REVIEW
Wen-Zhao Zhong, Qing Zhou, Yi-Long Wu
Epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKI) have been established as the standard therapy for EGFR-sensitizing mutant advanced non-small-cell lung cancer (NSCLC). However, patients ultimately develop resistance to these drugs. There are several mechanisms of both primary and secondary resistance to EGFR-TKIs. The primary resistance mechanisms include point mutations in exon 18, deletions or insertions in exon 19, insertions, duplications and point mutations in exon 20 and point mutation in exon 21 of EGFR gene...

Renal dysfunction is among the most common complication of sickle cell disease (SCD), from hyposthenuria in children to progression to overt chronic kidney disease (CKD) in young adults. Emerging evidence now suggests that sickle hemoglobin-related nephropathy extends to individuals with sickle cell trait (SCT). Areas covered: This review will highlight the pathophysiology, epidemiology, and management recommendations for sickle nephropathy in both SCD and SCT. In addition, it will focus on the major demographic and genetic modifiers of renal disease in sickling hemoglobinopathies...

REVIEW
Albert Farre, Janet E McDonagh
The transition to adult healthcare has been the subject of increased research and policy attention over many years. However, unmet needs of adolescent and young adults (AYAs) and their families continue to be documented, and universal implementation has yet to be realised. Therefore, it is pertinent to re-examine health transition in light of the principles of adolescent medicine from which it emerged, and consider this particular life transition in terms of a developmental milestone rather than a negotiation of structural boundaries between child and adult services...

Although a plurality of drugs target G-protein-coupled receptors (GPCRs), most have emerged from classical medicinal chemistry and pharmacology programs and resemble one another structurally and functionally. Though effective, these drugs are often promiscuous. With the realization that GPCRs signal via multiple pathways, and with the emergence of crystal structures for this family of proteins, there is an opportunity to target GPCRs with new chemotypes and confer new signaling modalities. We consider structure-based and physical screening methods that have led to the discovery of new reagents, focusing particularly on the former...

Tissue engineering, gene therapy, drug screening and emerging regenerative medicine therapies are fundamentally reliant on high-quality adherent cell culture, but current methods to cryopreserve cells in this format can give low cell yields and requires large volumes of solvent 'antifreezes'. Herein we report polyproline is a minimum (bio)synthetic mimic of antifreeze proteins, which is accessible by solution, solid phase and recombinant methods. We demonstrate that polyproline has ice recrystallization inhibition activity linked to its amphipathic helix and that it enhances the DMSO- cryopreservation of adherent cell lines...

Magnetic carbon nanotubes (MCNTs) have been widely studied for their potential applications in medicine, diagnosis, cell biology, analytical chemistry, and environmental technology. Introduction of MCNTs paved the way for the emergence of new approaches in nanobiotechnology and biomedicine as a result of their multifarious properties embedded within either the carbon nanotubes (CNTs) or magnetic parts. Numerous preparation techniques exists for functionalizing CNTs with magnetic nanoparticles, and these versatile strategies lay the ground for the generation of novel and versatile systems which are applicable to many industries and biological areas...

The technological advances in medicine, including prolongation of life, have constituted several dilemmas at the end of life. In the context of the Belgian debates on end-of-life care, the views of Muslim women remain understudied. The aim of this article is fourfold. First, we seek to describe the beliefs and attitudes of middle-aged and elderly Moroccan Muslim women toward withholding and withdrawing life-sustaining treatments. Second, we aim to identify whether differences are observable among middle-aged and elderly women's attitudes toward withholding and withdrawing life-sustaining treatments...

Developing strategies to detect single nucleotide DNA mutations associated with treatment decisions in cancer patients from liquid biopsies is a rapidly emerging area of personalized medicine that requires high specificity. Here we report how to design an easy enzyme-free approach that could create a platform for detection of L858R mutation of EGFR that is a predictive biomarker of tyrosine kinase treatment in many cancers. This approach includes the addition of blocking probes with the antisense ssDNA at different blocking positions and different concentrations such as to avoid re-annealing with the respective sense ssDNA...

Epilepsy may be the consequence of a wide range of disorders affecting the brain, including tumors and non-neoplastic lesions. A broad spectrum of structural brain lesions can be observed in epileptogenic brain tissue specimens surgically resected from patients with drug-resistant focal epilepsies. These include hippocampal sclerosis (HS), low-grade epilepsy-associated neuroepithelial tumors (LEAT), malformations of cortical development (MCD), vascular malformations, dual pathology, glial scar, and encephalitis, as well as no lesion...

PURPOSE OF REVIEW: To provide a fast overview about the introduction and development of anticholinergic drugs in Western medicine to their current indications particularly in asthma. RECENT FINDINGS: Although short-acting muscarinic antagonists have been positioned in the last 15 years for the treatment of adults and children with moderate-to-severe acute asthma in the emergency setting (reducing the risk of hospital admissions and improving lung function), a growing body of evidence has recently emerged that positions the long-acting muscarinic anticholinergic tiotropium bromide as add-on therapy to at least inhaled corticosteroids (ICS) maintenance therapy in adults, adolescents, and children with symptomatic asthma...
