Human spermatozoa selected by percoll gradient or swim-up are equally capable of binding to the human zona pellucida and undergoing the acrosome reaction
(Oxford University Press, 1991)
Several techniques have been used for selecting motile spermatozoa including Percoll and albumin gradients, swim-up, and glass wool filtration. A high yield of motile spermatozoa as well as an enhancement of motility are ...
Morpho-functional study of human luteal cell subpopulations
(Oxford University Press, 1994)
It has been reported that the mammalian corpus luteum is composed mainly of two subpopulations of luteal cells (large and small) of different morphology and function. The aims of this study were first to characterize ...
Scientific ethics of human cloning Ética científica de la clonación humana
(2005)
True cloning is fission, budding or other types of asexual reproduction. In humans it occurs in monozygote twinning. This type of cloning is ethically and religiously good. Human cloning can be performed by twinning (TWClo) ...
Ultrastructure of a 4-cell human embryo developed in vivo
(Oxford University Press, 1989)
The infrastructure of a 4-cell human embryo undergoing development in vivo is described. The embryo recovered from the Fallopian tube 130 h after a single episode of intercourse and 70 h after the luteinizing hormone peak ...
Morphologic and immunohistochemical organization of the human habenular complex
(2011)
The habenular complex (HbCpx) is a phylogenetically conserved brain structure located in the epithalamus of vertebrates. Despite its fundamental role in decision-making processes and the proposed link between habenular ...

Why should human-animal interactions be included in research of working equids’ welfare?
(MDPI AG, 2019)
The livelihood of working horses’ owners and their families is intimately linked to the welfare of their equids. A proper understanding of human-animal interactions, as well as the main factors that modulate them, is ...
On the ontogenetic origin of human beings. The scientific solution Sobre el origen ontogenético del ser humano. La solución científica
(2007)
Every living being is the result of a genome-environment interaction. Neither human oocytes nor spermatozoids have human functional genomes, but the zygote that they constitute may have a human functional genome and other ...
Regulation of human luteal steroidogenesis in vitro by nitric oxide
(1998)
To evaluate the effect of nitric oxide (NO·) in human
corpus luteum (CL) function, we investigated the
expression and the presence of NO· synthase (NOS) in
the human CL and the action of NO· on the in vitro
luteal ...
