What's the difference between semeniferous and seminiferous?
Semeniferous
Definition:
(a.) Seminiferous.
Example Sentences:
(1) The impairment of cremaster reflex by bilateral dissection of the genitofemoral nerves resulted in a decrease of testicular weight and degenerative changes of the semeniferous tubules in the rats kept in a cold room (4 degrees C), but not in the rats kept at room temperature (22 degrees C).
(2) Lesions ranged from hypocellularity of the semeniferous tubules and relative hyperplasia or degeneration of interstitial cells to complete connective tissue replacement of the testicular parencyma.
(3) Visual observations of the testes at the time of slaughter, dry matter content of the testes, and histological examinations--all revealed normal growth and active spermatid formation from healthy germinal epithelia in all semeniferous tubules.
Seminiferous
Definition:
(a.) Seed-bearing; producing seed; pertaining to, or connected with, the formation of semen; as, seminiferous cells or vesicles.
Example Sentences:
(1) One hour after direct mechanical cardiomassage (DMCM) a moderately pronounced edema of the intercellular spaces in the basal compartment of the seminiferous epithelium, normal content of lactate and succinate dehydrogenases, and a certain decrease in the activity of glucose-6-phosphate dehydrogenases and NAD- and NADP-diaphorases were noted.
(2) Developing seminiferous tubules and interstitial cells were first seen on day 26, and were well established one day later.
(3) After 35 and 43 days, spermatogenesis was complete in 99.6% of the tubular cross sections, and most tubular cross sections were in stages IV-VII of the cycle of the seminiferous epithelium.
(4) In the following days, CK 8, CK 18 and CK 19 were detected in Sertoli cells in the differentiating seminiferous cords, but progressively the reactivity for CK 19 decreased and was no longer observed after 18.5-19.5 days of gestation.
(5) The ultrastructural study of nucleoli and ribonucleoprotein-containing structures in human seminiferous tubules revealed that the nucleoli of spermatogonia, spermatocytes and Sertoli cells exhibited a tripartite structure consisting of: a fibrillar center, a compact granular portion, and a reticular portion containing both pars fibrosa and pars granulosa.
(6) Degenerating seminiferous tubules and areas of cellular connective tissue are located underneath or within the tunica albuginea.
(7) The low mitotic index of type A0 spermatogonia (0.1%) indicated that these cells were not actively involved in the production of spermatogonia or spermatocytes during each cycle of the seminiferous epithelium and thus were considered as reserve stem cells.
(8) Testicular atrophy in myotonic dystrophy is caused by a primary and progressive atrophy of the seminiferous tubules.
(9) Seminiferous tubules from adult animals and germ cells at the meiotic and post-meiotic stage of differentiation possessed two enzyme forms that could be distinguished from those present in somatic cells of the seminiferous tubules: (a) a calcium-calmodulin-dependent form with high affinity for both cAMP and cGMP, similar to forms described in other tissues from different species, and (b) a calcium-calmodulin-independent phosphodiesterase with high affinity for cAMP and present only in post-meiotic cells, previously identified also in germ cells of the rat.
(10) UC increased the mean diameter of seminiferous tubules by 21% (p less than 0.01) and of their lumina by 51% (p less than 0.01), but did not significantly increase mean height of seminiferous epithelium or estimated length of seminiferous tubules per testis.
(11) There was also a proliferation of the germinal cells, and a number of mitotic figures were observable in the seminiferous tissue.
(12) Mitotic index was determined in whole mounts of segments of seminiferous tubules of (101 X C3Hf)F1 male mice at 3 hr intervals from 18.00 to 06.00 hours, and at hourly intervals from 08.00 to 16.00 hours.
(13) The activities of five glycosidases (beta-N-acetylhexosaminidase, alpha-L-fucosidase, beta-D-galactosidase, alpha-D-glucosidase and alpha-D-mannosidase) were also investigated in the seminiferous tubules and interstitial tissues.
(14) We show that AMH reproduces the caracteristical "freemartin effect"; namely the initial inhibition of gonadal and germ cell development, and the differentiation of fetal Sertoli cells forming seminiferous cord-like structures and producing immuno and bioactive AMH.
(15) Extensive necrossis and exfoliation of the seminiferous elements were conspicuous.
(16) Otherwise, seminiferous tubules were histologically normal at 15 days after induction of diabetes.
(17) In this way, inhibin may be an important regulator of the number of developing Sertoli cells and of the length of the seminiferous tubuli in the testis and of the number of developing follicles in the ovary.
(18) By day 34, only elongated spermatids remained in a few tubules and thereafter very little regeneration of the seminiferous epithelium occurred, except for one rat which showed a better regeneration.
(19) In this study at the light and transmission electron microscopy level, evidences are given that in T. (C.) tridentata, spermatogenesis is centrifugal and occurs around seminiferous tubules surrounding the lumen that is a blood vessel.
(20) The spatial extension of these megalospermatocyte populations is spherical to elliptical, some of them look like a section of a spiral around the longitudinal axis of the seminiferous tubule.
