Homelessness is a social as well as legal stigma on a Country's development index. In addition homeless people are exposed to increased incidence of diseases and accidents. Mangalore city, a bustling city located in Southern costal region of India, has seen tremendous growth in the past few years; with this the problem of migrants and homeless has also increased. This has invited a spectrum of problems relating to law and order including frequent incidences of unclaimed dead bodies, both due to natural and unnatural causes. This autopsy based study tries to highlight the situation of picture of homeless deaths in Mangalore and the problems faced by the Law enforcing authorities.

The presence of the Echimyidae Eumysopinae Clyomys in Ensenadan (Early-Middle Pleistocene) sediments cropping out northeast of Mar del Plata and south of Necochea (costal region of Buenos Aires province, Argentina) is reported. This is the first citation of Clyomys in Argentina and the first post-Pliocene record of echymids at this latitude. These remains represent a species closely related to the extant representatives of the genus, which live at least 1600 km north of the new localities. These fossils suggest that a southward expansion of the Brazilian fauna occurred during a warm and humid pulse in the Pleistocene.

A method has been developed that enables the transpulmonary pressure to be measured directly over most of the costal region of animals without introduction of any device into the pleural space. Pleural surface pressure was atmospheric in the lowermost part of the lung of rabbits and dogs in the lateral, supine and prone postures, it was subatmospheric over the rest, and at all levels in the head-up posture, it was positive in the dependent part in the head-down posture. For a given species and posture pleural surface pressure was uniquely related to the percentage of the lung maximal height and no systematic differences were found at a given height. In all points investigated pleural surface pressure was higher than pleural liquid pressure. While pleural liquid pressure at the top of the lung decreases proportionally to the lung height, pleural surface pressure at the top changes less, not only because the overall vertical gradient of transpulmonary pressure is smaller than that of pleural liquid, but also because it decreases with the increase of the size.

Single unit electrical activity has been recorded from neurons in the Th8 and Th9 segments of the spinal cord in chloralose-anesthetized cats. These neurons had cutaneous receptive fields in the right costal region from which they could be driven by noxious and/or innocuous stimulation of the skin. They could also be activated by distensions of the biliary system but only at noxious intensities of visceral stimulation. No viscero-somatic convergent neurons have been found responding to innocuous visceral stimulation.
