    Abstract Coronavirus disease 2019 [COVID-19] is a global health threat caused by severe acute respiratory syndrome coronavirus 2 [SARS-CoV2] that requires two proteins for entry: angiotensin-converting enzyme 2 [ACE2] and -membrane protease serine 2 [TMPRSS2]. Many patients complain from pneumonia, cough, fever, and gastrointestinal (GI) problems. Notably, different TRP channels are expressed in various tissues infected by SARS-CoV-2. TRP channels are cation channels that show a common architecture with high permeability to calcium [Ca

    Abstract Chemotherapy-induced peripheral neuropathy (CIPN) is a significant adverse effect of many anticancer drugs. Current strategies for the management of CIPN pain are still largely unmet. The aim of this study is to investigate the antinociceptive potential of combining tramadol with the synthetic cannabinoid WIN55212, and to evaluate their associated adverse effects, separately or in combination, in a CIPN rat model, and to investigate their ability to modulate the transient receptor potential vanilloid 1 (TRPV1) receptor activity. Von Frey filaments were used to determine the paw withdrawal threshold in adult male Sprague-Dawley rats (200-250 g) following intraperitoneal (i.p) injection of cisplatin. Single cell ratiometric calcium imaging was used to investigate WIN55212/tramadol combination ability to modulate the TRPV1 receptor activity. Both tramadol and WIN55212 produced dose-dependent antinociceptive effect when administered separately. The lower dose of tramadol (1 mg/kg) significantly enhanced the antinociceptive effects of WIN55212 without interfering with core body temperature. Mechanistically, capsaicin (100 nM) produced a robust increase in [Ca 2+ ] i in dorsal root ganglia (DRG) neurons ex vivo . Capsaicin-evoked calcium responses were significantly reduced upon pre-incubation of DRG neurons with only the highest concentration of tramadol (10 µM), but not with WIN55212 at any concentration (0.1, 1 and 10 µM). However, combining sub-effective doses of WIN55212 (1 µM) and tramadol (0.1 µM) produced a significant inhibition of capsaicin-evoked calcium responses. Combining WIN55212 with tramadol shows better antinociceptive effects with no increased risk of hypothermia, and provides a potential pain management strategy for CIPN.

    Abstract Arbutus andrachne L. is a medicinal plant that grows in Jordan and has many valuable effects. In the present study, the anti-nociceptive effect of A. andrachne methanolic leaf extract was determined in mice using thermal and chemical tests. Our findings show that different doses of A. andrachne extract reduced the number of writhings significantly compared to control group. The leaf extract also reduced the time of paw licking in the early and late phases of formalin test. In all the conducted tests, 300 mg/kg body wt. was the best effective dose. A peroxisome proliferator-activated receptor alpha (PPARα) antagonist reversed the action of the plant extract in the early phase of formalin test while antagonists of the PPARα, PPAR gamma (PPARγ) and cannabinoid 1 (CB1) receptors were responsible for abolishing its effect in the late phase of this test. Also, the extract administration increased the latency time in hot plate and tail flick, an effect that was reversed by the antagonists of PPARγ, CB1 and transient receptor potential vanilloid 1 (TRPV1). No effect was noticed for α

    Abstract Achillea biebersteinii is a perennial aromatic herb that grows in the Mediterranean area. The leaves of this plant are used in foods as bittering and appetizing agents. In folk medicine, it is used for the treatment of stomachache and abdominal pain. In this study, the analgesic effect of A. biebersteinii methanolic flower extract was tested in three pain models, namely: writhing, tail-flick and paw-licking (formalin) tests. A. biebersteinii extract inhibited abdominal cramps produced by acetic acid. The effect of A. biebersteinii was better than that of 70 mg/kg indomethacin. In tail flick, A. biebersteinii extract increased latency at 30 min and was as effective as 100 mg/kg diclofenac sodium. In formalin test, A. biebersteinii extracts decreased paw-licking and flinching response in early and late phases. Atropine blocked the action of A. biebersteinii extract (300 mg/kg) in the late phase of formalin test as well as in writhing and tail-flick tests. GC-MS analysis revealed that ascaridole and iso-ascaridole were the main constituents of A. biebersteinii flower extract. In conclusion, this study shows for the first time that the antinociceptive effect of A. biebersteinii is mediated by the cholinergic receptor.

    Abstract Objective: To explore the anti-inflammatory and antipyretic effects of methanolic leaf extract from Arbutus andrachne and its mechanism of action. Methods: Paw edema was induced by intraplantar (i.pl.) injection of λ-carrageenan (1% w/v, 100 μL/paw) while pyrexia was evoked by intraperitoneal (i.p.) injection of 20% baker’s yeast (20 mL/kg body wt) in male Wistar rats. The anti-inflammatory and antipyretic effects of Arbutus andrachne methanolic leaf extract were explored by injecting rats with different doses of the plant extract (150, 300, and 600 mg/kg body wt, i.p.). Selective antagonists for transient receptor potential vanilloid-1 (TRPV1), cannabinoid receptor 1 (CB1), and alpha-2 adrenergic receptor (a2-AR) were used to unravel the extracts’ mechanism of action. Blood samples were collected from the heart of rats to measure the levels of interleukin-6 (IL-6) and prostaglandin E2 (PGE2) by enzyme-linked immunosorbent assay. Results: The extract exhibited potent anti-inflammatory activity by decreasing paw thickness and IL-6 levels. In addition, yeast-evoked pyrexia was attenuated by the extract treatment via TRPV1 and CB1 receptors and a reduction in PGE2 levels. No significant effects were found for a2-AR. Moreover, the rats that received the plant extract demonstrated similar responses to the positive control group. Conclusions: Arbutus andrachne can be a good candidate for treating inflammation and pyrexia and should be further investigated.

    Abstract Cough is one of the most common complaints for which sufferers seek medical assistance. However, currently available drugs are not very effective in treating cough, particularly that which follows an upper respiratory tract infection. Nonetheless, there has been a significant increase in our understanding of the mechanisms and pathways of the defensive cough as well as the hypersensitive/pathophysiological cough, both at airway and central nervous system (CNS) levels. Numerous molecules and signaling pathways have been identified as potential targets for antitussive drugs, including neurotrophins (NTs). NTs belong to a family of trophic factors and are critical for the development and maintenance of neurons in the central and peripheral nervous system including sympathetic efferents, sensory neuron afferents, and immune cells. Nerve growth factor (NGF) was the first member of the NT family to be discovered, with wide ranging actions associated with synapse formation, survival, proliferation, apoptosis, axonal and dendritic outgrowth, expression and activity of functionally important proteins such as ion channels, receptors, and neurotransmitters. In addition, NGF has been implicated in several disease states particularly neuropathic pain and most recently in the sensitization of the cough reflex. This review will briefly address the peripheral and central sensitization mechanisms of airway neurons and will then focus on NGF signaling and its role in cough hypersensitivity.

    Abstract Background: Moringa peregrina (M. peregrina) is an edible, drought-resistant tree that is native to semi-arid countries. It is used as a painkiller in folk medicine. Aims: To study the antinociceptive effects of the leaf extract of M. peregrina in mice. Study Design: Animal experimentation. Methods: We employed thermal (hot plate and tail-immersion tests) and chemical (writhing and formalin tests) pain models in male BALB/c mice (eight animals per group) to investigate the mechanisms involved in the antinociceptive actions of M. peregrina. Additionally, we identified the chemical constituents present in the extract of M. peregrina by using liquid chromatography-mass spectrometry analysis, and predicted the possible active constituents that interact with the receptor based on molecular docking simulations. Results: In the writhing test, 200 mg/kg of M. peregrina extract restricted abdominal cramps by up to 55.97% (p<0.001). Further, it reduced the time of paw-licking in the early and late phases of formalin test by up to 56.8% and 65.5%, respectively, as compared to the percentage inhibitions of 50.5% and 48.4% produced by 30 mg/kg diclofenac sodium in the early and late phases, respectively (p<0.05). This effect was abrogated by yohimbine (1 mg/kg, intraperitoneally), but not by methysergide (5 mg/kg, intraperitoneally), in the late phase only, which indicates that the action of M. peregrina in formalin test is not mediated by 5-HT2 serotonin receptors, but rather via α2-adrenergic receptors. In the hot plate test, but not on tail-immersion test, the high dose (400 mg/kg) of the extract increased the latency time after 30 minutes of its administration. Yohimbine antagonized the action of M. peregrina in the hot plate test. Based on LC-MS analysis, the major constituents found in M. peregrina methanolic extract were chrysoeriol 7-O-diglucoside, lupeol acetate, quercetin, and rutin. Depending on the molecular docking results, the activity of M. peregrina extract could be due to the binding of chrysoeriol ...
