#Nanoparticle-Mediated Delivery of 2-Deoxy-D-Glucose Induces Antitumor Immunity and Cytotoxicity in #Liver Tumors in Mice

Immune checkpoint inhibitors have shed light on the importance of antitumor immunity as a therapeutic strategy for hepatocellular carcinoma (HCC). The altered glucose metabolism known as the Warburg effect recently has gained attention as a cancer immune-resistance mechanism. Considering glycolysis inhibitors as therapeutic agents, their specific delivery to cancer cells is critical not to induce adverse effects. Thus, we investigated antitumor effects of a glycolysis … Continue reading #Nanoparticle-Mediated Delivery of 2-Deoxy-D-Glucose Induces Antitumor Immunity and Cytotoxicity in #Liver Tumors in Mice

#Plasma tissue plasminogen activator and plasminogen activator inhibitor-1 in hospitalized #COVID-19 patients

Patients with coronavirus disease-19 (COVID-19) are at high risk for thrombotic arterial and venous occlusions. However, bleeding complications have also been observed in some patients. Understanding the balance between coagulation and fibrinolysis will help inform optimal approaches to thrombosis prophylaxis and potential utility of fibrinolytic-targeted therapies. 118 hospitalized COVID-19 patients and 30 healthy controls were included in the study. We measured plasma antigen levels of … Continue reading #Plasma tissue plasminogen activator and plasminogen activator inhibitor-1 in hospitalized #COVID-19 patients

The Efficacy and Safety of Vitamin #C for Iron Supplementation in Adult Patients With Iron Deficiency #Anemia

It remains uncertain whether vitamin C routinely used with oral iron supplements is essential for patients with iron deficiency anemia (IDA).. ..The primary outcome was the change in hemoglobin level from baseline to 2 weeks of treatment, and an equivalence margin of 1 g/dL in hemoglobin was chosen for the demonstration of comparable efficacy. Secondary outcomes included the change in the reticulocyte percentage after 2 … Continue reading The Efficacy and Safety of Vitamin #C for Iron Supplementation in Adult Patients With Iron Deficiency #Anemia

American Society of Hematology 2020 guidelines for management of venous #thromboembolism: treatment of deep vein #thrombosis and pulmonary #embolism

Venous thromboembolism (VTE), which includes deep vein thrombosis (DVT) and pulmonary embolism (PE), occurs in ∼1 to 2 individuals per 1000 each year, corresponding to ∼300 000 to 600 000 events in the United States annually.. ..Strong recommendations include the use of thrombolytic therapy for patients with PE and hemodynamic compromise, use of an international normalized ratio (INR) range of 2.0 to 3.0 over a lower INR … Continue reading American Society of Hematology 2020 guidelines for management of venous #thromboembolism: treatment of deep vein #thrombosis and pulmonary #embolism

Transcriptomic and clonal characterization of #T cells in the human central #nervous system

T cells provide critical immune surveillance to the central nervous system (CNS), and the cerebrospinal fluid (CSF) is thought to be a main route for their entry. Further characterization of the state of T cells in the CSF in healthy individuals is important for understanding how T cells provide protective immune surveillance without damaging the delicate environment of the CNS and providing tissue-specific context for … Continue reading Transcriptomic and clonal characterization of #T cells in the human central #nervous system

Relationship between the ABO #Blood Group and the #COVID-19 Susceptibility

Detection of ABO blood groups, infection occurrence of SARS-CoV-2, and patient death RESULTS The ABO group in 3694 normal people in Wuhan showed a distribution of 32.16%, 24.90%, 9.10% and 33.84% for A, B, AB and O, respectively, versus the distribution of 37.75%, 26.42%, 10.03% and 25.80% for A, B, AB and O, respectively, in 1775 COVID-19 patients from Wuhan Jinyintan Hospital. The proportion of … Continue reading Relationship between the ABO #Blood Group and the #COVID-19 Susceptibility

Red #blood cell dysfunction: a new player in #cardiovascular disease

The primary role of red blood cells (RBCs) is to transport oxygen to the tissues and carbon dioxide to the lungs. However, emerging evidence suggests an important role of the RBC beyond being just a passive carrier of the respiratory gases. The RBCs are of importance for redox balance and are actively involved in the regulation of vascular tone, especially during hypoxic and ischaemic conditions … Continue reading Red #blood cell dysfunction: a new player in #cardiovascular disease

Vitamin #B6 Addiction in Acute Myeloid #Leukemia

Cancer cells rely on altered metabolism to support abnormal proliferation. We performed a CRISPR/Cas9 functional genomic screen targeting metabolic enzymes and identified PDXK—an enzyme that produces pyridoxal phosphate (PLP) from vitamin B6—as an acute myeloid leukemia (AML)-selective dependency.. PDXK kinase activity is required for PLP production and AML cell proliferation, and pharmacological blockade of the vitamin B6 pathway at both PDXK and PLP levels recapitulated … Continue reading Vitamin #B6 Addiction in Acute Myeloid #Leukemia
