Surface Soil Properties Influence Carbon Oxide Pulses After Precipitation Events in a Semiarid Vineyard Under Conventional Tillage and Cover Crops

引用

Pedosphere 2016年第4期26卷 499-509页

作者： fernando PEREGRINA CSIC-CAR-UR Instituto de Ciencias de la Vid y el Vino(ICVV)

In semiarid regions of the Mediterranean basin, a rainfall event can induce a respiratory pulse that releases a large amount of soil carbon dioxide （CO2） into the atmosphere; this pulse can significantly contribute to the annual ecosystem carbon （C） balance. The impacts of conventional tillage and two different cover crops, resident vegetation and Bromus catharticus L., on soil CO2 effiux were evaluated in a Vitis vinifera L. vineyard in La Rioja, Spain. Soil CO2 efflux, gravimetric water content, and temperature were monitored at a depth of 0-5 cm after rainfall precipitation events approximately every 10 d in the period from May 17 to July 27, 2012, during which the cover crops had withered. Additionally, on June 10, 2012, soil organic C, microbial biomass C, and I^-glucosidase activity were determined at soil depths of 0-2.5, 2.5-5, 5-15, and 15-25 cm. The results show that pulses of soil CO2 were related to the increase in soil water content following precipitation events. Compared to the conventional tillage treatment, both cover crop treatments had higher soil CO2 efflux after precipitation events. Both cover crop treatments had higher soil organic C, microbial biomass C, and β-glucosidase activity at the soil surface （0-2.5 cm） than the conventional tillage treatment. Each pulse of CO2 was related to the surface soil properties. Thus, this study suggests that the enhancement of soil organic C and microbiological properties at the soil surface under cover crops may increase soil CO2 efflux relative to conventional tillage immediately after precipitation events during the dry season.

Cell-free systems in the new age of synthetic biology

引用

Frontiers of Chemical Science and Engineering 2017年第1期11卷 58-65页

作者： fernando Villarreal Cheemeng Tan Department of Biomedical Engineering University of California Davis Davis One Shields Avenue CA 95616 USA

The advent of synthetic biology has ushered in new applications of cell-free transcription-translation systems. These cell-free systems are reconstituted using cellular proteins, and are amenable to modular control of their composition. Here, we discuss the historical advance- ment of cell-free systems, as well as their new applications in the rapid design of synthetic genetic circuits and components, directed evolution ofbiomolecules, diagnosis of infectious diseases, and synthesis of vaccines. Finally, we present our vision on the future direction of cell-free synthetic biology.

Introduction: Severe acute malnutrition remains one of the most important causes of under-five mortality. In Cameroon, the northern regions have the highest prevalence, with 1.4% in the Far North in 2021. These children are managed at the Internal therapeutic and Nutrional Centre, one of which is located at Maroua Regional Hospital, the third level referral Hospital. We therefore proposed to carry out a study on the clinical and evolutive aspects of these children. Materials and Methods: it was a descriptive, cross-sectional study from January 2020 to December 2022, at the ITNC (CNTI) of Maroua Regional Hospital. The sample size was obtained from the Lorentz formula. Patient records were used for data collection. We excluded all incomplete records and patients with less than 24 hours of admission. Results: Out of the 873 patients we recruited, the prevalence of severe malnutrition was estimated at 18 %. The average age was 14 months, with a male predominance. The main reasons for consultation were fever (42%) and diarrhoea (35%). Marasmus was the predominant clinical form. The major medical complications were sepsis (32.9%) and malaria (16.8%). HIV prevalence was 2.5% and tuberculosis was 4.9%. Most patients had haemoglobin levels between 7 and 10g/dl. 79.3% were cured and 6.5% died. The main causes of death were sepsis and malaria. Conclusion: Severe acute malnutrition remains a major problem in the Far North region. Several joint actions are needed to break this cycle.

Breast cancer is considered one of the most common cancers among women, accounting for 25% - 29% of new cases worldwide each year. The diagnosis, living with the disease, as well as the different treatments can have important impacts on the Psychological and mental health of patients. Objective: To investigate the psychological aspects that women with breast cancer develop or may develop. Methodology: A systematic review using the PRISMA methodology was used. Results: 11 articles that met the inclusion and exclusion criteria were analysed. The largest flow of publications in relation to the effects of the patient with cancer, were carried out between the years 2000 and 2023. Conclusions: Psychological disorders (depression, anxiety, stress) are part of the lives of women diagnosed with breast cancer, and their prevalence varies from one woman to another.

Morphology and distribution of Pronoctiluca (Dinoflagellata, incertae sedis) in the Pacific Ocean

引用

Acta Oceanologica Sinica 2013年第4期32卷 71-76页

作者： GóMEZ fernando Department of Biological Oceanography Institute of Oceanography University of S o Paulo

The diversity and distribution of Pronoctiluca, a marine dinoflagellate of enigmatic systematic position, was studied in the vicinity of the Kuroshio and Oyashio Currents, the Philippines, Celebes, Sulu and South China Seas, western and central equatorial and southeast Pacific Ocean. The abundance of Pronoctiluca was high- er, with a wide vertical distribution, in eutrophic temperate regions, whereas it was nearly absent in surface waters of oligotrophic tropical regions. Most of the specimens corresponded to P. spinifera. Pronoctiluca pelagica, covered by hyaline layers and with no flagella, is considered as an encysted form. The bipartition was only observed in P. acuta-P, spinifera forms, that together with the occurrence of intermediate forms between P. spinifera and P. pelagica suggest that they may correspond to developmental stages of a single species. Pronoctiluca is essential to understanding the evolutionary history of the alveolates.

Non-steroidal anti-inflammatory drugs:What is the actual risk of liver damage?

引用

World Journal of Gastroenterology 2010年第45期16卷 5651-5661页

作者： fernando Bessone Department of Gastroenterology and Hepatology University of Rosario School of Medicine2000RosarioArgentina

Non-steroidal anti-inflammatory drugs (NSAIDs) constitute a family of drugs, which taken as a group, represents one of the most frequently prescribed around the world. Thus, not surprisingly NSAIDs, along with antiinfectious agents, list on the top for causes of DrugInduced Liver Injury (DILI). The incidence of liver disease induced by NSAIDs reported in clinical studies is fairly uniform ranging from 0.29/100 000 [95% confidence interval (CI): 0.17-051] to 9/100 000 (95% CI: 6-15). However, compared with these results, a higher risk of liver-related hospitalizations was reported (3-23 per 100 000 patients). NSAIDs exhibit a broad spectrum of liver damage ranging from asymptomatic, transient, hyper-transaminasemia to fulminant hepatic failure. However, under-reporting of asymptomatic, mild cases, as well as of those with transient liver-tests alteration, in conjunction with reports non-compliant with pharmacovigilance criteria to ascertain DILI and flawed epidemiological studies, jeopardize the chance to ascertain the actual risk of NSAIDs hepatotoxicity. Several NSAIDs, namely bromfenac, ibufenac and benoxaprofen, have been withdrawn from the market due to hepatotoxicity; others like nimesulide were never marketed in some countries and withdrawn in others. Indeed, the contro-versy concerning the actual risk of severe liver disease persists within NSAIDs research. The present work intends (1) to provide a critical analysis of the dissimilar results currently available in the literature concerning the epidemiology of NSAIDS hepatotoxicity; and (2) to review the risk of hepatotoxicity for each one of the most commonly employed compounds of the NSAIDs family, based on past and recently published data.
