Background: Solanum nigrum L. has been used in traditional Chinese medicine because of its diuretic and antipyretic effects. The present research concerned effects of crude polysaccharides isolated from Solanum nigrum L. on erythrocyte membranes of tumor-bearing S180 and H22 in mice.
Materials And Methods: Fluorescence- labeled red blood cell membranes were used with DPH fluorescence spectrophotometry to examine erythrocyte membrane fluidity, and colorimetry to determine degree of erythrocyte surface membrane blocking. Extent of reaction by tumor-bearing mice with the enzyme erythrocyte membrane bubble shadow detection of red cell membrane variation in the degree of closure before and after administration.
Results: Solanum nigrum polysaccharide could significantly improve the S180 and H22 tumor-bearing mice erythrocyte membrane fluidity, compared with the control group, the difference was significant (p<0.01), SNL can significantly improve the red blood cell membrane and then S180 tumor-bearing mice sealing ability, compared with the negative control group, the difference was significant(p<0.05, p<0.01). H22 tumor-bearing mice can increase red cell membrane and then sealing ability, the difference was significant (p<0.05). Solanum nigrum polysaccharide degree of fluidity and blocking two transplanted tumors in mice restored the ability to raise the red cell membrane has a significant effect.
Conclusions: Solanum nigrum L.-type mice transplanted tumor can affect the red blood cell membrane fluidity and re-closed, through the red cell membrane of red blood cells to enhance the immune function of the possibility of erythrocyte immunity against tumor formation garland provide experimental basis.

Cadmium (Cd) contamination presents a serious challenges for sustainable agriculture. This study evaluated the combined impact of arbuscular mycorrhizal fungi (AMF) inoculation and intercropping with Solanum nigrum on soil microbial diversity, enzyme activity, and environmental factors in soybean cultivation under high Cd stress. The combined treatment effectively reduced bioavailable Cd in soil, with the acid-soluble Cd fraction at 19.

Unlabelled: Liv-52, an herbal formulation consisting of seven distinct plants and Mandur Bhasma, is recognized for its hepatoprotective, anti-inflammatory, and antioxidant properties. To investigate the pharmacological potential of each phytochemical from these plants, we conducted ADMET analysis, molecular docking, and molecular dynamic simulations to identify potent molecules capable of inhibiting the interaction between Alpha-fetoprotein (AFP) and Cysteine aspartyl protease 3 (Caspase-3/CASP3). In our study, we have used molecular docking of all the compounds against AFP and filtered them on the basis of ADME properties.

Article Synopsis
- Conventional chemotherapy struggles with drug resistance and side effects in colorectal cancer (CRC), prompting research into natural compounds like Ursolic acid (UA) and Solasodine (Sol) that show promise in anti-tumor activity.
- This study focused on the synergy between UA and Sol in fighting CRC by triggering cell death (apoptosis) and preventing the spread (metastasis) of cancer through specific cellular pathways.
- Results indicated that combining UA and Sol effectively reduced CRC cell viability and promoted cancer cell death by enhancing gene expression related to apoptosis and autophagy, while also inhibiting factors that facilitate cancer spread.

Article Synopsis
- The study explores the use of plant growth-promoting rhizobacteria (PGPR), specifically Klebsiella sp. AW2, for decontaminating cadmium (Cd)-polluted soil and water in an eco-friendly way.
- The isolated PGPR strain showed tolerance to high levels of cadmium and achieved a biosorption rate of 40.99% under optimal conditions, indicating effective uptake of Cd through a specific chemisorption mechanism.
- Additionally, pot experiments revealed that applying the PGPR significantly improved the growth of Solanum nigrum and enhanced the plant's ability to extract cadmium from the soil, showcasing its potential as a biocleaner for contaminated environments.
