Prevalence of SARS-CoV-2 Infection Among Health Care Workers in a Tertiary Community Hospital.

This cross-sectional study assesses the rate of COVID-19 infection among health care workers in a large community hospital.

Detection of human papillomavirus DNA in biopsy-proven cervical squamous intraepithelial lesions in pregnant women.

This study analyzed cervical squamous intraepithelial lesions (SILs) in pregnant women for human papillomavirus (HPV) using in situ hybridization analysis. HPV DNA was detected in 77% (23/30) of low-grade SILs as compared to 89% of such lesions in nonpregnant women. The detection rate in high-grade SILs was 41% (9/22) compared to 70% in nonpregnant women.

Postpartum aggression and plasma prolactin levels in mice exposed to lead.

Young-adult, female Binghamton Heterogeneous Stock (HET) mice either were exposed to lead via drinking water from birth, or not. Eight days after giving birth to their first litter of pups (at about 70-75 days of age), postpartum aggression tests were conducted. Unfamiliar Het male intruders were introduced to the primiparous dams' nesting cages, and dyadic behavioral interactions were observed for 10 min.

Pulmonary agenesis association with nonimmune hydrops.

Bilateral pulmonary agenesis is a rare malformation with 13 cases previously reported. To our knowledge, none of these cases have been associated with hydrops fetalis. We report a 36 weeks, hydropic female infant (46XX) with bilateral pulmonary agenesis, unilateral microophthalmia, and bilateral renal dysplasia.

Lead, age and aggression in male mice.

The impact of eleven weeks of ingestion of a 0.5% lead acetate solution on agonistic behavior of male Binghamton Heterogeneous stock mice (either 120 or 660 days of age) was examined. Similar aged mice were paired for aggression testing.

Lead exposure and agonistic behavior of adult mice of two ages.

Adult male Heterogeneous stock (HET) mice were exposed to a 0.5% lead acetate solution when they were either 65 or 330 days of age. Fifteen weeks later they were paired with same age (young or old) water control HET mice and tested for aggression.

Influence of environmental rearing history and postsurgical environmental change on the septal rage syndrome in mice.

Reactivity to handling was examined in Binghamton Heterogeneous (HET) mice given septal lesions or control surgery following 5 weeks of postweaning rearing in enriched or restricted environments. Three housing conditions were employed: continuous enrichment, continuous restriction (both pre- and postsurgically), and a group switched from environmental enrichment to restriction 24 hours after surgery. The restricted mice were more reactive to handling than the enriched mice presurgically (60 days old), and interactions of housing conditions and surgery were found over the seven day postsurgical handling and testing period.
