The results show that serious spectral drifts and intensity variation in NaI (Tl) gamma spectra were effectively eliminated. The maximum relative drift of peak position, the maximum relative variation of peak height and that of FWHM before correction were 65.03%, 40.37% and 61.65%, respectively, and after correction, they became 0.19%, 2.81% and 0.85%, respectively, indicating that the method has strong ability to correct gamma spectra. HPGe gamma spectra were also well corrected using the presented method, and were identified as gamma radiation fingerprints of nuclear materials. The results show that the method can also improve the confidence degree of identifying nuclear materials significantly.Alzheimer's is a fatal neurodegenerative disease for which there is no cure at present. The disease is characterized by the presence of plaques in the brains of a patient, which are composed mainly of aggregates of the amyloid-β peptide in the form of β-sheet fibrils. Here, we investigated the possibility of exploiting the superior binding ability of aromatic amino acids to a particular model of the amyloid-β fibrils. which is a difficult target for drug design. The β-sheet breaker peptide LPFFD was modified with aromatic amino acids and its binding to these fibrils was studied. We found that the orientation and the electrostatic complementarity of the modified peptide with respect to the fibrils played a crucial role in determining whether its binding was improved by the aromatic amino acids. The modified LPFFD peptides were able to bind to those fibril residues. which are important in the aggregation of amyloid-β peptides and thus can potentially inhibit the further aggregation of the amyloid-beta peptides by blocking their interactions. We found that the tryptophan modified LPFFD peptides had the best binding affinities. In most cases, the aromatic amino acids in the N-terminus of the modified peptides made more contacts with the fibrils than those in the C-terminus. We also found that increasing the aromatic content did not significantly improve the binding of the LPFFD peptide to the fibrils. Our study can serve as a basis for the design of novel peptide-based drugs for Alzheimer's disease in which aromatic interactions play an important role.Flexible resource models suggest that attentional deployment in Multiple Object Tracking either shows in target enhancement or distractor inhibition or both. In order to gauge the influence of these processes we manipulated distinctiveness of targets and distractors along a single dimension by finely grading gray values of objects. We established that a quantitative increase in distinctiveness results in a quantitative increase in tracking performance thus demonstrating a new finding. Further increases of distinctiveness beyond a certain degree produced no further improvements in tracking. This effect, however, was moderated by levels of task difficulty thus providing evidence for the relativity of this effect. With higher task difficulty higher degrees of distinctiveness still resulted in a significant performance gain (Experiment 1). A follow up experiment generalized this finding. By manipulating speed of objects, a situation with a yet higher task difficulty could be established showing that an increase of an already striking distinctiveness can produce an even further performance gain - provided higher task difficulty (Experiment 2). Finally we tested the hypothesis that target enhancement and distractor inhibition are influenced by feature distinctiveness. Although we found possible indications for distractor inhibition, we could not demonstrate an effect of feature distinctiveness on distractor inhibition. Target enhancement, however, was substantially influenced by variation of feature distinctiveness (Experiment 3).Being independent contributors to bone mechanical resistance at the apparent level, quality and quantity of bone primary constituents are essential factors in better fracture risk assessment. Raman spectroscopy (RS) holds great potential for being a clinical tool with providing quality and quantity measurements of the bone mineralized matrix. Beyond mineral quality and quantity, recent years have revealed newly developed RS-derived bone compositional measurements focusing on organic matrix and water though their associations with bone mechanics have not been fully established yet. Herein, the author reported first thorough characterization study investigating associations between twenty different RS-derived measurements and mechanical properties of human cortical bone (i.e., yield and ultimate strength, elastic modulus, toughness, post-yield toughness, and post-yield strain). Forty-five rectangular human cortical beams harvested from all four anatomical quadrants of two male donors were tested under three-point bending. Raman spectra of each specimen were collected at the spectral range of 800 to 4000 cm-1. While correlations were tested among RS-derived measurements via Spearman's rank correlations, multivariate linear regression using mixed effects were used to determine the best RS-derived measurement or the combination of RS-derived measurements in predicting various mechanical properties of human cortical bone. Most of the RS-derived measurements were associated with the mechanical properties (Rm2 ranges from 8.9 to 68.3%, p less then 0.05). The various linear combinations of six RS-derived measurements focusing on different aspects of bone matrix (i.e., ν1PO4/Amide I, ν1PO4/Amide III, Carbonate/ν1PO4, ~I1670/I1640, ~I3453/I2949, ~I3584/I2949) improved the prediction (Rm2 = 43.5 to 70.2%, p less then 0.05). While a causal relationship still needs to be investigated, RS has a great potential to establish a robust patient-specific fracture risk prediction with the latest advances in technologies.
A vast majority of patients with NSCLC (non-small cell lung cancer) have lung adenocarcinoma (LA), and the survival rate of LA varies from 5% to 75% depending on the severity of this adenocarcinoma. PYCR1 (abnormal pyrroline-5-carboxylate reductase 1) gene and miR-328-3p have been found to be associated with cancer development. However, the underlying mechanism of interaction between miR-328-3p and PYCR1 in LA needs further investigation.

The expressions of miR-328-3p and PYCR1 in samples with LA were identified by RT-qPCR. AZD7545 Next, we investigated the targeting relationship between these two biological factors using luciferase assay. CCK-8, BrdU, transwell-migration, and flow cytometry assays were performed to detect cell viability, cell proliferation, cell migration and cell apoptosis in LA cells.

We noticed that miR-328-3p expression was downregulated in LA samples. MiR-328-3p mimic restricted cell proliferation and cell migration, while it enhanced cell apoptosis. Furthermore, the overexpression of PYCR1 promoted the proliferation and migration of LA cells, but it repressed cell apoptosis. link2 Moreover, PYCR1 directly interacted with miR-328-3p in the LA cells, and miR-328-3p restrained the expression of PYCR1, thus suppressing LA tumorigenesis.

In summary, our study revealed that miR-328-3p targeting to PYCR1 suppressed the malignancy of LA cells by impeding cell proliferation and migration, while effectively promoting cell apoptosis.

Lamins consist of the N-terminal unstructured head, the coiled-coil rod domain, and the C-terminal tail, which is mostly unstructured except for the Ig-like domain. To date, the Ig-like domain has been characterized as a monomeric structure. Here, we determined the crystal structures of human lamin A/C, including the Ig-like domain and its N- and C-terminal flanking sequences. Interestingly, the structures showed a homodimer formed by beta-strand interactions between the N- and C-terminal flanking sequences. This interaction also provides a molecular implication for the creation of a 3-D meshwork between the 3.5-nm-thick filaments. Furthermore, we determined the crystal structure of the corresponding region of lamin B1. The structure showed a similar dimeric assembly, also formed by beta-strand interactions, albeit the intersubunit distance was much shorter. Since the Ig-like domain contains many genetic hotspots causing lamin-related diseases in lamin A/C, our findings will help understand the detailed assembly of lamins in a 3-D meshwork structure and lamin-related diseases at the molecular level.Linear ubiquitination is an atypic ubiquitination process that directly connects the N- and C-termini of ubiquitin and is catalyzed by HOIL-1-interacting protein (HOIP). It is involved in the immune response or apoptosis by activating the nuclear factor-κB pathway and is associated with polyglucosan body myopathy 1, an autosomal recessive disorder with progressive muscle weakness and cardiomyopathy. However, little is currently known regarding the function of linear ubiquitination in muscles. Here, we investigated the role of linear ubiquitin E3 ligase (LUBEL), a DrosophilaHOIP ortholog, in the development and aging of muscles. The muscles of the flies with down-regulation of LUBEL or its downstream factors, kenny and Relish, developed normally, and there were no obvious abnormalities in function in young flies. However, the locomotor activity of the LUBEL RNAi flies was reduced compared to age-matched control, while LUBEL RNAi did not affect the increased mitochondrial fusion or myofiber disorganization during aging. Interestingly, the accumulation of polyubiquitinated protein aggregation during aging decreased in muscles by silencing LUBEL, kenny, or Relish. Meanwhile, the levels of autophagy and global translation, which are implicated in the maintenance of proteostasis, did not change due to LUBEL down-regulation. In conclusion, we propose a new role of linear ubiquitination in proteostasis in the muscle aging.Free fatty acid receptor 1 (FFAR1 or GPR40) has attracted attention for the treatment of type 2 diabetes mellitus, and various small-molecule agonists have been developed. However, most FFAR1 agonists as well as endogenous ligands, such as linoleic acids, have high lipophilicity, and their high lipophilicity is related to off-target toxicity. Therefore, we need to focus on new ligand candidates with less toxicity. In this study, we screened peptides with FFAR1 agonist activity as new ligand candidates. First, we used phage display to identify peptides with high affinity to FFAR1. Next, the agonist activities of peptides determined by the phage display were evaluated by the TGF-α shedding assay. link3 Finally, to improve the FFAR1 agonist activity of the peptide, we performed an inclusive single amino acid substitution and sequence analysis. Logistic regression (LR) analysis using 120 physiochemical properties was performed to predict peptides with high FFAR1 agonist activity. STTGTQY determined by phage display promoted glucose-stimulated insulin secretion in pancreatic MIN6 cells. Furthermore, STKGTF predicted by the LR analysis showed high insulin secretion at low concentrations compared to STTGTQY. The results of this study suggest that peptides could be new candidates as FFAR1 agonists.
