Singh, Santosh Kumar; Dey, Swapan; Schneider, Manfred P.; Nandi, Sukhendu published the artcile< D-Mannitol based surfactants for cosmetic and food applications and hydrogels to produce stabilized Ag nanoparticles>, Recommanded Product: (9Z,12Z)-Methyl octadeca-9,12-dienoate, the main research area is mannitol surfactant silver nanoparticle hydrogel cosmetic food application.

A series of mannitol based amphiphiles were synthesized based mainly on renewable resources. All these amphiphiles are surfactants with excellent foaming abilities and low CMC values. Their surface-active properties (foaming and emulsifying) with the variation of hydrocarbon chains have been thoroughly investigated. Notably, they all produce very stable hydrogels. The thermal stability of the hydrogel is strongly influenced by the length of the hydrocarbon chain of the lipophilic part of the mols. Different spectroscopic and microscopic techniques were used to study the morphol. of the hydrogels and the driving force leading to hydrogel formation. Besides that, such hydrogel was used as a scaffold to stabilize in situ formed silver nanoparticles (Ag NPs) through their capping action. Such synthesized Ag NPs have a narrow size distribution with a mean population of around 13.5 nm, as confirmed by a high-resolution transmission electron microscopy study.

Owa, Takashi published the artcile< Chemistry and biology of a series of antitumor sulfonamides: exploiting transcriptomic and quantitative proteomic analyses for exploring drug gable chemical space>, Electric Literature of 112-63-0, the main research area is cancer antitumor sulfonamide derivative SAR preparation.

Sulfolnamide-focused compound libraries have been synthesized in our laboratories for biol. evaluation using antitumor phenotypic screens such as cancer cell proliferation assay, flow cytometric cell cycle anal., and rat aorta tube formation assay. Among thousands of sulfonamide compounds evaluated, E7010 (a microtubule depolymerizing agent), E7070 (a G1 phase cell cycle inhibitor), and E7820 (an antiangiogenesis agent) have progressed to clin. trials, thereby demonstrating some objective responses in cancer patients so far. The sequential discovery of these drug candidates allowed us to carry out a research approach of forward chem. genetics, in which phenotypically bioactive compounds are selected from a large collection of small mols. and then utilized for understanding the functions of their protein partners and relevant biol. pathways via target identification. This paper describes our attempt using oligonucleotide microarray and quant. proteomic analyses not only for identifying drug targets and downstream pathways applicable to biomarkers but also for exploring drug gable chem. space in medicinal chem. research.

Van Welzen, Berend J.; Smit, Colette; Boyd, Anders; Lieveld, Faydra I.; Mudrikova, Tania; Reiss, Peter; Brouwer, Annemarie E.; Hoepelman, Andy I. M.; Arends, Joop E. published the artcile< Decreased all-cause and liver-related mortality risk in HIV/hepatitis B virus coinfection coinciding with the introduction of tenofovir-containing combination antiretroviral therapy>, Synthetic Route of 112-63-0, the main research area is tenofovir antiretroviral therapy human immunodeficiency virus Hepatitis B; HIV; coinfection; hepatitis B virus; liver-related mortality; tenofovir.

Background:The development of efficacious combination antiretroviral therapy (cART) has led to a dramatic decrease in mortality in HIV-pos. patients. Specific data on the impact in HIV/hepatitis B virus (HBV)-coinfected patients are lacking. Methods:In this study, all-cause and cause-specific mortality risks stratified per era of diagnosis are investigated. Data were analyzed from HIV/HBV-coinfected patients enrolled in the ATHENA cohort between Jan. 1, 1998, and Dec. 31, 2017. Risk for (cause-specific) mortality was calculated using Cox proportional hazard regression anal., comparing patients diagnosed before 2003 with those diagnosed ≥2003. Risk factors for all-cause and liver-related mortality were also assessed using Cox proportional hazard regression anal. Results:A total of 1301 HIV/HBV-coinfected patients were included (14 882 person-years of follow-up). One-hundred ninetyeight patients (15%) died during follow-up. The adjusted hazard ratio (aHR) for all-cause mortality in patients diagnosed in or after 2003 was 0.50 (95% CI, 0.35-0.72) relative to patients diagnosed before 2003. Similar risk reduction was observed for liver-related (aHR, 0.29; 95% CI, 0.11-0.75) and AIDS-related mortality (aHR, 0.44; 95% CI, 0.22-0.87). Use of a tenofovir-containing regimen was independently associated with a reduced risk of all-cause and liver-related mortality. Prior exposure to didanosine/stavudine was strongly associated with liver-related mortality. Ten percent of the population used only lamivudine as treatment for HBV. Conclusions:All-cause, liver-related, and AIDS-related mortality risk in HIV/HBV-coinfected patients has markedly decreased over the years, coinciding with the introduction of tenofovir. Tenofovir-containing regimens, in absence of major contraindications, should be strongly encouraged in this population.

The one-pot protocol began with rapid and selective electrodimerization of the amide using n-Bu4NI (TBAI) as an electrocatalyst. The reaction proceeded further in the absence of current via Zn catalyzed C-N bond activation of the amide dimer followed by its coupling with phenol to form the phenolic esters I [R = 4-Me, 2,4-di-F, 2-MeO, etc.; R1 = Et, Ph, 4-ClC6H4, etc.]. The present methodol. was ligand-free and took place under mild reaction conditions. This transformation incorporated a wide variety of phenols and amide substrates leading to the formation of functionalized esters highlighting its versatility.

Whang, T.-J.; Wang, Y.-T.; Wu, Y.-P.; Wang, Y.-S.; Tsai, M.-C.; Huang, D.-S. published the artcile< Assessment of baseline toxicity of mono-cyclic aromatic compounds by Pseudomonas initial oxygen uptake assay>, Computed Properties of 112-63-0, the main research area is QSAR mono cyclic aromatic compound toxicity hydrophobicity electrophilicity.

The objective of this study was to develop quant. structure-activity relationships (QSARs) for the toxicity of mono-cyclic aromatic compounds in the Pseudomonas putida initial oxygen uptake assay. The QSARs were developed using response-surface based on descriptors for chem. hydrophobicity (log P) and electrophilicity (LUMO). The model (± 0.011)log P-0.389(± 0.013)LUMO-2.131(± 0.031);,R2 = 0.941,R2adj = 0.940, s= 0.119,F= 1206 led the authors to conclude that the polar and non-polar narcotics were statistically indistinguishable. Pentafluorophenol, pentachlorophenol and most dinitrophenols classified as weak acid respiratory uncouplers in literature fit well into this model when they were treated as their corresponding phenoxides. This latter result suggests that the action mechanism of these phenols should be reevaluated.

Han, Kai; Lin, Qizhao; Liu, Minghou; Meng, Kesheng; Ni, Zhanshi; Liu, Yu; Tian, Junjian; Qiu, Zhicong published the artcile< Experimental study on the micro-explosion characteristics of biodiesel/1-pentanol and biodiesel/ methanol blended droplets>, COA of Formula: C19H34O2, the main research area is biodiesel 1 pentanol methanol droplet microexplosion.

Alcs. and biodiesel are promising alternative biofuels for their excellent physicochem. properties and renewable property. Compared with low-carbon alcs., high-carbon 1-Pentanol has better fuel characteristics. The objective of the present study was to reveal the effects of different 1-pentanol addition ratios on the micro-explosion characteristics of blended droplets. Single droplet suspension experiment under atm. pressure and 700°C was carried out, and results were compared with that of methanol. The droplet had three initial diameters (1.281, 1.451, and 1.537 mm). The droplet evaporation images were recorded at 500 fps with a resolution of 1024 x 1024 pixels by a high-speed video camera, and the corresponding droplet diameter in the evaporation process was obtained by a MATLAB program. A new dimensionless micro-explosion intensity was proposed. The results showed that when the 1-pentanol volume content was 50% (B50P50), the micro-explosion number and total micro-explosion intensity reached the maximum With the increase of initial droplet diameter, the micro-explosion number, total micro-explosion intensity and droplet lifetime increased. Compared with biodiesel/1-pentanol blended droplets, biodiesel/methanol ones had better micro-explosion characteristics and shorter droplet lifetime. White fog formed in the evaporation process of blended droplets and pure biodiesel ones. In short, the addition of methanol and 1-pentanol caused micro-explosions, changed the evaporation behavior of biodiesel, and reduced droplet lifetime, which could be considered as an alternative fuel blended with biodiesel.

Background: There is very little data on long-term immune recovery responses in patients on suppressive antiretroviral therapy (ART) in the setting of sub-Saharan Africa (SSA). Thus, we sought to determine CD4+ T-cell, CD8+ T-cell and CD4/CD8 ratio responses in a cohort of HIV infected individuals on sustained suppressive ART followed up for more than a decade. Methods: The cohort comprised adult patients who started ART between 2001 and 2007 and followed for up to 14 years. Trends in median CD4+ T-cells, CD8+ T-cells and CD4/CD8 ratio were reviewed retrospectively. Poisson regression models were used to identify factors associated with achieving normalized T-cell biomarkers. Kaplan-Meier curves were used to estimate the probability of attaining normalized counts while on suppressive ART. Results: A total of 227 patients with a median duration of follow-up on ART of 12 (IQR: 10.5-13.0) years were included. CD4 cell count increased from baseline median of 138 cells (IQR: 70-202) to 555 cells (IQR: 417-830). CD4 cell increased continuously up until 5 years, after which it plateaued up until 14 years of follow up. Only 69.6% normalized their CD4 cell count within a median of 6.5 (IQR: 3.0-10.5) years.
