Xiuwen Chen, He Zhao, Chunlian Chen, Huanfeng Jiang, Min Zhang
By a hydrogen transfer-mediated activation mode for non-activated pyridyl nucleus, a general catalytic hydrogen transfer-mediated -functionalization of 1,8-naphthyridines is reported for the first time. Its -site selectively couples with the C8-site of various tetrahydroquinolines (THQs) to afford novel -functionalized tetrahydro 1,8-naphthyridines, a class of synthetically useful building blocks and potential candidates for the discovery of therapeutic and bio-active products. The utilization of THQs as inactive hydrogen donors (HDs) appears to be a key strategy to overcome the over-hydrogenation barrier and address the chemo-selectivity issue...

BACKGROUND: Common variable immunodeficiency (CVID) is a heterogeneous immune deficiency characterized by hypogammaglobulinemia. Since B cell maturation and differentiation is defective in this disorder, we evaluated apoptosis in B cells of patients with CVID compared with healthy donors (HD). METHODS: Determination of peripheral blood B-cell subsets in CVID and HDs, was performed using flow cytometry. We compared total apoptosis, early apoptosis and late apoptosis/necrosis in unstimulated and stimulated B-cells of patients with CVID and HDs...

Idiosyncratic drug-induced liver injury (DILI) and hepatic injury due to herbal and dietary supplements (HDS) can adapt clinical characteristics of autoimmune hepatitis (AIH), such as the appearance of autoantibodies and infiltration of the liver by immune competent cells. To describe these cases of DILI/HDS, the poorly-defined term "autoimmune(-like)" DILI/HDS came up. It is uncertain if these cases represent a subgroup of DILI/HDS with distinct pathomechanistic and prognostic features different from "classical" DILI/HDS...

Microvesicles (MVs) are released by immune cells especially of the myeloid lineage upon stimulation with ATP on its cognate receptor P2X7, both in physiological and pathological conditions. In multiple sclerosis (MS) the role of MVs remains little investigated. We aimed to compare the release of MVs in peripheral blood monocytes from MS patients with healthy donors (HDs) and to see how current MS treatment may affect such a production. We also assessed the treatment effect on M1 and M2 monocyte polarization and on the inflammasome components...

Optical control of magnetization using femtosecond laser without applying any external magnetic field offers the advantage of switching magnetic states at ultrashort time scales. Recently, all-optical helicity-dependent switching (AO-HDS) has drawn a significant attention for potential information and data storage device applications. In this work, we employ element and magnetization sensitive photoemission electron microscopy (PEEM) to investigate the role of heating in AO-HDS for thin films of the rare-earth transition-metal alloy TbFe...

VSe<sub>2</sub> is a typical layered semimetal among TMDCs and thought to be hard to be synthesized for many years. By changing the concentration of precursors and reaction steps in hydrothermal method, here we successfully synthesize VSe2 of three different shapes: nano-hydrangea (NH), nano-dandelion (ND) and hexagonal disk (HD). The as-prepared VSe2 HDs are of single-crystalline structure compared with the poly-crystalline structure of NHs and NDs. The as-prepared VSe2 of these three shapes also shows apparent differences and intrinsic properties both in the nitrogen adsorption-desorption characterizations and UV-vis absorption analysis...

The role of autoimmune mechanisms in idiopathic small fiber neuropathy (SFN) is not completely understood. Serum IgM binding to trisulfated disaccharide IdoA2S-GlcNS-6S (TS-HDS) and IgG to fibroblast growth factor receptor 3 were associated with sensory motor polyneuropathies and sensory neuronopathy among others. In this retrospective case review, we describe the clinical and laboratory findings of idiopathic SFN in a small cohort of pediatric patients. Eight children were diagnosed with SFN clinically and confirmed by reduced epidermal nerve fiber density...

Long-term therapy with doxorubicin (DOX) is associated with high incidence of cumulative and irreversible dilated cardiomyopathy. The goal of this study was to evaluate the cardioprotective effects and safety of a phlorotannin extract from a brown algae Ecklonia cava (Seapolynol™, SPN) against DOX-induced cardiotoxicity in a rat model. A total of 42 rats were divided into six groups: control, low-dose SPN (LDS), high-dose SPN (HDS), DOX, DOX with low-dose SPN (DOX+LDS), and DOX with high-dose SPN (DOX+HDS)...

The effect of 2,6-bis-(1-hydroxy-1,1-diphenyl-methyl) pyridine (BDPHP) in the preparation of NiMoP/γ-Al₂O₃ catalysts have been investigated in the hydrodesulfurization (HDS) of straight-run gas oil. The γ-Al₂O₃ support was modified by surface impregnation of a solution of BDPHP to afford BDPHP/Ni molar ratios (0.5 and 1.0) in the final composition. The highest activity for NiMoP materials was found when the molar ratio of BDPHP/Ni was of 0.5. X-ray diffraction (XRD) results revealed that NiMoP (0...

Acute liver failure (ALF) requires urgent attention to identify etiology and determine prognosis, in order to assess likelihood of survival or need for transplantation. Identifying idiosyncratic drug-induced liver injury (iDILI) may be particularly difficult, but the illness generally follows a subacute course, allowing time to assess outcome and find a liver graft if needed. Not all drugs that cause iDILI lead to ALF; the most common are antibiotics including anti-tuberculous medications, non-steroidal anti-inflammatory agents and herbal and dietary supplements (HDS)...

A 3D highly interconnected macroporous network of reduced GO having finely dispersed few-layered 2D MoS2 nanosheets was constructed through direct use of acidic graphite oxide (GO) for the first time. This facile and technological scalable process can afford an efficient electrocatalysts, anode materials, HDS catalysts at lower cost and can circumvent the poor thermal stability and recyclability of the material. The strategy provided here can be the basis to design and develop practical processes to address the ultimate goal of large-scale manufacturing of hybrids composed of 2D materials for various energy and catalysis applications...

BACKGROUND: Myelofibrosis (MF) is the most aggressive Philadelphia-negative chronic myeloproliferative neoplasm (MPN) with high morbidity and mortality due to thrombo-hemorrhagic complications and leukemic transformation. MF is characterized by profound alterations of megakaryocytopoiesis, with consequent abnormalities in platelet number and function. We recently showed that the overexpression of the oncoprotein PKCepsilon plays a key role in the aberrant differentiation of MF megakaryocyte clone and that its levels correlate with disease burden...

Petroleum industries continuously consume catalysts on very large scales. The recycling of spent catalysts is thus of major economic and environmental importance and its first step consists of the characterization of the valuable metal content. Wavelength dispersive X-ray fluorescence (WDXRF) analysis is compared with inductively coupled plasma atomic emission spectrometry (ICP-AES) for the analysis of five samples of spent hydrodesulphurization (HDS) and hydrodemetallization (HDM) catalysts. The elements are considered for their economic interest (Co, Ni, Mo, and V) or for the problems that can arise when they are present in the sample in significant quantities (Al, As, P, Fe)...

BACKGROUND: In health, inflammation resolution is an active process governed by specialized proresolving mediators and receptors. ALX/FPR2 receptors (ALX) are targeted by both proresolving and proinflammatory ligands for opposing signaling events, suggesting pivotal roles for ALX in the fate of inflammatory responses. Here, we determined if ALX expression and ligands were linked to severe asthma (SA). METHODS: ALX expression and levels of proresolving ligands (lipoxin A4 [LXA4], 15-epi-LXA4, and annexin A1 [ANXA1]), and a proinflammatory ligand (serum amyloid A [SAA]) were measured in bronchoscopy samples collected in Severe Asthma Research Program-3 (SA [n = 69], non-SA [NSA, n = 51] or healthy donors [HDs, n = 47])...
