A 5-year-old castrated male domestic shorthair cat was diagnosed with diabetic ketoacidosis and severe insulin resistance. Although the conventional treatment for diabetic ketoacidosis was provided, the cat required frequent hospitalization because of severe dehydration and repeated diabetic ketoacidosis. We detected anti-insulin antibodies for human in this cat. Serum insulin-binding IgG levels were markedly elevated compared with those in healthy cats and other diabetic cats. We initiated prednisolone to suppress the effects of anti-insulin antibodies. After initiation of prednisolone, the cat was gradually recovered with increasing activity and appetite. Furthermore, satisfactory glycemic control was achieved with combined subcutaneous injection of insulin detemir and insulin degludec. 相似文献

Through a series of workshops with the stakeholders including nursery operators, tree farmers, staff of the Department of
Environment and Natural Resources, local government units and the academe, a forestry seedling nursery accreditation policy
was developed. The resulting policy was subsequently implemented by the municipal government of Palompon, Leyte. The accreditation
policy encouraged nursery operators to follow smallholder-based best management practices for tree nurseries. Implementation
of the nursery accreditation policy improved farmers’ knowledge and skills in the production of high quality seedlings, encouraged
adoption of BMP for forest nurseries, provided additional source of income for the farmers, enabled members of the groups
operating the communal nursery to forge closer relationship with each other, encouraged utilization of farmers’ free time
in productive activities, developed farmers’ confidence in producing high quality planting materials, and gained for the farmers
favourable attention from various organizations and groups. The Bennett’s hierarchy of project outcomes showed that the implementation
of accreditation scheme achieved high levels of outcomes, indicating that it led to substantial improvements in the lives
of the farmers. 相似文献

ABSTRACT: Change in the translucency of squid mantle muscle during itsstorage at 0°C was studied by monitoring L* valueand turbidity. Two indicators showed that squid mantle muscle lostits translucency and reached maximal turbidity within 24 hof storage. Thickness of mantle muscle also increased by 15% in12 h, earlier than the loss of translucency. ATP contentdecreased with storage time and was completely lost in almost 24 h,a similar period to translucency loss, but later than rigor contraction.Development of black color on skin surface by chromatophores wasfully achieved in 24 h. It was thus concluded that ATPcontent was well correlated with a loss of translucency or increasein the turbidity of mantle muscle and development of dark coloron the surface skin of mantle. 相似文献

The American Samoa fishing ground is a dynamic region with strong mesoscale eddy activity and temporal variability on scales of <1 week. Seasonal and interannual variability in eddy activity, induced by baroclinic instability that is fueled by horizontal shear between the eastward‐flowing South Equatorial Counter Current (SECC) and the westward‐flowing South Equatorial Current (SEC), seems to play an important role in the performance of the longline fishery for albacore. Mesoscale eddy variability in the American Samoa Exclusive Economic Zone (EEZ) peaks from March to April, when the kinetic energy of the SECC is at its strongest. Longline albacore catch tends to be highest at the eddy edges, while albacore catch per effort (CPUE) shows intra‐annual variability with high CPUE that lags the periods of peak eddy activity by about 2 months. When CPUE is highest, the values are distributed toward the northern half of the EEZ, the region affected most by the SECC. Further indication of the possible importance of the SECC for longline performance is the significant drop in eddy variability in 2004 when compared with that observed in 2003 – resulting from a weak SECC – which was accompanied by a substantial drop in albacore CPUE rates and a lack of northward intensification of CPUE. From an ecosystem perspective, evidence to support higher micronekton biomass in the upper 200 m at eddy boundaries is inconclusive. Albacore's vertical distribution seems to be governed by the presence of prey. Albacore spend most of their time between 150 and 250 m, away from the deep daytime and shallow nighttime sonic scattering layers, at depths coinciding with those of small local maxima in micronekton biomass whose backscattering properties are consistent with those of albacore's preferred prey. Settling depths of longline sets during periods of decreased eddy activity correspond to those most occupied by albacore, possibly contributing to the lower CPUE by reducing catchability through rendering bait less attractive to albacore in the presence of prey. 相似文献

Diagnosis of corpus luteum (CL) function by rectal palpation (RP) has been widely used for recipient selection of embryo transfer (ET), a technology essential for genetic improvements in cattle. To examine the accuracy of RP diagnosis method, the relationship between RP‐based CL function and reproductive performance was compared in this study. In Experiment 1, CL of Holstein heifers on day 7 after estrus was classified into functional or hypoplastic by RP, and the results were compared with ultrasonographic (US) images and plasma progesterone (P4) levels. As a result, heifers with functional CL judged by RP had a mean maximum CL diameter of 20.1 ± 3.1 mm on US and a mean P4 concentration of 8.1 ± 2.3 ng/mL. These values were significantly greater than those of heifers with hypoplastic CL (12.4 ± 5.4 mm, 4.0 ± 2.8 ng/mL) (P < 0.001). In Experiment 2, the length of the estrus cycle was examined between functional CL and hypoplastic CL. The rate of heifers with a normal estrus cycle length with 18–25 days was significantly lower with hypoplastic CL than with functional CL (16/24 vs. 43/46, P < 0.01). In Experiment 3, 543 inseminated heifers were similarly classified by CL function by RP 7 days after estrus. The heifers with functional CL showed higher pregnancy rate compared with the heifers with hypoplastic CL (75.2 vs. 47.9%, P < 0.0001). Finally, the CL function of 66 heifers was examined by RP on day 7 post‐estrus, and ET was performed in 49 (74.2%) heifers with functional CL. As a result, 27 (55.1%) of them became pregnant. Taken together, these results reconfirm that RP on day 7 after estrus is useful for selection of heifers with functional CL. 相似文献

A comparative analysis of the elasticity, microstructure and thermal stability of fibres (thickness ranging from 43.4 to 189.4 µm) isolated from pineapple leaves (PALF), coconut coir (COIR), banana leaf-stem (BAN) and oil palm empty fruit bunch (OPEFB) reported in this study. Statistical analysis of the mechanical properties derived from tensile test to rupture reveals significant differences (P<0.05) in the fibre strength (σ), stiffness (E) and extensibility (parameterized by the strain to rupture, ?). It is observed that COIR fibres yield the smallest strength, σ (=99.8±22.5 MPa), and stiffness, E (= 0.5±0.1 GPa), while PALF fibres yield the largest σ (=639.5±301.6 MPa) and E (=7.1±3.1 GPa); PALF fibres exhibit the smallest ? (=0.11±0.03) but OPEFB fibres yield the largest ? (=2.0±1.3). From scanning electron micrographs, it is observed that cellulose fibril rupture predominates in OPEFB, COIR and BAN fibres; a large proportion of the cellulose fibrils fail by pullout in PALF fibres. Thermogravimetric analysis reveals that all fibres are thermally stable up to 250 °C; the fibre residue ranges from 30 to 80 wt% after heating to 500 °C. In particular, BAN experiences the highest weight loss and PALF experiences the lowest weight loss. The findings lend to a simple approach for determining the performance of the composites by assessing the type of natural fibres for reinforcing polymeric matrices. 相似文献

Inflammatory airway disease (IAD) is a common cause of poor performance, interruption of
training and premature retirement in racehorses. It is also reported that up to 80% of
horses are affected at some point in the first years of training in UK and Australia.
However, no studies with regard to the information on occurrence of IAD in Japanese
Thoroughbred racehorses have been reported. To investigate the occurrence and the
characteristics of IAD, epidemic research including endoscopic examination of the airway
tract and trachea wash was conducted for Thoroughbred racehorses presenting coughs or poor
performance which airway tract disease was suspected stalled in training facility managed
by Japan Racing Association. Fifty-six out of 76 Thoroughbred racehorses (73.7%)
presenting coughing or poor performance were diagnosed as IAD. Mean incidence rate of IAD
was 0.3% and it has been confirmed that constant number of IAD exists in Japan. Up to
35.7% of IAD horses showed upper airway abnormalities in some extent. There was a trend
for IAD horses to use wood shavings for bedding and fed hay from the ground compared with
the control group. Therefore, improvement of stabling environment may aid in preventing
IAD. This study demonstrated that Japanese Thoroughbred racehorses are affected by IAD
likewise other countries as well as demonstrated the characteristics of IAD which may
contribute to the clarification of the pathogenesis of IAD. 相似文献

ABSTRACT: Purified trimethylamine- N -oxide demethylase (TMAOase)from walleye pollack muscle is a thermostable protein that was notinactivated after heating at 80°C for 30 min.The heated enzyme was electrophoresed in the same manner as fornative enzyme. Circular dichroism (CD) spectra for purified enzymechanged reversibly in the temperature range of 10–80°C.As the enzyme was still active at 80°C, the CD spectralchange did not directly relate to enzyme activity. TMAOase activity inthe myofibrillar fraction decreased sharply above 30°C,but was extracted and recovered from the heated myofibrillar fraction,suggesting that the activity seemed to be interrupted and apparently inactivateddue to the thermal alteration of myofibrillar proteins or some unknownfactors. The complicated profile found in dimethylamine (DMA) formationfrom trimethylamine- N -oxide (TMAO) in walleye pollack muscleduring heating consisted of both enzymic and non-enzymic processes.Most DMA was produced enzymatically below 40°C and interruptedabove 40°C. Therefore, DMA and trimethylamine was formednon-enzymatically at high temperatures regardless of the presenceof native enzyme. A new, simple and easy purification method wasproposed based on the thermostable nature of the enzyme. 相似文献

Feral raccoons (Procyon lotor) have been growing in number in Japan, and they are becoming a problematic invasive species. Consequently, they are commonly captured and killed in pest control programs. For effective population control of feral raccoons, it is necessary to understand their reproductive physiology and ecology. Although the reproductive traits of female raccoons are well known, those of the males are not well understood because specialized knowledge and facilities are required to study them. In this study, we first used a simple evaluation method to assess spermatogenesis and presence of spermatozoa in the tail of the epididymis of feral male raccoons by histologically examining the testis and epididymis. We then evaluated the possibility of using 7 variables—body weight, body length, body mass index, testicular weight, epididymal weight, testicular size and gonadosomatic index (GSI)—to estimate spermatogenesis and presence of spermatozoa
in the tail of the epididymis. GSI and body weight were chosen as criteria for spermatogenesis, and GSI was chosen as the criterion for presence of spermatozoa in the tail of the epididymis. Because GSI is calculated from body weight and testicular weight, this model should be able to be used to estimate the reproductive state of male raccoons regardless of season and age when just these two parameters are known. In this study, GSI was demonstrated to be an index of reproductive state in male raccoons. To our knowledge, this is the first report of such a use for GSI in a member of the Carnivora. 相似文献
