“…As demonstrated, statistical programs have been invented for carrying out a large number of experiments in a shorter period of time and more efficiently to obtain optimum conditions, which can overcome these aforementioned defects rationally [21,22]. Response surface methodology (RSM), as a statistical method, is used to generate a model, analyze the effects of operating parameters and optimize the process conditions [23]. Furthermore, the central composited design (CCD) is a standard RSM design to analyze the relationship between the several variables and one or more response variables, which can also create a second-order response surface model in the optimization of processes [22,24].…”

Abstract:In the present work, the photocatalytic performance of P25TiO 2 was investigated by means of the degradation of aspirin, while the reaction system was systematically optimized by central composite design (CCD) based on the response surface methodology (RSM). In addition, three variables of initial pH value, initial aspirin concentration and P25 concentration were selected to assess the dependence of degradation efficiencies of aspirin. Meanwhile, a predicted model of degradation efficiency was estimated and checked using analysis of variance (ANOVA). The results indicated that the PC removal of aspirin by P25 was significantly influenced by all these variables in descending order as follows: P25 concentration > initial aspirin concentration > initial pH value. Moreover, the parameters were optimized by the CCD method. Under the conditions of an initial pH value of 5, initial aspirin concentration of 10 mg/L and P25 concentration of 50 mg/L, the degradation efficiency of aspirin was 98.9%with 60 min of Xenon lamp irradiation. Besides, based on the liquid chromatography-mass spectrometry measurements, two main PC degradation pathways of aspirin by TiO 2 were deduced and the tentative degradation mechanism was also proposed.

“…It is now accept FAD audit certification [93]. However, tofacitinib for the treatment of moderate and severe Crohn' s disease in phase II clinical study [94] showed no obvious curative effect; 280 patients with moderately severe Crohn' s disease studied in the clinical trial were randomly assigned to 5 mg twice a day (n = 86), 10 mg twice a day (n = 86), 15 mg twice a day (n = 16), and placebo (n = 92, one are excluded), and accepted the specified treatment, respectively; a total of 236 patients completed the induction research, the primary end point for 8 weeks to relieve clinical (CDAI < 150). One hundred and eighty patients enrolled in the maintenance study, including 128 who completed the induction study, were randomized (placebo, n = 59; tofacitinib 5 mg twice daily, n = 60; Tofacitinib 10 mg twice daily, n = 61) and received the prescribed treatment.…”

The therapeutic effect of inflammatory bowel disease has improved in the past decades, but most of patients cannot tolerate, do not respond to drugs, or relapse after treating with conventional therapy. Therefore, new and more effective treatment methods are still needed in treatment of IBD. In this review, we will discuss the relevant mechanisms and the latest research progress of biologics (anti-TNF treatments, interleukin inhibitors, integrin inhibitors, antisense oligonucleotide, and JAK inhibitors) for IBD, focus on the efficacy and safety of drugs for moderate-to-severe IBD, and summarize the clinical status and future development direction of biologics in IBD.

“…An overview of ultrasound effects on microbial safety is presented in Table 1. Liu et al [89] investigated the inactivation of Saccharomyces cerevisiae under varying conditions such as bacterial load concentration, pH, and treatment temperature and determined that ultrasound had the most significant role in the inactivation of the bacteria. Kang et al [90] examined the effects of ultrasound on the number of Escherichia coli O157:H7 and vegetative cells of Bacillus cereus in brining and beef during the curing processing.…”

is review gives an overview of the impact of novel nonthermal food technologies on food safety, on quality, and on the environment. It con rms that research in this eld is mainly focused on analyzing microbial and/or chemical aspects of food safety. However, recent research shows that in spite of various food safety bene ts, some negative (quality oriented) features occur. Finally, this paper shows the necessity of analyzing the environmental dimension of using these technologies.
