Bone marrow metastasis of ovarian cancer: A two‑center retrospective study and literature review.

Bone marrow metastasis (BMM) causes pancytopenia and disseminated intravascular coagulation (DIC), resulting in rapid mortality. The incidence of this disease is likely underestimated, with confirmed BMM occurring at approximately twice the rates expected clinically. The present study describes two detailed cases and includes a literature review of BMM caused by ovarian cancer.

Cytological features of oncocytic pleomorphic adenoma of the salivary gland: Using the Milan classification system to report 3 patients.

Pleomorphic adenoma (PA) is the most common salivary gland tumour. Pre-operative fine-needle aspiration (FNA) is currently one of the most widely used cytological examination techniques for the diagnosis of salivary gland tumours. Because PA exhibits characteristic cytological features, cytological diagnosis is straightforward in most cases.

Safety study on switching from intravenous to fixed‑dose subcutaneous formulation of pertuzumab and trastuzumab.

To the best of our knowledge, there have been no reports from clinical settings regarding safety information on a fixed-dose combination of pertuzumab and trastuzumab for subcutaneous injection (PHESGO) when switched from the intravenous formulation of pertuzumab and trastuzumab in Japan. The lack of information on switching from the intravenous formulation to PHESGO in clinical settings may contribute to hesitation in making the switch. The present study analyzed the safety of 51 patients with breast or colorectal cancer treated with PHESGO.

Separation of 100 nm-sized nanoparticles using a poly-Lys-modified monolith column.

Nanoparticles (approximately 100 nm in diameter) composed of lipid layers containing drugs or biologically active substances are attracting increasing attention in various fields, including medicine, as well as for signal transduction between cells. However, the separation of such nanoparticles conventional HPLC is challenging, often resulting in the clogging and collapse of nanoparticles, as well as a low separation efficiency. Thus far, no HPLC column capable of efficiently separating two types of 100 nm-sized nanoparticles in a short time has been reported.

Proton Beam Therapy for a Rare Anaplastic Pleomorphic Xanthoastrocytoma: Case Report and Literature Review.

Anaplastic pleomorphic xanthoastrocytoma (PXA) is a rare, aggressive WHO grade III tumor that primarily affects children and young adults. Despite surgery being the primary treatment, achieving complete tumor removal is often difficult due to its infiltrative nature, necessitating additional therapies like proton beam therapy (PBT). PBT, known for its precision in targeting tumors while minimizing damage to surrounding healthy tissue, has shown promise in treating malignant gliomas.

Mycoplasma pneumonia, caused by Mycoplasma bovis (Mycoplasmopsis bovis; M. bovis), is linked with severe inflammatory reactions in the lungs and can be challenging to treat with antibiotics. Biofilms play a significant role in bacterial persistence and contribute to the development of chronic lesions.

Healthcare performance of leprosy management in peripheral health facilities of Dhanusa and Mahottari, Nepal.

Background: The global elimination of leprosy transmission by 2030 is a World Health Organization (WHO) target. Nepal's leprosy elimination program depends on early case diagnosis and the performance of health workers and facilities. The knowledge and skills of paramedical staff (Leprosy Focal Person, LFP) and case documentation and management by health facilities are therefore key to the performance of health care services.

Impact of discontinuation of cephazolin prophylaxis on the incidence of postoperative adverse events in cataract surgery.

Background: Cataract surgeries are increasing annually, making appropriate medical management essential. The routine use of systemic antimicrobial agents for preventing surgical site infections lacks strong evidence and may increase the risk of drug-resistant bacteria and adverse events. This study examined the impact of discontinuing cefazolin (CEZ) administration during the perioperative period of cataract surgery on the incidence of postoperative adverse events and medical costs.

Association between the atherogenic index of plasma and long-term risk of type 2 diabetes: a 12-year cohort study based on the Japanese population.

Background: Atherosclerotic dyslipidemia is associated with an increased risk of type 2 diabetes (T2D). Although previous studies have demonstrated an association between the atherogenic index of plasma (AIP) and insulin resistance, there remains a scarcity of large cohort studies investigating the association between AIP and the long-term risk of T2D in the general population. This study aims to investigate the potential association between AIP and the long-term risk of T2D in individuals with normal fasting plasma glucose levels.

Gene expression of psychiatric disorder-related kinesin superfamily proteins (Kifs) is potentiated in alternatively activated primary cultured microglia.

Objective: Reactivity of microglia, the resident cells of the brain, underlies innate immune mechanisms (e.g., injury repair), and disruption of microglial reactivity has been shown to facilitate psychiatric disorder dysfunctions.

Peripheral nerve regeneration using a bioresorbable silk fibroin-based artificial nerve conduit fabricated via a novel freeze-thaw process.

While silk fibroin (SF) obtained from silkworm cocoons is expected to become a next-generation natural polymer, a fabrication method for SF-based artificial nerve conduits (SFCs) has not yet been established. Here, we report a bioresorbable SFC, fabricated using a novel freeze-thaw process, which ensures biosafety by avoiding any harmful chemical additives. The SFC demonstrated favorable biocompatibility (high hydrophilicity and porosity with a water content of > 90%), structural stability (stiffness, toughness, and elasticity), and biodegradability, making it an ideal candidate for nerve regeneration.

Claudin-11 regulates immunological barrier formation and spermatogonial proliferation through stem cell factor.

Tight junctions (TJs) between adjacent Sertoli cells are believed to form immunological barriers that protect spermatogenic cells expressing autoantigens from autoimmune responses. However, there is no direct evidence that Sertoli cell TJs (SCTJs) do indeed form immunological barriers. Here, we analyzed male mice lacking claudin-11 (Cldn11), which encodes a SCTJ component, and found autoantibodies against antigens of spermatocytes/spermatids in their sera.

Alzheimer's disease may develop from changes in the immune system, cell cycle, and protein processing following alterations in ribosome function.

The prevalence of Alzheimer's disease (AD) is increasing as society ages. The details of AD pathogenesis have not been fully elucidated, and a comprehensive gene expression analysis of the process leading up to the onset of AD would be helpful for understanding the mechanism. We performed an RNA sequencing analysis on a cohort of 1227 Japanese blood samples, representing 424 AD patients, 543 individuals with mild cognitive impairment (MCI), and 260 cognitively normal (CN) individuals.

Sympathetic innervation induced by nerve growth factor promotes malignant transformation in gastric cancer.

Sympathetic nerves regulate nearly all human organs. Their peripheral nerves are present in tumor tissue. Activation of the sympathetic nervous system promotes malignant transformation in several cancers.

Coherent harmonic generation of magnons in spin textures.

Harmonic generation, a notable non-linear phenomenon, has promising applications in information processing. For spin-waves in ferromagnetic materials, great progress has been made in the generation higher harmonics, however probing the coherence of these higher harmonics is challenging. Here, using in-situ diamond sensors, we study the coherent harmonic generation of spin waves in a soft ferromagnet.

3D scanner's potential as a novel tool for lymphedema measurement in mouse hindlimb models.

Lymphedema is characterized by persistent swelling due to impaired lymphatic function and presents significant challenges in both research and clinical settings. Traditional contact-based measurement techniques such as paw thickness and circumferential measurements using calipers or silk thread are useful but limited by observer variability and measurement accuracy. Non-contact methods, including various imaging techniques, offer improvements but often at higher cost and complexity.

Self-rerouting sensor network for electronic skin resilient to severe damage.

We propose a network architecture for electronic skin with an extensive sensor array-crucial for enabling robots to perceive their environment and interact effectively with humans. Fault tolerance is essential for electronic skins on robot exteriors. Although self-healing electronic skins targeting minor damages are studied using material-based approaches, substantial damages such as severe cuts necessitate re-establishing communication pathways, traditionally performed with high-functionality microprocessor sensor nodes.
