Abstract: Imiquimod 5% cream, an immune response modifier capable of inducing IFN-α, TNF-α, and interleukins 1, 6, and 8. It was approved for use in the management of genital and perianal warts and soon embraced as a method to diminish the recurrence of keloids postexcision. A previous meta-analysis included four studies. This meta-analysis is part of a larger systematic review project on the effect of moisturizers on scars. It was conducted following an a priori protocol and the guidance of the Joanna Briggs Institute. Databases searched included PubMed, CINAHL, Embase, and Web of Science. After screening and critical appraisal, subgroup meta-analysis on excision method and location of the keloid was conducted using the Miller approach for proportional meta-analysis and a random effects model. Seven studies, including 77 participants and 82 keloids were included. Meta-analysis revealed a recurrence rate of 39% (95% CI = 8.474.4% I

Abstract: The objective of this review is to examine the reliability and measurement error of devices that measure transepidermal water loss (TEWL). TEWL is a physiological property of skin which increases when the epidermis is damaged. It is, therefore, a commonly utilised measure of skin barrier integrity. Devices measuring TEWL are available as open, semi-open or closed chamber. Studies of reliability examine the consistency of measurement, and/or responsiveness whereas measurement error scores in absolute terms the amount of error due to sources of variation. Studies examining the reliability and/or measurement error of TEWL measurement devices were included. Studies that only report on measurement of TEWL outcomes without examination of reliability and/or measurement error were excluded. The search strategy aimed to locate published and unpublished studies. Databases searched included PubMed, Embase, CINAHL and Web of Science, utilising identified keywords and limited to studies in English. Grey literature sources were searched to identify any unpublished documents. Study selection using the inclusion criteria was then assessed by two reviewers for methodological quality utilising the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) risk of bias tool to assess the reliability and measurement error of outcome measurement instruments. A total of 22 devices were examined in the 38 included studies. The quality of study design was on average rated as 'Adequate' however reliability and measurement error statistical methods were on average rated as 'Doubtful'. TEWL measurement devices were found to demonstrate good reliability and frequently correlated with other devices. However, measurement error was highly variable but improves under in vitro conditions. Future research should consider risk of bias factors when designing studies.

Abstract: Scar management is a recognised key component of rehabilitation following burn. Moisturising often combined with massage is commenced once healing tissue has gained sufficient strength to tolerate surface friction, with the aim being to hydrate the dry scar. The studies on various moisturisers and creams provide some guidance on moisturiser selection, but many are inconclusive. This survey aimed to determine the current expert opinion regarding moisturiser recommendations, including the basis for these recommendations, across the burns community. A brief web-based survey was distributed to burn therapists via mailing lists of the Australian and New Zealand Burn Association (ANZBA), and American Burn Association (ABA) 'Occupational and Physical Therapist Burn Special Interest Group'. The fifty three respondents indicated that there were 29 different moisturisers commonly recommended in practice. Three main themes were indicated as influencing recommendations for moisturiser: the perceived effects on the scar/skin (48%) the general properties of the moisturiser (38%) the ingredients (14%). Therapists reported that the principle stimuli determining their recommendations were patient feedback and the choice of the previous burn therapist in their service. Many were also guided by medical staff, pharmacists and sales representatives. Only three respondents were able to provide citations for published evidence supporting their recommendations. There is a paucity of evidence currently to support optimal moisturiser choice. This survey demonstrates that conflicting opinions are held on the ideal moisturiser brand, properties and ingredients. The recommendations made are based on low level evidence. Further research is required to inform clinicians which moisturiser to recommend to their clients. An ideal moisturiser should be one that is conducive to scar maturation, non- or minimally irritant, prevent skin drying, minimise transepidermal water loss and have no negative effect on barrier function.

Abstract: The objectives of the review are to identify the effect of any moisturizers or creams (medicated or unmedicated) on immature scars (linear, keloid or hypertrophic) on any persons of any age. Effects will be assessed by changes in scar activity, changes in the final appearance/cosmesis of the scar, improvements in patient reported features of scars (e.g. itch, tightness, range of movement) and/or by altering measurable features of the scar such as vascularity, color, height, length, pliability and/or transepidermal water loss. Specifically the review question is: are moisturizers or creams effective in modifying immature scars?

Abstract: Imprinted genes display biased expression of paternal and maternal alleles in mammals. They are marked through epigenetic process during gametogenesis. Characterization of imprinted genes has expanded our understanding of the regulation and function of genes. In the current study, 22 experimentally validated imprinted genes in bovine (Bos Taurus) were analysed. Several supervised machine learning algorithms and attribute weighting methods were used to find characteristics of different types of imprinted genes and suggest a classification method for finding maternally and paternally expressed genes in bovine. For assessing the best model and comparing attributes in other organisms, we have also conducted a comparative analysis for human and sheep imprinted genes. According to the results of the present study, GC contents 10 and 100 kb upstream, Gly and Gln amino acids, Ile/ATC codon usage, LINE and SINE in 100kbup and length of first intron were significantly different between the maternal and paternal genes in cattle. Considering all species together, we found that GC content 100 kb up, LINE 100 kb up and the frequency of amino acids like Gly, Gln and Met were the most important attributes for identifying the paternal and maternal imprinted genes. These findings could imply conservation pattern in the attributes among these species.

Abstract: The common mantra with which patients often leave a burns unit is "moisturize and massage". Various products have been reported for use in practice including aqueous cream BP, bees wax and herbal oil creams, silicone based creams, paraffin etroleum/mineral oil based products and aloe vera gels. Often combined with other scar management techniques such as pressure therapy, massage and contact media, moisturizers convey active properties of their own. To date no published review on the optimal moisturizer for burn scar management has been identified via searches of recognized databases. The objective of this review was to identify and synthesize the best available evidence on the effectiveness of moisturizer use in the management of active burn scars following burn injury. More specifically, this review focused on the following questions: Does moisturizer use have an effect on scar outcomes following burn injury, including scar formation, skin breakdown, patient acceptance and water loss? What is the optimal base composition of moisturizers used in scar management for patients who have sustained a burn injury? Types of participants: Patients of any age who have sustained a burn injury of any size, and have been admitted to a hospital or regional burn unit or burn centre for the management of their injury. Types of intervention(s) henomena of interest: Studies evaluating moisturizer applied to healed skin following burn injury were considered for inclusion. Moisturizer may have been compared to usual care as defined by the in idual study, other interventions, or a different type of moisturizer. Studies comparing moisturizer and massage compared to moisturizer alone were excluded. Types of studies: This review primarily considered experimental study designs, including randomized and pseudo-randomized controlled trials. Types of outcomes: Primary outcomes for examination in this review included scar formation and skin breakdown, measured by objective tools or subjective scales. Secondary outcomes included product acceptance, patient compliance and transepidermal water loss. A search was conducted to identify published and unpublished studies via electronic databases. Reference lists of all papers selected for full text retrieval were then hand searched for potential additional citations. Articles meeting pre-determined eligibility criteria for the review were assessed by two independent reviewers using standardized checklists from the Joanna Briggs Institute Meta Analysis of Statistics Assessment and Review Instrument. Corresponding authors were contacted where additional information was required however this strategy did not yield additional information that altered study eligibility status. Data was extracted from the included paper using the standardized data extraction tool from the Joanna Briggs Institute Meta Analysis of Statistics Assessment and Review Instrument. Narrative synthesis of the included study was undertaken. One study, following a randomized controlled design, was eligible for inclusion in this review. This study investigated the effect of vitamin E cream versus a base moisturizing cream on outcomes including range of motion, scar thickness, cosmetic appearance and graft size. No significant differences between groups for all reported outcomes were observed. Despite the common practice involving moisturizers TRUNCATED AT 500 WORDS.

Abstract: 1. The objective of the study was to investigate the influence of maternal and parent of origin effects (POE) on genetic variation of Iranian native fowl on economic traits. 2. Studied traits were body weights at birth (BW0), at eight (BW8) and 12 weeks of age (BW12), age (ASM) and weight at sexual maturity (WSM), egg number (EN) and average egg weight (AEW). 3. Several models, including additive, maternal additive genetics, permanent environmental effects and POE were compared using Wombat software. Bayesian Information Criterion (BIC) was used to identify the best model for each trait. The chance of reranking of birds between models was investigated using Spearman correlation and Wilcoxon rank test. 4. Based on the best model, direct heritability estimates for BW0, BW8, BW12, ASM, WSM, EN and AEW traits were 0.05, 0.21, 0.23, 0.30, 0.39, 0.22 and 0.38, respectively. Proportion of variance due to paternal POE for BW8 was 4% and proportion of variance due to maternal POE for BW12 was 5%. 5. Estimated maternal heritability for BW0 was 0.30 and for BW8 and BW12 were 0.00 and 0.01, respectively, which shows that maternal heritability was reduced by age. 6. Based on the results, considering POE for BW8 and BW12 and maternal genetic effects for BW0 improved the accuracy of estimations and avoid reranking of birds for these traits.
