is used in Mexican folk medicine to treat wounds on the skin. Recently, it was shown that the essential oil (EO) of has wound healing activity, accelerating cutaneous wound closure and generating scars with good tensile strength. α-pinene (PIN) and α-phellandrene (FEL) are terpenes that have been found in this EO, and it has been shown in different studies that both have anti-inflammatory activity. The aim of this study was to determine the wound healing activity of these two terpenes. The results of in vitro tests demonstrate that PIN and FEL are not cytotoxic at low concentrations and that they do not stimulate fibroblast cell proliferation. In vivo tests showed that the terpenes produce stress-resistant scars and accelerate wound contraction, due to collagen deposition from the early stages, in wounds treated with both terpenes. Therefore, we conclude that both α-pinene and α-phellandrene promote the healing process; this confirms the healing activity of the EO of , since having these terpenes as part of its chemical composition explains part of its demonstrated activity.

Staphylococcus aureus vesicles impair cutaneous wound healing through p38 MAPK-MerTK cleavage-mediated inhibition of macrophage efferocytosis.

Background: Staphylococcus aureus, a known contributor to non-healing wounds, releases vesicles (SAVs) that influence the delicate balance of host-pathogen interactions. Efferocytosis, a process by which macrophages clear apoptotic cells, plays a key role in successful wound healing. However, the precise impact of SAVs on wound repair and efferocytosis remains unknown.

Burns are complex traumatic injuries that lead to severe physical and psychological problems due to the prolonged healing period and resulting physical scars. Owing to their versatility, hydrogels can be loaded with various functional factors, making them promising wound dressings. However, many hydrogel dressings cannot support cell survival for a long time, thereby delaying the process of tissue repair.

Epithelial‒mesenchymal transition (EMT) in retinal pigment epithelial (RPE) cells is believed to play a key role in the pathogenesis of proliferative vitreoretinopathy (PVR). The ability of Hirudo to promote blood flow and dispel blood stasis may be related to its anti-EMT effects. Through the use of a network pharmacology method, the mechanism by which Hirudo treats PVR was investigated in this study, and the findings were confirmed through in vitro cellular tests.

Background: Colorectal cancer (CRC) is the second-leading cause of cancer-related deaths. Curcumin has been reported to have suppressive effects in CRC and to address the physiological limitations of curcumin, a chemically synthesized curcuminoid analog, known as (2E,6E)-2,6-Bis (2,3-Dimethoxy benzylidine) cyclohexanone (DMCH), was developed and the anti-metastatic and anti-angiogenic properties of DMCH in colorectal cell line, SW620 were examined.
Methods: The anti-metastatic effects of DMCH were examined in the SW620 cell line by scratch assay, migration, and invasion assay, while for anti-angiogenesis properties of the cells, the mouse aortic ring assay and Human Umbilical Vein Endothelial Cells (HUVEC) assay were conducted.

Background: Women with inflammatory bowel disease (IBD) face complexities of disease management during pregnancy and childbirth. Apprehension regarding vaginal delivery in pregnant individuals with IBD persists due to concern for perianal disease and perineal trauma. The incidence of poor wound healing after obstetric anal sphincter injury is approximately 4% in the general population.
