引用

World Journal of Cardiovascular Diseases 2022年第6期12卷 304-314页

作者： Adymas Perdana Mochamad Arif Nugroho suhartono suhartono Mochamad Ali Sobirin Departement of Cardiology and Vascular Medicine Faculty of Medicine Universitas Diponegoro/Dr. Kariadi General Hospital Semarang Indonesia Department of Environmental Health Faculty of Public Health Universitas Diponegoro Semarang Indonesia

Background: Insufficient capacity for cardiac surgery results in extensive waiting time for patients requiring coronary artery bypass grafting (CABG). Previous studies have reported a consequence of an increased risk of mortality while waiting for CABG. Identification of risk factors for mortality is important in patients waiting for CABG. Objectives: To assess mortality rates and identify risk factors for mortality of patients waiting for CABG. Methods: This retrospective cohort study was done on patients waiting for elective CABG in dr. Kariadi General Hospital from January 2018 to December 2020. Identification of risk factors associated with mortality was done on patients who were waiting for CABG using logistic regression methods. Results: There were 162 patients fulfilling the criteria, with a mean waiting time for surgery of 9.8 months. While waiting for CABG surgery, 32 (19.7%) patients died of any cause. Independent risk factors for death while waiting for CABG included left ventricular ejection fraction ≤ 45% (OR 4.75;95% CI 1.76 - 12.78;p = 0.002), left main disease (OR 4.12;95% CI 1.50 - 11.27;p = 0.006), serum creatinine ≥ 1.5 mg/dl (OR 3.71;95% CI 1.41 - 9.74;p = 0.008), and a number of coronary artery disease risk factors ≥ 3 (OR 3.34;95% CI 1.24 - 8.99;p = 0.017). Conclusions: Long waiting time for CABG is associated with a high mortality rate which is influenced by left ventricular ejection fraction ≤ 45%, left main disease, serum creatinine ≥ 1.5 mg/dl, and a number of coronary arteries disease risk factors ≥ 3.

Journal of Chemistry and Chemical Engineering 2012年第4期6卷 327-335页

作者： suhartono Herri Susanto Takao Kokugan Department of Chemical Engineering Universitas Jenderal Achmad Yani Cimahi 40531 Indonesia Department of Chemical Engineering Institute Teknologi Bandung Bandung 40132 Indonesia Department of Chemical Engineering Tokyo University of Agriculture and Technology Tokyo 184-5855 Japan

With the aim to find an absorbing liquid suitable for the gas cleaning system in the application of gasification unit in a remote area, three types of oil were tested using a bubble column and a wetted wall column. Air streams containing toluene vapour with flowrates of 13.6 mL-min1 or 27.6 ***^-1 were bubbled through a 50 mL static oil in a glass tube at a temperature of 30 ℃ or 60 ℃. In experiments using the wetted wall column, air streams containing toluene were contacted with a falling thin film ofoil on the outer wall of a column with a diameter of 6.4 cm and two different contacting heights of 60 cm or 80 cm. Toluene concentrations in the air stream were adjusted in the range of 700-3000 ppm corresponding to a typical tars concentration in the producer gas. The phase equilibrium of toluene was represented as values of 1/tl of 326, 220 and 182 respectively for lubrication oil, palm oil and sunflower oil （H is Henry＇s constant with the toluene concentrations in g.L^-1 for liquid phase and ***^-3 for gas phase）. From experiments using the bubble column, it was found that the overall mass transfer coefficient （Kc, a） was in the order of 10.3 cm3-min^-1 and the overall liquid phase mass transfer coefficient （KLa）was about 10.3 ***^-1. Although lubrication oil had a slightly better absorption capacity than the other two tested oils, it had a lower mass trasfer coefficient than that of palm oil. All three proposed oils had a much better absorption capacity and absorption rate than that of water used conventionally as a scrubbing liquid in a small biomass gasification plant.

Introduction: Interleukin-2 (IL-2) is multiple which functions during an inflammatory response. Inflammation is a critical component of cancer progression. IL-10 is the most important cytokine with anti-inflammatory properties. Cancer patients typically show depression of both cellular and humoral immune functions. Aims: The objective of this experiment is to know the expression of IL-2 and IL-10 in cervical cancer. Method: Paraffin block of the tissues frozen section cervical cancer was cut in sharp and cleaned cryotome and place in glass plate that covered with poly-elysine. The immunohistochemistry stains were done with monoclonal antibody anti IL-2 and IL-10 with TSA-indirect method. The collected data were analyzed with T Test (SPSS for window 15). Result: In this study the expression of IL-2 (35.9% = moderate) is less than the expression of IL-10 (45.3% = moderate). From T Test analysis of p <= 0.153, it means that there is no significance in difference between IL-2 and IL-10. Conclusion: We indicated that the immune response plays a role in balance between cellular and humoral immunity.

Cell free supernatant containing short chain fatty acid (SCFA) resulted from fermentation of resistant starch type three (RS3) by Clostridium butyricum BCC B2571 or Eubacterium rectale DSM 17629 were investigated for their ability to inhibit proliferation and induce apoptosis of human colon cancer cell line HCT-116. HCT-116 was cultured in complete medium and after 50% confluent, incubation was continued for another 48 hours in the absence or presence cell free supernatant containing SCFA mixture at butyrate levels up to 10 mM. The study revealed that the proliferation inhibition effect was higher (>80%) on HCT-116 treated with supernatant of C. butyricum BCC B2571 than that (<70%) of HCT-116 treated with supernatant of E. rectale DSM 17629. The cells were induced to undergo apoptosis by both supernatant. The apoptosis occured through mitochondrial pathway by changing the expression of gene Bcl-2 and Bax, thus incresed the Bax/Bcl-2 ratio by more than 3.5 fold. The protein caspase-3 was increased by more than 250% in the presence of the cell free supernatant.

Objective: To compare the level of glutathione(GSH) and oxidized glutathione(GSSG),the ratio of GSH/GSSG and the concentration of albumin in plasma of patients with complicated and un-complicated falciparum ***: This research was a cross sectional study using comparison analysis with the plasma GSH and GSSG, the ratio of plasma GSH/GSSG and the concentration of plasma albumin as variables. The complicated malaria patients were obtained from Dr. Saiful Anwar Hospital Malang, whereas uncomplicated malaria patients were obtained from the Regency of Pleihari South Kalimantan. Plasma GSH and GSSG levels were determined by the spectrophotometer at the wave length of 412 nm, whereas the concentration of albumin was determined by bromocresol green method in the p H of ***: There were no significant differences between the level of plasma GSH and GSSG in complicated and uncomplicated malaria patients, as well as the ratio of plasma GSH/GSSG in the two groups(P = 0.373; P = 0.538; and P = 0.615, respectively, independent ttest). In contrast, the plasma albumin concentration in complicated malaria patients were significantly higher than uncomplicated malaria patients(P = 0.000, Mann Whitney U test).Conclusions: It can be concluded that the average of plasma GSH and GSSG level, also plasma GSH/GSSG ratio in complicated malaria are not different from uncomplicated malaria. Although plasma concentration of albumin in both groups is below the normal range,there is an increase in complicated malaria that might be as compensation of oxidative stress.
