Determination of poly(3-hydroxybutyrate) using a combination of enzymatic spectrophotometry and alkaline hydrolysis

open access: yes, 2006
A combination of enzyme-based spectrophotometric analysis and alkaline hydrolysis was developed for the measurement of poly(3-hydroxybutyrate) (PHB). The principle of the determination is as follows: alkaline hydrolysis decomposes PHB into its monomer ...

Crystalline Poly(L‐Lactic Acid) Nanoparticles via Nonsolvent‐Induced Cascade Phase Separation

open access: yesJournal of Polymer Science, EarlyView.
Water is used as the nonsolvent to induce liquid/liquid phase separation (LLPS) of poly(L‐lactic acid) (PLLA)/propylene carbonate solution and PLLA crystallization. Due to the two levels of cascade LLPS coupled with confined PLLA crystallization, three types of polymeric nanoparticles, including PLLA single crystals, Ouzo crystalsomes, and sheaf‐like ...

The effect of gamma radiation on mechanical properties of biodegradable polymers poly(3-hydroxybutyrate) and poly(3-hydroxybutyrate-co-3-hydroxyvalerate)

open access: yesMaterials Research, 2013
Brazilian poly(3-hydroxybutyrate), P(3-HB), and its copolymer, poly (3-hydroxybutyrate-co-3-hydroxyvalerate), P(3-HB-co-3-HV) were irradiated with gamma radiation (60Co) at room temperature and in the presence of oxygen. The viscosity-average molar mass (

Proteo‐transcriptomic insights into the venom composition of the ectoparasitoid Eupelmus urozonus

open access: yesPest Management Science, EarlyView.
Integrated venom‐gland transcriptomics and venom proteomics of Eupelmus urozonus identified 316 venom proteins, including 75 secreted candidates, revealing diverse hydrolases, proteases/inhibitors and many uncharacterized effectors. Abstract BACKGROUND Ectoparasitoid venoms are ‘cocktails’ of bioactive molecules injected during oviposition to paralyze ...

Research Trends and Mechanistic Insights Into Natural Medicines for Alzheimer's Disease: A Bibliometric Analysis and Narrative Review

open access: yesPhytotherapy Research, EarlyView.
Research landscape and mechanistic insights into natural medicines for Alzheimer's disease. ABSTRACT Natural medicines have been widely investigated for Alzheimer's disease (AD), but the development of this field and the relationship between bibliometric themes and experimental evidence remain insufficiently characterized.

Three‐Dimensional Piezoelectric Fibrous Constructs for Muscle Regeneration

open access: yesSmall, EarlyView.
This study fabricates 3D piezoelectric PHBV scaffolds to enhance muscle regeneration by systematically tuning electrospinning parameters. Introducing porosity yields a 25‐fold enhancement in the effective piezoelectric coefficient (d33). A highly effective d33 signal, activated by cellular tension and fiber deformation, significantly improves myogenic ...

Outcomes of Long‐Term Absorbable Mesh Use for Ventral Hernia Repair in Immunosuppressed Patients

open access: yesWorld Journal of Surgery, EarlyView.
Immunosuppressed patients are more at risk of perioperative infections. In case of ventral hernia repair, the use of a long‐term absorbable mesh could potentially decrease the infectious risk in these patients. This study aimed to assess the short‐ and mid‐term outcomes of ventral hernia repair with long‐term absorbable mesh in immunosuppressed and non‐

Iterative phase retrieval in macromolecular crystal diffraction using the gradients of intensities

open access: yesJournal of Applied Crystallography, EarlyView.
Incorporating molecular intensity gradients into an iterative projection algorithm enables model‐free electron‐density reconstruction even for low‐solvent macromolecular crystals.Iterative phase retrieval (IPR) offers a model‐independent route to crystallographic structure determination but is fundamentally limited by the sampling of the diffraction ...
