To study the potential involvement of inhibin A (inhA), inhibin B (inhB), activin A (actA) and follistatin (FS) in the recruitment of follicles into the preovulatory hierarchy, growing follicles (ranging from 1 mm to the largest designated F1) and the three most recent postovulatory follicles (POFs) were recovered from laying hens (n=11). With the exception of <4 mm follicles and POFs, follicle...

BACKGROUND Inhibins are dimeric glycoproteins, composed of an alpha-subunit (INH-α) and one of two possible beta-subunits (βA or βB), with substantial roles in human reproduction and in endocrine-responsive tumours. Aims of this study were to determine the serological measurement of inhibin A (α-βA) in breast cancer patients during chemotherapy. PATIENTS AND METHODS A series of 30 breast canc...

background and objective: histopathological evaluation of granulosa cell tumors (gct) of the ovary may be confused morphologically with a wide variety of the tumors. immunohistochemical staining for inhibin and calretinin can be used for better diagnosis. although it has been suggested that inhibin can be a sensitive marker for gct, it maybe had negative results in some cases.  in addition, cal...

Granulosa cell (GC) inhibin A and B production is regulated by FSH and gonadal factors. This gonadotrophin is released as a mixture of glycoforms, which induce different biological responses in vivo and in vitro. Our aim was to determine the effect of recombinant human FSH (rhFSH) glycosylation variants on inhibin A and B production by rat GCs. Preparative isoelectro focusing was used to isolat...

Magnetic data is useful in both hydrocarbon exploration and mining exploration. In hydrocarbon exploration, aeromagnetic data is an effective method for locating strike-slip faulting in magnetic basement. Also, high resolution surveys enhance delineation of both subtle basement features and intrasedimentary sources. In fact, magnetic methods has evolved from its sole use for mapping basement st...

OBJECTIVE To investigate the relationship between serum concentrations of inhibin A, inhibin B and estradiol (E(2)) and the number of developing follicles during the administration of exogenous follicle-stimulating hormone (FSH) in various regimens in normo-ovulatory volunteers and to evaluate if inhibins act as suitable markers for the number of developing follicles during ovarian stimulation....

We consider the possibility to gain information on the lepton mixing matrix element |Ue3| from an improved experimental limit on the effective neutrino mass governing neutrino-less double beta decay. We show that typically a lower limit on |Ue3| can be set. Furthermore, we give the values of the sum of neutrino masses and |Ue3| which are allowed and forbidden by an experimental upper limit on t...
