Eggs are one of the most nutritious products on a daily basis. The objective of present research is to investigate the impact of coatings on improving storage time and internal quality of eggs. Coating treatments included control (C), coated with chickpea protein isolate (CPI), coated with PI containing Satureja hortensis (CPISH), coated with PI containing Satureja mutica (CPISM). Internal quality was assessed by air cell depth, shell strength, weight loss, haugh unit, yolk and albumen pH, yolk index, microbial evaluation and scanning electron microscope. The weight loss increased during storage and its highest value was 6.12%. Edible coatings (CPI, CPISH, CPISM) preserved internal quality according to the haugh unit, yolk index and pH over 4 wk (20°C) compared with C. Haugh unit (5.04), yolk index (0.31), albumen (9.51) and yolk pH (7.04) were detected in C after 7 wk. CPISH and CPISM protected shell is observed by scanning electron microscope and these coatings affected the internal quality and were appropriate alternatives to extend storage.

Yamauchi, Takafumi published the artcileMachine learning approaches to predict gestational age in normal and complicated pregnancies via urinary metabolomics analysis, Application of 3-Hydroxyphenylacetic acid, the publication is Scientific Reports (2021), 11(1), 17777, database is CAplus and MEDLINE.

The elucidation of dynamic metabolomic changes during gestation is particularly important for the development of methods to evaluate pregnancy status or achieve earlier detection of pregnancy-related complications. Some studies have constructed models to evaluate pregnancy status and predict gestational age using omics data from blood biospecimens; however, less invasive methods are desired. Here we propose a model to predict gestational age, using urinary metabolite information. In our prospective cohort study, we collected 2741 urine samples from 187 healthy pregnant women, 23 patients with hypertensive disorders of pregnancy, and 14 patients with spontaneous preterm birth. Using gas chromatog.-tandem mass spectrometry, we identified 184 urinary metabolites that showed dynamic systematic changes in healthy pregnant women according to gestational age. A model to predict gestational age during normal pregnancy progression was constructed; the correlation coefficient between actual and predicted weeks of gestation was 0.86. The predicted gestational ages of cases with hypertensive disorders of pregnancy exhibited significant progression, compared with actual gestational ages. This is the first study to predict gestational age in normal and complicated pregnancies by using urinary metabolite information. Minimally invasive urinary metabolomics might facilitate changes in the prediction of gestational age in various clin. settings.

Pourafshar, Shirin published the artcileUrine and plasma metabolome of healthy adults consuming the DASH (dietary approaches to stop hypertension) diet: a randomized pilot feeding study, HPLC of Formula: 621-37-4, the publication is Nutrients (2021), 13(6), 1768, database is CAplus and MEDLINE.

We aimed to identify plasma and urine metabolites altered by the Dietary Approaches to Stop Hypertension (DASH) diet in a post-hoc anal. of a pilot feeding trial. Twenty adult participants with un-medicated hypertension consumed a Control diet for one week followed by 2 wk of random assignment to either Control or DASH diet. Non-missing fasting plasma (n = 56) and 24-h urine (n = 40) were used to profile metabolites using untargeted gas chromatog./mass spectrometry. Linear models were used to compare metabolite levels between the groups. In urine, 19 identifiable untargeted metabolites differed between groups at p < 0.05. These included a variety of phenolic acids and their microbial metabolites that were higher during the DASH diet, with many at false discovery rate (FDR) adjusted p < 0.2. In plasma, eight identifiable untargeted metabolites were different at p < 0.05, but only gamma-tocopherol was significantly lower on DASH at FDR adjusted p < 0.2. The results provide insights into the mechanisms of benefit of the DASH diet.

Ren, Shen published the artcileDesign, synthesis and evaluation of 2,2-dimethyl-1,3-dioxolane-4,5-dicarboxylic acid derivatives as neuroimmunophilin ligands, Quality Control of 101-98-4, the publication is Zhongguo Yaowu Huaxue Zazhi (2007), 17(1), 1-7, 12, database is CAplus.

A method for the synthesis of the title compounds is reported here. Both, the sequence and conformation of the FK506-binding site in FKBPs (FK506 binding proteins) family are highly conserved. According to this characteristic of FKBPs and the structural feature of ligands binding to FKBP12, CADD (computer-aided drug design) was employed to design and virtually screen novel 2,2-dimethyl-1,3-dioxolane-4,5-5-dicarboxylic acid derivatives These compounds were synthesized by a liquid-phase synthetic method. A model of chick embryos dorsal root ganglion (DRG) cultures free of serum and a model of NG108-15 cell injured by H₂O₂ were applied to evaluate neurotropic activity of these target compounds Thus, 27 target compounds were synthesized. In cultured chick DRGs, N-[[(4R,5R)-5-[[(cyclohexyl)amino]carbonyl]-2,2-dimethyl-1,3-dioxolan-4-yl]carbonyl]-L-aspartic acid di-Et ester produced a little neurotrophic effect and promoted neurite outgrowth in vitro. In the model of H₂O₂-induced NG108 cell damage, N-[[(4R,5R)-2,2-dimethyl-5-[[(phenylmethyl)amino]carbonyl]-1,3-dioxolan-4-yl]carbonyl]-L-serine Et ester showed a significantly protective effect on an NG 108 cell.

Tan, Hongbo published the artcileEffect of organic alkali on compressive strength and hydration of wet-grinded granulated blast-furnace slag containing Portland cement, HPLC of Formula: 122-20-3, the publication is Construction and Building Materials (2019), 10-18, database is CAplus.

In this study, a com. available ground granulated blast-furnace slag (GGBS) was further processed by wet grinding, and WGGBS (wet-grinded GGBS) slurry with superfine particles was obtained. To avoid self-hydration of slag and augment the grinding efficiency, one com. available polycarboxylate superplasticizer was added. The binder, composed of 10.0% cement and 90.0% WGGBS with the addition of 0.05% triethanolamine (TEA) and 0.05% triisopropanolamine (TIPA), was designed; the cement was added to provide alkali environment and calcium ions, and organic alkali was used to promote the dissolution of GGBS. The compressive strength of mortar and hydration mechanism was investigated. The results showed that wet grinding exhibited high grinding efficiency; D(50) value of particle size distribution of WGGBS was reduced from 18μm to 2.10μm by wet grinding for one hour. Compressive strength of hardened WGGBS mortar was 20 MPa and 28 MPa at 7 d and 28 d, and 10% cement replacement ratio of the WGGBS increased the strength to 24.6 MP at 7 d and 32.2 MPa at 28 d. Furthermore, in C-WGGBS, 0.05% TEA increased the 7 d strength by 23%, with the value of 30.27 MPa, but 0.05%TIPA slightly reduced it to 23.5 MPa, with a decrease by 5%. Mechanism behind the increase was due to the accelerated formation of hydrotalcite-like phase, despite the retarding effect on formation of C-(A)S-H gel; the slight decline by TIPA was mainly because of the retarding effect of formation of C-(A)S-H gel as well as its air-entraining effect. Moreover, both TEA and TIPA increased the 28 d strength of cement-WGGBS system, because TEA and TIPA were able to facilitate ferric and aluminum dissolution and expedite the formation of C-(A)S-H gel as well as hydrotalcite-like phase. Addnl., it was worth noting that 0.05% TEA could make 28 d strength of the binder, composed of only 10% cement, reach 43.7 MPa, in accordance with the requirement of 42.5 grade cement.

Ihsan, Mohammad published the artcileGenetic diversity in nutritional composition of oat (Avena sativa L.) germplasm reported from Pakistan, COA of Formula: C8H8O3, the publication is Saudi Journal of Biological Sciences (2022), 29(3), 1487-1500, database is CAplus and MEDLINE.

In the present study, 30 potential germplasm of oat (Avena sativa L.) were subjected to proximate, elemental, and HPLC anal. to provide a scientific basis to genetic diversity present among them. The extracts of the selected germplasms were also evaluated for their antioxidant potentials through DPPH and ABTS assays. Proximate anal. showed protein contents to be in the range 8.35-17.72% with the highest protein contents in the accession line 22,365 (17.72 ± 0.38%). The genotype-725 showed the highest carbohydrate, and dry matter (53.35 ± 0.01 and 93.50 ± 0.07% resp.) contents whereas, the germplasm-830 contained the highest fat (7.88 ± 0.12%) contents while the highest moisture contents were there in germplasm-22348 (11.95 ± 0.06%). The crude fiber contents (19.67 ± 0.19%) were found high in germplasm-832. The mentioned contents were also correlated to each other where a neg. (-0.431*) correlation was noted for crude protein and carbohydrate while ash content to crude protein has a pos. (0.38*) correlation. A pos. and a neg. correlation were there in Crude fats/crude protein (0.30*) and crude fats/moisture contents (-0.39*) resp. Principal component anal. showed an Eigenvalue of 0.76 with a total variation of 85.01% when applied to proximate components. Based on cluster anal. to proximate composition all the oat germplasms were divided into 5 sub-clusters, where accession numbers 769 and 817 were found to be the most diverse genotypes. The elemental anal. confirmed the presence of magnesium (2.89-7.62 mg/L), sodium (3.71-8.03 mg/L), manganese (0.93-3.71 mg/L), copper (0.35-3.36 mg/L), iron (2.15-6.82 mg/L), zinc (1.30-3.37 mg/L), chromium (0.37-3.34 mg/L), and potassium (50.70-59.60 mg/L) in the selected germplasms. Principal component anal. for elemental composition showed the total variation of 73.75% with the Eigenvalue of 0.97. Cluster anal. on an elemental basis divided all the oat germplasms into 7 sub-clusters where accession numbers 769 and 22,350 were found to be the most diverse germplasm. Phytochem. anal. performed through HPLC resulted in the identification of nine possible compounds (malic acid, epigallocatechin gallate, quercetin, morin, ellagic acid, catechin hydrate, rutin, pyrogallol, and mandelic acid) in various germplasm of oat. A concentration-dependent antioxidant response was recorded when extracts were tested as an inhibitor of DPPH and ABTS free radicals. The results revealed that oat grains are a good source of nutrients, minerals, and phytochems. that can be used as nutraceuticals and as food. The genetic differences revealed that this plant can be grown under varied environmental conditions.

Maeda, Allyn H. published the artcileChemical and genomic analyses of polycyclic aromatic hydrocarbon biodegradation in Sphingobium barthaii KK22 reveals divergent pathways in soil sphingomonads, Product Details of C11H8O3, the publication is International Biodeterioration & Biodegradation (2020), 104993, database is CAplus.

Polycyclic aromatic hydrocarbons (PAHs) are hazardous pollutants that are biodegraded by soil bacteria and the soil sphingomonads are thought to be major contributors to PAH biodegradation To predict PAH environmental fates it is necessary to understand the chem. and genetics of PAH biodegradation by sphingomonads. When the soil sphingomonad Sphingobium barthaii KK22 was exposed to low mol. weight (LMW) PAHs and biotransformation products were investigated by comprehensive chem. analyses, at least twenty products were identified by different techniques and both intradiol- and extradiol-aromatic ring cleavage pathways were found to be active in this organism. Sphingomonads, a large and diverse group, have been studied in regard to PAH biodegradation, however intradiol-ring cleavage of LMW PAHs has never been reported. Whole genome sequencing and prediction of S. barthaii KK22 functional genes revealed sets of aromatic ring-hydroxylating oxygenases and PAH biotransformation genes. Combined with chem. analyses results, novel, near complete PAH biotransformation pathways for soil sphingomonads were constructed. In conjunction with quant. assays, a comprehensive view of PAH biodegradation was obtained that revealed divergent downstream pathways that advanced our understanding of the PAH biotransformation capabilities of these versatile soil bacteria and shall aid in predictions of PAH environmental fate during soil bioremediation.

Yang, Ling published the artcileThe pH-influenced PET processes between pyronine and different heterocycles, Related Products of alcohols-buliding-blocks, the publication is Organic & Biomolecular Chemistry (2017), 15(39), 8402-8409, database is CAplus and MEDLINE.

The OFF-ON and ON-OFF type pH probes based on rosamine were designed by using the relative electron densities between pyronine and various linked heterocycles. Probe 1a with an indole-pyronine skeleton gave an OFF-ON pH response (pK_a = 1.41) with decreasing pH, and the relative fluorescence intensity increased 15-fold, while probe 1b with an imidazole-pyronine skeleton did not give an ON-OFF response to different pH values. When pyronine was connected with a quinolinyl group, i.e., probes 1c-d, the red emission (around 575-800 nm) gave a monotonous ON-OFF pH response (pK_a = 3.26 and 2.62, resp.) with decreasing pH. The relative fluorescence intensities decreased 263- and 46-fold, resp. Changes in the electron donating abilities of the nitrogen containing heterocycles were used to explain variations in PET processes within the probes, and their pH-dependent PET mechanisms were verified using time-dependent d. functional theory calculations Confocal fluorescence imaging was also used to evaluate the potential biomedical application of probes 1a-d. Ultimately, probe 1d (I) with an appropriate pK_a value and good biocompatibility showed lysosome targeting ability.
