Skeletal Muscle Adaptations to Physical Training in Type II (Non-insulin-dependent) Diabetes Mellitus

Seven middle-aged men with manifest type II diabetes mellitus underwent an endurance training programme for 10–15 weeks. The maximal aerobic capacity, as well as the endurance capacity, was improved by 10% (p<0.05). The intramuscular glycogen store increased by more than 80% (p<0.05) from 350 μmol/g dw (dry weight), and the activities of citrate synthase and 3-hydroxy-acyl-CoA dehydrogenase increased by more than 50% (p<0.05) and 30% (p<0.05). The activity of glycogen synthase was decreased by approximately 20% (p<0.05), whereas lactate dehydrogenase remained unchanged. Capillaries/fibre and fibre area increased by more than 50% (p<0.05) and 30% (p<0.05) leaving the area of supply constant. Training did not influence fasting blood lipids and glucose, glycosylated hemoglobin, oral glucose tolerance, and insulin response to an oral glucose load measured 72 hours post-exercise. It is concluded that patients with manifest type II diabetes, as normoglycaemic individuals, adapt to physical training. However, no persistent effect on glucohomeostasis and lipaemia is produced by short-term training in the diabetic patients.     

Short utterance recognition using a network with minimum training

A feedforward network is used to recognize short, digitized, isolated utterances. A high, multispeaker recognition rate is achieved with a small vocabulary with a single training utterance. This approach makes use of the pattern recognition property of the network architecture to classify different temporal patterns in the multidimensional feature space. The network recognizes the utterances without the need of segmentation, phoneme identification, or time alignment. We train the network with four words spoken by one single speaker. The network is then able to recognize 20 tokens spoken by 5 other speakers. We repeat the above training and testing procedure using a different speaker's utterances for training each time. The overall accuracy is 97.5%. We compare this approach to the traditional dynamic programming (DP) approach, and find that DP with slope constraints of 0 and 1 achieve 98.5% and 85% accuracies respectively. Finally we validate out statistics by training and testing the network of a four-word subset of the Texas Instruments (Tl) isolated word database. The accuracy with this vocabulary exceeds 96%. By doubling the size of the training set, the accuracy is raised to 98%. Using a suitable threshold, we are able to raise the accuracy of one network from 87% to 98.5%. Thresholding applied to all networks would then raise the overall accuracy to well over 99%.

This technique is especially promising because of the low overhead and computational requirements, which make it suitable for a low cost, portable, command recognition type of application.

Development of the Diploma in Clinical Dentistry (Conscious Sedation and Pain Control) Faculty of Dentistry, University of Sydney

The Diploma in Clinical Dentistry (Conscious Sedation and Pain Control) of the Faculty of Dentistry, University of Sydney, is the first dedicated programme devoted to this field in Australia. Its development followed a decision by the Dental Board of New South Wales to require a formal qualification from the University of Sydney before dental practitioners could offer sedation and pain management in practice.
The programme is conducted at Westmead Hospital in conjunction with the Department of Anaesthetics, and satisfies the guidelines developed by the Royal Australasian College of Dental Surgeons and the Royal Australasian College of Surgeons.
The course is conducted either over one or two years, with block sessions requiring attendance at Westmead Hospital, together with assignments which are completed outside the block sessions. In this way, a dental practitioner enrolled in the programme is able to continue practice.
The block sessions need not be completed over one year, but must be completed within two years.     

Coming of age: critical challenges to the future development of pediatric psychology

Described five professional challenges that will affect the future development of pediatric psychology: specialization and professional identity, relationships with other professions, securing resources necessary for effective functioning, the conflict between clinical service delivery and prevention, and development of training models. To meet these challenges, pediatric psychologists need to maintain strong connections with other psychologists, develop new models of collaborative training, practice, and research, emphasize prevention activities, and enhance the scientific basis of pediatric psychology through innovative training programs and support for faculty development.

A computer and video display based system for training eccentric viewing in macular degeneration with an absolute central scotoma

A new approach designed to establish the most suitable area for eccentric viewing and to teach and train patients with severe age-related macular degeneration (AMD) to use the eccentric viewing technique is described. Using a computer and video display based system, as well as software written specifically for this purpose, we investigated and trained ten consecutive patients with AMD. The patients were 80.1 ± 5.6 years old, on average. All of them had an absolute central scotoma. Mean visual acuity was 0.035 ± 0.016. After 30 min of testing, instruction and reading on the screen, followed by 2.6 ± 0.69 one-hour training sessions, on average, with the low vision therapist, reading newspaper and book texts with the aid of hyperoculars or aplanatic systems and a very short reading distance, the patients achieved a reading speed of 58.9 ± 19.7 words/min, significantly (p<0.001) higher than the initial speed when reading on the screen, 11.5 ± 4.5 words/min.

高温高湿环境下守岛官兵训练时脑血流和脑电生理的变化研究

目的 探讨高温高湿环境下守岛官兵训练前后脑血流和脑电生理的变化,为临床防治热致疾病提供依据.方法 从守岛官兵中随机抽取在常温常湿环境下温度(27.40±1.37)℃,湿度(50.25±6.76)%]新兵100名为常温新兵组,高温高湿环境下(温度≥35℃,湿度≥80%)新兵100名为高温新兵组;高温高湿环境下服役2～3 年的官兵100名为高温老兵组.受试者负重15 kg,分次在3000 m/15 min,5000 m/30 min和10 000 m/45 min内完成跑步训练.10 000 m训练后,根据受试者脑血流高低又分为脑血流增高组(24名)、脑血流降低组(46名)和脑血流正常组(230名).训练前后行经颅多普勒血流诊断仪和脑电图仪检测.结果 (1)3000 m训练后3组受试官兵脑平均血流速度(Vm)较训练前均显著增高(P＜0.01),但5000 m和10 000 m训练后,常温新兵组降低6%和16%,高温老兵组降低5%和15%,高温新兵组降低14%和31%,比常温新兵组和高温老兵组低(P＜0.01);(2)10 000 m训练前后3组脑电图均在正常范围,3组比较差异无统计学意义(P＞0.05);(3)10 000 m训练后脑血流增高组和降低组脑电图比正常血流组活跃(P＜0.01).结论 高温高湿环境下10 000 m训练对官兵的脑血流有较大的影响,但对脑电生理无影响,老兵在此环境下则表现出较好的热耐受力和适应性.
