Search for Baryonic Decays of \psi(3770) and \psi(4040)

2013

By analyzing data samples of 2.9 fb^{-1} collected at \sqrt s=3.773 GeV, 482 pb^{-1} collected at \sqrt s=4.009 GeV and 67 pb^{-1} collected at \sqrt s=3.542, 3.554, 3.561, 3.600 and 3.650 GeV with the BESIII detector at the BEPCII storage ring, we search for \psi(3770) and \psi(4040) decay to baryonic final states, including \Lambda\bar\Lambda\pi^+\pi^-, \Lambda \bar\Lambda\pi^0, \Lambda\bar\Lambda\eta, \Sigma^+ \bar\Sigma^-, \Sigma^0 \bar\Sigma^0, \Xi^-\bar\Xi^+ and \Xi^0\bar\Xi^0 decays. None are observed, and upper limits are set at the 90% confidence level.

Testing a Simplified Approach to Determine Field Saturated Soil Hydraulic Conductivity

2013

Abstract Interpreting and simulating hydrological processes need a large number of field saturated soil hydraulic conductivity, Kfs , data that should be collected with simple and rapid field experiments. A Simplified method based on a Beerkan Infiltration run (SBI method) was recently developed and tested successfully on Burundian soils. With the SBI method, a cylinder is inserted to a short depth into the soil and the infiltration time of a few small volumes of water repeatedly applied at the surface of the confined soil is measured. Calculating Kfs needs the slope of the linearized cumulative infiltration vs. time relationship and an estimate of the so called α* parameter. In this invest…

THE BIA VECTOR IN OBESITY AND DIABETES

2013

Although the assessment of body water compartments is of great diagnostic value, appropriate methods are not readily available for routinely clinical application. Bioelectrical impedance analysis (BIA) is a safe, noninvasive, rapid and highly reproducible procedure that is strongly influenced by body water and intra-/extracellular distribution. Four-hundred-fifty-six adults (224 males and 232 females) were enrolled and divided in subgroups on the basis of the presence of obesity and diabetes (type 1 and type 2). The aim of the study was to investigate if different BIA measurements in terms of resistance (R), reactance (Xc) and phase angle (PA) were associated to these conditions. Plotting t…

Correlation between BMI and the pathological features of prostate cancer at biopsy

2013

Introduction/Aim: Numerous clinical trials investigated the association between obesity and prostate cancer, but they yielded inconsistent results (1). Obesity has been found to be related to prostatic tumors at more advanced stages and higher Gleason grade when compared with normal population (2). An increased number of biopsy cores has been advocated by some Authors in obese and overweight men due to an increased difficulty and delay in cancer detection (3). The main aim of our research was to correlate Body Mass Index (BMI) with the pathological characteristics of prostate cancer at biopsy. Patients and Methods: Patients with positive prostate biopsy performed for palpable prostate nodul…

Obesity and Outcomes in COVID-19: When an Epidemic and Pandemic Collide.

2020

Obesity has reached epidemic proportions in the United States and in much of the westernized world, contributing to considerable morbidity. Several of these obesity-related morbidities are associated with greater risk for death with coronavirus disease 2019 (COVID-19). Severe acute respiratory syndrome coronavirus 2 penetrates human cells through direct binding with angiotensin-converting enzyme 2 receptors on the cell surface. Angiotensin-converting enzyme 2 expression in adipose tissue is higher than that in lung tissue, which means that adipose tissue may be vulnerable to COVID-19 infection. Obese patients also have worse outcomes with COVID-19 infection, including respiratory failure, n…

Body Mass index, family lifestyle, physical activity and eating behaviour on a sample of primary school students in a small town of western Sicily.

2012

<p><strong>Background</strong>: Obesity is actually a discernible issue in prosperous western society and is dramatically increasing in children and adolescents. Many studies indicate that obesity in childhood may become chronic disease in adulthood and, particularly, those who are severely overweight have an increased risk of death by cardiovascular disease. Understanding the determinants of life style and behavior in a person’s youth and making attempts to change children’s habits is considered a key strategy in the primary prevention of obesity. This study aims to find a correlation between Body Mass Index, (BMI), physical activity and eating behavior and to identify, e…

The effect of body mass index on chest trauma severity and prognosis.

2017

Patients with thoracic trauma constitute one third of all the trauma cases, in west Sicily were recorded 941 thoracic trauma during the period between 2006 and 2009. Sicily is one of the Italian regions with the highest rate of obesity: some studies have demonstrated that obesity is an independent risk factor for mortality in high energy blunt traumas.This study was conducted with trauma patients older than 20 years old who presented to our Department during the last five years. We only included thoracic injuries and politrauma with a thoracic involvement and a BMI25. Patients were divided into two groups: HET and LET patients.Thoracic trauma was more common in patients with a BMI25 than in…
