世界野生虎(Pantheratigris)传统上被划分为8个亚种,其中3个亚种已于20世纪灭绝,而剩余种群的生存仍然受到偷猎、栖息地丧失和片断化的威胁。作为唯一栖息着4个现存虎亚种的国家,中国在世界虎的保护事业中负有重要责任,然而其野生和圈养虎的分类地位却仍然不确定。最近一项研究(luoetal,2004)从所有现存野生虎分布地区(包括中国)采集了134份“基准样品”(即原产野外或有确定地域起源的个体生物样品),对虎的系统地理学、种群结构以及遗传起源进行了全面分析。所用的分子标记包括四千碱基对的线粒体dNA、30个核基因组微卫星位点,以及MHC-dRB基因。研究结果表明,虽然虎的整体遗传多态性较低,但是种群分化程度很高,它们被划分为6个,而不是5个现存亚种(1)西伯利亚虎(***);(2)苏门答腊虎(***);(3)孟加拉虎(***);(4)华南虎(***);(5)印支虎(***);(6)新定义的亚种马来虎,暂命名为***。由于所研究样本量有限,目前暂定的华南虎亚种还需进一步确定。现有华南虎圈养种群包括遗传关系相距较远的两支一支与印支虎(***)无异;而另一支则与其他种群均相距甚远,可能代表了真正的华南虎(***)。利用分子生物学方法对中国动物园中圈养虎的遗传起源调查亟待进行,以确认该圈养种群整体的遗传独特性或者非独特性。换言之,这将是确认华南虎是否仍然存在的关键。

The Making of a Health Profession:How Chinese Medicine Became a Nationally Registered Allied Health Profession in Australia

引用

Chinese Medicine and Culture 2024年第1期7卷 51-62页

作者： John l Mcdonald Judy B james School of Chinese Medicine Endeavour College of Natural HealthSouthport 4215Australia Acupuncture Now Australia Brisbane 4120Australia

In 2012, traditional Chinese medicine(TCM) practitioners in Australia became nationally-registered allied health professionals in three categories: acupuncturist, Chinese herbal medicine practitioner, and Chinese herbal medicine dispenser. Australia was the first Western country to introduce national registration for Chinese medicine, followed by Portugal and, recently, New Zealand. The practice of TCM in Australia can be traced back to the beginning of Chinese immigration to Australia during the Victorian Gold Rush which began in the 1850s. The process which led to national registration commenced in the early 1970s with the establishment of the first acupuncture courses. decades of gradual development of courses from unaccredited part-time diplomas to accredited bachelor degrees, and the development, by the profession, of national consensus on educational standards were essential elements in the process which led to registration. Professional associations, such as the Australian Acupuncture and Chinese Medicine Association ltd.(AACMA), also developed a framework of professional selfregulation, including Codes of Ethics, Codes of Conduct, ongoing professional development requirements and Infection Control Guidelines, and provided leadership in the development of the profession. After decades of tribalism and division within the TCM profession, the National Academic Standards Committee brought almost all stakeholders together to reach a consensus on the Australian Guidelines for Traditional Chinese Medicine Education which were published by AACMA in 2001. Professional associations also collaborated on joint submissions to the government in support of registration, which was introduced first in the state of Victoria in 2000, and subsequently became national in 2012. despite national registration, some barriers still remain, and professional associations continue to lobby the federal government for inclusion in Medicare, chronic disease management scheme, and Veterans

Isolated lumbar Extension Resistance Training Is Effective at Improving Extension Power and disability in Subjects with diagnosed lumbar Multifidus dysfunction

引用

Open Journal of Therapy and Rehabilitation 2024年第3期12卷 245-255页

作者： William Roger Peters james Thomas Ernest smith Mario Guiseppe Zotti Adam leslie lincoln Benjamin james Enser Faculty of Medicine & Health Sciences Bond University Queensland Australia Back Neck Clinic Bundall Queensland Australia Kieser Australia Bundall Queensland Australia

Background: lumbar multifidus dysfunction is a prevalent cause of disability in individuals with lower back pain. Previous research highlights the benefits of isolated lumbar extension training for non-specific lower back pain, however, studies examining its efficacy in lumbar multifidus dysfunction are lacking. Objective: To evaluate the effectiveness of isolated lumbar extension resistance training on disability and strength in individuals with lumbar multifidus dysfunction. Methods: Subjects underwent a physiotherapy led structured rehabilitation program incorporating isolated lumbar extension. Sessions were conducted twice weekly targeting momentary muscular failure with time under load 90 - 120 seconds and progressions aimed at 5 - 10 lbs increments. Outcomes were assessed using the Oswestry disability Index and lumbar extension strength testing at baseline and after 12 weeks, with statistical analysis using t-test and chi-squared 2 × 2. Results: Forty-five subjects (24 male, 21 female) with a median age of 48 completed the intervention. Improvements were noted in Oswestry disability Index scores (median pre: 24, post: 15) and maximal lumbar extension strength (median pre: 122 lb, post: 186 lb), with p ≤ 0.05. Overall, 89% showed improvement in disability scores, 67% moved to a better disability category, and 51% saw at least a 50% increase in strength. No significant gender differences were observed. Conclusions: Isolated lumbar extension resistance training is effective at improving extension power and disability in subjects with lumbar multifidus dysfunction.

Metal oxide charge transport materials are preferable for realizing long-term stable and potentially low-cost perovskite solar cells(PSCs).However,due to some technical difficulties(e.g.,intricate fabrication protocols,high-temperature heating process,incompatible solvents,etc.),it is still challenging to achieve efficient and reliable all-metal-oxide-based ***,we developed efficient inverted PSCs(IPSCs)based on solution-processed nickel oxide(NiO_(x))and tin oxide(SnO_(2))nanoparticles,working as hole and electron transport materials respectively,enabling a fast and balanced charge transfer for photogenerated charge *** further understanding and optimizing the perovskite/metal oxide interfaces,we have realized an outstanding power conversion efficiency(PCE)of 23.5%(the bandgap of the perovskite is 1.62 eV),which is the highest efficiency among IPSCs based on all-metal-oxide charge transport *** to these stable metal oxides and improved interface properties,ambient stability(retaining 95%of initial PCE after 1 month),thermal stability(retaining 80%of initial PCE after 2 weeks)and light stability(retaining 90%of initial PCE after 1000 hours aging)of resultant devices are enhanced *** addition,owing to the low-temperature fabrication procedures of the entire device,we have obtained a PCE of over 21%for flexible IPSCs with enhanced operational stability.
