Expanded CCUG repeat RNA expression in Drosophila heart and muscle trigger Myotonic Dystrophy type 1-like phenotypes and activate autophagocytosis ge…

2016

AbstractMyotonic dystrophies (DM1–2) are neuromuscular genetic disorders caused by the pathological expansion of untranslated microsatellites. DM1 and DM2, are caused by expanded CTG repeats in the 3′UTR of the DMPK gene and CCTG repeats in the first intron of the CNBP gene, respectively. Mutant RNAs containing expanded repeats are retained in the cell nucleus, where they sequester nuclear factors and cause alterations in RNA metabolism. However, for unknown reasons, DM1 is more severe than DM2. To study the differences and similarities in the pathogenesis of DM1 and DM2, we generated model flies by expressing pure expanded CUG ([250]×) or CCUG ([1100]×) repeats, respectively, and compared …

Influence of the anti-inflammatory cytokine interleukin-4 on human joint capsule myofibroblasts

2016

Post-traumatic joint contracture was reported to be associated with elevated numbers of contractile myofibroblasts (MFs) in the healing capsule. During the physiological healing process, the number of MFs declines; however, in fibroconnective disorders, MFs persist. The manifold interaction of the cytokines regulating the appearance and persistence of MFs in the pathogenesis of joint contracture remains to be elucidated. The objective of our current study was to analyze the impact of the anti-inflammatory cytokine interleukin (IL)-4 on functional behavior of MFs. Cells were isolated from human joint capsule specimens and challenged with three different concentrations of IL-4 with or without…

Transcriptional profiles from patients with dystrophinopathies and limb girdle muscular dystrophies as determined by qRT-PCR.

2003

Mutations in genes coding for the dystrophin-glycoprotein complex (DGC) cause inherited muscular dystrophies (MD), including Morbus Duchenne (DMD) and M. Becker (BMB) as well as limb-girdle muscular dystrophies (LGMD). New insights into the pathophysiology of the dystrophic muscle, the identification of compensatory mechanisms and additional proteins interacting with dystrophin are essential for developing new treatments. In order to define molecular mechanisms induced by lack of dystrophin and the subsequent counter-regulatory transcriptional response of degenerating muscle fibres, we have investigated the mRNA expression of 19 functionally linked genes in biopsies of patients with MD by m…

Plantar pressure distribution analysis in normal weight young women and men with normal and claw feet: a cross-sectional study

2005

We analyzed the plantar support in 72 normal-weight young voluntaries (46 women, 26 men), by a baropodometric platform. We considered subjects with claw foot (CFS) and subjects with normal foot (NFS). We found a significant reduction of total plantar support surface in the CFS (P < 0.0001 for women, P < 0.001 for men), due to the reduction of the forefoot and rear foot areas of both plantar imprints. Indeed, CFS of both sexes exhibited higher values of both plantar pressure and peak pressure, compared to the NFS. Moreover, the load per units of plantar surface increased in CFS compared to the NFS. In conclusion, the reduction of plantar support surfaces in CFS of both sexes was associated t…

Psychological variables and temporomandibular disorders: distress, coping, and personality.

2004

Abstract Objective This study analyzes the psychological variables of distress, personality, and coping that are related to the diagnosis based on the Research Diagnostic Criteria for temporomandibular disorder. Study design An age and sex-matched controlled study conducted with a convenience sample (n = 89) in a tertiary care facility. Results The MANCOVA between the muscular (n = 47), articular (n = 42), and control groups (n = 100) showed that the muscular group differed from the control group, obtaining higher levels of distress, anxiety, and depression, and minor use of positive reinterpretation and humor as coping strategies; the articular group also showed higher distress, less posit…

Reduction rate by decompression as a treatment of odontogenic cysts

2017

Background: Odontogenic cysts are defined as those cysts that arise from odontogenic epithelium and occur in the tooth-bearing regions of the jaws. Cystectomy, marsupialization or decompression of odontogenic cyst are treatment approach to this pathology. The aim of this study was to evaluate the effectiveness of the decompression as the primary treatment of the cystic lesions of the jaws and them reduction rates involving different factors. Material and Methods: 23 patients with odontogenic cysts of the jaws, previously diagnosed by anatomical histopathology (follicular cysts (7) and radicular cysts (16)) underwent decompression as an initial treatment. Clinical examination and pre and pos…

Rates of Upper Facet Joint Violation in Minimally Invasive Percutaneous and Open Instrumentation: A Comparative Cohort Study of Different Insertion T…

2017

Background Minimally invasive pedicle screw placement may have a higher incidence of violation of the superior cephalad unfused facet joint. Study Aims We investigated the incidence and risk factors of upper facet joint violation in percutaneous robot-assisted instrumentation versus percutaneous fluoroscopy-guided and open transpedicular instrumentation. Methods A retrospective study including all consecutive patients who underwent lumbar instrumentation, fusion, and decompression for spondylolisthetic stenosis and degenerative disk disease was conducted between January 2012 and January 2016. All operations were performed by the same surgeon; the patients were divided into three groups acc…

Manometric assessment of oesophageal involvement in progressive systemic sclerosis, morphoea and Raynaud's disease.

1982

SUMMARY Oesophageal function was studied by radiography and manometry in fifty-one patients with progressive systemic sclerosis (PSS), fourteen patients with morphoea, twelve patients with Raynaud's disease and twenty-one normal subjects. Upper oesophageal sphincter pressure was not affected. Peristaltic contractions of the upper third of the oesophagus were significantly decreased in PSS and morphoea, but the lower two-thirds were affected only in PSS. Lower oesophageal sphincter pressure was significantly decreased in PSS but was normal in morphoea and Raynaud's disease. There was a significant correlation between oesophageal dysfunction and the duration of PSS. Manometry was better than …

The biological anakinra appears promising to halt cytokine storm syndrome seen in severe courses of COVID-19. However, immunosuppression with anakinra may facilitate sepsis, necessitating continuous screening for bacterial superinfections.

Mouse CSB protein is important for gene expression in the presence of a single-strand break in the non-transcribed DNA strand.

2010

CSB protein is required for strand-specific repair of bulky DNA lesions in transcribed genes and mediates transcription recovery after exposure to DNA-damaging agents. We enzymatically generated DNA single-strand breaks (SSBs) with 3'-OH and 5'-phosphate termini in defined positions of a plasmid-borne gene and measured their effect on transcription in cell lines with different statuses of the Csb gene. A single SSB in the transcribed region of the gene caused significant decrease of gene expression. In all tested cell lines of mouse and human origin, a SSB in the transcribed DNA strand was less harmful for gene expression than a SSB situated in the opposing DNA strand. CSB deficiency exhibi…
