Objective: To determine the effects of exercise on trunk performance and balance in patients with spinal cord injury (SCI).
Methods: We searched the databases MEDLINE, Cochrane Library, EMBASE, Physiotherapy Evidence Database, Web of Science, PsycINFO, and CINAHL from inception to June 2020. Our search targeted studies such as randomized or non-randomized controlled trials and randomized crossover trials that evaluated the effects of exercise on trunk performance and balance in patients with SCI.
This retrospective study developed an automated algorithm for 3D segmentation of adipose tissue and paravertebral muscle on chest CT using artificial intelligence (AI) and assessed its feasibility. The study included patients from the Boston Lung Cancer Study (2000-2011). For adipose tissue quantification, 77 patients were included, while 245 were used for muscle quantification.

The primary pathological event in sepsis is widespread programmed cell death, or cellular self-sacrifice, of innate and adaptive immune cells, leading to profound immunological suppression. This severe immune dysfunction hampers effective primary pathogen clearance, thereby increasing the risk of secondary opportunistic infections, latent viral reactivation, multiple organ dysfunction, and elevated mortality.

In this study, we developed Tat-Ram13, a 25-mer peptide that fuses the NOTCH1 intracellular domain fragment RAM13 with a cell-penetrating HIV-1 TAT, for the treatment of T-cell acute lymphoblastic leukemia with aberrant NOTCH1 mutation. Tat-Ram13 significantly downregulated NOTCH1-target genes in T-ALL cell lines.
View Article and Find Full Text PDFImidazole dipeptides (IDPs) are found in the skeletal muscles and brains of various animals, and they exhibit unique functions like antioxidant and antiaging properties. Despite their importance, the metabolic mechanisms and physiological roles of IDPs remain unclear. Herein, we propose a method for the simultaneous analysis of IDPs, their constituent amino acids, and taurine, which are difficult to separate using conventional labeling reagents or columns, using liquid chromatography-single quadrupole mass spectrometry with PBr column and our highly sensitive labeling reagent, 1-fluoro-2,4-dinitrophenyl-5-l-valine-,-dimethylethylenediamineamide (l-FDVDA).

Ferroelectric nematic liquid crystals (NFLCs) are promising electronic materials owing to their giant permittivity, polarization, and nonlinear optical coefficients. Although it is difficult to polymer-stabilize the NFLC orientation state due to their low affinity to polymers, in this study, we have succeeded in stabilizing the orientation into a blue phase (BP) three-dimensional structure by using BP polymer networks. This BP polymer-templated NFLC retains their ferroelectric properties and stabilizes with macroscopically canceled polarization due to the BP structure.

Background: Myocarditis is associated with an increased risk of conduction disturbances during the acute phase, which recovers in most cases but rarely recurs during the chronic phase.
Case Summary: A 50-year-old man who developed fulminant myocarditis after COVID-19 mRNA vaccination was discharged 24 days after admission. He was readmitted for heart failure associated with two P waves: one P wave (P1) had a normal amplitude and was dissociated from the QRS, and the other (P2) had a very low amplitude and was associated with the QRS.
In this study, thermosensitive liposomes (TSLs) encapsulating urinary excretable radiolabeled compounds were developed. We considered that the release of the radiolabeled compounds from the TSLs in the blood by heating the blood in peripheral tissues can achieve rapid clearance of radioactivity, resulting in improved imaging contrast. To demonstrate the hypothesis, classical TSLs mainly composed of 1,2-dipalmitoyl--glycero-3-phosphocholine with a phase transition temperature of 41 °C were used.

Objectives: This study aimed to determine whether the severity of preoperative gait disturbance remains after surgical resection in patients with intramedullary spinal cord tumors (IMSCTs), and to identify any factors influencing poor improvement in postoperative gait disturbance.
Methods: The study included a total of 128 patients with IMSCTs requiring surgical excision between 2006 and 2019.
The nuptial flight of ants usually occurs during certain periods of the year. Alate females and males fly out of their nests to mate simultaneously. In the genus Camponotus, sex-specific chemicals are deposited in the male head; however, their roles in nuptial flight have not yet been clarified.
View Article and Find Full Text PDFImmune checkpoint inhibitor (ICI)-induced adverse events due to excessive immune stimulation are problematic in immunotherapy. The activation of viral infection triggered by ICI-induced dysregulated immunity has been proposed; however, this association remains inconsistent. This study investigated the association between ICI administration and cytomegalovirus (CMV) infections, a pathogen linked to immune abnormalities and reactivation, using the Food and Drug Administration Adverse Event Reporting System.

This study established a new KO model of diabetes by disrupting the insulin receptor substrate-2 (Irs2) gene in the golden (Syrian) hamster. Homozygous KO animals were born alive but with delayed postnatal growth until adulthood.

Depending on the coating speed, regularly spaced stripes or continuous films were observed. In the former case, columns of the HBC derivatives align more along the stripes, which are perpendicular to the coating direction, whereas in the latter case, columns of the HBC derivatives in the film align more along the coating direction.

Objective: To evaluate the relationship between pelvic incidence (PI) and proximal junctional kyphosis (PJK) in patients with Lenke type 5 adolescent idiopathic scoliosis (AIS).
Summary Of Background Data: Although PJK is a common complication of sagittal malalignment after posterior correction and fusion surgery (PSF), few studies have assessed its risk factors.

Amino acids with various functions are abundant in living organisms and foods. Recent advances in analytical technology show that trace amounts of D-amino acids exist in living organisms and foods. In addition, studies show that these amino acids are involved in various physiological functions that differ from those of L-amino acids.
