Latent fingerprints (LFPs) are invisible impressions that need to be developed before being used for criminal investigation; however, existing fingerprint visualization techniques face challenges, such as complex preparation and poor contrast. To advance practical fingerprint detection, green-emissive micron-sized curcumin/kaolin composites were synthesized a facile and cost-effective one-step physical cross-linking method, which exhibited unprecedented performance in developing diversified marks, including LFPs, knuckle prints, palm prints, and footprints, with clear three-level details on various substrates. Notably, the powders successfully developed LFPs that were aged for 30 days and even up to 100 days, meeting the stringent requirements for comprehensive forensic application.

BMJ Ment Health
November 2024
Institute of Health Data Analytics & Statistics, College of Public Health, National Taiwan University, Taipei, Taiwan.
Article Synopsis
- The study researched the optimal dose of lurasidone for treating bipolar depression, focusing on efficacy, acceptability, and metabolic/endocrine effects.
- It reviewed five clinical trials involving 2,032 patients and found that doses between 40-60 mg significantly improved depression, anxiety, and quality of life while experiencing manageable side effects.
- Results indicated that while higher doses led to increased side effects and weight gain, a 40-60 mg dose was generally the best choice for treatment without major risks of dropout or manic switch.
Comparison of conventional and digital impression approaches for edentulous maxilla: clinical study.
BMC Oral Health
November 2024
Department of Prosthodontics, Faculty of Dentistry, Hacettepe University, Ankara, Turkey.
Article Synopsis
- The study examines new methods for creating tissue-supported complete dentures (TSCDs), highlighting a shift towards faster, comfort-focused, and cost-effective digital and simplified impression techniques, particularly using intraoral scanners (IOS).
- It involved 15 patients with maxillary complete edentulism and compared various impression methods, including digital options with artificial intelligence support and traditional methods using zinc oxide eugenol and irreversible hydrocolloid.
- Results indicated digitally captured impressions are comparably effective to conventional methods, particularly in palatal areas, suggesting digital methods could be more widely adopted in clinical practice for improved denture fitting.
Principle of TEM alignment using convolutional neural networks: Case study on condenser aperture alignment.
Ultramicroscopy
December 2024
CEMES-CNRS, 29 rue Jeanne Marvig, Toulouse, 31055, France.
The possibility of automatically aligning the transmission electron microscope (TEM) is explored using an approach based on artificial intelligence (AI). After presenting the general concept, we test the method on the first step of the alignment process which involves centering the condenser aperture. We propose using a convolutional neural network (CNN) that learns to predict the x and y-shifts needed to realign the aperture in one step.

Int J Gynaecol Obstet
December 2024
Department of Obstetrics and Gynecology, Cairo University, Cairo, Egypt.
Objective: To evaluate the utility of low-cost simulation models to teach surgical techniques for placenta accreta spectrum (PAS), included in a multimodal education workshop for PAS.
Methods: This was an observational, survey-based study. Participants were surveyed before and after the use of low-fidelity mannequins to simulate two surgical techniques for PAS (one-step conservative surgery [OSCS] and modified subtotal hysterectomy [MSTH]), within a multimodal educational workshop.
