Department of Pharmacy, Faculty of Chemical and Life Sciences, Abdul Wali Khan University Mardan, Mardan, 23200, Pakistan.

Alkaloids, a diverse class of naturally occurring compounds, have shown significant potential in the treatment of leukemia by targeting key molecular pathways and cellular mechanisms. This review discusses several potent alkaloids, such as homoharringtonine, chaetominine, matrine, and jerantinine B, which induce apoptosis, cell cycle arrest, and autophagy and inhibit signaling pathways including PI3K/Akt/mTOR, MAPK, and NF-κB. For instance, homoharringtonine induces apoptosis in acute myeloid leukemia (AML) cells via the SP1/TET1/5hmC/FLT3/MYC axis, while chaetominine enhances chemosensitivity by inhibiting the PI3K/Akt/Nrf2 pathway.

Chemotherapy is a key treatment option for gastric cancer, but over 50% of patients develop either inherent or acquired resistance to these drugs, resulting in a 5-year survival rate of only about 20%. The primary treatment for advanced gastric cancer typically involves chemotherapy based on platinum or fluorouracil. Several factors can contribute to platinum resistance, including decreased drug uptake, increased drug efflux or metabolism, enhanced DNA repair, activation of pro-survival pathways, and inhibition of pro-apoptotic pathways.

Cervical cancer begins in the cells lining the cervix and is caused by persistent infection with certain types of human papillomavirus (HPV). Initially, it has no symptoms, and later it causes pelvic pain, abnormal vaginal bleeding, and pain during intercourse. It is the fourth-ranked cancer among women, and many women die from cervical cancer every year, particularly in low-income countries and the majority could be prevented with early detection and treatment.

Background: The Choroid Plexus (ChP) plays a vital role in brain homeostasis, serving as part of the Blood-Cerebrospinal Fluid Barrier, contributing to brain clearance pathways and being the main source of cerebrospinal fluid. Since the involvement of ChP in neurological and psychiatric disorders is not entirely established and currently under investigation, accurate and reproducible segmentation of this brain structure on large cohorts remains challenging. This paper presents ASCHOPLEX, a deep-learning tool for the automated segmentation of human ChP from structural MRI data that integrates existing software architectures like 3D UNet, UNETR, and DynUNet to deliver accurate ChP volume estimates.
