Background: Breast morphology is the primary objective indicator for evaluating the outcome of augmentation surgery. Studies have indicated that breast morphology undergoes certain changes during the early postoperative period, which may result in a discrepancy between postoperative outcomes and preoperative design. This study utilized three-dimensional scanning technology and statistical methods to analyze the influencing factors of breast morphology changes, aiming to provide reference for implant selection and preoperative surgical planning.

The adipogenic property of decellularized adipose-derived matrix (DAM) varies widely across reports, making it difficult to make a horizontal comparison between reports and posing challenges for the stable clinical translation of DAM. It is possibly due to differences in donor characteristics, but the exact relationship remains unclear. Despite extensive research on the differences between superficial and deep layers of abdominal subcutaneous fat, a main donor of DAM, little is known about their extracellular matrix (ECM) which is promising in regenerative medicine.

Decellularized adipose matrix (DAM) is considered to be the most potential biological scaffold for soft tissue repair and reconstruction, as it is able to induce the regeneration of adipose tissue in situ in adulthood. But how does this adipose tissue regeneration happen and develop in vivo? Is it the same as the original autologous one? Temporary existence or long-term survival? These are the key questions that will determine the future applications of DAM. In this study, we investigated the composition, structure and biomechanical properties of DAM before implanting it into the subcutaneous back of immunodeficient mice.
View Article and Find Full Text PDFDecellularized adipose-derived matrix (DAM) has emerged as a promising biomaterial for soft tissue reconstruction. However, due to a lack of research on its complex composition, the understanding of the key components in DAM remains limited, leading to inconsistent adipogenic properties and challenges in optimizing preparation methods purposefully. In this study, it is proposed for the first time that DAM comprises two distinct components: hydrophilic (H-DAM) and lipophilic (L-DAM), each with markedly different effects on fat regeneration.

Previous studies have shown that lutein has excellent adipose tissue affinity and antioxidative stress ability, however, the effects of oral lutein on fat transplantation have not yet been studied.
Objectives: We aimed to investigate whether oral lutein could improve fat transplantation retention by regulating oxidative stress, apoptosis, and inflammatory cytokine levels in graft tissues.
Background: For females in puberty, mastectomy caused by pathological gigantomastia usually brings significant psychological problems. Appropriate immediate breast reconstruction method is necessary.
Objectives: The aim of this study is to present a novel method of breast reconstruction that requires neither implants nor donor-site sacrifice.
Cryoinjury mitigation is key in cell cryopreservation. Here, we aimed to assess the effectiveness of nanographene oxide (nano-GO) for improving cryoprotectant agents (CPAs) in human adipose stem cell (hADSC) cryopreservation. For in vitro experiments, nano-GO (5 μg/mL) was added to the CPAs in the control, and passage (P) 2 hADSCs were collected and cryopreserved for around two weeks.

However, in the treatment of middle and upper ureteral calculi, ureteroscopy is difficult to operate owing to the high location of calculi. Thus, how to improve the treatment effect and reduce the stone migration has become the focus in clinical settings.

Methods: A total of 31 eyes were included, 11 with DME that had undergone vitrectomy, 9 with DME but without vitrectomy, and 11 from age-related cataract patients as controls. The concentrations of cytokines including TNF-α, IL-6, IL-8, IP-10, MCP-1, IFN-γ, MIP-1 α, MIP-1 β, PECAM-1, MIF, VCAM-1, ICAM-1, PIGF were quantified using Luminex Human Discovery Assay.
Aim: To evaluate the effectiveness and safety of intravitreal ranibizumab (IVR) for diabetic macular edema (DME) in vitrectomized versus non-vitrectomized eyes.
Methods: The PubMed, EMBASE, Web of Science, Cochrane, EBSCO were comprehensively searched for studies comparing vitrectomized and non-vitrectomized eyes with DME. Clinical outcomes of best-corrected visual acuity (BCVA), central macular thickness (CMT), the mean number of intravitreal injection and adverse events were extracted and analyzed.
Decellularized Adipose-Derived Matrix (DAM) has the function of inducing adipogenesis, but the distribution of adipogenesis is uneven. We found for the first time that DAM contains two structural components: The tough fibers DAM (T-DAM) and the fine fibers DAM (F-DAM). T-DAM was a dense vortex structure composed of a large number of coarse fibers, characterized by myoblast-related proteins, which cannot achieve fat regeneration and forms a typical "adipose-free zone".

Background: Ischemic necrosis in the distal portion of a flap is a challenging complication in plastic surgery. The authors hypothesized that a novel hybrid flap preconditioning (HFP) device combining foam-mediated external suction and nonsurgical delay can promote skin flap survival better than surgical delay.
Method: Twenty-eight mice were divided into 4 groups: a control group, in which a 4 × 1.
Background: Decellularized adipose-derived matrix (DAM) represents a new alternative to tissue fillers. The function of DAM is closely associated with the decellularization technique used for its preparation. However, most techniques are time-consuming and expensive, and this might reduce the popularity of DAM.

Auxin serves as an essential regulator of the expression of many different genes in plants, thereby regulating growth and development. The specific functional roles of members of the SAUR (small auxin-up RNA) auxin early response gene family in the development of cucumber plants, however, remain to be fully clarified. Here, 62 SAUR family genes were identified, followed by their classification into 7 groups that included several functionally associated cis-regulatory elements.

Background: Breast augmentation patients are often unaware of their preexisting breast asymmetry before surgery but discover it afterward, which leads to postoperative dissatisfaction and increases the reoperation rate. However, elaboration on how patients subjectively analyze breast asymmetry and the recognition thresholds were limited.
Methods: Two hundred female participants, including 100 patients 6 months postoperatively for primary augmentation mammaplasty and 100 preoperative patients, were recruited as two study groups.
