Association between JAK2 variable allele frequency and risk of thrombotic events in patients with myeloproliferative neoplasms.

Background: Myeloproliferative neoplasms (MPNs) are a group of chronic disorders of the bone marrow characterised by the overproduction of clonal myeloid stem cells. The most common driver mutation found in MPNs is a point mutation on exon 14 of the JAK2 gene, JAK2. Various studies have suggested that measuring the variable allele frequency (VAF) of JAK2 may provide useful insight regarding diagnosis, treatment, risks and outcomes in MPN patients.

Low-Platinum-Content Exchange-Coupled CoPt Nanoalloys with Enhanced Magnetic Properties.

Bimetallic colloidal CoPt nanoalloys with low platinum content were successfully synthesized following a modified polyol approach. Powder X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA), and transmission electron microscopy (TEM) studies were performed to estimate the crystal structure, morphology, and surface functionalization of the colloids, respectively, while the room-temperature magnetic properties were measured using a vibrating sample magnetometer (VSM). The particles exhibit excellent uniformity, with a narrow size distribution, and display strong room-temperature hysteretic ferromagnetic behavior even in the as-made form.

Application of glutamate weighted CEST in brain imaging of nicotine dependent participants in vivo at 7T.

Introduction: With nicotine dependence being a significant healthcare issue worldwide there is a growing interest in developing novel therapies and diagnostic aids to assist in treating nicotine addiction. Glutamate (Glu) plays an important role in cognitive function regulation in a wide range of conditions including traumatic brain injury, aging, and addiction. Chemical exchange saturation transfer (CEST) imaging via ultra-high field MRI can image the exchange of certain saturated labile protons with the surrounding bulk water pool, making the technique a novel tool to investigate glutamate in the context of addiction.

Disclosure and Help-Seeking Experiences of Sexual and Gender Minority Victims of Intimate Partner Violence: A Mixed-Methods Study.

Sexual and gender minorities assigned female at birth (SGM-AFAB) experience high rates of intimate partner violence (IPV), with negative effects on health and well-being. Disclosure of and help-seeking for IPV can support the well-being of IPV survivors, yet are understudied among SGM-AFAB people. To better understand the IPV disclosure and help-seeking experiences in this population, we conducted semi-structured interviews with 41 SGM-AFAB young adults who experienced physical, sexual, or severe psychological IPV.
