| 1 | Liquid-Liquid Equilibria of Water + Butyric Acid + Nonanol Ternary System显示文摘Liquid-liquid equilibrium (LLE) data for the water + butyric acid + nonanol system have been determined experimentally at the temperatures of 298.15 K, 308.15 K and 318.15 K. Tie-line compositions were correlated by Othmer-Tobias method. The universal quasichemical functional group activity coefficient (UNIFAC) and modified UNIFAC methods were used to predict the phase equilibrium in the system using the interaction parameters between CH3, CH2, COOH, OH and H2O functional groups. Distribution coefficients and separation factors were evaluated for the immiscibility region. | S.Ismail Kirbaslar Sema Yüksel Erol Ince Ismail Boz | 2004 | Chinese Journal of Chemical Engineering2004，12，5： | 2 |
| 7 | Iatrogenic scleroderma renal crisis:A case report and mini literature review for renal crisis显示文摘Background:Systemic sclerosis is a connective tissue disease characterized by fibrosis of the skin and organs,marked changes in microvascular structure,cellular and humoral immune disorders.Renal involvement is more frequent and mainly characterized by moderate proteinuria,elevated serum creatinine levels,and hypertension.The most common kidney involvement in SSc is scleroderma renal crisis(SRC)that is fatal without prompt intervention.Case report:A 52-year-old Caucasian male with known diffuse cutaneous systemic sclerosis was hospitalized with communityacquired pneumonia.On the fifth day after appropriate antibiotic therapy and 60 mg/day methylprednisolone,decreased urine output,arterial hypertension,decreased renal function and pulmonary edema developed.The patient was diagnosed with a scleroderma renal crisis.Emergency hemodialysis was applied to the patient,and captopril 6×25 mg/day and nifedipine 2*60 mg/day treatment were given.He received a routine hemodialysis program for about three months.The hemodialysis program was terminated when the patient’s urine quality and quantity increased.Conclusions:SRC,characterized by malignant hypertension,azotemia,microangiopathic hemolytic anemia,and kidney failure,is one of the most important complications of systemic sclerosis with a poor prognosis without prompt intervention.Steroid use is one of the important risk factors that precipitate SRC development.With angiotensin-converting enzyme inhibitors,survival increased after SRC,the need for dialysis decreased,and usually allowed the discontinuation of dialysis treatment within about 6-18 months.Suspicion of SRC in the presence of the above-mentioned findings in patients with a diagnosis or suspected systemic sclerosis can be considered the most important treatment step. | Gülsah Boz Samet Karahan Nurdan Yüksek | 2021 | Discussion of Clinical Cases2021，8，3： | 0 |
