Introduction: In this study, an in situ gel-forming chitosan hydrogel was prepared with the use of glutamate salt of chitosan (Ch-Ga), β-glycerophosphate (Gp), and morphine (Mor). The paper is focused on in vitro physicochemical properties and in-vivo analgesic effects of the prepared chitosan hydrogel.
Method: The thermosensitive properties of prepared chitosan hydrogel were evaluated during the different temperatures and times. The physicochemical properties of chitosan hydrogel were investigated by infrared (IR) spectroscopy and X-ray diffraction analysis (XRD). Also, its cell cytotoxicity effects were evaluated in murine NIH/3T3 normal cells. Subsequently, the distribution of chitosan hydrogel in the nasal cavity of rats and its analgesic responses were evaluated. The prepared chitosan hydrogel showed that it could be gelled at the temperature of 34 °C before leaving the nose in the shortest possible time of 30 s.
Result: The analgesic responses of the intranasal (IN) injection of chitosan hydrogel (IN-chitosan hydrogel, 10 mg Mor/kg) in a single unit dose in rat relative to the placebo and intranasal or intraperitoneal (IP) injection of free morphine solution (IN-Free Mor or IP-Free Mor, 10 mg Mor/kg) via the hot plate test, reveal that the IN-chitosan hydrogel could induce fast analgesic effects of morphine with maximum possible effect (MPE) of 93% after 5 min compare to the IN-Free Mor and IP-Free Mor with MPE of 80% after 15 min and 66% after 30 min, respectively. Also, prolonged analgesic effects with MPE of 78 % after 6 h of injection were only seen in the IN-chitosan hydrogel injected group. The obtained fluorescent images of rat's brain injected with IN-chitosan hydrogel containing doxorubicine (Dox) as a fluorescent agent showed that the mucosal adhesive and absorption enhancer properties of IN-chitosan hydrogel resulting in longer presence of them in the nasal cavity of rats followed by more absorption of Dox from the blood vessels of olfactory bulbs with a 74% color intensity compared to the IN-Free Mor and IN-Free Dox with 15%.
Conclusion: These data reveal that the IN-chitosan hydrogel could induce fast and prolonged analgesic effects of morphine compare to the IN/IP-Free Mor, which could be considered as an in situ gel-forming thermosensitive chitosan hydrogel for nasal delivery of wide ranges of therapeutic agents.
简介本研究利用壳聚糖谷氨酸盐(Ch-Ga)、β-甘油磷酸酯(Gp)和吗啡(Mor)制备了一种原位凝胶化壳聚糖水凝胶。本文主要研究了所制备壳聚糖水凝胶的体外理化性质和体内镇痛效果:方法:对制备的壳聚糖水凝胶在不同温度和时间下的热敏性能进行了评估。通过红外光谱和 X 射线衍射分析研究了壳聚糖水凝胶的理化性质。此外,还在小鼠 NIH/3T3 正常细胞中评估了其细胞毒性效应。随后,对壳聚糖水凝胶在大鼠鼻腔中的分布及其镇痛反应进行了评估。结果显示,制备的壳聚糖水凝胶可在 34 °C 的温度下凝胶化,然后在 30 秒的最短时间内离开鼻腔:结果:大鼠鼻内注射壳聚糖水凝胶(IN-壳聚糖水凝胶,10 毫克吗啡/千克)的单剂量镇痛反应优于安慰剂和鼻内或腹腔内注射游离吗啡溶液(IN-游离吗啡或 IP-游离吗啡,10 毫克吗啡/千克)的单剂量镇痛反应、通过热板试验,IN-壳聚糖水凝胶可诱导吗啡的快速镇痛效应,5 分钟后的最大可能效应(MPE)为 93%,而 IN-Free Mor 和 IP-Free Mor 的最大可能效应(MPE)分别为 15 分钟后的 80% 和 30 分钟后的 66%。此外,只有注射 IN-壳聚糖水凝胶组的镇痛效果更持久,注射 6 小时后的 MPE 为 78%。大鼠脑部注射含有多柔比星(Dox)荧光剂的 IN-壳聚糖水凝胶后获得的荧光图像显示,IN-壳聚糖水凝胶的粘膜粘附性和吸收增强特性使其在大鼠鼻腔中的存在时间更长,随后嗅球血管对 Dox 的吸收更多,颜色强度达到 74%,而 IN-Free Mor 和 IN-Free Dox 的颜色强度仅为 15%:这些数据表明,与 IN/IP-Free Mor 相比,IN-壳聚糖水凝胶可诱导吗啡产生快速而持久的镇痛效果,可被视为一种原位凝胶热敏壳聚糖水凝胶,用于鼻腔输送各种治疗药物。

The stratum corneum continues to pose the biggest obstacle to transdermal drug delivery. Chemical penetrant, the first generation of transdermal drug delivery system, offers a lot of potential. In order to fully examine the permeation mechanism of 1,8-cineole, a natural monoterpene, this review summarizes the effects of permeation-enhancing medications on drugs that are lipophilic and hydrophilic as well as the toxicity of this substance on the skin and other tissues. For lower lipophilic drugs, 1,8-cineole appears to have a stronger osmotic-enhancing impact. An efficient and secure tactic would be to combine enhancers and dose forms. 1,8-cineole is anticipated to be further developed in the transdermal drug delivery system and even become a candidate drug for brain transport due to its permeability and low toxicity.

Introduction: Rheumatoid arthritis (RA) is a chronic inflammatory autoimmune disease that initially affects small joints and then spreads to the bigger joints. It also affects other organs of the body such as lungs, eyes, kidneys, heart, and skin. In RA, there is destruction of cartilage and joints, and ligaments and tendons become brittle. Damage to the joints leads to abnormalities and bone degradation, which may be quite painful for the patient.
Method: The nano-carriers such as liposomes, phytosomes, nanoparticles, microcapsules, and niosomes are developed to deliver the encapsulated phytoconstituents to targeted sites for the better management of RA.
Results: The phytoconstituents loaded nano-carriers have been used in order to increase bioavailability, stability and reduce the dose of an active compound. In one study, the curcumin-loaded phytosomes increase the bioavailability of curcumin and also provides relief from RA symptoms. The drug-loaded nano-carriers are the better option for the management of RA.
Conclusion: In conclusion, there are many anti-arthritic herbal and synthetic medicine available in the market that are currently used in the treatment of RA. However, chronic use of these medications may result in a variety of side effects. Because therapy for RA is frequently necessary for the rest of ones life. The use of natural products may be a better option for RA management. These phytoconstituents, however, have several disadvantages, including limited bioavailability, low stability, and the need for a greater dosage. These problems can be rectified by using nano-technology.
导言类风湿性关节炎(RA)是一种慢性炎症性自身免疫疾病,最初会影响小关节,然后扩散到大关节。它还会影响身体的其他器官,如肺、眼睛、肾脏、心脏和皮肤。患上 RA 后,软骨和关节会遭到破坏,韧带和肌腱也会变脆。关节受损会导致畸形和骨质退化,这可能会给患者带来相当大的痛苦:方法:开发纳米载体,如脂质体、植物载体、纳米颗粒、微胶囊和niosomes,将封装的植物成分输送到目标部位,以更好地治疗RA:结果:载入纳米载体的植物成分已被用于提高生物利用度、稳定性和减少活性化合物的剂量。在一项研究中,载入姜黄素的植物载体提高了姜黄素的生物利用率,还能缓解 RA 症状。载药纳米载体是治疗风湿性关节炎的更好选择:总之,目前市场上有许多抗关节炎的草药和合成药物可用于治疗 RA。然而,长期使用这些药物可能会导致各种副作用。因为 RA 的治疗往往需要终生进行。使用天然产品可能是治疗 RA 的更好选择。然而,这些植物成分有几个缺点,包括生物利用度有限、稳定性低和需要更大的剂量。利用纳米技术可以解决这些问题。

Magnetotactic bacteria (MTBs) and their organelles, magnetosomes, are intriguing options that might fulfill the criteria of using bacterial magnetosomes (BMs). The ferromagnetic crystals contained in BMs can condition the magnetotaxis of MTBs, which is common in water storage facilities. This review provides an overview of the feasibility of using MTBs and BMs as nanocarriers in cancer treatment. More evidence suggests that MTBs and BMs can be used as natural nanocarriers for conventional anticancer medicines, antibodies, vaccine DNA, and siRNA. In addition to improving the stability of chemotherapeutics, their usage as transporters opens the possibilities for the targeted delivery of single ligands or combinations of ligands to malignant tumors. Magnetosome magnetite crystals are different from chemically made magnetite nanoparticles (NPs) because they are strong single-magnetic domains that stay magnetized even at room temperature. They also have a narrow size range and a uniform crystal morphology. These chemical and physical properties are essential for their usage in biotechnology and nanomedicine. Bioremediation, cell separation, DNA or antigen regeneration, therapeutic agents, enzyme immobilization, magnetic hyperthermia, and contrast enhancement of magnetic resonance are just a few examples of the many uses for magnetite-producing MTB, magnetite magnetosomes, and magnetosome magnetite crystals. From 2004 to 2022, data mining of the Scopus and Web of Science databases showed that most research using magnetite from MTB was carried out for biological reasons, such as in magnetic hyperthermia and drug delivery.
趋磁细菌(MTBs)及其细胞器--磁小体,是可能符合细菌磁小体(BMs)使用标准的令人感兴趣的选择。磁小体中含有的铁磁晶体可以调节 MTB 的磁向性,这在储水设施中很常见。本综述概述了在癌症治疗中使用 MTB 和 BM 作为纳米载体的可行性。更多证据表明,MTB 和 BMs 可用作常规抗癌药物、抗体、疫苗 DNA 和 siRNA 的天然纳米载体。除了提高化疗药物的稳定性外,将它们用作转运体还为向恶性肿瘤靶向输送单一配体或配体组合提供了可能性。磁小体磁铁矿晶体不同于化学制造的磁铁矿纳米颗粒(NPs),因为它们是即使在室温下也能保持磁化的强单磁畴。它们还具有较窄的尺寸范围和均匀的晶体形态。这些化学和物理特性对它们在生物技术和纳米医学中的应用至关重要。生物修复、细胞分离、DNA 或抗原再生、治疗剂、酶固定化、磁性热疗和磁共振对比度增强只是产生磁铁矿的 MTB、磁铁矿磁小体和磁小体磁铁矿晶体众多用途中的几个例子。从 2004 年到 2022 年,对 Scopus 和 Web of Science 数据库进行的数据挖掘显示,利用 MTB 产生的磁铁矿进行的大多数研究都是出于生物学原因,如磁性热疗和药物输送。

The delivery of drugs to the brain is quite challenging in the treatment of the central nervous system (CNS) diseases due to the blood-brain barrier and the blood-cerebrospinal fluid barrier. However, significant developments in nanomaterials employed by nanoparticle drug-delivery systems have substantial potential to cross or bypass these barriers leading to enhanced therapeutic efficacies. Advances in nanoplatform, nanosystems based on lipids, polymers and inorganic materials have been extensively studied and applied in treating Alzheimer's and Parkinson's diseases. In this review, various types of brain drug delivery nanocarriers are classified, summarized, and their potential as drug delivery systems in Alzheimer's and Parkinson's diseases is discussed. Finally, challenges facing the clinical translation of nanoparticles from bench to bedside are highlighted.

Background: Liposomal Doxorubicin (Doxil®) was one of the first nanoformulations approved for the treatment of solid tumors. Although there is already extensive experience in its use for different tumors, there is currently no grouped evidence of its therapeutic benefits in non-small cell lung cancer (NSCLC). A systematic review of the literature was performed on the therapeutic effectiveness and benefits of Liposomal Doxil® in NSCLC. Methods: A total of 1022 articles were identified in publications up to 2020 (MEDLINE, Cochrane, Web of Science Core Collection and Scopus). After applying inclusion criteria, the number was restricted to 114, of which 48 assays, including in vitro (n=20) and in vivo (animals, n=35 and humans, n=6) studies, were selected. Results: The maximum inhibitory concentration (IC50), tumor growth inhibition rate, response and survival rates were the main indices for evaluating the efficacy and effectiveness of Liposomal DOX. These have shown clear benefits both in vitro and in vivo, improving the IC50 of free DOX or untargeted liposomes, depending on their size, administration, or targeting. Conclusion: Doxil® significantly reduced cellular proliferation in vitro and improved survival in vivo in both experimental animals and NSCLC patients, demonstrating optimal safety and pharmacokinetic behavior indices. Although our systematic review supports its benefits for the treatment of NSCLC, additional clinical trials with larger sample sizes are necessary to obtain more precise clinical data on its activity and effects in humans.

Abstract:: With the acceleration of people's pace of life, non-alcoholic fatty liver disease (NAFLD) has become the most common chronic liver disease in the world, which greatly threatens people's health and safety. Therefore, there is still an urgent need for higher-quality research and treatment in this area. Nuclear factor Red-2-related factor 2 (Nrf2), as a key transcription factor in the regulation of oxidative stress, plays an important role in inducing the body's antioxidant response. Although there are no approved drugs targeting Nrf2 to treat NAFLD so far, it is still of great significance to target Nrf2 to alleviate NAFLD. In recent years, studies have reported that many natural products treat NAFLD by acting on Nrf2 or Nrf2 pathways. This article reviews the role of Nrf2 in the pathogenesis of NAFLD and summarizes the currently reported natural products targeting Nrf2 or Nrf2 pathway for the treatment of NAFLD, which provides new ideas for the development of new NAFLD-related drugs.

Abstract: The field of microfluidics encompasses the study of fluid behavior within micro-channels and the development of miniature systems featuring internal compartments or passageways tailored for fluid control and manipulation. Microfluidic devices capitalize on the unique chemical and physical properties exhibited by fluids at the microscopic scale. In contrast to their larger counterparts, microfluidic systems offer a multitude of advantages. Their implementation facilitates the investigation and utilization of reduced sample, solvent, and reagent volumes, thus yielding decreased operational expenses. Owing to their compact dimensions, these devices allow for the concurrent execution of multiple procedures, leading to expedited experimental timelines. Over the past two decades, microfluidics has undergone remarkable advancements, evolving into a multifaceted discipline. Subfields such as organ-on-a-chip and paper-based microfluidics have matured into distinct fields of study. Nonetheless, while scientific progress within the microfluidics realm has been notable, its translation into autonomous end-user applications remains a frontier to be fully explored. This paper sets forth the central objective of scrutinizing the present research paradigm, prevailing limitations, and potential prospects of customizable microfluidic devices. Our inquiry revolves around the latest strides achieved, prevailing constraints, and conceivable trajectories for adaptable microfluidic technologies. We meticulously delineate existing iterations of microfluidic systems, elucidate their operational principles, deliberate upon encountered limitations, and provide a visionary outlook toward the future trajectory of microfluidic advancements. In summation, this work endeavors to shed light on the current state of microfluidic systems, underscore their operative intricacies, address incumbent challenges, and unveil promising pathways that chart the course toward the next frontier of microfluidic innovation.

Background: The tear ferning test can be an easy clinical procedure for the evaluation and characterization of the ocular tear film Objective: The objective of this study was to examine the restoration of tear ferning pattern and reduction of glycosylation peak after amlodipine application in carrageenan-induced conjunctivitis. Methods: At the rabbit’s upper palpebral region, carrageenan was injected for cytokine-mediated conjunctivitis. Ferning pattern and glycosylation of the tear fluid were characterized using various instrumental analyses. The effect of amlodipine was also examined after ocular instillation and flexible docking studies. Results: Optical microscopy showed a disrupted ferning of the tear collected from the inflamed eye. FTIR of the induced tear fluid exhibited peaks within 1000-1200 cm-1 , which might be due to the protein glycosylation, which was absent in the normal tear spectrogram. The glycosylation peak reduced significantly in the tear sample collected from the amlodipine-treated group. Corresponding energy dispersive analysis showed the presence of sulphur, indicating protein leakage from the lacrimal gland in the induced group. The disappearance of sulphur from the treated group indicated its remedial effect. The flexible docking studies revealed a stronger binding mode of amlodipine with Interleukin-1β (IL-1β). The reduction in the intensity of the glycosylated peak and the restoration offering is probably due to suppression of IL-1β. Conclusion: This study may be helpful in obtaining primary information for drug discovery to be effective against IL-1β and proving tear fluid as a novel diagnostic biomarker.

Introduction: In recent decades, drug delivery applications have extensively utilized hydrogel systems based on natural polymers. Among the numerous biopolymer-based hydrogel drug delivery systems reported, a novel pectin-like substance was extracted from fig leaves and copolymerized with chitosan.
Method: The hydrogel was reformed into microspheres using glutaraldehyde (chemical cross-linker) and sodium hexametaphosphate (physical cross-linker). The extracted polysaccharide and the prepared hydrogels were characterized by FTIR, GC/MS, SEC/MALS/DRI as well as XRD, SEM, BET, and thermal analysis. SEM images revealed the formation of porous microspheres with an average size of 50 μm in diameter. Degrees of swelling in pH7 at 35°C have shown the hydrogels reached two to three times their weights. This has been reflected in their ability to load drugs or any other chemicals. The loading formula shows that hydrogels have maximum loading efficiency more than one-third of the weight of hydrogel. The antimicrobial ciprofloxacin was used as a model for loading on prepared hydrogels. The loaded hydrogels were tested for their biological activities against staphylococcus aureus (S. aureus) bacteria. The antimicrobial growth inhibition zone of the cultured (S. aureus) by ciprofloxacin-loaded hydrogel was followed, which shows controlled growth in inhibition zone sizes and for long time intervals. Results showed that the pectin-chitosan hydrogels exhibited significant antibacterial activity against gram - positive bacteria (S. aureus), with an inhibition zone of 45 mm for (CH-co-FLP)/GLU hydrogel.
Result: In vitro, the ciprofloxacin-loaded hydrogels were studied and the cumulative release of ciprofloxacin under suitable conditions was found in a controlled manner and kept release for a long time interval. Data exhibited that the cumulative release profile of ciprofloxacin from the hydrogel demonstrated sustained release over 48 hours, with a value of 6.9% released within the first 24 hours and 7.0 and 6.9% % released at the end of the study for the (CH-co-FLP)/GLU and (CH-co-FLP)/SMP hydrogels, respectively.
Conclusion: The novel pectin-chitosan hydrogels hold the potential to enhance the quality of life for numerous patients by minimizing the need for frequent intake of chronic medications.
