Oral delivery of dihydroartemisinin for the treatment of melanoma via bovine milk exosomes.

Cancer, particularly skin cancer, is a major cause of mortality worldwide, with melanoma being one of the most aggressive and challenging to treat types. Current therapeutic options, such as dacarbazine (DTIC), have limitations due to dose-related toxicities like liver toxicity. Therefore, there is a need for new and effective treatments for melanoma.

An Investigation of In Vitro Anti-Cancer Efficacy of Dihydroartemisinin-Loaded Bovine Milk Exosomes Against Triple-Negative Breast Cancer.

Impact of the Drug Loading Method on the Drug Distribution and Biological Efficacy of Exosomes.

Exosomes are biological nanovesicles that are intrinsically loaded with thousands of biomacromolecules and are principally responsible for cell-to-cell communication. Inspired by the natural payload, they have been extensively investigated as drug delivery vehicles; however, the drug distribution, whether into or onto exosomes, is still debatable. In the present work, we have tried to investigate it systemically by selecting 5-fluorouracil (5-FU) (hydrophilic) and paclitaxel (PAC) (hydrophobic), drugs with very different physicochemical characteristics, for the loading to the exosomes.

A Bacteriophage-Loaded Microparticle Laden Topical Gel for the Treatment of Multidrug-Resistant Biofilm-Mediated Burn Wound Infection.

Klebsiella pneumoniae is regarded as one of the most profound bacteria isolated from the debilitating injuries caused by burn wounds. In addition, the multidrug resistance (MDR) and biofilm formation make treating burn patients with clinically available antibiotics difficult. Bacteriophage therapy has been proven an effective alternative against biofilm-mediated wound infections caused by MDR bacterial strains.

A Bacteriophage Microgel Effectively Treats the Multidrug-Resistant Bacterial Infections in Burn Wounds.

Multidrug-resistant (MDR) () is one of the major pathogens present in burn wound infections. Biofilm formation makes it further challenging to treat with clinically available antibiotics. In the current work, we isolated the -specific bacteriophages (BPABΦ1), loaded into the chitosan microparticles followed by dispersion in gel, and evaluated therapeutic efficacy against MDR clinical strains.

Quality-by-design-based development of ultradeformable nanovesicular transgelosome of standardized extract for melanoma.

Melanoma is the most aggressive and deadly form of skin cancer. The stratum corneum of the skin is a major obstacle to dermal and transdermal drug delivery. Ultradeformable nanovesicular transferosome has the capacity for deeper skin penetration and its incorporation into hydrogel forms a transgelosome that has better skin permeability and patient compliance.

Quality by design-based development and optimization of fourth-generation ternary solid dispersion of standardized Piper longum extract for melanoma therapy.

The study aimed to enhance the solubility, dissolution, and oral bioavailability of standardized Piper longum fruits ethanolic extract (PLFEE) via fourth-generation ternary solid dispersion (SD) for melanoma therapy. With the use of solvent evaporation method, the standardized PLFEE was formulated into SD, optimized using Box-Wilson's central composite design (CCD), and evaluated for pharmaceutical performance and in vivo anticancer activity against melanoma (B16F10)-bearing C57BL/6 mice. The optimized SD showed good accelerated stability, high yield, drug content, and content uniformity for bioactive marker piperine (PIP).

Endorsement of TNBC Biomarkers in Precision Therapy by Nanotechnology.

Breast cancer is a heterogeneous disease which accounts globally for approximately 1 million new cases annually, wherein more than 200,000 of these cases turn out to be cases of triple-negative breast cancer (TNBC). TNBC is an aggressive and rare breast cancer subtype that accounts for 10-15% of all breast cancer cases. Chemotherapy remains the only therapy regimen against TNBC.

Piperine loaded metal organic frameworks reverse doxorubicin induced chemobrain in adult zebrafish.

The study's primary goal was to enhance medicinal potential of piperine (PIP)-loaded zeolitic imidazolate frameworks-8 (PIP@ZIF-8) against doxorubicin (DOX)-induced cognitive impairments in zebrafish. Herein, PIP@ZIF-8 was synthesized via easy, economical and reproducible ultrasonication method followed by spray drying technology. ZIF-8's structural integrity has been confirmed by PXRD, and even after PIP was encapsulated, the structure of ZIF-8 remained unchanged.

Combination Therapy Comprising Paclitaxel and 5-Fluorouracil by Using Folic Acid Functionalized Bovine Milk Exosomes Improves the Therapeutic Efficacy against Breast Cancer.

Paclitaxel (PAC) has been approved by FDA for clinical use (Taxol), yet dose-dependent severe toxicity due to the adjuvant Cremophor EL in combination with ethanol is a major drawback. The drawbacks of the current therapy can be overcome by (i) finding a suitable vehicle that cannot only bypass the above adjuvant but also be used to deliver drugs orally and (ii) combining the PAC with some other chemotherapeutics to have the enhanced therapeutic efficacy. In the current work, we have used folic acid (FA) functionalized bovine milk-derived exosomes for oral delivery of PAC in combination with 5-fluorouracil (5-FU).

Onychomycosis is the most common fungal infection of the nail affecting the skin under the fingertips and the toes. Currently, available therapy for onychomycosis includes oral and topical therapies, either alone or in combination. Oral antifungal medication has been associated with poor drug bioavailability and potential gastrointestinal and systemic side effects.

Emergence of Nanotechnology as a Powerful Cavalry against Triple-Negative Breast Cancer (TNBC).

Triple-negative breast cancer (TNBC) is considered one of the un-manageable types of breast cancer, involving devoid of estrogen, progesterone, and human epidermal growth factor receptor 2 (HER 2) receptors. Due to their ability of recurrence and metastasis, the management of TNBC remains a mainstay challenge, despite the advancements in cancer therapies. Conventional chemotherapy remains the only treatment regimen against TNBC and suffers several limitations such as low bioavailability, systemic toxicity, less targetability, and multi-drug resistance.

Use of Synchrotron Phase-Sensitive Imaging for the Investigation of Magnetopriming and Solar UV-Exclusion Impact on Soybean () Leaves.

The combined response of exclusion of solar ultraviolet radiation (UV-A+B and UV-B) and static magnetic field (SMF) pre-treatment of 200 mT for 1 h were studied on soybean () leaves using synchrotron imaging. The seeds of soybean with and without SMF pre-treatment were sown in nursery bags kept in iron meshes where UV-A+B (280-400 nm) and UV-B (280-315 nm) from solar radiation were filtered through a polyester filters. Two controls were planned, one with polythene filter controls (FC)- which allows all the UV (280-400 nm); the other control had no filter used (open control-OC).
