A diallel of seven inbred clones of the domestic strawberry was evaluated for 5 variables and was compared with the standard cultivar Redcoat. For fruit yield, berry size, date of mid-harvest, and area covered by the clone, the Redcoat values were close to the mean of the diallel. Unexpectedly, all seedling crosses produced more than twice as many runners as did Redcoat.The additive component of variance was only 3.2 per cent for yield, but was 50.5, 83.0, 27.6, and 10.9 per cent for berry weight, mean date of harvest, runner number per clone, and area covered per clone respectively. Total fruit yield was significantly influenced by all of the other four variables, but the relationship was highly variable and did not present any consistent pattern. A cautious interpretation of results is required because of common parentage and inbreeding in the parental lines.The results of this study are in general agreement with similar studies at North Carolina and Ottawa, but all three of these studies gave quite different results from one in California using a parent-offspring regression method of analysis. It is suggested that the different methods of measuring genetic parameters may be as important in resolving this discrepancy as methods of culture, range of cultivars and climatic factors, which have been previously suggested.

Background: Coronavirus disease 2019 (COVID-19) is a life-threatening disease that has spread globally and received international concern. Iran is one of the countries severely affected by this pandemic, implementing social lockdown and restrictive strategies. According to Persian medicine, restrictions like quarantine have psychological and social consequences. Objectives: This study aimed to investigate the relationship between sleep quality and anger behaviors in Iran and compare it with Persian medicine viewpoints. Methods: In this cross-sectional study, 739 participants were interviewed in April 2020 in Shiraz, Iran. The questionnaire included the Pittsburgh Sleep Quality Index (PSQI), the Multidimensional Anger Inventory (MAI), and items on demographics, temperament, and the quarantine situation social factors. All participants completed the questionnaires willingly and were ensured of data confidentiality. Results: We found that 58.3% of the participants had low sleep quality. Females showed higher scores on anger and its related aspects (P < 0.05). In addition, people with lower education and income levels revealed higher anger scores (P < 0.05). Moreover, the mean scores of anger and its related factors were higher in participants with low sleep quality, higher sleep latency, daytime dysfunction, and experience of using sleep medications (P < 0.05). Also, after adjustment for demographics and other social factors, the mean scores of anger and all of its aspects were higher in those with a sleep disorder, use of sleep medications, and daytime dysfunction (P < 0.05). Conclusions: In conclusion, our findings illustrated that various factors, including low sleep quality, are associated with anger in individuals with the experience of home quarantine during the COVID-19 outbreak. The outcome is compatible with Persian medicine evidence.

Abstract In this paper, a fragile ecological area in the Western Tianshan National Nature Reserve of China was selected as the research region, and Picea schrenkiana, which is sensitive to climate change, was selected as the research object. The mean minimum temperature in the growing season of the previous year (May to September) was the main limiting factor for tree radial growth based on an analysis of the relationship between chronological series and climatic factors during 1959–2012 (r = –0.792, p < 0.05). Moreover, the relationship was stable, which showed that tree rings can be used as alternative materials for climate reconstruction. Therefore, the mean minimum temperature of the previous year in 1680–2012 was reconstructed, and the explained variance of the reconstruction equation was 62.7% (R2adj = 62.0%, F = 85.8). The 31 dramatically altered years were found via characteristic year analyses, and extreme changes occurred most often under relatively warm conditions. The mean minimum temperature in the reconstruction shows a clear warming trend by the 11-year moving average of the reconstructive series since the 1950s (the temperature increase: 0.341°C/decade). The driving factors of the mean minimum temperature were influenced mainly by the interaction of solar activity and large-scale atmospheric–oceanic variability, especially the westerly circulations.

Outbreaks caused by environmental effects such as COVID-19, MERS, SARS, or Ebola cause problems such as fear, anxiety, loneliness, depression, and hopelessness for people with or without a high risk of illness. This study aims to determine the levels of hopelessness and anxiety experienced by nursing students during the COVID-19 outbreak. This descriptive and cross-sectional study was conducted with students of a state university. In the collection of the data, Descriptive Characteristics Form prepared by the researchers, the Generalized Anxiety Disorder Test (GAD-7), and the Beck Hopelessness Scale (BHS) were used. The mean GAD-7 score of the students participating in the study was 6.65 ± 5.03 and the mean BHS score was 6.11 ± 4.91. It was determined that the score of GAD-7 and BHS were a significant positive high relationship between them (p < 0.001). Anxiety and hopelessness levels were found to be statistically significantly higher for those whose sleep and eating patterns affected negatively due to the pandemic, those who feared the pandemic and its economic effects, and those who did not want to work in the hospital during the pandemic period. There was a relationship between anxiety and hopelessness levels of nursing students participating in the study.

Abstract Background and Aims Anemia is one of the most important complications in chronic renal disease and inadequate erythropoietin production is the most important reason for anemia. Fibrosis of renal interstitium may be associated with inadequate synthesis of erythropoietin and anemia. In our study, we investigated the relationship between the severity of interstitial fibrosis (IF) in patients with primary glomerulonephritis (PGN) and anemia parameters. Method A total of 2794 patients who were recorded to the database of the Turkish Society of Nephrology, Glomerular Diseases (TSN-GOLD) Working Group between May 2009 and June 2019 were included in our national multicenter (44 centers) study. Patients aged 16 years or more with documented biopsy were included in the study. Patients were divided into four groups according to IF severity. IF was not detected in the interstitial area, was defined as none, if fibrosis was present in less than 25% of the area, defined as mild, if fibrosis was present in 25-50%, defined as moderate and if more than 50%, defined as severe. Anemia was defined as hemoglobin &lt;12 g/dl in adult female patients and &lt;13 g/dl in adult male patients, according to Clinical Practice Guidelines for anemia of CKD published by The Kidney Disease: Improving Global Outcomes Foundation. The relationship between IF severity and anemia parameters at the time of biopsy was investigated. Results In the study, 57% of the patients were male and their mean age was 41.0 ± 14.3 years. The mean eGFR was 82.7 ± 36.9 ml / min / 1.73 m2 and the hemoglobin level was 13.1 ± 1.9 g/dl. General characteristics of patients with and without anemia are given in Table 1. While 41.1% of patients had no IF, 41.2% had mild, 14.1% had moderate and 3.5% had severe IF. When the patients were divided into four groups according to the severity of IF, the mean hemoglobin and hematocrit levels were significantly different between the groups (Figure 1). Anemia was present in 960 patients (34.4%) (Figure 2). Anemia rate was significantly higher in the patients with IF than patients without IF (36.8% vs 30.9%, p = 0.001). Anemia rate was %25.1 in patients with eGFH≥60 ml/min/1.73m2 and 56% in patients with eGFR&lt;60 ml/min/1.73m2. Gender, serum albumin, eGFR, proteinuria, presence of diabetes, presence of nephrotic syndrome, and presence of IF were the independent variables in the regression analysis of hemoglobin-related factors (Table 2). Conclusion Approximately one-third of PGN patients had anemia at the time of biopsy and the frequency of anemia increases in patients with IF. The presence of IF is an independent risk factor associated with the development of anemia in PGN. The elucidation of the etiopathogenesis of anemia in PGN patients may play an important role in the follow-up and treatment of patients. Studies on IF can play a critical role.

SummaryIn a collaborative trial of eleven laboratories which was performed mainly within the framework of the European Community Bureau of Reference (BCR), a second reference material for thromboplastin, rabbit, plain, was calibrated against its predecessor RBT/79. This second reference material (coded CRM 149R) has a mean International Sensitivity Index (ISI) of 1.343 with a standard error of the mean of 0.035. The standard error of the ISI was determined by combination of the standard errors of the ISI of RBT/79 and the slope of the calibration line in this trial.The BCR reference material for thromboplastin, human, plain (coded BCT/099) was also included in this trial for assessment of the long-term stability of the relationship with RBT/79. The results indicated that this relationship has not changed over a period of 8 years. The interlaboratory variation of the slope of the relationship between CRM 149R and RBT/79 was significantly lower than the variation of the slope of the relationship between BCT/099 and RBT/79. In addition to the manual technique, a semi-automatic coagulometer according to Schnitger & Gross was used to determine prothrombin times with CRM 149R. The mean ISI of CRM 149R was not affected by replacement of the manual technique by this particular coagulometer.Two lyophilized plasmas were included in this trial. The mean slope of relationship between RBT/79 and CRM 149R based on the two lyophilized plasmas was the same as the corresponding slope based on fresh plasmas. Tlowever, the mean slope of relationship between RBT/79 and BCT/099 based on the two lyophilized plasmas was 4.9% higher than the mean slope based on fresh plasmas. Thus, the use of these lyophilized plasmas induced a small but significant bias in the slope of relationship between these thromboplastins of different species.

Purpose: i) To determine the relationship between the cardiac biomarkers ST2 and NT-proBNP with ejection fraction (EF) in heart failure (HF) patients. ii) Assess whether a superiority existed between the aforementioned cardiac markers in diagnosing the HF with reduced EF. iii) Determine the efficacy of both biomarkers in predicting a 30-day cardiovascular event and rehospitalization in patients with HF with reduced EF iv) To assess the influence of age, gender, BMI, anaemia and renal failure on the ST2 and NT-proBNP levels. Design and Methods: A prospective double-blind study was conducted to obtain data from a sample of 64 cardiology patients. A blood sample was collected to test for ST2 and NT-proBNP. An echocardiogram (to obtain EF value), electrocardiogram and questionnaire were also obtained. Results: Of the 64 patients enrolled, 59.4% of the population had an EF less than 40%. At the end of the 30- day period, 7 patients were warded, 37 were not warded, one died and 17 were non respondent. Both biomarkers were efficacious at diagnosing HF with a reduced EF. However, neither of them were efficacious in predicting 30-day rehospitalization. The mean NT-proBNP values being: not rehospitalized (2114.7486) and 30 day rehospitalization (1008.42860) and the mean ST2 values being: not rehospitalized (336.1975), and 30-day rehospitalization. (281.9657). Conclusion: Neither ST2 or NT-proBNP was efficacious in predicting the short- term prognosis in HF with reduced EF. Both however were successful at confirming the diagnosis of HF in HF patients with reduced EF.

AbstractThis study aimed to investigate the relationship between autofluorescence (AF) signal measured with ultra-wide field imaging and visual functions in patients with cone-rod dystrophy (CORD). A retrospective chart review was performed for CORD patients. We performed the visual field test and fundus autofluorescence (FAF) measurement and visualized retinal structures with optical coherence tomography (OCT) on the same day. Using binarised FAF images, we identified a low FAF area ratio (LFAR: low FAF/30°). Relationships between age and logMAR visual acuity (VA), central retinal thickness (CRT), central choroidal thickness (CCT), mean deviation (MD) value, and LFAR were investigated. Thirty-seven eyes of 21 CORD patients (8 men and 13 women) were enrolled. The mean patient age was 49.8 years. LogMAR VA and MD were 0.52 ± 0.47 and − 17.91 ± 10.59 dB, respectively. There was a significant relationship between logMAR VA and MD (p = 0.001). LogMAR VA significantly correlated with CRT (p = 0.006) but not with other parameters. Conversely, univariate analysis suggested a significant relationship between MD and LFAR (p = 0.001). In the multivariate analysis, LFAR was significantly associated with MD (p = 0.002). In conclusion, it is useful to measure the low FAF area in patients with CORD. The AF measurement reflects the visual field deterioration but not VA in CORD.

Abstract Background Substance-Related Disorders are among the most common social problems caused by using legal and illegal substances. Therefore, this study aimed at determining the quality of life (QoL) and its related factors among women with substance use disorders referring to substance abuse treatment centers in Hamadan, west of Iran. Methods This cross-sectional study was carried out on 120 Iranian female substance users recruited through the census sampling method in 2018. Data collection tools consisted of demographic characteristics and QoL assessment (SF-36). Data were analyzed using SPSS-16 via one-way analysis of variance (ANOVA) and chi-square tests. Results The mean age of the participants was 33.2 ± 12.1 years and the mean score of their total QoL was 35.35 ± 13.5. The results of multiple linear regression analysis indicated that using methamphetamine (β =  − 6.62) was the predictor of QoL in women. Moreover, there was a significant association between QoL and age (p < 0.001), educational level (p = 0.011), and age at first use (p < 0.001). Conclusion According to the results, the participants’ QoL was found to be at an unsatisfactory level. So, it is essential to implement educational help-seeking behavior for treatment and effectiveness educational, as well as holding mental health intervention, school-based substance abuse prevention, and harm reduction programs of substance use. This is especially important in adolescents, young, low-educated, early drug use, and methamphetamine user women, as it may increase the QoL

Introduction: There is a paucity of data evaluating the impact of heart rate (HR) during Targeted Temperature Management (TTM) and neurologic outcomes. Current resuscitation guidelines do not specify a HR goal during TTM. We sought to determine the relationship between HR and neurologic outcomes in a single-center registry dataset. Methods: We retrospectively studied 432 consecutive patients who completed TTM (33°C) after cardiac arrest from 2008 to 2017. We evaluated the relationship between neurologic outcomes and HR during TTM. Pittsburgh Cerebral Performance Categories (CPC) at discharge were used to determine neurological recovery. Statistical analysis included chi square, Student’s t-test and Mann-Whitney U. A logistic regression model was created to evaluate the strength of contribution of selected variables on the outcome of interest. Results: Approximately 94,000 HR data points from 432 patients were retrospectively analyzed; the mean HR was 82.17 bpm over the duration of TTM. Favorable neurological outcomes were seen in 160 (37%) patients. The mean HR in the patients with a favorable outcome was lower than the mean HR of those with an unfavorable outcome (79.98 bpm vs 85.67 bpm p < 0.001). Patients with an average HR of 60-91 bpm were 2.4 times more likely to have a favorable neurological outcome compared to than HR’s < 60 or > 91 (odds ratio [OR] = 2.36, 95% confidence interval [CI] 1.61-3.46, p < 0.001). Specifically, mean HR’s in the 73-82 bpm range had the greatest rate of favorable outcomes (OR 3.56, 95% CI 1.95-6.50), p < 0.001. Administration of epinephrine, a history of diabetes mellitus and hypertension all were associated with worse neurological outcomes independent of HR. Conclusion: During TTM, mean HRs between 60-91 showed a positive association with favorable outcomes. It is unclear whether a specific HR should be targeted during TTM or if heart rates between 60-91 bpm might be a sign of less neurological damage.
