A Rare Case of Penile Metastases as a Harbinger of Primary Pulmonary Adenosquamous Carcinoma.

Although lung cancer has a high propensity for distant metastatic disease, penile metastases from primary lung neoplasms are considered particularly rare. A 71-year-old male presented to our hospital with a rapidly enlarging hard palpable penile mass. MR imaging demonstrated two penile masses centered in the left and right corpus cavernosa.

Transport of heterologous proteins to the periplasmic space of Pseudomonas fluorescens using a variety of native signal sequences.

Bacterial expression of recombinant proteins containing disulfide bonds is facilitated by transport of the proteins to the periplasmic space. Several Pseudomonas fluorescens signal sequences have been identified that efficiently direct proteins to the periplasm and provide solubility and yield advantages over the production of proteins fused to the PelB signal sequence in E. coli.

The use of a pneumatic leg brace in soldiers with tibial stress fractures--a randomized clinical trial.

Study Design: Single blind randomized controlled replication study.

Objectives: Evaluate the effect of a pneumatic leg brace on return-to-activity and pain in soldiers with tibial stress fractures.

Methods And Measures: Thirty-one subjects diagnosed with tibial stress fractures were randomly assigned to either a brace or control group.
