Plant microRNAs (miRNAs) are vital components of the translation control system that regulates plant development and reproduction. The biological function of sly-miR156 was investigated by over-expression in tomato plants. Transgenic tomato plants exhibited a drastically altered phenotype, with reduced height, smaller but more numerous leaves, and smaller(More)
INTRODUCTION Aristolochic acid contained in Chinese herbs has been proved to be nephrotoxic and carcinogenic. Immunosuppression is associated with an increased risk of developing malignancies. What will be the result if these two significant risk factors are concomitantly present in transplanted patients with aristolochic acid nephropathy (AAN)? PATIENTS(More)
Maggots (larvae of Lucilia sericata) have shown therapeutic effects on refractory wounds infected with bacteria, yet the bacterial killing mechanisms are unclear. Herein, we report the isolation and purification of an antibacterial protein from maggots (MAMP). MAMP demonstrated inhibitory activity against both standard strains and clinically isolated(More)
AIM To prepare monoclonal antibodies against rat Nogo molecule and study the distribution of Nogo in rat central nervous system (CNS). METHODS Murine mAbs were prepared by hybridoma technique. The distribution of Nogo in rat CNS was identified by immunofluorescent histochemical staining. RESULTS Three hybridoma cell lines, FMU-Nogo1, FMU-Nogo2 and(More)
Tumour necrosis factor (TNF) family ligands and their corresponding receptors play important roles in the immune system and are involved in immune regulation such as lymphoid development, cell proliferation, differentiation, activation and death. Antibodies against these ligands and receptors together with Fc-fusion proteins, have been particularly useful(More)
Although there have been great advances in the treatment of electrical injuries in the last 20 years, the extremity loss ratio in electrical injuries remains at an unacceptably high level. The primary cause is due to the progressive tissue necrosis which results in the continuous extension of necrosis in the wound, leading to loss of the whole injured(More)
L6 skeletal muscle cells overexpressed ICAM-1 when treated with H2O2. Maximum effect was observed at 200 μM H2O2. Des-aspartate-angiotensin I (DAA-I) concentration-dependently attenuated the overexpression. Maximum attenuation occurred at 10(-10) M DAA-I. H2O2 activated NFκB and its translocation into the nucleus of L6 muscle cells suggesting that NFκB(More)
Crude enzyme from Geotrichum candidum S12 exhibited high activity towards hexanol at pH 4.0, distinguishing it from currently known enzymes. To identify the dominant enzyme contributing to this activity, the crude enzyme extract was separated into different fractions by ammonium sulfate precipitation, MonoQ anion-exchange chromatography, and Sephacryl S-200(More)
CT10/MAGE-C2 is a recently identified antigen that, typically of cancer/testis (CT) antigens, can be found in various malignant tumors and in normal adult testis. As with many other CT antigens, our knowledge is based mainly on mRNA expression data. In the present study, we describe the generation of mAbs to CT10/MAGE-C2 for the analysis of its protein(More)
BACKGROUND Cryptococcosis is a severe fungal infection with a high mortality rate among solid-organ transplant recipients. Today, China is among the countries performing the most kidney transplants worldwide, however data on the association of cryptococcosis with kidney transplantation in mainland China remain scarce and fragmented. METHODS We(More)
