Yang, Zhi published the artcileEffects of dietary vitamin E supplementation levels on growth performance, breast muscle meat quality characteristics, and fatty acid composition of geese, Recommanded Product: Docosahexaenoic Acid, the publication is Journal of Food Science (2022), 87(8), 3396-3406, database is CAplus and MEDLINE.

This study investigated the effects of dietary supplementation with vitamin E (VE) on the growth performance, breast muscle quality, fatty acid (FA) composition, and muscle fiber characteristics of geese. In the present study, a total of 240 healthy 29-day-old male Jiangnan white geese were randomly divided into six exptl. groups, with five replicates in each group and eight geese in each replicate. Group A, the control group, was fed a basal diet; Groups B, C, D, E, and F were fed diets supplemented with 5, 10, 20, 40, and 80 mg/kg VE. After feeding for 70 days of age, one gosling from each replicate was randomly selected and slaughtered to assess the breast muscle quality characteristics, lipid oxidation, FA composition, and muscle fiber characteristics. The results showed that dietary VE supplementation did not significantly affect the growth performance, breast muscle quality characteristics, or muscle fiber characteristics of geese (p > 0.05). Dietary supplementation with 20, 40, and 80 mg/kg VE significantly decreased the malondialdehyde (MDA) content of the breast muscle compared with the control group (P < 0.05). Dietary supplementation with 40 and 80 mg/kg VE significantly increased the retention of ¦Á-tocopherol in pectoral muscle, decreased polyunsaturated fatty acid (PUFA) oxidation, and increased the proportion of n-3 PUFAs (p < 0.05). In conclusion, dietary supplementation with 5-80 mg/kg VE to the basal diet (VE content of the basal diet: 17.53 mg/kg) had no significant effect on the growth performance of geese. However, dietary supplementation with 40-80 mg VE increased the retention of ¦Á-tocopherol in breast muscle tissue, reduced the oxidation of PUFAs, and increased the content of n-3 PUFAs. Thus, under these exptl. conditions, dietary supplementation with 40-80 mg/kg VE is recommended, which is beneficial to human health. Appropriate supplementation of VE could increase meat quality and the beneficial components in breast muscle of geese. It provides a theor. basis for future production of high-quality goose meat.

Li, Jie published the artcileEmission characteristics and assessment of potential health risks on PM_2.5-bound organics from incense burning, Safety of Coronene, the publication is Atmospheric Pollution Research (2022), 13(3), 101326, database is CAplus.

Incense burning is a nonnegligible indoor air pollution source in many Asian countries, particularly in China. There is a lack of regulation on the formations of incense and its emissions. Herein, the emission factors (EFs) of important particulate phase toxic compounds, parent polycyclic aromatic hydrocarbons (pPAHs), alkylated PAHs (APAHs), oxygenated PAHs (OPAHs), nitro PAHs (NPAHs), and cyclohexanes were determined from the burning of the most representative types of Chinese incenses (i.e., five Nimu Tibetan incenses [NTI], one ordinary smoke incense [SI], and one smoke-free incense [SFI]). The total EFs of the quantified organic species (EF_¦²organics) for NTI was 7.44 ¡À 2.72 ¦Ìg g^-1 on average, within the levels of SI to SFI. The pPAHs showed the largest proportion (41.5%-63.7%) of the total quantified organics The total cancer risks for all examined incenses severely exceeded the health risk threshold value of 1 x 10^-4, verifying that incense burning poses certain extent damage to human health. Notably, the organic compositions of NTI and SFI burnings were similar, with lower EFs and inhalation lifetime cancer risks than SI. The present results suggest that the advanced types of incenses of NTI or SFI should be better choices than SI while the incense burning is necessary. This acts as a guide for the residents, visitors, and workers in the selections of incenses that offer lower toxic substances emissions in dwellings or temples. In addition, the high health risks for incense emissions alert the establishment of more restrictive regulations on incense production and emission are compulsory.

Huang, Wen-Ching published the artcileEffects of exercise on high-fat diet-induced non-alcoholic fatty liver disease and lipid metabolism in ApoE knockout mice, Recommanded Product: Docosahexaenoic Acid, the publication is Nutrition & Metabolism (2022), 19(1), 10, database is CAplus and MEDLINE.

Non-alc. fatty liver disease (NAFLD), which is growing more common in the Western world, has become the main cause of chronic liver disease and is strongly associated with metabolism syndromes. NAFLD can indicate a wide spectrum of hepatic pathologies, ranging from simple hepatic steatosis and inflammatory non-alc. steatohepatitis to more severe stages of fibrosis and cirrhosis. Moreover, evidence has demonstrated that phys. inactivity and westernized dietary habits may facilitate the development of NAFLD. Lipid modulation and metabolism could be important factors in the development of steatosis. Lipid species, characterized using a lipidomic approach with untargeted anal., could provide potential biomarkers for the pathogenesis of NAFLD or therapeutic applications. Thus, in this study, the effects of exercise on the improvement of NAFLD were further investigated from a lipidomic perspective through the aspects of lipid regulation and metabolism Wild type (WT) C57BL/6 J and C57BL/6-ApoEem1Narl/Narl mice were assigned to one of four groups: WT mice fed a normal chow diet (CD), apolipoprotein E (ApoE) knockout mice fed a normal CD, ApoE knockout mice fed a high-fat diet (HFD), and ApoE knockout mice fed a HFD and provided with swimming exercise. The treatments (e.g., normal diet, HFD, and exercise) were provided for 12 consecutive weeks before the growth curves, biochem., fat composition, pathol. syndromes, and lipid profiles were determined Exercise significantly reduced the HFD-induced obesity (weight and fat composition), adipocyte hypertrophy, liver lipid accumulation, and pathol. steatosis. In addition, exercise ameliorated HFD-induced steatosis in the process of NAFLD. The lipidomic anal. revealed that the changes in plasma triglyceride (14:0/16:0/22:2), phosphatidic acid (18:0/17:2), and phosphatidylglycerol (16:0/20:2) induced by the administration of the HFD could be reversed significantly by exercise. The 12-wk regular exercise intervention significantly alleviated HFD-induced NAFLD through modulation of specific lipid species in plasma. This finding could elucidate the lipids effects behind the hepatic pathogenesis with exercise.

Zhang, Jianxin published the artcileRedox and pH dual-stimuli responsive wormlike micelles based on CTAB and sodium dithiodibenzoate, Synthetic Route of 119-80-2, the publication is Journal of Dispersion Science and Technology, database is CAplus.

Stimulus-responsive wormlike micelles (WLMs) have attracted much attention in the past decade. In this work, dual-stimuli (pH and redox reaction) responsive WLMs were prepared with sodium 2,2¡ä-dithiodibenzoate (DTSA) and cetyltrimethylammonium bromide (CTAB). The WLMs can be reversibly switched on and off by an alternating redox reaction originating from the cleavage and reformation of the disulfide bonds in DTSA. Moreover, the WLMs can also respond to pH stimulus. The corresponding responsive behaviors of WLMs were revealed using rheometer, cryogenic transmission electron microscopy, and ¹H NMR analyses. The multi-stimuli responsive behavior makes the current system a good candidate for smart control of the sol-gel transition.

Huang, Meng-meng published the artcileIdentification of six novel microalgal strains and characterization of its potential for development of high-value compounds, Synthetic Route of 6217-54-5, the publication is South African Journal of Botany (2022), 1-7, database is CAplus.

In this study, six microalgae strains were isolated from samples collected in alpine regions, identified by 18S rRNA and rbcL gene sequencing, and assessed for their ability to produce biodiesel and high-value compounds The six strains were isolated from three alpine regions (Daqing, Zhaodong and Zhalong Salt Lake). Phylogenetic neighbor-joining anal. indicated that the strains designated as HDA01, HDA04, and HDA07 belong to the genus Chlorella sp., HDA03 to the genus Scenedesmus sp., HDA05 to the genus Micractinium sp., and HDA06 to the genus Desmodesmus sp. Biomass productivity, lipid yield, fatty acid profiles and other indexes were evaluated to assess whether these strains have potential applications. Chlorella sp. HDA04 has potential as a biodiesel producer, based on its high biomass productivity (3.95¡À0.05 gL-1), high lipid productivity (472.99¡À18.97 mg L-1d-1), and its fatty acid profiles which meets European standards for biodiesel. HDA07 accumulates a high ¦Á-linolenic acid (ALA) content (26.12% of total lipids), which makes this strain potentially suitable for production of this high-value product.

Hu, Kuan published the artcileWhole-body PET tracking of a D-dodecapeptide and its radiotheranostic potential for PD-L1 overexpressing tumors, SDS of cas: 71989-31-6, the publication is Acta Pharmaceutica Sinica B (2022), 12(3), 1363-1376, database is CAplus and MEDLINE.

Peptides that are composed of dextrorotary (D)-amino acids have gained increasing attention as a potential therapeutic class. However, our understanding of the in vivo fate of D-peptides is limited. This highlights the need for whole-body, quant. tracking of D-peptides to better understand how they interact with the living body. Here, we used mouse models to track the movement of a programmed death-ligand 1 (PD-L1)-targeting D-dodecapeptide antagonist (DPA) using positron emission tomog. (PET). More specifically, we profiled the metabolic routes of [⁶⁴Cu]DPA and investigated the tumor engagement of [⁶⁴Cu/⁶⁸Ga]DPA in mouse models. Our results revealed that intact [⁶⁴Cu/⁶⁸Ga]DPA was primarily eliminated by the kidneys and had a notable accumulation in tumors. Moreover, a single dose of [⁶⁴Cu]DPA effectively delayed tumor growth and improved the survival of mice. Collectively, these results not only deepen our knowledge of the in vivo fate of D-peptides, but also underscore the utility of D-peptides as radiopharmaceuticals.

Liu, Xianhu published the artcileQuantum-size-effect accommodation of gold clusters with altered fluorescence of dyes, Application of 5,9-Diaminobenzo[a]phenoxazin-7-ium acetate, the publication is RSC Advances (2015), 5(39), 30610-30616, database is CAplus.

We have synthesized monodispersed Au₂₅ nanoclusters (NCs) stabilized with eco-friendly glutathione and report here an insight into their interactions with dye mols. In the presence of such gold NCs, consistent fluorescence quenching was observed for all the dye mols. that we examined in this study regardless of their maximum emission wavelengths. The steady-state and time-resolved spectroscopic results demonstrate that the weakened luminance is associated with the protective ligand pertaining to a static quenching mechanism. Having expounded this issue, we further employed proper laser irradiation enabling dissociation of Au₂₅(SG)₁₈ so as to attain a transformation of nonplasmonic NCs into plasmonic gold nanoparticles (NPs) via photo-assisted aggregation of the dissociated gold clusters. As a result, emission enhancement for these dyes was observed, which is largely attributed to the local electromagnetic field enhancement of gold NPs. The alternation of fluorescence quenching to emission enhancement reflects an accommodation of quantum size effects upon the ligand-stabilized gold clusters.

Shen, Shi-Ke published the artcileMonitoring the lipid oxidation and flavor of Russian sturgeon fillets treated with low temperature vacuum heating: formation and relationship, Formula: C22H32O2, the publication is Journal of the Science of Food and Agriculture (2022), 102(11), 4609-4619, database is CAplus and MEDLINE.

Sturgeon is one of the most precious fish resources worldwide. Low temperature vacuum heating (LTVH) has been confirmed as a good way of maintaining food quality. However, there is a lack of in-depth studies assessing the impact of LTVH on lipid oxidation and flavor formation. The present study compared the effect of LTVH and traditional cooking on lipid oxidation and flavor of sturgeon fillets. In total, 13 fatty acids were detected, of which polyunsaturated fatty acids content was the highest (P < 0.05). LTVH prevented the formation of conjugated diene and thiobarbituric acid reactive substances (P < 0.05), as manifested by an increased signal intensity of free radicals of ESR. The characteristic peaks intensity of lipid by Raman at 970 cm-1, 1080 cm-1 and 1655 cm-1 were reduced, whereas peaks at 1068 cm-1 and 1125 cm-1 displayed the opposite trend. Confocal fluorescence microscopy showed that the lipids particles were reduced and distributed more evenly with an increase in heating temperature Principal component anal. of electronic nose cannot effectively sep. all groups; however, gas chromatog.-ion migration spectrometry showed that the volatile flavor compounds were relatively stable during LTVH. Correlation anal. of all the above lipid oxidation indexes and characteristic flavor substances showed that each treatment group was located in different quadrants and demonstrated great differentiation. Overall, the results of the present study support the view that LTVH is a healthier way of cooking.

Qu, Le-tian published the artcileEffects of salinity treatment on muscle quality and off-flavour compounds of grass carp (Ctenopharyngodon idella) and black carp (Mylopharyngodon piceus), Name: Docosahexaenoic Acid, the publication is Aquaculture Research (2022), 53(13), 4823-4831, database is CAplus.

To investigate the effects of short-term salinity treatment on muscle quality and earthy and musty off-flavor compounds of freshwater fish, adult grass carp (1.25 ¡À 0.25 kg) and black carp (1.50 ¡À 0.30 kg) were reared at water salinities of 0%, 5% and 7.5%for 48 h. Muscle nutrients, amino acid, and fatty acid contents, texture properties, and earthy and musty off-flavor compounds were then determined The content of total amino acid (TAA), Lys, Arg and essential amino acid index (EAAI) in the muscle of C7.5 group were elevated significantly compared with that in the control group (p < 0.05). The content of delicious amino acids (DAA) and EAAI in the muscle of M7.5 group was significantly higher than M0 and M5 groups (p < 0.05). The fatty acid content of the muscle was affected by salinity. In grass carp, the saturated fatty acid (SFA) content level was decreased significantly in the C5 and C7.5 groups (p < 0.05), while the monounsaturated fatty acid (MUFA) and polyunsaturated fatty acid (PUFA) content levels were increased significantly in the C5 and C7.5 groups (p < 0.05). The ratio of n3/n6 PUFA increased significantly in the C7.5 group (p < 0.05). The PUFA content and the n3/n6 PUFA ratio were increased significantly in the M7.5 group (p < 0.05). With increasing salinity, the relative content levels of volatile compounds causing earthy and musty off-flavor in muscle were decreased significantly in 5% and 7.5% salinity groups both grass carp and black carp (p < 0.05). The textural properties of muscle, such as hardness, springiness, gumminess and chewiness, were improved in the C7.5 and M5 groups. These results suggest that a short-term salinity treatment in freshwater fish prior to selling can effectively improve muscle quality and decrease the content of earthy and musty off-flavor compounds, with ideal salinities of 5% or 7.5% for grass carp and 7.5% for black carp.
