Abstract: moyamoya disease is a unique chronic progressive cerebrovascular disease characterized by bilateral stenosis or occlusion of the arteries around the circle of willis with prominent arterial collateral circulation. it can be primary or secondary to genetic syndromes such as down syndrome. we report a seven year-old girl with a down syndrome that presented with a disturbance of consciousness, seizures and a right hemiparesia at the age of five. magnetic resonance imaging showed old cortical ischemic lesions in both cerebral hemispheres and a recent infarction in the territory of the ?eft middle cerebral artery. brain angiography showed a proximal stenosis of both medial cerebral arteries and a net of collateral vessels, consistent with the diagnosis of moyamoya syndrome. the patient had also an antithrombin iii deficiency. aspirin was indicated and a surgical correction was recommended. however, prior to the procedure, the patient had a new infarction in the territory of the right middle cerebral artery, which caused a severe disability.
Endocannabinoid System and Psychiatry: In Search of a Neurobiological Basis for Detrimental and Potential Therapeutic Effects

Abstract: Public concern on mental health has noticeably increased given the high prevalence of neuropsychiatric disorders. Cognition and emotionality are the most affected functions in neuropsychiatric disorders, i.e., anxiety disorders, depression, and schizophrenia. In this review, most relevant literature on the role of the endocannabinoid (eCB) system in neuropsychiatric disorders will be presented. Evidence from clinical and animal studies is provided for the participation of CB1 and CB2 receptors (CB1R and CB2R) in the above mentioned neuropsychiatric disorders. CBRs are crucial in some of the emotional and cognitive impairments reported, although more research is required to understand the specific role of the eCB system in neuropsychiatric disorders. Cannabidiol (CBD), the main non-psychotropic component of the Cannabis sativa plant, has shown therapeutic potential in several neuropsychiatric disorders. Although further studies are needed, recent studies indicate that CBD therapeutic effects may partially depend on facilitation of eCB-mediated neurotransmission. Last but not least, this review includes recent findings on the role of the eCB system in eating disorders. A deregulation of the eCB system has been proposed to be in the bases of several neuropsychiatric disorders, including eating disorders. Cannabis consumption has been related to the appearance of psychotic symptoms and schizophrenia. In contrast, the pharmacological manipulation of this eCB system has been proposed as a potential strategy for the treatment of anxiety disorders, depression, and anorexia nervosa. In conclusion, the eCB system plays a critical role in psychiatry; however, detrimental consequences of manipulating this endogenous system cannot be underestimated over the potential and promising perspectives of its therapeutic manipulation.

Abstract: cultivation of the shrub rosmarinum officinalis l. is of great interest due to its aromatic and medicinal properties. in 2004, in the south of buenos aires province (argentina), rosemary plants showing wilt and necrotic lesions in leaves, stems and twigs (die back) were observed in the field and the greenhouse. this work has focused on the identification of the causal agent of the above mentioned pathology. forty plants were examined and segments of the symptomatic tissues from ten of them were disinfected with a 2% sodium hypochlorite solution, rinsed in sterile water and plated into petri dishes with potato dextrose agar (pda, 2%). the plates were incubated at 22oc for eight days. grayish white colonies and acervuli with conidia in orange masses and dark setae were observed on the all tissue segments. the cylindrical shaped conidia germinated developing mycelium or apressoria. the isolate was identified as colletotrichum gloesporioides (penz) penz & sacc. to confirm its pathogenicity, leaves and twigs taken from ten healthy plants were inoculated with a suspension of the fungus using a hypodermic syringe, the control was inoculated with sterile distilled water. this material was cultured in petri dishes with pga. this test reproduced the symptoms observed in the field and greenhouse. between 24_48 h after inoculation, all the tissues developed necrosis. the pathogen was then reisolated from leaves and twigs fulfilling koch′s postulates. the controls remained symptomless. this is the first report of colletotrichum gloesporioides as the causal agent of die back in rosmarinum officinalis in argentina.

Materials , 2009, DOI: 10.3390/ma2031288
Abstract: This review compiles the work performed in the field of organic solid-state lasers with the hole-transporting organic molecule N,N′-bis(3-methylphenyl)-N,N′-diphenylbenzidine system (TPD), in view of improving active laser material properties. The optimization of the amplified spontaneous emission characteristics, i.e., threshold, linewidth, emission wavelength and photostability, of polystyrene films doped with TPD in waveguide configuration has been achieved by investigating the influence of several materials parameters such as film thickness and TPD concentration. In addition, the influence in the emission properties of the inclusion of a second-order distributed feedback grating in the substrate is discussed.

International Journal of Molecular Sciences , 2010, DOI: 10.3390/ijms11062546
Abstract: This paper aims to review the recent advances achieved in the field of organic solid-state lasers with respect to the usage of semiconducting organic molecules and oligomers in the form of thin films as active laser media. We mainly focus on the work performed in the last few years by our research group. The amplified spontaneous emission (ASE) properties, by optical pump, of various types of molecules doped into polystyrene films in waveguide configuration, are described. The various systems investigated include N, N′-bis(3-methylphenyl)- N, N′-diphenylbenzidine (TPD), several perilenediimide derivatives (PDIs), as well as two oligo-phenylenevinylene derivatives. The ASE characteristics, i.e., threshold, emission wavelength, linewidth, and photostability are compared with that of other molecular materials investigated in the literature.

Abstract: A series of N-acetylated cationic gemini surfactants (3a-e) having dimeric structures derived from tertiary amines were synthesized. Their antifungal potency and surface properties were determined. It also studied the acute toxicity of the molecule with the best performance and the best water solubility (3e) through Chlorella vulgaris and Daphnia magna bioassays. The results were compared to those obtained for a commercially available reference compound 2-(thiocyanomethylthio) benzothiazole (TCMTB). Parameters such as surface tension (ϒCMC), critical micelle concentration (CMC), surface excess concentration (Γ), and area per molecule (A) were determined. The resulting values indicated that the five gemini surfactants are characterized by good surface-active and self-aggregation properties. All surfactants were tested to evaluate their antifungal activity. Six fungal strains were used to conduct the study. The minimum inhibitory concentration (MIC) value was measured by the fungal growth inhibition. The results of the MICs were compared with two commercially available reference compounds (Fluconazole and TCMTB). The least active molecule was 3e, but 3b and 3d were found to be the most potent compounds with a similar activity for all strains. Candida albicans was the most sensitive one. In contrast, Aspergillus niger was resistant. Ecotoxicity of gemini 3e was assessed: the commercial formulation (TCMTB) was between three and four orders of magnitude more toxic than the gemini one for the biological species tested.
