It is not surprising to find microbiome abnormalities present in psychiatric disorders such as depressive disorders, bipolar disorders, etc. Evolutionary pressure may provide an existential advantage to the host eukaryotic cells in that it survives in an extracellular environment containing non-self cells (e.g., bacteria). This phenomenon is both positive and negative, as with other intercellular processes. In this specific case, the phenomenal amount of information gained from combined bacterial genome could enhance communication between self and non-self cells...

During the 2014-15 Ebola outbreak in West Africa, the United States responded by stratifying hospitals into 1 of 3 Centers for Disease Control and Prevention (CDC)-designated categories-based on the hospital's ability to identify, isolate, assess, and provide care to patients with suspected or confirmed Ebola virus disease (EVD)-in an attempt to position the US healthcare system to safely isolate and care for potential patients. Now, with the Ebola epidemic quelled, it is crucial that we act on the lessons learned from the EVD response to broaden our national perspective on infectious disease mitigation and management, build on our newly enhanced healthcare capabilities to respond to infectious disease threats, develop a more cost-effective and sustainable model of infectious disease prevention, and continue to foster training so that the nation is not in a vulnerable position once more...

Although autobiographical memory and episodic simulations recruit similar core brain regions, episodic simulations engage additional neural recruitment in the frontoparietal control network due to greater demands on constructive processes. However, previous functional neuroimaging studies showing differences in remembering and episodic simulation have focused on veridical retrieval of past experiences, and thus have not fully considered how retrieving the past in different ways from how it was originally experienced may also place similar demands on constructive processes...

Background: While autism and attention-deficit/hyperactivity disorder (ADHD) are considered distinct conditions from a diagnostic perspective, clinically they share some phenotypic features and have high comorbidity. Regardless, most studies have focused on only one condition, with considerable heterogeneity in their results. Taking a dual-condition approach might help elucidate shared and distinct neural characteristics. Method: Graph theory was used to analyse topological properties of structural covariance networks across both conditions and relative to a neurotypical (NT; n = 87) group using data from the ABIDE (autism; n = 62) and ADHD-200 datasets (ADHD; n = 69)...

Rapid advances in Ca(2+) imaging techniques enable us to simultaneously monitor the activities of hundreds of astrocytes in the intact brain, thus providing a powerful tool for understanding the functions of both host and engrafted astrocytes in sensory processing in vivo. These techniques include both improved Ca(2+) indicators and advanced optical recording methods. Astrocytes in multiple cortical and sub-cortical areas are able to respond to the corresponding sensory modalities. These sensory stimuli produce astrocytic Ca(2+) responses through different cellular mechanisms...

INTRODUCTION: In order to ensure high-quality treatment for patients with cancer it is vital to implement organisational models (pathways and networks) and that guarantee continuity of care. Appropriate assessment tools that promote the evaluation and analysis of care pathways from the patients' perspective are available. Hence the aim of this study was to verify whether or not the coordination between the various stages and care providers in a cancer treatment pathway is perceived by our patients...

Renal tubular transport mechanisms are optimized to be energy efficient and tailored to local gradients and transport rates. The combined transcellular action of ion channels, transporters, and pumps, together with the paracellular pathway, enables kidney function. Monogenetic diseases and mouse models indicate that both trans- and paracellular proteins can become disease-causing candidates and may be targets for future therapeutic approaches. Recent advances in tight junction research have provided new insights into their structure, function, and regulation...

Nature has inspired mankind to create novel inventions with biomimetic structures and materials, where plants provide a significant source of inspiration. Plants have evolved a range of effective appendages, among which trichomes have attracted extensive research interest due to their enormous functions. It is important to understand trichome functions and corresponding mechanisms for their bioinspired applications. In this review, we provide a comprehensive overview of the diverse functions of trichomes, with emphasis placed upon their roles as biophysical barriers that can create a complex three-dimensional (3D) network to help the plant adapt to severe environments...

As a newly emerging environmental contaminant, tributyl phosphate (TBP) is of increasing concern because of the environmental problems it can cause. Studies have suggested that TBP induces hepatocellular adenomas and has malignant potential for hepatocellular carcinoma. However, the mechanisms of its adverse effects are unclear. In this study, metabonomic techniques were used to identify differential endogenous metabolites, draw network metabolic pathways and conduct network analysis to elucidate the underlying mechanisms involved in TBP induced pathological changes of the liver...

Iron is an essential trace element ensuring many functions in the body. However, excess iron can be toxic with deleterious consequences on function and tissue integrity. The understanding of the molecular and cellular mechanisms allowing iron level to be kept at physiological concentration has greatly progressed in recent years, in particular with the identification of the iron-regulatory hormone, hepcidin and its receptor ferroportin, the sole iron exporter known to date. This discovery has improved our ability to diagnose and manage iron disorders and offered new therapeutic perspectives for an important class of human diseases...

Although the specialized literature on the etiology of alexithymia is controversial, neurobiological research has shown relevant advances. The aim of this review is to analyze the available evidence regarding the neurophysiological bases of alexithymia. A comprehensive review of available articles from Medline/PubMed, EBSCO and SciELO was conducted. Previously, alexithymia was linked to a reduced interhemispheric brain connection. From a childhood traumatic perspective, the right prefrontal cortex and the default mode network would experience alterations, first hypermetabolic (dopaminergic and glutamatergic dysregulation) and then hypometabolic-dissociative (serotonergic and opioid dysregulation), resulting in a distorted interoceptive and emotional awareness...

The inner ear is composed of a complex mixture of cells, which together allow organisms to hear and maintain balance. The cells in the inner ear, which undergo an extraordinary process of development, have only recently begun to be studied on an individual level. As it has recently become clear that individual cells, previously considered to be of uniform character, may differ dramatically from each other, the need to study cell-to-cell variation, along with distinct transcriptional and regulatory signatures, has taken hold in the scientific community...

Pediatric hypertension is a risk for adult cardiovascular disease, making early detection important. The prevalence of pediatric essential hypertension is rising due to the increased prevalence of obesity. Though guidelines for screening, diagnosis, evaluation, and management are available, there are barriers to accurate diagnosis of pediatric hypertension, including lack of knowledge and complexity of blood pressure standards. We aimed to gain insights into reasons for low rates of diagnosis and treatment from primary care providers...

Tingting Cheng, Xianquan Zhan
Predictive, preventive, and personalized medicine (PPPM) is the hot spot and future direction in the field of cancer. Cancer is a complex, whole-body disease that involved multi-factors, multi-processes, and multi-consequences. A series of molecular alterations at different levels of genes (genome), RNAs (transcriptome), proteins (proteome), peptides (peptidome), metabolites (metabolome), and imaging characteristics (radiome) that resulted from exogenous and endogenous carcinogens are involved in tumorigenesis and mutually associate and function in a network system, thus determines the difficulty in the use of a single molecule as biomarker for personalized prediction, prevention, diagnosis, and treatment for cancer...

Advances in neuroimaging have greatly improved our understanding of human sleep from a systems neuroscience perspective. However, cognition and awareness are reduced during sleep, hindering the applicability of standard task-based paradigms. Methods recently developed to study spontaneous brain activity fluctuations have proven useful to overcome this limitation. In this review, we focus on the concept of functional connectivity (FC, i.e. statistical covariance between brain activity signals) and its application to functional magnetic resonance imaging (fMRI) data acquired during sleep...

The social communication impairments defining autism spectrum disorders (ASD) may be built upon core deficits in perspective-taking, language processing, and self-other representation. Self-referential processing entails the ability to incorporate self-awareness, self-judgment, and self-memory in information processing. Very few studies have examined the neural bases of integrating self-other representation and semantic processing in individuals with ASD. The main objective of this functional MRI study is to examine the role of language and social brain networks in self-other processing in young adults with ASD...

B-cell lymphomas are composed of tumor cells and the tumor microenvironment, which is conventionally thought to be composed of a mixture of stromal cells, blood vessels, immune cells, and non-cell components, such as extracellular matrix, cytokines, and chemokines. Exosomes, small endocytically derived vesicles that have been proved to be present in a variety of tumor niches and involved in mediating cell signaling networks, are increasingly regarded as important components of tumor microenvironment. In this review, we first focus on the biogenesis, biodistribution, transportation, and other general characteristics of exosomes and then highlight the vital roles of exosomes in lymphomagenesis and disease progression, particularly from the perspective of immune dysfunction, virus infection, and therapeutic resistance mechanisms...
