Potential applications of reproductive and molecular genetic technologies in the selective breeding of aquaculture species [PDF]

open access: yes
The use of reproductive and genetic technologies can increase the efficiency of selective breeding programs for aquaculture species. Four technologies are considered, namely: marker-assisted selection, DNA fingerprinting, in-vitro fertilization, and ...

DNA fragmentation index (DFI) as a measure of sperm quality and fertility in mice. [PDF]

open access: yes, 2020
Although thousands of genetically modified mouse strains have been cryopreserved by sperm freezing, the likelihood of cryorecovery success cannot be accurately predicted using conventional sperm parameters.

Determination of ADP/ATP translocase isoform ratios in malignancy and cellular senescence

open access: yesMolecular Oncology, EarlyView.
The individual functions of three isoforms exchanging ADP and ATP (ADP/ATP translocases; ANTs) on the mitochondrial membrane remain unclear. We developed a method for quantitatively differentiating highly similar human ANT1, ANT2, and ANT3 using parallel reaction monitoring. This method allowed us to assess changes in translocase levels during cellular

High spatially sensitive quantitative phase imaging assisted with deep neural network for classification of human spermatozoa under stressed condition [PDF]

open access: yesarXiv, 2020
Sperm cell motility and morphology observed under the bright field microscopy are the only criteria for selecting particular sperm cell during Intracytoplasmic Sperm Injection (ICSI) procedure of Assisted Reproductive Technology (ART). Several factors such as, oxidative stress, cryopreservation, heat, smoking and alcohol consumption, are negatively ...

Assisted conception and Embryo Research with reference to the tenets of Catholic Christianity [PDF]

open access: yes, 2017
Religion has a considerable influence over the public’s attitudes towards science and technologies. The objective of the paper is to understand the ethical and religious problems concerning the use of embryo for research in assisting conception for ...

To Be or not to Be? A Critical Appraisal of the Welfare of Children Conceived through New Reproductive Technologies [PDF]

open access: yes, 2008
Over three million children are believed to have been born worldwide - and over 200,000 annually - as a result of “new reproductive technologies” (NRTs).

Early metastasis is characterized by Gr1+ cell dysregulation and is inhibited by immunomodulatory nanoparticles

open access: yesMolecular Oncology, EarlyView.
Breast cancer metastasis is associated with myeloid cell dysregulation and the lung‐specific accumulation of tumor‐supportive Gr1+ cells. Gr1+ cells support metastasis, in part, through a CHI3L1‐mediated mechanism, which can be targeted and inhibited with cargo‐free, polymeric nanoparticles.

Digital Modeling of Massage Techniques and Reproduction by Robotic Arms [PDF]

open access: yesarXiv
This paper explores the digital modeling and robotic reproduction of traditional Chinese medicine (TCM) massage techniques. We adopt an adaptive admittance control algorithm to optimize force and position control, ensuring safety and comfort. The paper analyzes key TCM techniques from kinematic and dynamic perspectives, and designs robotic systems to ...

Global stability of epidemic models with imperfect vaccination and quarantine on scale-free networks [PDF]

open access: yesarXiv, 2018
Public health services are constantly searching for new ways to reduce the spread of infectious diseases, such as public vaccination of asymptomatic individuals, quarantine (isolation) and treatment of symptomatic individuals. Epidemic models have a long history of assisting in public health planning and policy making.

Ficoll-400 density gradient method as an effective sperm preparation technique for assisted reproductive techniques

open access: yesJournal of Human Reproductive Sciences, 2016
BACKGROUND: Infertility being a burning issue, the male itself contributes about 40% as a cause, as evident by statistical data. However, Assisted Reproductive Technology (ART) has emerged as a powerful tool in the management of infertility.
