Aortic aneurysms and pseudo-aneurysms are a rare occurrence in the pediatric age group. True aneurysms are usually related to infection or to inherited disorders while pseudo-aneurysms occur following trauma or infection. We present a case of a pseudo-aneurysm of the descending thoracic aorta in a 13-month-old child, who presented with life-threatening massive hemoptysis. Though no clear-cut etiologic factor was identified on clinical examination and investigations, presence of neutrophilic infiltration in the wall suggested an infective nature.

Wheat (Triticum aestivum), belonging to poaceae family is a vital constituent of the human diet. At the germinated stage, the leaves of wheat over 6-10 days are commonly called wheatgrass, it contain very good quantity of chlo-rophyll, which shows the structural similarity to haemoglobin molecule hence, known to play a significant role in blood deficiency diseases such as Thalassemia and myelotoxicity in cancer patients during chemotherapy. Moreover, wheatgrass has been reported as the richest source of vitamins, enzymes, minerals, aminoacids, trace elements, phytochemical components and a glycoprotein P4D1 etc. which can stimulate the repair of DNA and RNA in case of their damage. All of them collectively provide a good therapeutic potential against a broad range of ailments including chronic diseases. The recent researchers reporting its antioxidant, anti-arthritic, anti-hyperlipidemic or cardio-protective, anti-diabetic, anti-inflammatory and immunomodulatory activities have made this plant more valuable in herbal research. In the present review attempt is made to focus on the therapeutic potential of wheatgrass against the various chronic diseases.

Since the selection of the Rijndael cryptosystem as a new Advanced Encryption Standard (AES) in 2000, many hardware implementations of AES have been reported. Some of these implementations are optimized for speed, some for area, some for reconfigurability, and some for low-power applications. Again, reversible logic synthesis methodologies have drawn the attention of researchers in recent times, mainly with the prospect of quantum computing becoming a reality, and the potential of reversible logic circuits for providing ultra low-power implementations.Although many of the cryptographic primitives are inherently reversible by nature, very little work has been done towards reversible logic implementations of the same. The only published works relate to reversible implementations of Montgomery multiplication algorithm, which has applications in cryptography. The present paper, possibly for the first time, presents a reversible logic implementation of a block cipher, namely, 128-bit AES. The various AES functional blocks have been synthesized using reversible gates, using which an overall reversible architecture has been proposed. The pipelined version as suggested can only be used in the Electronic Code Book (ECB) mode. The hardware complexity of the implementation has been evaluated using the number of reversible gates required and the quantum cost.
