| 1 | Anticancer potential of Alternanthera sessilis extract on HT-29 human colon cancer cells显示文摘Objective: To identify the bioactive extracts from Alternanthera sessilis and investigate its cytotoxicity potential against colon cancer cells, HT-29. Methods: This study examined the effects of three parts(aerial, leaf, stem) of whole plant on HT-29 colon cancer cell lines. Three different extracts from the plant parts were prepared by maceration technique using 80% ethanol. The anticancer activities were determined using MTT, clonogenic, cell motility and AOPI assay. The chemical composition profiling was analyzed by GC-MS. Results: Among three plant part extracts, leaf extract greatly suppressed the growth of colon cancer cells in time and dosage-dependent manner, followed by aerial and stem. The cytotoxicity results were rationalized with clonogenic, cell motility and AO/PI assay, where extract showed the most active activity compared to aerial and stem extracts. GC-MS analysis of leaf extract showed there were various recognized anti-cancer, anti-oxidant and anti-inflammatory compounds. Conclusions: Amid the screened extracts, the leaf extract exhibits the credible cytotoxic, anti-proliferative and apoptotic activity and hence, our findings call for additional research to conclude the active compounds and their mechanisms determining the apoptotic activity. | Sivapragasam Gothai Katyakyini Muniandy Norhaizan Mohd Esa Suresh Kumar Subbiah Palanisamy Arulselvan | 2018 | Asian Pacific Journal of Tropical Biomedicine2018，8，8： | 1 |
| 2 | Correlation of serum SARS-CoV-2 IgM and IgG serology and clinical outcomes in COVID-19 patients:Experience from a tertiary care centre显示文摘BACKGROUND The severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)virus has become a pandemic for the last 2 years.Inflammatory response to the virus leads to organ dysfunction and death.Predicting the severity of inflammatory response helps in managing critical patients using serology tests IgG and IgM.AIM To investigate the correlation of the serology(IgM and IgG)with reverse transcriptase polymerase chain reaction(RT-PCR)status,disease severity[mild to critical],intensive care unit(ICU)admission,septic shock,acute kidney injury,and in-hospital mortality.METHODS We conducted a longitudinal study to correlate serum SARS-CoV-2 immunoglobulin M(IgM)and immunoglobulin G(IgG)serology with clinical outcomes in coronavirus disease 2019(COVID-19)patients.We analyzed patient data from March to December 2020 for those who were admitted at All India Institute of Medical Sciences Rishikesh.Clinical and laboratory data of these patients were collected from the e-hospital portal and analyzed.A correlation was seen with clinical outcomes and was assessed using MS Excel 2010 and SPSS software.RESULTS Out of 494 patients,the mean age of patients was 48.95±16.40 years and there were more male patients in the study(66.0%).The patients were classified as mild-moderate 328(67.1%),severe 131(26.8%),and critical 30(6.1%).The mean duration from symptom onset to serology testing was 19.87±30.53 d.In-hospital mortality was observed in 25.1%of patients.The seropositivity rate(i.e.,either IgG or IgM>10 AU)was 50%.IgM levels(AU/mL)(W=33428.000,P≤0.001)and IgG levels(AU/mL)(W=39256.500,P≤0.001),with the median IgM/IgG levels(AU/mL),were highest in the RT-PCR-Positive group compared to RT-PCR-Negative clinical COVID-19.There was no significant difference between the two groups in terms of all other clinical outcomes(disease severity,septic shock,ICU admission,mechanical ventilation,and mortality).CONCLUSION The study showed that serology levels are high in RT-PCR positive group compared to clinical COVID-19.However,serology cannot be useful for the prediction of disease outcomes.The study also highlights the importance of doing serology at a particular time as antibody titers vary with the duration of the disease.In week intervals there was a significant correlation between clinical outcomes and serology on week 3. | Mohan Suresh Pratap Kumar Prasan Kumar Panda Vikram Jain Rohit Raina Sarama Saha Subbiah Vivekanandhan Balram Ji Omar | 2023 | World Journal of Biological Chemistry2023，14，2： | 0 |
| 3 | Amniotic membrane mesenchymal stromal cell-derived secretome in the treatment of acute ischemic stroke:A case report显示文摘BACKGROUND Stroke is the second and third leading cause of death and disability,respectively.To date,no definitive treatment can repair lost brain function.Recently,various preclinical studies have been reported on mesenchymal stromal cells(MSCs)and their derivatives and their potential as alternative therapies for stroke.CASE SUMMARY A 45-year-old female suffered an acute stroke,which led to paralysis in the left upper and lower limbs.The amniotic membrane MSC-derived secretome(MSCsecretome)was intravenously transplanted once a week for 4 wk.MSC-secretomeregulated regulatory T cells were investigated for the beneficial effects.The clinical improvement of this patient was accompanied by an increased frequency of regulatory T cells after transplantation.CONCLUSION Intravenous administration of MSC-secretome can potentially treat patients who suffer from acute ischemic stroke. | Fu-Hong Lin Yu-Xiao Yang Yu-Jun Wang Suresh Kumar Subbiah Xiao-Yun Wu | 2023 | World Journal of Clinical Cases2023，11，27： | 0 |
