Glycerol, a by-product of biodiesel production through transesterification, presents an opportunity for biodiesel industries to transform surplus glycerol into high-value chemical products. This study focuses on the development of a series of propyl sulfonic acid functionalized (PrSOH) SBA-15 catalysts, synthesized by direct synthesis of 3-mercaptopropyltrimethoxysilane (MPTMS) and tetraethoxysilane (TEOS) in an acidic medium. The catalysts were evaluated for acetylation of glycerol with acetic acid under conditions optimized through response surface methodology.

This investigation developed new composite bone cements using urethane dimethacrylate (UDMA), poly(propylene glycol) dimethacrylate (PPGDMA), and hydroxyethyl methacrylate (HEMA), with micrometer-sized aluminosilicate glass filler. Monocalcium phosphate monohydrate (MCPM) and hydroxyapatite (HA) particles were added to enhance biological performance, particularly osteo-immunomodulation. Free radical polymerization was triggered by mixing two pastes containing either benzoyl peroxide (BPO, an initiator) or N-tolyglycine glycidyl methacrylate (NTGGMA, an activator).

Article Synopsis
  • A recent phase 2A study showed that Atractylodes lancea (AL) significantly reduces tumor progression and mortality in patients with advanced-stage intrahepatic cholangiocarcinoma (iCCA) when administered in doses between 1,000 to 2,000 mg.
  • The study developed a population pharmacokinetic (pop-PK) model to simulate and evaluate different dosage regimens, ultimately recommending a once-daily dose of 2,500 mg for further phase 2B studies.
  • The findings suggest that this pop-PK model can effectively predict dosages and improve clinical study outcomes, potentially minimizing drug development failures.

Existing missing value imputation methods focused on imputing the data regarding actual values towards a completion of datasets as an input for machine learning tasks. This work proposes an imputation of missing values towards improvement of accuracy performance for classification. The proposed method was based on bee algorithm and the use of k-nearest neighborhood with linear regression to guide on finding the appropriate solution in prevention of randomness.

Cholangiocarcinoma (CCA) is a rare disease characterized by malignant cells derived from the epithelial cells of the biliary duct system. Despite extensive treatments, the prognosis for CCA remains poor, emphasizing the critical need for the development of novel treatments. Considerable attention has been directed towards innate immune effector cells, which can recognize tumor cells independently of the major histocompatibility complex, laying the foundation for the development of off-the-shelf drugs.

Beyond Consulting Ltd, 14 Tytherington Park Road, Macclesfield, Cheshire, SK10 2EL, UK.

Aims: The reference nutrient intake for vitamin D in people aged ≥4 years is 10 μg/day (400 IU/day) in the UK, but the recommended daily allowance is 15 μg/day (600 IU/day) for people aged 1-70 years in the USA. Here, we aim to compare the 25-hydroxyvitamin D (25(OH)D) serum concentration profiles between the 2 doses.

Methods: With world-wide trial data of adults aged ≥18 years, 45-93 kg, we constructed a minimal physiologically based pharmacokinetics model of serum concentrations of vitamin D and 25(OH)D using nonlinear mixed effects modelling.

Department of Microbiology and Research and Diagnostic Center for Emerging Infectious Diseases (RCEID), Faculty of Medicine, Khon Kaen University, Khon Kaen, 40002, Thailand.

Acute respiratory tract infection (ARTI) is common in all age groups, especially in children and the elderly. About 85% of children who present with bronchiolitis are infected with respiratory syncytial virus (RSV); however, nearly one-third are coinfected with another respiratory virus, such as human rhinovirus (HRV). Therefore, it is necessary to explore the immune response to coinfection to better understand the molecular and cellular pathways involving virus-virus interactions that might be modulated by innate immunity and additional host cell response mechanisms.
