Diabetes mellitus (DM), which affects a substantial portion of the population and has become more common in modern society, is actually a metabolic condition. The hallmark of diabetes mellitus is excessively high blood sugar levels brought on by a breakdown in glucose homeostasis brought on by a partial or complete lack of insulin in the body or by insulin activity. Hyperglycaemia is caused by changes in insulin levels or activity as well as cell activities that affect the biochemical processes involved in the metabolism of carbohydrates, proteins, and lipids in target organs like the liver function. skeletal muscle, kidney, and adipose tissue. 1.5 million deaths per year are attributed to diabetes, and 48 percent of these fatalities occurring before the age of 70. Premature mortality from diabetes increased by 5% between the years 2000 and 2016. Therefore, it's essential to pick the appropriate diabetic therapy. Professional anti-diabetic medications are available to treat diabetes, however there are significant concerns over their cost and side effects. The drawbacks of currently available drugs necessitate the development of new, less expensive, and safer remedies. While Anisomeles malabarica (A. malabarica), an indigenous medicinal plant, has been shown to have anti-epileptic, anti-diabetic, anti-proliferative, and other qualities, the focus of this review is on AM's anti-diabetic advantages.
糖尿病(DM)实际上是一种新陈代谢疾病,影响着相当一部分人口,在现代社会已变得越来越普遍。糖尿病的特征是由于体内胰岛素部分或完全缺乏或胰岛素活性导致葡萄糖平衡失调,从而引起血糖水平过高。高血糖是由于胰岛素水平或活性以及细胞活动发生变化,影响了肝功能、骨骼肌、肾脏和脂肪组织等目标器官中碳水化合物、蛋白质和脂质代谢的生化过程。每年有 150 万人死于糖尿病,其中 48% 的死亡发生在 70 岁之前。从 2000 年到 2016 年,糖尿病导致的过早死亡增加了 5%。因此,选择合适的糖尿病治疗方法至关重要。目前已有治疗糖尿病的专业抗糖尿病药物,但人们对这些药物的成本和副作用非常担忧。由于现有药物的缺点,有必要开发成本更低、更安全的新疗法。Anisomeles malabarica(A. malabarica)是一种本地药用植物,已被证明具有抗癫痫、抗糖尿病、抗增殖等功效,本综述的重点是 AM 的抗糖尿病优势。

Sensory neural hearing loss (SNHL) is a pervasive audiological disorder characterized by damage to the inner ear's hair cells or auditory nerve. Despite extensive research efforts, SNHL treatment remains a challenge due to various barriers, including limited drug penetration into the inner ear and the risk of systemic side effects. This abstract explores the innovative use of nanoparticles in intratympanic drug delivery as a promising solution to overcome these hurdles. Nanoparticles offer a unique platform for drug delivery to the inner ear, enhancing bioavailability and ensuring bioequivalence of therapeutic agents. Through targeted delivery, controlled release, and drug protection, nanoparticles address critical limitations in traditional SNHL treatments. These abstract reviews the barriers to SNHL treatment, the advantages of nanoparticle-based delivery systems, and their potential to revolutionize the management of SNHL. Further research in this field promises to unlock new opportunities for more effective and accessible treatments for SNHL patients
感觉神经性听力损失(SNHL)是一种普遍存在的听觉障碍,其特征是内耳毛细胞或听神经受损。尽管开展了大量的研究工作,但由于各种障碍,包括药物在内耳的渗透有限以及全身副作用的风险,SNHL 的治疗仍然是一项挑战。本摘要探讨了纳米颗粒在鼓室内给药中的创新应用,以此作为克服这些障碍的一种有希望的解决方案。纳米颗粒为内耳给药提供了一个独特的平台,可提高生物利用度并确保治疗药物的生物等效性。通过靶向给药、控制释放和药物保护,纳米颗粒解决了传统内耳道阻塞性硬化症治疗方法的关键局限性。本摘要回顾了SNHL治疗的障碍、基于纳米颗粒的给药系统的优势及其彻底改变SNHL治疗的潜力。该领域的进一步研究有望为 SNHL 患者带来更有效、更方便的治疗新机遇。

Thymol is a naturally occurring compound found in the essential oils of thyme, oregano, and other plants. It has been shown to have a variety of pharmacological activities, including antimicrobial, antioxidant, and anti-inflammatory properties. In recent years, researchers have investigated the potential of thymol as an anticancer agent. However, thymol has limited solubility and poor bioavailability, which limits its use as a therapeutic agent. To overcome these limitations, researchers have developed various nano-based drug delivery systems (NDDS) to improve the efficacy of thymol. In this article, we will review the current state of research on thymol NDDS with anti-tumor activity.
百里酚是一种天然化合物,存在于百里香、牛至和其他植物的精油中。它已被证明具有多种药理活性,包括抗菌、抗氧化和抗炎特性。近年来,研究人员对百里酚作为抗癌剂的潜力进行了研究。然而,百里酚的溶解度有限,生物利用度较低,这限制了它作为治疗剂的使用。为了克服这些限制,研究人员开发了各种纳米给药系统(NDDS),以提高百里酚的疗效。本文将回顾具有抗肿瘤活性的百里酚 NDDS 的研究现状。

The aim of this study was to prepare and evaluate solid lipid nanoparticles for the skin delivery of Ciprofloxacin. Ciprofloxacin loaded solid lipid nanoparticles (SLNs) have been successfully developed by using a microemulsion technique. Three different formulations were prepared It was found that variation in the amount of ingredients had profound effects on the Ciprofloxacin loading capacity, mean particle size, size distribution of charge, morphology, and drug-lipid compatibility. At optimized process conditions, Ciprofloxacin loaded SLNs showed spherical particles with a mean particle size of 250 ɳm and 60% Ciprofloxacin incorporation efficacy was achieved. The SLN sustained the drug release for 6 h in vitro. The results suggest formulation could be used as a potential topical formulation for fungal infection.

This study objective was to determine the bioequivalence of two Favipiravir 200 mg Film-Coated Tablet formulations (test and reference formulation). This study was an open label, randomized, single-dose, two-period, two-sequences, crossover study under fasting condition which included 30 healthy Indonesian volunteers. The participants were informed about this study and provided written consent. Subjects were fasted for at least 8 hours before receiving the test and reference drugs. Blood samples were collected at 17 different time points, including prior to drug administration and at various intervals up to 24 hours after drug administration. Favipiravir plasma concentrations were determined using an LC-MS/MS method. The main pharmacokinetic parameters calculated, namely the area under the plasma concentration-time curve (AUC0-t) and maximum plasma concentration (Cmax), are expected to demonstrate bioequivalence. The bioequivalence acceptance range is 80.00%- 125.00% for the 90% confidence interval of the geometric least square means ratio for AUC0-t and Cmax. The mean ± SD values for AUC0-24 and Cmax of the test drug were 15,756.77± 4,773.47 ng·mL-1·hr and 7,237.49 ± 1,441.07 ng/mL, respectively. The mean ± SD values for AUC0-24 and Cmax of the Reference drug were 15,491.62 ± 4,288.43 ng·mL-1·hr and 7,218.51 ± 1,896.11 ng/mL, respectively. The geometric mean ratio of the test drug to the Reference drug (90% CI) was 101.27% (96.89-105.86) for AUC0-24 and 101.22% (96.80-105.84) for Cmax. The results of this study in healthy indonesian volunteers indicate that Favipiravir 200 mg Film-Coated Tablet manufactured by PT Kimia Farma Tbk are bioequivalent to the reference product — Avigan® 200 mg mg Film-Coated Tablet manufactured by Fujifilm Toyama Chemical Co., Ltd.
本研究旨在确定两种法维拉韦 200 毫克薄膜衣片制剂(试验制剂和参比制剂)的生物等效性。本研究是一项开放标签、随机、单剂量、两周期、两序列、空腹交叉研究,共纳入 30 名健康的印尼志愿者。受试者已被告知这项研究并提交了书面同意书。受试者在接受试验药物和参照药物前至少禁食 8 小时。在 17 个不同的时间点采集血样,包括用药前和用药后 24 小时内的不同时间间隔。采用 LC-MS/MS 方法测定法维拉韦的血浆浓度。计算出的主要药代动力学参数,即血浆浓度-时间曲线下面积(AUC0-t)和最大血浆浓度(Cmax),有望证明生物等效性。在 AUC0-t 和 Cmax 的几何最小平方均值比的 90% 置信区间内,生物等效性的接受范围为 80.00% - 125.00%。试验药物 AUC0-24 和 Cmax 的平均值(± SD)分别为 15,756.77±4,773.47 ng-mL-1-hr 和 7,237.49±1,441.07 ng/mL。参比药物的 AUC0-24 和 Cmax 的平均值(± SD)分别为 15,491.62 ± 4,288.43 ng-mL-1-hr 和 7,218.51 ± 1,896.11 ng/mL。试验药物与参考药物的几何平均比值(90% CI)为:AUC0-24 为 101.27% (96.89-105.86),Cmax 为 101.22% (96.80-105.84)。在印度尼西亚健康志愿者中进行的这项研究结果表明,PT Kimia Farma Tbk 公司生产的法维拉韦 200 毫克薄膜衣片与富士胶片富山化学株式会社生产的参比产品 Avigan® 200 毫克薄膜衣片具有生物等效性。

Pub Date : 2023-07-04 DOI: 10.23880/beba-16000203
Mancini-Filho J
The phenolic compounds present in food cover a wide range of structures that have different biological properties. Highlighting its antioxidant properties and the presence mainly of spices, herbs and other foods. Some compounds present in spices can be listed for their antioxidant activity, such as: cloves have eugenol, pinene in their composition, cinnamon also has eugenol, limonene, pinene, catechins and other phenolic compounds in their composition, anise has pinene, rutin, apigenin, oregano has apigenin, quercecin, rosmarinic, caffeic, p-coumaric acids, and others. Rosemary presents the carnosic, rosmarinic, caffeic and hydroxycinnamic. The tissue inflammatory process normally starts with the presence of free radicals that are associated with the oxidative process activated by reactive oxygen species represented by peroxides, superoxide ion, presence of hydroxyl radical, singlet oxygen, among others. The highlighted phenolic compounds have in their structure one or more hydroxyls that have the property of donating a hydrogen atom to free radical structures, which can block the triggering of the oxidative process and thus inflammation.

Low-grade gliomas are among the most common CNS tumors in the pediatric patients group. From the genetics, histopathology, treatment strategies, distribution and molecular points of view, these tumors are different from ones which can be seen in the adult patients group. From the histological point of view, low-grade gliomas in the pediatric patients group encompass tumors of oligodendroglial, astrocytic and mixed glial-neuronal histology. Transforming into malignancy would usually not occur in most of these tumors. Understanding the genetics of these tumors is of importance in learning their behaviors. This brief review tries to point to some important notes about the genetics of the low-grade gliomas in the pediatric patients group.
低级别胶质瘤是儿科最常见的中枢神经系统肿瘤之一。从遗传学、组织病理学、治疗策略、分布和分子角度来看,这些肿瘤都与成人患者群体中的肿瘤不同。从组织学角度看,儿童低级别胶质瘤包括少突胶质细胞、星形胶质细胞和胶质-神经元混合组织学肿瘤。大多数此类肿瘤通常不会转化为恶性肿瘤。了解这些肿瘤的遗传学对了解它们的行为非常重要。这篇简短的综述试图指出儿科低级别胶质瘤遗传学的一些重要注意事项。

Zidovudine is a synthetic nucleoside analogue, specifically a nucleoside reverse transcriptase inhibitor (NRTI), that inhibits the replication of retroviruses, including HIV. Study Objective: This study objective was to determine the bioequivalence of Zidovudine 100 mg capsules produced by PT Kimia Farma Tbk compared to Retrovir 100 mg capsules produced by GlaxoSmithKline Pharmaceuticals S.A, in healthy subjects Methods: The study was conducted in a randomized, single-dose, open-label, two-way crossover design (2 treatments, 2 periods, and 2 sequences) under fasting state with 7 (seven) days washed-out period between each period. The number of subjects who participated and completed the study were 31 of 32 adult male and female. One subject dropped out from 2nd period because of personal reason. The subjects received an explanation of the study and signed informed consent. Subjects fasted for a minimum of 8 hours before receiving the test drug and reference drug. Blood samples were collected 15 times at the following time points: 0 hours (before drug administration), 0.16, 0.33, 0.50, 0.75, 1, 1.5, 2, 2.5, 3, 4, 5, 6, 8, and 10 hours after drug administration. Plasma concentrations of the drug were determined by LC-MS/MS method. The pharmacokinetic parameters calculated in this study are AUC0-t, AUC0-inf, Cmax, tmax, and t½, while the statistical interval proposed was 80.00 - 125.00% for AUC0-t and Cmax with 90% Confidence Interval (CI) with α = 5.00%. Results: The main pharmacokinetic parameters of the test drug Zidovudine (BN: G2 1346 J) compared to reference drug, Retrovir (BN: JN8K) were calculated based on geometric mean ratio and 90% confidence interval (CI). The results for AUC0-t and Cmax were 101.65% (96.77- 106.83%) and 95.63% (84.09-108.76%) respectively, with intra-subject variability (%CV) for AUC0-t and Cmax were 11.49% and 30.47%. Hence, the number of 31 subjects has adequate number for required power of study. Conclusion: Based on the AUC0-t and Cmax values, Zidovudine 100 mg Capsules Produced by PT. Kimia Farma Tbk is bioequivalent to Retrovir 100 mg Capsules Produced by GlaxoSmithKline Pharmaceuticals S.A.

Epidemiological studies have consistently linked abundant consumption of foods of plant origin, to the reduced risk of cancer. The present study was conducted to perform the of chemical and phytochemical characterization of selected medicinal herbs Centella asiatica and Cymbopogan citratus which are commonly used in Malaysian diet. Phytochemical and chemical characterization of the plant extracts were determined by qualitative phytochemical analysis, HPLC analysis and GC-TOFMS analysis. The results from the phytochemical analysis indicated the presence of saponin, anthroquinone, flavonoid, tannin, alkaloid in Centella asiatica: reducing sugar, saponins, flavonoid, tannin, alkaloids in Cymbopogan citratus. In addition, the GC spectrum of Cymbopogan citratus indicated monoterpenes and cyclic terpenes, aromatic amine and alcohols and fatty acid methyl ester. Further, the GC spectrum of Centella asiatica indicated mono and cyclic terpenes and terpenoid alcohols, aromatic amine, alcohols and alkanes, caryophyllene and steroids. Since the major phytochemicals and chemicals identified in the tested plants are found to be chemopreventive and chemotherapeutic agents with antioxidant, anti-inflammatory potential and anti-tumor potential, the plants investigated may be recommended as good candidates for cytotoxicity and antiangiogenic potential.
