Alloplastic facial implants and injectable fillers are currently used for facial rejuvenation and augmentation. Their respective roles in augmentation and volume replacement of the chin and midface are discussed. Treatment goals, patient selection, procedures, and patient recovery are detailed. In addition, there is a segment for surgeons presenting a decision algorithm for selecting surgical versus less-invasive or nonsurgical approaches for midface rejuvenation.

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.
Objective: Non-surgical facial aesthetics (NSFA) is a rapidly growing field involving the use of dermal fillers and botulinum toxin for aesthetic enhancement. The aesthetic injectables market is expanding, attracting interest from individuals seeking NSFA procedures. There has also been marked interest among healthcare professionals (HCPs) aspiring to become aesthetic practitioners.

In this work, six bovine bone gelatin (type B) samples with varying molecular weight (MW) fractions, comprising α-chains, high- and low-MW fractions, were prepared using ethanol precipitation and pH adjustment. The influence of molecular weight distribution (MWD) on gelatin gel strength was examined, along with the effects of these different MW fractions on microbial transglutaminase (MTGase) cross-linking gelatin. The results showed that, without MTGase treatment, high-MW fractions acted as key fillers in the formation of gelatin gel networks, while α-chains and their aggregates played a central role.

Sulfur autotrophic denitrification (SAD) is a promising technology for nitrogen removal, particularly suitable for low carbon-to-nitrogen wastewater without additional carbon sources. However, SAD inevitably generates significant amounts of SO. To address this issue, combining SAD with iron-carbon micro-electrolysis technology, which can reduce sulfate, provides electron donors for autotrophic denitrification and facilitates sulfur cycling.

Moving bed biofilm reactors can purify urban domestic sewage through microbial biodegradation. High-throughput sequencing was used to study the response mechanism of the biofilm microbial community to temperature. The effluent quality of the reactor declined with the decrease in temperature.
