Involvement of nuclear atrophy of binucleated hepatocytes in the large micronucleus formation induced by rat hepatocarcinogen acetamide.

Acetamide is a hepatocarcinogen in rats. We previously revealed that acetamide induces characteristic large micronuclei in rat liver, suggesting the possible involvement of chromosome aberrations in acetamide-induced hepatocarcinogenesis. To elucidate the mechanism of large micronuclei formation, in this study we examined time-dependent changes in rat hepatocytes after administration of acetamide.

Enzymatic hydrolysis of acyl glucuronide metabolites in human liver microsomes correlates to the risk of idiosyncratic drug toxicity.

Acyl glucuronide (AG) is a reactive metabolite that causes idiosyncratic drug toxicity (IDT). Although the instability of AG is used to predict the IDT risk of novel drug candidates, it sometimes overestimates the IDT risk. We investigated whether the rate of enzymatic AG hydrolysis in human liver microsomes (HLM) can predict the risk of IDT.

Association of sleep-wake state discrepancy and depressive symptoms with restorative sleep in patients with depression.

Objective: One of the common symptoms of mood disorders is insomnia, and the recovery processes can be negatively impacted by a lack of restorative sleep. Although factors related to restorative sleep in healthy subjects have been investigated, evaluations of these factors in patients with depression have been rarely done. Patients with depression are known to have sleep-wake state discrepancy, which can further influence their restorative sleep beyond that associated with depressive symptoms.

Identification and quantification of soybean 11S and 7S globulins using RP-UPLC.

Variations in the proportions of the two major soybean [Glycine max (L.) Merr.] seed globulins, glycinin (11S) and β-conglycinin (7S), significantly affect the nutritional and functional properties of soy-based products, but comprehensive methods for the identification and quantification of individual subunits of these proteins are currently lacking.

Quantification of micro- and nano-plastics in atmospheric fine particles by pyrolysis-gas chromatography-mass spectrometry with chromatographic peak reconstruction.

The effects of micro- and nano-plastics (MNPs) on human health are of global concern because MNPs are ubiquitous, persistent, and potentially toxic, particularly when bound to atmospheric fine particles (PM). Traditional quantitative analysis of MNPs by pyrolysis-gas chromatography-mass spectrometry (Py-GC/MS) is often inaccurate because of false positive signals caused by similar polymers and organic compounds. In this study, a reliable analytical strategy combining HNO digestion and chromatographic peak reconstruction was developed to improve the precision of pyrolysis-gas chromatography-mass spectrometry analysis of multiple MNPs bound to PM.

Understanding the Topology Freezing Temperature of Vitrimer-Like Materials through Complementary Structural and Rheological Analyses for Phase-Separated Network.

Vitrimers are sustainable cross-linked polymers characterized by an associative bond exchange mechanism within their network. A well-known feature of vitrimers is the Arrhenius dependence of the viscosity or relaxation time. Another important aspect is the existence of a topology-freezing temperature (), which represents a transition between the viscoelastic solid state and the malleable viscoelastic liquid state.

Alternative approaches for monitoring and evaluation of lymphatic filariasis following mass drug treatment with ivermectin, diethylcarbamazine and albendazole in East New Britain Province, Papua New Guinea.

Background: WHO recommends two annual rounds of mass drug administration (MDA) with ivermectin, diethylcarbamazine, and albendazole (IDA) for lymphatic filariasis (LF) elimination in treatment naïve areas that are not co-endemic for onchocerciasis such as Papua New Guinea (PNG). Whether two rounds of MDA are necessary or sufficient and the optimal sampling strategies and endpoints for stopping MDA remain undefined.

Methods And Findings: Two cross-sectional studies were conducted at baseline (N = 49 clusters or villages) and 12 months after mass drug administration (MDA) with IDA (N = 47 villages) to assess lymphatic filariasis (LF) by circulating filarial antigenemia (CFA) and microfilariae (Mf).

Minimization of the Bacillus subtilis divisome suggests FtsZ and SepF can form an active Z-ring, and reveals the amino acid transporter BraB as a new cell division influencing factor.

Bacterial cytokinesis begins with polymerization of the tubulin homologue FtsZ into a ring-like structure at midcell, the Z-ring, which recruits the late cell division proteins that synthesize the division septum. Assembly of FtsZ is carefully regulated and supported by a dozen conserved cell division proteins. Generally, these proteins are not essential, but removing more than one is in many cases lethal.

M-Sec promotes the accumulation of intracellular HTLV-1 Gag puncta and the incorporation of Env into viral particles.
