It not only involves interesting fundamental questions that remain inconclusive and hence need further investigation, but also has the potential to revolutionize data storage technologies because such an opto-magnetic interaction provides an ultrafast and energy-efficient means to control magnetization. Fruitful progress has been made in this area over the past quarter century. In this paper, we review the state-of-the-art experimental and theoretical studies on magnetization dynamics and switching in ferromagnetic materials that are induced by ultrafast lasers. We start by describing the physical mechanisms of ultrafast demagnetization based on different experimental observations and theoretical methods. Both the spin-flip scattering theory and the superdiffusive spin transport model will be discussed in detail. Then, we will discuss laser-induced torques and resultant magnetization dynamics in ferromagnetic materials. Recent developments of all-optical switching (AOS) of ferromagnetic materials towards ultrafast magnetic storage and memory will also be reviewed, followed by the perspectives on the challenges and future directions in this emerging area. Preoperative chemotherapy for gastric cancer may be effective from the standpoint of compliance, although there is insufficient evidence of its efficacy. We analyzed a multicenter database to clarify whether preoperative chemotherapy influenced the short-term outcomes of gastrectomy. We analyzed, retrospectively, 3571 patients who underwent gastrectomy between January, 2010 and December, 2014. Patients with clinical stage-III gastric adenocarcinoma were divided into a neoadjuvant chemotherapy (NAC) group and a non-NAC group. We performed propensity-matched comparative analysis to stratify the groups accord
