PalC, One of Two Bro1 Domain Proteins in the Fungal pH Signalling Pathway, Localizes to Cortical Structures and Binds Vps32
PalC, distantly related to Saccharomyces cerevisiaeperipheral endosomal sorting complexes required for transport III (ESCRT-III) component Bro1p and one of six Aspergillus nidulanspH signalling proteins, contains a Bro1 domain. Green fluorescent protein (GFP)-tagged PalC is recruited to plasma membrane-associated punctate structures upon alkalinization, when pH signalling is active. PalC recruitment to these structures is dependent on the seven transmembrane domain (7-TMD) receptor and likely pH sensor PalH. PalC is a two-hybrid interactor of the ESCRT-III Vps20/Vps32 subcomplex and binds Vps32 directly. This binding is largely impaired by Pro439Phe, Arg442Ala and Arg442His substitutions in a conserved region mediating interaction of Bro1p with Vps32p, but these substitutions do not prevent cortical punctate localization, indicating Vps32 independence. In contrast, Arg442Î impairs Vps32 binding and prevents PalC-GFP recruitment to cortical structures. pH signalling involves a plasma membrane complex including the 7-TMD receptor PalH and the arrestin-like PalF and an endosomal membrane complex involving the PalB protease, the transcription factor PacC and the Vps32 binding, Bro1-domain-containing protein PalA. PalC, which localizes to cortical structures and can additionally bind a component of ESCRT-III, has the features required to bridge these two entities. A likely S. cerevisiaeorthologue of PalC has been identified, providing the basis for a unifying hypothesis of gene regulation by ambient pH in ascomycetes

Dietary αâLinolenic Acid, Marine Ïâ3 Fatty Acids, and Mortality in a Population With High Fish Consumption: Findings From the PREvenciĂłn con DIeta MEDiterrĂĄnea (PREDIMED) Study
Background: Epidemiological evidence suggests a cardioprotective role of αâlinolenic acid (ALA), a plantâderived Ïâ3 fatty acid. It is unclear whether ALA is beneficial in a background of high marine Ïâ3 fatty acids (longâchain nâ3 polyunsaturated fatty acids) intake. In persons at high cardiovascular risk from Spain, a country in which fish consumption is customarily high, we investigated whether meeting the International Society for the Study of Fatty Acids and Lipids recommendation for dietary ALA (0.7% of total energy) at baseline was related to allâcause and cardiovascular disease mortality. We also examined the effect of meeting the society's recommendation for longâchain nâ3 polyunsaturated fatty acids (â„500 mg/day). Methods and Results: We longitudinally evaluated 7202 participants in the PREvenciĂłn con DIeta MEDiterrĂĄnea (PREDIMED) trial. Multivariableâadjusted Cox regression models were fitted to estimate hazard ratios. ALA intake correlated to walnut consumption (r=0.94). During a 5.9ây followâup, 431 deaths occurred (104 cardiovascular disease, 55 coronary heart disease, 32 sudden cardiac death, 25 stroke). The hazard ratios for meeting ALA recommendation (n=1615, 22.4%) were 0.72 (95% CI 0.56â0.92) for allâcause mortality and 0.95 (95% CI 0.58â1.57) for fatal cardiovascular disease. The hazard ratios for meeting the recommendation for longâchain nâ3 polyunsaturated fatty acids (n=5452, 75.7%) were 0.84 (95% CI 0.67â1.05) for allâcause mortality, 0.61 (95% CI 0.39â0.96) for fatal cardiovascular disease, 0.54 (95% CI 0.29â0.99) for fatal coronary heart disease, and 0.49 (95% CI 0.22â1.01) for sudden cardiac death. The highest reduction in allâcause mortality occurred in participants meeting both recommendations (hazard ratio 0.63 [95% CI 0.45â0.87]). Conclusions: In participants without prior cardiovascular disease and high fish consumption, dietary ALA, supplied mainly by walnuts and olive oil, relates inversely to allâcause mortality, whereas protection from cardiac mortality is limited to fishâderived longâchain nâ3 polyunsaturated fatty acids.

Consumption in Spain during the state of alert: an analysis based on payment card spending
ArtĂculo de revistaIn recent years, information on the usage of cards as a means of payment has been increasingly used as an indicator of private consumption. The advantages of such information include its daily frequency and the short time lag from the moment of spending until it becomes available. This article uses this indicator to analyse Spanish household consumption since the state of alert was declared in mid-March and to explore the corresponding determinants. Indeed, the drop in consumption during the COVID-19 health crisis has been far greater than that suggested by the usual determinants, indicating that other factors could largely explain the developments observed. Included here are the greater uncertainty as to the course of the disease and its economic repercussions, and the restrictions on peopleâs movement and on various economic activities during the state of alert. Card payment data can be used to investigate the importance of social distancing measures when explaining the developments observed in consumption since midMarch. The article identifies that the indicators of payment card usage show a high correlation with the course of the restrictions on movement and activity. The information available also shows how in-person purchases were replaced by online shopping during lockdown
Gerri distrofia muskularra Gipuzkoan
Gracias a los avances producidos en la genĂ©tica molecular, el concepto de Distro a Muscular Lumbar (LGMD) estĂĄ cambiando rĂĄpidamente. Se han descrito diferentes loci y ha quedado probado que el sĂndrome de Distro a muscular Lumbar es heterogĂ©neo. Hemos realizado un examen epidemiolĂłgico en Gipuzkoa y hemos encontrado la prevalencia mayor de LGMD descrita hasta la fecha: 69/106.

Evolución del consumo en España durante la vigencia del estado de alarma: un anålisis a partir del gasto con tarjetas de pago
ArtĂculo de revistaLa informaciĂłn acerca de la utilizaciĂłn de las tarjetas como medio de pago constituye un indicador del consumo privado de uso creciente en los Ășltimos años. Entre sus ventajas se incluyen su frecuencia diaria y su disponibilidad con escaso retraso respecto al momento en el que se incurre en el gasto. En el artĂculo se utiliza este indicador para analizar la evoluciĂłn del consumo de los hogares españoles desde la declaraciĂłn del estado de alarma (mediados de marzo) y para explorar sus factores explicativos. En efecto, la caĂda del consumo durante la crisis sanitaria del Covid-19 ha sido muy superior a la que sugerirĂan sus determinantes habituales, lo que apunta a que otros factores âcomo el aumento de la incertidumbre en torno al curso de la enfermedad y a sus repercusiones econĂłmicas, y las restricciones a la movilidad personal y a diversas actividades econĂłmicas durante el perĂodo de vigencia del estado de alarmaâ explicarĂan en gran medida los desarrollos observados. El empleo de los datos acerca del uso de las tarjetas como medio de pago permite indagar en la relevancia de las medidas de distanciamiento social a la hora de explicar los desarrollos observados en el consumo desde mediados de marzo. El artĂculo encuentra que los indicadores del uso de tarjetas de pago muestran una elevada correlaciĂłn con la evoluciĂłn de las limitaciones a la movilidad y a la actividad. La informaciĂłn disponible muestra ademĂĄs cĂłmo se produjo una sustituciĂłn de compras presenciales por compras por Internet durante el confinamiento
Role of Postbiotics in Diabetes Mellitus: Current Knowledge and Future Perspectives
In the last decade, the gastrointestinal microbiota has been recognised as being essential for health. Indeed, several publications have documented the suitability of probiotics, prebiotics, and symbiotics in the management of different diseases such as diabetes mellitus (DM). Advances in laboratory techniques have allowed the identification and characterisation of new biologically active molecules, referred to as âpostbioticsâ. Postbiotics are defined as functional bioactive compounds obtained from food-grade microorganisms that confer health benefits when administered in adequate amounts. They include cell structures, secreted molecules or metabolic by-products, and inanimate microorganisms. This heterogeneous group of molecules presents a broad range of mechanisms and may exhibit some advantages over traditional âbioticsâ such as probiotics and prebiotics. Owing to the growing incidence of DM worldwide and the implications of the microbiota in the disease progression, postbiotics appear to be good candidates as novel therapeutic targets. In the present review, we summarise the current knowledge about postbiotic compounds and their potential application in diabetes management. Additionally, we envision future perspectives on this topic. In summary, the results indicate that postbiotics hold promise as a potential novel therapeutic strategy for DM
