Clinical Characteristics of Testicular Torsion and Identification of Predictors of Testicular Salvage in Children: A Retrospective Study in a Single Institution.

Purpose: Testicular torsion (TT) is a serious surgical emergency. Prompt diagnosis and treatment of TT are essential to improve the incidence of salvaged testes. The aim of this study was to evaluate the historical features, physical examination findings, laboratory tests, and ultrasound examinations in children with TT, as well as to identify the predictors of testicular salvage in children.

Adsorption performance of antimony by modified iron powder.

Antimony pollution resulting from industrial production is a great threat to the environment, ecology and the human body. Zero-valent iron powder is low-cost and easy to obtain. Nevertheless, the lower adsorption capacity limits its application when it is used as an adsorbent.

Granular tri-metal oxide adsorbent for fluoride uptake: Adsorption kinetic and equilibrium studies.

A novel adsorbent embedding Mg-Al-Zr mixed oxides with millimetre-sized calcium alginate beads (SA-CMAZ) was synthesized, characterized, and applied for the secondary removal of fluoride from wastewater. Key factors affecting the fluoride adsorption, including initial fluoride concentration, contact time, initial pH and coexisting anions, were investigated. The results showed that fluoride could be removed by SA-CMAZ over a wide pH range, from 4 to 10.

Effect of competing ions and causticization on the ammonia adsorption by a novel poly ligand exchanger (PLE) ammonia adsorption reagent.

In this paper, a poly ligand exchanger, Cu(II)-loaded chelating resin named ammonia adsorption reagent (AMAR), bearing the functional group of weak iminodiacetate acid, was prepared to efficiently remove ammonia from solutions. Batch adsorption equilibrium experiments were conducted under a range of conditions. The effects of pH on the removal of ammonia by AMAR were investigated at 25 °C.

A novel poly ligand exchanger - Cu(II)-loaded chelating resin for the removal of ammonia-nitrogen in aqueous solutions.

In this paper, a poly ligand exchanger, Cu(II)-loaded chelating resin bearing the functional group of weak iminodiacetate acid was prepared to efficiently remove ammonia from solutions. Batch adsorption equilibrium experiments were conducted under a range of conditions to determine the optimum adsorption conditions. The effects of contact time, pH, resin dosage and temperature on the removal of ammonia by a Cu(II)-loaded resin were determined.

[Preparation of Mg-Al-Me(Me=La, Ce, Zr) Composite Oxides for Efficient Fluoride Uptake].

The Mg-Al-Me(Me=La, Ce, Zr) composites were prepared by co-precipitation method of Mg, Al, Me(Me=La, Ce, Zr) salt solutions with a molar ratio of 20:1:4. The sample were calcined at 500℃ for 5h as the adsorbents for removal of fluoride. The adsorbents were characterized by scanning electron microscopy (SEM) and X-ray diffraction (XRD).

Single scrotal incision orchiopexy versus the inguinal approach in children with palpable undescended testis: a systematic review and meta-analysis.

Purpose: We performed a systematic review and meta-analysis to compare the efficacy and safety between single-incision, transscrotal orchidopexy, and the traditional inguinal orchidopexy in children.

Methods: A systematic search of the electronic databases was conducted to identify studies compared the transscrotal orchidopexy (SO) and inguinal orchidopexy (IO) for children. Parameters, such as operative time, the incidence of patent processus vaginalis, and postoperative complications, including wound infection, testicular atrophy, testicular reascent, hernia, or hydrocele, were pooled and compared by meta-analysis.

Laparoscopic versus open splenectomy in children: a systematic review and meta-analysis.

Purpose: We conducted a systematic review and meta-analysis to compare the clinical outcomes between laparoscopic splenectomy and the traditional open splenectomy in children.

Methods: Literature searches were conducted to identify studies having compared the laparoscopic splenectomy (LS) and open splenectomy (OS) for children. Parameters such as operative time, blood loss, length of postoperative stay, the removal of accessory spleens and postoperative complications including postoperative high fever, acute chest syndrome (ACS), and ileus were pooled and compared by meta-analysis.
