The effect of delta-9 tetrahydrocannabinol and methamphetamine on sustained attention in the jumping spider (Trite planiceps).

Decreasing responsiveness to repeated visual stimuli (i.e., the inability to sustain attention) in jumping spiders (Salticidae) parallels that found in humans.

Impact of a nutritional immunomodulator in dry cows heat stressed with an electric blanket model.

Heat stress (HT) in the dry period reduces yield and health in the next lactation. Previous work indicates that feeding OmniGen-AF® (OMN) mitigates the detrimental effects of HT. Electric blankets (EB) can induce heat stress in lactating cows, but EB have not been used with dry cows.

The effect of interstimulus interval on sustained attention.

The ability of nervous systems to filter out irrelevant and repetitive stimuli may prevent animals from becoming 'saturated' with excess information. However, animals must be particular about which stimuli to attend to and which to ignore, as mistakes may be costly. Using a comparative approach, we explored the effect of interstimulus interval (ISI) between repeated presentations of visual stimuli presented on a screen to test the decrease in responses (response decrement) of both Trite planiceps jumping spiders and untrained Columba livia pigeons, animals with comparable visual ability despite having structurally different visual systems and brain size.

Quantitative SPECT/CT Metrics in Early Prediction of [Lu]Lu-DOTATATE Treatment Response in Gastroenteropancreatic Neuroendocrine Tumor Patients.

Our objective is to explore quantitative imaging markers for early prediction of treatment response in patients with gastroenteropancreatic neuroendocrine tumors (GEP-NETs) undergoing [Lu]Lu-DOTATATE therapy. By doing so, we aim to enable timely switching to more effective therapies in order to prevent time-resource waste and minimize toxicities. Patients diagnosed with unresectable or metastatic, progressive, well-differentiated, receptor-positive GEP-NETs who received 4 sessions of [Lu]Lu-DOTATATE were retrospectively selected.

Effects of Dietary Inclusion of a Proprietary Combination of and on Intestinal Permeability and Immune Response in Broiler Chickens during a Coccidia Challenge.

This study assessed the impact of Magni-Phi Ultra (MPU) inclusion on intestinal integrity and immunity in broiler chickens challenged with coccidia during peak and recovery phases. A total of 128 male Ross 708 broiler chicks were randomly allotted to one of four treatment groups (four chicks/cage). Treatments included an uninfected control (UUC); a coccidial challenge (CC) infected control (IUC); a CC fed salinomycin at 66 ppm (SAL); and a CC fed Magni-Phi Ultra at 0.
