Reasons for retraction of clinical research articles in PubMed indexed medical journals from 2012 to 2022.
Indian J Med Ethics
January 2025
Department of Clinical Pharmacology, Toipwala National Medical College and BYL Nair Charitable Hospital, Mumbai 400008, Maharashtra, INDIA.
Background: Misconduct in the publication of research articles is a serious concern for the scientific community. This study was conducted with the objective to assess various reasons for retraction of clinical research articles published in PubMed indexed journals from all over the world since 2012 to 2022.
Methods: A search was performed on the PubMed database for retracted research articles using filters for "retracted publication".
Developing Chemical Signatures for Categories of Household Consumer Products Using Suspect Screening Analysis.
Environ Sci Technol
January 2025
Center for Computational Toxicology and Exposure, Office of Research and Development, U.S. Environmental Protection Agency, Research Triangle Park, North Carolina 27711, United States.
Consumer products are a major source of chemicals that may pose a health risk. It is important to understand what chemicals are in these products to evaluate risk and assess new products for uncommon ingredients. Suspect screening analysis (SSA) using two-dimensional gas chromatography-high-resolution-time-of-flight/mass spectrometry (GCxGC-HR-TOF/MS) was applied to 92 consumer products from 5 categories.

BMC Oral Health
January 2025
Department of Conservative Dentistry, Faculty of Dentistry, Alexandria University, Alexandria, Egypt.
Background: Conservative dentistry introduced modern restoration designs, contributing to the greater use of partial-coverage ceramic restorations. New strong bondable ceramic materials made fabricating partial coverage ceramic restorations easier to restore the badly destructed teeth.
Aim Of The Study: This study investigated the impact of three distinct overlay preparation designs on the marginal fit (both before and after thermal aging) and the fracture resistance of overlay restorations fabricated using advanced zirconia-reinforced lithium disilicate (ALD) CAD/CAM glass-ceramic blocks.
Applications and prospects of indirect 3D printing technology in bone tissue engineering.
Biomater Sci
December 2024
Sichuan University, Chengdu, Sichuan, China.
In bone tissue engineering, manufacturing bone tissue constructs that closely replicate physiological features for regenerative repair remains a significant challenge. In recent years, the advent of indirect 3D printing technology has overcome the stringent material demands, confined resolution, and structural control challenges inherent to direct 3D printing. By utilizing sacrificial templates, the natural structures and physiological functions of bone tissues can be precisely duplicated.

Lecturer, Department of Oral and Maxillofacial Prosthodontics, Faculty of Dentistry, Ain Shams University, Cairo, Egypt.
Statement Of Problem: Duplicating complete dentures and achieving accurately fitting prostheses poses a challenge. Conventional methods are often time-consuming and susceptible to human error. Advancements in digital technology for denture fabrication offer a promising alternative to conventional duplication techniques, but studies comparing the methods are lacking.
