Recent trends and impact of localized surface plasmon resonance (LSPR) and surface-enhanced Raman spectroscopy (SERS) in modern analysis.

An optical biosensor is a specialized analytical device that utilizes the principles of optics and light in bimolecular processes. Localized surface plasmon resonance (LSPR) is a phenomenon in the realm of nanophotonics that occurs when metallic nanoparticles (NPs) or nanostructures interact with incident light. Conversely, surface-enhanced Raman spectroscopy (SERS) is an influential analytical technique based on Raman scattering, wherein it amplifies the Raman signals of molecules when they are situated near specific and specially designed nanostructures.

Current Use of Physiologically Based Pharmacokinetic modeling in New Medicinal Product Approvals at EMA.

Physiologically Based Pharmacokinetic (PBPK) Models are routinely used in drug development and therefore appear frequently in marketing authorization applications (MAAs) to the European Medicines Agency (EMA). For a model to be a key source of evidence for a regulatory decision, it must be considered qualified for the intended use. Advice on the data expected to allow qualification of a PBPK model or platform is provided in the EMA Guideline on the reporting of PBPK modeling and simulation.

A Rare Case of Primary Chondrosarcoma of the Breast: A Case Report and Comprehensive Literature Review.

Breast sarcomas are a diverse group of malignant neoplasms originating from the mammary stroma. They are uncommon tumors, often occurring as a component of other tumors. Among malignant breast mesenchymal tumors, pure sarcomas lacking epithelial components are even rarer, comprising only 0.

ROHHAD NET in Retrospect: Key Lessons Learned from Five Cases.

Objectives: To present cases of rapid onset obesity with hypothalamic dysfunction, hypoventilation, and autonomic dysregulation (ROHHAD) and discuss management insights.

Methods: Case records of patients fulfilling the criteria for ROHHAD and presenting to the Pediatric Endocrinology Division of All India Institute of Medical Sciences, New Delhi, between July 2019 and June 2024 were reviewed for clinical features, treatments, and outcomes.

Results: Five patients (4 boys, 1 girl) presented at a median age of 4 y (range 3.

Actinomycetes: A Source of Anticancer Metabolites.

Microbes in general, actinomycetes in particular, produce a wide range of antibiotics with various biological activities such as anticancer, antimicrobial, anti-inflammatory, antituberculosis and enzyme inhibition. Actinomycetes are filamentous gram-positive bacteria found in both terrestrial and marine environments. Currently, antibiotics such as Rifamycin, Tetracycline, Kanamycin, Neomycin, Streptomycin and Clavulanic acid derived from actinobacteria are highly useful in the medical field.
