Enhancing targeted delivery and efficacy of PEGylated liposomal doxorubicin with liposomal minoxidil: comprehensive in silico, in vitro, and in vivo tumor model studies.

The therapeutic efficacy of nanoparticle (NP)-encapsulated cytotoxic drugs has remained limited by poor penetration into solid tumors. To address this challenge, we developed a novel strategy using minoxidil-loaded nanoliposomes (Lip-MXD) to induce tumor vasodilation and enhance the delivery of PEGylated liposomal doxorubicin (PLD). We developed a remote loading method utilizing a calcium acetate gradient to encapsulate MXD into liposomes, achieving a high MXD encapsulation efficiency (87%).

Angiopoietin-like protein inhibitors: Promising agents for the treatment of familial hypercholesterolemia and atherogenic dyslipidemia.

Background And Aims: This review examines the physiological functions of Angiopoietin-like proteins (ANGPTLs) in lipid metabolism and the epidemiology of atherosclerotic cardiovascular disease (ASCVD), while discussing their potential as therapies for dyslipidemias.

Methods: A review of contemporary literature on ANGPTLs was conducted.

Results: ANGPTLs comprise eight secreted proteins that share structural similarities with the angiopoietin family and serve as key regulators of various physiological and biochemical functions.

Ultrasound-assisted efficient targeting of doxorubicin to the tumor microenvironment by lyso-thermosensitive liposomes of varying phase transition temperatures.

Premature drug release is the primary hindrance to the effective function of the lyso-thermosensitive liposomes (LTSLs) of doxorubicin (Dox), known as ThermoDox® for the treatment of cancer. Herein, we have optimized LTSLs by using a combination of phospholipids (PLs) with high transition temperatures (Tm) to improve the therapeutic outcome in an assisted ultrasound approach. For this, several Dox LTSLs were prepared using the remote loading method at varying molar ratios (0 to 90 %) of DPPC (Tm 41 °C) and HSPC (Tm 54.

Polymeric micelles paving the Way: Recent breakthroughs in camptothecin delivery for enhanced chemotherapy.

Camptothecin, a natural alkaloid, was first isolated from the bark and stem of the Camptotheca acuminate tree in China. It, along with its analogs, has demonstrated potent anti-cancer activity in preclinical studies, particularly against solid tumors such as lung, breast, ovarian, and colon cancer. Despite its promising anti-cancer activity, the application of camptothecin is limited due to its poor solubility, toxicity, and limited biodistribution.

Antimicrobial and anti-biofilm activities of bio-inspired nanomaterials for wound healing applications.

Chronic wounds are ubiquitously inhabited by bacteria, and they remain a challenge as they cause significant discomfort and because their treatment consumes huge clinical resources. To reduce the burden that chronic wounds place upon both patients and health services, a wide variety of approaches have been devised and investigated. Bioinspired nanomaterials have shown great success in wound healing when compared to existing approaches, showing better ability to mimic natural extracellular matrix (ECM) components and thus to promote cell adhesion, proliferation, and differentiation.

Role of exosomes in tumour growth, chemoresistance and immunity: state-of-the-art.

Cancer is one of the most lethal diseases, and limited available treatment options contribute to its high mortality rate. Exosomes are considered membrane-bound nanovesicles that include different molecules such as lipids, proteins, and nucleic acids. Virtually most cells could release exosomes exocytosis in physiological and pathological conditions.

Aptamer-conjugated carbon-based nanomaterials for cancer and bacteria theranostics: A review.

Aptamers are single-stranded oligonucleotides that link to various substrates with great affinity and selectivity, including small molecules, peptides, proteins, cells, and tissues. For this reason, they can be used as imaging agents for cancer imaging techniques. Multifunctional nanomaterials combined with imaging probes and drugs are promising cancer diagnosis and treatment candidates.

Guar (Cyamopsis tetragonoloba L.) plant gum: From biological applications to advanced nanomedicine.

Natural polymers are an efficient class of eco-friendly and biodegradable polymers, because they are readily available, come from natural sources, inexpensive and can be chemically modified with the correct reagents. Guar gum (GG) is a natural polymer with great potential to be used in pharmaceutical formulations due to its unique composition and lack of toxicity. GG can be designed to suit the needs of the biological and medical engineering sectors.

Nanotechnology in Bladder Cancer: Diagnosis and Treatment.

Bladder cancer (BC) is the second most common cancer of the urinary tract in men and the fourth most common cancer in women, and its incidence rises with age. There are many conventional methods for diagnosis and treatment of BC. There are some current biomarkers and clinical tests for the diagnosis and treatment of BC.

Nanomaterials for the Diagnosis and Treatment of Inflammatory Arthritis.

Nanomaterials have received increasing attention due to their unique chemical and physical properties for the treatment of rheumatoid arthritis (RA), the most common complex multifactorial joint-associated autoimmune inflammatory disorder. RA is characterized by an inflammation of the synovium with increased production of proinflammatory cytokines (IL-1, IL-6, IL-8, and IL-10) and by the destruction of the articular cartilage and bone, and it is associated with the development of cardiovascular disorders such as heart attack and stroke. While a number of imaging tools allow for the monitoring and diagnosis of inflammatory arthritis, and despite ongoing work to enhance their sensitivity and precision, the proper assessment of RA remains difficult particularly in the early stages of the disease.
