Hepatocellular carcinoma(HCC) is one of the most common malignancies worldwide. The main etiologies of HCC are hepatitis B virus and hepatitis C virus(HCV), and non-hepatitis B/non-hepatitis C HCC(NBNCHCC) has also been identified as an etiological factor. Although the incidence of HCV-related HCC in Japan has decreased slightly in recent years, that of NBNC-HCC has increased. The onset mechanism of NBNC-HCC, which has various etiologies, remains unclear; however, nonalcoholic steatohepatitis(NASH), a severe form of nonalcoholic fatty liver disease, is known to be an important risk factor for NBNC-HCC. Among the different advanced glycation end-products(AGEs) formed by the Maillard reaction, glyceraldehyde-derived AGEs, the predominant components of toxic AGEs(TAGE), have been associated with NASH and NBNC-HCC, including NASH-related HCC. Furthermore, the expression of the receptor for AGEs(RAGE) has been correlated with the malignant progression of HCC. Therefore, TAGE induce oxidative stress by binding with RAGE may, in turn, lead to adverse effects, such as fibrosis and malignant transformation, in hepatic stellate cells and tumor cells during NASH or NASH-related HCC progression. The aim of this review was to examine the contribution of the TAGE-RAGE axis in NASH-related HCC.

微泡可用于水处理和半导体清洗,纳米微泡可用于农业和水产业等的清洗。直径小于50μm的微泡在水中会不断缩小直至消失。此时就会产生活性氧(自由基)。利用这一现象可以清洗固体表面(半导体和纤维)。此外,普遍认为纳米泡是微泡的残留物,因其被电解质离子壳所包裹,从而,具有稳定性。在切削现场,作为冷却液的纳米微泡还能起到清洗机械的辅助作用。通过阐明纳米微泡的作用机理,有望开发一种新的清洗技术。

＜正＞ Nitrogenated amorphous carbon （a-C:N） thin films were grown on p-type silicon and quartz substrates by microwave surface wave plasma chemical vapor deposition （CVD） with various gas composition pressures （GCP）. The deposited a-C:N films were characterized for their optical, structural and electrical properties through UV/VIS/NIR spectroscopy, X-rays photoelectron spectroscopy, fourier transform infrared spectroscopy and solar simulator measurements. Optical absorption coefficient is decreased with increasing GCP. The roughness of the a-C:N is found to be very smooth （about 0.50 nm）. The film deposited at 90 Pa exhibited relatively good photovoltaic action compared to the films deposited at other GCPs.

A 69-year-old woman was diagnosed with primary aldosteronism. An enhanced computed tomography (CT) scan before surgery indicated a right adrenal tumor outside the liver. Venous sampling tests revealed unilateral overproduction of aldosterone by the right adrenal gland. Separation of the right adrenal cortex from the liver parenchyma was impractical during a laparoscopic right adrenalectomy because of the solid attachment between the two. Therefore, the existence of adrenohepatic fusion was determined. An incision was made within the right adrenal gland, leaving completely the intrahepatic adrenal tissue on the inner side of the liver, because a partial hepatectomy was not preoperatively planned, and the patient was not informed of the consent before the surgery. Pathological examination did not reveal macro- or micro-adenomas in the resected right adrenal tissue. Aldosterone to renin ratio was as high as 1380 at 22 days following the surgery. Therefore, aldosteronoma originated from the adrenohepatic fusion that remained on the inner side of the liver was highly suspected. The patient’s blood pressure was well controlled, and she did not prefer hepatectomy to be further performed, and therefore, medical therapy was continued. When planning the type of surgery (laparoscopic or open) in these potentially confusing cases, it might be necessary to consider a possibility of the unexpected intraoperative diagnosis and the immediate measures to be performed based on the diagnosis.

In this study,a large eddy simulation(LES)for fully-developed turbulent flows through a duct of regular-polygon cross-section using the immersed boundary(IB)method is *** case of the turbulent flow through the square duct,though there are some disagreements of the mean quantities related with the streamwise velocity among the present LES,the previous direct numerical simulation(DNS)and the LES without the IB method,and the present LES can reproduce the secondary flow of the DNS and *** LES result for ten types of regular-polygon duct shows that the secondary-flow speed decreases as the number of sides of the regular polygon n increases and that the secondary flow in case of the regular icosagon duct disappears like the turbulent pipe *** case of low n,the behavior of the turbulent structures near the side center is different from that near the vertex.

Gene fusions involving two of the MiT subfamily factors, such as TFE3, TFEB, TFC and MiTF, have been identified in renal cell carcinoma (RCC). Xp11.2 translocation RCC is a rare pediatric neoplasm that harbors gene fusions involving TFE3, which plays an important role in cell proliferation and survival. We herein present a case of RCC associated with Xp11.2 translocation/TFE3 gene fusion in a 14-year-old Japanese boy presenting gross hematuria and body weight loss. The tumor was characterized by histopathology, cytology and TFE3-immunohistochemistry/immunocytochemistry. Knowledge of distinctive morphological and immunostaining features of this tumor can help to accurately diagnose this rare subset of translocation associated RCC in routine pathological diagnostic procedures.
