Early alterations in serum creatine kinase and total cholesterol following high intensity eccentric muscle actions

Aim. The purpose of this experiment was to assess the levels of muscle soreness, serum total cholesterol (TC) and creatine kinase (CK) in the first 48 hours following fatiguing eccentric exercise performed with the triceps brachii.

The impact of newly identified loci on coronary heart disease, stroke and total mortality in the MORGAM prospective cohorts

Recently, genome wide association studies (GWAS) have identified a number of single nucleotide polymorphisms (SNPs) as being associated with coronary heart disease (CHD). We estimated the effect of these SNPs on incident CHD, stroke and total mortality in the prospective cohorts of the MORGAM Project. We studied cohorts from Finland, Sweden, France and Northern Ireland (total N=33,282, including 1,436 incident CHD events and 571 incident stroke events). The lead SNPs at seven loci identified thus far and additional SNPs (in total 42) were genotyped using a case-cohort design.We estimated the effect of the SNPs on disease history at baseline, disease events during follow-up and classic risk factors. Multiple testing was taken into account using false discovery rate (FDR) analysis. SNP rs1333049 on chromosome 9p21.3 was associated with both CHD and stroke (HR5=.20, 95% CI 1.08-1.34 for incident CHD events and 1.15, 0.99-1.34 for incident stroke). SNP rs11670734 (19q12) was associated with total mortality and stroke. SNP rs2146807 (10q11.21) showed some association with the fatality of acute coronary event. SNP rs2943634 (2q36.3) was associated with high density lipoprotein (HDL) cholesterol and SNPs rs599839, rs4970834 (1p13.3) and rs17228212 (15q22.23) were associated with non-HDL cholesterol. SNPs rs2943634 (2q36.3) and rs12525353 (6q25.1) were associated with blood pressure. These findings underline the need for replication studies in prospective settings and confirm the candidacy of several SNPs that may play a role in the etiology of cardiovascular disease.

A total synthesis of (+/-)-phomactin A

A total synthesis of the PAF antagonist phomactin A (1), isolated from the marine fungus Phoma sp. is described. The synthesis is based on a Cr(II)/Ni(II) macrocyclisation from the aldehyde vinyl iodide 14, leading to the key phomactatrienol intermediate 16a, followed by elaboration of 16a to the epoxyketone 21, which undergoes spontaneous pyran and hemiacetal ring formation to 1 on deprotection with DDQ.

Bogotá arte urbano o graffiti. Entre la ilegalidad y la forma artística de expresión

La investigación sobre el graffiti relacionado con el arte urbano, el diseño y la comunicación visual, la cultura social y política en la ciudad de Bogotá, son temas que concentran esta investigación. Opiniones y entrevistas fueron revelando la influencia sobre la comunidad, la sociedad civil, la política, y el enfrentamiento radical con la leyes, su clasificación y su exigencia según el estrato social han hecho de los espacios públicos de Bogotá una ciudad con paredes hablantes. Aunque no es tomado como algo malo, -para algunos- vandalismo para otros, despierta en muchos, opiniones diversas y sobre todo una subestimada valoración de los artistas hacia una expresión liberal y democrática de un sistema que los aleja de cualquier exhibición del arte tradicional.

Electronic cell counting to measure total cell numbers in bronchoalveolar lavage fluid

Cell counting of bronchoalveolar lavage (BAL) fluid is performed manually in routine practice. This has both methodological and inherent errors; however, the accuracy and suitability of automated counting devices have been questioned. In this study, a Coulter(R) Counter D Industrial model was calibrated and then used to measure the total cell count in unprocessed bronchoalveolar lavage fluid, and compared to a standard manual method.
