Introduction: Among the many ongoing difficulties, Candida infections present significant clinical hurdles due to the rapid development of resistance, recurrent episodes, and the limited effectiveness of conventional therapies. In recent decades, metallic nanoparticles (MNPs) and lipid nanoparticles (LNPs) have shown a specific impact ( > 84% Candida biofilm inhibition in pre-clinical models) by addressing the critical challenges of mitigating drug side effects and multidrug resistance (MDR).

Areas Covered: This paper provides an in-depth overview of synthesis, fabrication, mechanistic insights, preclinical and clinical practices for MNPs and LNPs, discussing and highlighting their therapeutic efficacy against resistant Candida species over traditional methods.

Respiratory diseases are among the main causes of morbidity and mortality worldwide, encompassing a wide array of illnesses. Among these diseases, including acute lung injury, chronic obstructive pulmonary disease (COPD), asthma, pulmonary fibrosis, obstructive sleep apnoea (OSA), and pathogenic infections, the immune system plays a significant role in whole-body pathophysiology. These occurrences have been recognised to affect the ocular system, bringing about the novel idea of the lung-eye axis with emerging literature highlighting the fundamental connection of exacerbation between systems.

Breast cancer remains the leading cause of cancer-related death worldwide, underscoring the urgent need for novel therapeutic strategies. Icariin, a prenylated flavonol glycoside derived from species, has emerged as a promising multi-targeted agent with potent anticancer activity. Preclinical studies demonstrate that icariin modulates key oncogenic pathways, including PI3K/Akt, MAPK, NF-κB/SIRT6, and AMPK/mTOR to inhibit tumor cell proliferation, induce apoptosis, and regulate autophagy.

Chronic obstructive pulmonary disease is a chronic lung disease which causes obstruction and inflammation in the airways or other parts of the lung. It is often associated with structural changes in the lung due to persistent inflammation caused by prolong exposure to cigarette smoke. Other factors such as oxidative stress, chronic inflammation and cellular senescence also play a major role in the progression of the disease.

This systematic review and meta-analysis were conducted to evaluate the therapeutic efficacy of Astragaloside IV (As-IV) in ischemic heart disease based on the preclinical evidence and to correlate the cardioprotective effect with various available mechanisms. This systematic review and meta-analysis were conducted based on the results of a thorough literature search in databases of published papers, such as PubMed, Embase, and Google Scholar. A total of 18 studies that met the inclusion/exclusion criteria were included.

Aims: To evaluate the analgesic and neuroprotective effects of cytidine, uridine, and gabapentin-administered alone and in combination-in models of diabetic neuropathy and formalin-induced acute and inflammatory pain.

Materials & Methods: Oral doses of cytidine, uridine, and gabapentin (100 mg/kg each) were administered to rats with streptozotocin-induced diabetic neuropathy and in a formalin test model. Behavioral responses were recorded at 30, 60, and 120 minutes following treatment after five weeks of diabetes induction.

Introduction: Non-small cell lung cancer (NSCLC) continues to pose a considerable health challenge with few therapeutic alternatives. Liquid crystalline nanoparticles (LCN) are nanostructured drug delivery systems made of lipid-based amphiphilic materials that self-assemble into crystalline phases in aqueous environments. LCN have become a promising way to treat NSCLC owing to their specific properties that make them useful for targeted delivery and controlled drug release.

Aging is an extremely significant risk associated with neurodegeneration. The most prevalent neurodegenerative disorders (NDs), such as Alzheimer's disease (AD) are distinguished by the prevalence of proteinopathy, aberrant glial cell activation, oxidative stress, neuroinflammation, defective autophagy, cellular senescence, mitochondrial dysfunction, epigenetic changes, neurogenesis suppression, increased blood-brain barrier permeability, and intestinal dysbiosis that is excessive for the patient's age. Substantial body studies have documented a close relationship between gut microbiota and AD, and restoring a healthy gut microbiota may reduce or even ameliorate AD symptoms and progression.

As a promising candidate for tackling drug-resistant cancers, triptolide, a diterpenoid derived from the Chinese medicinal plant Tripterygium wilfordii, has been developed. This review summarizes potential antitumor activities, including the suppression of RNA polymerase II, the suppression of heat shock proteins (HSP70 and HSP90), and the blockade of NF-kB signalling. Triptolide is the first known compound to target cancer cells specifically but spare normal cells, and it has success in treating cancers that are difficult to treat, including pancreatic, breast, and lung cancers.

Objectives: The concept of beauty from within is a growing trend in the market and people now look for oral supplements that can enhance the well-being of skin from within. Within this principle, a proprietary pomegranate extract (Grantria), standardized to ellagic acid, punicic acid and punicalagin, was developed using ADOP (Advanced Oil-Powder) technology and was clinically evaluated for its efficacy and safety in healthy adults.

Methods: This evaluation was carried out as a randomized, placebo-controlled clinical study for 60 days at a daily dose of 300 mg.

Corticosteroids are extensively used in medicine for their powerful anti-inflammatory and immunosuppressive effects. However, their psychiatric side effects-such as mood disturbances, anxiety, and psychosis-are significant yet often underappreciated. This review provides a comprehensive exploration of corticosteroid-induced psychiatric disorders, with a focus on their underlying mechanisms and clinical implications.

Background And Purpose: This study aimed to improve the stability and prolonged gefitinib release from the nanoliposomes.

Experimental Approach: Nanoliposomes were prepared by reverse-phase evaporation and optimized using Box-Behnken design to investigate the influence of sonication time ( ), tween 80 / soya phosphatidylcholine ratio ( ), and cholesterol/soya phosphatidylcholine ratio ( ) on nanoliposomes.

Key Results: Optimized nanoliposomes were quasi-spherical shaped, with a mean dimension of 93.

Chronic obstructive pulmonary disease (COPD) is strongly linked to cigarette smoke, which contains toxins that induce oxidative stress and airway inflammation, ultimately leading to premature airway epithelial cell senescence and exacerbating COPD progression. Current treatments for COPD are symptomatic and hampered by limited efficacy and severe side effects. This highlights the need to search for an optimal therapeutic candidate to address the root causes of these conditions.

Inhalation of particulate matter (PM), one of the many components of air pollution, is associated with the development and exacerbation of chronic respiratory diseases, such as chronic obstructive pulmonary disease (COPD). COPD is one of the leading causes of global mortality and morbidity, with a paucity of therapeutic options and a significant contributor to global health expenditure. This review aims to provide a mechanistic understanding of the cellular and molecular pathways that lead to the development of COPD following chronic PM exposure.

Article Synopsis
  • - Parkinson's disease (PD) is characterized by misfolded α-synuclein (αSyn) proteins, leading to both motor symptoms (like stiffness and tremors) and nonmotor symptoms that can vary among individuals due to progressive neuron and synapse loss.
  • - While medical and surgical treatments, such as deep brain stimulation, can improve well-being and survival, they do not stop the disease from progressing.
  • - The complexity of the brain and the blood-brain barrier (BBB) make delivering drugs for PD treatment difficult, but this article explores the potential of chitosan-based drug delivery systems as a solution.
