“A new sesquiterpenoid (1), illudin T, was isolated from the culture of basidiomycete Agrocybe salicacola. The structure of the new compound was elucidated on the basis of spectral data.”
“Objective To determine if feline lacrimal glands, glands of the third eyelid, corneas, and corneal sequestra contain porphyrins, which could be responsible for the brown/amber discoloration of corneal sequestra and tears in affected cats.
Procedures Samples of grossly normal cornea, lacrimal gland,
gland of the third eyelid, and sequestra obtained via keratectomy were collected. Porphyrin selleck chemical concentrations of the homogenate
were determined by spectrofluorometry with protoporphyrin IX and coproporphyrin III dihydrochloride used as standards. A hamster harderian gland was used as a positive control.
Results Normal tissues were harvested from one eye each of 14 nonclient owned, adult, mixed-breed, short-hair cats euthanized for reasons not associated with this study. Eighteen sequestra were acquired from AG-120 price cats undergoing unilateral lamellar keratectomies. Breeds of the affected cats included eight Himalayan, five domestic shorthair, and one each of four other breeds. Only the positive control and standards contained levels of porphyrins above background. All feline samples examined were histologically normal with no evidence of porphyrins.
Conclusions Porphyrins are absent in normal feline lacrimal glands, corneas, and corneal sequestra. Porphyrins do not appear to be the cause of the brown/amber color of feline corneal sequestra.”
“A 63-year
old male with prior bioprosthetic mitral valve replacement and coronary artery bypass graft surgery presented with dyspnea. C-reactive protein and white AZD4547 blood cells were elevated and serial blood cultures were negative. Transesophageal echocardiography showed a paravalvular leak and a thickened anterior leaflet of unclear either infective or degenerative origin. For differential diagnosis, cardiac 128-dual source computed tomography (CT) was performed. The CT image showed a thickened anterior leaflet and further revealed that the paravalvular leak was draining into a large wall thickened pseudoaneurysm with dense tissue adjacent suggestive for an abscess. Therefore, (18)fluorodeoxyglucose-positron emission tomography ((18)FDG-PET) was appended and fused with the CT images. There was no tracer-uptake surrounding the leak excluding an abscess. However, an increased (18)FDG-tracer uptake at the thickened anterior leaflet indicated active inflammation. During the subsequent cardiac surgery, vegetations were identified on the anterior cusp of the bioprosthetic valve. Intraoperative biopsy was taken and the cell culture was positive for Staphylococcus aureus.
