The recent significant breakthroughs in the understanding of the pathogenetic mechanisms of psoriasis and other immune-mediated inflammatory disorders, have led to the emergence of a wide array of biologic agents or biologics, that are especially designed to target selective intracellular or extracellular components and pathways of the dysregulated immune response. These targeted biologic agents have altered the landscape in dermatotherapy aiming to offer higher therapeutic efficacy and an alternative in patients who either failed on conventional systemic regimens or have no other therapeutic options...

Chromatin immunoprecipitation followed by massively parallel sequencing (ChIP-seq) is a powerful technology to profile genome-wide chromatin modification patterns and is increasingly being used to study the molecular mechanisms of brain diseases such as drug addiction. This protocol discusses the typical procedures involved in ChIP-seq data generation, bioinformatic analysis, and interpretation of results, using a chronic cocaine treatment study as a template. We describe an experimental design that induces significant chromatin modifications in mouse brain, and the use of ChIP-seq to derive novel information about the chromatin regulatory mechanisms involved...

In the past decade, the landscape of drug development in oncology has evolved dramatically; however, this paradigm shift remains to be adopted in early phase clinical trial designs for studies of molecularly targeted agents and immunotherapeutic agents in paediatric malignancies. In drug development, prioritization of drugs on the basis of knowledge of tumour biology, molecular 'drivers' of disease and a drug's mechanism of action, and therapeutic unmet needs are key elements; these aspects are relevant to early phase paediatric trials, in which molecular profiling is strongly encouraged...

Landscape approaches can be subjected to mistakenly targeting a single "best" level of governance, and paying too little attention to the role that cross-scale and cross-level interactions play in governance. In rangeland settings, resources, patterns of use of those resources, and the institutions for managing the resources exist at multiple levels and scales. While the scholarship on commons offers some guidance on how to conceptualize governance in rangeland landscapes, some elements of commons scholarship-notably the "design principles" for effective governance of commons-do not seem to apply neatly to governance in pastoralist rangeland settings...

Previous research has investigated ways to quantify visual information of a scene in terms of a visual processing hierarchy, i.e., making sense of visual environment by segmentation and integration of elementary sensory input. Guided by this research, studies have developed categories for low-level visual features (e.g., edges, colors), high-level visual features (scene-level entities that convey semantic information such as objects), and how models of those features predict aesthetic preference and naturalness...

OBJECTIVES: Cyclical submergence and re-emergence of the Sunda Shelf throughout the Pleistocene served as a dynamic biogeographic landscape, across which long-tailed macaques (Macaca fascicularis) have migrated and evolved. Here, we tested the integrity of the previously reported continental-insular haplotype divide reported among Y and mitochondrial DNA lineages across multiple studies. MATERIALS AND METHODS: The continental-insular haplotype divide was tested by heavily sampling wild macaques from two important biogeographic regions within Sundaland: (1) Singapore, the southernmost tip of continental Asia and (2) Bali, Indonesia, the southeastern edge of the Indonesian archipelago, immediately west of Wallace's line...

Process understanding for designing, optimizing and scaling of pharmaceutical unit operations is fundamentally important to address concerns of high risks, monumental costs, and productivity decline in the pharmaceutical industry. This is especially important in the rapidly changing landscape of the pharmaceutical industry. Pharmaceutical processes majorly deal with multiphase, multicomponent flows, basics of which are discussed in terms of fundamental contact and non-contact forces. Also, basics of multiphase flow regimes, powder flow, and pertinent process modeling techniques relevant to pharmaceutical unit operations are discussed...

The varied yet family-specific conformational pathways utilized by individual glycoside hydrolases (GHs) offer a tantalising prospect for the design of tight binding and specific enzyme inhibitors. A cardinal example of a GH family specific inhibitor, and one that finds widespread practical use, is the natural product kifunensine, which is a low nanomolar inhibitor selective for GH family 47 inverting a-mannosidases. Here we show, through quantum mechanical approaches, that kifunensine is restrained to a 'ring-flipped' 1C4 conformation with another accessible, but higher-energy, region around the 1,4B conformation...

Livestock farming is an essential activity in many rural areas, where it contributes to the maintenance of soil fertility and farmland biodiversity, as well as to a set of social public goods including food security, rural vitality and culture. However, livestock sustainability assessments tend to focus primarily on environmental and economic dimensions; therefore, these valuations might be limited because they do not consider the complete set of associated goods and services (GS). Hence, a need exists to recognise the multiple contributions provided by livestock to human well-being and society...

BACKGROUND: Ghana's socio-cultural landscape proscribes suicidal behaviour, and this has serious ramifications for attempt survivors and their families. The objective of this qualitative study was to understand the experiences of the families of attempt survivors and how they cope with the aftermath of the attempt. METHODS: Ten families with attempted suicides agreed to participate in the study, hence they were interviewed. The information gathered was manually analyzed according to Interpretative Phenomenological Analysis (IPA) resulting in three major thematic areas...

Formation of 3D mesostructures in advanced functional materials is of growing interest due to the widespread envisioned applications of devices that exploit 3D architectures. Mechanically guided assembly based on compressive buckling of 2D precursors represents a promising method, with applicability to a diverse set of geometries and materials, including inorganic semiconductors, metals, polymers, and their heterogeneous combinations. This paper introduces ideas that extend the levels of control and the range of 3D layouts that are achievable in this manner...

The potential energy landscape perspective provides both a conceptual and a computational framework for predicting, understanding and designing molecular properties. In this Feature Article, we highlight some recent advances that greatly facilitate structure prediction and analysis of global thermodynamics and kinetics in proteins and nucleic acids. The geometry optimisation procedures, on which these calculations are based, can be accelerated significantly using local rigidification of selected degrees of freedom, and through implementations on graphics processing units...

An innovative strategy for electrostatically designing the electronic structure of 3D bulk materials is proposed to control charge carriers at the nanoscale. This is achieved by shifting the electronic levels of chemically identical semiconducting elements through the periodic arrangement of polar functional groups. For the example of covalent organic networks, by first-principles calculations, the resulting collective electrostatic effects are shown to allow a targeted manipulation of the electronic landscape such that spatially confined pathways for electrons and holes can be realized...

Bulk tissue stiffness has been correlated with regulation of cellular processes and conversely cells have been shown to remodel their pericellular tissue according to a complex feedback mechanism critical to development, homeostasis, and disease. However, bulk rheological methods mask the dynamics within a heterogeneous fibrous extracellular matrix (ECM) in the region proximal to a cell (pericellular region). Here, we use optical tweezers active microrheology (AMR) to probe the distribution of the complex material response function (α = α' + α'', in units of µm/nN) within a type I collagen ECM, a biomaterial commonly used in tissue engineering...

As an important target for the development of novel antibiotics, UDP-3-O-(R-3-hydroxymyristoyl)-N-acetylglucosamine deacetylase (LpxC) has been widely studied. Pyridone methylsulfone hydroxamate (PMH) compounds can effectively inhibit the catalytic activity of LpxC. In this work, the three-dimensional quantitative structure-activity relationships of PMH inhibitors were explored and models with good predictive ability were established using comparative molecular field analysis and comparative molecular similarity index analysis methods...

Limited cellular uptake and inefficient intracellular drug release severely hamper the landscape of polymer drug nanocarriers in cancer chemotherapy. Herein, to address these urgent challenges in tumor treatment simultaneously, we integrated the multivalent choline phosphate (CP) and bioreducible linker into a single polymer chain, designed and synthesized a neoteric bioreducible polymer nanocarrier. The excellent hydrophility of these zwitterionic CP groups endowed high drug loading content and drug loading efficiency of doxorubicin to this drug delivery system (∼22...

To determine whether the mutational profile of primary cutaneous diffuse large B-cell lymphoma leg-type (PCLBCL-LT) is unique by comparison with other diffuse large B-cell lymphoma (DLBCL) subtypes, we analyzed a total cohort of 28 PCLBCL-LT cases by next generation sequencing with a Lymphopanel designed for DLBCL. We also analyzed 12 pairs of tumor and control DNA samples by whole exome sequencing which led us to perform resequencing of three selected genes not included in the Lymphopanel: TBL1XR1, KLHL6 and IKZF3...

To guide the design of immunotherapy strategies for patients with early stage lung tumors, we developed a multiscale immune profiling strategy to map the immune landscape of early lung adenocarcinoma lesions to search for tumor-driven immune changes. Utilizing a barcoding method that allows a simultaneous single-cell analysis of the tumor, non-involved lung, and blood cells, we provide a detailed immune cell atlas of early lung tumors. We show that stage I lung adenocarcinoma lesions already harbor significantly altered T cell and NK cell compartments...
