Dioxin-like polychlorinated biphenyls (dl-PCB) in hydrochars and biochars: Review of recent evidence, pollution levels, critical gaps, formation mechanisms and regulations.

Contamination of chars with dioxin-like polychlorinated biphenyls (dl-PCB) significantly limits their use and hinders their deployment in the circular bioeconomy, specifically in applications that may lead to dietary exposure. Here, for the first time, we review the levels of contamination of chars produced from pyrolysis and hydrothermal carbonisation (HTC) with dl-PCB congeners. We conduct a detailed and critical examination of the role played by the processing parameters, such as temperature and residence time, and the reaction mechanisms, to detoxify the biomass under an oxygen-free atmosphere during its valorisation.

The effect of ovariectomy, 17β-estradiol treatment, and progesterone treatment on dopaminergic regulation of prepulse inhibition in adult and adolescent female mice.

The aim of the present study was to investigate the role of ovarian hormones on dopaminergic regulation of prepulse inhibition (PPI), a measure of sensorimotor gating deficient in schizophrenia and other psychiatric illnesses. Either in adulthood (11 weeks of age) or adolescence (5 weeks of age), female mice underwent ovariectomy (OVX) and were implanted with 17β-estradiol, progesterone, or a combination of these hormones. All mice were tested in adulthood for the acute effect of the dopamine receptor agonist, apomorphine, on PPI.

The renewal reducing effect of unpaired unconditional stimuli presented during extinction is not specific to the unconditional stimulus used during acquisition.

Presenting unpaired unconditional stimuli (US) during extinction training reduces the renewal of conditional fear due to context change. The present study investigated whether this reduced return of fear is specific to the aversive US presented during acquisition or can also be observed after extinction with unpaired presentations of another aversive or of a non-aversive US. Using an ABA renewal paradigm that trained extinction in a context different from that of the acquisition, renewal and re-acquisition test phases, participants received five unpaired presentations of either the aversive US used during acquisition (Group Aversive-Same), an aversive US not presented during acquisition (Group Aversive-Different) or a non-aversive US (Group Non-aversive) during extinction training.

Medical ambivalence and Long Covid: The disconnects, entanglements, and productivities shaping ethnic minority experiences in the UK.

Structural violence - related to 'isms' like racism, sexism, and ableism - pertains to the ways in which social institutions harm certain groups. Such violence is critical to institutional indifference to the plight of ethnic minority people living with long-term health conditions. With only emergent literature on the lived experiences of ethnic minorities with Long Covid, we sought to investigate experiences around the interplay of illness and structural vulnerabilities.

Acid-Enhanced Photoiniferter Polymerization under Visible Light.

Photoiniferter (PI) is a promising polymerization methodology, often used to overcome restrictions posed by thermal reversible addition-fragmentation chain-transfer (RAFT)  polymerization. However, in the overwhelming majority of reports, high energy UV irradiation is required to effectively trigger photolysis of RAFT agents and facilitate the polymerization, significantly limiting its potential, scope, and applicability. Although visible light PI has emerged as a highly attractive alternative, most current approaches are limited to the synthesis of lower molecular weight polymers, and typically suffer from prolonged reaction times, extended induction periods, and higher dispersities.

Advanced Bionic 3D Interfacial Solar Steam Generator With One-way Water Supply for Highly Efficient Desalination and Oil-Fouling Prevention.

Self-maintenance of zonal hepatocytes during adult homeostasis and their complex plasticity upon distinct liver injuries.

Hepatocytes are organized into distinct zonal subsets across the liver lobule, yet their contributions to liver homeostasis and regeneration remain controversial. Here, we developed multiple genetic lineage-tracing mouse models to systematically address this. We found that the liver lobule can be divided into two major zonal and molecular hepatocyte populations marked by Cyp2e1 or Gls2.

Urothelial carcinoma in situ with "early papillary formation" vs "lateral spread/shoulder lesion" of prior high-grade noninvasive papillary urothelial carcinoma: A survey of pathologist and urologist interpretations.

Objectives: Urothelial carcinoma in situ (CIS) with early papillary formation is terminology sometimes used to suggest incipient high-grade papillary urothelial carcinoma (PUC) but may lead to confusion between true CIS and lateral flat spread of PUC.

Methods: It remains unclear how pathologists and urologists interpret this scenario, so a survey was circulated to 68 pathologists (group 1 = 28 academic genitourinary pathologists; group 2 = 17 pathologists with a self-reported genitourinary focus; group 3 = 23 pathologists self-reported as not genitourinary specialists) and 32 urologists.

Results: Regarding atypical urothelial lesions that appear mainly flat but contain possible papillae, group 3 was more likely to label this as CIS compared with groups 1 and 2 (35% for group 3 vs 13% for groups 1 and 2), while groups 1 and 2 more often adopted another descriptive diagnosis, such as "CIS with early papillary features" (38% for groups 1 and 2 vs 13% for group 3).
