Insights on the structural perturbations in human MTHFR Ala222Val mutant by protein modeling and molecular dynamics

Methylenetetrahydrofolate reductase (MTHFR) protein catalyzes the only biochemical reaction which produces methyltetrahydrofolate, the active form of folic acid essential for several molecular functions. The Ala222Val polymorphism of human MTHFR encodes a thermolabile protein associated with increased risk of neural tube defects and cardiovascular disease. Experimental studies have shown that the

Magnetic resonance imaging, scintigraphy, and arthroscopic evaluation of traumatic hemarthrosis of the knee

Forty patients with traumatic knee hemarthrosis were examined within 1 week after injury and observations made with magnetic resonance imaging, scintigraphy, arthroscopic evaluation, radiography, and physical examination were compared. Thirty-four patients (85%) had anterior cruciate ligament injuries according to the arthroscopic findings and 28 (83%) of these had associated meniscal tears. Magne

Mobility particle size spectrometers: harmonization of technical standards and data structure to facilitate high quality long-term observations of atmospheric particle number size distributions

Mobility particle size spectrometers often referred to as DMPS (Differential Mobility Particle Sizers) or SMPS (Scanning Mobility Particle Sizers) have found a wide range of applications in atmospheric aerosol research. However, comparability of measurements conducted world-wide is hampered by lack of generally accepted technical standards and guidelines with respect to the instrumental set-up, me

Posterior Insular Molecular Changes in Myofascial Pain

Temporomandibular disorders (TMD) include craniocervical pain conditions with unclear etiologies. Central changes are suspected; however, few neuroimaging studies of TMD exist. Single-voxel proton magnetic resonance spectroscopy (H-1-MRS) was used before and after pressure-pain testing to assess glutamate (Glu), glutamine (Gln), N-acetylaspartate (NAA), and choline (Cho) levels in the right and le

Intratumoral COX-2 inhibition enhances GM-CSF immunotherapy against established mouse GL261 brain tumors.

Immunotherapy has shown effectiveness against experimental malignant brain tumors, but the clinical results have been less convincing most likely due to immunosuppression. Prostaglandin E2 (PGE2 ) is the key immunosuppressive product of cyclooxygenase-2 (COX-2) and increased levels of PGE2 and COX-2 have been shown in several tumor types including brain tumors. In the current study, we report enha

Identification and characterization of a novel cartilage gene product CILP, which is an early indicator of osteoarthritis.

The aim of this work was to study alterations in the matrix composition of human articular cartilage in different stages of osteoarthritis and to isolate and characterize one of the proteins that is altered in the osteoarthritic process. The metabolism of articular cartilage in different stages of osteoarthritis including early asymptomatic OA was monitored in a culture system of metabolically lab

Christian Masculinity : Men and Religion in Northern Europe in the 19th and 20th Centuries

Christianity has markedly patriarchal traits, and by tradition men have played the dominant role in the affairs of all churches. Men ran the churches, and the clergy long remained exclusively male, but at the parochial level women began to dominate more and more. In middle-class, liberal, anti-clerical, and socialist circles, the exercise of religion became identified as a female concern. But was

Could the increased use of e-bikes (pedelecs) in Sweden contribute to a more sustainable transport system?

The transport sector accounts for large proportions of greenhouse gas emissions and energy usage in Sweden, about 40% and 30%, respectively. Most of this, 93%, comes from road transports. There is, therefore, a strong political desire to reduce the use of fossil fuels in road transport. Several alternatives to fossil fuels have been discussed and, more recently, interest in electrically driven veh

Cold intolerance and neuropathic pain after peripheral nerve injury in upper extremity

Cold intolerance and pain can be a substantial problem in patients with peripheral nerve injury. We aimed at investigating the relationships among sensory recovery, cold intolerance, and neuropathic pain in patients affected by upper limb peripheral nerve injury (Sunderland type V) treated with microsurgical repair, followed by early sensory re-education. In a cross-sectional clinical study, 100 p

Primary treatment and relative survival by stage and age in vulvar squamous cell carcinoma : A population-based SweGCG study

Objective: Vulvar cancer affects mainly elderly women and with an ageing population the incidence has increased. We explored the primary treatment patterns and relative survival of patients with vulvar squamous cell carcinoma (VSCC) by stage and age-group. Methods: A population-based nationwide study on women diagnosed with VSCC between 2012 and 2016 and registered in the Swedish Quality Registry

Combined vitamin D, ibuprofen and glutamic acid decarboxylase-alum treatment in recent onset Type i diabetes : Lessons from the DIABGAD randomized pilot trial

Aim: Double-blind placebo-controlled intervention using glutamic acid decarboxylase (GAD)-alum, vitamin D and Ibuprofen in recent onset Type I diabetes (T1D). Methods: 64 patients (T1D since <4 months, age 10-17.99, fasting sC-peptide ≥0.12 nmol/l, GADA-positive) were randomized into Day(D) 1-90 400 mg/day Ibuprofen, D1-450 vitamin D 2000 IU/day, D15, 45 sc. 20 μg GAD-alum; as A but placebo instea

Nailfold capillaroscopy in systemic sclerosis: Data from the EULAR scleroderma trials and research (EUSTAR) database

Objective: The aims of this study were to obtain cross-sectional data on capillaroscopy in an international multi-center cohort of Systemic Sclerosis (SSc) and to investigate the frequency of the capillaroscopic patterns and their disease-phenotype associations. Methods: Data collected between June 2004 and October 2011 in the EULAR Scleroderma Trials and Research (EUSTAR) registry were examined.

Characterization of the NIST Seaweed Standard Reference Material

The National Institute of Standards and Technology (NIST) Standard Reference Material (SRM) for seaweed was developed through an interlaboratory comparison with 24 participants from 16 countries. After evaluating different techniques to calculate certified values for the radionuclides, the median method was found to be the most representative technique. The certified values were provided for 13 ra

Block-copolymer micro-emulsion with solvent-induced segregation

Reverse micelle formation of the poly(ethylene oxide)/poly(propylene oxide) block-copolymer (EO)(13)(PO)(30)(EO)(13) (L64) in p-xylene was investigated as a function of water content and copolymer content, using small-angle neutron scattering (SANS). PEO/PPO block-copolymers are generally soluble in xylene but without forming aggregates. However, the effective block segregation increases dramatica

Risk of plasma cell and lymphoproliferative disorders among 14 621 first-degree relatives of 4458 patients with monoclonal gammopathy of undetermined significance in Sweden

Familial clustering of the precursor condition, monoclonal gammopathy of undetermined significance (MGUS) has been observed in case reports and in smaller studies. Using population-based data from Sweden, we identified 4458 MGUS patients, 17 505 population-based controls, and first-degree relatives of patients (n = 14 621) and controls (n = 58 387) with the aim to assess risk of MGUS and lymphopro

Modulation of [(35)S]GTPgammaS binding to chinese hamster ovary cell membranes by D(2(short)) dopamine receptors

Rat dopamine D(2short) expressed in Chinese hamster ovary (CHO) cells were characterized by means of activation of [(35)S]-guanosine 5'-O-(gamma-thiotriphosphate) ([(35)S]GTPgammaS) binding and inhibition of [(3)H]raclopride binding. Among 18 dopaminergic ligands studied dopamine, NPA, apomorphine and quinpirole were full agonists in activation of [(35)S]GTPgammaS binding, while seven ligands were
