Comparative Study
Comparison of the analgesic effects of pulse radiofrequency and cryoablation in rabbits with mental nerve neuropathic pain.
After mental nerve injury, several sensory disorders may occur. The alterations in sensation may differ from mild paresthesia to complete anesthesia, or neuropathic pain. Neuropathic pain is a difficult clinical condition to manage. The aim of this study was to compare the analgesic effects of pulsed radiofrequency (PRF) and cryoablation in an experimental mental nerve neuropathic pain model in rabbits. ⋯ Both PRF and cryoablation therapies are successful in the treatment of experimentally induced mental nerve neuropathic pain in rabbits.

In this study, we investigated the retention of two attachment types, Straumann ball (SB) and Straumann Locator® (SL) attachments, on different implant angulations and identified the most appropriate treatment type or attachment system for each angulation. ⋯ In implants with a 20° angle, retention of stud attachments decreased more than ball attachments after use. Thus, the total angle between the implants should not be <20° if long-term retention is desired when using stud attachments. For implants with angles >20°, 6-month patient controls are required to control retention of attachments by considering factors in the mouth with the two tested attachment systems.

The entire genetic information carried by an organism makes up its genome. Genes have a diverse number of functions. They code different proteins for normal proliferation of cells. However, changes in the base sequence of genes affect their protein by-products which act as messengers for normal cellular functions such as proliferation and repairs. Salient processes for maintaining the integrity of the genome are hinged on intricate mechanisms put in place for the evolution to tackle genomic stresses. ⋯ Knowledge on how cells detect and repair DNA damage through an array of mechanisms should allay our anxiety as regards cancer development. More studies on DNA damage detection and repair processes are important toward a holistic approach to cancer treatment.

In vitro and in vivo comparison of orthodontic indirect bonding resins: A prospective study.
The aim of this study was to evaluate in vitro shear bond strength (SBS) and in vivo bond survival rates of brackets bonded using orthodontic indirect bonding resins. ⋯ In vitro study showed lower SBS with chemically-cured indirect bonding resin than flowable light-cured resin and the control group, but in vivo failure rates of both indirect resins were found to be adequate for clinical usage.

Mortality in patients with severe acute cholecystitis (AC) remains high, and the prognosis for elderly patients tends to be poor. A comparative analysis of clinical, laboratory, and abdominal computed tomography (CT) parameters was conducted in this study to investigate the effectiveness of each index for predicting clinically severe AC in elderly patients in the emergency department (ED). ⋯ The CT parameters of increased pericholecystic fat stranding and pericholecystic fluid collection with an NLR cutoff of 9.9 were useful for predicting the severity of AC in elderly patients in the ED.
