PURPOSE: Growth of intracranial fusiform aneurysms (IFA) may become clinically problematic through a mass effect or rupture. We investigated the growth rate and factors contributing to growth in asymptomatic untreated IFA. METHOD: As a retrospective review, we assessed patients diagnosed with asymptomatic IFA between August 2000 and September 2014, all untreated. No acute or symptomatic dissecting lesions were considered. Clinical and serial angiographic follow-up data were analyzed, defining growth as expansion > 2 mm in one or more dimensions...

BACKGROUND: During several anesthesiological procedures, needles are inserted through the skin of a patient to target nerves. In most cases, the needle traverses several tissues-skin, subcutaneous adipose tissue, muscles, nerves, and blood vessels-to reach the target nerve. A clear identification of the target nerve can improve the success of the nerve block and reduce the rate of complications. This may be accomplished with diffuse reflectance spectroscopy (DRS) which can provide a quantitative measure of the tissue composition...

PURPOSE: Anastomotic leak (AL) is a major complication of rectal cancer surgery. Despite advances in surgical practice, rates of AL have remained static at around 10-15%. The aetiology of AL is multifactorial, but one of the most crucial risk factors, which is mostly under the control of the surgeon, is blood supply to the anastomosis. The MRC/NIHR IntAct study will determine whether assessment of anastomotic perfusion using a fluorescent dye (Indocyanine Green) and near-infrared laparoscopy can minimise the rate of anastomotic leak as compared to conventional white light laparoscopy...

The intracellular cyclic diguanylate acid (c-di-GMP) has emerged as a prominent second signal molecule that coordinates sessile-motile transition and biofilm formation in many bacteria. Herein, we study the role of c-di-GMP in affecting microbial community shifts at different pH levels during simultaneous partial nitrification, anammox and denitrification process (SNAD) in integrated fixed film activated sludge (IFAS) reactor. The results demonstrated that the contents of c-di-GMP notably decreased in suspended sludge, whereas the contents of c-di-GMP in biofilm had no significant change as pH gradually increased from 7...

The tick-borne protozoan Babesia microti is responsible for more than 200 cases of transfusion-transmitted babesiosis (TTB) infection in the United States over the last 30 years. Measures to mitigate the risk of TTB include nucleic acid testing (NAT) and B. microti antibody testing. A fully automated prototype B. microti antibody test was developed on the ARCHITECT instrument. The specificity was determined to be 99.98% in volunteer blood donors (n=28,740) from areas considered as low endemic for B. microti The sensitivity of the prototype test was studied in experimentally-infected macaques; a total of 128 samples were detected compared to 125 with the indirect fluorescent antibody test (IFA), additionally, 83 (89...

M2 protein, a highly conserved protein of influenza A virus (IAV), plays an important role in virus particle uncoating, assembly, and budding. In the present study, eight monoclonal antibodies (mAbs) against the M2 protein of the H3N2 IAV strain were generated with recombinant truncated M2 protein or BSA-coupled M2 peptides as immunogens. The linear epitopes recognized by the mAbs were defined by IFA and peptide ELISA. The results showed that mAb 10F4 recognized an epitope located in the N-terminal 6-12 amino acids of the M2 peptide, and the mAbs 10D9, 1E2, 4B5, and 5G10 recognized the epitopes located in the C-terminal 62-77 amino acids of the M2 peptide...

Background: Differentiating scrub typhus from other acute febrile illness is difficult due to non specificity of clinical symptoms and relative absence of eschar in Indian population. The diagnosis thus relies mainly on laboratory tests. Antibody based serological tests are mainstay of scrub typhus diagnosis. Here, we evaluated the diagnostic performance of IgM ELISA, IgM IFA and ICT to detect antibodies against O. tsutsugamushi in acute serum of febrile patients. Methodology: The serum samples from 600 randomly selected patients suffering from acute undifferentiated fever were tested by all the three tests mentioned above...

BACKGROUND: Macro and micronutrients including iron and folic acid deficiencies are prevalent in Kenya, particularly during pregnancy resulting in anaemia. Despite efforts to control anaemia in pregnancy by adopting Iron and Folic Acid Supplementation (IFAS), this public health problem has persisted contributing to significant morbidity and mortality. The problem notwithstanding, there is poor IFAS compliance, whose reasons remain poorly understood, calling for their investigations. We sought to determine compliance status with IFAS and associated factors among pregnant women...

Scrub typhus (ST) is an underdiagnosed acute febrile illness in the Asia Pacific region with recent reemergence. Clinical diagnosis is difficult, and laboratory confirmation is largely based on serological and molecular tests. However, Weil-Felix test still remains the only test available in much of the rural tropics where a disproportionate number of cases occur. Sensitive and affordable assays are important for broader use and accurate diagnosis. We evaluated the diagnostic capabilities of serological and molecular assays on single acute clinical samples...

B cells in some fish were recently found to have potent phagocytic activities. Sea bass (Lateolabrax japonicus) as an important economical marine fish species, it could be used as an appropriate model to study the functions of B cells in phagocytosis. In the paper, three positive hybridomas designated as 1E11, 2H4 and 3F3 secreting monoclonal antibodies (MAbs) against sea bass immunoglobulin M (IgM) were produced and used as research tools. Indirect enzyme-linked immunosorbent assay showed that all the three MAbs had a high binding capacity with sea bass serum IgM...

In exploratory item factor analysis (IFA), researchers may use model fit statistics and commonly invoked fit thresholds to help determine the dimensionality of an assessment. However, these indices and thresholds may mislead as they were developed in a confirmatory framework for models with continuous, not categorical, indicators. The present study used Monte Carlo simulation methods to investigate the ability of popular model fit statistics (chi-square, root mean square error of approximation, the comparative fit index, and the Tucker-Lewis index) and their standard cutoff values to detect the optimal number of latent dimensions underlying sets of dichotomous items...
