In both the Sun and the early universe, the He(α,γ)Be reaction plays a key role. The rate of this reaction is the least certain nuclear input needed to calculate both the primordial Li abundance in big bang nucleosynthesis (BBN) and the solar neutrino flux. Taking advantage of several recent highly precise experiments, we analyse modern He(α,γ)Be data using a robust and minimally model dependen...

Although the role of α-synuclein aggregation on Parkinson's disease is relatively well known, the physiological role and the regulatory mechanism governing the expression of α-synuclein are unclear yet. We recently reported that α-synuclein is expressed and secreted from cultured astrocytes. In this study, we investigated the effect of valproic acid (VPA), which has been suggested to provide ne...

Objective Background: Failure in the endometrial receptivity may account for a significant number of infertility cases including unexplained infertility in women. Reduction in the endometrial estrogen receptor-alpha (ER-α) expression during window of implantation may be a critical event that coincides with expression of specific genes and providing a receptive endometrium. The aim of present st...

Outlier identification often implies inspecting each z-transformed variable and adding a Mahalanobis D2. Multiple outliers may mask each other by increasing variance estimates. Caroni & Prescott (1992) proposed a multivariate extension of Rosner’s (1983) technique to circumvent masking, taking sample size into account to keep the false alarm risk below, say, α = .05. Simulations studies here co...

introduction: the systemic and local content of inflammatory cytokines and chemokines play substantial roles in pathophysiology of arthritis. this study was purposed to verify the roles of synovial tnf-α, il-6 and fractalkine (fkn) in edema changes during different stages of complete freund’s adjuvant (cfa)-induced knee arthritis in rats. methods: 168 male wistar rats were divided in 7 groups a...

We consider the equation Au = f, f ∈ R(A), where A ∈ L(H,F ) and H, F are real Hilbert spaces. We suppose that instead of f we have an approximation f̃ ∈ F and inexact noise level δ. We consider the case where δ may be a serious overestimation with ‖f̃−f‖ ≤ δ, but also the case of possible underestimation of the noise level: for example, it may be known only that with high probability δ/‖y − y∗‖ ...

We view match as an operator that takes two graph-like structures (e.g., XML schemas) and produces a mapping between the nodes of these graphs that correspond semantically to each other. Semantic schema matching is based on the two ideas: (i) we discover mappings by computing semantic relations (e.g., equivalence, more general); (ii) we determine semantic relations by analyzing the meaning (con...

OBJECTIVE This study aimed to determine the express level of tumour necrosis factor α (TNF-α) in the decidual tissue and peripheral blood of patients with recurrent spontaneous abortion (RSA). MATERIAL AND METHODS Eighty RSA patients and 100 control women were recruited in this study. Enzyme-linked immunosorbent assay (ELISA) was applied to determine the expression level of TNF-α in periphera...

Background: Periodontitis and rheumatoid arthritis (RA) share a number of clinical and pathologic features, one of which is the presence of the tumor necrosis factor alpha (TNF-α)-induced bone resorption that is involved in the pathogenesis of both. Objectives: To investigate the effect of TNF-α blockade on periodontal conditions in patients with active RA. Method: The periodontal statuses of 3...
