Pharmaceutical Research Institute, Albany College of Pharmacy and Health Sciences, Rensselaer, NY 12144, United States. Electronic address:

Receptor-mediated cancer therapy has received much attention in the last few decades. Neuroblastoma and other cancers of the sympathetic nervous system highly express norepinephrine transporter (NET) and cell plasma membrane integrin αvβ3. Dual targeting of the NET and integrin αvβ3 receptors using a Drug-Drug Conjugate (DDC) might provide effective treatment strategy in the fight against neuroblastoma and other neuroendocrine tumors.

Seasonal variation in oestrogenic potency and biological effects of wastewater treatment works effluents assessed using ERE-GFP transgenic zebrafish embryo-larvae.

Aquat Toxicol 2021 May 19;237:105864. Epub 2021 May 19.

Biosciences, College of Life and Environmental Sciences, University of Exeter, Exeter, United Kingdom. Electronic address:

Effluents from wastewater treatment works (WwTW) exhibit both temporal and spatial variation in oestrogenicity, however few studies have attempted to quantify how this variation affects biological responses in fish. Here we used an oestrogen-responsive green fluorescent protein (ERE-GFP) transgenic zebrafish (Danio rerio) to quantify oestrogenic activity and health effects for exposure to three different WwTW effluents. Endpoints measured included survival/hatching rate, GFP induction (measured in target tissues or gfp mRNA induction in whole embryos) and vtg mRNA induction in whole embryos. Read More

Laboratory of Medicinal Chemistry (Associated Unit to CSIC), Department of Pharmacology, Toxicology and Medicinal Chemistry, Faculty of Pharmacy and Food Sciences, Institute of Biomedicine (IBUB), University of Barcelona, Av. Joan XXIII, 27-31, E-08028, Barcelona, Spain. Electronic address:

Recent findings unveil the pharmacological modulation of imidazoline I receptors (I-IR) as a novel strategy to face unmet medical neurodegenerative diseases. In this work, we report the chemical characterization, three-dimensional quantitative structure-activity relationship (3D-QSAR) and ADMET in silico of a family of benzofuranyl-2-imidazoles that exhibit affinity against human brain I-IR and most of them have been predicted to be brain permeable. Acute treatment in mice with 2-(2-benzofuranyl)-2-imidazole, known as LSL60101 (garsevil), showed non-warning properties in the ADMET studies and an optimal pharmacokinetic profile. Read More

Do standard classifications still represent European welfare typologies? Novel evidence from studies on health and social care.

Soc Sci Med 2021 May 29;281:114086. Epub 2021 May 29.

Ca' Foscari, University of Venice, Department of Economics, Fondamenta S. Giobbe - Cannaregio 873, 30121, Venezia, Italy. Electronic address:

Due to the profound changes that have characterised welfare systems, the representativeness of standard welfare classifications such as Esping-Andersen's Three Worlds of Welfare (TWW) have been questioned. In response to concerns that welfare services do not share a common rationale across policy areas, new typologies focused on sub-areas of welfare provision have been introduced. Still, there is little evidence on whether such policy-specific typologies are (i) consistent with the standard TWW classifications; and (ii) consistent across policy areas. Read More

Co-occurring risk and protective factors and regulatory behavior of infants living in low-income homes.

Infant Behav Dev 2021 Jun 9;64:101598. Epub 2021 Jun 9.

Crane Center for Early Childhood Research and Policy, The Ohio State University, United States.

Early self-regulation is a foundation for lifelong wellness and can be shaped by the interplay among several vital exposures. In this study, we examined the emergence of reliable profiles based upon exposure to risk and protective factors in infancy, determined if sociodemographic resources predict profile membership, and determined if these profiles predict early regulatory behaviors in a sample of infants reared in low-income homes. Data were collected from a sample of primarily Black or White mother-infant dyads living in low-income homes in the Midwest (n = 222) during the infants' first year of life (mean maternal age at enrollment: 26.
