Os nanog is s o nanosistemas n o i nicos e i nicos fabricados a partir de pol meros reticulados f sica ou quimicamente, hidrof licos, hidrof bicos ou anfif licos. Os materiais que formam o nanogel podem tamb m ser constitu dos por polissac ridos e prote nas, que s o selecionados com base na sua resposta biodegrad vel e menos imunog nica. Estes materiais s o especialmente bem sucedidos no aumento da carga do f rmaco na regi o visada e no controlo da propens o de todos os outros nanocarreadores para libertarem o bioativo carregado. Os NG com um di metro entre 1 e 1000 nm integram as propriedades dos hidrog is e dos nanomateriais. Um novo transportador de f rmacos deve ter duas carater sticas principais: deve transportar o f rmaco velocidade desejada e deve entregar com xito o medicamento no local-alvo. Consequentemente, os nanog is possuem v rias propriedades sofisticadas que podem ajudar no desenvolvimento de novos sistemas de administra o. Um nanogel definido como "um sistema semi-s lido que consiste numa dispers o constitu da por pequenas part culas inorg nicas ou grandes part culas org nicas contidas e interpenetradas por um l quido" pela Farmacopeia dos Estados Unidos.

The role of gut microbiota is crucial in maintaining human health. Several studies have claimed the role of gut microbiota in managing metabolic and mental disorders as well as diseases of the cardiovascular and autoimmune nervous system. In general, gut microbiota is involved in imparting specific functions in the host's drug and nutrient metabolism, protection against certain pathogens, maintaining the structural integrity of the gut mucosal membrane, and immunomodulation. They are generally divided into Bacteroidetes and Firmicutes. Gut microbiota influences many areas of human health from innate immunity to appetite and energy metabolism. Some of the studies have recently investigated the vital role of gut microbiota in cholesterol metabolism possibly through five different mechanisms; changing the ratio of free bile acids to conjugated bile acids; fermenting dietary fiber to produce short-chain fatty acids that can inhibit cholesterol synthesis; microbiota-mediated gene expression for cholesterol metabolism; converting cholesterol to low absorbing coprostanol; and Reducing blood cholesterol by inhibiting lipopolysaccharides.

The complicated chemical reactions involved in the production of the newer drug delivery systems have mainly impeded efforts to build successful targeted drug delivery systems for a prolonged duration of time. Nanosponges, a recently created colloidal system, have the potential to overcome issues with medication toxicity, decreased bioavailability, and drug release over a wide area because they can be modified to work with both hydrophilic and hydrophobic types of drugs. Nanosponges are small-sized with a three-dimensional network having a porous cavity. They can be prepared easily by crosslinking cyclodextrins with different compounds. Due to Cyclodextrin's outstanding biocompatibility, stability, and safety, many Cyclodextrin-based drug delivery systems have been developed promptly. The nanosponge drug delivery system possesses various applications in various ailments such as cancer, autoimmune diseases, theranostic applications, enhanced bioavailability, stability, etc. This review elaborates on benefits and drawbacks, preparation techniques, factors affecting their preparation, characterization techniques, applications, and most current developments in nanosponges.

Les nanogels sont des nanosyst mes non ioniques et ioniques constitu s de polym res r ticul s physiquement ou chimiquement, hydrophiles, hydrophobes ou amphiphiles. Les mat riaux formant les nanogels peuvent galement tre constitu s de polysaccharides et de prot ines, s lectionn s en fonction de leur biod gradabilit et de leur moindre immunog nicit . Ces nanogels sont particuli rement efficaces pour augmenter la charge utile du m dicament dans la r gion cibl e et pour contr ler la propension de tous les autres nanocarriers fuir le bioactif charg . Les GN d'un diam tre compris entre 1 et 1000 nm int grent les propri t s des hydrogels et des nanomat riaux. Un nouveau transporteur de m dicaments doit pr senter deux caract ristiques principales: il doit transporter le m dicament la vitesse souhait e et le d livrer avec succ s au site cible. Par cons quent, les nanogels poss dent plusieurs propri t s sophistiqu es qui peuvent contribuer au d veloppement de nouveaux syst mes d'administration. Un nanogel est d fini comme "un syst me semi-solide constitu d'une dispersion de petites particules inorganiques ou de grosses particules organiques contenues et interp n tr es par un liquide" par la pharmacop e des tats-Unis.

Nanogele sind nichtionische und ionische Nanosysteme, die aus physikalisch oder chemisch vernetzten Polymeren bestehen, die entweder hydrophil, hydrophob oder amphiphil sind. Die Nanogel-bildenden Materialien k nnen auch aus Polysacchariden und Proteinen bestehen, die aufgrund ihrer biologisch abbaubaren, weniger immunogenen Reaktion ausgew hlt werden. Diese sind besonders erfolgreich bei der Erh hung der Nutzlast des Arzneimittels in der Zielregion und der Kontrolle der Neigung aller anderen Nanotr ger, den geladenen bioaktiven Stoff auslaufen zu lassen. NGs mit einem Durchmesser zwischen 1 und 1000 nm vereinen die Eigenschaften von Hydrogelen und Nanomaterialien. Ein neuartiger Wirkstofftransporter sollte zwei Hauptmerkmale aufweisen: Er sollte den Wirkstoff mit der gew nschten Geschwindigkeit transportieren und das Medikament erfolgreich an den Zielort bringen. Daher besitzen Nanogele mehrere anspruchsvolle Eigenschaften, die bei der Entwicklung neuer Verabreichungssysteme hilfreich sein k nnen. Ein Nanogel wird in der United States Pharmacopoeia definiert als "ein halbfestes System, das aus einer Dispersion besteht, die entweder aus kleinen anorganischen Partikeln oder gro en organischen Partikeln besteht, die in einer Fl ssigkeit enthalten und von dieser durchdrungen sind".

I nanogel sono nanosistemi non ionici e ionici costituiti da polimeri reticolati fisicamente o chimicamente, idrofili, idrofobici o anfifilici. I materiali che formano i nanogel possono essere costituiti anche da polisaccaridi e proteine, selezionati in base alla loro risposta biodegradabile e meno immunogena. Questi materiali sono particolarmente efficaci nell'aumentare il carico di farmaco nella regione mirata e nel controllare la propensione di tutti gli altri nanocarrier a perdere il bioattivo caricato. I GN con un diametro compreso tra 1 e 1000 nm integrano le propriet degli idrogel e dei nanomateriali. Un nuovo trasportatore di farmaci deve avere due caratteristiche principali: deve trasportare il farmaco alla velocit desiderata e deve consegnare con successo il farmaco al sito bersaglio. Di conseguenza, i nanogel possiedono diverse propriet sofisticate che possono contribuire allo sviluppo di nuovi sistemi di somministrazione. La Farmacopea degli Stati Uniti definisce un nanogel come "un sistema semisolido costituito da una dispersione di piccole particelle inorganiche o di grandi particelle organiche contenute e compenetrate da un liquido".

Nanogels are non-ionic and ionic nanosystems that are made from physically or chemically cross-linked polymers, either hydrophilic, hydrophobic, or amphiphilic. The nanogel-forming materials may also consist of polysaccharides and proteins, which are selected based on their biodegradable, less immunogenic response. These are made to be particularly successful in increasing the drug payload in the targeted region and controlling the propensity of all the other nanocarriers to leak the loaded bioactive. NGs with a diameter ranging between 1 and 1000 nm integrate the properties of hydrogels and nanomaterials. A novel drug transporter ought to have two primary characteristics: it should carry the drug at the desired rate and it should successfully deliver the medication to the target site. As a result, nanogels possess several sophisticated properties that can aid in the development of new delivery systems. A nanogel is defined as "a semisolid system consisting of a dispersion made up of either small inorganic particles or big organic particles contained and interpenetrated by liquid" by the United States Pharmacopoeia.

Medicinal plants have long been prized for their ability to support memory and brain health and provide an alternative to medications. From ancient civilizations to modern science, numerous medicinal plants are known for their neuroprotective and cognitive properties. Ginkgo biloba is obtained from one of the oldest living trees and forms the basis of traditional medicine. The flavonoids and terpenes it contains are known to improve cognitive function and memory by improving blood flow to the brain. Bacopa Monnieri is a well-known herb in Ayurvedic medicine, known for its ability to improve memory and learning abilities. The active compound, bacoside, is thought to support synaptic communication and protect neurons from oxidative stress. Rhodiola rosea, another plant highly regarded in Scandinavian and Chinese medicine, is known for its adaptogenic properties. Rhodiola rosea is known to be effective in supporting overall brain function by regulating the stress response, reducing mental fatigue, and improving cognitive function.
