Validation of Loop-Mediated Isothermal Amplification (LAMP) Field Tool for Rapid and Sensitive Diagnosis of Contagious Agalactia in Small Ruminants
Simple Summary Contagious agalactia (CA) is an infectious disease of small ruminants endemic in the Mediterranean countries, causing significant socioeconomic impacts predominantly on small-scale farmers who still subsist on marginal lands. Mycoplasma agalactiae is historically considered the principal etiological agent of CA, especially in sheep. Clinical signs are characterised by mastitis, arthritis, keratoconjunctivitis and occasionally, abortion. Rapid, accurate and cost-effective field tests are urgently needed for effective control of M. agalactiae mastitis. Our study illustrated the validation of a Loop-Mediated Isothermal Amplification (LAMP) test for the detection of M. agalactiae…
Cigarette smoke affects the onco-suppressor DAB2IP expression in bronchial epithelial cells of COPD patients
AbstractCigarette smoke is a risk factor for COPD and lung cancer. In cancer, epigenetic modifications affect the expression of Enhancer of Zester Homolog 2 (EZH2), and silenced disabled homolog 2 interacting protein gene (DAB2IP) (onco-suppressor gene) by Histone H3 tri-methylation in lysine 27 (H3K27me3). In“ex vivo”studies, we assessed EZH2, H3K27me3 and DAB2IP immunoreactivity in bronchial epithelial cells from COPD patients (smokers, ex-smokers), Smoker and control subjects. In“in vitro” experiments we studied the effect of cigarette smoke extract (CSE) on EZH2/H3K27me3/DAB2IP expression, apoptosis, invasiveness, and vimentin expression in 16HBE, primary cells, and lung cancer cell lin…
COVID-19 and non–COVID-19 pneumonia: a comparison
Abstract Background The COVID-19 pandemic has caused the relocation of huge financial resources to departments dedicated to infected patients, at the expense of those suffering from other pathologies. Aim To compare clinical features and outcomes in COVID-19 pneumonia and non-COVID-19 pneumonia patients. Patients and methods 53 patients (35 males, mean age 61.5 years) with COVID-19 pneumonia and 50 patients (32 males, mean age 72.7 years) with non-COVID-19 pneumonia, consecutively admitted between March and May 2020 were included. Clinical, laboratory and radiological data at admission were analyzed. Duration of hospitalization and mortality rates were evaluated. Results Among the non-COVID…
Effects of aging on sensation of dyspnea and health-related quality of life in elderly asthmatics
BACKGROUND AND AIMS: As the awareness of sensory stimuli is often impaired in older subjects, it has been hypothesized that the aging process may influence the perception of dyspnea. This study aimed at evaluating the aging-related difference in perception of spontaneously occurring dyspnea in adult asthmatics and at whether any such aging-related differences have an effect on the health-related quality of life (HRQOL). METHODS: 18 elderly asthmatics (EA) aged >65 years and 20 young asthmatics (YA) (age range 16-44 years) were recruited. In all subjects, 12-month asthma symptom score and respiratory function were recorded. Dyspnea was measured at rest by the Visual Analog Scale (VAS) and HR…
Cigarette smoke alters the EZH2/DAB2IP expression in bronchial epithelial cells. A risk factor for lung cancer in COPD patients
Cigarette smoke is an environmental risk factor for COPD and Lung cancer, leading causes of morbidity and mortality worldwide. In cancer, enhancer of zeste homolog 2 (EZH2) silenced disabled homolog 2 interacting protein gene (DAB2IP) (tumor-suppressor gene) bytri-methylation of lysine 27 on histone H3 (H3K27me3). We studied EZH2 and DAB2IP expression in airway epithelial cells from COPD patients and their potential involvement in the progression of COPD toward lung cancer. We assessed EZH2 and DAB2IPimmunoreactivity in bronchial epithelial cells from surgical specimens of COPD patients and healthy control subjects (HC) by immunohistochemistry. Bronchial epithelial cell line (16HBE), primar…
