New RP-HPLC method for orlistat analysis validated

2025-08-21
(Press-News.org) A recent study published in Current Pharmaceutical Analysis introduces a robust and validated reverse-phase high-performance liquid chromatography (RP-HPLC) method for the analysis of orlistat, a widely used anti-obesity drug. The method, developed by researchers from KIET School of Pharmacy in India, ensures accurate quantification and is fully compliant with International Council for Harmonisation (ICH) guidelines.

The research team, led by Kandasamy Nagarajan, optimized the chromatographic conditions to achieve high sensitivity and precision. "Our method uses an XBridge C8 column and acetonitrile as the mobile phase, providing sharp peaks and minimal retention times," said Nagarajan. The method was validated for linearity, accuracy, precision, and robustness, with results showing excellent correlation and minimal variability.

The study also evaluated the method's robustness by introducing small variations in detection wavelength and flow rate, confirming its reliability for routine analysis. "This method is not only precise but also cost-effective, reducing solvent use and analysis time," said co-author Snigdha Bhardwaj. The validated method is suitable for quality control labs, ensuring accurate quantification of orlistat in formulations.

The research highlights the method's potential for broader applications in pharmaceutical analysis, emphasizing its alignment with sustainability goals by minimizing solvent use and reducing analysis time. Future work may focus on further validation for stability-indicating methods.

How AI will transform mental health support for patients with breast cancer

2025-08-21
From virtual counselors that can hear depression creeping into a person’s voice to smart watches that can detect stress, artificial intelligence is poised to revolutionize mental health care for patients with breast cancer. In a new paper, UVA Cancer Center’s J. Kim Penberthy, PhD, and colleagues detail the many ways artificial intelligence could help ensure patients receive the support they need. AI, they say, can identify patients at risk for mental-health struggles, get them treatment earlier, provide continuous psychological monitoring and even ...

Optimizing how cells self-organize

2025-08-21
Key Takeaways Harvard physicists have developed a computational method that can uncover the rules that cells use to self-organize, translating the complex process of cell growth into an optimization problem a computer can solve. The technique they use is automatic differentiation, originally built for training neural networks, but used in this context for predicting how small changes in genes or cellular signals affect the final design.   Scientists could someday use such predictive models in real biological experiments to design living tissues with specific functions or shapes. One of the most fundamental processes in all of biology ...

Impact of cancer on forensic DNA methylation age estimation

2025-08-21
“[…]age estimation on blood stains from cancer patients might not result in significantly higher estimation errors, except for very aggressive forms of cancer.” BUFFALO, NY — August 21, 2025 — A new research paper was published in Volume 17, Issue 7 of Aging (Aging-US) on July 17, 2025, titled “The influence of cancer on a forensic age estimation tool.” In this study by Charlotte Sutter, Daniel Helbling, Cordula Haas and Jacqueline Neubauer from the Zurich Institute of Forensic Medicine, University ...

Researchers use photonic origami to fold glass into microscopic 3D optical devices

2025-08-21
WASHINGTON — Researchers have developed a technique to fold glass sheets into microscopic 3D photonic structures directly on a chip — a process they call photonic origami. The method could enable tiny, yet complex optical devices for data processing sensing and experimental physics. “Existing 3D printers produce rough 3D structures that aren’t optically uniform and thus can’t be used for high-performance optics,” said research team leader Tal Carmon from Tel Aviv University in Israel. “Mimicking the way a pinecone’s scales bend outward to release ...

Dr. Matthew Greenblatt awarded Paul-Gallin Trailblazer Prize for bone stem cell discoveries

2025-08-21
Dr. Matthew Greenblatt will receive the prestigious Paul-Gallin Trailblazer Prize for Physician-Scientists in recognition of his discovery of distinct types of bone-building stem cells in different parts of the body. These unique cells have the ability to create copies of themselves as well as develop into specialized cells that perform distinct functions in the body. Each year, the Foundation for the National Institutes of Health awards the Paul-Gallin Trailblazer Prize to an early- to mid-career physician-scientist who is translating their basic science discoveries into new ways to diagnose, prevent, treat, or cure disease ...

Natural products used as disinfectants in prosthodontics and oral implantology

2025-08-21
Infection control is paramount in prosthodontics and oral implantology to prevent complications like denture stomatitis and peri-implantitis. While synthetic disinfectants (e.g., chlorhexidine) are widely used, their side effects—including mucosal irritation, toxicity, and antimicrobial resistance—drive the search for safer alternatives. Natural products derived from plants, animals, and minerals offer promising solutions due to their antimicrobial efficacy, biocompatibility, and environmental sustainability. Key Natural Agents and Mechanisms Plant-Based Products: Clove oil (eugenol), tea tree oil (terpinen-4-ol), neem (azadirachtin), ...

A multisensor approach to accurate snow water equivalent retrieval from space

2025-08-21
Snow water equivalent (SWE) measurements are critical for water resource management, yet existing remote sensing methods struggle to provide accurate, large-scale estimates. This study introduces a multisensor approach combining optical snow cover data and L-band interferometric synthetic aperture radar (InSAR) to enhance SWE retrievals. By analyzing multiple optical snow cover datasets in conjunction with UAVSAR L-band InSAR data, the researchers demonstrate how these combined technologies can effectively address the uncertainties in snow measurement, improving the accuracy of SWE change estimations over snow-covered regions. Current snow monitoring techniques, particularly those ...

Researchers find ways to improve liquid hydrogen tank efficiency

2025-08-21
PULLMAN, Wash. – Washington State University researchers have developed a mathematical model and a set of recommendations to improve liquid hydrogen storage tank operations that could someday make hydrogen a more viable alternative for powering vehicles and other industrial processes. The researchers used real-world tank data to identify operational regimes in which hydrogen boils off and is lost, which can be as much as 25% of the hydrogen delivered to storage tanks. The work is published in the journal Cryogenics. “If we want to reduce reliance on fossil fuels and come up with fuel that is clean and produced from renewable energy sources, then liquid hydrogen ...

New era in transthyretin amyloidosis: From stabilizers to gene editing

2025-08-21
Transthyretin amyloidosis (ATTR) is caused by the misfolding and aggregation of the transthyretin (TTR) protein, leading to multi-organ damage. Two main forms exist: hereditary ATTR (ATTRv), linked to TTR gene mutations, and wild-type ATTR (ATTRwt), associated with aging. Historically underdiagnosed, ATTR carried poor prognoses, particularly in advanced cardiac or neuropathic disease. However, the past decade has seen unprecedented therapeutic advances. Diagnostic Advances Enable Earlier Intervention Improved detection ...
