Follicular adenoma in ectopic thyroid. A case-report
2017
Highlights • Ectopic thyroid is thyroidal tissue located far from its anatomic place. • A patient under our observation displayed left submandibular swelling. • The FNAC test report described a follicular adenoma. • Based on the FNAC diagnosis, we surgically removed the mass. • The post-operative follow-up was uneventful.
Residential greenness-related DNA methylation changes
2021
Abstract Background Residential greenness has been associated with health benefits, but its biological mechanism is largely unknown. Investigation of greenness-related DNA methylation profiles can contribute to mechanistic understanding of the health benefits of residential greenness. Objective To identify DNA methylation profiles associated with greenness in the immediate surroundings of the residence. Methods We analyzed genome-wide DNA methylation in 1938 blood samples (982 participants) from the Swiss Cohort Study on Air Pollution and Lung and Heart Diseases in Adults (SAPALDIA). We estimated residential greenness based on normalized difference vegetation index at 30 × 30 m cell (green3…
The role ofSphagnummosses in the methane cycling of a boreal mire
2010
Peatlands are a major natural source of atmospheric methane (CH4). Emissions from Sphagnum-dominated mires are lower than those measured from other mire types. This observation may partly be due to methanotrophic (i.e., methane-consuming) bacteria associated with Sphagnum. Twenty-three of the 41 Sphagnum species in Finland can be found in the peatland at Lakkasuo. To better understand the Sphagnum-methanotroph system, we tested the following hypotheses: (1) all these Sphagnum species support methanotrophic bacteria; (2) water level is the key environmental determinant for differences in methanotrophy across habitats; (3) under dry conditions, Sphagnum species will not host methanotrophic ba…
Heterogeneity of carbon loss and its temperature sensitivity in East-European subarctic tundra soils
2016
Arctic peatlands store large stocks of organic carbon which are vulnerable to the climate change but their fate is uncertain. There is increasing evidence that a part of it will be lost as a result of faster microbial mineralization. We studied the vulnerability of 3500-5900 years old bare peat uplifted from permafrost layers by cryogenic processes to the surface of an arctic peat plateau. We aimed to find biotic and abiotic drivers of CLOSS from old peat and compare them with those of adjacent, young vegetated soils of the peat plateau and mineral tundra. The soils were incubated in laboratory at three temperatures (4°C, 12°C and 20°C) and two oxygen levels (aerobic, anaerobic). CLOSS was …
Outcome of Refractory Anemia with Ringed Sideroblasts Associated with Marked Thrombocytosis (RARS-T) In a Large Cohort of Patients
2010
Abstract Abstract 4113 Introduction: Most of the data related to RARS-T, a rare disorder, involve small cohorts of patients. We aimed to analyze more patients also considering a variety of myelodysplastic or myeloproliferative disorders. Objective: To compare a large cohort of patients with RARS-T to refractory anemia with ringed sideroblasts (RARS), refractory anemia with ringed sideroblasts and multilineage dysplasia (RARS-MD) or essential thrombocythemia (ET) at the time of diagnosis and during disease evolution, in terms of survival and complications. Materials: Data of a European multi-center study was used including 199 cases of RARS-T 173 cases of RARS, 102 cases of RARS-MD and 431 c…
Classification, epidemiology, risk factors, and natural history of peripheral arterial disease.
2002
Peripheral arterial disease (PAD) is a clinical condition that has often been neglected. The clinical diagnosis of PAD may be made on the basis of an accurate history by using the WHO/Rose Questionnaire or the Edinburgh Questionnaire. From a clinical point of view, PAD may be classified into four stages. The PARTNERS Programme (PAD Awareness, Risk and Treatment: NEw Resources for Survival) is a recent study based on a partnership to improve PAD care. In this population, the prevalence of patients who were PAD+/CVD- was approximately 12% in males and 15% in females; PAD+/CVD+ approximately 18% in males and 14% in females; PAD-/CVD+ 28% in males and 17% in females; and finally, patients witho…
Nitric oxide synthase: expression and expressional control of the three isoforms.
1995
Three isozymes of nitric oxide synthase (NOS) have been identified. Their cDNA- and protein structures as well as their genomic DNA structures have been described. NOS I (ncNOS, originally discovered in neurons) and NOS III (ecNOS, originally discovered in endothelial cells) are low output, Ca(2+)-activated enzymes whose physiological function is signal transduction. NOS II (iNOS, originally discovered in cytokine-induced macrophages) is a high output enzyme which produces toxic amounts of NO that represent an important component of the antimicrobial, antiparasitic and antineoplastic activity of these cells. Depending on the species, NOS II activity is largely (human) or completely (mouse a…
Deformidad tipo Checkrein del Hállux y dedos menores del pie sin fractura previa asociada.
2020
espanolPresentamos una revision bibliografica y la descripcion de la tecnica quirurgica en la deformidad tipo Checkrein del hallux y dedos menores del pie. Esta deformidad dinamica provoca a los pacientes una dificultad significativa para caminar y les impide practicar cualquier deporte ya que en la fase de apoyo de la marcha los dedos del pie se ven forzados a una flexion plantar maxima y terminan atrapados debajo del pie. En los casos en que no se asocia a fractura osea la sospecha clinica causante de la lesion es un sindrome compartimental subclinico. El tratamiento descrito en este trabajo consiste en una plastia en Z y la aplicacion de una sutura pulvertaft en el flexor largo del hallu…
Intramuscular tramadol versus ketorolac in patients with orthopedic and traumatologic postoperative pain: a comparative multicenter trial
1998
This 3-day, multicenter, open-label, randomized, controlled trial was undertaken to assess the postoperative analgesic effect and therapeutic safety of intramuscular tramadol compared with intramuscular ketorolac in 48 patients undergoing orthopedic surgery and having postoperative pain assessed as 75 mm or more on a 100-mm visual analogue scale. Tramadol (100 mg/2 mL ampules) was administered as needed to a maximum of 400 mg/d, and ketorolac (30 mg/1 mL ampules) was given as needed up to 90 mg/d. Nine patients who received tramadol and six who received ketorolac needed only one dose of medication to achieve satisfactory analgesia. Tramadol had a more pronounced analgesic effect than did ke…
Structure of the phenylalanine hydroxylase gene in Drosophila melanogaster and evidence of alternative promoter usage.
1996
The complete Drosophila melanogaster phenylalanine hydroxylase gene isolated from a genomic library was sequenced. Gene structure consisted of five exons covering a region of around 3 kb. Position of introns in the C-terminal domain was conserved with mammalian aromatic amino acid hydroxylase genes. Putative promoter sequences in the 5'UTR and intron 1 were identified. A novel transcript was detected differing from that previously reported by the inclusion of a part of the intron 1 sequence. It could be produced using an alternative promoter. The deduced open reading frame would code a protein with a small difference at the N-terminus. Expression of the alternative transcripts was examined …
