Mahmood, Armed Forces Bone Marrow Transplant Centre/National Institute of Blood and Marrow Transplant, Rawalpindi; Parvez Ahmed, Quaid-e-Azam International Hospital, Islamabad, Pakistan; and Qaiser Bashir, MD Anderson Cancer Centre, Houston, TX.

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.

Histones Predate the Split Between Bacteria and Archaea.

Bioinformatics 2018 Dec 6. Epub 2018 Dec 6.

Department of Protein Evolution, Max Planck Institute for Developmental Biology, Tübingen, Germany.

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 stalk-reactive antibodies interfere with influenza virus neuraminidase activity by steric hindrance.

J Virol 2018 Dec 5. Epub 2018 Dec 5.

Department of Medicine, Section of Rheumatology, the Knapp Center for Lupus and Immunology, University of Chicago, Chicago, IL 60637, USA.

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

Rationale for vaccination with trivalent or quadrivalent live attenuated influenza vaccines: Protective vaccine efficacy in the ferret model.

PLoS One 2018 3;13(12):e0208028. Epub 2018 Dec 3.

International Institutional Cooperation, Institut national de la santé et de la recherche médicale (INSERM), Paris, France.

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

Chain organization of human interphase chromosome determines the spatiotemporal dynamics of chromatin loci.

PLoS Comput Biol 2018 Dec 3;14(12):e1006617. Epub 2018 Dec 3.

Korea Institute for Advanced Study, Seoul, Korea.

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

Defining priority medical devices for cancer management: a WHO initiative.

Lancet Oncol 2018 Dec;19(12):e709-e719

Abramson Cancer Center, University of Pennsylvania, Philadelphia, Pennsylvania, PA, USA.

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.

Biosynthesis of histone messenger RNA employs a specific 3' end endonuclease.

Elife 2018 Dec 3;7. Epub 2018 Dec 3.

Department of Chemistry, University of Oxford, Oxford, United Kingdom.

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.

Molecular Testing for Preimplantation Genetic Diagnosis of Single Gene Disorders.

Methods Mol Biol 2019 ;1885:61-71

Thomas Jefferson University, Basking Ridge, NJ, USA.

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.

Histidine kinases (HKs) funnel diverse environmental stimuli into a single autophosphorylation event at a conserved histidine residue. The HK EnvZ is a global sensor of osmolality and cellular acid pH. In previous studies, we discovered that osmosensing in EnvZ was mediated through osmolyte-induced stabilization of the partially disordered helical backbone spanning the conserved histidine autophosphorylation site (His).

Cognitive markers of preclinical and prodromal Alzheimer's disease in Down syndrome.

Alzheimers Dement 2018 Nov 15. Epub 2018 Nov 15.

Department of Forensic and Neurodevelopmental Sciences, Institute of Psychiatry, Psychology and Neuroscience, King's College London, London, UK; Division of Psychiatry, University College London, London, UK; The LonDownS Consortium, London, UK.

Introduction: Down syndrome (DS) is associated with an almost universal development of Alzheimer's disease. Individuals with DS are therefore an important population for randomized controlled trials to prevent or delay cognitive decline, though it is essential to understand the time course of early cognitive changes.

Methods: We conducted the largest cognitive study to date with 312 adults with DS to assess age-related and Alzheimer's disease-related cognitive changes during progression from preclinical to prodromal dementia, and prodromal to clinical dementia. Read More

A versatile strategy to create active tumor-targeted chemo-photothermal therapy nanoplatform: a case of IR-780 derivative co-assembled with camptothecin prodrug.

Acta Biomater 2018 Nov 29. Epub 2018 Nov 29.

School of Pharmaceutical Science, Key Laboratory of Chemical Biology (Ministry of Education), Shandong University, 44 West Wenhua Road, Jinan, Shandong Province 250012, PR China. Electronic address:

Self-assembled nanovehicles of chemotherapy drug with photothermal agent are regarded as intriguing chemo-photothermal therapy nanoplatform. However, most of the drugs and photothermal agents have poor water solubility and poor interactions to drive the formation of self-assembled nanovehicles, which is a bottleneck of co-assembled drug/photothermal agent for cancer therapy. Here, we proposed a versatile strategy to create self-assembled chemo-photothermal therapy nanoplatform based on the chemical modification of photothermal agent and drug. Read More
