Abstract

Egg yolk is an important food ingredient because of its outstanding nutritional value and emulsifying properties. The insoluble particle structure present in egg yolk and heat treatment during food processing may lead to poor stability of egg yolk emulsion. Hydrolysis, as a safe, efficient and low-energy modification method, has been widely used in studies on improving the emulsifying properties of egg yolk. In this paper, the effects of hydrolysis on the molecular structure, physicochemical properties and emulsifying characteristics of egg yolk are reviewed. Taking into account the actual needs of production, the formation mechanism and removal process of off-flavor in egg yolk hydrolysis products are discussed. Finally, this review summarizes the application of the emulsifying properties of egg yolk in the field of food processing, with a view to providing theoretical references for research on the hydrolytic modification of egg yolk.

Abstract

A new cyclohexenone derivative, phomopine (1), together with five known compounds (2-6) were isolated from Phomopsis sp. XM-01. The structure of 1 was determined by extensive spectroscopic analyses and electronic circular dichroism (ECD) calculation. In vitro bioassays, compounds 1 and 2 exhibited potent antimicrobial activities against Candida albicans and Staphylococcus aureus with their corresponding minimum inhibitory concentrations (MICs) of 64 μg/mL and 16 μg/mL, respectively.

Abstract

A new cyclopentenone derivative, atrovinol (1), together with ten known compounds (2-11) were isolated from Trichoderma atroviride HH-01, an endophytic fungus from Illigera rhodantha (Hernandiaceae). Their structures were identified by HRESIMS, 1 D/2D NMR, and electronic circular dichroism (ECD) spectra. Compound 1 exhibited moderate inhibitory activity against Staphylococcus aureus and Bacillus subtilis with MIC values of 8.0 µg/mL and 16.0 µg/mL, respectively. [ABSTRACT FROM AUTHOR]

34. Self-assembly of porous g-C3N4 and montmorillonite: characterization, performance test, and mechanism analysis.

Abstract

Montmorillonite is successfully attached to the surface of porous graphitic carbon nitride by electrostatic self-assembly method, so that the composite photocatalyst has larger specific surface area and rich pore structure. Through a series of characterization methods such as surface area measurement (BET), photoluminescence spectra, and UV–vis diffuse reflection spectroscopy, it is confirmed that the introduction of montmorillonite is conducive to the separation of photogenerated carriers and holes in graphitic carbon nitride. The photocatalytic degradation of 20 ppm rhodamine B by composite materials only takes 90 min, and it shows the ability to degrade high concentration rhodamine B. After four cycles of regeneration, the degradation rate of rhodamine B by composite materials is still 95.4%. After the combination of porous graphitic carbon nitride and montmorillonite with electrostatic self-assembly, it has the ability to degradation of high concentration dyes, which provides a development idea for the practical application of photocatalytic technology in the field of dye degradation.

45. Secondary Metabolites from Annulohypoxylonsp. and Structural Revision of Emericellins A and B

Author

Gan, Dong, Wang, Cheng-Yao, Li, Chen-Zhe, Zhu, Li, Zhang, Xiao-Ran, Ding, Hao, Cai, Le, and Ding, ZhongTao

Abstract

Seven previously undescribed compounds were isolated from the endophytic fungus Annulohypoxylonsp. KYG-19 (family Xylariaceae), including three gymnomitrane-type sesquiterpenes xylariacinols A, B, and D (1, 2, and 4), one bisabolane-type sesquiterpene annulnol F (6), one phenol derivative lariacinol G (7), and two polyhydroxy compounds hypoxylonols H and I (8and 9), together with two known gymnomitrane-type sesquiterpenes emericellin A (3) and 3-gymnomitren-15-ol (5). The assignments of their structures was determined by extensive spectroscopic and spectrometric analysis, acetonide analysis, Mosher’s method, and X-ray crystallography. In addition, the structures of emericellins A and B, which were reported to possess an unprecedented tricyclo[4, 4, 2, 1]hendecane scaffold, were revised by comparing their spectroscopic data with those of 1and 3. Compounds 1and 4exhibited antibacterial activity against Escherichia coliwith minimum inhibitory concentrations of 4 and 2 μg/mL, respectively.

Abstract

Gonad damage is one of the major complications of chemotherapy, radiotherapy or surgery in male cancer patients. For those who wish for childbearing after treatment, it is of great significance how to protect the reproductive function of the cancer patients. The main strategy for fertility protection is to optimize the treatment protocol, hormone therapy, antioxidant therapy, and the preservation of sperm and testicular tissue. This article presents an overview on the pathogenesis of gonadal damage induced by different treatments and protection of the reproductive function of the patient.男性恶性肿瘤的放疗、化疗与手术等治疗中，主要的并发症之一是对性腺造成的损伤。对于日后有生育意愿的男性恶性肿瘤患者，如何在治疗中保护生育功能意义重大。其中优化治疗方案、激素及抗氧化治疗和精子及睾丸组织保存为主要的保护方法。本文就男性恶性肿瘤患者不同治疗造成的性腺损伤机制及生殖功能的保护方法进行综述。.
