Effects of cooking on in vitro sinigrin bioaccessibility,total phenols,antioxidant and antimutagenic activity of cauliflower (Brassica oleraceae L. var. Botrytis)

Cauliflower (Brassica oleraceae L. var. Botrytis) is a good source of bioactive compounds, such as glucosinolates, phenolic compounds and vitamins. In this study, the effects of some processes (i.e. boiling, steaming) on the sinigrin bioaccessibility as a major glucosinolate found in cruciferous vegetables after in vitro digestion, also in vitro antimutagenic activities, total phenols and total antioxidant capacities of cauliflower were determined. The sinigrin content was reduced by approximately 9.6% and 29.1% in steamed and boiled cauliflower (p > 0.05), respectively. After in vitro simulated digestion, sinigrin content was decreased by 26.4% in raw samples, increased by 29.5% and 114.7% in steamed and boiled samples, respectively. In all samples, mutagenic effect to Salmonella typhimurium TA 100 was not seen. When samples were steamed, phenol content was increased by 14.83%. After boiling total phenol content of cauliflower was decreased by 1.8%. Total antioxidant capacities (TAC) measured by 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2′-azino-bis(3 ethylbenzothiazoline-6-sulfonic acid) (ABTS) methods were increased by 47% and 39%, respectively (p < 0.05) in steamed samples and decreased by 8% and 7% with boiling, respectively (p > 0.05). TAC in raw sample of cauliflower, which was investigated in phosphomolybdenum assays, was determined as 18.7 mg ascorbic acid equivalents (AAE)/100 g. In all cases, the highest antioxidant activity was determined in the steamed samples, while the lowest antioxidant activity was in boiled samples.     

Lambl's Excrescences Involving the Pulmonary Valve Detected by Transesophageal Echocardiography

We report the first case of echocardiographically detected Lambl's excrescences on the pulmonary valve in a 72-year-old man who was referred for transesophageal echocardiography as a part of an evaluation for ischemic stroke. A total of four excrescences were noted on the arterial aspect of the pulmonary valve; two of them were on the anterior cusp, one was on the left cusp, and one was on the right cusp. The excrescence on the left cusp was the largest, measuring 5 mm in length. These valvular strands (Lambl's excrescences) represented an incidental finding and were not associated with any disease process.     

Edible safety requirements and assessment standards for agricultural genetically modified organisms.

This paper describes the background, principles, concepts and methods of framing the technical regulation for edible safety requirement and assessment of agricultural genetically modified organisms (agri-GMOs) for Shenzhen Special Economic Zone in the People's Republic of China. It provides a set of systematic criteria for edible safety requirements and the assessment process for agri-GMOs. First, focusing on the degree of risk and impact of different agri-GMOs, we developed hazard grades for toxicity, allergenicity, anti-nutrition effects, and unintended effects and standards for the impact type of genetic manipulation. Second, for assessing edible safety, we developed indexes and standards for different hazard grades of recipient organisms, for the influence of types of genetic manipulation and hazard grades of agri-GMOs. To evaluate the applicability of these criteria and their congruency with other safety assessment systems for GMOs applied by related organizations all over the world, we selected some agri-GMOs (soybean, maize, potato, capsicum and yeast) as cases to put through our new assessment system, and compared our results with the previous assessments. It turned out that the result of each of the cases was congruent with the original assessment.     

Familial dysbetalipoproteinaemia presenting with cauliflower xanthoma

Familial dysbetalipoproteinaemia (FDL) is an inherited disorder in which both cholesterol and triglycerides are elevated in the plasma, pre-disposing the people to coronary artery disease and peripheral vascular disease. The disease is mostly manifested by xanthomas, which have variable forms according to lipid amounts in the plasma of the blood. Hereby, we report a 43-year-old man with FDL, presenting with a rare form of xanthomas calling “Cauliflower xanthoma” all over the body.

Evaluation of the minimal replication time of Cauliflower mosaic virus in different hosts

Though the duration of a single round of replication is an important biological parameter, it has been determined for only few viruses. Here, this parameter was determined for Cauliflower mosaic virus (CaMV) in transfected protoplasts from different hosts: the highly susceptible Arabidopsis and turnip, and Nicotiana benthamiana, where CaMV accumulates only slowly. Four methods of differing sensitivity were employed: labelling of (1) progeny DNA and (2) capsid protein, (3) immunocapture PCR,, and (4) progeny-specific PCR. The first progeny virus was detected about 21 h after transfection. This value was confirmed by all methods, indicating that our estimate was not biased by the sensitivity of the detection method, and approximated the actual time required for one round of CaMV replication. Unexpectedly, the replication kinetics were similar in the three hosts; suggesting that slow accumulation of CaMV in Nicotiana plants is determined by non-optimal interactions in other steps of the infection cycle.     

Fibroelastic papilloma arising in a Chiari network.

The occurrence of fibroelastic papilloma arising in a Chiari network in an 85-year-old man is described. Occurrence of this tumor in this location has not been previously reported, and should be added to the differential diagnosis of intracardiac masses arising in the right atrium.
