Vaccines often contain adjuvants to strengthen the response to the vaccine antigen. However, their modes of action at the site of injection (SOI) are poorly understood. Therefore, we assessed the local effects of adjuvant on the innate immune system in mice. We investigated the safe, widely used adjuvants MF59 and aluminum hydroxide (alum), as well as trehalose-6,6'-dibehenate (TDB), Complete Freund's Adjuvant (CFA) and the Toll-Like-Receptor-ligands lipopolysaccharide (LPS) and Pam3CysSerLys4 (Pam3CSK4). We assessed muscle immune cell infiltration after adjuvant injection and observed 16h post immunization (hpi) an increased influx with CFA, MF59 and TDB, but not with alum, LPS or Pam3CSK4...

Tropoelastin (TE), the soluble precursor of insoluble elastin fibers, is produced in minimal amounts in adults. Burn injuries result in inflexible collagen-rich scars because of lack of elastin fiber formation. We studied the feasibility of using recombinant human tropoelastin to enable elastin fiber production in burn and surgical scars to improve skin flexibility. In a swine hypertrophic burn scar model, normal skin and 3 × 3-cm partial thickness thermal burns underwent dermatome resection at 1 week post burn and randomized to four subcutaneous injections of saline or TE (either 0...

Two component injectable hydrogels that cross-link in-situ have been used as non-invasive wound-filling devices, i.e., sealants. These materials carry a variety of functions at the wound sites such as seal leaks, cease unwanted bleeding, bind tissues together, and assist in wound healing process. However, commonly used sealants typically lack antibacterial properties. Since bacterial infection at the wound site is very common, bioadhesive materials with intrinsic antibacterial properties are urgently required...

The only clinically approved alternative to autografts for treating large peripheral nerve injuries is the use of synthetic nerve guidance conduits (NGCs), which provide physical guidance to the regenerating stump and limit scar tissue infiltration at the injury site. Several lines of evidence suggest that a potential future strategy is to combine NGCs with cellular or molecular therapies to deliver growth factors that sustain the regeneration process. However, growth factors are expensive and have a very short half-life; thus, the combination approach has not been successful...

BACKGROUND: Frozen shoulder is not an uncommon disorder, and steroid injection into the glenohumeral (GH) joint is one of the most well-known approaches for the frozen shoulder. However, their results have been varied with beneficial effects or no additional advantage. With the understanding about the pathological changes taking place in frozen shoulder and the biomechanics involved, we wanted to evaluate the short- and long-term efficacy of steroid injection by a novel three-site (NTS) injection technique and compare it with the single-site injection (SSI)...

Based on a platform of strong preclinical data, several studies in humans have demonstrated that inhibiting sclerostin with specific antibodies results in a brisk albeit transient anabolic response in the skeleton without an accompanying increase in bone resorption. Impressive increases in bone mineral density and bone strength have been demonstrated. Other than mild injection site reactions, therapy for up to 2years has been well tolerated. The restriction of sclerostin expression almost exclusively to skeletal tissues, coupled with the absence of recognized medical problems in patients with heterozygous sclerostin deficiency, provides promise that the drug can be used safely...

Robotic systems have slowly entered the realm of modern medicine; however, outside the operating room, medical robotics has yet to be translated to more routine interventions such as blood sampling or intravenous fluid delivery. In this paper, we present a medical robot that safely and rapidly cannulates peripheral blood vessels-a procedure commonly known as venipuncture. The device uses near-infrared and ultrasound imaging to scan and select suitable injection sites, and a 9-DOF robot to insert the needle into the center of the vessel based on image and force guidance...

There are several significant setbacks including limited bioavailability, high clearance, and further current therapies require higher and frequent dosing to gain desired therapeutic effects. Nanomedicines have been widely investigated for rheumatoid arthritis (RA). Though, higher doses also increase the incidence of dreadful adverse effects. Further, nanocarrier properties are tuned by the use of different approaches like varied methods of loading, hydrophilic polymers and targeting ligands, to change the physicochemical properties including higher encapsulation, better penetrating ability to biological barriers, thus preventing the uptake of various nanocarriers by liver and spleen...

The intraoperative identification of certain anatomical structures because they are small or visually occult may be challenging. The development of minimally invasive surgery brought additional difficulties to identify these structures due to the lack of complete tactile sensitivity. A number of different forms of intraoperative mapping have been tried. Recently, the near-infrared fluorescence imaging technology with indocyanine green has been added to robotic platforms. In addition, this technology has been tested in several types of operations, and has advantages such as safety, low cost and good results...
