  • Targeting fibroblast growth factor receptors (FGFRs) has been slow compared to other targeted cancer therapies for receptor tyrosine kinases, such as epidermal growth factor receptors. The low efficacy and variable response have limited the growth of FGFR inhibitors in clinical use. Nevertheless, recent systematic and genomic approaches have identified the biological conditions for effectively targeting FGFRs and can accelerate the development of targeted drugs. Under clinical and preclinical trials, the inhibitors started fast growing furious races to target FGFRs. Finally, FGFRs will be more actionable and targetable with more precise and effective drugs at the end of the race, passing the finish line.

  • Purpose : Granisetron is a potent, the most selective 5-HT3 receptor antagonist and is reported to b effective in treatment of radiation-induced emesis. The antiemetic efficacy and safety of oral granisteron was evaluated in patients with receiving highly emetogenic treatment by conventional fractionated irradiation. Materials and Methods : Patients with various cancers who were being treated with irradiation were accrued into the present study. The intensity of nausea was evaluated on first 24 hours and on day-7 by patients according to the degree of interference with normal daily life as followings; a) none; b) present but no interference with normal daily life (mild): c) interference with normal daily life (moderate): and d) bedridden because of nausea (severe). Non or mild state was considered to indicate successful treatment. The efficacy of antiemetic treatment was graded as follows; a) complete response; no vomiting, no worse than mild nausea and receive no rescue antiemetic therapy over the 24h period, b) major response; either one episode of vomiting or moderate/severe nausea or had received rescue medication over 24h period, or any combination of these, c) minor response; two to four episodes of vomiting over the 24h period, regardless of nausea and rescue medication, d) failure; more than four medication. The score of the most symptom was recorded and the total score over 24 hours was summarized. The complete or major response was considered to indicate successful treatment. Results : A total of 10 patients were enrolled into this study, and all were assessable for efficacy analysis. Total nausea control was achieved in 90$\%$ (9/10:none=60$\%$ plus mild=30$\%$) of total patients after 7 days. The control of vomiting by granisteron was noted in seven patients (70$\%$) of complete response and three (30$\%$) of major response with a hundred-percent successful treatment over 7 days. The minor response or treatment failure were not observed. No significant adverse events or toxicities from granisetron were recorded in patient receiving granisetron. Conclusion : We concluded that granisetron is a highly effective antiemetic agent in controlling radiotherapy-induced nausea or vomiting with a minimal toxicity profile.

  • Because of the burgeoning demand of the energy, the countries are finding sustainable solutions for these emerging challenges. Demand Side Management is playing a significant role in managing the demand with an aim to support the electrical grid during the peak hours. However, advancement in controls and communication technologies, the aggregators are appearing as a third party entity in implementing demand response program. In this paper, a detailed mathematical framework is discussed in which the aggregator acts as an energy service provider between the utility and the consumers, and facilitate the consumers to actively participate in demand side management by introducing the new concept of demand reduction bidding (DRB) under constrained direct load control. Paper also presented an algorithm for the proposed framework and demonstrated the efficacy of the algorithm by considering few case studies and concluded with simulation results and discussions.

  • For decades, scientists and clinicians have examined methods of measuring scalp hair growth. There has been a greater need for reliable, economical and minimally invasive means of measuring hair growth and, specifically, response to Oriental medicine therapy. We review the various methods of measurement described to date, their limitations and value to the clinician. In our opinion, the potential of computer-assisted technology in this field is yet to be maximized and the currently available tools are less than ideal. The most valuable means of measurement at the present time are global photography and phototrichogram-based techniques (with digital image analysis). Subjective scoring systems are also of value in the overall assessment of response to therapy and these are under-utilized and merit further refinement.

  • The purpose of this study is to evaluate the effectiveness of Scirpi rhizoma ethanol extract (SREE) on skin whitening using in vitro test. In the antioxidative activities, it was found that SREE contains 38.9 mg/g of polyphenol and 74.5 mg/g of flavonoid in total. In the electron donating ability, SREE showed a dose-dependent response, showing a high antioxidative capacity of 86.1% at 1000 ppm. It was found that the maximum permissible level of SREE to Melan-a cells was over 200 ppm, showing a quite low toxicity of SREE against Melan-a cells. Both in the inhibitory measurement for tyrosinase activity and melanogenesis using Melan-a cells, SREE presented a dose-dependent response with excellent efficacy.

  • This study investigates the optimum design parameters of a superelastic friction base isolator (S-FBI) system through a multi-objective genetic algorithm to improve the performance of isolated buildings against near-fault earthquakes. The S-FBI system consists of a flat steel-PTFE sliding bearing and superelastic NiTi shape memory alloy (SMA) cables. Sliding bearing limits the transfer of shear across the isolation interface and provides damping from sliding friction. SMA cables provide restoring force capability to the isolation system together with additional damping characteristics. A three-story building is modeled with S-FBI isolation system. Multiple-objective numerical optimization that simultaneously minimizes isolation-level displacements and superstructure response is carried out with a genetic algorithm in order to optimize S-FBI system. Nonlinear time history analyses of the building with optimal S-FBI system are performed. A set of 20 near-fault ground motion records are used in numerical simulations. Results show that S-FBI system successfully control response of the buildings against near-fault earthquakes without sacrificing in isolation efficacy and producing large isolation-level deformations.

  • Fiber reinforced polymer (FRP) sheets are the most efficient structural materials in terms of strength to weight ratio and its application in strengthening and retrofitting of a structure or structural elements are inevitable. The performance enhancement of structural elements without increasing the cross sectional area and flexible nature are the major advantages of FRP in retrofitting/strengthening work. This research article presents a detailed study on the inelastic response of conventional and retrofitted Reinforced Concrete (RC) frames using Carbon Fibre Reinforced Polymers (CFRP) and Glass Fiber Reinforced Polymers (GFRP) subjected to quasi-static loading. The hysteretic behaviour, stiffness degradation, energy dissipation and damage index are the parameters employed to analyse the efficacy of FRP strengthening of brick in-filled RC frames. Repair and retrofitting of brick infilled RC frame shows an improved load carrying and damage tolerance capacity than control frame.

  • The relative efficacy on the renal function of rabbits by oral administration of furosemide and 1 : 2 furosemide-PVP coprecipitate was compared by measuring the urine volume in response to maximal response and the amounts of electrolytes excreted in urine. The furosemide produced a rapid onset, short duration of diuresis, in contrast, the 1: 2 furosemide-PVP coprecipitate, a rapid onset, significantly larger magnitude, and longer duration of diuresis and therefore the bioavailability of furosemide from the coprecipitate were increased significantly. The average urine volume and the amount of sodium and potassium excreted in urine were increased about 2.9-, 14.8-, and 1.8-fold from furosemide, and about 6.2-, 24.2-, and 3.6-fold from 1 : 2 furosemide- PVP 40,000 coprecipitate, rerpectively, comparing by their control values.

  • This paper focuses on presenting modeling considerations and insight into the performance of typical straight, curved, and skewed box-girder bridges in California which form the bulk of the bridge inventory in the state. Three case study bridges are chosen: Meloland Road Overpass, Northwest Connector of Interstate 10/215 Interchange, and Painter Street Overpass, having straight, curved, and skewed superstructures, respectively. The efficacy of nonlinear dynamic analysis is established by comparing the response from analytical models to the recorded strong motion data. Finally insights are provided on the component behavioral characteristics and shift in vulnerability for each of the bridge types considered.
