Zn1ZnSO_4(水)1MnO_2电池的放电容量随硫酸锌浓度的增加而增加。用2摩尔的硫酸锌水溶液,二氧化锰的利用率可达65％。当放电后的电池充电时,对正极物质的X射线衍射分析表明,充电时γ-二氧化锰获得再生。以多种方法反复充放电,充放电次数可达30次以上。当充电到1.70伏,放电到0.9伏时,在1.3伏的平均电压下,电池的库仑效率约为100％,能量效率为83％,二氧化锰利用率为57％。电池放电到零伏后仍可以再充电。

In order to enhance photocatalytic water splitting rates with Pt/TiO2 powder, sufficient agitation of the biphasic medium is required to switch surficial reactions to volumetric reactions. Additionally, agitation is conducive to higher diffusion rates of the generated hydrogen and co-produced oxygen, hindering their ability to re-couple to water on Pt loaded to TiO2 powder. In order to create agitation without consuming any electricity, a novel technique utilizing Rayleigh convection was applied, and its ability to enhance photocatalytic water splitting rates was evaluated. Higher Rayleigh convective flow rates resulted in higher photocatalytic water splitting rates. Utilization of Rayleigh convection approximately doubled the photocatalytic water splitting rates, despite relatively low convective flow velocities (obtained through simple thermo-hydrodynamic simulations). The rate enhancement achieved through Rayleigh convection is a result of its ability to disperse the ultrafine Pt/TiO2 particles throughout the whole medium, leading to volumetric reactions.

Approximately 240 million people are chronically infected with hepatitis B virus(HBV),75% of whom reside in Asia. Approximately 600000 of infected patients die each year due to HBV-related diseases or hepatocellular carcinoma(HCC). The endemicity of hepatitis surface antigen in Indonesia is intermediate to high with a geographical difference. The risk of HBV infection is high in hemodialysis(HD) patients,men having sex with men,and health care workers. Occult HBV infection has been detected in various groups such as blood donors,HD patients,and HIVinfected individuals and children. The most common HBV subgenotype in Indonesia is B3 followed by C1. Various novel subgenotypes of HBV have been identified throughout Indonesia,with the novel HBV subgenotypes C6-C16 and D6 being successfully isolated. Although a number of HBV subgenotypes have been discovered in Indonesia,genotyperelated pathogenicity has not yet been elucidated in detail. Therefore,genotype-related differences in the prognosis of liver disease and their effects on treatments need to be determined. A previous study conducted in Indonesia revealed that hepatic steatosis was associated with disease progression. Pre-S2 mutations and mutations at C1638 T and T1753 V in HBV/B3 have been associated with advanced liver diseases including HCC. However,drug resistance to lamivudine,which is prominent in Indonesia,remains obscure. Although the number of studies on HBV in Indonesia has been increasing,adequate databases on HBV infection are limited. We herein provided an overview of the epidemiology and clinical characteristics of HBV infection in Indonesia.

Although liver resection is considered the most effective treatment for hepatocellular carcinoma(HCC), treatment outcomes are unsatisfactory because of the high rate of HCC recurrence. Since we reported hepatitis B e-antigen positivity and high serum hepatitis B virus(HBV) DNA concentrations are strong risk factors for HCC recurrence after curative resection of HBV-related HCC in the early 2000 s, many investigators have demonstrated the effects of viral status on HCC recurrence and post-treatment outcomes. These findings suggest controlling viral status is important to prevent HCC recurrence and improve survival after curative treatment for HBV-related HCC. Antiviral therapy after curative treatment aims to improve prognosis by preventing HCC recurrence and maintaining liver function. Therapy with interferon and nucleos(t)ide analogs may be useful for preventing HCC recurrence and improving overall survival in patients who have undergone curative resection for HBV-related HCC. In addition, reactivation of viral replication can occur after liver resection for HBV-related HCC. Antiviral therapy can be recommended for patients to prevent HBV reactivation. Nevertheless, further studies are required to establish treatment guidelines for patients with HBVrelated HCC.

Objective: Chronic kidney disease (CKD) with secondary hyperparathyroidism (SHPT) increases the risk of fragility fractures with deterioration of cortical and trabecular bone microstructure. Etelcalcetide (EC), which is used to treat SHPT, reduces parathyroid hormone (PTH) levels in the blood. However, the details of the effects of EC on the microstructure of cortical and trabecular bone remain unclear. This study investigated whether EC improved the cortical and trabecular bone microstructure in CKD model rats. Methods: Eight-week-old, male Wistar rats were fed with a 0.75% adenine diet for 4 weeks to establish the CDK model rats. At 20 weeks of age, the rats were divided into two groups (n = 9 - 11 in each group): CKD group (vehicle administration) and EC group (0.6 mg/kg, daily). EC was injected for 4 weeks starting at 20 weeks of age. After treatment, the biochemical tests, measurement of bone mineral density and bone strength, and evaluation of cortical and trabecular bone microstructure were performed. Results: Compared with the CKD group, the EC group showed significantly lower serum blood urea nitrogen, calcium, and inorganic phosphorus levels (p p p p p Conclusions: EC significantly improved cortical microstructure and cortical porosity, suppressing deterioration of cortical bone strength and loss of trabecular bone in the adenine-induced CKD model rats.

AIM： To examine the association of hepatoma-derived growth factor （HDGF） expression with the prognosis of patients with cervical cancer of the uterus （CC）. METHODS： HDGF is a unique nuclear growth factor, and it may play an important role in the development and progression of carcinoma. HDGF expression in 88 CC patients aged 23 to 76 years （median, 54 years） was analyzed by immunohistochemistry. A rabbit polyclonal antibody against the C-terminal amino acids （aa 231-240） of the human HDGF sequence was used as primary antibody at a dilution of 1：5000. This specific anti-HDGF antibody was purified using C-terminal peptide-conjugated Sepharose columns. Staining of endothelial cells in the noncancerous areas of each specimen was used as an internal positive control. Samples with more than 80% of tumor cells showing positive immunoreactivity in both the nucleus and cytoplasm were regarded as HDGF index level 2,more than 80% positive immunoreactivity in either the nucleus or cytoplasm as level 1, and less than 80% in both the nucleus and cytoplasm as level 0. The chi-square test and Fisher’s exact probability test were used to examine the relationship between HDGF expression and clinicopathologic parameters, and statistical significance was examined by the log-rank test. Multivariate analysis of factors related to survival was performed using Cox’s proportional hazards regression model. Statistical signifcance was set at P 〈 0.05. RESULTS： The five-year overall survival rate was 82.9%. Fourteen patients died due to tumors, nine of whom had tumor recurrence at 2-21 mo （median, 10 mo） after surgery. Tumor recurrence in five patients was determined at the time of the patients’ deaths. Nineteen cases were regarded as HDGF index level 0, 11 as level 1, and 58 as level 2. Patients with level 2 expression showed higher rates of histological classification of keratinized squamous cell carcinomaand adenosquamous carcinoma （44.8% of level 2 patients and 13.3% in levels 0 and 1）, de
