Objective: To determine the efficacy of reversal steps stapedotomy in the treatment of otosclerosis.
Method: From January 2006 to December 2009, a total of 70 patients (81 ears) with otosclerosis who underwent stapedotomy were retrospectively evaluated. Among these 81 ears, 41 ears underwent classical stapedotomy and 40 ears underwent reversal steps stapedotomy. We compared the postoperative results of pure tone tes , the intraoperative complications of stapes and incus and the incidence rate of postoperative vertigo after surgery between the two groups.
Result: The rate of postoperative air bone gap < or = 20 dB was 70.7% in the classical stapedotomy group and was 80.0% in reversal steps stapedotomy group. There were no significant differences between the two groups (P =0.181). The reversal steps stapedotomy group seem to had less complications of stapes and incus. The incidence rate of postoperative vertigo in reversal steps stapedotomy group significantly lower than in classical stapedotomy group (P = 0.037).
Conclusion: Reversal steps stapedotomy can effectively improve the hearing of patients with otosclerosis and can reduce the complications of stapedotomy.

Objective: Aberrant 6-phosphofructo-2kinase/fructose-2,6-bisphoshatase 3 (PFKFB3) expression is tightly correlated with multiple steps of tumorigenesis; however, the pathological significance of PFKFB3 in macrophages in patients with rheumatoid arthritis (RA) remains obscure. In this study, we examined whether PFKFB3 modulates macrophage activation and promotes RA development.
Method: Peripheral blood mononuclear cells (PBMCs) from patients with RA, THP-1 cells, and bone marrow-derived macrophages from conditional PFKFB3-knockout mice were used to investigate the mechanism underlying PFKFB3-induced macrophage regulation of RA.
Temperature-Dependent Water Oxidation Kinetics: Implications and Insights.

As a vital process for solar fuel synthesis, water oxidation remains a challenging reaction to perform using durable and cost-effective systems. Despite decades of intense research, our understanding of the detailed processes involved is still limited, particularly under photochemical conditions. Recent research has shown that the overall kinetics of water oxidation by a molecular dyad depends on the coordination between photocharge generation and the subsequent chemical steps.

The thermal dehydration of sodium carbonate monohydrate (SC-MH) exhibits kinetic characteristics that are typical of the thermal decomposition of solids with a reversible nature. One of the characteristics is the physico-geometrical constraints of the reaction due to the heterogeneous reaction feature. Another factor is the considerable impact of the atmospheric and self-generated water vapor on the kinetics.

MicroRNAs (miRNAs or miRs) are small, non-coding RNAs that play a crucial role in gene regulation, making them potential biomarkers for various diseases. In the field of veterinary medicine, there is a growing interest in exploring the diagnostic and therapeutic potential of miRNAs in kidney diseases affecting dogs and cats. This review focuses on the use of urinary miRNAs as biomarkers for chronic kidney disease (CKD) in these companion animals.

Achieving axially chiral biaryl dialdehydes through asymmetric catalysis remains significantly challenging due to the lack of efficient strategies. In this report, we developed a rhodium-catalyzed enantioselective C-H amidation through chiral transient directing group strategy. With this new approach, a series of axially chiral amido dialdehydes were achieved in up to 86% yields with 99.
