In this study, the gene expression of some cancer-related genes was measured to differentiate between two types of therapeutic media in which hepatocellular carcinoma (HuH7) were harvested. The first was a conditional medium in which umbilical cord mesenchymal stem cells were harvested then diluted by DMEM media (1: 1) and the second was Co-culture medium that mesenchymal stem cells and HuH7 cells (1:1) together were incubated for 3 days in a medium. The latter was called Co- culture medium. Comparison of the Results of gene expression of Surviving, PCNA, Beta-Catenin, Telomerase and VEGF by using real-time PCR in several four-four-time intervals (48-72-96 hrs.) showed that in conditioned media and co-culture media, hepatoma cell line (HuH7) expressed a significant down-regulation in Surviving (p< 0.001), PCNA (p<0.001), VEGF(p<0.001) and Beta- Catenin(p=0.022) but not significant in Telomerase (p= 0.617). In our study, the measure of gene expression at different time (ALT), Aspartate aminotransferase (AST), Albumin, Alkaline phosphate, gamma GT, alpha- fetoprotein when compared regarding time Results in a significant in Alpha-fetoprotein (p < 0.001), ALT (p < 0.001) and AST (p < 0.001) while the results of Albumin (p = 0.650), Alkaline phosphatase (p = 0.329) and Gamma GT (p = 0.844) were non-significant.
本研究测定了一些癌症相关基因的表达,以区分两种治疗肝细胞癌(HuH7)的培养基。第一种是条件培养基,即收获脐带间充质干细胞,然后用 DMEM 培养基(1:1)稀释;第二种是共培养培养基,即间充质干细胞和 HuH7 细胞(1:1)一起在培养基中培养 3 天。后者称为共培养基。利用实时 PCR 技术,比较了存活、PCNA、β-Catenin、端粒酶和血管内皮生长因子的基因表达在四个时间间隔(48-72-96 小时)内的结果。结果表明,在条件培养基和共培养培养基中,肝癌细胞株(HuH7)的存活(p< 0.001)、PCNA(p<0.001)、VEGF(p<0.001)和β-Catenin(p=0.022)均有明显的下调,但端粒酶(p= 0.617)下调不明显。)在我们的研究中,不同时间的基因表达量(ALT)、天门冬氨酸氨基转移酶(AST)、白蛋白、碱性磷酸酶、γ GT、甲胎蛋白在时间上的比较结果显示,甲胎蛋白(p < 0.001)、谷丙转氨酶(p < 0.001)和谷草转氨酶(p < 0.001),而白蛋白(p = 0.650)、碱性磷酸酶(p = 0.329)和γ GT(p = 0.844)的结果不显著。

Stem cells are undifferentiated cells that can divide and differentiate into various types of cells. This special ability makes stem cells a hopeful treatment for regenerating damaged tissue and restoring diminished or completely lost function. In this case study, we discuss a 19-year-old soccer player who presented with a Grade III MCL tear on the right knee. Treatment for a Grade III MCL tear is controversial being that both surgical and non-surgical approaches have been effective. However, due to the patient’s sports background, the patient came to our clinic seeking a faster recovery using a non-surgical treatment. After extensive medical examinations, the patient began a treatment based on adipose tissue-derived stem cells injection. Adipose tissue-derived stem cells were harvested and injected into the distal insertion of the superficial MCL and on the deep MCL origin. After 122 days the patient was able to practice full contact sports which is a significant decrease compared to a recent study that averaged surgical recovery time to 181 days. The recovery was supported by an MRI which demonstrated full regeneration of the previously damaged MCL. This case study demonstrates the potential stem cells have in both complementing and replacing surgical treatments for tissue repair. In addition, this case study demonstrates the efficacy of accelerating recovery of MCL tears using stem cells which inspires hope of using stem cells in similar pathologies. Therefore, more clinical trials should be conducted to further expand research on stem cell treatment in regenerative medicine.
干细胞是一种未分化的细胞,可以分裂和分化成各种类型的细胞。这种特殊能力使干细胞成为再生受损组织、恢复减弱或完全丧失的功能的一种有希望的治疗方法。在本案例研究中,我们将讨论一名19岁的足球运动员,他的右膝MCL三级撕裂。III 级 MCL 撕裂的治疗是有争议的,因为手术和非手术治疗方法都很有效。然而,由于患者的运动背景,他来到我们诊所寻求非手术治疗,以求更快康复。经过广泛的医疗检查后,患者开始接受脂肪组织源性干细胞注射治疗。我们采集了源自脂肪组织的干细胞,并将其注射到多发性韧带浅层的远端插入处和多发性韧带深层的起源处。122天后,患者可以进行全面接触性运动,与最近一项平均手术恢复时间为181天的研究相比,时间明显缩短。核磁共振成像显示,之前受损的MCL完全再生,为患者的康复提供了支持。该案例研究表明,干细胞在补充和替代手术治疗进行组织修复方面具有潜力。此外,本案例研究还证明了干细胞在加速MCL撕裂恢复方面的疗效,从而激发了在类似病症中使用干细胞的希望。因此,应开展更多临床试验,进一步扩大干细胞治疗在再生医学中的研究。

Hypercholesterolemia and atherosclerosis are still the main cause of mortality in Central Asia. Study of the molecular mechanisms of endothelial dysfunction with changes in the nitroergic system in experimental hypercholesterolemia. The experiments were carried out on 28 Chinchilla rabbits with an average weight of 2.5-3.0 kg. The action of drugs was studied in dynamics: the initial 3-month condition and after one month of drug administration. The results obtained were compared with those of the control and intact groups. The activity of the enzyme nitrate reductase in the blood serum on the 30th day of the introduction of exogenous cholesterol increases only 1.15 times, then on the 60th and 90th days of the introduction - 1.3 and 1.76 times. In the dynamics of hypercholesterolemia and atherosclerosis in the blood serum, there are noticeable disturbances in the NO-ergic system.

The article provides statistics on the volume of surgical interventions on the extrahepatic bile ducts, the number of iatrogenic cicatricial strictures after traditional and laparoscopic cholecystectomies. The authors also provide figures of complications and mortality after various reconstructive and reconstructive interventions for iatrogenic strictures of the extrahepatic bile ducts. The article highlights the causes of hepatic choledochus strictures. Particular attention is paid to the increase in these complications after laparoscopic cholecystectomy. The article describes the classification of the level of cicatricial stricture of hepaticoholedoch according to E.I. Halperin and N.F. Kuzovlev, which is most convenient for practical application. The results of various reconstructive and reconstructive operations with iatrogenic strictures of hepaticoholedoch are critically evaluated and the importance of new, modern minimally invasive methods is emphasized. It is also emphasized that, despite the introduction of high-tech minimally invasive methods of diagnosis and treatment in surgical hepatology, and the progress in reconstructive surgery of the biliary tract, only the evaluation of the long-term results of treatment in this category of patients can give an objective assessment of the correctness of the chosen direction.
文章提供了有关肝外胆管手术干预量、传统和腹腔镜胆囊切除术后先天性卡他性狭窄数量的统计数据。作者还提供了肝外胆管先天性狭窄各种重建和再造介入术后的并发症和死亡率数据。文章强调了肝胆管狭窄的原因。文章特别关注腹腔镜胆囊切除术后此类并发症的增加。文章介绍了根据E.I. Halperin和N.F. Kuzovlev对肝胆管卡压性狭窄程度的分类,这种分类最便于实际应用。对各种肝胆管先天性狭窄的整形和重建手术的结果进行了严格评估,并强调了新的现代微创方法的重要性。同时还强调,尽管肝脏外科引入了高科技微创诊断和治疗方法,胆道重建手术也取得了进展,但只有对这类患者的长期治疗效果进行评估,才能对所选方向的正确性做出客观评价。

Objectives. This article's objective was to assess the reciprocating single-file systems Reciproc Blue 25.08 and Pro design R 25.06's cyclic and torsion fatigue resistance. The systems Reciproc Blue R25 (RB #25.08 taper), Prodesign R (PDR #25.06 taper), and WaveOne Gold (WOG #25.07 taper) (n = 20) were utilized to make sixty reciprocating instruments. The period to breakdown in an artificial stainless-steel canal with a 60° angle of curvature and a 5-mm radius was measured during cyclic fatigue resistance testing (n = 10). The torque and angle of rotation at failure of new instruments (n = 10) were assessed during the torsional test (ISO 3630-1) in the area 3 mm from the tip. Scanning electron microscopy was also used to view each fragment's shattered surface (SEM). In addition, a supplementary examination was performed to measure the cross- sectional area of each instrument 3 and 5 mm from the tip. The data were analyzed using one-way ANOVA and Tukey’s test, and the level of significance was set at 5%. Cycle Fatigue Resistance scores for PDR 25.06 were much higher (P 0.05). Both WOG 25.07 and RB 25.08 showed less resistance to fatigue (P 0.05). Based on the torsional analysis, PDR 25.06 had weaker torsional strength (P 0.05). No changes were found with RB 25.08 and WOG 25.07 (P > 0.05). PDR 25.06 showed higher angular rotation values than RB 25.08 and WOG 25.07. (P 0.05). Greater angular rotation was seen in both WOG 25.07 and RB 25.08. (P 0.05). The cross-sectional area analysis revealed that PDR 25.06 had the smallest cross-sectional areas at 3 and 5 mm from the tip (P 0.05). In comparison to RB 25.08 and WOG 25.07, PDR 25.06 had the highest cyclic fatigue resistance and angular rotation until fracture. Additionally, torsional strength was higher in RB 25.08 and WOG 25.07 than PDR 25.06. Clinical applicability in endodontic practise, reciprocating instruments that have undergone thermal treatment are used to prepare the root canals of canals that are curved and constrained; as a result, these instruments must exhibit high flexibility and suitable torsional strength to reduce the risk of instrument deformation.
目标。本文的目的是评估往复式单锉系统Reciproc Blue 25.08和Pro design R 25.06的循环和扭转疲劳抗力。系统Reciproc Blue R25 (RB #25.08锥度),Prodesign R (PDR #25.06锥度)和WaveOne Gold (WOG #25.07锥度)(n = 20)被用来制作60个往复仪器。在循环疲劳抗力试验中,测量了弯曲角为60°、半径为5mm的人工不锈钢管的破裂时间(n = 10)。在距尖端3mm的区域进行扭转测试(ISO 3630-1)时,评估新仪器(n = 10)失效时的扭矩和旋转角度。扫描电子显微镜也被用来观察每个碎片的破碎表面(SEM)。此外,还进行了补充检查,以测量每个仪器距离尖端3和5毫米的横截面积。数据分析采用单因素方差分析和Tukey检验,显著性水平设为5%。PDR 25.06组的抗疲劳评分明显高于对照组(p0.05)。WOG 25.07和RB 25.08对疲劳的抵抗力较弱(P < 0.05)。扭转分析显示,PDR 25.06的扭转强度较弱(p0.05)。RB 25.08、WOG 25.07无明显变化(P > 0.05)。PDR 25.06的角旋转值高于RB 25.08和WOG 25.07。(P 0.05)。WOG 25.07和RB 25.08都有较大的角度旋转。(P 0.05)。截面积分析显示,PDR 25.06在距尖端3 mm和5 mm处截面积最小(P < 0.05)。与RB 25.08和WOG 25.07相比,PDR 25.06在断裂前具有最高的抗循环疲劳性和角旋转性。此外,RB 25.08和WOG 25.07的扭转强度高于PDR 25.06。在根管实践中的临床适用性,经过热处理的往复器械用于准备弯曲和受限的根管;因此,这些仪器必须具有高柔韧性和适当的扭转强度,以减少仪器变形的风险。

Introduction: Platelet concentrates have gained popularity in periodontal regenerative therapy because of its autologous nature. it promotes wound healing after surgical periodontal therapy. Aim: to study the platelet count and antimicrobial efficacy of various platelet concentrates, such as PRP, PRF and IPRF Methodology: An Observational Study was carried out at Department of Periodontology & Implantology at Babu Banarasi das College of Dental Sciences. Sample size was 45. Ten ml of blood was drawn from the patient out of which 3ml each of blood will be used for PRP, PRF and I-PRF preparation and remaining 1ml of blood was used for determining the platelet count. For I-PRF preparation, 3ml of blood wias used, d centrifuged at 700 rpm for 3 minutes. For PRF preparation, Agar plates will be inoculated with plaque sample of same patient and will be labelled and divided into 3 compartments. Wells was prepared in the inoculated agar plate and 0.1 ml of PRP, PRF and I-PRF will be placed in those wells. Inoculated blood agar plates was then incubated aerobically at 37℃ for 24 hours to 48 hours. Results: The platelet count of i-PRF was statistically significant when compared to control (P < 0.001). It was also significant when compared to PRP (P < 0.01) and PRF (P < 0.001). Mean zone of inhibition around i-PRF (P < 0.01) and PRF (P < 0.05) reached statistical significance. Although a distinct zone of inhibition was seen with PRP, it was not statistically significant (P > 0.05). Conclusion: In the present study, although a distinct zone of inhibition was obtained with all test samples, it was significant with only i-PRF and PRF.
摘要血小板浓缩物因其自体特性在牙周再生治疗中得到广泛应用。它能促进牙周外科治疗后的伤口愈合。目的:研究血小板浓缩物(PRP、PRF和IPRF)的血小板计数及抗菌效果。方法:在巴布巴纳拉西达斯口腔科学学院牙周病与种植科进行观察性研究。样本量为45。抽取患者血液10ml,其中各3ml用于PRP、PRF和I-PRF制备,剩余1ml用于血小板计数测定。制备I-PRF时,取血3ml, 700 rpm离心3分钟。制备PRF时,将同一患者的菌斑样本接种琼脂板,并将其标记并分为3个室。在接种的琼脂板上打孔,在孔中分别加入0.1 ml PRP、PRF和I-PRF。接种的血琼脂板在37℃下有氧孵育24 ~ 48小时。结果:i-PRF组血小板计数与对照组比较,差异有统计学意义(P < 0.001)。与PRP (P < 0.01)和PRF (P < 0.001)比较也有统计学意义。i-PRF周围的平均抑制区(P < 0.01)和PRF周围的平均抑制区(P < 0.05)均有统计学意义。PRP虽有明显的抑制区,但无统计学意义(P > 0.05)。结论:在本研究中,虽然所有的测试样品都有明显的抑制区,但只有i-PRF和PRF具有显著的抑制区。

Aim: to study the platelet count and antimicrobial efficacy of various platelet concentrates, such as PRP, PRF and IPRF Methodology: An Observational Study was carried out at Department of Periodontology & Implantology at Babu Banarasi das College of Dental Sciences. Sample size was 45. Ten ml of blood was drawn from the patient out of which 3ml each of blood will be used for PRP, PRF and I-PRF preparation and remaining 1ml of blood was used for determining the platelet count. For I-PRF preparation, 3ml of blood wias used, d centrifuged at 700 rpm for 3 minutes. For PRF preparation, Agar plates will be inoculated with plaque sample of same patient and will be labelled and divided into 3 compartments. Wells was prepared in the inoculated agar plate and 0.1 ml of PRP, PRF and I-PRF will be placed in those wells. Inoculated blood agar plates was then incubated aerobically at 37℃ for 24 hours to 48 hours. Results: The platelet count of i-PRF was statistically significant when compared to control (P < 0.001).

This study is an attempt to identify some Sudanese Sweet Sorghum (Ankolib) [Sorghum bicolor (L.) Moench.] accessions using two types of DNA-based markers: RAPD and SSR. Seven (Ankolib) accessions were assayed, namely: Black Ankolib, Black White Ankolib, Dark Red Ankolib, Red Yellow Ankolib, White Ankolib, White Black Ankolib and Bengaga. All of the accessions were uniquely identified and fingerprinted. The levels of polymorphism among the accessions as revealed by (22) RAPD primers and (16) SSR primer pairs were (58%) and (76%) respectively, indicating that SSRs markers were highly polymorphic. The scored data of the two markers were analyzed using the Dice Coefficient to assess genetic relationships among the (7) (Ankolib) accessions. The results of the statistical analysis revealed that the accession Bengaga was distantly related to the other (6) accessions which all showed a close genetic similarity among them. UPGMA cluster analysis generated a dendrogram for each marker alone and for the combined data of the two markers. It was observed that in all of the dendrogram the accession Bengaga was found in a unique cluster thus indicating its uniqueness, since it is the only accession that has seeds that produce flour besides its juicy sweet stem.
本研究试图鉴定一些苏丹甜高粱(Ankolib)[高粱双色(L.)]。Moench。使用两种基于dna的标记:RAPD和SSR。选取7种安科利布,分别为:黑色安科利布、黑色白色安科利布、暗红色安科利布、红色黄色安科利布、白色安科利布、白色黑色安科利布和Bengaga安科利布。所有的物品都有独一无二的识别和指纹。22条RAPD引物和16条SSR引物的多态性水平分别为58%和76%,表明SSR标记具有高度多态性。采用Dice系数对两个标记的得分数据进行分析,评价(7)个(Ankolib)种质间的遗传关系。统计分析结果表明,本加与其他6个品种亲缘关系较远,遗传相似性较近。UPGMA聚类分析为每个标记单独和两个标记的组合数据生成树形图。我们观察到,在所有的树状图中,Bengaga被发现在一个独特的簇中,这表明了它的独特性,因为它是唯一一种除了多汁的甜茎外还有种子生产面粉的植物。
