The knowledge of the taxonomy and classification of algae (including lichenized) has recently increased rapidly, but there are still many gaps. We aimed to 1) identify the Fuscidea photobionts by locating their taxonomic positions in the green algal classification, and 2) to resolve their interspecific relationships. The lichenized algae were examined based on morphological observations of axenic isolates as well as molecular studies of 18S and ITS nrDNA sequences. Analysis of the secondary structure of the ITS2 operon complemented these investigations...

Although patients with indolent B-cell lymphomas have a relatively good survival rate, conventional chemotherapy is not curative. Disease courses are typically characterized by multiple relapses and progressively shorter response duration with subsequent lines of therapy. There has been an explosion of innovative targeted agents in the past years. This review discusses current knowledge on the etiology of indolent B-cell lymphomas with respect to the role of micro-organisms, auto-immune diseases, and deregulated pathways caused by mutations...

Neurological injuries can be divided into those with traumatic and nontraumatic causes. The largest groups are traumatic brain injury (TBI) and nontraumatic stroke. TBI patients may present with intracranial hemorrhages (contusions, or subdural or epidural hematomas). Strokes are ischemic or hemorrhagic. In all these disorders, thrombosis and hemostasis play a major role. Treatment aims to either cease bleeding and/or restore perfusion. We reviewed hemostatic and thrombolytic therapies in patients with neurological injuries by MEDLINE and EMBASE search using various key words for neurological disorders and hemostatic therapies restricted to English language and human adults...

BACKGROUND: The role of temozolomide chemotherapy in newly diagnosed 1p/19q non-co-deleted anaplastic gliomas, which are associated with lower sensitivity to chemotherapy and worse prognosis than 1p/19q co-deleted tumours, is unclear. We assessed the use of radiotherapy with concurrent and adjuvant temozolomide in adults with non-co-deleted anaplastic gliomas. METHODS: This was a phase 3, randomised, open-label study with a 2 × 2 factorial design. Eligible patients were aged 18 years or older and had newly diagnosed non-co-deleted anaplastic glioma with WHO performance status scores of 0-2...

Cationic ionic liquids-based surfactants (ILS), such as 4-methyl pyridinium bromide (CnPBr, where n=4,6,8), were used in preparation of polyacrylamide gels, sample buffer, and running buffer for cationic ILS polyacrylamide gel electrophoresis (ILS-PAGE). These ILS are liquids in the pure state and were selected for improved separation of ribonuclease b (Rib b) glycoforms in a single step and a protein mixture containing bovine serum albumin (BSA, pI-4.8, 66.5kDa), ovalbumin (Ova, pI-4.6, 44.3kDa), α-chymotrypsinogen (α-Chy, pI-8...

Luminex single antigen bead (SAB) assay utilizes beadsets coated with a set of cloned and purified HLA molecules, for monitoring serum anti-HLA antibodies. Particularly, the level of serum IgG against native HLA-I trimers (heavy chain (HC) and β2-microglobulin (β2m) with a peptide), expressed in allograft tissues is correlated with graft failure. In addition to native trimeric HLAI, the beadsets may carry HC only or the dimeric variants, peptide-free HC with β2m and β2m-free HC with or without peptides...

Ex vivo gene therapy using lentiviral vectors (LVs) is a proven approach to treat and potentially cure many hematologic disorders and malignancies but remains stymied by cumbersome, cost-prohibitive, and scale-limited production processes that cannot meet the demands of current clinical protocols for widespread clinical utilization. However, limitations in LV manufacture coupled with inefficient transduction protocols requiring significant excess amounts of vector currently limit widespread implementation...

OBJECTIVES: Diabetes mellitus (DM) is a common complication of chronic pancreatitis (CP). Past studies for DM risk factors in CP have been limited to single centers or highly focused on a single etiology such as alcoholic or hereditary disease. We studied risk factors for DM in a large population of patients with CP of all etiologies enrolled in the North American Pancreatitis 2 studies. METHODS: Participants (1,171) with CP (n=383 with DM, n=788 without DM) were enrolled prospectively from 26 participating centers...

Oral cholera vaccination was used as part of cholera control in Haiti, but the vaccine does not provide complete protection. We conducted secondary data analyses of a vaccine effectiveness study in Haiti to evaluate risk factors for cholera among cholera vaccine recipients. Individuals vaccinated against cholera that presented with acute watery diarrhea and had a stool sample positive for Vibrio cholerae O1 were included as cases. Up to four vaccinated individuals who did not present for treatment of diarrhea were included as controls for each case, and matched by location of residence, enrollment time, and age...

BACKGROUND: Little cigar and cigarillo use is becoming more prevalent in the United States and elsewhere, with implications for public health. As little cigar and cigarillo use grows in popularity, big social media data (eg, Instagram, Google Web Search, Twitter) can be used to capture and document the context in which individuals use, and are marketed, these tobacco products. Big social media data may allow people to organically demonstrate how and why they use little cigars and cigarillos, unprimed by a researcher, without instrument bias and at low costs...

We investigated the strength of commonly used spinal needles in relation to the amount of deformation, and registered forces during standardised testing. We investigated differences between manufacturers for the same length and gauge of Luer and non-Luer needles, and examined the effect of the internal stylet in terms of needle strength. A specialised rig was designed to perform the testing in both the horizontal and axial plane, reflecting common industrial tests and clinical use. Needles from four commonly used manufacturers were used (Vygon, Becton Dickinson, B Braun, and Pajunk)...

The rape stem weevil, Ceutorhynchus napi Gyll., is a serious pest of winter oilseed rape (Brassica napus L.) crops in Europe causing severe yield loss. In currently used oilseed rape cultivars no resistance to C. napi has been identified. Resynthesized lines of B. napus have potential to broaden the genetic variability and may improve resistance to insect pests. In this study, the susceptibility to C. napi of three cultivars, one breeding line and five resynthesized lines of oilseed rape was compared in a semi-field plot experiment under multi-choice conditions...

The variety of beers available for consumption has increased due to the recent emergence of many craft brewing operations and it has been suggested that this is affecting how consumers evaluate beer. Currently, beer consumers are mostly male and only 20% of women are primarily beer drinkers. The main objective of this project is to compare and contrast descriptions of beer products created by males and females. The preferred attribute elicitation (PAE) method was used to create a description of 4 beers common to residents of Nova Scotia, Canada...
