L. essential oil: chemical characterisation and antimicrobial activity against methicillin-resistant .

L. essential oil has attracted the interest of the scientific community thanks to its numerous biological activities. Several studies have evaluated EOs as alternative therapeutic approaches to limit the use of antibiotics; the present study aimed to evaluate the inhibitory and bactericidal activity of the essential oils obtained from the leaves and inflorescences of two hemp genotypes against twenty-one multidrug-resistant, methicillin-resistant strains isolated from canine clinical samples.

Mesophotic zone as buffer for biodiversity protection: A promising opportunity to enhance MPA effectiveness.

Coastal areas conservation strategies often left deeper habitats, such as mesophotic ones, unprotected and exposed to anthropogenic activities. In this context, an approach for including the mesophotic zone inside protection plans is proposed, considering 27 Italian Marine Protected Areas (MPAs) as a model. MPAs were classified considering their bathymetries, exposure to marine heat waves (MHWs), mass mortality events (MMEs) and, using a local ecological knowledge (LEK) approach, the estimated resilience of certain sessile species after MMEs.

Energy content of anchovy and sardine using surrogate calorimetry methods.

European anchovy (Engraulis encrasicolus) and sardine (Sardina pilchardus) are crucial species for the marine ecosystem of the Northwestern Mediterranean Sea. They account for a high percentage of fish landings and they represent an important economic income for the fishery sector. Concerns over their stock status are rising in recent years as biomass, growth, reproductive capacity, and body condition of both species are declining, with latitudinal variations.

Immunomodulatory effects of IFN-beta1a treatment alone or associated with pentoxifylline in patients with relapsing-remitting multiple sclerosis (RRMS).

Interferon-beta1a (IFN-beta1a) and pentoxifylline (PTX) are reported to be active in relapsing-remitting multiple sclerosis (RRMS), but the mechanisms are not completely understood. In two groups of RRMS patients, we studied the phenotype of peripheral lymphocytes and the level of several cytokines both in sera and in supernatants of activated peripheral blood mononuclear cells (PBMC) before and after 8 months of therapy with IFN-beta1a alone or associated with PTX. Our data indicate that patients with RRMS, treated with IFN-beta1a, exhibited a significant increase in CD4(+)CD25(++) T suppressor cells, accompanied by a significant decrease in cytotoxic lymphocytes (CD8(+)CD28(-) and natural killer [NK] cells) and IFN-gamma production, which could both contribute to an explanation of the previously described beneficial effects of IFN-beta treatment in MS.

Atrial tachycardia with recipient-to-donor atrioatrial conduction and isthmus-dependent donor atrial flutter in a patient after orthotopic heart transplantation. Successful treatment by radiofrequency catheter ablation.

Atrial arrhythmias are common after orthotopic heart transplantation. We report an unusual case of a patient after heart transplantation with 2 types of atrial arrhythmias: one was a macro-reentrant, incisional, recipient-atrial tachycardia conducted to the donor atrium, and the other was a common-type, isthmus-dependent atrial flutter in the donor atrium. These 2 arrhythmias were successfully treated with selective radiofrequency catheter ablation.
