Volumizing and Cogged Threads for Nose Augmentation.

BACKGROUND: Nose augmentation using nonsurgical methods, including volumizing and cogged threads, has gained popularity due to its minimally invasive nature, shorter recovery times, and reduced risks compared to traditional rhinoplasty. However, there is limited literature on the use of these techniques in the Asian population. AIMS: This study aims to present two successful cases of nose augmentation using volumizing and cogged threads, providing evidence of their effectiveness and demonstrating the insertion techniques through a supplementary video. PATIENTS/METHODS: Two female patients (aged 26 and 33) underwent nonsurgical nose augmentation. The first patient received volumizing threads to enhance nasal contour, while the second patient received cogged threads to refine the nasal tip and alar base. Both procedures were performed using polydioxanone (PDO) threads, with follow-ups conducted to assess the outcomes. RESULTS: Both patients exhibited significant improvement in nasal contour and projection, with outcomes maintained for up to 8 months post-procedure. The patients reported high satisfaction with the aesthetic results, and no complications were observed during the follow-up period. CONCLUSIONS: Volumizing and cogged threads offer a promising nonsurgical alternative for nose augmentation, particularly in patients seeking minimal invasiveness and natural-looking results. While the initial outcomes are positive, further research is needed to evaluate the long-term safety and effectiveness of these techniques, especially in the Asian demographic.

The Impact of Pinus koraiensis Leaf Extract Consumption on Postprandial ApoB100 and Lipid Metabolism: A Randomized, Double-Blind, Placebo-Controlled Trial in Healthy Participants Subjected to an Oral High-Fat Challenge.

Pinus koraiensis (PK) leaf extract, derived from Korean pine byproducts, holds promise for alleviating postprandial hyperlipidemia. In this study, we investigated the potential of PK leaf extract for modulating postprandial hyperlipidemia in adults with normal or borderline fasting triglyceride levels. In a randomized, double-blind, parallel design, 70 subjects were randomly assigned to either the placebo or PK group for 4 weeks. After 4 weeks of consuming PK leaf extract, the results indicated a trend toward decreased serum apolipoprotein B-100 (ApoB100) levels 2 h after a high-fat challenge. Furthermore, significant improvements were observed in the incremental area under the curve (iAUC) at 0-4 h and 2-4 h compared to baseline, particularly among individuals with a higher body weight (>61.35 kg) and daily caloric intake (>1276.5 kcal). Based on these findings, PK leaf extract may have beneficial effects on postprandial lipoprotein metabolism, especially among individuals with a relatively high body weight and caloric intake.

Anatomical perspectives of brow-lifting using threads: Clinical cases with techniques.

INTRODUCTION: Tailoring surgical interventions to target age-related transformations is paramount. Many candidates seeking blepharoplasty commonly exhibit eyebrow ptosis, underscoring the necessity for surgeons to possess a comprehensive understanding of techniques for brow and forehead rejuvenation. METHODS: Various surgical techniques are available for eyebrow and forehead enhancement, contrasting the standardized approaches in upper and lower blepharoplasty. Thread lifting has gained popularity for forehead lifting, although a more precise term would be eyebrow lifting. The thread lifting methods using V and I techniques with floating-type threads (Secret Line, Hyundai Meditech., Inc., Wonju-si, Republic of Korea) are used. RESULTS: The natural aging process often causes the forehead and eyebrows to sag under the influence of gravity, leading to the appearance of heavy eyelids. Elevating the eyebrows can mitigate droopiness, enhance vision clarity, and rejuvenate the facial aesthetic. While non-surgical methods like Botulinum Toxin A can weaken muscles and potentially aid in brow elevation, their visible effects may be somewhat constrained. DISCUSSION: Surgical methods encompass endoscopic forehead lift, eyebrow lift techniques, and scalp excision-based forehead reduction surgery, each with specific advantages and drawbacks. Thread lifting bridges the gap between surgical and non-surgical modalities. Forehead areas often lack subcutaneous fat, requiring precise anatomical understanding for effective thread lifting. Cannula usage with partial tunneling ensures efficacy even in patients with strong adhesions. Presented cases showcase successful eyebrow lifting using cog threads, illustrating immediate and gradual post-procedure changes. CONCLUSION: Eyebrow thread lifting demands periodic procedures, offering subtler improvements than surgery. Anatomical knowledge is crucial, and the technique presents discomfort. Effects last about 6 months, requiring re-treatment as effects regress. Thread lifting, a middle ground between surgical and non-surgical methods, can rejuvenate brows with less downtime.

Reverse and antegrade vector thread lifting techniques: Correcting nasolabial and marionette lines.

BACKGROUND: This study evaluates the efficacy of reverse and antegrade thread lifting vectors in conjunction with thread selection for correcting nasolabial folds and marionette lines, aiming to enhance treatment precision and effectiveness. METHODS: Three female patients aged 43, 48, and 53, presenting with primary concerns regarding nasolabial folds, underwent distinct treatment regimens utilizing various types of threads and vectors. Additionally, video demonstrations were recorded to showcase the procedural techniques employed in each case. RESULTS: The outcomes of the thread lifting procedures demonstrated significant improvements in the correction of the nasolabial fold and marionette line. CONCLUSION: Innovative thread insertion techniques involve entry points above the zygomatic arch and threading toward the temple hairline for lateral face lifting. These utilize barbs to pull skin and underlying tissues. The reversal technique involves inserting threads in a criss-cross pattern, forming a fibrous structure that may prolong the duration of results. Various thread combinations, considering factors such as composition, thickness, and barb size, provide customized procedures. This research introduces clinical applications, including temple area hairline lifting for nasolabial fold and marionette line correction, reverse vectors targeting nasolabial folds and marionette lines, and antegrade approaches from the lateral side.

Novel single-entry point injection technique for masseter hypertrophy treatment using botulinum neurotoxin based on patient-reported comfort.

INTRODUCTION: Botulinum neurotoxin (BoNT) injections are widely used for the treatment of masseter muscle hypertrophy in Southeast Asia. However, there remains a lack of consensus regarding the optimal injection technique. This study aimed to compare the efficacy and patient discomfort associated with single-entry point injections versus multiple three-point injections for masseter muscle hypertrophy treatment with BoNT. MATERIALS AND METHODS: Sixteen participants, comprising both male and female Korean adults aged 22-63, were enrolled in the study. On the left side of the face, single-entry point injections were administered, followed by multidirectional injections, while on the right side, three-point injections were given. Pain intensity during the procedure was assessed using visual analogue scale scores. RESULT: Our results revealed that participants experienced lower levels of pain with single-entry point injections compared to three-point injections (average visual analogue scores of 3.31 and 5.19, respectively). CONCLUSION: These findings highlight the potential benefits of single-entry point injections in reducing patient discomfort during masseter muscle hypertrophy treatment with BoNT. We advocate for further research to validate these findings and encourage practitioners to consider single-entry point injections as a viable option for enhancing treatment outcomes in their clinical practice.

Volumizing Threads (Jamber) in the Midface and Managing Side Effects: Clinical Cases.

The clinical application of polydioxanone (PDO) threads, traditionally utilized for tissue lifting, is now being explored for its volumizing effects in midface rejuvenation. The novel approach involves employing PDO volumizing threads to achieve physical augmentation akin to a "solid filler." The study introduces a more convenient insertion method for these threads, prioritizing ease and efficacy. Clinical cases demonstrate the efficacy of volumizing threads in addressing midface concerns, such as nasolabial folds and midcheek grooves. Additionally, the integration of volumizing threads to provide support in sagging areas is examined for achieving natural-looking enhancements. While highlighting positive outcomes, potential side effects like thread protrusion are addressed, along with strategies for their mitigation. Volumizing threads are presented as a suitable procedure for patients wary of traditional fillers or seeking subtle enhancements, with the recommendation of combining them with cog threads for those desiring more pronounced changes in facial contour. In summary, volumizing thread offers a minimally invasive alternative with fewer side effects for midface rejuvenation.

Impact of Long-Term Supplementation with Probiotics on Gut Microbiota and Growth Performance in Post-Weaned Piglets.

This study aimed to investigate effects of long-term probiotic supplementation on gut microbiota and growth performance in health weaned piglets. The non-probiotic group (N-PrB) was fed only a basal diet, while the probiotic group (PrB) was fed a basal diet + probiotic combination (E. faecium 1.6 × 108 CFU/g, B. subtilis 2.0 × 108 CFU/g, S. cerevisiae 3.0 × 108 CFU/g). The probiotics combination was provided to the PrB, mixing with the basal diet in 5 kg/ton. As a result, the PrB exhibited significantly improved weight gain compared to the N-PrB (p = 0.00991). In the gut microbiome analysis, the PrB exhibited a significant increasing tendency of α-diversity compared to those of the N-PrB (p < 0.01). In the bacterial relative abundance changes in bacteria comprising the gut microbiota, Ruminococcaceae (p = 0.00281) and Prevotella (p = 0.00687) tended to significantly increase in the PrB, but decreased in the N-PrB. The Eubaterium coprostanoligenes group exhibited an increasing tendency in both groups, but tended to increase more significantly in the PrB compared to the N-PrB (p = 0.00681). Muribaculaceae tended to significantly increase in the N-PrB, but decreased in the PrB (p = 0.002779). In this study, significant differences on the gut microbiome were found according to the probiotics supplementation in the weaned piglets and these gut microbiome changes appeared to improve the growth performance.

Comparative evaluation of the antihyperglycemic effects of three extracts of sea mustard (Undaria pinnatifida): In vitro and in vivo studies.

Undaria pinnatifida (UP) contains multiple bioactive substances, such as polyphenols, polysaccharides, and amino acids, which are associated with various biological properties. This study aimed to evaluate the antihyperglycemic effects of three extracts obtained from UP. UP was extracted under three different conditions: a low-temperature water extract at 50 °C (UPLW), a high-temperature water extract at 90 °C (UPHW), and a 70 % ethanol extract (UPE). Nontargeted chemical profiling using high-performance liquid chromatography-triple/time-of-flight mass spectrometry (HPLC-Triple TOF-MS/MS) was conducted on the three UP extracts. Subsequently, α-glucosidase inhibitory (AGI) activity, glucose uptake, and the mRNA expression of sodium/glucose cotransporter 1 (SGLT1) and glucose transporter 2 (GLUT2) were evaluated in Caco-2 cell monolayers. Furthermore, an oral carbohydrate tolerance test was performed on C57BL/6 mice. The mice were orally administered UP at 300 mg/kg body weight (B.W.), and the blood glucose level and area under the curve (AUC) were measured. Compared with glucose, UPLW, UPHW and UPE significantly inhibited both glucose uptake and the mRNA expression of SGLT1 and GLUT2 in Caco-2 cell monolayers. After glucose, maltose, and sucrose loading, the blood glucose levels and AUC of the UPLW group were significantly lower than those of the control group. These findings suggest that UPLW has antihyperglycemic effects by regulating glucose uptake through glucose transporters and can be expected to alleviate postprandial hyperglycemia. Therefore, UPLW may have potential as a functional food ingredient for alleviating postprandial hyperglycemia.

Importance of multimodal resident education curriculum for general surgeons: perspectives of trainers and trainees.

PURPOSE: Satisfaction should be prioritized to maximize the value of education for trainees. This study was conducted with professors, fellows, and surgical residents in the Department of general surgery (GS) to evaluate the importance of various educational modules to surgical residents. METHODS: A questionnaire was administered to professors (n = 28), fellows (n = 8), and surgical residents (n = 14), and the responses of the three groups were compared. Four different categories of educational curricula were considered: instructor-led training, clinical education, self-paced learning, and hands-on training. RESULTS: The majority of surgeons regarded attending scrubs as the most important educational module in the training of surgical residents. However, while professors identified assisting operators by participating in surgery as the most important, residents assessed the laparoscopic training module with animal models as the most beneficial. CONCLUSIONS: The best educational training course for surgical residents was hands-on training, which would provide them with several opportunities to operate and perform surgical procedures themselves.

Occurrence of mycotoxins in swine feed from South Korea.

Objectives: To update recent information on contamination levels of mycotoxins in South Korea. Materials and methods: A total of 208 samples sourced from the feeds of swine farms were collected. The contamination levels of mycotoxins, which are aflatoxin (Afla), ochratoxin A (OTA), deoxynivalenol (DON), zearalenone (ZEN), fumonisin (FUM), and T-2 toxin, were investigated by enzyme-linked immunosorbent assays (ELISAs). Results: The detection levels of the total samples were 78.91% for DON, 75.24% for Afla, 47.02% for ZEN, 68.31% for FUM, and 5.94% for OTA and T-2, which were not detected at all. Most of the analyzed mycotoxins showed significant high occurrences in 47.02%-78.91% of the swine feed samples. 11 of the 152 alfa-positive samples exceeded the maximum residue limit (MRL) of Afla proposed by the Korean regulation. In the analysis of mycotoxin detection levels by growth stage, ZEN was found in the nursery stage at a remarkably high concentration level (126.46 ± 63.76 ppb), exceeding the MRL of ZEN for piglets proposed by the European Commission. This mycotoxin was also found in the samples from the gestation barn (89.04 ± 46.05 ppb) and the farrowing house (105.58 ± 94.12) at a high concentration level. Afla was found in the nursery stage at a high concentration (8.00 ± 2.22 ppb), approaching the MRL (10 ppb) of Afla proposed by the Korean regulation. Conclusion: These results indicate that many swine farms in South Korea are still exposed to mycotoxin risk, and special attention and surveillance are necessary for these mycotoxin risks in swine farms.

Why do marionette lines appear? Exploring the anatomical perspectives and role of thread-based interventions.

The pathogenesis of marionette lines involves a complex interplay of anatomical, physiological, and age-related factors leading to the development of wrinkles around the oral commissures. This exploration delves into the distinct anatomical predispositions observed among different ethnicities, emphasizing the role of compact modiolus structures and muscle compositions. Notably, individuals of East Asian descent exhibit inherent facial structures that predispose them to pronounced sagging around the oral commissures during aging. The emergence of distinct facial lines, such as the commissural line and the melolabial fold, contributes to the formation of marionette lines. This specific wrinkle pattern, resembling a marionette puppet's mouth contours, is influenced by various factors like bone resorption, gravitational forces, fat compartment variations, muscle compression, ligament tethering, and skin aging. Treatment strategies for marionette lines encompass diverse interventions, including filler injections, botulinum neurotoxin, surgeries targeting fat reduction, thread lifting, and volumizing fillers. These approaches aim to address the underlying causes and mitigate the appearance of marionette lines. Botulinum neurotoxin injections, for instance, weaken specific facial muscles, reducing downward strain and aiding in tissue retraction. Anatomical considerations during procedures are crucial to avoid nerve or vascular damage. Delicate manipulation and precise entry points are essential to prevent inadvertent injuries, particularly concerning blood vessels like the facial artery and nerves like the mental nerve. Technical guidelines for procedures targeting marionette lines involve specific techniques like cogged thread reverse methods and volumizing thread placements. Attention to entry points, tissue engagement, and the direction of threads is crucial for effective treatment outcomes, minimizing complications, and ensuring patient safety.

SMAS repositioning technique utilizing cog thread: Anatomical perspectives.

INTRODUCTION: Face-lifting surgeries were once common among individuals over 60 years old due to skin laxity, but recent trends favor thread lifting in this age group. Understanding dynamic changes in facial anatomy during postural shifts is essential. METHOD: Fresh cadaver studies have demonstrated the passage of threads through the superficial musculoaponeurotic system (SMAS) layer, confirming the efficacy of the technique. Proper insertion depth targeting SMAS repositioning, rather than superficial skin layers, is crucial. RESULT: The natural movement of tissues secured by thread (N-Cog and N-Fix, N-Finders Inc., Korea) insertion results in lifting effects. However, complications may arise if threads affect deeper facial muscles, leading to discomfort. Fibrous septa play a significant role in guiding thread placement, with different densities influencing thread maneuverability and tissue response during lifting. CONCLUSION: Procedures targeting SMAS repositioning using threads aim to maintain the new position of relocated tissues. Understanding structural variations in facial regions informs thread selection and placement. Aligning threads with tissue movement and the intended SMAS layer positioning is vital to prevent complications. Balancing thread insertion depth and tissue traction is critical for successful outcomes. Modern thread lifting techniques prioritize SMAS repositioning, enhancing lifting effects while ensuring procedure safety and efficacy.

Unveiling Immunomodulatory Effects of Euglena gracilis in Immunosuppressed Mice: Transcriptome and Pathway Analysis.

The immunomodulatory effects of Euglena gracilis (Euglena) and its bioactive component, ß-1,3-glucan (paramylon), have been clarified through various studies. However, the detailed mechanisms of the immune regulation remain to be elucidated. This study was designed not only to investigate the immunomodulatory effects but also to determine the genetic mechanisms of Euglena and ß-glucan in cyclophosphamide (CCP)-induced immunosuppressed mice. The animals were orally administered saline, Euglena (800 mg/kg B.W.) or ß-glucan (400 mg/kg B.W.) for 19 days, and CCP (80 mg/kg B.W.) was subsequently administered to induce immunosuppression in the mice. The mice exhibited significant decreases in body weight, organ weight, and the spleen index. However, there were significant improvements in the spleen weight and the spleen index in CCP-induced mice after the oral administration of Euglena and ß-glucan. Transcriptome analysis of the splenocytes revealed immune-related differentially expressed genes (DEGs) regulated in the Euglena- and ß-glucantreated groups. Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses indicated that pathways related with interleukin (IL)-17 and cAMP play significant roles in regulating T cells, B cells, and inflammatory cytokines. Additionally, Ptgs2, a major inflammatory factor, was exclusively expressed in the Euglena-treated group, suggesting that Euglena's beneficial components, such as carotenoids, could regulate these genes by influencing immune lymphocytes and inflammatory cytokines in CCP-induced mice. This study validated the immunomodulatory effects of Euglena and highlighted its underlying mechanisms, suggesting a positive contribution to the determination of phenotypes associated with immune-related diseases and the research and development of immunotherapies.

Lipolytic agents for submental fat reduction: Review.

RESULT: The review delves into the realm of reducing submental fat, presenting a comprehensive analysis of various lipolytic agents used in plastic surgery and dermatology. The introduction establishes the context by defining the key indicators of a youthful neck and emphasizing the significant influence of fat in the aging process, particularly in the submental area. The usage of aminophylline involves subcutaneous injections, facilitating fat breakdown by increasing cyclic adenosine monophosphate and inhibiting adenosine receptors. Hypotonic pharmacologic lipo-dissolution induces fat dissolution via injected compounds under pressure, while lipolytic lymphatic drainage employs hyaluronidase to reduce tissue viscosity, aiding fat circulation. Glycerophosphorylcholine containing choline alfoscerate claims to activate fat metabolism, whereas the utilization of phosphatidylcholine combined with deoxycholate lacks cosmetic approval due to safety concerns. Deoxycholic acid has FDA approval for submental fat reduction, yet its mechanisms remain incompletely understood. Understanding the complex anatomy and mechanisms of lipolytic agents is essential for safe and effective submental fat reduction, despite evolving practices and off-label utilization. Clinical guidelines and references support this discussion, offering insights for safer applications.
