Use of haploidentical (haplo) donors for hematopoietic cell transplantation (HCT) has significantly increased in the last decade. The major advantage with this strategy is universal availability and faster acquisition of the donor, along with affordability and provision of immunotherapy in post-transplantation period. Historically, haplo-HCT was associated with compromised outcomes because of high rates of graft-versus-host disease and graft failure, but after the development of a post-transplantation high-dose cyclophosphamide strategy, which results in selective T-cell depletion, these issues have been addressed to a large extent.

Objective: The purpose of this laboratory study was to evaluate the fatigue resistance, fracture resistance and mode of failure of posterior hybrid-abutment-crown versus hybrid-abutment with separate crown, both bonded to short titanium bases.
Materials And Methods: Thirty-two titanium implants were embedded perpendicularly in auto-polymerizing resin. Implant-supported restorations simulating a maxillary first premolar were designed and milled using a CAD/CAM system and divided into 2 groups according to material (n=16): zirconia (Z) and lithium disilicate (L).

Motivation: Histones form octameric complexes called nucleosomes, which organize the genomic DNA of eukaryotes into chromatin. Each nucleosome comprises two copies each of the histones H2A, H2B, H3, and H4, which share a common ancestry. Although histones were initially thought to be a eukaryotic innovation, the subsequent identification of archaeal homologs led to the notion that histones emerged before the divergence of archaea and eukaryotes.

Hemagglutinin (HA) stalk-reactive antibodies are the basis of several current "one-shot" universal influenza vaccine efforts because they protect against a wide spectrum of influenza virus strains. The appreciated mechanism of protection by HA-stalk antibodies is to inhibit HA stalk reconfiguration, blocking viral fusion and entry. This study shows that HA stalk-reactive antibodies also inhibit neuraminidase (NA) enzymatic activity, prohibiting viral egress. Read More

Background And Aim: The majority of seasonal influenza vaccines are trivalent, containing two A virus strains (H1N1 and H3N2) and one B virus strain. The co-circulation of two distinct lineages of B viruses can lead to mismatch between the influenza B virus strain recommended for the trivalent seasonal vaccine and the circulating B virus. This has led some manufacturers to produce quadrivalent influenza vaccines containing one strain from each B lineage in addition to H1N1 and H3N2 strains. Read More

We investigate spatiotemporal dynamics of human interphase chromosomes by employing a heteropolymer model that incorporates the information of human chromosomes inferred from Hi-C data. Despite considerable heterogeneities in the chromosome structures generated from our model, chromatins are organized into crumpled globules with space-filling (SF) statistics characterized by a single universal scaling exponent (ν = 1/3), and this exponent alone can offer a quantitative account of experimentally observed, many different features of chromosome dynamics. The local chromosome structures, whose scale corresponds to that of topologically associated domains (∼ 0. Read More

Purpose Of Review: Genitoplasty in children with disorders of sex development (DSD) is an ethically complex issue. From a surgical perspective, genitoplasty in early childhood is preferred because it is felt to be associated with improved tissue healing, decreased risk of complications, and reduced psychological impact of genital surgery. However, advocacy groups and recent ethics literature have argued for deferring genitoplasty until a child reaches decisional maturity. Read More

Medical devices are indispensable for cancer management across the entire cancer care continuum, yet many existing medical interventions are not equally accessible to the global population, contributing to disparate mortality rates between countries with different income levels. Improved access to priority medical technologies is required to implement universal health coverage and deliver high-quality cancer care. However, the selection of appropriate medical devices at all income and hospital levels has been difficult because of the extremely large number of devices needed for the full spectrum of cancer care; the wide variety of options within the medical device sector, ranging from small inexpensive disposable devices to sophisticated diagnostic imaging and treatment units; and insufficient in-country expertise, in many countries, to prioritise cancer interventions and to determine associated technologies.

Replication dependent (RD) core histone mRNA produced during S-phase is the only known protein-coding mRNA presenting a 3' stem-loop instead of the otherwise universal polyA tail. A metallo β-lactamase (MBL) fold enzyme, cleavage and polyadenylation specificity factor 73 (CPSF73), is proposed to be the sole endonuclease responsible for 3' end processing of both mRNA classes. We report cellular, genetic, biochemical, substrate selectivity, and crystallographic studies providing evidence that an additional endoribonuclease, MBL domain containing protein 1 (MBLAC1), is selective for 3' processing of RD histone pre-mRNA during the S-phase of the cell cycle.

The use of different biomaterials with the ability to accelerate the repair and regeneration processes is of great importance in tissue engineering strategies. On this point, cerium oxide nanoparticles (CNPs or nanoceria) have recently attracted much attention due to their excellent biological properties including anti-oxidant, anti-inflammation and antibacterial activities as well as high angiogenic potential. The results of incorporation of these nano-sized particles into various constructs and scaffolds designed for tissue engineering applications have proven the success of this strategy in terms of improving healing process of different tissues.

Integration of biological macromolecules with inorganic materials via biomineralization has demonstrated great potential for development of nanotheranostic agents. To produce multifunctionality, integration of multiple components in the biomineralized theranostic agents is required; however, how to efficiently and reproducibly implement this is challenging. In this report, a universal biomineralization strategy is developed by incorporation of oxidization polymerization into albumin-templated biomineralization for facile synthesis of nanotheranostic agents.

Objectives: The aim of the study was to assess whether the timing of combination antiretroviral therapy (cART) initiation, the choice of cART and virological response differ in migrants versus European natives in the north and east of Paris area, after dissemination of French recommendations for universal treatment.
Methods: Antiretroviral therapy-naïve HIV-1-infected adults with at least two follow-up visits at one of 15 participating centres between 1 January 2014 and 31 March 2015 were included in the study.

Preimplantation genetic testing has evolved tremendously from the early days of FISH detection for a select few chromosome aneuploidies to now combining the detection of all whole chromosome imbalances in conjunction with single gene disorder testing for inherited diseases. As universal carrier screening and exome or genome studies become more commonplace, more and more families are becoming interested in reducing the risk of having a child with a severe disease using preimplantation genetic testing. We describe here the use of quantitative PCR (qPCR) for the custom construction of single gene disorder testing plans for families, the validation of the probes designed, and the protocol for diagnosing an embryo biopsy.
