The research focuses on the design and synthesis of photosensitive ruthenium nitrosyl complexes, exploring their photochemical behavior and nitric oxide (NO) dissociation under UV and visible light. The study investigates how different substituents in the ligand frames affect NO reactivity and scavenging capabilities. It also examines the transfer of photoreleased NO to reduced myoglobin in a phosphate buffer solution when illuminated. Quantitative analysis of NO release and other reactive species was conducted using Griess reagent and DPPH radical quenching assays.

Osteology is the study of the structure and function of the skeleton and bony structures. This new edition is a comprehensive guide to human osteology for postgraduate medical students. Beginning with an introduction to the skeletal system, the following chapters cover bones in different anatomical regions – upper and lower limb, sternum and ribs, vertebral column, head and neck, and skull. Chapters are followed by numerous images illustrating muscle attachments. The fourth edition has been fully revised to provide students with the latest information in the field. Highly illustrated with nearly 500 clinical photographs and diagrams, the book also includes questions and answers to help students prepare for examinations. Key points Fully revised, new edition providing latest information in field of osteology Covers bones and muscle attachments in each anatomical region Highly illustrated with clinical photographs and diagrams Previous edition (9788184483000) published in 2008

Cryptography is a process which consists of two parts that are called as encryption and decryption processes. The encryption process can be defined as converting the original message which is named as plain-text to an inscrutable form which is named as cipher-text by an algorithm with secret keys.The model for encryption and decryption of an image is proposed here with the objectives to have confidentiality and security in transmission of the image based data. The chaos and wavelet based cryptographic algorithms and have suggested some new and efficient ways to develop secure image encryption techniques.The behavior of system is verified with different key values at the receiver end to study the relation among plain image and cipher image. Histogram uniformity is also studied to check tonal distribution.
