1,2-Bis(4-nitro­benzo­yl)hydrazine

The title mol­ecule, C14H10N4O6, crystallizes with one half-mol­ecule in the asymmetric unit; the mid-point of the N—N bond lies on an inversion centre. The nitro and amide groups are twisted with respect to the benzene ring, making dihedral angles of 14.6 (5) and 31.1 (5)°, respectively. In the crystal structure, mol­ecules are linked through N—H⋯O hydrogen bonding between the imino and carbonyl groups

Review on the development of kelp industry in Shandong province: A comparative perspective

Shandong and Fujian are two important provinces regarding the development of the seaweed industry, which shared three-fourths of the national seaweed yield in the year 2020. The present study has analyzed the overall situation of the seaweed industry in Shandong and Fujian provinces by comparing annual output, farming area, and species structure. The current status of Laminaria japonica cultivation in two provinces is also compared to the production process, industrial organization, progress, and innovation. On this foundation, the following development strategies are proposed for the seaweed industry in Shandong Province: (1) change the mindset based on the present industrial basis, (2) retain and transform innovative achievements, (3) enhance the services of associations and organizations and (4) construct brands based on current market share

Successful resuscitation of a patient With electrical storm over 7 days: a case report

Abstract: A 75 year old woman with atrial fibrillation-related tachycardia-induced cardiomyopathy suffered ventricular fibrillation induced by dobutamine and was successfully defibrillated into atrial fibrillation in hospital. During the following 7 days, she suffered a cardiac electrical storm with 55 episodes of ventricular tachycardia rapidly degenerating to ventricular fibrillation and was converted with a total of 51 defibrillations and 4 chest compressions. Sinus rhythm was restored by electric cardioversion in the second episode of ventricular fibrillation. There was no response to the use of any recommended anti arrhythmic drugs. However, the use of chlorpromazine and promethazine surprisingly stabilized her heart rhythm. During a two-year follow-up period, the patient has remained free of ventricular fibrillation episodes and maintained sinus rhythm. [Guo YL, Zhang HY, Han YF, Zhang SL.
