Conjugation of PDLA onto MgO microspheres: comparison between solution grafting and melt grafting methods.

Magnesium oxide (MgO) is known for its bioactivity and osteoconductivity when incorporated into biodegradable poly(lactic acid) (PLA), whereas the weak interfacial bonding between MgO microspheres (mMPs) and PLA often leads to suboptimal composite properties with uncontrollable functionality. Conjugation of mMPs with PLA may offer a good way to enhance their compatibility. In this study, we systematically investigated two grafting techniques, solution grafting (Sol) and melt grafting (Mel), to decorate poly (D-lactic acid) (PDLA) on mMPs pre-treated by prioritized hydration to obtain Sol MPs and Mel MPs, in order to optimize the grafting efficiency and improve their controllability in the properties including the crystal structure and surface morphology.

Sequence-Defined DNA Polymers: New Tools for DNA Nanotechnology and Nucleic Acid Therapy.

ConspectusStructural DNA nanotechnology offers a unique self-assembly toolbox to construct soft materials of arbitrary complexity, through bottom-up approaches including DNA origami, brick, wireframe, and tile-based assemblies. This toolbox can be expanded by incorporating interactions orthogonal to DNA base-pairing such as metal coordination, small molecule hydrogen bonding, π-stacking, fluorophilic interactions, or the hydrophobic effect. These interactions allow for hierarchical and long-range organization in DNA supramolecular assemblies through a DNA-minimal approach: the use of fewer unique DNA sequences to make complex structures.

A Rare Case of a Primary Non-parasitic Splenic Cyst Removed via Laparoscopic Intervention.

Splenic cysts are differentiated into primary and secondary cysts based on epithelial lining. Primary non-parasitic epithelial splenic cysts are extremely rare. We report a case of a 24-year-old male with left hypochondrial swelling with no history of abdominal trauma.

Advancing modified biochar for sustainable agriculture: a comprehensive review on characterization, analysis, and soil performance.

Biochar is a carbon-rich material produced through the pyrolysis of various feedstocks. It can be further modified to enhance its properties and is referred to as modified biochar (MB). The research interest in MB application in soil has been on the surge over the past decade.

CLINICAL EFFICACY OF ORAL AZITHROMYCIN VERSUS OTHER ANTIMICROBIAL DRUGS IN THE TREATMENT OF TYPHOID PATIENTS ACROSS ALL AGE GROUPS: A SYSTEMATIC REVIEW OF RANDOMIZED CONTROLLED TRIALS.

Background: Typhoid is a major health concern. Drug-resistant cases of typhoid have given rise to new debates. Azithromycin has shown adequate results.
