Encapsulation of Flucytosine into nanoliposomes for enhanced antifungal activity against Candida glabrata and Candida albicans.

Flucytosine (FC) is currently used as an antifungal drug for the treatment of infectious diseases. However, due to the development of drug resistance, the monotherapy of FC is limited. Recently, nanoliposomes have been studied as promising approaches to overcome microbial resistance.

Notch Signaling Suppression by Golden Phytochemicals: Potential for Cancer Therapy.

Cancer is one of the main causes of mortality worldwide. Cancer cells are characterized by unregulated cellular processes, including proliferation, progression, and angiogenesis. The occurrence of these processes is due to the dysregulation of various signaling pathways such as NF-κB (nuclear factor-κB), Wnt/beta-catenin, Notch signaling and MAPK (mitogen-activated protein kinases).

Utilizing a graphene quantum dot/hydrogel nanocomposite for determination of cisplatin in urine samples.

Currently, the growth and development of cancer are rising in the world, and as a result, the use of anticancer drugs such as cisplatin has also increased. Considering that the therapeutic index of anticancer drugs is low, it is essential to design and develop an accurate and correct method to analyze and determine the concentration of anticancer drugs in the biological samples. In this study, graphene quantum dots/hydrogel nanocomposite was used to determine cisplatin concentration in urine samples.

COVID -19: From the Molecular Mechanisms to Treatment.

The 2019 novel coronavirus (SARS-CoV-2) causes severe pneumonia called COVID-19 and leads to severe acute respiratory syndrome with a high mortality rate. The SARS-CoV-2 virus in the human body leads to jumpstarting immune reactions and multi-organ inflammation, which has poorer outcomes in the presence of predisposing conditions, including hypertension, dyslipidemia, dysglycemia, abnormal adiposity, and even endothelial dysfunction via biomolecular mechanisms. In addition, leucopenia, hypoxemia, and high levels of both cytokines and chemokines in the acute phase of this disease, as well as some abnormalities in chest CT images, were reported in most patients.

Analysis and identification of drug similarity through drug side effects and indications data.

Background: The measurement of drug similarity has many potential applications for assessing drug therapy similarity, patient similarity, and the success of treatment modalities. To date, a family of computational methods has been employed to predict drug-drug similarity. Here, we announce a computational method for measuring drug-drug similarity based on drug indications and side effects.

Applications of Exhaled Breath Condensate Analysis for Drug Monitoring and Bioequivalence Study of Inhaled Drugs.

The exhaled breath condensate (EBC) presents a simple and non-invasive alternative approach for bioequivalence assessments and therapeutic drug monitoring of inhaled drugs. EBC better represents the drug at the site of action and eliminates the possibility of the contribution of a swallowed portion of the dose when systemic bioavailability is used for assessment. This review summarizes the recently reported analytical methods for the quantification of drugs in EBC.

Review of Pharmaceutical Applications of Diethylene Glycol Monoethyl Ether.

Diethylene glycol monoethyl ether (DEGME) is a hydroalcoholic solvent that gained tremendous attention in the cosmetics, food, nanoformulations, and pharmaceutical industries. Due to its physicochemical features, it has been widely used as a penetration enhancer, surfactant, and solubilizer. Among numerous tradenames defined for DEGME -- Carbitol® (by Dow Chemical Co.

Cell homing strategy as a promising approach to the vitality of pulp-dentin complexes in endodontic therapy: focus on potential biomaterials.

Introduction: Over the last two decades, an increasing body of research suggests that well-designed biomaterials can attract resident stem cells to injured areas and control their behaviors and activities to encourage tissue regeneration. Fabricated biomaterials can enhance cell recruitment, multiplication, and transformation while also acting as a delivery system for targeted cells. These capabilities might play a role in their ability to promote tooth regeneration.

Stimuli-responsive graphene oxide and methotrexate-loaded magnetic nanoparticles for breast cancer-targeted therapy.

Nanocomposites of graphene oxide (GO) loaded with PEGylated superparamagnetic iron oxide nanoparticles and grafted with methotrexate and stimuli-responsive linkers (GO-SPION-MTX) were developed for photothermal and chemotherapy of breast cancer. PEGylated SPIONs were synthesized and conjugated with chemotherapeutic targeting agent MTX, which were then loaded on GO to prepare GO-SPION-MTX nanocomposites. To evaluate the photothermal effect of the nanocomposites, they were examined in breast cancer cell lines with low doses of near-infrared (NIR) laser radiation with/without acetazolamide.

Folate receptor-mediated delivery of 1-MDT-loaded mesoporous silica magnetic nanoparticles to target breast cancer cells.

The efficiency of mesoporous silica magnetic nanoparticles (MSMNP) as a targeted drug-delivery system was investigated. The superparamagnetic iron oxide nanoparticles (NP) were synthesized, coated with mesoporous silica and conjugated with polyethylene glycol and methotrexate. Next, 1-methyl-D-tryptophan was loaded into the prepared nanosystems (NS).

Recent advances in breast cancer immunotherapy: The promising impact of nanomedicines.

Breast cancer (BC) is one of the prevalent cancers among women. Generally, the treatment of BC is mostly based on several prominent strategies, including chemotherapy, surgery, endocrine therapy, molecular targeted therapy, and radiation. Owing to the growing knowledge about the complexity of BC pathobiology, immunotherapy as a promising treatment modality has substantially improved the patients' care in the clinic.

Graphene-based multifunctional nanosystems for simultaneous detection and treatment of breast cancer.

Breast cancer is one of the most life-threatening malignancies with high mortality among women. Chemotherapy, radiotherapy, surgical operation, and combination therapy are commonly applied modalities in breast cancer therapy. However, the full treatment of the disease is often failed because of the formation of a permissive milieu, so-called tumor microenvironment (TME).

Piperacillin Encapsulation in Nanoliposomes Using Modified Freeze-Drying of a Monophase Solution Method: Preparation, Characterization and In Vitro Antibacterial Activity.
