Discriminative sensing of chiral species with a convenient and robust system is a challenge in chemistry, pharmaceutics and particularly in biomedical science. Advanced nanohybrid materials for discrimination of these biologically active molecules can be developed by combination of individual obvious advantages of different molecular scaffolds. Herein, we report on the comparison of the performance of cyclodextrin functionalized graphene derivatives (x-CD/rGO, x: α-, β-, γ-) for discrimination of DOPA enantiomers...

Carmel M Hawley, Stephen G Holt
Appropriate targets for parathyroid hormone (PTH) in patients with chronic kidney disease (CKD) stages 3-5D are controversial, as are the means by which these targets might be achieved. Secondary hyperparathyroidism is linked to symptoms like bone pain and itch, in addition to less clinically overt issues like bone fragility as well as vascular and soft tissue calcification which may lead to adverse hard endpoints, particularly fracture and death. Recognized therapies for managing a rising PTH include vitamin D analogues, with or without calcimimetic (where available), in addition to management of serum mineral concentrations with diet, binders and dialysis...

Neutropenia is a serious toxic complication of chemotherapeutic treatment. For years, mathematical models have been developed to better predict hematological outcomes during chemotherapy in both the traditional pharmaceutical sciences and mathematical biology disciplines. An increasing number of quantitative systems pharmacology (QSP) models that combine systems approaches, physiology, and pharmacokinetics/pharmacodynamics have been successfully developed. Here, I detail the shift towards QSP efforts, emphasizing the importance of incorporating systems-level physiological considerations in pharmacometrics...

REVIEW
Xiangying Yu, Zhong-Ping Yao
Chiral analysis is of great importance to fundamental and applied research in chemical, biological and pharmaceutical sciences. Due to the superiority of mass spectrometry (MS) over other analytical methods in terms of speed, specificity and sensitivity, chiral analysis by MS has attracted much interest in recent years. Chiral analysis by MS typically involves introduction of a chiral selector to form diastereomers with analyte enantiomers, and comparison of the behaviors of diastereomers in MS. Chiral differentiation can be achieved by comparing the relative abundances of diastereomers, the thermodynamic or kinetic constants of ion-molecule reactions of diastereomers in the gas phase, the dissociation of diastereomers in MS/MS, or the mobility of diastereomers in ion mobility mass spectrometry...

In super-cooled aqueous solutions, ice nucleation is the initial stage of the freezing process. In this paper, we present experimental results that indicate that during the freezing of aqueous solutions, freeze-induced phase separation (FIPS) into pure ice and a freeze-concentrated solution (FCS) takes place. Our observations involve the use of an optical cryo-microscope (OC-M) to record images and movies. The results visually indicate for the first time that there are two freezing processes for (NH4)3H(SO4)2/H2O solutions: (i) contact freezing, as is the case for pure water drops, and (ii) the Wegener-Bergeron-Findeisen process, which is the growth of frozen drops (ice) at the expense of liquid ones...

Cancer transcriptome analysis is one of the leading areas of Big Data science, biomarker, and pharmaceutical discovery, not to forget personalized medicine. Yet, cancer transcriptomics and postgenomic medicine require innovation in bioinformatics as well as comparison of the performance of available algorithms. In this data analytics context, the value of network generation and algorithms has been widely underscored for addressing the salient questions in cancer pathogenesis. Analysis of cancer trancriptome often results in complicated networks where identification of network modularity remains critical, for example, in delineating the "druggable" molecular targets...

Recently, there has been great interest in studying ultrasensitive detection and characterization of biomolecules using plasmonic particles, because they are of considerable importance in biomedical science and pharmaceutics. So far, all the theories on plasmon-induced circular dichroism (CD) have been based on the dipole approximation; the electric quadrupolar contribution is generally considered to be relatively small and neglected. Here we demonstrate that the electric quadrupolar contribution not only cannot be ignored, but it also plays a key role in many cases...

Joshua A Jackman, Abdul Rahim Ferhan, Nam-Joon Cho
In recent years, nanoplasmonic sensors have become widely used for the label-free detection of biomolecules across medical, biotechnology, and environmental science applications. To date, many nanoplasmonic sensing strategies have been developed with outstanding measurement capabilities, enabling detection down to the single-molecule level. One of the most promising directions has been surface-based nanoplasmonic sensors, and the potential of such technologies is still emerging. Going beyond detection, surface-based nanoplasmonic sensors open the door to enhanced, quantitative measurement capabilities across the biointerfacial sciences by taking advantage of high surface sensitivity that pairs well with the size of medically important biomacromolecules and biological particulates such as viruses and exosomes...

 I introduce the current pharmaceutical education system in Japan, focusing on regulatory science. University schools or faculties of pharmaceutical science in Japan offer two courses: a six-year course for pharmacists and a four-year course for scientists and technicians. Students in the six-year pharmaceutical course receive training in hospitals and pharmacies during their fifth year, and those in the four-year life science course start research activities during their third year. The current model core curriculum for pharmaceutical education requires them to "explain the necessity and significance of regulatory science" as a specific behavior object...

 In the field of pharmaceutical sciences, the subject of regulatory science (RS) includes pharmaceuticals, food, and living environments. For pharmaceuticals, considering the balance between efficacy and safety is a point required for public acceptance, and in that balance, more importance is given to efficacy in curing disease. For food, however, safety is the most important consideration for public acceptance because food should be essentially free of risk. To ensure food safety, first, any hazard that is an agent in food or condition of food with the potential to cause adverse health effects should be identified and characterized...

 For providing appropriate pharmacotherapy, "Doing the right things, and doing things right" are necessary. Additionally, vigilance is required for the appropriate use of pharmaceuticals. Evidence-based medicine has been a common approach to healthcare, and many guidelines have been published. In addition, risk management plans (RMPs) are developed upon the approval of new drugs. Therefore an environment to provide the best healthcare based on scientific evidence has been developed. When putting RMPs into practice, it is necessary to understand and utilize regulatory science (RS)...
