In this contribution, doping of oriented thin films is investigated for three PBTTT polymers bearing different side chains including linear alkyl ─(CH)─H, single ether ─(CH)─O─(CH)─H and alkyl-siloxane ─(CH)─(Si(CH)O)─Si(CH) A combination of transmission electron microscopy, polarized UV-vis-NIR spectroscopy and transport measurements helps uncover the essential role of the chemical nature of side chains on the efficacy of the doping and on the resulting thermoelectric performances in oriented PBTTT films. Siloxane side chains help to reach record alignment level of PBTTT with dichroic ratio beyond 50 for an optimized rubbing temperature but they impede effective doping of PBTTT crystals with FTCNNQ, resulting in very poor TE properties. By contrast, doping the amorphous phase of all three PBTTTs with magic blue (MB) results in excellent TE performances.

Background: As part of stock enhancement programs for marine fishery species, the stocking of hatchery-produced seedlings into sea areas has been implemented worldwide. DNA markers are vital for responsible stock enhancement practices that aim to conserve the genetic diversity of recipient wild populations. We report novel single-nucleotide polymorphism (SNP) markers and multiplex SNP panels developed for the west Pacific pen shell Atrina lischkeana (Clessin, 1891), a large bivalve that is expected to be a subject of stock enhancement activity as the natural resource has dwindled, especially in Japan.

Background: Intestinal schistosomiasis was confirmed endemic in Mangochi District, Malawi, in May of 2018 following an unexpected encounter with discreet populations of Biomphalaria spp. freshwater snails during routine malacological surveillance activities. Since then, only limited malacological surveillance of Biomphalaria has been carried out, and so the distribution of Biomphalaria populations in this area is currently unclear.

Background: The international health emergency caused by the emergence of the SARS-CoV-2 virus demonstrated the expanding usefulness of multi-country disease outbreak information gathered through event-based surveillance (EBS) as an extension beyond the main purposes of early warning, alert, and response (EWAR). In this article, previous events of multi-country outbreaks from 2010-2019 were reviewed for how EBS, within an expanded sphere of Epidemic Intelligence (EI), may help to enhance the understanding of outbreaks for a more timely and nuanced, multiple-point trigger approach to health emergencies.
Methods: The public, open-source database of ProMed reports were reviewed for the date of first notification on major outbreaks of infectious diseases and then compared for subsequent dates of any new, exceptional epidemiological findings (novel host, settings, transmission characteristics) as a determining factor for prolonged, multi-country events later acknowledged on the WHO disease outbreak news (DON) website, or by peer-reviewed journal publication if no related DON information became available.

Endocannabinoids, signaling through the cannabinoid CB1 receptor (CB1R), regulate several forms of neuronal plasticity. CB1Rs in the developing primary visual cortex (V1) play a key role in the maturation of inhibitory circuits. Although CB1Rs were originally thought to reside mainly on presynaptic axon terminals, several studies have highlighted an unexpected role for astrocytic CB1Rs in endocannabinoid mediated plasticity.
