Abstract:

Insomnia is one of the most frequently observed sleep disorders, affecting nearly 10% of the general population. It has multiple etiological factors. Recently, it has been reported that EEG abnormalities are associated with insomnia in patients previously diagnosed as idiopathic insomniacs. In addition, transcranial magnetic stimulation (TMS) has shown to be effective in the treatment of disorders characterized by neural hyper-excitability. Method: In the present study, patients with insomnia and EEG abnormalities were submitted to slow repetitive trans-cranial magnetic stimulation, for 15 minutes daily during 10 days. Polysomnographic recordings were performed before and after TMS. Results: The results indicate that the presence of EEG abnormalities significantly decreased after TMS. In addition, most of the sleep parameters showed significant improvement. Conclusions: These data support the notion that TMS is a reliable therapeutic tool for patients affected with abnormalities linked to neuronal hyper-excitability.

Abstract: Evaluación de Bispiribac-sodio en el control de malezas en arroz de temporal. Se establecieron dos experimentos en Los Naranjos, Veracruz, México, con el objeto de evaluar la eficiencia biológica y el efecto fitotóxico del herbicida postemergente bispiribac-sodio, solo y en mezcla con otros herbicidas, para controlar malezas en el cultivo de arroz de temporal. Un experimento fue establecido el 13 de junio de 1999 el segundo el 9 de junio del 2000 con arroz de la variedad Milagro Filipino, a 100 kg/ha. El dise o experimental fue de bloques completos al azar con ocho tratamientos para el primero y seis para el segundo, y cuatro repeticiones de cada uno. En 1999, el control de malezas se evaluó a los 15, 30 y 105 días después de la aplicación (DDA) y en 2000 a los 15, 30 y 45 DDA. En ambos experimentos, la toxicidad se evaluó a los 15 y 30 DDA. Las especies de malezas dominantes fueron el zacate de agua [Echinochloa colona (L.) Link.], el pelillo (Cyperus iria L.) y el zacate frente de toro [Digitaria ciliaris (Retz.) Koel]. Bispiribac-sodio afectó solamente plantas de malezas emergidas; este herbicida controló eficientemente al pelillo a 15 g/ha, al zacate de agua a 22 g/ha y solamente tuvo un control parcial del zacate frente de toro. Al mezclar el bispiribac- sodio con clomazone o tiobencarbo, se incrementó el control de los zacates y se obtuvo un efecto herbicida residual. El bispiribac-sodio fue altamente selectivo al arroz.
First record of salamander predation by a Liophis (Wagler, 1830) snake in the Venezuelan Andes

Acta Herpetologica , 2009,
Abstract: Information available so far is exceedingly meagre about the diet of the snakes included in the genus Liophis, one of the most diverse groups that inhabit terrestrial ecosystems of South America. For the first time is documented the predation of a salamander by Liophis from Venezuela, including a brief overview on the alteration of montane and submontane Andean ecosystem and their effect on the natural dynamic.

Abstract: Background: The poor prognosis of patients with high-grade glioma multiform (GBM) has led investigators to the search of new therapeutic strategies. Current treatment includes surgery when possible, radiotherapy and chemotherapy. Molecular-targeted therapies are in the process of clinical testing, and promising agents include monoclonal antibodies. Our study examined the antitumor activity of three different single therapies in nude mice bearing both subcutaneous and orthotopic brain xenografts of the U87MG human GBM cell line. Methods: Cell culture, Histology, Immunohistochemistry, Animal experiments, Statistical analysis. Results: Different groups of treatment included nimotuzumab, a humanized monoclonal antibody that inhibits the EGFR tyrosine kinase activity, or total body irradiation, or the chemotherapeutic agent temozolomide (TMZ). For the control group animals received saline solution instead of the antibody. For the subcutaneous model, only nimotuzumab or TMZ produced a significant delay in tumor growth. In the intracranial model, unlike TMZ, the systemic administration of the antibody did not reduce the tumor growth, despite both therapies inhibited the formation of microsatellites in the brain of mice. The antitumor activity of nimotuzumab was accompanied by a decrease in the microvessel density and the proliferative activity of tumor cells. TMZ only inhibited the tumor cell proliferation but not the formation of new tumor-associated microvessels in xenografts. For radiation therapy, neither antiproliferative nor antiangiogenic activity was found, in accordance with the lack of antitumor activity. Only nimotuzumab reduced the frequency of chemo and radioresistant CD133+ population. Conclusion: Our results illustrate the potential efficacy of nimotuzumab as a single agent against an EGFR-amplified human GBM, a tumor resistant to the therapy with all well-known forms of treatment.

Abstract: Thyroid nodules are a major health problem worldwide. The prevalence of palpable thyroid nodules in the general population is approximately 5% in women and 1% in men living in parts of the world with sufficient iodine. High resolution neck and thyroid ultrasound can detect thyroid nodules in a significant proportion of randomly selected individuals, with higher frequencies in women and the elderly population. The importance of thyroid nodules lies in the need to rule out cancer. The majority of thyroid nodules are benign, clinically irrelevant, and can be safely managed with a good surveillance program. The detection and diagnosis of differentiated thyroid cancer have evolved over the years with increased use of high resolution cervical and thyroid ultrasound, fine needle aspiration biopsy (FNAB), molecular testing, and thyroglobulin as a serum tumor marker. An algorithm that utilizes high resolution ultrasound and, when indicated, FNAB, and molecular testing for the diagnosis of thyroid nodules, facilitates a personalized, risk-based protocol that promotes high-quality care and minimizes cost and unnecessary testing. Our paper reviews the current, evidence-based management of newly diagnosed thyroid nodules.

Abstract: Se determinóla cinética de la degradación ruminal de la materia seca, laproteína cruda y el extracto etéreo en las harinas de pescado,carne y hueso y tortave. Con base en los resultados de degradación a 48 horas de incubación ruminal, se determinó enforma biológica los contenidos digeribles reales de la proteí-na y grasa digerida, haciendo más precisa la medición del total de nutrientes digeribles y los valores de energía digestibley neta de los alimentos que por el método químico. Los valores de energía neta para producción fueron de 2,02, 1,66 y2,60 Mcals/kg en la harina de pescado, harina de carne y hue-so y la tortave, respectivamente. La fracción de proteína soluble (A) fue alta en la harina de pescado (75,29%), media enla harina de carne y hueso (46,83%) y más baja en la harinade tortave (25,75%), con una fracción degradable (B) de10,62, 27,66 y 42,06%; así como una fracción insoluble (C)de 14,09, 25,51, y 32,19%, respectivamente. La proteína de-gradada en el rumen fue de 83,23, 66,25 y 51,98%, en el mismo orden de presentación anterior. Los contenidos de proteína cruda efectivamente retenida por el animal durante elproceso de digestión total, fueron de 53,29, 51,86 y 42,05%para la harina de pescado, harina de carne y hueso y la harina de tortave.
