Arguelles, Eldrin DLR. published the artcileLipid accumulation and profiling in microalgae Chlorolobion sp. (BIOTECH 4031) and Chlorella sp. (BIOTECH 4026) during nitrogen starvation for biodiesel production, HPLC of Formula: 110-42-9, the main research area is Chlorolobion Chlorella lipid accumulation nitrogen starvation biodiesel.

When the amount of nitrate was limited, the mean oil contents of Chlorolobion sp. and Chlorella sp. were 31.61 and 28.77% with lipid productivity of 227.84 and 151.14 mg L-1 day-1, resp. Nitrogen starvation caused an increase in the lipid yield and a decrease in biomass production of the two microalgae. The FAME profile of the obtained algal biodiesel shows a high concentration of saturated fatty acid (SAFA) and monounsaturated fatty acid (MUFA) Me esters which are desirable for biodiesel production The fuel properties of biodiesel from the two microalgae were predicted based on the mol. properties of fatty acid Me esters using empirical equations showing that the biodiesel properties of the two microalgae satisfied the set specifications of biodiesel standards EN 14214 (European) and ASTM D6751 (American). The quality properties of biodiesel obtained for Chlorolobion sp. were low d. (0.89 g cm-3), low kinematic viscosity (2.79 mm2 s-1), cetane number (65.17), and oxidation stability (8.93 h). On the other hand, Chlorella sp. has low d. (0.88 g cm-3), low kinematic viscosity (2.78 mm2 s-1), good cetane number (68.79), and oxidation stability (10.44 h). Hence, Chlorolobion sp. (BIOTECH 4031) and Chlorella sp. (BIOTECH 4026) have potential as raw material for production of biodiesel with superior fuel quality.

Luo, Manli published the artcileEffect of Glycine Betaine Treatment on Aroma Production of ‘Nanguo’ Pears After Long-Term Cold Storage-Possible Involvement of Ethylene Synthesis and Signal Transduction Pathways, Recommanded Product: Methyl octanoate, the main research area is glycine betaine ethylene aroma nanguo storage signal transduction pathway.

Glycine betaine (GB) treatment is considered effective in preventing low ester production in cold-stored ‘Nanguo’ pears (Pyrus ussuriensis Maxim.). Here, the mechanism of GB on ethylene biosynthesis and signal transduction to accelerate esters accumulation was investigated. We observed a higher ethylene production in GB-treated ‘Nanguo’ pears than that in controls. Genes directly related to ethylene biosynthesis (PuACO1, PuACO2, and PuACS) and ethylene response factors (PuERF2, PuERF109-like, PuERF071-like, PuERF015, PuERF114, PuRAV1-like, and PuERF113-like) were upregulated during cold storage and subsequent shelf at room temperature, and pos. contributed to biosynthesis of esters. Moreover, it was found that pears treated with GB increased the content of GB by improving the activity and expression of choline monooxygenase and betaine dehydrogenase, whereas high GB content was pos. correlated with high ethylene production Collectively, these results suggested that triggering of the biosynthesis of ethylene and signal transduction pathways may be the mechanism responsible for the conservation of esters by GB treatment.

Morales, Maria L. published the artcileTriclabendazole treatment failure for Fasciola hepatica infection among preschool and school-age children, Cusco, Peru, Product Details of C12H9N3O5S, the main research area is Fasciola hepatica triclabendazole antimicrobial chronic fascioliasis; Cusco; Fasciola hepatica; Peru; antimicrobial resistance; drug resistance; efficacy; fascioliasis; infection; liver fluke; parasites; preschool children; school-age children; treatment failure; trematode; triclabendazole.

We conducted a retrospective cohort study of children who had chronic fascioliasis in the highlands of Peru to determine triclabendazole treatment efficacy. Children passing Fasciola eggs in stool were offered directly observed triclabendazole treatment (>1 doses of 10 mg/kg). Parasitol. cure was evaluated by using microscopy of stool 1-4 mo after each treatment. A total of 146 children who had chronic fascioliasis participated in the study; 53% were female, and the mean ± SD age was 10.4 ± 3.1 years. After the first treatment, 55% of the children achieved parasitol. cure. Cure rates decreased after the second (38%), third (30%), and fourth (23%) treatments; 17 children (11.6%) did not achieve cure after 4 treatments. Higher baseline egg counts and lower socioeconomic status were associated with triclabendazole treatment failure. Decreased triclabendazole efficacy in disease-endemic communities threatens control efforts. Further research on triclabendazole resistance and new drugs to overcome it are urgently needed.

El Majdoub, Yassine Oulad published the artcileChemical characterization of three accessions of Brassica juncea L. extracts from different plant tissues, Application In Synthesis of 111-11-5, the main research area is chem composition root stem leaf Brassica; Brassica juncea spp.; GC; HPLC; foods; metabolites; non-volatile; nutraceuticals; volatile.

Indian mustard or Brassica juncea (B. juncea) is an oilseed plant used in many types of food (as mustard or IV range salad). It also has non-food uses (e.g., as green manure), and is a good model for phytoremediation of metals and pesticides. In recent years, it gained special attention due to its biol. compounds and potential beneficial effects on human health. In this study, different tissues, namely leaves, stems, roots, and flowers of three accessions of B. juncea: ISCI 99 (Sample A), ISCI Top (Sample B), and “”Broad-leaf”” (Sample C) were analyzed by HPLC-PDA/ESI-MS/MS. Most polyphenols identified were bound to sugars and phenolic acids. Among the three cultivars, Sample A flowers turned were the richest ones, and the most abundant bioactive identified was represented by Isorhamnetin 3,7-diglucoside (683.62 μg/100 mg dry weight (DW) in Sample A, 433.65 μg/100 mg DW in Sample B, and 644.43 μg/100 mg DW in Sample C). In addition, the most complex samples, viz. leaves were analyzed by GC-FID/MS. The major volatile constituents of B. juncea L. leaves extract in the three cultivars were benzenepropanenitrile (34.94% in Sample B, 8.16% in Sample A, 6.24% in Sample C), followed by benzofuranone (8.54% in Sample A, 6.32% in Sample C, 3.64% in Sample B), and phytone (3.77% in Sample B, 2.85% in Sample A, 1.01% in Sample C). The overall evaluation of different tissues from three B. juncea accessions, through chem. anal. of the volatile and non-volatile compounds, can be advantageously taken into consideration for future use as dietary supplements and nutraceuticals in food matrixes.

Huang, Yaling published the artcileVariation of Volatile Compounds and Corresponding Aroma Profiles in Chinese Steamed Bread by Various Yeast Species Fermented at Different Times, Application of Benzyl acetate, the main research area is volatile aroma Chinese steamed bread yeast; Chinese steamed bread; GC−MS; GC−O; aroma-active compounds; sensory evaluation.

To control the fermentation process of yeast-Chinese steamed bread (CSB), the volatile compounds and odor profiles of yeast-CSBs during fermentation were comprehensively investigated by sensory evaluation, gas chromatog.-mass spectrometry, gas chromatog.-olfactometry (GC-O), and odor activity value (OAV). Eight sensory attributes were established, and quant. descriptive anal. results showed that CF1303-CSB had intense sweet and sweet aftertaste attributes, CF1318-CSB was characterized by milky, wheaty, and yeasty attributes, while CL10138-CSB presented distinct sour, winy, and floury attributes. A total of 41 key aroma-active compounds were detected, and phenylethyl alc. was the most potent aroma compound with a flavor dilution (FD) of 1024. CF1303-CSB, CF1318-CSB, and CL10138-CSB contained 24, 22, and 21 key aroma compounds, resp., based on the OAV. These key aroma compounds can be used as the potential markers to monitor the yeast-CSBs during the fermentation process. Five compounds, including β-myrcene, 2-phenoxyethanol, Me cinnamate, guaiacol, and o-cresol, were first identified in CSB. These results provide theor. basis for processing and quality control of yeast-CSBs.
