Background And Aim: activity evaluation of Egyptian leaves extracts, and healing activity assessment of the newly prepared ointment of leaves extracts mingled with Shea butter.
Experimental Procedure: Different extraction methods and solvents were used to extract Egyptian bioactive agent(s). Antibacterial, scavenging activity and evaluation of wound repair potentiality of extract were examined in normal and diabetic experimental rat models with induced circular excisions.
Results And Conclusion: Olive leaves extract of Tanta was selected as the most active agent against Methicillin-resistant (MRSA), with MIC value 15.6 μg/ml. Moreover, checkerboard dilution technique approved that the interaction between Tanta LEM crude extract and Ciprofloxacin was synergistic. Scavenging activity of the extract against DPPH free radicals was 87.55% at concentration of 50 μg/ml. normal and diabetic experimental rats treated with Shea butter: Tanta LEM extract (1:3 w/v) showed the maximum wound contraction and healing activity.

Background: Complex perianal fistulas, challenging to treat and prone to recurrence, often require surgical intervention that may cause fecal incontinence and lower quality of life due to large surgical wounds and potential sphincter damage. Human umbilical cord-derived MSCs (hUC-MSCs) and their exosomes (hUCMSCs-Exo) may promote wound healing.
Methods: This study assessed the efficacy, mechanisms, and safety of these exosomes in treating complex perianal fistulas in SD rats.

Endochondral ossification (EO) is a pivotal process during fracture healing and traumatic heterotopic ossification (HO), involving the cartilaginous matrix synthesis and mineralization. Unlike the extracellular matrix, the hyaluronan (HA)-rich pericellular matrix (PCM) directly envelops chondrocytes, serving as the frontline for extracellular signal reception and undergoing dynamic remodeling. Pentraxin 3 (PTX3), a secreted glycoprotein, facilitates HA matrix assembly and remodeling.

Objective: Varicose vein ablation is generally indicated in patients with active/healed venous ulcers. However, patient selection for intervention in individuals without venous ulcers is less clear. Tools that predict lack of clinical improvement (LCI) following vein ablation may help guide clinical decision-making but remain limited.

Takifugu bimaculatus, a pufferfish species farmed in Fujian Province, is known for its non-toxic flesh and collagen-rich skin. We identified a novel collagen-derived matrix metalloproteinase 1 (MMP-1) inhibitory peptide, from T. bimaculatus skin with potent anti-photoaging properties.

Diabetes is associated with excessive inflammation, which negatively impacts the fracture healing process and delays bone repair. Previously, growing evidence indicated that activation of the nod-like receptor (NLR) family, such as nod-like receptor thermal protein domain-associated protein 3 (NLRP3) inflammasome induces a vicious cycle of chronic low-grade inflammatory responses in diabetic fracture. Here, we describe the synthesis of a bone adhesive hydrogel that can be locally injected into the fracture site and releases a natural inhibitor of NLRP3 (rutin) in response to pathological cue reactive oxygen species activity (ROS).
