PROTOGIM: a novel tool to search motifs and domains in hypothetical proteins of protozoan genomes.
Whole sequencing of protozoan trypanosomatid genomes revealed the presence of several predicted unknown genes coding for hypothetical proteins. Pairwise, alignment-based, computational methods available online are unable to identify the function of these sequences. To detect clues to identify the function of hypothetical proteins, a user-friendly, bioinformatic tool named PROTOzoan Gene Identification Motifs (PROTOGIM, available on http://www.biowebdb.org/protogim ) was developed, which allows the user to search functional patterns of hypothetical proteins through the screening of regular expression in the sequences. The analysis of 1,194 trypanosomatid hypothetical proteins through PROTOGIM resulted in an identification of motifs and domains in 98% of the cases, demonstrating the reliability and accuracy of the employed method. The added value of this tool is the possibility to modify or insert new regular expressions to perform an analysis against either one or several sequences at the same time. An in silico strategy along with biochemical and molecular characterizations creates new possibilities to find the functions of hypothetical proteins at the postgenome era
Smoking cessation interventions for Hispanic/Latino(a) adults in the USA: protocol for a systematic review and planned meta-analysis
Introduction Hispanic smokers face multiple cultural and socioeconomic barriers to cessation that lead to prominent health disparities, including a lack of language-appropriate, culturally relevant, evidence-based smoking cessation interventions. This systematic review will examine the literature on smoking cessation interventions for Hispanic adults in the USA to assess (1) the availability of interventions, (2) the methodological quality of the studies evaluating the interventions and (3) the efficacy of the interventions.Methods and analysis A systematic literature search will be conducted, in English with no date limits, through the following databases starting at year of inception: Medical Allied Health Literature, Embase, American Psychology Association Psychology Articles, Cumulative Index to Nursing and Allied Health Literature Complete, ScienceDirect, Health & Medicine Collection and Web of Science Core Collection. Trial registries and grey literature sources will be searched to identify ongoing or unpublished studies. Literature search will be rerun prior to eventual submission of the review to ensure the inclusion of relevant studies. Quantitative studies evaluating the efficacy of a smoking cessation intervention (ie, smoking cessation as a measured outcome) for Hispanic adult smokers in the USA will be included in the systematic review. Two authors will independently identify relevant studies, extract data and conduct quality and risk of bias assessments. Discrepancies in coding will be discussed between the two reviewers and pending disagreements will be resolved by a third reviewer. First, the quality of all studies will be assessed, then randomised controlled trials (RCTs) will be further evaluated for risk of bias using Cochraneβs Risk of Bias Tool. All eligible studies will be summarised descriptively. If data allow, the efficacy of smoking cessation interventions tested in RCTs, with a minimum follow-up of 6 months, will be quantitatively estimated using ORs and 95% CIs. The association between intervention type/modality and efficacy will be assessed via subgroup analyses.PROSPERO registration number CRD42022291068
