How Is the Language of Imagery in lyric’s of Amir Khosro Dehlavi
Whenever there is an amazing resurrection in a nation’s language which leads to create an artistic masterpiece in that language, it is called literature. For this reason, we can differentiate between literary language and daily or spoken language. Writers and literates from various countries will often try to utilize a literary approach in order to make their utterances and poems more attractive and popular through the use of written imagery and artily, illustratively capturing the emotion of the written words. Amir Khosro Dehlavi; who is a well-known Hindi poet, has mastered the illustrative nature of the Farsi language to compose his euphonious lyric poems. In reviewing his work, we will try to evaluate the context of his poems and the way he has used imaginary and artily language structures, consisting of words, combinations, sentences and phrases in his lyrics, as well as evaluating the way he introduces an imagery approach to his poems
Artificial intelligence ethics in precision oncology: balancing advancements in technology with patient privacy and autonomy
Precision oncology is a rapidly evolving field that uses advanced technologies to deliver personalized cancer care based on a patient’s unique genetic and clinical profile. The use of artificial intelligence (AI) in precision oncology has shown great potential to improve diagnosis, treatment planning, and treatment outcomes. However, the integration of AI in precision oncology also raises important ethical considerations related to patient privacy, autonomy, and protection from bias. In this opinion paper, an overview is provided of previous studies that have explored the use of AI in precision oncology and the ethical considerations associated with this technology. The conclusions of these studies are compared, and the importance of approaching the use of AI in precision oncology with caution is emphasized. It is stressed that patient privacy, autonomy, and protection from bias should be made central to the development and use of AI in precision oncology. Clear guidelines and regulations must be established to ensure that AI is used ethically and for the benefit of patients. The use of AI in precision oncology has the potential to revolutionize cancer care, but it should be ensured that it striked a balance between advancements in technology and ethical considerations. In conclusion, the use of AI in precision oncology is a promising development that has the potential to improve cancer outcomes. However, ethical considerations related to patient privacy, autonomy, and protection from bias must be central to the development and use of AI in precision oncology

Combinational system of lipid-based nanocarriers and biodegradable polymers for wound healing: an updated review
Skin wounds have imposed serious socioeconomic burdens on healthcare providers and patients. There are just more than 25,000 burn injury-related deaths reported each year. Conventional treatments do not often allow the re-establishment of the function of affected regions and structures, resulting in dehydration and wound infections. Many nanocarriers, such as lipid-based systems or biobased and biodegradable polymers and their associated platforms, are favorable in wound healing due to their ability to promote cell adhesion and migration, thus improving wound healing and reducing scarring. Hence, many researchers have focused on developing new wound dressings based on such compounds with desirable effects. However, when applied in wound healing, some problems occur, such as the high cost of public health, novel treatments emphasizing reduced healthcare costs, and increasing quality of treatment outcomes. The integrated hybrid systems of lipid-based nanocarriers (LNCs) and polymer-based systems can be promising as the solution for the above problems in the wound healing process. Furthermore, novel drug delivery systems showed more effective release of therapeutic agents, suitable mimicking of the physiological environment, and improvement in the function of the single system. This review highlights recent advances in lipid-based systems and the role of lipid-based carriers and biodegradable polymers in wound healing
A Review on biomedical application of polysaccharide-based hydrogels with a focus on drug delivery systems
Over the last years of research on drug delivery systems (DDSs), natural polymer-based 18 hydrogels have shown many scientific advances due to their intrinsic properties and a wide variety 19 of potential applications. While drug efficacy and cytotoxicity play a key role, adopting a proper 20 DDS is crucial to preserve the drug along the route of administration and possess desired therapeu-21 tic effect at the targeted site. Thus, drug delivery technology can be used to overcome the difficulties 22 of maintaining drugs at a physiologically related serum concentration for prolonged periods. Due 23 to their outstanding biocompatibility, polysaccharides have been thoroughly researched as a bio-24 logical material for DDS advancement. To formulate a modified DDS, polysaccharides can cross-25 link with different molecules, resulting in hydrogels. According to our recent findings, targeted 26 drug delivery at a certain spot occurs due to external stimulation like temperature, pH, glucose, or 27 light. As an adjustable biomedical device, the hydrogel has tremendous potential for nanotech ap-28 plications in the involved health area like pharmaceutical and biomedical engineering. An overview 29 of hydrogel characteristics and functionalities is provided in this review. We focus on discussing 30 the various kinds of hydrogel-based on their potential for effectively delivering drugs that are made 31 of polysaccharides
Folate-Targeted Curcumin-Loaded Niosomes for Site-Specific Delivery in Breast Cancer Treatment: In Silico and In Vitro Study
As the most common cancer in women, efforts have been made to develop novel nanomedicine-based therapeutics for breast cancer. In the present study, the in silico curcumin (Cur) properties were investigated, and we found some important drawbacks of Cur. To enhance cancer therapeutics of Cur, three different nonionic surfactants (span 20, 60, and 80) were used to prepare various Cur-loaded niosomes (Nio-Cur). Then, fabricated Nio-Cur were decorated with folic acid (FA) and polyethylene glycol (PEG) for breast cancer suppression. For PEG-FA@Nio-Cur, the gene expression levels of Bax and p53 were higher compared to free drug and Nio-Cur. With PEG-FA-decorated Nio-Cur, levels of Bcl2 were lower than the free drug and Nio-Cur. When MCF7 and 4T1 cell uptake tests of PEG-FA@Nio-Cur and Nio-Cur were investigated, the results showed that the PEG-FA-modified niosomes exhibited the most preponderant endocytosis. In vitro experiments demonstrate that PEG-FA@Nio-Cur is a promising strategy for the delivery of Cur in breast cancer therapy. Breast cancer cells absorbed the prepared nanoformulations and exhibited sustained drug release characteristics
