Abstract

The study investigated the effects of additives (molasses, seaweed, and fishmeal) on compost tea's nutrient content and fermentation characteristics. Compost tea contains a lot of nutrients and can be used as a supplement for soil nutrients. Molasses, seaweed and fishmeal are common additives in compost tea, and their effects on nutrients in compost tea are the purpose of this study. In this paper, to study the compost tea with added nutrients molasses, seaweed, and fishmeal compost tea, the effects of pH, organic matter, total nitrogen, ammonium nitrogen, nitrate nitrogen and bacteria on the fermentation characteristics of compost tea were investigated with different ratios (1 : 5, 1 : 6, 1 : 7, 1 : 8, 1 : 9) of fertilizer to water. The results showed with the increase of extraction ratio, molasses decreased pH value and ammonium nitrogen content, and seaweed and fishmeal promoted nitrogen mineralization. The optimal fermentation ratio was 1:5 for compost tea.

Abstract

Annealing control primer (ACP) system was applied to find candidate genes related to lipidosis in muscle of Yanbian yellow cattle by screening differentially expressed genes (DEGs) in Longissimus dorsi, which had significant difference on intramuscular fat (IMF) content. Thirty steers, aged at 28 month-bullocks were selected to measure the IMF content in L. dorsi. Two groups of bullocks (three heads per group) with the highest and the lowest contents of IMF were selected to build a RNA pool, and DEGs of two groups were analyzed by ACP system. Twelve DEGs were identified and sequenced by amplification with 20 arbitrary primers (fragment sizes were 200-890 bp). In these genes, eight were already known as functional groups of cytoskeleton, cytokine signal transduction, protein synthesis, energy metabolism, and others, four were unknown. All the 12 ESTs were screened by ACP system, which may participated in regulating on lipidosis in muscle. This study established a foundation for further screening of lipidosis related genes.

Abstract

The Caosiyao giant porphyry Mo deposit (1.76 Mt), which is the third largest such deposit in China, is located on the northern margin of the North China Craton and associated with the Caosiyao intrusive complex that was emplaced in Archaean metamorphic rocks. The intrusive complex consists of monzogranite and coarse‐, medium‐, and fine‐grained granite porphyries that yield U―Pb ages of 148.5 ± 1.2, 146.4 ± 1.0, 144.6 ± 1.0, and 142.8 ± 3.2 Ma, respectively. Four molybdenite Re―Os model ages range from 143.1 ± 2.4 to 145.3 ± 2.1 Ma, which are consistent with the U―Pb ages for the igneous complex. The geochronological data indicate that the multistage magmatic‐hydrothermal processes were important in the formation of the Caosiyao giant deposit. The rocks of the Caosiyao granitic complex have high contents of silica (SiO2 = 71.7–75.6 wt.%) and total alkalis (mostly K2O + Na2O > 8 wt.%), low contents of CaO and MgO, and exhibit peraluminous high‐K calc‐alkaline to shoshonitic affinities. They are enriched in large‐ion lithophile elements (e.g., K, Rb, U, and Th) and light REEs and depleted in Eu, Ba, Sr, Nb, P, and Ti. The geochemical characteristics indicate advanced fractional crystallization and that the rocks are strongly fractionated I‐type granites. The negative Hf isotopic compositions of the granitic rocks, combined with old two‐stage Hf model ages, indicate the magmas were derived from partial melting of the ancient lower crust of the North China Craton. All the intrusive rocks in the complex have relatively high Ce4+/Ce3+ ratios and oxygen fugacity, which would have facilitated Mo extraction into the melts owing to the much higher solubility of S as sulphate (SO42−) than sulphide (S2−). The magma crystallization temperatures decreased from 882°C to 770°C as the magma evolved. The multistage magmatic‐hydrothermal processes, and the prolonged fractional crystallization, combined with high magma oxygen fugacity are the key factors to form the Caosiyao giant Mo deposit. The tectonic setting of deposit formation was one of extension related to rollback of the subducting Palaeo‐Pacific Plate during the Late Jurassic to Early Cretaceous. [ABSTRACT FROM AUTHOR]

Abstract

Background/Aims: How to select a suitable method in whitening products evaluation is still under discussion. Here, we compared two different artificial pigmentation models and explored an ideal UV dosage for skin whitening products evaluation model establishment. Methods: Thirty five healthy volunteers with type IV human skin were recruited and the skin minimal erythema dose (MEDs) and minimal persistent pigment dose (MPPDs) were measured. All volunteers were simultaneously exposed to six increasing doses of radiations from different ultraviolet sources on lower back bilateral flattening area: 95% UVA/5% UVB with the radiating doses of 0.75, 0.94, 1.17, 1.46, 1.83, 2.29 MEDs was used on the left side; meanwhile 99% UVA/1% UVB with radiating doses of 6.0, 7.5, 9.4, 11.7, 14.6, 18.3 MPPDs were used on the right side. Observations and pigmentation measurements were carried out before and after UV radiation for 24 weeks. Result: 1.83 MED and 2.29 MED induced medium depth pigmentation by 95% UVA/5% UVB irradiation. 1.83 MED dose causing minimal photo‐damage on skin was selected as the most suitable dose. With 99% UVA/1% UVB irradiation, 9.4 MPPD and 11.7 MPPD induced medium depth pigmentation. 9.4 MPPD dose causing minimal photo‐damage on skin was selected. Conclusion: These findings potentiate advanced understanding of UV model establishment and selection for skin whitening products evaluation as related to dermatopharmacology and dermatotoxicology.
