The purpose of this study was to clarify the effect Bovine leukemia virus (BLV) infection on natural immunity in bovine mammary gland and severity clinical mastitis. We classified milk samples from mastitic cows into BLV-positive (n=76) BLV-negative (n=12). were further divided with High BLV proviral load (H-PVL) (n=23) Low (L-PVL) (n=53). Severity mastitis as MILD, MODERATE, or SEVERE. Multiple logistic regression analysis performed host factors environmental objective variable. (PVL)...
Tick-borne encephalitis virus (TBEV) is a zoonotic agent causing severe in humans. Rodent species that are potential hosts for TBEV widely distributed various regions Japan. In this study, we carried out large-scale epizootiological surveys rodents from areas of A total 931 rodent and insectivore sera were collected field surveys. Rodents seropositive found Shimane Prefecture Honshu several Hokkaido Prefecture. These results emphasize the need further epidemiological research preventive...
Tick-borne encephalitis virus (TBEV) is a zoonotic agent causing severe in humans. A recent epizootiological survey indicated that endemic foci of TBEV have been maintained the southern part Hokkaido until recently. In this study, we sought to isolate from wild rodents area. One virus, designated Oshima 08-As, was isolated an Apodemus speciosus captured Hokuto 2008. 08-As classified as Far Eastern subtype and formed cluster with other strains 1995 1996. Thirty-six nucleotide differences...
Hemorrhagic fever with renal syndrome (HFRS) is a serious public health issue in Far East Russia. Two different hantaviruses were isolated from rodents captured the Khabarovsk region: Amur virus (AMRV; Khekhtsir/AP209/2005 strain Apodemus peninsulae ) and Hantaan (HTNV; Galkino/AA57/2002 A. agrarius ). Genetic analysis of new isolates revealed that M L segments apparently between AMRV HTNV, but S two viruses closer. The antigenicities AMRV, Seoul (SEOV) differentiated by...
European Russia is a highly endemic area of hemorrhagic fever with renal syndrome (HFRS), rodent-borne zoonotic disease, caused by hantaviruses. In total, 145 small mammals four species (Myodes glareolus, Apodemus flavicollis, A. agrarius, and uralensis) were trapped in the Samara region August 2005 examined for presence hantavirus (HV). Anti-HV antibodies found six 68 (8.8%) M. glareolus one 19 (5.3%) flavicollis indirect immunofluorescent antibody assay (IFA). The Puumala virus (PUUV),...
Hantaviruses belong to the family Bunyaviridae and are maintained in wild rodents. Although Vero E6 cells, which originate from African green monkey kidney, used widely hantavirus research, isolation of hantaviruses this cell line is difficult. To develop an efficient method propagation we established a novel line, MRK101, derived kidney grey red-backed vole ( Myodes rufocanus bedfordiae ), natural host Hokkaido virus (HOKV). The MRK101 cells showed significantly higher susceptibility...
Temperature dependencies of elastic constants and ultrasonic attenuation a polycrystalline ${\mathrm{MgB}}_{2}$ showing high-${T}_{c}$ superconductivity are reported. An electromagnetic acoustic resonance method detected the specimen's frequencies, from which we derived for nonporous using micromechanics calculation. The bulk shear moduli extrapolated to 0 K determined be 96.6 GPa 74.2 GPa, respectively, gives Debye temperature ${\ensuremath{\Theta}}_{D}=819\mathrm{K}$ coupling constant...
Abstract Hokkaido virus (HOKV) is a member of the genus Hantavirus , in family Bunyaviridae . To investigate HOKV infection host Myodes rufocanus grey red‐backed vole, 199 animals were captured at Tobetsu (October 2004 and July 2005) Nakagawa 2004) Hokkaido, Japan, for detection antibody, antigen, viral RNA. In surveys (2004) (2004), seropositive detected frequency 6.0% (5/84) 10.4% (5/48), respectively. No 2005. Seroprevalence males was 25% (1/4) 45.5% (5/11), respectively, which higher...
Abstract. Primary endometrial carcinomas from 35 non‐treated patients were investigated by measurement of andro‐gen receptors in the tumor cytosols. Receptor analysis was done with a labelled synthetic androgen, methyltrienolone 3 H‐R1881 and triamcinolone acetonide, dextran‐coated charcoal absorption. The concentrations androgen were, decreasing order: highly‐differentiated tumors, 15.7±1.8 (fmol/mg protein, mean±SE) (number cases, 21); moderately differentiated 4.6±1.6 (n = 7); poorly...
To establish a threshold value of bovine leukemia virus (BLV) proviral load (PVL) to identify increased risk severe clinical mastitis, and examine the prognosis economic loss mastitis based on newly established PVL cut-off value.97 lactating Holstein cows with mastitis.Blood milk samples were collected aseptically from each cow. Youden index was used for receiver-operating characteristic curve analysis severity rate as dependent variable an independent variable. criterion compare percentage...

Background and Objectives: Ketosis in dairy cow after parturition is a disease farms chiefly caused by lack of energy.It was examined that the preventative effect oral administration propylene glycol feeding bypass amino acids prospectively on ketosis cows.Materials Methods: Sixteen Holstein cows, serum total cholesterol concentrations <87 mg dLG 1 (72±10 ) at 2 weeks before were risk developing parturition, randomly assigned to 3 groups.Seven cows not treated (NT group), 5 orally with 90%...
In recent years, induction machine motors are operating at high speed rotation. However, an increase in iron loss occurring the core of motor when frequency is increased poses a problem. addition, alternating magnetic flux and rotating mixed core, this inner leads to factor loss. Therefore, it important clarify characteristics paper we report three-phase model under excitation.
嚢胞腎を合併し,正常レニン活性値を示した原発性アルドステロン症の1例を経験した.本症例は39才,女性.主訴は高血圧,脱力感,低カリウム血症.副腎シンチグラム,副腎静脈造影,副腎静脈採血などにより,右副腎腺腫による原発性アルドステロン症と診断され,右副腎摘出術が施行された.嚢胞腎を合併していたが,腎機能障害は軽度であつた.血漿アルドステロン値が高値を示したにもかかわらず血漿レニン活性は正常範囲であつた.手術後降圧を認め,血清カリウム値も正常化したが,血漿レニン活性は高値を示した.嚢胞腎は腎不全が進展しないうちより,高頻度に高血圧を示すが,その原因の一部にレニンーアンジオテンシン系の関与するものがあると言われている.本症例の術前における血漿レニン活性が抑制されなかつた原因としては嚢胞腎の合併によるものと考えられた.
反芻と周産期疾患との関連性について比較解析を行った．発情検知用として市販されている，反芻時間を自動計測するセンサー（反芻センサー）を周産期の乳牛の頸部に装着して反芻時間を計測するとともに，臨床観察および血液生化学検査を実施して反芻時間との関連性について比較した．その結果，周産期疾患を発症した6頭の反芻時間は，分娩14日前から分娩日にかけて周産期疾患を発症していない16頭と比較して低く推移した．また，分娩14日前から1日前までの反芻時間の平均値と分娩日の血清中NEFAの間に負の相関が認められた（r＝－0.51，P < 0.05）．更に，分娩日の反芻時間と分娩14日後の血清中BHBAの間に負の相関が認められた（r＝－0.44，P 0.05）．以上から，分娩前の反芻時間が短い場合牛は周産期疾患になりやすく，分娩前および分娩日の反芻時間とケトーシス発症の間に関連性がある可能性が示唆された．
The nucleotide sequences of membrane-bound hydrogenase small (hupS) and large (hupL) subunit genes hydrogen bacterium Alcaligenes hydrogenophilus were determined. hupS hupL encoded polypeptides 363 619 amino acids, respectively. was located upstream with 35 bp intergenic region. consensus ribosome-binding sequrnces identified the start codons hupL.
