In this study we tried to explore Diazepam as a repurposed drug and tested it in Neuroblastoma (Neuro 2a) cells. Diazepam loaded Poly Lactic Acid Nanoparticles were developed (D-PLA-NPs) using nanoprecipitation method. Entrapment efficiency was found to be ± 99.7% and drug loading was ± 12.88%. The particle size developed was 188.8 nm and zeta potential was −25.6 millivolt. Dissolution profiles were studied in PBS (pH 7.4) or simulated media, almost 50% release was observed within 6 h. In vitro, cytotoxicity was analyzed using MTT assay where dose-dependent cytotoxicity was observed for developed D-PLA-NPs.

Abstract Two novel electrochemiluminescence (ECL) deoxyribosensors are designed for assay of early lung cancer biomarker (NAP2) using the DNA three-way junction (DNA-TWJ) inserted NAP2 binding aptamer between two double-helical stems and labeled with ruthenium (II) complex (Ru) (NBAT-Ru) taken as molecular recognition element. The signal-off ECL deoxyribosensor was fabricated by covalently coupling the 5'-NH2-(CH2)6-NBAT-Ru to glassy carbon electrode surface modified with 4-aminobenzoic acid (4-ABA). After combining NAP2 and NBAT-Ru, the changed conformation of NBAT-Ru altered the distance between Ru complex and e...

Abstract The expression level of miRNA-21 is closely related to the occurrence and development of cancer, especially in gastrointestinal cancer. Monitoring miRNA-21 has clinical application in the diagnosis and evaluation of gastrointestinal cancer. A turn-on ratiometric fluorescence bioassay based on the T7 exonuclease-mediated cyclic enzymatic amplification method was developed for miRNA-21 determination by using carbon dots (CDs) and FAM-labeled ssDNA as the signal source. CDs demonstrated the triple functions of built-in internal fluorescence, probe carrier, and quencher in this strategy. In the absence of miR...

Abstract Development of a mitochondria-targeting fluorescent probe with large Stokes shift and long-wavelength emission was benefit for accurate detection of hypoxic status, which was known as a major factor of the tumor physiology and influence important pathological processes. However, an efficient optical approach for simultaneously achieving such merits was still lacking. In this work, a turn-on fluorescence probe (HBT-NP) was designed to assess the hypoxic condition of tumor cells by detecting nitroreductase (NTR). Probe HBT-NP was constructed by conjugating 4-nitrobenzyl moiety as reaction site for NTR to 2-...

ZinAbstractThe cancer treatment modalities have been developed rapidly with the aim to maximize the absorbed dose toward the cancer cells while sparing the healthy tissues. The use of high atomic number, Z nanomaterials has become interest as it offers the possibilities such as destroying cancer tumor with minimal damage to the healthy tissues. The study aimed to evaluate the role of methylene blue as it reduced the self-polymerization as well as to measure the dose enhancement effect of Zin...

CONCLUSIONS: Non-functional, metastatic Pan-NETs may transform to insulin secreting lesions, with negative impact on prognosis. Therefore, if symptoms as hypoglycemia develops continuous follow-up of clinical parameters, biochemical profiles of pancreatic hormones and histopathological evaluation of proliferation is suggested to detect changes in characteristics of these malignant neoplasms.

Abdel-HamidAbstractColorectal cancer (CRC) is a major public health concern and one of the main causes of cancer-related deaths worldwide. Of different risk factors for developing CRC, obesity plays a vital key role in colorectal carcinogenesis due to the perturbation in the metabolic and lipid profiles of obese candidates. The aim of this study is to decipher the disturbed metabolites associated with CRC susceptibility in at-risk obese populatio...
