Does cranberry have a role in catheter-associated urinary tract infections?

Introduction: Catheter-associated urinary tract infections (CA-UTIs) are a prevalent and costly condition, with very few therapeutic options. We sought to evaluate the efficacy of an oral cranberry supplement on CA-UTIs over a six-month period.

Methods: Subjects with long-term indwelling catheters and recurrent symptomatic CA-UTIs were enrolled to take a once-daily oral cranberry supplement with 36 mg of the active ingredient proanthocyanidin (PACs).

Robotic-assisted cystogastrostomy for a patient with a pancreatic pseudocyst.

Pancreatic pseudocysts are generally treated by endoscopic cystogastrostomy. However, difficult cases involving abscess, necrosis, or risk of hemorrhage often require surgical intervention. Here, we report a case of a robotically assisted cystogastrostomy.

Single-incision sleeve gastrectomy for successful treatment of a gastrointestinal stromal tumor.

Background: Gastrointestinal stromal tumors (GISTs) are rare mesenchymal tumors that are located specifically in the gastrointestinal tract, with up to 60% of occurrences in the stomach, 30% in the small intestine, and 10% in the esophagus, colon, and rectum. The annual incidence of GISTs is about 15 cases per million, which in the United States equals 5000 cases per year. In most cases, these tumors are asymptomatic and are found incidentally on computed tomography scan or by endoscopy.

Structural and functional insights into DNA-end processing by the archaeal HerA helicase-NurA nuclease complex.

Helicase-nuclease systems dedicated to DNA end resection in preparation for homologous recombination (HR) are present in all kingdoms of life. In thermophilic archaea, the HerA helicase and NurA nuclease cooperate with the highly conserved Mre11 and Rad50 proteins during HR-dependent DNA repair. Here we show that HerA and NurA must interact in a complex with specific subunit stoichiometry to process DNA ends efficiently.

Development and morphology of class II Kenyon cells in the mushroom bodies of the honey bee, Apis mellifera.

Class II Kenyon cells, defined by their early birthdate and unique dendritic arborizations, have been observed in the mushroom bodies of evolutionarily divergent insects. In the fruit fly Drosophila melanogaster, Class II (also called clawed) Kenyon cells are well known for their extensive reorganization that occurs during metamorphosis. The present account reports for the first time the occurrence of mushroom body reorganization during metamorphosis in holometabolous insect species outside of the Diptera.
