Article Synopsis
- The study investigates how different plant species, specifically Bothriochloa ischcemum (fibrous roots) and Artemisia vestita (tap roots), influence soil detachment rates under overland flow conditions on the Loess Plateau.
- It was observed that as plant density increased, the soil detachment rates decreased significantly, with Bothriochloa ischcemum proving to be more effective in reducing soil erosion compared to Artemisia vestita.
- The research establishes a mathematical relationship where soil detachment rate can be estimated using overland flow velocity, soil bulk density, and root length density, indicating the complex interactions between vegetation, soil, and hydrological factors.
[Influence of landscape pattern on elevation effect of δO in surface water in Hani Terrace].

Article Synopsis
- * Results indicated that water in forest areas showed smaller average values and variation in δO isotopes compared to terrace areas, suggesting different influences of these landscapes.
- * The elevation impact on hydrogen and oxygen isotopes was notable, but it was influenced more by the landscape gradient rather than precipitation patterns, leading to enhanced δO differences between forest and terrace patches.
Article Synopsis
- The study investigated the effectiveness of the internal target volume (ITV) method in enhancing intensity-modulated radiotherapy (IMRT) and three-dimensional conformal radiotherapy (3DCRT) for cervical cancer patients, focusing on survival and toxicity outcomes.
- A total of 477 patients were analyzed, divided into groups based on their treatment method, with outcomes measured for overall and progression-free survival using various statistical tests, including the Kaplan-Meier method.
- Results indicated that patients treated with ITV + IMRT exhibited better overall survival and lower rates of severe hematological toxicity compared to other treatment groups, highlighting the ITV method's potential benefits in radiotherapy planning.
Plant root systems can greatly reduce soil loss, and their effects on soil erosion differ across species due to their varied root traits. The purpose of this study was to determine the effects of root morphology traits of herbaceous plants on the soil detachment process. Ten herbaceous plants (dominant species) in the Loess Plateau were selected, and 300 undisturbed soil samples (including living roots from the selected herbages) were scoured with flowing water to measure their soil detachment capacities under six levels of shear stress (4.

Therefore, we explored the role of CCL7 in mast cell activity and motility in vitro and investigated the requirement for CCL7 in a murine model of IgE-mediated allergic conjunctivitis. For mast cells treated with IgE and Ag, the presence of CCL7 synergistically enhanced degranulation and calcium influx.

Objective: To investigate the prevalence of Capillaria hepatica in rodents from Anning Prefecture, Yunnan, and observe the susceptibility of C. hepatica to SD rats and KM mice.
Methods: Rodents were trapped in a cultivated filed of Wenquan Town, Annning from March 2010 to March 2012.
Hemophagocytic syndrome is a rare disease that is often fatal, despite treatment. An immunocompetent patient was presented with fever, hepatosplenomegaly, cytopenias, hypertriglyceridemia, hypofibrinogenemia, and hyperferritinemia, which conformed to a hemophagocytic syndrome diagnosis. Despite broad antibiotic treatment, the patient's clinical condition rapidly deteriorated and he died within 8 days of admission.

Here PDDV (peptide-DNA dual vaccine), a widely used non-viral gene delivery system, was applied. The cocktail PDDV, based on four Th1-type epitope peptides identified from Schistosoma japonicum vaccine candidates and CpG ODN1826, could induce dominant Th1-type response in C57BL/6J mice (P<0.
