Timing and Patient Position During Cuff Blood Pressure Measurement Affect Myocardial Work Parameters Measured by Echocardiography.

Background: Although cuff blood pressure measurement is a critical parameter to calculate myocardial work noninvasively, there is no recommendation about when and how to measure it. Accordingly, we sought to evaluate the effects of the timing during the echo study and the patient's position on the scanning bed during the cuff blood pressure measurement on myocardial work parameter calculations.

Methods: One hundred one consecutive patients (44 women, 66 ± 14 years) undergoing clinically indicated echocardiography were prospectively enrolled.

Peripheral membrane proteins modulate stress tolerance by safeguarding cellulose synthases.

Controlled primary cell wall remodeling allows plant growth under stressful conditions, but how these changes are conveyed to adjust cellulose synthesis is not understood. Here, we identify the TETRATRICOPEPTIDE THIOREDOXIN-LIKE (TTL) proteins as new members of the cellulose synthase complex (CSC) and describe their unique and hitherto unknown dynamic association with the CSC under cellulose-deficient conditions. We find that TTLs are essential for maintaining cellulose synthesis under high-salinity conditions, establishing a stress-resilient cortical microtubule array, and stabilizing CSCs at the plasma membrane.

Evolving epidemiology of HIV/AIDS in Campania region, 2011-2018: Is HIV/AIDS population in Campania different?

Objectives: Data on HIV/AIDS cases in Italy are collected using a standardised form. Regional epidemiology may vary. We described the epidemiological and clinical characteristics of newly diagnosed persons with HIV in the 'Cotugno' hospital in Naples during 2011-2018 and compared them with national data to identify similarities and differences.

Densità di popolazione e SARS-CoV-2: uno studio epidemiologico di urban health.

Despite SARS-CoV-2 transmission being a complex phenomenon, greater population density seems to be a risk factor. The aim of this study was to analyze through an epidemiologic urban health approach the relationship between population density and SARS-CoV-2 incidence using data which are comparable with regard to testing strategies. All 10,300 SARS-CoV-2 confirmed cases between October and December 2020 were included.

A primary cell wall cellulose-dependent defense mechanism against vascular pathogens revealed by time-resolved dual transcriptomics.

Background: Cell walls (CWs) are protein-rich polysaccharide matrices essential for plant growth and environmental acclimation. The CW constitutes the first physical barrier as well as a primary source of nutrients for microbes interacting with plants, such as the vascular pathogen Fusarium oxysporum (Fo). Fo colonizes roots, advancing through the plant primary CWs towards the vasculature, where it grows causing devastation in many crops.

Single-run HPLC Quantification of Plant Cell Wall Monosaccharides.

The plant cell wall is a complex network of polysaccharides and proteins that provides strength and structural integrity to plant cells, as well as playing a vital role in growth, development, and defense response. Cell wall polysaccharides can be broadly grouped into three categories: cellulose, pectins, and hemicelluloses. Dynamic interactions between polysaccharides and cell wall-associated proteins contribute to regions of flexibility and rigidity within the cell wall, allowing for remodeling when necessary during growth, environmental adaptation, or stress response activation.

In-Plate Quantitative Characterization of Arabidopsis thaliana Susceptibility to the Fungal Vascular Pathogen Fusarium oxysporum.

Root vascular pathogens are some of the world's most devastating plant pathogens. However, the methods used to determine plant susceptibility to this class of pathogen are laborious, variable, and in most cases qualitative. Here we present a rapid, simple, and robust infection assay for the characterization of Arabidopsis thaliana resistance to the fungal root pathogen Fusarium oxysporum.

Pathogen-induced pH changes regulate the growth-defense balance in plants.

Environmental adaptation of organisms relies on fast perception and response to external signals, which lead to developmental changes. Plant cell growth is strongly dependent on cell wall remodeling. However, little is known about cell wall-related sensing of biotic stimuli and the downstream mechanisms that coordinate growth and defense responses.

Regulation of cellulose synthesis in response to stress.

The cell wall is a complex polysaccharide network that provides stability and protection to the plant and is one of the first layers of biotic and abiotic stimuli perception. A controlled remodeling of the primary cell wall is essential for the plant to adapt its growth to environmental stresses. Cellulose, the main component of plant cell walls is synthesized by plasma membrane-localized cellulose synthases moving along cortical microtubule tracks.

Expanded type III effector recognition by the ZAR1 NLR protein using ZED1-related kinases.

Nucleotide-binding domain and leucine-rich repeat domain-containing (NLR) proteins are sentinels of plant immunity that monitor host proteins for perturbations induced by pathogenic effector proteins. Here we show that the Arabidopsis ZAR1 NLR protein requires the ZRK3 kinase to recognize the Pseudomonas syringae type III effector (T3E) HopF2a. These results support the hypothesis that ZAR1 associates with an expanded ZRK protein family to broaden its effector recognition spectrum.

Elevated Temperature Differentially Influences Effector-Triggered Immunity Outputs in Arabidopsis.

Pseudomonas syringae is a Gram-negative bacterium that infects multiple plant species by manipulating cellular processes via injection of type three secreted effectors (T3SEs) into host cells. Nucleotide-binding leucine-rich repeat (NLR) resistance (R) proteins recognize specific T3SEs and trigger a robust immune response, called effector-triggered immunity (ETI), which limits pathogen proliferation and is often associated with localized programmed cell death, known as the hypersensitive response (HR). In this study, we examine the influence of elevated temperature on two ETI outputs: HR and pathogen virulence suppression.

The incidence of narcolepsy in Europe: before, during, and after the influenza A(H1N1)pdm09 pandemic and vaccination campaigns.

Background: In August 2010 reports of a possible association between exposure to AS03 adjuvanted pandemic A(H1N1)pdm09 vaccine and occurrence of narcolepsy in children and adolescents emerged in Sweden and Finland. In response to this signal, the background rates of narcolepsy in Europe were assessed to rapidly provide information for signal verification.

Methods: We used a dynamic retrospective cohort study to assess the narcolepsy diagnosis rates during the period 2000-2010 using large linked automated health care databases in six countries: Denmark, Finland, Italy, the Netherlands, Sweden and the United Kingdom.

The inflammasome promotes adverse cardiac remodeling following acute myocardial infarction in the mouse.

Acute myocardial infarction (AMI) initiates an intense inflammatory response that promotes cardiac dysfunction, cell death, and ventricular remodeling. The molecular events underlying this inflammatory response, however, are incompletely understood. In experimental models of sterile inflammation, ATP released from dying cells triggers, through activation of the purinergic P2X7 receptor, the formation of the inflammasome, a multiprotein complex necessary for caspase-1 activation and amplification of the inflammatory response.

Do coxibs reduce prescription of gastroprotective agents? Results of a record linkage study.

Background: Coxibs are claimed to be cost-effective drugs and reduced prescription of gastroprotective agents is assumed to be one of their major benefits. Real life prescription of these drugs may be substantially different than that considered in pharmacoeconomic analyses or claimed by drug companies, yet. Our objective was to evaluate whether coxibs were associated with reduced prescription of gastro-protective agents (GPAs, specifically proton pump inhibitors, H2 blockers and misoprostol) compared to non selective NSAIDs.

Characteristics of Type 2 diabetic patients cared for by general practitioners either with medical nutrition therapy alone or with hypoglycaemic drugs.

The essential role of medical nutrition therapy (MNT) for people with diabetes is widely recognised, and its exclusive use is recommended in mild diabetes according to a stepwise therapeutic approach. We describe the characteristics of MNT-treated Type 2 diabetic patients (vs drugs) cared for by general practitioners (GPs) in order to check that appropriate differences did exist between the two groups, by auditing the data from our local shared-care program for diabetes. We had 16,000 diabetic patients (out of 630,000 inhabitants); 6,800 of them (42.

GPs' satisfaction with the doctor-patient encounter: findings from a community-based survey.

Objective: The aim of this study was to explore the characteristics of the doctor-patient relationship from the GP's point of view.

Methods: We performed a cross-sectional 1-day study in family practice. Thirty-three GPs volunteered to fill in a questionnaire at the end of each of 20 consecutive consultations on an index day.

Specific interactions of the telomeric protein Rap1p with nucleosomal binding sites.

The telomeres of Saccharomyces cerevisiae are structurally and functionally well characterized. Their telomeric DNA is packaged by the protein Rap1p (repressor activator protein 1). Rap1p is a multifunctional, sequence-specific, DNA-binding protein which, besides participating in the regulation of telomeres structure and length, is also involved in transcriptional regulation of genes essential for cell growth and in silencing.

[Analytical evaluation of significant chemical and physico-chemical parameters in water for human consumption].

A quality control of drinking water has been performed in hospitals and schools located in the Vomero-Area of Naples. Some chemical pollutants (iron, manganese, ammonia nitrogen, nitrite, nitrate, fluoride) as well as chemical and physical parameters (hardness, pH, electric conductivity, chloride, cations) have been periodically analyzed from Autumn 1991 to Summer 1992.

Alteration of serum tryptophan metabolism in patients suffering from senile cataract.

In vitro experimental evidence suggests tryptophan (TRP) is involved in protein modifications which could cause cataract formation in vivo. Previous studies of tryptophan plasma and serum metabolism are conflicting. In this study free and bound TRP plasma levels were measured in patients with senile cataract and in controls after an oral load of L-TRP (20 mg/kg b.
