Pb can damage the physiological function of human organs by entering the human body via food-chain enrichment. Revealing the mechanisms of maize tolerance to Pb is critical for preventing this. In this study, a Pb-tolerant maize inbred line, 178, was used to analyse transcription factors (TFs) expressed under Pb stress based on RNA sequencing data. A total of 464 genes expressed in control check (CK) or Pb treatment samples were annotated as TFs. Among them, 262 differentially expressed transcription factors (DETs) were identified that responded to Pb treatment...

Ethungshan Shitiri, In-Seop Park, Ho-Shin Cho
This paper proposes a hybrid medium access protocol named orthogonal coded medium access control (OrMAC), which extends the principle of distributed queuing collision avoidance protocol (DQCA) of wireless local area network (WLAN) to delay-sensitive machine-to-machine (M2M) networks. OrMAC pre-assigns orthogonal codes, which serve as the channel contention signals, to the nodes entering the network. The "pre-assignment" eliminates contention collisions since it guarantees that no two nodes share the same contention code...

The embryos of some angiosperms (usually referred to as chloroembryos) contain chlorophylls during the whole period of embryogenesis. Developing embryos have photochemically active chloroplasts and are able to produce assimilates, further converted in reserve biopolymers, whereas at the late steps of embryogenesis, seeds undergo dehydration, degradation of chlorophylls, transformation of chloroplast in storage plastids, and enter the dormancy period. However, in some seeds, the process of chlorophyll degradation remains incomplete...

This work reports on the variation in wastewater treatment works (WwTW) influent concentrations of a wide variety of active pharmaceutical ingredients (APIs), their removal efficiency, effluent concentrations and potential risks to the aquatic environment. The research is based on data generated from two large UK-wide WwTW monitoring programmes. Taking account of removal of parent compound from the aqueous phase during treatment in combination with estimates of dilution available it is possible to prioritise the APIs of greatest risk of exceeding estimates of predicted no effect concentrations (PNEC) in receiving waters for all WwTW in the UK...

Anthony T Zimmer, HakSoo Ha
Although an explosion of new building materials are being introduced into today's market, adequate up-front research into their chemical and physical properties as well as their potential health and environmental consequences is lacking. History has provided us with several examples where building materials were broadly deployed into society only to find that health and environmental problems resulted in unintended sustainability consequences. In the following paper, we use lead and asbestos as legacy building materials to show their similar historical trends and sustainability consequences...

Humans can be exposed to pathogens from poorly managed animal feces, particularly in communities where animals live in proximity to humans. This systematic review of peer-reviewed and grey literature examines the human health impacts of exposure to poorly managed animal feces transmitted via water, sanitation, and hygiene (WASH)-related pathways in low- and middle-income countries where household livestock, small-scale animal operations, and free-roaming animals are common. We identify routes of contamination by animal feces, control measures to reduce human exposure, and propose research priorities for further inquiry...

Aromatase catalyses the biosynthesis of estrogens from androgens. Due to the physiological importance of this conversion of lipophilic substrates, the interaction with the lipid bilayer for this cytochrome P450 is crucial for its dynamics that must allow an easy access to substrates and inhibitors. Here, aromatase-anastrozole interaction is studied combining computational methods to identify possible access/egress routes with the protein inserted in the membrane and experimental tools aimed at the investigation of the effect of the inhibitor on the protein conformation...

Background Finding innovative and cost-efficient care strategies that induce long-term health benefits in cardiac patients constitutes a big challenge today. The aim of this Telerehab III follow-up study was to assess whether a 6-month additional cardiac telerehabilitation programme could induce long-term health benefits and remain cost-efficient after the tele-intervention ended. Methods and results A total of 126 cardiac patients first completed the multicentre, randomised controlled telerehabilitation trial (Telerehab III, time points t0 to t1)...

BACKGROUND: Oral immunosuppressive drugs are frequently prescribed in young women with atopic dermatitis (AD). Immunocompromised patients may have a higher risk of developing high risk HPV infections, CIN and cervical carcinoma. Most literature on patients using oral immunosuppressive drugs is available in organ transplant patients. Literature on the risk of developing cervical carcinoma in AD patients treated with oral immunosuppressive drugs is lacking. At this moment there is no clear guideline/consensus on this topic, but in daily practice, questions arise concerning whether this risk is increased and whether more intensive screening in women using immunosuppressive drugs should take place...

The enteric nervous system (ENS) controls the function of the gastrointestinal tract and has been implicated in various diseases, including Parkinson's disease (PD). PD is a neurodegenerative disease with Lewy bodies (LBs) and Lewy neurites (LNs) as the main pathological features. In addition to the typical motor symptoms in PD, attention has been drawn to non-motor symptoms, such as constipation, implying dysfunction of the ENS. In the present study, we characterized the age-dependent morphological alterations and aggregation of α-synuclein (α-syn), the primary protein component in LBs and LNs, in the ENS in an α-syn transgenic mouse model...

BACKGROUND: The timing of intestinal failure (IF) surgery has changed. Most specialized centers now recommend postponing reconstructive surgery for enteric fistula and emphasize that abdominal sepsis has to be resolved and the patient's condition improved. Our aim was to study the outcome of postponed surgery, to identify risk factors for recurrence and mortality, and to define more precisely the optimal timing of reconstructive surgery. METHODS: PubMed, Embase, and the Cochrane Library were systematically reviewed on the outcomes of reconstructive IF surgery (fistula recurrence, mortality, morbidity, hernia recurrence, total closure, enteral autonomy)...

Bacterial protein toxins became valuable molecular tools for the targeted modulation of cell functions in experimental pharmacology and attractive therapeutics because of their potent and specific mode of action in human cells. C2IN-C3lim, a recombinant fusion toxin (~50 kDa) of the Rho-inhibiting C3lim from Clostridium (C.) limosum and a non-toxic portion of the C. botulinum C2 toxin (C2IN), is selectively internalized into the cytosol of monocytic cells where C3lim specifically ADP-ribosylates Rho A and -B, thereby inhibiting Rho-mediated signaling...

Most of the anticancer drug candidates entering preclinical trials fail to be approved for clinical applications. The following are among the main causes of these failures: studying molecular mechanisms of cancer development, identifying therapeutic targets, and testing drug candidates using inappropriate tissue culture models, which do not recapitulate the native microenvironment where the cancer cells originate. It has become clear that three-dimensional (3D) cell cultures are more biologically and clinically relevant than 2D models...

Toll-like receptor 4 (TLR4) is a pro-inflammatory cascade initiator in post-stroke inflammation. In this study, miR-1906, a novel regulator of TLR4, was identified via in silico analysis and microRNA profiling in male adult mice, and its expression was then quantitated in the ischemic hemisphere. We found miR-1906 to be significantly brain-enriched in the ischemic hemisphere and even more drastically enriched in the peri-infarct regions. Furthermore, in vitro experiments demonstrated that during oxygen-glucose deprivation (OGD), miR-1906 expression was increased in glial cells but decreased in neurons...
