The aim of this study was to apply a new instrumental approach to the analysis of human bone marrow for forensic purposes. A new screening method for the detection of more than 30 psychoactive drugs in bone marrow was developed and applied to case samples. The drugs used in this study belonged to the following groups: benzodiazepines (BZDs, n=16), tricyclic antidepressants (TCAs, n=5), selective serotonin reuptake inhibitors (SSRI, n=4), serotonin-norepinephrine reuptake inhibitors (n=1), anticonvulsants (n=1), imidazopyridines (n=1) and piperazines (n=3). The sample preparation procedure involved microwave-assisted extraction (MAE) and the experimental settings were optimized using the simplex method. Separation and detection was carried out using a UHPLC-TOF system. The method were validated using marrow samples, and further applied in the analysis of three case samples, in which diazepam, nordiazepam, citalopram, doxepin and paroxetine were successfully detected. Finally the presented method is a good example of an assay that could potentially find an application in forensic analysis.

Anemia is a common consequence of myelofibrosis. The treatment of myelofibrosis-associated anemia is complicated by a multifactorial pathobiology, as well as a lack of therapies that result in normalization of the bone marrow and complete restoration of its function. Established agents that are used to treat anemia in other bone marrow failure states such as myelodysplastic syndromes and aplastic anemia, are used for the treatment of myelofibrosis-associated anemia.

The biology centered around the TGF-beta type I receptor Activin Receptor-Like Kinase (ALK)1 (encoded by ACVRL1) has been almost exclusively based on its reported endothelial expression pattern since its first functional characterization more than two decades ago. Here, in efforts to better define the therapeutic context in which to use ALK1 inhibitors, we uncover a population of tumor-associated macrophages (TAMs) that, by virtue of their unanticipated Acvrl1 expression, are effector targets for adjuvant anti-angiogenic immunotherapy in mouse models of metastatic breast cancer. The combinatorial benefit depended on ALK1-mediated modulation of the differentiation potential of bone marrow-derived granulocyte-macrophage progenitors, the release of CD14+ monocytes into circulation, and their eventual extravasation.

B-cell acute lymphoblastic leukemia (B-ALL) is the most common form of cancer diagnosed in children. While the majority of patients survive with conventional treatment, chemotherapeutic agents have adverse effects and the potential for relapse persists even after full recovery. Given their pivotal function in anti-cancer immunity, there has been a surge in research exploring the potential of natural killer (NK) cells in immunotherapy, which has emerged as a promising avenue for treating leukemia.

Purpose: Despite advances in the treatment of adult acute lymphoblastic leukemia (ALL), relapse remains the most significant challenge in improving prognosis. Measurable residual disease (MRD) assessment can predict bone marrow relapse based on MRD positivity. As access to innovative therapies remains limited because of the high cost, chemotherapy is the widely utilized treatment option.
