ETHNOPHARMACOLOGICAL RELEVANCE Stryphnodendron adstringens has been used by indigenous Brazilian people to treat wound, infections, inflammation and other conditions. AIM OF THE STUDY This study aims to investigate the effect of S. adstringens on macrophage polarization. METHODS To prepare the hydroethanolic extract of Stryphnodendron adstringens (HESA), fresh bark was exposed to maceration, filtered and subsequently lyophilized. The extract HESA were analyzed by LC-DAD-MS to identify their constituents. Bone marrow cells were obtained from male C57BL/6 mice. Then, the cells were polarized into M1 or M2 subsets in the presence or absence of HESA. The membrane expression of TLR2, CD206, CCR7, class II MHC, and CD86, the intracellular expression of iNOS and IL-6 and the supernatant expression of IL-6 were determined by flow cytometry. RESULTS By LC-DAD-MS, twenty-four compounds could be detected from HESA and proanthocyanidins, flavan-3-ols, and chromones were identified. NO and iNOS were reduced in the HESA-treated cells. There was a reduction in IL6 in HESA-treated cells. The membrane expression of TLR2, CD206, CCR7, CD86, and class II MHC was reduced in HESA-treated cells. The densities of CD206 and IL-10 were found to be significantly increased in HESA-treated cells. CONCLUSION This work is the first to demonstrate that S. adstringens can modulate the functional polarization of macrophages into the M2 profile and suppress costimulatory molecules in M1 macrophages. These results corroborate with the ethnopharmacology use of S. adstringens, contributing to its pharmacological validation in wound treatment and expanding the knowledge about immunoregulatory action of this specie. ETHNOPHARMACOLOGICAL RELEVANCE Mercury sulfides (HgS) are frequently included in Ayurveda, Tibetan and Chinese medicines to assist the presumed therapeutic effects, but the ethnopharmacology remains elusive. The present study examined the protective effects of α-HgS-containing Hua-Feng-Dan and β-HgS-containing 70 Wei-Zhen-Zhu-Wan (70W, Rannasangpei) against Parkinson's disease mice induced by lipopolysaccharide (LPS) plus 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP). METHOD A single injection of LPS (5 mg/kg ip) was given to adult male C57BL/6 mice, and 150 days later, the low dose of MPTP (15 mg/kg, ip, for 4 days) was given to produce the "two-hit" Parkinson's disease model. Together with MPTP treatment, mice were fed with clinically-relevant doses of Hua-Feng-Dan (0.6 g/kg) and 70W (0.2 g/kg) for 35 days. Rotarod test was performed to examine muscle coordination capability. At the end of the experiment, brain was transcardially perfused with paraformaldehyde, the substantia nigra was sectioned for microglia (Iba1 staining) and dopaminergic neuron (THir staining) determination. Colon bacterial DNA was extracted and subjected to qPCR analysis with 16S rRNA probes. RESULTS The low-grade, chronic neuroinflammation produced by LPS aggravated MPTP neurotoxicity, as evidenced by decreased motor activity, intensified microglia activation and loss of dopaminergic neurons. Both Hua-Feng-Dan and 70W increased rotarod activity and ameliorated the pathological lesions in the brain. In gut microbiomes examined, LPS plus MPTP increased Verrucomicrobiaceae, Methanobacteriaceae, Pronicromonosporaceae, and Clostridaceae species were attenuated by Hua-Feng-Dan and 70W. CONCLUSIONS α-HgS-containing Hua-Feng-Dan and β-HgS-containing 70W at clinical doses protected against chronic LPS plus MPTP-induced toxicity to the brain and gut, suggesting HgS-containing traditional medicines could target gut microbiota as a mechanism of their therapeutic effects. PURPOSE Magnetic resonance (MR-)guided stereotactic ablative radiotherapy (SABR) was performed for patients with lung tumors in whom treatment delivery was challenging due to tumor location, motion or pulmonary comorbidity. As stereotactic MR-guided adaptive radiation therapy (or SMART) is a novel approach, we studied clinical outcomes in these high-risk lung tumors. METHODS AND MATERIALS Fifty consecutive patients (54 lung tumors) underwent SMART between 2016-2018 for either a primary lung cancer (29 patients), or for lung metastases (21 patients). Eligible patients had risk factors which could predispose to toxicity, including a central tumor location (n = 30), previous thoracic radiotherapy (n = 17), and interstitial lung disease (n = 7). A daily 17-second breath-hold MR scan was acquired in treatment position, and on-table plan adaptation was performed using the anatomy-of-the-day. Gated SABR was delivered during repeated breath-holds under continuous MR-guidance. RESULTS All but one patient completed the planned SMART schedule. With daily plan adaptation, a biologically effective dose (BED10Gy) ≥100Gy to 95% of the planning target volume was delivered in 50 tumors (93%). Median follow-up was 21.7 months (95%CI, 19.9-28.1). Local control, overall and disease-free survival rates at 12 months were 95.6%, 88.0% and 63.6%, respectively. Local failures developed in four patients two after re-irradiation for a recurrent lung cancer, and in two patients with a colorectal metastasis. Overall rates of any grade ≥2 and ≥3 toxicity were 30% and 8%, respectively. see more Commonest toxicities were grade ≥2 radiation pneumonitis (12%) and chest wall pain (8%). No grade 4-5 toxicities were observed. CONCLUSIONS Use of MR-guided SABR resulted in low rates of high-grade toxicity, and encouraging early local control, in a cohort of high-risk lung tumors. Additional studies are needed in order to identify patients who are most likely to benefit from the SMART approach. NMDA receptors (NMDARs) play a critical role in excitatory synaptic transmission, plasticity and in several forms of learning and memory. In addition, NMDAR dysfunction is believed to underlie a number of neuropsychiatric conditions. Growing evidence has demonstrated that NMDARs are tightly regulated by several G-protein-coupled receptors (GPCRs). Ligands that bind to GPCRs, such as neurotransmitters and neuromodulators, activate intracellular pathways that modulate NMDAR expression, subcellular localization and/or functional properties in a short- or a long-term manner across many synapses throughout the central nervous system. In this review article we summarize current knowledge on the molecular and cellular mechanisms underlying NMDAR modulation by GPCRs, and we discuss the implications of this modulation spanning from synaptic transmission and plasticity to circuit function and brain disease. Electric current has been used for epilepsy treatment by targeting specific neural circuitries. Despite its success, direct contact between the electrode and tissue could cause side effects including pain, inflammation, and adverse biological reactions. Magnetic stimulation overcomes these limitations by offering advantages over biocompatibility and operational feasibility. However, the underlying neurological mechanisms of its action are largely unknown. In this work, a magnetic generating system was assembled that included a miniature coil. The coil was positioned above the CA3 area of mouse hippocampal slices. Epileptiform activity (EFA) was induced with low Mg2+/high K+ perfusion or with 100 µM 4-aminopyridine (4-AP). The miniature coil generated a sizable electric field that suppressed the local EFA in the hippocampus in the low-Mg2+/high-K+ model. The inhibition effect was dependent on the frequency and duration of the magnetic stimulus, with high frequency being more effective in suppressing EFA. EFA suppression by the magnetic field was also observed in the 4-AP model, in a frequency and duration - dependent manner. The study provides a platform for further investigation of cellular and molecular mechanisms underlying epilepsy treatment with time varying magnetic fields. New lanthanide complexes (1-3) of the general formulae [Ln(L)(NO3)(H2O)] have been synthesized by reaction of Ln(NO3)3.xH2O Ln = La (1), Sm (2) and Yb (3) with 2,2'-(((1E,1'E)-thiophene-2,5-diylbis(methaneylylidene))bis(azaneylylidene))diphenol (H2L). Based on elemental analysis and spectroscopic analysis (UV-Visible, FT-IR, ESI-MS 1H and 13C NMR), molar conductance and thermogravimetric analysis. The results showed that the Schiff base ligand coordinated Ln(III) ions through the azomethine nitrogens, deprotonated hydroxyl groups, and thiophene sulphur atom. The interaction of the synthetic compounds with CT-DNA has been studied to investigate their anticancer activitiy by the electronic spectroscopy, fluorometric competition studies with ethidium bromide and DNA viscosity measurements. Furthermore, due to the ligand and its Ln(III) complexes exhibit good DNA binding affinity, it is considered worthwhile to investigate their antioxidant activity. The data have shown that, the complexes are more effective inhibitors towards reactive oxygen species (ROS), such as superoxide anion and hydroxyl radical. The activity of test compounds in ascending order (1) > (2) > (3) > H2L in terms of IC50 value. The anticancer activities of the complexes have also been studied towards human colon carcinoma cancer (HCT-116) and human breast cancer (MCF-7) cell lines. The aim of this study is to establish a method for rapid screening of active ingredients targeting TNF-α from Chinese herbal medicines. Take Angelicae Pubescentis Radix (APR) as an example, surface plasma resonance technique was used to establish for screening small molecule inhibitors of TNF-α from APR extract. Then UPLC-MS/MS coupled with chemometric was used for quantitative and evaluate the differences of the candidate compounds bound to TNF-α in APR from different sources. In the experiment, TNF-α protein was fixed on the CM5 chip surface of biacore T200 biosensor by amino coupling. A series of small molecular compounds in APR were screened and six phenolic acid compounds had a strong affinity for TNF-α protein and could be used as TNF-α antagonists. In summary, the targeted drug screening method for TNF-α protein based on SPR technology established in this study can be used to screen anti-TNF-α small molecule inhibitors. UPLC-MS/MS can accurately quantify 15 active ingredients, which provides reliable experimental data and new research ideas for targeted drug research on TNF-α protein. Flavonoids interfere with colorimetric protein assays in a concentration- and structure-dependent manner. Degree (≥3) and position (C3) of -OH substitution was associated with intensified interference (p 5 μM) and is particularly evident at lower protein concentrations (25-250 μg/ml). Since, healthy human urinary protein ( less then 200 μg/ml) and flavonoids urinary excretion (0.5-2 μg/ml) levels fall in this range, overestimation of protein concentration with flavonoids consumption in diet, including natural supplements, remains relevant issue for diagnostic and research labs. Protein precipitation by acetone to remove interfering flavonoid successfully resolves the problem. Membrane proteins are generally challenging to work with because of their notorious instability. Protein engineering has been used increasingly to thermostabilize labile membrane proteins such as G-protein coupled receptors for structural and functional studies in recent years. Two major strategies exist. Scanning mutagenesis systematically eliminates destabilizing residues, whereas the consensus approach assembles mutants with the most frequent residues among selected homologs, bridging sequence conservation with stability. Here we applied the consensus concept to stabilize a fungal homolog of the human sterol Δ8-7 isomerase, a 26.4-kDa protein with five transmembrane helices. The isomerase is also called emopamil binding protein (EBP) as it binds this anti-ischemic drug with high affinity. The wild-type had an apparent melting temperature (Tm) of 35.9 °C as measured by the fluorescence-detection size-exclusion chromatography (FSEC)-based thermostability assay. A total of 87 consensus mutations sourced from 22 homologs gained expression level and thermostability, increasing the apparent Tm to 69.
