#1
Chuanling Zhang, Xueying Zhou, Tianzhuo Yao, Zhenyu Tian, Demin Zhou
Adeno-associated virus 2 (AAV2) is a common vehicle for the delivery of a variety of therapeutic genes. A better understanding of the process of infection of AAV2 will advance our knowledge of AAV2 biology and allow for the optimization of AAV2 capsids with favorable transduction profiles. However, the precise fluorescent labeling of an AAV2 vector for probing virus tracking without affecting the nature of the virus remains a challenge. In this study, we precisely displayed lab-synthesized azide-moieties on the viral capsid at modifiable sites...

Mallory King, Brian Sardella
Mozambique tilapia have been shown to be incredibly stress tolerant with respect to environmental salinity, hypoxia, and ammonia concentrations. Temperature challenges to this species have shown that they have difficulty with cold acclimation. The purpose of this study was to measure the effects of acclimation temperature and salinity on the thermal tolerance of Mozambique tilapia as assessed by critical thermal maxima (CTMax) and critical thermal minima (CTMin). We also monitored fish behavior and quantified ventilation rate...

REVIEW
Clement Bommier, Xiulei Ji
Through intense effort in recent years, knowledge of Na-ion batteries has been advanced significantly, pertaining to electrodes. Often, such progress has been accompanied by using a convenient choice of electrolyte or binder. Nevertheless, it has been witnessed that "external" factors to electrodes, such as electrolytes, solid electrolyte interphase, and binders, affect the functions of electrodes profoundly. And generally, certain types of electrodes favor some electrolytes or binders. With a rapidly increasing number of publications in the area, trends in terms of electrolytes and binders are possibly exploitable...

Joane S Elleouet, Sally N Aitken
Approximate Bayesian computation (ABC) is widely used to infer demographic history of populations and species using DNA markers. Genomic markers can now be developed for non-model species using reduced representation library (RRL) sequencing methods that select a fraction of the genome using targeted sequence capture or restriction enzymes (genotyping-by-sequencing, GBS). We explored the influence of marker number and length, knowledge of gametic phase, and tradeoffs between sample size and sequencing depth on the quality of demographic inferences performed with ABC...

The collection of very large text sources has revolutionized the study of natural language, leading to the development of several models of language learning and distributional semantics that extract sophisticated semantic representations of words based on the statistical redundancies contained within natural language (e.g., Griffiths, Steyvers, & Tenenbaum, ; Jones & Mewhort, ; Landauer & Dumais, ; Mikolov, Sutskever, Chen, Corrado, & Dean, ). The models treat knowledge as an interaction of processing mechanisms and the structure of language experience...

REVIEW
Kasturi Haldar, Souvik Bhattacharjee, Innocent Safeukui
A marked decrease in malaria-related deaths worldwide has been attributed to the administration of effective antimalarials against Plasmodium falciparum, in particular, artemisinin-based combination therapies (ACTs). Increasingly, ACTs are also used to treat Plasmodium vivax, the second major human malaria parasite. However, resistance to frontline artemisinins and partner drugs is now causing the failure of P. falciparum ACTs in southeast Asia. In this Review, we discuss our current knowledge of markers and mechanisms of resistance to artemisinins and ACTs...

PURPOSE: Viscoelastic tests (VETs), thromboelastography (TEG®) and thromboelastometry (ROTEM®) are global tests of coagulation performed on whole blood. They evaluate the mechanical strength of a clot as it builds and develops after coagulation itself. The time required to obtain haemostasis results remains a major problem for clinicians dealing with bleeding, although some teams have developed a rapid laboratory response strategy. Indeed, the value of rapid point-of-care diagnostic devices such as VETs has increased over the years...

OBJECTIVE: Using standards is not only useful for data interchange during the process of a clinical trial, but also useful for analyzing data in a review process. Any step, which speeds up approval of new drugs, may benefit patients. As a result, adopting standards for regulatory submission becomes mandatory in some countries. However, preparing standard-compliant documents, such as annotated case report form (aCRF), needs a great deal of knowledge and experience. The process is complex and labor-intensive...

Shuang Qu, Sibao Wang
Entomopathogenic fungi can invade wide range of insect hosts in the natural world and have been used as environmentally friendly alternatives to chemical insecticides for pest control. Studies of host-pathogen interactions provide valuable insights into the coevolutionay arms race between fungal pathogens and their hosts. Entomopathogenic fungi have evolved a series of sophisticated strategies to counter insect immune defenses. In response to fungal infection, insect hosts rely on behavior avoidance and innate defenses in the fight against invading pathogens, including the use of physical barriers and innate immune responses...

The oral microbiome plays a critical role in maintaining oral health. Frequent dietary carbohydrate intake can lead to dysbiosis of the microbial community from overproduction of acid with selection for increases in acidogenic, acid-tolerant bacteria. Knowledge of the caries-associated microbiome is key in planning approaches to reverse the dysbiosis to achieve health. For risk assessment and treatment studies, it would be valuable to establish whether microbial monitoring requires assay of multiple species or whether selected key species would suffice...

Haley E Kragness, Laurel J Trainor
Proper segmentation of auditory streams is essential for understanding music. Many cues, including meter, melodic contour, and harmony, influence adults' perception of musical phrase boundaries. To date, no studies have examined young children's musical grouping in a production task. We used a musical self-pacing method to investigate (1) whether dwell times index young children's musical phrase grouping and, if so, (2) whether children dwell longer on phrase boundaries defined by harmonic cues specifically...

Promoting trust in public officials and active political engagement is vital to sustaining a well-functioning democracy. Developmental psychologists propose that youths' beliefs about government and participation in politics are rooted in personal experiences within their communities. Previous studies have focused on how positive experiences within youths' families, schools, and communities facilitate greater social trust and political participation. However, less is known about how negative interpersonal experiences-such as criminal victimization-intersect with youths' beliefs about the trustworthiness, competence, and knowledge of government officials, and their participation in political activity...
