Residual PSC detection follows ultra‑trace‑analysis principles. LOD supports qualitative assessment. Assays employ PSC‑specific markers and proper references, with adaptation to differentiated cell populations from diverse PSC sources.
This document specifies the technical elements for bacteria and fungi detection by PCR assay which enables rapid, broad-spectrum detection of bacteria and fungi with high sensitivity. Qualitative judgement is based on LOD. Key detection points include efficient nucleic acid extraction, broad-spectrum primer-probe design, high amplification efficiency and minimised background interference.
BACKGROUND: Urinary incontinence is highly prevalent among older women, affecting more than one-third of this population and significantly impairing quality of life, independence, and healthcare utilization. Older women often present with complex needs that may require broader rehabilitation strategies. METHODS: This systematic review evaluated randomized controlled trials of physical therapy interventions for urinary incontinence in older women. PubMed, Embase, and Scopus were searched to October 2025. Eligible studies included women ≥60 years and assessed interventions such as Pelvic floor muscle training (PFMT), bladder training, Yoga, Pilates, general resistance training, electrical stimulation, or multimodal programs. Methodological quality was appraised using the PEDro scale, and random-effects meta-analysis was performed where appropriate. RESULTS: Twenty studies involving 2002 women across 13 countries were included. Eleven trials were rated as good quality and nine as fair. Meta-analysis demonstrated that PFMT significantly reduced urinary incontinence severity compared with usual care (SMD = -1.27, 95% CI: -2.18 to -0.36, p = 0.006). Multimodal programs combining PFMT with mobility, strength, or fall-prevention training also showed significant benefits (SMD = -0.98, 95% CI: -1.60 to -0.36, p = 0.002). Comparative studies indicated that PFMT was similarly effective to Yoga and Pilates, while adjuncts such as general resistance training or tibial nerve stimulation provided additional improvements. CONCLUSION: Physical therapy interventions, particularly PFMT and multimodal programs, are effective in reducing urinary incontinence severity and improving functional outcomes among older women. These findings support prioritizing physical therapy as an important management strategy, with multimodal approaches offering added value for enhancing functional independence and fall prevention.
Agrobacterium transfers DNA into plant cells, leading to tumors, hairy roots (HR), and natural genetically modified organisms (nGMOs). Transferred DNAs (T-DNAs) from agrobacteria and T-DNA-derived cellular T-DNAs (cT-DNAs) from nGMOs vary considerably and may carry up to 15 different genes. Among these, opine synthase (ops) genes encode the synthesis of opines used as nutrients by the agrobacteria. Earlier studies predicted large numbers of naturally transformed plant species, but only few have been identified and studied so far. We therefore developed a general method to detect cT-DNAs in all publicly available whole genome sequences (WGS) and Sequence Read Archive (SRA) data from land plants. To avoid false positives, we only retained DNA sequences coding for T-DNA proteins. A total of 2614 nGMO species were identified, most are eudicots. However, cT-DNAs were also found in 82 mosses and 75 ferns, showing that Agrobacterium can also generate natural transformants among the early land plants. Analysis of 149 cT-DNA maps revealed different types of T-DNAs. Most notably, these included small T-DNAs (mini T-DNAs) with a single opine synthase gene. Mini T-DNAs are not expected to induce tumors or HRs. The predominance of mini cT-DNAs in mosses and ferns, and the presence of more complex cT-DNAs in spermatophytes, indicate that mini T-DNAs represent the earliest types of T-DNA. Our study also detected unusual T-DNA integration patterns, with multiple copies spread out over several hundreds of kilobases.
BACKGROUND: The immune system of patients undergoing major surgery usually has obvious immune responses during the perioperative period, and the patient's immune status would affect the patient's prognosis. In this study single-cell sequencing technology was used to investigate the effect of surgery/anesthesia on peripheral blood mononuclear cells (PBMCs) in depth during the perioperative period. METHODS: We performed an in-depth analysis of our previously published data, which included a total of 4 patients were recruited in this study. Their peripheral blood samples were collected pre operation, 0, 24, and 48 h post operation, and then PBMCs were extracted, followed by single cell sequencing. The results of sequencing were analyzed with R packages seurat and scSTAR. Finally, RT-PCR technology was used to verify the expression of key genes in monocyte. RESULTS: The ratio of CD4+ and CD8+ T cells and Tregs showed little change, and the function of CD4+ and CD8+ T cells recovered soon. The function of Treg had not been restored 48 h post operation. Non-classical monocyte was impressed after surgery and showed no recovery trend within 48 h. Similar to scRNA-seq, the expression levels of MDM2 and SESN1 in patients with tumor increased significantly after surgery. CONCLUSIONS: Surgery/anesthesia had little effect on CD4+ and CD8+ T cells, and continued to affect the functional changes of Treg. It had more impact on monocytes, which may cause them to promote tumor development to a certain extent.
