Polycystic ovary syndrome (PCOS) is a complex disorder characterized by elevated androgen levels, menstrual irregularities, and polycystic morphology of the ovaries. Affecting 6-10% of women in childbearing age, PCOS is a leading cause of infertility worldwide. In recent years, there has been a growing acknowledgment of the involvement of adenosine monophosphate-activated protein kinase (AMPK) in the development of polycystic ovary syndrome (PCOS). The expression of AMPK is diminished in polycystic ovaries, and when AMPK is silenced in human granulosa cells, there is a rise in the expression of steroidogenic enzymes, resulting in increased production of estradiol and progesterone. Additionally, in mouse models, the inhibiting AMPK intensifies the polycystic appearance of ovaries and impairs the process of ovulation. Moreover, it has been shown that AMPK activators like metformin and resveratrol ameliorate PCOS associated signs and symptoms in experimental and clinical studies. These findings, collectively, indicate the key role of AMPK in the pathogenesis of PCOS. Understanding the role of AMPK in PCOS will offer rewarding information on details of PCOS pathogenesis and will provide novel more specific therapeutic approaches. The present review summarizes the latest findings regarding the role of AMPK in PCOS obtained in experimental and clinical studies.

多囊卵巢综合征(PCOS)是一种复杂的疾病,以雄激素水平升高、月经不调和卵巢多囊形态为特征。多囊卵巢综合征影响 6-10% 的育龄妇女,是全球不孕症的主要原因。近年来,越来越多的人认识到单磷酸腺苷激活蛋白激酶(AMPK)参与了多囊卵巢综合征(PCOS)的发病。AMPK 在多囊卵巢中的表达减少,当 AMPK 在人类颗粒细胞中被沉默时,类固醇生成酶的表达上升,导致雌二醇和孕酮的生成增加。此外,在小鼠模型中,抑制 AMPK 会加剧卵巢的多囊性外观并损害排卵过程。此外,实验和临床研究还表明,二甲双胍和白藜芦醇等 AMPK 激活剂可改善多囊卵巢综合症的相关症状和体征。这些发现共同表明,AMPK 在多囊卵巢综合症的发病机制中起着关键作用。了解 AMPK 在多囊卵巢综合症中的作用将为了解多囊卵巢综合症发病机制的细节提供有价值的信息,并将提供更有针对性的新型治疗方法。本综述总结了实验和临床研究中有关 AMPK 在多囊卵巢综合症中作用的最新发现。

In this study, the role of inflammatory biomarkers and vitamin D in Type 2 diabetes mellitus (T2DM) and their correlation with diabetes related factors (HbA1c, FPG, and insulin) was analysed. In this study, Kashmiri patients with T2DM and healthy individuals were considered as cases (n = 100) and controls (n = 100) respectively. Blood samples from both groups were collected, inflammatory biomarkers (TNF-α, CRP), as well as serum vitamin D levels, were estimated by ELISA. From our results it was revealed that patients with T2DM had significantly lower serum vitamin D levels than control groups (p<0.05). Pro-inflammatory cytokine levels, including TNF-α and CRP, were seen to be elevated reaching a level of statistical significance (p<0.05). On correlating the HbA1c, FPG and insulin with TNF-α, CRP and vitamin D, significant positive correlation (p<0.05) was found between TNF-α and CRP with HbA1c and FPG in patients, non-significant positive correlation (p>0.05) was observed between insulin with TNF-α, and vitamin D and weak negative correlation with CRP in case study group. On correlating the impact of vitamin D on HbA1c and FPG levels, non-significant weak negative correlation was observed in patient group than controls, indicating that patients with lower vitamin D levels have higher HbA1c, showing that lower vitamin D have some role in etiology of T2DM.

在这项研究中,分析了炎症生物标志物和维生素 D 在 2 型糖尿病(T2DM)中的作用及其与糖尿病相关因素(HbA1c、FPG 和胰岛素)的相关性。在这项研究中,克什米尔 T2DM 患者和健康人分别被视为病例(100 人)和对照组(100 人)。研究人员采集了两组患者的血液样本,并通过 ELISA 方法估算了炎症生物标志物(TNF-α、CRP)和血清维生素 D 水平。结果显示,T2DM 患者的血清维生素 D 水平明显低于对照组(ppp>0.05),在病例研究组中,胰岛素与 TNF-α 和维生素 D 之间呈负相关,与 CRP 呈弱相关。在维生素 D 对 HbA1c 和 FPG 水平影响的相关性方面,观察到患者组比对照组存在非显著的弱负相关,表明维生素 D 水平较低的患者 HbA1c 较高,这说明维生素 D 水平较低在 T2DM 的病因中起一定作用。

Identification of Novel Biomarkers Using Serum and Urinary Proteomics for Early Detection of Hypoxic Ischemic Encephalopathy. 利用血清和尿液蛋白质组学鉴定新型生物标记物以早期检测缺氧缺血性脑病
IF 1.5 Q4 BIOCHEMISTRY & MOLECULAR BIOLOGY Pub Date : 2024-10-01 Epub Date: 2023-07-25 DOI: 10.1007/s12291-023-01143-2

Hypoxic-ischemic encephalopathy (HIE) is a severe birth complication affecting neonates. Around 40-60% of affected neonates die by two years of age or have severe disabilities and neurodevelopmental delays. The early assessments of brain injury using traditional clinical and biochemical indicators do not always align with its severity and recovery. This delays identifying neonates who may benefit from adjuvant therapeutic strategies and monitoring therapy response. Our aim was to identify specific proteins using proteomic approach to predict the severity of neonatal asphyxia so that its outcome can also be prevented. To achieve this goal a case-control study was conducted on 38 neonates, and serum and urine samples were collected within 24 h of life. Clinical findings, biochemical parameters, and outcomes of the neonates were recorded. A tandem mass spectrometry-based quantitative proteomics approach was used to identify proteins in the serum and urine of HIE neonates. Bioinformatics analyses were performed to assess the potential features and competence of the identified differentially expressed proteins. This resulted in identification of 51 differentially expressed proteins which were found common to both serum and urine proteomic data. Some of the promising biomarkers found were APOD, ORM1, SOD1, and FABP1. These proteins were associated with the pathways like Amyloid fiber formation, diseases of programmed cell death, detoxification of reactive oxygen species, and neurodegenerative diseases. This study will pave the way for identifying the biomarkers (proteins) that can screen neonates for brain injury and monitor the disease progression, which may reduce mortality and neurodevelopmental impairment.

缺氧缺血性脑病(HIE)是一种影响新生儿的严重出生并发症。约有 40-60% 的受影响新生儿在两岁前死亡或出现严重残疾和神经发育迟缓。使用传统的临床和生化指标对脑损伤进行早期评估并不总是与脑损伤的严重程度和恢复情况相一致。这就延误了识别可能受益于辅助治疗策略的新生儿和监测治疗反应的时间。我们的目的是利用蛋白质组学方法鉴定特定蛋白质,以预测新生儿窒息的严重程度,从而预防其后果。为了实现这一目标,我们对 38 名新生儿进行了病例对照研究,收集了他们出生后 24 小时内的血清和尿液样本。研究记录了新生儿的临床表现、生化指标和结局。研究采用串联质谱定量蛋白质组学方法鉴定 HIE 新生儿血清和尿液中的蛋白质。生物信息学分析评估了已识别的差异表达蛋白的潜在特征和能力。结果发现血清和尿液蛋白质组数据中共有 51 种差异表达蛋白质。发现的一些有前景的生物标记物包括 APOD、ORM1、SOD1 和 FABP1。这些蛋白质与淀粉样纤维的形成、细胞程序性死亡疾病、活性氧解毒和神经退行性疾病等途径有关。这项研究将为确定可筛查新生儿脑损伤和监测疾病进展的生物标志物(蛋白质)铺平道路,从而降低死亡率和神经发育障碍:在线版本包含补充材料,可在 10.1007/s12291-023-01143-2上获取。

This study investigated the diagnostic accuracy (DA) and clinical utility (CU) of DNA methylation (5 methylcytosine) in occupational Pb-exposure from Pb based industry. Blood Lead levels (BLLs) were measured using the ICP-OES method. The total DNA methylation (5-mC) was quantified using ELISA method. Based on their BLLs, the Pb-exposed workers were categorised into three groups: low (< 10 µg/dL), moderate (10-30 µg/dL), and high exposure (> 30 µg/dL). DNA methylation (5-mC) was significantly lower in moderate and high Pb-exposure groups when compared to the low Pb-exposure group. Workers exposed to high levels of Pb-exposure, the DA variables of 5-mC showed that the sensitivity was 74.7% [95% CI 65.4-84.0], specificity was 69.6% [95% CI 50.8-88.4], positive predictive value (PPV) was 89.9% [95% CI 82.7-97.0], Postive likelihood ratio (LR+) was 2.454 [95% CI 1.3-4.6], and diagnostic odds ratio (DOR) is 6.3 [95% CI 6.5-7.7]. In moderate Pb-exposure, the DA variables of 5-mC revealed that the sensitivity is 64.9% [95% CI 55.2-74.5], the specificity is 69.6% [95% CI 50.8-88.4], the PPV is 89.7% [95% CI 82.5-97.0], the LR+ is 2.132 [95% CI 1.13-4.03], and the DOR is 4.2 [95% CI 3.6-5.7]. The high Pb-exposure group had higher DA metrics when compared to moderate Pb exposure. The clinical utility (CU+) of 5-mC was found to have good utility of 0.671 [95% CI 0.566-0.776] in the high Pb exposure group and fair utility of 0.582 [95% CI 0.470-0.694] in moderate Pb exposure group. In conclusion, DNA methylation (5mC) could be used as a predictive biomarker for high Pb-exposure.

本研究调查了 DNA 甲基化(5 甲基胞嘧啶)在铅工业职业性铅暴露中的诊断准确性(DA)和临床实用性(CU)。采用 ICP-OES 方法测量血液铅含量 (BLL)。DNA 总甲基化(5-mC)采用 ELISA 方法进行量化。根据他们的血铅含量,受铅污染的工人被分为三组:低(30 µg/dL)组、中(30 µg/dL)组和高(30 µg/dL)组。与低铅暴露组相比,中度和高度铅暴露组的 DNA 甲基化(5-mC)明显较低。在暴露于高浓度铅的工人中,5-mC 的 DA 变量显示灵敏度为 74.7% [95% CI 65.4-84.0],特异性为 69.6% [95% CI 50.8-88.4],阳性预测值(positive predictive value,阳性预测值)为 0.5%。阳性预测值(PPV)为 89.9% [95% CI 82.7-97.0],阳性似然比(LR+)为 2.454 [95% CI 1.3-4.6],诊断几率比(DOR)为 6.3 [95% CI 6.5-7.7]。在中度铅暴露中,5-mC 的 DA 变量显示灵敏度为 64.9% [95% CI 55.2-74.5],特异性为 69.6% [95% CI 50.8-88.4],PPV 为 89.7% [95% CI 82.5-97.0],LR+ 为 2.132 [95% CI 1.13-4.03],DOR 为 4.2 [95% CI 3.6-5.7]。与中度铅暴露相比,高铅暴露组的 DA 指标更高。在高铅暴露组,5-mC 的临床实用性(CU+)为 0.671 [95% CI 0.566-0.776],良好;在中度铅暴露组,5-mC 的临床实用性为 0.582 [95% CI 0.470-0.694],一般。总之,DNA甲基化(5mC)可作为高铅暴露的预测性生物标志物。

TRAIL, a member of the TNF family, is expressed in tumor and tumor surrounding tissue in many solid organ cancers. While the induction of tumor-specific apoptosis in correlation with cytokine stimulation may cause anti-tumoral effects, the pro-tumorigenic effects of its expression by tumor surrounding tissue members have been reported in the literature. In our study, it was aimed to evaluate the effect of the gene variant of TRAIL on soluble levels in patients with colorectal cancer (CRC) on the molecular pathological axis. TRAIL C1595 gene variant PCR-RFLP and sTRAIL levels were determined by ELISA in age and sex adjusted CRC and control groups. It was determined that CT carriage was high in patients without perineural invasion and sTRAIL levels were approximately 2.72 times lower than CC in patients with CT in this group (p < 0.05). Similarly, sTRAIL level was found to be high in patients with CC genotype in CRC without lymph node metastas. It was determined that CT carriage was high in patients without perineural invasion and sTRAIL levels were approximately 2.49 times lower than CC in patients with CT in this group.is (p < 0.05). We think that TRAIL C1595T in CRC can change sTRAIL levels in the clinicopathological axis in advanced stages such as metastasis and invasion, but both are not independent risk factors.

Tramadol is a pain killing drug highly used worldwide. There is a knowledge gap for fertility consequences of analgesic addiction in men. In this observational study, we investigated the hazards of tramadol abuse on human male reproductive function. A total of 30 tramadol addicts and 30 healthy controls have participated in the study. History and clinical examination of the included subjects were performed. Biochemical and molecular assays were measured in all participants include serum reproductive hormones (calculated free testosterone, FSH, LH, prolactin and estradiol) using ELISA techniques, semen analysis, seminal plasma zinc and selenium assays using colorimetric kits, seminal plasma tramadol concentrations using Gas Chromatography-Mass Spectrometry (GC-MS), and seminal plasma 8-hydroxyguanosine (8-OHG) using high performance liquid chromatography were measured. Tramadol abuse significantly decreased semen parameters quality. Additionally, tramadol abuse significantly decreased testosterone (P = 0.001) and increased prolactin serum levels (P = 0.000). Tramadol abusers showed significantly higher levels of 8-OHG (P < 0.0001) with significantly lower levels of zinc and selenium in their seminal plasma compared with the controls (P < 0.0001, and 0.0002 respectively). Also, tramadol addicts displayed positive correlations between seminal plasma levels of 8-OHG (r = 0.905, P = 0.00) and sperm abnormal forms (r = 0.610, P = 0.000) with seminal plasma tramadol levels. Seminal plasma levels of zinc (r = - 0.815, P = 0.00), sperm motility (r = - 0.484, P = 0.007), and vitality (r = - 0.430, P = 0.018) were negatively correlated with seminal plasma levels of tramadol. Our data suggest that tramadol abuse may impair male fertility by increasing oxidative damage of sperms and reducing testosterone and the antioxidants trace elements in testicular tissues.

曲马多是一种止痛药,在全球范围内被广泛使用。关于镇痛药成瘾对男性生育能力的影响,目前还缺乏相关知识。在这项观察性研究中,我们调查了滥用曲马多对男性生殖功能的危害。共有 30 名曲马多成瘾者和 30 名健康对照者参与了这项研究。我们对研究对象进行了病史和临床检查。所有研究对象都接受了生化和分子检测,包括采用 ELISA 技术检测血清生殖激素(计算游离睾酮、FSH、LH、催乳素和雌二醇)、精液分析、采用比色试剂盒检测精浆锌和硒、采用气相色谱-质谱法(GC-MS)检测精浆曲马多浓度,以及采用高效液相色谱法检测精浆 8-羟基鸟苷(8-OHG)。滥用曲马多会明显降低精液参数质量。此外,滥用曲马多会明显降低睾酮(P = 0.001),增加催乳素血清水平(P = 0.000)。滥用曲马多者的精浆中 8-OHG 水平(P P P = 0.00)和精子异常形态(r = 0.610,P = 0.000)明显高于曲马多水平。精浆锌水平(r = - 0.815,P = 0.00)、精子活力(r = - 0.484,P = 0.007)和精子活力(r = - 0.430,P = 0.018)与精浆曲马多水平呈负相关。我们的数据表明,滥用曲马多可能会增加精子的氧化损伤,减少睾丸组织中的睾酮和抗氧化剂微量元素,从而损害男性生育能力:在线版本包含补充材料,可在 10.1007/s12291-023-01141-4上查阅。

Oroxylum indicum, a well-known traditional medicinal plant which is used to alleviate various kinds of diseases in Asia. The study aimed to identify bioactive compounds present in O. indicum stem bark using HPTLC technique. Further, the cytotoxic effects of the plant extracts were determined against HeLa (human cervical carcinoma) cell lines. The results of the study have shown the presence of the phytoconstituents such as flavonoids, phenols, tannins and steroids. MTT (3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyl tetrazolium bromide) assay showed that the ethanol, methanol and water extracts of O. indicum exhibited cytotoxic effect in HeLa cell lines with IC50 values of 119, 89.43 and 114.1 µg/mL, respectively against standard doxorubicin with IC50 value 3.895 µg/mL. The current study suggests that the methanol extract of O. indicum may offer chemopreventive properties. However, additional research is required to isolate and characterize the specific chemical entities present in O. indicum. These studies will aid in identifying a potential lead compound that holds promise as a natural anticancer agent.

Oroxylum indicum 是一种著名的传统药用植物,在亚洲被用来缓解各种疾病。该研究旨在利用 HPTLC 技术鉴定 O. indicum 茎皮中的生物活性化合物。此外,还测定了植物提取物对 HeLa(人宫颈癌)细胞系的细胞毒性作用。研究结果表明,植物中存在黄酮类、酚类、单宁酸和类固醇等植物成分。MTT(3-(4,5-二甲基噻唑-2-基)-2,5-二苯基溴化四氮唑)测定显示,O. indicum 的乙醇、甲醇和水提取物对 HeLa 细胞株具有细胞毒性作用,IC50 值分别为 119、89.43 和 114.1 µg/mL,而标准多柔比星的 IC50 值为 3.895 µg/mL。目前的研究表明,O. indicum 的甲醇提取物可能具有化学预防特性。不过,还需要进行更多的研究,以分离和鉴定 O. indicum 中存在的特定化学实体。这些研究将有助于确定有望成为天然抗癌剂的潜在先导化合物。

Assessing Performance of Martins's and Sampson's Formulae for Calculation of LDL-C in Indian Population: A Single Center Retrospective Study. 评估马丁斯公式和桑普森公式在印度人群中计算低密度脂蛋白胆固醇的性能:单中心回顾性研究
IF 1.5 Q4 BIOCHEMISTRY & MOLECULAR BIOLOGY Pub Date : 2024-10-01 Epub Date: 2023-07-07 DOI: 10.1007/s12291-023-01142-3

Various formulae had been derived to calculate the LDL-C from other lipid profile parameters to supplant the need for direct estimation. Martin's, Sampson's, and Cordova's formulae are recently derived formulae for calculating LDL-C. However, no study has been undertaken till now to verify the newer formulae viz. Martins's and Sampson's in Indian population. The retrospective cross-sectional study was carried out after obtaining approval from the Institutional Ethics Committee on human subject research. The lipid profile data were collected for a period of 17 months from January 2020 to May 2021. The formulae proposed by Friedewald, Cordova, Anandaraja, Martin, and Sampson were used to assess calculated LDL-C. Intraclass correlations were performed to assess the effectiveness of each formula when compared with direct estimation. In our study, we observed that LDL-C calculated using Martin was observed to be closer to that of direct estimation. The bias observed was lowest for Martin's formulae, followed by Sampson's. Intraclass correlation analysis for absolute agreement demonstrated Cordova, Martin, and Sampson to have an average ICC > 0.9, with Martin, and Sampson having a p value < 0.05. Martin fared superior to other formulae in intraclass correlation in patients with LDL > 70. In patients with TG below 200 mg/dL, Martin, and Sampson had a significant correlation with comparable average ICC. However, in patients with TG > 300 mg/dL, Cordova appears to fare better than all other formulae. Our study demonstrated a distinctly superior performance of Martin's formula over Friedewald's formula in the Indian patient population.

为了取代直接估算的需要,人们推导出了各种公式,根据其他血脂特征参数计算低密度脂蛋白胆固醇。马丁公式、桑普森公式和科尔多瓦公式是最近推导出的低密度脂蛋白胆固醇计算公式。然而,迄今为止还没有研究在印度人群中验证较新的公式,即马丁斯公式和桑普森公式。这项回顾性横断面研究是在获得人体研究机构伦理委员会批准后进行的。从 2020 年 1 月到 2021 年 5 月,共收集了 17 个月的血脂数据。弗里德瓦尔德(Friedewald)、科尔多瓦(Cordova)、阿南达拉贾(Anandaraja)、马丁(Martin)和桑普森(Sampson)提出的公式用于评估计算出的低密度脂蛋白胆固醇。通过类内相关性来评估每种公式与直接估算法相比的有效性。在我们的研究中,我们发现使用马丁公式计算出的 LDL-C 更接近直接估算值。马丁公式的偏差最小,桑普森公式次之。绝对一致的类内相关分析表明,科尔多瓦、马丁和桑普森的平均 ICC > 0.9,马丁和桑普森的 P 值为 70。在总胆固醇低于 200 毫克/分升的患者中,马丁和桑普森具有显著的相关性,平均 ICC 值相当。然而,在总胆固醇大于 300 毫克/分升的患者中,Cordova 似乎优于所有其他公式。我们的研究表明,在印度患者群体中,马丁公式的性能明显优于弗里德瓦尔德公式。
