Climate‐warming induced permafrost thaw exposes large amounts of carbon and nitrogen in soil at greater depths below the seasonally‐thawing active layer. The extent to which plant roots can reach and interact with these hitherto detached, deep carbon and nitrogen stores remains unknown. We aimed to quantify how permafrost thaw affects root dynamics across soil depths and plant functional types com

Based on all patients with tibial shaft fracture (n = 767) treated in the department of orthopedics in Malmö from 1955 to 1963, a retrospective cohort study was performed in 1990. Two hundred sixty-nine of the patients were still living in Malmö or had died in the city. Since all roentgenograms were available, all other fractures that this group of patients had sustained up to 1990 were included.

Noninvasive imaging methods are sought to objectively predict early response to therapy for high-grade glioma tumors. Quantitative metrics derived from diffusion-weighted imaging, such as apparent diffusion coefficient (ADC), have previously shown promise when used in combination with voxel-based analysis reflecting regional changes. The functional diffusion mapping (fDM) metric is hypothesized to

In patients with cutaneous openings, sinograph and fistulography are usually performed. Fistulae in the head/neck region and perineum are seldom life-threatening while enterocutaneous fistulae involving the small bowel can be a serious threat due to loss of fluid. Radiology contributes to the preoperative examination of these patients. Fistulography outlines communications to the gastrointestinal

Mixed phenotype acute leukemias (MPALs) represent a rare subgroup of acute leukemias with a poor prognosis. Proper diagnosis and classification of MPAL is extremely important for patients' outcome. Morphology and flow cytometry recognize two types of MPAL: the “bilineal” MPAL with the coexistence of two blast populations of different lineage and truly “biphenotypic” MPAL coexpressing markers of mo

The ETV6/FLT3 fusion gene has been recently reported in association with myeloproliferative neoplasm with eosinophilia (MPN-Eo) and peripheral T cell lymphoma. Favorable clinical response to a targeted FLT3 tyrosine kinase inhibitor (FLT3 TKI) was noted. Here we report a novel phenotype associated with ETV6/FLT3 rearrangement, in a 38-year-old female with presentation of progressive lymphadenopath

This prospective phase II study evaluated the efficacy of azacitidine (Aza) + erythropoietin (Epo) in transfusion-dependent patients with lower-risk myelodysplastic syndrome (MDS). Patients ineligible for or refractory to full-dose Epo + granulocyte colony stimulation factors for 48 weeks and a transfusion need of ≥ 4 units over 8 weeks were included. Aza 75mgm -2 d-1, 5/28 days, was given for six

Del(5q) myelodysplastic syndromes defined by the International Prognostic Scoring System as low- or intermediate- 1-risk (lower-risk) are considered to have an indolent course; however, recent data have identified a subgroup of these patients with more aggressive disease and poorer outcomes. Using deep sequencing technology, we previously demonstrated that 18% of patients with lower-risk del(5q) m

Diffuse large B-cell lymphoma (DLBCL) is a heterogeneous disease, and infectious agents are suspected to be involved in the tumorigenesis of DLBCL. MicroRNAs (miRNAs) are non-coding RNAs modulating protein expression. We compared miRNA expression profiles in lymph node tissues of patients with DLBCL of the activated B-cell like (ABC) type from two geographical areas with different background expos

We examined the capacity of budgerigars (Melopsittacus undulatus)to visually detect dark single targets against a brighter background and established their spatial resolution limit for such targets. While the sampling density of the retina limits the resolution of gratings, target detection is theoretically limited by contrast sensitivity. This allows many animals to detect single targets smaller

Alpha1-microglobulin (alpha1m) is an electrophoretically heterogeneous plasma protein. It belongs to the lipocalin superfamily, a group of proteins with a three-dimensional (3D) structure that forms an internal hydrophobic ligand-binding pocket. Alpha1m carries a covalently linked unidentified chromophore that gives the protein a characteristic brown color and extremely heterogeneous optical prope

cDNA coding for alpha 1-microglobulin, an immunoregulatory plasmaprotein, was isolated from bovine liver. The sequence of a total of 1258 nucleotides revealed an open reading frame of 352 amino acids. This included alpha 1-microglobulin, 182 amino acids, and bikunin, the light chain of the plasmaprotein inter-alpha-inhibitor, 147 amino acids. The two proteins were connected by a basic tetrapeptide

Most group A streptococcal strains bind immunoglobulins (Ig) and fibrinogen to their cell walls. It is shown in this paper that the Ig-binding of three different strains was much weaker at 37 degrees C than at room temperature (20 degrees C), whereas the fibrinogen binding was unaffected by temperature. The binding properties and molecular sizes of two purified group A streptococcal cell surface p

alpha 1-Microglobulin is an immunosuppressive plasma protein synthesized by the liver. The isolated protein is yellow-brown, but the hypothetical chromophore has not yet been identified. In this work, it is shown that a human liver cell line, HepG2, grown in a completely synthetic and serum-free medium, secretes alpha 1-microglobulin which is also yellow-brown, suggesting a de novo synthesis of th

The precursor protein alpha 1-microglobulin-bikunin was cleaved to the same degree whether expressed in CHO cells or in mutated CHO cells, RPE.40 cells, suggested to lack a functional form of the intracellular protease furin. Thus, alpha 1-microglobulin-bikunin probably is not cleaved in vivo by furin. However, simultaneous overexpression of the precursor and furin in COS, CHO and RPE.40 cells inc

Two nitrifying MBBR reactors were operated in parallel, one with PAC dosing and one without, to determine the effects of PAC dosing on nitrification and micropollutant adsorption in municipal wastewater. The removal of micropollutants was evaluated for several doses of PAC and batch experiments were performed to measure adsorption kinetics and nitrification rates. The influence of PAC on the nitri

Introduction: The Visual Ergonomics Risk Assessment Method (VERAM) is a newly developed and validated method to assess visual ergonomics at workplaces. VERAM consists of a questionnaire and an objective evaluation. Objective: To evaluate reliability of VERAM by assessing test-retest reliability of the questionnaire, and intra- and inter-rater reliability of the objective evaluation. Methods: Forty
