The Application of Three-dimensional Measurement and Grayscale Value Measurement Techniques in Lower Eyelid Blepharoplasty.

Background: Lower eyelid blepharoplasty addresses under-eye bags and tear troughs, but traditional evaluations lack objectivity. 3D imaging and grayscale analysis offer a novel, quantitative approach.

Objectives: To objectively assess blepharoplasty outcomes using 3D imaging and grayscale analysis, validating their effectiveness in capturing morphological and skin texture changes.

Bioactive oligopeptides and the application in skin regeneration and rejuvenation.

Oligopeptides, composed of 2-10 amino acid residues, are protein fragments with unique structural characteristics, including small molecular size, high biocompatibility, and modifiable functional groups. These features endow oligopeptides with excellent permeability, safety, and versatile biological activities, making them widely applicable in disease treatment, drug delivery, and skincare. In particular, oligopeptides have emerged as advanced ingredients in skincare, offering anti-aging, anti-wrinkle, and whitening effects by regulating key biological processes such as collagen synthesis, antioxidant defense, and melanin production.

Application of Orbital Septal Fat Repositioning Combined With SVF-Gel Fillers in Lower Blepharoplasty.

Background: Lower blepharoplasty is a widely used cosmetic surgical procedure to improve under-eye bags and tear trough deformities, aiming to enhance facial aesthetics and achieve a more youthful appearance. The formation of these deformities is often associated with factors such as aging, skin laxity, and fat displacement. Traditional surgical methods include orbital septal fat repositioning and fat grafting, each with its own advantages and limitations.

Palmitoyl-carnitine Regulates Lung Development by Promoting Pulmonary Mesenchyme Proliferation.

Disruption of acylcarnitine homeostasis results in life-threatening outcomes in humans. Carnitine-acylcarnitine translocase deficiency (CACTD) is a scarce autosomal recessive genetic disease and may result in patients' death due to heart arrest or respiratory insufficiency. However, the reasons and mechanism of CACTD inducing respiratory insufficiency have never been elucidated.

Application of Wide, Adjustable External Traction Fixation in Conjunctival Approach Orbital Fat Reposition Surgery.

Background: The correction of tear trough deformities is a significant challenge. The aim of this study is to present a new technique of using wide, adjustable external traction fixation in conjunctival approach orbital fat reposition surgery.

Methods: This is a retrospective case series study conducted on 69 patients, aged 18 to 45 years, who underwent surgery for palpebral bags and tear trough deformities (TTD) between October 2022 and March 2024.

Three-dimensional Stereoscopic Evaluation and Quantitative Gray Scale Assessment of the Nasolabial Fold and Its Application in Injection Therapy.

With the growing demand for aesthetic enhancements, particularly filler injections for nasolabial folds (NLFs), there is a need for more objective and quantitative assessment methods beyond the traditional subjective scales like the Wrinkle Severity Rating Scale (WSRS). This study introduces a novel evaluation method combining 3-dimensional (3D) imaging and grayscale analysis to objectively assess NLF severity and treatment outcomes. A total of 100 healthy participants (86 females, 14 males; mean age 41.

A New Method of Orbital Septal Fat Flap in Transconjunctival Approach.

Background: Orbital fat release is critical in blepharoplasty for correcting tear trough deformities, but traditional transconjunctival approaches often face limitations due to restricted fat volume and pedicle length. This study introduces an innovative technique by reconstructing the orbital fat flap, aiming to improve tear trough coverage and optimize Aesthet outcomes.

Methods: The technique is achieved by reconstructing the orbital fat flap.

The Application of Reverse Z-Plasty Design in Medial Canthal Skin Redundancy Reconstruction Surgery.

Purpose: To investigate the clinical outcomes of reverse Z-plasty in the reconstruction of epicanthal fold.

Methods: We conducted a retrospective analysis on clinical data from patients who underwent medial canthal skin redundancy reconstruction surgery from September 2019 to January 2023. The surgical procedure involved a preoperative design for the incision line, suborbicularis oculi dissection to create a muscle flap, and the use of a reverse Z-flap for the reconstruction of the lateral canthal fold.

Patient-Specific Implants for Correction of Midfacial Aging.

The nasolabial folds (NLFs) may be shallowed with the use of nostril base augmentation. This study aimed to design and customize patient-specific implants (PSIs) with computer-aided design/computer-aided manufacturing (CAD/CAM) to correct NLF deepening caused by midfacial aging. The patient's head computed tomography data obtained and were used for reconstruction.

Use of liquid concentrated growth factor in the management of necrotic tissue after facial vascular complications induced by hyaluronic acid injection.

Introduction: HA fillers may induce facial vascular embolism. The resulting tissue ischemia and necrosis are severe iatrogenic complications for which no effective treatments are available.

Objective: This single-center case series studied the use of liquid CGF in the management of facial tissue necrosis due to HA injection.

Seasonal skin darkening in Chinese women: the Shanghaiese experience of daily sun protection.

The facial skin tone of two groups of Chinese women from Shanghai was compared using standard colorimetric space techniques during a 6-month interval between January and July 2011. During the study period, one group of women (n = 40) applied a potent sun-protective cosmetic product daily, while the other group (n = 40) did not use any sun protection. The results, based on images taken using a standardized digital camera coupled to a spectroradiometer, showed that sun protection largely mitigated changes in the components of skin tone, ie, lightness, melanization, and individual typology angle parameters.

Effect of human mesenchymal stem cells on the growth of HepG2 and Hela cells.

Human mesenchymal stem cells (hMSCs) accumulate at carcinomas and have a great impact on cancer cell's behavior. Here we demonstrated that hMSCs could display both the promotional and inhibitive effects on growth of HepG2 and Hela cells by using the conditioned media, indirect co-culture, and cell-to-cell co-culture. Cell growth was increased following the addition of lower proportion of hMSCs while decreased by treatment of higher proportion of hMSCs.

Nano-LC-MS/MS based proteomics of hepatocellular carcinoma cells compared to Chang liver cells and tanshinone IIA induction.

Human hepatocellular carcinoma (HCC) is one of the most malignant tumors, being particularly induced by unregulated growth and metastasis, and is a leading cause of death and major health problems in many countries. We report here the identification of 167 differentially expressed proteins between HCC (MHCC97-H) cells and Chang liver cells using enhanced nano-liquid chromatography/mass spectrometry (LC/MS). The most relevant pathways of differentially expressed proteins are involved in cytoskeleton organization, stress defense, and energy homeostasis etc.

Metabolomic profiles delineate potential roles for gadolinium chloride in the proliferation or inhibition of Hela cells.

Lanthanides (Lns) compounds have been reported to possess contrary effects on cell activity, i.e., promoting cell cycle progression and cell growth by lower concentration treatment, but suppressing cell proliferation and inducing cell apoptosis at higher dosing.

SigN is responsible for differentiation and stress responses based on comparative proteomic analyses of Streptomyces coelicolor wild-type and sigN deletion strains.

To address the functions of SigN (SCO4034) in Streptomyces coelicolor, we constructed a sigN null mutant M145Z, which showed a defect in sporulation. The differential proteomic profiles of wild-type S. coelicolors M145 and M145Z were demonstrated by two-dimensional polyacrylamide gel electrophoresis (2D PAGE), which identified 24 different spots that were up- or down-regulated due to sigN disruption.
