Effect of metabolic and antioxidant supplementation on sperm parameters in oligo-astheno-teratozoospermia, with and without varicocele: a double-blind placebo-controlled study [PDF]

open access: yes, 2018
Since sperm require high energy levels to perform their specialised function, it is vital that essential nutrients are available for spermatozoa when they develop, capacitate and acquire motility.

Effects of peptides derived from active sites of visfatin on wound healing

open access: yesScientific Reports
Severe wounds (e.g., burns) often result in irreversible scarring, leading to cosmetic and functional impairments as well as secondary complications such as reduced skin strength and itching.

Targeting the CMKLR1‐Mediated Signaling Rebalances Immunometabolism State in Middle‐Age Testicular Macrophages

open access: yesAdvanced Science, EarlyView.
In middle age, testicular CMKLR1⁺ macrophages exhibited a pro‐inflammatory immunometabolic profile, mediated by adipose signals associated with high BMI. However, inhibition of CMKLR1 signaling, either through Cmklr1 genetic ablation or treatment with a CMKLR1 antagonist peptide, can reverse this phenotype.

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.

Clinically relevant enhancement of human sperm motility using compounds with reported phosphodiesterase inhibitor activity [PDF]

open access: yes, 2014
STUDY QUESTION: Can we identify compound(s) with reported phosphodiesterase inhibitor (PDEI) activity that could be added to human spermatozoa in vitro to enhance their motility without compromising other sperm functions?

Meta‐GWAS of Pig Semen Quality Traits Reveals Conserved Genes Regulating Mammalian Fertility

open access: yesAdvanced Science, EarlyView.
This study incorporated 14 210 individuals to perform a GWAS meta‐analysis of six semen quality traits. The GWAS meta‐analysis identifies 234 GWAS loci associated with semen quality traits. The incorporation with a functional genomics resource explains potential genetic regulation of ∼40% GWAS signals underlying semen quality traits.

Mapping the Non‐Canonical Splicing Variants: Decrypting the Hidden Genetic Architecture of Idiopathic Male Infertility

open access: yesAdvanced Science, EarlyView.
This study highlights the significance of non‐canonical splicing variants in male infertility, a factor often overlooked during the analysis of high‐throughput sequencing data. Incorporating the non‐canonical splicing variants prioritization in the genetic analysis pipeline will increase the genetic diagnosis of patients with male infertility ...

The Effect of X-Rays on Cytological Traits of Tuta absoluta (Lepidoptera: Gelechiidae) [PDF]

open access: yes, 2016
The tomato leafminer, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) is one of the most important pests of tomato. With the purpose of developing environmentally friendly control tactics such as the inherited sterility (IS) technique against this ...
