Introduction: KRAS and KRAS inhibitors represent a major translational breakthrough for non-small cell lung cancer (NSCLC) and cancer in general by directly targeting its most mutated oncoprotein. However, resistance to these small molecules has highlighted the need for rational combination partners necessitating a critical understanding of signaling downstream of KRAS mutant isoforms.
Methods: We contrasted tumor development between Kras and Kras genetically engineered mouse models (GEMMs).
Objective: CHD predisposes children to neurodevelopmental delays. Frequent, prolonged hospitalisations during infancy prevent children with heart disease from participating in recommended language and cognitive development programmes, such as outpatient early childhood literacy programmes, and contribute to caregiver stress, a risk factor for adverse developmental outcomes. This study aims to describe the implementation of a single-centre inpatient early childhood literacy programme for hospitalised infants with heart disease and assess its impact on reading practices and patient-family hospital experience.

However, individuals of color are underrepresented in dermatology-related medical information. We sought to gather information from women of color regarding their attitudes about the importance of the prevention of skin aging, available information, and perception of representation in skin-aging prevention information.

Currently, standards for skin care before, during, and after nonenergy and injectable treatments are lacking. The algorithm on supportive skin care for facial antiaging nonenergy and injectable treatments aims to stimulate healing, reduce downtime, and improve comfort and treatment outcomes.

Here, we show that the RAC1-selective guanine nucleotide exchange factor T cell invasion and metastasis-inducing protein 1 (TIAM1) promotes cell migration and invasion in the most common subtype of lung cancer, non-small-cell lung cancer (NSCLC), through an unexpected nuclear function.

We developed two-dimensional (2D) polyacrylamide (PAA) and three-dimensional (3D) alginate in vitro models of tissue stiffness that mimic the stiffness of normal breast and breast cancer. We then used these to compare cell viability in response to chemotherapeutic treatment.

Chemotherapy and targeted therapies have significantly improved patients' prognosis. Nevertheless, after a successful initial response, some patients relapse when cancer cells become resistant to drug treatments, representing an important clinical limitation.
View Article and Find Full Text PDFLung cancer is associated with a high mortality, with around 1.8 million deaths worldwide in 2018. Non-small-cell lung cancer (NSCLC) accounts for around 85% of cases and, despite improvement in the management of NSCLC, most patients are diagnosed at advanced stage and the five-year survival remains around 15%.

Method: In a one-group, repeated-measures, alternating-treatment design, the effectiveness of nurses' abilities to position neonates in the context of developmentally supportive care before and after different education approaches was scored using an instrument designed for this study. A self-administered survey was conducted with nurses to examine perceptions of positioning-related issues.
Magn Reson Imaging
February 1999
Magnetic resonance (MR) imaging has been suggested as a technique for diagnosing and monitoring myositis, an inflammatory muscle disease. To date, the assessment of disease from MR images has been by subjective visual analysis. We describe here an objective, semi-automatic, computer-based method for quantifying the degree of disease from MR images, without the need for a radiologist or physician trained in the visual assessment of the MR images.

Methods: We evaluated, in a prospective case-control study, consecutive patients with IIM who were referred to our center and ascertained without regard to family history or known risk factors for autoimmunity, and all available family members. We used a standardized assessment to determine the presence and type of autoimmune disease in each subject.
