Objective: To observe the clinical effect of ceramic on ceramic total hip arthroplasty(THA)in Crowe IV developmental dysplasia of the hip(DDH).
Methods: From April 2008 to December 2015, 137 hips of 111 Crowe IV DDH patients received THA using Forte or Delta ceramic on ceramic by one senior surgeon, which consists of 85 unilateral hips and 26 bilateral hips. The average age of the patients was(38.88±10.83) years old ranging from 18 to 68 years old. The mean follow-up was(41.16±21.50) months ranging from 12 to 96 months. All the patients were evaluated by Harris Hip Score. Radiographic evaluations were made preoperatively and during follow-up. Harris scores, the incidence of complications such as ceramic fracture, squeaking, dislocation were observed.
Results: The mean preoperative Harris score was 56.54±15.67, the mean postoperative Harris score was 88.30±6.86(=0.017). Periprosthetic osteolysis was not deteced around any cup. No ceramic fracture occurred. There were 3 cases of revision surgery due to infection, losening of the stem and limb length discrepancy, respectively; 3 cases of dislocation occurred. Seventy-seven patients were recorded the gait and the hip mobility, the hip flexion of 69 patients were above 120 degrees.
Conclusions: Ceramic on ceramic bearing showed an encouraging result in Crowe IV DDH total hip arthroplasty.

Background: The subcellular localization of mRNA plays a crucial role in gene expression regulation and various cellular processes. However, existing wet lab techniques like RNA-FISH are usually time-consuming, labor-intensive, and limited to specific tissue types. Researchers have developed several computational methods to predict mRNA subcellular localization to address this.

The development of affordable ceramic membranes is essential for reducing expenses and optimizing the treatment of oily wastewater. There is an urgent demand for membranes that are not only affordable and easy to operate but also stable and capable of managing high fluxes to address the increasing volumes of oily wastewater. The significant production demands associated with many commercially available ceramic membranes, primarily due to the use of specialised raw materials and intricate processing methods, limiting their suitability for many wastewater treatment applications.

Developing highly active and durable non-noble metal catalysts is crucial for energy conversion and storage, especially for proton exchange membrane fuel cells (PEMFCs) and lithium-oxygen (Li-O) batteries. Non-noble metal catalysts are considered the greatest potential candidates to replace noble metal catalysts in PEMFCs and Li-O batteries. Herein, we propose a novel type of non-noble metal catalyst (Fe-Hf/N/C) doped with Hf into a mesoporous carbon material derived from Hf-ZIF-8 and co-doping with Fe and N, which greatly enhanced the activity and durability of the catalyst.

Bacterial infections are a common cause of clinical complications associated with the use of orthodontic microimplants. Biofilm formation on their surfaces and subsequent infection of peri-implant tissues can result in either exfoliation or surgical removal of these medical devices. In order to improve the properties of microimplants, hybrid coatings enriched with silver nanoparticles, calcium, and phosphorus were investigated.
