Comparative Proteomic Analysis of Young and Adult Bull (Bos taurus) Cryopreserved Semen
Animals, 2021 The age of the bull is widely accepted to influence the production of sperm, affecting the amount and quality of produced semen, which in turn impacts the results of cryopreservation.

Could Uranus and Neptune form by collisions of planetary embryos? [PDF]
, 2020 The origin of Uranus and Neptune remains a challenge for planet formation models. A potential explanation is that the planets formed from a population of a few planetary embryos with masses of a few Earth masses which formed beyond Saturn's orbit and migrated inwards. These embryos can collide and merge to form Uranus and Neptune.

Human Embryonic Stem Cell (hESC) and Human Embryo Research
Pediatrics, 2012 Human embryonic stem cell research has emerged as an important platform for the understanding and treatment of pediatric diseases. From its inception, however, it has raised ethical concerns based not on the use of stem cells themselves but on objections

CRISPR-induced exon skipping is dependent on premature termination codon mutations
Genome Biology, 2018 In previous studies, CRISPR/Cas9 was shown to induce unexpected exon skipping; however, the mechanism by which this phenomenon is triggered is controversial.

Long noncoding RNAs: new insights in modulating mammalian spermatogenesis
Journal of Animal Science and Biotechnology, 2020 Spermatogenesis is a complex differentiating developmental process in which undifferentiated spermatogonial germ cells differentiate into spermatocytes, spermatids, and finally, to mature spermatozoa.

Induced pluripotent stem cell: A headway in reprogramming with promising approach in regenerative biology [PDF]
Veterinary World, 2017 Since the embryonic stem cells have knocked the doorsteps, they have proved themselves in the field of science, research, and medicines, but the hovered restrictions confine their application in human welfare.

Hypothyroidism Affects Uterine Function via the Modulation of Prostaglandin Signaling
Animals, 2021 Thyroid hormones control the functions of almost all body systems. Reproductive dysfunctions, such as abnormal sexual development, infertility, or irregularities in the reproductive cycle, might be associated with thyroid disorders.

Reexamining a Geometric Theory of Biological Growth [PDF]
arXiv, 2021 A first principles approach to the theoretical description of the development of biological forms, from a fertilized egg to a functioning embryo, remains a central challenge to applied physics and theoretical biology. Rather than refer to principles of self-organization and non-equilibrium statistical mechanics to describe a developing embryo from its ...

Eccentricity excitation and merging of planetary embryos heated by pebble accretion [PDF]
A&A 606, A114 (2017), 2017 Context: Planetary embryos can continue to grow by pebble accretion until they become giant planet cores. Simultaneously, these embryos mutually interact and also migrate due to torques arising from the protoplanetary disk. Aims: Our aim is to investigate how pebble accretion alters the orbital evolution of embryos undergoing the Type-I migration. In
