Background: Hollowness in the anteromedial, buccal, and lateral cheek regions is a common concern in aesthetic medicine, often resulting from age-related volume loss and structural changes. Advanced filler injection techniques that incorporate a thorough understanding of facial anatomy are critical for achieving optimal and safe outcomes.
Objective: To review and detail anatomically guided filler injection techniques for addressing hollowness in specific cheek regions, considering facial anatomy, ethnic variations, and patient-specific aesthetic goals.
Methods: A comprehensive analysis of the layered cheek structure-including skin, fat compartments, muscles, and neurovascular elements-was conducted to define effective injection techniques. Step-by-step procedures using cannula-based filler injections were described, focusing on targeting appropriate tissue planes while avoiding critical structures. Ethnic differences between Western and Asian populations were also considered to provide tailored approaches.
Results: Targeted filler injections in the anteromedial, buccal, and lateral cheek regions were shown to effectively restore volume and contour by addressing hollow areas. Precision in selecting tissue planes and using cannulas minimized complications and optimized outcomes. Ethnic-specific anatomical variations and aesthetic preferences played a significant role in technique modification and treatment planning.
Conclusion: Anatomical-based filler injection techniques offer a precise and safe approach to nonsurgical facial rejuvenation of the cheek. A deep understanding of facial anatomy, combined with consideration of ethnic differences, enhances treatment efficacy. Future advancements, such as integrating imaging technologies and combination therapies, are expected to further refine facial rejuvenation practices.

Lipid imaging mass spectrometry (LIMS) allows for establishing the bidimensional distribution of lipid species within a tissue section. One of the main advantages is the generation of spatial information on lipid species distribution at a spatial (lateral) resolution bordering on single-cell resolution with no need to isolate cells. Thus, LIMS images demonstrate, with a level of detail never described before, that lipid profiles are highly sensitive to cell type and pathophysiological state.

For the first time, our study provides a comprehensive examination of the anti-cancer effects of structural isomers of carene in breast cancer cells, specifically focusing on cell cycle inhibition and the induction of apoptosis. We utilized the hydro-distillation method to extract Piper nigrum seed essential oil (PNS-EO) and identified its bioactive components through gas chromatography-mass spectrometry (GC-MS) analysis. A total of 46 bioactive compounds were isolated via hydro-distillation, identified through GC-MS analysis, and validated by co-injection using GC analysis.

Graph Neural Networks (GNNs) have shown remarkable achievements and have been extensively applied in various downstream tasks, such as node classification and community detection. However, recent studies have demonstrated that GNNs are vulnerable to subtle adversarial perturbations on graphs, including node injection attacks, which negatively affect downstream tasks. Existing node injection attacks have mainly focused on the limited local nodes, neglecting the analysis of the whole graph which restricts the attack's ability.

Background: In China, stroke is the primary cause of adult death and disability. Because of the increased rate of blood vessel reperfusion, it is important to prevent cerebral ischemia-reperfusion injury, in which glutamate (Glu) excitotoxicity plays a critical role. The most important Glu transporter, GLT-1, is essential for the regulation of Glu, which is dependent on Na-K-ATPase (NKA)-induced ion concentration gradient differences.
