Association between diabetes mellitus and tinnitus: A meta-analysis.

Diabetes mellitus (DM) has been suggested as a potential risk factor for tinnitus, but evidence remains inconclusive. This meta-analysis aimed to evaluate the association between DM and tinnitus by systematically reviewing and synthesizing data from observational studies. A comprehensive literature search was conducted in PubMed, Embase, and Web of Science up to August 16, 2024.

Rapid synthesis of iron 1,4-naphthalenedicarboxylate by microwave irradiation with enhanced gas sorption.

A high quality crystalline porous coordination polymer (PCP), Fe(OH)(1,4-NDC)·2H2O (1,4-NDC = 1,4-naphthalenedicarboxylate), was successfully prepared using a rapid and efficient microwave irradiation method (hereafter termed M-PCP-Fe). It was noteworthy that the microwave irradiation method reduced the reaction time considerably to 1 min, while it took three days for the conventional hydrothermal method to prepare non-uniform crystal morphologies in a one-pot manner (hereafter termed H-PCP-Fe). The effects of microwave irradiation time, temperature and concentration were also investigated.
