Dasatinib-induced colitis in a patient with chronic myeloid leukaemia.

Dasatinib is a common treatment for chronic myeloid leukaemia with numerous side effects including gastrointestinal. We report a woman in her 50s who presented with haematochezia, weight loss and a positive faecal occult blood test. She was being treated for chronic myeloid leukaemia with dasatinib without the use of any concurrent medications, including non-steroidal anti-inflammatory drugs.

Photonic Inks with Dual-Layer Security Features by Encapsulation of Color Tunable Fluorescent Dyes in PMMA Colloidal Microspheres.

To counter economic terrorism by preventing counterfeit currency, documents and high-value commercial products, new-generation security inks with multiple safety features are required. Herein, color-tunable pyrylium and pyridinium dye-encapsulated polymethyl methacrylate (PMMA) colloidal microspheres are reported to exhibiting brilliant emission and photonic properties. A combination of the PMMA colloidal photonic ink having structural color variation and the dye-encapsulated colloidal photonic ink with fluorescence modulation is used for security labeling.

Layer-number-dependent photoswitchability in 2D MoS-diarylethene hybrids.

Molybdenum disulfide (MoS) is a notable two-dimensional (2D) transition metal dichalcogenide (TMD) with properties ideal for nanoelectronic and optoelectronic applications. With growing interest in the material, it is critical to understand its layer-number-dependent properties and develop strategies for controlling them. Here, we demonstrate a photo-modulation of MoS flakes and elucidate layer-number-dependent charge transfer behaviors.

Management of Neonatal Hyperinsulinemic Hypoglycemia: Trends Over Nine Years.

Background: With increasing use of diazoxide for hyperinsulinemic hypoglycemia (HH), reporting of serious side effects of diazoxide such as pulmonary hypertension (PHT) increased.

Methods: Charts of all children diagnosed with HH during the study period and evaluated by Pediatric Endocrinology division of the Hasbro Children's Hospital were reviewed. We analyzed diazoxide use among infants with HH with focus on infants born small for gestational age (SGA) and preterm infants.

Folate prevents the autism-related phenotype caused by developmental pyrethroid exposure in prairie voles.

Neurodevelopmental disorders (NDDs) have dramatically increased in prevalence to an alarming one in six children, and yet both causes and preventions remain elusive. Recent human epidemiology and animal studies have implicated developmental exposure to pyrethroid pesticides, one of the most common classes of pesticides in the US, as an environmental risk factor for autism and neurodevelopmental disorders. Our previous research has shown that low-dose chronic developmental pyrethroid exposure (DPE) changes folate metabolites in the adult mouse brain.
