This study evaluated gammaglobulin levels in different lymphoma types at diagnosis and described a subset of mantle cell lymphoma (MCL) patients who presented with substantial polyclonal hypergammaglobulinemia and increased follicular-related and intratumoral Tfh cells. A total of 110 MCL patients were diagnosed in 2014-2019 at the Wilmot Cancer Institute of the University of Rochester Medical Center. By querying their serum protein electrophoresis (SPEP) results around the time of lymphoma diagnosis (approved by the University of Rochester Institutional Review Board), we found that SPEP was performed on 5.4% (6/110) of MCL patients and identified polyclonal hypergammaglobulinemia in 5/6 patients. Available results were found in 99 MCL patients and 90 FL patients at diagnosis and showed that more MCL than FL patients have high protein gaps (MCL range 1.5-7.3 g/ dL vs. FL range 1.7-3.7 g/dL) ( p = 0.03; Mann-Whitney test). These suggest that polyclonal hypergammaglobulinemia is a recurrent feature of MCL but not of FL. Three MCL patients (cases 1-3) with substantial polyclonal hypergammaglobulinemia and complete clin. data available were identified for further investigation. Case 1 displayed a similar increased PD-1 expression in nodular clusters with scattered intra-tumoral staining suggests that MCL patients with and without polyclonal hypergammaglobulinemia have distinct tumor microenvironments. Among the non-neoplastic IGH reads, a median of 6 IGH variable region (IGHV) genes and 22 distinct clonotypes were observed (Figure 2(B,C)), while cases 2 and 3 were outliers, exhibiting use of 38 and 33 IGHV genes, with 1820 and 397 distinct clonotypes, resp. These data indicate the presence of substantial populations of polyclonal B and plasma cell background in a subset of MCL specimens.

The influence of different proton pump inhibitors and potassium-competitive acid blockers on indomethacin-induced small intestinal injury was written by Li, Kemin;Cheng, Xiaoyun;Jin, Rui;Han, Taotao;Li, Jingnan. And the article was included in Journal of Gastroenterology and Hepatology in 2022.HPLC of Formula: 117976-90-6 The following contents are mentioned in the article:

Background and Aim : The influence of gastric acid inhibitors (GAIs) on nonsteroidal anti-inflammatory drug (NSAID)-induced enteropathy is controversial. Herein, the influences of different GAIs on NSAID-induced intestinal injury and the underlying mechanisms are clarified. Methods : Indomethacin (IND; 10 mg/kg/day) was administered to mice to induce small intestinal injury. Disease activity was examined macroscopically and histol. The permeability of small intestine was evaluated by measuring plasma lipopolysaccharide levels. 16S rDNA sequencing was performed to determine the composition of intestinal flora. Results : Among the four GAIs, ilaprazole (IPZ) significantly attenuated IND-induced small intestinal injury and maintained the integrity of the mucosal barrier. Omeprazole (OPZ) and vonoprazan (VPZ) ameliorated ulceration without significant differences, while rabeprazole (RPZ) failed to protect against the injury. To explore the potential mechanism, we investigated changes in the gut microbiota mediated by GAIs. After 5-day administration, GAIs significantly altered the composition of the gut microbiota. The IND group had a significant decrease in alpha diversity compared with the control group, and this decrease was reversed by OPZ and IPZ treatment, resp. After IPZ treatment, the community membership was more assembled in the control group than the IND group. Further, we found that Lactobacillus was significantly increased in the groups of OPZ, IPZ, and VPZ, while Bacteroides was significantly increased in the RPZ group. Conclusion : Our results indicated that GAIs have different influences on the mucosal barrier, possibly by altering the composition of intestinal microbiota, and the impacts mediated by various GAIs in the IND-induced intestinal damage model seem different.

Effect of Imidazolium-Based Ionic Liquids on the Interfacial Tension of the Alkane-Water System and Its Influence on the Wettability Alteration of Quartz under Saline Conditions through Contact Angle Measurements was written by Velusamy, Sugirtha;Sakthivel, Sivabalan;Sangwai, Jitendra S.. And the article was included in Industrial & Engineering Chemistry Research in 2017.Safety of 1-Hexyl-3-methyl-1H-imidazol-3-ium hydrogensulfate The following contents are mentioned in the article:

Depleted matured reservoirs contain almost two-thirds trapped oil, which remains unrecovered even after primary and secondary oil recovery methods. Chem. enhanced oil recovery (EOR) methods involve the usage of chem. agents that improve the mobility of the residual oil by mechanisms involving alteration of wettability, viscous fingering reduction within the pay zone, and interfacial tension (IFT) between interfaces of fluids (oil/water) and rock, followed by reduced capillary forces during flooding. Chem. EOR methods need more research for high saline reservoir conditions. In this work, the effect of six imidazolium ionic liquids (ILs) on the IFT of alkane-water systems and alteration of wettability of quartz surface was investigated as a function of IL concentration (0-10000 ppm) and temperature (288.15, 298.15, 308.15, and 318.15 K). Initially, the effect of the various ILs on the IFT of the alkane-aqueous IL system was studied and compared with the neat alkane-water system. Subsequently, synergistic behavior of the ILs + NaCl (0-200000 ppm NaCl) on the system of alkane-aqueous IL + NaCl was performed and compared with the alkane-aqueous IL system at zero salinity. Thereafter, the wettability alteration of quartz-alkane-aqueous IL and quartz-crude oil-aqueous IL systems, under both zero and high salinity conditions at 298.15 K at atm. pressure, was studied using contact angle measurements. The systems with IL showed an increase of contact angle exhibiting an alteration in the wettability from water wet to oil wet, whereas the systems under saline conditions showed a wettability from oil wet to water wet. A synergistic effect of ILs with salt on IFT reduction and wettability alteration has been detected. It is suggested that longer ILs could be a better option for EOR application.

Different dose of new generation proton pump inhibitors for the treatment of Helicobacter pylori infection: A meta-analysis was written by Gao, Wenwen;Zhang, Xiang;Yin, Yanhui;Yu, Shuwen;Wang, Lu. And the article was included in International Journal of Immunopathology and Pharmacology in 2021.COA of Formula: C18H20N3NaO3S The following contents are mentioned in the article:

The evidence on whether high-dose new generation proton pump inhibitors (PPIs) including rabeprazole and esomeprazole achieve a higher eradication rate of Helicobacter pylori has not been assessed. The primary comparison was eradication and adverse events (AEs) rate of standard (esomeprazole 20 mg bid, rabeprazole 10 mg bid) vs. high-dose (esomeprazole 40 mg bid, rabeprazole 20 mg bid) PPIs. Sub-analyses were performed to evaluate the eradication rate between Asians and Caucasians, clarithromycin-resistance (CAM-R) strains, and clarithromycin-sensitivity (CAM-S) strains of different dose PPIs. We conducted a literature search for randomized controlled trials comparing high-with standard-dose esomeprazole and rabeprazole for H. pylori eradication and AEs. A total of 12 trials with 2237 patients were included. The eradication rate of high-dose PPIs was not significantly superior to standard-dose PPIs regimens: 85.3% vs. 84.2%, OR 1.09 (0.86-1.37), P = 0.47. The high dose induced more AEs than those of the standard dose, but didn’t reach statistical significance (OR 1.25, 95% CI: 0.99-1.56, P = 0.06). Subgroup anal. showed that the difference in eradication rate of PPIs between high- and standard-dose groups were not statistically significant both in Asians (OR 0.99, 95% CI 0.75-1.32, P = 0.97) and Caucasians (OR 1.27, 95% CI 0.84-1.92, P = 0.26). Furthermore, there were similar eradication rates in CAM-S (OR 1.2; 95% CI 0.58-2.5; P = 0.63) and CAM-R strains (OR 1.08; 95% CI 0.45-2.56; P = 0.87) between the standard-and high-dose groups. High and standard dosages of new generation of the PPIs showed similar H. pylori eradication rates and AEs as well as between Asian vs. Caucasian populations, with or without clarithromycin-resistance. However, further studies are needed to confirm.

Contact angles and wettability of ionic liquids on polar and non-polar surfaces was written by Pereira, Matheus M.;Kurnia, Kiki A.;Sousa, Filipa L.;Silva, Nuno J. O.;Lopes-da-Silva, Jose A.;Coutinho, Joao A. P.;Freire, Mara G.. And the article was included in Physical Chemistry Chemical Physics in 2015.Related Products of 478935-29-4 The following contents are mentioned in the article:

Many applications involving ionic liquids (ILs) require the knowledge of their interfacial behavior, such as wettability and adhesion. In this context, herein, two approaches were combined aiming at understanding the impact of the IL chem. structures on their wettability on both polar and non-polar surfaces, namely: (i) the exptl. determination of the contact angles of a broad range of ILs (covering a wide number of anions of variable polarity, cations, and cation alkyl side chain lengths) on polar and non-polar solid substrates (glass, Al-plate, and poly-(tetrafluoroethylene) (PTFE)); and (ii) the correlation of the exptl. contact angles with the cation-anion pair interaction energies generated by the Conductor-like Screening Model for Real Solvents (COSMO-RS). The combined results reveal that the hydrogen-bond basicity of ILs, and thus the IL anion, plays a major role through their wettability on both polar and non-polar surfaces. The increase of the IL hydrogen-bond accepting ability leads to an improved wettability of more polar surfaces (lower contact angles) while the opposite trend is observed on non-polar surfaces. The cation nature and alkyl side chain lengths have however a smaller impact on the wetting ability of ILs. Linear correlations were found between the exptl. contact angles and the cation-anion hydrogen-bonding and cation ring energies, estimated using COSMO-RS, suggesting that these features primarily control the wetting ability of ILs. Furthermore, two-descriptor correlations are proposed here to predict the contact angles of a wide variety of ILs on glass, Al-plate, and PTFE surfaces. A new extended list is provided for the contact angles of ILs on three surfaces, which can be used as a priori information to choose appropriate ILs before a given application.

Intestinal permeability and psychol. stress are considered the key mechanism(s) in functional dyspepsia (FD). Although proton pump inhibitors (PPIs) are commonly used for the treatment of FD, the effect of PPIs on intestinal permeability has not been elucidated. This study investigated the effect of PPI on intestinal permeability under stressed conditions. C57BL/6J mice were subjected to water avoidance stress (WAS) and administered rabeprazole (40 mg/kg) or vehicle treatment (VT). We then evaluated intestinal permeability both in vivo and ex vivo using plasma fluorescein isothiocyanate-dextran and by assessing the paracellular permeability and transepithelial elec. resistance (TEER) in an Ussing chamber, resp. Furthermore, we evaluated the effect of PPI-treated fecal microbiota transplant (FMT) on intestinal permeability in vivo. Microbiota profiles of donor feces were assessed by 16S rRNA gene anal. using MiSeq and QIIME2. In the WAS treatment, PPI significantly enhanced intestinal permeability in vivo compared to that in VT. Moreover, PPI significantly increased paracellular permeability and decreased TEER in the duodenum and jejunum, resp., compared to those in VT under stressed conditions. Moreover, both vasoactive intestinal peptide (VIP) receptor antagonist and ketotifen significantly reversed the effect of PPI on intestinal permeability. Furthermore, PPI-treated FMT significantly increased the intestinal permeability in vivo compared to that in vehicle-treated FMT. Proton pump inhibitors treatment altered the gut microbiota composition, indicating that PPI induced dysbiosis. Under stressed conditions, PPI enhances intestinal permeability via dysbiosis of gut microbiota. Vasoactive intestinal peptide and mast cells are also implicated in the underlying mechanisms.

To discover new nematicides I (n = 1, 2, 3; R = Et, iso-Pr, 4-nitrobenzyl, etc.) a series of novel amide derivatives containing an imidazo[1,2-a]pyridine moeity I were designed and synthesized. Among the title compounds, compounds I (n = 1; R = Pr and n = 3; R = n-decyl (III)) exhibited good nematicidal activities against Aphelenchoides besseyi (rice white-tip nematode), with LC₅₀ values against of 27.3 and 35.9 mg/L, resp., which were superior to that of fosthiazate (45.4 mg/L). Meanwhile, the LC₅₀ value of compound III against Caenorhabditis elegans was 5.7 mg/L, which was superior to that of fosthiazate (77.2 mg/L). Compound III not only binds well to acetylcholinesterase (AChE) of nematodes, but also has a good inhibitory activity against AChE. Thus, AChE may be a potential target of compound III against nematodes. Unexpectedly, compound I (n = 1; R = chloromethyl (IV)) exhibited excellent antibacterial activities with EC₅₀ values of 1.2 and 3.1 mg/L against Xanthomonas oryzae pv. oryzae (Xoo) and Xanthomonas oryzae pv. oryzicola (Xoc), resp., which were superior to those of bismerthiazol (68.6 and 77.1 mg/L) and thiodiazole copper (80.8 and 96.6 mg/L). The curative and protective activities of compound IV against bacterial leaf blight were 37.0% and 36.8% at 50 mg/L, resp., which were higher than those of thiodiazole copper (16.1% and 15.5%). In addition, compound IV may inhibit the growth of Xoo by affecting the production of cell membranes and extracellular polysaccharides.

The relationship between short-term surrogate endpoint indicators and mPFS and mOS in clinical trials of malignant tumors: a case study of approved molecular targeted drugs for non-small-cell lung cancer in China was written by Rui, Mingjun;Wang, Zijing;Fei, Zhengyang;Wu, Yao;Wang, Yingcheng;Sun, Lei;Shang, Ye;Li, Hongchao. And the article was included in Frontiers in Pharmacology in 2022.Name: 4-(5-(Bis(2-chloroethyl)amino)-1-methyl-1H-benzo[d]imidazol-2-yl)butanoic acid The following contents are mentioned in the article:

Due to the initiation of the priority review program in China, many antitumor drugs have been approved for marketing based on phase II clin. trials and short-term surrogate endpoint indicators. This study used approved targeted drugs for the treatment of non-small-cell lung cancer (NSCLC) in China as an example to evaluate the association between short-term surrogate endpoints [objective response rate (ORR) and disease control rate (DCR)] and median progression-free survival (mPFS) and median overall survival (mOS). Five databases, i.e., MEDLINE, Embase, Cochrane Library, China National Knowledge Infrastructure (CNKI), and Wanfang Data were searched, for phase II or phase III clin. trials of all mol. targeted drugs that have been marketed in China for the treatment of NSCLC. After screening the literature and extracting information, both univariate and multivariate linear regression were performed on the short-term surrogate indicators and mPFS and mOS to explore the relationship. A total of 63 studies were included (25 studies with only ORR, DCR, and mPFS and 39 studies with ORR, DCR, mPFS, and mOS). In terms of the targeted drugs for the treatment of NSCLC, in addition to the good but not excellent linear relationship between DCR and mOS (0.4 < R2 adj = 0.5653 < 0.6), all other short-term surrogate endpoint indicators had excellent linear relationships with mPFS and mOS (R2 adj≥0.6), while mPFS and mOS had the most excellent linear relationships (R2 adj = 0.8036). For targeted drugs for the treatment of NSCLC, short-term surrogate endpoint indicators such as ORR and DCR may be reliable surrogate indicators for mPFS and mOS. However, whether short-term surrogate endpoint indicators can be used to predict final endpoints remains to be verified.

Multiple available combinations of proteasome inhibitors, immunomodulators (IMIDs), and monoclonal antibodies are shifting the relapsed/refractory multiple myeloma (RRMM) treatment landscape. Lack of head-to-head trials of triplet regimens highlights the need for real-world (RW) evidence. We conducted an RW comparative effectiveness anal. of bortezomib (V), carfilzomib (K), ixazomib (I), and daratumumab (D) combined with either lenalidomide or pomalidomide plus dexamethasone (Rd or Pd) in RRMM. A retrospective cohort of patients initiating triplet regimens in line of therapy (LOT) ≥ 2 on/after 1/1/2014 was followed between 1/2007 and 3/2018 in Optum’s deidentified US electronic health records database. Time to next treatment (TTNT) was estimated using Kaplan-Meier methods; regimens were compared using covariate-adjusted Cox proportional hazard models. Seven hundred forty-one patients (820 patient LOTs) with an Rd backbone (VRd, n = 349; KRd, n = 218; DRd, n = 99; IRd, n = 154) and 348 patients (392 patient LOTs) with a Pd backbone (VPd, n = 52; KPd, n = 146; DPd, n = 149; IPd, n = 45) in LOTs ≥2 were identified. More patients ≥75 years received IRd (39.6%), IPd (37.8%), and VRd (36.7%) than other triplets. More patients receiving VRd/VPd were in LOT2 vs other triplets. Unadjusted median TTNT in LOT ≥ 2: VRd, 13.9; KRd, 8.7; IRd, 11.4; DRd, not estimable (NE); and VPd, 12.0; KPd, 6.7; IPd, 9.5 mo; DPd, NE. In covariate-adjusted anal., only KRd vs DRd was associated with a significantly higher risk of next LOT initiation/death (HR 1.72; P = 0.0142); no Pd triplet was significantly different vs DPd in LOT ≥ 2.

Results : The intention-to-treat and per-protocol eradication rates of V-AS were 75.8% (95% confidence interval [CI]: 57.7-88.9%) and 83.3% (95% CI: 65.3-94.4%), resp. The resp. eradication rates of PPI-AS were 53.3% (95% CI: 34.3-71.7%) and 57.1% (95% CI: 37.2-75.5%). In per-protocol analyses, the eradication rate of the V-AS group was significantly higher than that of the PPI-AS group (P = 0.043); however, no significant differences were observed in intention-to-treat analyses (P = 0.071). Questionnaire scores did not differ significantly between the groups. Conclusions : The findings suggest that 7-day triple therapy with vonoprazan, amoxicillin, and sitafloxacin is more effective than proton-pump inhibitor, amoxicillin, and sitafloxacin as a third-line regimen for eradicating H. pylori. This study involved multiple reactions and reactants, such as Sodium 2-(((4-(3-methoxypropoxy)-3-methylpyridin-2-yl)methyl)sulfinyl)benzo[d]imidazol-1-ide (cas: 117976-90-6Category: imidazoles-derivatives).

Sodium 2-(((4-(3-methoxypropoxy)-3-methylpyridin-2-yl)methyl)sulfinyl)benzo[d]imidazol-1-ide (cas: 117976-90-6) belongs to imidazole derivatives. Among the different heterocyclic compounds, imidazole is better known due to its broad range of chemical and biological properties. Imidazole has become an important synthon in the development of new drugs. Imidazole derivatives have antibacterial, antifungal and anticancer functionality. It interacts with DNA and also binds to protein and stops cell division.Category: imidazoles-derivatives
