Marfan syndrome (MFS) is an autosomal dominant disease of the connective tissue that affects the ocular, skeletal and cardiovascular systems, with a wide clinical variability. Although mutations in the FBN1 gene have been recognized as the cause of the disease, more recently other loci have been associated with MFS, indicating the genetic heterogeneity of this disease. We addressed the issue of...

Antibiotic resistance Staphylococcus aureus strains cause several life threatening infections. New drug treatment options are needed, but are slow to develop because 50% of the S. aureus genome is hypothetical. The goal of this is to aid in the annotation of the S. aureus NCTC 8325 genome by identifying hypothetical proteins related to the Major Facilitator Superfamily (MFS). The MFS is a broad...

BACKGROUND We used structural equation modeling to evaluate the quality of life (QOL) for patients with Marfan syndrome (MFS). The goal was to provide guidelines to facilitate the development of interventions and strategies to improve the QOL for patients with MFS. METHODS The participants fulfilled the Ghent 2 criteria for MFS and they comprised patients who visited the cardiology outpatient...

Marfan syndrome (MFS) is an autosomal dominant disorder of connective tissue, caused by mutations of the microfibrillar protein fibrillin-1, that predisposes affected individuals to aortic aneurysm and rupture and is associated with increased TGFβ signaling. TGFβ is secreted from cells as a latent complex consisting of TGFβ, the TGFβ propeptide, and a molecule of latent TGFβ binding protein (LT...

Cardiac fibroblasts (CFs) phenotypic conversion to myofibroblasts (MFs) represents a crucial event in cardiac fibrosis that leads to impaired cardiac function. However, regulation of this phenotypic transformation remains unclear. Here, we showed that sirtuin-7 (Sirt7) plays an important role in the regulation of MFs differentiation. Sirt7 expression and phosphorylation were upregulated in CFs ...

Microfilaments (MFs) play an important role in wound healing and other regenerative events. The purpose of this study was to characterize changes in the distribution of MFs in traumatized auditory epithelia and compare these changes between avian (regenerating) and mammalian (nonregenerating) ears. Chicks and guinea pigs were acoustically overstimulated and their auditory epithelia analyzed flu...

background. the aim of this study was to investigate myofibroblast (mf) density in a broad spectrum of odontogenic cysts and tumors and the relation between the density of mfs and the clinical behavior of these lesions. methods. a total of 105 cases of odontogenic lesions, including unicystic ameloblastoma (uam), solid ameloblastoma (sa), odontogenic keratocyst (okc), dentigerous cyst (dc), rad...

E. coli YbgH belongs to the family of proton-dependent oligopeptide transporters (POTs), a subfamily of the major facilitator superfamily (MFS) of secondary active transporters. Like other MFS transporters, POT proteins switch between two major conformations during substrate transport. Apart from possessing a canonical 12-helix, two-domain transmembrane (TM) core, prokaryotic POT proteins usual...

Seven patients with Miller Fisher syndrome (MFS), six in the acute phase and one in the recovery phase, were investigated for serum antibodies against gangliosides and purified lipopolysaccharides (LPS) from different strains of Campylobacter jejuni, including the MFS-associated serotypes O:2 and O:23. Immunoglobulin G antibodies against gangliosides GT1a and GQ1b were found in five of six pati...

Purpose: To report two patients with spontaneous scleral perforation and bleb formation associated with Marfan syndrome (MFS); which one of them also showed bilateral optic nerve dural ectasia. Case reports: An 11-year-old girl was referred with progressive myopia. Past medical history was negative. Slit-lamp examination revealed bilateral scleral thinning and perforation with bleb formation, s...
