RESUMO
By analyzing a mouse Interspecific Recombinant Congenic Strain (IRCS), we previously identified a quantitative trait locus (QTL), called Mafq1 on mouse chromosome 1, that is associated with male hypofertility and ultrastructural sperm abnormalities. Within this locus, we identified a new candidate gene that could be implicated in a reproductive phenotype: Tex44 (Testis-expressed protein 44). We thus performed a CRISPR/Cas9-mediated complete deletion of this gene in mice in order to study its function. Tex44-KO males were severely hypofertile in vivo and in vitro due to a drastic reduction of sperm motility which itself resulted from important morphological sperm abnormalities. Namely, Tex44-KO sperm showed a disorganized junction between the midpiece and the principal piece of the flagellum, leading to a 180° flagellar bending in this region. In addition, the loss of some axonemal microtubule doublets and outer dense fibers in the flagellum's principal piece has been observed. Our results suggest that, in mice, TEX44 is implicated in the correct set-up of the sperm flagellum during spermiogenesis and its absence leads to flagellar abnormalities and consequently to severe male hypofertility.

Living with chronic kidney disease (CKD) is associated with hardships for patients and their care partners. Empowering patients and their care partners, including family members and friends involved in their care, may help minimize the burden and consequences of CKD-related symptoms to enable increased life participation. There is a need to broaden the focus on living well with kidney disease and reengagement in life, including emphasis on the patient being in control. The World Kidney Day (WKD) Joint Steering Committee has declared 2021 the year of "Living Well with Kidney Disease" in an effort to increase education about and awareness of the important goal of patient empowerment and life participation. This calls for the development and implementation of validated patient-reported outcome measures to assess and address areas of life participation in routine care. It could be supported by regulatory agencies as a metric for quality care or to support labeling claims for medicines and devices. Funding agencies could establish targeted calls for research that address the priorities of patients. Patients with kidney disease and their care partners should feel supported to live well through concerted efforts by kidney care communities, including during pandemics. In the overall wellness program for patients with kidney disease, the need for prevention should be reiterated. Early detection with prolonged course of wellness despite kidney disease, after effective secondary and tertiary prevention programs, should be promoted. WKD 2021 continues to call for increased awareness of the importance of preventive measures across populations, professionals, and policy makers, applicable to both developed and developing countries.

Thanks to the analysis of an Interspecific Recombinant Congenic Strain (IRCS), we previously defined the Mafq1 quantitative trait locus as an interval on mouse Chromosome 1 associated with male hypofertility and ultrastructural abnormalities. We identified the Spermatogenesis associated protein 3 gene (Spata3 or Tsarg1) as a pertinent candidate within the Mafq1 locus and performed the CRISPR-Cas9 mediated complete deletion of the gene to investigate its function. Male mice deleted for Spata3 were normally fertile in vivo but exhibited a drastic reduction of efficiency in in vitro fertilization assays. Mobility parameters were normal but ultrastructural analyses revealed acrosome defects and an overabundance of lipids droplets in cytoplasmic remnants. The deletion of the Spata3 gene reproduces therefore partially the phenotype of the hypofertile IRCS strain.

In dogs, tick infestation can cause damage ranging from a simple skin irritation to severe diseases and/or paralysis leading to animal death. For example, Ixodes ricinus and I. scapularis are among the tick species incriminated the most in the transmission of Borrelia burgdorferi, the agent of human and canine Lyme borreliosis (LB). In this study, we aimed to compare the efficacy of two products designed for dogs-an oral systemic ectoparasiticide and a topical repellent ectoparasiticide-against the acquisition of B. burgdorferi by adult I. scapularis and I. ricinus using an ex vivo model. Thirty-two beagle dogs were included in a parallel-group-designed, randomized, single-center, negative-controlled efficacy study. The dogs were allocated to three groups based on gender and body weight: a fluralaner (F, Bravecto®) treatment group (n = 8), administered a single oral treatment on day 0 at the recommended dose; a dinotefuran-permethrin-pyriproxyfen (DPP, Vectra® 3D) treatment group (n = 8), topically treated on day 56 at the recommended dose; and an untreated control group (n = 16). Blood and hair were collected from each dog on days 58, 63, 70, 77, and 84. Hair was added to the silicone-based membrane separating two glass chambers forming the feeding unit (FU). Chamber 1 was filled with blood spiked with B. burgdorferi sensu stricto, strain B31 (105 cells/mL). Chamber 2, glued below chamber 1, was seeded with 20 adult I. scapularis or I. ricinus. The FUs (n = 240) were incubated at 37 °C with a humidity >90%. Tick survival, attachment, and feces presence were observed from 1 h up to 72 h after tick seeding. The uptake of B. burgdorferi was determined in ticks using nested polymerase chain reaction (nPCR). The acaricidal efficacy of DPP-treated hair was 100% within 1 h of tick release on every study day for both I. ricinus and I. scapularis. The speed of kill associated with DPP was sufficiently fast to prevent tick attachment and engorgement, and, consequently, to prevent the acquisition of B. burgdorferi. In the F-treated group, the acaricidal efficacy observed at 12 h, throughout the study, was <20% and <28% for I. scapularis and I. ricinus, respectively. Furthermore, tick feces were observed in the FUs, and several female ticks (I. scapularis (n = 55) and I. ricinus (n = 94)) tested positive for B. burgdorferi. The results provide proof of concept for the use of an ex vivo model based on an artificial feeding system to compare two ectoparasiticides against the acquisition of B. burgdorferi by I. ricinus and I. scapularis. In addition, our results demonstrate the superiority of DPP compared to F in the speed of acaricidal activity against ticks, as well as in preventing the acquisition of B. burgdorferi.
RESUMO
Traditional thin sectioning microscopy of large bone and dental tissue samples using demineralization may disrupt structure morphologies and even damage soft tissues, thus compromising the histopathological investigation. Here, we developed a synergistic and original framework on thick sections based on wide-field multi-fluorescence imaging and spectral Principal Component Analysis (sPCA) as an alternative, fast, versatile, and reliable solution, suitable for highly mineralized tissue structure sustain and visualization. Periodontal 2-mm thick sections were stained with a solution containing five fluorescent dyes chosen for their ability to discriminate close tissues, and acquisitions were performed with a multi-zoom macroscope for blue, green, red, and NIR (near-infrared) emissions. Eigen-images derived from both standard scaler (Std) and Contrast Limited Adaptive Histogram Equalization (Clahe) pre-preprocessing significantly enhanced tissue contrasts, highly suitable for histopathological investigation with an in-depth detail for sub-tissue structure discrimination. Using this method, it is possible to preserve and delineate accurately the different anatomical/morphological features of the periodontium, a complex tooth-supporting multi-tissue. Indeed, we achieve characterization of gingiva, alveolar bone, cementum, and periodontal ligament tissues. The ease and adaptability of this approach make it an effective method for providing high-contrast features that are not usually available in standard staining histology. Beyond periodontal investigations, this first proof of concept of an sPCA solution for optical microscopy of complex structures, especially including mineralized tissues opens new perspectives to deal with other chronic diseases involving complex tissue and organ defects. Overall, such an imaging framework appears to be a novel and convenient strategy for optical microscopy investigation.

Vivir con enfermedad renal crónica se asocia con penurias para el paciente y sus cuidadores. Su empoderamiento, que incluye a los familiares o los amigos comprometidos en los cuidados, puede ayudar a minimizar la carga y las consecuencias de los síntomas asociados a la enfermedad renal crónica y permitir las actividades cotidianas. Es necesario ampliar el foco sobre vivir bien con la enfermedad renal y reinsertarse en la vida, con énfasis en que los pacientes tengan sus controles. El World Kidney Day (WKD) Joint Steering Committee (Comité Directivo Conjunto del Día Mundial del Riñón) ha declarado al 2021 como el año de "Vivir bien con enfermedad renal" en un esfuerzo por aumentar la educación y la conciencia sobre el objetivo importante del empoderamiento del paciente y su participación en la vida. Esto reclama el desarrollo e implementación de evaluaciones validadas de la evolución referida por los pacientes para medir e incluir las áreas de participación en la vida en los cuidados de rutina. Esto podría ser respaldado por las agencias reguladoras como una métrica de la calidad de la atención o para respaldar las declaraciones de etiquetado de medicamentos y dispositivos. Las agencias financiadoras podrían establecer llamados dirigidos a investigar las prioridades de los pacientes. Los pacientes con enfermedad renal y sus cuidadores deberían sentirse respaldados para vivir bien mediante esfuerzos concertados de los servicios de atención renal, incluso durante las pandemias. En el programa de bienestar general para pacientes con enfermedad renal, se debe reiterar la necesidad de prevención. Se debe promover la detección precoz acompañada de un curso prolongado de bienestar a pesar de la enfermedad renal, después de programas de prevención efectiva secundaria y terciaria. El WKD 2021 continua su reclamo de aumentar la conciencia de la importancia de las medidas preventivas entre las comunidades, los profesionales y los responsables de las políticas, aplicable tanto a los países desarrollados como a aquellos en vías de desarrollo.
