In addition, undetermined mechanistic aspects of the DNA enzymatic pathways driven by this vital yet enigmatic chromosomal surveillance and repair apparatus will be discussed. In particular, novel and putative models of DNA damage recognition will be considered and comparisons will be made between the modes of action of the Rad50 protein and other related ATPases of the overarching SMC superfamily.The transport of histones from the cytoplasm to the nucleus of the cell, through the nuclear membrane, is a cellular process that regulates the supply of new histones in the nucleus and is key for DNA replication and transcription. Nuclear import of histones is mediated by proteins of the karyopherin family of nuclear transport receptors. Karyopherins recognize their cargos through linear motifs known as nuclear localization/export sequences or through folded domains in the cargos. Karyopherins interact with nucleoporins, proteins that form the nuclear pore complex, to promote the translocation of their cargos into the nucleus. When binding to histones, karyopherins not only function as nuclear import receptors but also as chaperones, protecting histones from non-specific interactions in the cytoplasm, in the nuclear pore and possibly in the nucleus. Studies have also suggested that karyopherins might participate in histones deposition into nucleosomes. In this review we describe structural and biochemical studies from the last two decades on how karyopherins recognize and transport the core histone proteins H3, H4, H2A and H2B and the linker histone H1 from the cytoplasm to the nucleus, which karyopherin is the major nuclear import receptor for each of these histones, the oligomeric state of histones during nuclear import and the roles of post-translational modifications, histone-chaperones and RanGTP in regulating these nuclear import pathways.Biomolecular condensates comprise a diverse and ubiquitous class of membraneless organelles. Condensate assembly is often described by liquid-liquid phase separation. While this process explains many key features, it cannot account for the compositional or architectural complexity that condensates display in cells. Recent work has begun to dissect the rich network of intermolecular interactions that give rise to biomolecular condensates. Here, we review the latest results from theory, simulations and experiments, and discuss what they reveal about the structure-function relationship of condensates.

Auto-augmentation mastopexy after implant removal has been described as a possible alternative for women who do not opt for implant replacement and declined major reconstructive surgery.

Our study aimed to evaluate patient satisfaction after auto-augmentation mastopexy relative to the final breast volume and to assess the role of fat grafting on patients' satisfaction and quality of life using the BREAST-Q questionnaire.

Forty-seven breasts from 28 patients who underwent implant removal and auto-augmentation mastopexy were reviewed; 9 patients (Group 1) were primarily treated with several fat grafting sessions with subsequent auto-augmentation, 5 (Group2) were treated primarily with auto-augmentation, but afterward expressed a wish for breast augmentation by lipofilling, and 14 patients (Control) had only auto-augmentation.

Group maintained their breast volume, showed significant improvement of breast satisfaction, psychosocial wellbeing, and contented breast surgery outcomes (p = 0.01, ˂0.01 and ˂0.01 respectively). However, the physical wellbeing of this group, as well as response to final cup size or interaction parameters, did not improve (p = 0.06). In Group 2, all except one patient had breast volume reduction to A cup, as was the case with one-third of the patients in the Control Group 3 (Group 3A, n = 5) who scored lower, and thus, less satisfied with the breast auto-augmentation than Group 3B who achieved final bigger cup sizes (p ˂ 0.01).

Auto-augmentation mastopexy resulted in substantial improvement of the parameters measured by BREAST-Q. Thus, the combined auto-augmentation mastopexy and lipofilling provided a better alternative treatment after breast implant removal.

When rare missense variants are clinically interpreted as to their pathogenicity, most are classified as variants of uncertain significance (VUS). GLPG0187 Although functional assays can provide strong evidence for variant classification, such results are generally unavailable. Multiplexed assays of variant effect can generate experimental 'variant effect maps' that score nearly all possible missense variants in selected protein targets for their impact on protein function. However, these efforts have not always prioritized proteins for which variant effect maps would have the greatest impact on clinical variant interpretation.

Here, we mined databases of clinically interpreted variants and applied three strategies, each building on the previous, to prioritize genes for systematic functional testing of missense variation. The strategies ranked genes (i) by the number of unique missense VUS that had been reported to ClinVar; (ii) by movability- and reappearance-weighted impact scores, to give extra weight to reappearing, movable VUS and (iii) by difficulty-adjusted impact scores, to account for the more resource-intensive nature of generating variant effect maps for longer genes. Our results could be used to guide systematic functional testing of missense variation toward greater impact on clinical variant interpretation.

Patients with coronavirus disease 2019 (COVID-19) have thromboembolic complications. Assessment of coagulation and other markers could be useful to understand their coagulopathy.

We performed a retrospective study of inflammatory and coagulation parameters, including prothrombin fragment 1.2 (PF1.2), thrombin-antithrombin complexes (TATs), fibrin monomers, and D-dimer, in hospitalized patients with COVID-19. We compared the markers in patients with thrombosis, admission to the intensive care unit (ICU), and poor outcome.

Of the 81 patients, 9 (11%) experienced an acute thrombotic event (4 with pulmonary embolism, 3 with venous thrombosis, and 2 with stroke). PF1.2 was elevated in 32 (39%) patients, TATs in 54 (67%), fibrin monomers in 49 (60%), and D-dimer in 76 (94%). Statistically significant elevation in PF1.2 and TATs was seen in patients admitted to the ICU, while D-dimer and fibrin monomers were significantly elevated in patients with poor outcomes. The presence of multiple abnormal coagulation parameters was associated with ICU admission.
