Subzonal insemination for the alleviation of infertility
Fertility and Sterility, 1990Methods were developed to facilitate the use of subzonal insemination to achieve fertilization in vitro. A clinical trial was undertaken in those patients having previously failed to achieve fertilization by in vitro fertilization, and in those presenting with severe oligospermia/oligoasthenospermia. From 85 patients, 585 oocytes were obtained.

Subzonal fertilization of mouse round spermatids
Science in China Series C: Life Sciences, 1997Mouse round spermatids were electrofused with homologous mature oocytes to examine the behaviour of their nuclei within the ooplasm and the abilities of development. A single spermatid was injected in the perivitelline space of a mature oocyte and an electron fusion pulse was given.

Electronic spectra of crystals with a subzone resummation technique
Physical Review B, 1990A very accurate method is presented for the continued-fraction expansion of the electron Green's-function propagator in crystals. The novelty consists in implementing the recursion technique in decoupled subzones of the first Brillouin zone, rather than in the whole Brillouin zone or in real space.

METHOD FOR ESTABLISHING THE SEVENTH SUBZONE OF THE AERODROME AREA
Akustika, 2021The existing regulatory and methodical base does not provide for establishing airport zones (AZs). There are no unified approaches to establishing relevant boundaries, control over them, and substantiating limitations on use of land spots. The developed procedure for establishing the sanitary (seventh) subzone in an AZ creates a universal algorithm for

Widening Twin Deficits in the Subzones
2021The two CFA subregions have experienced current account and fiscal deficits in recent years, mostly linked to adverse terms-of-trade shocks. These have been amplified in the wake of the pandemic.

Subzonal sperm insertion and the frequency of gamete fusion
Journal of Assisted Reproduction and Genetics, 1992The subzonal sperm insertion technique was applied to assess the potential of motile human spermatozoa to form pronuclei. In 184 mature human oocytes, subzonal sperm insertion was used as the primary mode of insemination in cases with abnormal semen analyses.

“Subzone-Counting” Method in Asian Facial Liposuction: A Retrospective Study
Journal of Craniofacial Surgery, 2023Background: Facial liposuction is a popular and reliable procedure for patients with subcutaneous fat accumulation pursuing the ideal face shape. However, complications like irregularities and asymmetry are still problems for plastic surgeons. To lower the incidence of the above complications, we developed the “subzone-counting”

Assisted fertilization by subzonal insemination and intracytoplasmic sperm injection
Reproduction, Fertility and Development, 1994The results of 600 consecutive treatment cycles of subzonal insemination (SUZI) and intracytoplasmic sperm injection (ICSI) are described in couples with failed fertilization after standard IVF or insufficient spermatozoa in the ejaculate for IVF.

Biological factors affecting subzonal sperm microinjection results
Reproduction, Fertility and Development, 1994One hundred and sixteen couples with severe male factor infertility underwent 139 subzonal sperm microinjection cycles. In total, 1343 oocytes were microinjected, resulting in a fertilization rate of 24%, followed by a cleavage rate of 65%. In 26% of the zygotes, fertilization was delayed and embryos derived from these zygotes demonstrated a poor ...
