Fifteen genotypes of rapeseed were used in the study of embryogenesis and temeprature treatment to the embryo induced from microspore culture. Embryo yields, frequency of normal embryo production and plant regeneration rate were greatly different between genotypes and between plants within a genotype. Embryo yield ranged from 6 to 302 embryos per bud, normal embryos ranged from 7 to 84.1% of total embryos produced, and plant regeneration from embryos showed from 0 to 35.4%, of embryos subcultured. Plant regeneration from embryo age of 28 days was most efficient by cold temperature treatment at 4℃ and exposure times for 9 days.

To obtain the basic information for rapeseed breeding, embryogenesis by microspore-developmental stages and the relationship between anther length and microspore-developmental stages were investigated. The embryogenesis by bud sizes were most efficient from 3.5 to 4.5mm for Topas and from 2.8 to 3.3 mm for MSB 69-11, and the anther lengths were from 2.0 to 2.9mm. The best response for the tested varieties was from buds with a petal/anther ratio of 2/3 and 3/4. The late uninucleate stage has been identified as optimal for embryo production in B. napus. At the late uninucleate stage the exine was rigid, dark yellow in color and the nucleus was displaced to the periphery of the cell.

High-Rosmarinic Acid Spearmint Tea in the Management of Knee Osteoarthritis Symptoms

Individuals with medically diagnosed knee osteoarthritis (OA) participated in a randomized, double-blind study to investigate the effects of a high-rosmarinic acid (rosA) spearmint tea. Sixty-two participants were randomized by sex and screening pain score to consume tea brewed from a high-rosA spearmint variety or a commercially available spearmint twice daily for 16 weeks. Pain, quality of life (QoL), and physical function at baseline and week 16 were assessed using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Short-Form 36-item Health Survey (SF-36), 6-minute walk test (6MWT), and stair climb test (SCT). Data from 46 participants (mean age = 60.7; BMI = 32.9 kg/m2) were analyzed. Pain score significantly decreased from week 0 to 16 for the high-rosA group but not for the control group and scores for stiffness and physical disability significantly decreased from week 0 to 16 for both groups. Increased QoL score on the bodily pain index in the SF-36 was observed at week 16 within the high-rosA group only, although no significant differences were observed between the groups. A nonsignificant improvement was observed in the 6MWT at week 16 in the high-rosA group only. There were no changes in the SCT for either group. Therefore, 16-week daily consumption of the highrosA and commercial spearmint teas significantly improved stiffness and physical disability scores in adults with knee OA, but only the high-rosA tea significantly decreased pain. Consumption of high-rosA tea warrants further consideration as a potential complementary therapy to reduce pain in OA. Clinical Trial Registration Number: NCT01380015.
