Reconstruction of traumatic lumbar hernias: A case report.

Backround: Traumatic lumbar hernias are not common hernias that are encountered by general or plastic surgery teams, however it is important to understand the anatomy of the hernia in order to be able to correct the flank defect. In our patient, the oblique muscles were sheared off the iliac crest periosteum, however the attachments to the ribs and spine were maintained. We were able to successfully place a pre-peritoneal polypropylene mesh which was secured to the musculature, and re-approximate the oblique muscles to the iliac crest using Mitek QUICKANCHOR sutures.

Geographic variation in thermal tolerance and strategies of heat shock protein expression in the land snail Theba pisana in relation to genetic structure.

Land snails are exposed to conditions of high ambient temperature and low humidity, and their survival depends on a suite of morphological, behavioral, physiological, and molecular adaptations to the specific microhabitat. We tested in six populations of the land snail Theba pisana whether adaptations to different habitats affect their ability to cope with thermal stress and their strategies of heat shock protein (HSP) expression. Levels of Hsp70 and Hsp90 in the foot tissue were measured in field-collected snails and after acclimation to laboratory conditions.

Natural variation in resistance to desiccation and heat shock protein expression in the land snail Theba pisana along a climatic gradient.

Land snails frequently encounter desiccating conditions, and their survival depends on a suite of morphological, physiological, and molecular adaptations to the specific microhabitat. Strategies of survival can be determined by integrating information from various levels of biological organization. In this study, we used a combination of physiological parameters related to water economy and molecular factors (stress protein expression) to investigate the strategies of survival adopted by seven populations of the Mediterranean-type land snail Theba pisana from different habitats.

The heat shock response in congeneric land snails (Sphincterochila) from different habitats.

Land snails are subject to daily and seasonal variations in temperature and in water availability, and use heat shock proteins (HSPs) as part of their survival strategy. We used experimental heat stress to test whether adaptation to different habitats affects HSP expression in two closely related Sphincterochila snail species, a desert species, Sphincterochila zonata, and a Mediterranean-type species, Sphincterochila cariosa. Our findings show that in S.

Heat shock proteins and survival strategies in congeneric land snails (Sphincterochila) from different habitats.

Polmunate land snails are subject to stress conditions in their terrestrial habitat, and depend on a range of behavioural, physiological and biochemical adaptations for coping with problems of maintaining water, ionic and thermal balance. The involvement of the heat shock protein (HSP) machinery in land snails was demonstrated following short-term experimental aestivation and heat stress, suggesting that land snails use HSPs as part of their survival strategy. As climatic variation was found to be associated with HSP expression, we tested whether adaptation of land snails to different habitats affects HSP expression in two closely related Sphincterochila snail species, a desert species Sphincterochila zonata and a Mediterranean-type species Sphincterochila cariosa.

Heat shock protein expression in relation to reproductive cycle in land snails: Implications for survival.

Land snails are subject to daily and seasonal variations in temperature and in water availability and use heat shock proteins (HSPs) as part of their survival strategy. We tested whether the reproductive cycle of land snails affects the endogenous levels of HSPs, and their involvement in the reproductive process. We examined HSP levels in the foot tissue of two Sphincterochila species, S.

Natural annual cycle of heat shock protein expression in land snails: desert versus Mediterranean species of Sphincterochila.

Land snails are subject to daily and seasonal variations in temperature and in water availability, and have evolved annual cycles of activity and aestivation as part of their survival strategy. We tested in the field whether adaptation to different habitats affects the endogenous levels of heat shock proteins (HSPs) in two closely related Sphincterochila snail species, a desiccation-resistant desert species, Sphincterochila zonata, and a Mediterranean-type, desiccation-sensitive species, S. cariosa.

Heat shock proteins and resistance to desiccation in congeneric land snails.

Land snails are subject to daily and seasonal variations in temperature and in water availability and depend on a range of behavioral and physiological adaptations for coping with problems of maintaining water, ionic, and thermal balance. Heat shock proteins (HSPs) are a multigene family of proteins whose expression is induced by a variety of stress agents. We used experimental desiccation to test whether adaptation to different habitats affects HSP expression in two closely related Sphincterochila snail species, a desiccation-resistant, desert species Sphincterochila zonata, and a Mediterranean-type, desiccation-sensitive species Sphincterochila cariosa.

Visual versus non-visual selection of shell colour in an Israeli freshwater snail.

The Israeli freshwater snail Theodoxus jordani exhibits high variability both in shell colour and shell pattern.In most localities in Israel, more than 80% of the snails are black regardless of the colour of their background. Within Lake Kinneret, however, there is a significant association between the relative frequency of dark patterned shells and the distribution of a black (basalt) background.
