Testicular Torsion Appearance and Diagnosis on Computed Tomography of the Abdomen and Pelvis: Case Report.

Introduction: Testicular torsion, or the twisting of the spermatic cord compromising blood flow to the testis, is a urologic emergency with the potential to cause infertility in male patients. The diagnosis may be clinical or confirmed using imaging, with ultrasound being the modality of choice.

Case Report: We present a case of right lower quadrant pain with radiation to the groin and right scrotum in a young male.

Threatened Respiratory Compromise in the Setting of Isolated Angioedema.

Isolated angioedema of the uvula, or Quincke's disease, is a rare condition that can cause respiratory compromise. Although typically self-limiting, episodes of angioedema may require prompt therapy to prevent obstruction of the proximal airway. In this case report we review the appropriate steps for initial evaluation of patients with suspected angioedema, primary etiologies, and appropriate initial therapy.

Use of 3D Printed Models in Resident Education for the Classification of Acetabulum Fractures.

Objective: To determine if three-dimensional (3D) printed models can be used to improve acetabular fracture pattern recognition and be a valuable adjunct in orthopedic resident education.

Design: Fifteen randomized testing stations with each containing plain radiographs (XRs), two-dimensional computed tomography (CT) scans, or 3D model of an acetabular fracture.

Setting: Two orthopedic residency programs based at Level 1 trauma centers.

In vivo HSV-1 DNA transport studies using murine retinal ganglion cells.

The mammalian retina, brain, spinal cord, and peripheral ganglia are all heterogeneous tissues. Each is composed of neuronal and glial cell partners embedded in a connective tissue bed and supplied by vascular and immune cells. This complicated structure presents many challenges to neuroscientists and cell biologists, e.

Delivery of herpes simplex virus to retinal ganglion cell axon is dependent on viral protein Us9.

Purpose: How herpes simplex virus (HSV) is transported from the infected neuron cell body to the axon terminal is poorly understood. Several viral proteins are candidates for regulating the process, but the evidence is controversial. We compared the results of Us9 deletions in two HSV strains (F and NS) using a novel quantitative assay to test the hypothesis that the viral protein Us9 regulates the delivery of viral DNA to the distal axon of retinal ganglion cells in vivo.

Adenosine inhibition of lipopolysaccharide-induced interleukin-6 secretion by the osteoblastic cell line MG-63.

Adenosine is known to inhibit inflammatory responses in many cell systems via a family of purine receptors termed "P1." The P1 family consists of the adenosine receptors (ADORA) of subtypes A(1), A(2a), A(2b), and A(3). In order to assess whether adenosine has anti-inflammatory actions in osteoblastic cells, we investigated its effects on lipopolysaccharide (LPS)-induced interleukin 6 (IL-6) release in an in vitro inflammatory functional response model.
