Direct and indirect suppression of Scn5a gene expression mediates cardiac Na+ channel inhibition by Wnt signalling
ConclusionsWnt signalling inhibits Na+ channel by direct and indirect (via Tbx3) suppression of Scn5a transcription. Strategies to block TCF4 binding to Tbx3 and Scn5a promoters would represent novel strategies for cardiac-specific inhibition of Wnt pathway to rescue INa and prevent sudden cardiac deaths.
Publication date: Available online 14 December 2019Source: Microbiological ResearchAuthor(s): Man You, Shumei Fang, Jacqueline MacDonald, Jianping Xu, Ze-Chun YuanAbstractPlant-growth promoting rhizobacteria benefit crop health and growth through various mechanisms including phosphate and potassium solubilisation, and antimicrobial activity. Previously, we sequenced the genome of bacterial strain Burkholderia cenocepacia CR318, which was isolated from the roots of the starch corn (Zea mays L.) in London, Ontario, Canada. In this work, the species identity of this isolate is confirmed by recA phylogeny and in silico DNA-DNA...
ConclusionsThis baseline report reveals variations in dental diseases, oral hygiene practices, and dental treatments rendered before HSCT among different study centers. Establishment of an international standard of care for dental treatment before HSCT is needed. Prospective OraStem study data will increase the understanding of risk factors related to oral complications during HSCT.
This study describes orofacial features in 17 patients with WBS.
A 56-year-old white woman complained of "bleeding gum lesions." Previous medical history revealed systemic arterial hypertension, diabetes mellitus, cardiac arrhythmia, and surgery for a prosthetic heart valve placement. Oral examination showed 3 pedunculated nodules in the gingiva involving the 3 remaining upper teeth, about 1.5 cm in greatest diameter, with rapid growth and bleeding but otherwise asymptomatic. Diagnostic hypothesis was pyogenic granuloma. Complete blood count showed leukopenia and thrombocytopenia.
This study describes a 10-year-old male patient, clinically diagnosed as having SWB, with congenital aortic stenosis and mental retardation, who was followed up by a cardiologist, psychologist, geneticist, speech therapist, and physiotherapist.
The 22 q11.2 deletion syndrome, also known as DiGeorge syndrome, is the subject of the loss of a submicroscopic segment of DNA in the 22 q11.2 region. It presents a great variability of clinical characteristics in affected individuals. Among the clinical manifestations are fissure of the palate, nasal speech, cardiovascular problems, and dysmorphic facial features. This case report describes a 15-year-old girl, clinically diagnosed as having DiGeorge syndrome, who attended a dental service for patients with special needs presenting with malocclusion, difficulty in chewing, and suspected heart disease.
An 86-year-old man was evaluated complaining a painful lesion situated in the tongue with 45-day duration. Medical history revealed anemia, heart disease, vasculitis, and glomerulitis associated with the previous diagnosis of Wegener granulomatosis. Positive reaction for antineutrophil cytoplasmic autoantibodies (ANCA) was reported. Intraoral examination revealed an asymptomatic ulceration on the dorsum of the tongue surrounded by a whitish area that measures its 2.0 × 1.0 cm in its largest diameters.
Noonan syndrome with multiple giant cell lesions (NS/MGCLS) is a term used to describe a subgroup of people with Noonan syndrome, a rare condition with phenotypic overlap with NS. Once thought to be a specific and separate entity, it is now suggested to be a variant of the NS spectrum. Here we report a 22-year-old patient misdiagnosed as having Rubinstein-Taybi syndrome (microcephaly, congenital heart disease, ventricular septal defect, cryptorchidism, pterygium coli, inguinal hernia, and short stature and neck).
ConclusionsA predictive model of in-hospital mortality in left-sided IE based on the prognostic variables proposed by the European Society of Cardiology IE guidelines has high discriminatory ability.ResumenIntroducción y objetivosLa endocarditis infecciosa (EI) es una enfermedad compleja con elevada mortalidad. La evaluación pronóstica es esencial en el tratamiento de la enfermedad; sin embargo, las guías internacionales no aportan una evaluación objetiva del riesgo individual. Se desarrolló un modelo predictivo de mortalidad hospitalaria en EI izquierda combinando las variables pr...
ConclusionPatients with a delayed presentation after CS-STEMI were younger and more likely to have single-vessel disease. We found a high in-hospital mortality of 42.9%. Appropriate randomized studies are required to evaluate the optimal treatment strategies in these patients.
