No full textLaser‐induced optothermal response of gold nanoparticles: From a physical viewpoint to cancer treatment application
No full textGold nanoparticles (GNPs)-based photothermal therapy (PTT) is a promising minimally invasive thermal therapy for the treatment of focal malignancies. Although GNPs-based PTT has been known for over two decades and GNPs possess unique properties as therapeutic agents, the delivery of a safe and effective therapy is still an open question. This review aims at providing relevant and recent information on the usage of GNPs in combination with the laser to treat cancers, pointing out the practical aspects that bear on the therapy outcome. Emphasis is given to the assessment of the GNPs' properties and the physical mechanisms underlying the laser-induced heat generation in GNPs-loaded tissues. The main techniques available for temperature measurement and the current theoretical simulation approaches predicting the therapeutic outcome are reviewed. Topical challenges in delivering safe thermal dosage are also presented with the aim to discuss the state-of-the-art and the future perspective in the field of GNPs-mediated PTT.

First report of collar and root rot caused by Phytophthora nicotianae on Lycium barbarum
No full textGoji (Lycium barbarum L.) is a Chinese-origin crop recently
introduced in Italy. In October 2016, collar and root rots associated
with severe twig dieback and foliage desiccation were
observed on more than 30% of two-year-old Goji plants in an
orchard in Bari province (Southern Italy). A Phytophthora sp.
was consistently isolated by plating small pieces of collar and
root decayed tissues on a BNPRAH selective medium (Erwin
and Ribeiro 1996). All isolates formed white arachnoid colonies
on potato-dextrose-agar, with papillate, persistent, pyriform
to spherical sporangia of 31–48 × 22–34 μm in size, and
globose chlamydospores of 20–32 μm in diameter, both terminal
and intercalary singly formed. Oospores were not observed.
Phenotypic characteristics matched those of
Phytophthora nicotianae (Erwin and Ribeiro 1996)
Phytophthora citrophthora is the predominant Phytophthora species in Syrian citrus groves
No full textA survey on Phytophthora spp. in the soils and roots of citrus groves was carried out in the main Syrian growing areas of Lattakia and Tartous. Traditional assays (selective medium with soil dilution plates) were used for pathogen detection, and molecular (PCR) assays were used for unanmbiguous identification of P. nicotianae and P. citrophthora in 38.5% of the collected samples. In both locations, P. citrophthora was the predominant species
Confocal laser scanning microscope study of terminal villi vessels in normal term and pre-eclamptic placentas
No full textThe aim of this study was to compare immunocytochemical confocal scanning laser microscopy measures of villus capillarization in control placentas with pre-eclamptic ones. Accordingly, placentas from normal term pregnancies (n=3) and cases of late-onset pre-eclampsia without intrauterine growth retardation (IUGR) featuring normal uterine artery Doppler (n=3) were analyzed by confocal scanning laser microscopy (CSLM), which is a powerful technique for obtaining three-dimensional reconstructions of any kind of blood vessels (arteries, veins, capillaries). A laser light beam is used in order to detect CD34 antibody-related immunofluorescence, which is a marker of endothelial cells. Villus capillarization was assessed by estimating the following parameters: number of pixels, mean, maximum and minimum immunofluorescence amplitude. Our results show a significant hyper-ramification of the capillary loop in pre-eclamptic placentas, featuring irregular profile and narrow lumina. Such findings support the hypothesis that several agents causing angiogenesis and vasoconstriction affect villus vessels in pre-eclamptic placentas, thus promoting a lasting condition of fetal hypoxia by decreasing endothelial surface and materno-fetal exchanges
