Distracted driving is responsible for nearly 1 million crashes each year in the United States alone, and a major source of driver distraction is handheld phone use. We conducted a randomized, controlled trial to compare the effectiveness of interventions designed to create sustained reductions in handheld use while driving (NCT04587609). Participants were 1,653 consenting Progressive® Snapshot® usage-based auto insurance customers ages 18 to 77 who averaged at least 2 min/h of handheld use while driving in the month prior to study invitation.

Objective: To test whether interventions involving social comparison feedback and/or financial incentives can reduce drivers' handheld phone use.
Tetrachlorvinphos (TCVP) is the pesticidal active ingredient found in some flea and tick collars for dogs and cats. Recent studies sponsored by The Hartz Mountain Corporation, confirm the safety of TCVP as an active ingredient in pet collars. Based upon data from these new studies and results previously relied upon by the U.

Background: Recent reports indicated that increasing the monthly oral dosage and the number of consecutive monthly doses of moxidectin improved the efficacy against macrocyclic lactone (ML)-resistant Dirofilaria immitis. The two laboratory studies reported here evaluated the efficacy of four or six monthly oral doses of 24 µg/kg moxidectin compared to six monthly doses of either Heartgard® Plus (ivermectin/pyrantel) or Interceptor® Plus (milbemycin oxime/praziquantel) against ML-resistant D. immitis strains.

Methods: Laboratory studies were conducted against two different strains of each tick species. In each study, 10 purpose-bred Beagle or mixed-breed dogs were randomly allocated to one of two treatment groups based on pre-treatment host-suitability tick counts.
Background: The black-legged (or deer) tick, Ixodes scapularis, commonly infests dogs in the USA and is the vector of important zoonotic pathogens, including Borrelia burgdorferi, the causative agent of Lyme disease. Rapid onset of activity is important in reducing the feeding activity of ticks, thereby reducing the possibility of transmission of infections. The speed of kill of a novel oral combination product, Simparica Trio™ containing sarolaner, moxidectin and pyrantel was evaluated in a well-controlled laboratory study against an existing infestation and subsequent weekly induced infestations of I.

Methods: Based on pre-treatment flea counts, dogs were randomly allocated to treatment with a single, oral dose of either placebo or Simparica Trio™ at the minimum label dose of 1.2 mg/kg sarolaner, 24 µg/kg moxidectin and 5 mg/kg pyrantel (as pamoate salt) on Day 0.
The speed of kill of a novel, topical product containing selamectin in combination with sarolaner (selamectin/sarolaner; Revolution Plus/Stronghold Plus) was evaluated against Ixodes scapularis ticks on cats. Sixteen cats were randomly allocated to a treatment group and treated topically on Day 0 with either placebo (vehicle control) or 6 mg/kg selamectin plus 1 mg/kg sarolaner. Cats were infested with approximately 50 unfed viable adult I.

In each study, cats were randomly allocated to treatment groups based on pre-treatment host-suitability tick counts. On Days -2, 5, 12, 19, 26 and 33, the cats were infested with unfed adult ticks.

Ten male and ten female adult domestic shorthair cats were randomly assigned to one of two treatment groups based on pre-treatment flea counts. Cats received topical treatment on Day 0 in a single spot to the dorsal scapular area with either a placebo formulation or with the combination formulation at the minimal dose of 6.

The homoleptic organocerium complex Ce{C(SiHMe ) } (1) reacts with B(C F ) to produce the zwitterionic bis(alkyl) hydridoborato Ce{C(SiHMe ) } HB(C F ) (2). NMR and IR spectroscopy and X-ray crystallography indicate that each alkyl ligand contains two bridging Ce↼H-Si interactions in both 1 and 2. Compound 2 serves as a precatalyst for the hydrosilylation of acrylates to give α-silyl esters at room temperature with a turnover number of 2200.

Methods: Six negative-controlled studies were conducted, involving a total of 112 adult dogs (57 mixed breed, 47 Beagles, eight Labradors). In each study, dogs were randomized to two groups of eight to ten dogs each.
The efficacy of a single oral dose of a novel isoxazoline, sarolaner (Simparica™, Zoetis), for the treatment and control of flea infestations on dogs was confirmed in five laboratory studies. The studies were conducted using adult purpose-bred Beagles and/or mixed breed dogs. All animals were individually identified and housed, and were allocated randomly to treatment with either placebo or sarolaner (eight to 10 per group) based on pretreatment parasite counts.

A parasiticide's speed of kill is important to minimize the direct and deleterious effects of tick infestation and especially to reduce the risk of transmission of tick-borne pathogens.

The rapid speed of kill of a parasiticide is important to alleviate the direct deleterious effects of fleas, reduce the impact of allergic responses, and break the flea life cycle. In this study, the speed of kill of a novel orally administered isoxazoline parasiticide, sarolaner (Simparica) against fleas on dogs was evaluated and compared with spinosad in combination with milbemycin oxime (Trifexis) for 5 weeks after a single oral dose.
