Anticancer agents featuring hybrid molecules can improve effectiveness and diminish drug resistance. The current study aimed to introduce newly synthesized heterocyclic steroids of promising anticancer effects loaded in polyethylene glycol (PEG)•based nanoparticles form. Several heterocyclic steroids (1-9) were synthesized via multicomponent reactions (MCRs) and confirmed via the analytical and spectral data. Compounds 1, 2, 3, 4, 5, 6, 7 and 9, were investigated individually in their free and PEG based nano-size hybrid forms as anticancer agents against three human cell lines: hepatocellular carcinoma cells (HepG2); breast cancer cells (MCF-7); and colon cancer cells (HCT116)...

The transfer of immunity from mother to offspring is a central way to endow the offspring with increased protection against pathogens. This phenomenon is not only found within the vertebrate domain: in some circumstances, invertebrate mothers can also give their offspring an immune kick-start, which is termed trans-generational immune priming (TGIP). TGIP has been uncovered for a number of invertebrate species, but it is not ubiquitously evident. The reasons for which are not known. In this issue of Molecular Ecology, Tate, Andolfatto, Demuth, and Graham () probe the molecular underpinnings of TGIP in concert with the temporal dynamics of the response in the red flour beetle, Tribolium castaneum, infected with the bacterium Bacillus thuringiensis (Figure )...

Selection has a deep impact on the distribution of genetic diversity and population differentiation along the genome (the genomic landscapes of diversity and differentiation), reducing diversity and elevating differentiation not only at the sites it targets, but also at linked neutral sites. Fuelled by the high-throughput sequencing revolution, these genomic footprints of selection have been extensively exploited over the past decade with the aim to identify genomic regions involved in adaptation and speciation...

Transition path sampling techniques are becoming common approaches in the study of rare events at the molecular scale. More efficient methods, such as transition interface sampling (TIS) and replica exchange transition interface sampling (RETIS), allow the investigation of rare events, for example, chemical reactions and structural/morphological transitions, in a reasonable computational time. Here, we present PyRETIS, a Python library for performing TIS and RETIS simulations. PyRETIS directs molecular dynamics (MD) simulations in order to sample rare events with unbiased dynamics...

REVIEW
Mohaddese Maghsudlu, Ehsan Farashahi Yazd
Esophageal cancer as the sixth common cause of cancer death in the world consists of different histological types with various incidence patterns. Among them, esophageal adenocarcinoma and esophageal squamous cell carcinoma are the most prevalent types which also have different causality, cell of origin and risk factors. Since epidemiological studies have announced consumption of hot substances as one of the major risk factors for squamous cell carcinoma, evaluating the effect of this external stress on esophagus cells seems desirable...

In recent decades, extensive studies have been devoted to assembling nanoparticles (NPs) into various ordered structures to achieve novel optical properties. It however still remains a challenging task to assemble NPs into cyclic one-dimensional (1D) shapes such as rings and frames. In this work, we report a directed assembly method to precisely assemble NPs into well-defined, free-standing frames using polymer single crystals (PSCs) as the template. Preformed poly(ethylene oxide) (PEO) single crystals were used as the template to direct the crystallization of block copolymer (BCP) poly(ethylene oxide)-b-poly(4-vinylpyridine) (PEO-b-P4VP), which directed gold NPs (AuNPs) to form AuNP frames...

OBJECTIVE: To support a national initiative to remove sugary drinks from schools and limit drinks to water or unflavoured milk ('water-only'). METHODS: We emailed all 201 schools with primary school aged children in the Greater Wellington region with a survey on (1) current status of, (2) support needs for, and (3) barriers to or lessons learned from, a 'water-only' school policy. RESULTS: Only 78 (39%) of schools responded. Most supported 'water-only': 22 (28%) had implemented a policy; 10 (13%) in process of doing so; 22 (28%) were considering it; and 12 (15%) were 'water-only', but did not have a policy...

In plant, a few 22 nt miRNAs direct cleavages of their targets and trigger the biogenesis of phased small interfering RNAs (phasiRNAs) in plant. In this study, we characterized a miRNA triggering phasiRNAs generation, miR3954, and explored its downstream target genes and potential function. Our results demonstrated that miR3954 showed specific expression in the flowers of citrus species and it targeted a NAC transcription factor (Cs7g22460) and two non-coding RNA transcripts (lncRNAs, Cs1g09600 and Cs1g09635)...

Generalized Born (GB) solvent models are common in acid/base calculations and protein design. With GB, the interaction between a pair of solute atoms depends on the shape of the protein/solvent boundary and, therefore, the positions of all solute atoms, so that GB is a many-body potential. For compute-intensive applications, the model is often simplified further, by introducing a mean, native-like protein/solvent boundary, which removes the many-body property. We investigate a method for both acid/base calculations and protein design that uses Monte Carlo simulations in which side chains can explore rotamers, bind/release protons, or mutate...

We report high-energy-resolution X-ray absorption spectroscopy detection of ethylene and CO ligands adsorbed on catalytically active iridium centers isolated on zeolite HY and on MgO supports. The data are supported by density functional theory and FEFF X-ray absorption near-edge modelling, together with infrared (IR) spectra. The results demonstrate that high-energy-resolution X-ray absorption spectra near the iridium LIII (2p3/2 ) edge provide clearly ascribable, distinctive signatures of the ethylene and CO ligands and illustrate effects of supports and other ligands...
