Introduction: We investigated the effect of ginkgo biloba on germ cell apoptosis and also on expressions of endothelial (eNOS) and inducible (iNOS) nitric oxide synthases after testicular torsion.
Materials And Methods: Thirty-two Wistar albino rats were randomly assigned into four groups. Torsion/detorsion (T/D) was performed on the rats in group 1, group 2 received ginkgo biloba for a month before T/D, group 3 received only gingko biloba for a month, and group 4 was the sham group. Left testicular torsion was created in group 1 and group 2, and the testes were untwisted and replaced in the scrotum for reperfusion. No procedure was applied to group 3, and after 1 month, testes were removed in all groups.
Results: Mean apoptotic cell, eNOS, and iNOS were increased in group 1. Group 2 showed significantly decreased apoptotic cells, eNOS, and iNOS in testes compared to group 1 (P < 0.05). The rats in group 3 had significantly decreased apoptotic cell, eNOS, and iNOS values, like the sham group (P < 0.05), and this group provided basal values.
Conclusions: Ginkgo biloba, as a free radical scavenger, seems to have a protective role against apoptosis in testicular ischemia reperfusion injury.

Phytotoxic air pollutants such as atmospheric nitrogen dioxide (NO) are among the major stresses affecting tree photosynthesis in urban areas. We clarified the relationship between NO concentrations and photosynthetic function for three major urban trees, Prunus × yedoensis, Rhododendron pulchrum, and Ginkgo biloba, planted in Kyoto and surrounding cities, combining our published data and new data collected from 2020 to 2023. High NO increased long-term water use efficiency for all species.

Given the multifactorial nature of AD, therapeutic strategies need to focus on disease-specific biochemical pathways. Given the significance of metabolic pathways in cognitive impairment, it is essential to investigate alternative disease modifiers capable of targeting multiple metabolic pathways, such as phytochemicals.

Background: Ginkgo biloba leaf extract EGb 761® has shown clinical efficacy in patients with mild cognitive impairment and dementia. However, the pharmacological action of EGb 761® in Alzheimer's disease (AD) remains unclear and molecular mechanisms targeted in the brain are not completely understood.
Hypothesis/purpose: We aimed to investigate 1) the potential sex-dependent effects of oral administration of EGb 761® in 5xFAD mice, an AD mouse model, and 2) the underlying microglial subtype responsible for the observed anti-inflammatory effects in the brain.

Vascular dementia (VD) is a neurocognitive disorder resulting from cerebral vascular disorders, leading to the demise of neurons and cognitive deficits, posing significant health concerns globally. Derived from Ginkgo biloba leaves, EGb761 is a potent bioactive compound widely recognized for its benefits in treating cerebrovascular diseases. Previous studies have demonstrated that the administration of EGb761 to VD rats enhances the proliferation, differentiation, and migration of neurons, effectively alleviating cognitive dysfunction.

-methyladenosine (mA) is a widespread post-transcriptional modification of RNA in eukaryotes. The conserved YTH-domain-containing RNA binding protein has been widely reported to serve as a typical mA reader in various species. However, no studies have reported the mA readers in ().
