The Drosophila Cystoblast Differentiation Factor, benign gonial cell neoplasm, Is Related to DExH-box Proteins and Interacts Genetically With bag-of-…
2000
Abstract Selection of asymmetric cell fates can involve both intrinsic and extrinsic factors. Previously we have identified the bag-of-marbles (bam) gene as an intrinsic factor for cystoblast fate in Drosophila germline cells and shown that it requires active product from the benign gonial cell neoplasm (bgcn) gene. Here we present the cloning and characterization of bgcn. The predicted Bgcn protein is related to the DExH-box family of RNA-dependent helicases but lacks critical residues for ATPase and helicase functions. Expression of the bgcn gene is extremely limited in ovaries but, significantly, bgcn mRNA is expressed in a very limited number of germline cells, including the stem cells.…
Rapid cloning of cDNA ends polymerase chain reaction of G-protein-coupled receptor kinase 6: an improved method to determine 5′- and 3′-cDNA ends
1999
Abstract Rapid cloning of 5′- and 3′-cDNA ends polymerase chain reaction (5′-/3′-RACE-PCR) is useful to determine unknown 5′- and 3′-cDNA termini. Even if the method can yield complete cDNA sequences within a couple of days, the RACE procedure bears some characteristic traps and often results in amplification of unspecific PCR-products. Here we used improved 5′- and 3′-RACE-PCR protocols to obtain the complete cDNA sequence of the G-protein-coupled receptor kinase 6 (GRK6) from a rat brain cDNA library. The use of an anchored oligo-(dT) 16 -V-primer in the cDNA synthesis, the addition of single-sided PCR steps prior to the RACE-PCRs and the optimization of the dA-tailing reaction conditions…
Health literacy supports active aging
2020
From the individual viewpoint, active aging refers to the ability of older persons, depending on their goals, functional capacity and opportunities, to engage in desired activities. This study investigated the role of health literacy in active aging among persons differing in their number of chronic conditions. Data were collected from 948 individuals, 57% women, aged 75, 80 and 85 in 2017–2018 in the city of Jyväskylä in Central Finland. Health literacy was assessed with the 16-question version of the European Health Literacy Survey (HLS-EU-Q16), active aging with the University of Jyväskylä Active Aging Scale (UJACAS) and self-reported physician-diagnosed chronic conditions. Both health l…
Bifid mandibular condyles: A systematic review.
2018
Background Bifid mandibular condyle (BMC) constitutes an extremely rare disorder characterized by a duplication of the head of the mandibular condyle. Its prevalence ranges from 0.31% to 1.82% in the published literature. Objectives The primary objective was to describe the main etiological, clinical and radiological characteristics of patients with BMCs and the existent treatment options. The secondary objective was to simultaneously include the characteristics of two new cases of BMC. Material and Methods An electronic search in Pubmed (MEDLINE), Scopus and The Cochrane Library was carried out by two independent reviewers until April 2018. Prospective or retrospective cohort studies, case…
Discover cervical disc arthroplasty versus anterior cervical discectomy and fusion in symptomatic cervical disc diseases: A meta-analysis.
2016
OBJECTIVE:Symptomatic cervical disc disease (SCDD) is a common degenerative disease, and Discover artificial cervical disc, a new-generation nonconstrained artificial disk, has been developed and performed gradually to treat it. We performed this meta-analysis to compare the efficacy and safety between Discover cervical disc arthroplasty (DCDA) and anterior cervical discectomy and fusion (ACDF) for SCDD. METHODS:An exhaustive literature search of PubMed, EMBASE, and the Cochrane Library was conducted to identify randomized controlled trials that compared DCDA with ACDF for patients suffering SCDD. A random-effect model was used. Results were reported as standardized mean difference or risk …
Tumor-associated autoantibody signature for the early detection of gastric cancer
2012
Autoantibodies against tumor-associated antigens are very attractive biomarkers for the development of noninvasive serological tests for the early detection of cancer because of their specificity and stability in the sera. In our study, we applied T7 phage display-based serological analysis of recombinant cDNA expression libraries technique to identify a representative set of antigens eliciting humoral responses in patients with gastric cancer (GC), produced phage-antigen microarrays and exploited them for the survey of autoantibody repertoire in patients with GC and inflammatory diseases. We developed procedures for data normalization and cutoff determination to define sero-positive signal…
Sequence of a novel cytochrome CYP2B cDNA coding for a protein which is expressed in a sebaceous gland, but not in the liver
1992
The major phenobarbital-inducible rat hepatic cytochromes P-450, CYP2B1 and CYP2B2, are the paradigmatic members of a cytochrome P-450 gene subfamily that contains at least seven additional members. Specific oligonucleotide probes for these genomic members of the CYP2B subfamily were used to assess their tissue-specific expression. In Northern-blot analysis a probe specific to gene 4 (which is designated now as CYP2B12) hybridized to a single mRNA present in the preputial gland, an organ which is used as a model for sebaceous glands, but did not hybridize to mRNA isolated from the liver or from five other tissues of untreated or Aroclor 1254-treated rats. The cDNA sequence for the CYP2B12 R…
Anatomy online: presentation of a detailed WWW atlas of human gross anatomy--reference for medical education.
2002
We present an online anatomy atlas based on the Visible Human Project (VHP) of the US National Library of Medicine. The objective is to provide original unlabeled as well as labeled sections of the human body of high quality and resolution on the Internet, for use in basic and continuing medical education. For a representative overview of the body, 370 axial sections were selected from the male and female data base of the VHP with special regard to regions of clinical interest. Each section is accompanied by its corresponding computer tomography (CT) image and, if available, magnetic resonance images (MRI) for quick and easy comparison of morphologic and radiologic structures. The sections …
A contemporary assessment of nocturia: definition, epidemiology, pathophysiology, and management--a systematic review and meta-analysis
2012
Abstract Context Nocturia is a common urologic symptom that has been covered in a variety of reported studies in the literature but is not specifically covered in current guidelines. Objective To comprehensively review the literature pertaining to the definition, etiologies, and consequences of nocturia and assess the evidence supporting the use of conservative medical and interventional therapy. Evidence acquisition A literature search was conducted using the keyword nocturia , restricted to articles in the English language, after 2000 and before April 2012, in PubMed/Medline, Embase, Scopus, Web of Science, and Cochrane Library databases. Regarding treatment modalities, studies were inclu…
Lack of efficacy of resveratrol on C-reactive protein and selected cardiovascular risk factors — Results from a systematic review and meta-analysis o…
2015
Introduction: Numerous studies have suggested that oral supplementation with resveratrol exerts cardioprotective effects, but evidence of the effects on C-reactive protein (CRP) plasma levels and other cardiovascular (CV) risk factors is inconclusive. Therefore, we performed a meta-analysis to evaluate the efficacy of resveratrol supplementation on plasma CRP concentrations and selected predictors of CV risk. Methods:The searchincludedPUBMED,Cochrane Library,Web ofScience,Scopus,andEMBASE(up toAugust31, 2014) to identify RCTs investigating the effects of resveratrol supplementation on selected CV risk factors. Quantitative data synthesis was performed using a random-effects model, with weig…
