Variations in Semen Quality and the Relationship of Semen Quality to Fertility in Turkeys ,
Poultry Science, 1968 Abstract INTRODUCTION IT would be of great value if males could be selected on the basis of semen quality prior to the breeding season. The thought of such a relationship is particularly intriguing in turkey management where considerable artificial insemination is practiced and where, in many instances, fertility levels are not satisfactory. Little

FEBS Letters, EarlyView.Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

FLUCTUATION OF SERUM AND SEMINAL INHIBIN IN RELATION TO BULL FERTILITY [PDF]
Veterinary Medical Journal - Giza, 1998 Blood and semen samples were collected for six successive months from 21 Friesian bulls. These bulls were used for natural service and were divided into three groups based on their semen characteristics. The first group consisted of bulls with high semen

Semen quality and intrauterine insemination
Reproductive BioMedicine Online, 2003 There is good evidence in literature that intrauterine insemination (IUI) is the best first line treatment and most cost-effective procedure for moderate male factor subfertility. It seems very difficult to identify individual semen parameters predicting the likelihood of pregnancy after IUI.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
FEBS Letters, EarlyView.Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Factors Affecting Fresh Semen Quality in Pasundan Cattle at UPTD BPPIBTSP Ciamis
Journal of Applied Veterinary Science and Technology, 2021 Background: Pasundan cattle are local cattle native to Indonesia. One way to conserve beef cattle genetics is to use Artificial Insemination technology. The success of Artificial Insemination can be influenced by the quality of semen.

FEBS Letters, EarlyView.We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

Diversity and complexity in neural organoids
FEBS Letters, EarlyView.Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

A new perspective on semen quality of aged male: The characteristics of metabolomics and proteomics
Frontiers in Endocrinology, 2023 BackgroundSemen quality is negatively correlated with male age and is mainly quantified by a routine semen analysis, which is descriptive and inconclusive.
