Influence of brassica sprouts on short chain fatty acids concentration in stools of rats with thyroid dysfunction

The aim of the study was to investigate the influence of kohlrabi and broccoli sprouts added to the diet on the concentrations of short-chain fatty acids in feces samples of rats with thyroid dysfunction. Two models of hypothyroidism were used. The first one was based on the diet with iodine deficiency and the second by sulfadimethoxine addition to the animal drinking water. In most cases, the concentrations of acetic acid, propanoic acid and butanoic acid in stool samples obtained from rats with thyroid dysfunction were insignificantly lower than found in the control group. Moreover, almost in all cases the diet enriched with brassica sprouts insignificantly increased the concentration of fatty acids in investigated material. A significant positive correlation between concentrations of butanoic and acetic acids was found in different groups of rats. In conclusion, the addition of broccoli or kohlrabi sprouts in ratís diet may slightly alleviate the decline of concentrations of some fatty acids in the stool of animals with thyroid dysfunction. Long term effects of this phenomenon should be evaluated in future studies

Selenium supplementation of amaranth sprouts influences betacyanin content and improves anti-inflammatory properties via NFκB in murine RAW 264.7 macrophages

Abstract Sprouts contain potent compounds which while influencing crucial transduction pathways in cell reveal anti-inflammatory and anticancer activities. In this study, we report the biological activity for seeds and colourful sprouts of four types of edible amaranth, as amaranth has recently attracted interest due to its appreciable nutritional value. MTT assay conducted for the amaranth seeds and sprouts did not show any adverse effect on the viability of murine RAW 264.7 cells. As amaranth accumulates selenium, the sprouts were supple-mented with this trace element (10 mg/L; 15 mg/L Se as so-dium selenite) while growing. Selenium concentration in sprouts was observed to be significantly correlated with betacyanins content of the tested species. The amounts of Se and betacyanins in sprouts varied for various Amaranth spe-cies. In the present study, Amaranthus cruentus sprouts with the highest betacyanins (19.30 ± 0.57–28.85 ± 2.23 mg of amaranthin/100 g of fresh weight) and high total selenium (22.51 ± 1.57–1044.75 ± 73.08 μg/L in methanol extracts) content prevented NFκB translocation to the cell nucleus and subsequently exerted an anti-inflammatory effect by sig-nificant decreasing inflammatory interleukin 6 production (587.3 ± 34.2–710.0 ± 88.1 pg/mL) in the cell culture of acti-vated RAW 264.7 macrophages (vs LPS control 1520 ± 114 pg/mL)

Animals in iodine deficiency or sulfadimethoxine models of thyroid damage are differently affected by the consumption of brassica sprouts

The study was primarily aimed at investigating the effect of brassica sprout consumption, namely rutabaga (Brassica napus L. var. napobrassica) sprouts (R) generally recognized as antithyroid agent due to its goitrogenic substance content, on hematological, biochemical, and immunological parameters in rats. Sprouts were tested alone and in a combination with other antithyroid factors, such as iodine deficiency (RDI) and sulfadimethoxine (RS). The expression of the heme oxygenase-1 (HO-1) gene in the thyroid as a stress-inducible protein was determined. The thermographic analysis was also estimated. The intake of rutabaga sprouts by healthy rats did not reveal any significant, harmful effect on the thyroid function. Both body temperature and expression of HO-1 remained unchanged in response to the consumed sprouts. In animals with hypothyroidism, rutabaga sprouts enhanced the negative effect of iodine deficiency or sulfadimethoxine ingestion on the organism by increasing the WBC (RDI), TNF-α (RS), creatinine (RS), and triglyceride (RDI and RS) levels, as well as decreasing PLT (RS) level. Moreover, rutabaga sprout consumption by rats with iodine deficiency and sulfadimethoxine decreased their body temperature. Additionally, the concomitant administration of sprouts and iodine depletion significantly reduced the expression of HO-1 in the thyroid. The results may prove useful in confirming rutabaga sprout consumption to be safe, though the seeds of this vegetable provide a well-known antithyroid agent. Our results have shown that rutabaga sprout consumption may be also a factor that enhances the negative clinical features only when combined with iodine deficiency and sulfadimethoxine ingestion

Improvement of physical capacity in patients undergoing transcatheter closure of atrial septal defects

Introduction: Atrial septal defect (ASD) is the most common congenital cardiac anomaly diagnosed in adults. It often remains asymptomatic until the fourth or fifth decade of life. Significant left-to-right interatrial shunting is associated with the risk of heart failure, pulmonary hypertension and atrial fibrillation. Percutaneous ASD closure is a recognized method of treatment. Aim: To evaluate the clinical outcomes and physical capacity in patients undergoing transcatheter closure of ostium secundum ASD. Material and methods: One hundred and twenty adult patients (75 females and 45 males) with a mean age of 43.1 ±13.3 (17–78) years who underwent transcatheter device closure of ostium secundum ASD were analyzed. Clinical evaluation and transthoracic color Doppler echocardiographic study were repeated in all patients before as well as 1 and 24 months after the procedure. To assess the physical capacity symptom-limited treadmill exercise tests with respiratory gas-exchange analysis were performed in all patients before the procedure and after 24 months of follow-up. Results: The devices were successfully implanted in all patients. During 24 months of follow-up all patients showed significant clinical and spiroergometric improvement of exercise capacity, and a significant decrease of right heart chamber overload features on echocardiography. Conclusions: Transcatheter closure of ASD in patients with significant shunt resulted in significant clinical and hemodynamic improvement regardless of the baseline functional class
