DISTRIBUTION AND BIOGEOGRAPHY OF NON-MARINE CRETACEOUS TURTLES

During the Cretaceous, non-marine turtles show strong patterns of provincialism, mirroring the pattern of land masses resulting from the breakup of Pangea since the Jurassic. These patterns are a result of several factors, of which vicariancy and ecological controls on the distribution of groups of turtles are considered the most significant. The large scale patterns, such as the dominance of pleurodires in the southern land masses, including Africa, South America, and India, and the dominance of Cryptodires in the northern land masses cannot be strictly attributed to vicariancy because exceptions to both distributional patterns are present. The pleurodires in Europe and North America during the Late Cretaceous may reflect the removal of the barriers that prevented the terrestrial faunal interchange between the northern and southern continents. Two groups of cryptodires that occurred in the southern continents during the Cretaceous, the Meiolaniidae and Otwayemys , seem to reflect a widespread distribution of the very primitive cryptodires which were diverse prior to the breakup of Pangea in the Early or possibly Middle Jurassic. In Laurasia, three regions of turtle diversity can be identified, the North American region, the European region, and the Asian region. In the Early Cretaceous, North American region is dominated by members of the Paracryptodira, and the Asian region is dominated by members of the Eucryptodira. Europe includes taxa from both groups. In the Late Cretaceous, Eucryptodires become increasingly more abundant and diverse in North America. The Baenidae which are not found outside North America appears to be truly endemic to this region. Two groups of “modern,” non-marine cryptodires or Chelomacryptodira, the Testudinoidea and the Trionychoidea, appear to have an Asian origin. Both have their earliest record in the Neocomian of Japan.

Independent ambulators with high sacral myelomeningocele: the relation between walking kinematics and energy consumption

The aims of this study were to determine the relation between gait kinematics (center of mass excursions) and measures of oxygen consumption and oxygen cost. Fourteen independent ambulating children with myelomeningocele (nine females, five males; mean age 8 years 7 months) and thirteen children with no history of neuromuscular disorder were evaluated. At their comfortable walking speed all patients exhibited oxygen cost and oxygen consumption values that exceeded the normal level by more than 1 SD. Pelvic obliquity demonstrated the strongest relation with oxygen cost which suggests that ultimately hip abductor strength may play a key role in energy demands during gait. Despite the exaggerated pelvic kinematics, vertical and horizontal center of mass excursions of the trunk and whole-body during the gait cycle were not significantly greater than normal (p>0.05). Decreased self-selected walking velocity at which many of these children consider comfortable and stable may be predicated on an optimal center of mass movement that approximates the magnitude observed in normal gait. The slower walking velocity decreases walking efficiency. Conversely, the increased center of mass movement that would accompany a faster gait would probably impose intolerable oxygen consumption levels. Strengthening programs that focus on the gluteus medius and maximus to decrease compensatory trunk and pelvic motions, allowing the patients to adopt a faster gait without exacerbating kinematic and center of mass motions and which enabled more efficient walking hold promise for these patients.
Genetic Transformation of Tobacco with the Trehalose Synthase Gene from Grifola frondosa Fr. Enhances the Resistance to Drought and Salt in Tobacco

Trehalose is a non-reducing disaccharide of glucose that functions as a protectant in the stabilization of biological structures and enhances the tolerance of organisms to abiotic stress. In the present study, we report on the expression of the Grifolafrondosa Fr. trehalose synthase (TSase) gene for manipulating abiotic stress tolerance in tobacco (Nicotiana tabaccum L.). The expression of the transgene was under the control of two tandem copies of the CaMV35S promoter and was transferred into tobacco by Agrobacterium tumefaciens EHA105. Compared with non-transgenic plants, transgenic plants were able to accumulate high levels of products of trehalose, which were increased up to 2.126-2.556 mg/g FW, although levels were undetectable in non-transgenic plants. This level of trehalose in transgenic plants was 400-fold higher than that of transgenic tobacco plants cotransformed with Escherichia coli TPS and TPP on independent expression cassettes, twofold higher than that of transgenic rice plants transformed with a bifunctional fusion gene (TPSP) of the trehalose-6-phosphate (T-6-P) synthase (TPS) and T-6-P phosphatase (TPP) of E. coli, and 12-fold higher than that of transgenic tobacco plants transformed the yeast TPS1 gene.It has been reported that transgenic plants with E. coli TPS and/or TPP were severely stunted and had morphological alterations of their roots. Interestingly, our transgenic plants have obvious morphological changes, including thick and deep-coloured leaves, but show no growth inhibition; moreover, these morphological changes can restore to normal type in T2 progenies. Trehalose accumulation in 35S-35S:TSase plants resulted in increased tolerance to drought and salt, as shown by the results of tests on drought, salt tolerance, and drought physiological indices, such as water content in excised leaves, malondialdehyde content, chlorophyll a and b contents, and the activity of superoxide dismutase and peroxidase in excised leaves. These results suggest that transgenic plants transformed with the T
Activation-induced cell death in peripheral blood mononuclear cells (PBMCs) from patients with chronic hepatitis B may be related to abnormal production of interleukin 12 and 10.

Peripheral blood mononuclear cells (PBMCs) from 70 patients with chronic hepatitis B and 32 normal healthy persons were isolated and cultured with or without Staphylococcus aureus enterotoxin B (SEB; 0.2 mg l–1) and recombinant HBcAg (rHBcAg; 1.0 mg l–1) for 48 h in vitro. After incubation, the cells were harvested by centrifugation and apoptosis of the PBMCs was studied by staining with fluorescent dyes YOPRO-1 and Hoechst 33342. The levels of IL-12 and IL-10 in the serum and the supernatants of cultured PBMCs were assayed by ELISA. The levels of IL-12 heterodimer in the serum and the supernatants of PBMCs cultured with SEB or rHBcAg were lower in patients than controls. The levels of IL-10 in both the serum and supernatants were higher in patients than controls. In addition, the percentage of apoptotic cells in PBMCs from the infected patients was significantly greater than from normal persons in the presence or absence of SEB and rHBcAg. Patients seropositive for HBeAg had much greater percentage of apoptotic cells in the PBMCs cultured with rHBcAg than patients seronegative for HBeAg, reaching 24.08%. We speculate that activation-induced cell death of PBMCs in the patients with hepatitis B may be related to abnormal expression of IL-12 heterodimer and IL-10, which may lead to persistent infection in the patients.
[Overweight and obesity in children and adolescents of Corrients city. Relationship with cardiovascular risk factors ].

UNLABELLED The prevalence of children's obesity is increasing all over the world. It has been related to an increment of all morbimortality causes in the mature age. To determine the prevalence of obesity and other cardiovascular risk factors in adolescence, and correlate them with each other, we designed a cross-sectional study. A survey was applied to 2115 secondary school students, 1212 (57.3%) females and 903 (42.7%) males; blood pressure (BP) and cholesterol level were measured. Mean age: 14.8 +/- 1.6. : Body Mass Index (BMI): 20.6 +/- 3.1, 1838 (86.9%) normal, 230 (10.9%) where overweight and 47 (2.2%) obese, higher in males (OR = 1.46; IC = 1.12-1.91; p = 0.03). Weekly physical activity: 3.9 +/- 2.9 hs. higher in males (p < 0.001). Sedentarism daily hours: 3.2 +/- 1.9. ANTECEDENTS maternal obesity 282 (13.3%), paternal 311 (14.7%) and in both 116 (6.6%). Regular consumption of fatty foods: 1711 (80.9%). SBP: 107.8 +/- 13.6; DBP: 66.9 +/- 11.5; MBP: 80.5 +/- 10.1. We found hypertension in 64 (3%) prevalent in males (p = 0.002). Cholesterol: 161.9 +/- 29.2; desirable 1283 (60.7%); normal high 628 (29.5%) and high 208 (9.8%). BMI and MBP correlation was: r = 0.25; r2 = 0.06; CI 95%: 0.02-0.11; b coefficient 0.83. We found a positive correlation of BMI with MBP (0.83 mm Hg increment for each point of BMI increment). We found significant association between parental obesity and alcohol consumption and BMI increment. We did not find any association with dietary habits, physical activity or sedentarism.

Accumulation and distribution of dry matter and potassium in maize varieties released in different years

In order to compare the differences in growth,development and dry matter accumulation,as well as potassium(K) uptake and distribution in different maize varieties released in different years in China,field experiment was conducted under the same conditions and six maize cultivars released from the 50s in last century until now were employed,e.g.Baimaya,Jinhuanghou,Zhongdan 2,Tangkang 5,Nongda108 and Zhengdan 958.The result showed that new varieties had slower developmental process,longer growth duration,larger total leaf area and slower leaf senescence,compared with those of the old varieties.At V10 stage,there was no difference in plant dry weights among different maize varieties.After this stage,however,new varieties grew quicker and their dry weights increased faster than those of the old varieties.The high rate in dry matter gain of all varieties appeared after silking.The grain dry weights of all varieties were about the same as the dry matter gains of whole plants after silking,indicating that dry matter accumulated in grains was directly from the leaf photosynthesis after silking.In spite of the same plant dry weights at V10 stage,K contents in maize varieties released in different years already showed difference at this stage,and that was higher in the new varieties than those in the old varieties.Most of K in plants of all maize varieties was taken up before silking.There was even decrease in K content in old varieties Baimaya and Jinhuanghou from silking until maturity.K deposited in grains of different maize varieties came mainly from the retranslocation from the vegetative organs,especially from leaves.There was even more K retranslocated from the leaves of the stray-green varieties Nongda108 and Zhengdan 958 than that form the old varieties.In summary,new varieties had longer growth period,larger leaf area and slower leaf senescence,which were beneficial for grain milking and thus higher grain yield formation.Since the high rate in dry weight gain appeared after silking,while the most of K in plants of all maize varieties was taken up before silking,the dry matter and K accumulation in maize plants was not synchronized.Grain dry matter came mainly from the photosynthesis after silking,while grain K came from the retranslocation from the vegetative organs,regardless of the difference in varieties.
Induction of apoptosis of human gastric carcinoma SGC-7901 cell line by 8-bromo-7-methoxychrysin

Aim To investigate the effect of 8-bromo-7-methoxychrysin(BrMChR) on apoptosis of human gastric carcinoma SGC-7901 cell line.Methods SGC-7901 cells were cultured and the inhibitory effect of BrMChR on the proliferation of SGC-7901 cell line was measured by MTT assay.The apoptosis of SGC-7901 cells induced by BrMChR was analyzed using flow cytometry (FCM) with PI staining.DNA ladder bands were observed by DNA agarose gel electrophoresis.Results MTT assay suggested that BrMChR markedly inhibited the proliferation of SGC-7901 cells in a concentration-dependent manner,its IC50 was 2.6 μmol·L-1,the potency of BrMChR was 8 times more than that of lead compound,chrysin (ChR,IC50 was 16.5 μmol·L-1),and was 3 times more than that of 5-fluorouracil (5-FU,IC50 was 7.7 μmol·L-1). FCM with PI staining indicated the apoptotic rate of SGC-7901 cell line treated with BrMChR (1.25,5.00,20.00 μmol·L-1) for 48 h was (19.8%±0.2%),(36.8%±1.9%) and (45.5%±3.5%) respectively and the rate treated with BrMChR (1.25 μmol·L-1) was higher than that treated with ChR (20.00 μmol·L-1,12.9%±1.5%). DNA agarose gel electrophoresis showed that when treated with BrMChR(20.00 μmol·L-1) for 48 h,the gene DNA of SGC-7901 cells presented typical DNA ladder bands which could attenuated by the effect of pre-incubation of GW9662(10.00 μmol·L-1),a blocker of PPARγ. Conclusion BrMChR might induce apoptosis of SGC-7901 cell line partially by activating PPARγ.

Localization of a breathing crack in a stepped beam using a method of harmonic separation

The present study demonstrates a method of crack localization employing the time domain manifestation of the nonlinear acoustics generated by guided wave breathing crack interactions in a stepped beam. A method based on wavelet spectral finite elements is used to simulate the propagation of flexural wave through a stepped beam with a breathing crack. The separation of first and second harmonic at the sensor location, is related to the location of crack with respect to sensor. The marginal errors in localizing the crack ascertain the applicability of the method. As the developed technique uses the nonlinear acoustics generated by the cracks, the results are specific to the crack and therefore can be positively used in presence of the other geometric discontinuities.
Comparative Study Between Quintic and Cubic Polynomial Equations Based Walking Trajectory of Exoskeleton System

170104-6565-IJMME-IJENS © August 2017 IJENS I J E N S Abstract-Trajectory planning is the most crucial part in robot design especially for exoskeleton robot. The suitable trajectory will directly affect safety, health, and comfort of the wearer. In trajectory generation profile of lower limb exoskeleton robot, the cubic polynomial is commonly used to generate smooth trajectory generation profile. Whereas, the quintic polynomial is not widely used due to complexity. This paper aims to make comparative studies between cubic and quintic polynomials. Whereas, the accuracy of generated profile will be investigated and analyzed to understand the gap of knowledge. Based on that, the gait cycle motion is divided into seven sub-phases. Each sub-phase is presented by one polynomial equation either cubic or quintic. Accuracy analysis was involved in order to show either cubic or quintic polynomial is accurately matched to human walking motion profile. The result shows that quintic generates an accurate profile motion of ankle, knee, and hip joints with 0.4852,0.4283, 0.3917 RMS error respectively. Meanwhile, cubic polynomial generates the trajectory motion profile of ankle, knee, hip joints with 0.8417, 0.9728, 0.2639 RMS error respectively. Thus, the quintic polynomial is more accurate than cubic polynomial to generate trajectory profile with the smooth transition.
Study on ioslation of viruses from patients with hand-foot-mouth disease patients

Objective To explore the factors influencing the isolation of virus from hand-foot-month disease patients and improve the isolation rate.Methods The specimens including cerebral spinal fluid,vesicle fluid and throat swabs,were collected and inoculated into RD-A cells for isolation of enteroviruses(EV). The isolates were identified by cytopathic effect test(CPE) and then the real time reverse transcription polymerase reaction(realtime RT-PCR) for EV,Enterovirus71(Enterovirus71,EV71) and Coxsacki virus16(CA16). Results Human RD-A cells were highly susceptible to EV71,CA16 and other enterovirus.If the samples were taken within 72 hours of onset of the disease,the virus isolation rate could reach 66.7%,and it was only 29.1% in case of over 72 hours.With addition of vancomycin,amikin and nystatin in culture,the contamination rate of mciroaoganisms would reduced from 75% to 3.93%,and the isolation rate increased from 13.6% to 54.9%. Conclusions The viruses isolation rate can be greatly increased if the samples were taken in time,and effective inhition of bacterium and fungus.and properly cell inoculation density could be achieved.
Identification of Proteins Affected by Iron in Saccharomyces cerevisiae Using Proteome Analysis

To study the effect of iron on Saccharomyces cerevisiae, whole-cell proteins of Saccharomyces cerevisiae were extracted and subjected to two-dimensional polyacrylamide gel electrophoresis (2D-PAGE), and differentially expressed proteins were identified. The proteins separated were further identified by matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectrometry and were compared with a protein database. Of more than 300 spots separated by molecular weight and isoelectric points, 27 differentially expressed spots were identified. Ten proteins were found to be differentially expressed at high iron concentration. Triosephosphate isomerase (TPI), YDR533C hypothetical protein, superoxide dismutase (SOD), 60 kDa heat-shock protein (HSP60), pyruvate dehydrogenase beta subunit 1 (PDB1), and old yellow enzyme 2 (OYE2) were upregulated, whereas thiol-specific antioxidant (TSA), regulatory particle non-ATPase subunit 8 (RPN8), thiol-specific peroxiredoxin 1 (AHP1), and fructose-1, 6-bisphosphate adolase (FBA) were downregulated by iron. Based on the result, we propose that SOD upregulated by iron would protect the yeast from oxidative stress by iron, and that TSA downregulated by iron would render cells hypersensitive to oxidative stress.
Two new statistics to detect answer copying

Two new indices to detect answer copying on a multiple-choice test, S(1) and S(2) (subscripts), are proposed. The S(1) index is similar to the K-index (P. Holland, 1996) and the K-overscore(2), (K2) index (L. Sotaridona and R. Meijer, in press), but the distribution of the number of matching incorrect answers of the source (examinee s) and the copier (examinee c) is modeled by the Poisson distribution instead of the binomial distribution to improve the detection rate of K and K2. The S(2) index was proposed to overcome a limitation of the K and K2 indexes, namely their insensitiveness to correct answers copying. The S(2) index incorporates the matching correct answers in addition to the matching incorrect answers. A simulation study was conducted to investigate the usefulness of S(1) and S(2) for 40- and 80- item tests, 100 and 500 sample sizes, and 10%, 20%, 30% , and 40% answer copying. The Type I errors and detection rates of S(1) and S(2) were compared with those of the K2 and the w (omega) copying index (J. Wollack, 1997). Results show that all four indexes are able to maintain their Type I errors, with S(1) and K2 being slightly conservative compared to S(2) and w. Furthermore, S(1) had higher detection rates than K2. The S(2) index showed a significant improvement in detection rate compared to K and K2.
