Proximal peroneal perforator flap, cadaveric study, and clinical applications for shallow defect reconstructions.

Purpose: Peroneal artery perforator offers a versatile range of microvascular tissue transfer methods from local flaps to vascularized osteocutaneous fibula flaps. It is one of the few flaps that can cover shallow defects that require thin and pliable skin paddles, such as in hands and feet (Han et al., 2018).

Novel, user-friendly landmarks for localizing Baxter's nerve: A cadaveric study.

Introduction: Identification of Baxter's nerve (BN) has proven challenging for less experienced practitioners using ultrasonography due to a lack of adequate landmarks. This study aimed to establish novel, user-friendly anatomical landmarks and to describe useful structures to localize BN.

Materials And Methods: We examined 10 fresh cadaveric feet and identified the interobserver agreement of measuring three surface landmarks: the most medially protruded point on the medial malleolus (P), the navicular tuberosity (Q), and the center of the calcaneus (B).

extract-loaded nanoemulsion improves the survival of endotoxemic mice by inhibiting nitric oxide-dependent HMGB1 release.

Background: High mobility group box 1 (HMGB1) is a well-known damage-related alarmin that participates in cellular inflammatory responses. However, the mechanisms leading to HMGB1 release in inflammatory conditions and the therapeutic agents that could prevent it remain poorly understood. This study attempted to examine whether the herb, which is known to have anti-inflammatory property, can modulate cellular inflammatory responses by regulating HMGB1 release.

Subcritical water-hydrolyzed fish collagen ameliorates survival of endotoxemic mice by inhibiting HMGB1 release in a HO-1-dependent manner.

To investigate potential mechanisms underlying the bioactivity of hydrolyzed fish collagen, we examined the anti-inflammatory actions of subcritical water-hydrolyzed fish collagen (SWFC) in lipopolysaccharide (LPS)-triggered inflammation and endotoxemia. SWFC markedly inhibited LPS-stimulated release of high mobility group box 1 (HMGB1) in murine RAW264.7 macrophages, along with decreased cytosolic translocation of HMGB1.

Sphingosine 1-phosphate (S1P) receptor subtypes S1P1 and S1P3, respectively, regulate lymphocyte recirculation and heart rate.

Sphingosine 1-phosphate (S1P) influences heart rate, coronary artery caliber, endothelial integrity, and lymphocyte recirculation through five related high affinity G-protein-coupled receptors. Inhibition of lymphocyte recirculation by non-selective S1P receptor agonists produces clinical immunosuppression preventing transplant rejection but is associated with transient bradycardia. Understanding the contribution of individual receptors has been limited by the embryonic lethality of the S1P(1) knock-out and the unavailability of selective agonists or antagonists.
