Carros de emergência: disponibilidade dos itens essenciais em um hospital de urgência norteriograndense

It is a descriptive, exploratory and quantitative study that evaluates, by the standards of the Brazilian Society of Cardiology (SBC), the availability of the items of the Level I Emergency Cars (EC) of the largest emergency hospital in Rio Grande do Norte. Data were collected during the month of November 2010, the sample consists of 12 EC. All EC analyzed showed gaps in availability of essential items, being the greatest deficiencies related to materials intended for vascular access, circulation control and drugs aimed at treating the causes of cardiac arrest. It was felt institution, as well as a protocol, difficult routine check of the EC, the nurse assigned task.Se trata de una investigación descriptiva, exploratoria y cuantitativa con el objetivo de evaluar, bajo los patrones de la Sociedad Brasileña de Cardiología (SBC), la disponibilidad de los artículos de nivel I de los Carros de Emergencia (CE) del mayor hospital de urgencia de Rio Grande do Norte.

New volatile constituents from leaves of Stemodia trifoliata (Link.) Reichb. (Schrophulariaceae)

The leaf essential oils of Stemodia trifoliata (Scrophulariaceae), collected at the same month of two different years (August 2005 and 2006), were analized by GC-MS and GC-FID. A total of 22 volatile components represented by sesquiterpenes and diterpenes was identified. β-Caryophyllene (9.4-15.4%) and caryophyllene oxide (6.2-9.0%) were the major compounds identified in the sesquiterpene fraction, while the diterpenoids 6α-acetoxymanoyl oxide (13.9-23.2%) and 6α-hydroxymanoyl oxide (25.1-29.7%) were the main constituents of the diterpene fraction. The two novel manoyl oxide derivatives had their structures established by means of spectroscopic methods, particularly 1D and 2D NMR. This work describes for the first time the chemical investigation on the volatile composition of S. trifoliata

Bacterial cellulose production by Gluconacetobacter xylinus by employing alternative culture media

Bacterial cellulose (BC) is used in different fields as a biological material due to its unique properties. Despite there being many BC applications, there still remain many problems associated with bioprocess technology, such as increasing productivity and decreasing production cost. New technologies that use waste from the food industry as raw materials for culture media promote economic advantages because they reduce environmental pollution and stimulate new research for science sustainability. For this reason, BC production requires optimized conditions to increase its application. The main objective of this study was to evaluate BC production by Gluconacetobacter xylinus using industry waste, namely, rotten fruits and milk whey, as culture media. Furthermore, the structure of BC produced at different conditions was also determined. The culture media employed in this study were composed of rotten fruit collected from the disposal of free markets, milk whey from a local industrial disposal, and their combination, and Hestrin and Schramm media was used as standard culture media. Although all culture media studied produced BC, the highest BC yield60 mg/mLwas achieved with the rotten fruit culture. Thus, the results showed that rotten fruit can be used for BC production. This culture media can be considered as a profitable alternative to generate high-value products. In addition, it combines environmental concern with sustainable processes that can promote also the reduction of production cost.The authors would like to acknowledge the Brazil National Council of Technological and Scientific Development (CNPq, FAPESP, and CAPES), the financial support from FAPESP 2009/14897-7, and Fundacao para a Ciencia e a Tecnologia (FCT)/Portugal through the project PTDC/EBB-EBI/112170/2009 for the financial support and scholarship.

MTHFR and MTR Polymorphisms and Breast Cancer in Brazilian Women

Breast cancer (BC) is the second most common cancer, and mortality rates remain high among Brazilian women. However, the role of single nucleotide polymorphisms (SNPs) in one-carbon metabolism genes in breast cancer in Brazilian women is less clear. We aimed examine the association between the SNPs, in two genes in one-carbon metabolism alone and in cumulation, and the risk of breast cancer in an Brazilian population based case-control study of 257 breast cancer cases and 177 controls. Our hypothesis was woman who carries more risk genotypes has a higher susceptibility for developing breast cancer. Genotyping for MTHFR C677T and MTR A2756G polymorphisms were performed using polymerase chain reaction-restriction fragment length polymorphism analysis (PCR-RFLP) method. Our results in population studied indicated that 677 CgtT and 2756 AgtG substitution does not appear to influence the risk of breast cancer. The cumulative effect was not observed with the OR being gradually elevated with increasing number of risk genotypes. However, larger studies are needed to further examine this interactions in this pathway and breast cancer risk in Brazilian women, as well in women of others nationalities

Composição química e atividade biológica das folhas e frutos de Triphasia trifolia

The chemical composition of the essential oils from leaves and fruits of Triphasia trifolia was analyzed by GC-FID and GC-MS. The major constituents of oil obtained from leaves were sabinene (35.4%) and myrcene (34.1%), while the prevalent compounds in oil from fruits were sabinene (37.2%), beta-pinene (23.95) and gamma-terpinene (16.3%). Both oils showed moderate antimicrobial activity. The fruit decoction was also investigated leading to the isolation of the coumarins isopimpinelin, (R)-byakangelicin and (S)-mexoticin. From leaves were isolated the coumarins (R)-byakangelicin, aurapten, (S)-mexoticin, isosibiricin, isomerazin and coumurrayin and the flavonoid vitexin. All coumarins showed cholinesterase inhibition on TLC tests
