Cultivation of Agaricus blazei in the environmental protection area of the Baturité region under three types of casing soils

The outdoor cultivation (ditches) of Agaricus blazei was evaluated in the protected natural area (APA) of the mountainous region of Baturité on three types of casing soils (A, B and C). Casing soil A (horizon A) of the local soil was used (Alfisol). Casing B was obtained with a mixture of 30% of eucalyptus charcoal (1-2 cm of length) and 70% of horizon B of the local soil. Casing C was composed of 25% of vermiculite, 25% of coconut fiber and 50% of coarse sand. Temperature, relative humidity and pluviometric rates were monitored. The physical-chemical properties of the three casing soils were analyzed. The effect of the casing soil on the number and weight of the mushrooms, productivity, yield and biological efficiency of A. blazei were evaluated. The yield, productivity, biological efficiency and number of mushrooms were higher when using soil A. The highest productivity for soil A was attributed mainly to the physical characteristics, which were considered more appropriate for the cultivation, in addition to the high pluviometric rates and relative humidity. The productivity with soil A (9.62%) is comparable with the average productivity obtained in Brazil, meaning that the cultivation of A. blazei in this APA may have good perspectives for cultivation.

N-acetylglucosaminidase, myeloperoxidase and vascular endothelial growth factor serum levels in breast cancer patients

Inflammatory cells surround breast carcinomas and may act promoting tumor development or stimulating anti-tumor immunity. N-acetylglucosaminidase (NAG) has been employed to detect macrophage accumulation/activation. Myeloperoxidase (MPO) is considered a marker for neutrophils activity/accumulation. Vascular Endothelial Growth Factor (VEGF) is as strong pro-angiogenic cytokine. The aim of this study was to measure the systemic inflammatory response by measuring serum levels of NAG, MPO and VEGF in women diagnosed with breast cancer and associate this response to the peritumoral inflammatory infiltrate and to prognostic factors. Serum samples obtained from women with no evidence of disease (n = 31) and with breast cancer (n = 68) were analyzed for the activities of NAG, MPO and VEGF by enzymatic assay. Serum levels of NAG and VEGF were higher in healthy volunteers (P < 0.0001) and serum levels of MPO were higher in patients with breast cancer (P = 0.002). Serum levels of NAG were positively correlated to serum levels of MPO and VEGF (P < 0.0001 and P = 0.0012, respectively) and MPO and VEGF serum levels had also a positive correlation (P = 0.0018). The inflammatory infiltrate was not associated to serum levels of the inflammatory markers, and higher levels of MPO were associated to lymphovascular invasion negativity (P = 0.0175).

Prevalence of burnout syndrome in clinical nurses at a hospital of excellence

Background: Burnout syndrome can be defined as long-term work stress resulting from the interaction between constant emotional pressure associated with intense interpersonal involvement for long periods of time and personal characteristics. We investigated the prevalence/propensity of Burnout syndrome in clinical nurses, and the factors related to Burnout syndrome-associated such as socio-demographic characteristics, work load, social and family life, leisure activities, extra work activities, physical activities, and work-related health problems. Method: We conducted a cross-sectional, quantitative, prospective epidemiological study with 188 surgical clinic nurses. We used the Maslach Burnout Inventory (MBI), which is a socio-demographic questionnaire and the most widely used instrument to assess Burnout syndrome (three basic dimensions: emotional exhaustion, despersonalization and professional underachievement). The socio-demographic profile questionnaire wascomposed of questions regarding identification, training, time at work, work characteristics and personal circumstances. Results: The prevalence of Burnout syndrome was higher (10.1%) and 55, 4% of subjects had a propensity to develop this syndrome. The analysis of the socio-demographic profile of the nurse sample studied showed that most nurses were childless married women, over 35 years of age, working the day shift for 36 hours weekly on average, with 2-6 years of post-graduation experience, and without extra employments. Factors such as marital status, work load, emotion and work related stress aggravated the onset of the syndrome. Conclusion: The prevalence and propensity of Burnout syndrome were high. Some factors identified can be useful for the adoption of preventive actions in order to decrease the prevalence of the clinical nurses Burnout syndrome.

Ivabradine: Just another New Pharmacological Option for Heart Rate Control?

Ivabradine (IVB) is a heart rate lowering agent that acts via selective inhibition of the pacemaker funny current in sinoatrial nodal P cells, thus, reducing heart rate at rest and during exercise with minimal effect on myocardial contractility, blood pressure, and intracardiac conduction. IVB exerts no effect on external respiratory function parameters and it may also play a role in patients with concurrent chronic obstructive pulmonary disease. This property constitutes an important advantage over β-blockers. IVB acts by reducing the heart rate in a mechanism different from β-blockers, calcium channel blockers or late sodium channel blockers, three commonly prescribed antianginal drugs. As clinical trials have shown, it is remarkably well-tolerated and offers an alternative for patients who cannot take β-blockers. The combination of IVB and atenolol at commonly used doses in patients with chronic stable angina produced additional efficacy with no untoward effect on safety or tolerability. Additionally, side effects are rare and largely limited to a luminous phenomenon or phosphenes. This sensation is thought to be due to a block of Ih in the retina, a current very similar to cardiac If channels. IVB is contraindicated in patients with sick sinus syndrome or sinus node dysfunction and in patients taking hepatic inhibitors of Cytochrome P450 family 3, subfamily A, polypeptide 4 (abbreviated CYP3A4), with exception of omeprazole or lansoprazole. This review briefly summarizes the main studies regarding this drug.

Maturação de carne bovina

A maturação de carnes bovinas é uma importante ferramenta utilizada pelas empresas frigorificas visando um produto final com melhores características sensoriais, cada vez mais apreciadas pelos consumidores finais. O objetivo deste trabalho é elucidar os processos bioquímicos ocorrentes na musculatura que levam à sua transformação em carne e as tecnologias utilizadas visando o processo de maturação, que se consiste em manter a carcaça durante refrigeração por um tempo determinado. Durante a refrigeração, a temperatura, o pH e os níveis de ATP na musculatura determinam a ação das enzimas calpaínas e calpastatinas, que atuam sobre os filamentos de actina e miosina degradando a linha z, tornando assim a carne mais macia

Rehabilitacion oral sobre implantes instalados por medio de la tecnica sin colgajo (flapless) y carga inmediata

The oral rehabilitation with osseointegrated implants is a well-documented treatment with high rate of success. Nevertheless, demands related to treatment time and surgical technique began to appear. In this context, the procedure of immediate loading in which the dental prosthesis is placed right after implant surgery has become a constant practice. Although immediate loading has been an important advance, minimally invasive procedures, such as implant placement without raising a mucoperiosteal flap (flapless) are increasingly being performed. Association of immediate loading with the flapless technique improves acceptance by patients and professionals, because no suturing is required. Moreover, it reduces swelling, bleeding during and after surgery, postoperative pain, surgery time, discomfort and hematoma, as well as the need for postoperative medication. These characteristics ease the stages of rehabilitation soon after implant placement, cooperating with prosthodontist's work. Thus, the proposal of this study is to present a clinical case of oral rehabilitation with osseointegrated implants and fixed prosthesis in both arches, in which the flapless technique was applied, followed by immediate loading. It will discuss the diagnosis, prosthetic planning, surgical/prosthodontic procedures and follow-up for 20 months.
