1Toward point-of-care assessment of patient response:a portable tool for rapidly assessing cancer drug efficacy using multifrequency impedance cytometry and supervised machine learning显示文摘We present a novel method to rapidly assess drug efficacy in targeted cancer therapy,where antineoplastic agents are conjugated to antibodies targeting surface markers on tumor cells.We have fabricated and characterized a device capable of rapidly assessing tumor cell sensitivity to drugs using multifrequency impedance spectroscopy in combination with supervised machine learning for enhanced classification accuracy.Currently commercially available devices for the automated analysis of cell viability are based on staining,which fundamentally limits the subsequent characterization of these cells as well as downstream molecular analysis.Our approach requires as little as 20μL of volume and avoids staining allowing for further downstream molecular analysis.To the best of our knowledge,this manuscript presents the first comprehensive attempt to using high-dimensional data and supervised machine learning,particularly phase change spectra obtained from multi-frequency impedance cytometry as features for the support vector machine classifier,to assess viability of cells without staining or labelling.Karan Ahuja Gulam M.Rather Zhongtian Lin Jianye Sui Pengfei Xie Tuan Le Joseph R.Bertino Mehdi Javanmard 2019Microsystems & Nanoengineering2019,5,1:4
2Diuretic and antioxidant activities of the aqueous extract of leaves of Cassia occidentalis(Linn.) in rats显示文摘Objective: To assess the putative diuretic and antioxidant properties of Cassia occidentalis(C. occidentalis) leaves' aqueous extract. Methods: Adult rats were administered with C. occidentalis leaves aqueous extract acutely(24-h) and subchronically(7 d), at doses 80, 160, 240, 320, and 400 mg/kg(per os). Negative control group received only an equivalent volume of distilled water, while the two positive control groups received the diuretic drugs furosemide(20 mg/kg, i.p.) and hydrochlorothiazide(HCTZ, 20 mg/kg, i.p.). Urinary elimination of electrolytes in response to treatments was evaluated, together with changes in concentrations of creatinine, urea, aldosterone, glucose, and albumin in urine and plasma. Various urinary indicators of kidney function and plasmatic markers of oxidative stress were also assessed. Results: The acute administration of C. occidentalis increased the urinary excretion of 107.58% at the higher dose tested, compared to negative control. The reference drugs furosemide and HCTZ induced increases of 84.27 % and 48.05 %, respectively. Acutely, the extract induced Na+ and Cl- elimination, whereas subchronically an increase in K+ elimination was also observed. The extract also improved the kidney function indexes and oxidative stress markers. These effects were dose-dependent and comparable with positive control observations. Conclusions: Our i ndings strongly suggest that C. occidentalis aqueous extract has diuretic and antioxidant activities, and deserves further studies considering the potential for the treatment of hypertension.Théophile Dimo Fidèle Ntchapda Joseph Barama David Romain Kemeta Azambou Paul Faustin Seke Etet 2015Asian Pacific Journal of Tropical Medicine2015,8,9:2

4Current evidence on potential of adipose derived stem cells to enhance bone regeneration and future projection显示文摘Injuries to the postnatal skeleton are naturally repaired through successive stepsinvolving specific cell types in a process collectively termed “bone regeneration”.Although complex, bone regeneration occurs through a series of well-orchestratedstages wherein endogenous bone stem cells play a central role. In most situations,bone regeneration is successful;however, there are instances when it fails andcreates non-healing injuries or fracture nonunion requiring surgical or therapeuticinterventions. Transplantation of adult or mesenchymal stem cells (MSCs) definedby the International Society for Cell and Gene Therapy (ISCT) as CD105+-CD90+CD73+CD45-CD34-CD14orCD11b-CD79αorCD19-HLA-DR- is beinginvestigated as an attractive therapy for bone regeneration throughout the world.MSCs isolated from adipose tissue, adipose-derived stem cells (ADSCs), aregaining increasing attention since this is the most abundant source of adult stemcells and the isolation process for ADSCs is straightforward. Currently, there isnot a single Food and Drug Administration (FDA) approved ADSCs product forbone regeneration. Although the safety of ADSCs is established from their usagein numerous clinical trials, the bone-forming potential of ADSCs and MSCs, ingeneral, is highly controversial. Growing evidence suggests that the ISCT definedphenotype may not represent bona fide osteoprogenitors. Transplantation of bothADSCs and the CD105- sub-population of ADSCs has been reported to induce bone regeneration. Most notably, cells expressing other markers such as CD146,AlphaV, CD200, PDPN, CD164, CXCR4, and PDGFRα have been shown torepresent osteogenic sub-population within ADSCs. Amongst other strategies toimprove the bone-forming ability of ADSCs, modulation of VEGF, TGF-β1 andBMP signaling pathways of ADSCs has shown promising results. The U.S. FDAreveals that 73% of Investigational New Drug applications for stem cell-basedproducts rely on CD105 expression as the “positive” marker for adult stem cells.A concerted effort involving the scientific community, clinicians, industries, andregulatory bodies to redefine ADSCs using powerful selection markers andstrategies to modulate signaling pathways of ADSCs will speed up thetherapeutic use of ADSCs for bone regeneration.Quang Le Vedavathi Madhu Joseph M Hart Charles R Farber Eli R Zunder Abhijit S Dighe Quanjun Cui 2021World Journal of Stem Cells2021,13,9:2
