Case report: A rare case of desmoid-type fibromatosis originating in the small intestine

BackgroundDesmoid-type fibromatosis (DF) is characterized by a rare monoclonal fibroblast proliferation that exhibits variable and unpredictable clinical presentation. DF can be classified into sporadic and hereditary types. Despite extensive research efforts, the exact etiology of DF remains elusive.Case descriptionA 31-year-old male patient presented to the hospital with a progressively growing mass in the right lower abdomen, accompanied by abdominal discomfort. Symptoms are discovered 1 week before admission. Enteroscopy revealed no evidence of colonic abnormalities, and blood tests did not indicate any abnormalities. Due to the indeterminate nature of the mass during surgery, a partial resection of the ileum and cecum was performed, followed by ileocolonic end-to-end anastomosis, with no postoperative complications. The final pathological diagnosis confirmed primary desmoid-type fibromatosis of the distal ileum (invasive fibromatosis). To effectively manage DF, we recommend a follow-up schedule for patients. This includes appointments every 3 months in the first year following surgery, followed by appointments every 6 months up to the fifth year, and then once a year thereafter. The follow-up examinations should include collection of the patient’s medical history, physical examination, blood tests, ultrasounds, CT scans, and other relevant assessments. During the first year of the follow-up period, no further treatment was administered, and the patient remained disease-free.ConclusionDesmoid-type fibromatosis (DF) originating from the small intestine is an extremely rare condition that exhibits local invasiveness and can be life-threatening. Despite its benign histology, DF has a high local recurrence rate and lacks metastatic potential. Diagnosis of DF remains challenging, especially in cases where surgical intervention is not feasible due to asymptomatic patients or partial organ impairment. In such cases, a “watchful waiting” approach is recommended as the initial treatment strategy. However, when preoperative diagnosis is difficult, surgery is typically considered the best option. Given the potential for local recurrence and the uncertain long-term prognosis, regular follow-up is necessary

Preparation of WO3 gel electrochromic device by simple two-step method

Gel electrochromic devices (gel ECDs) have promising application prospects in smart windows due to their energy-saving effects and superior electrochromic performance. However, the rapid preparation of gel electrolytes is one of the reasons limiting the further promotion of gel ECDs. In this work, we proposed a simple doctor blade method to prepare PVDF gel electrolytes with high ionic conductivity (3.7 * 10(-3) S cm(-1)) and excellent mechanical properties (268% strain), accompanied by high transmittance (exceeding 95% within 600-1100 nm). And we also prepared WO3 gel ECDs by using PVDF gel electrolytes as electrolyte layer. Compared with liquid ECDs, WO3 gel ECDs' lifetime has increased by 33%, mainly due to the increased oxidation potential with PVDF gel electrolyte addition, enhancing oxidation resistance. In addition, the large-area flexible gel ECDs (6 * 10 cm(2)) were assembled, which provides practical guidance for preparing large-area flexible gel ECDs in the future

Synthesis of high-performance electrochromic thin films by a low-cost method

Metal-doping is an effective method to adjust the physical and chemical properties of semiconductor metal oxides. This work adopts a simple solvothermal method to synthesize Mo-doped tungsten oxide nanoparticles. The high-performance electrochromic films can be homogenously formed on ITO glass without post-annealing. Compared with pure WO3 films, the optimized Mo-doped WO3 films show improved electrochromic properties with significant optical contrast (68.3% at 633 nm), the short response time (6.3 s and 3.9 s for coloring and bleaching, respectively), and excellent coloration efficiency (107.2 cm(2) C-1). The improved electrochromic behavior is mainly due to the increasing diffusion rate of Li+ in Mo-doped WO3 films (increased 20% than that of pure WO3 films). The porous surface of Mo-doped WO3 film shortens the diffusion path of Li+. Besides, Mo doping reduces the resistance and improves conductivity. Furthermore, 2at% Mo-doped WO3 films indicate satisfactory energy-storage properties (the specific capacitance is 73.8 F g(-1)), resulting from the enhanced electrochemical activity and fast electrical conductivity. This work presents a practical and economical way of developing high-performance active materials for bifunctional electrochromic devices

Nanostructured Co3O4 for achieving high-performance supercapacitor

Supercapacitors with cobalt oxide (Co3O4) electrode are a kind of strong candidates for achieving high capacity storage energy devices. However, the reported capacitances lower than the theoretical values are undesirable. In this study, a high-performance supercapacitor by using the Co3O4 electrode with a porous nanostructure is enabled by the calcination treatment of metal organic framework ZIF-67. Of note, the resulting Co3O4 electrodes shows high specific capacitance of 1015 F/g under a current density of 1 A/ g. Additionally, it exhibits energy density of 36.6 Wh/kg at a power density of 189.5 W/kg and maintains capacitance retention of 78.2% after 5000 cycles at 8 A/g. The strategy proposed here provides a good way to synthesize nanostructured Co3O4, a candidate for constructing high-capacitance energy storage devices. (c) 2020 Elsevier B.V. All rights reserved

Construction of hierarchical structure of Co3O4 electrode based on electrospinning technique for supercapacitor

The design and synthesis of hierarchical micro-nano structures of transition metal oxides have played an essential role in the supercapacitor field. In this work, in situ three-dimensional construction of nanoporous cobalt oxide (Co3O4) has been derived from the metal-organic framework (MOF) distributed evenly in electrospun polyacrylonitrile nanofibers. Due to large specific surface area and network architectures, the as-synthesized Co3O4 electrode notably presents a high specific capacitance of 970 F/g at a current density of 1 A/g. Besides, the as-obtained electrode exhibits a high energy density of 54.6 Wh/ kg at a power density of 360.6 W/kg and maintains a capacitance retention of 77.5% after 5000 cycles at 6 A/g. Therefore, this method paves a way to produce the nanoporous MOF-derived Co3O4 network architecture as advanced electrodes materials, which shows an application potential for the energy storage industry.

A facile method to improve the stability and efficiency of CsPbI2Br perovskite solar cells prepared at low temperature

CsPbI2Br has become the focus of researchers in recent years due to its excellent thermal stability compared to the organic-inorganic hybrid perovskites. However, it requires high temperature to form cubic phase, and it is difficult to maintain the cubic phase in the high humidity ambient. By adding 30 mu L levulinic acid (LA) to the CsPbI2Br precursor solution, cubic phase CsPbI2Br can be obtained by spin-coating three minutes (TMS) at room temperature (RT) instead of high temperature. Based on the TMS, highly quality cubic phase CsPbI2Br film can be obtained at 80 degrees C annealing temperature, the stability of cubic phase CsPbI2Br can be significantly improved by adding LA in the CsPbI2Br precursor solution. Based on this, CsPbI2Br cells without LA achieve 11.68% power conversion efficiency (PCE) at low temperature of 80 degrees C and the corresponding stabilized power output is 10.31%. Furthermore, 10 mu L LA addition CsPbI2Br cells keep its 50% PCE after 10 days under 35%RH and RT. This has found a new way to improve the stability of inorganic perovskite solar cells, and increasing its potential in flexible solar cells

Achieving multifunctional smart textile with long afterglow and thermo-regulation via coaxial electrospinning

People working in extremely cold environments, such as traffic police in the winter, need clothes that can keep them warm and show safety signals simultaneously, which is very meaningful for them. Based on such a requirement, developing the smart textiles integrating thermal regulation and luminescence functions is highly desired. Here, we utilized the coaxial electrospinning to achieve luminous thermo-regulated smart textiles. The paraffin wax (PW) and long afterglow phosphors were incorporated into the nanofiber with the PW as core and the polyacrylonitrile (PAN)/phosphors as sheath successfully. Moreover, the textiles possess the PW encapsulation efficiency of 52.1% (enthalpy of 64.08 J/g) and the afterglow can last for about 1 h. Hence, this work paves a novel avenue for multifunctional textiles and provides a meaningful guidance for comfort smart wearable. (C) 2019 Elsevier B.V. All rights reserved

Tuning thermochromic performance of VOx-based multilayer films by controlling annealing pressure

In this work, the nominal SiNx/NiCr/NiCrOx/VOx/NiCrOx/NiCr/SiNx multilayer films deposited on glass were obtained by magnetron sputtering and subsequent rapid thermal annealing (RTA) in N-2 at 0.5-2000Pa pressure. Annealing pressure influenced the radiation thermal resistance, which can directly determine the crystallization and thermochromic performance of the VOx-based multilayer films. The VO2 (M) film is very difficult to form under low annealing pressure because of insufficient oxygen and low-valence metal oxides in NiCrOx film. Therefore, the thermochromic performance is seriously deteriorated by the drastic diffusion between NiCrOx and VOx. Based on the phase transition temperature (T-c) and good crystallization, the wider process window of 80 Pa-300 Pa has been obtained successfully. Additionally, the films exhibit the optimal thermochromic performance with the solar regulation (Delta T-sol) of 18.4% and the luminous transmittance (T-lum) of 40.5%. Moreover, the T-c can be reduced to 54 degrees C by regulating annealing pressure without element doping. The results provide guidance for commercial production and quality consistency of VOx-based smart glass in building energy conservation
