A six-year-old intact female Maltese dog weighing 3.8 kg presented with a history of mild lameness and swelling on both forelimbs. Radiographic and computed tomographic views revealed an extensive periosteal reaction in all four limbs and a large round mass on the right middle lung lobe. A total lobectomy was performed and pulmonary adenosquamous carcinoma was histologically confirmed. A diagnosis of hypertrophic osteopathy (HO) secondary to a lung tumor was made. Periosteal proliferation decreased significantly after surgery; however, there was evidence of dyspnea, mass recurrence, and periosteal reaction three months post-operatively. This is the first case report of pulmonary adenosquamous carcinoma with HO in a dog in which we describe clinical, imaging, surgical, and histological findings.

The present study aimed to evaluate the effect of propofol and thiopental on the plasma oxidant-antioxidant profile in dogs undergoing surgery at doses used to induce anesthesia. The plasma total oxidant status (TOS) and oxidative stress index (OSI) levels increased significantly with time in both groups, whereas the plasma total antioxidant status (TAS) levels decreased with time in both groups. The OSI was significantly higher at the end of surgery than before induction of anesthesia in both groups. The TOS and OSI change ratio of propofol group were significantly lower than that of thiopental group. In conclusion, our findings show that propofol has antioxidant effects in dogs. Further studies need to be conducted to demonstrate the exact mechanism of oxidative stress due to anesthesia and surgery in dogs.

The second malignancies are frequent complications in the human patient with chronic lymphocytic leukemia (CLL). However, the clinical details and outcome of this phenomenon were unclear in the canine counterparts. Here we report a dog with high-grade lymphoma concurrent with T-cell CLL. A 10-year-old male golden retriever presented with lymphadenopathies. The lymph nodes contained large-sized lymphocytes, raising suspicion of high-grade lymphoma. Meanwhile, small-lymphocytic lymphocytosis in the peripheral blood was consistent with CLL. Interestingly, molecular biological analyses revealed that CLL cells were T-cell type, whereas lymphoma cells were B-cell type. Chemotherapy using the L-VCA short protocol was effective for 155 days, but the dog died on day 194 after diagnosis, despite rescue therapies.

Matrix metalloproteinases (MMPs) play an important role in degeneration of the matrix associated with bone and cartilage. Regulation of osteoclast activity is essential in the treatment of bone disease, including osteoporosis and rheumatoid arthritis. Polyphenols in green tea, particularly epigallocatechin-3-gallate (EGCG), inhibit MMPs expression and activity. However, the effects of the black tea polyphenol, theaflavin-3,3′-digallate (TFDG), on osteoclast and MMP activity are unknown. Therefore, we examined whether TFDG and EGCG affect MMP activity and osteoclast formation and differentiation in vitro. TFDG or EGCG (10 and 100 μM) was added to cultures of rat osteoclast precursors cells and mature osteoclasts. Numbers of multinucleated osteoclasts and actin rings decreased in polyphenol-treated cultures relative to control cultures. MMP-2 and MMP-9 activities were lower in TFDG- and EGCG-treated rat osteoclast precursor cells than in control cultures. MMP-9 mRNA levels declined significantly in TFDG-treated osteoclasts in comparison to control osteoclasts. TFDG and EGCG inhibited the formation and differentiation of osteoclasts via inhibition of MMPs. TFDG may suppress actin ring formation more effectively than EGCG. Thus, TFDG and EGCG may be suitable agents or lead compounds for the treatment of bone resorption diseases.

Nitric oxide synthase (NOS) is a key regulator of angiogenesis and embryogenesis in the mammalian reproductive process. Here, we attempted to clarify the expression and localization of inducible and endothelial NOS (iNOS and eNOS) in the developing rabbit placenta. Real-time RT-PCR analysis indicated that iNOS mRNA was significantly upregulated during pregnancy, and then significantly decreased after d18 (completion of the placentation period). The eNOS mRNA was also enhanced in the pregnant uteri and gradually decreased near the term of pregnancy. Western blot analysis also showed elevation of the iNOS and eNOS protein levels during the course of pregnancy. Immunohistochemical study revealed distinct localizations of iNOS along the radial arteries and eNOS at the spiral arteries and arterial sinuses in the developing placenta. This may reflect that iNOS and eNOS participate in pregnancy success through placentation-specific vascular formation and by supporting adequate blood circulation in the rabbit placenta.

A gigantic earthquake with a magnitude of 9.0, the maximum ever recorded in Japan, struck the Tohoku region of Japan on 11 March, 2011. As a result, as many as 745 reservoirs in Fukushima prefecture were damaged. The failure of the earth-fill dam at the Fujinuma reservoir in Fukushima prefecture resulted in eight deaths in a village downstream. This was only the second such dam to fail completely in the recorded history of Japan, the first being Mannou Lake dam. The failure was caused by the Ansei Nankai earthquake in 1854. According to official records, of the 210,000 reservoirs in Japan, at least 20,000 dams are vulnerable to future earthquakes. Therefore, it is imperative that the failure mechanism of the Fujinuma reservoir be understood. As such, we developed several theories to explain what happened. Adherence to recommendations made in this report will reduce the potential for damage in future catastrophic events.

We present an intensity based credit rating migration model and execute empirical analyses on forecasting the number of downgrades in some credit portfolios. The framework of the model is based on so-called top-down approach. We firstly model economy-wide rating migration intensity with a self-exciting stochastic process. Next, we characterize the downgrade intensity for the underlying sub-portfolio with some thinning model specified by the distribution of credit ratings in the sub-portfolio. The results of empirical analyses indicate that the model is to some extent consistent with downgrade data of Japanese firms in a sample period.

福島第一原子力発電所から放出された放射性セシウム及びヨウ素の土壌深部への移行実態を明らかにすることは、放射性物質の農作物への移行を調べる上で重要である。本研究では、土壌特性の異なる水田、畑地、果樹園、森林において放射性セシウム及びヨウ素の深度分布を調べた。すべての試料において表層から6cmまでに90%以上の放射性セシウムが存在していることが分かった。畑、果樹園、森林の表層試料(0-2cm)には試料間に大きなばらつきは見られなかったが、水田試料には10倍以上の違いが見られた。また深部への移行は畑試料で大きく、水田試料で小さい傾向が見られた。これは畑土壌に比べ水田土壌の透水性が低いため土壌表面で水平方向の移動が大きくなったことを反映したものと考えられる。

アサガオ(Ipomoea nil または,Pharbitis nil)の speckled 変異により淡黄色花を咲かせる 54Y 系統と c-1 変異により白花を持つ 78WWc-1 系統の F1 並びに F2 植物について,花弁に含まれるアントシアニンとその関連化合物を解析した.speckled 変異が優性の遺伝因子である speckled-activator と共存すると,花弁に吹掛絞が現れる.Speckled と C-1 遺伝子座は強く連鎖しており,78WWc-1 系統にのみ speckled-activator が存在する.このため,F1 植物は赤紫花を咲かせ,F2 では赤紫花,白花,吹掛絞(淡黄色地に赤紫の斑点模様)の花,淡黄色花の植物が 8 : 4 : 3 : 1 の割合で分離する.解析の結果,F1 と F2 の赤紫花,さらに吹掛絞の斑点部分には同じアントシアニンが含まれていた.いずれもウェディングベルアントシアニン(WBA)が主要な色素であり,その前駆体など 9 種のアントシアニン(ペラルゴニジン誘導体)も蓄積していた.一方,54Y と淡黄色花の F2,さらに吹掛絞の淡黄の地色部分では,カルコノナリンゲニン 2'-グルコシドが主要なフラボノイドとして検出されたほか,少量のカフェ酸とオーロシジン 4-グルコシドやクロロゲン酸もみいだされた.また,78WWc-1 と白花の F2 には,クロロゲン酸とカフェ酸が存在した.これらの結果から,speckled 変異と c-1 変異を持つアサガオでは,それぞれカルコン異性化酵素(CHI)とカルコン合成酵素(CHS)が触媒する反応過程でアントシアニン色素生合成が遮断されていることが強く示唆された.また,吹掛絞の斑点部分では,完全に色素生合成系が活性化していると思われた.さらに,F2 の赤紫花と吹掛絞の斑点部分に含まれるアントシアニン構成が個体毎に異なることから,これまで報告されていない未知の遺伝的背景が WBA の生合成を制御している可能性が高い.

権力を,権利や意思という概念と関連させて考察するためには,社会的決定関数という社会装置に基づくのがよい.社会的決定関数は,社会状態を,社会にたいして開かれた機会集合から人々の選好の組を参照しつつ,一義的に導き出す手続きであり,その機能に着目すれば制度と等置できる.権力とは,社会的決定の中に自らの意思を貫徹する能力と理解できるから,この関数の入力の一つである意思と出力である社会的決定とを比較することにより,その記述を与えることができる.たとえば,他者の意思がどんな配置になっていようと特定の社会状態を帰結できる行為者は一定の権力を有しているといえよう.ある個人の選好と社会的決定の一致の度合から,われわれは,狭義の権力,権限,権利という次第に強さを増す一連の権力概念を提案した.ところでこの入出力の対応は制度である社会的決定関数によって定まっているから,権力は制度の属性として記述を与えられることになる.それゆえ,権力は制定の一部分である.それは,社会的決定関数が,幾分かは個別の個人行為者による部分的な決定へと分解可能なものであることに基づいていて,われわれはそこに権力関係を読み取るのである.権力の布置は,したがって,人々の選好の布置に基づいているわけではなく,社会的決定関数の関数形の一部であり,これを選好の布置に依存すると考えるのはいわゆるカテゴリー錯誤を犯すものである.権力関係はまた社会的決定関数のもつ形式的特性によって制約をうけるし,逆に権力関係のあり方が社会的決定関数に制約を加えることもある.その例としてSenのLiberal Paradoxと戦略的操作の可能性が挙げられる.

In 1962, Kempe first described a clinical picture of children who have received physical abuse from their parents or foster parents as a battered child syndrome.We recently experienced a case of the battered child syndrome with oral candidiasis and mandibular fracture. A female infant of 1 year and 1 month post partum was referred to our hospital because of malnutrition and multiple unexplained trauma. Radiological studies revealed subdural hematoma and mandibular fracture, while the intraoral examination revealed extensive pseudomembrane and severe stomatitis.The patient was suspected of battered child syndrome and hospitalized so as to isolate from her mother. General management subsequently performed including chemotherapy, fluid therapy, blood transfusion and supply of nutrients saved the patient from death.

Red peppers are used as a spice for enhancing the palatability of foods. Two major capsaicinoids, dihydrocapsaicin (DHC) and capsaicin (CAP) are responsible for up to 90% of the total pungency of pepper fruits. These capsaicinoids are known to enhance energy metabolism and thermogenesis. However, there is a little information on the effects of capsaicinoids on the lipolysis and carbohydrate metabolism. We studied the effects of DHC and CAP on plasma glucose, free fatty acid (FFA) and glycerol concentrations in rats. Male six-week-old Sprague Dawley rats were divided into the DHC, CAP and control groups. Each capsaicinoid (dose = 3 mg/kg BW/day) was subcutaneously administered to rats for 10 days. DHC increased markedly plasma glucose, FFA and glycerol concentrations on day 1-10 by 14-35%, 61-103% and 108-174%, respectively, as compared with those of the control group. CAP increased relatively plasma glucose concentrations on day 1-3 by 15-17%, as compared with the control group. However, there were no significant differences in plasma glucose concentrations on day 7-10 among three groups. On the contrary, CAP did not change plasma FFA and glycerol concentrations on day 1-3. However, CAP increased markedly plasma FFA and glycerol concentrations on day 7-10 by 54-89% and 92-98%, respectively, as compared with the control group. DHC and CAP did not change the weights of white (perirenal and periepididymal) and brown (interscapular) adipose tissues. In conclusion, the effects of capsaicinoids on plasma glucose, FFA and glycerol concentrations were relatively higher in the DHC than in the CAP, and capsaicinoids did not change the weight of white and brown adipose tissues.

北海道西部の日本海沿岸において,オジロワシとオオワシの飛行頻度に影響する気象要因を明らかにするために調査を行なった.解析した気象要素は,気圧,気温,降水量,風速,日照量および,風速の西ベクトル(西方向の風の強さ)と北ベクトル(北方向の風の強さ)で,これらとワシ類の飛行頻度とを比較した.その結果,西方向の風の強さがオジロワシ,オオワシの出現頻度に影響していた.調査地では西方向の風が吹くと海岸段丘による斜面上昇風が生じると考えられ,そのため西方向の風が強いとワシ類の出現頻度が高くなるのだと考えられる.

著者らは,入手が困難である28Mgを製造,精製し,イネの根によるMg吸収解析を行った。純アルミニウム箔に,27Al(α,3p)28Mgの核反応を試みて28Mgを製造した。カラム精製を経た後,およそ1MBqのキャリアフリーの28Mgを得ることができた。この放射性同位元素を用いてイネの根のMg吸収速度を算出した。すなわち,0.1mM及び5.0mMのMg濃度の溶液に28Mgを加え,そこに根を15から30分間浸すことで28Mgを吸収させた後,28Mgを画像として検出した。得られた画像よりイネの根から吸収されたMg量を定量した結果,溶液が5.0mMの条件下におけるMg吸収速度は,0.1mMの場合よりも6から7倍大きいことがわかった。更に,溶液のMg濃度を0.025~10mMの9段階に設定したところ,溶液のMg濃度が低い時ほど根のMg吸収能力は高まった。以上から根は溶液のMg濃度が低い場合には,Mgを能動的に吸収する機構を有することが示された。

In this study, we investigated the status of researching drug information online, and the type of Internet user who uses anonymous Web communities and websites. A Web-based cross-sectional survey of 10875 male and female Internet users aged 16 and over was conducted in March 2010. Of 10282 analyzed respondents, excluding medical professionals, about 47% reported that they had previously searched the Internet for drug information and had used online resources ranging from drug information search engines and pharmaceutical industry websites to social networking sites and Twitter. Respondents who had researched drug information online (n=4861) were analyzed by two multivariable logistic regressions. In Model 1, the use of anonymous websites associated with age (OR, 0.778; 95% CI, 0.742-0.816), referring to the reputation and the narrative of other Internet users on shopping (OR, 1.640; 95% CI, 1.450-1.855), taking a prescription drug (OR, 0.806; 95% CI, 0.705-0.922), and frequent consulting with non-professionals about medical care and health (OR, 1.613; 95% CI, 1.396-1.865). In Model 2, use of only anonymous websites was associated with age (OR, 0.753; 95% CI, 0.705-0.805), using the Internet daily (OR, 0.611; 95% CI, 0.462-0.808), taking a prescription drug (OR, 0.614; 95% CI, 0.505-0.747), and experience a side effect (OR, 0.526; 95% CI, 0.421-0.658). The analysis revealed the profiles of Internet users who researched drug information on social media sites where the information providers are anonymous and do not necessarily have adequate knowledge of medicine and online information literacy.

This study was initiated to examine the accuracy of conventional food composition table-based estimation of intakes of energy, protein, lipid and carbohydrate, in comparison with chemical analysis. For this purpose, 66 women (at the ages of 29 to 54 years) in three locations in Jeju Island, Republic of Korea, volunteered to offer 24-hour food duplicate samples. A half of them were house-wives, and the remaining half were farmers or fishers. The duplicate samples were subjected 1) to the chemical analysis for daily intake of energy, protein, lipid and carbohydrate after official methods in Korea (measured values), and 2) to the estimation of intakes of the same items taking advantage of Korean Food Composition Tables (estimated values). The two sets of the results, i.e., the measured and estimated values, were compared by paired and unpaired t-test, and linear regression analysis. The estimated values correlated closely with the measured values, irrespective of energy or the three major nutrients. A close agreement was observed for energy intake (the estimated/measured ratio of >98%), and it was also the case for protein intake (101%). Under- and over-estimation was observed, however, in regard to carbohydrate (by −8%) and lipid intake (by +24%), respectively. It was concluded that the Korean Food Composition Tables are sufficiently accurate when applied for estimation of total energy intake as well as protein intake. Cares should be taken, however, in applying the tables for estimation of lipid and carbohydrate intake, because there may be the risk of over- and under-estimation for the former and the latter, respectively.
