Abstract
HBV/HCV co-infection is common in HIV-1-infected prisoners. To investigate the characteristics of HIV co-infections, and to evaluate the molecular heterogeneity of HIV, HBV and HCV in prisoners, we carried-out a multicenter cross-sectional study, including 65 HIV-1-infected inmates enrolled in 5 Italian detention centers during the period 2017-2019. HIV-1 subtyping showed that 77.1% of inmates were infected with B subtype and 22.9% with non-B subtypes. Italian nationals were all infected with subtype B (93.1%), except two individuals, one infected with the recombinant form CRF72_BF1, and the other with the HIV-1 sub-subtype A6, both previously not identified in inmates of Italian nationality. Non-Italian nationals were infected with subtype B (52.6%), CRFs (36.8%) and sub-subtypes A1 and A3 (5.2%). HIV variants carrying resistance mutations to NRTI, NNRTI, PI and InSTI were found in 7 inmates, 4 of which were never exposed to the relevant classes of drugs associated with these mutations. HBV and/or HCV co-infections markers were found in 49/65 (75.4%) inmates, while 27/65 (41.5%) showed markers of both HBV and HCV coinfection. Further, Italian nationals showed a significant higher presence of HCV markers as compared to non-Italian nationals (p = 0.0001). Finally, HCV phylogenetic analysis performed in 18 inmates revealed the presence of HCV subtypes 1a, 3a, 4d (66.6%, 16.7% and 16.7%, respectively). Our data suggest the need to monitor HIV, HBV and HCV infections in prisons in order to prevent spreading of these viruses both in jails and in the general population, and to implement effective public health programs that limit the circulation of different genetic forms as well as of viral variants with mutations conferring resistance to treatment.

Abstract
Acid-sensitive ion channels (ASICs) are sodium channels partially permeable to Ca2+ ions, listed among putative targets in central nervous system (CNS) diseases in which a pH modification occurs. We targeted novel compounds able to modulate ASIC1 and to reduce the progression of ischemic brain injury. We rationally designed and synthesized several diminazene-inspired diaryl mono- and bis-guanyl hydrazones. A correlation between their predicted docking affinities for the acidic pocket (AcP site) in chicken ASIC1 and their inhibition of homo- and heteromeric hASIC1 channels in HEK-293 cells was found. Their activity on murine ASIC1a currents and their selectivity vs mASIC2a were assessed in engineered CHO-K1 cells, highlighting a limited isoform selectivity. Neuroprotective effects were confirmed in vitro, on primary rat cortical neurons exposed to oxygen-glucose deprivation followed by reoxygenation, and in vivo, in ischemic mice. Early lead 3b, showing a good selectivity for hASIC1 in human neurons, was neuroprotective against focal ischemia induced in mice.

Abstract
PCDH19 encodes for protocadherin-19 (PCDH19), a cell-adhesion molecule of the cadherin superfamily preferentially expressed in the brain. PCDH19 mutations cause a neurodevelopmental syndrome named epileptic encephalopathy, early infantile, 9 (EIEE9) characterized by seizures associated with cognitive and behavioral deficits. We recently reported that PCDH19 binds the alpha subunits of GABAA receptors (GABAARs), modulating their surface availability and miniature inhibitory postsynaptic currents (mIPSCs). Here, we investigated whether PCDH19 regulatory function on GABAARs extends to the extrasynaptic receptor pool that mediates tonic current. In fact, the latter shapes neuronal excitability and network properties at the base of information processing. By combining patch-clamp recordings in whole-cell and cell-attached configurations, we provided a functional characterization of primary hippocampal neurons from embryonic rats of either sex expressing a specific PCDH19 short hairpin (sh)RNA. We first demonstrated that PCDH19 downregulation reduces GABAAR-mediated tonic current, evaluated by current shift and baseline noise analysis. Next, by single-channel recordings, we showed that PCDH19 regulates GABAARs kinetics without altering their conductance. In particular, GABAARs of shRNA-expressing neurons preferentially exhibit brief openings at the expense of long ones, thus displaying a flickering behavior. Finally, we showed that PCDH19 downregulation reduces the rheobase and increases the frequency of action potential firing, thus indicating neuronal hyperexcitability. These findings establish PCDH19 as a critical determinant of GABAAR-mediated tonic transmission and GABAARs gating, and provide the first mechanistic insights into PCDH19-related hyperexcitability and comorbidities.

Abstract
15B3 is a monoclonal IgM antibody that selectively detects pathological aggregates of the prion protein (PrP). We report the unexpected finding that 15B3 also recognizes oligomeric but not monomeric forms of amyloid-β (Aβ)42, an aggregating peptide implicated in the pathogenesis of Alzheimer's disease (AD). The 15B3 antibody: i) inhibits the binding of synthetic Aβ42 oligomers to recombinant PrP and neuronal membranes; ii) prevents oligomer-induced membrane depolarization; iii) antagonizes the inhibitory effects of oligomers on the physiological pharyngeal contractions of the nematode Caenorhabditis elegans; and iv) counteracts the memory deficits induced by intracerebroventricular injection of Aβ42 oligomers in mice. Thus this antibody binds to pathologically relevant forms of Aβ, and offers a potential research, diagnostic, and therapeutic tool for AD.

Abstract
Full-sequence data available for Plasmodium falciparum chromosomes 2 and 3 are exploited to perform a statistical analysis of the long tracts of biased amino acid composition that characterize the vast majority of P. falciparum proteins and to make a comparison with similarly defined tracts from other simple eukaryotes. When the relatively minor subset of prevalently hydrophobic segments is discarded from the set of low-complexity segments identified by current segmentation methods in P. falciparum proteins, a good correspondence is found between prevalently hydrophilic low-complexity segments and the species-specific, rapidly diverging insertions detected by multiple-alignment procedures when sequences of bona fide homologs are available. Amino acid preferences are fairly uniform in the set of hydrophilic low-complexity segments identified in the two P. falciparum chromosomes sequenced, as well as in sequenced genes from Plasmodium berghei, but differ from those observed in Saccharomyces cerevisiae and Dictyostelium discoideum. In the two plasmodial species, amino acid frequencies do not correlate with properties such as hydrophilicity, small volume, or flexibility, which might be expected to characterize residues involved in nonglobular domains but do correlate with A-richness in codons. An effect of phenotypic selection versus neutral drift, however, is suggested by the predominance of asparagine over lysine.

Abstract
To identify conserved features in the rapidly diverging portions of a well-conserved locus, completely sequenced in Plasmodium falciparum and Plasmodium berghei, a computational method based on recurrence analysis was exploited. At the level of the genomic sequence, in both species, introns and intergenic sequences-though subject to rapid diversification-do not drift without constraints, but rather coevolve, in the sense that they maintain not only an AT-rich base composition, but also a consistent use of recurring (AT)(n) tracts. One of the two genes present in the conserved locus encodes a protein that exhibits blocks of high similarity to the first enzyme in glutathione biosynthesis (gamma-glutamylcysteine synthetase) but bears long low-complexity insertions, absent in other organisms. From an analysis of the aminoacid sequence, different constraints appear to act on the borders and on the central part of the insertions. Albeit maintaining a strong bias toward hydrophilic residues, central portions diverge more rapidly than borders, through point mutation and differential presence of entire tracts.

Abstract
Recurrence analysis provides a useful tool for the characterisation of oligonucleotide usage along genomic tracts. While coding regions are characterised by a low-recurrence regimen (except in the case of intragenic repeats) introns and intergenic regions exhibit a high density of recurring oligos, and appear to be correlated from the point of view of oligonucleotide preference. By comparing homologous loci in Plasmodium falciparum and P. berghei, it can be seen that introns and intergenic regions, though exhibiting very low sequence similarity, do not drift without constraints, but maintain a consistent use of the same oligos in the two species.

Abstract
A method is presented which allows detection of a sequence correlation effect not related to patchiness in base composition or to preferences in codon usage. Recurrence plots providing local views of oligonucleotide recurrence regimen show that introns and intergenic regions are often characterised by a highly recurrent use of oligonucleotides. By window analysis it is possible to score a long sequence for the recurrence of a given subset of oligos while filtering away the effects of short-range correlations. Long-range exploration of chromosome III from Caenorhabditis elegans reveals that consistent use of recurrent oligonucleotides in introns and intergenic regions generates a correlation effect that extends over several megabases.

Abstract
The putative gene for gamma-glutamylcysteine synthetase, the rate-limiting enzyme in glutathione biosynthesis, has been characterized both in Plasmodium berghei and Plasmodium falciparum. Protein sequence comparison between these two species reveals large conserved regions sharing more than 80% similarity, separated by less conserved portions. When the comparison is extended to known gamma-glutamylcysteine synthetases from other eukaryotes, a number of high similarity blocks are observed which may help in identifying sequence essential for protein function.

Abstract
BACKGROUND Hepatitis C Virus (HCV) non-structural protein 3 (NS3) encodes a trypsin-like serine protease that catalyzes the cleavages at the NS3/NS4A, NS4A/NS4B, NS4B/NS5A and NS5A/NS5B junctions in the viral polyprotein and that shows a preference for a cysteine as the P1 residue. RESULTS We describe here a partial model of the HCV NS3 protease which allowed us to predict the position of the secondary structure elements of the enzyme and of the residues involved in its specificity. By replacing these with the corresponding residues of Streptomyces griseus protease B1 we obtained a protease that, similar to the bacterial protein and unlike the wild-type enzyme, is able to cleave a substrate containing a phenylalanine in the P1 position. CONCLUSIONS These results confirm the reliability of our model and represent one of the few examples of redesign of a serine protease substrate specificity directed by molecular modelling.

Abstract
Non-uniform composition in telomeric repeats at the extremities of Plasmodium chromosomes was exploited in order to obtain data on intraclonal diversification of telomeric sequences, relevant for the study of telomere regeneration dynamics. Families of sibling telomeric clones were obtained from several chromosomal ends of Plasmodium berghei, and analysed so as to determine the exact points from which individual clones start to diverge. As much as 90% of the telomeric tract appears to be subject to events causing abrupt changes in the sequence of telomeric repeats. The results are compatible with the hypothesis that breakpoint probability is a continuously increasing function over the entire telomeric tract.

Abstract
Several fungi secrete lipase isozymes differing in biochemical properties and in some cases in substrate specificity. In the yeast Candida rugosa, a family of related genes encodes for multiple lipase proteins, highly homologous in sequence but partially different in the regions interacting with the substrate molecule. Analysis of these substitutions performed on the basis of multiple alignments and using a 3-D model of the enzyme, allows identification of a restricted number of amino acids possibly involved in substrate specificity of Candida lipases.

Abstract
We have built a model of the specificity pocket of the protease of hepatitis C virus on the basis of the known structures of trypsin-like serine proteases and of the conservation pattern of the protease sequences among various hepatitis C strains. The model allowed us to predict that the substrate of this protease should have a cysteine residue in position P1. This hypothesis was subsequently proved by N-terminal sequencing of two products of the protease. The success of this "blind" test increases our confidence in the overall correctness of our proposed alignment of the enzyme sequence with those of other proteases of known structure and constitutes a first step in the construction of a complete model of the viral protease domain.

Abstract
Cytotoxic necrotizing factors (CNFs) are dermonecrotic protein toxins produced by human and animal clinical isolates of Escherichia coli. In this study, the CNF1 determinant was isolated and sequenced, showing that expression of biologically active toxin is governed by a unique open reading frame encoding a protein of 1,014 amino acids with a predicted molecular mass of 113.7 kDa. Nucleotide and protein data base searches showed significant homology between CNF1 and the dermonecrotic toxin of Pasteurella multocida. In particular, the two toxins were found to share a hydrophobic region of about 220 amino acids which is a potential membrane-spanning domain.

Abstract
We have implemented a system for creating and maintaining nucleotide and amino acid sequence databases especially suited for the handling of phage library-derived sequences. The system is currently used in our laboratory and has already proven to be useful for the comparison of sequences obtained by different investigators. We believe that the availability of this system will encourage and simplify the exchange of sequence data among different laboratories.

Abstract
We propose a structural model of Candida cylindracea lipase (CCL) based on the reported X-ray structure of the highly homologous Geotrichum candidum lipase (GCL). The network of interactions around the active site, the salt and disulfide bridge pattern is conserved in the proposed structure. Functional, structural and evolutionary aspects of the peculiar usage of CTG codons by C. cylindracea ATCC 14830 are discussed.

Abstract
The dynamics of telomere turnover were studied in Plasmodium, whose telomeric structures consist of linear, recognisable sequences of two distinct repeats (TTTAGGG and TTCAGGG). Independent recombinant clones containing a well-defined chromosomal extremity of Plasmodium berghei, both before and after a rare insertion event took place, were obtained from clonal parasite populations and analysed. The insertion, which splits the original telomere and causes a significant reduction in the size of the telomeric structure, is shown to consist of an integer number of subtelomeric repeats typical of P.berghei, flanked on both sides by telomere-derived motifs. Analysis of the telomeric repeat sequence heterogeneity in the otherwise homogeneous populations examined, is compatible with a model in which diversification of a given telomere is driven by the occurrence of breakpoints whose frequency rapidly increases along the telomeric tract when moving in the outward direction. The breakpoints might be due either to terminal deletions followed by random serial addition of the two repeat versions, or to recombination events. The shortening/elongation mechanism is favoured against the recombination hypothesis because of the absence of higher-order patterns in the sequence of telomeric repeats.

Abstract
A simple method of sequence comparison, based on a correlation analysis of oligonucleotide frequency distributions, is here shown to be a reliable test of overall sequence similarity. The method does not involve sequence alignment procedures and permits the rapid screening of large amounts of sequence data. It identifies those sequences which deserve more careful analysis of sequence similarity at the level of resolution of the single nucleotide. It uses observed quantities only and does not involve the adoption of any theoretical model.

Abstract
A method is proposed for the automatic detection of serial periodicities in a linear sequence. Its application to DNA subtelomeric sequences from two lower eukaryotes, P.falciparum and S.cerevisiae, reveals ordered patterns organised in hierarchical periodicities, not easily recognizable by other methods. The possible implications concerning the evolution of tandemly repetitive arrays are discussed in light of a model which involves, as successive steps, random repeat modification, the fusion of differently modified repeat versions into longer units, and the amplification of (and/or homogenization to) the more recent repeat units.
