PLK1 overexpression suppresses homologous recombination and confers cellular sensitivity to PARP inhibition.

The overexpression of Polo-like kinase 1 (PLK1) is associated with poor clinical outcomes in various malignancies, making it an attractive target for anticancer therapies. Although recent studies suggest PLK1's involvement in homologous recombination (HR), the impact of its overexpression on HR remains unclear. In this study, we investigated the effect of PLK1 overexpression on HR using bioinformatics and experimental approaches.

SR-16234, a Unique Selective Estrogen Receptor Modulator, Suppressed Proliferation and Pain-Related Factor Expression by Inhibition of the Nuclear Factor-kappa B Pathway in Endometriotic Stromal Cells.

Problem: What is the effect of SR-16234 (SR), a selective estrogen receptor (ER) modulator, on human endometriotic stromal cells (ESCs)?

Method Of Study: Endometriotic tissues were obtained from 21 patients undergoing laparoscopic surgery for ovarian endometriomas (OEs). Normal eutopic endometrium during the luteal phase was obtained from 18 patients without endometriosis. ESCs isolated from OEs and normal eutopic endometrial stromal cells (NESCs) were cultured with SR and subsequently exposed to tumor necrosis factor (TNF)-α.

Two distinct enriched housings differentially ameliorate object and place recognition deficits in a rat model of schizophrenia.

Schizophrenia is a psychiatric disorder characterized by cognitive dysfunctions. These dysfunctions significantly impact the daily lives of schizophrenic patients, yet effective interventions remain scarce. In this study, we explored the effects of two enriched housing types-cognitive and physical-on cognitive dysfunctions in a rat model of schizophrenia.

Induction of acute silkworm hemolymph melanization by Staphylococcus aureus treated with peptidoglycan-degrading enzymes.

Staphylococcus aureus, a Gram-positive bacterium, causes inflammatory skin diseases, such as atopic dermatitis, and serious systemic diseases, such as sepsis. In the skin and nasal environment, peptidoglycan (PGN)-degrading enzymes, including lysozyme and lysostaphin, affects S. aureus PGN.

Characteristics of urinary tract infections in children with positive urine culture for Aerococcusurinae.

Urinary tract infections caused by Aerococcus urinae have rarely been reported in children, and the clinical characteristics remain unclear. We reviewed medical records of children whose urine cultures grew A. urinae (≥10 CFU/mL) at a tertiary children's hospital in Tokyo, Japan.

Acid-treated Staphylococcus aureus induces acute silkworm hemolymph melanization.

The skin microbiome maintains healthy human skin, and disruption of the microbiome balance leads to inflammatory skin diseases such as folliculitis and atopic dermatitis. Staphylococcus aureus and Cutibacterium acnes are pathogenic bacteria that simultaneously inhabit the skin and cause inflammatory diseases of the skin through the activation of innate immune responses. Silkworms are useful invertebrate animal models for evaluating innate immune responses.

Role of tenascin C in lesion formation in early peritoneal endometriosis.

Objective: To identify cytokines or extracellular matrix components that contribute to adhesion to, and invasion of, the peritoneum, proximal to lesions in the early phase of endometriosis.

Design: Laboratory-based study.

Setting: University Hospital and Laboratory of Animal Science.

A scoping review of remote facilitation during simulation-based healthcare education.

Background: Remote facilitation is a synchronous distance education method where instructors facilitate a lesson, in real-time, in physically separate conditions. In this scoping review, we aimed to describe types of remote facilitation used in a healthcare simulation, the influences on learner outcomes, and related factors.

Methods: We accessed PubMed, EMBASE, CINAHL, ERIC, and Web of Science using our search strategies.

Selection of highly responsive T cell receptors by an analysis combining the expression of multiple markers.

The clinical success of T cell receptor (TCR) gene-transduced T (TCR-T) cell therapy is expected as one of the next-generation immunotherapies for cancer, in which the selection of TCRs with high functional avidity (high-functional TCRs) is important. One widely used approach to select high-functional TCRs is a comparison of the EC50 values of TCRs, which involves laborious experiments. Therefore, the establishment of a simpler method to select high-functional TCRs is desired.

Risk factors indicating immune-related adverse events with combination chemotherapy with immune checkpoint inhibitors and platinum agents in patients with non-small cell lung cancer: a multicenter retrospective study.

Purpose: Immune checkpoint inhibitors (ICI) ushered in a new era for the treatment of non-small cell lung cancer (NSCLC). However, they carry the risk of immune-related adverse events (irAEs). Recently, various studies have been conducted on the predictive factors for irAEs, but there are no reports focusing only on ICI plus platinum agents.

Acute melanization of silkworm hemolymph by peptidoglycans of the human commensal bacterium Cutibacterium acnes.

Cutibacterium acnes is a pathogenic bacterium that cause inflammatory diseases of the skin and intervertebral discs. The immune activation induced by C. acnes requires multiple cellular responses in the host.

A Case of Post-cataract Surgery Endophthalmitis Successfully Treated with Conservative Therapy.

Background: Postoperative endophthalmitis after cataract surgery often requires emergency surgery if caused by an infection. However, early reoperation after the surgery put a heavy mental burden on the patient. Here we report a relatively mild case of postoperative endophthalmitis in which emergency surgery was avoided through careful observation including gram stain and culture test.

Frequency of Difficult Patient Encounters in a Japanese University Hospital and Community Hospitals: A Cross-sectional Study.

Objective Difficult patient encounters (DPEs) are defined as encounters with patients causing strong negative feelings in physicians. In primary care settings, DPEs account for approximately 15% of visits among outpatients. To our knowledge, this is the first epidemiological study of DPEs in Japan.

A controlled clinical trial comparing potent progestins, LNG-IUS and dienogest, for the treatment of women with adenomyosis.

Purpose: To evaluate the efficacy of two progestins, levonorgestrel intrauterine system (LNG-IUS) and dienogest (DNG), for adenomyosis.

Methods: This study enrolled 157 women with adenomyosis, randomized to either LNG-IUS ( = 76) or DNG ( = 81) groups as a controlled clinical trial for 72 months. Participants were classified by three different localizations of adenomyosis: diffuse, focal, and extrinsic.

Effect of Baffle Clearance on Scale Deposition in an Agitated Vessel.

The material deposition in a mixing tank agitated by the MAXBLEND impeller in a turbulent state was quantified and compared between cases with and without baffle clearance. Magnesium hydroxide formed from the chemical reaction between calcium hydroxide and magnesium chloride was used as a model of scale formation. Flow velocity in the tank was investigated by employing computational fluid dynamics simulation and experimentally validated by an ultrasonic velocity profiler method.

Physical findings and tests useful for differentiating lymphedema.

Stemmer's sign is useful in diagnosing lymphedema as it is present in 92% of the cases. Indocyanine green (ICG) lymphography is also useful for diagnosing lymphedema, and it allows them to see all the anatomy of the lymphatic vessels, leaking pumping capacity, and dermal reflux. The diagnostic ability of ICG lymphography and its evaluation capability for disease severity is similar to lymphoscintigraphy which is the gold-standard examination for extremity lymphoedema but with less invasiveness and a lower cost.

Successful discontinuation of biological disease-modifying antirheumatic drugs in patients with rheumatoid arthritis in real-world settings.

Objectives: To analyze the proportion of successful biological disease-modifying antirheumatic drugs (bDMARDs) discontinuation and related factors in patients with rheumatoid arthritis (RA) in clinical settings.

Methods: Among 1775 RA patients who started bDMARDs between 2003 and 2012, 43 patients with DAS28-ESR <3.2 at the time of bDMARD discontinuation were extracted.

Efficacy of Tokishakuyakusan add-on therapy with low-dose oral contraceptive pills on endometriosis patients with dysmenorrhea.

Aim: Tokishakuyakusan (TSS) is representative of popular Kampo medicines for Japanese women to treat dysmenorrhea, irregular menstruation and menopause. Current hormonal treatments and low-dose oral contraceptives (OCs) used as a first-choice drug for primary symptoms, however, have a high incidence of adverse events without improving patients' satisfaction. We evaluated the efficacy of TSS as additional treatment on the quality of life (QOL) of patients taking OCs with reduced therapeutic satisfaction.
