Abstract: Hematological malignancies (HMs) are a heterogeneous group of blood neoplasia generally characterized by abnormal blood-cell production. Detection of HMs-specific molecular biomarkers (e.g., surface antigens, nucleic acid, and proteomic biomarkers) is crucial in determining clinical states and monitoring disease progression. Early diagnosis of HMs, followed by an effective treatment, can remarkably extend overall survival of patients. However, traditional and advanced HMs’ diagnostic strategies still lack selectivity and sensitivity. More importantly, commercially available chemotherapeutic drugs are losing their efficacy due to adverse effects, and many patients develop resistance against these drugs. To overcome these limitations, the development of novel potent and reliable theranostic agents is urgently needed to diagnose and combat HMs at an early stage. Recently, gold nanomaterials (GNMs) have shown promise in the diagnosis and treatment of HMs. Magnetic resonance and the surface-plasmon-resonance properties of GNMs have made them a suitable candidate in the diagnosis of HMs via magnetic-resonance imaging and colorimetric or electrochemical sensing of cancer-specific biomarkers. Furthermore, GNMs-based photodynamic therapy, photothermal therapy, radiation therapy, and targeted drug delivery enhanced the selectivity and efficacy of anticancer drugs or drug candidates. Therefore, surface-tuned GNMs could be used as sensitive, reliable, and accurate early HMs, metastatic HMs, and MRD-detection tools, as well as selective, potent anticancer agents. However, GNMs may induce endothelial leakage to exacerbate cancer metastasis. Studies using clinical patient s les, patient-derived HMs models, or healthy-animal models could give a precise idea about their theranostic potential as well as biocompatibility. The present review will investigate the theranostic potential of vectorized GNMs in HMs and future challenges before clinical theranostic applications in HMs.

Abstract: Breast cancer is the second leading cause of death in women worldwide. The extremely fast rate of metastasis and ability to develop resistance mechanism to all the conventional drugs make them very difficult to treat which are the causes of high morbidity and mortality of breast cancer patients. Scientists throughout the world have been focusing on the early detection of breast tumor so that treatment can be started at the very early stage. Moreover, conventional treatment processes such as chemotherapy, radiotherapy, and local surgery suffer from various limitations including toxicity, genetic mutation of normal cells, and spreading of cancer cells to healthy tissues. Therefore, new treatment regimens with minimum toxicity to normal cells need to be urgently developed. Iron oxide nanoparticles have been widely used for targeting hyperthermia and imaging of breast cancer cells. They can be conjugated with drugs, proteins, enzymes, antibodies or nucleotides to deliver them to target organs, tissues or tumors using external magnetic field. Iron oxide nanoparticles have been successfully used as theranostic agents for breast cancer both in vitro and in vivo. Furthermore, their functionalization with drugs or functional biomolecules enhance their drug delivery efficiency and reduces the systemic toxicity of drugs. This review mainly focuses on the versatile applications of superparamagnetic iron oxide nanoparticles on the diagnosis, treatment, and detecting progress of breast cancer treatment. Their wide application is because of their excellent superparamagnetic, biocompatible and biodegradable properties.

Abstract: With the background of snowballing threat of skin wound to public health and economy, this study was undertaken utilizing xanthan gum (Xnt), citric acid (C), gelatin (Gel), glutaraldehyde (G) and HPLC-grade water to fabricate a series of composite hydrogels i.e. Xnt, Xnt:C, Xnt:Gel(3):G, Xnt:C:Gel(3):G, Xnt:Gel(5):G, Xnt:C:Gel(5):G for investigating their wound healing efficacy in experimental rat skin wound model. Physicochemical characterization revealed that all the composite hydrogels contained more than 90% water. The hydrogels displayed swelling ability, biodegradability, good polymeric networks and porosity. Fourier Transform Infrared Spectroscopy (FT-IR) studies confirmed the presence of bound water and free, intra and inter molecular bound hydrogen bonded OH and NH in the hydrogels. All the hydrogels showed significant wound healing potency in experimental deep second degree skin burns in rats compared to controls. 20 days post-application of hydrogels, Xnt:Gel(3):G, Xnt:Gel(5):G and Xnt:C:Gel(5):G-treated wounds showed better recovery compared to other composite hydrogels. We conclude that, Xnt:Gel(3):G, Xnt:Gel(5):G and Xnt:C:Gel(5):G might be effective wound dressing material.
