Cystic fibrosis (CF) is the most common life-shortening genetic disease affecting approximately 1 in 3500 of the Caucasian population. CF is caused by mutations in the CF transmembrane conductance regulator (CFTR) gene. To date, over 2000 CFTR mutations have been identified and produce a wide range of phenotypes. The CFTR protein, a chloride channel, is normally expressed on epithelial cells lining the lung, gut, and exocrine glands. Mutations in CFTR have led to pleiotropic effects in CF patients and have resulted in early morbidity and mortality...

There is a large amount of information in brightfield images that was previously inaccessible by using traditional microscopy techniques. This information can now be exploited by using machine-learning approaches for both image segmentation and the classification of objects. We have combined these approaches with a label-free assay for growth and differentiation of leukemic colonies, to generate a novel platform for phenotypic drug discovery. Initially, a supervised machine-learning algorithm was used to identify in-focus colonies growing in a three-dimensional (3D) methylcellulose gel...

CD19-targeted chimeric antigen receptor (CAR) engineered T/natural kill (NK)-cell therapies can result in durable clinical responses in B-cell malignancies. However, CAR-based immunotherapies have been much less successful in solid cancers, in part due to 'on-target off-tumor' toxicity related to expression of target tumor antigens on normal tissue. Based on preliminary observations of safety and clinical activity in proof-of-concept clinical trials, tumor antigen-specific messenger RNA (mRNA) CAR transfection into selected, activated, and expanded T/NK-cells may permit prospective control of 'on-target off-tumor toxicity'...

INTRODUCTION: The therapeutic techniques used in the fascial distortion model (FDM) have become increasingly popular among manual therapists and physical therapists. The reasons for this trend remain to be empirically explored. Therefore this paper pursues two goals: first, to investigate the historical and theoretical background of FDM, and second, to discuss seven problems associated with the theory and practice of FDM. MATERIALS AND METHODS: The objectives of this paper are based on a review of the literature...

REVIEW
Ayşe Öner
Hereditary retinal dystrophies (HRDs) are degenerative diseases of the retina which have marked clinical and genetic heterogeneity. Common presentations among these disorders include night or colour blindness, tunnel vision, and subsequent progression to complete blindness. The known causative disease genes have a variety of developmental and functional roles, with mutations in more than 120 genes shown to be responsible for the phenotypes. In addition, mutations within the same gene have been shown to cause different disease phenotypes, even amongst affected individuals within the same family, highlighting further levels of complexity...

The development of CAR T cells currently represents an exciting opportunity to convert the already published clinical successes observed in clinical trials into commercially available efficient therapies. However, the path toward successful commercialization is still hindered by many hurdles. Here, we review such issues as: the need for structured collaborations between hospital collection and clinical facilities and industry manufacturing facilities to streamline the supply chain; necessity for uniform and efficient medical procedures to cope with severe toxicities associated with CAR T cells; and absolute need to define an economical and sustainable model for manufacturers and payers...

Surgery is often the first treatment option for patients with cancer. Patient survival essentially depends on the completeness of tumor resection. This is a major challenge, particularly in cases of peritoneal carcinomatosis, where tumors are widely disseminated in the large peritoneal cavity. Any development to help surgeons visualize these residual cells would improve the completeness of the surgery. For non-disseminated tumors, imaging could be used to ensure that the tumor margins and the draining lymph nodes are free of tumor deposits...

Multiple therapeutic options exist for multiple myeloma (MM), including autologous hematopoietic stem cell transplantation (AHSCT). Measurement of minimal residual disease (MRD) and immune reconstitution is rapidly becoming an integral part of the care of MM patients. We investigated comprehensive immune profiling (IP) associated with progression-free survival (PFS) and overall survival (OS). From August 2007 to January 2014, 101 consecutive MM patients underwent peripheral blood IP and marrow MRD testing before and approximately 100 days after AHSCT...

The aminosteroid derivative RM-133 is an effective anticancer molecule for which proof of concept has been achieved in several mouse xenograph models (HL-60, MCF-7, PANC-1 and OVCAR-3). To promote this new family of molecules toward a clinical phase 1 trial, the mechanism of action governing the anticancer properties of the representative candidate RM-133 needs to be characterized. In vitro experiments were first used to determine that RM-133 causes apoptosis in cancer cells. Then, using proteomic and transcriptomic experiments, RM-133 cytotoxicity was proven to be achieved via the endoplasmic reticulum (ER)-related apoptosis, which characterizes RM-133 as an endoplasmic reticulum stress aggravator (ERSA) anticancer drug...

Visual impairment caused by retinal degeneration is primarily attributed to the irreversible degradation of retinal neurons or the adjacent retinal pigment epithelium (RPE). No efficient clinical therapies to restore or improve visual ability are currently available. Cell therapy has been touted as a promising strategy to overcome this challenge. Progenitor/stem cells may be obtained from both ocular and non-ocular tissues. The former mainly includes retinal progenitor cells (RPCs), whereas the latter comprises embryonic stem cells (ESCs) and induced pluripotent stem cells (iPSCs), which have been utilized in stem cell replacement therapy studies ranging from proof-of-concept animal models to clinical trials in humans...

OBJECTIVE: To investigate efficacy, patient acceptability and feasibility of formulation-based cognitive-behavioural therapy (CBT) for adults with attention-deficit hyperactivity disorder (ADHD). NICE guidelines for adult ADHD recommend further research into psychological treatments. METHOD: Sixty participants with adult ADHD were randomly allocated to treatment as usual (TAU) vs. TAU plus up to 16 sessions of individual formulation-based CBT for ADHD. RESULTS: Adding formulation-based CBT to TAU for ADHD significantly improved ADHD symptoms on the Barkley Current Symptoms Scale and scores on the Work and Social Adjustment Scale...

OBJECTIVE: Interleukin (IL)-17A has emerged as pivotal in driving tissue pathology in immune-mediated inflammatory diseases. The role of IL-17F, sharing 50% sequence homology and overlapping biological function, remains less clear. We hypothesised that IL-17F, together with IL-17A, contributes to chronic tissue inflammation, and that dual neutralisation may lead to more profound suppression of inflammation than inhibition of IL-17A alone. METHODS: Preclinical experiments assessed the role of IL-17A and IL-17F in tissue inflammation using disease-relevant human cells...

BACKGROUND: Many patients with diabetes require insulin therapy to achieve optimal glycemic control. Initiation and titration of insulin often require an insulin dose adjustment (IDA) program, involving frequent exchange of blood glucose levels (BGLs) and insulin prescription advice between the patient and healthcare team. This process is time consuming with logistical barriers. OBJECTIVE: To develop an innovative mobile health (m-Health) mobile-based IDA program (mIDA) and evaluate the user adherence and experience through a proof-of-concept trial...

OBJECTIVES: Social anxiety disorder (SAD) is one of the most common psychiatric disorders in youth, with a prevalence of about 3%-4% and increased risk of adverse long-term outcomes, such as depression. Cognitive-behavioural therapy (CBT) is considered the first-line treatment for youth with SAD, but many adolescents remain untreated due to limited accessibility to CBT. The aim of this study was to develop and evaluate the feasibility and preliminary efficacy of a therapist-guided internet-delivered CBT treatment, supplemented with clinic-based group exposure sessions (BIP SOFT)...

The need for new and effective treatments for dementia remains indisputably high. Phosphodiesterase inhibitors (PDE-Is) have proven efficacy as cognitive enhancers based on their positive effects in numerous preclinical studies. Especially the PDE4 subfamily is of interest due to its expression in the hippocampus, the key structure for memory formation. The current study investigates the memory enhancing effects of the clinically approved PDE4-I roflumilast in a test battery including the Verbal Learning Task (VLT) combined with electroencephalography (EEG) recording...

Paclitaxel and carboplatin combination chemotherapy has remained the standard of care in the front-line therapy of advanced epithelial ovarian cancer during the last decade. Maintenance chemotherapy has not been proven to impact on overall survival. Acceptable alternatives include weekly paclitaxel plus 3-weekly carboplatin, the addition of bevacizumab to 3-weekly carboplatin and paclitaxel, and intraperitoneal chemotherapy. In particular, anti-angiogenic therapy has been identified as the most promising targeted therapy, and the addition of bevacizumab to first-line chemotherapy followed by a maintenance period of bevacizumab in monotherapy has shown to prolong progression-free survival...

A single pot dipolar cycloaddition reaction / Cope elimination sequence was developed to access novel 1,4,6,7-tetrahydro-5H-[1,2,3]triazolo[4,5-c]pyridine P2X7 antagonists that contain a synthetically challenging chiral center. The structure-activity relationships of the new compounds are described. Two of these compounds, (S)-(2-fluoro-3-(trifluoromethyl)phenyl)(1-(5-fluoropyrimidin-2-yl)-6-methyl-1,4,6,7-tetrahydro-5H-[1,2,3]triazolo[4,5-c]pyridin-5-yl)methanone (compound 14) and (S)-(3-fluoro-2-(trifluoromethyl)pyridin-4-yl)(1-(5-fluoropyrimidin-2-yl)-6-methyl-1,4,6,7-tetrahydro-5H-[1,2,3]triazolo[4,5-c]pyridin-5-yl)methanone (compound 20), were found to have robust P2X7 receptor occupancy at low doses in rat with ED50 values of 0...

Traditional cell culture and animal models utilized for preclinical drug screening have led to high attrition rates of drug candidates in clinical trials due to their low predictive power for human response. Alternative models using human cells to build in vitro biomimetics of the human body with physiologically relevant organ-organ interactions hold great potential to act as "human surrogates" and provide more accurate prediction of drug effects in humans. This review is a comprehensive investigation into the development of tissue-engineered human cell-based microscale multiorgan models, or multiorgan microphysiological systems for drug testing...
