The cluster sampling was used.Information was collected by interviewing and using a standardized validated questionnaire. Severity of mastalgia was assessed through using visual analog scaling. Data processing and statistical analysis were performed by using SPSS 19.0.Results: The results revealed that majority of women(60.0%) experienced cyclical mastalgia.Out of these, 22.5% and 37.5% were mild and moderate-to-severe mastalgia, respectively. No association was revealed in experience of depression and anxiety in mastalgia group. In a multivariable logistic regression model, the increasing age, age of marriage, history of abortion and history of premenstrual syndrome were main determinants of mastalgia, while use of oral contraceptive and regular exercise was associated with lower incidence of mastalgia.Conclusions: Most of women with breast discomfort suffered cyclical mastalgia which severity can be determined by advanced age, age of marriage, history of abortion and history of premenstrual syndrome, but inversely by oral contraceptive use and exercise activity.展开更多

They are associated with a low incidence and comprise 0.3% - 0.9% of all breast tumors. Recurrence occurs in about 20% of cases, and malignant PTs exhibit a higher rate of early recurrence than benign ones. The transformation from malignant to benign PTs is extremely rare. Here, we presented the case of a 29-year-old woman diagnosed with a malignant PT that transformed into a benign Within six months after excisional surgery. Materials and Methods: This is a case report. Results: A 29-year-old woman presented to our hospital with left breast enlargement, which was not accompanied by pain or discharge. An ultrasound revealed a heterogeneous, solid mass. She underwent surgical excision of the mass, which was later diagnosed as a malignant PT pathology. After the surgery, the patient was monitored through regular follow-up visits, during which all examinations were normal. However, six months later, a new mass was felt in the same area. She underwent another surgical excision, and this mass was diagnosed as a benign PT. Conclusion: Malignant PTs should be taken into account for patients who present with rapidly growing breast masses. Timely diagnosis and treatment are vital because they significantly affect the prognosis of these cases. A thorough evaluation, including ultrasound and biopsy, is necessary to prevent misdiagnosis. The definitive diagnosis of PTs can only be established through biopsy. Effective treatment, which involves surgical excision with clear margins, is crucial for preventing recurrence and potentially life-threatening consequences.展开更多

Vertebral artery injury is a low-frequency but high-mortality injury. We aim to report evidence of delayed onset of vascular symptoms following penetrating trauma in the neck. Materials and Methods: A case report. Results: A 19-year-old boy was referred to our hospital and complained of a mass in the right part of his neck (right mandibular angle). He gave a history of penetrating trauma to his neck 2 months ago. The mass was expanding during these 2 months and doesn’t respond to antibiotic therapy. In the examination, 3 × 3 cm, firm, nonmobile, and without tenderness and pain mass was palpated in the second level of his neck. Doctors ordered a Doppler sonography in the hospital where a yin-yang pattern was reported. A 36 × 43 × 40 mm heterogeneous, solid, and hypodense area close to C1-C2-C3 with vascular flow was discovered in the right submandibular area after computed tomography (CT)-angiography. The patient was referred to an interventional neurologist for angiography and due to the lack of flow at the distal of the V3 segment, he decided to sacrifice this artery by two coils. Conclusion: Penetrating neck injuries are usually asymptomatic, but these injuries are often accompanied by hemorrhage, neurological symptoms, dysphagia, odynophagia, and windpipe. Penetrating lesions of the vertebral artery are rare and very difficult to diagnose. Also, these lesions are challenging for surgeons due to complex anatomy and difficult surgical exposure. So, endovascular treatment was used to treat the patient.展开更多

Studies have also shown that miRNA-183 family, in different pathways, affects the neurosensory development, maintenance, survival and function. In addition, it has potential neuroprotective effects in response to neurosensory destructive stimulations. miRNA-96 mutation causes hereditary deafness in humans and mice, and therefore affects the inner ear activity and its maintenance. Certain roles have been identified for mi R-96 in the maintenance and function of the inner ear. The comparison of the target genes of family-183 in transcriptomes of newborn and adult hair cells shows that hundreds of target genes in this family may affect development and maintenance of the ears. Identifying the genes that are regulated by miRNA-183 family provides researchers with important information about the complex development and environmental regulation of the inner ear, and can offer new approaches to the maintenance and regeneration of hair cells and auditory nerve.展开更多

METHODS: A total of 2292 (1376 female, aged 18-75 year), were selected by systematic clustered random sampling from the cities and villages of Gonbad and Kalaleh in Golestan Province and invited to participate in the study. A comprehensive history regarding alcohol drinking and medication was taken. Body mass index (BMI), viral markers and ALT levels were measured. If ALT level was ≥ 40 U/L, it was rechecked twice within 6 mo. Those with ≥ 2 times elevation of ALT were considered as having persistently elevated ALT level. Non-alcoholic fatty liver disease (NAFLD) was diagnosed based on evidence of fatty liver upon sonography and excluding other etiology. RESULTS: A total of 2049 (1351 female) patients participated in the study, 162 (7.9%) had elevated ALT level at the first measurement. Persistently elevated ALT level was detected in 64 (3.1%) participants, with51 (79.6%) with no obvious etiology, six (9.3%) with Hepatitis B, four (6.2%) with Hepatitis C virus (HCV) infection and three (4.6%) with alcoholic hepatitis. The prevalence of NAFLD and alcoholic hepatitis was 2.04% (42 patients) and 0.1% (three), respectively. There was correlation between NAFLD and male gender, overweight, diabetes and living in an urban area [odds ratio = 3.03 (95% CI: 1.6-5.72), 4.21 (95% CI: 1.83-9.68), 2.86 (95% CI: 1.05-7.79) and 2.04 (95% CI: 1.00-4.16) respectively]. CONCLUSION: NAFLD is the most common cause of persistently elevated serum ALT level among the general population of Iran.展开更多

HCV c...Hepatocellular carcinoma(HCC) is the fifth most common cancer, and hepatitis C virus(HCV) infection plays a major role in HCC development. The molecular mechanisms by which HCV infection leads to HCC are varied. HCV core protein is an important risk factor in HCV-associated liver pathogenesis and can modulate several signaling pathways involved in cell cycle regulation, cell growth promotion, cell proliferation, apoptosis, oxidative stress and lipid metabolism. The dysregulation of signaling pathways such as transforming growth factor β(TGF-β), vascular endothelial growth factor(VEGF), Wnt/β-catenin(WNT), cyclooxygenase-2(COX-2) and peroxisome proliferator-activated receptor α(PPARα) by HCV core protein is implicated in the development of HCC. Therefore, it has been suggested that this protein be considered a favorable target for further studies in the development of HCC. In addition, considering the axial role of these signaling pathways in HCC, they are considered druggable targets for cancer therapy. Therefore, using strategies to limit the dysregulation effects of core protein on these signaling pathways seems necessary to prevent HCV-related HCC.展开更多

This study aimed to identify the association of HLA class II alleles with DPN in type 2 diabetes （T2D） patients. Totally 106 T2D patients, 49 with DPN and 57 without DPN, and 100 ethnic-matched healthy controls were analyzed. Both groups of the patients were matched based on sex, age, body mass index （BMI） and duration of T2D. Polyneuropathy was diagnosed using electrodiagnostic methods. HLA-DRB1 and DQB1 genotyping was performed in all subjects by the polymerase chain reaction with sequence-specific primers （PCR-SSP） method. T2D patients with DPN showed higher frequencies of HLA-DRB1＊10 and DRB1＊12 alleles compared to control group （P = 0.04）. HLA-DQB1＊02 allele and HLA-DRB1＊07-DQB1＊02 haplotype were associated with a decreased risk for developing DPN in T2D patients （P = 0.02 and P = 0.05 respectively）. Also, patients with severe neuropathy showed higher frequencies of DRB1＊07 （P = 0.003） and DQB1＊02 （P = 0.02） alleles than those with mild-to-moderate form of neuropathy. The distribution of DRB 1 and DQB 1 alleles and haplotypes were not statistically different between all patients and healthy controls. Our findings implicate a possible protective role of HLA-DQB1＊02 allele and HLA-DRB1＊07-DQB1＊02 haplotype against development of peripheral neuropathy in T2D patients. Therefore, variations in HLA genotypes might be used as genetic markers for prediction and potentially management of neuropathy in T2D patients.展开更多

文摘Objectives:To investigate the parenting stress,care burden,and coping styles in mothers of autistic children during the pandemic of COVID-19.The outbreak of COVID-19 and the closure of education and care centers for these children may affect stress,care burden,and adaptation of these mothers.Methods:This study was a cross-sectional research.A total of 110 mothers completed questionnaires.Data were analyzed by descriptive statistics(frequency,percentage,mean,and standard deviation),independent t-test,ANOVA,and multiple linear regressions.Results:Findings showed that parenting stress has a strong and direct correlation with caring burden(P<0.001,r=0.95),and a strong and indirect correlation with coping styles(P<0.001,r=−0.91).Variables of caring burden,coping strategies,mother’s age,mother’s job,mother’s education,number of autistic children,economic status,children’s age,and functional level of autism in children can predict 72.21%of the variance in parenting stress in these mothers.Conclusions:In the present study,parenting stress of mothers of autistic children was reported to be high during the COVID-19 pandemic.Based on the findings of this study,it can be concluded that pediatric nurses and health policymakers should provide a suitable educational and supportive environment for mothers of autistic children to enhance the coping level of these mothers and consequently reduce their parenting stress and care burden.
文摘BACKGROUND Otitis media with effusion(OME),glue ear,serous otitis media,or secretory otitis media is a common paediatric condition.Two widely used surgical interventions for OME are myringotomy alone and myringotomy with tympanostomy tube.While both procedures aim to improve hearing outcomes,the efficacy of these approaches has been a subject of ongoing research and debate.AIM To compare the efficacy of myringotomy alone and myringotomy with tympa-nostomy tube.METHODS In this comparative study,66 patients diagnosed as OME meeting the inclusion criteria were selected via ear,nose and throat department.They were divided into two groups randomly,each of 33 patients.In the first group(Group A)myrin-gotomy alone was performed while in the second group(Group B)myringotomy with tympanostomy tube placement was performed.We observed hearing outcome by pure tone audiogram(PTA)pre operatively.Patients were followed up and re-assessed in outdoor patient department at 4th week postoperatively again by PTA.RESULTS The mean age of the patients in Group A was 10.96±2.76 SD but the mean age of the patients in Group B was 10.22±2.73 SD(P=0.1056).In Group A,males were 63.6%and females were 36.3%.Also in Group B,males were 63.6%and females were 36.3%(P=1.0).In group A,post operative hearing gain using pure tone audiometry at one month was 20.45±3.78 SD while in group B,post operative hearing gain using pure tone audiometry at one month was 23.84±3.69 SD(P=0.00005).However,ear discharge was noted in 3.03%cases in group A and 15.15%cases in group B(P=0.035).By applying independent t-test,the P<0.05 indicated that there is a significant association between Group B and hearing improvement at 4th week.CONCLUSION Our study concluded that myringotomy with tympanostomy tube seems to have better hearing results than myringotomy alone in treatment of OME.
文摘Glaucoma,an irreversible optic neuropathy,primarily affects retinal ganglion cells(RGC)and causes vision loss and blindness.The damage to RGCs in glaucoma occurs by various mechanisms,including elevated intraocular pressure,oxidative stress,inflammation,and other neurodegenerative processes.As the disease progresses,the loss of RGCs leads to vision loss.Therefore,protecting RGCs from damage and promoting their survival are important goals in managing glaucoma.In this regard,resveratrol(RES),a polyphenolic phytoalexin,exerts antioxidant effects and slows down the evolution and progression of glaucoma.The present review shows that RES plays a protective role in RGCs in cases of ischemic injury and hypoxia as well as in ErbB2 protein expression in the retina.Additionally,RES plays protective roles in RGCs by promoting cell growth,reducing apoptosis,and decreasing oxidative stress in H_(2)O_(2)-exposed RGCs.RES was also found to inhibit oxidative stress damage in RGCs and suppress the activation of mitogen-activated protein kinase signaling pathways.RES could alleviate retinal function impairment by suppressing the hypoxia-i nducible factor-1 alpha/vascular endothelial growth factor and p38/p53 axes while stimulating the PI3K/Akt pathway.Therefore,RES might exert potential therapeutic effects for managing glaucoma by protecting RGCs from damage and promoting their survival.
文摘Noise is one of the environmental factors with mental and physical effects.The workload is also the multiple mental and physical demands of the task.Therefore,his study investigated the relationship between noise exposure and mood states at different levels of workload.The study recruited 50 workers from the manufacturing sector(blue-collar workers)as the exposed group and 50 workers from the office sector(white-collar workers)as the control group.Their occupational noise exposure was measured by dosimetry.The Stress-Arousal Checklist(SACL)and the NASA Task Load Index(NASA-TLX)were used to measure mood and workload,respectively.The equivalent noise exposure level of the exposed group at high and very high workload levels was 85 and 87 dBA,respectively.The mean mood score of the exposed group was 76 at very high workload.The correlation coefficient between noise exposure level and mood state based on workload levels ranged from 0.3 at medium workload to 0.57 at very high workload.Noise exposure at high workload levels can increase its adverse effects,so controlling and optimizing the multiple demands of the task in the workplace can be used as a privative measure to reduce the adverse effects of noise.
文摘Background:Breast cancer(BC)continues to be a significant global health issue,with a rising number of cases requiring ongoing research and innovation in treatment strategies.Curcumin(CUR),a natural compound derived from Curcuma longa,and similar compounds have shown potential in targeting the STAT3 signaling pathway,which plays a crucial role in BC progression.Aims:The aim of this study was to investigate the effects of curcumin and its analogues on BC based on cellular and molecular mechanisms.Materials&Methods:The literature search conducted for this study involved utilizing the Scopus,ScienceDirect,PubMed,and Google Scholar databases in order to identify pertinent articles.Results:This narrative review explores the potential of CUR and similar compounds in inhibiting STAT3 activation,thereby suppressing the proliferation of cancer cells,inducing apoptosis,and inhibiting metastasis.The review demonstrates that CUR directly inhibits the phosphorylation of STAT3,preventing its movement into the nucleus and its ability to bind to DNA,thereby hindering the survival and proliferation of cancer cells.CUR also enhances the effectiveness of other therapeutic agents and modulates the tumor microenvironment by affecting tumor-associated macrophages(TAMs).CUR analogues,such as hydrazinocurcumin(HC),FLLL11,FLLL12,and GOY030,show improved bioavailability and potency in inhibiting STAT3,resulting in reduced cell proliferation and increased apoptosis.Conclusion:CUR and its analogues hold promise as effective adjuvant treatments for BC by targeting the STAT3 signaling pathway.These compounds provide new insights into the mechanisms of action of CUR and its potential to enhance the effectiveness of BC therapies.
文摘Objective: Phyllodes tumors (PTs) are rare, distinctive fibroepithelial neoplasms. They are associated with a low incidence and comprise 0.3% - 0.9% of all breast tumors. Recurrence occurs in about 20% of cases, and malignant PTs exhibit a higher rate of early recurrence than benign ones. The transformation from malignant to benign PTs is extremely rare. Here, we presented the case of a 29-year-old woman diagnosed with a malignant PT that transformed into a benign Within six months after excisional surgery. Materials and Methods: This is a case report. Results: A 29-year-old woman presented to our hospital with left breast enlargement, which was not accompanied by pain or discharge. An ultrasound revealed a heterogeneous, solid mass. She underwent surgical excision of the mass, which was later diagnosed as a malignant PT pathology. After the surgery, the patient was monitored through regular follow-up visits, during which all examinations were normal. However, six months later, a new mass was felt in the same area. She underwent another surgical excision, and this mass was diagnosed as a benign PT. Conclusion: Malignant PTs should be taken into account for patients who present with rapidly growing breast masses. Timely diagnosis and treatment are vital because they significantly affect the prognosis of these cases. A thorough evaluation, including ultrasound and biopsy, is necessary to prevent misdiagnosis. The definitive diagnosis of PTs can only be established through biopsy. Effective treatment, which involves surgical excision with clear margins, is crucial for preventing recurrence and potentially life-threatening consequences.
文摘Objective: Vascular injuries usually present immediately after the penetration, but the delayed onset of vascular symptoms caused by vessel dissection or aneurysm after a traumatic event is extremely rare. Vertebral artery injury is a low-frequency but high-mortality injury. We aim to report evidence of delayed onset of vascular symptoms following penetrating trauma in the neck. Materials and Methods: A case report. Results: A 19-year-old boy was referred to our hospital and complained of a mass in the right part of his neck (right mandibular angle). He gave a history of penetrating trauma to his neck 2 months ago. The mass was expanding during these 2 months and doesn’t respond to antibiotic therapy. In the examination, 3 × 3 cm, firm, nonmobile, and without tenderness and pain mass was palpated in the second level of his neck. Doctors ordered a Doppler sonography in the hospital where a yin-yang pattern was reported. A 36 × 43 × 40 mm heterogeneous, solid, and hypodense area close to C1-C2-C3 with vascular flow was discovered in the right submandibular area after computed tomography (CT)-angiography. The patient was referred to an interventional neurologist for angiography and due to the lack of flow at the distal of the V3 segment, he decided to sacrifice this artery by two coils. Conclusion: Penetrating neck injuries are usually asymptomatic, but these injuries are often accompanied by hemorrhage, neurological symptoms, dysphagia, odynophagia, and windpipe. Penetrating lesions of the vertebral artery are rare and very difficult to diagnose. Also, these lesions are challenging for surgeons due to complex anatomy and difficult surgical exposure. So, endovascular treatment was used to treat the patient.
文摘Despite modern medicine’s advancements,age-related neurological diseases like Alzheimer’s disease and Parkinson’s disease remain challenging due to high costs,side effects,and limited accessibility.Ayurveda,a traditional Indian medicine system,offers Kadha tea as a potential herbal option.This review explores Kadha’s components(basil(Ocimum basilicum L.),black pepper(Piper nigrum L.),Cinnamon(Cinnamomum verum J.Presl),ginger(Zingiber officinale Roscoe),and raisin(Vitis vinifera L.))and their interaction with various neurological disorders.Studies suggest Kadha exhibits anti-inflammatory,antioxidant,and antiviral properties,potentially impacting Alzheimer’s disease,Parkinson’s disease,neurotoxicity,neuroinflammation,and brain trauma.By focusing on specific disease mechanisms and Kadha’s intergrade effects,this review aims to elucidate its potential role in managing age-related neurological disorders.
文摘miRNA-183 family, in normal biology, is expressed in a harmonious and stable manner in the neurosensory organs and cells. Studies have also shown that miRNA-183 family, in different pathways, affects the neurosensory development, maintenance, survival and function. In addition, it has potential neuroprotective effects in response to neurosensory destructive stimulations. miRNA-96 mutation causes hereditary deafness in humans and mice, and therefore affects the inner ear activity and its maintenance. Certain roles have been identified for mi R-96 in the maintenance and function of the inner ear. The comparison of the target genes of family-183 in transcriptomes of newborn and adult hair cells shows that hundreds of target genes in this family may affect development and maintenance of the ears. Identifying the genes that are regulated by miRNA-183 family provides researchers with important information about the complex development and environmental regulation of the inner ear, and can offer new approaches to the maintenance and regeneration of hair cells and auditory nerve.

文摘AIM: To determine the prevalence and causes of persistently elevated alanine aminotransferase (ALT) levels among the general population in northern Iran. METHODS: A total of 2292 (1376 female, aged 18-75 year), were selected by systematic clustered random sampling from the cities and villages of Gonbad and Kalaleh in Golestan Province and invited to participate in the study. A comprehensive history regarding alcohol drinking and medication was taken. Body mass index (BMI), viral markers and ALT levels were measured. If ALT level was ≥ 40 U/L, it was rechecked twice within 6 mo. Those with ≥ 2 times elevation of ALT were considered as having persistently elevated ALT level. Non-alcoholic fatty liver disease (NAFLD) was diagnosed based on evidence of fatty liver upon sonography and excluding other etiology. RESULTS: A total of 2049 (1351 female) patients participated in the study, 162 (7.9%) had elevated ALT level at the first measurement. Persistently elevated ALT level was detected in 64 (3.1%) participants, with51 (79.6%) with no obvious etiology, six (9.3%) with Hepatitis B, four (6.2%) with Hepatitis C virus (HCV) infection and three (4.6%) with alcoholic hepatitis. The prevalence of NAFLD and alcoholic hepatitis was 2.04% (42 patients) and 0.1% (three), respectively. There was correlation between NAFLD and male gender, overweight, diabetes and living in an urban area [odds ratio = 3.03 (95% CI: 1.6-5.72), 4.21 (95% CI: 1.83-9.68), 2.86 (95% CI: 1.05-7.79) and 2.04 (95% CI: 1.00-4.16) respectively]. CONCLUSION: NAFLD is the most common cause of persistently elevated serum ALT level among the general population of Iran.
文摘Hepatocellular carcinoma(HCC) is the fifth most common cancer, and hepatitis C virus(HCV) infection plays a major role in HCC development. The molecular mechanisms by which HCV infection leads to HCC are varied. HCV core protein is an important risk factor in HCV-associated liver pathogenesis and can modulate several signaling pathways involved in cell cycle regulation, cell growth promotion, cell proliferation, apoptosis, oxidative stress and lipid metabolism. The dysregulation of signaling pathways such as transforming growth factor β(TGF-β), vascular endothelial growth factor(VEGF), Wnt/β-catenin(WNT), cyclooxygenase-2(COX-2) and peroxisome proliferator-activated receptor α(PPARα) by HCV core protein is implicated in the development of HCC. Therefore, it has been suggested that this protein be considered a favorable target for further studies in the development of HCC. In addition, considering the axial role of these signaling pathways in HCC, they are considered druggable targets for cancer therapy. Therefore, using strategies to limit the dysregulation effects of core protein on these signaling pathways seems necessary to prevent HCV-related HCC.

文摘The potential impact of human leukocyte antigen （HLA） genotype variations on development of diabetic peripheral neuropathy （DPN） is not well determined. This study aimed to identify the association of HLA class II alleles with DPN in type 2 diabetes （T2D） patients. Totally 106 T2D patients, 49 with DPN and 57 without DPN, and 100 ethnic-matched healthy controls were analyzed. Both groups of the patients were matched based on sex, age, body mass index （BMI） and duration of T2D. Polyneuropathy was diagnosed using electrodiagnostic methods. HLA-DRB1 and DQB1 genotyping was performed in all subjects by the polymerase chain reaction with sequence-specific primers （PCR-SSP） method. T2D patients with DPN showed higher frequencies of HLA-DRB1＊10 and DRB1＊12 alleles compared to control group （P = 0.04）. HLA-DQB1＊02 allele and HLA-DRB1＊07-DQB1＊02 haplotype were associated with a decreased risk for developing DPN in T2D patients （P = 0.02 and P = 0.05 respectively）. Also, patients with severe neuropathy showed higher frequencies of DRB1＊07 （P = 0.003） and DQB1＊02 （P = 0.02） alleles than those with mild-to-moderate form of neuropathy. The distribution of DRB 1 and DQB 1 alleles and haplotypes were not statistically different between all patients and healthy controls. Our findings implicate a possible protective role of HLA-DQB1＊02 allele and HLA-DRB1＊07-DQB1＊02 haplotype against development of peripheral neuropathy in T2D patients. Therefore, variations in HLA genotypes might be used as genetic markers for prediction and potentially management of neuropathy in T2D patients.

文摘Inflammation plays an important role in the development of several cancers.Inflammatory cytokines,including tumor necrosis factor-α(TNF-α),are associated with the induction of inflammation.Chronic inflammation contributes to the progression of cancer through several mechanisms,including increased cytokine production and activation of transcription factors,such as nuclear factor-κB(NF-κB).Zerumbone(ZER),a component of subtropical ginger(Zingiber zerumbet Smith),seems to have anti-inflammatory,anti-cancer,and antioxidant activities.In this study,we aimed to explore the protective function and mechanisms of ZER against TNF-α-induced cancer-promoting cytokines.We found that the viability of stimulated human fibroblast cell lines was reduced after treatment with ZER(IC50=18µmol/L),compared to un-stimulated fibroblasts(IC50=40µmol/L).Besides,ZER inhibited mRNA expression and protein secretion of transforming growth factor-β(TGF-β),interleukin-33(IL-33),monocyte chemoattractant protein-1(MCP-1),and stromal cell-derived factor 1(SDF-1),which were produced by TNF-α-induced fibroblasts,as measured by quantitative real time-PCR(qRT-PCR)and ELISA assays.The mRNA expression levels of TGF-β,IL-33,SDF-1,and MCP-1 showed 8,5,2.5,and 4-fold reductions,respectively.Moreover,secretion of TGF-β,IL-33,SDF-1,and MCP-1 was reduced to 3.65±0.34 ng/mL,6.3±0.26,1703.6±295.2,and 5.02±0.18 pg/mL,respectively,compared to the untreated group.In addition,the conditioned media(CM)of TNF-α-stimulated fibroblasts increased the NF-κB expression in colorectal cancer cell lines(HCT-116 and Sw48),while in the vicinity of ZER,the expression of NF-κB was reversed.Considering the significant effects of ZER,this component can be used as an appropriate alternative herbal treatment for cancer-related chronic inflammation.
