Thyroid cancer cell metabolism: A glance into cell culture system-based metabolomics approaches.

Thyroid cancer is the most common malignancy of the endocrine system and the seventh most prevalent cancer in women worldwide. It is a complex and diverse disease characterized by heterogeneity, underscoring the importance of understanding the underlying metabolic alterations within tumor cells. Metabolomics technologies offer a powerful toolset to explore and identify endogenous and exogenous biochemical reaction products, providing crucial insights into the intricate metabolic pathways and processes within living cells. Metabolism plays a central role in cell function, making metabolomics a valuable reflection of a cell's phenotype. In the OMICs era, metabolomics analysis of cells brings numerous advantages over existing methods, propelling cell metabolomics as an emerging field with vast potential for investigating metabolic pathways and their perturbation in pathophysiological conditions. This review article aims to look into recent developments in applying metabolomics for characterizing and interpreting the cellular metabolome in thyroid cancer cell lines, exploring their unique metabolic characteristics. Understanding the metabolic alterations in tumor cells can lead to the identification of critical nodes in the metabolic network that could be targeted for therapeutic intervention.

The Effect of Spiritual Group Therapy on the Quality of Life and Empowerment of Women with Breast Cancer: A Randomized Clinical Trial in Iran.

This randomized clinical trial was carried out on 74 women with breast cancer between May 2015 and April 2016 in the south of Iran. The patients were selected using a simple sampling method and randomly divided into an intervention (n = 30) and a control (n = 37) group. Five spiritual therapy sessions were conducted for the intervention group. Each session lasted one hour. The quality of life and empowerment of the patients were measured before and one month after the intervention. To collect data, four instruments were used, including a demographic information form, the European Organization for Research and Treatment of Cancer QOL questionnaire Cancer-30 (EORTC QLQ C-30), EORTC QLQ Breast-23 (EORTC QLQ-BR23), and the Cancer Empowerment Questionnaire (CEQ). After the intervention, a difference was observed between the groups concerning the mean score of general health (P = 0.016) and emotional function (P = 0.029), but there was no significant difference between the groups concerning the mean score of empowerment (P = 0.62). Thus, it appears that spiritual group therapy can improve the quality of life of this group of patients.IRCT registration number: IRCT 2014050417546N2.

The application of nano-hydrogels and hydrogels in wound dressings.

Wounds and the healing process are one of the main concerns of medical science today. A wound is any loss of integrity, or rupture of the layers of skin (epidermis, dermis, and hypodermis) or subcutaneous tissue caused by physical factors (surgical incision, trauma, pressure, and gunshot wounds) or chemical factors (acid burns). It is observed that soft tissue, muscle, or bone is involved in occurrences of wounds. Lesions and fractures of the skin surface necessitate medical attention, wherein dressings expedite the healing process by establishing a physical barrier between the wound and the external environment, thereby preventing further injury or infection. Hydrogel dressings create a moist environment that facilitates common healing steps, such as granulation hyperplasia, epidermal repair, and removal of excess dead tissue. The limited adhesion of the hydrogel and the hydrated wound bed allows for easy removal of the dressing without secondary damage, thereby significantly reducing the discomfort and risk of infection during dressing changes. These modern, wet dressings foster a moist healing environment by absorbing excess inflammatory secretions and allowing proper passage of steam and air, which expedites the healing process. In this analysis, the utilization of hydrogels as wound dressings is briefly presented.

A Decision-Aware Ambient Assisted Living System with IoT Embedded Device for In-Home Monitoring of Older Adults.

Older adults' independent life is compromised due to various problems, such as memory impairments and decision-making difficulties. This work initially proposes an integrated conceptual model for assisted living systems capable of providing helping means for older adults with mild memory impairments and their caregivers. The proposed model has four main components: (1) an indoor location and heading measurement unit in the local fog layer, (2) an augmented reality (AR) application to make interactions with the user, (3) an IoT-based fuzzy decision-making system to handle the direct and environmental interactions with the user, and (4) a user interface for caregivers to monitor the situation in real time and send reminders once required. Then, a preliminary proof-of-concept implementation is performed to evaluate the suggested mode's feasibility. Functional experiments are carried out based on various factual scenarios, which validate the effectiveness of the proposed approach. The accuracy and response time of the proposed proof-of-concept system are further examined. The results suggest that implementing such a system is feasible and has the potential to promote assisted living. The suggested system has the potential to promote scalable and customizable assisted living systems to reduce the challenges of independent living for older adults.

Differences in the child, mother, and nurses' pain score measurements during pediatric venipuncture.

BACKGROUND: Self-reporting is the gold standard for measuring pain in adult pain management; however, this issue is unique and different in children. Accurate pain assessment for the appropriate management of children's pain is important. PURPOSE: This study was conducted to assess the pain level by the child, mother, and nurse during intravenous line insertion in preschool children, candidates for surgery in Tabriz Children's Hospital. DESIGN AND METHODS: This is descriptive observational study. A total of 140 eligible children were included in the study using convenience and sequential methods. The intravenous line was inserted by an experienced nurse and pain assessment was performed by the child, mother, and nurse immediately after procedure, using the Wong-Baker face scale (WBFS). The data were analyzed through descriptive statistics and repeated measures ANOVA test using SPSS version 13 software. RESULTS: The difference between child-mother and nurse-mother mean scores was not statistically significant; however, there was a statistically significant difference between the score measured by the child and the nurse (P = 0.017). CONCLUSION: The children's pain assessment score during venipuncture was higher than that of mothers and nurses. The mothers' score was more closely related to the children's score. As a result, a mother's assessment can be considered a reliable estimation of proper pain management in young children and mothers can act as a moderator and actualize the nurses' score. Consequently, establishing a three-way communication between mother, child, and nurses is necessary to precisely estimate the child's actual pain and take appropriate measures to reduce it.

Silent Mourning: Infant Death and Caring for Iranian Parents Under the Influence of Religious and Socio-cultural Factors.

Despite all the advances in healthcare technology and all the care services in the field of neonates, many infants die in neonatal intensive care units (NICUs). This qualitative study investigated socio-cultural factors influencing the care for bereaved parents in three main NICUs of northwest Iran between March 2018 and April 2019. The purposeful sampling method with the maximum variation was used, and data collection was continued until obtaining rich data to answer the research question. Twenty-eight interviews were conducted with 26 healthcare providers. The thematic analysis method was applied to analyze the data, and two main themes, including "Religious context as a restriction on the parental involvement in the infant's end-of-life care" and the "Socio-cultural challenges of the grieving process among parents", were generated accordingly. The religious and socio-cultural contexts in the NICUs of Iran are a restriction to the presence of parents at their infants' end-of-life phase, and health care providers are less inclined to have parents in the NICU at the time of infant death.

Caring for the Bereaved Parents in the NICU: Fathers-The Missing Piece of the Puzzle.

PURPOSE: Grief after infant death is a common experience of bereaved parents often seen in the neonatal intensive care unit (NICU). The NICU staff tend to focus more on the mother's support, and fathers are often not treated equally as mothers. This study aimed to investigate the circumstance of caring for parents facing infant death in NICUs. METHODS: Twenty-eight face-to-face in-depth interviews were conducted between March 2018 and April 2019 in the northwest of Iran. Participants were selected via purposive sampling. An inductive thematic approach was used for data analysis. RESULTS: Three main themes and 7 subthemes were extracted. The main themes were: "the father-the missing piece of the puzzle in the mourning process," "restricted presence of fathers due to religious and traditional beliefs," and "the father-the patience stone." CONCLUSION: Due to cultural-religious backgrounds, traditional beliefs, structural problems, and organizational restrictions, fathers in NICUs do not receive adequate support, particularly when faced with their infant's death. Bereaved fathers need to receive more support and attention from healthcare providers. Therefore, there is a need for changing the care providers' attitudes regarding the role of fathers and the quality of support that fathers should receive in the Muslim populations.

Global identification of long non-coding RNAs involved in the induction of spinach flowering.

BACKGROUND: Spinach is a beneficial annual vegetable species and sensitive to the bolting or early flowering, which causes a large reduction in quality and productivity. Indeed, bolting is an event induced by the coordinated effects of various environmental factors and endogenous genetic components. Although some key flowering responsive genes have been identified in spinach, non-coding RNA molecules like long non-coding RNAs (lncRNAs) were not investigated yet. Herein, we used bioinformatic approaches to analyze the transcriptome datasets from two different accessions Viroflay and Kashan at two vegetative and reproductive stages to reveal novel lncRNAs and the construction of the lncRNA-mRNA co-expression network. Additionally, correlations among gene expression modules and phenotypic traits were investigated; day to flowering was chosen as our interesting trait. RESULTS: In the present study, we identified a total of 1141 lncRNAs, of which 111 were differentially expressed between vegetative and reproductive stages. The GO and KEGG analyses carried out on the cis target gene of lncRNAs showed that the lncRNAs play an important role in the regulation of flowering spinach. Network analysis pinpointed several well-known flowering-related genes such as ELF, COL1, FLT, and FPF1 and also some putative TFs like MYB, WRKY, GATA, and MADS-box that are important regulators of flowering in spinach and could be potential targets for lncRNAs. CONCLUSIONS: This study is the first report on identifying bolting and flowering-related lncRNAs based on transcriptome sequencing in spinach, which provides a useful resource for future functional genomics studies, genes expression researches, evaluating genes regulatory networks and molecular breeding programs in the regulation of the genetic mechanisms related to bolting in spinach.

Prevalence and correlates of chronic fatigue syndrome and post-traumatic stress disorder after the outbreak of the COVID-19.

As the SARS-COV-2 becomes a global pandemic, many researchers have a concern about the long COVID-19 complications. Chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME) is a persistent, debilitating, and unexplained fatigue disorder. We investigated psychological morbidities such as CFS and post-traumatic stress disorder (PTSD) among survivors of COVID-19 over 6 months. All COVID-19 survivors from the university-affiliated hospital of Tehran, Iran, were assessed 6 months after infection onset by a previously validated questionnaire based on the Fukuda guidelines for CFS/EM and DSM-5 Checklist for PTSD (The Post-traumatic Stress Disorder Checklist for DSM-5 or PCL-5) to determine the presence of stress disorder and chronic fatigue problems. A total of 120 patients were enrolled. The prevalence rate of fatigue symptoms was 17.5%. Twelve (10%) screened positive for chronic idiopathic fatigue (CIF), 6 (5%) for CFS-like with insufficient fatigue syndrome (CFSWIFS), and 3 (2.5%) for CFS. The mean total scores in PCL-5 were 9.27 ± 10.76 (range:0-44), and the prevalence rate of PTSD was 5.8%. There was no significant association after adjusting between CFS and PTSD, gender, comorbidities, and chloroquine phosphate administration. The obtained data revealed the prevalence of CFS among patients with COVID-19, which is almost similar to CFS prevalence in the general population. Moreover, PTSD in patients with COVID-19 is not associated with the increased risk of CFS. Our study suggested that medical institutions should pay attention to the psychological consequences of the COVID-19 outbreak.

Multiple species delimitation approaches applied to the avian lark genus Alaudala.

Species delimitation has advanced from a purely phenotypic exercise to a branch of science that integrates multiple sources of data to identify independently evolving lineages that can be treated as species. We here test species limits in the avian Lesser Short-toed Lark Alaudala rufesens-Sand Lark A. raytal complex, which has an intricate taxonomic history, ranging from a single to three recognised species, with different inclusiveness in different treatments. Our integrative taxonomic approach is based on a combination of DNA sequences, plumage, biometrics, songs, song-flights, geographical distributions, habitat, and bioclimatic data, and using various methods including a species delimitation program (STACEY) based on the multispecies coalescent model. We propose that four species should be recognised: Lesser Short-toed Lark A. rufescens (sensu stricto), Heine's Short-toed Lark A. heinei, Asian Short-toed Lark A. cheleensis and Sand Lark A. raytal. There is also some evidence suggesting lineage separation within A. cheleensis and A. raytal, but additional data are required to evaluate this. The species delimitation based on STACEY agrees well with the non-genetic data. Although computer-based species delimitation programs can be useful in identifying independently evolving lineages, we stress that whenever possible, species hypotheses proposed by these programs should be tested by independent, non-genetic data. Our results highlight the difficulty and subjectivity of delimiting lineages and species, especially at early stages in the speciation process.

Molecular Phylogeny of the Subgenus Karstomys Reveals Genetic Signature of Post-Glacial Colonization of Apodemus mystacinus (Rodentia: Muridae) in the Zagros Mountains from Different Refugia.

Eastern broad-toothed field mouse, Apodemus mystacinus, is a rocky habitat dwelling rodent distributed in Asia Minor, the Levant, the Caucasus, and the Zagros Mountains. In this study, we investigated the phylogenetic relationship between different populations of A. mystacinus throughout its range, based on the mitochondrial cytb marker. Phylogenetic analyses revealed the existence of five separately evolving lineages within A. mystacinus, of which two previously unrecognized lineages were identified in the Zagros Mountains and the Levant. Divergence between two major clades of the subgenus Karstomys, corresponding to A. mystacinus and Apodemus epimelas, is inferred to coincide with the Messinian Salinity Crisis (Late Miocene), whereas the splits between major lineages of A. mystacinus are inferred to have occurred during the Pleistocene. Colonization of the Zagros may have occurred from different refugia via eastward migration of the Turkish population and then again by a more recent colonization from the Caucasus, after reopening of the land corridor between the Caucasus and the Zagros Mountains during the Holocene drought.

Associations of BCL2 CA-Repeat Polymorphism and Breast Cancer Susceptibility in Isfahan Province of Iran.

BCL2 apoptosis regulator (BCL2) is a cause of tumorigenesis whose CA-repeat promoter polymorphisms has inconsistent association with various types of cancers. The association of BCL2 polymorphism with breast cancer was investigated in the Isfahan province of Iran. PCRamplification of the CA-repeat was followed by polyacrylamide gel electrophoresis and direct sequencing for 120 breast cancer women and an equal number of corresponding healthy control individuals. Seven different alleles, ranging from 11 to 17 CA-repeats were observed. Short alleles with 11 to 14 repeats were protective (OR 0.363, P = 0.001), but large alleles with 15 to 17 repeats were threatening against breast cancer development (OR 2.780, P = 0.001). Accordingly, genotypes with large alleles showed a higher risk of breast cancer development (OR 3.400, P = 0.004). ERS1\ERBB2 positive breast cancer patients, but not PGRpositive ones, showed protection against breast cancer (OR 0.405, OR 0.346 respectively). In conclusion, women with at least one large allele of BCL2 were 3.4 times at higher risk of breast cancer development in the Isfahan province of Iran.

Distress tolerance and special alcohol metacognitions behave differently in the association of negative affect with alcohol-related patterns in men with problematic alcohol use in the abstinence phase.

Negative affect may be related to alcohol-related patterns (e.g., craving and problematic alcohol use). Distress intolerance and positive and negative alcohol-related metacognitions may be underlying mechanisms in this link. This study aimed to evaluate the effect of negative affect including depressive, anxious, and stress symptoms on alcohol craving and problematic alcohol use via the paths of distress tolerance and both positive and negative alcohol-related metacognitions. Three hundred men with problematic alcohol use during the abstinence phase completed psychological and clinical measures. Results showed that craving and negative alcohol metacognitions mediated the relationship between negative affect and problematic alcohol use. Negative affect had a direct and positive effect on craving and indirect effect via distress intolerance and positive alcohol metacognitions. In turn, distress intolerance and positive alcohol metacognitions indirectly and positively affected problematic alcohol use via craving. The study indicates that distress tolerance and distinct alcohol metacognitions may be differently related to various patterns of alcohol-related problems, such that alcohol drinkers with high levels of negative affect, distress intolerance, and positive alcohol metacognitions show higher levels of craving, while high negative affect in relation to high negative alcohol metacognitions and alcohol craving is related to the perpetuation of alcohol use or problematic alcohol use.

Runx2 silencing promotes adipogenesis via down-regulation of DLK1 in chondrogenic differentiating MSCs.

BACKGROUND: For cartilage regeneration, stem cells are a promising cell source; however, even the advances made in the differentiation of stem cells into precursor-differentiated cartilage cells have not been successful with respect to reprograming these cells to achieve complete differentiation and fully functioning cells until now. Previous findings suggest that Runx2 plays a major role in chondrocyte differentiation and maturation. Although targeting Runx2 has enhanced some chondrocyte properties, the adipogenic lineage shift has eventually occurred in these cells. The present study mainly aimed to reveal the mechanism of this adipogenesis. METHODS: To create inducible artificial shRNA-miR expressing vectors, the designed short hairpin RNAs (shRNAs) were inserted into the pri-mir-30 backbone, cloned into lentiviral pLVET-Tet-on, and transducted into mesenchymal stem cells (MSCs). Runx2 gene was silenced in MSCs either for 1 week or 4 weeks and cultured in the chondrogenic medium. At days 7, 14 and 28, cells were harvested, and chondrogenesis, adipogenesis and hypertrophic states were examined using histochemical staining and a real-time polymerase chain reaction assay. RESULTS: The results showed that the designed shRNA-miR effectively targeted Runx2 in mRNA and protein levels. Chondrogenic markers were up-regulated in constantly silenced Runx2 group; however, adipogenic markers and fat droplets appeared gradually. DLK1 gene was also significantly down-regulated in this group, and overexpression of DLK1 abrogated adipogenesis in the Runx2 targeted group. CONCLUSIONS: Based on these results, it can be concluded that DLK1 is responsible for the lineage shift in Runx2 targeted chondrogenic differentiating MSCs.

Comparison of the Effect of Massage and EMLA Cream on Children's Physiological Indices During Venipuncture: A Factorial Clinical Trial.

PURPOSE: The aim of this study was to identify the effect of massage, EMLA cream, and the combination of these two methods on changes in physiological indices because of pain caused by intravenous line insertion in preschool children. DESIGN: A four-group randomized nonblinded clinical trial with factorial design. METHODS: In total, 140 eligible 3- to 6-year-old children entered the study in Tabriz Children's Hospital in 2017 and were randomly allocated to four groups (EMLA cream, massage, combination of the two, and control). Physiological responses were measured before and immediately after interventions in all groups. Data were collected and analyzed using SPSS version 19. FINDINGS: Comparison of the physiological indices changes caused by pain between groups showed that changes in children's heart rate (HR) and respiratory rate (RR) in the EMLA group and in the combined-method group were statistically significant (P < .05). No significant differences were found in systolic blood pressure and oxygen saturation (SPo2) between the four groups. CONCLUSIONS: Results indicated that EMLA cream was more effective than massage and a combination of EMLA and massage in reducing an increase in the HR and RR caused by pain in children. Massage alone was not effective in significantly lowering the children's increased physiological indices such as the HR and RR, and it seems the effectiveness of massage is more noticeable in conjunction with EMLA cream.

Fathers: The Lost Ring in the Chain of Family-Centered Care: A Phenomenological Study in Neonatal Intensive Care Units of Iran.

BACKGROUND: The basic principles of family-centered care in neonatal intensive care unit (NICU) include the unlimited presence of parents and their participation in infant's care. Nurses play a central role in encouraging parental attachment with their infant. PURPOSE: This study was carried out with the aim of understanding NICU nurses' lived experiences of family participation in family-centered care. METHODS: This interpretative phenomenological study was conducted on the basis of Heideggerian philosophy. The data were collected using semistructured interviews and field notes and analyzed through the 7-stage Diekelmann, Allen, and Tanner approach. FINDINGS: Two overarching themes emerged including "mother's centrality in the care chain" and "fathers; the lost ring in the care chain" each of which consisted of 3 and 4 subthemes, respectively. Interviews indicated that in Iran's NICUs, conditions for the presence of parents were appropriate for the mothers and they were encouraged to engage in family-centered care but the fathers' participation was limited due to traditional attitudes, cultural-religious background, and difficulties relating to the hospitals' organizational rules. IMPLICATIONS FOR PRACTICE: Fathers' participation in family-centered care seems to be enhanced through providing facilities, altering the organizational rules, attempting to modify traditional social attitudes, and educating parents and nurses. IMPLICATIONS FOR RESEARCH: Future research should explore the experience of mothers and fathers of infants in NICU in Iran to achieve a comprehensive understanding of their role in family-centered care.

Differential cell analysis in ovine bronchoalveolar lavage fluid: Effect of different sampling methods and seasons.

Background: Bronchoalveolar lavage (BAL) is a method for collecting the cellular and fluid components of the airway surface in the lungs. The assessment of differential cell profiles is potentially valuable in the diagnosis of pulmonary diseases, but there is no information about the normal BAL profiles in the Gezel breed. Aim: This study aimed to characterize the normal cryptologic findings of BAL with Gezel sheep. Methods: Twenty healthy sheep (15 females: 5 males, bodyweight: 55-65 kg) were sedated with xylazine (0.02-0.04 mg/kg IV). Two methods; the transtracheal bronchoalveolar lavage technique and the bronchoscopic bronchoalveolar lavage using a scope were evaluated. Sampling was performed in the summer and winter seasons. Results: Normal value (Mean ± SEM) for total cell, macrophage, lymphocyte, neutrophil, epithelial, and bronchial cells in BAL sampled in summer were (343.75 ± 30.23), ) 24.50 ± 2.62), (2.81 ± 0.51), (1.43 ± 0.88), and (3.12 ± 0.32), respectively. The normal values for the total cell, macrophage, lymphocyte, neutrophil, epithelial, and bronchial cells in BAL sampled in winter were (355.55 ± 37.67), (59.11 ± 4.30), (21.33 ± 3.10), (3.88 ± 1.07), (8.88 ± 3.78), and (6.33 ± 1.44), respectively. Conclusion: No significant change in the percentage of neutrophils was detected between seasons, although the percentages of bronchial and epithelial cells in winter were significantly high (p < 0.05). Except for the mentioned cases, neither the total cell number nor the percentage differential cell populations of BAL changed significantly (p < 0.05) in different sampling methods and seasons. Normal BAL profiles in the Gezel breed were determined and could be used in result interpretations. Also, both sampling methods can be used without significantly affecting the results.

The effects of purslane (Portulaca oleracea) and fennel (Foeniculum vulgare Mill) hydroalcoholic extracts on the functional parameters of human spermatozoa after vitrification.

OBJECTIVE: Reactive oxygen species (ROS) are produced during cryopreservation of human sperm and impair sperm function. Antioxidant compounds, such as fennel and purslane, reduce the damaging effects of ROS. This study aimed to evaluate motility parameters, plasma membrane integrity (PMI), mitochondrial membrane potential (MMP), intracellular ROS, and DNA damage to determine the optimum concentrations of hydroalcoholic extracts of fennel and purslane for human spermatozoa cryopreservation. METHODS: Twenty human sperm samples were used and divided into seven equal groups consisting of fennel hydroalcoholic extract (5, 10, and 15 mg/L), purslane hydroalcoholic extract (25, 50, and 100 mg/L), and no additive. RESULTS: Supplementation of 25 mg/L and 50 mg/L purslane extract and 10 mg/L fennel extract in cryopreservation extender significantly increased the motility and PMI of sperm with a significant reduction in intracellular ROS compared to control groups (p<0.05). A 50 mg/L concentration of purslane extract elevated progressive motility and MMP compared to the control group (p<0.05). No significant differences were seen for motion patterns and DNA damage of frozen-thawed human sperm in extender containing these extracts. CONCLUSION: The results showed that supplementation of 50 mg/L purslane extract and 10 mg/L fennel extract in semen cryopreservation extender has the potential to decrease intracellular ROS and subsequently elevate the motility and PMI of human sperm.

Effect of melatonin on male offspring testis and sperm parameters in BALB/c mice after exposing their mother to METHamphetamine during pregnancy and lactation.

Objectives: Methamphetamine (METH) is a psychostimulant that has harmful effects on all organs, the nervous system, cardiovascular system, and reproductive system. Since many METH consumers are young people of reproductive age, it poses a risk to the next generation of METH consumers. METH can pass through the placenta and is also secreted into breast milk. Melatonin (MLT) is the primary hormone of the pineal gland that regulates the circadian cycle, and it is also an antioxidant that can mitigate the effects of toxic substances. This study aims to investigate the protective effect of melatonin against the detrimental effects that METH has on the reproductive system of male newborns, whose mothers consumed METH during pregnancy and lactation. Materials and Methods: In the current study, 30 female adult balb/c mice were divided into three groups: control group, vehicle group that received normal saline, and the experimental group that received 5 mg/kg METH intraperitoneally during gestation and lactation. After lactation, the male offspring of each group were randomly divided into two subgroups, one of which received 10 mg/kg melatonin intragastrically for 21 days (corresponding to the lactation period of the mice) (METH-MLT) and the other did not (METH -D.W). After treatment, the mice were sacrificed and testicular tissue and epididymis were obtained for the following tests. Results: The diameter of seminiferous tubules, SOD activity, total Thiol groups concentration, catalase activity, sperm count, and PCNA and CCND gene expression were significantly increased in the METH-MLT group compared with the METH-DW. Apoptotic cells and MDA level ameliorated in the METH-MLT group compared with METH-D.W, and testicular weight had no notable change. Conclusion: The current study represents that consumption of METH during pregnancy and lactation can have adverse effects on the histological and biochemical factors of testis and sperm parameters of male newborns, which can be mitigated by taking melatonin after the end of the breastfeeding period.

Auraptene-induced cytotoxic effects in acute myeloid leukemia cell lines.

Acute myeloid leukemia is one of the most commonly identified hematological malignancies with poor prognosis. This research was planned to identify the cytotoxic effects of Auraptene on HL60 and U937 cell lines. The cytotoxic effects of Auraptene were measured by AlamarBlue assay (Resazurin) after 24- and 48-h treatments with different doses of Auraptene. The inductive effects of Auraptene on cellular oxidative stress were investigated by determining cellular ROS levels. The cell cycle progression and cell apoptosis were also evaluated by flow cytometry method. Our findings revealed that Auraptene decreased HL60 and U937 cellular proliferation by downregulation of Cyclin D1. Auraptene also induces cellular oxidative stress by upregulation of cellular ROS levels. Auraptene induces cell cycle arrest the early and late phases of apoptosis by upregulation of Bax and p53 proteins. Our data suggest that the anti-tumor function of Auraptene can be mediated by promoting apoptosis and cell cycle arrest and inducing cellular oxidative stress in HL60 and U937 cell lines. These results support that Auraptene may be used as a potent anti-tumor agent against hematologic malignancies in the further studies.
