Precision Rhinoplasty Cylindric Burrs-Sidewall Aesthetics.

The development of power instruments has led to great advances in rhinoplasty. It has helped to reduce operating time, minimize damage to the surrounding soft tissues, and allow precision bony modification compared with the use of manual rasps. Burrs help ensure precise results by (i) creating a smooth transition between the lateral nasal sidewall and the face, (ii) treating bony asymmetries, and (iii) producing homogeneous upper and middle thirds that softy translate into the upper lateral cartilages. The aim of this paper is to show applications of cylindrical burrs in rhinoplasty surgery to treat the dorsal upper and middle thirds as well as lateral sidewalls of the nose, regardless of whether the dorsal preservation or structure technique is used. This approach offers a safe, fast, and precise technique that can be used in conjunction with piezo osteotomy to obtain the optimal outcomes.

Evaluation of genetic diversity using iPBS-SCoT marker methods in native hawthorn genetic resources and species identification by using DNA barcoding method.

Hawthorn is an important medicinal plant that spreads around the world and is used in traditional Chinese medicine. Its flowers and leaves contain flavonoids, vitamins, organic acids and essential oils. Its fruit is consumed as fresh and dried and is an important plant for human health. In this study, iPBS (Inter Primer Binding Site) and SCoT (Start Codon Target Polymorphism) markers were used to analyze genetic variation among 101 hawthorn genotypes collected from Çoruh Valley, Türkiye and ITS markers were used for DNA barcoding.  Ten iPBS primers were used and a total of 400 alleles were identified from ten iPBS primers with an average of 40 alleles. PIC values ranged from 0.239 (iPBS 2387) to 0.272 (iPBS 2244). Twenty SCoT primers were used and have an average of 50.05 alleles. The PIC values of the primers ranged from 0.251 (SCoT 2) to 0.297 (SCoT 34). For the DNA barcoding study, it was confirmed that the correct region was amplified and sequenced. The genotypes we used in the study matched 14 different accession numbers by searching a BLASTN in the NCBI. NCBI similarity rates of hawthorn genotypes are between 90.83% and 100%. The study emphasizes the genetic diversity of hawthorn grown from seed and the importance of preserving plant genetic resources.

Subgroups of Idiopathic Clubfoot Can Predict Short-term Outcomes.

BACKGROUND: The Pirani scale is used for the assessment of Ponseti-managed clubfoot. Predicting outcomes using the total Pirani scale score has varied results, however, the prognostic value of midfoot and hindfoot components remains unknown. The purpose was to (1) determine the existence of subgroups of Ponseti-managed idiopathic clubfoot based on the trajectory of change in midfoot and hindfoot Pirani scale scores, (2) identify time points, at which subgroups can be distinguished, and (3) determine whether subgroups are associated with the number of casts required for correction and need for Achilles tenotomy. METHODS: Medical records of 226 children with 335 idiopathic clubfeet, over a 12-year period, were reviewed. Group-based trajectory modeling of the Pirani scale midfoot score and hindfoot score identified subgroups of clubfoot that followed statistically distinct patterns of change during initial Ponseti management. Generalized estimating equations determined the time point, at which subgroups could be distinguished. Comparisons between groups were determined using the Kruskal-Wallis test for the number of casts required for correction and binary logistic regression analysis for the need for tenotomy. RESULTS: Four subgroups were identified based on the rate of midfoot-hindfoot change: (1) fast-steady (61%), (2) steady-steady (19%), (3) fast-nil (7%), and (4) steady-nil (14%). The fast-steady subgroup can be distinguished at the removal of the second cast and all other subgroups can be distinguished at the removal of the fourth cast [ H (3) = 228.76, P < 0.001]. There was a significant statistical, not clinical, difference in the total number of casts required for correction across the 4 subgroups [median number of casts 5 to 6 in all groups, H (3) = 43.82, P < 0.001]. Need for tenotomy was significantly less in the fast-steady (51%) subgroup compared with the steady-steady (80%) subgroup [ H (1) = 16.23, P < 0.001]; tenotomy rates did not differ between the fast-nil (91%) and steady-nil (100%) subgroups [ H (1) = 4.13, P = 0.04]. CONCLUSIONS: Four distinct subgroups of idiopathic clubfoot were identified. Tenotomy rate differs between the subgroups highlighting the clinical benefit of subgrouping to predict outcomes in Ponseti-managed idiopathic clubfoot. LEVEL OF EVIDENCE: Level II, prognostic.

Characterization of Two-Component System gene (TCS) in melatonin-treated common bean under salt and drought stress.

The two-component system (TCS) generally consists of three elements, namely the histidine kinase (HK), response regulator (RR), and histidine phosphotransfer (HP) gene families. This study aimed to assess the expression of TCS genes in P. vulgaris leaf tissue under salt and drought stress and perform a genome-wide analysis of TCS gene family members using bioinformatics methods. This study identified 67 PvTCS genes, including 10 PvHP, 38 PvRR, and 19 PvHK, in the bean genome. PvHK2 had the maximum number of amino acids with 1261, whilst PvHP8 had the lowest number with 87. In addition, their theoretical isoelectric points were between 4.56 (PvHP8) and 9.15 (PvPRR10). The majority of PvTCS genes are unstable. Phylogenetic analysis of TCS genes in A. thaliana, G. max, and bean found that PvTCS genes had close phylogenetic relationships with the genes of other plants. Segmental and tandem duplicate gene pairs were detected among the TCS genes and TCS genes have been subjected to purifying selection pressure in the evolutionary process. Furthermore, the TCS gene family, which has an important role in abiotic stress and hormonal responses in plants, was characterized for the first time in beans, and its expression of TCS genes in bean leaves under salt and drought stress was established using RNAseq and qRT-PCR analyses. The findings of this study will aid future functional and genomic studies by providing essential information about the members of the TCS gene family in beans.

Phylogenetic relationship among taxa in the genus Adonis L. collected from Türkiye based on nrDNA internal transcribed spacer (ITS) markers.

BACKGROUND: Genus Adonis L. contain approximately 40 annual and perennial species, which are widely distributed in the temperate zones of Asia and Europe, and less frequently in southwestern Asia, northern Africa and the Mediterranean region. The aim of the study was to evaluate the phylogenetic relationship among Adonis taxa collected from Türkiye based on nrDNA Internal transcribed spacer (ITS) markers. METHODS: Samples of 64 individual genotypes from 21 populations of 10 Adonis taxa were collected from different regions of the country during vegetation period between 2014 and 2018. ITS1, ITS4, P16 and P25 primers within ITS technique was used to genotype the plant materials. Then, genotypic data was used to estimate magnitude and organization of infraspecific variation in different populations of Adonis. RESULTS: About 600 bp DNA sequences were obtained from each 64 Adonis genotypes belonging to 21 different populations. The dendrogram obtained from Adonis taxa and out-group sequences had two large main groups. While the out-group species were placed in the first large main group, the sect. Consiligo (perennial) and sect. Adonis (annuals) were placed in different sub-groups of the second large main group. Genetic similarity among Adonis taxa varied between A. microcarpa and A. dentata (98.46%). Principal component analysis indicated that two important components in Adonis taxa genotypes. The expected heterozygosity ranged from 0.0252 (sub-population A) to 0.3460 (sub-population C), with an average of 0.1154. In addition, population differentiation measurements (Fst) ranged from 0.0025 (sub-population C) to 0.9016 (sub-population A) with a relatively high average 0.6601. CONCLUSIONS: Present analyses revealed that phylogenetic classification (grouping) of Adonis taxa largely depended on morphological structure and present ITS primers were quite efficient in putting forth the genetic diversity of such species. The results of this study suggested that ITS markers could be used in the identification of genetic diversity among the Adonis taxa. The results obtained from molecular data can be used to explore the genetic variation pattern, population structure, and the evolutionary history of genus Adonis in the future.

The type and scope of physiotherapy is under-utilised in Australian residential aged care facilities: a national, cross-sectional survey of physiotherapists.

BACKGROUND: With an increasingly ageing population in Australia, more older adults who are frail are living in residential aged care facilities (RACFs). The aim of this study was to detail the type, scope, and funding of physiotherapy utilised in Australian RACFs. METHODS: Registered physiotherapists (n = 219, 72% female, mean age (SD) = 38.6 (12.9) years) working in Australian RACFs participated in a nationwide, cross-sectional online survey. The survey was developed iteratively through a review of the literature and clinical guidelines, consensus of final survey items by an expert panel of five senior physiotherapists and aged care managers. Survey questions related to the characteristics of the physiotherapists (e.g., age, gender, employment status), characteristics of the RACFs (e.g., state, remoteness, sector), the type and scope of physiotherapy provided by respondents, and the availability of equipment and certain spaces (e.g., gyms) in the RACFs that respondents worked in. Survey responses were analysed and presented descriptively. Correlation using Spearman's rho (ρ) and the associated 95% confidence intervals (CI) were used to determine whether the availability of equipment or space at the RACF was associated with the time dedicated to performing non-Aged Care Funding Instrument (ACFI) tasks. RESULTS: Common reasons for physiotherapy referral were chronic pain management as per the ACFI framework (89.7%), falls (69.2%), and reduced mobility (35.9%). Rehabilitation or short-term restorative care was provided in only 22.2% of the facilities. The ACFI funded 91.4% of all participants, which limited physiotherapists to low-value chronic pain management including massage and electrical stimulation. Respondents spent 64.5% of their time on ACFI tasks, which equated to 19 h per week. More time was spent on non-ACFI tasks particularly when resistance bands (ρ = 0.28, 95%CI 0.14-0.41) and a dedicated therapy space or gym (ρ = 0.19, 95%CI 0.04-0.33) were available. CONCLUSIONS: The expertise of physiotherapists is currently being under-utilised in Australian RACFs, which may be related to the availability of public funding, equipment, and space for therapy. Therefore, public health policy should address the urgent need for high-value, evidence-based physiotherapy that supports the reablement and independence of older adults living in RACFs.

Neonates as intrinsically worthy recipients of pain management in neonatal intensive care.

One barrier to optimal pain management in the neonatal intensive care unit (NICU) is how the healthcare community perceives, and therefore manages, neonatal pain. In this paper, we emphasise that healthcare professionals not only have a professional obligation to care for neonates in the NICU, but that these patients are intrinsically worthy of care. We discuss the conditions that make neonates worthy recipients of pain management by highlighting how neonates are (1) vulnerable to pain and harm, and (2) completely dependent on others for pain management. We argue for a relational account of ethical decision-making in the NICU by demonstrating how an increase in vulnerability and dependence may be experienced by the healthcare community and the neonate's family. Finally, an ethical framework for decisions around neonatal pain management is proposed, focussing on surrogate decision-making and the importance of compassionate action through both a reflective and an affective empathy. As empathy can be highly motivating against pain, we propose that, in addition to educational programs that raise awareness and knowledge of neonatal pain and pain management, healthcare professionals must cultivate empathy in a collective manner, where all members of the NICU team, including parents, are compassionate decision-makers.

Genome of wild olive and the evolution of oil biosynthesis.

Here we present the genome sequence and annotation of the wild olive tree (Olea europaea var. sylvestris), called oleaster, which is considered an ancestor of cultivated olive trees. More than 50,000 protein-coding genes were predicted, a majority of which could be anchored to 23 pseudochromosomes obtained through a newly constructed genetic map. The oleaster genome contains signatures of two Oleaceae lineage-specific paleopolyploidy events, dated at ∼28 and ∼59 Mya. These events contributed to the expansion and neofunctionalization of genes and gene families that play important roles in oil biosynthesis. The functional divergence of oil biosynthesis pathway genes, such as FAD2, SACPD, EAR, and ACPTE, following duplication, has been responsible for the differential accumulation of oleic and linoleic acids produced in olive compared with sesame, a closely related oil crop. Duplicated oleaster FAD2 genes are regulated by an siRNA derived from a transposable element-rich region, leading to suppressed levels of FAD2 gene expression. Additionally, neofunctionalization of members of the SACPD gene family has led to increased expression of SACPD2, 3, 5, and 7, consequently resulting in an increased desaturation of steric acid. Taken together, decreased FAD2 expression and increased SACPD expression likely explain the accumulation of exceptionally high levels of oleic acid in olive. The oleaster genome thus provides important insights into the evolution of oil biosynthesis and will be a valuable resource for oil crop genomics.

Genome-wide identification of CAMTA gene family members in Phaseolus vulgaris L. and their expression profiling during salt stress.

The calmodulin-binding transcriptional activator (CAMTA) family was first observed in tobacco (NtER1) during a screening for the CaM-binding proteins, which are known to be one of the fast response stress proteins. Due to the increased importance of plant transcription factors in recent years; genome-wide identification of CAMTA genes has been performed in several plant species, except for Phaseolus vulgaris. Therefore, our aim was to identify and characterize CAMTA genes in P. vulgaris via in silico genome-wide analysis approach. Our results showed a total of eight CAMTA genes that were identified and observed on five out of 11 chromosomes of P. vulgaris. Four gene couples were found to be segmentally-duplicated and these segmental duplication events were shown to occur from 29.97 to 92.06 MYA. The phylogenetic tree of CAMTA homologs from P. vulgaris, A. thaliana, and G. max. revealed three groups based on their homology and the intron numbers of Pvul-CAMTA genes, ranged from 11 to 12. According to the syteny analysis; CAMTA genes of P. vulgaris and G. max revealed higher similarity, because they have highly similar genomes compared to A. thaliana. All Pvul-CAMTA genes were targeted by miRNAs, which play a role in response mechanism of salt stress. To detect expression levels in different plant tissues, mRNA analysis of Pvul-CAMTA genes were performed using publicly available expression data in Phytozome v12.1. In addition, responses of Pvul-CAMTA genes to salt stress, were also examined via both RNAseq and qRT-PCR analysis. To identify and to obtain insight into biological functions of CAMTA genes in the genome of P. vulgaris, several analyses were conducted using many online and offline bioinformatic tools, genome databases and qRT-PCR analyses. Due to this study being the first in the identification of CAMTA genes in P. vulgaris, this study could be considered as an useful source for future CAMTA genes studies in either P. vulgaris or comparative different plant species.

Systematic review and meta-analysis suggest that varying prevalence of non-acute pain in critically ill infants may be due to different definitions.

AIM: Our aim was to quantify the prevalence of non-acute pain in critically ill infants and to identify how non-acute pain was described, defined and assessed. METHODS: This systematic review and meta-analysis used multiple electronic databases to search for papers published in any language to March 2018: 2029 papers were identified, and 68 full texts were screened. Studies reporting the prevalence of non-acute pain in infants younger than 2 years and admitted to critical care units were included. The extracted data included the use of non-acute pain descriptions, definitions and pain assessment tools. RESULTS: We included 11 studies published between 2002 and 2018 that comprised 1204 infants from Europe, the USA, Canada and India. They were prospective observational (n = 7) and retrospective observational (n = 1) studies and randomised controlled trials (n = 3). The prevalence of non-acute pain was 0%-76% (median 11%). Various pain assessment tools were used, and only two could be pooled. This gave a pooled prevalence of 3.7%-39.8%. A number of different descriptors were used for non-acute pain, and all of these were poorly defined. CONCLUSION: The prevalence of non-acute pain in infants admitted to critical care units varied considerably. This could have been because all the studies used different definitions of non-acute pain.

Genome-wide identification of salinity responsive HSP70s in common bean.

The present study is aimed to identify and characterize HSP70 (PvHSP70) genes in two different common bean cultivars under salt stress. For this purpose various in silico methods such as RNAseq data and qRT-PCR analysis were used. A total of 24 candidate PvHSP70 gene were identified. Except for chromosome 4 and 7, these candidate PvHSP70 genes were distributed on the remaining chromosomes. While the lowest number of PvHSP70 genes was determined on chromosomes 1, 3, 5, 7, 9, 10 and 11 (one HSP70 gene), the highest number of PvHSP70s was on chromosomes 6 and 8 (seven HSP70 genes each). Three genes; PvHSP70-5, -9, and -10 were found to have no-introns. In addition, four tandemly and six segmentally duplicated gene couples were detected. A total of 13 PvHSP70 genes were targeted by miRNAs of 44 plant species and the most targeted genes were PvHSP70-5 and -23. The expression profile of PvHSP70 genes based on publicly available RNA-seq data was identified and salt treated leaf tissue was found to have more gene expression levels compared to the root. qRT-PCR analysis showed that the transcript concentrations of upregulated PvHSP70 genes in leaves of Zulbiye (sensitive) were mostly higher than those of Yakutiye (resistant). The present study revealed that PvHSP70 genes might play an important role in salt stress response for common bean cultivars and variability between cultivars also suggests that these genes could be used as functional markers for salt tolerance in common bean.

Molecular and ecological investigations on the wild populations of Glycyrrhiza L. taxa distributed in the East Mediterranean Area of Turkey.

This paper covers studies on the molecular and ecological aspects of G. glabra var. glandulifera, G. flavescens ssp. flavescens and G. echinata collected from Hatay (Turkey); with the aim to better understand their genetic variation and ecological requirements for possible conservation programs. The material including total genomic DNA was extracted by the CTAB, and for PCR reaction, a total of 14 SSR primers developed for Medicago truncatula were used. PCR amplifications were performed in a Multigen® Thermal Cycler. Soil samples were analysed for their texture, pH, total soluble salts, calcium carbonate, total N content, total phosphorus and organic matter content. In order to see the association between genetic, ecological and geographical data, a similarity matrix was generated. Genetic similarity distances between genotypes were correlated with those of Eucledian distances obtained from ecological and geographical data. Analysis of molecular variance (AMOVA) was performed using GenAlEx 6.5 software to determine variation among and within genetic variations. The genetic analysis showed that the highest expected heterozygosity values were obtained from G. glabra while the lowest were obtained from G. echinata. In general heterozygosity values were low, especially for G. echinata. Therefore, variation appears to be lower within each species than among three species. The physical and chemical analysis of soil and plant samples indicates that mineral accumulation in plants is substantially affected by the soil characteristics. There is a need for identification of better strategies for the improvement of varieties, especially for small farmers managing marginal soils. More studies should be conducted in order to safeguard these taxa, especially G. glabra var. glandulifera which is collected intensively due to its economic value, the same is true for endemic taxon G. flavescens ssp. flavescens.

Genome-wide fungal stress responsive miRNA expression in wheat.

MicroRNAs (miRNAs) are small non-coding class of RNAs. They were identified in many plants with their diverse regulatory roles in several cellular and metabolic processes. A number of miRNAs were involved in biotic and abiotic stress responses. Here, fungal stress responsive wheat miRNAs were analyzed by using miRNA-microarray strategy. Two different fungi (Fusarium culmorum and Bipolaris sorokiniana) were inoculated on resistant and sensitive wheat cultivars. A total of 87 differentially regulated miRNAs were detected in the 8 × 15 K array including all of the available plant miRNAs. Using bioinformatics tools, the target transcripts of responsive miRNAs were predicted, and related biological processes and mechanisms were assessed. A number of the miRNAs such as miR2592s, miR869.1, miR169b were highly differentially regulated showing more than 200-fold change upon fungal-inoculation. Some of the miRNAs were identified as fungal-inoculation responsive for the first time. The analyses showed that some of the differentially regulated miRNAs targeted resistance-related genes such as LRR, glucuronosyl transferase, peroxidase and Pto kinase. The comparison of the two miRNA-microarray analyses indicated that fungal-responsive wheat miRNAs were differentially regulated in pathogen- and cultivar-specific manners.

The Targeted Motor Control Screening Tool Is Valid for 4-Year-Old Children.

OBJECTIVE: The objective was to determine the validity of the Targeted Motor Control (TMC) screening tool with the Neurosensory Motor Developmental Assessment (NSMDA) in 4-year-old children. METHODS: In this single cohort observational study, children (3 years 9 months to 4 years 5 months) completed the TMC and the NSMDA in a randomized order 5 to 14 days apart. RESULTS: Seventy-six children (mean age = 4 years 2 months; standard deviation = 2.5 months; n = 35 male) completed both assessments. Forty-two children performed within the normal range on the NSMDA. There were significant and positive moderate correlations between the item totals overall and for each area on the NSMDA and the TMC (r = 0.40-0.61), and between the NSMDA functional grade for each area and the corresponding TMC areas (r = 0.47-0.67). However, the correlation between the NSMDA sensorimotor functional grade and the TMC sensory score was significant but low and positive (r = 0.35). The optimal cut-off score for detecting children at risk of atypical development on the TMC was a score of <9 (n = 42) (sensitivity = 82.4%; specificity = 66.7%), with a positive likelihood ratio of 2.47 (95% confidence interval [CI] = 1.57-3.89) and a negative likelihood ratio of 0.26 (95% CI = 0.12-0.56). CONCLUSION: The TMC is a valid screening tool to identify 4-year-old children at risk of motor delay. IMPACT: Early identification of developmental concerns using a validated screening tool is recommended. The TMC is a valid performance-based screening tool that can be used to identify children at risk of atypical motor development who would benefit from further developmental assessment so that, if indicated, timely intervention can be implemented.

An online pain management program for people with hypermobile Ehlers-Danlos Syndrome or hypermobility spectrum disorder: a three-staged development process.

PURPOSE: Hypermobile Ehlers-Danlos Syndrome (hEDS) and hypermobility spectrum disorder (HSD) are painful, chronic and multi-systemic conditions. No online pain management programs for hEDS/HSD currently exist. We aimed to develop one by exploring what people with hEDS/HSD want in such programs. MATERIALS AND METHODS: A Delphi was conducted via online surveys of stakeholders: participants with hEDS/HSD and healthcare professionals (HCP). In survey 1, participants were asked if a hEDS/HSD-specific online pain management program was important, listing up to 20 topics important to know about pain. In survey 2, participants rated the importance of those topics. Consensus was set as ≥75% rating of at least "important". Using topics that reached consensus, the online program was developed. Usability testing was performed using the Systems Usability Scale (SUS). RESULTS: 396 hEDS/HSD and 29 HCP completed survey 1; 151 hEDS/HSD and 12 HCP completed survey 2. 81% of hEDS/HSD and 69% of HCP rated a hEDS/HSD-specific program as at least "important". Thirty-five topics reached consensus to guide content for the HOPE program (Hypermobile Online Pain managemEnt). SUS score was 82.5, corresponding to "high acceptability". CONCLUSIONS: A hEDS/HSD-specific online pain management program is important to stakeholders. Utilising a Delphi approach to incorporate stakeholder input, an evidence-informed and user appropriate program was developed.

Pain is one of the most common and impactful symptom affecting those with Hypermobile Ehlers-Danlos Syndrome (hEDS) and hypermobility spectrum disorder (HSD).Online pain management programs are effective in other chronic conditions such as Fibromyalgia and Rheumatoid Arthritis, but there are no programs specific for hEDS/HSD.People with hEDS or HSD and healthcare professionals with experience in these conditions feel that an online pain management program specific to their condition is important; consensus revealed thirty-five key topics important to these stakeholders.The first hEDS/HSD-specific online pain management program, called HOPE, was developed with stakeholder input and usability tested, ready for clinical trial testing.

N-acetyl-cysteine mitigates arsenic stress in lettuce: Molecular, biochemical, and physiological perspective.

Agricultural land contaminated with heavy metals such as non-biodegradable arsenic (As) has become a serious global problem as it adversely affects agricultural productivity, food security and human health. Therefore, in this study, we investigated how the administration of N-acetyl-cysteine (NAC), regulates the physio-biochemical and gene expression level to reduce As toxicity in lettuce. According to our results, different NAC levels (125, 250 and 500 µM) significantly alleviated the growth inhibition and toxicity induced by As stress (20 mg/L). Shoot fresh weight, root fresh weight, shoot dry weight and root dry weight (33.05%, 55.34%, 17.97% and 46.20%, respectively) were decreased in plants grown in As-contaminated soils compared to lettuce plants grown in soils without the addition of As. However, NAC applications together with As stress increased these growth parameters. While the highest increase in shoot fresh and dry weight (58.31% and 37.85%, respectively) was observed in 250 µM NAC application, the highest increase in root fresh and dry weight (75.97% and 63.07%, respectively) was observed in 125 µM NAC application in plants grown in As-polluted soils. NAC application decreased the amount of ROS, MDA and H2O2 that increased with As stress, and decreased oxidative damage by regulating hormone levels, antioxidant and enzymes involved in nitrogen metabolism. According to gene expression profiles, LsHIPP28 and LsABC3 genes have shown important roles in reducing As toxicity in leaves. This study will provide insight for future studies on how NAC applications develop resistance to As stress in lettuce.

How Schroth Therapists Vary the Implementation of Schroth Worldwide for Adolescents with Idiopathic Scoliosis: A Mixed Methods Study.

(1) Background: Schroth is a type of physiotherapeutic scoliosis specific exercise (PSSE) prescribed to adolescents with idiopathic scoliosis (AIS). Studies have investigated the effectiveness of Schroth but are yet to elucidate how Schroth is applied clinically and the factors that influence their prescription. (2) Methods: A mixed methods design was used comprising an anonymous survey and semi-structured interviews of Schroth therapists who treated AIS and who were publicly listed on the Barcelona Scoliosis Physical Therapy School or the International Schroth 3-dimensional Scoliosis Therapy School websites. The survey included 64 questions covering demographics, session and treatment characteristics, and whether therapists included other treatment modalities in their clinical practice. A convenience sample of survey participants were invited to participate in a semi-structured interview to further explore the factors that influenced their prescription of Schroth for AIS. Results from the survey were analyzed descriptively (n, %), whereas inductive thematic analysis was used for the interviews. (3) Results: of the 173 survey respondents (18% response rate), most were from Europe and North America (64.0%), female (78.6%), physiotherapists (96.0%), and worked in private settings (72.3%). Fifty-two per cent of participants used other types of PSSE as an adjunct to Schroth, the Scientific Exercise Approach to Scoliosis (SEAS) being the most frequently used (37.9%). Non-PSSE methods were used 'at some point' as an adjunct by 98.8% of participants, including massage and other soft tissue techniques (80.9%), Pilates (46.6%), and Yoga (31.5%). The Schroth techniques used by all survey respondents included breathing and pelvic corrections. Seven participants were interviewed, but data saturation was achieved after only four interviews. Thematic analysis revealed four, inter-related broad themes describing the factors that influenced Schroth prescription for AIS: (1) the adolescent as a whole, including physical, emotional and mental characteristics, and patient goals, (2) family, including parent relationship with the adolescent and the motivation of parents in regard to Schroth, (3) the systems within which the treatment was being offered, such as vicinity to the clinic and the presence of financial insurance support, and (4) therapist characteristics, such as their training and experience. (4) Conclusions: Schroth therapists worldwide use a variety of adjunctive methods to treat AIS. Therapists prescribing Schroth exercises to AIS consider the complex interplay of intra-, inter- and extra-personal factors in clinical practice. These considerations move beyond the three components of evidence-based practice of research, patient preferences, and clinical expertise, towards a systems-based reflection on exercise prescription.

Precision Segmental Preservation Rhinoplasty: Avoiding Widening, Defining New Dorsal Esthetic Lines in Dorsal Preservation Rhinoplasty.

Experiencing great worldwide scientific excitement, the number of nose preservation surgeries has increased rapidly, promoting a considerable percentage of drawbacks and complications, causing many surgeons to recoil and return to classic resective techniques. In this study, we develop concepts that allow us to operate noses with preservation rhinoplasty that were previously considered to be among the absolute contraindications. Redefining new dorsal aesthetic lines, controlling the nasal lateral wall and the naso-facial groove surfaces, avoiding mid-vault widening and being precise in the design of bony and cartilaginous nasal profile, avoiding any type of irregularity, are strategies that will be presented.

Identification of Novel QTLs Associated with Frost Tolerance in Winter Wheat (Triticum aestivum L.).

Low temperature (cold) and freezing stress is a major problem during winter wheat growth. Low temperature tolerance (LT) is an important agronomic trait in winter wheat and determines the plants' ability to cope with below-freezing temperatures; thus, the development of cold-tolerant cultivars has become a major goal of breeding in various regions of the world. In this study, we sought to identify quantitative trait loci (QTL) using molecular markers related to freezing tolerance in winter. Thirty-four polymorphic markers among 425 SSR markers were obtained for the population, including 180 inbred lines of F12 generation wheat, derived from crosses (Norstar × Zagros) after testing with parents. LT50 is used as an effective selection criterion for identifying frost-tolerance genotypes. The progeny of individual F12 plants were used to evaluate LT50. Several QTLs related to wheat yield, including heading time period, 1000-seed weight, and number of surviving plants after overwintering, were identified. Single-marker analysis illustrated that four SSR markers with a total of 25% phenotypic variance determination were linked to LT50. Related QTLs were located on chromosomes 4A, 2B, and 3B. Common QTLs identified in two cropping seasons based on agronomical traits were two QTLs for heading time period, one QTL for 1000-seed weight, and six QTLs for number of surviving plants after overwintering. The four markers identified linked to LT50 significantly affected both LT50 and yield-related traits simultaneously. This is the first report to identify a major-effect QTL related to frost tolerance on chromosome 4A by the marker XGWM160. It is possible that some QTLs are closely related to pleiotropic effects that control two or more traits simultaneously, and this feature can be used as a factor to select frost-resistant lines in plant breeding programs.
