Study of ECoG, local cerebral circulation, and brain pO2 in 39 patients in the acute period of severe craniocerebral injury, as well as morphohistochemical measurements around the focus of crushing (in experiments) showed that the transitional zone is a risk zone because the "enzymatic death" of the tissue of this zone occurring at the moment of the injury predetermines extension of the areas of necrosis later on. The most effective measure is the removal not only of the detritus but also of the transitional zone of the focus within the range of tissue that had hardly suffered any changes and the inclusion of vasoactive and dehydration agents in the therapeutic complex.

Transition zone-based prostate-specific antigen density for differentiating clinically significant prostate cancer in PI-RADS score 3 lesions.

Department of Radiology, The Yancheng School of Clinical Medicine of Nanjing Medical University, Yancheng Third People's Hospital, Yancheng, China.
We intended to investigate the potential of several transitional zone (TZ) volume-related variables for the detection of clinically significant prostate cancer (csPCa) among lesions scored as Prostate Imaging Reporting and Data System (PI-RADS) category 3. Between September 2018 and August 2023, patients who underwent mpMRI examination and scored as PI-RADS 3 were queried from our institution. The diagnostic performances of prostate-specific antigen density (PSAD), TZ-adjusted PSAD (TZPSAD), and TZ-ratio (TZ volume/whole gland prostate volume) were analyzed.

Hydrous aluminosilicates are important deep water-carriers in sediments subducting into the deep mantle. To date, it remains enigmatic how hydrous aluminosilicates withstand extremely high temperatures in the mantle transition zone. Here we systematically investigate the crystal structures and chemical compositions of typical hydrous aluminosilicates using single-crystal X-ray diffraction, electron probe microanalyzer, and nanoscale secondary ion mass spectrometry.

The incorporation of desert sand-mineral admixture improves the abrasion resistance of concrete. To prolong the service life of assembled concrete channels and mitigate the depletion of river sand resources, the effects of fly ash (FA), silica fume (SF), desert sand (DS), and basalt fiber (BF) on the mechanical properties and the abrasion resistance of concrete were examined, alongside an analysis of their microstructures to elucidate the underlying mechanisms of influence. The results indicated that the abrasion resistance strength of concrete mixed with 10% FA and 0.

In this paper, the early drying shrinkage coefficients of different hydraulic cement mortars are calibrated through laboratory experiments for moderate-heat Portland cement (MHPC) and low-heat Portland cement (LHPC). By developing an improved mesoscale modeling approach, a 3D highly detailed simulation of concrete was generated, which incorporates the phases of mortar, aggregates, and interfacial transition zone (ITZ). The simulation result is in good agreement with the concrete early drying shrinkage experiment, exhibiting an error of less than 4.

Highly Hazardous Pesticides (HHPs) have been identified as substances with severe adverse effects, including carcinogenicity, endocrine disruption, and reproductive toxicity. The aim of this study was to evaluate pesticide residues in fruits and vegetables from Hopelchén to provide evidence for policy recommendations on pesticide regulation. A total of 25 samples were collected and analyzed using the QuEChERS method with GC-MS/MS and LC-MS techniques.
