Hegemonic gender in Japanese as a foreign language education: Australian perspectives

This chapter contests the current practice of Japanese language teaching which perpetuates and reproduces gender stereotyping and gendered language norms. It is the first of its kind which examines this question from both learner's and teacher's perspectives.

In vitro susceptibility to antimycotic drug undecanoic acid, a medium-chain fatty acid, is nutrient-dependent in the dermatophyte Trichophyton rubrum

The antimycotic activity of fatty acids has long been known, and their presence in human skin and sweat appears to protect the host against superficial mycoses. Undecanoic acid is a medium-chain fatty acid that has been used in the treatment of dermatophytoses in humans. In this study, we selected one Trichophyton rubrum undecanoic acid-resistant strain that showed a marked reduction in its capacity to grow on human nail fragments, which correlated with the reduced activity of secreted keratinolytic proteases. Moreover, the susceptibility of T. rubrum to undecanoic acid is also dependent on the carbon source utilized by both control and resistant strains. The growth of the control strain was strongly inhibited by undecanoic acid in Sabouraud medium or in cultures supplemented with low-fat milk, whereas it was ineffective when the cultures were supplemented with Tween 20 or keratin as the carbon source, suggesting that nutrient conditions are crucial in establishing a susceptibility to antifungal drugs, which is helpful for the isolation and characterization of resistant strains, and in the screening for new antifungal drugs.

Supplemented tissue culture medium 199 is a better medium for in vitro maturation of oocytes from women with polycystic ovary syndrome women than human tubal fluid

Objective: To compare oocyte maturation, fertilization and cleavage rates, and embryonic developmental quality after culture of human immature oocytes from polycystic ovary syndrome (PCOS) patients in human tubal fluid (HTF) or tissue culture medium (TCM) 199. Design: Prospective, randomized, controlled trial. Setting: University hospital. Patient(s): Thirteen women undergoing 23 in vitro maturation cycles, from whom 119 oocytes were retrieved. Intervention(s): Cumulus-enclosed germinal vesicle-stage oocytes matured in TCM-199-supplemented or HTF-supplemented media. Main Outcome Measure(s): Oocyte maturation and fertilization rates, embryonic developmental quality. Result(s): Significant differences were observed between TCM 199 and HTF regarding maturation rate (82% vs. 56.9%), fertilization rate (70% vs. 39.4%), and embryo quality (81.3% vs. 41.7%). Conclusion(S): Human tubal fluid medium, although widely used for embryo fertilization and maintenance in IVF techniques, is not,in appropriate medium for the maturation of oocytes obtained from PCOS patients in nonstimulated cycles.
