BACKGROUND: Several studies have demonstrated that approximately one-half of patients with chronic myeloid leukemia (CML) who receive treatment with tyrosine kinase inhibitors (TKIs) and achieve and maintain a deep molecular response (DMR) are able to successfully discontinue therapy. In patients who have a molecular relapse, a DMR is rapidly regained upon treatment re-initiation. METHODS: The authors report the results from RE-STIM, a French observational, multicenter study that evaluated treatment-free remission (TFR) in 70 patients who re-attempted TKI discontinuation after a first unsuccessful attempt...

Akbar Esmaeili, Sahar Behzadi
In this study, the performance of two kinds of industrial and herbal drugs encapsulated in nanoparticles with a shell of starch and cellulose and an alginate core were examined as a new technique for nanoparticle drug delivery. The test method involved creating a suspension of starch and alginate, which was then dried, mixed with cellulose, and heated to form core-shell nanoparticles. The industrial drug calcitonin and an extract of the herb Amaranthus retroflexcus L. were added separately and in combination to the nanoparticles, and the performance of each configuration was evaluated...

Kai Chun Nien, Feng Tang Chang, Moo Been Chang
Mesitylene (or 1,3,5-trimethylbenzene) is a volatile organic compound emitted from various industrial processes, e.g., spray coating. Its emissions have become a critical issue because mesitylene is toxic and cannot be removed using traditional adsorbents, e.g., zeolite (H-ZSM-5; the diameter of mesitylene molecules is greater than the pore size of H-ZSM-5). Hence, an adsorbent with a large pore size, MCM-41, is used in this study to investigate its adsorption capacity for mesitylene and is compared with that of H-ZSM-5...

BACKGROUND: Evidence suggests that for young adults, intimate partners influence each other's drinking patterns. Therefore, exploration of variables related to intimate partner relationships (such as attachment style) could broaden the current understanding of risk factors for alcohol problems in this demographic. OBJECTIVES: The current study examined the role of drinking context in the relationships among insecure attachment, alcohol problems, and relationship satisfaction...

Sung Bae Kim, Ryo Nishihara, Daniel Citterio, Koji Suzuki
The fabrication of artificial luciferases (ALucs) with unique optical properties can have a fundamental impact on bioassays and molecular imaging. In this study, we developed a new lineage of ALucs with unique substrate preferences by extracting consensus amino acids from the alignment of 25 copepod luciferase sequences available in published databases. The primary sequence was first created with a sequence logo generator resulting in a total of 11 sibling sequences. Phylogenetic analysis shows that the newly fabricated ALucs form an independent branch, genetically isolated from the natural luciferases and from a prior series of ALucs produced by our laboratory using a smaller basis set...

PURPOSE: The lamina cribrosa (LC) is known to play a critical role in the pathogenesis of glaucoma. Although it has been reported that striae-shaped or slit-shaped lamina pores are more frequent in eyes with primary open angle glaucoma (POAG), this observation is based only on fundus photography. The primary object of this study is to perform layer-by-layer comparisons of the shape of lamina pores within the LC in vivo. DESIGN: Cross-sectional study. METHODS: Optic nerve head B-scans were obtained using custom-made broad-wavelength optical coherence tomography with a mode-locked laser...

BACKGROUND: Survival rates remain low after hemorrhage-induced traumatic cardiac arrest (TCA). Noncompressible torso hemorrhage (NCTH) is a major cause of potentially survivable trauma death. Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) at the thoracic aorta (Zone 1) can limit subdiaphragmatic blood loss and allow for IV fluid resuscitation when intrinsic cardiac activity is still present. Selective Aortic Arch Perfusion (SAAP) combines thoracic aortic balloon hemorrhage control with intra-aortic oxygenated perfusion to achieve return of spontaneous circulation (ROSC) when cardiac arrest has occurred...

BACKGROUND: Leukocyte telomere length (LTL) is a potential biomarker of cancer prognosis; however, evidence for renal cell carcinoma (RCC) is inconsistent. METHODS: We investigated LTL and RCC-specific survival among 684 cases from the US kidney cancer study (USKC) and 241 cases from the prostate, lung, colorectal, and ovarian cancer screening trial (PLCO). Leukocyte telomere length was measured by quantitative polymerase chain reaction, and hazard ratios (HRs) and 95% confidence intervals (CIs) computed using multivariable Cox models...

BACKGROUND: The molecular mechanisms involved in the invasion of bone by oral squamous cell carcinomas (OSCC) are poorly understood, and little is known about the role of cancer-associated fibroblasts (CAF), the presence of which confers a poor prognosis. METHODS: Clinicopathological data from 277 OSCC cases involving bone resections were reviewed, and 32 cases thoroughly analysed histologically. Immunohistochemistry was used to examine αSMA, RANKL and OPG. Western blotting and qPCR were used to assess myofibroblast (CAF-like) differentiation, RANKL and OPG expression in vitro, and RANKL secretion was analysed by ELISA...

BACKGROUND: Vascular endothelial growth factor (VEGF) and its receptors (VEGFRs) are key regulators of angiogenesis, affecting endothelial cell survival and function. However, the effect of VEGF-VEGFR signalling on tumour cell function is not well understood. Our previous studies in colorectal cancer (CRC) cells have demonstrated an intracrine VEGF/VEGFR1 signalling mechanism that mediates CRC cell survival and chemo-sensitivity. Since extracellular VEGF signalling regulates migration of endothelial cells and various tumour cells, we attempted to determine whether intracrine VEGF signalling affects CRC cell motility...
