Singular entry point technique for forehead and temple filler augmentation: Anatomical and clinical perspectives.

Background: The depressed volume of the forehead and temple is resolved by filler injection. However, the current method has the potential to cause pain and side effects in patients, depending on the skill of the clinician. Therefore, this study proposes a new method for safer and simpler injection using only one injection entry point.

An innovative microcoring technology: A novel approach to acne scar treatment.

Background: Acne scars present a complex challenge in dermatology and cosmetics, despite advancements in technological interventions such as fractional lasers, microneedling, and surgical procedures. Effective treatment remains elusive for many individuals.

Objective: This study aims to evaluate the efficacy of rotational fractional resection using 1 mm diameter rotating scalpels as a primary treatment for icepick and boxcar scars on the cheeks and glabella region.

Intramuscular Neural Distribution of Adductor Pollicis Muscle Spasticity in Cadaver Model Regarding Botulinum Neurotoxin Treatment.

Purpose: The adductor pollicis muscle is frequently targeted for botulinum neurotoxin injective treatment for spasticity. However, there are no injective guidelines for delivering injection to the muscle.

Materials And Methods: A method known as the modified Sihler's method was used to stain the adductor pollicis muscle in 16 specimens to reveal intramuscular neural distribution of the muscle.

Novel Clinical Anatomical Consideration of the Superficial and Deep Layers of the Deep Temporal Fascia.

Background: The deep temporal fascia provides anchoring during thread lifting, which is a minimally invasive face-lifting procedure. However, anatomical studies involving the deep temporal fascia in addition to effective and safe thread-lifting procedures are scarce. The authors clarified the anatomy of the superficial layer of the deep temporal fascia and its surrounding structure using ultrasonography, histologic sections, and cadaveric dissection to propose an effective thread-lifting procedure guideline.

Anatomical proposal for hyaluronic acid filler injection in subzygomatic arch depression: A dual-plane injection technique.

A subzygomatic arch depression creates a bulky face outline. To smoothen these depressions and correct facial contours, hyaluronic acid filler injection methods are frequently used. However, the complexity of the subzygomatic region make it difficult for practitioners to effectively volume the region.

Anatomical Continuation Between the Sub-Superficial Musculoaponeurotic System Fat and Retro-Orbicularis Oculi Fat: The True Nature of the Retro-Orbicularis Oculi Fat.

This study aims to analyze the anatomical location and continuation between the retro-orbicularis oculi fat (ROOF) and sub-superficial musculoaponeurotic system fat (subSMAS fat; named "innominate fascia") by comparing their layered structures, thereby letting us suggest a safe minimally invasive procedure guideline for the forehead and temple. Ultrasonographic scanning was performed from the upper medial eyebrow to the lateral side of the superior temporal line in 109 volunteers. Hematoxylin and eosin staining was performed on five specimens at the same area as ultrasonographic scanning.

The attenuating effects of pyridoxamine on adipocyte hypertrophy and inflammation differ by adipocyte location.

It is known that receptor for advanced glycation end products (RAGE) and its ligands accumulate in the fat tissues of obese individuals, and RAGE ligands induce M1 macrophage polarization, which in turn induces inflammation. We evaluated the effect of pyridoxamine on RAGE ligand accumulation and M1 polarization in the visceral, subcutaneous, and perivascular fat tissues of Sprague-Dawley rats fed a high fat diet (HFD). Pyridoxamine reduced HFD-induced weight gain, attenuated adipocyte size increases, RAGE ligand accumulations, RAGE-RAGE ligands binding, decreased macrophage M1 polarization and increased M2 polarization in visceral fat tissues, but not in subcutaneous tissues.

Parry-Romberg Syndrome Augmented by Hyaluronic Acid Filler.

Parry Romberg Syndrome (PRS), also known as idiopathic progressive hemifacial atrophy, is a rare neurocutaneous disorder characterized by loss of skin and subcutaneous fat of face, muscles, and bones causing unilateral atrophy. Most patients require only soft tissue augmentation although syndrome has varying grades of severity. In the majority of reported cases, it has been treated with surgical flap or autologous fat transplantation.

Advanced glycation end-product (AGE)-albumin from activated macrophage is critical in human mesenchymal stem cells survival and post-ischemic reperfusion injury.

Post-ischemic reperfusion injury (PIRI) triggers an intense inflammatory response which is essential for repair but is also implicated in pathogenesis of post-ischemic remodeling in several organs in human. Stem cell therapy has recently emerged as a promising method for treatment of PIRI in human. However, satisfactory results have not been reported due to severe loss of injected stem cells in PIRI including critical limb ischemia (CLI).

Protection against RAGE-mediated neuronal cell death by sRAGE-secreting human mesenchymal stem cells in 5xFAD transgenic mouse model.

Alzheimer's disease (AD), which is the most commonly encountered neurodegenerative disease, causes synaptic dysfunction and neuronal loss due to various pathological processes that include tau abnormality and amyloid beta (Aβ) accumulation. Aβ stimulates the secretion and the synthesis of Receptor for Advanced Glycation End products (RAGE) ligand by activating microglial cells, and has been reported to cause neuronal cell death in Aβ treated rats and in mice with neurotoxin-induced Parkinson's disease. The soluble form of RAGE (sRAGE) is known to reduce inflammation, and to decrease microglial cell activation and Aβ deposition, and thus, it protects from neuronal cell death in AD.

Age dependent accumulation patterns of advanced glycation end product receptor (RAGE) ligands and binding intensities between RAGE and its ligands differ in the liver, kidney, and skeletal muscle.

Background: Much evidence indicates receptor for advanced glycation end products (RAGE) related inflammation play essential roles during aging. However, the majority of studies have focused on advanced glycation end products (AGEs) and not on other RAGE ligands. In the present study, the authors evaluated whether the accumulation of RAGE ligands and binding intensities between RAGE and its ligands differ in kidney, liver, and skeletal muscle during aging.

Age-related accumulation of advanced glycation end-products-albumin, S100β, and the expressions of advanced glycation end product receptor differ in visceral and subcutaneous fat.

Visceral fat induces more inflammation by activating macrophages than subcutaneous fat, and inflammation is an underlying feature of the pathogeneses of various diseases, including cardiovascular disease and diabetes. Advanced glycation end products (AGEs), S100β, and their receptors, the receptor for advanced glycation end products (RAGE), lead to macrophage activation. However, little information is available regarding the differential accumulations of AGE-albumin (serum albumin modified by AGEs), S100β, or expressions of RAGE in different adipocyte types in fat tissues.

Administration of clomipramine to neonatal mice alters stress response behavior and serotonergic gene expressions in adult mice.

Early life exposure to antidepressants frequently occurs when pregnant mothers take the medication during late pregnancy. Previous studies in animal models have shown that early exposure to certain antidepressants can alter some behaviors in adulthood. We examined whether the administration of clomipramine, a serotonin reuptake inhibitor, to neonatal mice could result in depression-related behavioral alterations in adult mice.
