Morphological characteristics and pulmonary function of naval saboteurs and ground special forces of the armed forces of Montenegro / Características morfológicas y función pulmonar de saboteadores navales y fuerzas especiales terrestres de las fuerzas armadas de Montenegro

SUMMARY: The results of numerous medical and kinesiological studies indicate the existence of differences in pulmonary function in relation to age, body height, and the relationship between certain parameters of body composition. The aim of this study was to determine the state of morphological characteristics and pulmonary function of naval saboteurs and ground Special Forces of the Armed Forces of Montenegro. The sample of participants included 30 naval saboteurs aged 30.3±6 years and 30 members of the ground special forces aged 25.6±5 years. The sample of measuring instruments included 4 indicators each for the evaluation of longitudinal dimensionality, transversal dimensionality, mass and body volume, subcutaneous fat, body composition, and pulmonary function. The central and dispersion parameters of the variables were calculated. The specificities of body composition of the naval saboteurs and members of the ground Special Forces of the AF of Montenegro were determined, while the parameters of lung volume and capacity and the parameters of airway flow indicated an excellent state of their respiratory function. Furthermore, it was determined that the studied members of the armed forces had no individual health risks in the sense of the onset of obesity or obstructive ventilatory defects. The results obtained indicate the need for further studies which would predominantly focus on the impact of individual morphological measurements and parameters of body composition on pulmonary function. This would provide important data both for the armed forces in the sense of improving the training system and the realization of specific tasks, as well as for kinesiology as a science from the aspect of determining certain regularities in the functioning of the human body in specific living and working conditions in the armed forces.

Phenotypic intrapopulation variation in quinoa from the department of Boyacá, Colombia / Variación fenotípica intrapoblacional en quinua en el departamento de Boyacá, Colombia

ABSTRACT Quinoa (Chenopodium quinoa Wild.) is an Andean crop that originated from the Andes of South America, with great agronomic, industrial, pharmaceutical potential and also a great capacity to tolerate adverse environmental factors. In Colombia, more accurately in the Department of Nariño, Cauca, Cundinamarca and Boyacá. Shows great genetic variation, both molecular and morphological, which organization remains poorly documented. In Boyacá, there are few studies on the morphological characterization of cultivated materials, and there is no certified planting material, with farmers planting a mixture of materials. Qualitative and quantitative descriptors and principal component and cluster analyses were used to characterize the structure of the intra-population phenotypic variation in Blanca de Jericó quinoa materials grown in the Department of Boyacá. The principal component analysis explained more than 70 % of the observed variation, with the AP, LP, DP, LHS, and AHS characteristics being more variable. The cluster analysis showed grouping by characteristics, such as AP, panicle color, and the presence of pigmented axillae. Results show that the variance in morpho-phenological traits was concentrated at the intra-population, due to high variation at the inter-individual level. A more efficient selection process should be carried out to find materials or "pure" varieties with higher yields, resistance to biotic and abiotic factors, and adaptation to local conditions, which make quinoa an economically profitable crop in the Boyacá department.

RESUMEN La quinua (Chenopodium quinoa Wild.) es un cultivo andino, originario de los Andes Suramericanos, con gran potencial agronómico, industrial y farmacéutico y también con una gran capacidad para tolerar factores ambientales adversos. En Colombia, actualmente, se cultiva en los departamentos de Nariño, Cauca, Cundinamarca y Boyacá. Presenta una gran variación genética, tanto a nivel molecular como morfológica, la cual, ha sido poco documentada. En Boyacá son pocos los estudios de caracterización morfológica de materiales cultivados y no hay material de siembra certificado, por lo que los agricultores siembran una mezcla de materiales. Descriptores cualitativos y cuantitativos y un análisis de componentes principales y de agrupamiento fueron usados para caracterizar la estructura de la variación fenotípica intrapoblacional de los materiales de quinua Blanca Jericó, que son cultivados en el departamento de Boyacá. El análisis de componentes principales explicó más del 70 % de la variación observada, siendo las características más variables AP, LP, DP, LHS y AHS. El análisis clúster mostró un agrupamiento por características, tales como AP, color de la panícula y presencia de axilas pigmentadas. Los resultados mostraron que la variación en las características morfológicas estaba concentrada dentro de la población, debido a la alta variación, a nivel inter-individual. Se deben llevar a cabo procesos de selección más eficientes para encontrar materiales "puros" o variedades con más altos rendimientos, con resistencia a factores bióticos y abióticos y adaptados a las condiciones locales, para así hacer de la quinua un cultivo económicamente rentable para el departamento de Boyacá.

Blood formed elements of the women with uterine tumors as one of the criterion for assessment of severity of the pathology

The indicators for structural analysis of blood formed elements are prominent in the assessment of pathologies, diagnostics and the degree. Therefore, we aimed to evaluate the ongoing alterations that reflect on the structural characteristics of blood formed elements based on the hormonal imbalance among menopausal women with uterine tumors. Blood samples from the women with benign (n=20), malignant (n=20) uterine tumors, and healthy menopausal women (control, n=20) were used. Enzyme-linked Immunosorbent assay (ELISA) kits were used for the quantitative determination of hormones. The blood formed elements ultrastructure observations were conducted using transmission electron microscope. Compared to control (33.8±0.7 pg/mL), estradiol level was higher in benign (45.7±0.9 pg/mL) and malignant (70.7±3.7 pg/mL) cases (P< 0.001). Similar pattern was noted in testosterone levels [control=0.38±0.03 ng/mL, benign=0.55±0.04 ng/mL (P< 0.01), malignant=1.56±0.14 ng/mL (P< 0.001)] was higher in malignant cases. In contrast, progesterone levels were decreased in the disease cases [control=0.93±0.05 ng/mL, benign=0.44±0.003 ng/mL, malignant=0.31±0.02 ng/ml (P< 0.001)]. Assessments of the morphologic structure of erythrocytes revealed pathological forms of erythrocytes (poikilocytosis) in case of benign, as well as in malignant tumors. particularly target cells (codocytes), hamlet cells, teardrop cells (dacrocytes), sickle cell (drepanocytes) erythrocytes. Using ELISA and transmission electron microscopy our results demonstrate that in case of malignant uterine tumor quantitative/structural changes occur in blood formed elements indicating ongoing alterations in hormonal imbalance. Assessing these changes in structural characteristics would be useful in examining uterine pathologies and subsequent treatment plans

Morphology changes of maxillary molar distalization by clear aligner therapy / Cambios de la morfología en la distalización de molares maxilares mediante terapia con alineadores transparentes

SUMMARY: To evaluate the skeletal, dento-alveolar and soft tissue morphology changes after maxillary molar distalization by clear aligner therapy and identify the significant efficacy of molar distalization,18 patients in conformity with the inclusion criteria were selected. Pre- and post-treatment Cone Beam Computed Tomography (CBCT) were examined to measure the angular and linear parameters. All subjects were completed non-extraction clear aligner treatment by distalizing molars. A paired-t test and independent-samples t-test were performed to observe the difference between before and after treatment and the difference between the first molar and second molar respectively. P-values <0.05 were considered statistically significant. Predicted movement rate was calculated by the formula: (actual movement(mm)/planned movement(mm)) x100%. Most variables of pre- and post-treatment showed no statistical difference(P<0.05), excepting SNA angle (P<0.05) and Upper lip/E-line linear (P<0.01) due to incisor retraction. The first and second molar revealed a translation movement without significant tipping and vertical movement. Clear aligners provided a high predictability (83.44 %) of distalization the maxillary first molar, and 85.14 % of the maxillary second molar. Clear aligners can effectively achieve distal displacement of molars.

RESUMEN: Se seleccionaron 18 pacientes, de acuerdo con los criterios de inclusión, para evaluar los cambios en la morfología esquelética, dentoalveolar y de los tejidos blandos después de la distalización de los molares maxilares, mediante la terapia con alineadores transparentes e así identificar la significativa eficacia de la distalización de los molares. Se examinó a través de tomografía computarizada de haz cónico (CBCT) antes y después del tratamiento para medir los parámetros angulares y lineales. Todos los sujetos completaron el tratamiento con alineadores transparentes sin extracción mediante la distalización de los molares. Se realizó una prueba t pareada y una prueba t de muestras independientes para observar la diferencia entre antes y después del tratamiento y la diferencia entre el primer molar y el segundo molar, respectivamente. Los valores de p<0,05 se consideraron estadísticamente significativos. La tasa de movimiento prevista se calculó mediante la fórmula: (movimiento real (mm)/movimiento planificado (mm)) x 100 %. La mayoría de las variables de pre y postratamiento no mostraron diferencia estadística (P<0,05), excepto el ángulo SNA (P<0,05) y el labio superior/línea E lineal (P<0,01) debido a la retracción del incisivo. El primer y segundo molar revelaron un movimiento de traslación sin inclinación significativa y movimiento vertical. Los alineadores transparentes proporcionaron una alta previsibilidad (83,44 %) de la distalización del primer molar superior y del 85,14 % del segundo molar superior. Los alineadores transparentes pueden lograr efectivamente el desplazamiento distal de los molares.

The effects of the aerobic endurance running program on the morphological characteristics of adolescent girls with different nutritional status / Efectos del programa de carrera de resistencia aeróbica en las características morfológicas de las adolescentes con diferentes estados nutricionales

SUMMARY: This study aimed to explore the effects of a single moderate-intensity aerobic endurance running program on the morphological characteristics of normal-weighted and overweighted female adolescents and whether effects differ between individuals of different nutritional statuses. A total of 47 adolescent girls participated in this randomized controlled trial. Before and after 12 weeks of intervention, measurements were obtained for body height, body mass, BMI, triceps, subscapular, abdominal, thigh, and calf skinfolds, and chest, abdominal, thigh, and calf circumference. The total duration of the program was 12 weeks, with a frequency of 2 hours/week (24 sessions). The individual session lasted 60 minutes, and the intensity ranged from 60 % HRmax to 80 %. The findings from the present study suggest that the 12-week aerobic endurance running program induced changes in morphological characteristics of female adolescents. The significant reductions in body mass and BMI were small for normal-weight adolescents (-2,64 % and -3,48 %) and moderate for overweight adolescents (-4,14 % and -4,36 %) following the experimental program. The magnitude of reductions in the skinfold thickness was small for both groups (triceps, subscapular, abdominal, and calf) and moderate for thigh skinfold and a sum of skinfolds in the overweight group. The reductions in the magnitude of all circular measures were small for both groups. It ranged from - 1.59 % to -2.59 % for normal-weight and from -2.54 % to -3.92 % for overweight adolescents, respectively. Additionally, the effects of the applied program seem more favorable to overweight than normal-weight adolescents. This study's current findings indicate that the 12-week aerobic endurance running program is effective due to improvements in morphological characteristics, body mass, and BMI of female adolescents. Additionally, this study's findings show that applied aerobic endurance running program proved more effective for overweight adolescents.

RESUMEN: Este estudio tuvo como objetivo explorar los efectos de un programa único de carrera de resistencia aeróbica de intensidad moderada sobre las características morfológicas de mujeres adolescentes con peso normal y con sobrepeso y si los efectos difieren entre individuos con diferentes estados nutricionales. Un total de 47 niñas adolescentes participaron en este ensayo controlado aleatorio. Antes y después de 12 semanas de intervención, se obtuvieron mediciones de altura corporal, masa corporal, IMC, tríceps, pliegues cutáneos subescapular, abdominal, muslo y pantorrilla, y circunferencia torácica, abdominal, muslo y pantorrilla. La duración total del programa fue de12 semanas, con una frecuencia de 2 horas/semana (24 sesiones). La sesión individual tuvo una duración de 60 minutos y la intensidad osciló entre el 60 % y el 80 % de la FCmáx. Los hallazgos del presente estudio sugieren que el programa de carrera de resistencia aeróbica de 12 semanas indujo cambios en las características morfológicas de las adolescentes. Las reducciones significativas en la masa corporal y el IMC fueron menores para los adolescentes con peso normal (-2,64 % y -3,48 %) y moderadas para los adolescentes con sobrepeso (-4,14 % y -4,36 %) después del programa experimental. La magnitud de las reducciones en el grosor del pliegue cutáneo fue pequeña para ambos grupos (tríceps, subescapular, abdominal y pantorrilla) y moderada para el pliegue cutáneo del muslo y la suma de los pliegues cutáneos en el grupo con sobrepeso. Las reducciones en la magnitud de todas las medidas circulares fueron pequeñas para ambos grupos. Osciló entre -1,59 % y -2,59 % para normopeso y entre -2,54 % y -3,92 % para adolescentes con sobrepeso, respectivamente. Además, los efectos del programa aplicado parecen más favorables para los adolescentes con sobrepeso que para aquellos de peso normal. Los hallazgos actuales de este estudio indican que el programa de carreras de resistencia aeróbica de 12 semanas es eficaz, debido a las mejoras en las características morfológicas, la masa corporal y el IMC de las adolescentes. Además, los hallazgos de este estudio muestran que el programa de carrera de resistencia aeróbica aplicada demostró ser más efectivo para los adolescentes con sobrepeso.

Value of dual-layer spectral detector CT in differentiating the diagnosis of lung cancer and inflammatory nodules / 中华放射学杂志

Objective:To explore the value of dual-layer spectral detector CT in differentiating the diagnosis of lung cancer and inflammatory nodules.Methods:A total of 92 patients undergoing enhanced chest scan from March 2019 to September 2020 at Renji Hospital, School of Medicine, Shanghai Jiaotong University, were retrospectively enrolled in the study. The conventional CT parameters, spectral CT parameters were measured and the nodules′ morphological characteristics were analyzed. Later the factors with statistical significance were identified as independent variables in a logistic regression model to establish models for predicting malignant nodules. ROC curve was used to assess the diagnostic performance for the conventional CT model, spectral CT parameters and combined model, respectively. Differences in the area under the ROC curve (AUC) were analyzed by the DeLong test.Results:Lobulated sign (42 and 8, respectively, χ2=10.779, P=0.001), short burr sign (41 and 7, respectively, χ2=11.911, P=0.001), pleural indentation sign (45 and 9 respectively, χ2=11.705, P=0.001), vascular convergence sign (35 and 8, respectively, χ2=5.337, P=0.021) and the venous phase iodine concentrations (IC) value [(2.1±0.5) mg/ml, (2.3±0.5) mg/ml, t=-2.464, P=0.016], normalized iodine concentrations (NIC) value (0.40±0.06, 0.45±0.08, t=-6.943, P<0.001), and Z-effective (Z eff) values (8.38±0.21, 8.49±0.19, t=-2.122, P=0.037) were significantly different between the lung cancer group and the inflammatory group, while other CT signs and CT indicators were not significantly different between the lung cancer group and the inflammatory group ( P>0.05). The conventional CT model was established with lobulated sign, short burr sign, pleural indentation sign, vascular convergence sign, and the AUC for differential diagnosis of lung cancer and inflammatory nodules was 0.827. The spectral CT parameter model was established with venous phase IC, venous phase NIC, and venous phase Z eff value, and the AUC for differential diagnosis of lung cancer and inflammatory nodules was 0.899. The conventional CT model combined spectral CT parameter model was established with the significant factors in the univariate analysis, and the AUC for differential diagnosis of lung cancer and inflammatory nodules was 0.925. The AUC of the combined model showed no significant difference from that of the spectral CT parameter model ( Z=1.794, P=0.073). However, AUC of the combined model was significantly higher than that of evaluation based on conventional CT alone ( Z=2.156, P=0.031). Conclusion:Spectral CT parameters combined with conventional CT signs can improve the differential diagnosis efficiency between lung cancer and inflammatory nodules.

Detection of inferior myocardial infarction based on morphological characteristics / 生物医学工程学杂志

Early accurate detection of inferior myocardial infarction is an important way to reduce the mortality from inferior myocardial infarction. Regrading the existing problems in the detection of inferior myocardial infarction, complex model structures and redundant features, this paper proposed a novel inferior myocardial infarction detection algorithm. Firstly, based on the clinic pathological information, the peak and area features of QRS and ST-T wavebands as well as the slope feature of ST waveband were extracted from electrocardiogram (ECG) signals leads Ⅱ, Ⅲ and aVF. In addition, according to individual features and the dispersion between them, we applied genetic algorithm to make judgement and then input the feature with larger degree into support vector machine (SVM) to realize the accurate detection of inferior myocardial infarction. The proposed method in this paper was verified by Physikalisch-Technische Bundesanstalt (PTB) diagnostic electrocardio signal database and the accuracy rate was up to 98.33%. Conforming to the clinical diagnosis and the characteristics of specific changes in inferior myocardial infarction ECG signal, the proposed method can effectively make precise detection of inferior myocardial infarction by morphological features, and therefore is suitable to be applied in portable devices development for clinical promotion.

Sex prediction by analysis of the morphological characteristics of macerated skulls / Predicción sexual mediante análisis de las características morfológicas de cráneos macerados

The skull is a reliable structure for determining the sex of an adult individual; it is generally resistant in adverse conditions, allowing it to be used for the analysis of sexual dimorphism. In the present study we analysed 10 non-metric characteristics of skulls of Brazilian adult individuals in order to: Determine the strength of association between sex and the morphological characteristics of the skull, the morphological characteristic(s) with greatest diagnostic influence for sex, and analyse whether the morphological characteristics of the skull predict sex. The study included 179 macerated skulls of Brazilian adults, (69 female, 110 male). The sex of all the skulls included was identified. The investigators were calibrated prior to analysis and all the evaluations were carried out under blinding. Pearson's Chi-squared test was used. The sensitivity and specificity were analysed and a ROC curve was constructed. Binary logistic regression was carried out. The SPSS v.22 software was used, with a significance threshold of 5 %. All the characteristics analysed presented statistically significant differences (p<0.05). The frontal profile, the superciliary arch and the glabella presented the greatest sensitivity, best balance between sensitivity and specificity and greatest area under curve. The regression model with the frontal profile, superciliary arch and mastoid process was significant [X2(2) = 115,728 p=0.000, R2 Negelkerke=0.657], and presented correct sex classification in 90 % of cases (Males: 87.4 %; Females: 83.1 %). In unknown individuals for whom the skull is present, non-metric analysis of the frontal profile, superciliary arch, mastoid process and glabella can be used as instruments for sex identification.

El cráneo es una estructura confiable para la determinación sexual de un individuo adulto y suele ser resistente en condiciones adversas, por lo que puede ser utilizado para el análisis del dimorfismo sexual. En el presente estudio analizamos 10 características no métricas de cráneos de individuos brasileños adultos a fin de determinar la fuerza de asociación entre el sexo y características morfológicas del cráneo; determinar la(s) característica(s) morfológica(s) con mejor poder para diagnosticar el sexo; y analizar si las características morfológicas del cráneo son previsoras del sexo. Fueron incluidos 179 cráneos macerados de brasileños adultos, (69 femeninos, 110 masculinos). Todos los cráneos incluidos presentaban identificación de sexo. Los investigadores fueron previamente calibrados y todas las evaluaciones fueron realizadas de forma ciega. Se utilizó la prueba de Chicuadrado de Pearson. Se analizó la sensibilidad y especificidad y se construyó una curva ROC. Se realizó regresión logística binaria. Se utilizó el software SPSS v.22, considerando umbral de significación de 5 %. Todas las características analizadas presentaron diferencias estadísticas significativas (p<0,05). El perfil frontal, el arco superciliar y la glabela fueron las características que presentaron mayor sensibilidad, mejor equilibrio sensibilidad/especificidad y mayor area under curve. El modelo de regresión con el perfil frontal, arco superciliar y proceso mastoides fue significativo [X2(2) = 115,728 p=0.000, R2 Negelkerke=0,657], y presentó una clasificación sexual correcta de 90 % (Males; 87,4 %; Females: 83,1 %). En individuos desconocidos en los cuales esté presente el cráneo, el análisis no-métrico del perfil frontal, del arco superciliar, del proceso mastoides y de la glabela pueden ser utilizados como herramienta para identificación sexual.

Digital three-dimensional morphology of cervical joint facet in 7-12-year-old children / 中国组织工程研究

BACKGROUND: Lots of researches by domestic and foreign scholars have confirmed that the asymmetry of facet joint surface or the articular angles might cause the degeneration of the facet joints, and the articular spondylolisthesis. But most of the studies focus on the adult. It has been confirmed that the most common cause of the cervical disease, of the osteoarthritis, of the neurovascular compression or even the paralysis is the pathological changes of facet joint for people as they grow older. There are few studies on the facet joints in children. OBJECTIVE: To explore the cervical joint facet morphology development characteristics and age-related changes by collecting the CT scanning data of cervical vertebrae in children aged 7-12 years old, three-dimensional reconstruction and cervical facet joint morphology measurement and analysis. METHODS: Through collecting the data of multi-layers spiral CT scan of children in the First Affiliated Hospital and Second Affiliated Hospital of Inner Mongolia Medical University and Inner Mongolia International Mongolian Hospital from September 2013 to September 2015, 99 cases of cervical structures were selected. Then DICOM format of original data were imported in Mimics software for three-dimensional reconstruction. Morphological measurement was conducted on the three-dimensional model. The study was approved by the Ethical Committee of Inner Mongolia Medical University on March 11, 2015, approval No. YKD2015049. RESULTS AND CONCLUSION: (1) The length of children cervical joint facet was on a rise with age and a decreasing trend with ordinal number of vertebrae. (2) The width of children middle upper cervical joint facet showed “V” type. The width of children lower cervical joint facet increased with the increase of vertebral order. (3) The trend of distance between articular tubercles was “spike” shape. (4) The coronal angle of joint facet presented to be “V” shape. (5) The sagittal angle of joint facet was in inverted “V” shape. (6) In summary, there is no asymmetry of articular process in the morphological characteristics of cervical facet joints in 7-12-year-old children.

BACKGROUND: A large amount of literature has been published on the vertebral pedicle morphology at thoracolumbar segments in adults, but little is known about the morphology of pedicles in adolescents, especially in Asian populations. Adolescent spine disorders are increasing and there are few precise morphological studies. OBJECTIVE: To investigate the anatomy of lumbar vertebrae of adolescents aged 12-15 years in Inner Mongolia, provide detailed information for pedicle screw placement, determine the safe and appropriate screw size, and provide data reference for screw size design. METHODS: The normal chest and lumbar CT data of 65 adolescents aged 12-15 years in Inner Mongolia were collected and divided into two groups, 31 cases of 12-13 years old, and 34 cases of 14-15 years old. The raw data of the thoracic and lumbar vertebrae images scanned continuously were imported into Mimics 21.0 for analysis and measurement in DICOM format. Pedicle width, pedicle height, transverse diameter, longitudinal diameter, pedicle length, pedicle outer declination, pedicle maximum external angle, pedicle head inclination, and pedicle area were measured. RESULTS AND CONCLUSION: (1) The L1-L4 pedicle width in the two groups was less than pedicle height, and pedicle width and pedicle height at L5 were similar. The pedicle width determined the screw diameter, which was larger in males than in females. (2) In 12-13 years old, the screw length at L1-L5 was between 40-45 mm. In 14-15 years old, the screw length was between 40-45 mm at L1-L4, and 45-50 mm at L5. (3) The laws of the two groups were the same. The transverse diameter of spinal canal was significantly larger than longitudinal diameter of spinal canal (P < 0.05), and there was no significant difference between men and women. (4) The transverse pedicle angle: In 12-13 years old, L1-L2 had small change, L2-L5 gradually increased; in 14-15 years old, L1-L5 gradually increased; it is larger in males than in females in both groups. (5) Maximum transverse pedicle angle: The two groups had the same law. L1-L5 gradually increased, and decreased with age. There was no significant difference between left and right sides and sexes. There was significant difference among different ages (P < 0.05). (6) The sagittal pedicle angle: The in 12-13 years old, 3°-8°; in 14-15 years old, 0°-5°.

Isolation and characterization of Pyricularia oryzae isolated from lowland rice in Sarawak, Malaysian Borneo

@#Aims: Rice blast disease caused by Pyricularia oryzae is one of the major biotic diseases of rice in Sarawak, Malaysian Borneo. This study aims to isolate and characterize rice blast fungus obtained from infected leaf collected from four different divisions in Sarawak, viz, Miri, Serian, Sri Aman, and Kuching. Methodology and results: Twelve succeeded isolates were pre-identified as P. oryzae by morphological characteristics of spores, followed by verification through (internal transcribed spacer) ITS sequencing. The isolates were evaluated for morphological characteristics, growth rate and sporulation rate, which were grown on two types of media, (filtered oatmeal agar) FOMA and (potato dextrose agar) PDA. Morphological characterization showed that the colony surface of the different isolates varied from smooth and fluffy to rough and flattened mycelia; some were with the present of concentric rings, and some with aerial mycelia. The growth rate and sporulation rate of each isolate varied based on types of media used. Most of the isolates grew faster on PDA than on FOMA but produced higher number of spores on FOMA as compared to PDA. Conclusion, significance and impact of study: This preliminary study showed that there were variations observed based on morphological and physiological characterization for the different isolates collected in Sarawak, Malaysian Borneo. This study is the first step towards understanding variation in the population of P. oryzae from Sarawak.

Effect of soft tissue thickness on the morphology of lip in orthodontic treatment / Efecto del grosor del tejido blando en la morfología del labio en el tratamiento de ortodoncia

The aim of this study was to evaluate the effect of soft tissue thickness of upper lip on lip retraction in orthodonticaltreated females and identify the ratio of maxillary incisor retraction to upper lip retraction. Pre- and post-treatment lateral cephalograms of 100 adults were examined to measure the lip thickness in upper lip and establish the classification standard. All subjects were treated with 4 first premolar extractions followed by upper central incisors retraction. Pre- and post-treatment lateral cephalograms of 19 patients were reviewed to determine the changes of the upper lip and incisor positions through landmarks displacement. An independent-samples t test and one-way analysis of variance were performed. The correlations between maxillary incisor retraction and upper lip retraction were explored by the Pearson correlation method. P-values<0.05 were considered statistically significant. The lip thickness of adult male patients was greater than that of adult female patients. The average ratio of maxillary incisor retraction to upper lip repositioning was 1.6:1,1.9:1 and 2.2:1 in the thin lips group, normal lips group and thick lips group, respectively. Gender differences exist in the thickness of upper lip. Horizontal changes of the maxillary incisor showed a significant correlation to horizontal changes of the upper lip (P<0.001).There were negative correlations between the thickness of upper lip and the ratio between change in maxillary incisor protrusion and change in upper lip protrusion.
