Background: Postradiotherapy nasopharyngeal necrosis with granulation mass (PRNN-GM) is a rare subtype of postradiotherapy nasopharyngeal necrosis (PRNN). It is characterized by the formation of isolated granulomatous tissue masses or masses combined with PRNN. However, the relationship between clinical features and survival outcomes in PRNN-GM remains unclear.

Introduction: Wound healing is a complex process involving multiple stages, including inflammation, proliferation, and remodeling. Effective wound management strategies are essential for accelerating healing and improving outcomes. The CELLADEEP patch, incorporating iontophoresis therapy and microneedle technology, was evaluated for its potential to enhance the wound healing process.

However, the above process was prone to sludge floating during high load operation and thereby affecting the efficient and stable operation of the system. Excessive production of extracellular polymeric substance (EPS) was considered to be the main reason for anaerobic granular sludge flotation, but the summaries in this area were not comprehensive enough.

Despite the fact that the estimated prevalence of RLS among HD patients is widely reported, these results varied significantly in the relevant literature. Due to this limitation, the aim of this study was to determine the global prevalence of RLS among HD patients.
View Article and Find Full Text PDFThe regulation of proinflammatory mediators has been explored to promote natural healing without abnormal inflammation or autoimmune response induced by their overproduction. However, most efforts to control these mediators have relied on pharmacological substances that are directly engaged in biological cycles. It is believed that functional porous materials removing target mediators provide a new way to promote the healing process using their adsorption mechanisms.

In both mouse and human skin models, a novel collagen stimulation was compared with hyaluronic acid filler.
Materials And Methods: An electron microscope was used to capture images of the solid particle microsphere shape.
Background/aim: Chitosan-based functional materials have attracted considerable attention worldwide for applications in wound healing, especially in skin wound healing, due to their efficiency in hemostasis, anti-bacterial, and skin regeneration. Various chitosan-based products have been developed for skin wound healing applications, but most of these face limitations in either efficacy or cost-effectiveness. Therefore, there is a need to develop a unique material that can handle all of these concerns and be utilized for acute and chronic wounds.

However, capsular contracture is a severe complication caused by the insertion of breast implants, which can endanger the health of patients. In this study, twelve different silicone breast implants were tested to determine which could lead to a lower incidence of capsular contracture.

Materials And Methods: A tranilast-loaded microneedle (TMN) was developed and applied in a rabbit ear model to treat an induced HS.
Objective: To evaluate the feasibility and efficacy in selected T4a glottic cancer (thyroid cartilage invasion adherence to the anterior commissure) treated with frontolateral vertical partial laryngectomy (FLVPL) and laryngeal framework reconstruction using titanium mesh.
Methods: Six patients with the limited T4a glottic cancer with thyroid cartilage destruction adherence to the anterior commissure, underwent FLVPL from 2009 to 2016 in Sun Yat-Sen University Cancer Center. All patients were followed up postoperatively.
Background/aim: The skin plays an important role in protecting the body from mechanical damage, microbial infection, ultraviolet radiation, and extreme temperatures. Many products as well as ongoing studies have focused on skin injury and repair; however, unlimited challenges are still being faced. Furthermore, the drugs that are currently on the market are not adequate to meet the increasing medical needs.
View Article and Find Full Text PDFAnaplastic large cell lymphoma (ALCL) is an uncommon type of non-Hodgkin's lymphoma (NHL), as well as one of the subtypes of T cell lymphoma, accounting for 1 to 3% of non-Hodgkin's lymphomas and around 15% of T cell lymphomas. In 2016, the World Health Organization (WHO) classified anaplastic large cell lymphoma into four categories: ALK-positive ALCL (ALK+ALCL), ALK-negative ALCL (ALK-ALCL), primary cutaneous ALCL (pcALCL), and breast-implant-associated ALCL (BIA-ALCL), respectively. Clinical symptoms, gene changes, prognoses, and therapy differ among the four types.

A combination of a hydrocolloid and nanoparticles (NPs), such as gold (Au), improves the wound healing rate, but Au-NPs are expensive and unable to block ultraviolet (UV) light. Herein, we combined zinc oxide nanoparticles (ZnO-NPs) with hydrocolloids for a less expensive and more effective UV-blocking treatment of wounds.

In this study, the content of five heavy metals(Pb, Cd, As, Hg, and Cu) in 59 batches of Lonicerae Japonicae Flos(LJF) medicinal materials and pieces were determined by inductively coupled plasma mass spectrometry(ICP-MS). The health risk assessment was processed using the maximum estimated daily intake(EDI), target hazard quotients(THQ), and carcinogenic risks(CR) assessment models. With reference to the limit standard for heavy metal content in LJF specified in 2020 edition of Chinese Pharmacopoeia, five batches produced in Hebei were found to contain excessive Pb, and the remaining 54 batches met the specifications, with the unqualified rate of 8.

Materials And Methods: The nucleic acid content (residual double-stranded DNA) and the levels of the remaining growth factors after decellularization were measured for each ADM.
Cosmetic silicone implants for breast reconstruction often lead to medical complications, such as abnormally excessive fibrosis driven by foreign body granulomatous inflammation. The purpose of this study was to develop a silicone breast implant capable of local and controlled release of a glucocorticoid drug triamcinolone acetonide (TA) for the prevention of silicone-breast-implant-induced fibrosis in a Yorkshire pig model (in vivo). Implants were dip-coated in a TA solution to load 1.
