Abstract
Vaccination is a strategy for mitigating the impact of coronavirus disease 2019 (COVID-19) at both the individual and population levels. Vaccine hesitancy is identified as a significant threat to global health by the World Health Organization (WHO). Vaccine hesitancy has been theorized as a continuum encompassing a range of attitudes, beliefs, emotional orientations, ideologies, and health-seeking behaviors. Individuals who received the COVID-19 vaccine but also indicated some level of hesitancy about vaccination, or "hesitant adopters," remain an understudied group. This study uses a qualitative descriptive design to understand motivations to receive the COVID-19 vaccine among hesitant adopters at various self-reported levels of hesitancy. We conducted interviews with hesitant adopters (n = 49) to analyze the elements of vaccine hesitancy corresponding to reported levels of COVID-19 vaccine hesitancy (i.e., "little hesitant," "somewhat hesitant," and "very hesitant"). Concerns about side effects are shared across the continuum but are articulated differently at each level of hesitancy. The "little hesitant" relate fears of side effects to their health and a lack of clear information to inform their health decision making, whereas the "very hesitant" articulate the risks of side effects within the frame of conspiracies related to the development, approval, and economics of the COVID-19 vaccine. Additionally, conspiracy theories generally increase in salience across the continuum, with the "very hesitant" reporting conspiracy theories as the most salient element of vaccine hesitancy. This research presents opportunities for developing targeted interventions for different levels of vaccine hesitancy.

Abstract
Disaster survivors may experience a range of mental health reactions that can include posttraumatic stress (PTS) and posttraumatic growth (PTG). The current study examines the associations between citizen disaster communication, PTS, and PTG among individuals in North Carolina communities impacted by Hurricane Matthew, approximately six weeks following the event. Participants who communicated more frequently following the hurricane exhibited more PTS and PTG. Communication activities focused on connecting with loved ones and cognitively restructuring the disaster experience were associated with PTS and PTG, whereas communication activities confirming disaster reports and assisting with disaster recovery were associated solely with PTG. Results illustrate the need for robust disaster communication ecologies to facilitate public disaster mental health response and coordination.

Abstract
BACKGROUND Helicoverpa armigera and Helicoverpa zea are major caterpillar pests of Old and New World agriculture, respectively. Both, particularly H. armigera, are extremely polyphagous, and H. armigera has developed resistance to many insecticides. Here we use comparative genomics, transcriptomics and resequencing to elucidate the genetic basis for their properties as pests. RESULTS We find that, prior to their divergence about 1.5 Mya, the H. armigera/H. zea lineage had accumulated up to more than 100 more members of specific detoxification and digestion gene families and more than 100 extra gustatory receptor genes, compared to other lepidopterans with narrower host ranges. The two genomes remain very similar in gene content and order, but H. armigera is more polymorphic overall, and H. zea has lost several detoxification genes, as well as about 50 gustatory receptor genes. It also lacks certain genes and alleles conferring insecticide resistance found in H. armigera. Non-synonymous sites in the expanded gene families above are rapidly diverging, both between paralogues and between orthologues in the two species. Whole genome transcriptomic analyses of H. armigera larvae show widely divergent responses to different host plants, including responses among many of the duplicated detoxification and digestion genes. CONCLUSIONS The extreme polyphagy of the two heliothines is associated with extensive amplification and neofunctionalisation of genes involved in host finding and use, coupled with versatile transcriptional responses on different hosts. H. armigera's invasion of the Americas in recent years means that hybridisation could generate populations that are both locally adapted and insecticide resistant.

Abstract
Polysaccharide contaminants in plasmid DNA, including current good manufacturing practices (cGMP) clinical preparations, must be removed to provide the greatest safety and efficacy for use in gene therapy and other clinical applications. We developed assays and methods for the detection and removal of these polysaccharides, our Super Clean DNA (SC-DNA) process, and have shown that these contaminants in plasmid DNA preparations are responsible for toxicity observed post-injection in animals. Furthermore, these contaminants limit the efficacy of low and high doses of plasmid DNA administered by numerous delivery routes. In particular, colanic acid (CA) that is mainly long-chained, branched and has high molecular weight (MW) is most refractory when complexed to cationic delivery vehicles and injected intravenously (IV). Because CA is often extremely large and tightly intertwined with DNA, it must be degraded, in order, to be effectively removed. We have produced a recombinant, truncated colanic acid degrading enzyme (CAE) that successfully accomplishes this task. Initially, we isolated a newly identified CAE from a bacteriophage that required truncation for proper folding while retaining its full enzymatic activity during production. Any plasmid DNA preparation can be digested with CAE and further purified, providing a critical advance to non-viral gene therapy.

Abstract
The completed draft version of the human genome, comprised of multiple short contigs encompassing 85% or more of euchromatin, was announced in June of 2000 (ref. 1). The detailed findings of the sequencing consortium were reported several months later. The draft sequence has provided insight into global characteristics, such as the total number of genes and a more accurate definition of gene families. Also of importance are genome positional details such as local genome architecture, regional gene density and the location of transcribed units that are critical for disease gene identification. We carried out a series of mapping and computational experiments using a nonredundant collection of 925 expressed sequence tags (ESTs) and sections of the public draft genome sequence that were available at different timepoints between April 2000 and April 2001. We found discrepancies in both the reported coverage of the human genome and the accuracy of mapping of genomic clones, suggesting some limitations of the draft genome sequence in providing accurate positional information and detailed characterization of chromosomal subregions.

Abstract
The fly Drosophila melanogaster is one of the most intensively studied organisms in biology and serves as a model system for the investigation of many developmental and cellular processes common to higher eukaryotes, including humans. We have determined the nucleotide sequence of nearly all of the approximately 120-megabase euchromatic portion of the Drosophila genome using a whole-genome shotgun sequencing strategy supported by extensive clone-based sequence and a high-quality bacterial artificial chromosome physical map. Efforts are under way to close the remaining gaps; however, the sequence is of sufficient accuracy and contiguity to be declared substantially complete and to support an initial analysis of genome structure and preliminary gene annotation and interpretation. The genome encodes approximately 13,600 genes, somewhat fewer than the smaller Caenorhabditis elegans genome, but with comparable functional diversity.

Abstract
A total of 100 kb of DNA derived from 69 individual human brain cDNA clones of 0.7-2.0 kb were sequenced by concatenated cDNA sequencing (CCS), whereby multiple individual DNA fragments are sequenced simultaneously in a single shotgun library. The method yielded accurate sequences and a similar efficiency compared with other shotgun libraries constructed from single DNA fragments (> 20 kb). Computer analyses were carried out on 65 cDNA clone sequences and their corresponding end sequences to examine both nucleic acid and amino acid sequence similarities in the databases. Thirty-seven clones revealed no DNA database matches, 12 clones generated exact matches (> or = 98% identity), and 16 clones generated nonexact matches (57%-97% identity) to either known human or other species genes. Of those 28 matched clones, 8 had corresponding end sequences that failed to identify similarities. In a protein similarity search, 27 clone sequences displayed significant matches, whereas only 20 of the end sequences had matches to known protein sequences. Our data indicate that full-length cDNA insert sequences provide significantly more nucleic acid and protein sequence similarity matches than expressed sequence tags (ESTs) for database searching.

Abstract
The X-linked developmental mouse mutations bare patches (Bpa) and striated (Str) may be homologous to human X-linked dominant chondrodysplasia punctata (CDPX2) and incontinentia pigmenti (IP2), respectively, based on their genetic mapping and clinical phenotypes. Bpa and Str have been localized to an overlapping critical region of 600 kb that demonstrates conserved gene order with loci in human Xq28 between DXS1104 and DXS52. As part of efforts to isolate the genes involved in these disorders, we have begun to develop a comparative transcription map spanning this region in both species. Using techniques of cross-species conservation and hybridization, exon trapping, and cDNA selection we have identified four known genes or members of gene families--caltractin, a member of the gamma-aminobutyric acid (GABAA) receptor gene family, a member of the melanoma antigen gene (MAGE) family, and several members of the murine-specific, X-linked lymphocyte regulated gene (Xlr3) family. Trapped exons and, in some cases, longer cDNAs have been isolated for potentially 7-9 additional genes. One cDNA demonstrates highly significant homology with members of the Krüppel family of zinc finger transcription factors. A second novel cDNA demonstrates homology at the 3' end of the predicted amino acid sequence to a LIM domain consensus. Gene order appears conserved among those cDNAs determined to be present in both human and mouse. Three of the murine transcripts appear to be present in multiple copies within the Bpa/Str critical region and could be associated with a predisposition to genomic rearrangements. Reverse transcriptase PCR (RT-PCR) and Northern analysis demonstrate that several of the transcripts are expressed in mid-gestation murine embryos and neonatal skin, making them candidates for the Bpa and Str mutations and their respective homologous human disorders.

Abstract
The BCM Search Launcher is an integrated set of World Wide Web (WWW) pages that organize molecular biology-related search and analysis services available on the WWW by function, and provide a single point of entry for related searches. The Protein Sequence Search Page, for example, provides a single sequence entry form for submitting sequences to WWW servers that offer remote access to a variety of different protein sequence search tools, including BLAST, FASTA, Smith-Waterman, BEAUTY, PROSITE, and BLOCKS searches. Other Launch pages provide access to (1) nucleic acid sequence searches, (2) multiple and pair-wise sequence alignments, (3) gene feature searches, (4) protein secondary structure prediction, and (5) miscellaneous sequence utilities (e.g., six-frame translation). The BCM Search Launcher also provides a mechanism to extend the utility of other WWW services by adding supplementary hypertext links to results returned by remote servers. For example, links to the NCBI's Entrez data base and to the Sequence Retrieval System (SRS) are added to search results returned by the NCBI's WWW BLAST server. These links provide easy access to auxiliary information, such as Medline abstracts, that can be extremely helpful when analyzing BLAST data base hits. For new or infrequent users of sequence data base search tools, we have preset the default search parameters to provide the most informative first-pass sequence analysis possible. We have also developed a batch client interface for Unix and Macintosh computers that allows multiple input sequences to be searched automatically as a background task, with the results returned as individual HTML documents directly to the user's system. The BCM Search Launcher and batch client are available on the WWW at URL http:@gc.bcm.tmc.edu:8088/search-launcher.html.

Abstract
BEAUTY (BLAST enhanced alignment utility) is an enhanced version of the NCBI's BLAST data base search tool that facilitates identification of the functions of matched sequences. We have created new data bases of conserved regions and functional domains for protein sequences in NCBI's Entrez data base, and BEAUTY allows this information to be incorporated directly into BLAST search results. A Conserved Regions Data Base, containing the locations of conserved regions within Entrez protein sequences, was constructed by (1) clustering the entire data base into families, (2) aligning each family using our PIMA multiple sequence alignment program, and (3) scanning the multiple alignments to locate the conserved regions within each aligned sequence. A separate Annotated Domains Data Base was constructed by extracting the locations of all annotated domains and sites from sequences represented in the Entrez, PROSITE, BLOCKS, and PRINTS data bases. BEAUTY performs a BLAST search of those Entrez sequences with conserved regions and/or annotated domains. BEAUTY then uses the information from the Conserved Regions and Annotated Domains data bases to generate, for each matched sequence, a schematic display that allows one to directly compare the relative locations of (1) the conserved regions, (2) annotated domains and sites, and (3) the locally aligned regions matched in the BLAST search. In addition, BEAUTY search results include World-Wide Web hypertext links to a number of external data bases that provide a variety of additional types of information on the function of matched sequences. This convenient integration of protein families, conserved regions, annotated domains, alignment displays, and World-Wide Web resources greatly enhances the biological informativeness of sequence similarity searches. BEAUTY searches can be performed remotely on our system using the "BCM Search Launcher" World-Wide Web pages (URL is < http:/ /gc.bcm.tmc.edu:8088/ search-launcher/launcher.html > ).

Abstract
Diagnosis of X-chromosomal microdeletions has relied upon the traditional methods of Southern blotting and DNA amplification, with carrier identification requiring time-consuming and unreliable dosage calculations. In this report, we describe rapid molecular cytogenetic identification of deleted DNA in affected males with the Xp21 contiguous gene syndrome (complex glycerol kinase deficiency, CGKD) and female carriers for this disorder. CGKD deletions involve the genes for glycerol kinase, Duchenne muscular dystrophy, and/or adrenal hypoplasia congenita. We report an improved method for diagnosis of deletions in individuals with CGKD and for identification of female carriers within their families, using fluorescence in situ hybridization (FISH) with a cosmid marker (cosmid 35) within the glycerol kinase gene. When used in combination with an Xq control probe, affected males demonstrate a single signal from the control probe, while female carriers demonstrate a normal chromosome with two signals, as well as a deleted chromosome with a single signal from the control probe. FISH analysis for CGKD provides the advantages of speed and accuracy for evaluation of submicroscopic X-chromosomal deletions, particularly in identification of female carriers. In addition to improving carrier evaluation, FISH will make prenatal diagnosis of CGKD more readily available.

Abstract
In a sequence database search using the human glycerol kinase-encoding sequence (HUMGLYKINB) as a query, we identified six previously unidentified carbohydrate kinase sequences. Five of the six newly identified sequences appear to be known types of carbohydrate kinases, four are glycerol kinases and one is a gluconokinase. The sixth newly identified sequence, the Caenorhabditis elegans gene, CER08D7.7-CEF59B2.1, shows similarity to the family of carbohydrate kinases including other glycerol kinases, xylulokinases, gluconokinases, ribulokinases, rhamnulokinases, and fucokinases. A phylogenetic comparison of this newly identified Caenorhabditis elegans gene with the other members of the carbohydrate kinase family demonstrated that this sequence cannot be assigned to one of the known classes of carbohydrate kinases.

Abstract
Male to female sex reversal has been observed in individuals with duplications of the short arm of the X chromosome. Here we demonstrate that sex reversal results from the presence of two active copies of an Xp locus rather than from its rearrangement and that alterations at this locus constitute one of the causes of sex reversal in individuals with a normal 46,XY karyotype. We have named this locus DSS (Dosage Sensitive Sex reversal) and localized it to a 160 kilobase region of chromosome Xp21, adjacent to the adrenal hypoplasia congenita locus. The identification of male individuals deleted for DSS suggests that this locus is not required for testis differentiation. We propose that DSS has a role in ovarian development and/or functions as a link between ovary and testis formation.

Abstract
The adrenal hypoplasia congenita (AHC) and glycerol kinase (GK) loci are telomeric to the Duchenne muscular dystrophy locus in Xp21. We developed a pair of yeast artificial chromosome (YAC) contigs spanning at least 1.2 Mb and encompassing the region from the telomeric end of the Duchenne muscular dystrophy (DMD) locus to beyond YHX39 (DXS727), including the genes for AHC and GK. The centromeric contig consists of 13 YACs reaching more than 600 kb from DMD through GK. The telomeric contig group consists of 8 YACs containing more than 600 kb including the markers YHX39 (DXS727) and QST-59 (DXS319). Patient deletion breakpoints in the region of the two YAC contigs define at least eight intervals, and seven deletion breakpoints are contained within these contigs. In addition to the probes developed from YAC ends, we have mapped eight Alu-PCR probes amplified from a radiation-reduced somatic cell hybrid, two anonymous DNA probes, and one Alu-PCR product amplified from a cosmid end, for a total of 26 new markers within this region of 2 Mb or less. One YAC in the centromeric contig contains an insert encompassing the minimum interval for GK deficiency defined by patient deletion breakpoints, and this clone includes all or part of the GK gene.

Abstract
Characterization of Xp21 distal to Duchenne muscular dystrophy (DMD) in the region containing the genes for adrenal hypoplasia congenita (AHC) and glycerol kinase deficiency (GKD) has been limited due to a paucity of probes. Two probes were localized between DXS28 (C7) and AHC, the yeast artificial chromosome insert YHX39 (DXS727) and the polymorphic phage clone QST59 (DXS319). A genomic clone, FT1 (DXS726), 3' to DMD, was also characterized. Portions of the three probes were sequenced and primer pairs were generated to amplify a sequence-tagged site within each probe. Amplification of DNA from patients confirmed the deletion results obtained by Southern blot analysis, and these three sequence-tagged sites were successfully combined for triplex PCR. In addition to facilitating molecular genetic diagnosis in Xp21, these probes can be used to identify additional YACs and other probes to further increase the genomic information and diagnostic capabilities in this region.

Abstract
Hexokinase 1 (HK1) is one of four mammalian HK isoenzymes and maps to human chromosome 10. Two yeast artificial chromosomes (YACs) were identified in the Washington University human YAC library using polymerase chain reaction (PCR) primers designed with knowledge of the human HK1 cDNA sequence. YAC B129B12 is 120 kb in length and maps entirely to chromosome 10. YAC A159D5 is 400 kb in length and appears to have resulted from a recombination of chromosome 10 with non-chromosome 10 material. We report these YACs as potential resources for those interested in HK1 gene organization and mapping, as well as those desiring additional genomic information and markers on chromosome 10.
