Stochastic simulations confirm the existence of bifurcation values of the control parameters bounding a domain in which sustained oscillations occur. The effect of noise diminishes as the number of molecules increases. Only when the maximum numbers of molecules of mRNA and protein become smaller than a few tens does noise begin to obliterate the circadian rhythm. The robustness of circadian rhythms with respect to molecular noise is enhanced when the rate of binding of the repressor molecule to the gene promoter increases [128]. Conditions that enhance the resistance of genetic oscillators to random fluctuations have been investigated [130].

Primary haemostasis Acute sclerosing is generally performed during the first endoscopic examination. The rate of haemostasis is 70-95(-100)%. The frequency of (early and late) recurrent bleeding has been reduced to 30-50%, most effectively after several months when all varices have been obliterated. Nevertheless, an annual risk of recurrent bleeding of 10-20% remains due to newly formed varices, especially in the stomach fundus. Inpatient mortality is about 20%. However, more ways are being found to improve the life expectancy of the patient. 

Such destruction continues at a rate of more than 20,000 square kilometers per year. If current trends continue, many of the world s rain forests will be severely reduced or even obliterated in the next few years. The fundamental question— What are the long-term consequences of the destruction of tropical rain forests —remains unanswered. 

The objective of both EIS and EBL in prevention of rebleeding is the obliteration of esophageal varices. The majority of rebleeding occurs in the interval between the primary endoscopic session and the time to complete obliteration. Therefore the patient should have repeat endoscopy with either EIS or EBL every 2 weeks until no further varices are identified. After this is achieved, repeat exams at 3 and 6 months are appropriate. The rebleeding rate after EBL is less than EIS, 27% versus 45%. ...

The positive correlation (r = + 0.85) between 5 C and 5 0 values (Fig. 22) of the eogenetic Lunde carbonates may be related to relatively rapid near-surface precipitation caused by evaporation and CO2 degassing (e.g. Salomons et al., 1978 Schlesinger, 1985 Salomons Mook, 1986 Spotl Wright, 1992), which increases the enrichment of C and 0 isotopes. However, it is believed that at depths of a decimetre the evaporation rate is substantially reduced, and there is thus very little opportunity for significant 0 enrichment in soil water before the next rainfall causes sufficient infiltration to obliterate this effect (Hellwig, 1973). 

The major aims of interventional procedures for portal hypertension are prophylactic and emergent treatment of variceal bleeding, control of hepatic encephalopathy, and treatment of refractory ascites. Hypersplenism associated with hematological disorder is an additional clinical problem in patients with portal hypertension. At present, the main primary embolotherapies available for portal hypertension are balloon-occluded retrograde transvenous obliteration (BRTO) and partial splenic embolization (PSE). In Japan, BRTO has recently been applied for gastric varices instead of either endoscopic treatment or transhepatic intrahepatic portosystemic shunt (TIPS) procedure, and numerous studies have reported that this method has an excellent success rate. Its efficacy for control of hepatic encephalopathy has also been demonstrated.
