Achieving the Attractive Asian Midface Profile with Hyaluronic Acid-Based Fillers.

Despite different ethnic origins among Asians, midface enhancement is the most frequent noninvasive procedure for hyaluronic acid injection either as a stand-alone treatment or as part of the pan-facial beautification strategy. Because Asians often have an aesthetically undesirable wide, flat, and short face, improving the projection of midface and midline facial structures is an indispensable aesthetic procedure in creating a smaller facial appearance with better three-dimensionality. Achieving an oval facial shape together with increased facial height is also required in most circumstances for a natural and balanced result.

Avoided Level Crossing and Entangled States of Interacting Hydrogen Molecules Detected by the Quantum Superposition Microscope.

Pump-probe measurements by ultrashort THz pulses can be used to excite and follow the coherence dynamics in the time domain of single hydrogen molecules (H) in the junction of a scanning tunneling microscope (STM). By tailoring the resonance frequency through the sample bias, we identified two spectral signatures of the interactions among multiple H molecules. First, the avoided level crossing featured by energy gaps ranging from 20 to 80 GHz was observed because of the level repulsion between two H molecules.

Genome-Wide DNA Methylation Profiling as Frontline Diagnostics for Central Nervous System Embryonal Tumors in Hong Kong.

This paper examines the link between CNS tumor biology and heterogeneity and the use of genome-wide DNA methylation profiling as a clinical diagnostic platform. CNS tumors are the most common solid tumors in children, and their prognosis remains poor. This study retrospectively analyzed pediatric patients with CNS embryonal tumors in Hong Kong between 1999 and 2017, using data from the territory-wide registry and available formalin-fixed paraffin-embedded tumor tissue.

Addressing the Real-World Challenges of Immunoresistance to Botulinum Neurotoxin A in Aesthetic Practice: Insights and Recommendations from a Panel Discussion in Hong Kong.

With increasing off-label aesthetic indications using higher botulinum neurotoxin A (BoNT-A) doses and individuals starting treatment at a younger age, particularly in Asia, there is a greater risk of developing immunoresistance to BoNT-A. This warrants more in-depth discussions by aesthetic practitioners to inform patients and guide shared decision-making. A panel comprising international experts and experienced aesthetic practitioners in Hong Kong discussed the implications and impact of immunoresistance to BoNT-A in contemporary aesthetic practice, along with practical strategies for risk management.

Measuring acute effects of subanesthetic ketamine on cerebrovascular hemodynamics in humans using TD-fNIRS.

AxonQuantifier: A semi-automated program for quantifying axonal density from whole-mounted optic nerves.

Background: Here, we present a semi-automated method for quantifying retinal ganglion cell (RGC) axon density at different distances from the optic nerve crush site using longitudinal, confocal microscopy images taken from whole-mounted optic nerves. This method employs the algorithm AxonQuantifier which operates on the freely available program, ImageJ.

New Method: To validate this method, seven adult male Long Evans rats underwent optic nerve crush injury followed by in vivo treatment with electric fields of varying strengths for 30 days to produce optic nerves with a wide range of axon densities distal to the optic nerve crush site.

Deconstructing the role of MALAT1 in MAPK-signaling in melanoma: insights from antisense oligonucleotide treatment.

The long non-coding RNA (lncRNA) MALAT1 is a regulator of oncogenesis and cancer progression. MAPK-pathway upregulation is the main event in the development and progression of human cancer, including melanoma and recent studies have shown that MALAT1 has a significant impact on the regulation of gene and protein expression in the MAPK pathway. However, the role of MALAT1 in regulation of gene and protein expression of the MAPK-pathway kinases RAS, RAF, MEK and ERK in melanoma is largely unknown.

Outcomes in patients with acute stroke treated at a comprehensive stroke center using telemedicine versus in-person assessments.

Introduction: Telemedicine has been shown to be a safe and effective modality to assess and treat patients with acute stroke who present to a community hospital. There are no previous reports on using telemedicine to treat patients with acute stroke who present to a comprehensive stroke center. We report here the outcomes of patients with acute stroke treated in 2021 at our comprehensive stroke center using telemedicine versus an in-person assessment.

Lysine-Derived Charge-Altering Releasable Transporters: Targeted Delivery of mRNA and siRNA to the Lungs.

Targeted delivery of nucleic acid therapeutics to the lungs could transform treatment options for pulmonary disease. We have previously developed oligomeric charge-altering releasable transporters (CARTs) for in vivo mRNA transfection and demonstrated their efficacy for use in mRNA-based cancer vaccination and local immunomodulatory therapies against murine tumors. While our previously reported glycine-based CART-mRNA complexes (mRNA) show selective protein expression in the spleen (mouse, >99%), here, we report a new lysine-derived CART-mRNA complex mRNA that, without additives or targeting ligands, shows selective protein expression in the lungs (mouse, >90%) following systemic IV administration.

Assessing "Spin" in Urology Randomized Controlled Trials With Statistically Nonsignificant Primary Outcomes.

Purpose: "Spin" refers to a form of language manipulation that positively reflects negative findings or downplays potential harms. Spin has been reported in randomized controlled trials of other surgical specialties, which can lead to the recommendation of subpar or ineffective treatments. The goal of this study was to characterize spin strategies and severity in statistically nonsignificant urology randomized controlled trials.

Facial Beautification and Rejuvenation with Injectables: My Preferred Approach.

Asians are of different ethnic origins. Nevertheless, they share the common facial structural deficiencies and consequences of the aging process that create the opportunity for esthetic intervention. As a result, Injectables are widely used in young Asians to achieve an oval facial shape with increased facial height and projection.

Melanoma risk during immunomodulating treatment.

Immunosuppressive therapy is standard for the treatment of inflammatory diseases and for minimizing rejection in transplant patients. However, immunosuppressant drugs are associated with an increased risk of certain cancers. In particular, melanoma is an immunogenic tumor and as such, is strongly influenced by the immune system.
