We collected 94 patients as the experimental group, which hospitalized in Qinghai Provincial People's Hospital, Guoluozhou People's Hospital and Qinghai University Affiliated Hospital, including 48 cases of cerebral infarction (mean age 61.39 ± 10.48 years); 46 cases of cerebral hemorrhage (mean age 63.17 ± 10.92 years), and 96 healthy Tibetan residents from the physical examination center of Qinghai Provincial People's Hospital as control group. The results showed that in In the Tibetan population, the CI group was the most common in the e3 alleles, with 48.0%, followed by e2 (37.5%) alleles, the rarest of which was e4 (14.6%). The most common one in ICH group were e2 (43.5%), e3 (45.7%) alleles, and the rarest one was e4 (10.9%). e3 was the most common allele in patients with Tibetan cerebrovascular disease. In the normal control group, e2 (49.0%) was the most common alleles, followed by e4 (33.3%), and e3 (17.7%). e3 allele may be a predisposing factor for cerebrovascular disease in Tibetan population. In Tibetan population, the majority alleles of ApoE were heterozygous E2/E3 and E2/E4, suggesting that hypoxia environment may be beneficial. The TG values in Tibetan populations varied among different alleles, suggesting that different alleles may influence lipid metabolism.","PeriodicalId":7392,"journal":{"name":"Accident Analysis & Prevention","volume":"60 1","pages":"38"},"PeriodicalIF":0.0,"publicationDate":"2018-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75157019","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This index may appear strange to a student because he could expect a cubic relation between body volume and any linear body dimension. The aim of the present experiment was to show the experimental approach to establish a mathematical relation between linear body dimensions and body weight by using a simple animal model. To this end, twelve sea bass and thirteen sea breams were obtained from a local fish-market. For each fish it was measured the body weight, the linear body dimensions, the body volume, the body surface area, and the visceral fat weight. The mathematical relations between all the experimental variables were evaluated pairwise, by plotting them on X-Y graphs and calculating the best fitting power-model. The results demonstrated that in fishes body weight fitted with any of the linear body dimensions raised to a power smaller than 2. The strongest of such correlations was between body weight and body length raised to a power of 1.5. Moreover, BMI did not correlate with visceral fat content. These results demonstrated that in fishes: 1) a non-linear correlation exists between body weight and linear body dimensions; 2) growth is allometric; 3) BMI is a fictitious index and does not describe a physiological phenomenon; 4) BMI is not predictive of visceral fat content; 5) other variables should be taken into account to obtain a more affordable mathematical model to describe the relation between body weight and linear body dimensions.","PeriodicalId":7392,"journal":{"name":"Accident Analysis & Prevention","volume":"77 1","pages":"33"},"PeriodicalIF":0.0,"publicationDate":"2018-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80526128","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In vivo experiments require the use of appropriate anaesthesia, which should be selected according to their particular effect on the organism. The aim of study was to review the status of acid-base balance and ion concentration in arterial blood under common used general anaesthesias in experiments in dependence on the light-dark (LD) cycle in spontaneously breathing rats. The experiments were performed using three- to four-month-old pentobarbital (P)-, ketamine/xylazine (K/X)- and zoletil (Z)-aneasthetized female Wistar rats after a four-week adaptation to an LD cycle (12h light:12h dark). It was concluded that P anaesthesia disturbs LD dependence of acid-base balance compared to K/X and Z anaesthesia, but LD differences in plasma ion concentrations are disturbed under all type of general anaesthesia. P anaesthesia is not the most appropriate type of anaesthesia in rat chronobiological experiments. It eliminated LD differences, and also produces a more acidic environment, more pronounced hypercapnia and hypoxia than K/X and Z anaesthesias. This should be taken into account because the altered internal environment may affect the activity of systems whose functions are primarily dependent on acid-base balance or/and ion concentrations.","PeriodicalId":7392,"journal":{"name":"Accident Analysis & Prevention","volume":"107 1","pages":"26"},"PeriodicalIF":0.0,"publicationDate":"2018-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89480491","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The stimuli were presented randomly. The subjects were to attribute them regardless of the form (a word or image) to one of the categories. 11 female and 10 male subjects (average age 21.9±2.9 years) participated in the tests. 6 components of the evoked potentials were singled out: Р1 (Р66), N1 (N124), Р2 (Р180), N2 (N248), Р3 (Р331) and N3 (N456). Analysis showed that both female and male subjects demonstrated reliably longer response time for words as compared to those for corresponding images. For words, evoked potentials were registered in more complex configurations and with a shorter latency period for the early components (P1, N1) and longer latency period for the late ones (P2, N2, P3, N3). The evoked potential amplitude in response to verbal stimuli was smaller than that for visual ones. Evoked potential components in response to target stimuli (both images and words) had, in general, shorter latency. The amplitude of N1, Р2 and N2 components was lower, while that of P3 and N3 was higher for target stimuli rather than a non-target. The obtained results allow us to assume that evaluation of the type of information (verbal or visual) can be performed on early stages of stimulus perception (up to 120-150 ms). Further analysis includes either more detailed description of spatial features of the visual stimuli in parietal and occipital lobes or estimation of the semantics of a word employing the frontal and temporal areas. Decision-making on formulating a response barely depends on the manner of information presentation (visual and verbal).","PeriodicalId":7392,"journal":{"name":"Accident Analysis & Prevention","volume":"4 1","pages":"14"},"PeriodicalIF":0.0,"publicationDate":"2018-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90570056","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The experimental design was split plot with three replications; cultivars were assigned to the main plot and planting methods to sub-plot. Data were collected at 55, 70, 85 and 100 days after planting. Leaf area index were significantly (P<0.05%) higher on sets and transplants at all dates of observation. The correlation analysis results show highly significant (P<0.001) association between plant height, leaf area, LAI and shoot fresh and dry weight, with correlation coefficient ranging between 0.89 and 0.99. This indicates that any one of these parameters can be used for yield estimator depending on the condition and the facilities available.

The test formulation was divided into two parts. One part was denoted as the control without any Biofield Energy Treatment, while the other part was defined as the Biofield Energy Treated sample, which received the Biofield Energy Healing Treatment remotely from seven renowned Biofield Energy Healers. Additionally, one group of animals also received Biofield Energy Treatment per se (day -15) by Biofield Energy Healers under similar conditions. The test formulation was evaluated for immunological parameters viz. humoral immune analysis, paw volume, hematological study, biochemistry, body weight, feed and water intake, and histopathology analysis were performed. The humoral immune response showed a significant increased primary and secondary antibody titre values by 26% and 150.4%, respectively in Biofield Energy Treatment per se group (G6, day -15), while primary and secondary antibody titre values were increased by 100.0% and 110.4%, respectively in the Biofield Energy Treated test formulation (G7, day -15) group compared with the disease control group (G2). The results of delayed type hypersensitivity showed a significant increase in the paw volume by 94.44% in the Biofield Energy Treated test formulation (G4) group with respect to the G2 group.

Material and Methods In the first study, providing a single online practice quiz followed by instructor feedback had no effect on examination average grades compared to the previous year or student performances on similar questions. However, there were significant correlations between student performance on each practice quiz and each summative examination (r 50.42 and r 50.24).

The present study was carried out on 10 male buffalo calves from birthing until 24 months of age. The animals were weighed at birth, 3, 6, 12, 18 and 24 months before the morning feed and daily body weight gain (DBWG) was calculated for 0-3, 3-6, 6-12, 12-18, 18-24 and 0-24 months. During weighing the calves, 0ne blood sample from the Jugular vein of each calf was withdrawn to estimate thyroxin (T4), triiodothyronine (T3), cortisol, testosterone and aldosterone hormonal levels as well as glucose and protein fractions. Results showed that live body weight (LBW) of calves was increased gradually from birthing to reach to 592.8 kg after 24 months of age. The lowest DBWG of buffalo calves values were through the first 3 months after birthing and the period from 18-24 months of age while the highest DBWG values were during the period from 6 to 18 months of age. The highest level of T4 and T3 were at birth and decreased significantly at weaning. The lowest cortisol level was at birth while the highest cortisol value was at weaning and after 24 months of age. The highest level of aldoserone was at birth and at weaning. From 6 months of age up to 24 months, T4, T3 and aldosterone level was not affected significantly due to the change in age of calves. Testosterone level increased progressively with increase the age of buffalo calves. T4, T3 and aldosterone hormones have negative significant correlations while testosterone level has a highly positive correlation with each of age, LBW and DBG of buffalo calves. Glucose level decreased significantly with increasing the age of calves. Glucose and globulin levels have a negative significant correlation with each of age, LBW and DBG of buffalo calves.
