Our work focuses on the stability, resilience, and response to perturbation of the bacterial communities in the human gut. Informative flash flood-like disturbances that eliminate most gastrointestinal biomass can be induced using a clinically-relevant iso-osmotic agent. We designed and executed such a disturbance in human volunteers using a dense longitudinal sampling scheme extending before and after induced diarrhea. This experiment has enabled a careful multidomain analysis of a controlled perturbation of the human gut microbiota with a new level of resolution...

With the rapid development of nanotechnology as well as growing interest in immunotherapy, a great number of vaccine delivery vehicles have been explored in order to elicit potent adaptive immune responses against various infections or tumors. Recent studies have shown that targeting vaccine to antigen-presenting cells (APCs) within lymph nodes is an effective strategy for improving antigen-specific adaptive immune response. However, the characteristics of vaccine vehicles, such as size, surface charge and the degree of PEGylation, affect lymph node transfer and subsequent APC uptake, leading to different levels of immune responses...

BACKGROUND: VAR2CSA, a member of the Plasmodium falciparum erythrocyte membrane protein 1 (PfEMP1) family, mediates the binding of P. falciparum-infected erythrocytes to chondroitin sulfate A, a surface-associated molecule expressed in placental cells, and plays a central role in the pathogenesis of placental malaria. VAR2CSA is a target of naturally acquired immunity and, as such, is a leading vaccine candidate against placental malaria. This protein is very polymorphic and technically challenging to sequence...

Severe intestinal graft-vs-host disease (GVHD) after allogeneic hematopoietic cell transplantation (HCT) causes mucosal ulceration and induces innate and adaptive immune responses that amplify and perpetuate GVHD and the associated barrier dysfunction. Pharmacological agents to target mucosal barrier dysfunction in GVHD are needed. We hypothesized that induction of Wnt signaling by lithium, an inhibitor of glycogen synthase kinase (GSK3), would potentiate intestinal crypt proliferation and mucosal repair and that inhibition of GSK3 in inflammatory cells would attenuate the deregulated inflammatory response to mucosal injury...

In this contribution, a software system for computer-aided position planning of miniplates to treat facial bone defects is proposed. The intra-operatively used bone plates have to be passively adapted on the underlying bone contours for adequate bone fragment stabilization. However, this procedure can lead to frequent intra-operatively performed material readjustments especially in complex surgical cases. Our approach is able to fit a selection of common implant models on the surgeon's desired position in a 3D computer model...

As an important economic natural resource in Southeast Asia, reticulated pythons (Malayopython reticulatus ssp.) are primarily harvested from the wild for their skins-which are prized in the luxury leather goods industry. Trade dynamics of this CITES Appendix II listed species are complex and management approaches on the country or regional level appear obscure. Little is known about the actual geographic point-of-harvest of snakes, how genetic diversity is partitioned across the species range, how current harvest levels may affect the genetic viability of populations, and whether genetic structure could (or should) be accounted for when managing harvest quotas...

This article focuses on patient-reported and clinician-reported outcome measures in spine trauma care. The measurement of the quality of care and functional and health-related quality of life outcomes of spine trauma patients has become increasingly important. However, no outcome instrument is specifically designed, validated, or universally adapted for this specific patient population. Issues specific to spinal trauma patients may not be adequately addressed by the instruments that are currently used in the literature and the daily clinical practice...

REVIEW
Lucas Kempf, Jonathan C Goldsmith, Robert Temple
Rare disease drug development is a rapidly expanding field. Clinical researchers in rare diseases face many challenges when conducting trials in small populations. Disease natural history is often poorly understood and the ability to detect clinically meaningful outcomes requires understanding of their rate of occurrence and variability, both of which contribute to difficulties in powering a study. Standard trial designs are not optimized to obtain adequate safety and efficacy data from small numbers of patients, so alternative designs (enrichment, crossover, adaptive, N-of 1) need to be considered...

Zinc finger recombinases (ZFRs) are designer site-specific recombinases that have been adapted for a variety of genome editing purposes. Due to their modular nature, ZFRs can be customized for targeted sequence recognition and recombination. There has been substantial research on the in vivo properties and applications of ZFRs; however, in order to fully understand and customize them, it will be necessary to study their properties in vitro. Experiments in vitro can allow us to optimize catalytic activities, improve target specificity, measure and minimize off-target activity, and characterize key steps in the recombination pathway that might be modified to improve performance...

Modeling the dynamic nature of protein-ligand binding with atomistic simulations is one of the main challenges in computational biophysics, with important implications in the drug design process. Although in the past few years hardware and software advances have significantly revamped the use of molecular simulations, we still lack a fast and accurate ab initio description of the binding mechanism in complex systems, available only for up-to-date techniques and requiring several hours or days of heavy computation...

Glioblastoma (GBM) is a deadly disease with few effective therapies. While much has been learned about the molecular characteristics of the disease, this knowledge has not been translated into clinical improvements for patients. At the same time, many new therapies are being developed. Many of these therapies have potential biomarkers to identify responders. The result is an enormous amount of testable clinical questions that must be answered efficiently. The GBM Adaptive Global Innovative Learning Environment (GBM AGILE) is a novel, multi-arm, platform trial designed to address these challenges...

Brahim Brahmi, Maarouf Saad, Cristobal Ochoa-Luna, Mohammad H Rahman
In this paper, we propose a new adaptive control technique based on nonlinear sliding mode control (JSTDE) taking into account kinematics and dynamics uncertainties. This approach is applied to an exoskeleton robot with uncertain kinematics and dynamics. The adaptation design is based on Time Delay Estimation (TDE). The proposed strategy does not necessitate the well-defined dynamic and kinematic models of the system robot. The updated laws are designed using Lyapunov-function to solve the adaptation problem systematically, proving the close loop stability and ensuring the convergence asymptotically of the outputs tracking errors...

Kinematic compatibility is of paramount importance in wearable robotic and exoskeleton design. Misalignments between exoskeletons and anatomical joints of the human body result in interaction forces which make wearing the exoskeleton uncomfortable and even dangerous for the human. In this paper we present a kinematically compatible design of an exoskeleton hip to reduce kinematic incompatibilities, so called macro- and micro-misalignments, between the human's and exoskeleton's joint axes, which are caused by inter-subject variability and articulation...
