    This review presents a synthesis of recent findings on the process through which cellular senescence (CS) facilitates Alzheimer’s disease (AD) development, along with an evaluation of the potential therapeutic benefits of eliminating senescent cells in AD treatment.

    A collection of diseases, termed channelopathies, originate from either a reduction in ion channel cell surface expression or the failure of these ion channels to function properly. To effectively manage the underlying cause, the delivery and incorporation of a functional ion channel into the membrane of the target cell is required. Regretfully, for the majority of channelopathies, current treatments are mainly aimed at relieving symptoms, while treatments that mend the underlying cellular damage are still a significant challenge. This context necessitates the use of gene and protein therapies as approaches. A functional protein’s expression via gene therapy hinges on the diseased cell’s machinery correctly folding and transporting the protein to its membrane. Functional protein delivery via protein therapy is contingent upon a purification process that maintains protein integrity, and the availability of an appropriate delivery vehicle for targeted administration. Within this review, we examine channelopathies and the currently available symptomatic treatments. Gene therapy, predominantly relying on viral vectors, is examined, followed by an analysis of the function of nanomedicine in protein therapy, and how it can be employed to deliver functional ion channels to diseased cells.

    Coronary artery disease (CAD) tragically holds the title of leading cause of morbidity and mortality in Western societies, despite progress in primary and secondary prevention strategies. Therefore, a variety of novel biomarkers have been pinpointed as potential diagnostic and therapeutic focal points, which could potentially improve patient outcomes, even if traditional risk factors are well-controlled. Lipoprotein (a) [Lp(a)], with its pro-atherogenic, pro-thrombotic, and pro-inflammatory effects, maintains relatively consistent levels that are significantly influenced by genetic programming. Epidemiological studies consistently indicate a relationship between elevated Lp(a) levels and an increased chance of developing acute coronary syndromes (ACS), even after adjusting for other established risk factors for coronary artery disease in multivariable analyses. Prior to the recent development of targeted therapies, Lp(a) remained without effective treatment options. As a result, Lp(a) is presently evaluated as a risk and treatment-modifying biomarker, with existing guidelines urging intensified LDL treatment in high-risk patients with elevated Lp(a) levels. Current advancements in Lp(a) treatment now include antisense oligonucleotides and small interfering RNAs, resulting in a substantial decrease in Lp(a) concentrations. The results from the ongoing phase-3 trials will furnish the necessary information to determine if Lp(a) will be designated as a biomarker for specific treatment to reduce cardiovascular mortality rates. Examining current evidence regarding Lp(a) as a biomarker linked to increased coronary artery disease (CAD) risk, this review also addresses the future potential of pharmaceutical interventions for reducing Lp(a) in high-risk patients.

    This research sought to gauge the diagnostic value of circulating neurofilament light chain (NFL) levels in differentiating among distinct types of dementia.

    Previous research exhibited inconsistent blood NFL modifications in various dementia types, including Alzheimer’s (AD), frontotemporal (FTD), Parkinson’s (PDD), Creutzfeldt-Jakob (CJD), and Lewy body (LBD) dementia.

    To consolidate the findings of studies examining the diagnostic accuracy of circulating NFL levels in various forms of dementia, a meta-analysis was executed to reinforce the evidentiary basis.

    PubMed, Web of Science, EMBASE, Medline, and Google Scholar were systematically searched for studies predating July 2022 that explored the correlation between blood NFL levels and dementia. STATA 120 software was utilized to derive the calculated outcomes.

    Serum and plasma NFL levels were significantly higher in AD patients than in healthy controls, with a standard mean difference (SMD) of 109 (95% confidence interval (CI): 0.48-1.70), I2 = 974%, and a p-value less than 0.0001. Patients with AD showing higher neurofilament light chain (NFL) levels in serum and plasma demonstrated a corresponding reduction in cerebrospinal fluid (CSF) A1-42, an increase in CSF total tau (t-tau) and phosphorylated tau (p-tau), lower Mini-Mental State Examination (MMSE) scores, and a decline in memory performance. Mild cognitive impairment (MCI) exhibited elevated neurofilament light chain (NFL) concentrations in blood serum and plasma compared to healthy controls (HC), a finding supported by statistically significant results (SMD = 0.53, 95% CI 0.18, 0.87, I² = 93.8%, p < 0.0001). No considerable correlation was noted between serum and plasma NFL levels and memory or visuospatial function in individuals with MCI. No statistically significant difference was found between preclinical AD and healthy control groups (HC), exhibiting a standardized mean difference (SMD) of 0.18, a 95% confidence interval from -0.10 to 0.47, an I² of 00%, and a p-value of 0.438. FTD patients displayed a noteworthy increase in serum and plasma NFL levels, significantly exceeding those observed in healthy controls (SMD = 108, 95% CI 072, 143, I2 = 833%, p < 0001). Individuals with frontotemporal dementia demonstrated a connection between elevated NFL levels in their blood (serum and plasma) and elevated NFL levels in their cerebrospinal fluid. In addition, the pooled parameters demonstrated the following: sensitivity was 0.82 (95% confidence interval 0.72 to 0.90), and specificity was 0.91 (95% confidence interval 0.83 to 0.96). A comparison of CJD patients to healthy controls (HC) revealed elevated NFL levels in both serum and plasma samples. Serum and plasma NFL levels exhibited no notable disparity between AD and FTD groups (SMD = -0.003, 95% CI -0.77 to 0.72, I² = 833%, p = 0.003).

    The study, in its conclusion, revealed abnormal blood NFL levels in AD and MCI, but not in subjects with preclinical AD. A study revealed abnormal NFL levels in the blood of individuals with FTD and CJD.

    The study’s overall conclusion was that unusual blood NFL levels were detected in AD and MCI, but not in preclinical AD stages. Blood NFL levels displayed abnormalities in patients with FTD and CJD.

    An autoimmune dermatological ailment, psoriasis, is noted for its recurrent episodes. This autoimmune skin condition, a prevalent issue, impacts 2-3% of individuals globally. This current review strives to examine and assess the effectiveness of established and cutting-edge nanotechnological strategies in alleviating psoriasis, and to discuss potential future directions. A meticulous search across diverse electronic databases, like ScienceDirect, Scopus, Google Scholar, ClinicalTrials.gov, Google Patents, ResearchGate, and PubMed, was undertaken to collect all the data presented in this review paper about psoriasis management employing anti-psoriatic agents and nanotechnology. An examination was conducted into the meaning of terms like topical, liposomes, niosomes, micro-needles, clinical trials, patents, pathogenesis, biosimilars, cytokines, and relevant associated words. Nano-technological advancements are seeing increased use because they allow for precise delivery, prompt onset, and a limited reach into the body’s systems. To address psoriatic conditions, researchers have examined innovative, secure, and efficient alternative therapeutic approaches. In addition, the possible function of numerous conventional treatments for psoriasis has been thoroughly studied. Well-explored are the patents, either finalized or under development, addressing psoriasis through topical means. Pharmaceutical advancements driven by nanotechnology have led to the development of formulations with improved physical, chemical, pharmacokinetic, and pharmacodynamic properties. Extensive research notwithstanding, a complete resolution to psoriasis continues to be problematic. Through a comprehensive analysis of the available literature, it can be inferred that innovative nanoparticle-based delivery methods hold the possibility of enhancing pharmacological effectiveness and resolving, or eliminating, issues connected to this ailment. A thorough review of the various drug delivery systems for treating psoriasis, including the different stages of clinical trials, patent status, therapeutic molecule commercialization, and future research prospects, has been undertaken.

    Developing countries and the Asian-Pacific region are significantly challenged by HFMD, a noticeable disease mostly afflicting children younger than five. A common cause of this disease is the synergistic action of enterovirus 71 (EV71) and Coxsackievirus A16. HFMD, a mild form of fever and general sickness, often lasts for approximately 10 days. Some risk factors comprise a young age, male gender, poor hygiene practices, and substantial social connections. A clinical diagnosis of hand, foot, and mouth disease (HFMD) is possible by isolating the virus from the stool and pharynx, and confirming it using light microscopy. To confirm viral presence in swabbed lesions, the Polymerase Chain Reaction Assay stands as the gold standard. Late confirmation of the arrangement could produce significant issues. The treatment and vaccination of the different types of hand, foot, and mouth disease are not covered by licensed, widely available options. Implementing the eight guidelines set forth by the WHO is the principal approach to curbing and preventing this disease from spreading.
