Incorporating Percutaneous Laser Ablation for Early Breast Cancer Treatment: A Systematic Review.

We conducted a systematic review to compile the findings of all published studies on the use of percutaneous laser ablation (PLA) in the treatment of early-stage breast cancer. We aimed to identify appropriate methodology as well as parameters for the selection of suitable patients to optimize outcomes with the use of PLA. Additionally, we aimed to analyze whether this method is a viable alternative to current surgical treatments employed.

Efficacy of pembrolizumab plus lenvatinib as first-line treatment for metastatic renal cell carcinoma with multiple brain metastases.

Introduction: Patients with metastatic renal cell carcinoma have a poor prognosis and its specific pathogenesis remains unelucidated.

Case Presentation: At 78 years of age, a Japanese male patient was diagnosed with metastatic renal cell carcinoma (cT3N2M1 stage) and multiple brain metastases that were responsive to stereotactic radiation therapy followed by systemic combination induction therapy of pembrolizumab plus lenvatinib. Adverse events, including grade 3 hypertension, grade 2 eruption, and elevated grade 2 fever, were controlled by a dose reduction or suspension of drugs.

Cell cycle-dependent regulation of CRISPR-Cas9 repetitive activation by anti-CRISPR and Cdt1 fusion in the CRISPRa system.

CRISPR-Cas9 is a widely used genome-editing tool. We previously developed a method with improved homology-directed repair efficiency and reduced off-target effects by utilizing a fusion protein of AcrIIA4, a Cas9 inhibitor, and Cdt1, which accumulates in the G1 phase and activates Cas9 only in the S/G2 phase. However, it is unknown whether Cas9 inhibition by AcrIIA4 + Cdt1 occurs repeatedly in the G1 phase as the cell cycle progresses.

Page kidney in a child with ureteropelvic junction obstruction of lower moiety in a partial duplex system.

Reports of hydronephrosis-induced hypertension in pediatric patients are rare. A 7-year-old girl with hypertension was referred to our hospital with left hydronephrosis caused by ureteropelvic junction obstruction of the lower moiety in a partial duplex system. Because the lower moiety was almost nonfunctional, a laparoscopic heminephrectomy was performed.
