Association between acetabular coverage over femoral head and rate of joint space narrowing in non-arthritic hips.

Aims: This study was performed to investigate the association between the acetabular morphology and the joint space narrowing rate (JSNR) in the non-arthritic hip.

Methods: We retrospectively reviewed standing whole-leg radiographs of patients who underwent knee arthroplasty from February 2012 to March 2020 at our institute. Patients with a history of hip surgery, Kellgren-Lawrence grade ≥ II hip osteoarthritis, or rheumatoid arthritis were excluded.

Use of Biotin-Labeled Geranyl Pyrophosphate for Analysis of Ykt6 Geranylgeranylation.

Functionally derivatized analogs of prenyl lipids are valuable tools for the detection and analysis of prenylated proteins. Using a biotinylated analog of geranylgeranyl, we previously identified Ykt6 as a substrate for a novel protein prenyltransferase, termed geranylgeranyltransferase type III (GGTase-III). Ykt6 is an evolutionarily highly conserved SNARE protein that regulates multiple intracellular trafficking pathways, including intra-Golgi trafficking and autophagosome-lysosome fusion.

Results from a phase 1b study of telisotuzumab vedotin in combination with osimertinib in patients with c-Met protein-overexpressing, EGFR-mutated locally advanced/metastatic non-small cell lung cancer (NSCLC) after progression on prior osimertinib.

Background: Osimertinib is the standard first-line treatment for advanced epidermal growth factor receptor (EGFR)-mutated NSCLC. However, treatment resistance is inevitable and increased c-Met protein expression correlates with resistance. Telisotuzumab vedotin (Teliso-V) is an antibody-drug conjugate that targets c-Met protein overexpression.

Transfemoral Compared to Transapical Transcatheter Aortic Valve Implantation in Chronic Dialysis-Dependent Patients.

Patients with end-stage kidney disease (ESRD) represent a high-risk population in terms of both development of and death by cardiovascular diseases. Outcome data of ESRD patients with severe aortic valve stenosis (AS) treated by transcatheter aortic valve implantation (AVI) are scarce. We aim to compare the outcome of ESRD patients undergoing transfemoral (TF) or transapical (TA) AVI.

Effects of Antioxidant Amino Acids on Cancer Sarcopenia.

Cancer sarcopenia is highly prevalent in patients with advanced cancer, which is closely related to the disease prognosis. Overcoming cancer sarcopenia is important for cancer treatment. Cystine and theanine (CT), antioxidant amino acids, have been applied to the nutritional intervention of various diseases but their effects remain unclear on cancer sarcopenia.

Histopathologic Comparison Among Drug Eruptions Induced by Enfortumab Vedotin, Brentuximab Vedotin, and Taxanes.

Microtubule-stabilizing agents (enfortumab vedotin and brentuximab vedotin) and microtubule-disrupting agents (docetaxel and paclitaxel) are used as anticancer agents but can also induce drug eruptions. Recently, mitotic arrest figures have been reported in various non-neoplastic cells as the histopathologic side effect of these drug eruptions. Therefore, we performed a comparative analysis of drug eruptions associated with these microtubule-targeting agents.

Artificial intelligence-enhanced navigation for nerve recognition and surgical education in laparoscopic colorectal surgery.

Background: Devices that help educate young doctors and enable safe, minimally invasive surgery are needed. Eureka is a surgical artificial intelligence (AI) system that can intraoperatively highlight loose connective tissues (LCTs) in the dissected layers and nerves in the surgical field displayed on a monitor. In this study, we examined whether AI navigation (AIN) with Eureka can assist trainees in recognizing nerves during colorectal surgery.

Introduction: Treatment options for patients with epidermal growth factor receptor (EGFR)-mutated non-small cell lung cancer (NSCLC) with disease progression on/after osimertinib and platinum-based chemotherapy are limited.

Methods: CHRYSALIS-2 Cohort A evaluated amivantamab+lazertinib in patients with EGFR exon 19 deletion- or L858R-mutated NSCLC with disease progression on/after osimertinib and platinum-based chemotherapy. Primary endpoint was investigator-assessed objective response rate (ORR).

Identification of deposits from modern and ancient large tsunamis by means of environmental DNA.

We examined the potential of environmental DNA (eDNA) for identifying tsunami deposits in the geological record using lake-bottom sediments in the Tohoku region, Japan. The presence of eDNA from marine organisms in a lacustrine event deposit provides very strong evidence that the deposit was formed by an influx of water from the ocean. The diverse DNA assemblage in the deposit formed by the 2011 Tohoku-oki tsunami included DNA of marine origin indicating that eDNA has potential as an identifying proxy for tsunami deposits.

Effect of Oral Lactate Administration on Skeletal Muscle Mass in Mice Under Different Loading Conditions.

Background/aim: Lactate is a physiologically active substance secreted by skeletal muscle that has been suggested to stimulate muscle mass gain. However, the molecular mechanism for lactate-associated muscle hypertrophy remains unclear. The purpose of the present study was to investigate whether oral administration of lactate increases muscle mass under different loading conditions.

Distribution and clinicopathological characteristics of G-CSF expression in tumor cells and stromal cells in upper tract urothelial carcinoma.

Background: Urothelial carcinoma (UC) is a common type of malignant disease; however, the diagnostic and prognostic markers of upper urinary tract urothelial cancer (UTUC) remain poorly understood because of its rarity.

Methods: To clarify the clinicopathological significance of granulocyte-colony stimulating factor (G-CSF) in UTUC, we analyzed the expression and distribution of G-CSF in 112 upper tract urothelial carcinoma (UTUC) samples with immunohistochemistry.

Results: In normal urothelium, G-CSF expression was weak or absent, whereas high expression of G-CSF was observed in UTUC tissues, both in tumor cells (TCs) and stromal cells (SCs).

A simplified scoring system for predicting treatment response in limited-stage small-cell lung cancer (EAST score).
