Plasma renin activity and renin substrate levels were measured during the development of cellophane perinephritis hypertension induced by either a bilateral renal wrap procedure or a wrap-nephrectomy procedure in 28 rabbits. Unoperated and unilaterally nephrectomized controls were also studied. Plasma renin concentration was derived from plasma renin activity and plasma renin substrate levels u...

We put forward a new paradigm for building hybrid encryption schemes from constrained chosen-ciphertext secure (CCCA) key-encapsulation mechanisms (KEMs) plus authenticated symmetric encryption. Constrained chosen-ciphertext security is a new security notion for KEMs that we propose. CCCA has less demanding security requirements than standard chosen-ciphertext (CCA) security (since it requires ...

1. "S" strains of Friedländer's bacillus produce capsules, soluble specific substance, and are of exalted virulence. "S" strains are type-specific and react with only the type-specific antibodies of the homologous types. 2. Immunization with "S" cells induces the formation of antibodies which agglutinate type specifically, precipitate the corresponding soluble specific substance, and protect wh...

As a surgical complication of renal transplantation lymphocele account for as much as 6-18% complications reported by major referential series. The most common cause if lymphatic injury in the course of preparation of the iliac vessels of the recipients, i.e. unligated lymph vessels in the renal hilus of the donor. Other etiological factors, such as acute rejection, urinary obstructions or deca...

The IETF currently discusses fast reroute mechanisms for IP networks (IP FRR) to accelerate the recovery in case of network element failures and to avoid microloops during network-wide routing re-convergence. Several mechanisms are proposed. Loop-free alternates (LFAs) are simple, but they cannot cover all single link and node failures. Not-via addresses are more complex and cover all single fa...

In CRYPTO 2007, Hofheinz and Kiltz formalized a security notion for key encapsulation mechanisms (KEMs), called constrained chosen ciphertext (CCCA) security, which is strictly weaker than ordinary chosen ciphertext (CCA) security, and showed a new composition paradigm for CCA secure hybrid encryption. Thus, CCCA security of a KEM turned out to be quite useful. However, since the notion is rela...

Storage of sperm inside the female genital tract is an integral phase of reproduction in many animal species. The sperm storage site constitutes the arena for sperm activation, sperm competition and female sperm choice. Consequently, to understand animal mating systems information on the processes that occur from sperm transfer to fertilization is required. Here, we focus on sperm activation in...

Renal resident stem cells were previously reported within the renal tubules and papillary area. The aim of the present study was to determine whether renal capsules harbor stem cells and whether this pool can be recruited to the renal parenchyma after ischemic injury. We demonstrated the presence of label-retaining cells throughout the renal capsule, at a density of ∼10 cells/mm(2), and their c...

Experiments were performed to test the hypothesis that the renal interstitial hydrostatic pressure (RIHP) response to acute volume expansion is suppressed in diabetes mellitus. Sprague-Dawley rats received streptozotocin (STZ rats; 65 mg/kg ip) or vehicle (Sham rats). Two weeks later, RIHP and Na(+) excretion responses to acute graded volume expansion with isotonic saline were quantified under ...

In this paper we address the problem of optimizing the evaluation of boolean expressions in the context of object-oriented data modelling. We develop a new heuristic for optimizing the evaluation sequence of boolean expressions based on selectivity and cost estimates of the terms constituting the boolean expression. The quality and e ciency of the heuristic is evaluated based on a quantitative ...
