Evaluation of the South American gastropod Heleobia parchappii as test organism in cadmium toxicity bioassays

open access: yesEcología Austral, 2023
Gastropods are abundant key components in freshwater ecosystems, many of which are affected by anthropogenic activities. The genus Heleobia is widely distributed across Argentina, and the native Heleobia parchappii is very common in the Pampean Region ...

The activity of the pyrrole insecticide chlorfenapyr in mosquito bioassay: towards a more rational testing and screening of non-neurotoxic insecticides for malaria vector control

open access: yesMalaria Journal, 2015
BackgroundThe rapid selection of pyrethroid resistance throughout sub-Saharan Africa is a serious threat to malaria vector control. Chlorfenapyr is a pyrrole insecticide which shows no cross resistance to insecticide classes normally used for vector ...

Prevention of Fab-arm exchange and antibody reduction via stabilization of the IgG4 hinge region

open access: yesmAbs, 2020
IgG4s are dynamic molecules that undergo a process called Fab-arm exchange. Disulfide bonds between heavy chains are transiently reduced, resulting in half antibodies that reform intact antibodies with other IgG4 half antibodies.

Effect of photoperiod and host distribution on the horizontal transmission of Isaria fumosorosea (Hypocreales: Cordycipitaceae) in greenhouse whitefly assessed using a novel model bioassay [PDF]

open access: yes, 2010
A model bioassay was used to evaluate the epizootic potential and determine the horizontal transmission efficiency of Isaria fumosorosea Trinidadian strains against Trialeurodes vaporariorum pharate adults under optimum conditions (25±0.5°C, ~100% RH ...

Liposome-Based Bioassays [PDF]

open access: yesBiology, 2020
This review highlights the potential of using liposomes in bioassays. Liposomes consist of nano- or micro-sized, synthetically constructed phospholipid vesicles. Liposomes can be loaded with a number of reporting molecules that allow a dramatic amplification of the detection threshold in bioassays.

Susceptibility of Myzus persicae, Brevicoryne brassicae and Nasonovia ribisnigri to fungal biopesticides in laboratory and field experiments [PDF]

open access: yes, 2020
The aim of this study was to evaluate the potential of entomopathogenic fungi (EPF) for the control of aphid pests of field vegetable crops. Four biopesticides based on the EPF Beauveria bassiana (Botanigard ES and Naturalis L), Cordyceps fumosorosea s.l.

A Human Kidney Tubuloid Model of Repeated Cisplatin‐Induced Cellular Senescence and Fibrosis for Drug Screening

open access: yesAdvanced Healthcare Materials, EarlyView.
Replicating aging and senescence‐related pathophysiological responses in kidney organoids remains a significant challenge. Human adult renal tubular organoid, tubuloids, are successfully developed recapitulating cellular senescence that is the central pathophysiological mechanism of chronic kidney disease (CKD).

Open windrow composting of polymers: An investigation into the rate of degradation of polyethylene [PDF]

open access: yes, 2004
The compostability of degradable polymers under open windrow composting conditions is explored within this paper. Areas for consideration were the use of, and impacts of, degradable polyethylene (PE) sacks on the composting process and the quality of the
