Prevalence Of Respiratory Symptoms And Pulmonary Function Status Of Restaurant Workers

@#The cooking process may emit toxic compounds and airway irritants from both the fuel combustion and cooking fumes which is harmful to the respiratory health among the restaurant workers. A cross-sectional study of 243 restaurant workers from the selected restaurants in Sungai Long, Malaysia was conducted. The standardized British Medical Research Council questionnaire on Respiratory Symptoms (1986) was used during the interview to access the symptoms and the spirometry test was performed to evaluate the pulmonary functions of the participants. The data of socio-demography and occupational characteristics were also collected. The most complaint respiratory symptoms by the restaurant workers were breathlessness, which accounted for 33.7%, followed by wheezing (14%). The mean values of all pulmonary function tests (PFT) of the restaurant workers were within the normal range (>80%), except for the Peak Expiratory Flow (PEF) (79.09%). The results of the bivariate statistical analysis, Chi-square, ANOVA and t-test, showed the determining factors of the respiratory health among the workers were workers’ age and gender in addition to the working duration and the ethnicity. The restaurant workers in Sungai Long were at risk of developing respiratory symptoms and lower pulmonary function values due to prolonged exposure to cooking fumes. Emphasis should be given to the safety and health of restaurant workers and health education should be provided to the restaurant workers and owners. Strategies to increase notification of such occurrences among these workers should be looked into by related agencies in the country.

MLKL forms cation channels / 中国药理学与毒理学杂志

OBJECTIVE To investigate how MLKL functions on the membrane and explore its electrophysiological characters and structure. METHODS The full-length human MLKL were expressed in SF21 cells and purified using glutathione-sepharose affinity chromatography. The currents of purified MLKL proteins were recorded in avoltage-clamp mode using a Warner BC-535 bilayer clamp amplifier. The currents were digitized using pCLAMP 10.2 software. HEK293 cells were cultured and transfected with MLKL plasmid. Cell viability was examined using the CellTiter- Glo Luminescent Cell Viability Assay kit. RESULT MLKL forms cation channels that are permeable preferentially to Mg2+ rather than Ca2+ in the presence of Na+ and K+. Moreover,each MLKL monomer contains five transmembrane helices:H1, H2, H3 , H5 and H6 of the N-terminal domain which is sufficient to form channels. Finally, MLKL-induced membrane depolarization and cell death exhibit a positive correlation to its channel activity.

Development of pollen mediated activation tagging system for Phalaenopsis and Doritaenopsis

In the present study, a novel plant transformation system for Doritaenopsis and Phalaenopsis has been developed. The pollen-mediated activation tagging system was established by artificial pollination. The pollens, co-cultured with Agrobacterium tumefaciens strain EHA105 harbouring an activation tagging vector (pTAG-8), were used for pollination. In order to optimize the transformation efficiency, several factors (concentration of A. tumefaciens, concentration of acetosyringone during co-cultivation and the duration of co-cultivation) known to influence Agrobacterium-mediated DNA transfer were examined. A concentration of 0.5-1 x 10(8) CFU/ml for A. tumefaciens, 0.1 mM acetosyringone, and 6 hrs of co-culture period were found to be the optimal condition for high transformation efficiency. Integration of T-DNA into the genome of putative transgenic plants was confirmed by PCR and DNA blot analyses. Single copy of the transgene was observed in all transgenic plants analyzed. Most of the transgenic plants had a morphologically normal phenotype and the overall capsule formation efficiency was similar to control plant. Our results showed a new approach of genetic transformation in orchids and this method can be employed for genetic improvement of the orchids.

Plastic Changes of Synapses and Excitatory Neurotransmitter Receptors in Facial Nucleus Following Facial-facial Anastomosis / 华中科技大学学报（医学）（英德文版）

The remodeling process of synapses and eurotransmitter receptors of facial nucleus were observed. Models were set up by facial-facial anastomosis in rat. At post-surgery day (PSD) 0, 7, 21 and 60, synaptophysin (p38), NMDA receptor subunit 2A and AMPA receptor subunit 2 (GIuR2) were observed by immunohistochemical method and emi-quantitative RT-PCR, respectively. Meanwhile, the synaptic structure of the facial motorneurons was observed under a transmission electron microscope (TEM). The intensity of p38 immunoreactivity was decreased, reaching the lowest value at PSD day 7, and then increased slightly at PSD 21. Ultrastructurally, the number of synapses in nucleus of the operational side decreased, which was consistent with the change in P38 immhnoreactivity. NMDAR2A mRNA was down-regulated significantly in facial nucleus after the operation (P00<0.05), whereas AMPAR2 mRNA levels remained unchanged (P>0.05). The synapses innervation and the expression of NMDAR2A and AMPAR2 mRNA in facial nucleus might be modified to suit for the new motor tasks following facial-facial anastomosis, and influenced facial nerve regeneration and recovery.

Site-directed mutagenesis of conserved Thr407, Asp433 and Met464 residues in small subunit of Escherichia coli gamma-glutamyltranspeptidase.

Sequence comparison showed that residues Thr407, Asp433, and Met464 in the small subunit of Escherichia coli gamma-glutamyltranspeptidase (EcGGT) were conserved in the aligned enzymes. In this study, we further investigated the functional significance of these conserved residues by site-directed mutagenesis. The wild-type and mutant enzymes were overexpressed in the recombinant E. coli M15 cells and purified to near homogeneity by Ni2+-NTA resin. Except M464L, other mutants had shown no GGT activity under enzyme assay conditions and activity staining. Furthermore, mutations on these residues impaired the capability of autocatalytic processing of the enzyme. Based on these observations, it is concluded that these residues play an important role in the enzyme maturation.

Increased circulating CCR3+ type 2 helper T cells in house dust mite-sensitive Chinese patients with allergic diseases.

Chemokine receptor expression has been shown to be associated with the differentiation of T helper cells. The CCR3, CXCR4 and CCR5 expression on circulating T cells were studied in 30 house dust mite sensitive-patients with allergic diseases and in another 30 healthy controls. The expression was analyzed in CD4, CD8 and double negative (DN) T cells by triple fluorescence staining. In addition, intracellular cytokine staining was performed in the CCR3+ CD4+ T cells. Increased circulating portions of CCR3+ CD4+ T cells and CCR3+ DN T cells were found in these patients (p < 0.01). There was no statistically significant difference in the expression of CXCR4 and CCR5 on T cells. The follow-up data of the patients did not show a statistically significant change in the CCR3 expression. IL-4 was expressed within CCR3+ CD4+ T cells upon activation. The IL-4 secreting CCR3+ type 2 T helper cells may play a pathogenetic role in immune responses of house dust mite-sensitive Chinese patients with allergic diseases.

Correlation between the renal C1q deposition and serum anti-C1q antibody: a potential role of anti-C1q antibody in lupus nephritis.

The anti-C1q antibody has been shown to be associated with lupus patients with renal involvement. We conducted a study to determine the relationship between the serum anti-C1q titer and the renal deposition of C1q. The serum anti-C1q was measured in 26 healthy controls and 47 systemic lupus erythematosus (SLE) patients who were divided into 2 groups as non-nephritis and nephritis SLE. We analyzed the relationship between the anti-C1q titers and SLE, renal C1q staining and the WHO classification for lupus nephritis. The result revealed that the serum anti-C1q was present in 50.8% of the SLE patients, that its levels in those with renal involvement were significantly higher than in the normal control group (61.540 +/- 87.720 U/ml vs 15.750 +/- 2.530 U/ml, p = 0.005). Besides, the serum anti-C1q levels were higher in the patients with lupus nephritis with C1q deposition in the kidney tissue (66.038 +/- 91.141 U/ml vs 16.652 +/- 3.097 U/ml, p < 0.01). There seems to be evidence supporting that the autoantibody anti-C1q might play a pathogenic role in lupus nephritis.
