Question: To describe the novel use of a chorioretinal biopsy technique to confirm the microbiological diagnosis of endogenous Escherichia coli (E. coli) endophthalmitis, when other investigations have been proven nondiagnostic.', 'Case report of an 82-year-old white man with endogenous endophthalmitis without a clearly identifiable source of infection.', 'After systemic cultures and multiple aqueous and vitreous samples were unable to identify a causative organism, chorioretinal biopsy of a subretinal abscess was used to confirm the microbiological diagnosis. This ensured appropriate ophthalmic and systemic treatment of infection.

Answer: Do cHORIORETINAL BIOPSY FOR THE DIAGNOSIS OF ENDOGENOUS ENDOPHTHALMITIS DUE TO ESCHERICHIA COLI?

Question: Potent antitumor responses can be induced through cytokine immunotherapy. Interleukin (IL)-2 and granulocyte-macrophage colony-stimulating factor (GM-CSF) are among the most effective cytokines to induce tumor-specific systemic immune responses and can act synergistically. To overcome the limitations of combined use of these two cytokines, we have constructed an IL2-GMCSF fusion protein and characterized its antitumor effects in this study.', 'The expression of IL-2 receptor and GM-CSF receptor of cell lines were detected with quantitative real-time PCR. On this basis, the bioactivities of IL2-GMCSF, especially effects on DC2.4 cells were assayed. Another function of IL2-GMCSF-bridge two types of cells-was assessed by cell contact counting and cytotoxicity assays. The anti-tumor activity in vivo of IL2-GMCSF was evaluated in the melanoma model. The statistical significance among treatment groups were determined by One-Way ANOVA.', 'The fusion protein IL2-GMCSF maintained the activities of IL-2 and GM-CSF, and could significantly promote DC2.4 cell activities, including phagocytosis, proliferation and cytokine secretion. In addition to the inherent cytokine activity, IL2-GMCSF bridges direct cell-cell interactions and enhances splenocyte killing efficacy against multiple tumor cell lines in vitro. Co-injection of IL2-GMCSF and inactivated B16F10 mouse melanoma cells induced complete immunoprotective responses in about 30 % of mice.

Answer: Does fusion cytokine IL-2-GMCSF enhance anticancer immune responses through promoting cell-cell interactions?

Question: This study aimed to investigate the effects of branched-chain amino acid (BCAA) supplementation on recovery of power-producing ability following a strength training (ST) session.', 'Eleven resistance-trained males, performed baseline measures of a countermovement jump (CMJ) and a seated shot-put throw (SSPT). In a counterbalanced fashion, participants were provided with either 20-g of BCAA or a placebo. Each dose was divided into two equal quantities and consumed before and after a ST session consisting of various multi-joint barbell exercises. For both conditions, the CMJ and SSPT were repeated at 24-h post-ST, in addition participants attributed their perceived muscle soreness level via a 200-mm visual analogue scale.', 'Following ST there were significant decrements in CMJ (Baseline; 55.2 7.4-cm, BCAA; 52.8 5.9-cm Placebo; 50.6 7.3-cm) and SSPT (Baseline; 4.55 0.56-m, BCAA; 4.37 0.61-m, Placebo; 4.22 0.64- m) for both conditions in comparison to baseline values (P < 0.05). However, BCAA was shown to attenuate the decrements in CMJ and SSPT performance compared to placebo (P < 0.05). Muscle soreness was significantly increased following ST for both conditions, however there were no differences in attributed values following BCAA and placebo ingestion.

Answer:
Does branched-chain amino acid supplementation attenuate a decrease in power-producing ability following acute strength training?
