Overview of the role and action mechanism of microRNA-128 in viral infections.

Recently in vivo and in vitro studies have provided evidence establishing the significance of microRNAs (miRNAs) in both physiological and pathological conditions. In this regard, the role of miRNA-128 (miR-128) in health and diseases has been found, and its critical regulatory role in the context of some viral diseases has been recently identified. For instance, it has been found that miR-128 can serve as an antiviral mediator and significantly limit the replication and dissemination of human immunodeficiency virus type 1 (HIV-1). Besides, it has been noted that poliovirus receptor-related 4 (PVRL4) is post-transcriptionally regulated by miR-128, representing possible miRNA targets that can modulate measles virus infection. Of note, the downregulation of seminal exosomes eca-miR-128 is associated with the long-term persistence of Equine arteritis virus (EAV) in the reproductive tract, and this particular miRNA is a putative regulator of chemokine ligand 16 (C-X-C motif) as determined by target prediction analysis. In this review, the latest information on the role and action mechanism of miR-128 in viral infections will be summarized and discussed in detail.

Associations between empirically derived dietary patterns and oxidative stress and inflammation in adults with primary hypothyroidism: a case-control study.

BACKGROUND: Primary hypothyroidism is a common endocrine disorder caused by impaired production of thyroid hormones. Recent studies have shown that dietary habits, oxidative stress, and inflammation may play roles in thyroid hypofunction. Thus, the present article aimed to determine the relationship between major dietary patterns and oxidative stress and inflammation in primary hypothyroid patients and healthy people in Iranian adults. METHODS: This matched case-control study was conducted on 200 participants (100 cases and 100 controls). The presence of primary hypothyroidism was determined by endocrinologists based on American Thyroid Association (ATA) criteria. Dietary intake was assessed using a validated 168-item, semi-quantitative food frequency questionnaire (FFQ). The principal component analysis (PCA) method was used to derive major dietary patterns. Statistical analysis was performed using logistic regression analysis, and the findings were reported using odds ratios (ORs) with 95% CIs. RESULTS: We identified 2 major dietary patterns (i.e., healthy and Western dietary patterns). After adjusting for confounding variables, participants in the highest tertile of the healthy eating pattern had lower odds of primary hypothyroidism. Also, there was a significant relationship between total antioxidant capacity (TAC) levels and thyroid hypofunction; however, no significant correlation was seen between the Western dietary pattern and malondialdehyde (MDA) and C-reactive protein (CRP) with hypothyroidism. CONCLUSIONS: There were statistically direct associations between healthy dietary patterns (loaded with vegetables, nuts and seeds, fruits, dried fruits, olives, garlic, black pepper, starchy vegetables, low-fat dairy, and legumes) and increased TAC levels with a decreased risk of thyroid hypofunction. However, Western dietary patterns and MDA and CRP levels did not associate with an underactive thyroid.

Dietary caffeine intake is associated with favorable metabolic profile among apparently healthy overweight and obese individuals.

BACKGROUND: Recent studies have revealed some conflicting results about the health effects of caffeine. These studies are inconsistent in terms of design and population and source of consumed caffeine. In the current study, we aimed to evaluate the possible health effects of dietary caffeine intake among overweight and obese individuals. METHODS: In this cross-sectional study, 488 apparently healthy individuals with overweight and obesity were participated. Dietary intake was assessed by a Food Frequency Questionnaire (FFQ) and the amount of dietary caffeine was calculated. Body composition was determined by bioelectrical impedance analysis (BIA). Enzymatic methods were used to evaluate serum lipid, glucose, and insulin concentrations. RESULTS: Those at the highest tertile of dietary caffeine intake had lower percentage of fat mass, higher fat free mass and appetite score (P < 0.05). Also, lower total cholesterol (TC) and low density lipoprotein cholesterol (LDL-c) was observed in higher tertiles of dietary caffeine intake compared with lower tertiles. In multinomial adjusted models, those at the second tertile of dietary caffeine intake were more likely to have higher serum insulin (P = 0.04) and lower homeostatic model assessment of insulin resistance (HOMA-IR) values compared with first tertile (P = 0.03) in crude model. While, in the age, body mass index (BMI), sex, physical activity, socio-economic status (SES) and energy intake -adjusted model (Model III), those at the third tertile of dietary caffeine intake were more likely to have low serum LDL concentrations [odds ratio (OR) = 0.957; CI = 0.918-0.997; P = 0.04]. With further adjustment to dietary vegetable, fiber and grain intake, those at the third tertile of dietary caffeine intake were more likely to have low systolic blood pressure (SBP), LDL and high HDL levels compared with those at the first tertile (P < 0.05). CONCLUSION: High intakes of dietary caffeine was associated with lower LDL, SBP, insulin resistance and higher HDL concentrations among overweight and obese individuals. However, due to observational design of the study, causal inference is impossible and further studies are warranted to confirm our findings.

Dietary polyphenol intake, body composition and components of metabolic syndrome in a sample overweight and obese adults: a cross-sectional study.

BACKGROUND: The health benefits of dietary polyphenol intake (DPI) including improved lipid profiles, blood pressure, insulin resistance, and reduced systemic inflammation has revealed previously. However, the results of numerous studies are not consistent and it seems that these health effects are attributed to some of DPI. In the current research, we evaluated the health benefits of DPI on metabolic markers and glycemic markers among overweight and obese individuals. METHODS: In this cross-sectional study, 487 individuals with overweight and obesity were participated. Dietary intake was assessed by a Food Frequency Questionnaire (FFQ) and the amount of dietary polyphenol intake were calculated based on the information derived from Phenol-Explorer database ( www.phenolexplorer.eu/contents ). Bioelectrical impedance analysis (BIA) was used to measure body composition. Systolic and diastolic blood pressures were measured by sphygmomanometer. Biochemical assays including fasting blood sugar, insulin and serum lipids' concentrations were measured by enzymatic methods. RESULTS: According to our results, males were more likely to be at the highest tertile of DPI (P = 0.04). Also, those at the highest tertile of DPI had higher fat free mass and physical activity level (P < 0.05). Lower TG level in highest tertile of DPI in crude model was also observed, but, it lost its significant threshold after adjustment for confounders. Subjects at the second tertile of DPI were more likely to have lower systolic blood pressure in the sex and age adjusted model [OR = 0.970; CI = 0.940-1.000; P = 0.049]. For other biochemical variables, no significant association was observed. CONCLUSION: In the current study, total dietary polyphenol intake was associated with lower SBP among overweight and obese individuals. Further studies are warranted to better elucidate the observed results.

Soluble receptor for advanced glycation end products (sRAGE) is associated with obesity rates: a systematic review and meta-analysis of cross-sectional study.

BACKGROUND: Several studies have highlighted the possible positive effects of soluble receptor for advanced glycation end products (sRAGE) against obesity. However, due to their inconsistent results, this systematic review and meta-analysis aimed to quantitatively evaluate and critically review the results of studies evaluating the relationship between sRAGE with obesity among adult population. METHODS: In the systematic search, the eligibility criteria were as follows: studies conducted with a cross-sectional design, included apparently healthy adults, adults with obesity, or obesity-related disorders, aged over 18 years, and evaluated the association between general or central obesity indices with sRAGE. RESULTS: Our systematic search in electronic databases, including PubMed, Scopus, and Embase up to 26 October, 2023 yielded a total of 21,612 articles. After removing duplicates, screening the titles and abstracts, and reading the full texts, 13 manuscripts were included in the final meta-analysis. According to our results, those at the highest category of circulating sRAGE concentration with median values of 934.92 pg/ml of sRAGE, had 1.9 kg/m2 lower body mass index (BMI) (WMD: -1.927; CI: -2.868, -0.986; P < 0.001) compared with those at the lowest category of sRAGE concentration with median values of 481.88 pg/ml. Also, being at the highest sRAGE category with the median values of 1302.3 pg/ml sRAGE, was accompanied with near 6 cm lower waist circumference (WC) (WMD: -5.602; CI: -8.820, -2.383; P < 0.001 with 86.4% heterogeneity of I2) compared with those at the lowest category of sRAGE concentration with median values of 500.525 pg/ml. Individuals with obesity had significantly lower circulating sRAGE concentrations (WMD: -135.105; CI: -256.491, -13.72; P = 0.029; with 79.5% heterogeneity of I2). According to the subgrouping and meta-regression results, country and baseline BMI were possible heterogeneity sources. According to Begg's and Egger's tests and funnel plots results, there was no publication bias. CONCLUSION: According to our results, higher circulating sRAGE concentrations was associated with lower BMI and WC among apparently healthy adults. Further randomized clinical trials are warranted for possible identification of causal associations.

The Prophylaxis Effect of Ephedrine on Hemodynamic Variation in Patients Undergoing Percutaneous Nephrolithotomy Surgery with Spinal Anesthesia.

Background: Performing spinal anesthesia with at least hemodynamic variation and complications is always challenging for anesthesiologists. In this study, we investigated the effect of ephedrine and placebo on hemodynamic changes in patients undergoing percutaneous nephrolithotomy with spinal anesthesia. Methods: This randomized, double-blind prospective clinical trial was conducted on 120 patients aged 20‒60 years with ASA (American Society of Anesthesiologists) classes I and II. Patients who were candidates for percutaneous nephrolithotomy with spinal anesthesia were divided into intervention (received 1 cc = 5 mg ephedrine) and control groups (received 1 cc normal saline). All vital parameters, including HR (heart rate) and NIBP (noninvasive blood pressure), were recorded perioperatively T0-T25) and finally at the end of surgery time (Tf). The results were analyzed by SPSS software version 23, and a P value ≤0.05 was considered significant. Results: The mean arterial pressure during surgery between T3 and T9 and the mean heart rate in times of T3-T8 in the intervention group were higher than in the control group, and this difference was statistically significant (P < 0.05). The incidence of hypotension, bradycardia, nausea, and vomiting and the amount of prescribed ephedrine, atropine, and ondansetron in the control group were higher than in the intervention group (P=0.001). Seven patients in the control group and four in the intervention group had shivering, but this difference was not statistically significant (P=0.43). Conclusion: This study showed the effectiveness of the prescription of 5 mg ephedrine two minutes before changing from the lithotomy position to the supine in maintaining hemodynamic stability, reducing hypotension, bradycardia, nausea, and vomiting, and the amount of prescribed ephedrine, atropine, and ondansetron.

Association between maternal exposure to arsenic by drinking water during pregnancy and risk of preterm birth: a systematic review and meta-analysis.

The relation of exposure to arsenic in drinking water during pregnancy to the risk of preterm birth (PTB) was contradictory. This meta-analysis aimed to examine the association between drinking water arsenic and PTB. A systematic search in PubMed and Scopus was performed to achieve all relevant studies. Odds ratios (OR) and 95% confidence intervals (CI) were used to pool data using the random-effect models. Overall, 11 studies with a total sample size of 3,404,189 participants were included in the meta-analysis. Arsenic exposure through drinking water during pregnancy was related to an increased risk of PTB (OR = 1.06; 95%CI = 1.01-1.10 for highest versus lowest category of arsenic), with significant heterogeneity across the studies (I2 = 84.8%, P = 0.001). This finding was supported by cohort studies (OR = 1.05; 95%CI = 1.01-1.10). This meta-analysis proposes that higher arsenic exposure in drinking water may be a risk factor for PTB.

Parental health-seeking behavior on self-medication, antibiotic use, and antimicrobial resistance in children.

Aim and Objectives: The study sought to identify parental trends in children's self-medication, health-seeking behavior, knowledge of self-medication, antibiotic use, and antimicrobial resistance in Asir, Saudi Arabia. Methods: A web-based cross-sectional study was carried out by a survey questionnaire. Snow Ball sampling technique was used to select the Eight hundred and sixteen parents with children in the Asir region by WhatsApp and email, and 650 participants who met the inclusion criteria consented to participate in the study. Results: There were 1809 episodes of childhood illnesses reported during the study period. The mean scores are on knowledge at 8.11 ±â€¯2.43, favorable attitude at 17.60 ±â€¯1.17, and practice was 7.72 ±â€¯1.72, and a significant correlation was found between knowledge, attitude, and practice (KAP) at p = 0.01. Out of 624, the majority of parents showed strong knowledge and proficiency in antibiotics. However, the attitude scores of over 50% towards the usage of antibiotics were subpar. Around 54% of parents were self-medicating their children and 43% were unaware that skipping doses contributes to anti-microbial resistance (AMR). The facilitators for self-medication were male gender (aOR: 2.13; 95% CI: 1.26-3.98, p < 0.05), having more children (aOR: 2.78; 95% CI: 1.27-4.12 p < 0.01), professional qualification (aOR:3.07; 95% CI 1.57- 4.68; p < 0.01), residing in urban area (aOR: 3.17; 95% CI: 2.13-5.61, p < 0.05), working in health care (aOR: 5.99; 95% CI: 1.78-18.2, p < 0.01) and high income (aOR: 3.57; 95% CI: 2.08-6.34, p < 0.05). Conclusions: The findings indicated that the majority of parents had unfavorable views and improper practices of antibiotic usage. Strategic education programs to the targeted population, especially to the parents about side effects of antibiotics, dangerous consequences of self-medication, and crucial AMR concerns must be addressed immediately.

A Systematic Review and Meta-Analysis on Death Anxiety During COVID-19 Pandemic.

This systematic review was conducted to estimate the pooled score of death anxiety during the COVID-19 pandemic. All eligible articles from January 2020 to May 2022 reporting the death anxiety score were included in the analysis b.y searching the Scopus, PubMed, Embase, and ISI databases. The standard score of death anxiety in the COVID-19 pandemic was 50%. The highest score of death anxiety was related to patients with COVID-19 (59.4%), other chronic patients (58.9%), and the elderly (56.4%). The lowest death anxiety score was related to the general population (42.9%) and health care workers (48.2%). The death anxiety score in the studies whose data was collected in 2020 and 2021 was 51% and 62%, respectively. During the COVID-19 pandemic, people experienced high death anxiety, which had terrible effects on their lives. Therefore, it seems necessary to provide training courses to deal with death anxiety for other possible pandemics.

Relatives' involvement in the care of patients in acute medical wards in two different countries-An ethnographic study.

AIMS AND OBJECTIVES: To explore the nature of relatives' involvement in the care of patients in acute medical settings in Australia and Saudi Arabia and to explore the perceptions, attitudes and experiences of nurses. BACKGROUND: There is little known about how relatives respond to being involved in patient care and the impact this has on the quality of care. Equally, little is known about how nurses enable such involvement. Previous studies have focused on settings such as critical care and paediatrics where relatives' involvement as advocates is mostly acknowledged and accepted. DESIGN: The study used a qualitative ethnographic approach based on an interpretive paradigm. METHODS: Data collection was carried out in medical settings in two major hospitals: one in Australia and another in Saudi Arabia. Data were collected by observations and interviews over a 6-month period, with 3 months spent in each setting. RESULTS: In both fields, relatives and nurses faced ongoing ambiguity about the role relatives should play in the hospital environment. Nurses were challenged by the unpredictability of relatives' participation in patient care. The nurses' fear of taking responsibility and uncertainty about the relatives' role led them to take varied and individualised approaches to the involvement of relatives in patient care. Relatives were unclear about how to behave in the role; what the needs of patients were; and whether they were contributing positively to care and this resulted in frustration. CONCLUSION: The results show that ambiguity regarding the role of relatives led to problems in patient care such as safety concerns and conflict with nurses. RELEVANCE TO CLINICAL PRACTICE: This study identified the need for patients' relatives and nursing staff to more actively engage in negotiating and managing their respective roles in acute medical areas. This could be supported by the development and use of a set of principles or guidelines for nurses, relatives and patients regarding relatives' involvement in hospital care settings to reduce ambiguity for all involved.

Kangaroo Mother Care Induced Serum Oxytocin Facilitates Prolactin and IL-10 Among Emergency Cesarean Mothers.

Background: The rate of cesarean section is increasing from 15% to 40% in recent years. The type of delivery influences the hormonal, emotional and mental health of the mother, which correlates positively or negatively with the health benefits of the newborn. There have been many published studies on kangaroo mother care for mothers undergoing elective cesarean section, but there is still a lack of understanding about emergency cesarean section. Objective: This study aimed to evaluate the benefits of KMC practice for mothers undergoing emergency cesarean section in terms of hormone levels such as oxytocin, cortisol, prolactin, interleukin-6 and interleukin-10. Methods: This retrospective analysis used remnant serum (KMC group = 16; control group = 9), and clinical data such as KMC practice (15-30 minutes three or four times daily until discharge), breastfeeding initiation time, feeding time, crying time and hospital stay were extracted from the electronic database. All hormone and cytokine expressions were quantitatively determined by ELISA. Comparisons within and between groups were performed using appropriate statistical tests. Results: In the KMC group, increased levels of the hormone oxytocin significantly reduced cortisol and IL-6 and negatively influenced prolactin and IL-10 levels. The elevated prolactin facilitates overall lactation behaviour, of which 64% reported breastfeeding directly at the breast. The cytokine analysis revealed a reduction in pro-inflammatory cytokines and thereby an improved wound healing was seen in the KMC group. Conclusion: These quantitative results strongly encourage the use of KMC for mothers undergoing emergency cesarean section. These simple yet effective breastfeeding strategies promote maternal and infant health, which can reduce medication use.

Neuroprotective effects of riluzole in Alzheimer's disease: A comprehensive review.

BACKGROUND: Despite several hundred clinical trials of drugs that initially showed promise, there has been limited clinical improvement in Alzheimer's disease (AD). This may be attributed to the existence of at least 25 abnormal cellular pathways that underlie the disease. It is improbable for a single drug to address all or most of these pathways, thus even drugs that show promise when administered alone are unlikely to produce significant results. According to previous studies, eight drugs, namely, dantrolene, erythropoietin, lithium, memantine, minocycline, piracetam, riluzole, and silymarin, have been found to target multiple pathways that are involved in the development of AD. Among these drugs, riluzole is currently indicated for the treatment of medical conditions in both adult patients and children and has gained increased attention from scientists due to its potential in the excitotoxic hypothesis of neurodegenerative diseases. OBJECTIVE: The aim of this study was to investigate the effects of drugs on AD based on cellular and molecular mechanisms. METHODS: The literature search for this study utilized the Scopus, ScienceDirect, PubMed, and Google Scholar databases to identify relevant articles. RESULTS: Riluzole exerts its effects in AD through diverse pathways including the inhibition of voltage-dependent sodium and calcium channels, blocking AMPA and NMDA receptors and inhibiting the release of glutamic acid release and stimulation of EAAT1-EAAT2. CONCLUSION: In this review article, we aimed to review the neuroprotective properties of riluzole, a glutamate modulator, in AD, which could benefit patients with the disease.

A glimpse into let-7e roles in human disorders; friend or foe?

MicroRNAs (miRNAs) have been linked to abnormal expression and regulation in a number of diseases, including cancer. Recent studies have concentrated on miRNA Let-7e's significance in precision medicine for cancer screening and diagnosis as well as its prognostic and therapeutic potential. Differential let-7e levels in bodily fluids have the possibility to enable early detection of cancer utilizing less-invasive techniques, reducing biopsy-related risks. Although Let-7e miRNAs have been described as tumor suppressors, it is crucial to note that there exists proof to support their oncogenic activity in vitro and in in vivo. Let-7e's significance in chemo- and radiation treatment decisions has also been demonstrated. Let-7e can also prevent the synthesis of proinflammatory cytokines in a number of degenerative disorders, including musculoskeletal and neurological conditions. For the first time, an overview of the significance of let-7e in the prevention, detection, and therapy of cancer and other conditions has been given in the current review. Additionally, we focused on the specific molecular processes that underlie the actions of let-7e, more particularly, on malignant cells.

Childhood obesity risk increases with increased screen time: a systematic review and dose-response meta-analysis.

BACKGROUND: The role of screen time in promoting obesity among children has been reported in previous studies. However, the effects of different screen types and the dose-response association between screen time and obesity among children is not summarized yet. In the current meta-analysis we systematically summarized the association between obesity and screen time of different screen types in a dose-response analysis. METHODS: A systematic search from Scopus, PubMed and Embase electronic databases was performed. Studies that evaluated the association between screen time and obesity up to September 2021 were retrieved. We included 45 individual studies that were drawn from nine qualified studies into meta-analysis. RESULTS: The results of the two-class meta-analysis showed that those at the highest category of screen time were 1.2 times more likely to develop obesity [odds ratio (OR) = 1.21; confidence interval (CI) = 1.113, 1.317; I2 = 60.4%; P < 0.001). The results of subgrouping identified that setting, obesity status and age group were possible heterogeneity sources. No evidence of non-linear association between increased screen time and obesity risk among children was observed (P-nonlinearity = 0.310). CONCLUSION: In the current systematic review and meta-analysis we revealed a positive association between screen time and obesity among children without any evidence of non-linear association. Due to the cross-sectional design of included studies, we suggest further studies with longitudinal or interventional design to better elucidate the observed associations.

Dishevelled: An emerging therapeutic oncogene in human cancers.

Cancer is a multifaceted and complex disorder characterized by uncontrolled rates of cell proliferation and its ability to spread and attack other organs. Emerging data indicated several pathways and molecular targets are engaged in cancer progression. Among them, the Wnt signaling pathway was shown to have a crucial role in cancer onset and progression. Dishevelled (DVL) acts in a branch point of canonical and non-canonical Wnt pathway. DVL not only acts in the cytoplasm to inactivate the destruction complex of ß-catenin but is also transported into the nucleus to affect the transcription of target genes. Available data revealed that the expression levels of DVL increased in cell and clinical specimens of various cancers, proposing that it may have an oncogenic role. DVL promoted cell invasion, migration, cell cycle, survival, proliferation, 3D-spheroid formation, stemness, and epithelial mesenchymal transition (EMT) and it suppressed cell apoptosis. The higher levels of DVL is associated with the clinicopathological characteristic of cancer-affected patients, including lymph node metastasis, tumor grade, histological type, and age. In addition, the higher levels of DVL could be a promising diagnostic and prognostic biomarker in cancer as well as it could be a mediator in cancer chemoresistance to Methotrexate, paclitaxel, and 5-fluorouracil. This study aimed to investigate the underlying molecular mechanism of DVL in cancer pathogenesis as well as to explore its importance in cancer diagnosis and prognosis as well as its role as a mediator in cancer chemotherapy.

Validation of the online version of the sharenting evaluation scale (SES) in Iranian parents: Psychometric properties and concurrent validity.

INTRODUCTION: This study examines the psychometric properties of the online version of the sharenting evaluation scale (SES) with a sample of Iranian parents. METHODS: A sample population of 240 parents (25% fathers and 75% mothers) with an average age of 39.63 (standard deviation = 10.41) were selected by convenience sampling method and completed the Persian version of the SES online. RESULTS: Findings showed that concurrent validity of the SES with social comparison and social well being was within the acceptable range. The Cronbach's alpha coefficient for the SES was 0.92, and for the subscales of self-control, social behavior, and implications were, respectively, 0.84, 0.71, and 0.70, which indicated good internal consistency between the items. Confirmatory factor analysis supported the Persian version of this scale same as the English version. The Persian version of the SES demonstrated psychometric properties of validity and reliability within the acceptable range (α = .70 and .84). In the present study, the results of convergent validity showed that there is a positive and significant relationship between sharing and constructs, such as social comparison, self-control, implications, and social behaviors, but no significant relationship was found between social well being and sharing. CONCLUSIONS: Persian version of the SES is a suitable scale to measure the degree to which parents share their children's sensitive content on the Internet and social media.

Investigating the effect of pregabalin on postoperative pain in non-emergency craniotomy.

BACKGROUND: Surgical procedures performed in the suboccipital and subtemporal regions are associated with severe pain. The present study was designed to determine pregabalin's effect on postoperative pain in elective craniotomy. METHOD: This double-blind prospective randomized clinical trial was conducted on 50 patients aged 20-60 with ASA classifications I and II. The patients who qualified for elective craniotomies were split into intervention (two capsules =300 mg pregabalin) and control groups (two capsule starch). Patients were also assessed at recovery, 2, 6, 12, and 24 h after surgery for their pain and level of sedation. Data were analyzed by SPSS software version 23, and a P-value ≤ 0.05 was considered significant. RESULTS: The mean pain score in the intervention group was lower than the control group at recovery (p = 0.224), 2 h (p = 0.001), 6 h (p = 0.011), and 12 h (p = 0.032) after surgery. The methadone consumption in the control group was significantly higher than the intervention group (p < 0.05). There was no significant difference between the two groups regarding the level of sedation (p > 0.05). The mean heart rate at induction (p = 0.01), 15 min (p = 0.01), 30 min (p = 0.025), recovery (p = 0.031), and 2 h (p = 0.021) after surgery and the MAP at recovery, 2 h, and 6 h after surgery was significantly lower than the control group (p = 0.029), (p = 0.013), and (p = 0.038), respectively. CONCLUSION: Our investigation demonstrated the effectiveness of pregabalin two hours before surgery on decreasing postoperative pain and analgesic consumption without disturbance in neurological examinations and any specific adverse effects.

Empowering Self-Efficacy by Using Patient Empowerment among Chronic Obstructive Pulmonary Disease: Pre-Post-Test Study.

Patient empowerment is increasingly acknowledged as a milestone of high-quality patient-centered care. This study was conducted using COPD Self-Efficacy Scale to determine the effectiveness of the patient empowerment intervention program among chronic obstructive pulmonary disease patients on self-efficacy. We employed an interventional design with a pre-test and post-test. Sixty COPD patients comprised the final sample of the study. The current study revealed significant improvement in overall self-efficacy factors among most participants. Statistically significant positive correlations were found between the total self-efficacy post-empower intervention model scores concerning age, sex, work, educational level, and marital status. The study's findings revealed that the patient empowerment intervention program positively affected COPD patients' self-efficacy.

An in vitro investigation of the apoptosis-inducing activity of corosolic acid in breast cancer cells.

Objectives: Breast cancer is the most prevalent cancer among females with different molecular subtypes. Corosolic acid is a pentacyclic triterpenoid with anti-cancer properties. Materials and Methods: The MTT assay was used to assess the cytotoxic activity of corosolic acid on MDA-MB-231 and MCF7 cell lines. To determine the apoptotic cells, the flow cytometry technique was utilized. The expression levels of apoptosis-related genes and proteins were quantified using quantitative real time-PCR (qRT-PCR) and Western blotting methods. The activity of caspase enzymes was measured by spectrophotometry. Results: Corosolic acid significantly inhibited the proliferation of both cell lines compared with controls. This agent markedly induced apoptosis in MDA-MB-231 cells but did not affect MCF7 cells compared with controls. Treating the MADA-MB-231 and MCF7 cell lines with corosolic acid showed an inducing effect on apoptosis-associated caspases, including Caspase-8, 9, and -3, in MADA-MB-231 cells with no effect on apoptotic markers in MCF7 cells. Further experiments uncovered corosolic acid-induced apoptosis in MADA-MB-231 cells by decreasing the expression of the phosphorylated form of JAK2 and STAT3 proteins. Conclusion: The present data suggested that corosolic acid is an apoptosis-inducing phytochemical in triple-negative breast cancer MADA-MB-231 cells. Also, corosolic acid triggered apoptosis in these cells by stimulating both pathways of apoptosis and inhibiting the JAK/STAT signaling. Furthermore, corosolic acid was found to inhibit MCF7 cell proliferation by a non-apoptotic mechanism.

Current Trends in Nanomaterials-Based Electrochemiluminescence Aptasensors for the Determination of Antibiotic Residues in Foodstuffs: A Comprehensive Review.

Veterinary pharmaceuticals have been recently recognized as newly emerging environmental contaminants. Indeed, because of their uncontrolled or overused disposal, we are now facing undesirable amounts of these constituents in foodstuff and its related human health concerns. In this context, developing a well-organized environmental and foodstuff screening toward antibiotic levels is of paramount importance to ensure the safety of food products as well as human health. In this case, with the development and progress of electric/photo detecting, nanomaterials, and nucleic acid aptamer technology, their incorporation-driven evolving electrochemiluminescence aptasensing strategy has presented the hopeful potentials in identifying the residual amounts of different antibiotics toward sensitivity, economy, and practicality. In this context, we reviewed the up-to-date development of ECL aptasensors with aptamers as recognition elements and nanomaterials as the active elements for quantitative sensing the residual antibiotics in foodstuff and agriculture-related matrices, dissected the unavoidable challenges, and debated the upcoming prospects.
