Bran oil and gamma-oryzanol in the treatment of hyperlipoproteinemias and other conditions.
No full textDiet is the first (and sometimes the only) therapeutic approach to hyperlipoproteinaemias. Rice bran oil and its main components (unsaturated fatty acids, triterpene alcohols, phytosterols, tocotrienols, alpha-tocopherol) have demonstrated an ability to improve the plasma lipid pattern of rodents, rabbits, non-human primates and humans, reducing total plasma cholesterol and triglyceride concentration and increasing the high density lipoprotein cholesterol level. Other potential properties of rice bran oil and gamma-oryzanol, studied both in vitro and in animal models, include modulation of pituitary secretion, inhibition of gastric acid secretion, antioxidant action and inhibition of platelet aggregation. This paper reviews the available data on the pharmacology and toxicology of rice bran oil and its main components with particular attention to those studies relating to plasma lipid altering effects
What do herbalists suggest to diabetic patients in order to improve glycemic control? Evaluation of scientific evidence and potential risks
No full textIn the course of 12 continuing education seminars given in different regions of Italy in 2001, we distributed a questionnaire to all the attending herbalists asking information about the herbal remedy and dietary supplement they mainly recommended to subjects who required a "natural" treatment to control glycemia. We distributed 720 questionnaires and we received 685 completed ones. We have compiled a short review on the efficacy and safety of the 10 most frequently advised products for each category. The 10 more frequently suggested herbal remedies were gymnema, psyllium, fenugreek, bilberry, garlic, Chinese ginseng, dandelion, burdock, prickly pear cactus, and bitter melon. The 10 most frequently recommended dietary supplements were biotin, vanadium, chromium, vitamin B6, vitamin C, vitamin E, zinc, selenium, alpha-lipoic acid, and fructooligosaccharides. The majority of the products recommended by Italian herbalists may be efficacious in reducing glycemia. If a diabetic patient is already assuming products that even slightly reduce glycemia, we risk to underestimate the level of glucose intolerance, while if the patient stops the complementary treatment after initiating pharmaceutical therapy, in the subsequent visit we may underestimate the effect of our prescription. Therefore, if doctors are to have a role in gate-keeping or advising patients about complementary and alternative medicine, they need to be familiar with this type of medicine. If they choose otherwise, then the provision of complementary and alternative medicine will continue to be patchy and largely outside the conventional care framework, perhaps through a growing network of parallel care providers involving a large number of non-medically qualified practitioners, who patients will continue to access directly
The Contribution of Digital Sociology to the Investigation of Air Pollution
No full textAir pollution and its implications for quality of life and human health are an important issues in industrialised and ur-banised countries. In recent years, there has been an increase in interest in alternative and supplementary air quality analysis methods which utilise techniques involving technologies developed during the Internet 2.0. In particular, the spread of mobile devices and the social media have contributed to the emergence of the new approaches discussed in this paper: People as Sensors, Citizen Science, and Collective Sensing. People as Sensors refers to the involvement of humans in the measurement phenomena and collection of data through mobile devices when used as sensing instru-ments. Citizen Science is a form of participatory sensing based on projects which enable citizens to act as agents of change. Collective Sensing is based on new research techniques which analyse the user-generated content published through social media platforms to explore concerns, opinions, alert messages, reactive behaviour and other aspects of human life. The common denominator of these approaches is the engagement of citizen as prosumer.
After the conceptualisation of and comparison between the three different approaches, several examples of applications in the air pollution field will follow. The conclusion will discuss the pros and cos of these developments in investigation

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

No full textA suggestion for Familial Hypercholesterolemia (FH) heterozygosity clinical diagnosis based on an epidemiological observation in a large Italian population
No full textWe selected 247 subjects from 29 large familial hypercholesterolemia (FH) kindreds from 550 probable FH subjects in Emilia Romagna (Italy) on the basis of LDL-cholesterol plasmatic levels and family trees, in order to define the best diagnostic criteria for heterozygous patients. Familial hypercholesterolemia is a monogenic disease of cholesterol metabolism inherited as an autosomal dominant trait and characterised by early cardiovascular disease. A low xanthomas and xanthelasmas prevalence was found (8.6%); coronary heart disease (CHD) death occurs very frequently in heterozygous males (72% of all deaths; mean age at death 52 years), while in females the primary cause of death was thrombotic stroke (55%; mean age 69 years). Total cholesterol (TC) mean values were 389.8 (m) and 373.3 mg/dl (f) for FH trait carriers, and 223.3 (m) and 228.8 (f) for healthy relatives. No age-related change in TC was found in heterozygotes, while unaffected relatives of FH families showed mean TC and LDL-C values, and a TC frequency distribution and a TC age-related increasing trend similar to the expected values for the Italian population. The TC frequency distribution curve appeared bimodal, with a mid-point between heterozygous and homozygous FH modal values of 280 mg/dl. To identify the FH patients, the final FH heterozygosity risk was evaluated in an unselected free-living population (from 0.07 to 0.8%, respectively, for TC between 265-274 and 295-304 mg/dl) and in hypercholesterolemic families (31 to 83%, and the same TC classes). Our conclusion is that the clinical picture is rarely pathognomonic, while the FH heterozygosity final risk evaluation and the 280 mg/dl cut-off point can be used to guide the practical clinical diagnosis and to select the patients destined for B-E receptor activity evaluation
