A recent update of the Italian Road Traffic Law (RTL 41/2016), established severe penal sanctions when drivers, driving under the influence of alcohol (DUI) or drugs (DUID), are involved in road accident that results in death or injuries. A study was carried out to assess the trends of consumption of alcohol, illicit drugs or pharmaceutical among injured drivers suspected for DUI or DUID from 2009 to 2016 in the region of Campania (Italy). Confirmation toxicological analyses were performed on 780 blood samples and 1017 urine samples collected from 1797 injured drivers...

In Korea, an increasing number of people attempt to evade military conscription by posing as mental health patients. To verify the authenticity of mental illness, there is a need to detect wide range of psychoactive agents in biological specimens of conscription candidates. In this study, we developed and validated a liquid chromatography-tandem mass spectrometry (LC-MS/MS) method for simultaneous determination of 18 psychoactive agents and 6 metabolites in human plasma. The method was characterized by the use of a simple, fast and cheap protein precipitation as sample preparation, a rapid run time (11min) and a low volume of plasma sample (200μL)...

The Ginkgo biloba L. chichi is a unique organ. To explore the molecular mechanisms underlying the ontogenesis of G. biloba chichi, we used RNA-seq to analyse the transcriptome profile of rooted chichi at two developmental stages (ch1 and ch2) and nearby tissues (ck), and each sample had three biological replicates. A total of 57.74 Gb of clean bases were generated in nine cDNA libraries. These bases were de novo assembled into 68,277 unigenes with average length of 844 bp, and 51.47% of the unigenes had a match in at least one public database...

The gold standard methods for anaemia diagnosis are the complete blood count and the peripheral smear observation. However, they do not allow for a complete differential diagnosis, which requires biochemical assays, thus being label-dependent techniques. On the other hand, recent studies focus on label-free quantitative phase imaging (QPI) of blood samples to investigate blood diseases by using video-based morphological methods. However, when sick cells are very similar to healthy ones in terms of morphometric features identification of a blood disease becomes challenging even by morphometric as well as QPI...

Clinical mass spectrometry proteomics (cMSP) assays are being increasingly used in clinical laboratories for analyzing peptides and proteins. It has therefore become urgent to characterize and validate the methods available for liquid chromatography-tandem mass spectrometry (LC/MS-MS) targeted quantification of peptide and protein biomarkers in biological fluids in the context of in vitro diagnostics. LC-MS/MS for the detection of peptides and proteins is currently the main approach used in the field of cMSP...

How artificial environmental cues are biologically integrated and transgenerationally inherited is still poorly understood. Here, we investigate the mechanisms of inheritance of reproductive outcomes elicited by the model environmental chemical Bisphenol A in C. elegans. We show that Bisphenol A (BPA) exposure causes the derepression of an epigenomically silenced transgene in the germline for 5 generations, regardless of ancestral response. Chromatin immunoprecipitation sequencing (ChIP-seq), histone modification quantitation, and immunofluorescence assays revealed that this effect is associated with a reduction of the repressive marks H3K9me3 and H3K27me3 in whole worms and in germline nuclei in the F3, as well as with reproductive dysfunctions, including germline apoptosis and embryonic lethality...

N1-methyladenosine (m1 A) is an important post-transcriptional modification in RNA; however, the exact biological role of m1 A remains to be determined. By employing a quantitative proteomics method, we identified multiple putative protein readers of m1 A in RNA, including several YTH domain family proteins. We showed that YTHDF1-3 and YTHDC1, but not YTHDC2, could bind directly to m1 A in RNA. We also found that Trp432 in YTHDF2, a conserved residue in the hydrophobic pocket of the YTH domain that is necessary for its binding to N6 -methyladenosine (m6 A), is required for its recognition of m1 A...

Summary: Compared with the numerous software tools developed for identification and quantification of -omics data, there remains a lack of suitable tools for both downstream analysis and data visualization. To help researchers better understand the biological meanings in their -omics data, we present an easy-to-use tool, named PANDA-view, for both statistical analysis and visualization of quantitative proteomics data and other -omics data. PANDA-view contains various kinds of analysis methods such as normalization, missing value imputation, statistical tests, clustering and principal component analysis, as well as the most commonly-used data visualization methods including an interactive volcano plot...

α-Diimines are among the most robust and versatile ligands available in synthetic coordination chemistry, possessing finely tunable steric and electronic properties. A series of novel cationic ruthenium(II) p-cymene complexes bearing simple α-diimine ligands, [(η6 - p-cymene)RuCl{κ2 N-(HCNR)2 }]NO3 (R = Cy, [1]NO3 ; R = 4-C6 H10 OH, [2]NO3 ; R = 4-C6 H4 OH, [3]NO3 ), were prepared in near-quantitative yields as their nitrate salts. [2]NO3 displays high water solubility. The potential of the α-diimine ligand in [3]NO3 as a carrier of bioactive molecules was investigated via esterification reactions with the hydroxyl groups...

Smart toilets could be used to monitor different components of urine in daily life for early detection of lifestyle-related diseases and prompt provision of treatment. For analysis of biological samples such as urine by midinfrared spectroscopy, thin-film samples like liquid cells are needed because of the strong absorption of midinfrared light by water. Conventional liquid cells or fixed cells are prepared based on the liquid membrane method and solution technique, but these are not quantitative and are difficult to set up and clean...

Long non-coding RNAs (lncRNAs) are a new class of regulators of various human diseases. This study was designed to explore the potential role of lncRNAs in experimental hepatic damage. In vivo hepatic damage in mice and in vitro hepatocyte damage in AML12 and NCTC1469 cells were induced by carbon tetrachloride (CCl4 ) treatments. Expression profiles of lncRNAs and mRNAs were analyzed by microarray. Bioinformatics analyses were conducted to predict the potential functions of differentially expressed lncRNAs with respect to hepatic damage...

The Universal Gene Set of Life (UGSL) is common to genomes of all extant organisms. The UGSL is small, consisting of less than 100 genes, and is dominated by genes encoding the translation system. Here we extend the search for biological universality to three dimensions. We characterize and quantitate the universality of structure of macromolecules that are common to all of life. We determine that around 90% of prokaryotic rRNA forms a common core, which are the structural and functional foundation of rRNAs of all cytoplasmic ribosomes...

Angelman syndrome is a complex neurodevelopmental disorder caused by the lack of function in the brain of a single gene, UBE3A. The E3 ligase coded by this gene is known to build K48-linked ubiquitin chains, a modification historically considered to target substrates for degradation by the proteasome. However, a change in protein abundance is not proof that a candidate UBE3A substrate is indeed ubiquitinated by UBE3A. We have here used an unbiased ubiquitin proteomics approach, the bioUb strategy, to identify 79 proteins that appear more ubiquitinated in the Drosophila photoreceptor cells when Ube3a is over-expressed...

Biofilm formation influences the most energy-demanding process in the waste water treatment cycle. Biofilm growth on the surface of wastewater aeration diffusers in water resource recovery facilities (WRRFs) can increase the energy requirements up to 50% in less than 2 years. The impact of biofilms in aeration diffusers was quantified and assessed for first time using molecular tools (i.e., Energy-dispersive X-ray, Ra and RMS and Pyrosequencing) and state-of-the-art techniques (i.e., EPS quantification, Hydrophobicity and DNA quantification)...

Limitations in obtaining surgically resected or biopsy samples of small cell lung cancer (SCLC) tumors make comprehensive biological analyses difficult. The loss of thyroid transcription factor 1 (TTF-1) has been associated with the aggressive behavior of non-small cell lung cancer (NSCLC); however, clinicopathological features of TTF-1-negative SCLC remain unclear. This study aimed to elucidate the characteristics of TTF-1-negative SCLC. We studied the associations between the expression of TTF-1 and the clinicopathological factors associated with SCLC, including survival and expression of neuroendocrine markers (synaptophysin, chromogranin A, and CD56), neuroendocrine cell-specific transcription factors (achaete-scute homolog like 1 (ASCL1), BRN2), a proliferation marker (Ki-67 labeling index), and an oncogene (Nuclear Factor 1B (NF1B))...

Transposable elements (TEs), segments of DNA capable of self-replication, are abundant in the genomes of most organisms and thus serve as a record of past mutational events. While some work suggests TEs may serve a regulatory function for the host, most empirical and theoretical studies have shown that TEs often have deleterious effects on a host. Because they are not essential, the host genome consists of both full-length (actively replicating) and partial length (inactive remnant) copies of TEs. We developed a novel mathematical formulation of TE dynamics by modeling the density of full and partial length copies resulting from mutations (insertions and deletions) and TE replication within the host genome...

Stereospecific recognition of chiral molecules is ubiquitous in chemical and biological systems, thus leading to a strong de-mand for the development of enantiomeric drugs, enantioselective sensors, and asymmetric catalysts. In this study, we demonstrate the ratio of D-Cys and L-Cys playing an important role in determining the optical properties and the structures of self-assembled Cys-Au(I) supramolecules prepared through a simple reaction of tetrachloroaurate(III) with chiral cyste-ine (Cys). The irregularly shaped -[D-Cys-Au(I)] n - or -[L-Cys-Au(I)] n - supramolecules with a size larger than 500 nm pos-sessing strong absorption in the near-UV region and chiroptical characteristics were only obtained from the reaction of Au(III) with D-Cys or L-Cys...
