Article Synopsis
- Ecosystem management and restoration can boost carbon storage, but knowledge gaps about soil organic carbon (SOC) in specific ecosystems challenge effective climate policies.
- The paper analyzes SOC stock variability in Brazil's main grassy ecosystems and compiles a comprehensive dataset from 182 studies, including soil properties and carbon stocks across various locations.
- Findings reveal that subtropical grasslands have the highest SOC stocks, while other ecosystems like the Cerrado and Amazon are notable for their subsurface carbon levels, with implications for Brazil's greenhouse gas inventory.
Article Synopsis
- X-linked Charcot-Marie-Tooth disease type 6 (CMTX6) is a rare genetic disorder caused by mutations in the PDK3 gene, with only three previously reported families from Australia, South Korea, and Germany; this study focuses on two Brazilian families affected by the condition.
- The researchers utilized clinical assessments, electrophysiological evaluations, and whole-exome sequencing to investigate the disease's genetic basis and observed varying symptoms between affected males and females within the families.
- The study identifies a new variant in the PDK3 gene and finds similarities in the clinical presentations across the different families, emphasizing the importance of global collaboration in understanding rare genetic disorders like CMTX6.
This study aimed to evaluate the biomass production of Spirulina sp. LEB 18 cultivated in wastewater from the desalination process. The outdoor cultivations (210 L) were performed using as culture medium 100% wastewater supplemented with 25% of Zarrouk constituents (Tcs).

Although grazing exclusion has been studied elsewhere, the consequences of alleviating the disturbance regime in grassland ecosystems remain unclear. In this paper, we present results of the first five years of an experiment in native grasslands of southern Brazil.

Method: A descriptive, qualitative, exploratory study based on the Reason safety model performed at the Intensive Care Unit of a specialized hospital, with nurses working in the direct management of continuous hemodialysis, who were interviewed using a script with its contents being thematically analyzed.
Results: 23 nurses participated.
Objective: In this article, we offer an extended critical review of a new conception of bioethics, presented by Darlei Dall'Agnol, in the book Care and Respect in Bioethics.
Methods: Critical philosophical analysis of background assumptions of a new approach to bioethics, enriched with critical discussion of related philosophical literature.
Results: In Care and Respect in Bioethics, through an approach filled with hard cases, Dall'Agnol argues that the metaethics of respectful care has theoretical advantages over the intuitionist metaethics of principlism and the particularism of casuistry, offering an original comprehensive approach that crosses the three dimensions of ethical inquiry: metaethical, normative, and applied ethics.
The objective was to evaluate the effect of reusing Zarrouk's medium on a Spirulina sp. LEB 18 culture by determining kinetic parameters, chemical composition, biofuels, and thermal characterization. Cultivation was performed in a raceway bioreactor for 7 days, the supernatant was reused for four cycles.

Method: Qualitative research developed considering James Reason's reference in the Intensive Care Unit of a private hospital. The data was collected with 23 nurses who worked for more than three months in the management of continuous hemodialysis through a semi-structured interview, and analyzed with the thematic content analysis technique.
Objectives: To identify equipment failures during handling by nurses and analyze the conduct of the professionals when these failures occur.
Methods: Descriptive, exploratory and qualitative study, whose field was the intensive care unit of a public institution, and the participants were day nurses that worked providing direct care to patients. Data were produced in 2014 through systematic observation and interviews and were examined with thick description and content analysis.
Article Synopsis
- This study investigated how nitrogen availability affects the growth, biomass composition, and polyhydroxyalkanoate (PHA) production in three microalgae species: Chlorella minutissima, Synechococcus subsalsus, and Spirulina sp. LEB-18.
- Limited nitrogen availability led to decreased cellular growth and changes in biochemical composition, such as protein degradation and increased lipid accumulation, with Chlorella minutissima failing to produce PHAs under nitrogen-deficient conditions.
- The highest PHA production occurred after 15 days, with Synechococcus subsalsus achieving 16% and Spirulina sp. LEB-18 reaching 12% of
Article Synopsis
- The study analyzed the fatty acid profiles of different Xanthomonas pathovars that produce xanthan gum to identify chemical markers related to its productivity and quality.
- Three strains were examined after 168 hours of fermentation, with their samples extracted and characterized for xanthan.
- A significant finding was that the Xanthomonas axonopodis pv manihotis 290 strain had a higher unsaturated/saturated fatty acid ratio, which correlated with greater xanthan production, although no link was found between fatty acid composition and the xanthan's characteristics.
Gastric cancer is one of the most frequent malignant tumors in the world. The majority of patients are diagnosed with metastatic gastric cancer, which has a low survival rate. These data reinforce the importance of studying the anticancer activity of new molecules with the potential to suppress gastric cancer metastasis.
