Article Synopsis
- Advanced ultrasound techniques offer better insights into non-melanoma skin cancers compared to traditional methods like dermoscopy, enhancing assessment of tumor margins and morphology.
- In a study of 11 skin tumors (mostly basal and squamous cell carcinomas) from patients aged 66 to 98, ultrasound effectively measured tumor depth and correlated well with histological findings.
- The ultrasound showed that all tumors were solid and stiff, with high levels of neovascularity, indicating its potential as a quick and useful pre-operative tool.
Nanoparticles have found applications across diverse sectors, including agriculture, food, cosmetics, chemicals, mechanical engineering, automotive, and oil and gas industries. In the medical field, nanoparticles have garnered considerable attention due to their great surface area, high solubility, rapid dissolution, and enhanced bioavailability. Nanopharmaceuticals are specifically designed to precisely deliver drug substances to targeted tissues and cells, aiming to optimize therapeutic efficacy while minimizing potential adverse effects.

- Dengue remains a significant public health issue in Malaysia, with over 600,000 cases and 1,200 deaths recorded from 2015 to 2021, marking a 100% increase from the previous seven years.
- Recent studies on the molecular epidemiology of dengue in the country are scarce, prompting this analysis of 4,004 complete envelope gene sequences from all four dengue virus serotypes collected during the same period.
- The research found that the dengue virus populations in Malaysia are highly diverse, with ongoing turnover of genotypes, and indicated that Selangor and Johor are key areas for the emergence and spread of dengue, linked to extensive networks throughout South and East Asia.
With the increasing use of pressure-sensitive adhesives (PSAs) in various industries, there is a need for greater sustainability, particularly in developing polymer materials from renewable resources, as well as the reuse and recycling of materials to reduce environmental impact, reduce waste, or extend their life. Here, we outlined the required properties of PSAs which are governed by the molecular parameters (molecular weights, dispersities, molecular weight between entanglement, molecular weight between cross-links and gel content) of polymer materials which subsequently define the physical properties (storage and loss moduli, glass transition temperature) that are required for good performance in peel, tack and shear tests. The sustainable approach discussed here is the development of degradable polymer materials featuring selectively degradable linkages in the backbone.
