Sasanam, Sirinapa published the artcileProperties and volatile profile of process flavorings prepared from D-xylose with glycine, alanine or valine by direct extrusion method, COA of Formula: C13H16O, the main research area is xylose glycine alanine valine flavoring.

This study investigated the production of process flavorings by direct extrusion method using a model system consisted of 80(weight/weight) D-xylose and glycine, alanine, or valine at 20(weight/weight). The extruder′s barrel temperatures were controlled at 65, 80, and 50 °C. The aroma compounds in the obtained products were analyzed by gas chromatog.-mass-spectrometry (GC-MS). Some properties relevant for food application including solubility, water absorption index, and oil absorption capacity were also determined Characteristics and color profiles of the extruded flavorings were similar to the process flavorings obtained by conventional method (reflux method). Process flavorings using valine presented the highest L* value (lightness, 59.6), water absorption index, water solubility index, and oil absorption capacity at 3.26 and 1.76 g/g sample, and 2.72 g oil/g, resp. Use of glycine resulted in the highest frequency of just-about-right for the taste (60), while alanine gave the highest frequency for odor (53.3). The extruded flavorings exhibited sweet, sour, and meaty flavor with 13 and 12 volatile compounds from glycine and alanine. When valine, the higher mol. weight amino acid in the bitter group was used, 37 volatiles with more complex flavor profiles were found, among of which, the compound 5-methyl-2-phenylhex-2-enal, which exhibits a chocolate odor, was also present. Sweet and meaty process flavorings could be produced by direct extrusion using D-xylose and glycine, alanine, and valine, with low moisture content at only 5by weight The information obtained about their phys., taste and sensory properties, volatile profiles, are beneficial for further use in industrial applications.

Awasthi, Garima published the artcileDe-novo hybrid protein design for biodegradation of organophosphate pesticides, SDS of cas: 104-01-8, the main research area is .

In the present investigation, we attempted to design a protocol to develop a hybrid protein with better bioremediation capacity. Using in silico approaches, a Hybrid Open Reading Frame (Hybrid ORF) is developed targeting the genes of microorganisms known for degradation of organophosphates. Out of 21 genes identified through BLAST search, 8 structurally similar genes (opdA, opd, opaA, pte RO, pdeA, parC, mpd and phnE) involved in biodegradation were screened. Gene conservational anal. categorizes these organophosphates degrading 8 genes into 4 super families i.e., Metallo-dependent hydrolases, Lactamase B, MPP and TM_PBP2 superfamily. Hybrid protein structure was modeled using multi-template homol. modeling (3S07_A; 99%, 1P9E_A; 98%, 2ZO9_B; 33%, 2DXL_A; 33%) by Schrödinger software suit version 10.4.018. Structural verification of protein models was done using Ramachandran plot, it was showing 96.0% residue in the favored region, which was verified using RAMPAGE. The phosphotriesterase protein was showing the highest structural similarity with hybrid protein having raw score 984. The 5 binding sites of hybrid protein were identified through binding site prediction. The docking study shows that hybrid protein potentially interacts with 10 different organophosphates. The study results indicate that the hybrid protein designed has the capability of degrading a wide range of organophosphate compounds

Bassal, Ravit published the artcileRisk Factors for Multiple Infections with Salmonella, Shigella, and Campylobacter in Single Individuals Identified in Israel between 1999 and 2020: A Case-Case Control Study., Quality Control of 86-51-1, the main research area is .

BACKGROUND: Salmonella, Shigella, and Campylobacter are highly prevalent among children. Reports on risk factors of patients infected with all three pathogens, not simultaneously, are scarce. OBJECTIVES: To identify risk factors for multiple infection with Salmonella, Shigella, and Campylobacter in the same child. METHODS: Using the Israel Sentinel Laboratory-Based Surveillance Network, we conducted a retrospective observational case-case-control study among children aged 0-9 years. A case was defined as a child infected with Salmonella, Shigella, and Campylobacter at different occasions between January 1999 and December 2020. A control was defined as a child infected with a single pathogen once, during the same period. Logistic regression models were applied to determine the association between multiple infections and demographic characteristics. RESULTS: We identified 109 cases (0.1%) infected with Salmonella, Shigella, and Campylobacter, and 86,511 controls (99.9%) infected with only one bacteria type. In a multivariable analysis, we showed that being Jewish (odds ratio [OR] 2.4, 95% confidence interval [95%CI] 1.3-4.4), having residency in Jerusalem (OR 3.2, 95%CI 1.3-7.7), or in the southern district (OR 3.7, 95%CI 1.5-8.8) were independent risk factors for multiple infection. CONCLUSIONS: Although very rare, non-simultaneous infection with multiple bacteria does occur in Israel. National and local authorities should promote programs to encourage proper hygiene practices, which are culture-adjusted.

Pan, Hun-Shan published the artcileTotal laparoscopic hysterectomy (TLH) versus coagulation of uterine arteries (CUA) at their origin plus total laparoscopic hysterectomy (TLH) for the management of myoma and adenomyosis., Quality Control of 1205-17-0, the main research area is .

We tried to evaluate the relative feasibility, surgical duration and complications of total laparoscopic hysterectomy (TLH) versus coagulation of uterine arteries at their origin (CUA) plus total laparoscopic hysterectomy for the management of myoma and adenomyosis, and to compare the estimated blood loss for both procedures. A total of 123 patients underwent TLH or CUA plus TLH for the treatment of symptomatic myoma and adenomyosis. Sixty-four women underwent TLH, whilst 68 women underwent coagulation of uterine arteries at their origin plus TLH. The mean weight and volume of the uterus as determined following TLH was 288.1+/-102.4 gm (range 182.1 approximately 396.2 gm.) and 451+/-340.6 cm(3) (range 107.4 approximately 792), respectively. The mean weight of the uterus following CUA plus TLH was 269.1+/-151.7 gm (range 215.8 approximately 430.1) whilst the mean uterine volume was 472.7+/-377.8 cm(3) (range 93.7 approximately 851.2). No significant differences with respect to surgical duration (95 vs. 96.5 minutes TLH vs. CUA + TLH; p>0.05), blood loss (177.2+/-80.1 ml for TLH and 154.9+/-30.21 ml for CUA+TLH; p>0.05) and mean+/-SD preoperative (12.05+/-1.70 gm/dl for TLH and 12.14+/-1.38 gm/dl for CUA+TLH; p>0.05) and post-operative hemoglobin level (11+/-1.03 for TLH and 11+/-1.49 for CUA + TLH; p>0.05) were observed between the two study groups. The blood loss for TLH is comparable to that for the CUA plus TLH procedure.

Bae, Eun Jung published the artcilePeripheral Selective Oxadiazolylphenyl Alanine Derivatives as Tryptophan Hydroxylase 1 Inhibitors for Obesity and Fatty Liver Disease, Recommanded Product: 4-Methoxyphenylacetic acid, the main research area is oxadiazolylphenyl alanine derivative preparation TPH1 inhibitor obesity fatty liver.

Tryptophan hydroxylase 1 (TPH1) has been recently suggested as a promising therapeutic target for treating obesity and fatty liver disease. A new series of 1,2,4-oxadiazolylphenyl alanine derivatives were identified as TPH1 inhibitors. Among them, compound 23a was the most active in vitro, with an IC50 (half-maximal inhibitory concentration) value of 42 nM, showed good liver microsomal stability, and showed no significant inhibition of CYP and hERG. Compound 23a inhibited TPH1 in the peripheral tissue with limited BBB penetration. In high-fat diet-fed mice, 23a reduced body weight gain, body fat, and hepatic lipid accumulation. Also, 23a improved glucose intolerance and energy expenditure. Taken together, compound 23a shows promise as a therapeutic agent for the treatment of obesity and fatty liver diseases.

Yuan, Rui published the artcileSynthesis of 1,7-bis (N-substituted-aminomethyl)-2,8-dihydroxy-Troger’s bases and their application in Aldol-Ullmann reaction, Quality Control of 86-51-1, the main research area is aminomethyl dihydroxy Troger base preparation anti tumor human; hydroxylcoumarin electrophile Aldol Ullmann.

1,7-Bis (N-substituted-aminomethyl)-2,8-dihydroxy-Troger’s bases I (R = CH3, n-C4H9, C6H11, etc.) were synthesized and used as efficient organocatalyst for the Aldol reaction of 4-hydroxylcoumarin and 2-benzylidenemalononitrile (or Me (ethyl)-2-cyano-3-phenylacrylate) to afford 2-amino-4-aryl-5-oxo-4H,5H-pyrano[3,2-c]chromene-3-carbonitriles II (R1 = H, p-F, p-OCH3, etc.; R2 = CN, COOMe, COOEt). Subsequently, they were used as the efficient ligand to promote the Pd-catalyzed Aldol-Ullmann reaction to give III (R = 4-OH, 2-OCH3, 4-F, etc.) and IV (R = 5-CH3, 5-OCH3, 5-Cl, etc.), resp. The anti-cancer activity on human three pos. breast cancer cells (MCF-7), human three neg. breast cancer cells (MDA-MB-231), human hepatoma cells (HepG2), human hepatoma cells (MHCC-97H) and cytotoxicity on human hepatocyte cells (LO2) of catalyst I and all products in vitro were evaluated. I (R = CH3) had selective inhibition (inhibition rate>30%) on MCF-7 cells while I (R = 1-phenylmethyl) and I (R = pyridin-2-methyl) had selective inhibition on MDA-MB-231 cells. II (R1 = 3,4,5-(OCH3)3; R2 = CN) had strong inhibitory effects on three kinds of cancer cells except MDA-MB-231 while II (R1 = p-Br; R2 = CN), II (R1 = 2,4-Cl2; R2 = CN), II (R1 = o-F; R2 = CN) and II (R1 = o-Br; R2 = CN) had strong inhibitory effects on four kinds of cancer cells. However, all the compounds showed cytotoxicity to normal LO2 cells which prompts the necessary of structure modification to reduce the toxicity.

Yang, Heng published the artcileDBU-Promoted Intramolecular Crossed Aldol Reaction: A Facile Access to Indane-Fused Pyrrolidine, Application In Synthesis of 86-51-1, the main research area is DBU catalyst intramol cross aldol addition; indane fused pyrrolidine preparation.

A new strategy for the facile synthesis of indane-fused pyrrolidines through DBU-promoted intramol. crossed aldol reaction has been developed. The efficiency, compatibility and practicality of this method were demonstrated by a broad substrate scope, mild reaction conditions and gram-scale synthesis. The further derivatizations of the synthesized diastereoisomers I and II were performed for arylation, alkenylation, amination and etherification, showing high diastereoselectivities. Deuterium labeling experiment suggests a possible carbocation process which leads to the high diastereoselectivity during the transformations of I and II. Based on this strategy, the 5-HT2C agonist III and the antihypertensive agent IV were successfully synthesized through a three-step synthetic pathway. This new strategy potentially enables a wide exploration of these indane-fused derivatives applied for pharmaceuticals and related fields.

Quelal-Vasconez, Maribel Alexandra published the artcileAutomatic and non-targeted analysis of the volatile profile of natural and alkalized cocoa powders using SBSE-GC-MS and chemometrics, Computed Properties of 21834-92-4, the main research area is alkalized cocoa powder volatile profile SBSE GC MS chemometrics; Alkalized cocoa powder; Chemometrics; PARAFAC2; PLS-DA; SBSE-GC–MS; Volatile compounds.

A total of 56 key volatile compounds present in natural and alkalized cocoa powders have been rapidly evaluated using a non-target approach using stir bar sorptive extraction gas chromatog. mass spectrometry (SBSE-GC-MS) coupled to Parallel Factor Anal. 2 (PARAFAC2) automated in PARADISe. Principal component anal. (PCA) explained 80% of the variability of the concentration, in four PCs, which revealed specific groups of volatile characteristics. Partial least squares discriminant anal. (PLS-DA) helped to identify volatile compounds that were correlated to the different degrees of alkalization. Dynamics between compounds such as the acetophenone increasing and toluene and furfural decreasing in medium and strongly alkalized cocoas allowed its differentiation from natural cocoa samples. Thus, the proposed comprehensive anal. is a useful tool for understanding volatiles, e.g., for the quality control of cocoa powders with significant time and costs savings.
