A supernumerary ovary is an exceedingly rare disorder, in which the structure containing ovarian tissue is located at some distance from the normally placed ovary. 16 cases of endometriosis or tumors originating in a supernumerary ovary have been published in the English literature, but no case of coexisting endometriosis and a tumor has been published. We present the case of a 40-year-old female with cystic endometrioma with coexisting fibroma originating in a supernumerary ovary in the rectovaginal pouch.

- A recombinant rat aminopeptidase-B (Ap-B) was produced in E. coli as a GST fusion protein and purified through specific chromatography methods.
- Metal-substituted variants of Ap-B (Co(II)- and Cu(II)-Ap-B) were created, with Co(II)-Ap-B showing activity similar to the original enzyme, while Cu(II)-Ap-B demonstrated significantly lower activity.
- The study measured dissociation constants for zinc and cobalt in the enzymes and reported EPR parameters for Cu(II)-Ap-B, highlighting its distorted tetrahedral coordination geometry similar to other copper-enzyme complexes.
Structures and phase behavior of multilamellar vesicles of 1,2-dipalmitoyl-L-phosphatidylcholine (DPPC) containing various amount of ganglioside GM3 with a C18:1 sphingoid base and a 24:0 acyl chain (GM3(18,24)) were investigated by small-angle X-ray diffraction. Below 3.5 mol% GM3 content, the phase behavior was similar to that of pure DPPC except for a slight increase of lamellar repeat distance in the L(beta'), the P(beta') and the L(alpha) phases and a decrease of the pretransition temperature.

Serum levels of tumor necrosis factor-alpha and interleukin 6 were also elevated at presentation, and they returned to normal levels after chemotherapy. Although the total serum cholesterol level was below normal on admission, it increased after chemotherapy.

99mTc-galactosyl human serum albumin (99mTc-GSA) is a newly developed receptor-binding agent specific for the asialoglycoprotein receptor, which resides exclusively on the plasma membrane of mammalian hepatocytes. Liver scintigraphy using 99mTc-GSA was performed on 13 patients with liver disease. Dynamic data were obtained by gamma camera during 40 min after the intravenous injection of 3 mg (185 MBq) of 99mTc-GSA.
