  1. Artikel ; Online: Application of Computed Tomography Angiography in Preoperative Diagnosis of Coarctation of Aorta and Evaluation of Aortic Dilatation in Infants.

    Abstract Objective: To evaluate the occurrence of aortic dilatation and its associated predictors with coarctation of the aorta (CoA) in infants using multi-slice computed tomography (MSCT).
    Methods: The clinical data of 47 infantile patients with CoA diagnosed by MSCT and 28 infantile patients with simple ventricular septal defect were analyzed retrospectively. Aortic diameters were measured at six different levels, and aortic sizes were compared by z score. The coarctation site-diaphragm ratio was used to describe the degree of narrowing. Relevant clinical data were collated and analyzed.
    Results: The dilation rate and z score of the ascending aorta in the severe CoA group were significantly higher than those in the mild CoA group (11 [52.38%] vs. 21 [80.77%], P=0.038 and 2.00 ± 0.48 vs. 2.36 ± 0.43, P=0.010). Pearson's correlation analysis found that the z score of the ascending aorta was negatively correlated with the coarctation site-diaphragm ratio value (r=-0.410, P=0.004). A logistic retrospective analysis found that an increased degree of coarctation was an independent predictor of aortic dilatation (adjusted odds ratio 0.002; 95% confidence interval 0.00-0.819; P=0.043). The z score of the ascending aorta in the severe CoA group was significantly higher than that in the ventricular septal defect group (P<0.05).
    Conclusion: Most infants with CoA can also have significant dilatation of the ascending aorta, and the degree of this dilatation is related to the degree of coarctation. Assessment of aortic diameter and related malformations by MSCT can predict the risk of aortic dilatation in infants with CoA.

    Abstract Objective: To evaluate the accuracy of transthoracic echocardiography (TTE) and cardiac computed tomography angiography (CTA) in detecting the size and location of ventricular septal defects (VSD) in infants.
    Methods: Data from 258 infants diagnosed with VSD between January 2020 and December 2022 were retrospectively analyzed. All infants underwent both TTE and cardiac CTA. The accuracy of these imaging modalities was assessed by comparing their findings with intraoperative observations of VSD size and location.
    Results: Intraoperatively, the average VSD size was 6.1 ± 2.5 mm. The defects were classified as committed VSD (Type 1) in 45 patients, noncommitted VSD (Type 2) in 198 patients, inlet VSD (Type 3) in 12 patients, and muscular VSD (Type 4) in 3 patients. Echocardiography estimated the average VSD size at 5.6 ± 2.7 mm, with 42 patients identified as Type 1, 203 as Type 2, 10 as Type 3, and 3 as Type 4. Cardiac CTA estimated the average size at 5.9 ± 3.2 mm, with 48 patients identified as Type 1, 196 as Type 2, 11 as Type 3, and 3 as Type 4. The accuracy rates of TTE and cardiac CTA in diagnosing VSD location were 98.1% and 98.8%, respectively. A survey of surgeons indicated that 80% believe both TTE and cardiac CTA are essential preoperative evaluations.
    Conclusions: TTE accurately diagnoses the size and location of VSD, while cardiac CTA serves as a valuable complementary method to TTE. Most surgeons advocate for the combined use of these examinations for preoperative assessment.

    Abstract Research on the layout optimization of permanent basic farmland is essential for protecting arable land and ensuring food security. To achieve rapid spatial layout optimization of permanent basic farmland based on cultivated land quantity, quality, and ecology, this study selected Luoding City Guangdong Province as the research area, constructing an optimization index system for a permanent basic farmland layout from five levels: cultivated land quantity, cultivated land quality, spatial form, spatial planning, and ecological environment. At the same time, this study used geographic information system technology as an analysis tool and a comprehensive index evaluation method to analyze the current situation and optimize the permanent basic farmland spatial layout in Luoding City. Results show that from the perspective of spatial distribution, the distribution pattern of permanent basic farmland in Luoding City before and after the adjustment is essentially the same, primarily indicating that the middle is dense and the surrounding is sparse, the east and the west are dense, and the north is sparse. After optimizing the layout, the total area of the permanent basic farmland was found to have only increased by 5.2 hm2, and the rationality of its spatial layout was also greatly improved. The permanent basic farmland in Luoding City was optimized and improved in terms of the amount of arable land, arable land quality, spatial form, ecological environment, and spatial planning. Therefore, this study draws the following conclusions: Evaluating the rationality of arable land plot layout plays a critical role in delineating permanent basic farmland. In the future, the transfer of permanent basic farmland can be carried out according to the layout rationality of the current arable land and basic farmland to effectively promote permanent basic farmland delimitation in Luoding City. Moreover, the rapid optimization method of permanent basic farmland layout in Luoding City based on cultivated land quantity, quality, and ecology also provides a reference value for the permanent basic farmland delimitation of other major grain production areas across the country.

    Abstract Owing to their superior agronomic performance, the hybrids of vegetable crops are currently applied extensively. However, effective hybrid production requires a laborious manual emasculation to ensure the purity of hybrid seeds in tomato because of the lack of an effective male sterility system. Here, we created two types of tomato nuclear male-sterile lines with different screening markers in a clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated protein 9 (Cas9) system. Co-knockouts of male sterile 10³⁵ (Ms10³⁵) and glutathione S-transferase (GSTAA) created a male-sterile line marked by a green hypocotyl. The Ms10³⁵ biallelic mutation was introduced into the woolly tomato background, resulting in the linkage of male sterility and a non-woolly phenotype. Two types of male-sterile lines were easily selected at the seedling stage by hypocotyl color or trichome density and further showed high seed purity during hybrid seed production. Our work established the procedure for a rapid transfer of the male-sterile phenotype to the parents of hybrids without extra-modification by the CRISPR/Cas9 system that can be practically applied to hybrid seed production in tomato. This method will be the basis and example for sterile parent creation of multiple crops for hybrid production with the CRISPR/Cas9 system.

    Abstract We illustrate the importance of disaggregating electricity generation when considering responses to environmental policies. We begin by reviewing various approaches to electric sector modelling in Computable General Equilibrium (CGE) models, and then clarify and expand upon the structure and calibration of the “technology bundle” approach. We also simulate the proposed U.S. Clean Power Plan and show how a disaggregate electricity sector can change results. Our simulations indicate that both the ability to switch between generation technologies and the manner of aggregation in electricity production are important for quantifying the economic costs of the plan. A model that does not consider the heterogeneity of generation technologies can possibly underestimate the size of the carbon price but overestimate the economic cost of mitigation.

    Abstract Agriculture is a sector vulnerable to climate change. The potential decline of crop yields from this vulnerability has important policy implications for food security in South Asia. In this study an integrated assessment modelling framework is proposed to link a global economic model with global climate models via an econometric model of crop productivity. It is then used to examine the impact of climate change on food security in individual South Asian countries by exploring the interaction between climate-induced productivity change and changes in food production and food prices. The results of our simulations suggest that unfavourable climate change can reduce food production significantly from the historical trend and create upward pressure on food prices. This, in turn, will have serious adverse impacts on food security in the South Asian region.
