Patellar tendon rupture is a severe complication following total knee arthroplasty. We encountered a case of rheumatoid arthritis with an incomplete rupture of the patellar tendon post-total knee arthroplasty. An 84-year-old woman was diagnosed with an incomplete rupture of the right patellar tendon 3 months post-total knee arthroplasty of her right knee.

ADAMTS-13 activity measurement is essential for the diagnosis of TTP, but conventional standard assays are manual and time-consuming. Automated ADAMTS-13 activity assays have recently become available; however, their accuracy remains challenging.

However, the relationship between immune-related adverse events (irAEs) and the effectiveness of nivolumab plus ipilimumab-based therapy in a real-world clinical setting remains uncertain.
Patients And Methods: We performed a retrospective analysis of 28 patients with advanced or recurrent NSCLC who underwent treatment with nivolumab plus ipilimumab, with or without platinum-doublet chemotherapy, from February 2021 to January 2023.
Background: Although the loading dose (LD) of vancomycin (VCM) contributes to its efficacy, it may not be conducted adequately. Herein, the objective was to evaluate the effect of LD on patient prognosis using therapeutic drug monitoring by pharmacists and elucidate the impact of an antimicrobial stewardship program (ASP)-driven educational intervention on the LD implementation rate and patient prognosis.
Materials And Methods: First, a retrospective cohort study was conducted involving 121 adult patients administered with VCM and compared with 28-day mortality in LD and non-LD groups.
Introduction: No study has investigated scan parameters in head and neck dual layer dual-energy computed tomography (DL-DECT). This study aimed to select the appropriate scan parameters in head and neck imaging by evaluating the scan parameter effects on the accuracies of CT numbers and conduct iodine quantification in DL-DECT.
Methods: A multi-energy phantom was scanned using a dual layer CT (DLCT) scanner.
Malaysia is one of the top exporters of palm oil, and although currently facing fierce resistance towards palm oil imports in some parts of the globe, one of the ways to utilize this commodity is by increasing palm biodiesel content in local commercial diesel. However, due to the oxygen-rich nature of biodiesel, its utilization suffers from increased nitrogen oxides (NO) emission compared to conventional diesel. To mitigate this issue and improve diesel engine performance and emissions using biodiesel-diesel blends, this study attempted to investigate implementation of a real-time non-surfactant emulsion fuel supply system (RTES) which produces water-in-diesel emulsion as fuel without surfactants.

This study compares stoma-related complications between loop ileostomy and loop colostomy after rectal resection, including minor complications, and discusses the characteristics of diverting stoma types.
Methods: A retrospective review was conducted in patients who underwent diverting stoma construction after rectal resection.
Aim: In Japan, day hospitals are a method of rehabilitation for psychiatric disorders, especially for recovering social functioning. Currently, 60% of day hospital users have schizophrenia, the majority of whom are long-term users (for over 1 year). However, they show no progress in community participation.

This risk might be higher when performing multiple-level (m-) MEL. The purpose of this study is to clarify the incidence rate of POSEH following single-level (s-) and m-MEL by each interlaminar level and identify the risk factors for POSEH following m-MEL.

The affinity of Phos-tag for phosphate monoester dianions is more than 10,000 times greater than that for other anions present in living organisms, such as carboxylic acid anions. We have developed and applied useful techniques for phosphoproteomics based on Phos-tag.

Each system consists of a histidine kinase (HK) and its cognate response regulator (RR). The His- and Asp-bound phosphate groups are extremely unstable under acidic conditions easily to be hydrolyzed within a few hours.

A variety of cell-based and cell-free protein expression systems are available to achieve this. The expression system must be selected carefully, especially for target proteins that require post-translational modifications.

The correlation between ascending aortic calcification and BMD has never been reported. Therefore, the purpose of the current study is to confirm the hypothesis that ascending aortic calcification can be used as a predictive factor for low BMD and to find a radiographic sign to show it.

View Article and Find Full Text PDFWe describe a standard protocol for phosphate-affinity fluorescent gel staining that uses a fluorophore-labeled dizinc(II) complex of a derivative of the phosphate-binding tag molecule Phos-tag to detect His- and Asp-phosphorylated proteins separated by SDS-PAGE. The procedure permits the quantitative monitoring of phosphorylated histidine kinases (His-phosphoproteins) and their cognate phosphorylated response regulators (Asp-phosphoproteins) in bacterial two-component signaling transduction systems. The total time required for each gel staining operation is about 2 h at room temperature.

In recent years, the number of examinations and treatments using computed tomography fluoroscopy (CTF) has been increasing, and there is concern about an increase in the exposure radiation dose of the operator. Use of half scan CTF can be expected to reduce the exposure radiation dose, but there is no report. The purpose of this study was to evaluate the exposure radiation dose at the operator's position and image quality when using a half scan CTF.

The procedure is based on an antibody microarray technique used in conjunction with an enhanced chemiluminescence system, and it permits the simultaneous and highly sensitive detection of multiple phosphoproteins in a cell lysate. By using this procedure, we have demonstrated the quantitative detection of the entire phosphorylation status of a target protein involved in intracellular signaling.

Previously, if a single protein band was detected, it was impossible to determine whether mobility of the protein altered by Mn Phos-tag in Phos-tag SDS-PAGE gels because SDS-PAGE and Phos-tag SDS-PAGE were performed on different gels. Moreover, when multiple protein bands were detected, it was difficult to determine whether the band with the highest mobility was altered mobility by Mn Phos-tag.

Phosphorylation of SFKs is also an essential modification for regulating their enzymatic activities. In this study, we used Phos-tag SDS-PAGE to investigate N-myristoylation-dependent phosphorylation of SFKs and their non-N-myristoylated G2A mutants.
