Genotypic variation in the response of pepper to salinity

Using 102 pepper (Capsicum annuum) genotypes, a greenhouse experiment has been conducted to study genotypic variation in tolerance to 100 mM sodium chloride (NaCl) in nutrient solution. Based on the severity of leaf symptoms caused by the NaCl treatment there was a substantial genotypic variation in salt tolerance. From this screening experiment, six sensitive and six tolerant genotypes were chosen to study dry matter production and root and shoot concentrations of sodium (Na), potassium (K) and calcium (Ca) in a growth chamber experiment in a nutrient solution with and without 150 mM NaCl. The genotypes selected as sensitive were highly damaged and developed severe chlorosis and necrosis under NaCl treatment, while the genotypes selected as tolerant were slightly affected. On average, decreases in shoot dry matter production caused by NaCl were greater in the sensitive than the tolerant genotypes. Application of salt increased shoot Na concentration at greater amount in the sensitive than the tolerant genotypes. Of the tolerant genotypes, the genotype Cac (Capsicum annuum var. cerasiforme) and 1245 F1 had around 2.45% Na in shoot while the sensitive genotypes Kandil and Pazarcik contained, on average, 5.4% Na. All sensitive and tolerant genotypes exhibited more or less similar shoot concentrations of K and Ca. There was very significant and positive correlation between severity of leaf symptoms and shoot Na concentration, but no correlation could be found in the case of K or Ca concentrations with the severity of leaf symptoms. The results indicate existence of substantial genotypic variation in tolerance to NaCl stress in pepper. It seems very likely that exclusion of Na from roots into growth medium plays a critical role in expression of high Na tolerance in pepper

Multi-step planning with learned effects of partial action executions

In this paper, we propose a novel affordance model, which combines object, action, and effect information in the latent space of a predictive neural network architecture that is built on Conditional Neural Processes. Our model allows us to make predictions of intermediate effects expected to be obtained during action executions and make multi-step plans that include partial actions. We first compared the prediction capability of our model using an existing interaction data set and showed that it outperforms a recurrent neural network-based model in predicting the effects of lever-up actions. Next, we showed that our model can generate accurate effect predictions for other actions, such as push and grasp actions. Our system was shown to generate successful multi-step plans to bring objects to desired positions using the traditional A* search algorithm. Furthermore, we realized a continuous planning method and showed that the proposed system generated more accurate and effective plans with sequences of partial action executions compared to plans that only consider full action executions using both planning algorithms.Comment: 18 pages, 6 figures total, 3 tables, Submitted to Advanced Robotic

Mushroom poisoning: retrospective analysis of 294 cases

OBJECTIVE: The objective of this study was to present special clinical and laboratory features of 294 cases of mushroom poisoning. MATERIALS AND METHODS: In this retrospective study, 294 patients admitted to the Pediatric and Adult Emergency, Internal Medicine and ICU Departments of Cumhuriyet University Hospital were investigated. RESULTS: Of 294 patients between the ages of 3 and 72 (28.97 ± 19.32), 173 were female, 121 were male and 90 were under the age of 16 years. One hundred seventy-three patients (58.8%) had consumed the mushrooms in the early summer. The onset of mushroom toxicity symptoms was divided into early (within 6 h after ingestion) and delayed (6 h to 20 d). Two hundred eighty-eight patients (97.9%) and six (2.1%) patients had early and delayed toxicity symptoms, respectively. The onset of symptoms was within two hours for 101 patients (34.3%). The most common first-noticed symptoms were in the gastrointestinal system. The patients were discharged within one to ten days. Three patients suffering from poisoning caused by wild mushrooms died from fulminant hepatic failure. CONCLUSION: Education of the public about the consumption of mushrooms and education of health personnel working in health centers regarding early treatment and transfer to hospitals with appropriate facilities are important for decreasing the mortality

High genetic diversity and differentiation of the babesia ovis population in Turkey

Babesia ovis is a tick‐transmitted protozoan haemoparasite causing ovine babesiosis in sheep and goats leading to considerable economic loss in Turkey and neighbouring countries. There are no vaccines available, therapeutic drugs leave toxic residues in meat and milk, and tick vector control entails environmental risks. A panel of eight mini‐ and micro‐satellite marker loci was developed and applied to study genetic diversity and substructuring of B. ovis from western, central and eastern Turkey. A high genetic diversity (He = 0.799) was found for the sample of overall B. ovis population (n = 107) analyzed. Principle component analysis (PCoA) revealed the existence of three parasite subpopulations: (a) a small subpopulation of isolates from Aydin, western Turkey; (b) a second cluster predominantly generated by isolates from western Turkey; and (c) a third cluster predominantly formed by isolates from central and eastern Turkey. Two B. ovis isolates from Israel included in the analysis clustered with isolates from central and eastern Turkey. This finding strongly suggests substructuring of a major Turkish population into western versus central–eastern subpopulations, while the additional smaller B. ovis population found in Aydin could have been introduced, more recently, to Turkey. STRUCTURE analysis suggests a limited exchange of parasite strains between the western and the central–eastern regions and vice versa, possibly due to limited trading of sheep. Importantly, evidence for recombinant genotypes was obtained in regionally interchanged parasite isolates. Important climatic differences between the western and the central/eastern region, with average yearly temperatures of 21°C versus 15°C, correspond with the identified geographical substructuring. We hypothesize that the different climatic conditions may result in variation in the activity of subpopulations of Rhipicephalus spp. tick vectors, which, in turn, could selectively maintain and transmit different parasite populations. These findings may have important implications for vaccine development and the spread of drug resistance.Instituto de PatobiologíaFil: Mira, Anabela.

The comparison of high and standard definition computed tomography techniques regarding coronary artery imaging

Objective: The aim was to compare coronary high-definition CT (HDCT) with standard-definition CT (SDCT) angiography as to radiation dose, image quality and accuracy. Material and Methods: 28 patients with history of coronary artery disease scanned by HDCT (Discovery CT750 HD) and SDCT (Somatom Definition AS). The scan modes were both axial prospective ECG-triggered. The vessel diameters and vessel attenuation values of totally 280 measurements from 140 coronary arteries were analyzed by two experienced radiologists. All data was analyzed by intraclass correlation test. Image quality graded by motion and stair step artifacts (grade 1, poor, to grade 4, excellent), accuracy of vessel inner and outer diameters were compared between the two CT units using the independent samples t-test and Mann-Whitney U test. Results: The intraclass correlation coefficient (ICC) of measured vessel attenuation values in SDCT between the two radiologists was exceedingly good. The ICC was higher in HDCT. The radiation dose of HDCT was higher than that of SDCT. The mean tube current was 180 (mA) in HDCT and 147(mA) in SDCT with the same tube voltage (kVp). There was no significant difference between image quality. Conclusion: HDCT has a higher radiation dose but has much more atenuation and the spatial resolution which improve measurement accuracy for imaging coronary arteries

Sleep quality and obstructive sleep apnoea and triple screen test results in pregnancy

In this study, we aimed to examine the relationship between sleep quality, sleep apnoea and triple screen test results. This was an observational descriptive research study. The STOP questionnaire and the STOP-BANG questionnaire were performed to assess obstructive sleep apnoea risk and Pittsburgh Sleep Quality Index was used to evaluate sleep quality. The average Pittsburgh Sleep Quality Index score of the participants was 5.92 ± 3.26. According to the STOP test, 11.40% (87) of the pregnant women had a high risk of OSAS, and, according to the STOP-BANG test, 32 participants were under high risk of OSAS. An increased risk was detected in 1.30% of the participants in terms of Trisomy18 and in 1.60% in terms of neural tube defects. A direct and significant relationship was detected between Trisomy 21 risk and STOP-BANG score. This is the first study to show this relationship. Sufficient evidence needs to be collected on this issue. Testing in earlier weeks of pregnancy and in the conception period may allow more meaningful assessment of the relationship of OSAS with chromosomal abnormalities.IMPACT STATEMENT What is already known on this subject? There is a link between OSAS and epigenetic changes. Components of the triple screen test, levels of serum total β-hCG and unconjugated oestriol are increased in OSAS. What do the results of this study add? An increase in Trisomy 21 risk is correlated with increased OSAS risk. Alpha Fetoprotein levels were higher in the low OSAS risk group. What are the implications of these findings for clinical practice and/or further research? This is the first study to show this relationship. Sufficient evidence needs to be collected on this issue. Treatment of OSAS may be necessary during pregnancy

Treatment preferences of orthopedic surgeons for closed, isolated middle-third diaphyseal long bone fractures without neurovascular injury in children: A cross-sectional survey

Objective: This study aimed to assess the treatment trends and the factors influencing the treatment methods of Orthopaedic Surgeons in closed, isolated, middle-third diaphyseal long bone fractures without any neurovascular injury in children. Methods: This was a cross-sectional electronic survey of Turkish Orthopaedic Surgeons who were active members of the Turkish Society of Children's Orthopaedics (TSCO) and still managing the children's fractures in their daily clinical practice. An initial e-mail including the electronic survey followed by three reminder e-mails was sent to 110 members, and then reminder telephone calls were made. Results: The survey response rate was 66/110 (60%). In recent years, a definitive trend to surgical treatment was not seen 98%, 77%, 39%, and 88% of the responders in the closed humerus, forearm, femur, and tibia mid-shaft fractures, respectively. Neither the years of expertise nor the intensity of daily pediatric patients of the participants did not affect the treatment trend in any fracture scenarios. The patient's age was the most cited factor influencing the responders' decisions on whether conservative or surgical treatment would be performed in each fracture scenario. The most cited lowest age limits for surgical treatment inclosed mid-shaft fractures of the humerus, forearm, femur, and tibia, were the adolescent age group, 10-12 years, six years, and ten years, respectively. Conclusion: This is the first study assessing the daily clinical practice of members of TSCO in the management of closed, isolated, non-complicated middle-third diaphyseal long bone fractures in children just before the covid-19 pandemic started. A marked tendency toward surgical treatment is seen in femur mid-shaft fractures, followed by forearm mid-shaft fractures up to a certain level. The patient's age is the main determinant of the responders' decisions on the type of treatment in closed, isolated, non-complicated middle-third diaphyseal long bone fractures in children
