Background: Disruption of the blood-brain barrier (BBB) in high-grade brain tumors is characterized by contrast accumulation on diagnostic imaging. This window of opportunity study correlates contrast imaging features with the tumor distribution of BBB-permeable (levetiracetam) and -impermeable (cefazolin) drugs.
Methods: Patients with a clinical diagnosis of a high-grade brain tumor underwent MRI for surgical planning.

Accurate thermodynamic calculations for aluminum alkyls require proper treatment of low-frequency vibrations poorly described by the harmonic approximation (HA). Here, we present a systematic investigation of hindered rotation and out-of-plane bending in aluminum trichloride (ATC) and its methyl derivatives, employing advanced computational methods to perform anharmonic entropy corrections, such as torsional eigenvalue summation (TES), the extended two-dimensional torsion method (E2DT), the multi-structural approximation with torsional anharmonicity (MS-T), and Fourier grid Hamiltonian (FGH). Our results reveal distinct structure-dependent behaviors: monomers exhibit near-free methyl rotations where the HA overestimates entropy by 20-30 J K mol, while dimers show more hindered rotations adequately described by the HA around room temperature.

Little is known about the biomarkers of mortality in SARS-CoV-2-infected patients without a previous diagnosis of diabetes. Thus, this study aimed to assess the fibrinogen-to-platelet ratio (FPR) and compare its predictive value with the main biomarkers for COVID-19 mortality, such as neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), leukocyte glucose index (LGI), and lactate dehydrogenase (LDH)/lymphocyte ratio. This retrospective cohort study in a population of Mexico included 70 non-diabetic patients with COVID-19 from 1 May 2020 to 30 September 2020.

Global phosphorus (P) resources are facing a depletion crisis, and pyrolysis of P-rich sewage sludge (SS) offers significant resource potential. Optimizing pyrolysis conditions remains key yet challenging for enhancing P retention and bioavailability. This study conducted a correlation-prediction-causation integrated framework (CPCIF) to investigate how heating temperature (HT), heating rate (HR), and retention time (RT) influence total P enrichment rate (BTPE), relative inorganic P transformation rate (BITP), and relative apatite P transformation rate (BAIP) from SS to biochar during pyrolysis.

Methods: This retrospective study included 213 ASD patients who underwent fusion from the lower thoracic spine (T9 or T10) to the pelvis. T10PA was measured on 6-week postoperative radiographs as the angle between the center of T10 and the hip center, and from the hip center to the midpoint of the S1 upper endplate.
