Sr. Editor. El desarrollo de una tesis es una modalidad para obtener el grado académico de bachiller o el título profesional de médico cirujano en las universidades peruanas. En su desarrollo, los estudiantes suelen presentar dificultades originadas por deficiencias en sus conocimientos acerca de metodología de la investigación, lectura crítica y redacción científica (1). Por este motivo, se ha...

Background:Squamous cell carcinoma (SCC) is the most common malignancy of the oral cavity, which is highly invasive. Verrucous carcinoma (VC) is the low-grade form of SCC. Epithelial dysplasia (ED) also has a malignant potential. This immunohistochemical (IHC) study aimed to assess angiogenesis and the presence of tumor-associated macrophages (TAMs) in SCC, VC and ED to determi...

Abstract Introduction: There are many studies about the inhibitory effect of the esophageal distention (ED) on gastric motility. Recently, it has been shown that ED decreases the gastric secretions. It is well established that the inhibitory effect of ED is mediated by activation of vago-vagal inhibitory reflex. However, there is not any investigation about the effect of the reflex on the gast...

Si bien es una gran limitante el no haber realizado los exámenes complementarios mencionados (aislamiento viral, los hallazgos histopatológicos en la placenta), hubiese sido de gran valor el aislamiento del virus en aspirado traqueo-bronquial, ya que este es más específico (2). El hallazgo de un PCR positivo en un hisopado nasal dentro del contexto de una pandemia no necesariamente indica que e...

in this paper, we have studied on the solutions of modied kdv equation andalso on the stability of them. we use the tanh method for this investigationand given solutions are good-behavior. the solution is shock wave and can beused in the physical investigations

background: the radiation doses resulting from diagnostic x-ray examinations are routinely measured in terms of entrance surface dose (esd) and effective dose (ed). in this study, for the purpose of radiation protection, the radiation doses received from digital chest x-ray examination were evaluated in terms of esd and ed. material and methods: the ed was calculated by using the mcnp monte car...
