The present study predicts a spatial distribution of lung cancer morbidity in Chinese males due to exposure to PM2.5 concentration from 2010 to 2015. A spatial autocorrelation method was used to evaluate the spatial relationship between the lung cancer morbidities from 2006 to 2009 and satellite-derived PM2.5 atmospheric levels. A comprehensive grey correlation degree analysis was carried out to assess the simultaneous and lag associations between the lung cancer morbidity and PM2.5 concentration. These relationships were subsequently applied to predict male lung cancer morbidity in a specific year...

A facile and scalable method has been realized for the in-situ synthesis of N/S co-doping 3D porous carbon nanosheet networks (NSPCNN) as sodium-ion battery anode material. During the synthesis, NaCl is used for a template to prepare porous carbon nanosheet networks. In the resultant architecture, the unique 3D porous architecture ensures large specific surface area and fast diffusion path of both electrons and ions. Meanwhile, the import of N/S produces abundant defects, increased interlayer space, more active sites and high electronic conductivity...

Computational modeling has been applied to simulate the heterogeneity of cancer behavior. The development of Cervical Cancer (CC) is a process in which the cell acquires dynamic behavior from non-deleterious and deleterious mutations, exhibiting chromosomal alterations as a manifestation of this dynamic. To further determine the progression of chromosomal alterations in precursor lesions and CC, we introduce a computational model to study the dynamics of deleterious and non-deleterious mutations as an outcome of tumor progression...

INTRODUCTION: High-tension electricity can cause devastating injuries that may result in abdominal wall loss, visceral damage, and sometimes major threat to life. The visceral organ may be exposed after debridement and require flap cover, but the tensile strength of abdominal wall may be lack even if flap transplanted. METHODS: From April 2007 through May 2015, 5 patients with severe abdominal electrical injury were treated at our hospital. Exploratory laparotomy was performed based on their clinical manifestations and debridement findings of abdominal wall at early stage, and decision regarding technique for reconstruction of abdominal wall was based on an assessment of the location and extent of the defect...

Franz Gunter Frosch
INTRODUCTION: "The hum" or "Taos hum" are common terms of a tinnitus with three remarkable features. OBJECTIVE: A possible common background is reevaluated for the three features of the hum: being sensitive on sound, head rotation, and long-distance air travel. MATERIALS AND METHODS: Questionnaires that were originally developed by Frosch were recalculated concerning the question of hum interactions with sounds. The question was split into the two affirmative answers a) "masking", which corresponds to the overrule of the hum by a sound, and b) "beats", which correspond to a nonlinear interaction with the hum as a Van der Pol-like oscillator...

Myelodysplastic syndromes and chronic myelomonocytic leukemia are blood disorders characterized by ineffective hematopoiesis and progressive marrow failure that can transform into acute leukemia. The DNA methyltransferase inhibitor 5-azacytidine (AZA) is the most effective pharmacological option, but only ∼50% of patients respond. A response only manifests after many months of treatment and is transient. The reasons underlying AZA resistance are unknown, and few alternatives exist for non-responders. Here, we show that AZA responders have more hematopoietic progenitor cells (HPCs) in the cell cycle...

Visual perceptual learning through practice or training can significantly improve performance on visual tasks. Originally seen as a manifestation of plasticity in the primary visual cortex, perceptual learning is more readily understood as improvements in the function of brain networks that integrate processes, including sensory representations, decision, attention, and reward, and balance plasticity with system stability. This review considers the primary phenomena of perceptual learning, theories of perceptual learning, and perceptual learning's effect on signal and noise in visual processing and decision...

The organelle-specific pH is crucial for cell homeostasis. Aberrant pH of lysosomes has been manifested in myriad diseases. To probe lysosome responses to cell stress, we herein report the detection of lysosomal pH changes with a dual colored probe (CM-ROX), featuring a coumarin domain with "always-on" blue fluorescence and a rhodamine-lactam domain activatable to lysosomal acidity to give red fluorescence. With sensitive ratiometric signals upon subtle pH changes, CM-ROX enables discernment of lysosomal pH changes in cells undergoing autophagy, cell death, and viral infection...

Protein phosphorylation is by far the most abundant and most studied post-translational modification (PTM). For a long time, phosphate monoesters of serine (pSer), threonine (pThr), and tyrosine (pTyr) have been considered as the only relevant forms of phosphorylation in organisms. Recently, several research groups have dedicated their efforts to the investigation of other, less characterized phosphoamino acids as naturally occurring PTMs. Such apparent peculiar phosphorylations include the phosphoramidates of histidine (pHis), arginine (pArg), and lysine (pLys), the phosphorothioate of cysteine (pCys), and the anhydrides of pyrophosphorylated serine (ppSer) and threonine (ppThr)...

Protein ageing may manifest as a mechanical disease that compromises tissue elasticity. As proved recently, while proteins respond to changes in force with an instantaneous elastic recoil followed by a folding contraction, aged proteins break bad, becoming unstructured polymers. Here, we explain this phenomenon in the context of a free energy model, predicting the changes in the folding landscape of proteins upon oxidative ageing. Our findings validate that protein folding under force is constituted by two separable components, polymer properties and hydrophobic collapse, and demonstrate that the latter becomes irreversibly blocked by oxidative damage...

Application of colloidal semiconductor quantum dots (QDs) in optical and optoelectronic devices is often complicated by unintentional generation of extra charges, which opens fast nonradiative Auger recombination pathways whereby the recombination energy of an exciton is quickly transferred to the extra-carrier(s) and ultimately dissipated as heat. Previous studies of Auger recombination have primarily focused on neutral, and more recently, negatively charged multi-carrier states. Auger dynamics of positively charged species remains more poorly explored due to difficulties in creating, stabilizing, and detecting excess holes in the QDs...

Primary Familial Brain Calcification (PFBC) is an autosomal dominant rare disorder characterized by bilateral and symmetric brain calcifications and neuropsychiatric manifestations. Four genes have been linked to PFBC: SLC20A2, PDGFRB, PDGFB and XPR1. In this study, we report molecular and clinical data of a PFBC patient carrying a novel SLC20A2 mutation and we investigate the impact of the mutation on PiT-2 expression and function. Sanger sequencing of SLC20A2, PDGFRB, PDGFB, XPR1 led to the identification of a novel duplication of twelve nucleotides (c...
