Abstract: To study the effects of astaxanthin supplementation on serum antioxidant capacity, blood lactic acid and blood uric acid metabolism of human body in the 1h recovery period after acute high-intensity exercise. Sixteen male students grade 2016 from Physical Education Institution (age: 19.13±2.52, height: 179±4.21cm and weight 68.23±7.81kg) were randomly divided into two groups: group A (experimental) and B (control). Group A was given astaxanthin for 28 days at a moderate dose (12 mg/d) and placebo for 28 days at group B. 4 weeks later, all subjects underwent exercise on power bike. The antioxidant capacity and blood uric acid and the content of blood lactic acid was assayed using anti-oxidation Kit (FORD), blood lactic acid Kit (LACTIC ACID), blood uric acid Kit (URIC ACID). Results: 1) One hour after exercise, the antioxidant capacity in both A and B obviously increased without exception and the value of group A was obviously higher than B. The blood lactic acid in both groups dramatically declined and the value of group A was obviously lower than B. The blood uric acid rised in both groups and the value of A was obviously lower than B. Conclusions: Pre-supplement of astaxanthin can accelerate the recovery of antioxidant capacity, accelerate the clearance of blood lactate and delay the increase of blood uric acid in the body within 1 hour after exercise.

Abstract: Artemisia afra (Jacq. Ex. Wild), or "African Wormwood" belonging to the family of Astereaces and is widely used traditionally for health care in the eastern part of Africa with few research evidence substantiating its safety. The aim of this study was to investigate the safety of the ethanolic, dichloromethane, and hexanolic extracts of Artemisia afra by determining its pharmaco-toxicological effects after an acute oral administration in mice and to test also their in vivo antimalarial effects. Oral acute doses of Artemisia afra extracts were given to thirty mice at the doses of 1000, 2000 and 2500 mg/kg of body weight. The mice were then observed for fourteen days, toxicity signs, body weight, organs weight and biochemical parameters were checked. Four days peter’s test was run on mice to determine the in vivo antimalarial activity of the plant extracts and the IC50 for each extract was determined. The results show few toxicity signs from the first two days after oral administration. There were no differences in organs weight and body weight for the experimental mice when compared to the control group. The level of alanine transaminase (ALT) and aspartate transaminase (AST) were found do not be statistically different from the control. The LD50 of the extracts was found to be greater than 2500 mg/kg of body weight. The results also showed a high antimalarial effect of the extracts when tested in vivo using Plasmodium Berghei Anka. In Conclusion Artemisia afra is a strong drug candidate for malaria with no toxic effects in high dosage.

Abstract: The physical properties of agricultural products are necessary for the design of equipment for post-harvest treatments and storage. The physical characteristics of two varieties (Ateehteu and Lamsie) of wild orchid tubers used for the production of an endogenously processed food eaten as a meat replacement were determined. Directly measured properties (tuber length, width, thickness, mass, true volume and bulk volume) and derived properties (sphericity, shape index, size, porosity, true and bulk density) were evaluated at 86.11% and 79.01% (wb) moisture contents of Ateehteu and Lamsie respectively. The mean ranges respectively recorded for Ateehteu and Lamsie were: mass (1.70 – 5.79) g; (1.24 – 7.65) g, length (18.94 – 32.01) mm; (9.84 – 27.54) mm, width (11.91 – 19.34) mm; (6.91 – 18.79) mm; thickness (5.07 – 24.50) mm; (1.09 – 22.77) mm, true volume (1.37 – 5.68) ml; (1.52 – 7.28), and bulk volume (29.67 – 30.58) ml; (31.50 – 32.84) ml. For the derived properties, Ateehteu and Lamsie respectively gave, sphericity (60.49 – 81.00)%; (62.72– 87.81)%, shape index (1.18 – 2.34)%; (1.08 – 2.19)%, true density (0.58 – 1.82) g/ml; (0.84 – 1.15) g/ml, bulk density (0.53 – 0.61) g/ml; (0.50 – 0.54) g/ml, porosity (0.76 – 1.00), (0.87 – 1.07); and bulk porosity (0.47 – 0.51); (0.45 – 0.47). The repose angle was (26.06 – 32.92)° and (28.28 – 32.86)° while the coefficient of static friction on four surfaces viz aluminium sheet, rubber, leather and plywood were (0.27 – 0.44); (0.13 – 0.63), (0.32 – 0.49); (0.88 – 0.95), (0.16 – 0.64); (0.31 – 0.55); (0.33 – 0.62); (0.48 – 2.75). There were significant variations in physical dimensions of Lamsie; larger mass and true volume, sphericity and repose angle compared to Ateehteu. There was significant variation in the coefficient of static friction on aluminium sheet, rubber, leather and plywood respectively for Ateehteu and Lamsie respectively with no variation in the coefficient of dynamic friction on the same surfaces for Ateehteu and Lamsie respectively. The negative values obtained for some derived shape parameters (flattening and ellipticity) which consequently affected the surface area is an indication that the shape assumption of the tubers as oblate or prolate requires verification. There is therefore need to correlated the directly measured properties to obtain an empirical formula to calculate each corresponding parameter and analyse to obtain the best fit. It is therefore promising to design a process plan to harvest, transports, handle, sort and separate, grade, convey stock and process the tubers into Nyam ngub.
