Advanced oxidation of a pulp mill bleaching wastewater.

The degradation, by several advanced oxidation reactions, of a pulp mill ECF bleaching effluent, was studied. The initial biodegradability of the organic matter present in the effluent, estimated as the BOD5/COD, was low (0.3).

Iron-binding catechols oxidating lignin and chlorolignin.

Iron-chelating low-molecular-weight compounds or catecholate siderophores have been suggested to be involved in wood biodegradation. To help in understanding the mechanism involved in the enzyme-like activity of catecholate siderophores, the oxidative properties of 2,3-dihydroxybenzoic acid (DHBA) and 3, 4-dihydroxyphenylacetic acid (DHPAA) chelated with iron were studied. The pH and catechol/Fe(III) ratios were optimized for o-dianisidine oxidation, obtaining a maximum at pH 7.

Health promotion. Beating the bands?

A survey of health authorities in England to establish GPs' health promotion activities found that anti-smoking and heart disease prevention were the most common initiatives. Many HAs were dissatisfied with the current arrangements, feeling that they had little control of GPs' health promotion activities. Two-thirds of HAs reported problems with monitoring GPs' health promotion activities.

Implementing quality: a study of the adoption and implementation of quality standards in the contracting process in a general practitioner multifund.

The increase in managerialism in the 1980s and the 1990 NHS reforms have had major implications for the regulation of providers. Purchasers of health care in the UK are now expected to specify three factors in their contracts: volume, cost and quality. This paper focuses on one of these: i.

Serum lipids and apolipoproteins in Spanish children and adolescents: a 5 year follow-up.

This study was designed to assess "tracking" of serum lipids and apolipoproteins in three age groups of Spanish children over a 5 year period. A total of 84 6-year-old, 89 10-year-old and 64 14-year-old children were evaluated in 1989 (with measurement of serum total cholesterol, triglycerides, lipoproteins and apolipoproteins A1 and B), and re-evaluated in 1994. Correlation coefficients between initial and final lipid and apolipoprotein values were as follows: total cholesterol, 0.

Research Design: Prospective clinical trial.

Setting: Pediatric hospital in Madrid, Spain.

Fibrinogen as a cardiovascular risk factor in Spanish children and adolescents. The Niño Jesus Group.

Studies done on adults reveal a significant role of fibrinogen (FG) in cardiovascular disease. The main purpose of our study was to determine the level of plasma FG in children, its distribution according to age and sex, and its relationship to other cardiovascular risk factors such as cigarette smoking, plasma lipid disturbances, and a positive family history for other cardiovascular risk factors. We studied a population of 2224 children, aged 2 to 18 years, from five different schools located in Madrid.

Smoking and apolipoproteins in adolescents. The Niño Jesus Group.

The relation between smoking and blood lipids and apolipoproteins (A1,B100) were studied in a group of 1024 12- to 18-year-old school children in the Comunidad de Madrid. The percentage of smokers was 19% (17% for girls and 21% for boys). The average consumption of cigarettes per day was 7.

[Asphyxia by immersion].

Nineteen childhood near drowning cases admitted to a private general hospital from December 31, 1983 through out December 1987 at a mean age of 2 years 3 months are discussed. All patients had diagnosis when first found by relatives, 16 were apneic and only 11 received some kind of resuscitation which complied with accepted standards in 4 of them. Seven cases were admitted in stage A of Conn, two in stage B and ten in stage C.

[Hemolytic-uremic syndrome. Experience with 154 cases].

One hundred and fifty four patients with hemolytic uremic syndrome (HUS) were admitted from year 1968 throughout 1989 to a public children's hospital (n = 139) and to a private general clinic (n = 15) at Metropolitan Santiago, Chile. Their mean age at admission was 16 months, 64% of them were 6 to 18 month old. One third of patients were admitted at spring season.

[Fulminant hepatic failure in children].

We report the clinical characteristics and course of 38 children with fulminant liver failure. A viral etiology was demonstrated in 19 patients out of 25 with serologic screening (virus A in 17 patients, B in 2 patients). One patient had toxic liver damage from ingestion of a caustic substance.

[The Fuenlabrada study: relationship between anthropometric variables and cardiovascular risk factors].

Anthropometric variables were studied in 2,153 healthy children, 1,115 males and 1,038 females, aged 0 to 18 years, of the Fuenlabrada population, Madrid. Height was measured by an anthropometer and weight by a weighting scale. Tricipital and subscapular skinfold thickness were measured by Holtain caliper.

[Fuenlabrada study: lipid and lipoprotein levels in children and adolescents associated with ischemic cardiopathy prevalence among their relatives].

The prevalence of coronary heart disease (CHD) was studied in parents and grandparents of 2,419 children surveyed for lipid levels. Children and their families were divided into 3 groups depending on the level of each lipid and lipoprotein studied in children: high greater than or equal to 95 percentile (p), medium 5-95 p, and low less than 5 p. Total cholesterol (Chol) and triglycerides (TG) were determined by enzymatic techniques in autoanalyzer.

[The Fuenlabrada study: arterial pressure in children and adolescents].

Blood pressure was studied in 2,153 healthy children of both sexes, from 0 to 18 years of age; 1,115 were males and 1,038 females. Systolic and diastolic blood pressures were measured in the sitting position by the auscultatory method on the right arm with a mercury sphygmomanometer using an appropriate cuff size. Systolic blood pressure was measured on the first sound and diastolic blood pressure in the fourth phase of Korotkoff.

[Mortality in pediatric intensive care units. The role of acute failure of organs and systems].

Previous health state and acute failure of six organ system (cardiovascular, respiratory, neurologic, hematologic, renal and digestive systems) at admission to a pediatric intensive care unit (ICU) were evaluated in 71 patients that died along one year in an ICU of a pediatric hospital at Santiago, Chile. Acute organic system failure (AOF) and chronic organic failure (COF) were defined on clinical, laboratory and therapeutic standards at hand in this country. COF was present in 56% of the cases, and was mainly due to congenital heart malformations.

[The Fuenlabrada study: a familial aggregation of ischemic cardiopathy and cardiovascular risk factors].

Unlabelled: Familial aggregation of coronary heart disease (CHD) and coronary risk factors (CRF) were evaluated by clinical history in adult relatives of children surveyed for CRF. Population was divided into two groups: Group I included 2,153 children without parental history of CHD. Group II included 266 children of 112 families with parental history of early CHD (before 56 years).

[Cardiorespiratory failure: results of resuscitation in a pediatric ICU].

Along one year, cardiorespiratory resuscitation was done to 71 patients, aged 3 days to 10 years (median 3.5 month), in a pediatric intensive care unit. Although 39 patients (55%) recovered through first-stage treatment, in 17 the arrest was recurrent and they died in the following 24 hours.

[The Fuenlabrada study: lipids and lipoproteins in children and adolescents].

Lipids and lipoproteins were studied in 2,153 healthy children, of both sexes, aged 0 to 18 years old, of Fuenlabrada, Madrid, population. We determined: Total Cholesterol (TC) and Triglycerides (TG) by automatized enzymatic techniques. C-HDL by precipitation method.

[Cardiovascular risk factors in children and adolescents in Fuenlabrada: objectives, features of the population, design, participation, equipment, laboratory technics, and quality control].

Fuenlabrada is at the present time the most industrialized town placed at the south are of Madrid. This population has some peculiar attractive characteristics from the epidemiologic point of view. Perhaps the most important is that the majority of its inhabitants are immigrant from other depressed rural areas of the country, with a low socio-economic and cultural level.

Biomass photochemistry: XI. Photochemical pretreatment of cellulose and its fungal degradation.

In order to study the single-cell proteins and cellulase production, fungal degradation of alpha-cellulose was tested. Photochemical pretreatment of alpha-cellulose at lambda > 254 nm increases by over 100% the cellulase production by Chrysonilia sitophila (TFB strain). This is reflected in a larger production of soluble proteins in the filtrate with higher cellulase activity when compared with unirradiated cellulose.
