Article Synopsis
  • - Alzheimer's disease (AD) requires early diagnosis, and a new SERS sensor made from biomass-derived carbon fibers with silver nanoparticles (Ag@CFs) is being used for detecting amyloid beta Aβ (25-35) to aid in this process.
  • - The sensor's performance was tested with rhodamine 6G, showing a significant enhancement that proves its capability to detect very low concentrations of amyloid beta.
  • - This innovative Ag@CFs-based SERS sensor could offer a non-invasive, cost-effective method for early AD diagnosis, potentially changing how the disease is identified.

Article Synopsis
  • The study focuses on developing solid lipid nanoparticles (SLNs) loaded with the chemotherapy drug irinotecan and the isoflavonoid daidzein, coated with materials like hyaluronic acid for targeted delivery to colon cancer cells.
  • These nanoparticles were characterized for size, charge, and compatibility, revealing spherical shapes, high entrapment efficiency, and effective drug release patterns.
  • In vitro and in vivo tests showed that these SLNs reduced cancer cell viability, promoted cell cycle arrest, and improved colon tissue structure, suggesting great potential for treating colon cancer.

Background Major depressive disorder (MDD) is a debilitating mood disorder that increases the risk of metabolic syndrome (MS), emphasizing the need for mental and physical health treatments. Although many studies have linked atypical antipsychotics to metabolic disturbances, there is limited evidence linking selective serotonin reuptake inhibitor use to MS. This study aimed to assess the risk of MS among patients with MDD who were administered vortioxetine and fluoxetine.

Improper diet and physical inactivity are environmental risk factors for breast cancer (BC). This study evaluated the association of dietary risk factors and physical activities with different molecular subtypes of BC. We conducted a case-control study among 130 cases of BC and 150 age-matched controls.

Article Synopsis
  • - The study developed a self-nanoemulsifying drug delivery system (SNEDDS) using aqueous leaf extracts of two plants, JA and PG, to boost platelet counts and tested its effectiveness in Wistar rats.
  • - A ternary phase diagram helped identify suitable self-emulsifying components, with the optimized SNEDDS showing specific globule sizes, indicating stability across different pH levels without phase separation.
  • - Results indicated that the combined SNEDDS formulation notably increased platelet counts in treated rats compared to a standard drug, Caripill, demonstrating its potential as a therapeutic option for platelet deficiencies.

Article Synopsis
  • The study focuses on creating chitosan nanoparticles (CS-NPs) loaded with gemcitabine and capped with folic acid and silver nanoparticles, aimed at improving cancer treatment through targeted drug delivery.
  • Characterization techniques such as dynamic light scattering and transmission electron microscopy confirmed the size and properties of the nanoparticles, which were influenced by their compositions and conditions.
  • In vitro testing showed that the CS-NPs effectively released the drug in lower pH environments and had higher cytotoxicity on human breast cancer cells compared to neutral pH levels, indicating potential for site-specific cancer therapy.

Antibiotic resistance in the context of treating malarial infections is a major challenge in India. Home remedies such as thulasi leaves (), black pepper seeds (, clove buds (), cinnamon bark (), and nilavembu whole plant powder () were taken to explore antimalarial and methicillin-resistant (MRSA) activity. Among the five extracts, the best two extracts, and extract, showed the presence of Quercetin.

Background: Silver nanoparticles (AgNPs) have attracted considerable interest in the medical industry due to their physicochemical properties, small size, and surface plasmon behavior. Their smaller particle size and instability in blood circulation leads to toxicity due to its aggregation as Ag+ ions and accumulation at the deepseated organ. In the present study, we aimed at reducing the toxicity of AgNPs by conjugation with an anticancer drug GEM and to improve their internalization through folate receptors-mediated endocytosis by capping the nanoparticles with folic acid (FA).

Article Synopsis
  • Combined extracts of Phyllanthus niruri, Croton tiglium, and Zingiber officinale were explored for their potential uses in medicine, particularly when formulated as ethosomes for better drug delivery.
  • The study aimed to analyze the cytotoxic effects of these extracts, both alone and when encapsulated in ethosomes, using skin cells treated with testosterone for comparison.
  • Results indicated that the ethosomes effectively inhibited testosterone effects, improving cell viability similarly to a standard medication, minoxidil, without harming the skin in preclinical tests.

Article Synopsis
  • Androgenetic alopecia, a leading cause of baldness, is linked to the buildup of dihydrotestosterone (DHT) at specific receptors in hair follicles.
  • Finasteride (FIN) is a drug that inhibits the enzyme responsible for converting testosterone to DHT, but it can lead to infertility when taken orally by men.
  • Researchers developed small ethosomes (100-300 nm in size) to improve the delivery of FIN to the scalp, finding that these ethosomes effectively penetrated skin samples and could reach hair follicle receptors, although adding more permeation enhancers may not be ideal for targeting the treatment area.

Article Synopsis
  • * A study focused on diabetic inpatients revealed that 70% of the screened prescriptions contained at least one potential drug-drug interaction, primarily involving cardiac, analgesic, and antibiotic medications.
  • * The findings indicated that interactions varied in severity, with 68% being minor, 66% moderate, and 20% severe; thus, a clinical pharmacist's role in screening prescriptions is essential for preventing serious drug interactions in diabetic patients.

Curcumin (diferuloylmethane) possesses low bioavailability due to its poor solubility, permeability and rapid metabolism. Solid Lipid Nanoparticle of curcumin was prepared by high-speed homogenization technique. Stearic acid was used as a lipid, tween 80 as surfactant and various co surfactants were used for the preparation of SLN.

Zidovudine (AZT) is commonly used to treat patients with AIDS, but it is limited by toxicity and high dosing needs. Alternative formulations have been proposed to overcome these drawbacks. The objective of this study was to evaluate process-related variables like hydration and sonication time, rotation speed of evaporation flask, and the effects of charge-inducing agent and centrifugation on zidovudine entrapment and release from niosomes.

Niosomes containing zidovudine (ZDV), an anti-HIV drug for intravenous administration were formulated by a thin-film hydration technique. Proniosomes were prepared in the form of a slurry using beta-cyclodextrin as carrier. The effect of the surfactants Tween and Span and the negative charge-inducing agent dicetylphosphate (DCP) on tissue distribution of niosomes and proniosomes was studied.
