Molecular techniques were used to compare the compositions of the bacterial communities of the 2 following lagoons from the former soda Texcoco Lake, Mexico: the restored Facultativa lagoon and the Nabor Carrillo lagoon. Ribosomal intergenic spacer analysis (RISA) revealed that bacterial communities of the 2 lagoons were different and presented a relatively low diversity. Clone libraries of 16S rDNA genes were constructed, and significant phylotypes were distinguished by restriction fragment length ...

Resumen. El cáncer de pulmón es una de las principales causas de mortalidad alrededor del mundo. Su historia natural, con la manifestación de síntomas en etapas avanzadas y el retraso en su diagnóstico hacen que una gran proporción de pacientes se diagnostiquen en estadios tardíos de la enfermedad, lo que hace muy complicado el tratamiento exitoso de la misma. De esto deriva la importancia de dar origen a recomendaciones basadas en evidencia para soportar la toma de decisiones clínicas por parte ...

Entamoeba histolytica trophozoites recovered from the host-parasite interface during abscess development obtain different stimuli compared with long-term cultured cells. In order to have a better understanding about the mechanisms in which the 140 kDa fibronectin (FN)-binding molecule ( Eh FNR) is involved during the invasive process, we decided to compare the regulation process of this molecule among long-term cultured trophozoites, FN-stimulated trophozoites, and trophozoites recently recovered from ...

Describe the anatomical changes and tumor displacement due to a rapid response of a patient's small cell lung cancer (SCLC) during definitive chemoradiotherapy (CRT).The treatment for SCLC is based on CRT. If interfractional changes during RT are incorrectly assessed they might compromise adequate coverage of the tumor or increase dose to organs at risk. Image guided RT with cone-beam computed tomography (CBCT) allows to identify daily treatment variations.Describe a SCLC case with rapid changes in ...

Objectives Stereotactic Ablative Radiotherapy (SABR) has shown high rates of local control and prolonged survival in early-stage non-small cell lung cancer (NSCLC), though its role in oligometastatic disease is undefined. This study aimed to evaluate SABR as a local consolidative therapy (LCT) in oligometastatic NSCLC patients. Methods In this prospective, single-arm phase 2 trial, we sought to evaluate SABR in patients with stage IV NSCLC, with ≤ five lesions, including the primary tumor. Patients received ...

Helicobacter pylori has been recognized as a major gastric pathogen. The objective of this study was to assess the diagnostic value of common clinical tests to detect H. pylori infection, by comparison with PCR. Serum and gastric biopsy specimens from 106 dyspeptic patients were examined. Serology was performed with Pyloriset Dry test, and biopsies were examined histologically, for rapid urease activity and PCR amplification of an ureA gene segment of H. pylori. PCR primers were specific for H. ...

Since Pancharatnam’s 1956 discovery of optical geometric phase and Berry’s 1984 discovery of geometric phase in quantum systems, researchers analyzing geometric phase have focused almost exclusively on algebraic approaches using the Jones calculus, or on spherical trigonometry approaches using the Poincaré sphere. The abstracted mathematics of the former and the abstracted geometry of the latter obscure the physical mechanism that generates geometric phase. We show that optical geometric phase derives ...

Background Different prognostic scales exist in patients with brain metastasis, particularly in lung cancer. The Graded Prognostic Assessment for lung cancer using molecular markers (Lung-molGPA index) for brain metastases is a powerful prognostic tool that effectively identifies patients at different risks. However, these scales do not include perilesional edema diameter (PED) associated with brain metastasis. Current evidence suggests that PED might compromise the delivery and efficacy of radiotherapy ...

In an effort to improve the knowledge about the rules which direct the effect of the early ORF sequences on translation efficiency, we have analyzed the effect of pairs of the six arginine codons at the second and third positions on the expression of lacZ variants. Whereas the pairs of identical AGA or AGG codons were favorable for the gene expression, identical pairs of each of the four CGN codons were very inefficient. This result was unexpected because tandems of AGA or AGG codons located in ...

While Pancharatnam discovered the geometric phase in 1956, his work was not widely recognized until its endorsement by Berry in 1987, after which it received wide appreciation. However, because Pancharatnam's paper is unusually difficult to follow, his work has often been misinterpreted as referring to an evolution of states of polarization, just as Berry's work focused on a cycle of states, even though this consideration does not appear in Pancharatnam's work. We walk the reader through Pancharatnam' ...

The lack of information about Chagas disease in Mexico, as well as the controversy concerning its importance, was the basis for the seroprevalence study of Trypanosoma cruzi in the National Seroepidemiology Survey (NSS).

Unfortunately the NSS was not a very good information source for the study of trypanosomiasis americana, because its coverage in the ...
