Methylation levels assessment with Methylation-Sensitive High-Resolution Melting (MS-HRM).

Testing for disease-related DNA methylation changes provides clinically relevant information in personalized patient care. Methylation-Sensitive High-Resolution Melting (MS-HRM) is a method used for measuring methylation changes and has already been used in diagnostic settings. This method utilizes one set of primers that initiate the amplification of both methylated and non-methylated templates.

Association of Birth Weight With Type 2 Diabetes and Glycemic Traits: A Mendelian Randomization Study.

Importance: Observational studies have shown associations of birth weight with type 2 diabetes (T2D) and glycemic traits, but it remains unclear whether these associations represent causal associations.

Objective: To test the association of birth weight with T2D and glycemic traits using a mendelian randomization analysis.

Design, Setting, And Participants: This mendelian randomization study used a genetic risk score for birth weight that was constructed with 7 genome-wide significant single-nucleotide polymorphisms.

Overexpression of cyclooxygenase-2 in adipocytes reduces fat accumulation in inguinal white adipose tissue and hepatic steatosis in high-fat fed mice.

Cyclooxygenases are known as important regulators of metabolism and immune processes via conversion of C20 fatty acids into various regulatory lipid mediators, and cyclooxygenase activity has been implicated in browning of white adipose tissues. We generated transgenic (TG) C57BL/6 mice expressing the Ptgs2 gene encoding cyclooxygenase-2 (COX-2) in mature adipocytes. TG mice fed a high-fat diet displayed marginally lower weight gain with less hepatic steatosis and a slight improvement in insulin sensitivity, but no difference in glucose tolerance.

Synovial incorporation of polyacrylamide hydrogel after injection into normal and osteoarthritic animal joints.

Objective: Polyacrylamide hydrogel (PAAG) is a non-toxic, non-degradable synthetic product, used for years in the augmentation of soft tissues. Preliminary results in animals and humans have suggested long-lasting beneficial effects on symptoms of osteoarthritis (OA). The aim of this histopathological study was to investigate whether intra-articular injection of PAAG is integrated into synovial tissue in normal and OA animal joints, and if this integration is sustained.

Occurrence of diarrhoea and intestinal pathogens in non-medicated nursery pigs.

Background: Intestinal disease in nursery pigs is the most common cause of antibiotic usage in pigs in Denmark. The decision to initiate batch medication of intestinal diseases in nursery pigs is typically made by the stock personnel based on clinical assessments of pigs and counting of diarrhoeic faecal pools on the pen floor. The target population of this study was batches of nursery pigs (10-66 days after weaning) where the stock personnel assessed the pigs to be without signs of intestinal disease and therefore did not needed treatment.

Effects of carvedilol and propranolol on circulatory regulation and oxygenation in cirrhosis: a randomised study.

Background And Aims: Newer studies suggest that carvedilol, a beta-blocker with a moderate anti-alpha-1 activity, is superior to propranolol in reducing the portal pressure and risk of variceal bleeding. The effect on arterial blood pressure is a matter of concern especially in decompensated patients.

Aims: to assess potential differential effects of beta-blockers and beta-blockers with moderate anti-alpha-1 activity on selected haemodynamic, humoral, and respiratory characteristics in cirrhosis.

Regional cerebral blood flow and glucose metabolism during propofol anaesthesia in healthy subjects studied with positron emission tomography.

Background: General anaesthetics can alter the relationship between regional cerebral glucose metabolism rate (rGMR) and regional cerebral blood flow (rCBF). With the present study, we wanted to assess quantitatively the effects of propofol on rCBF and rGMR in the same healthy volunteers measured with positron emission tomography (PET).

Methods: (15)O-labelled water and (18)F fluorodeoxyglucose were used as PET tracers to determine rCBF and rGMR, respectively, in eight healthy volunteers during the waking state (baseline) and during propofol anaesthesia.

UCP1 induction during recruitment of brown adipocytes in white adipose tissue is dependent on cyclooxygenase activity.

Background: The uncoupling protein 1 (UCP1) is a hallmark of brown adipocytes and pivotal for cold- and diet-induced thermogenesis.

Methodology/principal Findings: Here we report that cyclooxygenase (COX) activity and prostaglandin E(2) (PGE(2)) are crucially involved in induction of UCP1 expression in inguinal white adipocytes, but not in classic interscapular brown adipocytes. Cold-induced expression of UCP1 in inguinal white adipocytes was repressed in COX2 knockout (KO) mice and by administration of the COX inhibitor indomethacin in wild-type mice.

LMNA rs4641 and the muscle lamin A and C isoforms in twins--metabolic implications and transcriptional regulation.

Context: Lamins are essential for nuclear shape and function. Polymorphisms in LMNA may associate with fat and muscle development and aging.

Objective: Our aim was to determine the influence of LMNA rs4641 on lean body mass (LBM) and fat mass (FM), in vivo metabolism, and expression of LMNA transcripts in human skeletal muscle.

Regional cerebral glucose metabolism during sevoflurane anaesthesia in healthy subjects studied with positron emission tomography.

Background: The precise mechanism by which sevoflurane exerts its effects in the human brain remains unknown. In the present study, we quantified the effects of sevoflurane on regional cerebral glucose metabolism (rGMR) in the human brain measured with positron emission tomography.

Methods: Eight volunteers underwent two dynamic 18F-fluorodeoxyglucose positron emission tomography (PET) scans.

Assessment of hypoxia in experimental mice tumours by [18F]fluoromisonidazole PET and pO2 electrode measurements. Influence of tumour volume and carbogen breathing.

The aim of this study was to compare a non-invasive 18F-fluoromisonidazole ([18F]FMISO) PET assessment of tumour hypoxia with invasive Eppendorf pO2 measurements in 150-1,500 mm3 C3H mammary carcinomas transplanted on the back of CDF1 mice. The tumour-bearing mice breathed either carbogen gas (95% oxygen, 5% CO2) or normal air during both examinations. Additional autoradiography was performed in separate tumours treated similarly.

Anti-c-myc antibody 9E10: epitope key positions and variability characterized using peptide spot synthesis on cellulose.

The 9E10 antibody epitope (EQKLISEEDL) derives from a protein sequence in the human proto-oncogen p62(c-myc) and is widely used as a protein fusion tag. This myc-tag is a powerful tool in protein localization, immunochemistry, ELISA or protein purification. Here, we characterize the myc-tag epitope by substitutional analysis and length variation using peptide spot synthesis on cellulose.

Long-term renoprotective effect of nisoldipine and lisinopril in type 1 diabetic patients with diabetic nephropathy.

Objective: To compare the long-term effect on kidney function of a long-acting calcium antagonist (nisoldipine) versus a long-acting ACE inhibitor (lisinopril) in hypertensive type 1 diabetic patients with diabetic nephropathy.

Research Design And Methods: We performed a 4-year prospective, randomized, double-dummy controlled study comparing nisoldipine (20-40 mg once a day) with lisinopril (10-20 mg once a day). The study was double-blinded for the first year and single-blinded thereafter.

Feasibility of detecting hypoxia in experimental mouse tumours with 18F-fluorinated tracers and positron emission tomography--a study evaluating [18F]Fluoro-2-deoxy-D-glucose.

The study was designed to investigate the binding of [18F]Fluoromisonidazole ([18F]FMISO) and [18F]Fluoro-2-deoxy-D-glucose ([18F]FDG) in a C3H mouse mammary carcinoma. Non-anaesthetized tumour-bearing animals breathing either normal air or carbogen (to reduce tumour hypoxia) were examined by PET after tracer injection. Tumours were identified by radioactive labelling and methods of defining regions of interest (ROI) in the tumours were investigated.
