Fused filament fabrication (FFF) has been widely used in various industries, and the adoption of technology is growing significantly. However, the FFF process has several disadvantages like inconsistent part quality and print repeatability. The occurrence of manufacturing-induced defects often leads to these shortcomings.

Roselle ( L.) is recognized for its phytochemical compounds such as anthocyanins, which possess pharmacological potentials in the treatments of hypertension, diabetes, cancer, hyperlipidaemia and hyperglycaemia. The calyx is the most commercially valuable part of the roselle and usually harvested at maturation.

Article Synopsis
  • The study assesses the reliability of the Biosculptor's Bioscanner for measuring volume changes in transtibial amputees' residual limbs during walking activities.
  • Both active and nonactive amputees showed significant variations in circumferences after walking, particularly an initial increase at the limb's distal end, which then decreased over time.
  • Results indicate a strong correlation between the Bioscanner and traditional tape measure methods, suggesting the Bioscanner could be a valid alternative for monitoring limb volume changes.

Objectives: We compared the smoking prevalence, smoking knowledge, attitudes and practices (S-KAP) between smoke-free campuses (SFCs) and non-SFCs (NSFCs) and determined the associated factors of smoking status and S-KAP.

Design: Cross-sectional study.

Settings: The research was conducted in four public universities in Malaysia; two SFCs and two NSFCs.

The Biosculptor's CNC milling machine, the Biomill, offered four different surfaces machined on positive models. This study aims to adopt the surface topography method in characterizing the four different surface roughness of polyethylene Pe-Lite liner as a product of the Biomill. Three surface parameters chosen were the arithmetic average (Ra), root mean square roughness (Rq), and ten-point height (Rz).

Introduction: The Joint Committee of Infant Hearing (JCIH) recommended hearing screening by one month of age, diagnosis of hearing loss by three months of age, and intervention initiated by six months of age. In Malaysia however, the age of diagnosis of hearing loss in children is relatively late. This study aimed to identify the challenges faced by parents in seeking a diagnosis of hearing loss for their children.

Background: In combating the increasing trend of non-communicable diseases (NCDs) over the last two decades in the country, the Ministry of Health Malaysia developed the Enhanced Primary Health Care (EnPHC) initiative to improve care management across different levels of the public service delivery network. An evaluation research component was embedded to explore the implementation issues in terms of fidelity, feasibility, adaptation and benefit of the initiative's components which were triage, care coordination, screening, risk management and referral system.

Methods: A mixed methods study was conducted at 20 participating EnPHC clinics in Johor and Selangor, two months after the intervention was initiated.

Article Synopsis
  • The study evaluated the accuracy and usability of the Biosculptor's Bioscanner for measuring transtibial residual limb circumference during walking.
  • The Bioscanner's measurements were compared to traditional tape measure methods, showing only small differences in results, particularly around the mid-patella tendon.
  • Findings indicated that the Bioscanner is a reliable, portable device that can serve as an effective tool for monitoring amputee limb measurements and enhancing pre-prosthetic training.

Article Synopsis
  • The interaction between the anticancer drug vandetanib (VDB) and the ligand transporter lysozyme (LYZ) was studied using various spectroscopic techniques and computational analysis to confirm their complex formation.
  • The findings revealed that VDB binds to LYZ through weak interactions, characterized by a binding constant and thermodynamic parameters indicating the role of hydrophobic and van der Waals forces, along with hydrogen bonds.
  • Additionally, VDB enhances the thermal stability of LYZ while its binding site is near the LYZ active site, with certain metal ions like Mg, Ba, and Zn disrupting this interaction.
