    PMID: 30042373 DOI: 10.3390/ijms19082164
    Pain has been considered as a concept of sensation that we feel as a reaction to the stimulus of our surrounding, putting us in harm's way and acting as a form of defense mechanism that our body has permanently installed into its system. However, pain leads to a huge chunk of finances within the healthcare system with continuous rehabilitation of patients with adverse pain sensations, which might reduce not only their quality of life but also their productivity at work setting back the pace of our economy. It may not look like a huge deal but factor in pain as an issue for majority of us, it becomes an economical burden. Although pain has been researched into and understood by numerous researches, from its definition, mechanism of action to its inhibition in hopes of finding an absolute solution for victims of pain, the pathways of pain sensation, neurotransmitters involved in producing such a sensation are not comprehensively reviewed. Therefore, this review article aims to put in place a thorough understanding of major pain conditions that we experience-nociceptive, inflammatory and physiologically dysfunction, such as neuropathic pain and its modulation and feedback systems. Moreover, the complete mechanism of conduction is compiled within this article, elucidating understandings from various researches and breakthroughs.

    Rheumatoid arthritis is a chronic inflammatory disorder of polyarticular tissues, characterised by progressive synovitis. Its prolonged treatment imparts a huge burden on the healthcare system and results in toxicity, which necessitates the search for safe, efficacious and cost-effective therapies. Diospyros malabarica (Desr.) Kostel is traditionally used for anti-inflammatory purposes; however, to the best of our knowledge, there is no detailed study reporting the in vivo anti-inflammatory potential of this plant. Therefore, in the current study, the methanol extract of D. malabarica (Desr.) Kostel fruit (mDMF) was evaluated for its antioxidant, anti-inflammatory and anti-arthritic potentials, along with its underlying mechanisms. The antioxidant activity was evaluated by DPPH assay. Total phenolic and flavonoid contents were estimated via colorimetric and high-performance liquid chromatography (HPLC) methods. Different doses (250, 500 and 750 mg/kg) of mDMF were used to evaluate the anti-inflammatory and anti-arthritis actions in acute inflammatory (carrageenan and histamine-induced paw oedema) and Freund's complete adjuvant (FCA)-induced arthritis rat models. Levels of various pro- and anti-inflammatory biomarkers were estimated using ELISA and RT-PCR techniques. Paw samples were used for different histopathological and radiographic studies. Qualitative phytochemical and HPLC analyses indicated the presence of various polyphenolic compounds in mDMF, which exhibited marked antioxidant activity in the DPPH assay. mDMF showed time-dependent anti-inflammatory and anti-arthritic effects in in vivo models. ELISA assay data showed significant (p

    Ishak NIM, Mohamed S, Madzuki IN, Mustapha NM, Esa NM
    Naunyn Schmiedebergs Arch Pharmacol, 2021 09;394(9):1907-1915.
    PMID: 34009457 DOI: 10.1007/s00210-021-02101-6
    Inflammation and compromised immune responses often increase colorectal cancer (CRC) risk. The immune-modulating effects of limonin on carcinogen/inflammation-induced colorectal cancer (CRC) were studied in mice. Male Balb/c mice were randomly assorted into three groups (n = 6): healthy control, non-treated CRC-induced (azoxymethane/dextran-sulfate-sodium AOM/DSS) control, and CRC-induced + 50 mg limonin/kg body weight. The CRC developments were monitored via macroscopic, histopathological, ELISA, and mRNA expression analyses. Limonin downregulated inflammation (TNF-α, tumor necrosis factor-α), enhanced the adaptive immune responses (CD8, CD4, and CD19), and upregulated antioxidant defense (Nrf2, SOD2) mRNA expressions. Limonin reduced serum malondialdehyde (MDA, lipid peroxidation biomarker), prostaglandin E2, and histopathology inflammation scores, while increasing reduced glutathione (GSH) in CRC-induced mice. Limonin significantly (p

    Tumpang MA, Ramli NA, Hussain Z
    Curr Drug Targets, 2018;19(6):674-700.
    PMID: 28914203 DOI: 10.2174/1389450118666170913162147
    BACKGROUND: Phytomedicines have been well-accepted alternative complementary therapies for the treatment of a wide range of acute and chronic skin inflammatory diseases including chronic herpes, prurigo, psoriasis, and atopic dermatitis (AD). A plethora of in vitro and in vivo studies have evidenced the therapeutic viability of phytomedicines, polyherbal formulations, plant-based materials and their decoctions for the treatment of mild-to-severe AD.

    OBJECTIVE: This review was aimed to summarize and critically discuss the convincing evidence for the therapeutic effectiveness of phytomedicines for the treatment of AD and explore their anti-AD efficacy.

    RESULTS: The critical analysis of a wide algorithm of herbal medicines revealed that their remarkable anti-AD efficacy is attributed to their potential of reducing erythema intensity, oedema, inflammation, transepidermal water loss (TEWL) and a remarkable suppression of mRNA expression of ADassociated inflammatory biomarkers including histamine, immunoglobulin (Ig)-E, prostaglandins, mast cells infiltration and production of cytokines and chemokines in the serum and skin biopsies.

    CONCLUSION: In conclusion, herbal medicines hold great promise as complementary and alternative therapies for the treatment of mild-to-moderate AD when used as monotherapy and for the treatment of moderate-to-severe AD when used in conjunction with other pharmacological agents.

    Riyahi N, Tohit ERM, Thambiah SC, Ibrahim Z
    Asia Pac J Clin Nutr, 2017 12 10;27(1):182-188.
    PMID: 29222897 DOI: 10.6133/apjcn.032017.01
    BACKGROUND AND OBJECTIVES: Recent studies have reported that obesity is associated with platelet activation and systemic inflammation. Malaysia has the highest prevalence of obesity, hence, this research is performed to evaluate the development of low-grade inflammation and platelet activation, measured using soluble CD40 ligand (sCD40L) and soluble P-selectin (sP-sel), and to determine their association with obesity. In addition, we assessed the mean platelet volume (MPV) and platelet count (PLT), which are novel parameters consistently associated with obesity.

    METHODS AND STUDY DESIGN: A cross-sectional study was conducted on 112 healthy men and women from 3 main ethnic group (Malay, Chinese, and Indian) who were aged 18-60 years. The participants were categorized into normal body mass index (BMI), overweight and obese groups according to WHO criteria for BMI in Asian populations (18.5 kg/m2

  6. Fulltext Palmatine as an Agent Against Metabolic Syndrome and Its Related Complications: A Review
    Ekeuku SO, Pang KL, Chin KY
    Drug Des Devel Ther, 2020;14:4963-4974.
    PMID: 33235437 DOI: 10.2147/DDDT.S280520
    Palmatine is a naturally occurring isoquinoline alkaloid with various pharmacological properties. Given its antioxidant and anti-inflammatory properties, palmatine may be able to impede the effects of metabolic syndrome (MetS) and its related diseases triggered by inflammation and oxidative stress. This review summarises the existing literature about the effects of palmatine supplementation on MetS and its complications. The evidence shows that palmatine could protect against MetS, and cardiovascular diseases, osteoporosis and osteoarthritis, which might be associated with MetS. These protective effects are mediated by the antioxidant and anti-inflammatory properties of palmatine. Although preclinical experiments have demonstrated the efficacy of palmatine against MetS and its related diseases, no human clinical trials have been performed to validate these effects. This research gap should be bridged to validate the efficacy and safety of palmatine supplementation in protecting humans against MetS and its related diseases.

  7. Fulltext Plasma polyphenols associated with lower high-sensitivity C-reactive protein concentrations: a cross-sectional study within the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort
    Harms LM, Scalbert A, Zamora-Ros R, Rinaldi S, Jenab M, Murphy N, et al.
    Br J Nutr, 2020 Jan 28;123(2):198-208.
    PMID: 31583990 DOI: 10.1017/S0007114519002538
    Experimental studies have reported on the anti-inflammatory properties of polyphenols. However, results from epidemiological investigations have been inconsistent and especially studies using biomarkers for assessment of polyphenol intake have been scant. We aimed to characterise the association between plasma concentrations of thirty-five polyphenol compounds and low-grade systemic inflammation state as measured by high-sensitivity C-reactive protein (hsCRP). A cross-sectional data analysis was performed based on 315 participants in the European Prospective Investigation into Cancer and Nutrition cohort with available measurements of plasma polyphenols and hsCRP. In logistic regression analysis, the OR and 95 % CI of elevated serum hsCRP (>3 mg/l) were calculated within quartiles and per standard deviation higher level of plasma polyphenol concentrations. In a multivariable-adjusted model, the sum of plasma concentrations of all polyphenols measured (per standard deviation) was associated with 29 (95 % CI 50, 1) % lower odds of elevated hsCRP. In the class of flavonoids, daidzein was inversely associated with elevated hsCRP (OR 0·66, 95 % CI 0·46, 0·96). Among phenolic acids, statistically significant associations were observed for 3,5-dihydroxyphenylpropionic acid (OR 0·58, 95 % CI 0·39, 0·86), 3,4-dihydroxyphenylpropionic acid (OR 0·63, 95 % CI 0·46, 0·87), ferulic acid (OR 0·65, 95 % CI 0·44, 0·96) and caffeic acid (OR 0·69, 95 % CI 0·51, 0·93). The odds of elevated hsCRP were significantly reduced for hydroxytyrosol (OR 0·67, 95 % CI 0·48, 0·93). The present study showed that polyphenol biomarkers are associated with lower odds of elevated hsCRP. Whether diet rich in bioactive polyphenol compounds could be an effective strategy to prevent or modulate deleterious health effects of inflammation should be addressed by further well-powered longitudinal studies.

    Chew BH, Shariff-Ghazali S, Fernandez A
    World J Diabetes, 2014 Dec 15;5(6):796-808.
    PMID: 25512782 DOI: 10.4239/wjd.v5.i6.796
    Patients with diabetes mellitus (DM) need psychological support throughout their life span from the time of diagnosis. The psychological make-up of the patients with DM play a central role in self-management behaviors. Without patient's adherence to the effective therapies, there would be persistent sub-optimal control of diseases, increase diabetes-related complications, causing deterioration in quality of life, resulting in increased healthcare utilization and burden on healthcare systems. However, provision of psychosocial support is generally inadequate due to its challenging nature of needs and demands on the healthcare systems. This review article examines patient's psychological aspects in general, elaborates in particular about emotion effects on health, and emotion in relation to other psychological domains such as cognition, self-regulation, self-efficacy and behavior. Some descriptions are also provided on willpower, resilience, illness perception and proactive coping in relating execution of new behaviors, coping with future-oriented thinking and influences of illness perception on health-related behaviors. These psychological aspects are further discussed in relation to DM and interventions for patients with DM. Equipped with the understanding of the pertinent nature of psychology in patients with DM; and knowing the links between the psychological disorders, inflammation and cardiovascular outcomes would hopefully encourages healthcare professionals in giving due attention to the psychological needs of patients with DM.

  9. Molecular mechanisms underlying the potential antiobesity-related diseases effect of cocoa polyphenols
    Ali F, Ismail A, Kersten S
    Mol Nutr Food Res, 2014 Jan;58(1):33-48.
    PMID: 24259381 DOI: 10.1002/mnfr.201300277
    Obesity and related metabolic diseases (e.g., type 2 diabetes, cardiovascular diseases, and hypertension) are the most prevailing nutrition-related issues in the world. An emerging feature of obesity is their relationship with chronic inflammation that begins in white adipose tissue and eventually becomes systemic. One potential dietary strategy to reduce glucose intolerance and inflammation is consumption of polyphenol-rich cocoa-like cocoa or their by-products. In vitro as well as in vivo data indicate that cocoa polyphenols (CPs) may exhibit antioxidant and anti-inflammatory properties. Polyphenols commonly found in cocoa have been reported to regulate lipid metabolism via inducing metabolic gene expression or activating transcription factors that regulate the expression of numerous genes, many of which play an important role in energy metabolism. Currently, several molecular targets (e.g., nuclear factor Kappa B, activated protein-1, peroxisome proliferator-activated receptors, liver X receptors, and adiponectin gene) have been identified, which may explain potential beneficial obesity-associated diseases effects of CPs. Further studies have been performed regarding the protective effects of CPs against metabolic diseases by suppressing transcription factors that antagonize lipid accumulation. Thus, polyphenols-rich cocoa products may diminish obesity-mediated metabolic diseases by multiple mechanisms, thereby attenuating chronic inflammation.

    Wen CT, Hussein SZ, Abdullah S, Karim NA, Makpol S, Mohd Yusof YA
    Asian Pac J Cancer Prev, 2012;13(4):1605-10.
    PMID: 22799375
    Gelam and Nenas monofloral honeys were investigated in this study for their chemopreventive effects against HT 29 colon cancer cells. MTS (3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H- tetrazolim) assays showed more effective inhibition of colon cancer cells proliferation by Gelam honey with IC₅₀ values of 39.0 mg/ml and 85.5 mg/ml respectively after 24 hours of treatment. Alkali comet assays revealed both honeys increased DNA damage significantly in a dose dependent manner. In addition, annexin V-FITC/PI flow cytometry demonstrated that at IC₅₀ concentrations and above, both Gelam and Nenas honeys induced apoptosis significantlyat values higher than for necrosis (p<0.05). Measurement of prostaglandin E₂ (PGE₂) confirmed that Gelam and Nenas honeys reduced its production in H₂O₂ inflammation-induced colon cancer cells. In conclusion, our study indicated and confirmed that both Gelam and Nenas honeys are capable of suppressing the growth of HT 29 colon cancer cells by inducing apoptosis and suppressing inflammation.

  11. Fulltext Subcutaneous administration of tramadol after elective surgery is as effective as intravenous administration in relieving acute pain and inflammation in dogs
    Buhari S, Hashim K, Yong Meng G, Mustapha NM, Gan SH
    ScientificWorldJournal, 2012;2012:564939.
    PMID: 22778699 DOI: 10.1100/2012/564939
    Subcutaneous (SC) administration of tramadol was compared with intravenous (IV) administration to evaluate analgesia following canine ovariohysterectomy (OHE). Healthy female dogs (n = 12) between 1 and 3 years of age (1.95 ± 0.65 years), weighing between 10.5 and 17.1 kg (13.12 ± 1.95 kg), were used. Pain was assessed at baseline before surgery and then hourly for 8 hr after surgery. Tramadol was administered both SC and IV at a dose of 3 mg/kg and provided significant postoperative analgesia, as indicated by analgesiometry, β-endorphin levels, and interleukin 6 (IL-6) levels. The respiratory rates and rectal temperatures remained normal and were not significantly different between or within the groups. A significant increase in heart rate was observed at 4 hr for dogs in both groups relative to the baseline, but there was no significant difference in heart rates between the groups at any time point. A significant decrease in mechanical pain threshold was observed within each group after surgery, but both groups responded similarly, suggesting that SC administration of tramadol is as effective as IV administration. Increased serum levels of both IL-6 and β-endorphin 3 hr postoperatively further indicate that both routes of administration achieve similar pain control. Thus, the relative analgesic efficacy of SC tramadol is comparable to that of IV administration and can be used to achieve similar effects for postsurgical pain management in dogs undergoing OHE.

    Zamri Z, Harunarashid, Das S, Ramzisham AR
    Clin Ter, 2010;161(5):457-8.
    PMID: 20964103
    Ureteritis cystica is a rare, benign, proliferative condition. We report the case of a 51-year-old female who complained of dysuria and frequency for the last 10 years. The symptoms, however, increased in severity and frequency over the past one year. Urine culture and sensitivity showed presence of Escherichia Coli which was sensitive to augmentin and ciproflaxocin. The urinary tract ultrasonography and intravenous urography revealed bladder diverticula with multiple small, smooth well defects with sharp borders that protruded into the lumen along the proximal and mid left ureter. This finding was later confirmed by retrograde pyelogram. She was treated and currently is on long term antibiotic therapy. The diagnostic features and management of ureteritis cystic is being discussed in detail.

  14. Review: the Multiple Roles of Monocytic Microparticles
    Halim AT, Ariffin NA, Azlan M
    Inflammation, 2016 Aug;39(4):1277-84.
    PMID: 27216803 DOI: 10.1007/s10753-016-0381-8
    Monocytic microparticles (mMP) are microparticles derived from human monocytes either under in vivo or in vitro conditions. The size of mMP is between 0.1 and 1.0 μm. Apart from the size range, mMPs are also identified based on phosphatidylserine and CD14 expression on their surface, though this is not always the case. Monocytic MP are critical players in inflammation, endothelial cell function, and blood coagulation. They exhibit dual function by either helping the progression of such conditions or limiting it, depending on certain factors. Furthermore, the numbers of mMP are elevated in some autoimmune diseases, infectious diseases, and metabolic disorders. However, it is unknown whether mMP play an active role in these diseases or are simply biomarkers. The mechanism of mMP modulation is yet to be identified. In this review, we highlight the mechanism of mMP formation and the roles that they play in inflammation, blood coagulation, and different disease settings.

  15. Fulltext It is time to change the way we manage mild asthma: an update in GINA 2019
    Muneswarao J, Hassali MA, Ibrahim B, Saini B, Ali IAH, Verma AK
    Respir Res, 2019 Aug 14;20(1):183.
    PMID: 31412856 DOI: 10.1186/s12931-019-1159-y
    Asthma is a heterogeneous lung disease, usually characterised by chronic airway inflammation. Although evidence-based treatments are available in most countries, asthma control remains suboptimal, and asthma-related deaths continue to be an ongoing concern. Generally, it is believed that between 50 to 75% of patients with asthma can be considered as having mild asthma.Previous versions of Global Initiative for Asthma (GINA) suggested that mild asthma in adults can be well managed with either reliever medications, for example, short-acting beta2 agonists (SABA) alone or with the additional use of controllers such as regular low-dose inhaled corticosteroids (ICS). Given the low frequency or non-bothersome nature of symptoms in mild asthma, patients' adherence towards their controller medications, especially to ICS is usually not satisfactory. Such patients often rely on SABA alone to relieve symptoms, which may contribute to SABA over-reliance. Overuse of relievers such as SABAs has been associated with poor asthma outcomes, such as exacerbations and even deaths. The new GINA 2019 asthma treatment recommendations represent significant shifts in asthma management at Steps 1 and 2 of the 5 treatment steps. The report acknowledges an emerging body of evidence suggesting the non-safety of SABAs overuse in the absence of concomitant controller medications, therefore does not support SABA-only therapy in mild asthma and has included new off-label recommendations such as symptom-driven (as-needed) low dose ICS-formoterol and "low dose ICS taken whenever SABA is taken".The GINA 2019 report highlights significant updates in mild asthma management and these recommendations represent a clear deviation from decades of clinical practice mandating the use of symptom-driven SABA treatment alone in those with mild asthma. While the new inclusions of strategies such as symptom-driven (as-needed) ICS-formoterol and "ICS taken whenever SABA is taken" are based on several key trials, data in this context are still only emergent data, with clear superiority of as needed ICS-formoterol combinations over maintenance ICS regimens yet to be established for valid endpoints. Nevertheless, current and emerging data position the clinical asthma realm at a watershed moment with imminent changes for the way we manage mild asthma likely in going forward.

  16. Role of the CXCR4-SDF1-HMGB1 pathway in the directional migration of cells and regeneration of affected organs
    Haque N, Fareez IM, Fong LF, Mandal C, Abu Kasim NH, Kacharaju KR, et al.
    World J Stem Cells, 2020 Sep 26;12(9):938-951.
    PMID: 33033556 DOI: 10.4252/wjsc.v12.i9.938
    In recent years, several studies have reported positive outcomes of cell-based therapies despite insufficient engraftment of transplanted cells. These findings have created a huge interest in the regenerative potential of paracrine factors released from transplanted stem or progenitor cells. Interestingly, this notion has also led scientists to question the role of proteins in the secretome produced by cells, tissues or organisms under certain conditions or at a particular time of regenerative therapy. Further studies have revealed that the secretomes derived from different cell types contain paracrine factors that could help to prevent apoptosis and induce proliferation of cells residing within the tissues of affected organs. This could also facilitate the migration of immune, progenitor and stem cells within the body to the site of inflammation. Of these different paracrine factors present within the secretome, researchers have given proper consideration to stromal cell-derived factor-1 (SDF1) that plays a vital role in tissue-specific migration of the cells needed for regeneration. Recently researchers recognized that SDF1 could facilitate site-specific migration of cells by regulating SDF1-CXCR4 and/or HMGB1-SDF1-CXCR4 pathways which is vital for tissue regeneration. Hence in this study, we have attempted to describe the role of different types of cells within the body in facilitating regeneration while emphasizing the HMGB1-SDF1-CXCR4 pathway that orchestrates the migration of cells to the site where regeneration is needed.

    PMID: 22017767 DOI: 10.1111/j.1440-1681.2011.05633.x
    1. Andrographis paniculata (Burm. f) Nees, commonly known as 'king of bitters', is a herbaceous plant belonging to the Family Acanthaceae. It has been widely used for centuries in Asian countries like China, India, Thailand and Malaysia for the treatment of sore throat, flu and upper respiratory tract infections. 2. Andrographolide, 14-deoxy-11,12-didehydroandrographolide and neoandrographolide are examples of the major labdane diterpenoids isolated from A. paniculata. These bioactive molecules have exhibited varying degrees of anti-inflammatory and anticancer activities in both in vitro and in vivo experimental models of inflammation and cancer. 3. Extensive libraries of andrographolide analogues have been synthesised mainly by modifying the α,β-unsaturated γ-butyrolactone moiety, the two double bonds Δ(8,(17)) and Δ(12,(13)) and the three hydroxyls at C-3 (secondary), C-14 (allylic) and C-19 (primary). Many of these synthetic analogues exhibit superior anticancer activity over the naturally occurring andrographolides. 4. Andrographolide and its derivatives have been shown to have anti-inflammatory effects in experimental models of asthma, stroke and arthritis, as well as in patients with upper respiratory tract infections. Andrographolide reduces the production of cytokines, chemokines, adhesion molecules, nitric oxide and lipid mediators, probably via inhibition of the nuclear factor (NF)-κB signalling pathway. 5. The anticancer mechanisms for andrographolide include inhibition of Janus tyrosine kinases-signal transducers and activators of transcription, phosphatidylinositol 3-kinase and NF-κB signalling pathways, suppression of heat shock protein 90, cyclins and cyclin-dependent kinases, metalloproteinases and growth factors, and the induction of tumour suppressor proteins p53 and p21, leading to inhibition of cancer cell proliferation, survival, metastasis and angiogenesis. 6. Andrographolide drug discovery is a promising strategy for the development of a novel class of anti-inflammatory and anticancer drugs.

    World J Mens Health, 2021 Apr;39(2):195-207.
    PMID: 32648373 DOI: 10.5534/wjmh.200014
    Prostate cancer has become the second leading cancer in men worldwide. Androgen plays an important role in normal functioning, development, and differentiation of the prostate, and thus is considered to be the most powerful candidate that mediates reactive oxygen species (ROS) balance in the prostate. The elevation of ROS has been associated with the progression and development of this disease. Conventional therapy has shown a high cure rate in patients with localized prostate cancer. Despite the patients respond favorably initially, this therapy fails to response in the advanced stage of the diseases even in the absence of androgens. Indeed, the onset and progression of prostate cancer could be prevented by changing dietary habits. Much information indicates that oxidative stress and prostate cancer can be modulated by dietary components rich in antioxidants. While there is substantial evidence to suggest an association between prostate cancer risk and ROS-mediated oxidative stress; therefore, the interactions and mechanisms of this phenomenon are worth to discuss further. This review aimed to discuss the mechanisms of action of oxidative stress involved in the progression of prostate cancer.
