Summary: Male infertility is closely associated with chromosomal abnormalities, including reciprocal chromosomal translocation (RCT). RCT can disrupt the structure and function of genes responsible for spermatogenesis, leading to male infertility. This study describes two male carriers of RCTs and investigates the relationship between RCT breakpoints and male infertility. The results suggest that physicians should consider the clinical phenotype and RCT breakpoints in genetic counseling, and further research is needed on a gene located in the chromosome region 22q13 related to male infertility.

Summary: In order to promote optimal land allocation, China initiated market-oriented reform of industrial land in 2007. This study focuses on state-owned enterprises as the core research object and examines land purchase opportunities and prices from the perspective of industrial enterprise land purchases. The findings indicate that the advantage of state-owned enterprises in purchasing high-quality land has diminished, and a more market-oriented land market has emerged. Additionally, the advantage of state-owned enterprises purchasing land at a low price has also weakened, reducing distortion in industrial land prices. These results demonstrate the effectiveness of China's market-oriented reform, as state-owned enterprises have integrated into a more open and efficient land allocation environment.

Summary: This paper examines the impact of the increase in public employment on the private sector in 156 Greek municipalities. The study finds that an additional job in the public sector generates almost 0.7 jobs in the non-tradable sector, but has no significant effects on the tradable sector. The research also shows that the recent decline in the number of public servants did not significantly affect the private sector.

Summary: The study found that the opening of high-speed rail has a positive impact on population flow and market integration between cities in China. High-speed rail can enhance employment agglomeration, improve industrial structure, and have different effects on regional employment. Income, housing price, capital, and labor are all affected by high-speed rail. Additionally, the employment effect of high-speed rail is more significant in peripheral and southern cities. However, the effective radiation distance of high-speed rail stations is limited, and the labor market should pay more attention to the impacts of new massive public transportation.

Summary: Climate change will reshape ecological dynamics, potentially affecting human reliance on natural resources. Temperature increases may impact both fish and fishers in the small-scale inland fisheries, leading to changes in fishing behavior among households. However, the effects of higher temperatures on fish catch are limited. Incorporating human behavioral responses to changing environmental conditions is crucial for understanding the impacts of climate change on rural livelihoods, food production, and food access.

Summary: This paper reports on a randomized experiment conducted among Malawian agricultural households to study nonclassical measurement error (NCME) in self-reported plot area, and farmers' responses to new information - the objective plot area measure - subsequently provided to them. The experiment shows that most farmers have significant NCME in their self-reported plot areas, and the provision of true plot area measures through GPS has important effects on their self-reported data. This has implications for survey data collection methods, econometric inference, and the design of information-based interventions, as well as potential implications for farm management practices, input allocation, agricultural productivity, and the design of effective interventions.

Summary: In many low- and middle-income countries, there is a lack of sustainable solutions for infectious diseases, food and water challenges, and poverty. In West Africa, agricultural development and fertilizer use contribute to the spread of schistosomiasis by promoting the growth of aquatic vegetation, which serves as a habitat for snails that transmit the disease. A cluster randomized controlled trial showed that removing invasive vegetation from water points reduced infection rates in schoolchildren and improved water access. The removed vegetation can be used as livestock feed or converted into compost for crop production, providing economic incentives and public health benefits.

Summary: Progress towards achieving United Nations Sustainable Development Goals relies heavily on interventions in food value chains, yet data limitations have hindered the production of cross-nationally comparable estimates of the magnitude of these chains. This study introduces a standardized method and data series to estimate the distribution of consumer food expenditures between value-added activities on farms and in the post-farmgate value chain, shedding light on the significance of the post-farmgate food value chain and its evolving shares in response to changing economic, demographic, and agricultural conditions in different regions.
