Plants can be exposed to ionising radiation not only in Space but also on Earth, due specific technological applications or after nuclear disasters. The response of plants depends quality/quantity and/or plant characteristics. In this paper, we analyse some growth traits, leaf anatomy, and ecophysiological features Solanum lycopersicum L. “Microtom” grown from seeds irradiated with increasing doses X-rays (0.3, 10, 20, 50, 100 Gy). Both juvenile compound leaves developed control were...
Abstract Background: Casein phosphopeptides (CPPs) are phosphorylated casein‐derived peptides produced synthetically by proteolytic digestion of α s1 ‐, s2 ‐ and β‐casein. The anticariogenic activity CPPs is due to their ability stabilize high levels amorphous calcium phosphate (ACP) on tooth surface, preventing demineralization enhancing remineralization enamel caries. aim this study was test the in vitro natural (contained yogurt) prevent promote dental enamel. Methods: Eighty human molars...
Indoor radon concentrations were measured in dwellings of the Puglia region Southern Italy using LR-115 passive detectors. The results show that varied from 15 ± 2 to 2166 133 Bq/m³ with a geometric mean 114 and standard deviation 2.3. An analysis on factors affecting concentration such as age dwellings, floors, stories, was performed. effective dose inhabitants has been calculated found be 8.2 mSv/y. Finally, for estimation cancer risks, lifetime risk lung cases per years million have calculated.
Social isolation and exclusion are associated with poor health status premature death. A number of related factors, inadequate transportation system restrictions in individuals’ life space, have been malnutrition older adults. Since eating is a social event, can negative effect on nutrition. Cultural involvement participation interactive activities essential tools to fight isolation, they counteract the detrimental effects health. To provide data supporting hypothesis that encouraging might...
PTPD1, a cytosolic non-receptor protein-tyrosine phosphatase, stimulates the Src-EGF transduction pathway. Localization of PTPD1 at actin cytoskeleton and adhesion sites is required for cell scattering migration. Here, we show that during EGF stimulation, rapidly recruited to endocytic vesicles containing receptor. Endosomal localization mediated by interaction with KIF16B, an endosomal kinesin modulates receptor recycling plasma membrane. Silencing promotes degradation inhibits downstream...
Background: Radon and its decay products are the main source of natural ionizing radiation they represent major contributor to internal dose human life. The aim this study was assess a potential relationship between indoor radon exposure incidence lung cancer worldwide.Methods: A systematic literature search carried out in PubMed, Web Science, Google Scholar identify relevant studies published English conducted last 15 years until January 2016. Summary relative risks (RR) corresponding 95%...
This study focuses on the indoor radon gas monitoring in 30 residences Campania to evaluate seasonal variability. Approximately 570 CR‐39 solid‐state detectors were employed. Measurements taken monthly, quarterly, semiannually, and annually, starting October 2022 ending September 2023. The variability was assessed using Gini coefficient, with quarterly semiannual values being comparable at 6% 7%, respectively, while monthly measurements exhibited a higher 13%. conducted accordance UNI ISO...
Abstract We performed a case‐control study in Lazio, region central Italy characterized by high levels of indoor radon, Mediterranean climate and diet. Cases (384) controls (404) aged 35–90 years were recruited the hospital. Detailed information regarding smoking, diet other risk factors collected direct interview. Residential history during 30‐year period ending 5 before enrolment was ascertained. In each dwelling, radon detectors placed both main bedroom living room for 2 consecutive...
Guidelines recommend upper endoscopic screening of cirrhotic patients for gastroesophageal varices. Cirrhosis is not always distinguishable from chronic hepatitis.To identify low-risk who can be spared endoscopy irrespective a diagnosis cirrhosis.We evaluated 13 nonendoscopic variables as predictors esophagogastric varices in 254 with hepatitis B or C-related liver disease underwent endoscopy.Any size occurred 30.3% (77/254), and large 12.2% (31/254). Age >50 years [odds ratio (OR): 11.29;...
<i>Objectives:</i> Protein tyrosine phosphatases are key regulators of intracellular signaling that contribute to determining cancer cell growth, which thus makes them attractive targets for therapeutic and diagnostic agents. SHP-1 phosphotyrosine phosphatase is rarely expressed in epithelial tumor cells, but expression has been found several breast lines tumors. To determine the potential significance as a prognostic marker clinical setting, we examined protein...
In this study, the indoor radon concentrations have been measured in 93 dwellings of Penisola Sorrentina, using LR115 detectors. The detectors were placed bedrooms and living rooms for two consecutive semesters starting from December 2010 to 2011. annual average vary 25 722 Bq m(-3), with a mean value 132 ± 114 m(-3). Correlation between measurements same building characteristics was also studied. Based on obtained results, effective dose 2.4 mSv y(-1) received by inhabitants estimated.
Radon is a major source of ionizing radiation exposure for the general population. It known that to radon risk factor onset lung cancer. In this study, results survey conducted in all districts Public Healthcare Italy, are reported. Measurements indoor were performed using nuclear track detectors, CR-39. The entire was according well-established quality assurance program. annual effective dose and excess lifetime cancer also calculated. Results show concentrations varied from 7 ± 1 Bq/m3...
This work concerns continuous monitoring of radon and thoron specific activity in soil gas within the framework identifying possible anomalies. It is based on analysis a medium-term data record obtained from an area geophysical interest. The RaMonA spectrometric system also used to measure climatic parameters alpha spectra performed better determine lines intensity. Since emission influenced by meteorological parameters, it mandatory differentiate changes due deep phenomena. Different...
The aim of the paper is to give information about radon concentration in air and water 16 thermal spas Isle Ischia assess corresponding mean effective dose for workers. Measurements were carried out by means Electret Passive Environmental Radon Monitor (E-PERM) devices long-term configuration, while activity was measured using same detectors short-term configuration. In each plant, several kinds rooms different uses (office, muddy room, massage relax aerosol, mud pit medical treatment room)...
Humans are mostly exposed to ionizing radiation through radon and its decay products. The results of indoor measurements in 39 kindergartens primary schools the Campania region southern Italy presented this paper. survey was carried out with CR-39 solid-state nuclear track detectors (SSNTDs). Radon concentrations were measured ranged from 11 1416 Bq/m3, a geometric mean 77 Bq/m3 standard deviation 2. findings revealed that 70% measures below WHO recommended level 100 97 percent 300 set by...
Human prostate cancer cells were evaluated for growth after photodynamic therapy, radiotherapy, and combined treatment. Indocyanine green was tested as a photosensitizer radiosensitizer. Two human cell lines used: PC-3 derived from carcinoma, EPN normal tissue. The light source used the photoactivation experiments diode laser peaked at 805 nm. dose incident on 108 J/cm(2). Ionizing radiation produced by linear accelerator, 2, 4 6 Gy. Cytotoxicity measuring colony forming ability of cells....
