A(H3N2) antigenic variation of influenza is associated with low vaccine efficacy in the early 2018 influenza season in Mexico City.

Objectives: We evaluated the VE and the mutations of the viruses present in the Mexican population at the beginning of 2018.

Methods: We diagnosed influenza in outpatients with a high-performance Rapid Influenza Diagnostic Test (RIDT) qRT-PCR. Descriptive statistics were used to describe the study population, while the chi-square test was used to determine clinical variables.

Lesion Length as a Prognosis Marker of Mortality in Patients with Fournier's Gangrene: Proposal of a New Scoring System.

Objective: To assess the prognostic value of mortality of a new system for quantifying the lesion length circumscribed to the genitals and adjacent anatomical areas in patients with Fournier's gangrene.

Methods: An observational, analytical and prospective study in the Urology service of the Arnaldo Milián Castro University Hospital, between January 2007 and December 2019. The sample consisted of 60 patients diagnosed with Fournier's gangrene.

Characterization and Identification of Cryptic Biopeptides in (Wangenh K. Koch) Storage Proteins.

The objective of this research was to identify and characterize the encoded peptides present in nut storage proteins of . It was found, through in silico prediction, proteomic analysis, and MS spectrometry, that bioactive peptides were mainly found in albumin and glutelin fractions. Glutelin was the major fraction with ~53% of the nut storage proteins containing at least 21 peptides with different putative biological activities, including antihypertensives, antioxidants, immunomodulators, protease inhibitors, and inhibitors of cell cycle progression in cancer cells.

Effects of Phosphorylation in Chlamydomonas Centrin Ser 167.

Centrin is a conserved calcium binding protein belonging to the EF-hand superfamily with two independent structural domains. This protein is found to be phosphorylated near the carboxyl terminal end. Our goal was to perform a novel comparative study of phosphorylated and unphosphorylated centrin by Fourier transform infrared (FT-IR) spectroscopy, two-dimensional correlation spectroscopy (2D-COS) analysis and differential scanning calorimetry (DSC).
