#1
Tanvi M Deshpande, Anisul Quadir, Sakae Obara, Stephen W Hoag
Hydroxypropyl methylcellulose acetate succinate (HPMCAS) has been widely used in amorphous solid dispersions and as an enteric coating polymer. Under aqueous coating conditions and at elevated coating temperatures, HPMCAS particles tend to aggregate and clog the spray-nozzle, hence interrupting the coating process. This research focused on how plasticizers and surfactants, excipients used for aqueous coating, affect the properties and stability of HPMCAS. This information would be useful in identifying suitable excipients for developing a stable HPMCAS aqueous enteric coating formulation...

Closed-loop drug delivery promises autonomous control of pharmacotherapy through the continuous monitoring of biomarker levels. For decades, researchers have strived for portable closed-loop systems, capable of treating ambulatory patients with chronic conditions such as diabetes mellitus. After years of development, the first of these systems have left the laboratory and entered commercial use. This long-awaited advance reflects recent development of chronically stable implantable biosensors, able to accurately measure biomarker levels in vivo...

Samarendra Das, Anil Rai, D C Mishra, S N Rai
Selection of informative genes from high dimensional gene expression data has emerged as an important research area in genomics. Many gene selection techniques have been proposed so far are either based on relevancy or redundancy measure. Further, the performance of these techniques has been adjudged through post selection classification accuracy computed through a classifier using the selected genes. This performance metric may be statistically sound but may not be biologically relevant. A statistical approach, i...

The peptide relaxin was first identified as an important circulating hormone during pregnancy over 90 years ago. Research over many years defined the numerous biological roles that relaxin plays throughout pregnancy in many mammalian species. These important biological actions have led to the testing of relaxin as a therapeutic agent for a number of indications. The discovery of the relaxin receptor, RXFP1, in 2002 facilitated the better understanding of the cellular targets of relaxin, its mechanism of action and enabled the development of relaxin mimetics and screening for small molecule agonists...

High-grade serous ovarian cancer (HGSC) is the leading cause of morbidity and mortality from gynecologic malignancy. Overall survival remains low, due to the nearly ubiquitous emergence of platinum-resistance and the paucity of effective next-line treatments. Current cell culture-based models show limited similarity to HGSC and are therefore unreliable predictive models for pre-clinical evaluation of investigational drugs. This deficiency could help explain the low overall rate of successful drug development and the decades of largely unchanged approaches to HGSC treatment...

Owing to their excellent adsorption properties compared with those of the corresponding bulk materials, nanoparticles have been widely applied in many fields. Their properties depend on the thermodynamics and kinetics of adsorption, which depend on the particle size. In this paper, we present universal theories of the thermodynamics and kinetics for nano-adsorption that have been developed over the past few years. Theoretically, we have derived relationships between the adsorption thermodynamic properties and the particle size, as well as those between the adsorption kinetic parameters and the particle size...

Mosquito control using chemical insecticides is facing a major challenge due to development of insecticide resistance. Improving the efficiency of existing insecticides using synergistic secondary metabolites of biological origin is increasingly being researched. Herein, we evaluated the toxicity of Fusarium oxysporum extract alone and in binary combinations with temephos, on larvae and pupae of Anopheles stephensi, Aedes aegypti and Culex quinquefaciatus. F. oxysporum extract was characterized using TLC, FT-IR and GC-MS...

Self-propagating gene drive technologies have a number of desirable characteristics that warrant their development for the control of insect pest and vector populations, such as the malaria-transmitting mosquitoes. Theoretically easy to deploy and self-sustaining, these tools may be used to generate cost-effective interventions that benefit society without obvious bias related to wealth, age or education. Their species-specific design offers the potential to reduce environmental risks and aim to be compatible and complementary with other control strategies, potentially expediting the elimination and eradication of malaria...

INTRODUCTION: The literature shows an optimistic landscape for the effectiveness of games in medical education. Nevertheless, games are not considered mainstream material in medical teaching. Two research questions that arise are the following: What pedagogical strategies do developers use when creating games for medical education? And what is the quality of the evidence on the effectiveness of games? METHODS: A systematic review was made by a multi-disciplinary team of researchers following the Cochrane Collaboration Guidelines...

The disulfide bond (-S-S-) is an enormously valuable functional group in a variety of chemical and biological agents that display effective reactivity or biological activities (e.g., antitumor activities). The disulfide bonds prevalent in proteins are somewhat oxidizing in the extracellular space; however, such disulfide bonds can rarely be found inside cells because of disulfide cleavage reactions facilitated by abundant free cellular thiols, including glutathione (GSH), which is the most important common thiol-containing small molecule...

Objectives In order to facilitate the study of vocalizations in emerging genetic common marmoset models of neurodegenerative disorders, we aimed to analyze call-type changes across age in a translational research environment. We hypothesized that acoustic parameters of vocalizations would change with age, reflecting growth of the vocal apparatus and a maturation of control needed to make adult-like calls. Methods Nineteen developing common marmosets were longitudinally video- and audio-recorded between the ages of 1-149 days in a naturalistic setting without any vocalization elicitation protocol...

Jessica Matov, Fiona Mensah, Fallon Cook, Sheena Reilly
BACKGROUND: The inaccurate estimation of language difficulties by teachers suggests the benefit of a short-language measure that could be used to support their decisions about who requires referral to a speech-language therapist. While the literature indicates the potential for the development of a short-language measure, evidence is lacking about which combination of language tasks it should include. AIMS: To understand the number and nature of components/language tasks that should be included in a short-language measure for children in the early school years...

Tuberculosis (TB) remains a devastating disease, yet despite its enormous toll on global health, tools to control TB are insufficient and often outdated. TB Biomarkers (TB-BM) would constitute extremely useful tools to measure infection status and predict outcome of infection, vaccination or therapy. There are several types of TB-BM: Correlate of Infection; Correlate of TB Disease; Correlate of Increased Risk of Developing Active TB Disease; Correlate of the Curative Response to Therapy; and Correlate of Protection (CoP)...

Near-infrared (NIR) light is widely used for noninvasive optical diagnosis and phototherapy. However, current research focuses on the first NIR window (NIR-I, 650-950 nm), while the second NIR window (NIR-II, 1000-1700 nm) is far less exploited. The development of the first organic photothermal nanoagent (SPNI-II ) with dual-peak absorption in both NIR windows and its utilization in photothermal therapy (PTT) are reported herein. Such a nanoagent comprises a semiconducting copolymer with two distinct segments that respectively and identically absorb NIR light at 808 and 1064 nm...

Children and young people are seen as fundamental to the design and delivery of clinical research as active and reflective participants. In Europe, involvement of children and young people in clinical research is promoted extensively in order to engage young people in research as partners and to give them a voice to raise their own issues or opinions and for their involvement in planning and decision making in addition to learning research skills. Children and young people can be trained in clinical research through participation in young person advisory groups (YPAGs)...

New techniques for the genetic modification of organisms are creating new strategies for addressing persistent public health challenges. For example, the company Oxitec has conducted field trials internationally-and has attempted to conduct field trials in the United States-of a genetically modified mosquito that can be used to control dengue, Zika, and some other mosquito-borne diseases. In 2016, a report commissioned by the National Academies of Sciences, Engineering, and Medicine discussed the potential benefits and risks of another strategy, using gene drives...

The recovery of people with psychiatric disabilities requires high-quality nursing care. However, the existing research on the nursing competencies needed for caring for people with psychiatric disabilities have been based on a narrow competency framework. By adopting a broader competency framework, this study aimed to find the competencies needed for the nursing care of people with psychiatric disabilities in a hospital environment. Accordingly, a questionnaire will be developed to measure these competences...
