Colloidal Stabilization of Sodium Dilauraminocystine for Selective Nanoparticle-Nanoparticle Interactions: Their Screening and Extraction by Iron Oxide Magnetic Nanoparticles.

Nanoparticle-nanoparticle (NP-NP) interactions between Au and Ag NPs were studied by using sodium dilauraminocystine (SDLC)- and Gemini surfactant-stabilized NPs to demonstrate the unique NP surface adsorption behavior of SDLC in controlling and mimicking such interactions in complex mixtures. They were significantly affected by the spacer as well as the polymeric nature of the head group of Gemini surfactants. A longer spacer impeded while a polymeric head group facilitated the interactions.

Optimization of planting dates of Jalapeno pepper (Capsicum annuum 'Jalapeño' L.) and cantaloupe (Cucumis melo var. cantalupensis Ser.) relay cropped with strawberry (Fragaria × ananassa Duchesne).

Florida strawberry growers frequently relay-crop (RC) vegetables with strawberry to offset high input costs. Relay-cropping consists of planting two crops at different times on the same raised bed which helps growers' lower risk due to diversification and maximize economic returns. Four separate experiments on relay cropping strawberry with jalapeño pepper and cantaloupe were conducted at Balm, Florida, in 2016-17 and 2017-18.

PACAP intraperitoneal treatment suppresses appetite and food intake via PAC1 receptor in mice by inhibiting ghrelin and increasing GLP-1 and leptin.

Pituitary adenylate cyclase-activating peptide (PACAP) is expressed within the gastroenteric system, where it has profound physiological effects. PACAP was shown to regulate food intake and thermogenesis centrally; however, PACAP peripheral regulation of appetite and feeding behavior is unknown. Therefore, we studied PACAP's effect on appetite and food intake control by analyzing feeding behavior and metabolic hormones in PAC1-deficient (PAC1-/-) and age-matched wild-type (WT) mice intraperitoneally injected with PACAP1-38 or PACAP1-27 before the dark phase of feeding.

Mechanism of sperm immobilization by Escherichia coli.

Aim: To explore the influence of Escherichia coli on the motility of human spermatozoa and its possible mechanism.

Methods: Highly motile preparations of spermatozoa from normozoospermic patients were coincubated with Escherichia coli for 4 hours. At 1, 2 and 4 hours of incubation, sperm motility was determined.
