Quality and shelf-life of minimally processed cauliflower
2018
Il cavolfiore è stato descritto come un ortaggio con un alto valore nutrizionale grazie al suo alto contenuto di vitamine, antiossidanti e composti anti-cancerogeni. Le infiorescenze di cavolfiore vengono raccolte mentre sono totalmente immature, il che implica gravi cambiamenti nello stato dei nutrienti, dell'acqua e degli ormoni. La raccolta e la successiva lavorazione possono causare gravi stress determinando la comparsa di sintomi di senescenza accelerata. Sono stati studiati gli effetti della lavorazione e della conservazione a freddo del cavolfiore trasformato minimamente. Gli ornamenti sono stati trattati con antiossidanti prima della conservazione in sacchi di PE a 4 ° C per 21 gior…
Effect of low SO2 postharvest treatment on quality parameters of ‘Italia’ table grape during prolonged cold storage
2018
Table grape is a non-climacteric fruit with a low rate of physiological activity, very sensitive to water loss and fungal infection (Botrytis cinerea) during postharvest handling and cold storage. Gray mold is the most aggressive postharvest disease, because of its ability to develop at low temperatures, for that reason, it is standard practice to fumigate with sulfur dioxide (SO2) immediately after packing. ‘Italia’ table grape boxes were stored at 2°C for 4 months in a storage room with low concentrations of SO2 (0.20%) to extend their postharvest shelf life. Every 15 days, a sample of ‘Italia’ table grapes boxes was moved to 20°C for 3 days for the shelf life simulation. During storage, …
Reproducibility of Skin Temperature Response after Cold Stress Test Using the Game Ready System: Preliminary Study
2021
The objective of this preliminary study was to determine the reproducibility of lower limbs skin temperature after cold stress test using the Game Ready system. Skin temperature of fourteen participants was measured before and after cold stress test using the Game Ready system and it was repeated the protocol in four times: at 9:00, at 11:00, at 19:00, and at 9:00 h of the posterior day. To assess skin temperature recovery after cold stress test, a logarithmic equation for each region was calculated, and constant (β0) and slope (β1) coefficients were obtained. Intraclass correlation coefficient (ICC), standard error (SE), and within-subject coefficient of variation (CV) were determined. No …
Chronic spontaneous urticaria or autoinflammatory disease? The therapeutic effect of omalizumab in a pediatric patient.
2018
Chronic spontaneous urticaria (CSU) is a clinical condition characterized by spontaneous or inducible recurrent wheals. This condition may significantly affect quality of life of patients and of their families. Etiology is not identified in 25-85% of cases that are indicated as 'idiopathic', because all diagnostic tests are negative. Autoimmune processes may be present in 30-50% of patients, although a definite etiological diagnosis is seldom possible. Some patients, in fact, have autoantibodies against the high-affinity IgE receptor FceR1 or IgE. These patients show an increased incidence of anti-thyroid autoantibodies and represent 30-50% of the patients designated as having CSU. Familial…
Pancreatic islets from non-heart beating donor pig: Two-layer preservation method in an in vitro porcine model
2011
Purpose Pancreata from non-heart beating donors could represent an unlimited source of islets if their cell viability can be efficiently preserved during the time necessary to process the organs by the use of a better solution of preservation compared to the classic University of Wisconsin solution. The aim of this study was to determine whether it is possible to obtain functioning “alive islets” from non-heart-beating donors by comparing, on a porcine model, the classic “UW ice-store” method with a two-layer cold storage method (TLM) using oxygenated Perfluorocarbons (PFC) and UW. Methods Whole pancreata were harvested from 20 NHBDs female pigs with similar characteristics and preserved fo…
Is there a role for antileukotrienes in urticaria?
2006
In vitro and in vivo clinical and experimental data have suggested that leukotrienes play a key role in inflammatory reactions of the skin. Antileukotriene drugs, i.e. leukotriene receptor antagonists and synthesis inhibitors, are a new class of anti-inflammatory drugs that have shown clinical efficacy in the management of asthma. We searched the MedLine database and carried out a manual search on journals specializing in allergy and dermatology for the use of antileukotriene drugs in urticaria. Montelukast might be effective in chronic urticaria associated with aspirin or food additive hypersensitivity or with autoreactivity to intradermal serum injection when taken with an antihistamine b…
Avoidant coping, verbal-autonomic response dissociation and pain tolerance
2006
Higher autonomic reactivity relative to self-reported discomfort, often found in repressors and avoidant copers might be associated with a diminished perception of bodily symptoms. This study aimed at relating such so-called verbal-autonomic response dissociation to pain tolerance. Eighty-five volunteers underwent a public speaking task and a cold pressor test. Heart rate and negative affect in response to the speech, and pain ratings and facial muscle responses for the cold pressor were obtained. A dissociation score was calculated for each individual in response to speech, thereby subtracting standardized changes in negative affect from standardized changes in heart rate. Response dissoci…
Metabolism of rat liver cells during incubation in cold UW solution
1997
Simple cold storage of livers for transplantation activates glycolysis due to lack of oxygen. Energy derived from glycolysis may be critical for cell survival and liver cell death may occur once glycolysis is inhibited in the liver due to accumulation of end products or lack of substrates (glycogen). The relationship between cell death (lactate dehydrogenase, LDH release), anaerobic glycolysis (lactate production), and glycogen content of liver tissue was studied during cold incubation of liver slices in UW solution. Rat livers slices from male Sprague Dawley rats were incubated at 4 degrees C in UW solution, with continuous gentle shaking, under conditions of chemical hypoxia (KCN, 5 mM). …
Increased pain and neurogenic inflammation in mice deficient of neutral endopeptidase
2009
The complex regional pain syndrome (CRPS) is characterized by enhanced neurogenic inflammation, mediated by neuropeptides. Neutral endopeptidase (NEP) is a key enzyme in neuropeptide catabolism. We used NEP knock out (ko) mice to investigate whether NEP deficiency leads to increased pain behavior and signs of neurogenic inflammation after soft tissue trauma with and without nerve injury. After chronic constriction injury (CCI) of the right sciatic nerve, NEP ko mice were more sensitive to heat, to mechanical stimuli, and to cold than wild type mice. Tissue injury without nerve injury produced no differences between genotypes. After CCI, NEP ko mice showed increased hind paw edema but lower …
Contrasting patterns of temperature related mortality and hospitalization by cardiovascular and respiratory diseases in 52 Spanish cities.
2020
Climate change is a severe public health challenge. Understanding to what extent fatal and non-fatal consequences of specific diseases are associated with temperature may help to improve the effectiveness of preventive public health efforts. This study examines the effects of temperature on deaths and hospital admissions by cardiovascular and respiratory diseases, empathizing the difference between mortality and morbidity.
