[Comparison of early clinical effects between Activ C cervical disc replacement and anterior cervical discectomy and fusion for single-level cervical spondylosis].

Objective: To compare the early clinical effects of Activ C cervical disc replacement (ACDR) and anterior cervical discectomy and fusion (ACDF) in treating single-level cervical spondylosis.

Methods: The clinical data of 76 patients with single-level cervical spondylosis underwent surgery from July 2009 to September 2012 were retrospectively analyzed. Among them, 28 patients were treated with ACDR (ACDR group), including 18 males and 10 females, aged from 32 to 62 years old with an average of (45.

Cloning the sterol carrier protein 2 genes of Japanese toad (Bufo japonicus formosus) and Chinese toad (Bufo gargarizans) and its tissue expression analysis.

In this study, to clarify the bioactive polypeptides included in the skins and secretions of Bufo, we screened the Japanese toad (Bufo japonicus formosus) skin cDNA liary by colony polymerase chain reaction (PCR), and obtained a transcript of 1 075 bp consisting of 1 37 bp 5' untranslated region (UTR), 515 bp 3' UTR and a 423 bp open reading frame (ORF) encoding a polypeptide of 140 amino acid residues (GenBank accession number: KF359945). Homolog analysis showed a 70%-96% homology with sterol carrier protein-2 (SCP-2) present in other animals, which is implicated in lipid metabolism of other organisms. The gene SCP-2 of Chinese toad (B.

[Bufo gargarizans mcl-1 cloning and its prokaryotic recombinant protein expression].

MCL-1 is encoded by myeloid cell leukemia-1 gene (mcl-1), which is one of the anti-apoptotic members of bcl-2 cell apoptotic gene superfamily. ChanSu is made of dorsal secretions of several Bufo species, commonly used in the prescriptions of traditional Chinese medicine for treating many diseases including cancer. To clarify if mcl-1 is expressed in the dorsal skin of B.

[Cloning and bioinformatic analysis of TAGLN2 cDNA of Bufo japonicus formosus].

To study the bioactive polypeptides included in Bufo skin and its secretions the plasmid skin cDNA library of adult Japanese toad Bufo japonicus formosus was prepared. The pSD64TR has been used as the vector and the cloning sites are Xho I and EcoR I. To screen cDNAs encoding bioactive components, the plasmid cDNA library was transformed into E.

Stage-specific appearance of cytoplasmic microtubules around the surviving nuclei during the third prezygotic division of Paramecium.

There are six micronuclear divisions during conjugation of Paramecium caudatum: three prezygotic and three postzygotic divisions. Four haploid nuclei are formed during the first two meiotic prezygotic divisions. Usually only one meiotic product is located in the paroral cone (PC) region at the completion of meiosis, which survives and divides mitotically to complete the third prezygotic division to yield a stationary and a migratory pronucleus.

New details indicated by different stainings during conjugation of ciliated protozoa Paramecium.

During conjugation of Paramecium caudatum, nuclear events occur in a scheduled program. Morphological studies on nuclear behavior during conjugation of P. caudatum have been performed since the end of the 19th century.

Localization of stationary pronuclei during conjugation of Paramecium as indicated by immunofluorescence staining.

After the third prezygotic division during conjugation of Paramecium caudatum, migratory and stationary pronuclei are produced. The migratory pronuclei remain in the paroral region tightly against the conjugating boundaries; while the stationary pronuclei are located beside the migratory pronuclei. To date, however, it is not clear what causes this close side-by-side localization between migratory and stationary pronuclei.

[Analysis of volatile oil in Fructus Aurantii processed with Zhangband method by GC-MS].

Objective: To analyze the chemical components of the volatile oil in processed pieces of Fructus Aurantii (PPFA) with JiangXi Zhangband methods by GC-MS.

Methods: The volatile oil was obtained from PPFA by steam distillation. The amount of the components from the volatile oil were determinated by area normalization method.
