Thymic epithelial tumors (TETs) are rare neoplasms that include thymomas, thymic carcinomas (TCs), and thymic neuroendocrine neoplasms (TNENs). These three tumor categories differ in aggressiveness, the incidence of recurrence after resection, the pattern of recurrence, and survival outcomes. Owing to the tumor's rarity, randomized trials have not been performed in the initial treatment setting.

The present study aimed to investigate the role of a recombinant protein based on human collagen type I (RCPhC1) as a scaffold in maintaining the human tumor microenvironment within a patient-derived tumor xenograft (PDTX) model. RCPhC1, synthesized under animal component-free conditions, was explored for its potential to support the human-specific stroma associated with tumor growth. PDTX models were established using resected colorectal cancer liver metastasis specimens, and stromal cell populations from humans and mice were compared using three scaffolds: No scaffold (control), Matrigel and recombinant human collagen type I, across two passages.

Occult breast cancer in an older woman: A case report.

Exp Ther Med

February 2025

Department of Breast Surgery, China-Japan Union Hospital of Jilin University, Changchun, Jilin 130033, P.R. China.

Occult breast cancer (OBC) is a relatively rare clinical condition that can complicate differential diagnosis efforts and delay the administration of specific treatments. The individualized therapy of patients with OBC should be performed based on their clinical symptoms, imaging findings and pathological diagnosis. The present case study describes a 51-year-old woman with a painless left axillary tumor.

Periodontal disease is recognized as a chronic multifactorial inflammatory condition initiated by dysbiosis within subgingival plaque biofilms. Antimicrobial peptides exhibit a wide spectrum of antimicrobial action, and thus, provide one of the first lines of host defense against oral pathogens. Aged garlic extract (AGE) is effective for preventing the progression of periodontal disease.

Objective: Microvascular changes, such as crossing nailfold capillaries, could be crucial for linking maximum lifetime body mass index (BMI) and microvascular complications in patients with type 2 diabetes mellitus (T2DM). However, the relationship between maximum lifetime BMI and microvascular changes remains elusive. This study aimed to elucidate the relationship between maximum lifetime BMI and the percentage of crossing nailfold capillaries among patients with T2DM.

Background and aim Subthreshold depression is a potential risk factor for major depressive disorder. Although the neurobiological mechanism underlying major depressive disorder is well-established, the mechanism underlying subthreshold depression has not yet been fully elucidated. We investigated the characteristics of brain abnormalities in participants with subthreshold depression using near-infrared spectroscopy (NIRS) owing to its portability.

Background: Non-Japanese-speaking patients taking medical treatment in Japan face language barriers and lack of language assistance. Language barriers influence all processes from preventive services to treatment, and insufficient communication can affect patient outcomes. Illness perception, which is related to illness-coping behaviors and self-care behaviors, is an important factor for effective treatment, but no studies have investigated the relationship between communication skills and illness perception among non-Japanese-speaking patients.

Background: Recently, autologous cultured fibroblast and platelet-rich plasma (PRP) therapies have been attempted for skin rejuvenation. Unlike PRP, grafted fibroblasts not only produce connective tissue but also influence the surrounding environment through a paracrine effect. Fibroblast-derived cytokines interact with and are modulated by neighboring tissue-constituting cells.

In the present study, the rare true bug (Schaefer & Ashlock, 1970), (Hemiptera, Heteroptera, Pentatomomorpha, Pentatomoidea, Saileriolidae), which is endemic to Vietnam, is redescribed and transferred from the genus China & Slater, 1956 to the genus Hsiao, 1964 based on morphological characteristics. Adults and nymphs of this species congregate in groups of several individuals and suck sap from the abaxial side of the leaves of sp. (Lauraceae).

Male medaka continue to mate with females despite sperm depletion.

R Soc Open Sci

January 2025

Laboratory of Animal Sociology, Department of Biology, Graduate School of Science, Osaka City University, Osaka 558-8585, Japan.

In animals where males engage in multiple matings, sperm depletion can substantially reduce the reproductive success of both sexes. However, little is known about how successive matings affect sperm depletion, fertilization rates and mating behaviour. Here, we investigated this phenomenon under laboratory conditions.

Oxidation reactions are vital tools in synthetic organic chemistry. Oxidation of organic species such as alcohols, phenols, aldehydes and ketones provides synthetically valuable organic compounds, especially synthetic intermediates for several biologically active compounds. Some of these synthetic intermediates have shown their synthetic utility in the total synthesis of natural products.

Peribronchiolar metaplasia is an uncommon lesion characterized by fibrosis and bronchiolar epithelial cell proliferation along the peribronchiolar alveolar walls, primarily in response to bronchiolar and peribronchiolar injuries. Peribronchiolar metaplasia usually appears as ground glass nodules or sub-solid nodules on computed tomography. However, we present an exceptional case of peribronchiolar metaplasia that appeared as a solitary solid nodule on computed tomography.
