Objectives: To comparatively investigate biological tissues that are clinical products currently used for implantation in urological reconstruction. Specifically, we examined biological materials in vivo and evidence regarding the tissue response observed. Biological tissues are widely used in urological surgeries to treat conditions such as pelvic organ prolapse and stress urinary incontinence.

Methods: Histologic data from 4 biological sling materials, that is, small intestinal submucosa (SIS), cadaveric fascia lata, cadaveric dermis, and porcine dermis, implanted within mice (n = 64) were evaluated at 2, 4, 8, and 12 weeks. Recovered tissue was assessed by several biocompatibility parameters such as capsule formation (collagen deposition), cellular number, cell morphology, and angiogenesis.

Results: Data provide a scientific depiction of the cellular response to these biomaterials through a 12-week evaluation. SIS had a significantly higher level of angiogenesis and cell infiltrate as compared with all other material tested. Collectively, the data suggest that SIS has improved biocompatibility over other tested materials.

Conclusions: This study compared SIS with other biological tissues in an animal model and was found to have superior biocompatibility as seen in humans. This may be helpful for clinicians while selecting a particular biological material. The study provides evidence of the varying stages of remodeling each implant, with hopes to better understand the material response in vivo.

The complexation of nucleic acids and collagen forms a platform biomaterial greater than the sum of its parts. This union of biomacromolecules merges the extracellular matrix functionality of collagen with the designable bioactivity of nucleic acids, enabling advances in regenerative medicine, tissue engineering, gene delivery, and targeted therapy. This review traces the historical foundations and critical applications of DNA-collagen complexes and highlights their capabilities, demonstrating them as biocompatible, bioactive, and tunable platform materials.

The underlying mechanisms of the association of bone health with depression - an experimental study.

Background: Depression constitutes a risk factor for osteoporosis, but underlying molecular and cellular mechanisms are not fully understood. MiRNAs influence gene expression and are carried by extracellular vesicles (EV), affecting cell-cell communication.

Aims: (1) Identify the difference in miRNA expression between depressed patients and healthy controls; (2) Analyze associations of these miRNAs with bone turnover markers; (3) Analyze target genes of differentially regulated miRNAs and predict associated pathways regarding depression and bone metabolism.

In order to identify the pathogen responsible for Hedera nepalensis leaf blight and investigate effective biocontrol strategies, samples were collected from 10 significantly infected areas at Southwest Forestry University; four to six infected leaves were gathered from each area, followed by the isolation and purification of strains from the infected plant leaves using tissue isolation and hyphae-purification techniques. We conducted an examination of the biological characteristics and compared the inhibitory effects of different concentrations of Phomopsis sp. (50%, 25%, 16.
