Methods are evaluated in solution of the inverse problem associated with determination of elastic moduli for crystals of arbitrary symmetry from elastic wave velocities measured in many crystallographic directions. A package of MATLAB functions provides a robust and flexible environment for analysis of ultrasonic, Brillouin, or Impulsive Stimulated Light Scattering datasets. Three inverse algorithms are considered: the gradient-based methods of Levenberg-Marquardt and Backus-Gilbert, and a non-gradient-based (Nelder-Mead) simplex approach...

Previous work has shown that exposure to images of nature results in elevated state body appreciation, but static images may lack ecological validity. Here, we examined the impact of exposure to short films of simulated, first-person walks in natural or built environments. Thirty-six university students completed a measure of state body appreciation before and after watching films of either a walk in a natural or a built environment created specifically for the present study. Two weeks later, they completed the same task but watched the other film type...

Unfavorable environmental conditions and inappropriate culture practices have increased the vulnerability of cultured fish to disease infection. Up to date many studies have aimed to determine a feeding regimen to maximize productivity; however, very little information on immune responses of cultured fish in response to underfeeding or overfeeding is available. Therefore, a preliminary study was conducted to evaluate effects of graded feeding levels (i.e., food availability) on growth performance and immune-related gene expression of juvenile olive flounder (Paralichthys olivaceus)...

Despite the well-known role of satellite cells in skeletal muscle plasticity, the effect of spinal cord injury on their function in humans remains unknown. We determined whether spinal cord injury affects the intrinsic ability of satellite cells to differentiate and produce metabolically healthy myotubes. We obtained vastus lateralis biopsies from eight spinal cord-injured and six able-bodied individuals. Satellite cells were isolated, grown and differentiated in vitro. Gene expression was measured by quantitative PCR...

Oxicams (e.g. piroxicam, meloxicam) are widely used nonsteroidal anti-inflammatory drugs (NSAIDs). A large body of evidence from epidemiological and preclinical studies has shown that NSAIDs have a chemopreventive effect on different types of cancer, especially in colorectal cancer. Moreover, mounting evidence from preclinical and clinical studies suggests that persistent inflammation functions as a driving force in the journey to cancer. What is more, inflammation induces reactive oxygen and nitrogen species, which cause damage to important cellular components (e...

The ribosome is a major antibiotic target. Many types of inhibitors can stop cells from growing by binding at functional centers of the ribosome and interfering with its ability to synthesize proteins. These antibiotics were usually viewed as general protein synthesis inhibitors, which indiscriminately stop translation at every codon of every mRNA, preventing the ribosome from making any protein. However, at each step of the translation cycle, the ribosome interacts with multiple ligands (mRNAs, tRNA substrates, translation factors, etc...

Zic family genes encode C2H2-type zinc finger proteins that act as critical toolkit proteins in the metazoan body plan establishment. In this study, we searched evolutionarily conserved domains among 121 Zic protein sequences from 22 animal phyla and 40 classes, and addressed their evolutionary significance. The collected sequences included those from poriferans and orthonectids. We discovered seven new conserved domains (CDs), CD0-CD6, (in order from the N- to C-terminus) using the most conserved Zic protein sequences from Deuterostomia (Hemichordata, Cephalochordata), Lophotrochozoa (Cephalopoda and Brachiopoda), and Ecdysozoa (Chelicerata, Priapulida)...

Common postictal MRI findings include transient cortical T2 hyperintensity, restricted diffusion, and gyral and/or adjacent leptomeningeal contrast enhancement. In certain uncommon pathological conditions, other signal abnormalities can be present, suggesting a different underlying pathogenic mechanism. We report the case of a 66-year-old man, recently diagnosed with diabetes mellitus type 2, presenting with new-onset visual and auditory hallucinations, "absence" seizures, and repeated peaks of hyperglycaemia without hyperketonaemia or increased serum osmolarity...

This study compared three-dimensional (3D) and two-dimensional (2D) percentage gamma passing rates (%GPs) for detection sensitivity to IMRT delivery errors and investigated the correlation between two kinds of %GP. Eleven prostate IMRT cases were selected, and errors in multileaf collimator (MLC) bank sag, MLC leaf traveling, and machine output were simulated by recalculating the dose distributions in patients. 2D doses were extracted from the 3D doses at the isocenter position. The 3D and 2D %GPs with different gamma criteria were then obtained by comparing the recalculated and original doses in specific regions of interest (ROI), such as the whole body, the planning target volume (PTV), the bladder, and the rectum...

The greatest challenge facing medicine today involves the so-called non-communicable diseases (NCDs). This is true regardless of whether one's location is considered high-income, middle-income, or low-income. Basic research at all "OMICs" system levels will be significant in uncovering causal links that create NCD vulnerabilities in mind, brain, body, and society. Therefore, meeting this 21st century challenge by improving NCD management and prevention around the world will rely on advancement in this type of basic research...

OBJECTIVE: The E3 ubiquitin ligase IDOL (inducible degrader of the LDLR [LDL (low-density lipoprotein) receptor]) is a post-transcriptional regulator of LDLR abundance. Model systems and human genetics support a role for IDOL in regulating circulating LDL levels. Whether IDOL plays a broader metabolic role and affects development of metabolic syndrome-associated comorbidities is unknown. APPROACH AND RESULTS: We studied WT (wild type) and Idol ( -/ - ) (Idol-KO) mice in 2 models: physiological aging and diet-induced obesity...

Oxidative phosphorylation (OXPHOS), a fundamental energy source in all human tissues, requires interactions between mitochondrial (mtDNA) and nuclear (nDNA)-encoded protein subunits. Although such interactions are fundamental to OXPHOS, bi-genomic co-regulation is poorly understood. To address this question, we analyzed ~8,500 RNA-seq experiments from 48 human body sites. Despite well-known variation in mitochondrial activity, quantity and morphology, we found overall positive mtDNA-nDNA OXPHOS genes' co-expression across human tissues...

Human lymphoblast cells from a male diagnosed with Alzheimer's disease (AD) expressing the TREM2 p.R47H variant were used to generate integration-free induced pluripotent stem cells (iPSCs) by over-expressing episomal-based plasmids harbouring OCT4, SOX2, KLF4, LIN28, L-MYC and p53 shRNA. The derived iPSC line - AD-TREM2-3 was defined as pluripotent based on (i) expression of pluripotency-associated markers (ii) embryoid body-based differentiation into cell types representative of the three germ layers and (iii) the similarity between the transcriptome of the iPSC line and the human embryonic stem cell line H1 with a Pearson correlation of 0...
