Not Only for Egg Yolk—Functional and Evolutionary Insights from Expression, Selection, and Structural Analyses of Formica Ant Vitellogenins

2014

Vitellogenin (Vg), a storage protein, has been extensively studied for its egg-yolk precursor role, and it has been suggested to be fundamentally involved in caste differences in social insects. More than one Vg copy has been reported in several oviparous species, including ants. However, the number and function of different Vgs, their phylogenetic relatedness, and their role in reproductive queens and nonreproductive workers have been studied in few species only. We studied caste-biased expression of Vgs in seven Formica ant species. Only one copy of conventional Vg was identified in Formica species, and three Vg homologs, derived from ancient duplications, which represent yet undiscovered…

Neuroprotective Properties of Mildronate, a Small Molecule, in a Rat Model of Parkinson’s Disease

2010

Previously, we have found that mildronate [3-(2,2,2-trimethylhydrazinium) propionate dihydrate], a small molecule with charged nitrogen and oxygen atoms, protects mitochondrial metabolism that is altered by inhibitors of complex I and has neuroprotective effects in an azidothymidine-neurotoxicity mouse model. In the present study, we investigated the effects of mildronate in a rat model of Parkinson’s disease (PD) that was generated via a unilateral intrastriatal injection of the neurotoxin 6-hydroxydopamine (6‑OHDA). We assessed the expression of cell biomarkers that are involved in signaling cascades and provide neural and glial integration: the neuronal marker TH (tyrosine hydroxylase); …

Early evaluation using a radiomic signature of unresectable hepatic metastases to predict outcome in patients with colorectal cancer treated with FOL…

2020

PurposeThe objective of this study was to build and validate a radiomic signature to predict early a poor outcome using baseline and 2-month evaluation CT and to compare it to the RECIST1·1 and morphological criteria defined by changes in homogeneity and borders.MethodsThis study is an ancillary study from the PRODIGE-9 multicentre prospective study for which 491 patients with metastatic colorectal cancer (mCRC) treated by 5-fluorouracil, leucovorin and irinotecan (FOLFIRI) and bevacizumab had been analysed. In 230 patients, computed texture analysis was performed on the dominant liver lesion (DLL) at baseline and 2 months after chemotherapy. RECIST1·1 evaluation was performed at 6 months. …

2003

To evaluate immune responses, safety and reactogenicity of the concomitant use of DTaP-IPV-Hib and the newly available 7-valent pneumococcal conjugate (7VPnC) vaccines when given as the primary immunization series in early infancy. A total of 231 healthy infants were enrolled at 11 German study centers and randomized to receive either 7VPnC plus DTaP-IPV-Hib vaccines concomitantly into opposite limbs at age 2, 3, 4 and 11-15 months (7VPnC group) or DTaP-IPV-Hib vaccine at the same ages plus a 7VPnC "catch-up vaccination" at ages 6, 7, 8 and 11-15 months (Control group). Blood samples were drawn before and 4 weeks after the first three vaccine doses and 4 weeks after the fourth dose. Local a…

Promoting Physical Activity Habits after Completing Secondary School: Does the Age Matter?

2022

Physical inactivity is one of the most important problems in our society, especially during adolescence. During this stage of schooling, students practice physical activity in physical education classes, but after they finish school, many of them stop practicing it. This research aims to determine which variables predict the intention to practice physical activity after finishing secondary school and to discover the effect that age during adolescence has on these predictive variables. A questionnaire was administered to a sample of secondary school students. The results show that physical exercise identity influences the three antecedents of this theory, while the attitude towards the behav…

New Hyperekplexia Mutations Provide Insight into Glycine Receptor Assembly, Trafficking, and Activation Mechanisms*

2013

Hyperekplexia is a syndrome of readily provoked startle responses, alongside episodic and generalized hypertonia, that presents within the first month of life. Inhibitory glycine receptors are pentameric ligand-gated ion channels with a definitive and clinically well stratified linkage to hyperekplexia. Most hyperekplexia cases are caused by mutations in the α1 subunit of the human glycine receptor (hGlyR) gene (GLRA1). Here we analyzed 68 new unrelated hyperekplexia probands for GLRA1 mutations and identified 19 mutations, of which 9 were novel. Electrophysiological analysis demonstrated that the dominant mutations p.Q226E, p.V280M, and p.R414H induced spontaneous channel activity, indicat…

Evaluation of the psychometric properties of “the Norwegian screening test for dyslexia”

2018

The aim of this study was to develop and investigate the psychometric properties of a screening protocol for Norwegian students in upper secondary school. The protocol was designed to assess skills that are at stake in dyslexia. It was administered to 232 students. In the absence of a “gold standard,” comparisons were made between students who reported normal literacy skills (n = 184) and literacy problems (n = 48). Significant group differences were found across all areas. Logistic regression and receiver operating characteristic curve analyses demonstrated good discriminatory power. The screening protocol met the standards for reliability and validity. It has the potential to be a useful …

Vorapaxar in the secondary prevention of atherothrombotic events

2012

BACKGROUND: Thrombin potently activates platelets through the protease-activated receptor PAR-1. Vorapaxar is a novel antiplatelet agent that selectively inhibits the cellular actions of thrombin through antagonism of PAR-1. METHODS: We randomly assigned 26,449 patients who had a history of myocardial infarction, ischemic stroke, or peripheral arterial disease to receive vorapaxar (2.5 mg daily) or matching placebo and followed them for a median of 30 months. The primary efficacy end point was the composite of death from cardiovascular causes, myocardial infarction, or stroke. After 2 years, the data and safety monitoring board recommended discontinuation of the study treatment in patients …

Transurethral incision of duplex system ureteroceles in neonates: does it increase the need for secondary surgery in intravesical and ectopic cases?

2004

OBJECTIVE To evaluate the relevance of ureterocele ectopia and associated reflux on the outcome of duplex system ureteroceles (DSU) after neonatal transurethral incision (TUI). PATIENTS AND METHODS The study included 41 neonates with a diagnosis of DSU; the ureterocele was ectopic in 24 (58%). Before TUI, vesico-ureteric reflux (VUR) was present in 13 lower moieties (32%) and seven contralateral ureters (17%). TUI was always performed within the first month of life. The follow-up and management were tailored for each patient from the findings at ultrasonography, voiding cysto-urethrography and renal scintigraphy. Results of intravesical and ectopic DSU were compared using Fisher's exact tes…
