First Report of Imported Fire Ants, and X (Hymenoptera: Formicidae) from Kentucky.

Since their introduction into the United States in the early 1900's, imported fire ants, namely Buren (Red Imported Fire Ant), Forel (Black Imported Fire Ant), and their hybrid form X have spread throughout portions of the USA, especially in the southeastern region. Imported fire ants are a serious invasive and economically significant species in the USA and elsewhere, and their spread into new parts of the country is of great concern. Although early models predicted that the fire ants would not be able to survive very far north into the USA, these ants have nonetheless successfully continued their spread into higher latitudes.

Demographic Variation of Wolbachia Infection in the Endangered Mitchell's Satyr Butterfly.

The Mitchell's satyr, , is an endangered species that is limited to highly isolated habitats in the northern and southern United States. Conservation strategies for isolated endangered species often implement captive breeding and translocation programs for repopulation. However, these programs risk increasing the spread of harmful pathogens, such as the bacterial endosymbiont .

Recurrence of prostate cancer in patients receiving testosterone supplementation for hypogonadism.

Purpose: The relationship between recurrent prostate cancer risk and testosterone replacement therapy (TRT) for hypogonadal men is explored.

Summary: The medical literature was searched to identify articles evaluating the use of TRT in symptomatic hypogonadal men with a history of prostate cancer. Eight English-language articles investigating TRT use in hypogonadal men with a history of prostate cancer were analyzed.

Cognitive components of deficit awareness in Alzheimer's disease.

Awareness of deficit was examined in 24 patients with Alzheimer's disease (AD) and their spouses (for a total of 48 participants) using performance prediction-postdiction and questionnaire discrepancy (QD) paradigms. Participants estimated their own memory performances as well the performances of spouses and of a fictional, memory-disordered patient observed on videotape. Patients overpredicted self-performances, but the extent of overestimation decreased for postdictions.
