Abstract
PURPOSE A new high-resolution next-generation sequencing (NGS)-based method was established to type closely related European type II Toxoplasma gondii strains. METHODS T. gondii field isolates were collected from different parts of Europe and assessed by whole genome sequencing (WGS). In comparison to ME49 (a type II reference strain), highly polymorphic regions (HPRs) were identified, showing a considerable number of single nucleotide polymorphisms (SNPs). After confirmation by Sanger sequencing, 18 HPRs were used to design a primer panel for multiplex PCR to establish a multilocus Ion AmpliSeq typing method. Toxoplasma gondii isolates and T. gondii present in clinical samples were typed with the new method. The sensitivity of the method was tested with serially diluted reference DNA samples. RESULTS Among type II specimens, the method could differentiate the same number of haplotypes as the reference standard, microsatellite (MS) typing. Passages of the same isolates and specimens originating from abortion outbreaks were identified as identical. In addition, seven different genotypes, two atypical and two recombinant specimens were clearly distinguished from each other by the method. Furthermore, almost all SNPs detected by the Ion AmpliSeq method corresponded to those expected based on WGS. By testing serially diluted DNA samples, the method exhibited a similar analytical sensitivity as MS typing. CONCLUSION The new method can distinguish different T. gondii genotypes and detect intra-genotype variability among European type II T. gondii strains. Furthermore, with WGS data additional target regions can be added to the method to potentially increase typing resolution.

Abstract
Over the past decade, the rapid increase in the incidence of antibiotic-resistant bacteria has promoted research towards alternative therapeutics such as antimicrobial peptides (AMPs), but their biodegradability limits their application. Encapsulation into nanocarriers based on the self-assembly of surfactant-like lipids is emerging as a promising strategy for the improvement of AMPs' stability and their protection against degradation when in biological media. An in-depth understanding of the interactions between the structure-forming lipids and AMPs is required for the design of nanocarriers. This in silico study, demonstrates the self-assembly of the amphiphilic lipid glycerol monooleate (GMO) with the antimicrobial peptide LL-37 into nanocarriers on the molecular scale. Molecular dynamics (MD) simulations show the formation of direct micelles, with either one or two interacting LL-37, and vesicles in this two-component system in agreement with experimental results from small-angle X-ray scattering studies. The hydrophobic contacts between LL-37 and GMOs in water appear responsible for the formation of these nanoparticles. The results also suggest that the enhanced antimicrobial efficiency of LL-37 in these nanocarriers that was previously observed experimentally can be explained by the availability of its side chains with charged amino acids, an increase of the electrostatic interaction and a decrease of the peptide's conformational entropy upon interacting with GMO. The results of this study contribute to the fundamental understanding of lipid-AMP interactions and may guide the comprehensive design of lipid-based self-assembled nanocarriers for antimicrobial peptides.

Abstract
In cattle, antibodies to Toxoplasma gondii infection are frequently detected, but evidence for the presence of T. gondii tissue cysts in cattle is limited. To study the concordance between the presence of anti-T. gondii IgG and viable tissue cysts of T. gondii in cattle, serum, liver and diaphragm samples of 167 veal calves and 235 adult cattle were collected in Italy, the Netherlands, Romania and the United Kingdom. Serum samples were tested for anti-T. gondii IgG by the modified agglutination test and p30 immunoblot. Samples from liver were analyzed by mouse bioassay and PCR after trypsin digestion. In addition, all diaphragms of cattle that had tested T. gondii-positive (either in bioassay, by PCR on trypsin-digested liver or serologically by MAT) and a selection of diaphragms from cattle that had tested negative were analyzed by magnetic capture quantitative PCR (MC-PCR). Overall, 13 animals were considered positive by a direct detection method: seven out of 151 (4.6%) by MC-PCR and six out of 385 (1.6%) by bioassay, indicating the presence of viable parasites. As cattle that tested positive in the bioassay tested negative by MC-PCR and vice-versa, these results demonstrate a lack of concordance between the presence of viable parasites in liver and the detection of T. gondii DNA in diaphragm. In addition, the probability to detect T. gondii parasites or DNA in seropositive and seronegative cattle was comparable, demonstrating that serological testing by MAT or p30 immunoblot does not provide information about the presence of T. gondii parasites or DNA in cattle and therefore is not a reliable indicator of the risk for consumers.

Abstract
BACKGROUND Skin is a multilayer interface between the body and the environment, responsible for many important functions, such as temperature regulation, water transport, sensation, and protection from external triggers. OBJECTIVES This paper provides an overview of principal factors that influence human skin and describes the diversity of skin characteristics, its causes and possible consequences. It also discusses limitations in the barrier function of the skin, describing mechanisms of absorption. METHODS There are a number of in vivo investigations focusing on the diversity of human skin characteristics with reference to barrier properties and body-dependent factors. RESULTS Skin properties vary among individuals of different age, gender, ethnicity, and skin types. In addition, skin characteristics differ depending on the body site and can be influenced by the body-mass index and lifestyle. Although one of the main functions of the skin is to act as a barrier, absorption of some substances remains possible. CONCLUSIONS Various factors can alter human skin properties, which can be reflected in skin function and the quality of everyday life. Skin properties and function are strongly interlinked.

Abstract
Engineering a small diameter vascular graft with mechanical and biological properties comparable to living tissues remains challenging. Often, current devices lead to thrombosis and unsatisfactory long-term patency as a result of poor blood compatibility and a mismatch between the mechanical properties of the living tissue and the implanted biomaterial. Addressing all these requirements is essential to produce scaffolds able to survive throughout the life of the patient. For this purpose, we fabricated a novel three-layered vascular graft by combining electrospinning and braiding. Mirroring the structure of human blood vessels, the proposed device is composed of three layers: the intima, the media, and the adventitia. The intima and media layers were obtained by sequentially electrospinning silk fibroin (SF) and poly(L-lactide-co-ε-caprolactone), with ratios selected to match the mechanical properties of the native tissue. For the outer layer, the adventitia, SF yarns were braided on top of the electrospun tubes to create a structure able to withstand high pressures. Compliance, Young's modulus and deformability of the obtained scaffold were similar to that of human blood vessels. Additionally, cytocompatibility of the two layers, media and intima, was assessed in vitro by analysing cell metabolic activity and proliferation of endothelial cells and smooth muscle cells, respectively. Furthermore, heparin functionalization of the scaffolds led to improved anticoagulant properties upon incubation in whole blood. The obtained results indicate a potential application of the herewith designed three-layered construct as a vascular graft for small diameter blood vessel engineering.

Abstract
Electrospinning is a versatile method for preparing functional three-dimensional scaffolds. Synthetic and natural polymers have been used to produce micro- and nanofibers that mimic extracellular matrices. Here, we describe the use of emulsion electrospinning to prepare blended fibers capable of hosting aqueous species and releasing them in solution. The existence of an aqueous and a non-aqueous phase allows water-soluble molecules to be introduced without altering the structure and the degradation of the fibers, and means that their release properties under physiological conditions can be controlled. To demonstrate the loading capability and flexibility of the blend, various species were introduced, from magnetic nanoparticles and quantum rods to biological molecules. Cellular studies showed the spontaneous adhesion and alignment of cells along the fibers. Finally, in vivo experiments demonstrated the high biocompatibility and safety of the scaffolds up to 21 days post-implantation.

Abstract
A search is made for charged Higgs bosons predicted by Two-Higgs-Doublet extensions of the Standard Model (2HDM) using electron-positron collision data collected by the OPAL experiment at [Formula: see text], corresponding to an integrated luminosity of approximately 600 pb-1. Charged Higgs bosons are assumed to be pair-produced and to decay into [Formula: see text], τντ or AW±. No signal is observed. Model-independent limits on the charged Higgs-boson production cross section are derived by combining these results with previous searches at lower energies. Under the assumption [Formula: see text], motivated by general 2HDM type II models, excluded areas on the [Formula: see text] plane are presented and charged Higgs bosons are excluded up to a mass of 76.3 GeV at 95 % confidence level, independent of the branching ratio BR(H±→τντ ). A scan of the 2HDM type I model parameter space is performed and limits on the Higgs-boson masses [Formula: see text] and mA are presented for different choices of tanβ.

Abstract
In this work a new approach is introduced for surface properties control by laser texturing process. By UV laser irradiation, we are able to control the surface wettability of a chitosan polymeric film in which is introduced a chloroauric acid salt by immersion. Specifically the UV irradiation is responsible for the creation of gold nanoparticles at the irradiated surface of the polymeric film. This photolytic process allows us to localize and design accurately surface patterns and moreover to tune metallic particle size in the range of nanoscale. After the characterization of our gold textured surfaces by atomic force and scanning electron microscopies, we demonstrate the link between wettability surface properties and gold nanoparticles size. The experimental results indicate the influence of the laser intensity, the irradiation time and the polymer film thickness (by increasing the gold concentration) on the gold nanoparticle density and size.

Abstract
In this work we propose the evolution of a new class of optical pressure sensors suitable for robot tactile sensing. The sensors are based on a tapered optical fiber, where optical signals travel embedded into a PDMS-gold nanocomposite material. By applying different pressure forces on the PDMS-based nanocomposite we measure in real time the change of the optical transmitted intensity due to the coupling between the gold nanocomposite material and the tapered fiber region. The intensity reduction of the transmitted light intensity is correlated with the pressure force magnitude.

Abstract
The parameters characterising the trap centres involved in the thermoluminescence of KMgF3:LaF3 compounds have been found by deconvolving the glow curve with the General One Trap model (GOT). For the fitting procedure the Levenberg-Marquardt method has been employed. Tm-T(stop) measurements along with initial rise measurements were performed in order to estimate the number of peaks the glow curve is made up of, and the corresponding activation energies. Instead of the Runge-Kutta method, a novel algorithm has been employed to integrate the differential equation of the GOT model, which reduces the computational time nearly 30 times with respect to the former when the glow curve is recorded with a lineal heating rate profile. The strong computational time reduction makes feasible a large number of runs with different guess values. An interesting result is that the concentration of disconnected deep traps is much less than the concentration of trap centres.

Abstract
RATIONALE The combination of idazoxan, a specific alpha(2)-adrenoceptor antagonist with raclopride, a selective D(2)/D(3) receptor antagonist, has been recently proposed to produce an "atypical" antipsychotic profile comparable to that of clozapine, based on an animal study which analysed dopamine efflux in the medial prefrontal cortex and the preclinical test of conditioned avoidance response (CAR) for evaluation of antipsychotic potential. Accordingly, the combination of a "typical" antipsychotic with idazoxan has been proposed as an augmentation strategy in treatment-resistant schizophrenia, although its therapeutic potential remains difficult to predict. OBJECTIVES Given the momentum stimulated by these reports, the present study investigated whether the combination of idazoxan with raclopride is indeed sufficient to mimic the ability of clozapine to reverse prepulse inhibition (PPI) deficits in rats, a behavioral paradigm that models PPI deficits observed in the schizophrenia spectrum, and currently the only test which reliably appears to distinguish between "typical" antipsychotics and compounds with "atypical" antipsychotic potential. METHODS The effects of the combination idazoxan/raclopride were examined in two PPI paradigms: 1) phencyclidine (PCP)-induced disruption of PPI, which has been shown to be preferentially reversed by "atypical" antipsychotics; 2) apomorphine-induced disruption of PPI which can be reversed by either "typical" high-potency D(2) dopamine antagonists or "atypical" antipsychotics. RESULTS In contrast to clozapine, combining idazoxan with raclopride failed to reverse PCP-induced deficits in PPI. In addition, there was no evidence of an enhancing effect of idazoxan on the blockade of apomorphine-induced disruption of PPI by raclopride. CONCLUSION The present results challenge the hypothesis that simple alpha(2)/D(2) blockade is sufficient to produce clozapine-like "atypical" antipsychotic activities, and support the consensus that the PPI paradigm represents the most sophisticated behavioral preclinical test for detecting selective "atypical" profile of antipsychotics.

Abstract
We have cloned and sequenced the ribosomal internal transcribed spacer-1 (ITS1) of Cryptosporidium wrairi. Phylogenetic analysis of this region provided further support to the validity of C. wrairi as a distinct species and also to the concept that many of the genotypes recently identified within C. parvum are in fact separate species. Analysis placed the "cattle" and "mouse" genotypes of C. parvum as each other's closest relatives and C. wrairi as a sister group to these two genotypes, followed by the "human" genotype.

Abstract
The genetic polymorphism among 57 Cryptosporidium parvum isolates belonging to genotype 'C' was studied by PCR amplification and the sequencing of two microsatellite loci (ML1 and ML2). A comparative analysis of DNA sequences showed the presence of three (ML1-238, ML1-226, and ML1-220) and seven (ML2-231, ML2-229, ML2-227, ML2-213, ML2-193, ML2-191, and ML2-187) different alleles at these two loci. Alleles differed by expansions/contractions of the microsatellite repeats that generated length polymorphisms. Some alleles were found to be associated with infections of all examined hosts (calf, kid, lamb, and human), whereas others were either associated with a single host, or were geographically restricted. When considering the information from both loci, some preferential associations between alleles are apparent. These data confirm the utility of microsatellite markers for the molecular identification of C. parvum, which is of particular relevance in the investigation of the source of infection of outbreaks and single cases, as well as for genetic studies.

Abstract
The eukaryotic translation initiation factor eIF-4A is an ATP-dependent RNA helicase involved in ribosome attachment to the 5' end of mRNAs. Employing as a probe a Cryptosporidium parvum genomic amplicon encoding a partial polypeptide related to eIF-4A, we screened a C. parvum sporozoite cDNA library to clone the full length of the gene. Two complete cDNAs were characterized, Cp.F6 and Cp.F10, which consisted of 1,900 and 1,418 bp, respectively. The overlapping portions of the sequences shared 100% identity and encoded a polypeptide of 405 amino acids whose identity to known eIF-4A molecules ranged between 77 and 39%. The 2 cDNAs differed in the length of their respective 3' untranslated regions, of 577 bp in Cp.F6 and 72 bp in Cp.F10, in both of which a putative polyadenylation signal was identified. The structure of the cloned cDNAs, along with genomic Southern blot data indicating that eIF-4A is encoded by a single copy gene, strongly suggested that Cp.F6 and Cp.F10 reflect a differential 3' end processing of mRNA precursors, not observed so far in C. parvum. Northern blot analysis confirmed that the sporozoites express 2 eIF-4A mRNAs and showed that the lower molecular weight transcript is 10- to 20-fold more abundant. We also investigated the polymorphism of the eIF-4A gene and defined a novel polymerase chain reaction-restriction fragment length polymorphism marker discriminating between C. parvum isolates of genotypes 1 and 2.

Abstract
The coccidium Cryptosporidium parvum is an obligate intracellular parasite of the phylum Apicomplexa. It infects the gastrointestinal tract of humans and livestock, and represents the third major cause of diarrhoeal disease worldwide. Scarcely considered for decades due to its apparently non-pathogenic nature, C. parvum has been studied very actively over the last 15 years, after its medical relevance as a dangerous opportunistic parasite and widespread water contaminant was fully recognised. Despite the lack of an efficient in vitro culture system and appropriate animal models, significant advances have been made in this relatively short period of time towards understanding C. parvum biology, immunology, genetics and epidemiology. Until recently, very little was known about the genome of C. parvum, with even basic issues, such as the number and size of chromosomes, being the object of a certain controversy. With the advent of pulsed field gradient electrophoresis and the introduction of molecular biology techniques, the overall structure and fine organisation of the genome of C. parvum have started to be disclosed. Organised into eight chromosomes distributed in a very narrow range of molecular masses, the genome of C. parvum is one of the smallest so far described among unicellular eukaryotic organisms. Although fewer than 30 C. parvum genes have been cloned so far, information about the overall structure of the parasite genome has increased exponentially over the last 2 years. From the first karyotypic analyses to the recent development of physical maps for individual chromosomes, this review will try to describe the state-of-the-art of our knowledge on the nuclear genome of C. parvum and will discuss the available experimental evidence concerning the presence of extra-chromosomal elements.

Abstract
In this paper the authors question whether the development of a vaccine against cryptosporidiosis could be taken into consideration. The necessity and feasibility of such a vaccine for human and veterinary application is discussed. Developmental stages within the life cycle of the parasite that might act as possible targets for vaccine development are summarised, as well as the target antigens offered by molecular biology and immunology studies. Vaccination trials against cryptosporidiosis carried out so far, including the active and passive immunisation approach, are also overviewed. It seems that with respect to a Cryptosporidium vaccine two target groups can be considered: children of the developing world and neonatal ruminants. Antigens representing possible candidates for a subunit vaccine were identified based on their function, location and/or the immune response they evoke. While the active vaccination of newborn calves, lambs and goat kids has to face a number of important limitations, the passive immunisation approach, where dams were immunised to protect their progeny by colostral transfer, was proven to be a valuable alternative. Finally, a number of points of action for the near future are put forward.

Abstract
We used contour-clamped homogeneous electric field (CHEF) gel electrophoresis and Southern blot hybridization to analyze the molecular karyotype of Cryptosporidium parvum and establish the chromosomal location of 12 single copy genes. In agreement with previous studies, the molecular karyotype of C. parvum was found to consist of partially co-migrating chromosomes ranging in size from 0.97 to 1.55 Mb and segregating into five distinct electrophoretic bands. Hybridization results allowed the definition of a linkage group comprised of five distinct loci located on chromosome VI. Southern hybridization and restriction analysis of total C. parvum chromosomes or isolated chromosome VI using gene-specific probes and an oligonucleotide specific for C. parvum telomeres allowed the development of a long-range restriction map of chromosome VI.

Abstract
The Cryptosporidium ITS1, 5.8S and ITS2 rDNA regions from a number of Cryptosporidium isolates from different hosts and geographical areas were cloned and sequenced in order to investigate the extent of sequence heterogeneity between human and cattle-derived isolates from different geographical locations and also between isolates of Cryptosporidium from different hosts such as cats, pigs, mice and a koala. Calf-derived isolates from different continents were virtually identical as were human-derived isolates from the UK and Australia. Genetic differences between Cryptosporidium isolates were extensive and were in fact greater than the level of nucleotide divergence between Toxoplasma gondii and Neospora caninum rDNA sequences. Based on the sequence information derived from this study, PCR-RFLP of the ITS1 region was undertaken in order to directly amplify and genotype Cryptosporidium isolates from different hosts. This PCR-RFLP approach can now be used for molecular epidemiology studies, circumventing the need for costly sequencing and allowing a wider range of genetically different isolates to be examined.

Abstract
A number of severe diseases of medical and veterinary importance are caused by parasites of the phylum Apicomplexa. These parasites invade host cells using similar subcellular structures, organelles and molecular species. Proteins containing one or more copies of the type I repeat of human platelet thrombospondin (TSP1), are crucial components of both locomotion and invasion machinery. Members of this family have been identified in Eimeria tenella, E. maxima, Toxoplasma gondii, Cryptosporidium parvum and in all Plasmodium species so far analysed. Here, Andrea Crisanti and colleagues discuss the structure, localization and current understanding of the function of TSP family members in the invasion of target cells by apicomplexan parasites.

Abstract
The genetic analysis of oocysts recovered from the stools of humans and animals infected with Cryptosporidium parvum has consistently shown the existence of two distinct genotypes. One of the genotypes is found exclusively in some human infections, whereas the other genotype is found in human as well as in animal infections. On the basis of these observations and the results of published epidemiological studies with single polymorphic markers, the existence of two separate transmission cycles has been postulated, one exclusively anthroponotic and the other involving both animals and humans. To test this hypothesis, C. parvum isolates of different geographic and host origins were analyzed by using unlinked genetic polymorphisms. A total of 28 isolates originating from Europe, North and South America, and Australia were examined. Isolates clustered into two groups, one comprising both human and animal isolates and the other comprising isolates only of human origin. The absence of recombinant genotypes is consistent with two reproductively isolated populations within the species C. parvum.

Abstract
Genetic evidence for the occurrence of two Cryptosporidium parvum subgroups is presented. This evidence is based on restriction fragment length polymorphism analysis of several independent loci. Sequence analysis of the beta-tubulin intron revealed additional polymorphism. The stability of the genetic profiles following passage of C. parvum isolates between different hosts was investigated.

Abstract
A 298 bp region of the Cryptosporidium parvum 18S rDNA and a 390 bp region of the acetyl-CoA synthetase gene were sequenced for a range of human and animal isolates of Cryptosporidium from different geographical areas. A distinct genotype is common to isolates from cattle, sheep and goats and also an alpaca from Peru and is referred to here as the 'calf'-derived Cryptosporidium genotype. Another genotype of 'human'-derived isolates also appears to be conserved amongst human isolates although humans are also susceptible to infection with the 'calf' Cryptosporidium genotype. Mice and pigs carry genetically distinct genotypes of Cryptosporidium. Three snake isolates were also analysed, 2 of which exhibited C. muris genotypes and the third snake isolate carried a distinct 'mouse' genotype.

Abstract
The apicomplexan parasite Cryptosporidium parvum invades and multiplies primarily in the brush border cells of the intestinal mucosa causing in AIDS patients a severe diarrhoea that represents a significant contributing factor leading to death. Morphological analysis indicates that the invasion machinery of C. parvum is similar to the apical complex of other parasites of the phylum Apicomplexa. We provide here evidence indicating that C. parvum also shares with these parasites a molecule crucial for the invasion of host cells. We have cloned a 3894 bp-long C. parvum cDNA encoding a protein characterised by sequence and structural similarities with members of the thrombospondin (TSP) family previously described in apicomplexan parasites of the genera Toxoplasma, Eimeria and Plasmodium. This novel C. partum molecule, the TSP-related adhesive protein of Cryptosporidium-1 (TRAP-C1), is encoded by a single copy gene containing no introns. TRAP-C1 is localised in the apical end of C. parvum sporozoites and is structurally related to the micronemal proteins MIC2 of Toxoplasma and Etp100 of Eimeria, which are involved in host-cell attachment and/or invasion. The identification of TRAP-C1 sheds new light on the molecules possibly involved in the invasion process of intestinal cells by C. parvum. We have also analysed the sequence variation of TRAP-C1 among C. parvum isolates and in the closely related species C. wrairi.

Abstract
Cryptosporidium wrairi was isolated from guinea pigs during a spontaneous outbreak of cryptosporidiosis. Despite the morphological and antigenic similarities to C. parvum, C. wrairi displayed a different host range and site of infection and may represent a separate species or sub-species. We used the polymerase chain reaction to clone two distinct 550 bp-long DNA fragments, Wc-I and Wc-II, of the gene encoding the Cryptosporidium oocyst wall protein (COWP) of C. wrairi, which showed 98% identity to the C. parvum homologue. Within Wc-I, polymorphic Rsal restriction sites were used to develop a polymerase chain reaction-restriction fragment length polymorphism method able to distinguish C. wrairi from C. parvum and to identify two groups of C. parvum isolates differentially associated with animal and human infections.

Abstract
Molecular cloning and immunoelectron microscopy have been used to clone the full-length gene encoding Cryptosporidium parvum oocyst wall protein (COWP) and to analyse at the ultrastructural level the expression and localization of COWP during development in the gut. COWP is 1622 amino acids long, has a typical leader peptide and consists of 2 amino acidic domains each containing distinct repeated elements possibly originating from a common ancestral precursor. Electron microscopy localized COWP in a large cytoplasmic inclusion and in the wall-forming bodies of early and late macrogametes, respectively. Ultrastructural analysis of double-walled sporulating and mature oocysts indicated that COWP is selectively localized in the inner layer of the oocyst wall. This study provides the first localization at the ultrastructural level of a cloned coccidian oocyst wall protein.

Abstract
The ookinete surface protein of Plasmodium berghei Pbs21 belongs to a class of sexual stage antigens able to induce in the vertebrate host a transmission-blocking immune response. The effectors of this transmission-blocking immunity are antibody molecules directed against particular protein epitopes. The anti-Pbs21 monoclonal antibody 13.1 is known to bind a linear stretch of amino acids within the primary sequence of Pbs21 and to efficiently block the development of P. berghei in the mosquito gut. To map the 13.1 epitope along the amino acid sequence of Pbs21 we assayed the ability of 13.1 antibody to recognize, in Western blot, a series of Pbs21 deletion mutants as well as the ability of synthetic peptides to inhibit 13.1 binding to full length Pbs21. The epitope was identified within the second EGF-like domain of the Pbs21 molecule.

Abstract
Occupational doses are evaluated in different stages of the fuel cycle and in the operation of nuclear power plants. Trends in individual dose distribution and collective doses are analyzed. The most contributive working conditions to collective dose are identified and the implications of dose limit reduction recommended by the ICRP in 1990 are assessed. It is concluded that no relevant difficulties should appear in accomplishing the new recommendations except for implementation at Atucha I, a nuclear power plant designed in the 1960s. Some options to reduce individual and collective doses in this plant are analyzed. The change of fuel channels by new ones free from cobalt is essential to get effective improvement of occupational exposures.

Abstract
By computer analysis of the amino acid sequence of human interleukin-1 beta (IL-1 beta) and of the human type I IL-1 receptor (IL-1RI), we have identified two hydropathically complementary peptides (Fassina, G., Roller, P. P., Olson, A. D., Thorgeirsson, S. S., and Omichinski, J. G. (1989) J. Biol. Chem. 264, 11252-11257) capable of binding to each other. The sequence of the IL-1 beta peptide corresponds to that of residues 88-99 (loop 7 of the crystal structure of mature IL-1 beta) of mature IL-1 beta, one of the exposed and highly charged regions of the molecule. The substitution of this loop with an amino acid sequence of the same length but different hydropathic profile generates a mutant with drastically reduced binding activity to IL-1RI. In contrast, the binding affinity to the type II IL-1R (IL-1RII) is the same as that of wild type IL-1 beta. The results show that 1) loop 7 is part of the binding site of IL-1 beta to IL-1RI, but not to IL-1RII. 2) The structure of the mutant protein is not grossly altered except locally at the position of the substituted loop. 3) The substitution of amino acids by site-directed mutagenesis of the loop 7 region generates mutants with binding affinity constants slightly lower than that of wild type IL-1 beta and not comparable to that of the loop substitution analogue. 4. All mutants analyzed, including the loop substitutions, are biologically active, confirming the structural integrity of the proteins. We propose a binding site in which the cooperation of several low energy bonds extended over a wide area results in a high affinity complex between IL-1 and the type I receptor.

Abstract
The oocyst wall is one of the components that permits cryptosporidia both to survive in the environment and to retain infectivity. With the aim of identifying Cryptosporidium proteins specifically expressed at the oocyst stage, we screened lambda gt11 genomic libraries of Cryptosporidium parvum with both an oocyst antiserum and a specific genetic probe. We isolated, from distinct libraries, two overlapping clones containing an open reading frame encoding a 1,252-amino-acid polypeptide. The analysis of the deduced amino acid sequence revealed unusually high contents of cysteine, proline, and histidine. The sequence was also characterized by two distinct amino acid motifs, each repeated several times. The DNA sequences coding for the amino acid repeats showed a high frequency of synonymous mutations, a result suggesting that the repeated motifs may be functionally and/or structurally important to the parasite. Antisera and monoclonal antibodies developed against a recombinant polypeptide encompassing the first 786 amino acids revealed that the corresponding protein in C. parvum had an apparent molecular weight of 190,000. Moreover, confocal microscopy analysis with immunofluorescence indicated that the protein was localized on the oocyst wall as a uniform stain and within the oocyst itself as bright granules in close association with the residual body.

Abstract
Human genomic clones of the gene encoding lipocortin (LIP) 2 (p36) and of three pseudogenes have been isolated and characterized. The LIP2 gene is at least 40 kb long and consists of 13 exons. The three pseudogenes present typical features of retroposons and, together with the gene, probably represent the entire LIP2 multigene family. Chromosomal assignment of the four loci is proposed. The hypothesis that an ancestral unit coding for 15 to 20 amino acids may have been involved in the evolution of the gene is discussed.
