#1
Dongjun He, Ce Mo, Fang Fang
Saccadic eye movements cause rapid and dramatic displacements of the retinal image of the visual world, yet our conscious perception of the world remains stable and continuous. A popular explanation for this remarkable ability of our visual system to compensate for the displacements is the predictive feature remapping theory. The theory proposes that, before saccades, the representation of a visual stimulus can be predictively transferred from neurons that initially encode the stimulus to neurons whose receptive fields will encompass the stimulus location after the saccade...

Although much is known about volitional and reflexive smooth eye movements individually, much less is known about how they are coordinated. It is hypothesized that separate cortico-ponto-cerebellar loops subserve these different types of smooth eye movements. Specifically, the MT-MST-DLPN pathway is thought to be critical for ocular following eye movements, whereas the FEF-NRTP pathway is understood to be vital for volitional smooth pursuit. However, the role that these loops play in combined volitional and reflexive behavior is unknown...

This paper examines the role of the Technical Advisory Committee for antiretroviral therapy of the Brazilian AIDS program in mediating the decision-making process of including new antiretroviral (ARV) drugs in the Unified Health System services by the end of the 2000s. We conducted documental analysis and interviews with key informants from the governmental sphere and professionals. The work features the Technical Advisory Committee as an "expert community", defined as a network of individuals with expertise and competence in a particular sphere and whose knowledge is relevant in critical public policy decision areas...

Decision support for nutrient application remains an enigma if based on soil nutrient analysis. If the crop could be used as an auxiliary indicator, the plant nutrient status during different growth stages could complement the soil test, improving the fertilizer recommendation. Nutrient absorption and partitioning in the plant are here studied and described with mathematical models. The objective of this study considers the temporal variation of the nutrient uptake rate, which should define crop needs as compared to the critical content in soil solution...

We conducted a critical review of the literature on recurrent use of HIV testing in men who have sex with men (MSM). We performed a narrative review of the literature in which we analyzed the various conceptions on frequent testing over time, the implications for health programs, and the main social markers that influence the incorporation of HIV testing as routine care. Although it has existed since the 1990s, recurrent testing among MSM was frequently interpreted as increased exposure to HIV due to lack of condom use, and therefore as "unnecessary" testing...

Different facets of biodiversity other than species numbers are increasingly appreciated as critical for maintaining the function of ecosystems and their services to humans. While new international policy and assessment processes such as the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) recognize the importance of an increasingly global, quantitative and comprehensive approach to biodiversity protection, most insights are still focused on a single facet of biodiversity-species...

Bacteriophages are ubiquitous and numerous parasites of bacteria and play a critical evolutionary role in virtually every ecosystem, yet our understanding of the extent of the diversity and role of phages remains inadequate for many ecological niches, particularly in cases in which the host is unculturable. During the past 15 years, the emergence of the field of viral metagenomics has drastically enhanced our ability to analyse the so-called viral 'dark matter' of the biosphere. Here, we review the evolution of viral metagenomic methodologies, as well as providing an overview of some of the most significant applications and findings in this field of research...

The role of breastfeeding in improving allergy outcomes in early childhood is still unclear. Evidence suggests that immune mediators in human milk (HM) play a critical role in infant immune maturation as well as protection against atopy/allergy development. We investigated relationships between levels of immune mediators in colostrum and mature milk and infant outcomes in the first year of life. In a large prospective study of 398 pregnant/lactating women in the United Kingdom, Russia and Italy, colostrum and mature human milk (HM) samples were analysed for immune active molecules...

Breast cancer patients face challenges throughout the journey of diagnosis, treatment, post-treatment, and recovery. The breast cancer patient is exposed to a multidisciplinary team including doctors, nurses, therapists, counselors, and psychologists. While the team assembled together aims to address multiple facets in breast cancer care, the sub-specialized nature of individual professional practices may constrain the overview of patients' holistic needs and a comprehensive approach to cancer management. This paper aims to provide an overview of the holistic needs of breast cancer patients at each stage of their cancer journey, addressing their complex physical, psychological, and social needs...

Abstract: A number of abiotic and biotic factors are known to regulate arthropod attraction, colonization, and utilization of decomposing vertebrate remains. Such information is critical when assessing arthropod evidence associated with said remains in terms of forensic relevance. Interactions are not limited to just between the resource and arthropods. There is another biotic factor that has been historically overlooked; however, with the advent of high-throughput sequencing, and other molecular techniques, the curtain has been pulled back to reveal a microscopic world that is playing a major role with regards to carrion decomposition patterns in association with arthropods...

It is well established that the regulation of epigenetic factors, including chromatic reorganization, histone modifications, DNA methylation, and miRNA regulation, is critical for the normal development and functioning of the human brain. There are a number of maternal factors influencing epigenetic pathways such as lifestyle, including diet, alcohol consumption, and smoking, as well as age and infections (viral or bacterial). Genetic and metabolic alterations such as obesity, gestational diabetes mellitus (GDM), and thyroidism alter epigenetic mechanisms, thereby contributing to neurodevelopmental disorders (NDs) such as embryonic neural tube defects (NTDs), autism, Down's syndrome, Rett syndrome, and later onset of neuropsychological deficits...

INTRODUCTION: Trauma related hypotension and coagulopathy worsen secondary brain injury in patients with traumatic brain injuries (TBI). Early damage control resuscitation with blood products may mitigate hypotension and coagulopathy. Preliminary data suggest resuscitation with plasma in large animals improve neurologic function after TBI; however, data in humans are lacking. METHODS: We retrospectively identified all poly-trauma patients age >15 years with head injuries undergoing prehospital resuscitation with blood products at a single level I trauma center from 01/2002 to 12/2013...

BACKGROUND: Critical elements in intimate partner homicides (IPH) often go undocumented. Previous studies have highlighted precipitating causes, but few have examined the place of injury that led to the victim's death. We sought to describe IPH cases in Illinois, and in particular to examine factors surrounding the location of injury that led to the victim's death. METHODS: We analyzed data collected in the Illinois Violent Death Reporting System (IVDRS) to assess victim demographics, perpetrator characteristics, the victim/perpetrator relationship, and circumstances surrounding the location of injury that led to the victim's death...
