanied by the various manifestations including alteration in glucose sensing by hypothalamic neurons, impaired sympathetic outflow in response to hypoglycemia, increased ROS production, impaired mitochondrial oxygen consumption in the brain, cognitive deficits and neuronal cell damage. It has been reported that the disrupted insulin signaling is accompanied by the reduced expression of insulin receptor (IR)/insulin receptor substrate 1 (IRS1)/PI3K/AKT and IGF-1 receptor (IGF-1R)/IRS2/PI3K pathways.

Plasma biomarkers have great potential in the screening, diagnosis, and monitoring of Alzheimer's disease (AD). However, findings on their associations with cerebral perfusion and structural changes are inconclusive. We examined both cross-sectional and longitudinal associations between plasma biomarkers and cerebral blood flow (CBF), gray matter (GM) volume, and white matter (WM) integrity.

Objective: Fixed dose combination (FDC) dolutegravir (DTG) plus rilpivirine (RPV) is an approved antiretroviral treatment regimen for people with HIV. The steady-state pharmacokinetics (PK) of FDC DTG+RPV in hemodialysis (HD) has not been previously studied.
Design: We performed a single-center, prospective evaluation of the steady-state PK of FDC DTG +RPV in 4 adults without HIV either requiring HD and in 4 matched participants with normal renal function.

Amyloidosis is a group of proteinopathies characterized by the systemic or organ-specific deposition of proteins in the form of amyloid fibers. Nearly 40 proteins play a role in these pathologies, and the structures of the associated fibers are beginning to be determined by Cryo-EM. However, the molecular events underlying the process, such as fiber nucleation and elongation, are poorly understood, which impairs developing efficient therapies.

The MAPT gene encodes Tau protein, a member of the large family of microtubule-associated proteins. Tau forms large insoluble aggregates that are toxic to neurons in several neurological disorders, and neurofibrillary Tau tangles represent a key pathological hallmark of Alzheimer's disease (AD) and other tauopathies. Lowering Tau expression levels constitutes a potential treatment for AD but the mechanisms that regulate Tau expression at the transcriptional or translational level are not well understood.
