Abstract Background: Mannose-binding lectin (MBL) is a constituent of the human innate immune system which may play an important role in combating a variety of infectious diseases and thus may be important for determining hepatitis B virus (HBV) persistence. In this study, we determined MBL genotypes in chronic hepatitis B subjects, spontaneously recovered subjects and healthy controls. Me...
Dolph-Chebychev arrays are known to exhibit the best compromise between sidelobe level and directivity. However, they place a constraint on the null locations. Any attempt to impose nulls or get them deeper will impact the directivity/sidelobe level trade-off. In this work, null placement in Dolph-Chebychev arrays through element position perturbation is carried out based on Taguchi method whil...
The present study investigates how adult native speakers of two null subject Romance languages, European Portuguese (EP) and Italian, interpret overt pronominal subjects in intrasentential contexts. Participants were 30 EP Italian. Each language group was administered multiple-choice tasks (speeded untimed), which crossed the following variables: ‘animacy matrix object’ ([+ human] vs. [- human]...
Background & Aims: Recurrent Pregnancy Loss (RPL) is defined as two or more consecutive spontaneous abortions. Glutathione S-transferase genes produce isoenzymes that protect embryo against oxidative stress. The aim of this study was to determine the removal of the two genes, GSTT1 and GSTM1 in male partners of couples having RPL. Materials & Methods: A case-control study of 102 cases w...
the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...
In recent years, experimental and theoretical research on the nature of supermassive bodies that inhabit central regions galaxies has grown significantly. this contribution, we study motion unitary mass test particles in a perturbed Kerr-like metric. The metric represents approximate exterior spacetime massive rotating body with quadrupole moment $q$. Through extensive geodesics, it is found ch...
A commonly used test for natural selection has been to compare population differentiation for neutral molecular loci estimated by F(ST) and for the additive genetic component of quantitative traits estimated by Q(ST). Past analytical and empirical studies have led to the conclusion that when averaged over replicate evolutionary histories, Q(ST) = F(ST) under neutrality. We used analytical and s...
having conducted the experiment and analysed the data, the researcher computed the groups mean scores and variances for the test relating to the research question. as the final atep, a t-test was conodonted for the hypothesis. as noted earlier, the significance level was determined at .05 and .01 respectively. the observed t-value was higher than the critical t-value at. 5 and .01 levels. conse...
Ubiquinone (coenzyme Q, or Q) is a membrane constituent, whose head group is capable of accepting and donating electrons and whose lipidic side chain is composed of a variable number of isoprene subunits. A possible role for Q as a dietary antioxidant for treating conditions that involve altered cellular redox states is being intensely studied. Mutations in the clk-1 gene of the nematode Caenor...
BACKGROUND The aim of this study was to determine the relationship between body position, pulmonary function (PF) and bronchial blood flow (Q(aw)) in a group of heart failure (HF) and control subjects. METHODS Thirty-six subjects were studied: 24 stable, ambulatory HF patients (HF: LVEF=27±6%, age=65±9 yr) and 12 age- and sex-matched controls (CTRL: LVEF=60±7%, age=62±8 yr). Measures of Q˙(aw...
