Use of kersetin and fisetin flavonoids in combination with pregabalin and gabapentin in the treatment of neuropathic pain.

We purposed to explore the consequences of the use quercetin and fisetin alone and in combination with pregabalin and gabapentin, which are used in the management of neuropathic pain, and on neuropathic pain in general. The anti-allodynic effect of various doses (5, 10, and 20 mg/kg) of quercetin and fisetin, both singly and in combination with pregabalin and gabapentin, was evaluated by developing a neuropathic pain model induced by chronic constrictive nerve damage in rats. The effectiveness of these flavonoids was investigated by combining them with gabapentin (50 mg/kg) and pregabalin (15 mg/kg), choosing the effectual dose of 10 mg/kg and the dose of 5 mg/kg, which did not show significant antiallodynic effects.

Design, Synthesis, and Evaluation of a New Series of Indole-Chalcone Hybrids as Analgesic and Anti-Inflammatory Agents.

Indole-chalcone hybrids have burst into prominence as potent weapons in the battle against pain and inflammation due to their unique features, allowing these ligands to form pivotal interactions with biological targets.

Trade agreements and CO emissions in Asian countries: accounting for institutional heterogeneity.

This paper aims to measure the impact of environmental provisions in free-trade agreements on pollution levels in 40 Asian economies for the period 1990-2019.

We exploit such changes to assess their influence on pollution emissions.

FDI and CO emissions in developing countries: the role of human capital.

FDI inflows remain an important source of economic growth and technology transfer for developing countries. However, the proponents of the pollution haven hypothesis (PHH) argue that FDI inflows may result in the production of polluted goods in poor economies. The empirical testing of PHH reveals conflicting outcomes on the subject.

The imidazoline receptors and ligands in pain modulation.

Pain is an unpleasant experience and effects daily routine negatively. Although there are various drugs, many of them are not entirely successful in relieving pain, since pain modulation is a complex process involving numerous mediators and receptors. Therefore, it is a rational approach to identify the factors involved in the complex process and develop new agents that act on these pain producing mechanisms.
