Dermal defects caused by trauma or disease are challenging to treat due to difficult-to-treat infections that impair wound healing. Due to the widespread emergence of drug-resistant bacteria and dwindling discoveries of new antibiotics, there is currently an urgent need to introduce novel antimicrobials effective against antibiotic-resistant bacteria without causing damage to host tissues. As selenium (Se) and silver (Ag) are known for their antimicrobial properties, we investigated the separate loading of these materials into porous chitosan/PVA (CS) scaffolds through a simple in situ deposition method to create two distinct wound dressing materials (CS-Se and CS-Ag)...

One of the innate features of human behaviour is to enhance personal image in order to look different from the rest of the crowd and to satisfy a need for individualism. People use different dress codes, body makeup and artificial gadgets to improve their personal and physical appearance. The main motive behind all these efforts is personal satisfaction, to appear attractive to others and to overcome phobias and complexes.

We take the first step in extending the integrability approach to one-point functions in AdS/dCFT to higher loop orders. More precisely, we argue that the formula encoding all tree-level one-point functions of SU(2) operators in the defect version of N=4 supersymmetric Yang-Mills theory, dual to the D5-D3 probe-brane system with flux, has a natural asymptotic generalization to higher loop orders. The asymptotic formula correctly encodes the information about the one-loop correction to the one-point functions of nonprotected operators once dressed by a simple flux-dependent factor, as we demonstrate by an explicit computation involving a novel object denoted as an amputated matrix product state...

BACKGROUND: Treatment of severe or chronic skin wounds is an important challenge facing medicine and a significant health care burden. Proper wound healing is often affected by bacterial infection; where biofilm formation is one of the main risks and particularly problematic because it confers protection to microorganisms against antibiotics. One avenue to prevent bacterial colonization of wounds is the use of silver nanoparticles (AgNPs); which have proved to be effective against non-multidrug-resistant and multidrug-resistant bacteria...

Heat acclimation is the best strategy to improve performance in a hot environment. Many athletes seeking the benefits of heat acclimation lack access to a hot environment for exercise, and thus rely on over-dressing to simulate environmental heat stress. It is currently unknown whether this approach produces the requisite thermoregulatory strain necessary for heat acclimation in trained men and women. PURPOSE: To compare physiological and cellular responses to exercise in a hot environment (HOT; 40°C, 30%rh) with minimal clothing (clo= 0...

Burn wounds disrupt the body's primary defense against invasion and colonization by microorganisms. Topical antimicrobials are one component in burn wound care. These agents suppress microbial growth to advantage skin cells and wound healing. Topical antimicrobials can be divided into 2 superclasses: antiseptics and antibiotics. We review the 4 main classes of topical antiseptics (emulsifiers, acids, oxidizers, and heavy metals) and antiseptic-impregnated dressings in current clinical use and address the mechanisms, as well as the advantages and disadvantages of each antiseptic for burn wound management...

Background: For decades, tuberculosis (TB) has posed a great threat to people worldwide. Bone and joint TB is one of the most common types of extrapulmonary TB, with elbow TB comprising a small proportion of these cases. The treatment for elbow stiffness associated with TB has been rarely reported. Patients and methods: We retrospectively analyzed six patients (four females and two males) with tubercular elbow stiffness during a 7-year period. All of them received open arthrolysis and hinged external fixation to restore functional extension, flexion, supination and pronation...

Hip fractures in the elderly are a serious problem for the health service due to the high rate of complications. One of these complications is pressure ulcers that, according to the literature, occur in 8.8% to 55% of patients and mainly arise in the sacral area. The present randomised controlled trial tests whether applying a new innovative multi-layer polyurethane foam dressing (ALLEVYN LIFE™), reduces the onset of pressure ulcers in the sacral area. From March to December 2016, 359 fragility hip fracture patients were randomly divided into 2 groups: 182 in the control group and 177 in the experimental group...

The exactly solvable model of two indistinguishable quantum particles (bosons or fermions) confined in a one-dimensional harmonic trap and interacting via finite-range soft-core interaction is presented and many properties of the system are examined. Particularly, it is shown that independently on the potential range, in the strong interaction limit bosonic and fermionic solutions become degenerate. For sufficiently large ranges a specific crystallization appears in the system. The results are compared to predictions of the celebrated Busch et al...
