Despite newly developed antiepileptic drugs to suppress epileptic symptoms, approximately one third of patients remain drug refractory. Consequently, there is an urgent need to develop more effective therapeutic approaches to treat epilepsy. A great deal of evidence suggests that endogenous nucleosides, such as adenosine (Ado), guanosine (Guo), inosine (Ino) and uridine (Urd), participate in the regulation of pathomechanisms of epilepsy. Adenosine and its analogues, together with non-adenosine (non-Ado) nucleosides (e.g., Guo, Ino and Urd), have shown antiseizure activity. Adenosine kinase (ADK) inhibitors, Ado uptake inhibitors and Ado-releasing implants also have beneficial effects on epileptic seizures. These results suggest that nucleosides and their analogues, in addition to other modulators of the nucleoside system, could provide a new opportunity for the treatment of different types of epilepsies. Therefore, the aim of this review article is to summarize our present knowledge about the nucleoside system as a promising target in the treatment of epilepsy.

Since the building blocks of DNA are nonfluorescent, various external fluorescence reporters have been employed to investigate the structure, dynamics, and function of DNA G-quadruplexes (GQs) and i-motifs (iMs), which play an important role in gene regulation and expression. However, most of those fluorescence reporters lack the ability to provide site-specific structural information of interest. Therefore, it is necessary to develop fluorescent nucleoside analogues that can be covalently inserted into oligonucleotides, which not only serve this purpose, but minimize any potential perturbation towards the native structure of the DNA systems in question.

Triple‑negative breast cancer (TNBC), a highly malignant breast cancer subtype with a pronounced metastatic propensity, forms the focus of the present investigation. MDA‑MB‑231, a prevalently utilized TNBC cell line in cancer research, was employed. In accordance with the tumour angiogenesis theory, cancer cells are capable of instigating angiogenesis and the formation of a novel vascular system within the tumour microenvironment, which subsequently sustains malignant proliferation and metastasis.

Cordycepin, known for its tumor-suppressive and antiviral properties, has garnered attention due to its therapeutic and biological potential. Current Cordyceps militaris - based cordycepin production methods involve time-consuming and cost-intensive solid-state fermentation. Using an internet of things (IoT) architecture, we developed an active air-feed regulation fermentation system (AAFRFS) to detect CO2 emitted during C.

Background: Olutasidenib is a potent, selective, oral, small molecule inhibitor of mutant IDH1 (mIDH1) which induced durable remissions in high-risk, relapsed/refractory (R/R) mIDH1 AML patients in a phase 1/2 trial. We present a pooled analysis from multiple cohorts of the phase 1/2 trial of patients with R/R AML who received combination olutasidenib and azacitidine therapy.
Methods: Adult patients with mIDH1 AML received 150 mg olutasidenib twice daily plus standard-of-care azacitidine (OLU + AZA) and were evaluated for response and safety.

Malaria, a life-threatening disease caused by Plasmodium parasites, continues to pose a significant global health threat, with nearly 250 million infections and over 600 000 deaths reported annually by the WHO. Fighting malaria is particularly challenging partly due to the complex life cycle of the parasite. However, technological breakthroughs such as the development of the nucleoside-modified mRNA lipid nanoparticle (mRNA-LNP) vaccine platform, along with the discovery of novel conserved Plasmodium antigens such as the E140 protein, present new opportunities in malaria prevention.
