We report development, automation and validation of 3D, microfluidic liver-on-a-chip for high throughput hepatotoxicity screening, OrganoPlate LiverTox. The model is comprised of aggregates of induced pluripotent stem cell-derived hepatocytes seeded in an extracellular matrix in organ channel and co-cultured with endothelial cells and THP-1 monoblasts differentiated to macrophages seeded in vascular channel of the 96 well Mimetas OrganoPlate 2-lane. A combination of secretome measurements and image-based anal. was used to demonstrate stable 15 day cell viability, albumin and urea secretion. Over same time-period, CYP3A4 activity increased and alpha-fetoprotein secretion decreased suggesting further maturation of iHeps. Troglitazone, clin. hepatotoxin, was chosen as control compound for validation studies. Albumin, urea, hepatocyte nuclear size and viability staining provided Robust Z’factors > 0.2 in plates treated 72 h with 180μM troglitazone compared with vehicle control. The viability assay provided the most robust statistic for a Robust Z’ factor = 0.6. A small library of 159 compounds with known liver effects was added to OrganoPlate LiverTox model for 72 h at 50μM and Toxicol. Prioritization scores were calculated A follow up dose-response evaluation of select hits revealed albumin assay to be most sensitive in calculating TC50 values. This platform provides a robust, novel model which can be used for high throughput hepatotoxicity screening. This study involved multiple reactions and reactants, such as 2-(4-(1-Hydroxy-4-(4-(hydroxydiphenylmethyl)piperidin-1-yl)butyl)phenyl)-2-methylpropanoic acid (cas: 83799-24-0Quality Control of 2-(4-(1-Hydroxy-4-(4-(hydroxydiphenylmethyl)piperidin-1-yl)butyl)phenyl)-2-methylpropanoic acid).

Several caspases have been implicated in the pathogenesis of Huntington’s disease (HD); however, existing caspase inhibitors lack the selectivity required to investigate the specific involvement of individual caspases in the neuronal cell death associated with HD. In order to explore the potential role played by caspase-2, the potent but non-selective canonical Ac-VDVAD-CHO caspase-2 inhibitor 1 was rationally modified at the P₂ residue in an attempt to decrease its activity against caspase-3. With the aid of structural information on the caspase-2, and -3 active sites and mol. modeling, a 3-(S)-substituted-L-proline along with four addnl. scaffold variants were selected as P₂ elements for their predicted ability to clash sterically with a residue of the caspase-3 S₂ pocket. These elements were then incorporated by solid-phase synthesis into pentapeptide aldehydes 33a–v. Proline-based compound 33h bearing a bulky 3-(S)-substituent displayed advantageous characteristics in biochem. and cellular assays with 20- to 60-fold increased selectivity for caspase-2 and ∼200-fold decreased caspase-3 potency compared to the reference inhibitor 1.

Vasodilator effect of 1-trifluoromethoxyphenyl-3-(1- propionylpiperidin-4-yl) urea is predominantly mediated through activation of voltage-dependent K+ channels was written by Shah, Shafiq Ali;Mehmood, Malik Hassan;Khan, Munasib;Bukhari, Ishfaq Ali;Gilani, Anwarul Hassan. And the article was included in Tropical Journal of Pharmaceutical Research in 2018.Recommanded Product: 1-(1-Propionylpiperidin-4-yl)-3-(4-(trifluoromethoxy)phenyl)urea The following contents are mentioned in the article:

To determine the mechanism of vasorelaxant effect of 1-trifluoromethoxyphenyl-3-(1-propionylpiperidin-4-yl) urea in cardiovascular diseases, including hypertension. Isolated rat thoracic aortic tissue preparations were mounted in an organ bath set up integrated with isometric transducer and a Power Lab assembly. TPPU was tested for vasorelaxant effect against low K⁺ (25 mM) and high K⁺ (80 mM)-induced contractions and its mechanism was determined in the presence of different antagonists (glibenclamide, 4- aminopyridine and tetra-Et ammonium). In rat aortic preparations, TPPU showed a concentration-dependent (0.3 – 100μM) and significant (p < 0.001) inhibition of low K⁺ induced contractions with complete inhibition obtained at 100μM. TPPU produced significant inhibition of high K⁺ induced contractions with maximum relaxation of 15.36 ± 1.95% and 15.85 ± 3.35% at 30 and 100μM, resp. Glibenclamide (Gb,10μM) pretreatment partially inhibited the vasorelaxant effect of TPPU against low K⁺ in a concentration range of 1 – 30μM. 4-Aminopyridine (4-AP, 1 mM) and tetra-Et ammonium markedly inhibited the vasorelexant effect of TPPU against low K⁺ induced contractions with maximum relaxation of 20.09 ± 2.40 and 21.67 ± 0.88%, resp., at 100μM. TPPU possesses marked vasorelaxant properties which provides sound pharmacol. evidence for its use as a potential drug candidate in the management of hypertension.

Pencil graphite electrode modified with nitrogen-doped graphene and molecular imprinted polyacrylamide/sol-gel as an ultrasensitive electrochemical sensor for the determination of fexofenadine in biological media was written by Oghli, Abbas Hassan;Soleymanpour, Ahmad. And the article was included in Biochemical Engineering Journal in 2021.Recommanded Product: 83799-24-0 The following contents are mentioned in the article:

A sensitive and selective sensor was developed for the determination of fexofenadine (FEX) drug. The sensor was constructed based on the modification of a pencil graphite electrode (PGE) as a low cost, high available and versatile working electrode. The PGE was modified by nitrogen-doped graphene (NDG) and molecularly imprinted polymer (MIP) as receptor to increase the sensitivity and reducing the interference of other chems. NDG was electrochem. deposited on the electrode surface which is more homogeneous and facilitated than its conventional chem. synthesis. The mol. imprinted polymer was immobilized on the NDG layer by the sol-gel technique. In the optimum conditions, the imprinting factor was obtained equal to 4.8, indicating the optimal selectivity of the sensor for the determination of FEX. Differential pulse voltammetry (DPV) was used for the determination of FEX, which exhibited a linear calibration graph of Ip vs. FEX concentration in the range of 5.0 x 10-10-7.8 x 10-6 M (mol L-1). The detection limit of the sensor was calculated equal to 1.5 x 10-10 M, which displayed a superior detection limit when compared with the other electrochem. sensors reported for the FEX determination The developed sensor contained advantages of simple design, satisfactory reproducibility, appropriate determination recoveries and high selectivity. These features permitted the successful application of the sensor for the measurement of FEX in pharmaceutical and biol. samples.

Risk-based screening for prioritisation of organic micropollutants in Swedish freshwater was written by Figuiere, Romain;Waara, Sylvia;Ahrens, Lutz;Golovko, Oksana. And the article was included in Journal of Hazardous Materials in 2022.Name: 2-(4-(1-Hydroxy-4-(4-(hydroxydiphenylmethyl)piperidin-1-yl)butyl)phenyl)-2-methylpropanoic acid The following contents are mentioned in the article:

Concerns about environmental contamination by organic micropollutants (OMPs) are increasing, due to their potential bioaccumulative and toxic properties. This study evaluated the risk posed by OMPs to aquatic ecosystems in Swedish freshwaters. The assessment was based on measured environmental concentrations (MEC) of OMPs in surface waters upstream and downstream of Swedish wastewater treatment plants (WWTPs). A novel optimized risk quotient (RQf) was used to identify potential high-risk substances in the aquatic environment. A secondary objective was to assess the impact of WWTP effluent on aquatic ecosystems using a novel impact factor (I) based on the risk quotient (RQ). Among the 126 substances investigated, four compounds (metformin, N,N-dimethyltetradecylamine, oxazepam, and venlafaxine) were identified as likely to pose a risk to aquatic ecosystems in Swedish surface waters (RQf>1), and five compounds (clindamycin, gemfibrozil, sertraline, o-desmethylvenlafaxine, and diclofenac) were identified as posing a moderate risk to aquatic ecosystems ( 0.1 <RQf<1). WWTP effluent appeared to pose an environmental risk for all recipient sites, but the impact of calculated RQ was site-specific. These results can be used by authorities to prioritise OMPs and contaminated hotspots, in order to decrease neg. impacts on aquatic ecosystems. A novel optimized risk assessment approach for identification of high-concern organic micropollutants in aquatic environments.

Soluble epoxide hydrolase inhibition improves cognitive function and parenchymal artery dilation in a hypertensive model of chronic cerebral hypoperfusion was written by Matin, Nusrat;Fisher, Courtney;Lansdell, Theresa A.;Hammock, Bruce D.;Yang, Jun;Jackson, William F.;Dorrance, Anne M.. And the article was included in Microcirculation (Oxford, United Kingdom) in 2021.HPLC of Formula: 1222780-33-7 The following contents are mentioned in the article:

Objective : Parenchymal arterioles (PAs) regulate perfusion of the cerebral microcirculation, and impaired PA endothelium-dependent dilation occurs in dementia models mimicking chronic cerebral hypoperfusion (CCH). Epoxyeicosatrienoic acids (EETs) are vasodilators; their actions are potentiated by soluble epoxide hydrolase (sEH) inhibition. We hypothesized that chronic sEH inhibition with trifluoromethoxyphenyl-3 (1-propionylpiperidin-4-yl) urea (TPPU) would prevent cognitive dysfunction and improve PA dilation in a hypertensive CCH model. Bilateral carotid artery stenosis (BCAS) was used to induce CCH in twenty-week-old male stroke-prone spontaneously hypertensive rats (SHSRP) that were treated with vehicle or TPPU for 8 wk. Cognitive function was assessed by novel object recognition. PA dilation and structure were assessed by pressure myog., and mRNA expression in brain tissue was assessed by qRT-PCR. TPPU did not enhance resting cerebral perfusion, but prevented CCH-induced memory deficits. TPPU improved PA endothelium-dependent dilation but reduced the sensitivity of PAs to a nitric oxide donor. TPPU treatment had no effect on PA structure or biomech. properties. TPPU treatment increased brain mRNA expression of brain derived neurotrophic factor, doublecortin, tumor necrosis factor-alpha, sEH, and superoxide dismutase 3, Conclusions : These data suggest that sEH inhibitors may be viable treatments for cognitive impairments associated with hypertension and CCH. This study involved multiple reactions and reactants, such as 1-(1-Propionylpiperidin-4-yl)-3-(4-(trifluoromethoxy)phenyl)urea (cas: 1222780-33-7HPLC of Formula: 1222780-33-7).

He vaccination program. two specialized allergy clinics (Nashville, USA, and Gentofte, Denmark) evaluated healthcare workforce members referred forpotential immediate, allergic reactions to the first dose of the PfizerBioNTech SARS-CoV-2 mRNA vaccine, with 13/23,035 (0.06%) and 34/54,567 (0.06%) of vaccinated healthcare workers being referred, resp. Of these 47 total patients referred for potential immediate, allergic reactions, 39 had histories of mild reactions and 8 had histories consistent with anaphylaxis to the first dose of the Pfizer-BioNTech SARS-CoV-2 mRNA vaccine. All 8 went on to have an in-clinic observed second dose administration. Patient demographics, first-dose reaction history, polyethylene glycol (PEG) skin testing, and second dose administration outcome were evaluated. A serum tryptase was obtained in 5/8 patients within the appropriate 30-90 min time frame of their first-dose reaction and none were elevated. The lack of tryptase elevation during suspected first dose anaphylaxis, neg. PEG testing, and observed tolerance of the second dose do not support an IgE-mediated mechanism. Patients who demonstrate an IgE-mediated allergy to PEG would not fall into this category. Although we are still learning about the protective correlates of SARS-CoV-2 immunity, the second dose of the mRNA vaccines is associated with enhanced neutralizing antibody and T-cell responses, suggesting that it could be necessary for a more effective and durable immune response.

Substance use in pregnancy is a global public health problem, both in developed and developing countries. Whereas information is available for major western countries, scarce data are present for the second ones. The objective assessment of pregnancy consumption of xenobiotic is provided by anal. of maternal hair, which can account for gestational consumption, given the possibility to analyze 9 cm hair corresponding to the pregnancy months. Here, we describe an ultra-high-performance liquid chromatog. high-resolution mass spectrometry (UHPLC-HRMS) method used as screening anal. of classic drugs, new psychoactive substances and medications in hair from a cohort of pregnant Mexican women. The UHPLC-HRMS method included Accucore Ph Hexyl (100 x 2.1 mm, 2.6μm, Thermo, USA) column with a gradient mobile phase and a full-scan data-dependent MS2 (ddMS2) mode for substances identification (mass range 100-750 m/z). These results from the first 100 samples disclosed the presence of several undeclared and declared psychoactive substances and medications, being methamphetamine and paracetamol the most prevalent ones found in 20% and 43% cases, resp. In addition, biomarkers of cannabis and tobacco use as well as those of antihistamines and antiemetic drugs were also prevalent. Albeit preliminary, these data confirm the feasibility of hair screening by UHPLC-HRMS to objectively assess xenobiotic consumption in pregnant women with consequent risk of fetal exposure to toxic substances.

In the United States (US), private-supply tapwater (TW) is rarely monitored. This data gap undermines individual/community risk-management decision-making, leading to an increased probability of unrecognized contaminant exposures in rural and remote locations that rely on private wells. We assessed point-of-use (POU) TW in three northern plains Tribal Nations, where ongoing TW arsenic (As) interventions include expansion of small community water systems and POU adsorptive-media treatment for Strong Heart Water Study participants. Samples from 34 private-well and 22 public-supply sites were analyzed for 476 organics, 34 inorganics, and 3 in vitro bioactivities. 63 organics and 30 inorganics were detected. Arsenic, uranium (U), and lead (Pb) were detected in 54%, 43%, and 20% of samples, resp. Concentrations equivalent to public-supply maximum contaminant level(s) (MCL) were exceeded only in untreated private-well samples (As 47%, U 3%). Precautionary health-based screening levels were exceeded frequently, due to inorganics in private supplies and chlorine-based disinfection byproducts in public supplies. The results indicate that simultaneous exposures to co-occurring TW contaminants are common, warranting consideration of expanded source, point-of-entry, or POU treatment(s). This study illustrates the importance of increased monitoring of private-well TW, employing a broad, environmentally informative anal. scope, to reduce the risks of unrecognized contaminant exposures.
