Metabolomics Suggests That Soil Inoculation with Arbuscular Mycorrhizal Fungi Decreased Free Amino Acid Content in Roots of Durum Wheat Grown under N…
2015
Arbuscular mycorrhizal fungi (AMF) have a major impact on plant nutrition, defence against pathogens, a plant's reaction to stressful environments, soil fertility, and a plant's relationship with other microorganisms. Such effects imply a broad reprogramming of the plant's metabolic activity. However, little information is available regarding the role of AMF and their relation to other soil plant growth-promoting microorganisms in the plant metabolome, especially under realistic field conditions. In the present experiment, we evaluated the effects of inoculation with AMF, either alone or in combination with plant growth-promoting rhizobacteria (PGPR), on the metabolome and changes in metabo…
Inherited semisterility for control of harmful insects. I. Productions of semisterility due to translocation in the mosquito,Culex pipiens L., by X-r…
1971
In Anbetracht der theoretischen und in einem Freilandexperiment bereits erwiesenen Moglichkeit der Bekampfung von Schadinsekten durch Freilassung semisteriler Tiere wurde die Produktion von Translokationen und damit verbundener Semisterilitat bei der StechmuckeCulex pipiens untersucht. Die Totalrate der erzeugten Translokationen liegt bei Stechmucken im Vergleich zuDrosophila auffallend hoch. Es besteht offenbar eine Korrelation zwischen der Gesamtlange der Chromosomen und der Translokationsrate.
Wastewaters from citrus processing industry as natural biostimulants for soil microbial community
2020
Abstract Citrus fruit processing wastewaters (CWWs), being rich in organic matter, may be a valuable resource for agricultural irrigation and, possibly, for the improvement of soil organic carbon (TOC). This issue is becoming crucial for soils of arid and semiarid environments increasingly experiencing water scarcity and continuous decline of TOC towards levels insufficient to sustain crop production. However, before using CWWs in agriculture their effects on the soil living component have to be clarified. Therefore, in this study we assessed the impact of CWWs on soil chemical and biochemical properties. Under laboratory conditions, lemon, orange and tangerine wastewaters were separately a…
Sarcoma Botryoides: Optimal Therapeutic Management and Prognosis of an Unfavorable Malignant Neoplasm of Female Children
2023
Embryonal rhabdomyosarcoma (ERMS) is a rare malignancy and occurs primarily in the first two decades of life. Botryoid rhabdomyosarcoma is an aggressive subtype of ERMS that often manifests in the genital tract of female infants and children. Due to its rarity, the optimal treatment approach has been a matter of debate. We conducted a search in the PubMed database and supplemented it with a manual search to retrieve additional papers eligible for inclusion. We retrieved 13 case reports and case series, from which we summarized that the current trend is to approach each patient with a personalized treatment plan. This consists of a combination of local debulking surgery and adjuvant or neoad…
Conflict between parasites with different transmission strategies infecting an amphipod host
2005
Competition between parasites within a host can influence the evolution of parasite virulence and host resistance, but few studies examine the effects of unrelated parasites with conflicting transmission strategies infecting the same host. Vertically transmitted (VT) parasites, transmitted from mother to offspring, are in conflict with virulent, horizontally transmitted (HT) parasites, because healthy hosts are necessary to maximize VT parasite fitness. Resolution of the conflict between these parasites should lead to the evolution of one of two strategies: avoidance, or sabotage of HT parasite virulence by the VT parasite. We investigated two co-infecting parasites in the amphipod host, G…
International consensus and practical guidelines on the gynecologic and obstetric management of female patients with hereditary angioedema caused by …
2012
Background There are a limited number of publications on the management of gynecologic/obstetric events in female patients with hereditary angioedema caused by C1 inhibitor deficiency (HAE-C1-INH). Objective We sought to elaborate guidelines for optimizing the management of gynecologic/obstetric events in female patients with HAE-C1-INH. Methods A roundtable discussion took place at the 6th C1 Inhibitor Deficiency Workshop (May 2009, Budapest, Hungary). A review of related literature in English was performed. Results Contraception : Estrogens should be avoided. Barrier methods, intrauterine devices, and progestins can be used. Pregnancy : Attenuated androgens are contraindicated and should …
Correlates of the non-use of contraception among female university students in Italy
2021
The present paper scrutinizes the correlates of the non-use of contraception among young women in Italy. To this end we consulted two releases of Selfy (Sexual and Emotional LiFe of Youths) survey, which offer information for a nationally sample of university students. The results reveal that the likelihood of non-using contraception is higher among women living in the South and among those with previous experience of unsafe sexual behaviours. The risk of unprotected sex is also higher within a group of students who are relatively older than the others and live in a stable cohabiting union.
Unprotected sex among female Italian uni- versity students: A «Calculated Risk»
2022
Contraception is considered a rational strategy to prevent unwanted births. However, beyond the dichotomy of «planned» and «unplanned» pregnancy, behaviours are sometimes ambivalent or contradictory. The present paper inves tigates the reasons beyond the non-use of contraception in Italy by examining a large-scale survey of university students conducted in 2000 and 2017. The findings reveal a small but clearly defined group of young female students, cohabiting with their partner and residing in the South of the country, who have a high frequency of sexual intercourses and do not deliberately use any contra ceptive method. These findings offer population-based evidence about the ex istence o…
Nitrogen fertilisation in coriander (Coriandrum sativumL.): a review and meta-analysis
2009
Nitrogen (N) fertilisation is one of the most important external inputs in assessing coriander seed yield and plant growth. Recent concerns related to the misuse of N fertilisers in agricultural environments, however, stress the opportunity for a fine-tuning of N management in order to optimise the use of this element, avoiding losses and reducing environmental hazards. In this study, some results from the literature concerning N fertilisation in coriander are reviewed and, by means of statistical analysis, an attempt is made to derive from them some general suggestions about practices of N fertilisation. In most cases examined, N fertilisation allowed a 10–70% increase in seed yields in co…
Fertility and breast cancer: A literature review of counseling, preservation options and outcomes.
2021
Fertility preservation is an important issue in breast cancer patients undergoing oncological treatment. Fertility counseling is a crucial need given the physical and psychological stress experienced by patients. Cryopreservation of mature oocytes is currently the standard fertility-preserving procedure. Other options such as ovarian tissue preservation or gonadal protection during chemotherapy are still experimental, but have proven effectiveness. Prompt referral to a fertility unit is highly recommended in order to ensure quality of care. In this article, we focus on the different strategies to preserve fertility in breast cancer patients, assessing also the safety of pregnancy and breast…
