The primary function of the stomach is to prepare food for digestion and absorption by the intestine. Acid production is the unique and central component of the stomach's contribution to the digestive process. Acid bathes the food bolus while stored in the stomach, facilitating digestion. An intact defense against mucosal damage by the stomach's acid is essential to avoid ulceration. This artic...

The concept that a barrier exists between the blood and the brain was first formulated nearly a century ago. Colored dyes injected into the circulation of laboratory animals stained all tissues except the brain. However, when the same dyes were introduced into cerebral spinal fluid (CSF), the liquid that bathes, nourishes, and cushions the brain and spinal cord, brain cells were readily stained...

The spermathecae of Eurycea cirrigera are exocrine glands in the cloaca that secrete a substance that bathes sperm stored in the lumen after mating and prior to oviposition. Many sperm remain in the spermathecae after oviposition, and the spermathecal epithelium becomes spermiophagic. Pseudopodia enclose sperm into endocytic vacuoles. The vacuoles become associated with primary lysosomes in the...

the influences of anionic sodium dodecylsulfate (sds) and cationic hexadecyltrimethylammonium bromide (htab) surfactants on the incorporation and distribution of barium hexaferrite nanoparticles in the electrodeposited cofe-bafe12o19 composite thin films were studied. sulphate bathes with natural ph containing 0 to 2 g/l surfactants were used for electroplating at room temperature. field emissi...

Cryptography is the study of techniques which is used to communicate, store in forma tion or data securely, without being intercepted by third parties. In the real world, there are so many organizations working on large databases over a public network. The security of data is the primary concern in the public network. Encryption is the mos t commonly used technique where transactions continuous...

Invertebrate cardiovascular systems have historically been viewed as sluggish, poorly regulated, and “open”, where blood bathes the tissues directly as it moves through a system of ill-defined sinuses and/or lacunae without an endothelial boundary. When examining cardiovascular/circulatory morphology and physiology in a broader evolutionary context, one can question the very nature of the defin...
