Estandarización del protocolo para elaborar tempeh con diversos granos (y su adaptación a la comida regional mexicana).

Se evaluó el crecimiento del hongo Rhizopus oryzae en diferentes granos, legumbres y semillas para la producción de tempeh, el cual se considera como un superalimento. Los sustratos se sometieron a diversos procesos de cocción, escurrimiento y fermentación, los cuales fueron optimizados de acuerdo a las características del sustrato seleccionado. La fermentación se llevó a cabo mediante la inoculación con la cepa R. oryzae. Sucesivamente, se mezcló el sustrato con el inóculo, y se colocó en bolsas plásticas con cierre hermético, previamente perforadas. Estas fueron incubadas a 35 ºC por un período de 24 a 48 horas. El producto obtenido en las diferentes variantes presentó las características típicas de tempeh de buena calidad

Generation and control of non-local chiral currents in graphene superlattices by orbital Hall effect

Graphene-based superlattices offer a new materials playground to exploit and control a higher number of electronic degrees of freedom, such as charge, spin, or valley for disruptive technologies. Recently, orbital effects, emerging in multivalley band structure lacking inversion symmetry, have been discussed as possible mechanisms for developing orbitronics. Here, we report non-local transport measurements in small gap hBN/graphene/hBN moir\'e superlattices which reveal very strong magnetic field-induced chiral response which is stable up to room temperature. The measured sign dependence of the non-local signal with respect to the magnetic field orientation clearly indicates the manifestation of emerging orbital magnetic moments. The interpretation of experimental data is well supported by numerical simulations, and the reported phenomenon stands as a formidable way of in-situ manipulation of the transverse flow of orbital information, that could enable the design of orbitronic devices.Comment: 5 pages, 5 figures and supplementary informatio

Association between rectal colonisation by Klebsiella pneumoniae carbapenemase-producing K. pneumoniae and mortality: a prospective, observational study.

We evaluated the association of Klebsiella pneumoniae carbapenemase-producing K. pneumoniae (KPC-Kp) rectal colonisation with crude mortality and whether this association is independent of the risk of KPC-Kp infection. This was a prospective cohort study of patients followed-up 90 days after a study of rectal colonisation. Cox regression was used to study the variables associated with crude mortality. Sensitivity analyses for 90-day crude mortality in different subcohorts were performed. A total of 1244 patients (1078 non-colonised and 166 colonised) were included. None of the non-colonised patients and 78 (47.0%) of the colonised patients developed KPC-Kp infection. The 90-day crude mortality was 18.0% (194/1078) in non-colonised patients and 41.6% (69/166) in colonised patients. Rectal colonisation was not associated with crude mortality [hazard ratio (HR) = 1.03, 95% confidence interval (CI) 0.69-1.54; P = 0.85] when the model was adjusted for severe KPC-Kp infection [INCREMENT-CPE score (ICS) > 7]. KPC-Kp infection with ICS > 7 was associated with an increased risk of all-cause mortality (HR = 2.21, 95% CI 1.35-3.63; P = 0.002). In the sensitivity analyses, KPC-Kp colonisation was not associated with mortality in any of the analysed subcohorts, including patients who did not develop KPC-Kp infection (HR = 0.93, 95% CI 0.60-1.43; P = 0.74). KPC-Kp rectal colonisation was not associated with crude mortality. Mortality increased when colonised patients developed severe KPC-Kp infection (ICS > 7). Rectal colonisation was a necessary although insufficient condition to die from a KPC-Kp infection
