Introduction: The treatment of breast ptosis using mastopexy associated with the inclusion of a silicone prosthesis in a single surgical procedure is a challenge for surgeons. The aim of this study is to describe the 15-year experience with the placement of silicone breast implants in double, subfascial and submuscular space, in the treatment of patients with breast ptosis, and to analyze the aesthetic results of patients who underwent such surgeries.
Method: During the 15-year period, between 2005 and 2020, 640 mastopexies were performed with the inclusion of silicone breast implants in double space, with high-profile round polyurethane prostheses whose volumes ranged from 135 to 435 ml, in patients with grade 2 and 3 breast ptosis.
Results: The age of the patients ranged from 18 to 55 years and the average age was 34 years. The postoperative follow-up time was 18 months. 400 patients (62.5%) had grade II ptosis, whereas 240 of them (37.5%) had grade III ptosis. The main complications were: 19 cases (3%) of residual sagging skin, 19 cases (3%) of unsightly scars, 12 cases (2%) of partial areola necrosis. There was no case of infection or seroma. There were 330 primary surgeries (52%) and 310 secondary surgeries (48%).
Conclusion: After 15 years of performing mastopexy with prosthesis in double space, both in primary and secondary surgeries, it can be concluded that the technique reached its maturity providing good long-term results with the maintenance of the projection of the upper pole of the breast and low recurrence of ptosis in the lower pole and low rate of complications.

Introduction: The healthy aging of older adults in dual-older adult communities is influenced by multiple factors, and understanding its underlying mechanisms can promote healthy aging among the older adults in a wide range of developing countries. This comprehensive study delves into the intricate interplay between multifaceted built environmental factors, and their direct and indirect effects on the successful AIP residing in double-aging neighborhoods.
Methods: Applying a series of HLM, the research meticulously explores the intricate links between SAIP and multi-scale aging spaces, including home space, community social participation, and built environments.

Background: The high-frequency induction rate of haploid is crucial for double haploid (DH) breeding. The combination of multiple haploid-induced genes, such as ZmPLA1/MATL/NLD and ZmDMP, can synergistically enhance the haploid induction rate (HIR) in maize. However, the potential synergistic effects between OsMATL and OsDMP genes in rice remain unclear.

The microbial aminotransferase enzyme DapC is vital for lysine biosynthesis in various Gram-positive bacteria, including . Characterization of the enzyme's conformational dynamics and identifying the key residues for ligand binding are crucial for the development of effective antimicrobials. This study employs atomistic simulations to explore and categorize the dynamics of DapC in comparison to other classes of aminotransferase.

Seawater electrolysis has emerged as a promising approach for the generation of hydrogen energy, but the production of deleterious chlorine derivatives (e.g., chloride and hypochlorite) presents a significant challenge due to the severe corrosion at the anode.

We report spectroscopic and spectrometric experiments that probe the London dispersion interaction between -butyl substituents in three series of covalently linked, protonated -pyridines in the gas phase. Molecular ions in the three test series, along with several reference molecules for control, were electrosprayed from solution into the gas phase and then probed by infrared multiphoton dissociation spectroscopy and trapped ion mobility spectrometry. The observed N-H stretching frequencies provided an experimental readout diagnostic of the ground-state geometry of each ion, which could be furthermore compared to a second, independent structural readout via the collision cross section.
