To manipulate physically individual synapses in a living organism, we have developed a laser ablation technique for removing single synapses in live neurons in C. elegans that operates without apparent

damage to the axon. As a complementary technique, we applied microfluidic immobilization of C. elegans to facilitate long-term fluorescence imaging and observation of neuronal development. With this technique, we directly demonstrated the existence of competition between developing synapses in the HSNL motor neuron. (C) 2008 Elsevier B.V. All rights reserved.”
“This study investigated the expression of interleukin-17 (IL-17) and T cell immunoglobulin mucin and domain-containing molecule-3 (Tim-3) in bronchoalveolar lavage fluid (BALF) of asthmatic mice and the effect of dexamethasone (DEX) on these factors. Thirty-six mice were randomly divided into three groups: normal group, asthmatic group and DEX group. The HSP990 price mouse model of asthma was established by sensitization with ovalbumin in both the asthmatic and DEX groups. The levels of IL-6, IL-10, IL-17 and TGF-beta were measured in BALF by enzyme-linked immunesorbent assay (ELISA). The mRNA expression level of Tim-3 was detected by reverse transcription polymerase chain reaction (RT-PCR). The ratio of Tim-3+CD4+ cells to total CD4+ cells in BALF was determined BIIB057 by flow cytometry. Differential inflammatory

cells in BALF were detected. The correlations among IL-17, IL-6, IL-10, Tim-3 and inflammatory cells were analyzed. The results showed that the levels of IL-17, IL-6 and Tim-3 were substantially increased and the IL-10 level decreased in BALF in the asthmatic mice, which was significantly reversed by DEX treatment. IL-17 expression was positively correlated with IL-6 and Tim-3 CFTRinh-172 cell line expression and the number of inflammatory cells but negatively with IL-10 expression. These results indicate

that the increased expression of IL-17 and Tim-3 in BALF may be implicated in the occurrence and development of asthmatic inflammation; the mechanism by which DEX suppresses asthmatic airway inflammation involves down-regulation of IL-17 and Tim-3 levels.”
“The presence of macroscopic fat in an adrenal mass has classically been associated with myelolipoma. Adrenocortical carcinoma is typically an aggressive malignancy with a poor prognosis. The presence of macroscopic fat is not a characteristic finding in adreocortical carcinoma or other adrenal malignancies. We report a case of a newly discovered large adrenal mass containing multiple areas of macroscopic fat, which was pathologically proven to represent an adrenocortical carcinoma.”
