5. UpToDate

UpToDate is a popular clinical decision support website that summarises medical knowledge, clinical recommendations, pharmacological information, and more. Clinicians, healthcare workers, and medical students subscribe to it. UpToDate delivers evidence-based medical information on many topics. Research and medical advances are updated routinely. Users may get succinct summaries of essential information for various diseases or disorders by subject. Clinicians use UpToDate to keep current on medical research and make educated clinical decisions.

6. ClinicalTrials.gov

ClinicalTrials.gov is an online database of global clinical studies. It is a clinical trial registry that provides the trial’s purpose, participant eligibility, research design, results, and sponsor contact information.

ClinicalTrials.gov helps patients, doctors, and researchers. Patients can learn about ongoing clinical studies that may offer therapy. It helps doctors track studies and refer eligible individuals. The database might reveal ongoing research and prospective collaborations. ClinicalTrials.gov improves clinical research transparency, accessibility, and participation.

7. ScienceDirect

ScienceDirect is a major search engine commercial database of scientific and technical articles. It indexes approximately 10 million abstracts and full-text papers from medicine, biology, chemistry, physics, and engineering. ScienceDirect is a helpful resource for scholars seeking broad scientific literature coverage.

ScienceDirect requires institutional or individual subscriptions. Many academic and research organisations include ScienceDirect in their library subscriptions, allowing scholars to read the publications for free. ScienceDirect allows scholars to narrow their searches by author, keyword, publication date, and more.

TRIP Database curates and links high-quality, evidence-based information. It includes free clinical guidelines, systematic reviews, patient information booklets, and more from respected sources. TRIP provides credible medical information about medicine, health, and social care for researchers, doctors, and students.

TRIP Database prioritises free content. Curated links give high-quality content without a membership. TRIP’s search and UI help consumers locate relevant materials fast. It helps folks who need free, dependable medical resources.

9. PsycINFO

Psychology-related abstracts database PsycINFO is well-known. It indexes 2.7 million journal articles, books, book chapters, dissertations, and technical reports. PsycINFO includes clinical, social, cognitive, and other psychological issues.

PsycINFO provides comprehensive psychological research and mental health information to researchers. Its wide coverage, including historical documents from the 1800s, helps explain psychology science’s growth. PsycINFO’s powerful search features assist scholars find relevant articles in the enormous database.

Like ScienceDirect, PsycINFO requires a membership. PsycINFO requires institutional or individual subscriptions from academic or research institutions or other subscription services. PsycINFO’s vast psychological literature is free in some libraries.

10. Scopus

Researchers, physicians, and students can search Scopus for peer-reviewed material. Scopus includes medical, biology, chemistry, physics, engineering, social sciences, and humanities with over 70 million records, 50 million abstracts, and 20 million full-text articles.

Scopus’ wide scientific journal, book, and conference proceedings coverage is a major benefit. This breadth lets consumers study numerous sources and get insights from multiple fields. Scopus supports transdisciplinary research and cooperation by covering so many subjects.

Scopus’s characteristics promote research. Its extensive search features let users refine their queries and find particular information in the massive database. Document type, publication date, and author affiliation filters can reduce results. These technologies speed up literature searches for scholars.

Scopus facilitates researcher cooperation using its tools. Users may network, share research, and work together. These collaborative characteristics promote scientific advancement and innovation through networking, multidisciplinary cooperation, and idea sharing.

Conclusion

Medical research requires precise and current information. This article discusses the Top 10 Search Engines for Medical Research which include huge databases of peer-reviewed publications and specialised collections of systematic reviews and clinical trials. These search engines help researchers, clinicians, and students explore, discover, and advance medical knowledge, whether it’s PubMed’s extensive biomedical literature coverage, Cochrane Library’s evidence-based resources, or ScienceDirect’s diverse journal collection. These search engines help the medical community find fresh insights that drive innovation, enhance patient care, and define the future of healthcare.

Designed to monitor the freshness of seafood in real-time by responding to pH changes, the film offers a practical solution for improving food safety and reducing waste.

This film detects the release of volatile amines, compounds typically associated with spoilage, and indicates food quality through visible color changes, say sources from NIT Rourkela.

These natural components make the film biodegradable, safe, and responsive, aligning with sustainability goals and offering a non-invasive way to assess seafood freshness.

Findings

The findings of this research have been published in the journal Food Packaging and Shelf Life in a paper co-authored by Prof. Preetam Sarkar (as the lead corresponding author), along with his research scholars, Mr. Rahul Thakur, Miss Harshi Singhi, Mr. Vedsagar Rajesh Suryavanshi, and Dr. Ravichandran Santhosh.

Other co-authors in this work include Dr. Khalid Gul from NIT Rourkela, Dr. Swarup Roy from Lovely Professional University, Dr. Srinivas Janaswamy from South Dakota State University, Brookings, USA and Dr. Kirtiraj K. Gaikwad from IIT Roorkee.

Fishing

India is the world’s second-largest fish-producing nation, contributing approximately 8% of global fish production, say NIT Rourkela researchers.

It also holds the distinction of being the top five producer of shrimp globally, with frozen shrimp being the top export commodity.

Given the scale and importance of seafood production, innovations that ensure freshness and reduce spoilage are of immense value, say NIT Rourkela researchers.

In this context, intelligent packaging systems, which preserve food while monitoring its quality, are rapidly gaining global interest.

Unlike conventional packaging that serves merely as a protective barrier, the intelligent packaging film developed by NIT Rourkela team offers visual cues about the product’s condition, making it a promising solution for enhancing food safety and reducing waste.

The beetroot peel extract was prepared separately, and then combined with the starch, gum tragacanth, and a small amount of glycerol to cast the films.

These were dried and tested for their pH-sensitivity and effectiveness in monitoring seafood freshness, said Prof Preetam of NIT Rourkela.

Pigments

Beetroot peels contain betalains, a group of pigments known for their bright colours and pH sensitivity, say NIT Rourkela researchers.

These pigments also offer antioxidant and antimicrobial benefits, making them suitable for food-related applications.

Incorporating these natural compounds into the starch-based film creates a biodegradable, safe, and responsive packaging material.

When the seafood begins to spoil and pH levels rise, the film changes colour, providing a clear visual indicator of freshness.

Starch

The choice of Kodo millet starch and gum tragacanth contributes to the film’s biodegradable and eco-friendly profile.

Kodo millet is an underutilised grain with excellent film-forming properties, while gum tragacanth enhances the mechanical strength and flexibility of the material.

The researchers believe that using such agricultural by-products not only supports sustainability but also adds value to food processing waste, such as beetroot peels.

At the laboratory scale, the cost of producing the film was estimated approximately Rs. 900 per kilogram.

When scaled up for industrial production, the cost is projected to range between Rs. 400 and Rs. 600 per kilogram, making it a potentially viable option for commercial use.
