Delivery of Genetic Materials for the Management of Biological Disorders: Advancement and Roles of Polysaccharides and their Derivatives.

Advancement in nanotechnology leads to the development of polysaccharides which are very efficient carriers in delivering therapeutic substances like drugs, proteins, and genes. This review describes the role of polysaccharides and their derivatives in the cellular targeting of genetic materials for the treatment of various biological disorders. Applications, challenges, advantages, and disadvantages of polysaccharides used in gene delivery are discussed in the manuscript. Cationic and natural polysaccharides are generally used for RNA and DNA delivery and exhibit better performance in gene transfection. After a substantial literature survey, it can be concluded that different polysaccharides and their derivatives are effectively used in the delivery of genetic material. Natural polysaccharides are widely used due to their advantageous properties like biocompatibility, biodegradability, and low toxicity in the biological environment.

Role of Polysaccharides Mimetic Components in Targeted Cancer Treatment.

Organic or inorganic compounds are synthesized or formulated to demonstrate their therapeutic actions, like a natural polysaccharide in the body. Polysaccharides, the major type of natural polymers, are biologically active, non-toxic, hydrophilic, and biodegradable and exhibit various properties. This manuscript is focused on delivering anticancer drugs with the help of mimetic components of polysaccharides. The data presented in this manuscript were obtained from PubMed, Elsevier, Taylor & Francis and Bentham Science Journals. Most chemotherapeutics are toxic to the human body, have a narrow therapeutic index, sluggish pharmaceutical delivery mechanisms, and are poorly soluble in water. The use of mimetic components of polysaccharides leads to the enhancement of the solubility of drugs in the biological environment. The current review summarizes the use of mimetic components of polysaccharides along with anticancer agents, which are capable of inhibiting the growth of cancerous cells in the body and exhibiting lesser adverse effects in the biological system compared to other therapies.

Skin Diseases and their Treatment Strategies in Sub-Saharan African Regions.

BACKGROUND: In the rural areas of sub-Saharan African regions, skin diseases are so common. Due to which the population of the sub-Saharan region suffers from different types of skin disorders. In these regions, many treatment options are not available for the treatment of skin disease. AIM: The current study aims to discuss various skin diseases and their treatment strategies, specifically in sub-Saharan African regions. METHODS: Extensive literature survey was carried out by using Scopus, Science Direct, Elsevier, Google scholar and Bentham science databases. RESULTS AND DISCUSSION: It was demonstrated from the literature surveys that different effective techniques are used in the management of skin disease. In the result, it was shown that the condition of the disease is at a dangerous level which must be controlled. CONCLUSION: It is concluded from the manuscript that the skin disorder in the sub-Saharan region is at a very dangerous level. The research must be done to develop a better understanding of the disease and its treatment.

Understanding and advancement in gold nanoparticle targeted photothermal therapy of cancer.

The present communication summarizes the importance, understanding and advancement in the photothermal therapy of cancer using gold nanoparticles. Photothermal therapy was used earlier as a single line therapy, but using a combination of photothermal therapy with other therapies like immunotherapy, chemotherapy, photodynamic therapy; efficient therapy management can be achieved. As it was discussed in many studies that gold nanoparticles are treated as idyllic photothermal transducers due to their structural dimensions, which enables them to strongly absorb near infrared light. Gold nanoparticles which are mediated for photothermal therapy can warn cancer cells to chemotherapy, regulate genes and immunotherapy by enhancing the cell permeability and intracellular delivery. The necrosis process and apoptosis depend on the power of laser and temperature within the cancerous tissues which are reached during irradiation. Cells death mechanism is also important because the cells which died through the process of necrosis can endorse secondary tumor growth while the cells which died through apoptosis may provoke the immune response to inhibit the development of secondary tumor growth. To decrease the in vivo barriers, gold nanostructures are again modified with targeting ligand and bio-responsive linker. The manuscript summarizes that the use of gold nanoparticles is capable of inhibiting the growth of cancerous cells by using photothermal therapy which has lesser adverse effects compared to other line therapies.

Fabrication and Characterization of Chitosan-Tamarind Seed Polysaccharide Composite Film for Transdermal Delivery of Protein/Peptide.

Transdermal drug delivery is used to deliver a drug by eliminating the first-pass metabolism, which increases the bioavailability of the drug. The present study aims to formulate the chitosan-tamarind seed polysaccharide composite films and evaluate for the delivery of protein/peptide molecules. Nine formulations were prepared and evaluated by using different parameters, such as physical appearance, folding endurance, thickness of film, surface pH, weight variation, drug content, surface morphology, percentage moisture intake and uptake, drug release kinetics, and drug permeability. The film weight variance was observed between 0.34 ± 0.002 to 0.47 ± 0.003 g. The drug level of the prepared films was found to be between 96 ± 1.21 and 98 ± 1.33µg. Their intake of moisture ranged between 2.83 ± 0.002 and 3.76 ± 0.001 (%). The moisture absorption of the films ranged from 5.33 ± 0.22 to 10.02 ± 0.61 (%). SEM images revealed a smooth film surface, while minor cracks were found in the film after permeation tests. During the first 4 days, drug release was between 13.75 ± 1.64% and 22.54 ± 1.34% and from day 5 to day 6, it was between 72.67 ± 2.13% and 78.33 ± 3.13%. Drug permeation during the first 4 days was 15.78 ± 1.23 %. Drug permeation (%) during the first 4 days was between 15.78 ± 1.23 and 22.49 ± 1.29 and from day 5 to day 6, it was between 71.49 ± 3.21 and 77.93 ± 3.20.
