A case of cytomegalovirus colitis initially misdiagnosed as colonic ischemia in an immunocompetent Japanese woman.

Cytomegalovirus colitis should be considered in a patient presenting with bloody stool even among immunocompetent patients.

Idiopathic Lymphocytic Pleuritis Responding to Corticosteroid Therapy.

An 83-year-old man presented with chronic dyspnea, and chest X-ray showed bilateral pleural effusion. Right thoracentesis revealed lymphocyte-predominant exudate with no malignancy; bacterial and mycobacterial cultures were negative. Thoracoscopy via the right chest and a biopsy of the same site were performed; these showed lymphoplasmacytic infiltration and fibrosis, ruling out malignancy or tuberculosis.

Bladder cancer invasion along a tension-free vaginal mesh.

Introduction: The effect of synthetic mesh after pelvic organ prolapse surgery on the progression of bladder cancer remains unclear.

Case Presentation: A 79-year-old woman who underwent a tension-free vaginal mesh procedure 8 years prior was diagnosed with carcinoma of the bladder. Although intravesical Bacillus Calmette-Guérin therapy was started, the tumor rapidly became muscle invasive.

Fluid dynamics alter body length via TGF-β/DBL-1 neuromuscular signaling.

Skeletal muscle wasting is a major obstacle for long-term space exploration. Similar to astronauts, the nematode displays negative muscular and physical effects when in microgravity in space. It remains unclear what signaling molecules and behavior(s) cause these negative alterations.

Microgravity elicits reproducible alterations in cytoskeletal and metabolic gene and protein expression in space-flown .

Although muscle atrophy is a serious problem during spaceflight, little is known about the sequence of molecular events leading to atrophy in response to microgravity. We carried out a spaceflight experiment using onboard the Japanese Experiment Module of the International Space Station. Worms were synchronously cultured in liquid media with bacterial food for 4 days under microgravity or on a 1-G centrifuge.
