Abstract Amyloid beta‐protein (AβA β ) is a main hallmark of Alzheimer's disease (AD), and low amount Aβ protein accumulation appears to be potential marker for AD. Here, an electrochemical DNA biosensor based on polyamide/polyaniline carbon nanotubes (PA/PANI‐CNTs) developed with the aim diagnosing AD early using simple, low‐cost, accessible method rapidly detect Aβ42 in human blood. Electrospun PA nanofibers served as skeleton successive situ deposition PANI CNTs, which contribute both high conductivity abundant binding sites aptamers. After aptamers are immobilized, this aptasensor exhibits precise specific detection blood within only 4 min extremely fast response rate, lower limit, excellent linear range. These findings make significant contribution advancing development serum‐based techniques Aβ42, thereby paving way improved diagnostic capabilities field

Vaccines are one of the most effective medical interventions to combat newly emerging and re-emerging diseases. Prophylactic vaccines against rabies, measles, etc., have excellent effectiveness in preventing viral infection associated However, host immune response is unable inhibit virus replication or eradicate established diseases infected people. Therapeutic vaccines, expressing specific endogenous exogenous antigens, mainly induce boost cell-mediated immunity via provoking cytotoxic T cells elicit humoral activating B produce antibodies. The ultimate aim a therapeutic vaccine reshape for eradicating disease establishing lasting memory. Therefore, been developed treatment some infectious chronic noncommunicable Various technological strategies implemented development including molecular-based (peptide/protein, DNA mRNA vaccines), vector-based (bacterial vector yeast-based vaccines) cell-based (dendritic cell genetically modified as well combinatorial approaches. This review summarizes vaccine-induced describes status multiple types diseases, such those caused by HPV, HBV, HIV, HCV, SARS-CoV-2, cancer, hypertension, Alzheimer's disease, amyotrophic lateral sclerosis, diabetes, dyslipidemia, that evaluated recent preclinical clinical studies.

Abstract Protein amyloid aggregation has been widely observed to occur and plays important roles in both physiological processes pathological diseases. Remarkably, aggregates assembled by native proteins gain a variety of different biological activities, which cannot be adopted the unassembled protein alone. Thus, it is investigate molecular basis self‐assembly how aggregated structure determines its function. In review, we firstly introduce our structural knowledge on undergo conformational transition assemble into aggregate, with main focus fibril, major species aggregate. Then, elaborate structures fibrils enable them fulfill highly diverse functions either or condition. Furthermore, discuss polymorph very unique feature implication understanding structure‐function relationship fibrils. Finally, point out importance applying integrating new approaches for deepening study highlight potential designing fibril‐based functional bio‐nanomaterials application.

Early cognitive decline in patients with Alzheimer's (AD) is associated quantifiable structural and functional connectivity changes the brain. AD dysregulation of Aβ tau metabolism progressively disrupt normal synaptic function, leading to loss synapses, decreased hippocampal density early atrophy. Advances brain imaging techniques living have enabled transition from clinical signs symptoms-based diagnosis biomarkers-based diagnosis, techniques, quantitative EEG, body fluids sampling. The hippocampus has a central role semantic episodic memory processing. This function critically dependent on intrahippocampal connections many cortical regions, including perirhinal entorhinal cortex, parahippocampal association regions temporal parietal lobes, prefrontal cortex. Therefore, reflected altered intrinsic networks (aka large-scale networks), memory, default mode, salience networks. narrative review discusses recent critical issues related detecting AD-associated markers high-risk or neuropsychologically diagnosed subjective impairment mild impairment.
