Objective: To evaluate emergency contraception (EC) knowledge and use as well as identify factors associated to correct EC knowledge among public schools students in Morelos, Mexico.
Material And Methods: Cross-sectional study conducted in 2003-2004 in a sample of 1,550 students (ages 14-24). Logistic regression was used to identify factors associated to EC correct knowledge.
Results: Among all, 40% were men and 60% women with an average age of 19 years. Sixty percent have heard about EC, nevertheless, only 45% have correct knowledge about it; 3% of sexually active students (43%) reported its use. Factors associated to EC correct knowledge are: being a woman (OR=1.66; CI 1,33, 2,06), being sexually active (OR=1.77; CI 1,43, 2,18), middle income (OR=1.87; CI 1,04, 3,37), living in a semi-urban zone (OR=1.34; CI 1,02, 1,77), drinking alcohol (OR=1.78; CI 1,42, 2,22).
Conclusions: In Morelos, adolescents' knowledge of EC is scarce. Specific messages regarding its correct use are necessary.

Spatial association network structure of agricultural carbon emission efficiency in Chinese cities and its driving factors.
Sci Rep

College of Economics and Management, Huazhong Agricultural University, Wuhan, 430070, Hubei, China.
In light of the Chinese government's dual carbon goals, achieving cleaner production activities has become a central focus, with regional environmental collaborative governance, including the management of agricultural carbon reduction, emerging as a mainstream approach. This study examines 268 prefecture-level cities in China, measuring the carbon emission efficiency of city agriculture from 2001 to 2022. By integrating social network analysis and a modified gravity model, the study reveals the characteristics of the spatial association network of city agricultural carbon emission efficiency in China.

Inoculation of Bothrops jararaca snake venom (BjV) induces thrombocytopenia in humans and various animal species. Although several BjV toxins acting on hemostasis have been well characterized in vitro, it is not known which one is responsible for inducing thrombocytopenia in vivo. In previous studies, we showed that BjV incubated with metalloproteinase or serine proteinase inhibitors and/or anti-botrocetin antibodies still induced thrombocytopenia in rats and mice.

The mungbean yellow mosaic India virus (MYMIV, Begomovirus vignaradiataindiaense) causes Yellow Mosaic Disease (YMD) in mungbean (Vigna radiata L.). The biochemical assays including total phenol content (TPC), total flavonoid content (TFC), ascorbic acid (AA), DPPH (2,2-diphenyl-1-picrylhydrazyl), and FRAP (Ferric Reducing Antioxidant Power) were used to study the mungbean plants defense response to MYMIV infection.

Objective: This study aimed to examine the levels of physical activity (PA), sleep, and mental health (MH), specifically depression, anxiety, and stress, among Chinese university students. It also aimed to analyze the influencing factors of MH, providing a theoretical foundation for developing intervention programs to improve college students' mental health.
Methods: A stratified, clustered, and phased sampling method was employed.
A systematic review of circulating IP-10/CXCL10 in patients with Plasmodium infections in relation to disease severity.

Interferon γ-induced protein 10 kDa (IP-10) or C-X-C motif chemokine 10 (CXCL10) is produced and secreted from specific leukocytes such as neutrophils, eosinophils, and monocytes, which play key roles in the immune response to Plasmodium infections. This systematic review aimed to collate and critically appraise the current evidence on IP-10 levels in malaria patients. It provided insights into its role in malaria pathogenesis and potential as a biomarker for Plasmodium infections and disease severity.
