Thyroid function in pyridoxine-deficient young rats

In pyridopaminedoxine-deficient young rats hypothalamic serum TSH concentration was detected. Highly signifiserotonin was decreased with no changes in the cant decreases in the content of pituitary TSH and in and noradrenaline content. Serum the number of pituitary thyrotroph secretory granules and tri-iodothyronine concentrations were were found. These results suo mmuuchch lower in the deficient rats as compared to thyroidism of suggest that the hypocontrols. No significant of hypothalamicp yorirdigoxinin.e -deficient young rats might bbee difference between deficient and control groups in the

Message Integrity in the World Wide Web: Use of Nested Hash Function and a Fast Stream Cipher

The focus of this work is to provide authentication and confidentiality of messages in a swift and cost effective manner to suit the fast growing Internet applications. A nested hash function with lower computational and storage demands is designed with a view to providing authentication as also to encrypt the message as well as the hash code using a fast stream cipher MAJE4 with a variable key size of 128-bit or 256-bit for achieving confidentiality. Both nested Hash function and MAJE4 stream cipher algorithm use primitive computational operators commonly found in microprocessors; this makes the method simple and fast to implement both in hardware and software. Since the memory requirement is less, it can be used for handheld devices for security purposes.
