RESUMO

Globally, breast cancer (BC) is the leading cause of cancer-related deaths in women. Hence, developing a therapeutic plan to overcome the disease is crucial. Numerous factors such as endogenous hormones and environmental factors may play a role in the pathophysiology of BC. Regarding the multi-modality treatment of BC, natural compounds like ellagic acid (EA) received has received increased interest in antitumor efficacy with lower adverse effects. Based on the results of this comprehensive review, EA has multiple effects on BC cells including (1) suppresses the growth of BC cells by arresting the cell cycle in the G0/G1 phase, (2) suppresses migration, invasion, and metastatic, (3) stimulates apoptosis in MCF-7 cells via TGF-ß/Smad3 signaling axis, (4) inhibits CDK6 that is important in cell cycle regulation, (5) binds to ACTN4 and induces its degradation via the ubiquitin-proteasome pathway, inducing decreased cell motility and invasion in BC cells, (6) inhibits the PI3K/AKT pathway, and (7) inhibits angiogenesis-associated activities including proliferation (reduces VEGFR-2 tyrosine kinase activity). In conclusion, EA exhibits anticancer activity through various molecular mechanisms that influence key cellular processes like apoptosis, cell cycle, angiogenesis, and metastasis in BC. However, further researches are essential to fully elucidate its molecular targets and implications for clinical applications.

RESUMO

Background: Cisplatin has potent antitumor properties. It has several toxic side effects, such as hepatotoxicity. It is thought that hepatotoxicity induced by cisplatin is caused by oxidative stress. Objectives: It has shown that calcium dobesilate (CD) has potent antioxidant properties. The present study aimed to assess CD protective effects on cisplatin-induced hepatotoxicity in mice. Methods: In this study, 28 mice were selected randomly and were divided into four groups, including control, cisplatin (20 mg/kg, i.p., only on the first day of the experiment), Cisplatin+CD 50 (50 mg/kg CD, orally), and Cisplatin+CD 100 (cisplatin with 100 mg/kg CD, orally). A 4-day oral gavage of CD was applied to the treated groups. The mice were sacrificed on the 5th day, and serum glutamic pyruvic transaminase (SGPT), serum glutamic-oxaloacetic transaminase (SGOT), alkaline phosphatase (ALP), malondialdehyde (MDA) and reactive oxygen species (ROS) levels, superoxide dismutase (SOD), and glutathione peroxidase (GPx) enzyme activity levels in liver tissue were evaluated. Histopathological evaluation was assessed using hematoxylin and eosin-stained liver tissue sections. Results: The results indicated that there was a significant increase in GSPT, SGOT, ALP, and MDA and also a significant reduction in the liver activity of SOD and GPx in cisplatin-treated animals. Treatment with CD (100 mg/kg) remarkably attenuated the GSPT, SGOT, ALP, MDA, and ROS levels. Moreover, CD (100 mg/kg) elevated the SOD and GPx activity in the liver tissue of cisplatin-treated mice. Conclusions: The findings showed that CD has a protective effect against cisplatin-induced hepatotoxicity, at least by improving the antioxidant parameters.

RESUMO

The aim of this study was to introduce a patient with mucinous nonneoplastic cyst (MNNC) at an unusual age. MNNCs of the pancreas are uncommon primary tumors, which affect middle-aged women in their fifth decade of life and have significant malignant potential. Therefore, it is important to accurately diagnose and remove them. This case is a 28-year-old woman patient who presented with a pain in the right and upper abdomen from 3 months ago and worsened at night. A cystic lesion was observed near the upper bridge of the left kidney in abdominal ultrasonography. Contrast-enhanced abdominal computed tomography (CT) scan showed a cystic lesion in the trunk and umbilical cord of the pancreas. The patient underwent surgery and the mass was removed and the MNNC was diagnosed.

RESUMO

Colon cancer (CC) is one of the most common and deadly cancers worldwide. Oncologists are facing challenges such as development of drug resistance and lack of suitable drug options for CC treatment. Flavonoids are a group of natural compounds found in fruits, vegetables, and other plant-based foods. According to research, they have a potential role in the prevention and treatment of cancer. Apigenin is a flavonoid that is present in many fruits and vegetables. It has been used as a natural antioxidant for a long time and has been considered due to its anticancer effects and low toxicity. The results of this review study show that apigenin has potential anticancer effects on CC cells through various mechanisms. In this comprehensive review, we present the cellular targets and signaling pathways of apigenin indicated to date in in vivo and in vitro CC models. Among the most important modulated pathways, Wnt/ß-catenin, PI3K/AKT/mTOR, MAPK/ERK, JNK, STAT3, Bcl-xL and Mcl-1, PKM2, and NF-kB have been described. Furthermore, apigenin suppresses the cell cycle in G2/M phase in CC cells. In CC cells, apigenin-induced apoptosis is increased by inhibiting the formation of autophagy. According to the results of this study, apigenin appears to have the potential to be a promising agent for CC therapy, but more research is required in the field of pharmacology and pharmacokinetics to establish the apigenin effects and its dosage for clinical studies.

RESUMO

Growing prevalence of obesity among youth would have adverse consequences and increased risk of developing chronic diseases at older ages. This study explored the prevalence of obesity and its association with relevant risk factors in the Rafsanjan youth cohort population. This cross-sectional study was done on 3006 individuals from the 15-35-year-old population included in the Rafsanjan youth cohort study. The data were extracted from the youth cohort databases, which had been collected through in-person interview and standard questionnaires. Definition of general obesity was considered as body mass index ≤ 30 and that of central obesity as waist to hip ratio (WHR) ≥ 0.9 for men and ≥ 0.85 for women. Multivariate stepwise proportional odds model and multivariable stepwise logistic regression models were done to explore the factors associated with general obesity and central obesity. The mean age was 25.78 ± 6.06 years with 56% (n = 1683) female. The prevalence of general obesity was 15.80% (95% CI 14.50-17.11) and central obesity was 28.41% (95% CI 26.80-30.02). The risk of general obesity increased with increasing age (OR = 1.053, P < 0.0001), being married (OR = 1.658, P < 0.0001), history of diabetes (OR = 1.609, P = 0.0185), history of hypertension (OR = 1.609, P < 0.0001), elevated triglyceride (OR = 1.007, P < 0.0001) and LDL (OR = 1.015, P < 0.0001), while decreasing with being employed (OR = 0.748, P = 0.0002) and elevated HDL (OR = 0.975, P < 0.0001). Prevalence of obesity was high in study population. Marital status, increasing age, and history of chronic diseases were associated with obesity. Preventing programs should be developed against obesity and for promoting healthy habits in young adult especially during education at schools.

RESUMO

Signal transducers and activators of transcription 3 (STAT 3) have been proposed to be responsible for breast cancer development. Moreover, evidence depicted that upregulation of STAT3 is responsible for angiogenesis, metastasis, and chemo-resistance of breast cancer. Tamoxifen (TAM) resistance is a major concern in breast cancer management which is mediated by numerous signaling pathways such as STAT3. Therefore, STAT3 targeting inhibitors would be beneficial in breast cancer treatment. The information on the topic in this review was gathered from scientific databases such as PubMed, Scopus, Google Scholar, and ScienceDirect. The present review highlights STAT3 signaling axis discoveries and TAM targeting STAT3 in breast cancer. Based on the results of this study, we found that following prolonged TAM treatment, STAT3 showed overexpression and resulted in drug resistance. Moreover, it was concluded that STAT3 plays an important role in breast cancer stem cells, which correlated with TAM resistance.

RESUMO

Parkinson's disease (PD) as a prevalent neurodegenerative condition impairs motor function and is caused by the progressive deterioration of nigrostriatal dopaminergic (DAergic) neurons. The current therapy solutions for PD are ineffective because they could not inhibit the disease's progression and they even have adverse effects. Natural polyphenols, a group of phytochemicals, have been found to offer various health benefits, including neuroprotection against PD. Among these, resveratrol (RES) has neuroprotective properties owing to its capacity to protect mitochondria and act as an antioxidant. An increase in the formation of reactive oxygen species (ROS) leads to oxidative stress (OS), which is responsible for cellular damage resulting in lipid peroxidation, oxidative protein alteration, and DNA damage. In PD models, it's been discovered that RES pretreatment can diminish oxidative stress by boosting endogenous antioxidant status and directly scavenging ROS. Several studies have examined the involvement of RES in the modulation of the transcriptional factor Nrf2 in PD models because this protein recognizes oxidants and controls the antioxidant defense. In this review, we have examined the molecular mechanisms underlying the RES activity and reviewed its effects in both in vitro and in vivo models of PD. The gathered evidence herein showed that RES treatment provides neuroprotection against PD by reducing OS and upregulation of Nrf2. Moreover, in the present study, scientific proof of the neuroprotective properties of RES against PD and the mechanism supporting clinical development consideration has been described.

RESUMO

Introduction: Identification of factors associated with blood pressure (BP), including hemoglobin, can be used in diagnosing, controlling, and predicting the prognosis of patients. This study aims to investigate the cross-sectional association between hemoglobin concentration and BP in people aged 35-70 years in a cohort study of Rafsanjan, Iran. Method: This cross-sectional study was conducted on 9398 urban and rural population of Rafsanjan adult cohort study as a part of the prospective epidemiological research studies in Iran (PERSIAN). Demographic information, medical history, history of smoking and alcohol intake, systolic and diastolic BP, and hemoglobin concentration were collected. A logistic regression test was performed to evaluate the relationship between hemoglobin concentration and BP in 4 unadjusted and adjusted models based on demographic indicators, clinical and laboratory findings using SPSS.24 software and SAS software version 9.2. Results: The mean age of the participants was 49.78 ± 9.53 years, and 53.2% (5002 people) were women. Adjusted models 3 and 4 showed a positive association between BP and hemoglobin. For each unit increase in hemoglobin, the odds ratio (OR) of BP in the adjusted model 3 was 1.062 (95% CI: 1.005-1.121), and in the adjusted model 4, it was 1.090 (95% CI: 1.031-1.153). Conclusion: Based on the results, the positive trend of BP and hemoglobin levels may indicate the need to pay more attention to these people as higher-risk groups for hypertension.

RESUMO

Cardiovascular disease (CVD) is the leading cause of death and disability in people with diabetes mellitus (DM), since finding the correlation between DM and CVD risk factors can be effective in preventing the incidence of morbidity and mortality in patients. This study aimed to determine the prevalence of cardiovascular risk factors in people with and without metabolic syndrome (MtS) in DM. This cross-sectional study was part of the Rafsanjan Cohort Study as part of the comprehensive Persian (Prospective Epidemiological Research Studies in IRAN) on 35-70-year old adults with and without MtS in DM. Indicators of CVD risk factors, including gender, age, blood pressure, dyslipidemia, smoking, alcohol consumption, fasting blood sugar, creatinine, blood urea, waist circumference, body mass index, family history, physical inactivity, and fruit and vegetable consumption, were collected in the Persian Cohort Questionnaire. The data was analyzed by SPSS software version 22. The prevalence of MtS in 1933 participants was estimated to be 80% (95% confidence interval 78.1-81.8%). In the logistic regression model, smoking, alcohol consumption, and triglycerides were identified as the factors associated with MtS. Our results show that, based on our study, the prevalence of cardiovascular risk factors in DM was high. The suggested solutions in this field are to reduce smoking and alcohol consumption, as well as to control hypertension, hyperlipidemia, and being overweight.

RESUMO

In the present study, the health-protective and therapeutic properties of MET have been discussed, focusing on the effect of MET on the Nrf2 expression in patients with different pathological conditions. Metformin (MET) regulates high blood glucose, thus being an integral part of the antidiabetic medications used to treat type 2 diabetes mellitus. It belongs to biguanide class medications that are administered through the oral route. Moreover, the agent is widely known for its anti-cancer, anti-oxidant, anti-inflammatory, and neuroprotective effects. The MET modulates the nuclear factor erythroid-2 related factor-2 (Nrf2) signaling pathway, which in turn yields the above-mentioned medical benefits to patients. The Nrf2 signaling pathways are modulated in multiple ways described subsequently: 1) MET acts on the cancer cells and inactivates Raf-ERK signaling, thus reducing Nrf2 expression, 2) MET obstructs the expression of proteins that are involved in apoptosis of tumor cells and also prevents tumor cells from oxidation through an AMPK-independent pathway; 3) MET carries out Keap1-independent mechanism for reducing the levels of Nrf2 protein in cancer cells; 4) MET upregulates the Nrf2-mediated transcription to stimulate the anti-oxidant process that prevents oxidative stress in cells system and consequently gives neuroprotection from rotenone and 5) MET downregulates p65 and upregulates Nrf2 which helps improve the angiogenesis impairment stimulated by gestational diabetes mellitus. This article presents an analysis of the health-protective properties of MET and also sheds light on the effect of MET on the Nrf2 expression in patients with different pathological conditions.

RESUMO

BACKGROUND: Postpartum depression has a negative impact on both infants and women. This study aimed to determine the correlates of postpartum depression in women in southern Iran. METHODS: This cross-sectional study was performed on 186 mothers who had recently given birth to a baby. Data were collected using the demographic form, Quality of Prenatal Care Questionnaire, Edinburgh Postnatal Depression Scale (EPDS), Depression, Anxiety and Stress Scale-21 items (DASS-21) 3 days after delivery and EPDS and DASS-21 6 months after childbirth. RESULTS: Postpartum depression (PPD) was 24.2% and 3.2% 3 days and 6 months after delivery, respectively. Anxiety, Prenatal Care Quality and educational level predicted 34.0% of the variance of PPD 3 days after delivery (R2 = 34.0%). Anxiety, type of delivery, and stress predicted 24% of the variance of PPD 6 months after delivery (R2 = 24.0%). CONCLUSIONS: With an increase in stress and anxiety and a reduction in the quality of prenatal care, the risk of postpartum depression increases. Therefore, attention to the quality of prenatal care and postpartum stress and anxiety should be carefully evaluated to prevent PPD. Psychological support and interventions are recommended to promote the mental health of women before and after childbirth.

RESUMO

Traumatic brain injury (TBI) is still a major cause of concern for public health, and out of all the trauma-related injuries, it makes the highest contribution to death and disability worldwide. Patients of TBI continue to suffer from brain injury through an intricate flow of primary and secondary injury events. However, when treatment is provided in a timely manner, there is a significant window of opportunity to avoid a few of the serious effects. Pioglitazone (PG), which has a neuroprotective impact and can decrease inflammation after TBI, activates peroxisome proliferator-activated receptor-gamma (PPARγ). The objective of the study is to examine the existing literature to assess the neuroprotective and anti-inflammatory impact of PG in TBI. It also discusses the part played by microglia and cytokines in TBI. According to the findings of this study, PG has the ability to enhance neurobehavior, decrease brain edema and neuronal injury following TBI. To achieve the protective impact of PG the following was required: (1) stimulating PPARγ; (2) decreasing oxidative stress; (3) decreasing nuclear factor kappa B (NF-κB), interleukin 6 (IL-6), interleukin-1ß (IL-1ß), cyclooxygenase-2 (COX-2), and C-C motif chemokine ligand 20 (CCL20) expression; (4) limiting the increase in the number of activated microglia; and (5) reducing mitochondrial dysfunction. The findings indicate that when PIG is used clinically, it may serve as a neuroprotective anti-inflammatory approach in TBI.

RESUMO

Cytokine storm is a main complication in the hospitalized patients, who are infected with the novel coronavirus (COVID-19). The pro-inflammatory cytokines are the main causes of the cytokine storm, however, the roles played by IL-17A, IL-23 and CCL3 are yet to be clarified completely. This prospective study was aimed to explore serum levels of these cytokines in the hospitalized patients infected by COVID-19. Serum levels of IL-17A, IL-23 and CCL3 were measured in 30 COVID-19 infected patients in parallel with 30 healthy controls using ELISA technique. Although serum levels of IL-17A, IL-23 and CCL3 did not alter in the patients in comparison to healthy controls, male patients had higher serum levels of IL-23 than women. Hypertension, type 2 diabetes, lung involvement and age did not affect serum levels of IL-17A, IL-23 and CCL3 in the patients. It appears that IL-17A, IL-23 and CCL3 do not participate in the pro-inflammatory responses in Iranian hospitalized COVID-19 infected patients. However, the gender can be considered as a risk factor for production of more IL-23, which needs to be explored further.

RESUMO

BACKGROUND: Reverse transcription-polymerase chain reaction (RT-PCR) is a standard technique for diagnosing coronavirus disease 2019 (COVID-19). The parameters for the diagnosis of COVID-19 included the history of exposure to positive COVID-19 patients, clinical signs and symptoms related to the disease, inflammation factors in the blood test or positive antigen-antibody test, and chest computed tomography (CT) findings. The current study evaluated the chest CT scan findings in patients with respiratory problems following positive RT-PCR of COVID 19. MATERIALS AND METHODS: This cross-sectional study was performed on 120 patients referred to Ali Ibn-Abi Talib Hospital in Rafsanjan, Kerman Province, Iran, with respiratory symptoms between Dec-2019 to Dec-2020. Two radiologists reviewed the chest CT scans of these patients using the checklist that included parameters such as the types of involvement (consolidation/grand-glass/crazy paving, etc.) and the patterns of involvement (central/peripheral), and the pleural findings. RESULTS: The CT scan was conducted in 107 patients with a typical condition and 11 patients with an atypical form of the disease. The frequency of the typical CT image of COVID-19 in the male group was significantly higher than that in the female group (P=0.004). The frequency of reverse halo sign, septal thickening, cardiomegaly, and crazy paving was significantly higher in males than in females (P≤0.05). Also, there was a significant difference between age groups based on the number of involved lobes (P=0.04). CONCLUSION: Chest CT scan is an important diagnostic method for COVID 19 with high sensitivity. The parameters in the CT scan are beneficial for the diagnosis of COVID 19. In addition, some characters in CT scans in the male gender are more specific.

RESUMO

BACKGROUND AND OBJECTIVE: Neurological diseases are becoming a significant problem worldwide, with the elderly at a higher risk of being affected. Several researchers have investigated the neuroprotective effects of Carvacrol (CAR) (5-isopropyl-2-methyl phenol). This review systematically surveys the existing literature on the impact of CAR when used as a neuroprotective agent in neurological diseases. METHODS: The systematic review involved English articles published in the last ten years obtained from PubMed, Google Scholar, and Scopus databases. The following descriptors were used to search the literature: "Carvacrol" [Title] AND "neuroprotective (neuroprotection)" [Title] OR "stroke, traumatic brain injury, Alzheimer's disease, Parkinson's disease, seizure, epilepsy [Title]. RESULTS: A total of 208 articles were retrieved during the search process, but only 20 studies met the eligibility criteria and were included for review. A total of 20 articles were identified, in which the efficacy of CAR was described in experimental models of stroke, traumatic brain injury, Parkinson's disease, Alzheimer's disease, epilepsy, and seizure, through motor deficits improvements in neurochemical activity, especially antioxidant systems, reducing inflammation, oxidative stress and apoptosis as well as inhibition of TRPC1 and TRPM7. CONCLUSION: The data presented in this study support the beneficial impact of CAR on behavioural and neurochemical deficits. CAR benefits accrue because of its anti-apoptotic, antioxidant, and anti- inflammatory properties. Therefore, CAR has emerged as an alternative treatment for neurological disorders based on its properties.

RESUMO

A better perception of the factors associated with patient activation, as a way to improve self-management, is the most important step in planning patient-centered education for chronic disease management. Therefore, the present study is aimed at investigating the relationship between activation, stress, anxiety, depression, and quality of life (QOL) in patients with chronic diseases. This correlational study was performed on 293 chronic patients admitted to coronary care units (CCUs) in one of the hospitals in Rafsanjan. The Patient Activation Measure (PAM), Quality of Life-BREF (WHOQOL-BREF), and Depression, Anxiety, and Stress Scale-21 Items (DASS-21) were used to collect data. The data were then analyzed using SPSS 22. A significant positive correlation was observed between general QOL and PAM (P < 0.001). In addition, a significant negative correlation was found between PAM, stress (P = 0.032), and depression (P = 0.025). The results of multivariate linear regression indicated that only physical and psychological subscales of QOL significantly predicted PAM (B = 0.24; 95% confidence interval; P value < 0.05). Owing to the fact that some subscales of QOL have a determinant role in the PAM of chronic patients, healthcare providers are recommended to plan and implement the necessary interventions to improve the QOL and the health outcomes of chronic patients.

RESUMO

The infant's refusal to breastfeed can be a stressful and concerning matter for a mother. This study aimed to investigate the frequency and factors leading to nursing strikes in Rafsanjan city. This descriptive study was performed on infants who had been referred to the pediatrician's office with a complaint of a nursing strike. The research sample included 70 infants, and all the required data, including the causes of the nursing strike and the demographic information of the mother and the infant, were collected using a checklist. The Statistical Package for the Social Sciences (SPSS) software version 20 was used to analyze the data. The percentage was used to express qualitative indices, and the mean and standard deviation were used to express quantitative indices. The results showed that the most common factors contributing to the infants' breast refusal were playfulness and distraction (50%) and recent vaccinations in the last 12 days (48.6%). Besides, the most common maternal factors affecting breast refusal were level of education (67.1%), recent acute stress (41.4%), and inadequate milk production (35.7%). The results of the present study showed that playfulness and distraction of the baby, recent vaccination, use of a pacifier, level of education and recent stress of the mother, breastfeeding program, and insufficient milk production are the most common reasons for nursing strikes.

RESUMO

Cisplatin is one of the synthetic cancer medicines with nephrotoxicity being one of its major side effects. Past research shows that calcium dobesilate (CaD), as a vascular protective agent in diabetic retinopathy, has antioxidant properties. Thus, this study aims to evaluate the protective effects of CaD in cisplatin-induced nephrotoxicity in mice. A many as 28 mice, in the present experimental research, were randomly distributed into four groups, including control, cisplatin (the intraperitoneal administration of 20 mg/kg cisplatin only on the first day of the experiment), cisplatin + CaD 50 (cisplatin with the oral administration of 50 mg/kg CaD), and cisplatin + CaD 100 (cisplatin with the oral administration of 100 mg/kg CaD). The treated groups received CaD by oral gavage for 4 constitutive days. On the fifth day, the mice were sacrificed, and some biochemical (serum levels of Cr and BUN, renal tissue levels of MDA, and renal activities of SOD and GPx) and pathological parameters were evaluated. Based on the results, there was a significant decrease in the renal SOD and GPx activities; in contrast, there was a significant increase in the BUN, Cr, and renal MDA levels following administering cisplatin. However, the CaD treatment (100 mg/kg) significantly attenuated these alterations. In addition, the kidney's histological examination of kidneys confirmed the nephroprotective effects of CaD. The findings proved the protective impact of CaD on cisplatin-induced nephrotoxicity by an improvement in the oxidative stress factors.

RESUMO

Troxerutin (TRX), a semi-synthetic bioflavonoid derived from rutin, has been reported to exert several pharmacological effects including antioxidant, anti-inflammatory, antihyperlipidemic, and nephroprotective. However, the related molecular details and its mechanisms remain poorly understood. In the present review, we presented evidences from the diversity in vitro and in vivo studies on the therapeutic potential of TRX against neurodegenerative, diabetes, cancer and cardiovascular diseases with the purpose to find molecular pathways related to the treatment efficacy. TRX has a beneficial role in many diseases through multiple mechanisms including, increasing antioxidant enzymes and reducing oxidative damage, decreasing in proapoptotic proteins (APAF-1, BAX, caspases-9 and-3) and increasing the antiapoptotic BCL-2, increasing the nuclear translocation of nuclear factor erythroid 2-related factor 2 (Nrf2) and downregulating the nuclear factor κB (NFκ). TRX also reduces acetylcholinesterase activity and upregulates phosphoinositide 3- kinase/Akt signaling pathway in Alzheimer's disease models. Natural products such as TRX may develop numerous and intracellular pathways at several steps in the treatment of many diseases. Molecular mechanisms of action are revealing novel, possible combinational beneficial approaches to treat multiple pathological conditions.
