Abstract: The methanolic crude extract of the bark and seed of Entada phaseoloides (L.) Merr. and its different organic soluble partitionates were screened for antioxidant, cytotoxic, membrane stabilizing andantimicrobial activities. The crude extract and carbon tetrachloride and aqueous soluble fractionsof both bark and seed showed higher level of total phenolic content (TPC, 245.59, 240.22, 240.03 & 117.0 mg of GAE/gm of dried extract). In the DPPH assay, the crude extract of bark and its chloroform and aqueous soluble fractions demonstrated strong antioxidant property with the IC50 of 3.24, 1.55 and 3.6 μg/ml, respectively whereas all the fractions of seed extract revealed mild antioxidant activity. The petroleum ether soluble fractionof both seed and bark exhibited significant cytotoxicity (LC50 = 1.54 & 5.4 mg/ml) which confers the presence of bioactive metabolites in this plant. On the other hand, the crude extract of seed and petroleum ether soluble fraction of bark inhibited the hemolysis of RBC of rat’s blood by 78.89 and 57.43%, respectively as compared to 84.44% exerted by acetyl salicylic acid (0.10 mg/ml). In antimicrobial screening, the carbon tetrachloride soluble fraction of bark showed significant antimicrobial activity against Staphylococcus aureus (zone of inhibition = 17.0 mm) with MIC and MBC values of 7.81 mg/ml and 125 mg/ml, respectively.

Keywords: Antimicrobial, minimum inhibitory concentration (MIC), minimum bactericidal concentration (MBC).

Abstract: The aims of this study were to develop and validate the short food frequency questionnaire (sFFQ) to assess calcium intake from food in Thais person for use in clinical practice or community pharmacy.
Data collection was performed during November 2009 to January 2010. The sFFQ consisted of 33 item of food. The frequency of food intake in sFFQ food list was interviewed by investigator. Seven day after subject were interviewed by sFFQ, subjects were asked to fill out the Three Day Dietary Record (3DR) for 3 day. Daily calcium intake assessed by both methods was calculated by using INMUCAL software, which was developed by the Institute of Nutrition, Mahidol University.
The 131 subjects who completed sFFQ and 3DR had mean age of 24.4 years, 71.3% were female. The mean daily calcium intake assessed by sFFQ and 3DR were 692.0 + 524.9 mg and 477.4 + 261.9 mg, respectively. The mean daily calcium intakes assessed by sFFQ were significantly higher than 3DR (p < 0.05). The Spearman’s correlation coefficient between calcium intakes assessed by the two methods was 0.18 (p <0.05).
In conclusion, the newly developed sFFQ was a suitable tool for the determination of calcium intakes in Thais adults. The next step in assessing the validity of this sFFQ will be its use in clinical setting such as community pharmacy or out-patient clinic.

Keywords: Calcium, short food frequency questionnaire, intake, dietary record.

Abstract: Nutritional genomics describes the biological interactions between genes and diet, their effects on the metabolism, and susceptibility to develop diseases. This approach covers both nutrigenomics that explores the effects of nutrients on the genome; and nutrigenetics that explores the effects of genetic polymorphisms on diet/disease interactions. These interactions vary because individuals have unique combinations of common genetic polymorphisms that are differentially affected by diet. Diseases causality is associated to certain genetic polymorphisms providing predictive biomarkers for diagnostic accuracy. Specific nutrient can modify the expression of genes through the interaction with receptors that activate the transcription of target genes and affect signal pathways. Nutritional genomics is aimed to prevent onset of diseases and maintain human health, identify individuals who are responders and can benefit from specific dietary interventions, and identify how genetic variation affects human nutritional requirements. Nutritional genomics has many potential therapeutic and preventive applications: in individuals with a genetic predisposition to complex diseases including cancer, diabetes and cardiovascular disorders; in those already suffering from these diseases; and in those with memory impairment during aging. This review describes nutritional facts linked to genomic aspects to manage multigenic diseases. It presents some notable example of nutrients with proven modulating gene activity, and the role of nutrition associated with nutritional genomics. Hereafter we briefly review the health-promoting properties of two well-known edible plants, i.e. dandelion and artichoke whose presence in the diet could simultaneously exert positive influence on molecular genomic mechanisms related to risk factors for chronic diseases.

Keywords: Food, gene-nutrient interaction, dandelion, artichoke, phytochemicals, minerals.

Abstract:Pioglitazone (pio) has been used as an effective hypoglycemic drug in medicine, however, the effects and mechanisms of pio on lipid metabolic disorder are still largely unknown. To explore the effects of pio on serum and liver lipid level and antioxidant ability of mice with lipid metabolic disorder, KKAy mice were treated with pio for 12 weeks and their lipid and antioxidant indices were compared to those of KKAy mice without pio treatment. C57BL/6J mice were used as control animals. The results show that pio treatment reduces serum and liver TG, elevates serum HDL-C level, increases serum and liver SOD activity, attenuates serum MDA content, ameliorates liver steatosis, induces liver PPARγ expression and enhances AMPKα phosphorylation level. In conclusion, the results indicate that pio could regulate blood lipid level, reduce liver lipid deposition and enhance antioxidant capacity of mice with lipid metabolic disorder, which is possibly through increasing AMPKα phosphorylation.

Abstract: Neotorularia aculeolata belongs to the family Cruciferae that has several uses in the Egyptian folk medicine for many years. Nothing could be traced about the chemical composition of the plant. Extraction, isolation and purification of the air-dried plant material using different chromatographic techniques (PC, TLC & CC) provided seven flavonoids. Identification of the isolated compounds using different chemical and physical techniques (UV, 1H-NMR and C 13 NMR spectroscopy) allowed to characterize these compounds as kaempferol, kaempferol-7-O-rhamnoglucoside {Kaempferol-7-neohesperidoside}, quercetin, rutin, quercetin-3-O- β-D-glucoside-7-O-α-L-rhamnoside-3`-methylether, quercetin-3,7-di-O-α-L-rhamnoside-3`-methylether and myricetin.

Abstract: The strong inverse relationship between high density lipoproteins-cholesterol (HDL-C) levels and cardiovascular disease (CVD) has aroused a strong interest in the research of lifestyle and pharmacological agents capable of elevating plasma HDL levels. HDL is essential in reverse cholesterol transport (RCT), thus its anti-atherogenic function. However, torcetrapib, a compound that increases plasma HDL-C levels, was unexpectedly associated with an increased cardiovascular mortality. The findings led to consider that HDL functionality and quality might be more relevant to CVD than the total circulating HDL quantity itself. Adherence to the Mediterranean diet is known to be associated with increased HDL-C and decreased risk of CVD. However, the mechanism by which this happens has been yet poorly investigated and the effect of nutrition on HDL functionality and quality needs further attention.

Keywords: HDL functionality, HDL quality, nutrition, cardiovascular disease, reverse cholesterol transport (RCT), ATP-binding cassette transporters.

Abstract: We have presented the first example of the synthesis of macromonomers by mechanochemical reaction of polymethylmethacrylate (PMMA) and maleic anhydride (MA). The mechanochemical reaction of PMMA and MA was carried out by vibratory ball milling under anaerobic condition. The ESR spectrum of the fractured sample of PMMA and MA showed a broad singlet, which was apparently different from the spectrum of PMMA mechanoradical. Therefore, PMMA mechanoradical would react with MA. We underwent the UV-labeling of the fractured samples of PMMA and MA to confirm the formation of macromonomers. The gel permeation chromatograms of UV-labeled compounds derived from this fractured sample showed a broad peak in a polymer region with refractive index detector and UV detector, which indicates that macromonomers bounding MA would be produced. This method seems to be applicable for a wide variety of polymers to synthesize macromonomers possessing MA.

Keywords: Mechanoradical, ESR, vibratory milling, maleic anhydride.

Abstract: Many people in the world suffer from fibromyalgia (FM), a rheumatic disease of unknown ethiopathophysiology and without an effective treatment. Patients do not have a good quality of life and cannot maintain normal daily activity. FM commonly occurs with other diseases, some of them, like irritable bowel syndrome, obesity, or some food allergies or intolerances, are related or affected by diet. Non-scientific information addressed to patients regarding the benefits of nutrition is widely available, and they are used to trying non-evidenced strategies. The aim of this paper is to make a first reflection on the relevance of diet related diseases in FM patients, to reinforce investigation in this field and highlight the importance of health professional advice regarding diets and use of food supplements. An internet based survey was prepared and offered to answer in a specific FM website. Patients were asked about hypertension, hypercholesterolemia, hypertriglyceridemia, irritable bowel syndrome, food allergies and intolerances, and overweight or obesity. Ninety seven persons answered to the survey, two men and ninety five women. Irritable bowel syndrome and excess weight (overweight and obesity) were the most reported diet-related diseases. In the third position were food allergies or intolerances, and in the fourth hypertension. Diet-related diseases are frequent in FM patients, who even sometimes suffer more than two. Therefore, more investigation and dietary advice seems to be necessary to these patients to improve their diets, taking into account FM but also other pathologies, to keep an optimum nutritional status and maintain a normal weight.
