Ionic liquids (ILs) have attracted much attention due to their tuneable properties according to their needs. However, the application of ILs just as solvent should pay much expense with respect to industrial viewpoint. Various usage of ILs as an active catalyst for the efficient organic transformation reactions have resulted in opening a new level of application fields [1-6]. Accordingly, there have been numerous reports on the dramatic enhancement in their catalytic activities just by incorporating metal salts into ILs [7-9]. Catalytic transformation of carbon dioxide into useful organic compounds has also attracted much attention during the last two decades due to economic and environmental benefits arising from the utilization of renewable source and the growing concern on the greenhouse effect. CO<sub>2</sub> is an abundant, cheap, and safe C1 building block in organic synthesis; however, due to the inert nature of CO<sub>2</sub>, efficient catalytic processes for chemical fixation remain a significant challenge. Herein, we present a couple of examples for ILs-based catalysts which provides enhanced activity towards various organic syntheses which meets the green chemistry.

The clinical spectrum of infections caused by non-typhoid Salmonella spp. includes gastroenteritis, enteric fever,bacteremia, and extraintestinal localized complications, especially in immunocompromised hosts. Here we report a patient with severe aplastic anemia developing left iliopsoas abscess caused by non-typhoid Salmonella (NTS),which was successfully treated by prolonged antibiotic treatment and repeated debridement. Our data indicate that aplastic anemia is a risk factor for infection caused by NTS.

An immune-enhancing strain, Lactobacillus plantarum Pi06, isolated from a healthy infant was used for biomass production following optimization of the medium in shake-flask culture. Preliminary studies showed that commercial MRS medium and cultivation under static conditions generated higher biomass production than four other tested media with or without a shaking condition. The selected medium composition, consisting of glucose,yeast extract, soy peptone, ammonium citrate, and corn steep liquor, was further optimized using a systematic method that integrated the Taguchi array design and the Box–Behnken method. The response effects of these factors were first investigated using Taguchi design under an L16 (45) array. The suggested medium composition,derived from Statistica 7.1 using the Taguchi design, was applied to cultivate cells and a biomass of 7.16 g dry cell weight (DCW)/L was obtained. Response surface methodology based on the Box–Behnken method for the three response variables of glucose, yeast extract, and corn steep liquor was then used to further increase the biomass level to 8.94 g DCW/L. The resulting optimum medium consisted of 35 g/L glucose, 35 g/L yeast extract, and 40 mL/L corn steep liquor. Compared with the initial medium, the biomass yield was improved from 4.31 to 8.94 g DCW/L, an enhancement of approximately 107%.
