New polymorphisms of Vkork1 gene related to anticoagulant resistance of rats and mice in Italy.

Background: Anticoagulant rodenticides (ARs) are a very effective tool to control rodent pest populations. Nevertheless, AR resistance has been documented worldwide. ARs block the cycle of vitamin K, leading to the death of the animal by internal bleeding: mutations in Vkorc1 gene can cause resistance.

Left atrium veno-arterial extra corporeal membrane oxygenation as temporary mechanical support for cardiogenic shock: A case report.

Background: Veno-arterial extra corporeal membrane oxygenation (VA-ECMO) support is commonly complicated with left ventricle (LV) distension in patients with cardiogenic shock. We resolved this problem by transeptally converting VA-ECMO to left atrium veno-arterial (LAVA)-ECMO that functioned as a temporary paracorporeal left ventricular assist device to resolve LV distension. In our case LAVA-ECMO was also functioning as a bridge-to-transplant device, a technique that has been scarcely reported in the literature.

Efficacy Evaluation of Oregano Essential Oil Mixed with and Diflubenzuron against and in Road Drains of Italy.

Mosquito management programs in the urban environment of Italian cities mainly rely on larval control with conventional insecticides, primarily targeting the road drains that constitute the principal mosquito breeding sites encountered in public. The repeated utilization of synthetic insecticides may have adverse effects on non-targets and lead to resistance development issues, while the performance of biopesticides encounters limitations in field use. Botanical insecticides as single larval control agents or in binary mixtures with conventional insecticides have been extensively studied in the laboratory as an effective and eco-friendly alternative mosquito control method with promising results.

Use of non-surgical aesthetic refinement after orthognathic surgery: Case studies.

Orthognathic surgery has an undeniable functional effect, but the aesthetic result must not be disregarded, especially since many patients visit the surgeon precisely because of an aesthetic complaint and ignore the practical benefits. The aim of this paper is to discuss about an ideal treatment that combines this functional improvement with facial aesthetics and improves it after the operation. In order to predict which aesthetic deficits may occur, a facial analysis is essential.

A Novel Allele Specific Polymerase Chain Reaction (AS-PCR) Assay to Detect the V1016G Knockdown Resistance Mutation Confirms Its Widespread Presence in Populations from Italy.

Polymerase chain reaction (PCR)-based genotyping of mutations in the voltage-sensitive sodium channel () associated with resistance to pyrethroid insecticides is widely used and represents a potential early warning and monitoring system for insecticide resistance arising in mosquito populations, which are vectors of different human pathogens. In the secondary vector -an Asian species that has invaded and colonized the whole world, including temperate regions-sequencing of domain II of the gene is still needed to detect the V1016G mutation associated with pyrethroid resistance. In this study we developed and tested a novel allele-specific PCR (AS-PCR) assay to genotype the V1016G mutation in this species and applied it to the analysis of wild populations from Italy.

Seroprevalence of hepatitis E virus in dogs in Switzerland.

Hepatitis E virus (HEV) is the causative agent of an acute and in most cases self-limiting hepatitis. Of the four major HEV genotypes that infect humans, genotype 3 and 4 are zoonotic and have been identified in humans but predominantly in pigs and wild boar, which are considered the main reservoirs. However, the known host range of zoonotic HEV may be increasing to comprise additional species, including companion animals.

Evaluation of the Pharmacophoric Role of the O-O Bond in Synthetic Antileishmanial Compounds: Comparison between 1,2-Dioxanes and Tetrahydropyrans.

Leishmaniases are neglected diseases that can be treated with a limited drug arsenal; the development of new molecules is therefore a priority. Recent evidence indicates that endoperoxides, including artemisinin and its derivatives, possess antileishmanial activity. Here, 1,2-dioxanes were synthesized with their corresponding tetrahydropyrans lacking the peroxide bridge, to ascertain if this group is a key pharmacophoric requirement for the antileishmanial bioactivity.

Comparative study on the effectiveness of different mosquito traps in arbovirus surveillance with a focus on WNV detection.

The selection of the ideal trap for arbovirus surveillance is an issue of primary importance to increase the sensitivity of virus detection and the cost-effectiveness of the entomological surveillance. During the summer 2011, the effectiveness of five types of mosquito traps (CDC gravid trap, CO2(-)baited trap, BG-Sentinel™ and two experimental prototypes) to attract females potentially infected with West Nile virus were assessed. The study was carried out in three natural wetland sites located in the Emilia-Romagna Region (Northern Italy), using a Latin square scheme.

Macrocyclops albidus (Copepoda: cyclopidae) for the Biocontrol of Aedes albopictus and Culex pipiens in Italy.

The aim of our study was to assess the potential of Macrocyclops albidus as a biological control agent against the 1st and 2nd instars of Culex pipiens and Aedes albopictus. Under laboratory conditions of prey saturation (50 1st instars/copepod), an average of 58.98% of Cx.

Onion skin technique for open surgical replacement of aortic arch following primary endoprothesic thoracic aorta treatment.

Endovascular aortic replacement (EVAR) techniques have become the first choice option for many aortic diseases in patients in whom standard open surgery was contraindicated or with high surgical risk. A secondary open surgical treatment, following a primary EVAR procedure, could, however, be challenging depending on the type, the extension and the position of primary endoprosthesis. Here, we describe an original and easy technique capable of simplifying a secondary aortic arch replacement following EVAR treatment of the descending thoracic aorta.

Mating competitiveness of Aedes albopictus radio-sterilized males in large enclosures exposed to natural conditions.

Mating competitiveness trials have been conducted in large net-screened enclosures (8 by 5 by 2.8 m) built in a natural shaded environment, in the summers of 2006, 2007, 2008, and 2009 in northern Italy. Aedes albopictus (Skuse) males were radio-sterilized by applying gamma radiations at doses in the range 30-60 Gy.

Seasonal pattern of daily activity of Aedes caspius, Aedes detritus, Culex modestus, and Culex pipiens in the Po Delta of northern Italy and significance for vector-borne disease risk assessment.

The increasing concern about vector-borne diseases such as West Nile disease in northern Italy motivated our analysis of data on the mosquito fauna and the seasonal and daily flight patterns collected in 1998 in the Po Valley. Collections were performed once a week from May to November, with human landing collections and CO(2) traps. Culex pipiens was present from July to October and showed a clearly unimodal nocturnal flight habit.

Arboviral survey of mosquitoes in two northern Italian regions in 2007 and 2008.

Recently, Italy-particularly the Emilia-Romagna region-was the location of consecutive outbreaks of human diseases caused by the arboviruses chikungunya virus and West Nile virus. The two outbreaks, spread by different species of mosquitoes, were not related, but pointed out the lack of an arboviral surveillance program in this region. Beginning in 2007 entomological surveillance was initiated in the Emilia-Romagna region, and in 2008 the program was improved and extended at Lombardia region.

A regional plan of the Emilia-Romagna regional bureau for Aedes albopictus control--year 2008.

Following the outbreak of Chikungunya virus fever occurred in the summer 2007 in Emila Romagna (an administrative region located along the Adriatic (East) coast of Italy) a regional plan for Aedes albopicus control has been implemented. The major items of the plan are here reported and discussed.

Right ventricular failure after left ventricular assist device insertion: preoperative risk factors.

Right ventricular failure after left ventricular assist device placement is the major concern on weaning from cardiopulmonary bypass and it is one of the most serious complications in the postoperative period. This complication has a poor prognosis and is generally unpredictable. The identification of pre-operative risk factor for this serious complication is incomplete yet.

The need for inotropic drugs in anesthesiology and intensive care.

The management of the failing heart represents an increasingly frequent challenge to both anesthesiologists and intensive care physicians, due to the increased prevalence of ventricular dysfunction in the population and to the ever-expanding indications for the surgical treatment of cardiac disease. Inotropic drugs are nowadays invaluable therapeutic tools in the treatment of perioperative heart failure and of the different forms of heart failure found in intensive care unit clinical practice. Postoperative myocardial dysfunction is a major concern in the setting of cardiac surgery since it is extremely frequent and is related to a greater morbidity and mortality.

Influence of underlying lung disease on early postoperative course after single lung transplantation.

Background: Single lung transplantation can be a suitable therapeutic option for a wide range of end-stage lung diseases: pulmonary fibrosis, emphysema, primary pulmonary hypertension and Eisenmenger's syndrome. Yet, patients suffering from different diseases have significantly different cardiovascular and respiratory functional profiles that can exert a profound influence on their response to the perioperative procedures. Our purpose is to analyze whether the patient's underlying disease can influence the early postoperative outcome after single lung transplantation.

[Single lung transplantation retrospective analysis of intraoperative cardiovascular problems].

Background: Analysis of haemodynamic problems during single-lung transplantation and of methodologies employed for their treatment.

Design Of The Study: clinical retrospective study.

Setting: General University Hospital.

Molecular epidemiology of human T-cell leukemia virus type I (HTLV-1) Brazil: the predominant HTLV-1s in South America differ from HTLV-ls of Japan and Africa, as well as those of Japanese immigrants and their relatives in Brazil.

To better understand the origin of human T-cell leukemia virus type l (HTLV-l) in South America, we conducted a phylogenetic study on 27 new HTLV-ls in Brazil. These were obtained from Brazilians of various ethnic origins, such as Japanese immigrants, whites, blacks and mulattos. We amplified and sequenced proviral DNAs of a part of the long terminal repeats.

Acute effects of inhaled nitric oxide in adult respiratory distress syndrome.

This study evaluated the dose-response effect of inhaled nitric oxide (NO) on gas exchange, haemodynamics, and respiratory mechanics in patients with adult respiratory distress syndrome (ARDS). Of 19 consecutive ARDS patients on mechanical ventilation, eight (42%) responded to a test of 10 parts per million (ppm) NO inhalation with a 25% increase in arterial oxygen tension (Pa,O2,) over the baseline value. The eight NO-responders were extensively studied during administration of seven inhaled NO doses: 0.
