An increasing number of minimally invasive cosmetic procedures, such as filler or botulinum toxin injections, are performed annually. These procedures are associated with a high risk of post-procedure bruising or ecchymosis. Ecchymoses arise following hemorrhage and extravasation of red blood cells into the subcutaneous tissue, leading to local skin discoloration. Although ecchymoses generally resolve within 14 days, their appearance is cosmetically bothersome, and they may be painful and cause major distress to patients. Recent clinical evidence suggests that light/laser technology with pulsed dye laser (PDL) or intense pulsed light (IPL) can dramatically alleviate and minimize bruising when delivered within 24-72 hr of the injection. This article, will review reports of treatment of ecchymosis by lasers and IPL.

An imbalance in iron homeostasis contributes to mitochondrial dysfunction, which is closely linked to the pathogenesis of various diseases. Herein, we developed a nanosensor for detecting mitochondrial ferrous ions in vitro and in vivo. A poly(N-isopropylacrylamine)-coacrylic acid nanohydrogel was synthesized, and ferrous ions were detected using the fluorescent probe FeRhonox-1 embedded within it.

Here, we investigated whether a mixture of and (1:3, KGC01CE) could suppress muscle atrophy in HO-induced C2C12 cells and dexamethasone-injected mice. Our results revealed that KGC01CE effectively safeguarded against HO-induced muscle atrophy in C2C12 cells compared with the same mixture at other ratios. We demonstrated that dexamethasone elicited oxidative stress in muscle tissue and decreased the grip strength and cross-sectional areas of muscle fibers; however, oral administration of KGC01CE (1:3) suppressed these dexamethasone-induced changes.

A close interplay exists between the gut and liver, known as the "gut-liver axis", which plays a vital role in health and disease. This research aimed to explore the effects of dietary formic acid polymer (FAP) addition on inflammatory injury in gut-liver axis of broilers due to lipopolysaccharide (LPS) challenge. Four hundred and fifty 1-day-old male Arbor Acres broilers were assigned to three treatment groups: (1) control (non-challenged, basal diet); (2) LPS (LPS-challenged, basal diet); (3) LPS+FAP (LPS-challenged, basal diet with 1,000 mg/kg FAP).

Arthropathy is a common complication in haemophilia and decreases quality of life. It has been known that concentrations of β-hydroxybutyrate (BHB) in blood are increased by a ketogenic diet, and elevated levels of circulating BHB restricts the progression of inflammation-mediated joint pathological changes. We hypothesized that elevation of blood BHB concentrations could be effective for reducing the progression of bleeding-induced arthropathy by moderating the inflammatory responses of macrophages.

Background: Mesenchymal stromal cell (MSC) therapy commonly involves systemic infusion of MSCs, which undergo apoptosis in the lung and induce immunoregulatory macrophages that reduce disease. The relevance of this mode of action, however, is yet to be determined for MSCs administered via other routes. Here, we administered MSCs via subcutaneous (SC) injection into inflamed tissue and investigated the immunomodulatory effects on the local lymph node (LN), which is a major site for the initiation and regulation of immune responses.
