Engaging Adults With Chronic Disease in Online Depressive Symptom Self-Management.

The main purpose of this study was to evaluate participant engagement and effects of an Internet-based, self-directed program for depressive symptoms piloted among adults with a chronic disease. Eligible participants ( N = 47) were randomly assigned to either the "Think Clearly About Depression" online depression self-management program or the control group. The Patient Health Questionnaire-8 and Chronic Disease Self-Efficacy Scales were administered at baseline and at Weeks 4 and 8 after initiating the intervention.

The color of mass culture: spectral characteristics of a shallow water column through shade-limited algal growth dynamics(1).

It is envisioned that mass algal cultivation for commercial biofuels production will entail the use of large raceway pond systems, which typically have shade-limited photosynthetic growth within depths of 20-30 cm. The attenuation of light and spectral qualities of red, green, and blue wavelengths in a 20-cm water column as a function of Chl-a concentration during exponential and linear phases of growth dynamics for the marine diatom Thalassiosira pseudonana was examined under laboratory conditions. While photosynthetically available radiation (PAR) was in excess throughout the water column during the phase of exponential growth, PAR became rate limiting differently for red, green, and blue wavelengths during the phase of linear growth.

Castration eliminates conspecific aggression in group-housed CD1 male surveillance mice (Mus musculus).

Microbiologic surveillance is essential for murine health maintenance. At our institution, female progeny of inhouse-bred CD1 mice are used in both the transgenic facility and health-surveillance program. To reduce overall animal use, the male progeny, otherwise slated for euthanasia due to a lack of utility, also were enrolled as sentinels.

Prevalence of murine Helicobacter spp. Infection is reduced by restocking research colonies with Helicobacter-free mice.

Most academic research colonies of mice are endemically infected with enterohepatic Helicobacter spp. (EHS). We evaluated EHS prevalence in surveillance mice before and after a 10-y period of requiring that imported mice be free of EHS by embryo transfer rederivation or purchase from approved vendors.

Intra-articular therapy to treat septic arthritis in a dog.

A 6 yr old female spayed Labrador retriever was examined for severe pain and a nonweight-bearing right forelimb lameness due to swelling and wounds with direct communication into the elbow joint. The medical management of β hemolytic Streptococcus septic arthritis with needle lavage of the joint, systemic and local antibiotic therapy, and analgesic therapy is described. This case provides information on the need to address septic arthritis in the dog as an emergency situation and the treatment with intra-articular medication.
