Objectives: Adipose-derived stem cells (ADSCs) are widely used in wound care because they release a variety of cytokines. However, the molecular mechanism of paracrine action remains unclear. It has been reported that basic fibroblast growth factor (bFGF) enhances the therapeutic potential of ADSCs.

Background And Objective: Malignant ascites (MA) is common in patients with advanced cancer, and about 60% of patients with MA experience distressing symptoms. In addition, MA has been identified as a poor prognostic factor, therefore, making the management of MA an important issue. We aimed to review literature describing MA provide a narrative synthesis of relevant studies.

Cancer cells and embryonic stem (ES) cells share several biological properties, suggesting that some genes expressed in ES cells may play an important role in cancer cell growth. In this study, we investigated the possible role of zinc finger protein 296 (ZFP296), a transcription factor expressed in ES cells, in cancer development. First, we found that overexpression of in NIH3T3 mouse fibroblasts induced two phenomena indicative of cell transformation: enhanced proliferation under low-serum conditions and anchorage-independent growth.

In this study, we focused on the fat ratio within psoas muscle (FRPM) and sought to clarify the impact of FRPM on overall survival (OS) in stage IV gastric cancer (GC) patients undergoing systemic chemotherapy ( = 79, median age = 69 years, 59 males). The median FRPM was 1.67 %.

Background/aim: To prospectively evaluate the efficacy and safety of the BNT162b2 vaccine in solid cancer patients undergoing systemic chemotherapy (n=63).

Patients And Methods: COVID-19 anti-spike protein antibody levels were measured before the first BNT162b2 vaccination, just before the second BNT162b2 vaccination, one month after the second BNT162b2 vaccination, and 3 months after the second BNT162b2 vaccination. Anti-spike protein antibody seropositivity was set at ≥0.

We sought to examine the relationship between the SARC-F score and the Controlling Nutritional Status (CONUT) score in patients with gastrointestinal diseases (GDs, = 735, median age = 71 years, and 188 advanced cancer cases). The SARC-F score ≥ 4 (highly suspicious of sarcopenia) was found in 93 cases (12.7%).

Osteoarthritis (OA) is one of the major joint diseases, and the synovial inflammation is involved in the pathogenesis and progression of OA. Glucosamine (GlcN) is widely used as a dietary supplement for OA, and is expected to exert the antiinflammatory action in OA. However, the detailed mechanism for the antiinflammatory action of GlcN remains poorly understood.

Purpose: We sought to gain a better understanding of the low-dose ionizing radiation (LDIR)-induced molecular changes in transformed pre-malignant cells in their microenvironment.

Materials And Methods: The cellular response to LDIR was compared and contrasted using immortalized human Epstein-Barr virus-infected B-cells (EBV-B) in mono-culture, co-culture with human bone marrow derived stromal cells (MSC), or under the LDIR-induced bystander effect. The resulting alterations in protein and gene expression (including microRNA, miRNA) were evaluated by isobaric tags for relative and absolute quantification (iTRAQ) proteomics assay, western blot, cDNA array and quantitative reverse transcription polymerase chain reaction (RT-PCR), respectively.

Article Synopsis
  • The study investigates the role of the circadian clock in mast cells and how it influences allergic reactions that vary throughout the day.
  • Researchers compared allergic reactions in mice with normal mast cells and those with a mutated clock gene, finding that the mutation disrupted the expected time-of-day variations in allergic responses.
  • The findings suggest that the mast cell's internal clock, influenced by the adrenal gland, is crucial for regulating these allergic reactions, highlighting a potential connection to the daily patterns seen in allergic diseases.

Chemoresistance is one of the main obstacles to successful cancer therapy and is frequently associated with multidrug resistance (MDR). One of the most studied mechanisms of MDR is the high expression of ATP-binding cassette (ABC) transporters. Here, we demonstrated that NP-1250, an ABCG2 inhibitor, induced apoptotic cell death in ABCG2-overexpressing multidrug-resistant MCF7/mitoxantrone-resistant (MX) human breast carcinoma cells via a caspase-independent pathway.

Introduction: To examine the immune-modulatory effects of probiotics during early infancy, Bifidobacterium breve M-16V (B. breve) was administered to rat pups during the newborn or weaning period, and the expression of inflammatory genes was investigated using a cDNA microarray and real-time PCR.

Results: After B.

Background: Birt-Hogg-Dubé syndrome (BHDS) is an inherited autosomal genodermatosis characterised by fibrofolliculomas of the skin, renal tumours and multiple lung cysts. Genetic studies have disclosed that the clinical picture as well as responsible germline FLCN mutations are diverse.

Objectives: BHDS may be caused by a germline deletion which cannot be detected by a conventional genetic approach.
