Summary
Nanotechnology enhances photodynamic therapy (PDT) by improving photosensitizers like chlorins. Nanocarriers overcome PDT limitations, showing promise for cancer and antimicrobial treatments.
Area of Science:
- Biomedical Engineering
- Nanomedicine
- Photochemistry
Background:
- Photodynamic therapy (PDT) is a clinical treatment for cancer and infections.
- Current PDT faces challenges including poor photosensitizer solubility, limited light penetration, and tumor hypoxia.
- Chlorins are established photosensitizers with clinical relevance.
Purpose of the Study:
- To review advancements in using nanotechnology to enhance chlorin-based photodynamic therapy.
- To explore nanocarrier strategies for improving PDT efficacy and reducing side effects.
- To discuss applications in oncology and antimicrobial photodynamic therapy (aPDT).
Main Methods:
- Review of literature on nanocarrier systems for chlorin delivery.
- Analysis of various nanocarrier types: lipid-based, polymer-based, and carbon-based.
- Examination of in vitro and in vivo studies of nanocarrier-enhanced PDT and aPDT.
Main Results:
- Nanocarriers significantly improve chlorin properties like solubility and targeting.
- Various nanocarrier platforms (liposomes, micelles, graphene oxide, etc.) show potential.
- Nanocarrier-enhanced chlorins demonstrate efficacy in preclinical models for cancer and multidrug-resistant bacteria.
Conclusions:
- Nanotechnology offers effective solutions to overcome key limitations in photodynamic therapy.
- Nanocarrier-based chlorins hold significant promise for improved cancer treatment and combating antimicrobial resistance.
- Further clinical translation is needed to fully realize the potential of nanocarrier-enhanced PDT.

01:11Direct-Acting Cholinergic Agonists: Therapeutic Uses
Direct-acting cholinergic agonists have many therapeutic uses in various medical fields. Choline esters, including acetylcholine, have limited clinical utility due to their non-selectivity and short duration of action. Still, acetylcholine and carbachol are applied topically during ophthalmologic surgery to induce miosis. Pilocarpine, a muscarinic and ganglionic stimulator, effectively treats open-angle glaucoma and alleviates xerostomia and dry mouth caused by radiotherapy or Sjögren syndrome.
01:23Drugs Acting on Autonomic Ganglia: Stimulants
Ganglionic stimulants activate NM nicotinic receptors in autonomic ganglia, falling into two categories: nicotine mimetics [e.g., lobeline, dimethylpiperazine, tetramethylammonium] and muscarinic receptor agonists [e.g., muscarine, methacholine]. The first category's action is rapid and blocked by nicotinic receptor antagonists, while the second category's action is delayed and blocked by atropine-like agents. Nicotine, an alkaloid, affects the heart rate by stimulating sympathetic or...
01:30Adrenergic Agonists: Therapeutic Uses
Adrenergic agonists have diverse therapeutic uses across various medical conditions and emergencies.
Emergency and Intensive Care Unit (ICU) applications: Pressor agents increase blood pressure, heart rate, and contractility in shock and organ failure situations. Dopamine can induce vasodilation and stimulate adrenoceptors. Endogenous catecholamines are effective in treating cardiogenic shock. α2-agonists like clonidine can reverse anesthesia-induced hypertension.

01:31Skeletal Muscle Relaxants: Therapeutic Uses
Skeletal muscle relaxants are used to relax muscle tone and alleviate painful muscle contractions. However, the choice of skeletal muscle relaxants depends on the duration of the surgical procedure in order to minimize potential side effects. Skeletal muscle relaxants like neuromuscular blocking agents [NMBAs] are commonly employed as adjuvants alongside general anesthetics in clinical settings. NMBAs are also used to maintain controlled ventilation during surgery of the larynx or pharynx as...
01:24Centrally Acting Muscle Relaxants: Therapeutic Uses
Centrally acting muscle relaxants reduce muscle tone and tension by interfering with the postsynaptic reflexes in the central nervous system.
Centrally acting drugs are classified into spasmolytic and antispasmodic drugs. Spasmolytic drugs such as baclofen, diazepam, and tizanidine inhibit spinal motor neurons and decrease muscle tone. Spasmolytic drugs are administered for severe and chronic spasms due to multiple sclerosis, cerebral palsy, stroke, and spinal cord and muscle injuries. However,...

01:28Drugs Affecting GI Tract Motility: Dopamine Receptor Antagonists
Prokinetic agents are specialized medications that stimulate gastrointestinal (GI) motility, promoting food movement through the GI tract. Dopamine, an inhibitory neurotransmitter, plays a significant role in this process, reducing GI motility and indirectly controlling the speed of digestion. Dopamine receptor antagonists, such as metoclopramide and domperidone, offer a unique advantage as prokinetic agents. By blocking the dopamine receptors, these drugs increase GI motility, improving food...
