Objectives: This study aimed to examine physical and craniofacial growth patterns in preschool-aged children with microcephaly and evaluate their potential clinical significance.
Methods: A total of 130 children (76 boys, 54 girls) aged 1-5 years with microcephaly (head circumference <-3 standard deviations) were enrolled in this prospective study at a tertiary care hospital, with 130 age- and sex-matched healthy controls. Nine craniofacial dimensions (head circumference, head length, head width, physiognomic facial length, morphological facial length, minimum frontal diameter, bizygomatic diameter, bigonial diameter, and total jaw height) were measured every six months using standardized techniques and instruments.

This study demonstrates the successful fabrication of nanostructured Langmuir-Blodgett (LB) films combining the conjugated copolymer poly(9,9-dioctylfluorene--3,4-ethylenedioxythiophene) (PDOF--PEDOT) with spherical and triangular silver nanoparticles (AgNP). The LB technique allowed precise control over the molecular arrangement and distribution of the nanoparticles at the air-water interface, resulting in compact, reproducible and structurally ordered nanocomposite films. The structural and morphological properties of the interfacial monolayers and LB films were investigated using surface pressure-area isotherms, Brewster angle microscopy, polarization modulation infrared reflection-absorption spectroscopy (PM-IRRAS) and quartz crystal microbalance.

Objectives: Antibiotic resistance towards penicillin has been attempted to counter by chemically modifying ampicillin through the conjugation with silver nanoparticles (AgNPs). The current study optimizes the conditions for synthesizing and characterizing AgNP-ampicillin to quantify the conjugation extent, evaluate the antibacterial efficacy, and explore the underlying antibacterial mechanisms.
Materials And Methods: AgNPs were synthesized from silver nitrate by chemical reduction method, silica-coated with tetraethyl orthosilicate (TEOS) and amine functionalized by (3-aminopropyl) triethoxysilane (APTES), which was then conjugated with ampicillin via the carbodiimide chemistry.

Dental waste, including metal, plastic, and chemical residues, and high energy and water consumption, significantly contribute to environmental degradation. This review highlights the environmental impact of common dental materials and practices, such as amalgam, resin composites, and disposable plastics. The aim is to examine current evidence, emphasizing mercury pollution, microplastic release, and biomedical waste handling.

The monolayer transistor, where the semiconductor layer is a single molecular layer, offers an ideal platform for exploring transport mechanisms both theoretically and experimentally by eliminating the influence of spatially correlated microstructure. However, the structure-property relations in polymer monolayers remain poorly understood, leading to low transistor performance to date. Herein, a self-confinement effect is demonstrated in the polymer monolayer with nanofibrillar microstructures and edge-on orientation, as characterized by the 4D scanning confocal electron diffraction method.
