| 1 | Basal cell carcinoma stem cells exhibit osteogenic and chondrogenic differentiation potential显示文摘Specific cell subpopulations identified as cancer stem cells(CSCs)can be found in basal cell carcinoma(BCC).Generally,CSCs have a marked trans-differentiation potential that could potentially be used in differentiation therapies.However,there are no studies regarding BCC CSCs multipotency.The aim of the study was to analyze the characteristic of CSCs of BCC with emphasis on their differentiation potential upon specific induction.Specific staining and cell morphology were used for differentiation confirmation,along with the expression analysis of osteogenic(ALP,BSP,Runx2,OCN,BMP2),chondrogenic(COL1 and COL2A1),adipogenic(PPAR-γ)and neurogenic(Nestin and MAP2)markers.BCC CSCs differentiated into osteogenic and chondrogenic lineages,as judged by staining and high expression of specific markers(from 2-to 92-fold higher upon induction).Concomitantly with differentiation,the levels of cancer stem cell markers decreased in the cultures.Adipo-differentiation and neuro-differentiation were unsuccessful.In conclusion,BCC CSCs exhibit the capacity to trans-differentiate,a characteristic that may potentially be useful in the development of new strategies for the treatment of aggressive BCCs. | MAJA MILOSEVIC MILOS LAZAREVIC BOSKO TOLJIC MILAN PETROVIC MIROSLAV VUKADINOVIC ZORAN JEZDIC BOBAN ANICIC DRAGO JELOVAC SVETLANA JOVANOVIC JELENA MILASIN | 2021 | BIOCELL2021，45，6： | 0 |
| 2 | Treatment options in stage I seminoma显示文摘Seminomas are most commonly diagnosed in clinical stage I(CSI).After orchiectomy,approximately 15%of patients in this stage have subclinical metastases.Adjuvant radiotherapy(ART)delivered to the retroperitoneum and ipsilateral pelvic lymph nodes has been the mainstay of treatment for many years.Although highly efficient,with long-term cancer-specific survival(CSS)rates approaching almost 100%,ART is associated with considerable long-term consequences,particularly cardiovascular toxicity and increased risk of secondary malignancies(SMN).Therefore,active surveillance(AS)and adjuvant chemotherapy(ACT)were developed as alternative treatment options.While AS prevents patient overtreatment,it is associated with strict follow-up regimens and increased radiation exposure due to repeated imaging.Due to equivalent CSS rates to ART,and lower toxicity,one course of adjuvant carboplatin presents the cornerstone of chemotherapy for CSI patients.CSS is almost 100%for patients with CSI seminoma,regardless of the chosen treatment option.Therefore,a personalized approach in treatment selection is preferred.Currently,routine radiotherapy for CSI seminoma patients is no longer recommended.Instead,it should be reserved for patients who are unfit or unwilling for AS or ACT.Identification of prognostic factors for disease relapse allowed for the development of risk-adapted treatment strategy and stratification of patients in low-risk and high-risk groups.Although risk-adapted policy needs further validation,surveillance is currently recommended in low-risk patients,while ACT is reserved for patients with a higher risk of relapse. | UROS BUMBASIREVIC MARKO ZIVKOVIC MILOS PETROVIC VESNA CORIC NIKOLA LISICIC NEBOJSA BOJANIC | 2022 | Oncology Research2022，30，3： | 0 |
| 3 | Non-thermal atmospheric-pressure positive pulsating corona discharge in degradation of textile dye Reactive Blue 19 enhanced by Bi_(2)O_(3) catalyst显示文摘In this work,monoclinic Bi_(2)O_(3) was applied for the first time,to the best of our knowledge,as a catalyst in the process of dye degradation by a non-thermal atmospheric-pressure positive pulsating corona discharge.The research focused on the interaction of the plasma-generated species and the catalyst,as well as the role of the catalyst in the degradation process.Plasma decomposition of the anthraquinone reactive dye Reactive Blue 19(RB 19) was performed in a selfmade reactor system.Bi_(2)O_(3) was prepared by electrodeposition followed by thermal treatment,and characterized by x-ray diffraction,scanning electron microscopy and energy-dispersive xray techniques.It was observed that the catalyst promoted decomposition of plasma-generated H_(2)O_(2) into ·OH radicals,the principal dye-degrading reagent,which further attacked the dye molecules.The catalyst improved the decolorization rate by 2.5 times,the energy yield by 93.4%and total organic carbon removal by 7.1%.Excitation of the catalyst mostly occurred through strikes by plasma-generated reactive ions and radical species from the air,accelerated by the electric field,as well as by fast electrons with an energy of up to 15 eV generated by the streamers reaching the liquid surface.These strikes transferred the energy to the catalyst and created the electrons and holes,which further reacted with H_(2)O_(2) and water,producing ·OH radicals.This was indentified as the primary role of the catalyst in this process.Decolorization reactions followed pseudo first-order kinetics.Production of H_(2)O_(2) and the dye degradation rate increased with increase in the input voltage.The optimal catalyst dose was 500 mg·dm^(-3).The decolorization rate was a little lower in river water compared with that in deionized water due to the side reactions of ·OH radicals with organic matter and inorganic ions dissolved in the river water. | Milica PETROVIC Dragan RADIVOJEVIC Sasa RANCEV Nena VELINOV Milos KOSTIC Danijela BOJIC Aleksandar BOJIC | 2024 | Plasma Science and Technology2024，26，2： | 0 |
