    Abstract Onion (Allium cepa L) varieties grow at different latitudes. Onions need cool temperatures in the early stages of growth, and high temperatures and long days during bulbing. Sowing of seed in autumn, winter, and early spring results in more leaf growth and subsequently higher bulb yield than sowing in late-spring and summer. Onion varieties show different reactions to temperature and day length. Short-day varieties need shorter day lengths and low temperatures for bulb induction compared to long-day varieties. As the required minimum day length of an onion variety is met with increasing temperatures, bulbs will be initiated. Short-day varieties reached the bulbing phase at day lengths of 11–12 h. Cultivation of short-day varieties originating from low and equatorial latitudes in areas with higher latitudes resulted in early maturity. All onion varieties, regardless of photoperiod requirements, require low temperatures in the early growing season and seedling stage. Cultivars with similar photoperiod requirements in terms of morphological and genetic traits are located in different groups. Carbohydrates are transferred from leaves to bulbs over long days and during the bulbing stage. There is a close relationship between sugar and flowering genes like AcFT2. Region, variety, and genetics of varieties influence onion bulbing.

    Abstract Background: Clarifying the dimensions and characteristics of obstetric telephone triage is important in improving the quality of services in the health system because researchers can evaluate the effectiveness of treatment, care and diagnostic measures in the form of obstetric telephone triage by developing a guideline. Therefore, this study aimed to design an Obstetric Telephone Triage Guideline (OTTG) using a mixed-method study.
    Methods: The present study was carried out using an exploratory sequential mixed method study in two qualitative and quantitative phases. An inductive-deductive approach was also used to determine the concept of obstetric telephone triage. In this respect, a qualitative study and a literature review were used in the inductive and deductive stages, respectively. Moreover, the validity of the developed guideline was confirmed based on experts' opinions and results of the AGREE II tool.
    Results: The guideline included the items for evaluating the severity of obstetric symptoms at five levels including "critical", "urgent", "less urgent", "no urgent", and "recommendations". The validity of the guideline was approved at 96%, 95%, 97%, 95%, 93%, and 100% for six dimensions of AGREE II including scope and purpose, stakeholder involvement, the rigor of development, clarity of presentation, applicability, and editorial independence, respectively.
    Conclusion: The OTTG is a clinically comprehensive, easy-to-use, practical, and valid tool. This guideline is a standardized tool for evaluating the severity of symptoms and determining the urgency for obstetrics triage services. By using this integrated and uniform guideline, personal biases can be avoided, leading to improved performance and ensuring that patients are not overlooked. Additionally, the use of OTTG promotes independent decision-making and reduces errors in triage decision-making.

    Abstract Background: Men experiencing infertility encounter numerous problems at the individual, family, and social levels as well as quality of life (QOL). This study was designed to investigate the QOL of men experiencing infertility through a systematic review.
    Materials and methods: This systematic review was conducted without any time limitation (Retrieval date: July 1, 2023) in international databases such as Scopus, Web of Science, PubMed, and Google Scholar. The search was performed by two reviewers separately using keywords such as QOL, infertility, and men. Studies were selected based on inclusion and exclusion criteria. The quality of the articles were evaluated based on the Newcastle-Ottawa Scale. In the initial search, 308 studies were reviewed, and after removing duplicates and checking the title and abstract, the full text of 87 studies were evaluated.
    Results: Finally, 24 studies were included in the final review based on the research objectives. Based on the results, men's QOL scores in different studies varied from 55.15 ± 13.52 to 91.45 ± 13.66%. Of the total reviewed articles, the lowest and highest scores were related to mental health problems and physical dimensions, respectively.
    Conclusion: The reported findings vary across various studies conducted in different countries. Analysis of the factors affecting these differences is necessary, and it is recommended to design a standard tool for assessing the quality of life of infertile men. Given the importance of the QOL in men experiencing infertility, it is crucial to consider it in the health system. Moreover, a plan should be designed, implemented and evaluated according to each country's contex to improve the quality of life of infertile men.

    Abstract Background: Considering ethical issues in midwifery care is essential for improving the quality of health services and the client's satisfaction. This study aimed to develop and validate the code of ethics for Midwives in Iran (ICEM).
    Materials and methods: This was a mixed sequential study that was performed in three phases including a qualitative study, a review, and the content validity assessment. The first phase was a qualitative study with a content analysis approach. The data were collected by conducting in-depth semi-structured individual interviews with 14 midwifery and ethics experts. The purposive sampling method was used to recruit the participants and sampling continued until data saturation. The data were analyzed using the conventional content analysis described by Graneheim and Lundman. Lincoln and Guba's criteria were used to confirm the trustworthiness of the data. Then, a narrative review of the selected national and international codes of ethics for Midwives was performed to complete the items of the ICEM. For validity assessment, the face and content validity of the items of ICEM was assessed by 15 experts to calculate the content validity ratio (CVR) and index (CVI).
    Results: Fourteen experts were interviewed in the qualitative phase, and 207 codes were extracted from a content analysis which were categorized into 23 sub-categories and 6 main categories. The extracted codes were considered as the items for ICEM that were completed by a review of the selected national and international code of ethics for Midwives. The content validity and ratio assessment of the items demonstrated an average CVI = 0.92 and CVR = 0.85. Then, the final version of ICEM was developed with 92 items in 6 domains about; 1) "professional Commitments" with 30 items; 2) "providing midwifery services to the client and her companions" with 26 items; 3) "relationship with colleagues" with 11 items; 4) "herself" with 6 items; 5) "education and research" with 8 items; and, 6) "management" with 11 items.
    Conclusion: ICEM was prepared with 92 items in six sections that facilitate its use for midwives who are working in the different fields of care, counseling, education, research, and management. In this new version of the ICEM, the items related to recent social-, scientific, and technical improvements were considered for providing ethical midwifery care.

    Abstract Background: Burn injuries are important medical problems that, aside from skin damage, cause a systemic response including inflammation, oxidative stress, endocrine disorders, immune response, and hypermetabolic and catabolic responses which affect all the organs in the body. The aim of this study was to determine the effect of coenzyme Q10 (CoQ10) supplementation on inflammation, oxidative stress, and clinical outcomes in burn patients.
    Methods: In a double-blind placebo-controlled randomized clinical trial, 60 burn patients were randomly assigned to receive 100 mg CoQ10 three times a day (total 300 mg/day) or a placebo for 10 days. Inflammatory markers including erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), oxidative stress markers including total antioxidant capacity (TAC), malondialdehyde (MDA) and superoxide dismutase (SOD) activity, fasting blood glucose (FBG), blood urea nitrogen (BUN), creatinine, white blood cells (WBC), and body temperature were assessed as primary outcomes and albumin, prothrombin time (PT), partial thromboplastin time (PTT), international normalized ratio (INR), other hematological parameters, blood pressure, O
    Results: Fifty-two participants completed the trial. CRP and ESR levels were not significantly different between CoQ10 and placebo groups at the end of the study (P = 0.550 and P = 0.306, respectively). No significant differences between groups were observed for TAC (P = 0.865), MDA (P = 0.692), and SOD activity (P = 0.633) as well. Administration of CoQ10 resulted in a significant increase in albumin levels compared to placebo (P = 0.031). There was no statistically significant difference between the two groups in other measured outcomes (P > 0.05).
    Conclusion: Results showed that in patients with burn injury, CoQ10 administration had no effect on inflammatory markers and oxidative stress, although serum albumin levels were improved after supplementation. Further studies with albumin as the primary outcome are needed to confirm this finding.

    Abstract Alzheimer's disease (AD) is one of the most common forms of neurodegenerative diseases. Apolipoprotein E4 (ApoE4) is the main genetic risk factor in the development of late-onset AD. However, the exact mechanism underlying ApoE4-mediated neurodegeneration remains unclear. We utilized Drosophila melanogaster to examine the neurotoxic effects of various human APOE isoforms when expressed specifically in glial and neural cells. We assessed impacts on mitochondrial dynamics, ER stress, lipid metabolism, and bio-metal ion concentrations in the central nervous system (CNS) of the transgenic flies. Dachshund antibody staining revealed a reduction in the number of Kenyon cells. Behavioral investigations including ethanol tolerance and learning and memory performance demonstrated neuronal dysfunction in APOE4-expressing larvae and adult flies. Transcription level of marf and drp-1 were found to be elevated in APOE4 flies, while atf4, atf6, and xbp-1 s showed down regulation. Enhanced concentrations of triglyceride and cholesterol in the CNS were observed in APOE4 transgenic flies, with especially pronounced effects upon glial-specific expression of the gene. Spectrophotometry of brain homogenate revealed enhanced Fe

    Abstract The evaluation of A. cepa biodiversity provides onion breeders with great prospects to obtain plants with high resistance to environmental factors, remarkable yield, and product quality. Genetic diversity assessment of a collection of nine short- and long-day onion landraces and varieties originated from different Iranian regions, using ISSR markers and UPGMA dendrograms, was carried out for the first time. Short-day landraces (Sarze, Sarkoreh, and Kerman) originated from low latitude and short-day hybrids (Mirela and Soberana) demonstrated high genetic similarity, in terms of physiological responses to day length and temperature during the crop cycle and bulbing stage initiation. Contrarily, high latitude landraces (Azarshahr, White Gorgan, Kurdistan, and Esfahan) showed low biometrical, agronomic and genetic similarity with commercial short-day onions. Specific differences in morphological reactions between these two groups displayed diverse responses of plants to day length and temperature. Long- and short-day cultivars displayed significant differences in the dynamics of leaf and scale number, leaf and root length, dry and fresh weight, and bulbing ratio and bulb diameter, which were in accordance with ISSR data. The local landraces Azarshahr, Kurdistan, and Esfahan had high antioxidant status, suggesting high prospects for their utilization as an alternative to foreign F₁ hybrid varieties.
