Membrane-targeted mechanism for amphiphilic vitamin C compounds as methicillin-resistant Staphylococcus aureus biofilm eradicating agents.

Staphylococcus aureus infections and its biofilm removal is an important concern in health care management. Methicillin-resistant S. aureus is responsible for severe morbidity and mortality worldwide.

Functional Assessment of Handwriting Among Children: A Systematic Review of the Psychometric Properties.

Importance: Handwriting legibility and speed assessments have a critical role in identifying and evaluating handwriting problems, which are common among children.

Objective: The objective was to evaluate the psychometric properties and clinical utility of handwriting assessments for children ages 3 to 16 yr.

Data Sources: A systematic review was conducted in CINAHL, PubMed (MEDLINE), Scopus, and education databases, with no time limits.

Nanoemulsions of synthetic rhamnolipids act as plant resistance inducers without damaging plant tissues or affecting soil microbiota.

Plant pathogens and pests can cause significant losses in crop yields, affecting food security and the global economy. Many traditional chemical pesticides are used to combat these organisms. This can lead to the development of pesticide-resistant strains of pathogens/insects and negatively impact the environment.

Surface characterization and interfacial activity of chitinase chi18-5 against chitosan in langmuir monolayers.

One of the challenges for producing active chitinase formulations relies on the gap between the laboratory tests and the biological scenarios where the enzyme will perform its function. In this work, we have employed different Langmuir monolayer arrays to evaluate the interfacial behavior of a recently purified recombinant chitinase, Chi18-5. We have demonstrated that two conformations exist for the chitinase at pH values close to its pI, showing very distinct structural properties at the air/aqueous interface.

Pulsed ultrasound for bone regeneration - outcomes and hurdles in the clinical application: a systematic review.

Impaired bone-fracture healing is associated with long-term musculoskeletal disability, pain and psychological distress. Low-intensity pulsed ultrasound (LIPUS) is a non-invasive and side-effect-free treatment option for fresh, delayed- and non-union bone fractures, which has been used in patients since the early 1990s. Several clinical studies, however, have questioned the usefulness of the LIPUS treatment for the regeneration of long bones, including those with a compromised healing.
