Characteristics of protein variants in trichlorphon-resistant Bactrocera dorsalis (Diptera; Tephritidae) larvae

Authors: T. Jin, L. Zeng, Y.-Y. Lin, Y.-Y. Lu and G.-W. Liang

Functional proteins in larvae of Bactrocera dorsalis, a major fruit pest, play a central role in their resistance to organophosphorus insecticides. Changes in proteins in B. dorsalis larvae after trichlorphon treatment may have a role in the resistance response to trichlorphon. We analyzed 14 protein spots of crude proteins from B. dorsalis larvae post-tr.. Read More»

Weak cation magnetic separation technology and MALDI-TOF-MS in screening serum protein markers in primary type I osteoporosis

Authors: X.L. Shi, C.W. Li, B.C. Liang, K.H. He and X.Y. Li

We investigated weak cation magnetic separation technology and matrix-assisted laser desorption ionization-time of flight-mass spectrometry (MALDI-TOF-MS) in screening serum protein markers of primary type I osteoporosis. We selected 16 postmenopausal women with osteoporosis and nine postmenopausal women as controls to find a .. Read More»

Correlation between mandibular gland secretion and cuticular hydrocarbons in them stingless bee Melipona quadrifasciata

Authors: C. Cruz-Landim, M.J. Ferreira-Caliman, L.F. Gracioli-Vitti and R. Zucchi

We investigated whether Melipona quadrifasciata worker mandibular gland secretions contribute directly to their cuticular hydrocarbon profile. The mandibular gland secretion composition and cuticular surface compounds of newly emerged worker bees, nurse bees, and foragers were determined by gas chromatography and mass spectrom.. Read More»

Serum proteomic spectral characteristics of acute myeloid leukemia and their clinical significance

Authors: R.-J. Zheng, R.-J. Wu and X.-D. Ma

We investigated the differences between the serum proteomic spectral characteristics of acute myeloid leukemia (AML) patients and those of healthy people. We collected peripheral blood serum samples from 62 AML patients and 15 healthy controls. After removing high-abundance proteins, low-abundance serum proteins were separated.. Read More»

Identification of a Panax ginseng fruit fingerprint by HPLC-ESI-MS

Authors: H.F. Zhao1, F.F. Xu2, Y.T. Guo1 and H. Mi1

Over many years, parts of Panax ginseng (root and rhizome) have been identified and applied for medical purposes as traditional Chinese herbal medicine. Recently, research has indicated that ginseng fruit also contains similar compounds and is as rich as the other parts of the ginseng. This discovery may dramatically improve the efficient of outputs deriv.. Read More»

Proteomic analysis of mycelial proteins from Magnaporthe oryzae under nitrogen starvation

Authors: X.-G. Zhou, P. Yu, C. Dong, C.-X. Yao, Y.-M. Ding, N. Tao andZ.-W. Zhao

Magnaporthe oryzae is an important model system in studies of plant pathogenic fungi, and nitrogen is a key nutrient source affecting microbial growth and development. In order to understand how nitrogen stress causes changes in mycelial proteins, we analyzed differentially expressed mycelial proteins from the M. oryzae virule.. Read More»
