Article Synopsis
- The study investigates how gestational weight gain (GWG) affects the timing of lactogenesis II (DOL II), which is when mammals start producing mature breast milk after giving birth.
- It analyzes data from 16 articles, encompassing over 248,000 women, finding that excessive GWG increases the risk of delayed lactogenesis II, especially in overweight, obese, and underweight women who gained too much weight.
- Additionally, women with excessive GWG are likely to stop exclusive breastfeeding within one month after giving birth, indicating a negative impact of high GWG on breastfeeding practices.
Article Synopsis
- Alternatives to neonicotinoids are essential for controlling cereal aphids, and two formulations of Beauveria bassiana strains (Bb and TBb) were tested against them in a winter wheat crop.
- In field trials, both fungal treatments significantly reduced aphid infestation and density compared to control, with TBb showing higher efficacy than Bb.
- Although imidacloprid had quicker effects, its efficacy varied more, suggesting that the fungal options are viable contenders for aphid management.

Article Synopsis
- A new carbon-based solid acid catalyst was developed by functionalizing it with p-toluenesulfonic acid and incorporating a non-noble CuCo catalyst for converting fructose into 2,5-dimethylfuran (2,5-DMF) in a single step.
- The process involves first transforming fructose into 5-hydroxymethylfurfural (5-HMF) through dehydration, then converting 5-HMF into 2,5-DMF using the metal catalyst.
- The reaction achieved a high yield of 71.1 mol % of 2,5-DMF, outperforming previous methods, and the catalyst can be reused up to five times without significant loss in efficiency.
In this work, a simple room-temperature phosphorescence (RTP) method was first proposed to detect adriamycin, by using a functional material of Mn doped ZnS quantum dots (Mn-ZnS QDs) composited with poly(diallyldimethylammonium chloride) (PDDA). After PDDA was associated to the Mn-ZnS QDs, the RTP intensity was significantly enhanced. As a result, Mn-ZnS QDs/PDDA nanoassemblies greatly improve the adriamycin detection ability of QDs and provide an important method for developing more effective and sensitive adriamycin detection sensor.

Background: Several lines of evidence suggest that slow coronary flow (SCF) phenomenon seems to be an early form of atherosclerosis and low-grade inflammation plays a role in the development of SCF. Interleukin-6 (IL-6) is a pleiotropic cytokine, functions as a mediator of inflammatory response, and has both pro-inflammatory and anti-inflammatory properties. The aim of the present study is to investigate the relationship between IL-6 -634C/G polymorphism and SCF in Han Chinese.
