Laparoscopic radical antegrade modular pancreatosplenectomy: preliminary experience with 10 cases.

Background: The radical antegrade modular pancreatosplenectomy (RAMPS) which is a reasonable surgical approach for left-sided pancreatic cancer is emphasis on the complete resection of regional lymph nodes and tumor-free margin resection. Laparoscopic radical antegrade modular pancreatosplenectomy (LRAMPS) has been rarely performed, with only 49 cases indexed on PubMed. In this study, we present our experience of LRAMPS.

Identification of QTLs associated with curd architecture in cauliflower.

Background: Curd architecture is one of the most important characters determining the curd morphology of cauliflower. However, the genetic mechanism dissection of this complex trait at molecular level is lacking. Genes/QTLs responsible for the morphological differences between present-day loose-curd and compact-curd cauliflower haven't been well revealed.

Genome wide analysis of MADS-box gene family in Brassica oleracea reveals conservation and variation in flower development.

Background: MADS-box genes play important roles in vegetative growth and reproductive development and are essential for the correct development of plants (particularly inflorescences, flowers, and fruits). However, this gene family has not been identified nor their functions analyzed in Brassica oleracea.

Results: In this study, we performed a whole-genome survey of the complete set of MADS-box genes in B.

Rapid determination of neomycin in biological samples using fluorescent sensor based on quantum dots with doubly selective binding sites.

A new analytical method was developed to detect neomycin in complex biological samples using molecularly imprinted polymer to construct an optical sensor. Fluorescent neomycin-imprinted polymers (fMIPs) containing both imprinted cavity and boronate affinity site were synthesized on the surface of silica-modified quantum dots. The fMIPs exhibited high selectivity to neomycin by having two binding sites for the target analyte.

Continuous surveillance of organochlorine pesticides in human milk from 1983 to 1998 in Beijing, China.

A study was carried out to study the accumulative levels and dynamic changes of organochlorine pesticides in human milk in Beijing from 1982 to 1998, and the effect of prohibition and restriction on the use of DDT and BHC (666) in China in 1983. The milk samples were collected from women during the lactation period in four districts of Beijing from 1982 to 1998, in 1991, 1993 and 1998, respectively. The contents of DDT and BHC in human milk were determined according to the standard method of biology-monitoring of PR China.

[The investigation on basic contents of organochlorine pesticides in human milk during consecutive periods in Beijing urban areas].

Objective: To investigate the basic contents of organochlorine pesticides (DDT, BHC and HCB) in human milk of normal residents in Beijing urban areas.

Methods: Through continuous survey on the trend of organochlorine contents in human milk since DDT and BHC pesticides were forbidden in use in 1983, and to evaluate the effects of this program, the required lying-in women residents in urban districts for at least 5 years were enrolled in this study. All these lying-in women and also their family members were not exposed to or engaged in producing or selling organochlorine pesticides.
