Assessment of Scapular Morphometry

WOS: 000454335600026The current study was undertaken to assess the incidence of different types of suprascapular notch, acromion dimensions and the lower and upper scapular angles. The suprascapular notch and variations of the acromion are clinically important in suprascapular nerve compression and subacromial impingement. Measurements were taken from 73 Anatolian dry scapulae of unknown age or sex. The suprascapuar notch was classified according to that of Rengachary et al. (1979). Its width and depth, the distance between supraglenoid tubercle and the deepest point of notch, as well as the upper and lower scapular angles were also determine measured. The type of acromion was assessed according to shape (type I (cobra), type II (square), type III (intermediate)) and tilt (type I (flat), type II (curve). Acromion length and the distance between acromion and coracoid process were also measured. The frequency of different types of suprascapular notch were type I (28.8 %), type II (23.3 %), type III (13.7 %), type IV (20.5 %), type V (2.7 %), type VI (5.5 %)and absence (5.5 %). Acromion type were type I (45.5 %), type II (7.5 %) and type III (47.0 %), acromion tilt type I (15.2 %), and type II (84.8 %). An understanding of the association between the anatomical structures of the scapula and morphometric measurements is clinically important

Morphometric Measurement and Types of Articular Facets on the Talus and Calcaneus in an Anatolian Population

Anatomical variations in terms of ligamentous attachments, articulations and bony morphology are common in the subtalar region. The shape of the articular facets of the talus and calcaneus and their relationship to each other are important for joint function and surgical procedures. In this study an assessment of the morphology of the articular facets of the talus and calcaneus, in an Anatolian population, was undertaken. 49 tali and 57 calcanei from Anatolian adults of unknown gender were examined. The types of articular facets on the talus and calcaneus were determined using the following classification: Type A1, the distance between the anterior and middle facets was less than 2 mm; Type A2, the distance between the anterior and middle facets was 2-5 mm; Type A3, the distance between the anterior and middle facets was more than 5 mm; Type A4, there was only one articular facet; Type B1, the separation between the anterior and middle facets was not complete; Type B2, separation of the anterior and middle facets was present; Type C, no separation between the anterior, middle and posterior facets was present, i.e. there was one articular facet. In addition, the anteroposterior length and width of the talus and calcaneus, together with the width, length and depth of sulcus tali and sulcus calcanei were determined. Left and right tali, respectively, displayed the folowing types of articular facet: A1, 0 %, 0 %; A2, 0 %, 3,4 %; A3, 0 %, 0 %; A4, 0 %, 0 %; B1, 60 %, 51,8 %; and B2, 40 %, 44.8 %. Articular facets on left and right calcanei, respectively, were: A1, 10 %, 7.4 %; A2, 10 %, 14.8 %; A3, 16.7 %, 11.1 %; A4, 3.3 %, 3.7 %; B1, 30 %, 22.2 %; B2, 30 %, 40.8 %. The length and width of left and right tali were 50.5 +/- 3.81 mm and 39.5 +/- 2.97 mm, and 53.1 +/- 4.38 mm and 39.3 +/- 3.66 mm, respectively. The width, length and depth of left and right sulcus tali were: 5.2 +/- 1.09 mm, 21.7 +/- 2.73 mm and 5.7 +/- 0.84 mm, and 6.1 +/- 2.05 mm, 21.1 +/- 3.66 mm and 5.7 +/- 1.52 mm, respectively. For left and right calcanei length and width were; 76.1 +/- 5.44 mm 44.0 +/- 3.97 mm, and 75.7 +/- 6.76 mm and 45.9 +/- 4.21 mm, respectively. The width, length and depth of left and right sulcus calcanei were: 6.4 +/- 1.19 mm, 31.9 +/- 2.76 mm and 4.0 +/- 0.81 mm, and 5.5 +/- 1.00 mm, 32.4 +/- 3.23 mm and 4.4 +/- 1.05 mm, respectively. The articular facets on both the talus and calcaneus in the Anatolian population studied was predominantly type B. This observations is similar to previous reports conducted in America, India and Africa, but differ from those undertaken in Europe. A knowledge of variations of the articular facets of the talus and calcaneus provides a valuable road map for orthopaedic surgeons, as well as others involved in foot rehabilitation

Protein-protein interactions among the structural proteins of chilo iridescent virus

Chilo iridescent virus (CIV), officially named invertebrate iridescent virus 6 (IIV6), is a nucleocytoplasmic virus with a ~212-kb linear dsDNA genome that encodes 215 putative open reading frames (ORFs). Proteomic analysis has revealed that the CIV virion consists of 54 virally encoded proteins. In this study, we identified the interactions between the structural proteins using the yeast two-hybrid system. We cloned 47 structural genes into both bait and prey vectors, and then analysed the interactions in Saccharomyces cerevisiae strain AH109. A total of 159 protein-protein interactions were detected between the CIV structural proteins. Only ORF 179R showed a self-association. Four structural proteins that have homologues in iridoviruses (118L, 142R, 274L and 295L) showed indirect interactions with each other. Seven proteins (138R, 142R, 361L, 378R, 395R, 415R and 453R) interacted with the major capsid protein 274L. The putative membrane protein 118L, a homologue of the frog virus 3/Ranagrylio virus 53R protein, showed direct interactions with nine other proteins (117L, 229L, 307L, 355R, 366R, 374R, 378R, 415R and 422L). The interaction between 118L and 415R was confirmed by a GST pull-down assay. These data indicate that 415R is a potential matrix protein connecting the envelope protein 118L with the major capsid protein 274L.</p

Surface landmarks for suboccipital craniotomy

Surface anatomic landmarks of the skull are important to ensure proper surgical planning and approaches. Localization of internal cranial anatomic features based on such landmarks is essential for identifying and avoiding important anatomic structures, minimizing complications and decreasing surgical morbidity. Twenty-five adult dry Anatolian skulls of unknown age and sex from the collection of the Department of Anatomy, Faculty of Medicine, Cukurova University were examined to determine the relationships between specific landmarks. Mean distances and associated SDs for the right and left sides for each of the following were: asterion to the root of the zygoma 53.03±3.53 and 50.46±4.97 mm, asterion to the tip of the mastoid process 49.71±3.92 and 49.17±4.16 mm, asterion to the digastric point 29.32±7.09 and 28.78±4.89 mm, digastric point to the occipitomastoid suture 6.89±4.21 and 6.95±4.02 mm, digastric point to the jugular point 25.14±5.15 and 25.29±5.38 mm, jugular point to the stylomastoid foramen 8.08±1.95 and 6.81±1.47 mm, stylomastoid foramen to the jugular foramen 6.11±2.33 and 7.08±1.90 mm, and projection of the digastric point to the border of the sigmoid sinus 3.20±1.62 and 3.09±1.92 mm. In addition, the presence of a septum associated with the jugular foramen was noted as a no septum (62.5% and 70.8%), incomplete (29.2% and 16.7%), and complete (8.3% and 12.5%) on the right and left sides, respectively. These distances will aid neurosurgeons in safely placing burr holes for suboccipital craniotomy. Copyright © 2013 by Lippincott Williams & Wilkins

Surgical importance of the morphometry of the anterior clinoid process, optic strut, caroticoclinoid foramen, and interclinoid osseous bridge

This study was undertaken to determine the morphometry of the anterior clinoid process (ACP), optic strut (OS), caroticoclinoid foramen, and interclinoid osseous bridge in skulls of Turkish adults. Measurements were taken from 34 dry skulls of unknown age and sex. The overall means, and associated standard deviations, of the distances measured are: basal width of the ACP at the medial margin of the optic canal (OC) 12.4±2.1 mm; from the anterior clinoid tip (ACT) to the base of the ACP 11.5±1.9 mm; from the ACT to the posterior margin of the OS 6.9±1.6 mm; thickness of the ACP 4.3±1.2 mm; from the ACT to the junction of the medial edge of the ACP and the posterolateral edge of the OC roof 8.9±1.6 mm; from the ACT to the center point of the posterior edge of the OC roof 11.4±1.7 mm; from the ACT to the lateral end of the superior orbital fissure 23.7±3.9 mm; from the ACT to the anterior edge of the OS base 8.6±1.7 mm; from the ACT to the posterior edge of the OS base 6.5±1.5 mm; from the ACT to the posterior clinoid process 10.6±2.4 mm; between the ACTs 25.8±2.7 mm. In addition, the presence of a caroticoclinoid process and interclinoid bridge was identified and the types were classified. Knowledge of the morphometry of the parasellar and suprasellar regions is extremely important for neurosurgeons. Copyright © 2011 by Lippincott Williams & Wilkins

Kveik Brewing Yeasts Demonstrate Wide Flexibility in Beer Fermentation Temperature Tolerance and Exhibit Enhanced Trehalose Accumulation

Traditional Norwegian Farmhouse ale yeasts, also known as kveik, have captured the attention of the brewing community in recent years. Kveik were recently reported as fast fermenting thermo- and ethanol tolerant yeasts with the capacity to produce a variety of interesting flavor metabolites. They are a genetically distinct group of domesticated beer yeasts of admixed origin with one parent from the “Beer 1” clade and the other unknown. While kveik are known to ferment wort efficiently at warmer temperatures, their range of fermentation temperatures and corresponding fermentation efficiencies, remain uncharacterized. In addition, the characteristics responsible for their increased thermotolerance remain largely unknown. Here we demonstrate variation in kveik strains at a wide range of fermentation temperatures and show not all kveik strains are equal in fermentation performance and stress tolerance. Furthermore, we uncovered an increased capacity of kveik strains to accumulate intracellular trehalose, which likely contributes to their increased thermo- and ethanol tolerances. Taken together our results present a clearer picture of the future opportunities presented by Norwegian kveik yeasts and offer further insight into their applications in brewing

Stature estimation based on hand length and foot length

This study was carried out to estimate the relationship between hand length, foot length and stature using multiple linear regression analyses based on a sample of male and female adult Turks residing in Adana. Measurements of hand length, foot length and stature were taken from 155 adult Turks (80 male, 75 female) aged 17–23 years. The participants were students of the Medical Faculty of Cukurova University. A multiple linear regression model was fitted to the observed data. Stature was taken as the response or dependent variable, hand length and foot length were taken as explanatory variables or regressors. All possible (simple and multiple) linear regression models for each of males, females and both genders together were tested for the best model. The multiple linear regression model for both genders together was found to be the best model with the highest values for the coefficients of determination R2 = 0.861 and R2 adjusted = 0.859, and multiple correlation coefficient R = 0.928
