A New Species and New Record of Freshwater Turbellarians of the Genus (Platyhelminthes: Rhabdocoela) from China.

A new species of Dalyelliidae, Wang and You, is described based on material collected in southern China through an integrative approach combining morphological, histological, and molecular (18S and 28S rDNA) data. sp. nov.

Two new species of a new genus, Pseudorogneda, of Polycystididae discovered in Southern China.

Two new species of the new genus Pseudorogneda of Polycystididae were discovered in a brackish environment from Southern China. Pseudorogneda sinensis n. gen.

Two new species of marine flatworm from southern China facilitate determination of the phylogenetic position of the genus Nerpa Marcus, 1948 and the histochemical structure of the nervous system in the genus Paucumara Sluys, 1989 (Platyhelminthes, Tricladida, Maricola).

Two new species of flatworm, collected from a beach at eastern Shenzhen, China, were studied through an integrative approach by combining morphological, histological, histochemical (acetylcholinesterase, AChE), and molecular (18S r- DNA) data. These species belong to two genera of marine triclads, previously unrecorded from China, viz. Nerpa Marcus, 1948 and Paucumara Sluys, 1989.

Kandeliimicrobium roseum gen. nov., sp. nov., a new member of the family Rhodobacteraceae isolated from mangrove rhizosphere soil.

A Gram-stain-negative, non-flagellated, short rod-shaped bacterium, designated XY-R6, was isolated from the rhizosphere soil of a mangrove plant, Kandelia candel (L.) Druce, in Mai Po Nature Reserve, Hong Kong. Growth of strain XY-R6 was observed at pH 5.

Mutation Analysis and Prenatal Exclusion of Fibrodysplasia Ossificans Progressiva in a Chinese Fetus.

Aims: Fibrodysplasia ossificans progressiva (FOP) is a rare and severely disabling autosomal dominant disorder characterized by congenital malformations of the great toes and progressive postnatal heterotopic ossification. A point mutation in the activin receptor IA (ACVR1) gene is the cause of FOP. Most of the reported cases of FOP are sporadic and caused by de novo mutations; however, some rare cases can also result from parental germline mosaicism associated with a greater risk of recurrence in successive pregnancies.

[Using MSR model to analyze the impact of gene-gene interaction with related to the genetic polymorphism of metabolism enzymes on the risk of breast cancer].

Objective: To identify the interactions of susceptive genes with related to the genetic polymorphism of metabolism enzymes (CYP1A1, GSTT1 and GSTM1) and their impacts on the risk of breast cancer; and to test the feasibility of using Multifactor Dimensionality Reduction (MDR) model in analyzing gene-gene interactions.

Methods: A paired case-control study, matched by age and menstruate state, was conducted. From December 2003 to September 2004, 78 pairs of people with and without breast cancers were investigated.

[Dental caries in children with cleft lip and/or palate in China].

Objective: To determine the prevalence of dental caries in children with cleft lip and Palate.

Methods: A cross-sectional study was undertaken in 380 children with cleft lip and Palate and 339 children without cleft. Dental caries were measured with decayed-missing-filed-teeth index (DMFT/dmft) and the decayed-missing-filed-surface index (DMFS/dmfs).

[Study on the relationship between organochlorine pesticides and level of residues in serum and daily foodstuff].

Objective: To study the contents of organochlorine pesticides in human bodies and residues in serum of populations with non-occupational exposure as well as to study the relationship between organochlorine pesticides in foodstuff and residues levels in serum.

Methods: A cross-section study was conducted. 107 men and 142 women who were all healthy and living in the communities were investigated from Mar.

[Cloning and expression analysis in mature individuals of salmon gonadotropin-releasing hormone (sGnRH) gene in common carp].

Two types of complementary DNAs (cDNA) encoding the precursor of salmon gonadotropin-releasing hormone (sGnRH, [Trp7, Leu8] GnRH) are cloned and sequenced from common carp brain using rapid amplification of cDNA ends (RACE). The two cDNAs are referred to sGnRH cDNA1 and cDNA2, and the full-length fragment of cDNA1 and cDNA2 were 393 and 478 bp, respectively. Two sGnRH cDNAs contain an open reading frame of 285 bp, which encodes the sGnRH precursor including 94 amino acid residues.
