A detailed quantitative analysis of circulating T peripheral and follicular helper lymphocytes in patients with rheumatoid arthritis and systemic lupus erythematosus.

Introduction And Objective: Peripheral and follicular helper T lymphocytes (Tph and Tfh, respectively) have an important role in B cell immune responses and the pathogenesis of rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE). Although several studies on the number of Tph and Tfh cells in these conditions have been published, different phenotypes have been employed for their analysis. In this study, we assessed the levels and function of Tph and Tfh cells in blood samples from patients with RA and SLE by using an extended immunophenotype.

Myroides species, pathogenic spectrum and clinical microbiology sight in Mexican isolates.

Introduction: Myroides is a bacterial genus of opportunistic bacteria responsible for diverse infections including in the skin and soft tissues, urinary tract, cardiovascular system, and bacteremia, although the incidence of its reported infections is low, it is increasing, likely due the use of better bacterial identification methods, but also perhaps due an increase in its prevalence. In addition, their pathogenic role is limited in terms of reporting their microbial physiology, so the present work provides information in this regard in addition to the information that is available in the international literature.

Objective: To describe the microbiological and genetic characteristics of seven different Myroides spp.

Nursing Interventions Related to the Need for Oxygenation in Severe COVID-19 Disease in Hospitalized Adults: A Retrospective Study.

Unlabelled: COVID-19 affects the respiratory system, reducing the oxygen saturation level, leading to hypoxemia and increasing the metabolic oxygenation need.

Objective: To describe the nursing interventions related to the need for oxygenation in hospitalized adults with severe COVID-19 disease in the Intensive Care Unit.

Method: This was an observational, retrospective and descriptive study in a population of 2205 patients with a convenience sample of = 430 and based on the North American Nursing Diagnosis Association (NANDA), the Nursing Interventions Classification (NIC) and the Nursing Outcomes Classification (NOC).

Cationic Carbosilane Dendrimers for Apmnkq2 Aptamer Transfection in Breast Cancer: An Alternative to Traditional Transfectants.

Transfection efficiency is a critical parameter in gene therapy and molecular biology, representing the success rate at which nucleic acids are introduced and expressed in target cells. The combination of aptamers with nanotechnology-based delivery systems has demonstrated remarkable improvements in the transfection efficiency of therapeutic agents and holds significant potential for advancing gene therapy and the development of targeted treatments for various diseases, including cancer. In this work, cationic carbosilane dendritic systems are presented as an alternative to commercial transfection agents, demonstrating an increase in transfection efficiency when used for the internalization of apMNKQ2, an aptamer selected against a target in cancer.

Search for Rare b→dℓ^{+}ℓ^{-} Transitions at Belle.

We present the results of a search for the b→dℓ^{+}ℓ^{-} flavor-changing neutral-current rare decays B^{+,0}→(η,ω,π^{+,0},ρ^{+,0})e^{+}e^{-} and B^{+,0}→(η,ω,π^{0},ρ^{+})μ^{+}μ^{-} using a 711  fb^{-1} data sample that contains 772×10^{6}  BB[over ¯] events. The data were collected at the ϒ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e^{+}e^{-} collider. We find no evidence for signal and set upper limits on branching fractions at the 90% confidence level in the range (3.
