Polycaprolactone microparticles for the subcutaneous administration of cannabidiol: in vitro and in vivo release.

Cannabidiol (CBD) has become a highly attractive entity in therapeutics. However, its low aqueous solubility, instability and handling problems limit the development of effective CBD formulations. Subcutaneously administered CBD-loaded polycaprolactone microparticles (MP) represent an interesting strategy to overcome these challenges.

Biological evaluation of integrin αβ-targeted Ga-labeled HEVNPs in HCT 116 colorectal tumor-bearing mice.

Integrins are cell surface receptors involved in multiple functions vital for cellular proliferation. Various tumor cells overexpress αβ-integrins, making them ideal biomarkers for diagnostic imaging and tumor-targeted drug delivery. LXY30 is a peptide that can specifically recognize and interact with the integrin αβ, a molecule overexpressed in breast, ovarian and colorectal cancer.

Functionalization of Morin-Loaded PLGA Nanoparticles with Phenylalanine Dipeptide Targeting the Brain.

Alzheimer's disease (AD) is the most prevalent neurodegenerative disorder, with its incidence constantly increasing. To date, there is no cure for the disease, with a need for new and effective treatments. Morin hydrate (MH) is a naturally occurring flavonoid of the family with antioxidant and anti-inflammatory properties; however, the blood-brain barrier (BBB) prevents this flavonoid from reaching the CNS when aiming to potentially treat AD.

DoE-based development of celecoxib loaded PLGA nanoparticles: In ovo assessment of its antiangiogenic effect.

Abnormal angiogenesis plays a main role in the pathogenesis of many diseases such as cancer, and inflammatory autoimmune disorders among others, and its inhibition represents a potential strategy for their management. Celecoxib (CXB) that is one of the most prescribed selective COX-2 inhibitors and is currently approved for the treatment of osteoarthritis, rheumatoid arthritis, and ankylosing spondylitis inhibits angiogenesis. The objective of this manuscript was to design, develop, and characterize polymeric nanoparticles for the parenteral administration of CXB which the aim of facilitating its administration and improving its antiangiogenic activity while decreasing its adverse effects.

Synthesis and ex vivo biodistribution of two Ga-labeled tetrazine tracers: Comparison of pharmacokinetics.

Pretargeted PET imaging allows the use of radiotracers labeled with short-living PET radionuclides for tracing drugs with slow pharmacokinetics. Recently, especially methods based on bioorthogonal chemistry have been under intensive investigation for pretargeted PET imaging. The pharmacokinetics of the radiotracer is one of the factors that determine the success of the pretargeted strategy.

Actively Targeted Nanomedicines in Breast Cancer: From Pre-Clinal Investigation to Clinic.

Breast cancer is one of the most frequently diagnosed tumors and the second leading cause of cancer death in women worldwide. The use of nanosystems specifically targeted to tumor cells (active targeting) can be an excellent therapeutic tool to improve and optimize current chemotherapy for this type of neoplasm, since they make it possible to reduce the toxicity and, in some cases, increase the efficacy of antineoplastic drugs. Currently, there are 14 nanomedicines that have reached the clinic for the treatment of breast cancer, 4 of which are already approved (Kadcyla, Enhertu, Trodelvy, and Abraxane).

The tale of microencapsulated rifampicin: is it useful for the treatment of periprosthetic joint infection?

Purpose: Microencapsulation techniques have allowed the addition of rifampicin to bone cement, but its in vivo efficacy has not been proven. The aim of our study is to determine the superiority of cement containing gentamicin and rifampicin microcapsules in the treatment of PJI versus cement exclusively containing gentamicin.

Methods: An S.

Matrix tablets based on a novel poly (magnesium acrylate) hydrogel for the treatment of inflammatory bowel diseases.

The objective of this work was to evaluate the potential use of a new polymer (PAMgA) in the development sustained release matrix tablets for the treatment of bowel inflammatory diseases. For this purpose, budesonide, a highly lipophilic compound, was used as model drug. Tablets with two reticulation grades of PAMgA (PAMgA 5 and 40) and with 9 mg of budesonide were developed and characterized.

Breast cancer is the most frequent neoplasm in the female population [...

Perspectives in Breast and Ovarian Cancer Chemotherapy by Nanomedicine Approach: Nanoformulations in Clinical Research.

Background: Breast and ovarian carcinomas represent major health problems in women worldwide. Chemotherapy constitutes the main treatment strategy, and the use of nanocarriers, a good tool to improve it. Several nanoformulations have already been approved, and others are under clinical trials for the treatment of both types of cancers.

Medical Use of Cannabinoids.

Cannabinoid receptors, endocannabinoids and the enzymes responsible for their biosynthesis and degradation constitute the endocannabinoid system. In recent decades, the endocannabinoid system has attracted considerable interest as a potential therapeutic target in numerous pathological conditions. Its involvement in several physiological processes is well known, such as in energy balance, appetite stimulation, blood pressure, pain modulation, embryogenesis, nausea and vomiting control, memory, learning and immune response, among others, as well as in pathological conditions where it exerts a protective role in the development of certain disorders.

Effects of cannabidiol plus naltrexone on motivation and ethanol consumption.

Background And Purpose: The aim of this study was to explore if the administration of naltrexone together with cannabidiol (CBD) may improve the efficacy in reducing alcohol consumption and motivation rather than any of the drugs given separately.

Experimental Approach: The effects of low doses of naltrexone (0.7 mg·kg , p.

Insights into the effects of the endocannabinoid system in cancer: a review.

In the last few decades, the endocannabinoid system has attracted a great deal of interest in terms of its applications to clinical medicine. In particular, its applications in cancer probably represent one of the therapeutic areas with most promise. On the one hand, expression of the endocannabinoid system is altered in numerous types of tumours, compared to healthy tissue, and this aberrant expression has been related to cancer prognosis and disease outcome, suggesting a role of this system in tumour growth and progression that depends on cancer type.
