Research on soil bacterial community assembly and function under different straw returning practices in arid and semi-arid agricultural ecosystems over multiple years.

Introduction: Straw return has gained attention for its potential to improve soil quality and crop yields, particularly in semi-arid regions like the Tumu Chuan Plain Irrigation Area. Soil bacteria play a crucial role in regulating soil biological processes, and understanding how straw return affects bacterial populations can guide better agricultural management practices.

Methods: We investigated the impact of continuous straw return on soil bacterial communities using 16S rRNA gene sequencing.

Effects of different straw return methods on soil properties and yield potential of maize.

Long-term continual straw return can enhance soil quality and increase crop yields by perpetually altering the soil environment. However, little is known about how different straw return methods affect soil physicochemical properties, enzymatic processes, and crop yields. The study aims to determine how different straw return practices improve soil structure, nutrients, enzyme activities, and maize yields.

[Short-term effect of different returning methods of maize straw on the temperature of black soil plough layer].

Clarifying the effect of different maize straw returning methods on soil temperature is crucial for optimizing the management of farmland straw and the efficient utilization of heat resources in the black soil region of Northeast China. To investigate the impacts of straw returning methods on soil temperature, we conducted a field experiment with four treatments during 2018 and 2020, including plough tillage with straw returning (PTSR), rotary tillage with straw returning (RTSR), no-tillage with straw returning (NTSR), and a control treatment of conventional ridge tillage without straw returning (CT). We measured soil temperature and water content at the 5 cm, 15 cm and 30 cm soil layer, and the straw coverage rate during the 3-year maize growth period.

Effects of long-term tillage practices on the stability of soil aggregates and organic carbon in black soil farmland.

We examined the effects of different tillage practices on plough layer soil structure and organic carbon stabilization in black soil farmland with a long-term positioning platform. The wet-sieving method and infrared spectroscopy method were used to investigate the impacts of conventional tillage (CT), no-tillage (NT), sub-soiling tillage (ST), and moldboard plowing tillage (MP) on soil aggregates distribution and organic carbon characteristics in 0-40 cm soil layers. Compared to CT, both NT and ST treatments significantly increased the proportion of large macroaggregates (>2 mm) in the topsoil layer (0-20 cm)and that of small macroaggregates (0.

Efficacy of a new oncolytic adenovirus armed with IL-13 against oral carcinoma models.

Purpose: The efficacy of traditional therapies for oral carcinoma (OC) is limited. Oncolytic adenovirus, a novel strategy of cancer therapy, shows potential use in OC treatment. However, its clinical application is limited by pre-existing neutralizing antibodies.

Purified Phlorizin from (Wall.) Decne by HSCCC, Compared with Whole Extract, Phlorizin and Non-Phlorizin Fragment Ameliorate Obesity, Insulin Resistance, and Improves Intestinal Barrier Function in High-Fat-Diet-Fed Mice.

Natural products generally contain complex and multiple bioactive compounds that are responsible for the effects on health through complicated synergistic and/or suppressive actions. As an important raw material of local ethnic minority tea, ethnomedicines and food supplements in southwestern areas of China, (Wall.) Decne (DID) mainly consists of phlorizin (PHZ), which is the main active component.

[Multiple primary sarcomatoid carcinoma of the jejunum with postoperative lung and brain metastases: a case report and literature review].

We report a rare case of a multiple sarcomatoid carcinoma of the jejunum with postoperative lung and brain metastases. The patient underwent jejunum segmental resection for intussusception and gastrointestinal bleeding. Multiple metastasis ofbrain and lung occurred 4 months after the operation, and the patient died for multiple organ failure 8 months after the surgery.

[Discussion on relevant theories of "Qi-Blood-Shen" and formula implication of Guan-Xin-Jing capsule].

In the field of traditional Chinese medicine（TCM）,the definition of "Shen" contains a broad concept and a narrow concept. Broad "Shen" is the dominator and administrator of human vital movement,while narrow "Shen" means spirit, consciousness, thinking and emotions of human. "Shen" originates from innate essence of parents, and survives on acquired essence of water and food as well as the nutrition of its metaplastic Qi-Blood-Body fluid.

14,15-EET Suppresses Neuronal Apoptosis in Ischemia-Reperfusion Through the Mitochondrial Pathway.

Neuronal apoptosis mediated by the mitochondrial apoptosis pathway is an important pathological process in cerebral ischemia-reperfusion injury. 14,15-EET, an intermediate metabolite of arachidonic acid, can promote cell survival during ischemia/reperfusion. However, whether the mitochondrial apoptotic pathway is involved this survival mechanism is not fully understood.

Combined morphine and limb remote ischemic perconditioning provides an enhanced protection against myocardial ischemia/reperfusion injury by antiapoptosis.

Background: Both morphine and limb remote ischemic perconditioning (RIPer) can protect against myocardial ischemia/reperfusion injury (IRI). This experiment was designed to assess whether combined morphine and limb RIPer could provide and enhanced protection against myocardial IRI in an in vivo rat model.

Methods: One hundred male Sprague-Dawley rats were randomly allocated to six groups: sham, ischemia/reperfusion (IR), ischemic preconditioning, RIPer, morphine (M), and combined morphine and remote ischemic perconditioning (M + RIPer).
