Tissue engineering of functional cardiac muscle: molecular, structural, and electrophysiological studies. (1/79)

The primary aim of this study was to relate molecular and structural properties of in vitro reconstructed cardiac muscle with its electrophysiological function using an in vitro model system based on neonatal rat cardiac myocytes, three-dimensional polymeric scaffolds, and bioreactors. After 1 wk of cultivation, we found that engineered cardiac muscle contained a 120- to 160-microm-thick peripheral region with cardiac myocytes that were electrically connected through gap junctions and sustained macroscopically continuous impulse propagation over a distance of 5 mm. Molecular, structural, and electrophysiological properties were found to be interrelated and depended on specific model system parameters such as the tissue culture substrate, bioreactor, and culture medium. Native tissue and the best experimental group (engineered cardiac muscle cultivated using laminin-coated scaffolds, rotating bioreactors, and low-serum medium) were comparable with respect to the conduction velocity of propagated electrical impulses and spatial distribution of connexin43. Furthermore, the structural and electrophysiological properties of the engineered cardiac muscle, such as cellularity, conduction velocity, maximum signal amplitude, capture rate, and excitation threshold, were significantly improved compared with our previous studies.  (+info)

Peroxynitrite induced nitration and inactivation of myofibrillar creatine kinase in experimental heart failure. (2/79)

OBJECTIVE: Oxidative stress is implicated in the initiation and progression of congestive heart failure, but the putative reactive species and cellular targets involved remain undefined. We have previously shown that peroxynitrite (ONOO(-), an aggressive biological oxidant and nitrating agent) potently inhibits myofibrillar creatine kinase (MM-CK), a critical controller of contractility known to be impaired during heart failure. Here we hypothesized that nitration and inhibition of MM-CK participate in cardiac failure in vivo. METHODS: Heart failure was induced in rats by myocardial infarction (left coronary artery ligation) and confirmed by histological analysis at 8 weeks postinfarct (1.3+/-1.4 vs. 37.7+/-3.2% left ventricular circumference; sham control vs. CHF, n=10 each). RESULTS: Immunohistochemistry demonstrated significantly increased protein nitration in failing myocardium compared to control (optical density: 0.58+/-0.06 vs. 0.93+/-0.09, sham vs. CHF, P<0.05). Significant decreases in MM-CK activity and content were observed in failing hearts (MM-CK k(cat): 6.0+/-0.4 vs. 3.0+/-0.3 micromol/nM M-CK/min, P<0.05; 6.8+/-1.3 vs. 4.7+/-1.2% myofibrillar protein, P<0.05), with no change in myosin ATPase activity. In separate experiments, isolated rat cardiac myofibrils were exposed to ONOO(-) (2-250 microM) and enzyme studies were conducted. Identical to in vivo studies, selective reductions in MM-CK were observed at ONOO(-) concentrations as low as 2 microM (IC(50)=92.5+/-6.0 microM); myosin ATPase was unaffected with ONOO(-) concentrations as high as 250 microM. Concentration dependent nitration of MM-CK occurred and extent of nitration was statistically correlated to extent of CK inhibition (P<0.001). Immunoprecipitation of MM-CK from failing left ventricle yielded significant evidence of tyrosine nitration. CONCLUSION: These data demonstrate that cardiac ONOO(-) formation and perturbation of myofibrillar energetic controllers occur during experimental heart failure; MM-CK may be a critical cellular target in this setting.  (+info)

Production of recombinant human creatine kinase (r-hCK) isozymes by tandem repeat expression of M and B genes and characterization of r-hCK-MB. (3/79)

BACKGROUND: Serum creatine kinase-MB isoenzyme (CK-MB) is widely used as a marker of myocardial injury. We prepared recombinant human CK (r-hCK) MB isoenzyme and examined its potential for use as a control material for assay of CK-MB in serum. METHODS: cDNAs encoding CK-M and CK-B subunits were inserted into the same plasmid vector, followed by transformation of Escherichia coli. The resulting three types of CK isoenzymes were purified by conventional chromatography. RESULTS: The ratio of MB to MM to BB was 50:40:10 on the basis of CK activity. Highly purified CK-MB with a specific activity of 533 U/mg was produced in a yield of 5.7 mg/g of packed cells. Purified r-hCK-MB had the isoelectric point (pI 5.3) and molecular size (46 kDa for the subunit) of native CK-MB. Its immunoreactivity in an ELISA using antibody against native heart enzyme was similar to that of cardiac CK-MB. The r-hCK-MB retained >90% activity for at least 4 months at 11 degrees C in a delipidated serum matrix in a liquid form at a concentration of 118 U/L. CONCLUSIONS: r-hCK-MB shows key properties of the native cardiac isoenzyme and may be useful as a control and calibrator for serum assays of CK-MB.  (+info)

Enhanced expression of the alpha 7 beta 1 integrin reduces muscular dystrophy and restores viability in dystrophic mice. (4/79)

Muscle fibers attach to laminin in the basal lamina using two distinct mechanisms: the dystrophin glycoprotein complex and the alpha 7 beta 1 integrin. Defects in these linkage systems result in Duchenne muscular dystrophy (DMD), alpha 2 laminin congenital muscular dystrophy, sarcoglycan-related muscular dystrophy, and alpha 7 integrin congenital muscular dystrophy. Therefore, the molecular continuity between the extracellular matrix and cell cytoskeleton is essential for the structural and functional integrity of skeletal muscle. To test whether the alpha 7 beta 1 integrin can compensate for the absence of dystrophin, we expressed the rat alpha 7 chain in mdx/utr(-/-) mice that lack both dystrophin and utrophin. These mice develop a severe muscular dystrophy highly akin to that in DMD, and they also die prematurely. Using the muscle creatine kinase promoter, expression of the alpha 7BX2 integrin chain was increased 2.0-2.3-fold in mdx/utr(-/-) mice. Concomitant with the increase in the alpha 7 chain, its heterodimeric partner, beta 1D, was also increased in the transgenic animals. Transgenic expression of the alpha 7BX2 chain in the mdx/utr(-/-) mice extended their longevity by threefold, reduced kyphosis and the development of muscle disease, and maintained mobility and the structure of the neuromuscular junction. Thus, bolstering alpha 7 beta 1 integrin-mediated association of muscle cells with the extracellular matrix alleviates many of the symptoms of disease observed in mdx/utr(-/-) mice and compensates for the absence of the dystrophin- and utrophin-mediated linkage systems. This suggests that enhanced expression of the alpha 7 beta 1 integrin may provide a novel approach to treat DMD and other muscle diseases that arise due to defects in the dystrophin glycoprotein complex. A video that contrasts kyphosis, gait, joint contractures, and mobility in mdx/utr(-/-) and alpha 7BX2-mdx/utr(-/-) mice can be accessed at http://www.jcb.org/cgi/content/full/152/6/1207.  (+info)

Muscle-specific overexpression of the adenovirus primary receptor CAR overcomes low efficiency of gene transfer to mature skeletal muscle. (5/79)

Significant levels of adenovirus (Ad)-mediated gene transfer occur only in immature muscle or in regenerating muscle, indicating that a developmentally regulated event plays a major role in limiting transgene expression in mature skeletal muscle. We have previously shown that in developing mouse muscle, expression of the primary Ad receptor CAR is severely downregulated during muscle maturation. To evaluate how global expression of CAR throughout muscle affects Ad vector (AdV)-mediated gene transfer into mature skeletal muscle, we produced transgenic mice that express the CAR cDNA under the control of the muscle-specific creatine kinase promoter. Five-month-old transgenic mice were compared to their nontransgenic littermates for their susceptibility to AdV transduction. In CAR transgenics that had been injected in the tibialis anterior muscle with AdVCMVlacZ, increased gene transfer was demonstrated by the increase in the number of transduced muscle fibers (433 +/- 121 in transgenic mice versus 8 +/- 4 in nontransgenic littermates) as well as the 25-fold increase in overall beta-galactosidase activity. Even when the reporter gene was driven by a more efficient promoter (the cytomegalovirus enhancer-chicken beta-actin gene promoter), differential transducibility was still evident (893 +/- 149 versus 153 +/- 30 fibers; P < 0.001). Furthermore, a fivefold decrease in the titer of injected AdV still resulted in significant transduction of muscle (253 +/- 130 versus 14 +/- 4 fibers). The dramatic enhancement in AdV-mediated gene transfer to mature skeletal muscle that is observed in the CAR transgenics indicates that prior modulation of the level of CAR expression can overcome the poor AdV transducibility of mature skeletal muscle and significant transduction can be obtained at low titers of AdV.  (+info)

Overexpression of the LAR (leukocyte antigen-related) protein-tyrosine phosphatase in muscle causes insulin resistance. (6/79)

Previous reports indicate that the expression and/or activity of the protein-tyrosine phosphatase (PTP) LAR are increased in insulin-responsive tissues of obese, insulin-resistant humans and rodents, but it is not known whether these alterations contribute to the pathogenesis of insulin resistance. To address this question, we generated transgenic mice that overexpress human LAR, specifically in muscle, to levels comparable to those reported in insulin-resistant humans. In LAR-transgenic mice, fasting plasma insulin was increased 2.5-fold compared with wild-type controls, whereas fasting glucose was normal. Whole-body glucose disposal and glucose uptake into muscle in vivo were reduced by 39-50%. Insulin injection resulted in normal tyrosyl phosphorylation of the insulin receptor and insulin receptor substrate 1 (IRS-1) in muscle of transgenic mice. However, phosphorylation of IRS-2 was reduced by 62%, PI3' kinase activity associated with phosphotyrosine, IRS-1, or IRS-2 was reduced by 34-57%, and association of p85alpha with both IRS proteins was reduced by 39-52%. Thus, overexpression of LAR in muscle causes whole-body insulin resistance, most likely due to dephosphorylation of specific regulatory phosphotyrosines on IRS proteins. Our data suggest that increased expression and/or activity of LAR or related PTPs in insulin target tissues of obese humans may contribute to the pathogenesis of insulin resistance.  (+info)

Screening of dystrophin gene deletions in Egyptian patients with DMD/BMD muscular dystrophies. (7/79)

Duchenne muscular dystrophy (DMD) and Becker muscular dystrophy (BMD) are allelic disorders caused by mutations within the dystrophin gene. Our study has identified 100 Egyptian families collected from the Human Genetics Clinic, National Research Center, Cairo. All cases were subjected to complete clinical evaluation pedigree analysis, electromyography studies, estimation of serum creatine phosphokinase enzyme (CPK) levels and DNA analysis. Multiplex PCR using 18 pairs of specific primers were used for screening of deletion mutations within the dystrophin gene. A frequency of 55% among the families. Sixty per cent of detected deletions involved multiple exons spanning the major or the minor hot spot of the dystrophin gene. The remainder 40% which mainly involved exon 45. Comparing these findings with frequencies of other countries it was found that our figures fall within the reported range of 40%- distribution of deletions in our study and other different studies was variable and specific ethnic differences do not apparently account for specific deletions. In addition this study concluded that employment of the 18 exon analysis is a cost effective and a highly accurate (97% to launch a nationwide program.  (+info)

Electrophoresis of creatine kinase isoforms: a highly sensitive fluorescence scanning method. (8/79)

OBJECTIVE: To develop an agarose electrophoretic method for creatine kinase (CK) isoforms, using highly sensitive fluorescence scanning. METHODS: A discontinuous buffer system was used. Electrophoresis on agarose gel was performed under constant current and low voltage. CK isoforms were separated within 30 minutes and detected by fluorescence scanning. RESULTS: There were no significant differences when the activities of CK-MM were between 853.0 U/L and 14.0 U/L and those of CK-MB between 152.0 U/L and 2.4 U/L. The detection limits of stain method for CK-MM and CK-MB isoforms were 36.0 U/L and 12.3 U/L, respectively; while those of fluorescence method were 12.0 U/L and 2.1 U/L. The experimental results showed good precision for CK-MM isoforms, as well for CK-MB isoforms and isoenzymes. CONCLUSION: An agarose electrophoretic method has been developed to measure CK isoenzymes and isoforms clinically. This method is rapid, simple, sensitive, highly reproducible and inexpensive. It is suitable for general laboratories.  (+info)

AU - Leyh, Thomas S.. AU - Reed, George H.. PY - 1980/1/1. Y1 - 1980/1/1. N2 - Several conformationally restricted analogues of creatine have been both synthesized and examined as potential substrates or inhibitors of rabbit muscle creatine kinase (EC 2.7.3.2). When an asymmetric center was included in a creatine analogue in the position α to the carboxyl group, the enzyme had a pronounced preference for the R enantiomer. Thus, whereas (R)-N-amidinoazetidine-2-carboxylic acid (7) has been shown to be a good substrate (Ks = 72 mM, Km = 39 mM, and Vmax = 29% relative to that of creatine) for creatine kinase, the corresponding S enantiomer 6 showed only barely detectable reactivity (Fmax(rel) ≪ 1%). When the corresponding ring-opened analogue, N-methyl-N-amidino-alanine, was examined as a substrate, ...
N-linked glycosylation has a profound effect on the proper folding, oligomerization and stability of glycoproteins. These glycans impart many properties to proteins that may be important for their proper functioning, besides having a tendency to exert a chaperone-like effect on them. Certain glycosylation sites in a protein however, are more important than other sites for their function and stability. It has been observed that some N-glycosylation sites are conserved over families of glycoproteins over evolution, one such being the tyrosinase related protein family. The role of these conserved N-glycosylation sites in their trafficking, sorting, stability and activity has been examined here. By scrutinizing the different glycosylation sites on this family of glycoproteins it was inferred that different sites in the same family of polypeptides can perform distinct functions and conserved sites across the paralogues may perform diverse functions.. ...

Muscle creatine kinase (CKm) activity maintains energetic homeostasis as variations in energy requirements dictate that ATP be readily available. Recent studies suggest that CKm activity is altered during aging. Proteomic analyses have shown that CKm is 3-nitrotyrosine (3-NT) modified and carbonylated in aged rodent skeletal muscle. However, it remains unknown if these modifications affect its structure and activity. To address this we characterized oxidatively modified CKm from the quadriceps of young, middle-aged, and aged mice. Our data ...
Two experiments were performed, in which male Wistar Walker 256 tumor-bearing rats were inoculated with 4 x 10(7) tumor cells subcutaneously and received either creatine (300 mg/kg body weight/day; CR) or placebo (water; PL) supplementation via intragastric gavage. In experiment 1, 50 rats were given PL (n = 22) or CR (n = 22) and a non-supplemented, non-inoculated group served as control CT (n = 6), for 40 days, and the survival rate and tumor mass were assessed. In experiment 2, 25 rats were given CR or PL for 15 days and sacrificed for biochemical analysis. Again, a non-supplemented, non-inoculated group served as control (CT; n = 6). Tumor and muscle creatine kinase (CK) activity and total creatine content, acidosis, inflammatory cytokines, and antioxidant capacity were assessed. Tumor growth was significantly reduced by approximately 30 % in CR when compared with PL (p = 0.03), although the survival rate was not significantly different between CR and PL (p = 0.65).

Okay, heres the problem. Creatine isnt meant to be rolling around in plasma. Creatine isnt stored in your blood vessels, nor has it any purpouse there. Creatine is the main fuel for Creatine Phosphate, which is found on your muscles. This CP provides the first seconds of maximal force production with ATP, it only lasts but a mere minute and under. It has nothing to do with protein intake. You get creatine from meats, and it actually recovers quite well after the performance. The reason for creatine use is to increase the capacity the muscle can hold and use creatine. It also ties water in some sources, which might cause bulking. Muscle creatine levels wont drop unless you are actually exercising. Secondly, I wouldnt recommend a use for creatine over 5g-10g per day unless its a loading phase (up to 20g a day), but the loading phase shouldnt last but a week or thereabouts ...

Okay, sure, but with me you didnt get sore but your lifts went up, your body fat percentage went down, and youve been injury free. But its easy to mistake soreness with results, and effort with utility. Just because something grinds you down or was hard or made you sore doesnt mean its going to make you better ...

Xenoestrogens such as alkylphenols and the structurally related plastic byproduct bisphenol A have recently been shown to act potently via nongenomic signaling pathways and the membrane version of estrogen receptor-α. Though the responses to these compounds are typically measured individually, they usually contaminate organisms that already have endogenous estrogens present. Therefore, we used quantitative medium-throughput screening assays to measure the effects of physiologic estrogens in combination with these xenoestrogens. We studied the effects of low concentrations of endogenous estrogens (estradiol, estriol, and estrone) at 10 pM (representing pre-development levels), and 1 nM (representing higher cycle-dependent and pregnancy levels) in combinations with the same levels of xenoestrogens in GH3/B6/F10 pituitary cells. These levels of xenoestrogens represent extremely low contamination levels. We monitored calcium entry into cells using Fura-2 fluorescence imaging of single cells. Prolactin
Creatine is one of the most popular and widely researched natural supplements. The majority of studies have focused on the effects of creatine monohydrate on performance and health; however, many other forms of creatine exist and are commercially available in the sports nutrition/supplement market. Regardless of the form, supplementation with creatine has regularly shown to increase strength, fat free mass, and muscle morphology with concurrent heavy resistance training more than resistance training alone. Creatine may be of benefit in other modes of exercise such as high-intensity sprints or endurance training. However, it appears that the effects of creatine diminish as the length of time spent exercising increases. Even though not all individuals respond similarly to creatine supplementation, it is generally accepted that its supplementation increases creatine storage and promotes a faster regeneration of adenosine triphosphate between high intensity exercises. These improved outcomes will increase

CK : Creatine kinase (CK) activity is greatest in striated muscle, heart tissue, and brain. The determination of CK activity is a proven tool in the investigation of skeletal muscle disease (muscular dystrophy) and is also useful in the diagnosis of myocardial infarction (MI) and cerebrovascular accidents. Increased levels of CK also can be found in viral myositis, polymyositis, and hypothyroidism.   Following injury to the myocardium, such as occurs in acute MI, CK is released from the damaged myocardial cells. A rise in the CK activity can be found 4 to 8 hours after an infarction. CK activity reaches a maximum after 12 to 24 hours and then falls back to the normal range after 3 to 4 days.
In the dog, creatine kinase (CK) is mostly present in the skeletal muscles, myocardium, brain and intestine. The MM isoenzyme predominates in muscles and myocardium. In plasma, reference values depend on the technique used and CK-MB accounts for about 30-45% of total CK activity. Sex has no influence on plasma CK activity, which is higher in young dogs than in adults. Plasma CK is elevated after physical exercise. After its release from the cells, CK reaches the plasma mostly via the lymphatic route and then remains in the plasma compartment. It is rapidly cleared with a half-life of about 2 hours. Muscle diseases are the main source of plasma CK elevations: inherited myopathies, malignant hyperthermia, hypothyroidism, vitamin E-selenium deficiency, prolonged decubitus, intramuscular injections, surgery, etc. Plasma CK is also increased in experimental myocardial infarction, for which the dog is an interesting model, allowing quantification of the damage by measuring the total CK activity ...

INTRODUCTION. Trauma of diverse origins is a common reason for presentation of pets for treatment. It is often difficult clinically to objectively quantify the severity of any trauma suffered by an animal. One approach is to measure changes in the various serum constituents that are known to alter in response to trauma or inflammation. Creatine kinase (CK) is an enzyme found predominantly in skeletal muscle and significantly elevated serum activity is largely associated with muscle damage. It is an extremely sensitive indicator of muscle damage, but is not specific as to cause14,27. Serum elevations in dogs are associated with cell membrane leakage and will therefore be seen in any condition associated with muscular inflammation, necrosis or degeneration. Peak serum activity is expected between 3 and 12 hours after muscular insult and the elevation is roughly proportional to the amount of muscle tissue involved1,5,27.It is also possible to quantify the mass of muscle damage if the changes in CK ...

Creatine phosphate then chemically "donates" its phosphate group to aid in the regeneration of ATP. Ultimately, the more creatine that is loaded into the muscle cell, the more ATP that is available to fuel muscle cell contractions. As I stated above, creatine requires a carrier hormone to facilitate its entry into the muscle cell. Insulin (the blood sugar-regulating hormone) is also the hormone responsible for enabling creatine to enter the cell. In the absence of insulin, creatine will not reach its target tissue and thus will not exert its muscle-potentiating effects.. Many supplement companies have taken this important fact and have designed creatine formulations that contain astronomical amounts of simple sugars under the guise that, without these sugars, creatine could not be properly absorbed. It is because of these sugar-laced creatine formulations that many users are getting too much insulin release and are gaining significant amounts of unwanted body fat. Likewise, individuals who are ...

Creatine kinase (CK) isoenzymes are essential for storing, buffering and intracellular transport of "energy-rich" phosphate compounds in tissues with fluctuating high energy demand such as muscle, brain and other tissues and cells where Creatine Kinase CK is expressed. Using dividing HeLa cells, we report here for the first time that GM130 and Creatine Kinase BB isoenzyme BB-CK co-localize specifically in a transient fashion during early prophase of mitosis, when GM130 plays an important role in Golgi fragmentation that starts also at early prophase. These data may shed new light on CK BB Isoenzyme BB-CK function for energy provision for Golgi-fragmentation that is initiated by cell signalling cascades in the early phases of mitosis. source ...
Creatine is a substance that is naturally produced by the human body from amino acids. The production of creatine occurs primarily in the kidneys and the liver, but 95% of it is found in the skeletal muscles. It is transported by the bloodstream to the muscles and is important in muscle activity.. Creatine kinase is an enzyme produced by various tissues that catalyzes the conversion of creatine in muscle activity. In clinical diagnostic testing, creatine kinase levels in the blood are measured as part diagnosis of a number of illnesses. These include acute renal failure (breakdown of kidney function), myocardial infarction (heart attack), muscular dystrophy, and rhabdomyolysis (severe muscle breakdown).. Types Of Creatine Kinase. There are two main recognized types of creatine kinase, type B and type M. The B and M stand respectively for "brain" and "muscle." Three isoenzymes of creatine kinase are recognized, CK-MM, CK-BB and CK-MB; these are formed from the basic B and M type of creatine ...
The significance of elevated levels of the MB isomer of creatine kinase (CK-MB) when creatine kinase (CK) level is normal was studied in 400 patients with suspected acute myocardial infarction (AMI). In 350 patients both CK and CK-MB were elevated (group 1), in 21 only CK-MB was elevated (group 2), in 24 neither enzyme was elevated (group 3) and in 5 only CK was elevated (group 4). In 57% of patients in group 2 the CK level was doubled, with a characteristic enzyme curve, within the normal range, suggesting that an increase in CK had been missed because arbitrary definitions of normal were used. The median CK increase (60 IU/liter) in group 2 was greater than that in group 3 (23 IU/liter) (p | 0.001). Patients in group 1 with small AMIs had a relative increase in CK similar to that in group 2. However, patients in group 2 had a lower baseline CK level so that peak CK did not become abnormally high despite a 5-fold increase in some patients. In patients in group 1 with small AMIs, CK was elevated in

Results: sixty-seven of 71 renal units completed the survey. Although terminology varied, there was general acceptance of the role of CKM. Only 52% of units were able to quantify the number of CKM patients. A wide range reflected varied interpretation of the designation CKM by both staff and patients. It is used to characterise a future treatment option as well as non-dialysis care for end-stage kidney failure (i.e. a disease state equivalent to being on dialysis). The number of patients in the latter group on CKM was relatively small (median 8, interquartile range 4.5-22). Patients expectations of CKM and dialysis were strongly influenced by renal staff. In a minority of units, CKM was not discussed. When discussed, often only limited information about illness progression was provided. Staff wanted more research into the relative benefits of CKM versus dialysis. There was almost universal support for an observational methodology and a quarter would definitely be willing to participate in a ...

Creatine is an amino acid that occurs in vertebrate tissues and in urine. In muscle tissue, creatine generally occurs as phosphocreatine. Creatine is excreted as creatinine in the urine. Creatine functions as part of the cells energy shuttle. The high energy phosphate group of ATP is transferred to creatine to form phosphocreatine in the following reaction: Cr + ATP <-> PCr + ADP. This reaction is reversibly catalyzed by creatine kinase. In the animal body creatine is synthesized mainly in the liver by the use of parts from three different amino acids - arginine, glycine, and methionine. 95% of it is later stored in the skeletal muscles, with the rest in the brain, heart, testes ...
Hypertension remains the main risk factor for cardiovascular death. Environmental and biological factors are known to contribute to the condition, and circulating creatine kinase was reported to be the main predictor of blood pressure in the general population. This was proposed to be because of high resistance artery creatine kinase-BB rapidly regenerating ATP for vascular contractility. Therefore, we assessed whether creatine kinase isoenzyme mRNA levels in human resistance arteries are associated with blood pressure. We isolated resistance-sized arteries from omental fat donated by consecutive women undergoing uterine fibroid surgery. Blood pressure was measured in the sitting position. Vessels of 13 women were included, 6 normotensive and 7 hypertensive, mean age 42.9 years (SE, 1.6) and mean systolic/diastolic blood pressure, 144.8 (8.0)/86.5 (4.3) mm Hg.
