Chagas' disease is the most important endemic arthropod-zoonosis in Argentina with an estimated 1.6 million people infected with the causative agent Trypanosoma cruzi. Triatoma infestans is the main vector of Chagas' disease in Argentina. A survey for parasites and pathogens of Triatominae was conducted from August 2002 to February 2005. Collections of insects were made in domiciles, peridomici...

Cotton (Gossypium spp.) is a major source of natural fiber and an important cash crop. The cotton growth habit architecture determine its productivity influence management strategies for commercial production. GATA transcription factors (TFs) control various developmental processes in plants, such as flower, bract embryo development, petal differentiation. As stable transformation still bottlen...

Abstract Background Coronavirus disease 2019 is a systemic entity, where cardiac involvement has been described. The echocardiogram diagnostic tool that describes myocardial damage with good certainty. Objectives Determine which echocardiographic parameters are predictors of mortality. Analyze if there difference in clinical, laboratory and variables terms patients who died versus those survive...

Introdução: Embora um maior comprometimento sensorial e motor após o Acidente Vascular Cerebral (AVC) ocorra no lado corporal contralateral à lesão cerebral, têm sido relatado comprometimentos do ipsilateral. No entanto, as características desse não estão claras.Objetivo: Avaliar Tempo de Reação (TR) simples membro superior ipsilateral em indivíduos com hemiparesia pós-AVC.Métodos: Ao todo, for...

Ecological soil-screening levels (Eco-SSLs) were developed by the United States Environmental Protection Agency (USEPA) for the purposes of setting conservative soil screening values that can be used to eliminate the need for further ecological assessment for specific analytes at a given site. Ecological soil-screening levels for wildlife represent a simplified dietary exposure model solved in ...

BACKGROUND Accurate evaluation of the tricuspid regurgitant (TR) spectral Doppler signal is important during transthoracic echocardiographic (TTE) evaluation for pulmonary hypertension (PHT). Contrast enhancement improves Doppler backscatter. However, its incremental benefit with contemporary scanners is less well established. The aim of this study was to assess whether the TR spectral Doppler ...

Purpose Microperimetry is used as an endpoint in type 2 macular telangiectasia (mactel) trials. The change required for defining disease progression depends on measurement error. We determined the threshold of test-retest variability (TRV) of microperimetry in mactel. Methods A prospective study was done of 24 patients with stable mactel enrolled in a tertiary eye clinic. Each patient underwe...

Isoprenoid biosynthesis in plant plastids occurs via the 1-deoxy-d-xylulose 5-phosphate (DXP) pathway. We used tobacco rattle virus (TRV) to posttranscriptionally silence the expression of the last two enzymes of this pathway, the IspG-encoded (E)-4-hydroxy-3-methylbut-2-enyl diphosphate synthase (HDS) and the IspH-encoded isopentenyl/dimethylallyl diphosphate synthase (IDDS), as well as isopen...

Bu çalışmada termostatik radyatör vanası (TRV) kullanımının enerji verimliliği üzerindeki etkilerinin gözlemlenebilmesi için, 98.8 m2 net kullanım alanına sahip bir dairede deneyler yapılmıştır. Deneyler, önce radyatörler üzerinde normal vanalar takılı iken yapılmış daha sonra mevcut vanalarla değiştirilerek tekrarlanmıştır. TRV’ler sayesinde her odanın sıcaklığı ayarlanan değerde sabit tutulab...
