Purpose:
Hair disorders, which are often attributed to conditions associated with a shortened anagen growth phase, oxidative stress, and hormonal dysregulation, especially during aging, have profound psychological implications. Currently, only minoxidil has been approved as a topical hair growth solution; thus, alternative therapies for treating hair loss and promoting hair health are urgently needed. Herein, we aimed to develop and assess a novel method to promote hair growth and health using mastic (Pistacia lentiscus) gum and peppermint (Mentha piperita L.) extracts.
Materials and Methods:
After determining the optimal ratio of mastic gum and peppermint extracts, we performed in vitro and in vivo experiments to verify the efficacy of the 7:3 mastic gum-peppermint mixture (MP73; FHH-MG) for enhancing hair growth and health.
Results:
Mastic gum significantly promoted cell proliferation and demonstrated synergistic benefits when combined with peppermint extract. In vitro, FHH-MG increased human dermal follicle papilla cell proliferation and demonstrated anti-inflammatory and antioxidant effects. In vivo, treatment with FHH-MG dose-dependently enhanced hair growth and gloss and increased the expression of vascular endothelial growth factor, epidermal growth factor, β-catenin, and insulin-like growth factor-1 in C57BL/6 mice compared to the negative control.
Conclusion
The novel mixture exhibited hair growth-promoting effects in C57BL/6 mice; thus, FHH-MG may serve as a botanical alternative for hair growth and health promotion.

Two small-breed dogs were referred to the Veterinary Medical Teaching Hospital of Chonnam National University for the treatment of dentigerous cysts associated with the mandibular canines. In both cases, conscious oral examinations revealed progressive gingival swelling and dark blue discoloration around the unerupted left mandibular canines. Intraoral dental radiographs showed horizontally unerupted canines, fluid accumulation between the cyst-involved teeth and the alveolar bone, and significant alveolar bone loss. Surgical removal of the dentigerous cyst and the affected teeth can lead to complications, including mandibular fractures, particularly in small dogs due to the higher tooth root-to-mandible ratio. Guided bone regeneration (GBR) was employed in these cases to prevent these complications. The procedure involved placing bone xenografts into the extraction sockets of the left mandibular canine tooth, followed by covering the sockets with an absorbable collagen membrane. After surgery, the surgical site was successfully filled with bone graft material and newly formed bone with no complications. Thus, GBR proved to be an effective technique for preventing mandibular fractures and increasing stability in cases of severe alveolar bone loss in small-breed dogs.

The number of migrant workers is increasing worldwide every year, and their number and role in Korean society is also increasing. However, the poor conditions faced by migrant workers often become a social issue, and it is not uncommon for them to be the subject of forensic autopsies. This study aimed to investigate the current status of medicolegal autopsy on migrant workers in Korea. We collected data of medicolegal autopsies on migrant workers conducted in Korea from 2016 to 2020 by requesting data from the institutions performing medicolegal autopsy. We calculated the autopsy rate and analyzed manner of death and cause of death. The medicolegal autopsy rate for foreign deaths was 16.4%, which was more than five times higher than the autopsy rate for Korean deaths. By manner of death, 43.7% were natural death, 6.4% were homicides, 8.5% were suicides, 23.6% were accidental deaths, 2.7% were undetermined unnatural deaths and 15.0% were unknown. These results showed a high rate of homicide, accidental death, and unknown death compared to Korean. And the proportion of industrial accident deaths and sudden manhood death syndrome were high. Through this study, it was confirmed that medicolegal autopsies are performed at a relatively high frequency when migrant workers die, and the characteristics related to the deaths of migrant workers were identified.

Sudden death during or after percutaneous coronary intervention (PCI) could be led to potential medicolegal disputes. This study aimed to investigate the clinical and postmortem findings in PCI-related deaths-focusing on the current statusto inform preventive strategies against these fatalities. Forty-three cases were retrieved from the National Forensic Service's postmortem records between 2015 and 2021, and the corresponding postmortem findings and clinical information were analyzed. The analyses revealed a relatively consistent annual incidence of PCI-related deaths. Immediate deaths during or shortly after PCI occurred in 17 cases (39.5%), and delayed PCI-related deaths after discharge from the hospital occurred in 26 cases (60.5%). The causes of PCI-related deaths in the postmortem cases were categorized into four groups: PCI complications (11 cases, 26%), acute myocardial infarction (23 cases, 53%), ischemic heart disease (8 cases, 19%), and others (1 case, 2%). Postmortem examinations played a critical role in determining the cause of death and obtaining medical evidence, including pathological findings of the heart as well as those of coronary artery and stent insertion. Our findings suggest that a detailed examination of the heart, coronary arteries, stent status, and atherosclerosis in PCI-related deaths could help provide more accurate information as medical evidence and prevent/resolve potential medicolegal issues. Further, this could advance our understanding of PCI-related deaths and inform future preventive strategies.

Lipid-coated microbubbles are widely used as an ultrasound contrast agent, as well as drug delivery carriers. However, the two main limitations in ultrasound diagnosis and drug delivery using microbubbles are the short half-life in the blood system, and the difficulty of surface modification of microbubbles for active targeting. The exosome, a type of extracellular vesicle, has a preferentially targeting ability for its original cell. In this study, exosome-fused microbubbles (Exo-MBs) were developed by embedding the exosome membrane proteins into microbubbles. As a result, the stability of Exo-MBs is improved over the conventional microbubbles. On the same principle that under the exposure of ultrasound, microbubbles are cavitated and self-assembled into nano-sized particles, and Exo-MBs are self-assembled into exosome membrane proteins-embedded nanoparticles (Exo-NPs). The Exo-NPs showed favorable targeting properties to their original cells. A photosensitizer, chlorin e6, was loaded into Exo-MBs to evaluate therapeutic efficacy as a drug carrier. Much higher therapeutic efficacy of photodynamic therapy was confirmed, followed by cancer immunotherapy from immunogenic cell death. We have therefore developed a novel ultrasound image-guided drug delivery platform that overcomes the shortcomings of the conventional ultrasound contrast agent and is capable of simultaneous photodynamic therapy and cancer immunotherapy.
