“…However, the use of latamoxef was not reduced significantly after intervention. Cefazolin [9] and cefradine [10] are first-generation cephalosporins, which have evidence-based medical research, and they are recommended in the perioperative period. Cefathiamidine [11] is the first-generation cephalosporins and the applicant of which is not a mistake in matters of principle, was significantly increased in use after intervention.…”

Objective: Surgical site infections (SSI) is a serious complication of surgery. Perioperative antibacterial prophylaxis is one of the most effective methods to prevent SSI. The aim of this study was to evaluate the effect of interventions on perioperative antibacterial prophylaxis in neurosurgery. Method: We intervened and assessed the perioperative antibacterial prophylaxis from adult patients with a neurological surgery in the First Affiliated Hospital of Jinan University (Guangzhou, China) between May 2014 and December 2014. A total of 279 neurosurgical cases were chosen among which 145 cases were before intervention and 134 after intervention. This study discussed the indications, selection of varieties, timing of the first dose, and application time of antibacterial drugs before and after intervention. Results: Investigation and analysis were performed in the perioperative antibacterial prophylaxis. Compared with the pre-intervention phase, rationalities of perioperative antibiotics prophylaxis in the post-intervention phase were significantly increased. The rational drug selection and the rational timing of using antibacterial after intervention were significantly increased. In addition, the average duration of antibiotic prophylaxis in the post-intervention phase was significantly shorter than the pre-intervention phase. Conclusion: The intervention of perioperative antibiotics prophylaxis was effective and feasible. It contributed to promoting the rational use of perioperative antibiotics prophylaxis in neurosurgery.

“…For some microalgae, pre-acclimation to sub-toxic concentrations of the EC may be required to initiate enzyme production in order to screen for biodegradation potential (Sutherland and Ralph, 2019). For example, microalgal biodegradation of several different antibiotics was enhanced following pre-exposure of the microalgal strain to low levels of the antibiotic due to increased production of antioxidants, including xanthophylls, by the cells (Chen et al, 2015;Xiong et al, 2017). Biodegradation may also lead to intermediary products that could be similarly, or more toxic, than the parent compound.…”

Mankind has recognized the value of land plants as renewable sources of food, medicine, and materials for millennia. Throughout human history, agricultural methods were continuously modified and improved to meet the changing needs of civilization. Today, our rapidly growing population requires further innovation to address the practical limitations and serious environmental concerns associated with current industrial and agricultural practices. Microalgae are a diverse group of unicellular photosynthetic organisms that are emerging as next-generation resources with the potential to address urgent industrial and agricultural demands. The extensive biological diversity of algae can be leveraged to produce a wealth of valuable bioproducts, either naturally or via genetic manipulation. Microalgae additionally possess a set of intrinsic advantages, such as low production costs, no requirement for arable land, and the capacity to grow rapidly in both large-scale outdoor systems and scalable, fully contained photobioreactors. Here, we review technical advancements, novel fields of application, and products in the field of algal biotechnology to illustrate how algae could present high-tech, low-cost, and environmentally friendly solutions to many current and future needs of our society. We discuss how emerging technologies such as synthetic biology, highthroughput phenomics, and the application of internet of things (IoT) automation to algal manufacturing technology can advance the understanding of algal biology and, ultimately, drive the establishment of an algal-based bioeconomy.

“…Chen et al [183] investigated the removal efficiency of cefradine by Chlorella pyrenoidosa in a sequencing batch reactor and identified different results between the first batch treatment and the second, where higher algal growth inhibition rates were observed; however, the alga produced more photosynthetic pigments, enhancing its photosynthetic metabolism as a way of adaptation to more harmful environmental conditions.…”

The occurrence and fate of pharmaceuticals in the aquatic environment is recognized as one of the emerging issues in environmental chemistry. Conventional wastewater treatment plants (WWTPs) are not designed to remove pharmaceuticals (and their metabolites) from domestic wastewaters. The treatability of pharmaceutical compounds in WWTPs varies considerably depending on the type of compound since their biodegradability can differ significantly. As a consequence, they may reach the aquatic environment, directly or by leaching of the sludge produced by these facilities. Currently, the technologies under research for the removal of pharmaceuticals, namely membrane technologies and advanced oxidation processes, have high operation costs related to energy and chemical consumption. When chemical reactions are involved, other aspects to consider include the formation of harmful reaction by-products and the management of the toxic sludge produced. Research is needed in order to develop economic and sustainable treatment processes, such as bioremediation and biosorption. The use of low-cost materials, such as biological matrices (e.g., algae and fungi), has advantages such as low capital investment, easy operation, low operation costs, and the non-formation of degradation by-products. An extensive review of existing research on this subject is presented.
