Tissue engineering scaffolds require a controlled pore size and interconnected pore structures to support the host tissue growth. In the present study, three dimensional （3D） hybrid scaffolds of poly lactic acid （PLA） and poly glycolic acid （PGA） were fabricated using solvent casting/particulate leaching. In this case, partially fused NaCl particles were used as porogen （200-300μ） to improve the overall porosity （≥90%） and internal texture of scaffolds. Differential scanning calorimeter （DSC） analysis of these porous scaffolds revealed a gradual reduction in glass transition temperature （Tg）（from 48°C to 42.5°C） with increase in hydrophilic PGA content. The potential applications of these scaffolds as implants were further tested for their biocompatibility and biodegradability in four simulated body fluid （SBF） types in vitro. Whereas, simulated body fluid （SBF） Type1 with the optimal amount of HCO 3 ions was found to be more appropriate and sensible for testing the bioactivity of scaffolds. Among three combinations of polymer scaffolds, sample B with a ratio of 75：25 of PLA： PGA showed greater stability in body fluids （pH 7.2） with an optimum degradation rate （9% to 12% approx）. X-ray diffractogram also confirmed a thin layer of hydroxyapatite deposition over sample B with all SBF types in vitro.

Effect of phytase superdosing, myo-inositol and available phosphorus concentrations on performance and bone mineralisation in broilers

A total of 2,376 one-day-old Ross broiler chickens were used to investigate the effect of myo-inositol(MYO) and phytase supplementation on performance and bone mineralization variables in broilers fed diets formulated to have varying concentrations of available phosphorus(P). The trial was designed as a2×2×3 factorial; with and without phytase superdosing(0 or 1,500 FTU/kg), MYO(0 or 3 g/kg), and dietary P(low, moderate or high). At 21 d, dietary phytase and MYO had no consistent benefit on bone mineralization variables. Bone ash reduced by 4.7% from the medium to low P diet(P < 0.01),with no effect of phytase supplementation. Superdosing improved bone P content by 6% in birds fed the low P diet, signifying an interaction between dietary P concentrations and phytase(P < 0.05). Dietary MYO addition resulted in a numerical reduction in bone ash and a significant reduction in bone strength(P < 0.05). At 42 d, the beneficial effect of phytase superdosing on feed intake and body weight gain was evident in the low P diet. Superdosing reduced feed conversion rate(FCR) at all P levels(P < 0.05),although this effect was more pronounced on the low P diet, suggesting that sufficient P being released from the phytase itself to re-phosphorylate MYO and hence improve FCR. The significant improvement in FCR was greater with superdosing than with MYO alone, and the combination led to no further improvement in FCR compared with superdosing alone, signifying a phytase and MYO interaction(P < 0.05). From these results, it can be estimated that MYO is providing around 30% to 35% of the total response to superdosing.

Association between Homa Index and Vascular Endothelial Dysfunction in Type 2 Diabetic Patients

Open Journal of Internal Medicine 2014年第4期4卷 123-129页

Introduction: In recent years, flow mediated dilatation (FMD) has become a popular technique in cardiovascular medicine. HOMA-IR was accepted to determine the insulin sensitivity as a valuable standard. In this study, we evaluated the association between HOMA-IR (homeostasis model assessment of insulin resistance) and vascular endothelial dysfunction, as assessed by endothelium- dependent flow-mediated dilatation (FMD) and nitroglycerin-mediated dilatation (NMD), in type 2 Diabetic (DM) patients. Material and Methods: Eighty four (84) consecutive out-patients were enrolled. HOMA-IR was calculated as fasting insulin (μU/ml) multiplied by fasting plasma glucose (FPG) (mg/dl) and divided by 405. The ultrasound method for measuring FMD and NMD has been used. Out of 84 patients, 42 patients were in control group and 42 patients were in diabetic group, which were further subdivided into two groups based on HOMA-IR > 3.0 and above was considered as Group I and HOMA IR < 3.0 and below was considered as Group II. Fasting Plasma Glucose (mmol/dl) (7.74 ± 2.56, 6.81 ± 1.9, p < 0.001) and Fasting Insulin (μU/dl) (13.26 ± 8.09, 6.65 ± 2.36, p < 0.001) were statistically significant in Group I. The baseline mean FMD in controls and cases (Group I and Group II) was 15.36 ± 9.56, 4.15 ± 2.29, 12.21 ± 6.24 (p < 0.001) respectively. By logistic regression analysis the factors which were effective on FMD percentage change (<5.5%) in Group I were BMI (p < 0.02), plasma Insulin (p < 0.04) and triglycerides (p < 0.02). There was a negative co-relation for FMD, NMD and HOMA-IR. Discussion: We conclude that increased HOMA-IR in hyperglycaemic patients is associated with severe endothelial dysfunction which is the marker of the atherosclerosis. Thus the measurement of endothelial vasomotor function which is a comprehensive analysis of atherosclerotic burden may provide a better predictive value of future cardiovascular events than the analysis of each of the traditional risk factors alone.

欧洲已禁止在饲料中使用抗生素生长促进剂(AGPs),将来其它许多国家也将跟随其后。因此,寻找AGPs替代品将是一项不间断的探索工作。印度家禽项目董事会的科学家断定,无论何时找到AGPs替代品,天然生长促进剂可以使家禽获益。
