Fungal secondary metabolites play a highly significant role in crop protection, which is related to their antifungal activity against agriculturally important phytopathogens. In fact, plant diseases caused by fungi including species belonging to the genera of , , and have become increasingly serious affecting crop yield and quality. Hence, there is increasing awareness by the scientific community of the importance of exploiting fungal products for finding new compounds able to inhibit phytopathogens.

In this respect, as part of our ongoing work aiming at using fungal pathogens as an alternative to common herbicides, the foliar pathogen has been evaluated to control buffelgrass (). In particular, in this work, the isolation and structural elucidation of two new biosynthetically related metabolites, named nigrosphaeritriol (3-(hydroxymethyl)-2-methylpentane-1,4-diol) and nigrosphaerilactol (3-(1-hydroxyethyl)-4-methyltetrahydrofuran-2-ol), from the phytotoxic culture filtrate extract were described, along with the identification of several known metabolites.

Each class of antiretrovirals has, however, different characteristics and different tolerability profiles. The literature data show that protease inhibitors (PIs) are associated with a higher incidence of dyslipidemia.

It is classified as a possible human carcinogen by international authorities based on sufficient evidence of carcinogenicity from studies in experimental animals. Although a vast number of studies both in vitro and in vivo have been performed to investigate furan genotoxicity, the results are inconsistent, and its carcinogenic mode of action remains to be clarified.

"Patient-centred care" is the recent response to the malaise produced in the field of health care from the point of view both of a technical mentality and the paternalistic model. The interest in the story-telling approach shown by both the humanities and the social sciences has favoured a "narrative turn" in medicine too, where the new ethics of therapeutic relationship consider the hermeneutic method a means by which to integrate evidence and subjectivity, scientific data and patient experience. The aim of this paper is to show how Ricoeur's theory of "threefold mimesis" makes a conceptual contribution to the use of narrative interviews in nursing and also be successfully transferred into and applied in the field of healthcare in general.

The dog was treated with a Robert Jones-like bandage as a conservative approach, and was subjected to X-ray, B-mode, Color Doppler and contrast-enhanced ultrasound (CEUS) examinations during the fracture healing, in order to assess bone hemodynamic changes. B-mode, Power Doppler and CEUS examinations of the fracture gap were performed at 7, 20, 35, and 50 days post-trauma.

Newborns, especially if born preterm, are more vulnerable to medication errors than adults. Recently, robotic medication compounding has reportedly improved the safety and efficiency of the therapeutic process.

In this study, with a hermeneutic phenomenological design and an interpretation method inspired by the philosophy of Ricoeur, we conducted in-depth interviews with 14 elderly people at a social day center in Rome (Italy). The analysis revealed three central themes associated with the experience of being old: changes and limitations related with being aged, the experience that comes from having lived a long life, and an awareness of death.

Contaminants belonging to various classes, including polychlorobiphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs), organochlorine pesticides (OCPs), organophosphorus pesticides (OPPs), pyrethroid insecticides (PYRs), fungicides (Fs), herbicides (Hs), synergists (SYNs) and insect growth regulators (IGRs) were analysed simultaneously in honey samples using a new simultaneous, easy and rapid method based on a liquid-liquid extraction with a mixture of n-hexane and ethyl acetate. It allowed recoveries in the range 80-137%, with limits of detection (LODs) between 0.10 and 5.
View Article and Find Full Text PDFMore and more seems to be necessary to find new ways of communication between medical doctors and bioethicists in order to build a shared vocabulary and to prevent conflicts: many bioethical problems seem to be caused by the lack of dialogue between them, which both seem to speak two different languages. Improving this dialogue means searching new languages and innovative forms of communication: the narration could be a really effective tool to enhance the physicians' and bioethicist's moral conscience, since it facilitates reasoning on someone's particular experience, and, ultimately, on our experience. Starting from the results of a questionnaire administered to a group of students of the Faculty of Medicine and Surgery of the University Campus Bio-Medico we present a theoretical discussion about the need for more dialogue and for a shared vocabulary in medical experiences.

The scheme of symptom diagnosis treatment healing is to be replaced in these cases with a treatment based on an open system of uncertain length and results. It is a model called ″medicine of incurable″, which aims to combat the discomfort of the disease rather than the fight against the disease.

With the aim to thoroughly elucidate the polyphenolic profile of this variety, listed as Protected Geographical Indication product, an extensive qualitative profiling of Annurca apple polyphenolic peel extract was carried out, by employing a combination of ultra high performance reversed phase (RP-UHPLC) and hydrophilic liquid chromatography (HILIC) coupled to ion trap-time of flight (IT-TOF) mass spectrometry. A total of 63 compounds were tentatively identified, 25 of which not reported in Annurca apple extract so far.

We measured free radical production in acellular conditions by Electron Paramagnetic Resonance technique and genotoxicity by micronucleus and Comet assays. Oxidative DNA damage was assessed by modified Comet assay and by measuring 8-oxodG steady state levels.

This post-nature which aspires to be perfect, immortal, invulnerable, is entirely devoid of beauty. In fact, while there may be an aesthetic of the artificial and of the artefact if it is in relation to objects, there is, however, no aesthetic of the post-human body.

The expression of hMTH1, the human hydrolase that degrades oxidized purine nucleoside triphosphates, grants protection in a chemical HD mouse model in which HD-like features are induced by the mitochondrial toxin 3-nitropropionic acid (3-NP). To further examine the relationship between oxidized dNTPs and HD-like neurodegeneration, we studied the effects of hMTH1 expression in a genetic cellular model for HD, such as striatal cells expressing mutant htt (Hdh(Q111)).
