Effectiveness of Delayed Surgical Treatment for Distal Radius Fractures With Loss of Reduction.

Purpose: This study investigated the effectiveness of volar plate surgery in patients with distal radius fractures (DRFs) initially treated nonsurgically but later experiencing reduction loss during follow-ups. Specifically, it assessed the impact of early surgery (E) (<3 weeks) versus delayed surgery (D) (3-6 weeks) on wrist function in surgically treated DRFs.

Methods: This retrospective study included 131 patients who underwent surgery after loss of reduction.

Water monitoring with an automated smart sensor supported with solar power for real-time and long range detection of ferrous iron.

Low-power and smart sensing systems for iron detection are necessary for monitoring of water quality. Here, a potentiometric Fe-selective electrode (ISE) was fabricated based on cyanomethyl -methyl--phenyl dithiocarbamate for the first time as an ionophore. Under optimal conditions, the ISE showed a Nernstian slope of 29.

Three materials, including polyvinyl chloride, polyethylene terephthalate and polyimide, were used as substrates for fabricating ion-selective electrodes (ISEs) using stencil printing, screen-printing and laser engraving, respectively.

A smartphone-assisted hybrid sensor for simultaneous potentiometric and distance-based detection of electrolytes.

At home electrolyte analysis is of growing interest due to the importance for early diagnosis for various diseases.

Rapid prototyping of ion-selective electrodes using a low-cost 3D printed internet-of-things (IoT) controlled robot.

We report automated fabrication of solid-contact sodium-selective (Na-ISEs) and potassium-selective electrodes (K-ISEs) using a 3D printed liquid handling robot controlled with Internet of Things (IoT) technology.

The robot is more compact (25 × 30 × 35 cm) and user-friendly than commercially available systems and does not require mechatronic experience.

Development and comparison of various rod-shaped mini-reference electrode compositions based on Ag/AgCl for potentiometric applications.

Several fundamentally similar, miniaturized solid-state reference electrode designs, and their fabrication and comparison are described in this article.

Internet of Things Implementation of Nitrate and Ammonium Sensors for Online Water Monitoring.

In this work, we proposed a new wireless sensor to contribute to research aimed at continuous monitoring of nitrate and ammonium in water, which as leading agents of water pollution have become the source of a serious problem today. In this research, a well-implemented application of an electroanalytical sensor was achieved by combining it with the internet of things (IoT) concept, which is the most modern technique for wireless data collection. We developed a portable IoT system and ion-selective nitrate and ammonium electrodes and monitored the nitrate and ammonium levels of the water online.

Tuberculosis osteomyelitis of the tibia mimicking Brodie abscess: A case report and review of the literature.

Background: Tuberculosis osteomyelitis is rarely seen in the diaphyseal bones. It may be confused with Brodie's abscess due to similar clinical, radiological and laboratory findings. Late diagnosis of the disease causes bone destruction.

The effect of platelet-rich plasma in bone-tendon integration.

Background: The operative reconstruction of a torn or insufficient anterior cruciate ligament has become a routine surgical procedure in orthopedics. The long-term success of an anterior cruciate ligament reconstruction depends on the ability of the graft to heal adequately in a bone tunnel. Investigators studying reconstructions described healing within a tunnel as osseous ingrowth and incorporation.

Tendon-holding capacities of two newly designed implants for tendon repair: an experimental study on the flexor digitorum profundus tendon of sheep.

Background: Two main factors determine the strength of tendon repair; the tensile strength of material and the gripping capacity of a suture configuration. Different repair techniques and suture materials were developed to increase the strength of repairs but none of techniques and suture materials seem to provide enough tensile strength with safety margins for early active mobilization. In order to overcome this problem tendon suturing implants are being developed.
