Study on Characteristics and Lignification Mechanism of Postharvest Banana Fruit during Chilling Injury.

The banana is prone to chilling injury (CI) at low temperature and showing a series of chilling symptoms, such as peel browning, etc. Lignification is a response to abiotic stress and senescence, which is an important manifestation of fruits and vegetables during chilling exposure. However, little is known about the lignification of bananas during low-temperature storage.

Pentalysine beta-carbonylphthalocyanine zinc: an effective tumor-targeting photosensitizer for photodynamic therapy.

Unsymmetrical phthalocyanine derivatives have been widely studied as photosensitizers for photodynamic therapy (PDT), targeting various tumor types. However, the preparation of unsymmetrical phthalocyanines is always a challenge due to the presence of many possible structural isomers. Herein we report a new unsymmetrical zinc phthalocyanine, pentalysine beta-carbonylphthalocyanine zinc (ZnPc-(Lys)(5)), that was prepared in large quantity and high purity.

[Effect of Jianpi Jiedu decoction to PTEN/ERK1 of athymic mice with hepatocellular carcinoma].

Objective: To research the effect of Jianpi Jiedu decoction (JPJDT) to PTEN/ERK1 of athymic mice with hepatocellular carcinoma.

Method: N2 male BALB/c athymic mice models were built by Bel-7402 with an indirect method. After 24 h of postoperation, the 90 athymic mice were distributed randomly into JPJDT groups: A, B, C, D, E, F, G, NS, FT each group had 10 athymic mice.
