Summary: This study demonstrates that the endogenous amino acid l-cysteine can modulate Ca(V)2.3 channels and plays an important role in visceral pain processing. The results also reveal contrasting roles of Ca(V)2.3 channels in mediating visceral nociception in the peripheral and central pain pathways.

Summary: Vortioxetine has been shown to have analgesic efficacy in trigeminal, visceral, and somatic inflammatory pain, potentially mediated through various receptors such as 5-HT, adrenergic, and cholinergic receptors.

Summary: Although lacking evidence, cannabis may be used as an adjunct or alternative to opioids. This study found that CB1R agonists can reduce colonic nociception in mice, while CB2R agonists do not have this effect. Combining CB1R and opioid agonists can alleviate pain responses and reduce side effects, which may help in reducing opioid dosage.

Summary: Pain in animals is a concern due to the lack of verbal communication, leading to possible undertreatment. This study evaluated the effectiveness of a local anaesthetic agent in dogs undergoing abdominal surgery. The results showed no significant difference in pain and sedation level, with slightly higher scores in dogs treated with ropivacaine. The conclusion was that the dosage and concentration used in this study should not be investigated further for clinical use.

Summary: This study reveals that the analgesic effect of EA is associated with the suppression of RIP3 and NLRP3 expression in the SDH, providing potential insights into the underlying spinal mechanisms involved in the analgesic effect of EA.

Summary: The 80% methanol root extract of Verbasicum sinaiticum was found to possess peripheral and central analgesic as well as anti-inflammatory activity, possibly due to the presence of phytochemicals.

Summary: This study evaluated the effects of pharmacological inhibition of CysLT1R on acetic acid-induced D-IBS in rats. The results showed that montelukast can reduce pain responses, decrease stool frequency, and improve depression-like behavior in IBS rats. Furthermore, montelukast decreases inflammatory cytokine levels and histopathological inflammatory injuries while increasing anti-inflammatory cytokine levels. These findings suggest the potential beneficial effects of montelukast in the management of D-IBS symptoms, possibly through modulating CysLT1R-mediated NF-kappa B signaling.

Summary: Descending control of nociception (DCN) is a reversible biomarker of chronic pain and can be manipulated through neurochemical modulation. This research provides insight into potential pharmacological strategies for preventing persistent pain.

Summary: This study evaluated the perceived pain in zebrafish larvae by observing behavioral changes. The results showed that acetic acid induced behavioral changes in zebrafish larvae, and compounds such as ethanol, ibuprofen, and paracetamol could prevent these changes. In addition, antagonists and inhibitors of specific channels also prevented the behavioral changes induced by acetic acid. These findings suggest that zebrafish can serve as a translational model for studying pain, as their early developmental stages exhibit behavioral responses similar to mammals.

Summary: The therapeutic effects of electroacupuncture (EA) on visceral pain and anxiety comorbidity in patients with inflammatory bowel disease (IBD) is well known. This study investigated the involvement of the ventral hippocampus (vHPC) and the cannabinoid type 1 receptors (CB1R) in the mechanism of EA's effects on anxiety and pain. The results demonstrated that EA alleviated visceral hyperalgesia and anxiety in IBD mice by reducing the expression of CB1R in GABAergic neurons and activating CB1R in glutamatergic neurons in the vHPC.

Summary: Both TRPA1 and purinergic P2X receptors are proposed as potential targets for the treatment of visceral pain. While a low dose of mustard oil induces visceral pain dependent on TRPA1, a higher dose results in pain mostly independent of TRPA1 but enhanced by ATP released from damaged tissues. Thus, TRPA1 inhibition may not be sufficient to decrease visceral pain significantly during tissue injury, and purinergic antagonism appears to be a more effective strategy.

Summary: The aqueous leaf extract of Blighia sapida contains bioactive compounds such as chlorogenic acid, saponins, tannins, and quercetin. It exhibited analgesic properties in mice, specifically inhibiting acetic acid-induced writhing and formalin-induced paw licking pain in the inflammatory phase. The analgesic activity of the extract is mediated by peripheral mechanisms rather than central mechanisms.

Summary: Cinnabarinic acid (CA), a trace metabolite of kynurenine, activates mGlu4 and Ah receptors and has analgesic effects on inflammatory and neuropathic pain. This study demonstrates that the modulation of pain thresholds by CA depends on the recruitment of mGlu4 and Ah receptors.

Summary: Capsaicin, a compound found in hot chili peppers, is a known analgesic but its high pungency limits its application. To address this issue, novel capsaicin analogues were developed with reduced pungency. These analogues have been shown to alleviate pain behavior and reduce thermal sensitivity.

Summary: Roselle is a common name for a mixture of anthocyanin dyes derived from the plant Hibiscus sabdariffa, which can be used as a biological stain and a nuclear stain. Proper oxidation and mordanting are needed for roselle to be an effective nuclear stain. The study suggests a rational staining approach and offers suggestions for improving the use of roselle in the scientific community.

Summary: The natural colorant roselle has been used as a histological dye for 40 years, typically requiring oxidation for staining preparation, though it is not actually necessary. Roselle is a complex mixture of four compounds, with only three being colored, and the color can be influenced by pH.
