The yield of exopolysaccharide (EPS) produced by Streptococcus thermophilus 05-34 reached up to 250 mg/L under the optimal fermentation condition, which was 4.2-fold higher than that produced under the non-optimal fermentation condition. Structure analysis showed that EPS produced under the optimal fermentation condition was composed of galactose and(More)
Heat-shock proteins (Hsp's) are a family of molecular chaperones that contribute to protection from environmental stress. In this report, we demonstrate that a member of this family, Hsp70, facilitates nuclear import of HIV-1 preintegration complexes (PICs). The mechanism of this activity appears to be similar to the one used by Vpr, an HIV-1 protein(More)
OBJECTIVE Pathological findings in neonatal brain injury associated with preterm birth include focal and/or diffuse white matter injury (WMI). Despite the heterogeneous nature of this condition, reactive astrogliosis and microgliosis are frequently observed. Thus, molecular mechanisms by which glia activation contribute to WMI were investigated. METHODS(More)
Pharmaceuticals have been attracting increasing attention in recent years as emerging contaminants, of which the most frequently detected kind in various environments are antibiotics. In this study, crude manganese peroxidase (MnP) prepared from the Phanerochaete chrysosporium, a white rot fungi, was taken as a highly efficient biocatalyst to degrade(More)
Pharmaceuticals are becoming an emerging environmental issue that attracts increasing attention in recent years. This study chose tetracycline (TC) and oxytetracycline (OTC) as examples of pharmaceuticals. Crude lignin peroxidase (LiP) produced by Phanerochaete chrysosporium were used to degrade TC and OTC in vitro. The results illustrated that LiP has a(More)
Two bacterial strains Klebsiella oxytoca Sc and Methylobacterium mesophilicum Sr were isolated and identified from enrichment cultures using dimethyl isophthalate (DMI) as the sole source of carbon and energy, and mangrove sediment as an inoculum. DMI was rapidly transformed by K. oxytoca Sc in the culture with formation of monomethyl isophthalate (MMI),(More)
ETHNOPHARMACOLOGICAL RELEVANCE Jinxin oral liquid (JOL) is used in traditional Chinese medicine (TCM) to treat influenza, cough, asthma, and viral pneumonia, on the basis of Ma Xing Shi Gan Tang (MXSGT) and the clinical experience of Professor Wang Shouchuan, one of the most prestigious pediatricians in China. AIM OF STUDY To investigate the(More)
OBJECTIVE To study the regulation trend of resveratrol on TNF-alpha, IL-1beta, IL-6 expressions in bronchoalveolar layage fluid (BALF) of RSV-infected BALB/c mice at different time points. METHOD RSV-induced BALB/c mice were orally administered with resveratrol. Their BALFs were collected at 24, 72 and 144 h after the first nasal drip with RSV to detect(More)
A strategy to construct high-ordered protein nanowires by electrostatic assembly of cricoid proteins and "soft nanoparticles" was developed. Poly(amido amine) (PAMAM) dendrimers on high generation that have been shown to be near-globular macromolecules with all of the amino groups distributing throughout the surface were ideal electropositive "soft(More)
Although the immune system may provide early protection against cancer, tumors may exploit the healing arm of the immune system to enhance their growth and metastasis. For example, myeloid derived suppressor cells (MDSCs) are thought to promote tumor growth by several mechanisms, including the suppression of T cell activity. It has been suggested that STAT3(More)
