BACKGROUND: Thyroid dysfunction (TD) was usually described in hematopoietic stem cell transplantation (HSCT) recipients who were given total body irradiation (TBI) in the conditioning regimen. Because previous studies have reported discrepant results regarding the presence of long-term thyroid complications in HSCT survivors following chemotherapy-only conditioning, we investigated the frequency of thyroid abnormalities in a series of children treated with HSCT for different disorders without TBI as part of the conditioning protocol...

High-level ab initio calculations on the complexes between noble gas atoms (He, Ne, Ar, Kr, and Xe) and dihalogen molecules (F2 , Cl2 , Br2 , and I2 ) reveal trends, both in interaction energies and the energy difference between the linear and T-shaped structures, that can be explained well in terms of dispersion interactions enhanced by polar flattening of the halogens. The partial discrepancies with experimental findings are discussed. Graphical abstract The molecular electrostatic potential (red positive, blue negative) of Cl2 ...

Cesare Granata, Nicholas A Jamnick, David J Bishop
A sedentary lifestyle has been linked to a number of metabolic disorders that have been associated with sub-optimal mitochondrial characteristics and an increased risk of premature death. Endurance training can induce an increase in mitochondrial content and/or mitochondrial functional qualities, which are associated with improved health and well-being and longer life expectancy. It is therefore important to better define how manipulating key parameters of an endurance training intervention can influence the content and functionality of the mitochondrial pool...

Relative electron densities of body tissues (ρe ) for radiotherapy treatment planning are normally obtained by CT scanning of tissue substitute materials (TSMs) and producing a Hounsfield Unit-ρe calibration curve. Aiming for more accurate, simultaneous characterization of ρe and effective atomic number (Zeff ) of real tissues, an in-house phantom (including 10 water solutions plus composite cork as TSMs) was constructed and scanned at 4 kVps. Dual-energy algorithms were applied to 80-140 and 100-140 kVp combination scans, for better differentiation of tissues with same attenuation coefficient at 120 kVp but different ρe and Zeff ...

Selecting appropriate tools providing reliable quantitative measures of individual populations in biofilms is critical as we now recognize their true polymicrobial and heterogeneous nature. Here, plate count, quantitative real-time polymerase chain reaction (q-PCR) and peptide nucleic acid probe-fluorescence in situ hybridization (PNA-FISH) were employed to quantitate cystic fibrosis multispecies biofilms. Growth of Pseudomonas aeruginosa, Inquilinus limosus and Dolosigranulum pigrum was assessed in dual- and triple-species consortia under oxygen and antibiotic stress...

Ferroptosis is an iron-dependent form of programmed cell death characterized by the accumulation of lipid-targeting reactive oxygen species that kill cells by damaging their plasma membrane. The lipid-repair enzyme glutathione peroxidase 4 (GPX4) protects against this oxidative damage and enables cells to resist ferroptosis. Recent work has revealed that matrix-detached carcinoma cells can be susceptible to ferroptosis and that they can evade this fate through the signaling properties of the α6β4 integrin, which sustains GPX4 expression...

PURPOSE: Stereotactic body radiation therapy (SBRT) for hepatocellular carcinoma (HCC) has emerged as an alternative treatment option when curative treatment modalities cannot be applied. Although excellent local tumor control has been achieved with SBRT, the targeting accuracy in real-life practice remains poorly understood. We proposed an in vivo assessment of targeting accuracy using hepatic parenchymal changes observed on gadolinium ethoxybenzyl diethylenetriaminepentaacetic acid (Gd-EOB-DTPA)-enhanced magnetic resonance (MR) images and applied this method to investigate the "real-life" targeting accuracy of image-guided SBRT...

Tang-Huang Lin, Min-Chung Hsiao, Hai-Po Chan, Fuan Tsai
Radiometric calibration for imaging sensors is a crucial procedure to ensure imagery quality. One of the challenges in relative radiometric calibration is to correct detector-level artifacts due to the fluctuation in discrepant responses (spatial) and electronic instability (temporal). In this paper, the integration of the empirical mode decomposition (EMD) with Hilbert⁻Huang transform (HHT) in relative radiometric calibration was explored for a new sensor, FS-5 RSI (remote sensing instrument onboard the FORMOSAT-5 satellite)...

Complete talar extrusion is rare and usually associated with a high-energy mechanism of injury causing complete dissociation of the talus from the surrounding bony and soft-tissue structures with enough force to expel the talus out of the body. Treatment can be complicated by infection, osteonecrosis, posttraumatic osteoarthritis, and leg length discrepancy, which may require multiple subsequent surgeries for improved outcome and quality of life. Reimplantation of the native talus affords maintenance of joint height and favorable outcomes have been reported...

The repressive activity of ancestral histone-like proteins helps integrate transcription of foreign genes with discrepant AT content into existing regulatory networks. Our investigations indicate that the AT-rich discriminator region located between the -10 promoter element and the transcription start site of the regulatory gene ssrA plays a distinct role in the balanced expression of the Salmonella pathogenicity island-2 (SPI2) type III secretion system. The RNA polymerase-binding protein DksA activates the ssrAB regulon post-transcriptionally, whereas the alarmone guanosine tetraphosphate (ppGpp) relieves the negative regulation imposed by the AT-rich ssrA discriminator region...

Viticis Fructus is a traditional Chinese herbal drug processed by various methods to achieve different clinical purposes. Thermal treatment potentially alters chemical composition, which may impact on effectiveness and toxicity. In order to interpret the constituent discrepancies of raw versus processed (stir-fried) Viticis Fructus, a multivariate detection method (NIR, HPLC, and UPLC-MS) based on metabonomics and chemometrics was developed. Firstly, synergy interval partial least squares and partial least squares-discriminant analysis were employed to screen the distinctive wavebands (4319 - 5459 cm-1 ) based on preprocessed near-infrared spectra...
