METHODS: In this study, fbpA and mazE genes were chosen as new antimicrobial targets and treated with antisense peptide nucleic acid (PNA). Firstly, they were evaluated by bioinformatics and then analyzed by experimental procedures. Secondly, the functionality was evaluated by stress conditions.

RESULTS: Our results interestingly demonstrated that when fbpA and mazE loci of N. meningitidis were targeted by antisense PNA, 8 µM concentration of fbpA-PNA as well as 30 µM concentration of mazE-PNA inhibited the growth of N. meningitides and were found to be bacteriostatic, whereas 10 μM concentration of fbpA-PNA showed bacteriocidal activity.

OBJECTIVE: This review was aimed to critically discuss and conceptualize existing evidences related to the pharmaceutical significance and therapeutic feasibility of multi-functionalization of nanomedicines for early diagnosis and efficient treatment of BC.

RESULTS: Though the implication of nanotechnology-based modalities has revolutionised the outcomes of diagnosis and treatment of BC; however, the clinical translation of these nanomedicines is facing grandeur challenges. These challenges include recognition by the reticuloendothelial system (RES), short plasma half-life, non-specific accumulation in the non-cancerous cells, and expulsion of the drug(s) by the efflux pump. To circumvent these challenges, various adaptations such as PEGylation, conjugation of targeting ligand(s), and siteresponsive behaviour (i.e., pH-responsiveness, biochemical, or thermal-responsiveness) have been adapted. Similarly, multi-functionalization of nanomedicines has emerged as an exceptional strategy to improve the pharmacokinetic profile, specific targetability to the tumor microenvironment (active targeting) and efficient internalization, and to alleviate the expulsion of internalized drug contents by silencing-off efflux pump.

METHODS: Saccharide mapping or enzymatic profiling plays a role in quality control of polysaccharides. Whereby, in vitro and in vivo tests as well as toxicity level discriminating polysaccharides biological activities. Extraction and purification methods are performed in obtaining algal derived polysaccharides followed by chromatographic profiles of their active compounds, structural features, physicochemical properties, and reported biological activities.

RESULTS: Marine algae are capable of synthesizing Glycosaminoglycans (GAGs) and non-GAGs or GAG mimetics such as sulfated glycans. The cell walls of algae are rich in sulfated polysaccharides, including alginate, carrageenan, ulvan and fucoidan. These biopolymers are widely used algal-derived polysaccharides for biological and biomedical applications due to their biocompatibility and availability. They constitute biochemical compounds that have multi-functionalization, therapeutic potential and immunomodulatory abilities, making them promising bioactive products and biomaterials with a wide range of biomedical applications.

AIM: The aim of this paper was to review the role of CMKLR-1 receptor and the potential therapeutic target in the management of chemerin induced type 2 diabetes mellitus and cancer.

PATHOPHYSIOLOGY: Increased chemerin secretion activates an inflammatory response. The inflammatory response will increase the oxidative stress in adipose tissue and consequently results in an insulin-resistant state. The occurrence of inflammation, oxidative stress and insulin resistance leads to the progression of cancers.

METHOD: Therefore, there is a need to improve delivery of therapeutic macromolecules to enable non-invasive delivery routes, less frequent dosing through controlled-release drug delivery, and improved drug targeting to increase efficacy and reduce side effects.

RESULT: Non-invasive administration routes such as intranasal, pulmonary, transdermal, ocular and oral delivery have been attempted intensively by formulating macromolecules into nanoparticulate carriers system such as polymeric and lipidic nanoparticles.

METHODS: Dendrimer mediated cancer therapy is advantageous over conventional chemotherapy, radiotherapy and surgical resection due to reduced systemic toxicity, and molecular level cell injury to cancerous mass, for an appreciable survival of the subject. Recently used dendrimer mediated nanotechnology for oncology aims to conquer these challenges. Dendrimers based nano-constructs are having architectures comparable to that of biological vesicles present in the human body.

RESULTS: Operating with dendrimer technology, proffers the exclusive and novel strategies with numerous applications in cancer management involving diagnostics, therapeutics, imaging, and prognostics by sub-molecular interactions. Dendrimers are designed to acquire the benefits of the malignant tumor morphology and characteristics, i.e. leaky vasculature of tumor, expression of specific cell surface antigen, and rapid proliferation.

OBJECTIVE: Since phytoestrogenic occurrence is high at daily meals for most people worldwide, they focused to study for its beneficiary effects towards developing pharmaceutical drugs for treating various metabolic disorders by observing endocrine disruption.
