Bounds for Lepton Flavor Violation and the Pseudoscalar Higgs in the General Two Higgs Doublet Model using g−2g-2 muon factor

Current experimental data from the $g-2$ muon factor, seems to show the necessity of physics beyond the Standard Model (SM), since the difference between SM and experimental predictions is 2.6$\sigma$. In the framework of the General Two Higgs Doublet Model (2HDM), we calculate the muon anomalous magnetic moment to get lower and upper bounds for the Flavour Changing (FC) Yukawa couplings in the leptonic sector. We also obtain lower bounds for the mass of the pseudoscalar Higgs ($m_{A^0}$) as a function of the parameters of the model.Comment: 12 pages, RevTex4, 5 figures.

Interplay between SUMOylation and NEDDylation regulates RPL11 localization and function

The ribosomal protein L11 (RPL11) integrates different types of stress into a p53-mediated response. Here, we analyzed the impact of the ubiquitin-like protein SUMO on the RPL11-mouse double-minute 2 homolog-p53 signaling. We show that small ubiquitin-related modifier (SUMO)1 and SUMO2 covalently modify RPL11. We find that SUMO negatively modulates the conjugation of the ubiquitin-like protein neural precursor cell-expressed developmentally downregulated 8 (NEDD8) to RPL11 and promotes the translocation of the RP outside of the nucleoli. Moreover, the SUMO-conjugating enzyme, Ubc9, is required for RPL11-mediated activation of p53. SUMOylation of RPL11 is triggered by ribosomal stress, as well as by alternate reading frame protein upregulation. Collectively, our data identify SUMO protein conjugation to RPL11 as a new regulator of the p53-mediated cellular response to different types of stress and reveal a previously unknown SUMO-NEDD8 interplay.-El Motiam, A., Vidal, S., de la Cruz-Herrera, C.

A stromal cell niche sustains ILC2-mediated type-2 conditioning in adipose tissue.

Group-2 innate lymphoid cells (ILC2), type-2 cytokines, and eosinophils have all been implicated in sustaining adipose tissue homeostasis. However, the interplay between the stroma and adipose-resident immune cells is less well understood. We identify that white adipose tissue-resident multipotent stromal cells (WAT-MSCs) can act as a reservoir for IL-33, especially after cell stress, but also provide additional signals for sustaining ILC2. Indeed, we demonstrate that WAT-MSCs also support ICAM-1-mediated proliferation and activation of LFA-1-expressing ILC2s. Consequently, ILC2-derived IL-4 and IL-13 feed back to induce eotaxin secretion from WAT-MSCs, supporting eosinophil recruitment. Thus, MSCs provide a niche for multifaceted dialogue with ILC2 to sustain a type-2 immune environment in WAT

Causas directas de muerte en pacientes diabéticos en el Perú, 2017-2020

Background: Diabetes Mellitus type 2 (DM2) constitutes a global public health problem with high morbidity and mortality rate. Studies reported cardiovascular disease as the main direct cause of death in diabetics, while others attributed it to respiratory diseases. However, in our setting, it is still a question. The objective of our study was to determine the main direct causes of death in diabetic patients of Peru. Material and Methods: Observational, descriptive study. We collected the data from the registry of the “Sistema Informático Nacional de Defunciones” (SINADEF) of Peru from 2017 to 2020. We selected the registries whose ICD-10 corresponds to DM2 to describe the characteristics of the deceased, the direct causes of death and the annual trend of the first five causes. Results: The main direct causes of death in diabetic patients were diseases of the respiratory system (28,0%), diseases of the circulatory system (25,4%) and certain infectious and parasitic diseases (15,0%). In addition, the most affected population was males (50,3%), older adults (76,4%) from the coast region (63,6%). The trend was increasing in the first five causes of death, with the greatest slope between 2019 and 2020 for diseases of the respiratory system (rate 1.40 and 2.96) and diseases of the circulatory system (rate 0.98 and 2.86). Conclusions: The main direct causes of death were diseases of the respiratory and circulatory system. The region with the highest number of deaths was the coast. The trend of the top five causes of death was increasing, with a greater slope between 2019 and 2020.Introducción: La Diabetes Mellitus tipo 2 (DM2) constituye un problema de salud pública mundial con elevada tasa de morbimortalidad. Estudios reportaron como principal causa directa de muerte en diabéticos a las enfermedades cardiovasculares, mientras otros atribuyen a las enfermedades respiratorias. Empero, en nuestro medio aún es una interrogante. El objetivo de nuestro estudio fue determinar las principales causas directas de muerte en pacientes diabéticos en Perú. Materiales y métodos: Se realizó un estudio observacional, descriptivo. Recopilamos los datos del registro del Sistema Informático Nacional de Defunciones (SINADEF) de Perú del año 2017 al 2020, seleccionamos los registros cuyo CIE-10 correspondiera a DM2 para describir las características de los fallecidos, las causas directas de defunción y la tendencia anual de las cinco primeras causas. Resultados: Las principales causas directas de muerte en pacientes diabéticos fueron enfermedades del sistema respiratorio (28,0%), enfermedades del sistema circulatorio (25,4%) y ciertas enfermedades infecciosas y parasitarias (15,0%). Además, se evidenció como población más afectada al sexo masculino (50,3%), adultos mayores (76,4%) y la región costa (63,6%). La tendencia fue creciente en las cinco primeras causas de muerte, con mayor pendiente entre 2019 y 2020 para enfermedades del sistema respiratorio (tasa 1,40 y 2,96) y enfermedades del sistema circulatorio (tasa 0,98 y 2,86). Conclusiones: Las principales causas directas de muerte fueron las enfermedades del sistema respiratorio y circulatorio. La región con mayor cantidad de fallecidos fue la costa. La tendencia de las cinco primeras causas de muerte fue creciente, con mayor pendiente entre 2019 y 2020
