Aim: To analyze the association between clavicular tunnel positioning and postoperative reduction loss in patients with acute acromioclavicular (AC) joint dislocation treated with anatomic coracoclavicular (CC) fixation using double clavicular tunnels.
Methods: A retrospective review of patients with AC joint dislocation, treated with anatomic CC fixation using double clavicular tunnels, was conducted. Patients with pre-operative, immediate post-operative, and final follow-up Zanca-view X-rays were included.
Introduction: in patients with anterior glenohumeral (GH) instability together with an off-track or engaging Hill-Sachs (HS) defect, Bankart-remplissage (B-R) surgery reduces the recurrence rate when compared to Bankart (B) surgery alone. There is controversy regarding whether the recurrence rate also decreases in patients with on-track or non-engaging Hill-Sachs defects.
Objective: to compare the recurrence rate and clinical evolution of patients with anterior glenohumeral instability with 'on-track' Hill-Sachs defect treated with either B or B-R surgery.
The study aimed to determine the enhanced effects of essential oils (EOs) and plant-derived molecules (PDMs) as penetration enhancers (PEs) for transdermal drug delivery (TDD) of caffeine. A 1% / solution of eight EOs and seven PDMs was included in the 1% caffeine carbopol hydrogel. Franz diffusion cell experiments were performed using mice with full-thickness skin.

The research included yield trials in farmers' fields during 4 production seasons (2012-2016), adaptation and agronomic efficiency trials in two production seasons (2016-2018). In addition, the reaction to Yellow Rust and distinctness, uniformity and stability characteristics of the new wheat variety and commercial controls were evaluated.

In this work, a novel biocomposite coating was synthesised by mixing PCL with layers of calcium phosphate (hydroxyapatite, brushite and monetite) from a biomineral called otolith extracted from Teleost fish (Plagioscion Squamosissimus) and multiwalled carbon nanotubes in different concentrations (0.5, 1.

The aim of this work was to study cell internalization, reactive oxygen species (ROS) production, and toxicity/genotoxicity and transdermal delivery of UDL-ClAlPc, and to determine whether PDT was able to induce anti-leishmanial activity in Leishmania (Viannia) braziliensis experimental models. Prepared liposomes had an average size of 118.

During early stages of brain formation, ethanol affects the evagination of the optic vesicles, resulting in synophthalmia or cyclopia, phenotypes where the optic vesicles partially or totally fuse. The mechanisms by which ethanol affects the morphogenesis of the optic vesicles are however largely unknown.

Linkage and association studies have suggested that one or more clefting loci may be located on chromosome 4q. The goal of this study was to evaluate the possible linkage and association due to linkage disequilibrium between five microsatellite markers located on 4q28 to 4q33 and NSCLP, using the case-parent trio design.

Linkage and association studies have suggested that a clefting locus could be located on chromosome 4p. Sixty Chilean families were recruited for this study; from these, we used unrelated trios to evaluate the possible linkage disequilibrium between MSX1 and NSCLP.
View Article and Find Full Text PDFObjectives: The objective of this case-control study was to evaluate the possible association between nonsyndromic cleft lip/palate (NSCLP) and 10 genetic markers in four chromosomal regions in the admixed Spanish-Amerindian Chilean population.
Setting: Study participants included 56 patients with NSCLP identified and interviewed for positive family history during the course of clinical examinations at different rehabilitation centers in the cities of Santiago and Talca, Chile. A control group of 59 normal individuals without known familial antecedents of clefting was obtained from blood bank donors of the University Hospital, University of Chile.
Background: Genetic studies indicate that nonsyndromic cleft lip/palate (NSCLP) has the characteristics of a complex genetic trait. Reports from different authors have suggested several candidate genes mapping in different chromosome regions. Association studies have suggested that a clefting locus is located on chromosome 6p.
View Article and Find Full Text PDFBackground: In the search of the major genes responsible for the genetic etiology of Nonsyndromic Cleft Lip and Palate (NSCLP), an association study between this malformation and four molecular markers, F13A1 and EDN1 (6p), D17S579 (17q) and BCL3 (19q), was done.
Aim: To determine, in a Chilean population, the presence of NSCLP susceptibility regions, as proposed for Caucasian populations in the 6p, 17q and 19q chromosomal regions.
Material And Methods: A sample of unrelated NSCLP patients, that belonged to Simplex (Sx) and Multiplex (Mx) families, was analyzed.
Prior studies have implicated an involvement of the Msx1 homeobox gene in cleft palate in mice and its homolog in humans (called MSX1 in the HOX7 gene, located on chromosome 4). In this study we present evidence of a sex-dependent association between MSX1 and non-syndromic cleft lip/palate (NSCLP) in the Chilean population. The sample included 73 NSCLP cases, 37 from multiplex families (Mx), 36 from simplex families (Sx), and 87 controls.

Aim: To test the hypothesis on the possible presence of a clefting locus on chromosome 4q.
Background: Nonsyndromic cleft lip with or without cleft palate (NSCLP) is a common craniofacial developmental defect. Association studies have suggested that a clefting locus is located on chromosome 6p at or near two possible loci, Factor 13A (FI3A) in the region 6p 25-24 and HLA at 6p 21.3.
View Article and Find Full Text PDFBackground: Recent studies in mice have demonstrated that the Msx-1 homebox gene is implicated in cleft palate. Thus, it has been suggested that its human homologue, MSX1 (HOX-7), located in chromosome 4 could be involved in the etiology of non syndromic cleft lip palate.
Aim: To study the linkage between non syndromic cleft palate and variations of MSX1 gene.
Two RFLPs at the TGFA locus were studied in 39 unrelated Chilean (Caucasoid-Mongoloid) patients with non-syndromic cleft lip/palate [CL(P)] and 51 control individuals. A highly significant association between BamHI A2 allele and CL(P) was detected (chi 2 = 6.00; P = 0.

Three major schizodeme groups were discriminated. There was a correlation between the Chilean schizodeme groups (S1, S2, or S3) and the zymodemes known to occur in Chile (Z1, Brazilian Z2 and Bolivian Z2, respectively), although heterogeneity was seen within the schizodeme groups S2 and S3.
