In vitro comparative study on the friction of stainless steel wires with and without Orthospeed (JAL 90458) on an inclined plane
2016
Background: During the treatment of orthodontics, in the mechanics of slide, there takes place friction, which they reduce the slide of the arch across bracket. Therefore, clinical there takes place an increase of the time of treatment. There are different the technologies that try to reduce this friction, as the self-ligating braces. The purpose of this study was to research the in vitro behavior of JAL 90458 as a buffering agent which reduces friction between brackets and stainless steel arch wires of different cross sections and sizes. Material and Methods: Three types of stainless steel wires with different cross sections and three types of ligatures were used with and without JAL 90458…
Effects of barbell back squat stance width on sagittal and frontal hip & knee kinetics
2019
Different stance widths are commonly utilized when completing the barbell back squat during athletic general preparedness training. Width manipulation is thought to influence sagittal plane stimuli to the hip and knee extensors, the primary extensor musculature in the squat. However, how width manipulation affects frontal plane stimuli is less understood. Knowledge of hip and knee net joint moments (NJM) could improve exercise selection when aiming to improve sport‐specific performance and prevent injuries. Fourteen adult amateur rugby athletes were recruited for this study. After a familiarization period, participants performed wide‐ (WIDE, 1.5× greater trochanter width) and narrow‐stance …
A possible susceptibility locus for bipolar affective disorder in chromosomal region 10q25--q26.
2000
In an attempt to identify susceptibility loci for bipolar affective disorder, we are currently conducting a systematic genome screen with highly polymorphic microsatellite markers at an average marker spacing of 10 cM in a series of 75 families, comprising 66 families from Germany, eight families from Israel, and one family from Italy. The families were ascertained through index cases with bipolar affective disorder. The distribution of diagnoses is as follows: 126 individuals with bipolar I disorder, 40 with bipolar II disorder, 14 with schizoaffective disorder of the bipolar type, 40 individuals with recurrent unipolar depression, 51 with a minor psychiatric diagnosis, and two individuals…
A global DNA repair mechanism involving the Cockayne syndrome B (CSB) gene product can prevent the in vivo accumulation of endogenous oxidative DNA b…
2002
The Cockayne syndrome B (CSB) gene product is involved in the repair of various types of base modifications in actively transcribed DNA sequences. To investigate its significance for the repair of endogenous oxidative DNA damage, homozygous csb(-/-)/ogg1(-/-) double knockout mice were generated. These combine the deficiency of CSB with that of OGG1, a gene coding for the mammalian repair glycosylase that initiates the base excision repair of 7,8-dihydro-8-oxoguanine (8-oxoG). Compared to ogg1(-/-) mice, csb(-/-)/ogg1(-/-) mice were found to accumulate with age severalfold higher levels of oxidited purine modifications in hepatocytes, splenocytes and kidney cells. In contrast, the basal (ste…
The Skull in Achondroplasia
1988
The growth disorder in achondroplasia results from abnormalities of endochondral bone formation. Cranial abnormalities originate from the occipital bone, the only region where enchondral bone is formed.
Molecular Effects of the CTG Repeats in Mutant Dystrophia Myotonica Protein Kinase Gene
2008
Myotonic Dystrophy type 1 (DM1) is a multi-system disorder characterized by muscle wasting, myotonia, cardiac conduction defects, cataracts, and neuropsychological dysfunction. DM1 is caused by expansion of a CTG repeat in the 3 untranslated region (UTR) of the Dystrophia Myotonica Protein Kinase (DMPK) gene. A body of work demonstrates that DMPK mRNAs containing abnormally expanded CUG repeats are toxic to several cell types. A core mechanism underlying symptoms of DM1 is that mutant DMPK RNA interferes with the developmentally regulated alternative splicing of defined pre-mRNAs. Expanded CUG repeats fold into ds(CUG) hairpins that sequester nuclear proteins including human Muscleblind-lik…

Artropatía neuropática diabética del tobillo
1986
An unusual localisation of Charcot's joint disease is the ankle. A 31 year old patient developped a Charcot's joint after a trivial trauma, the spontaneus fracture of the tallus was followed by a quick joint destroy.
The effects of post-translational processing on dystroglycan synthesis and trafficking1
2003
Dystroglycan is a component of the dystrophin glycoprotein complex that is cleaved into two polypeptides by an unidentified protease. To determine the role of post-translational processing on dystroglycan synthesis and trafficking we expressed the dystroglycan precursor and mutants thereof in a heterologous system. A point mutant in the processing site, S655A, prevented proteolytic cleavage but had no effect upon the surface localisation of dystroglycan. Mutation of two N-linked glycosylation sites that flank the cleavage site inhibited proteolytic processing of the precursor. Furthermore, chemical inhibition of N- and O-linked glycosylation interfered with the processing of the precursor a…
Multiplex Ligation-dependent Probe Amplification (MLPA)
2011
The Multiplex Ligation-dependent Probe Amplification (MLPA) is a PCR-based method. The procedure relies on sequence-specific probe hybridization of genomic DNA, followed by multiplex-PCR amplification of the hybridized probe and a semiquantitative analysis of the resulting PCR products. MLPA allows the analysis of around 40 loci in the same reaction, and is a sensitive and relatively fast technique. Only a small amount of DNA is required and results are available within 2 days.The critical factors when performing MLPA analyses from formalin-fixed paraffin-embedded (FFPE) tissues are DNA integrity and purity; for this reason, a suitable DNA extraction method must be chosen.The MLPA protocol …
