BACKGROUND: Executive Functioning (EF) is an important factor for community functioning for people with severe mental illness. Cognitive remediation programs often improve EF, but do so by using multiple therapeutic techniques. Little is known regarding how individual treatment elements promote cognitive improvement. Oscillatory brain activity is a potential neurophysiological mechanism that may change as a result of targeted training on computerized exercises. The current study aimed to examine the effects of a brief EF training program on EEG and neurocognitive measures...

The receptor tyrosine kinase c-Met plays critical roles in promoting tumor growth, invasion, metastasis, and angiogenesis in various types of cancer and is a promising therapeutic target. The development of a species cross-reactive therapeutic antibody could provide useful to comprehensive preclinical assessment in animal models. Towards this goal, we developed human/mouse cross-reactive c-Met antibodies using an antibody phage library. IRCR201, a c-Met antibody with species cross-reactivity, successfully inhibited the HGF/c-Met signaling pathway via degradation of c-Met and disruption of the binding with its partners, and demonstrated strong in vivo antitumor activity...

The C - X - C chemokine receptor 4 (CXCR4) and its natural ligand CXCL12 are key factors in the process of cell migration, homing of hematopoietic stem cells to the bone marrow, and represent important mediators of angiogenesis and cell proliferation. The CXCR4/CXCL12 interplay can be disrupted by CXCR4 antagonists such as Plerixafor which are already in daily clinical use, i.e. for mobilization and subsequent harvesting of hematopoietic progenitor cells and stem cell transplantation. In a pathological condition, involvement in the process of metastasis and homing of cancer cells to a protective niche has been described, making CXCR4 an attractive target for imaging and treatment of malignant diseases...

The human gut is home to trillions of bacteria and provides the scaffold for one of the most complex microbial ecosystems in nature. Inflammatory bowel diseases, such as Crohn's disease, involve a compositional shift in the microbial constituents of this ecosystem with a marked expansion of Enterobacteriaceae, particularly Escherichia coli. Adherent-invasive E. coli (AIEC) strains are frequently isolated from the biopsies of Crohn's patients, where their ability to elicit inflammation suggests a possible role in Crohn's pathology...

Background: Significant adverse events (AE) during cancer therapy disrupt treatment and escalate to emergency admissions. Approaches to improve the timeliness and accuracy of AE reporting may improve safety and reduce health service costs. Reporting AE via patient reported outcomes (PROs), can improve clinician-patient communication and making data available to clinicians in 'real-time' using electronic PROs (ePROs) could potentially transform clinical practice by providing easily accessible records to guide treatment decisions...

BACKGROUND: With decreasing costs of GPS telemetry devices, data repositories of animal movement paths are increasing almost exponentially in size. A series of complex statistical tools have been developed in conjunction with this increase in data. Each of these methods offers certain improvements over previously proposed methods, but each has certain assumptions or shortcomings that make its general application difficult. In the case of the recently developed Time Local Convex Hull (T-LoCoH) method, the subjectivity in parameter selection serves as one of the primary impediments to its more widespread use...
