Objective: This study aimed to compared the effects of different placement techniques to the sealing quality of mineral triokside aggregate (MTA) apical plugs at apexification technique by micro-computed tomography (micro-CT) and compared the bond strength to root dentin of an injectable MTA (BIOfactor MTA), MTA Angelus and AH Plus. Methods: Sixty dentinal root slices were obtained from 20 maxillary centrals.A canal-like hole was drilled into each slices canal space.The samples were divided into 3 groups (n=20).All materials were delivered into the holes. Push-out tests were performed and fracture types were analysed with a strereomicroscope. In the second part of the study,72 maxillary central teeth with standardised artificial divergent open apex were divided into 4 groups; MTA Angelus and BIOfactor MTA were mixed mechanically, and introduced to form 4 mm thick apical plugs by hand condensation or indirect-ultrasonic activation for 10 seconds. Incidence of external voids between dentin walls and MTA apical plugs and porosity inside MTA were determined by volumetric analysis with micro-CT. Results: No significantly difference was found between the bond strength values of the materials (p:0.370; p>0.05).The external voids and porous voids are similar in both MTA (p: 0.685; p>0.05).When indirect-ultrasonic activation was applied,there was significantly less porosity statistically than hand condensation (p:0.00; p<0.05). Conclusion: MTA Angelus and BIOfactor MTA materials showed similar results in terms of bond strength to root dentin, fracture types, adaptation to dentin walls and structural porosity rate. Both MTA materials showed less structural porosity when placed by indirect ultrasonic activation technique compared to manual condensation.
研究目的本研究旨在通过显微计算机断层扫描(micro-CT)技术,比较不同放置技术对三钾矿骨料(MTA)根尖塞封闭质量的影响,并比较可注射 MTA(BIOfactor MTA)、MTA Angelus 和 AH Plus 与根部牙本质的粘结强度。方法从 20 个上颌正中获取 60 个牙本质根切片,在每个切片的根管间隙钻一个管状孔,将样本分为 3 组(n=20)。进行推出试验,并用螺旋显微镜分析断裂类型。在研究的第二部分,72 颗具有标准化人工分歧开放顶点的上颌中牙被分为 4 组;MTA Angelus 和 BIOfactor MTA 以机械方式混合,并通过手动冷凝或间接超声激活 10 秒钟的方式导入以形成 4 毫米厚的顶端塞。牙本质壁和 MTA 根尖塞之间的外部空隙发生率以及 MTA 内部的孔隙率是通过显微 CT 的体积分析确定的。结果:两种材料的粘接强度值无明显差异(p:0.370; p>0.05),两种 MTA 的外部空隙和多孔空隙相似(p:0.685; p>0.05)。结论MTA Angelus 和 BIOfactor MTA 材料在与根部牙本质的粘结强度、断裂类型、对牙本质壁的适应性和结构孔隙率方面表现出相似的结果。与人工冷凝相比,两种 MTA 材料在使用间接超声活化技术时的结构孔隙率都较低。

Objective: The Activity Questionnaire for Adults and Adolescents (AQuAA) is used to evaluate physical activity (PA) levels in different age groups. Its validity and reliability in the Turkish language have not been studied yet. This study aims to adapt the AQuAA into Turkish and to investigate its validity and reliability.Methods: A total of 124 volunteers were included in the study. After the Turkish adaptation of AQuAA, the AQuAA-Tr version was administered to the volunteers for test-retest reliability twice, with an interval of two weeks, and the International Physical Activity Questionnaire Short Form (IPAQ-SF) for criterion validity. For construct validity, the step counts of the volunteers were followed for two weeks with the Samsung Health® smartphone pedometer application. The reliability of the AQuAA-Tr was evaluated with intra-class correlation coefficients (ICC). Spearman correlation coefficients (r) were used to analyze the relationships between continuous variables.Results: A total of 72 adolescents (51 females and 21 males, mean age 14.5 ± 0.1 years) and 52 young adults (32 females and 20 males, mean age 25.8 ± 1.3 years) participated in the test-retest reliability and criterion validity study. Thirty-four adolescents (26 female, 8 male, mean age 14.7 ± 0.2 years) and 39 young adults (27 female, 12 male, mean age 25.6 ± 1.5 years) were included in the construct validity study. The test-retest reliability of the questionnaire was in the range of strong to very strong (ICC = 0.704 to 0.982) in adolescents and moderate to strong (ICC = 0.606 to 0.851) in adults for different levels of PA. In the context of the criterion validity, although there were moderate to strong correlations (r = 0.413 to 0.768) between some PA levels of the IPAQ-SF and AQuAA-Tr in adolescents and moderate correlations (r = 0.422 to 0.525) in adults, the correlations were mostly weak or negligible. In relation to construct validity, although there were moderate correlations (r = 0.435 to 0.504) between the Samsung Health® data and some PA levels of the AQuAA-Tr in adults, the correlations were mostly weak or negligible. There were no correlations between the Samsung Health® data and AQuAA-Tr in adolescents.Conclusion: The reliability of the AQuAA-Tr was confirmed in both adolescents and adults. However, the criterion and construct validity of the AQuAA-Tr were not confirmed for either adolescents or adults. Introducing a PA questionnaire, which can provide detailed information about sedentary, light, moderate, and vigorous PA scores separately and total PA scores and allows the evaluation of PA in different categories, into our language is considered beneficial. Yet, the results of AQuAA-Tr should be interpreted carefully in the clinic.
目的:成人和青少年活动问卷(AQuAA)用于评估不同年龄组的体育活动(PA)水平。该问卷在土耳其语中的有效性和可靠性尚未得到研究。本研究旨在将 AQuAA 改编成土耳其语,并调查其有效性和可靠性:研究共纳入了 124 名志愿者。在将AQuAA改编成土耳其语后,对志愿者进行了两次AQuAA-Tr版本的重测信度测试,间隔时间为两周,并对国际体力活动问卷简表(IPAQ-SF)进行了标准效度测试。在构造效度方面,使用 Samsung Health® 智能手机计步器应用软件对志愿者的步数进行了为期两周的跟踪。AQuAA-Tr的可靠性通过类内相关系数(ICC)进行评估。斯皮尔曼相关系数(r)用于分析连续变量之间的关系:共有 72 名青少年(51 名女性和 21 名男性,平均年龄为(14.5 ± 0.1)岁)和 52 名青年(32 名女性和 20 名男性,平均年龄为(25.8 ± 1.3)岁)参加了重测信度和标准效度研究。34 名青少年(26 名女性,8 名男性,平均年龄为(14.7 ± 0.2)岁)和 39 名青壮年(27 名女性,12 名男性,平均年龄为(25.6 ± 1.5)岁)参加了构建效度研究。对于不同的活动量水平,青少年问卷的重测信度为较强至非常强(ICC = 0.704 至 0.982),成人问卷的重测信度为中等至较强(ICC = 0.606 至 0.851)。在标准效度方面,虽然在青少年中,IPAQ-SF 和 AQuAA-Tr 的某些 PA 水平之间存在中度至高度相关(r = 0.413 至 0.768),在成人中也存在中度相关(r = 0.422 至 0.525),但这些相关大多较弱或可以忽略不计。在构造效度方面,虽然三星健康®数据与成人 AQuAA-Tr 的某些 PA 水平之间存在中等程度的相关性(r = 0.435 至 0.504),但相关性大多较弱或可以忽略不计。青少年的 Samsung Health® 数据与 AQuAA-Tr 之间没有相关性:结论:AQuAA-Tr 的可靠性在青少年和成人中均得到了证实。结论:AQuAA-Tr 的可靠性在青少年和成人中均得到了证实,但其标准效度和结构效度在青少年和成人中均未得到证实。我们认为,在我们的语言中引入一份可以分别提供久坐、轻度、中度和剧烈运动得分以及总运动得分的详细信息,并允许对不同类别的运动进行评估的运动量调查问卷是有益的。然而,在临床中应谨慎解释 AQuAA-Tr 的结果。

Objective: The presence of an ethmomaxillary sinus (EMS) may increase the susceptibility to inflammatory paranasal sinus diseases such as chronic rhinosinusitis (CRS) and cause difficulties in surgical interventions to the paranasal sinuses. Therefore, this study aimed to examine the EMS in patients with and without CRS. Methods: The study included 150 patients (300 sides) diagnosed with CRS by the ear–nose–throat clinic and 151 individuals (302 sides) without CRS. Paranasal sinus computed tomography images were reviewed retrospectively. The presence of an EMS (bilateral or not) and its relationship with age and sex were examined. The severity of CRS was determined with the Lund–Mackay scoring system, and its relationship with EMS was evaluated. Results: The EMS was detected in 7 patients (7/301, 2.32%) and 9 sides (9/602, 1.49%) of 301 patients (602 sides) included. The incidence in the CRS group was 2.6%. Three cases were unilateral, and one was bilateral. The incidence in the control group was 1.98%, two cases were unilateral, and one was bilateral. According to the Lund–Mackay scoring system, the mean CRS severity was 8.62 (±5.47). Its severity was 5.25 (±3.94) in the EMS group and 8.71 (±5.48) in the non-EMS group. Conclusion: No statistically significant difference was found between the groups with and without CRS in terms of the presence of EMS (p = 0.723). No evidence reveals that EMS increased the severity of CRS.
目的:乙状颌窦(EMS)的存在可能会增加慢性鼻窦炎(CRS)等炎性副鼻窦疾病的易感性,并给副鼻窦的手术治疗带来困难。因此,本研究旨在对患有和未患有 CRS 的患者的 EMS 进行检查。研究方法研究对象包括 150 名经耳鼻喉诊所诊断为 CRS 的患者(300 人)和 151 名未患 CRS 的患者(302 人)。对鼻旁窦计算机断层扫描图像进行了回顾性审查。对是否存在 EMS(双侧或非双侧)及其与年龄和性别的关系进行了研究。采用 Lund-Mackay 评分系统确定 CRS 的严重程度,并评估其与 EMS 的关系。结果在纳入的 301 名患者(602 侧)中,7 名患者(7/301,2.32%)和 9 侧(9/602,1.49%)发现了 EMS。CRS组的发病率为2.6%。三例为单侧,一例为双侧。对照组的发病率为 1.98%,两例为单侧,一例为双侧。根据 Lund-Mackay 评分系统,CRS 的平均严重程度为 8.62(±5.47)。急救医疗组的严重程度为 5.25(±3.94),非急救医疗组为 8.71(±5.48)。结论就是否存在 EMS 而言,有 CRS 组和无 CRS 组之间没有统计学意义上的差异(p = 0.723)。没有证据显示 EMS 会增加 CRS 的严重程度。

Alternative Approach in Colorectal Anastomotic Stricture: Bougie Dilatation 大肠吻合口狭窄的替代方法:套管扩张术

Dear Editor, Anostomotic stricture (AS) is seen in 2-30% of patients after colorectal surgery. Various factors such as tissue ischaemia, anastomotic leakage and radiotherapy have been suggested in its pathogenesis [1,2]. Endoscopic methods (balloon dilatation, bougie dilatation, stents, endoscopic electroincision), digital dilatation, surgical methods (stapler stricturoplasty, transanal circular stapler resection, transabdominal redo-anastomosis) and corticosteroids are used in AS [3,4]. Surgery is generally preferred in complete/near complete AS [1]. Stents; the benefit of stents in AS after oncological surgery has not been shown [3]. However, Philip BC Pangg et al. treated near-total AS non-operatively with the colonic/rectal endoscopic ultrasound (EUS) anastomosis technique and a hot lumen metallic stent [5]. We applied 3-stage bougie dilation to the patient with near complete anastomotic stricture. A 59-year-old female patient who underwent laparoscopic anterior resection due to sigmoid colon tumor was followed up with complaints of abdominal swelling, intermittent abdominal pain and difficulty in defecation. One month later, when colonoscopy was performed, near complete anastomotic stricture was observed. Bougie dilatation was performed with maloney flexible bougie dilators under wire guidance. Bougie dilatation was performed 3 times with fifteen days intervals. After the first (33, 36 and 42 F) and the second bougie dilatation (36, 42 F), the upper segment of the anastomotic stricture was reached by gastroscopy. After dilatation with a bougie (42, 45 F) for the third time, the colonoscope was easily passed through the anastomosis line to the upper segment. Six months later, colonoscopy was performed and the proximal part of the anastomosis was easily passed without the use of bougie dilators. Balloon dilatation is the first method used in AS. However, several repetitions are necessary for the success of the procedure. In addition, the risk of perforation increases when the stricture diameter is <5 mm and length >1 cm. The chances of success in AS are lower compared to bougie dilatation. Endoscopic electroincision is recommended in failure of balloon dilatation. Digital dilatation: used in distal anorectal anostamotic strictures. Corticosteroid application: very large studies are not available. Bougie dilatation in AS provides tactile feedback, allowing the amount of resistance to the passage of the dilator to be estimated and perforation to be avoided. Bougie dilatation method is simple, inexpensive and low risk of complications. Especially Maloney flexible silicone bougie minimise the risk of complications. Bougie dilatators can remain intact for many years and can be reused. But balloon dilatators are not reused. Surgical methods are used in 3-4% (complete/near complete AS) in the failure of endoscopic methods. But mortality risk is high [1,4-6]. Therefore, the alternative method of Philip BC Pang et al. can be applied [5]. However, due t
亲爱的编辑,2-30%的结直肠手术后患者会出现吻合口狭窄(AS)。其发病机制有多种因素,如组织缺血、吻合口漏和放疗等[1,2]。强直性脊柱炎可采用内窥镜方法(球囊扩张术、球囊扩张术、支架、内窥镜电切术)、数字扩张术、外科手术方法(订书机狭窄成形术、经肛门环形订书机切除术、经腹重新吻合术)和皮质类固醇[3,4]。一般来说,完全/接近完全强直性脊柱炎患者首选手术治疗[1]。支架;肿瘤手术后使用支架治疗强直性脊柱炎的益处尚未得到证实[3]。不过,Philip BC Pangg 等人采用结肠/直肠内镜超声(EUS)吻合技术和热腔金属支架,非手术治疗了近完全性强直性脊柱炎[5]。我们对吻合口近乎完全狭窄的患者采用了三段式套管扩张术。一位 59 岁的女性患者因乙状结肠肿瘤接受了腹腔镜前切除术,随访时主诉腹部肿胀、间歇性腹痛和排便困难。一个月后,在进行结肠镜检查时,发现吻合口几乎完全狭窄。在导丝引导下,使用马洛尼柔性套管扩张器进行了套管扩张术。小口扩张术共进行了 3 次,每次间隔 15 天。第一次(33、36 和 42 F)和第二次(36、42 F)扩张后,通过胃镜检查可以看到吻合口狭窄的上段。第三次使用扩张器(42、45 F)扩张后,结肠镜很容易通过吻合口线到达上段。六个月后进行结肠镜检查,吻合口的近端部分在没有使用扩张器的情况下也很容易通过。球囊扩张是强直性脊柱炎患者首先使用的方法。不过,要想手术成功,必须重复几次。此外,当狭窄直径达到 1 厘米时,穿孔的风险就会增加。与套管扩张术相比,强直性脊柱炎的成功几率较低。如果球囊扩张失败,建议采用内窥镜电切术。数字扩张术:用于远端肛门直肠肛门狭窄。皮质类固醇应用:尚无大型研究。强直性脊柱炎的套管扩张术可提供触觉反馈,从而估计扩张器通过的阻力,避免穿孔。扩张器扩张法操作简单、费用低廉、并发症风险低。尤其是马洛尼柔性硅胶扩张器,可将并发症的风险降至最低。套管扩张器可以保持多年完好无损,可以重复使用。但球囊扩张器不能重复使用。在内窥镜方法失败的情况下,3-4%(完全/接近完全 AS)的患者会采用手术方法。但死亡率很高[1,4-6]。因此,可以采用 Philip BC Pang 等人的替代方法[5]。然而,由于内镜超声检查(EUS)中心有限,在吻合口狭窄的情况下,可以使用可弯曲的扩张器进行逐步扩张。您真诚的

Objective: One of the most studied topics in electronic apex locators (EALs) is the effect of root canal condition on the accuracy of EALs. In this study, the accuracy of Root ZX Mini, Raypex 6, and Apex ID in detecting root perforation was evaluated in a dry environment and in the presence of saline, ethylenediamine tetraacetic acid (EDTA), and sodium hypochlorite (NaOCl) solutions.Methods: The mesiobuccal roots of 64 human maxillary first molars were selected for the study. These root canals were perforated from buccal root surface using a #1 Freze Beutherlock Peeso to form a 0.4 mm cavity. After perforation, the area where #40 K type file appeared was recorded as the actual length (AL) and the length measured by EAL devices both in dry canals and in the presence of solutions was recorded as the electronic measurement (EL). All electronic measurements were statistically compared with the actual length.Results: All EALs achieved AL-consistent results on EL measures. Consistency was determined using Root ZX Mini measurements in dry canals and canals irrigated with saline. The consistency of EL and AL conducted with Raypex 6 and Apex ID in canals irrigated with NaOCl, saline, and EDTA was found. There was a statistically significant difference in ELs with irrigation solutions among all EALs (p<0.05). In the dry environment, there was no statistically significant difference between the EALs (p>0.05). A consistency was discovered between ELs generated with the Root ZX Mini and ALs in both dry and saline-irrigated canals. Consistency was observed between ELs measured with Raypex 6 and Apex ID and ALs in canals irrigated with NaOCl, saline, and EDTA.Conclusion: The accuracy rates of the EALs used in this research were 97%–100% in the 1 mm range and 83%–92% in the 0.5 mm range. Despite the fact that ALs and ELs differed statistically significantly at the 0.05 level, these variations weren't thought to be clinically relevant. In the presence of conditions with different electro conductors, EALs from different generations may be used safely, and in a range of canal situations, these devices can yield measurements that are most similar to the AL.
目的:电子根尖定位仪(EAL)研究最多的课题之一是根管状况对 EAL 精确度的影响。本研究评估了 Root ZX Mini、Raypex 6 和 Apex ID 在干燥环境和生理盐水、乙二胺四乙酸 (EDTA) 和次氯酸钠 (NaOCl) 溶液中检测根穿孔的准确性:研究选取了 64 颗人类上颌第一磨牙的中颊根。使用 1 号 Freze Beutherlock Peeso 从颊面根表面对这些根管进行穿孔,形成 0.4 毫米的空腔。穿孔后,40 号 K 型锉出现的区域被记录为实际长度 (AL),而在干燥根管和溶液存在的情况下通过 EAL 设备测量的长度被记录为电子测量值 (EL)。所有电子测量值都与实际长度进行了统计比较:结果:所有 EAL 在 EL 测量上都达到了与 AL 一致的结果。使用 Root ZX Mini 对干燥的根管和生理盐水灌溉的根管进行测量,可以确定测量结果的一致性。使用 Raypex 6 和 Apex ID 在用 NaOCl、生理盐水和 EDTA 灌溉的根管中进行的 EL 和 AL 测量结果一致。在所有 EAL 中,使用灌溉溶液的 EL 有显著的统计学差异(P0.05)。使用 Root ZX Mini 生成的 ELs 与干燥和盐水灌溉下的 ALs 之间具有一致性。用 Raypex 6 和 Apex ID 测量的 EL 与用 NaOCl、生理盐水和 EDTA 灌溉的牙管中的 AL 之间也有一致性:本研究中使用的 EAL 在 1 毫米范围内的准确率为 97%-100%,在 0.5 毫米范围内的准确率为 83%-92%。尽管 AL 和 EL 在 0.05 的统计学水平上存在显著差异,但这些差异被认为与临床无关。在存在不同电导体的条件下,可以安全地使用不同世代的EAL,而且在一系列的牙槽骨情况下,这些设备可以获得与AL最相似的测量结果。

Objectives: The amount of dermal filler procedures is increasing. Some patients opt to undergo dermal fillers instead of orthognathic surgery to treat unesthetic complaints from dentofacial deformities. The aim of this work is to carry out a literature review with regard to a comparison of role and limitations between aesthetic indications of orthognathic surgery and dermal fillers.Methods: A scoping review was performed according to the PRISMA-ScR guidelines on Pubmed, Web of Science and Google Scholar. A second search was conducted to highlight topics very close subjects to the main subject: the importance of social media and measures to avoid litigation in facial aesthetics.Results: Literature on the subject is very rare. Clinical facial analysis is fundamental to both procedures. Although patients wishes are important issues, facial analysis cannot be neglected due to its objectivity. Body dysmorphic disorder is considered a contraindication for both procedures. Social media is important in patient decision-making, but should not influence treatment planning by experts. Preventing litigation or reducing financial and reputational damage can be accomplished with a few simple steps.Conclusions: A helpful list of indications and particularly contraindications for orthognathic surgery and dermal fillers was drawn up. Dermal fillers must not substitute orthognathic surgery. Further studies are urgently needed to discuss this contemporary issue.
目的:皮肤填充手术的数量正在不断增加。一些患者选择接受皮肤填充术而不是正颌外科手术,以治疗颌面部畸形引起的不美观症状。这项工作的目的是就正颌外科手术和皮肤填充术在美学适应症方面的作用和局限性的比较进行文献综述:方法:根据PRISMA-ScR指南在Pubmed、Web of Science和Google Scholar上进行了范围审查。第二项搜索是为了突出与主题非常接近的主题:社交媒体的重要性和避免面部美容诉讼的措施:有关该主题的文献非常罕见。临床面部分析是两种手术的基础。尽管患者的意愿是重要问题,但面部分析的客观性不容忽视。身体畸形障碍被认为是两种手术的禁忌症。社交媒体对患者的决策很重要,但不应影响专家的治疗计划。通过几个简单的步骤就可以防止诉讼或减少经济和名誉损失:本文列出了正颌外科手术和皮肤填充剂的适应症,尤其是禁忌症。皮肤填充剂不能替代正颌外科手术。我们亟需开展更多的研究来讨论这一当代问题。

Objective: Diabetes Mellitus (DM) not only causes hyperglycemia but also leads to clinical challenges involving respiratory functional impairments. The contraction of the diaphragm reduces pleural pressure, thereby contributing significantly to the process of breathing. This study examines the functional impairments in diaphragm muscle isometric contraction parameters due to increased reactive oxygen species (ROS) associated with DM, as well as the effects of MitoTEMPO, a mitochondria-specific antioxidant, on these impairments.Methods: Wistar Albino male rats at 12-14 weeks of age were randomly divided into three groups: the control group (CON, n=6), the diabetes group (DM, n=6), and the diabetes + MitoTEMPO (MT, n=6) group. A single dose of 50 mg/kg streptozotocin (STZ) was administered to the rats in the DM and MT groups. When the rats in the MT group reached a blood glucose level of 300 mg/dl, they were administered MitoTEMPO at a dose of 0.7 mg/kg/day for 28 days. Isometric contraction recordings were obtained from diaphragm muscle preparations isolated from the experimental animals at the end of the 28-day period.Results: Although the effectiveness of mitochondria-specific antioxidants in reducing blood glucose levels in DM is debated in the literature, results for the MT group were interestingly indicative of a statistically significant decrease in blood glucose levels following MitoTEMPO administration at the end of the fourth week. Furthermore, MitoTEMPO exhibited therapeutic effects on diaphragm muscle contraction parameters impaired by DM.Conclusion: The findings suggest that in DM patients, MitoTEMPO could be utilized for blood glucose control and might also be effective in the treatment of DM-induced diaphragm muscle mechanical dysfunction.
目的:糖尿病(DM)不仅会引起高血糖,还会导致呼吸功能障碍等临床难题。膈肌的收缩可降低胸膜压力,从而对呼吸过程做出重要贡献。本研究探讨了与 DM 相关的活性氧(ROS)增加导致的膈肌等长收缩参数的功能损伤,以及线粒体特异性抗氧化剂 MitoTEMPO 对这些损伤的影响:将 12-14 周龄的 Wistar Albino 雄性大鼠随机分为三组:对照组(CON,n=6)、糖尿病组(DM,n=6)和糖尿病 + MitoTEMPO 组(MT,n=6)。给 DM 组和 MT 组大鼠注射单剂量 50 毫克/千克链脲佐菌素(STZ)。当MT组大鼠的血糖水平达到300 mg/dl时,给它们服用MitoTEMPO,剂量为0.7 mg/kg/天,持续28天。28 天结束时,从实验动物身上分离出的膈肌制备物进行等长收缩记录:虽然线粒体特异性抗氧化剂在降低 DM 中血糖水平的有效性在文献中存在争议,但 MT 组的结果有趣地表明,服用 MitoTEMPO 后,血糖水平在第四周结束时出现了统计学意义上的显著下降。此外,MitoTEMPO 对因 DM 而受损的膈肌收缩参数也有治疗作用:研究结果表明,MitoTEMPO 可用于 DM 患者的血糖控制,也可有效治疗 DM 引起的膈肌机械功能障碍。

Objective: The increasing use of electronic devices, accompanied by advancing technologies, has led to heightened exposure to non-ionizing electromagnetic radiation (EMR). This exposure instigates the accumulation of free radicals and oxidative damage in tissues, consequently impacting biological systems. Notably, the testis is among the tissues adversely affected by EMR. Numerous studies have highlighted the pivotal role of the testis in sperm production, emphasizing the potential implications of any damage on the reproductive system. This study aims to assess the levels of lipid peroxidation through histological evaluation in the testicular tissue of prepubertal male rats exposed to electromagnetic radiation at varying electric field intensities within the 2.45 GHz radiofrequency (RF) range.Methods: The experimental group comprises six subdivisions, including a sham control group, as well as groups exposed to varying electric field strengths (EFS) of 0.6 V/m, 1.9 V/m, 5 V/m, 10 V/m, and 15 V/m, respectively. Excluding the sham control group, the remaining subgroups were subjected to a daily 2.45 GHz RF exposure for 1 hour starting immediately after fertilization. This exposure to different electric field intensities continued for 45 days post-birth.Results: The samples obtained from the RF radiation-exposed rats exhibited elevated malondialdehyde (MDA) values and decreased glutathione (GSH) values in the testicular tissue. Furthermore, a comparative analysis between the microwave radiation-exposed group and the control group revealed distinct histological alterations in the testicular tissue.Conclusion: In conclusion, our findings indicate that exposure to microwave radiation at an electric field intensity of 15 V/m can lead to significant histopathological and oxidative parameter changes in Wistar rats. These results underscore the potential effects of such exposure on human health.
目的:随着技术的进步,电子设备的使用越来越多,导致非电离电磁辐射(EMR)的暴露增加。这种暴露会刺激组织中自由基的积累和氧化损伤,从而影响生物系统。值得注意的是,睾丸是EMR不利影响的组织之一。许多研究都强调了睾丸在精子产生中的关键作用,强调了任何损害生殖系统的潜在影响。本研究旨在通过组织学评估暴露于2.45 GHz射频范围内不同电场强度电磁辐射下的青春期前雄性大鼠睾丸组织脂质过氧化水平。方法:实验组分为6个小组,分别为假对照组、0.6 V/m、1.9 V/m、5 V/m、10 V/m、15 V/m的电场强度暴露组。除假对照组外,其余亚组在受精后立即开始每天接受2.45 GHz射频暴露1小时。这种不同电场强度的暴露持续了出生后45天。结果:射频辐射暴露大鼠睾丸组织中丙二醛(MDA)升高,谷胱甘肽(GSH)降低。此外,微波辐射暴露组和对照组的比较分析显示睾丸组织有明显的组织学改变。结论:综上所述,我们的研究结果表明,暴露于15 V/m电场强度的微波辐射可导致Wistar大鼠的组织病理学和氧化参数发生显著变化。这些结果强调了这种接触对人类健康的潜在影响。

Objective: Odontogenic cysts that cause bone destruction can exhibit various types of metaplasia. Inherited genetic variants in codons 72 and 175, the hotspot codons of p53, known as the guardian of the genome, can cause a wide variety of cancers. We aimed to investigate the effects of the p53 codon 72 and p53 codon 175 variants on odontogenic cyst formation.Methods: This research encompassed 71 individuals with odontogenic cysts and 90 without any conditions as a control group. After DNA was extracting, the p53 codon 72 was detected using PCR techniques, while p53 codon 175 was identified through allele-specific amplification-PCR.Results: The presence of the p53 codon 72 GG genotype and its G allele was less frequent in the group with odontogenic cysts compared to the healthy participants. Conversely, the C allele was found more often in the cyst-afflicted group. For the p53 codon 175, the AA genotype and A allele were more common in the affected group, while the G allele was more predominant in the control group.Conclusion: The p53 codon 175 AA genotype and A allele, p53 codon 72 C allele, and p53 codon 72/codon 175 CCAA combined genotype may be associated with odontagenic cyst formation. Individuals with this allele and genotype can be considered at risk for odontagenic cyst formation.
目的:引起骨破坏的牙源性囊肿可表现为各种类型的化生。密码子72和175的遗传变异,即p53的热点密码子,被称为基因组的守护者,可以导致多种癌症。我们的目的是研究p53密码子72和p53密码子175变异对牙源性囊肿形成的影响。方法:本研究纳入71例牙源性囊肿患者和90例无任何疾病的对照组。提取DNA后,采用PCR技术检测p53密码子72,采用等位基因特异性扩增-PCR技术鉴定p53密码子175。结果:牙源性囊肿组中p53密码子72gg基因型及其G等位基因的出现频率低于健康组。相反,C等位基因在囊肿患者组中更常见。p53密码子175中,AA基因型和A等位基因在患病组多见,G等位基因在对照组多见。结论:p53密码子175 AA基因型和A等位基因、p53密码子72 C等位基因、p53密码子72/ 175 CCAA联合基因型可能与牙源性囊肿的形成有关。具有该等位基因和基因型的个体可被认为具有牙原性囊肿形成的风险。

Inherited genetic variants in codons 72 and 175, the hotspot codons of p53, known as the guardian of the genome, can cause a wide variety of cancers. We aimed to investigate the effects of the p53 codon 72 and p53 codon 175 variants on odontogenic cyst formation.\u0000Methods: This research encompassed 71 individuals with odontogenic cysts and 90 without any conditions as a control group. After DNA was extracting, the p53 codon 72 was detected using PCR techniques, while p53 codon 175 was identified through allele-specific amplification-PCR.\u0000Results: The presence of the p53 codon 72 GG genotype and its G allele was less frequent in the group with odontogenic cysts compared to the healthy participants. Conversely, the C allele was found more often in the cyst-afflicted group. For the p53 codon 175, the AA genotype and A allele were more common in the affected group, while the G allele was more predominant in the control group.\u0000Conclusion: The p53 codon 175 AA genotype and A allele, p53 codon 72 C allele, and p53 codon 72/codon 175 CCAA combined genotype may be associated with odontagenic cyst formation.
