Article Synopsis
  • The study aimed to assess how running multiple marathons impacts heart structure and function in amateur male runners compared to healthy controls.
  • Results indicated that amateur marathon runners had larger heart sizes and thicker heart walls, but exhibited lower regional heart muscle strain in certain areas compared to the control group.
  • The findings suggest that long-term intense exercise might lead to changes in heart structure, prompting further research to determine if these changes are beneficial or harmful.

Purpose: Numerous studies have implicated the involvement of structure and function of the hippocampus in physical exercise, and the larger hippocampal volume is one of the relevant benefits reported in exercise. It remains to be determined how the different subfields of hippocampus respond to physical exercise.

Methods: A 3D T1-weighted magnetic resonance imaging was acquired in 73 amateur marathon runners (AMR) and 52 healthy controls (HC) matched with age, sex, and education.

Gliomas are one of the most common types of primary brain tumors. Despite recent advances in the combination of surgery, radiotherapy, systemic therapy (chemotherapy, targeted therapy) and supportive therapy in the multimodal treatment of gliomas, the overall prognosis remains poor and the long‑term survival rate is low. Thus, it is crucial to develop a novel glioma management method.

The bacterial community composition in four land-use types was determined and the visualized bacterial network was constructed by 16S rDNA Illumina MiSeq high-throughput sequencing technology and a molecular ecological network method. The results show that Proteobacteria, Acidobacteria, Bacteroidetes, Chloroflexi, Actinobacteria, Planctomycetes, Verrucomicrobia, Cyanobacteria, Gemmatimonadetes, Firmicutes, Nitrospirae, and Chlorobi are the main bacteria in this area. The number of nodes of urban green land, paddy field, and dry field bacteria networks is higher, and that of natural forest land is lower.

Background: Gliomas are one of the most common types of primary brain tumors. It is usually evaluated by gadolinium(III)-based contrast agents by magnetic resonance imaging (MRI) in the clinic. Methotrexate (MTX), as a type of folate analog that inhibits the enzyme dihydrofolate reductase, is widely used as a chemotherapeutic agent to treat gliomas in the experiment.

Topsoil (0-20 cm) samples (=101) in 5 different land use types in Shenyang North New Area (SNNA), Shenyang, China were collected using the uniform grid layout method to investigate the spatial distribution characteristics, composition spectrum, and source analysis of 16 polycyclic aromatic hydrocarbons (PAHs) listed as priority pollutants by the Environmental Protection Agency of the United States. Results showed that the total concentration of the 16 PAHs (Σ) in soils of SNNA ranged from 123.7 μg·kg to 932.

Multifunctional nanomaterials with simple structure and good biosafety, integrating multimodal imaging and therapeutic functions, can facilitate the development of clinical cancer treatments. Here, a simple but powerful pure bismuth based nanoparticle (Gd-PEG-Bi NPs) was developed from pure Bi NPs and gadolinium-diethylenetriaminepentaacetic acid-bis-tetradecylamide, which not only shows high quality MRI/CT/PAI triple-modal imaging, but can also be a potent photothermal therapy agent under the guidance of the triple-modal imaging. The Gd-PEG-Bi NPs showed good stability and excellent biocompatibility.

The major challenge in current clinic contrast agents (CAs) and chemotherapy is the poor tumor selectivity and response. Based on the self-quench property of IR820 at high concentrations, and different contrast effect ability of Gd-DOTA between inner and outer of liposome, we developed "bomb-like" light-triggered CAs (LTCAs) for enhanced CT/MRI/FI multimodal imaging, which can improve the signal-to-noise ratio of tumor tissue specifically. IR820, Iohexol and Gd-chelates were firstly encapsulated into the thermal-sensitive nanocarrier with a high concentration.

Porphyrin derivatives have been widely applied in MR imaging and photodynamic cancer therapy. We here report a novel Gd/Pt bifunctionalized porphyrin derivative (Gd/Pt-P1) for MRI-guided chemo-photodynamic cancer therapy. Gd/Pt-P1 was prepared from tetra(4-pyridyl) porphyrin (P1) via step by step coordination to cisplatin and gadolinium (Gd(iii)).

Pot experiments were conducted to investigate the effects of EDTA on the Pb availability in rhizospheric soil and the Pb accumulation in Tagetes patula and Salvia spendens. The results showed that 7 days after applying EDTA (3.0 mmol x kg(-1)) into soil, the concentration of ammonium acetate (1 mol x L(-1)) -extracted Pb in rhizospheric soil increased significantly (P < 0.

Soil contaminated with heavy metals cadmium (Cd) and lead (Pb) is hard to be remediated. Phytoremediation may be a feasible method to remove toxic metals from soil, but there are few suitable plants which can hyperaccumulate metals. In this study, Cd and Pb accumulation by four plants including sunflower (Helianthus annuus L.
