O plástico ficou ecológico

Matérias-primas renováveis como cana-de-açúcar e milho são usadas para produzir plásticos menos agressivos ao meio ambiente

No tempo que você levará para ler esta reportagem, cerca de 50 000 sacolinhas plásticas serão consumidas no Brasil. A média nacional é de 1,5 milhão por hora. Embora representem pouco individualmente, os saquinhos de supermercado formam um volume enorme de lixo, que pode demorar vários séculos para se decompor no ambiente. Como reduzir o impacto causado pelo plástico na natureza é uma preocupação crescente. Por isso, ganham cada vez mais espaço as iniciativas de produzir plástico a partir de matérias-primas renováveis, como a cana- de-açúcar e o milho.

An interethnic comparison of the distribution of vitamin D receptor genotypes and haplotypes

 Clin Chim Acta 2007; 384(1-2):155-9

BACKGROUND: The biological actions of vitamin D receptor (VDR) may be affected by genetic variations in the VDR gene. While there are interethnic differences in the frequency of VDR gene variants, there is little haplotype information, especially from admixed populations. We examined the distribution of genetic variants of 3 VDR polymorphisms (BsmI, ApaI and FokI) and haplotypes in black and white Brazilians. We have also compared our results with those from the HapMap project. METHODS: We studied 120 subjects

Influence of eNOS haplotypes on the plasma nitric oxide products concentrations in hypertensive and type 2 diabetes mellitus patients.

Endothelial nitric oxide synthase (eNOS) haplotypes are associated with hypertension (HT) in patients with or without type 2 diabetes mellitus (T2DM). We evaluated the association of eNOS genotypes/haplotypes with the plasma concentrations of nitrite/nitrate (NO(x)), which are products of nitric oxide in HT, T2DM, and T2DM+HT patients. We studied eNOS polymorphisms in the promoter region (T-786C), in exon 7

Endothelial nitric oxide synthase haplotypes are related to blood pressure elevation, but not to resistance to antihypertensive drug therapy

OBJECTIVES: Most hypertensive patients require two or more drugs to control arterial blood pressure effectively. Although endothelial nitric oxide synthase (eNOS) haplotypes have been associated with hypertension, it is unknown whether eNOS genotypes/haplotypes are associated with resistance to antihypertensive therapy. METHODS: We studied the distribution of three eNOS genetic polymorphisms: single nucleotide polymorphisms in the promoter region (T(-786)C), and in exon 7 (Glu298Asp), and a
