Similar contributions of BRCA1 and BRCA2 germline mutations to early-onset breast cancer in Germany.

2003

This study was undertaken to investigate the prevalence of BRCA1 and BRCA2 germline mutations in 91 German patients unselected for family history, who were diagnosed with breast cancer before the age of 41 years. Clinical information and blood samples were obtained from all patients. A comprehensive BRCA1 and BRCA2 mutational analysis was performed using the protein truncation assay and single-strand conformational polymorphism analysis followed by DNA sequencing of variant signals detected by these assays. Five different deleterious germline mutations including four frameshift mutations and one missense mutation were identified, three in BRCA1 (3.3%) and two mutations (2.2%) in BRCA2. Both…

Complications following the use of alloplastic materials in urogynecological surgery

2011

Abstract Study design 118 patients, who were admitted from 2005 to 2008 to our department due to complications following mesh implantation, were included in a retrospective survey. We investigated patient symptoms, findings and subsequent patient management. There was a re-evaluation of symptoms in a follow-up eight weeks after the revision procedure. Data from our urogynecological file archive were used. Results The main complaints were de novo urgency, pain and recurrent urinary tract infections. The main findings were mesh erosion and infections including abscess formations and osteomyelitis. Before being admitted to our department, 42 patients (35.6%) had already undergone at least one …

The improvement of quality of life a indication for elective surgery in elderly patients with minimally symptomatic inguinal hernia.

2014

AIM: Effectiveness of surgery on quality of life in elderly affected by minimally symptomatic inguinal hernia. MATERIAL OF STUDY: Forty male patients aging over 75 years affected by minimally symptomatic inguinal hernia were included. In the first group were allocated 15 patients who refused hernioplasty; in the second were included 25 patients who underwent early elective hernioplasty using an high density polypropylene mesh under local anesthesia. The SF-36 questionnaire was administered to all patients at the time of enrollment and 6 months after. RESULTS: All 8 domains of SF-36 and his related two comprhensive index, Mental Component Summary and Physical Component Summary scores, improv…

Endothelin Antagonism: Effects of FP Receptor Agonists Prostaglandin F2αand Fluprostenol on Trabecular Meshwork Contractility

2006

Purpose This study analyzes additional mechanisms behind the ocular hypotensive effect of prostaglandin F (PGF) receptor (FP receptor) agonists PGF2alpha and fluprostenol (fluprostenol-isopropyl ester [travoprost]), which reduce intraocular pressure (IOP) in patients with glaucoma probably by enhancing uveoscleral flow. The trabecular meshwork (TM) is actively involved in IOP regulation through contractile mechanisms. Contractility of TM is induced by endothelin (ET)-1, a possible pathogenic factor in glaucoma. The involvement of FP receptor agonists in the ET-1 effects on TM function was studied. Methods The effects of FP receptor agonists on contractility of bovine TM (BTM) were investiga…

Prevalence and genetic diversity of Aichi virus strains in stool samples from community and hospitalized patients.

2008

ABSTRACT Aichi virus has been proposed as a causative agent of gastroenteritis. A total of 457 stool specimens from children hospitalized with acute diarrhea and 566 stool specimens from adults and children involved in 110 gastroenteritis outbreaks were screened for the presence of Aichi virus by reverse transcription-PCR (RT-PCR) amplification of the genomic region of the 3C and 3D (3CD) nonstructural proteins. Our results show a low incidence of Aichi virus in pediatric samples and the existence of mixed infections with other microbiological agents in some cases. From the outbreak survey, it appears that the presence of Aichi virus is an indicator of mixed infections causing gastroenterit…

Paths Coloring Algorithms in Mesh Networks

2003

In this paper, we will consider the problem of coloring directed paths on a mesh network. A natural application of this graph problem is WDM-routing in all-optical networks. Our main result is a simple 4-approximation algorithm for coloring line-column paths on a mesh. We also present sharper results when there is a restriction on the path lengths. Moreover, we show that these results can be extended to toroidal meshes and to line-column or column-line paths.

Personalized medicine for allergy treatment: Allergen immunotherapy still a unique and unmatched model

2021

International audience; The introduction of personalized medicine (PM) has been a milestone in the history of medical therapy, because it has revolutionized the previous approach of treating the disease with that of treating the patient. It is known today that diseases can occur in different genetic variants, making specific treatments of proven efficacy necessary for a given endotype. Allergic diseases are particularly suitable for PM, because they meet the therapeutic success requirements, including a known molecular mechanism of the disease, a diagnostic tool for such disease, and a treatment blocking the mechanism. The stakes of PM in allergic patients are molecular diagnostics, to dete…

A marching-on in time meshless kernel based solver for full-wave electromagnetic simulation

2012

A meshless particle method based on an unconditionally stable time domain numerical scheme, oriented to electromagnetic transient simulations, is presented. The proposed scheme improves the smoothed particle electromagnetics method, already developed by the authors. The time stepping is approached by using the alternating directions implicit finite difference scheme, in a leapfrog way. The proposed formulation is used in order to efficiently overcome the stability relation constraint of explicit schemes. In fact, due to this constraint, large time steps cannot be used with small space steps and vice-versa. The same stability relation holds when the meshless formulation is applied together w…

Glycogen synthase 2 is a novel target gene of peroxisome proliferator-activated receptors.

2007

International audience; Glycogen synthase 2 (Gys-2) is the ratelimiting enzyme in the storage of glycogen in liver and adipose tissue, yet little is known about regulation of Gys-2 transcription. The peroxisome proliferator-activated receptors (PPARs) are transcription factors involved in the regulation of lipid and glucose metabolism and might be hypothesized to govern glycogen synthesis as well. Here, we show that Gys-2 is a direct target gene of PPARalpha, PPARbeta/delta and PPARgamma. Expression of Gys-2 is significantly reduced in adipose tissue of PPARalpha-/-, PPARbeta/delta-/- and PPARgamma+/- mice. Furthermore, synthetic PPARbeta/delta, and gamma agonists markedly up-regulate Gys-2…
