Short-term prognostic value of CRP in the patients with acute coronary syndrome
2000
Korean Circulation Journal
Preserved Fulltext
and Objectives Acute coronary syndrome occurs most commonly in the setting of atherosclerotic coronary artery disease, but there is little information concerning the mechanism responsible for the transition from stable to unstable coronary atherosclerotic plaque. Hypothetically, several microorganism Chlamydia pneumonia, Cytomegalovirus and Helicobacter pylori and their inflammatory reaction have been suggested as a causative motive in progression of acute coronary syndrome. Although it is

... ar whether the serum level of CRP as an inflammatory parameter is concerned with previous inflammatory change or myocardial necrosis, CRP appears to be predictive of higher risk for cardiac event in the patients with acute coronary syndrome. Our objective was to evaluate whether the inflammatory parameters CRP, ESR and WBC count are useful in predicting the short-term cardiac risk within 30 days. Materials and Method One hundred and ten patients with acute coronary syndrome were enrolled from April 1998 through August 1998. Blood samples were collected at 1st hour, 24th hour, 48th hour and 7th day and tested for CRP, ESR, WBC count and CK-MB level. Values of 323 normal were used as control. All patients were followed up for 30 days and assessed for the presence of cardiac complications. Results Peak CRP value of the patients with acute myocardial infarction 3.4 3.85 mg/dL, n 62 was higher than that of the patients with unstable angina 0.7 0.93 mg/dL, n 48, p 0.05 and controls 0.3 0.48 mg/dL, n 323, p 0.05 . Peak CRP value of patients with cardiac complication was higher than that of patients without complication 7.7 4.77 mg/dL, n 15 vs 1.3 1.74 mg/dL, n 95 p 0.05 . In multivariate analysis, peak CRP value was the only predictive parameter for development of cardiac complications in the patients with acute coronary syndrome Odds ratio 4.893, 95% confidence interval 1.212 19.756, p value 0.026 . In the high-CRP group 2 mg/dL, n 30 , the cardiac complication rate was higher than the low-CRP group 2 mg/dL, n 80 43.3% vs 2.5%, p 0.05 . Peak CRP value was correlated with age r 0.191, p 0.045 , pulse rate r 0.186, p 0.008), left ventricular ejection fraction r 0.384, p 0. 001 , peak ESR r 0.383, p 0.001 and peak WBC count r 0.307, p 0.001 , but not with peak CK-MB level. Conclusion Elevated CRP level in patients with acute coronary syndrome seems to be a valuable

With increasing concerns over the environment, biological production of cadaverine has been suggested as an alternative route to replace polyamides generated from the petroleum-based process. For an ideal bioprocess, cadaverine should be produced with high yield and productivity from various sugars abundant in biomass. However, most microorganisms are not able to efficiently metabolize other biomass-derived sugars as fast as glucose. This results in reduced growth rate and low carbon flux

... the production of desired bio-chemicals. Thus, redesign of microorganisms is necessary for utilizing those carbon sources with enhanced carbon flux and product formation. Results: In this study, we engineered Escherichia coli to produce cadaverine with rapid assimilation of galactose, a promising future feedstock. To achieve this, genes related to the metabolic pathway were maximally expressed to amplify the flux toward cadaverine production via synthetic expression cassettes consisting of predictive and quantitative genetic parts (promoters, 5′-untranslated regions, and terminators). Furthermore, the feedback inhibition of metabolic enzymes and degradation/re-uptake pathways was inactivated to robustly produce cadaverine. Finally, the resultant strain, DHK4, produced 8.80 g/L cadaverine with high yield (0.170 g/g) and productivity (0.293 g/L/h) during fed-batch fermentation, which was similar to or better than the previous glucose fermentation. Conclusions: Taken together, synthetic redesign of a microorganism with predictive and quantitative genetic parts is a prerequisite for converting sugars from abundant biomass into desired platform chemicals. This is the first report to produce cadaverine from galactose. Moreover, the yield (0.170 g/g) was the highest among engineered E. coli systems.

The phase transformations of platelet-and rod-shaped γ-Al 2 O 3 were investigated and compared to that of a commercial sample by XRD, BET surface area measurements, Transmission Electron Microscopy (TEM), solid state 27 Al-NMR and ethanol temperature programmed desorption (TPD) after sequential annealing in air up to 1100 o C. After annealing at 1100 o C, commercial γ-Al 2 O 3 mostly transformed into α-Al 2 O 3 with drastic surface area reduction (from 200 m 2 /g to 25 m 2 /g). Interestingly,

... atelet-and rod-shaped γ-Al 2 O 3 which showed exactly the same XRD patterns transformed into different phases upon the high temperature calcinations. Platelet-shaped γ-Al 2 O 3 transformed into θ-phase while the rod-shaped γ-Al 2 O 3 transformed into the δ-phase and not to the α-polymorph. Both plateletand rod-shaped aluminas retained significantly higher surface area (~60 m 2 /g) than the commercial one after the same treatment at 1100 o C. These results suggest that the phase transformation in γ-Al 2 O 3 is strongly affected by not only the crystal structure of the starting material, but its morphology as well. Ethanol TPD from platelet-and rod-shaped alumina after 1100 o C annealing, showed significantly different desorption profiles which suggest different surface characteristics even though they had almost the same surface areas. These © 2015.

After 1100 o C annealing commercial alumina showed the presence of mostly octahedral Al 3+ ions, but the other two samples displayed even higher number of tetrahedral Al 3+ ions than the initial γ-Al 2 O 3 . Morphological changes were also confirmed by TEM. All these results consistently suggest the morphology-dependent phase transformations of γ-Al 2 O 3 and the improved thermal stability of platelet-and rod-shaped γ-Al 2 O 3 in comparison to a commercial γ-Al 2 O 3 .

Sarcopenia is an age-associated decline of skeletal muscle mass and function and is known to lead to frailty, cachexia, osteoporosis, metabolic syndromes, and death. Notwithstanding the increasing incidence of sarcopenia, the molecular and cellular mechanisms driving age-related sarcopenia are not completely understood. This article reviews current definitions of sarcopenia, its potential mechanisms, and effects of exercise on sarcopenia. The pathogenesis of age-related sarcopenia is

... ial and includes myostatin, inflammatory cytokines, and mitochondria-derived problems. Especially, age-induced mitochondrial dysfunction triggers the production of reactive oxygen species (ROS) by mitochondria, impedes mitochondrial dynamics, interrupts mitophagy, and leads to mitochondria-mediated apoptosis. Aerobic exercise provides at least a partial solution to sarcopenia as it ameliorates mitochondria-derived problems, and resistance exercise strengthens muscle mass and function. Furthermore, combinations of these exercise types provide the benefits of both. Collectively, this review summarizes potential mechanisms of age-related sarcopenia and emphasizes the use of exercise as a therapeutic strategy, suggesting that combined exercise provides the most beneficial means of combating age-related sarcopenia.

The optimal treatment and appropriate follow-up period for an unruptured vertebral artery (VA) and/or posterior inferior cerebellar artery (PICA) dissection have not been established. Decisions regarding treatment of these vascular lesions are usually based on the manifesting symptoms and changes in radiologic findings during the follow-up period. We experienced a patient who had a simultaneous unruptured VA dissection and a contralateral PICA dissecting aneurysm. We did not find such a case in other literature.

... films was about 9 and 120 ⍀ cm, respectively. In addition, the critical oxygen partial pressure for the phase transition between Ir and IrO 2 was increased with increasing the deposition temperature. Thus, the phase of the deposited film, either Ir or IrO 2 , was controlled by the oxygen partial pressure and the deposition temperature. However, the formation of a thin Ir layer was detected between the IrO 2 and SiO 2 substrate. To remove this interfacial layer, the oxygen partial pressure is increased to a severe condition. And the impurity contents were below the detection limit of Auger electron spectroscopy in both Ir and IrO 2 films.

... . At the molecular level, circadian output is controlled by a molecular clock composed of positive and negative feedback loops in transcriptional and post-translational processes. CLOCK is a transcription factor known as a central component of the molecular clock feedback loops generating circadian oscillation. Although CLOCK is known to undergo multiple post-translational modifications, the knowledge of their entities remains limited. Cyclin-dependent kinase 5 (Cdk5) is a proline-directed serine-threonine kinase that is involved in various neuronal processes. Here, we report that Cdk5 is a novel regulator of CLOCK protein. Cdk5 phosphorylates CLOCK at the Thr-451 and Thr-461 residues in association with transcriptional activation of CLOCK. The Cdk5-dependent regulation of CLOCK function is mediated by alterations of its stability and subcellular distribution. These results suggest that Cdk5 is a novel regulatory component of the core molecular clock machinery.

While the risk of aneurysmal rebleeding induced by catheter cerebral angiography is a serious concern and can delay angiography for a few hours after a subarachnoid hemorrhage (SAH), current angiographic technology and techniques have been much improved. Therefore, this study investigated the risk of aneurysmal rebleeding when using a recent angiographic technique immediately after SAH. Patients with acute SAH underwent immediate catheter angiography on admission. A four-vessel examination was

... onducted using a biplane digital subtraction angiography (DSA) system that applied a low injection rate and small volume of a diluted contrast, along with appropriate control of hypertension. Intra-angiographic aneurysmal rebleeding was diagnosed in cases of extravasation of the contrast medium during angiography or increased intracranial bleeding evident in flat-panel detector computed tomography scans. In-hospital recurrent hemorrhages before definitive treatment to obliterate the ruptured aneurysm occurred in 11 of 266 patients (4.1%). Following a univariate analysis, a multivariate analysis using a logistic regression analysis revealed that modified Fisher grade 4 was a statistically significant risk factor for an in-hospital recurrent hemorrhage (p =0.032). Cerebral angiography after SAH was performed on 88 patients ≤3 hours, 74 patients between 3-6 hours, and 104 patients >6 hours. None of the time intervals showed any cases of intra-angiographic rebleeding. Moreover, even though the DSA ≤3 hours group included more patients with a poor clinical grade and modified Fisher grade 4, no case of aneurysmal rebleeding occurred during erebral angiography. Despite the high risk of aneurysmal rebleeding within a few hours after SAH, emergency cerebral angiography after SAH can be acceptable without increasing the risk of intra-angiographic rebleeding when using current angiographic techniques and equipment.
