Cell-specific cis-natural antisense transcripts (cis-NATs) in the sperm and the pollen vegetative cells of Arabidopsis thaliana [version 1; referees: 2 approved]

F1000Research, 2018
Background: cis-NATs (cis-natural antisense transcripts) are transcribed from opposite strands of adjacent genes and have been shown to regulate gene expression by generating small RNAs from the overlapping region.

An Efficient Approach for RNA Extraction from Boar Sperm and Seminal Plasma

Bio-Protocol, 2019
Despite transcriptional silencing in mature sperm and cytoplasmic expulsion of RNA during the final sperm maturation process, thousands of RNAs have been successfully identified in ejaculated sperm. Although most of RNAs’ function is still unknown, it is

Ongoing graft-versus-host disease is a risk factor for azoospermia after allogeneic hematopoietic stem cell transplantation: a survey of the Late Effects Working Party of the European Group for Blood and Marrow Transplantation

Haematologica, 2013
The aim of this study was to assess the degree of spermatogenesis defects in sperm analysis in long-term male survivors after allogeneic hematopoietic stem cell transplantation in order to identify the risk factors related to potential infertility after ...

Connecting Droplet Adhesion with Sperm Kinematics: A New Paradigm in Sperm Quality Monitoring

Advanced Materials Interfaces
Conventional microscopy‐driven sperm health monitoring systems suffer from high infrastructural costs and complex protocols. Here, a simple, economical sperm motility assessment system is proposed.

The Surface Proteome of Bovine Unsexed and Sexed Spermatozoa

Animals
Current sperm sexing methods are costly and largely restricted to cattle, while immunological techniques targeting sex-specific membrane proteins may offer more economical alternatives.

Hydrodynamic Clustering of Human Sperm in Viscoelastic Fluids

Scientific Reports, 2018
We have numerically investigated sperm clustering behaviours, modelling cells as superpositions of regularised flow singularities, coarse-grained from experimentally obtained digital microscopy of human sperm, both in watery medium and a highly viscous ...

Sperm induction of somatic cell-cell fusion as a novel functional test

eLife
The fusion of mammalian gametes requires the interaction between IZUMO1 on the sperm and JUNO on the oocyte. We have recently shown that ectopic expression of mouse IZUMO1 induces cell-cell fusion and that sperm can fuse to fibroblasts expressing JUNO ...

The Effects of Cell Phone Waves (900 MHz-GSM Band) on Sperm Parameters and Total Antioxidant Capacity in Rats [PDF]

International Journal of Fertility and Sterility, 2013
Background: There is tremendous concern regarding the possible adverse effects of cell phone microwaves. Contradictory results, however, have been reported for the effects of these waves on the body.
