We isolated two pseudorabies virus (PRV) isolates (designated OT-1 and OT-2) from two hunting dogs exhibiting neurological manifestations after eating the flesh of wild boar hunted in Oita prefecture, Kyushu Island, Japan. The isolates corresponded to a previously reported PRV (MY-1 strain) isolated from a hunting dog in neighboring Miyazaki prefecture, and it clustered into genotype II based on the glycoprotein C sequence. Our results suggest that this common PRV strain may have been maintained in wild boars on Kyushu Island even though domestic pigs in this area have attained an Aujeszky’s disease-free status. 相似文献

ABSTRACTA study to determine the quality of laminated veneer lumber (LVL) from samama wood (Anthocephalus macrophyllus) was carried out. Samama is a fast-growing endemic wood in eastern Indonesia. Factorial of three factors in RAL design was used to investigate the influence of veneer thickness, juvenile proportion and veneer lay-up to the quality of the resulted samama LVL. The veneer thicknesses were 1.5 and 3.0?mm. Juvenile proportions were arranged in five levels, which were 100% of juvenile veneer, 100% of mature veneer and combination of both juvenile and mature with juvenile proportion of 14%, 43% and 71%. Two veneer lay-up used in this study were loose side met loose side and tight side met loose side. The result of the study showed various specific gravity of LVL by different proportions of juvenile. This factor also affected the other physical traits. Shear strength of the LVL was equal to the solid wood, yet MOE and MOR were affected by juvenile proportion and veneer lay-up. LVL developed from 100% of mature veneer exhibited the highest MOE and MOR, yet no significant difference was noted in MOE and MOR between LVL 100% of juvenile and other tested juvenile proportions. 相似文献

To estimate the potential bonding performance of bonded wood products from tropical fast-growing tree species, a study on
the bondability of Paraserianthes falcataria L. Nielsen, Pinus merkusii Jungh et. De. Vriese, and Acacia mangium Willd from Indonesia was conducted. Two-ply laminations were produced using polyvinyl acetate emulsion (PVAc), urea formaldehyde
(UF), resorcinol formaldehyde (RF), and water-based polymer isocyanate (API) adhesives. In order to determine the bonding
performance, the block-shear test was applied according to the Japanese Agricultural Standard for structural glued laminated
timber under normal conditions and after accelerated-aging treatments. To support this study, the wettability of each wood
species was also investigated through contact-angle measurement. The results showed that the bonding performance of low-density
P. falcataria was better than that of medium-density P. merkusii and medium-density A. mangium, while the bonding performance of medium-density P. merkusii was better than that of medium-density A. mangium. Furthermore, compared with A. mangium, the small contact angle and good wettability in P. falcataria and P. merkusii result in better adhesion and more intimate contact between the wood surfaces and adhesive. 相似文献

The effects of curing time at room temperature and methanol extracts from Acacia mangium on the curing behavior of resorcinol formaldehyde (RF) adhesive were examined by using the thermomechanical analysis spring
method. For a specimen that was cured for 3 months at room temperature, the relative elasticity (E
r) curve did not change to a hard glass state from room temperature to 200°C and the adhesive had cured completely. The initial
temperature of the reactive zone for chemical and mechanical changes was 15° and 25°C higher than that for the control when
10 and 15 parts by weight methanol extract was added to the liquid adhesive, respectively. It appears that the extractives
of A. mangium in RF adhesive interferes with the chemical cure of the adhesive. It is suggested that a combination of curing time and sweeping
by methanol on the laminae surface can improve the bonding performance of A. mangium laminates bonded with RF at room temperature. 相似文献

The protein from the seeds of melinjo ( Gnetum gnemon ) was purified using a precipitation method and ion exchange chromatographic techniques to identify the potent antioxidant and free radical scavenging activities. Two antioxidant protein fractions were isolated from G. gnemon seed with molecular weights of approximately 30 kDa (Gg-AOPI) and 12 kDa (Gg-AOPII) by SDS-PAGE. The N-terminal amino acid sequence of Gg-AOPII is Gly-Asn-Gly-Lys-Ala-Thr-Val-Ala-Ile-Leu-Val-Lys-Glu-Lys-Val-Glu-Tyr-Gly-Glu-Glu, and the result of matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS) analysis showed that they were distinct from each other; no protein in database matching was found to both Gg-AOPI and Gg-AOPII. The antioxidant or free radical scavenging activities of Gg-AOPs were investigated by employing in vitro assay systems including the inhibition of linoleic acid autoxidation, scavenging effect on α,α-diphenyl-β-picrylhydrazyl free radical (DPPH), 2,2'-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), reducing power, chelating abilities of metal ions Cu(2+) and Fe(2+), and protections against hydroxyl radical-mediated DNA damages. The result showed that two protein fractions exhibited significant (p < 0.05) antioxidant activities against free radicals such as DPPH, ABTS, and superoxide anion and showed activities similar to those of glutathione (G-SH) and BHT in a linoleic acid emulsion assay system. Moreover, Gg-AOPI and Gg-AOPII also exhibited notable reducing power and strong chelating effect on Fe(2+) and protected hydroxyl radical induced oxidative DNA damage. The data obtained by the in vitro systems obviously established the antioxidant potency of Gg-AOPs. 相似文献

The vitamin A status of 101 pregnant women attending clinic at the University of Calabar Teaching Hospital (UCTH), Calabar, Nigeria was assessed based on 24 h dietary recall, serum retinol concentration, history of night blindness, physical appearance and clinical eye signs. The study revealed that the mean dietary vitamin A intake of the respondents (2645.31 +/- 188.91 microg RE) and their mean serum retinol concentration (31.18 +/- 2.94 microg dL(-1)) were significantly (p < 0.05) higher than the FAO/WHO recommended intake and cutoff level for VAD. No case of night blindness, physical signs and symptoms, or clinical eye signs attributable to VAD was observed. There was a significant (p < 0.01) correlation between the amount of 24 h vitamin A intake of the women and their serum retinol concentration (r = 0.31). Also, women who had above 50% of their vitamin A intake from provitamin A sources had a significantly (p < 0.05) lower serum retinol concentration (23.10 +/- 21.12 microg dL(-1)) than those who had above 50% intake from preformed sources (49.54 +/- 42.63 microg dL(-1)) and those with about equal intake from both sources (55.75 +/- 30.80 microg dL(-1)). There was a significant (p < 0.05) and steady decline in serum retinol concentration in the women from the first trimester (37.79 +/- 6.65 microg dL(-1)), through the second trimester (35.12 +/- 4.72 microg dL(-1)), to the third trimester (21.54 +/- 1.46 microg dL(-1)) of pregnancy. 相似文献

Repeatedly thermoxidized palm oil (TPO), simulating local culinary practice, was fed for eight weeks at 15% of a balanced basal diet to two sets of male and female weanling albino rats of Wistar strain. The first set of animals were normal and healthy while the second set were kwashiorkoric. Primary controls (PC) of all rats were fed a balanced basal diet of commercial rat pellets while secondary controls (SC) were fed the balanced basal diet supplemented with 15% untreated palm oil. The findings indicate that fertility, as expressed by the pregnancy rate of healthy test rats, was 78% when compared with 80% in PC (p < 0.05). Fetotoxicity was additionally observed in that neonatal birth weights and litter size in test rats (4.92 g and 6.70, respectively) were inferior (p < 0.05) to both SC and PC (4.96 g and 8.40; 5.38 g and 9.25, respectively). Protein energy malnutrition worsened the observed TPO-induced reproductive toxicities in that reproductive capacities of the rehabilitated animals were inferior to that of the healthy animals. Pregnancy rates in test animals were reduced by as much as 55% (p < 0.01) while fetotoxicities were also more pronounced (p < 0.05). 相似文献

Caffeine and theobromine contents (mg/g) weredetermined in samples of selected Nigerian beverageproducts. The beverages were cocoa (Milo, Bournvita,Rosevita and Enervita), coffee (Nescafe, Bongo, and Maxwell House decaffeinated) and tea (Lipton). The theobromine contentsof samples of Milo, Bournvita, Rosevita, Enervita, Nescafe, Bongo, Maxwell Housedecaffeinated coffee and Lipton were 62.10 ± 5.21, 64.80 ± 6.72, 82.80 ± 4.43, 80.37 ± 6.80, 27.00 ± 4.31, 14.67 ± 2.90, 23.46 ± 3.13 and 12.60 ± 1.52 respectively. The corresponding caffeine contents of these samples were 2.78 ± 0.43 (Milo), 3.17 ± 0.36 (Bournvita), 0.92 ± 0.51 (Rosevita), 1.05 ± 0.68 (Enervita),93.66 ± 8.91 (Nescafe), 6.47 ± 2.42(Bongo), 37.22 ± 5.34 (Lipton), and 0.21 ± 0.11 (Maxwell House decaffeinatedcoffee). Semi-processed cocoa beverages (Rosevita and Enervita) had significantly (p < 0.05) higher levels oftheobromine compared with the finished cocoas (Milo and Bournvita). Similarly, Nescafe contained significantly (p < 0.05) higher levels of caffeinecompared to Maxwell House (decaffeinated coffee) and Bongo. Levels of caffeine in Lipton tea were moderate. 相似文献

The nutritional quality of the dry fruit ofTetrapleura tetraptera, a tropical deciduous forest tree with characteristic fruits, used as a spice, was assessed. The fruit shell, fruit pulp and seed contained varying amounts of nutrients such as protein, lipids and minerals, which were comparable and some were even higher than popular spices such as red pepper, onion, curry and ginger. The crude fibre content of the fruit shell was noteworthy and can be considered a good source of this nutritional factor. The distribution of crude lipids which indicated the location of the aroma of the spice, would enhance the processing of the fruit and improve its use. 相似文献
