Currently, cervical cancer (CC) is the fourth recorded widespread cancer among women globally. There are still many cases of metastatic or recurring disease discovered, despite the incidence and fatality rates declining due to screening identification and innovative treatment approaches. Palliative chemotherapy continues to be the standard of care for patients who are not contenders for curative therapies like surgery and radiotherapy.

Cancer immune therapies, particularly programmed cell death protein 1 (PD-1) blockade immunotherapy, falter in aged individuals due to compromised T-cell immunity. Spermidine, a biogenic polyamine that declines along with aging, shows promise in restoring antitumor immunity by enhancing mitochondrial fatty acid oxidation (FAO). Herein, we report a spermidine-based chemoproteomic probe (probe ) that enables profiling of spermidine-binding proteins and screening for small-molecule enhancers of mitochondrial FAO.

Introduction: Legg-Calve-Perthes disease (LCPD) is a disorder involving the hips in young children of preschool and school-going age groups, more common in 4-8 years. The insufficient blood supply to the femoral head is the main reason behind various etiologic theories. Multiple factors affect the natural progression of the disease.

Article Synopsis
  • A new type of one-dimensional coordination polymers (CPs) has been created using a simple one-pot synthesis method with specific chemicals, showing promise in various scientific applications.
  • These CPs have been extensively tested and found to be very stable against heat and water, while also being effective at sensing fluoride ions both visually and through specialized measurement techniques.
  • They demonstrate a high level of sensitivity to fluoride, outperforming traditional detection methods, and show minimal interference from other common ions, making them a strong candidate for monitoring fluoride levels in drinking water.

Men with prostate cancer are at increased risk of developing cognitive decline by the use of second-generation androgen signaling inhibitors. To date, reliable and sensitive biomarkers that could distinguish men at high risk of cognitive dysfunction under androgen deprivation therapy (ADT) have not been characterized. We used high-throughput transcriptional profiling utilizing human prostate cancer cell culture models mimicking ADT, biomarker selection using minimal common oncology data elements-cytoscape, and bioinformatic analyses employing Advaita® iPathwayGuide and DisGeNET for identification of disease-related gene associations.

Prostate cancer is a widespread malignancy among men, with a substantial global impact on morbidity and mortality. Despite advances in conventional therapies, the need for innovative and less toxic treatments remains a priority. Emerging evidence suggests that dietary plant metabolites possess epigenetic-modifying properties, making them attractive candidates for prostate cancer treatment.

Article Synopsis
  • Chemotherapy remains the primary treatment for many cancers, but its effectiveness is limited by drug resistance often linked to lysosomal functions in cells.
  • Lysosomes play a dual role by sequestering chemotherapeutic drugs, thus lowering their availability and enhancing resistance; they also contribute to cancer progression through enzymatic activity and triggering cell death.
  • The review discusses mechanisms of lysosomal drug sequestration and explores strategies to target lysosomes, aiming to reverse drug resistance and improve cancer treatment outcomes.

Scientists are constantly researching and launching potential chemotherapeutic agents as an irreplaceable weapon to fight the battle against cancer. Despite remarkable advancement over the past several decades to wipe out cancer through early diagnosis, proper prevention, and timely treatment, cancer is not ready to give up and leave the battleground. It continuously tries to find some other way to give a tough fight for its survival, either by escaping from the effect of chemotherapeutic drugs or utilising its own chemical messengers like cytokines to ensure resistance.

A significant advancement in the field of epigenetic drug discovery has been evidenced in recent years. Epigenetic alterations are hereditary, nevertheless reversible variations to DNA or histone adaptations that regulate gene function individualistically of the fundamental sequence. The design and synthesis of various drugs targeting epigenetic regulators open a new door for epigenetic-targeted therapies to parade worthwhile therapeutic potential for haematological and solid malignancies.

  • - The study investigates the role of oxidative stress and unknown phototoxicity mechanisms in age-related macular degeneration (AMD), focusing on inhibiting the harmful aggregation of a key fluorophore, A2E.
  • - Using a drug repurposing approach, researchers identified entacapone as an effective inhibitor of A2E fluorescence and aggregation, which helps protect retinal cells from blue light damage.
  • - Entacapone appears to redirect A2E into less harmful forms, showing that the aggregation of A2E contributes to its phototoxic effects, offering potential therapeutic insights for AMD treatment.

Chronic respiratory insufficiency can result from respiratory infections like pneumonia, which can permanently harm the lungs and respiratory system. A 21-year-old female patient arrived at our emergency medicine department (ED) complaining of acute lower-limb pain that worsened when she walked. She also reported feeling weak and having an acute, undiagnosed fever that was resolved by taking medicine two days after the day of admission.

We use covariance velocity map imaging of fragment ions from the strong field double ionization of formaldehyde in conjunction with trajectory surface hopping calculations to determine the ionization yields to different singlet and triplet states of the dication. The calculated kinetic energy release for trajectories initiated on different electronic states is compared with the experimental values based on momentum resolved covariance measurements. We determine the state resolved double ionization yields as a function of laser intensity and pulse duration down to 6 fs (two optical cycles).
