Seasonal Distribution and Movement of the Invasive Pest Delottococcus aberiae (Hemiptera: Pseudococcidae) Within Citrus Tree: Implications for Its In…
2018
[EN] Delottococcus aberiae (De Lotto) (Hemiptera: Pseudococcidae) is the most recent species of mealybug introduced to Spain that is affecting citrus. The feeding behavior of D. aberiae causes severe direct damage to citrus fruits, distorting their shape and/or causing reduction in size. There is no information available regarding its distribution within the citrus trees. The main objective of this study was to describe the seasonal distribution of D. aberiae within citrus trees and its migration patterns on the plants. Ten citrus orchards from eastern Spain were periodically sampled during 3 yr. In each orchard, the mealybug was sampled in different infested strata (canopy, trunk, and soil…
No association between the cystatin C gene polymorphism and Alzheimer's disease: a case-control study in an Italian population.
2005
Cystatin C is an amyloidogenic protein found together with beta-amyloid in cerebral arteriolar walls of both patients with Alzheimer's Disease (AD) and conghopilic amyloid angiopathy. Several findings implicate cystatin C in the pathogenesis of vascular diseases. Recent genetic association studies proposed cystatin C gene (CST3) as a susceptibility factor for AD, although other reports did not replicate this finding. We conducted a case-control study including 192 probable AD cases and 192 age- and sex-matched controls to test the association between CST3 and AD. Possible interaction between CST3 and age at onset of AD or apolipoprotein E (APOE) was also examined. No significant differences…
Guideline on management of the acute asthma attack in children by Italian Society of Pediatrics
2018
Abstract Background Acute asthma attack is a frequent condition in children. It is one of the most common reasons for emergency department (ED) visit and hospitalization. Appropriate care is fundamental, considering both the high prevalence of asthma in children, and its life-threatening risks. Italian Society of Pediatrics recently issued a guideline on the management of acute asthma attack in children over age 2, in ambulatory and emergency department settings. Methods The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) methodology was adopted. A literature search was performed using the Cochrane Library and Medline/PubMed databases, retrieving studies in Englis…
Nonradioactive Detection of Differentially Expressed Genes Using Complex RNA or DNA Hybridization Probes
1999
The analysis of differential gene expression has become increasingly important in recent years. Typically, differentially expressed genes are identified in a primary screening procedure, yielding candidate genes whose differential expression has to be verified. We provide a highly sensitive, efficient and nonradioactive differential screening procedure to analyze numerous candidate genes in a single step. This comprises labeling of poly(A)+ RNA of the cell types analyzed with DIG Chem-Link and differential hybridization to the candidate genes fixed on dot blots. DIG Chem-Link allows, to our knowledge, for the first time efficient and direct nonradioactive labeling of RNA in vitro. Advantag…
Research in China
2009
My stay in China began in November 1985 with a lecture at the opening of the Max Planck Guest Laboratory in the Institute of Cell Biology at the Chinese Academy of Sciences (CAS) in Shanghai (Hennig, 2000). It marked the beginning of 23 years of research and teaching at the Institute of Cell Biology and other universities throughout China. > Looking back after 23 years, the changes that have taken place in China could not have been predicted in 1985… In January 2001, I accepted a long‐term lectureship offered by the German Academic Exchange Service (DAAD; Bonn, Germany), which, with further support from CAS, allowed me to create my own research group within the Shanghai Institutes for Biolo…
Solving Man-Induced Large-Scale Conservation Problems: The Spanish Imperial Eagle and Power Lines
2011
[Background] Man-induced mortality of birds caused by electrocution with poorly-designed pylons and power lines has been reported to be an important mortality factor that could become a major cause of population decline of one of the world rarest raptors, the Spanish imperial eagle (Aquila adalberti). Consequently it has resulted in an increasing awareness of this problem amongst land managers and the public at large, as well as increased research into the distribution of electrocution events and likely mitigation measures.
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…
Medical pre-hospital management reduces mortality in severe blunt trauma: a prospective epidemiological study
2011
International audience; INTRODUCTION: Severe blunt trauma is a leading cause of premature death and handicap. However, the benefit for the patient of pre-hospital management by emergency physicians remains controversial because it may delay admission to hospital. This study aimed to compare the impact of medical pre-hospital management performed by SMUR (Service Mobile d'Urgences et de Réanimation) with non-medical pre-hospital management provided by fire brigades (non-SMUR) on 30-day mortality. METHODS: The FIRST (French Intensive care Recorded in Severe Trauma) study is a multicenter cohort study on consecutive patients with severe blunt trauma requiring admission to university hospital i…
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…
