Al caer la noche, miles de murciélagos insectívoros y frugívoros inician su salida de la caverna para alimentarse y las serpientes ratoneras manchadas (Elaphe flavirufa) toman sus posiciones para atacar. Lentamente comienzan a descolgarse por los lugares donde existe un mayor flujo de murciélagos, hasta quedar suspendidas de la cola en toda su extensión. Balanceándose rítmicamente, esperan a que su presa pase cerca de ellas y, en un rápido movimiento, atrapan al murciélago enrollándolo con su cuerpo para asfixiarlo con la constricción de sus músculos y posteriormente proceder a tragarlo entero. El libro presenta un extraordinario testimonio escrito y fotográfico de esta investigación, la cual se suma a otro descubrimiento único, los estromatolitos de la laguna Chichankanab, donde las bacterias cianofitas son protagonistas de otro caso denominado El misterio de las Almejas Cautivas ¿Interesado aquí encontrarás las respuestas. ····· 103611402

für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Liver fibrosis is a severe medical problem, which currently doesn`t have enough biological markers to accurately detect its progression. This fact is one of the greatest factors preventing the improvement of therapies available today. This book, therefore, suggests an enzyme called Heparanase, as a new biological marker for the progression and regression of liver fibrosis. In previous studies, Haparanase was shown to have a role in a wide range of normal and pathological processes, such as, angiogenesis, tumor metastasis and wound healing responses. Expressions of heparanase and key extracellular matrix (ECM) remodeling enzymes were analyzed in fibrotic rats, hepatic stellate cell (HSC) lines and heparanase over-expressing HSC lines. Heparanase activity and cell localization in activated HSCs were analyzed as well. The analyses should help shed some light on this new and exciting possible role of heparanase in liver fibrosis and recovery, and should be especially useful to students and professionals in Medical Sciences and Biology fields, or anyone else who may be interested in learning more about the biology behind liver fibrosis, or how studies are done in these fields. ····· 103611223

One such natural enemy is the larval endoparasitoid Cotesia sesamiae (Cameron). Two biotypes of C. sesamiae have been reported with differential abilities to suppress the immune system of B. fusca. Eggs of a C. sesamiae population from Mombasa were encapsulated while eggs of a population from western Kenya were not. Total and differential haemocytes were counted in larvae of B. fusca at six different times after being exposed to parasitoids from western Kenya, and the eastern coastal area of Kenya. The total number of haemocytes in larvae parasitized by the C. sesamiae population from Mombasa was higher as compared to larvae parasitized by the C. sesamiae population from western Kenya. Fourth-instar B. fusca larvae were treated with calyx fluid from C. sesamiae from western Kenya before offering them to C. sesamiae from the coast for oviposition, and found that the eggs were not encapsulated. The Wolbachia infection of the coastal type did not play a role in the encapsulation response of the host. ····· 103611216

Therefore it is an important model to study bacterial pathogenicity. The disease spectrum in human includes gastroenteritis, septicemia, traumatic and aquatic wound infections. The world wide interest on this bacteria is increasing on the occurance of multidrug resistance and involvement in severe gastroenteritis in children. Presence of a virulence plasmid has been observed in clinical isolates. But their exact role in disease establishment and virulence is not clear. The goal is to unfold the role of plasmid in disease establishment in-vivo and triggering apoptosis in-vitro. Apoptosis or programmed cell death is actually a double sided sword that helps to maintain body homeostasis. Apoptosis triggering by pathogenic bacteria is paving a new way for future research which will help for better understanding of infectious diseases and provide new tools to control future outbreaks of new strains. ····· 103611076

Katepwa (spring sw) and cv. Beaver (winter ww) was studied. To distinguish cellular responses, parallel measurements were carried out on embryogenic callus. Seedlings were grown either at 20ºC (control treatment), or at 20ºC followed by transfer to 4ºC for 14 d and then returned to 20ºC (cold treatment). The growth response of both cultivars was reduced at 4ºC but the shoot meristem of ww at 4ºC exhibited a faster relative growth rate and a shorter tissue doubling time than sw. This suggests that vernalization stimulates cell division in the shoot meristem. Interphase cells in the root meristem of both cultivars/treatments were smaller but had larger nuclei than those in the callus. More cells accumulated in G1 at 4ºC in ww than at 20ºC. In vitro and, to a lesser extent in vivo, the majority of cells were polyploid irrespective of cultivar/treatment. The interphase cell protein content increased significantly with increased nuclear DNA C-value regardless of cultivar/treatment. For ww in vivo, protein/C-value remained unchanged by transfer to 4ºC, but that for sw decreased. ····· 10361490
