Non-Small Cell Lung Cancer Imaging Using a Phospholipase A2 Activatable Fluorophore.

Lung cancer, the most common cause of cancer-related death in the United States, requires advanced intraoperative detection methods to improve evaluation of surgical margins. In this study we employed DDAO-arachidonate (DDAO-A), a phospholipase A2 (PLA2) activatable fluorophore, designed for the specific optical identification of lung cancers in real-time during surgery. The fluorescence activation of DDAO-A by porcine sPLA2 was tested in various liposomal formulations, with 100 nm extruded EggPC showing the best overall characteristics.

Rare diagnosis of intraosseous lipoma in the scapula of a 15-year-old domestic shorthair cat.

Case Summary: A 15-year-old male castrated domestic shorthair cat originally presented to its primary care veterinarian with a chief complaint of a multi-month history of decreased appetite, weight loss and mild weight-bearing lameness. On physical examination, over the right scapula there was mild-to-moderate muscle wasting and a palpable firm, bony mass measuring approximately 3.5 cm × 3 cm.

Evaluation of outcomes following subtotal colectomy for the treatment of idiopathic megacolon in cats.

Objective: To evaluate outcomes in cats undergoing subtotal colectomy for the treatment of idiopathic megacolon and to determine whether removal versus nonremoval of the ileocecocolic junction (ICJ) was associated with differences in outcome.

Animals: 166 client-owned cats.

Procedures: For this retrospective cohort study, medical records databases of 18 participating veterinary hospitals were searched to identify records of cats with idiopathic megacolon treated by subtotal colectomy from January 2000 to December 2018.

Rape myth acceptance of students: The influence of social groups.

The purpose of the study was two-fold. The first objective was to determine the level of rape myth acceptance of college students. The second objective was to determine the impact of social group membership on rape myth.

Effects of osteoarthritis on radiographic measures of laxity and congruence in hip joints of Labrador Retrievers.

OBJECTIVE- To determine effects of hip joint osteoarthritis on radiographic measures of hip joint laxity and congruence. DESIGN- Longitudinal study. ANIMALS- 40 Labrador Retrievers.

Technique and outcome of nares amputation (Trader's technique) in immature shih tzus.

Dogs with brachycephalic conformation frequently suffer from stenotic nares. This study investigated the clinical effects of stenotic nares resection in shih tzu puppies using an amputation technique first described in 1949. The authors hypothesized that surgical correction of the stenotic nares would result in improvement of nasal discharge/noise, breathing difficulty (dyspnea), and exercise limitations (exercise intolerance), and that the technique would provide a cosmetic result.
