Types Of Information

Dermatoglyphic characteristics for identification of sex play an important role in forensic and medico-legal purposes. Hence, it considered to be the most precise and reliable indicators for personal and gender identification. Such types of information on Bengali speaking Hindu population are very scanty. This was tempted the present authors to assess the sex-wise variation of digital dermatoglyphic traits in a sample from West Bengal, India. A total 168 participants were recruited to obtain basic information and fingertip impression of the participants. Impressions were taken by using Ink method (Calcutta Ink) and examined with hand-lens. The mean age for male participants was 31.30 ±16.13 and for females it was 32.11±13.30. The loop pattern is observed more frequent (46.13%) compared to whorl (36.25%), arch (10.89%) and composite (6.72%). Females have a more loop (47.84%) and arch (12.26%) patterns than males (43.48% and 8.79% respectively. The whorl (39.85%) and composite (7.88%) patterns are observed more frequently in males as compared to females (33.92% and 5.98% respectively). Furuhata’s Index is more frequent in males (91.64) than females (70.9) but both the Dankmeijer’s and Poll’s Index are higher in females (36.13 and 25.61 respectively) than males (22.05 and 20.21 respectively). However, in case of Pattern Intensity Index there is slightly a sex difference for males and females (12.32 and 11.57 respectively). It was concluded that differences in the finger print pattern, combinations and indices can be used as an important tool for the determination of sex in medico-legal and forensic purposes.

SummaryThe plasma tissue factor (TF) concentration was correlated to factor VII concentration (FVIIag) and factor VII activity (FVIIc) in 498 healthy volunteers ranging in age from 17 to 64 years. Immunoassays using monoclonal antibodies (mAbs) were developed for the determination of TF and FVIIag in plasma. The mAbs and the test systems were characterized. The mean value of the TF concentration was 172 ± 135 pg/ml. TF showed no age- and gender-related differences. For the total population, FVIIc, determined by a clotting test, was 110 ± 15% and the factor VIlag was 0.77 ± 0.19 μg/ml. FVII activity was significantly increased with age, whereas the concentration demonstrated no correlation to age in this population. FVII concentration is highly correlated with the activity as measured by clotting assay using rabbit thromboplastin. The ratio between FVIIc and FVIIag was not age-dependent, but demonstrated a significant difference between men and women. Between TF and FVII we could not detect a correlation.

The aim of this study was to reveal and to describe the structure of the verbalized concept of «flirting». The main method of the research was a psycholinguistic experiment. The sample comprised 400 young people (aged 18-35), males and females being equally represented. The concept of «flirting» is represented by eleven clusters, four of them are core: «verbal and non-verbal ways of communication», «forms and ways of interaction», «emotions, feelings, states», and «gender». Two psycholinguistic meanings of «flirting» concept were described: «The stage of courtship with no intimate relation», «Sexual relationship». The semantic content of the concept of «flirting» does not depend on gender identification. The general attitude of the respondents to the stimulus «lightness» is quite positive.

Introduction: Aircrew are repetitively exposed to positive Gz acceleration in fighter flying. Factors affecting +Gz tolerance vary among individuals and are determined by both modifiable and non-modifiable factors. Some of the non-modifiable factors influencing +Gz tolerance are age, gender, and height. The present study was undertaken to understand the relationship of these variables with relaxed +Gz tolerance. Material and Methods: The study involved a retrospective analysis of existing database of the high-performance human centrifuge at the Institute of Aerospace Medicine. Relevant data from 70 non-aircrew subjects were included for the study. Of these, 39 were male and 31 were female. The age and height varied from 27 to 38 years and 157 to 187 cm, respectively. The data were analyzed using Microsoft Office Excel® to find the correlation between age and height with relaxed +Gz tolerance. Relaxed +Gz tolerance of men and women was compared using unpaired t-test. Significance was set at P < 0.05. Results: The mean age, height, and relaxed +Gz tolerance of males were found to be 30.25 ± 4.3 years, 172.58 ± 6.5 cm, and 4.89 ± 0.67G, respectively, whereas those of females were 27.28 ± 3.36 years, 158.46 ± 6.78 cm, and 4.4 ± 0.85G, respectively. In both males and females, age and height showed no correlation with relaxed +Gz tolerance. However, the relaxed +Gz tolerance was found to be higher in males and this difference was statistically different (P = 0.008). Conclusion: Age and height showed no correlation with relaxed +Gz tolerance in both males and females nonaircrew subjects. Males exhibited a statistically significant, higher relaxed +Gz tolerance as compared to females.

ABSTRACT Objective: The present study is intended to add a new parameter that would be useful in orthodontic clinical evaluation, treatment planning, and determination of vertical dimension (at occlusion). Materials and Methods: Standardized videographic recording of 79 subjects during posed smile was captured. Each video was then cut into 30 photos using the free studio software. The widest commissure-to-commissure posed smile frame (posed smile width [SW]) was selected as one of 10 or more frames showing an identical smile. Lower third of the face is measured from subnasale to soft tissue menton using a digital vernier caliper. Two values were then compared. Ratio between lower facial height and posed SW was calculated. Results: The co-relation between smiling width and lower facial height was found to be statistically significant (P < 0.01). The ratio of lower facial height and smiling width was calculated as 1.0016 with a standard deviation (SD) = 0.04 in males and 1.0301 with an SD = 0.07 in females. The difference between the mean lower facial height in males and females was statistically significant with a t = 10.231 and P = 0.000. The difference between the mean smiling width in males and females was also statistically significant with a t = 5.653 and P = 0.000. Conclusion: In class I subjects with pleasing appearance, normal facial proportions, normal overjet and overbite, and average Frankfort mandibular angle, the lower facial height (subnasale to soft tissue menton) is equal to posed SW.

The determination of the mean normal haemoglobin concentration has re ceived more attention in America than in this country. Recently Price-Jones (1931) has compared the values in London with those found in America. He used the Haldane haemoglobinometer and his results are as accurate as is possible having regard to the method employed. In America his results were 3 percent. above those of the Haldane gas analysis apparatus (1901) by which theclinical instrument is supposed to be calibrated. Twenty comparisons were made in America and showed that the Haldane gas apparatus gave results averaging 2·6 per cent. below those of the Van Slyke apparatus. Price-Jones considers this to have no statistical significance. From the standpoint of experimental accuracy the difference is appreciable, as all methods for the measurement of oxygen combined with Hb are essentially pragmatic.

High Order Aberrations

Introduction: Wavefront sensing technology has emerged as a means to advance our understanding of high-order aberrations of the human eye. Purpose: To evaluate the differences in ocular high-order aberrations between males and females and the distribution of high-order aberrations in males and females. Subjects and methods: 3,597 eyes (1,029 female and 2,568 male) of 1,874 patients who obtained wavefront measurements performed using the VISX Wavescan device were included in this study. Mean RMS (root mean square) values of high-order aberrations (HOAs) and the mean of each Zernike polynomial from the second to the sixth order were calculated from multiple scans of each eye. Analysis was performed to assess the association between HOAs and gender, and symmetry of HOAs between eyes in both males and females. Results: Overall HOA did not differ significantly between males and females (p= 0.93). Overall HOA did not differ between left eyes (p=0.852) or right eyes (p=0.76). Individual Zernike polynomials did reveal a significant difference between male and female eyes: Z14 (Tetrafoil x, p=.036); Z16 (Secondary Trefoil y, p=0.015); Z24 (Secondary Spherical, p=0.003); Z25 (Tertiary Astigmatism x, p=0.010); and Z26 (Secondary Tetrafoil x, p=0.004). Conclusion: Overall HOA does not differ between the genders; however, individual HOA Zernike terms do demonstrate statistically significant differences between males and females. This is the first such study to describe these differences. The clinical significance of these differences has yet to be determined.

Cephalic index is an important feature that characterizes different races. The study aimed at comparing the cephalic indices between the two genders and to determine the stature among Okun and Ebira ethnic groups in Nigeria. The subjects were measured for cephalic length, breadth and subject height and the cephalic indices were calculated by dividing the cephalic breadth by cephalic length, and then multiply by 100. 844 subjects of Okun and Ebira origin of Kogi state were measured, 211 males and 211 females for each tribe were measured. Fischer’s formula was used to determine the sample size because the population size is > 10,000. The cephalic breadth and length was measured using a spreading caliper and the subject height was measured with a stadiometer. The data was analyzed using Pearson’s Chisquare analysis test for association, trends and distribution difference of the pattern (confidence level at 95%). The mean cephalic indices of both Okun and Ebira ethnic group were >75 and >70 which belongs to mesocephalic and doliocephalic group respectively. There were significant differences in cephalic indices between both ethnic groups (p<0.001). There was no significant difference in cephalic indices between males and females of each ethnic group. Stature was better predicted from cephalic indices for Ebira males (r= 0.386) when compared to the Ebira females (r= 0.127), Okun males (r= 0.296) and Okun females (r = 0.268). All predictions were significant except for Ebira females.Keywords: mesocephalic, doliocephalic, cephalic indices, stature, sex

Abstract Background Forensic odontology deals with age, sex, and race determination of the deceased at crime scenes, disasters, or natural calamities. Studies regarding the role of secondary dentin in age estimation have been documented on a several occasions in the literature but use of secondary dentin in gender predilection has not yet been documented. So, the present study was aimed at using the secondary dentin as a diagnostic tool in gender predilection. Materials and Methods The study included a total of 20 samples (10 males and 10 females). Extracted teeth were collected and placed in 10% neutral buffered formalin solution. The sections were ground on Arkansas stone until the appropriate thickness of the ground sections was achieved. The freshly prepared ground section was mounted on a slide using DPX mounting media. Ground sections were visualized under a microscope and the thickness of secondary dentine was measured using the image analysis software. Results The data were collected and subjected to group statistics. The secondary dentin thickness of all the samples, males and females, was measured. It was observed in our study that the mean thickness of secondary dentin was more in male samples (0.2970) with the standard deviation of 0.01494, as compared with that of females where the mean thickness was found to be 0.1970 with the standard deviation of 0.02058. Conclusion This study has shown that variation in secondary dentin thickness does exist between male and female groups. This criterion can be considered as an aid for gender determination in the future.

Introduction: In the last few decades data on the incidence of acute myocardial infarction are not available in Hungary. Aim: The aim of the authors was to define the incidence of myocardial infarction using the Hungarian Infarction Registry according to the number of in- and out-of-hospital cases in five districts of the capital (districts II, III, IX, X and XVII) and Szabolcs-Szatmár-Bereg county. Method: Besides using the Hungarian Infarction Registry, databases of the National Public Health and Medical Officer Service and that of the Hungarian Central Statistical Office were used in order to define the incidence of prehospital cases, according to the regulations presented in an earlier proposal of the Data Protection Ombudsman of Hungary. Results: For 10 000 residents the incidence of myocardial infarction in the capital was 28.63 in males and 16.21 in females, while in Szabolcs-Szatmár-Bereg county the mean incidence was 32.49 for males and 18.59 for females. The mean incidence of myocardial infarction in the five districts of the capital in males and females did not differ from the mean values of Szabolcs-Szatmár-Bereg county. When comparing the incidence values in different districts of the capital to the countryside, the Szabolcs-Szatmár-Bereg county had significantly higher values for both males and females compared to districts II and III of the capital, while in district X the incidence of myocardial infarction in males was significantly lower compared to the values in the countryside. Conclusions: Using the mean incidence results projected to the capital and countryside population according to age and gender, 20 000 new myocardial infarction cases might be expected per year in Hungary.

This study aims to estimate an adult-equivalent scale for calorie requirements and to determine the differences between adult-equivalent and per capita measurements of calorie availability in the Brazilian population. The study used data from the 2002-2003 Brazilian Household Budget Survey. The calorie requirement for a reference adult individual was based on the mean requirements for adult males and females (2,550kcal/day). The conversion factors were defined as the ratios between the calorie requirements for each age group and gender and that of the reference adult. The adult-equivalent calorie availability levels were higher than the per capita levels, with the largest differences in rural and low-income households. Differences in household calorie availability varied from 22kcal/day (households with adults and an adolescent) to 428kcal/day (households with elderly individuals), thus showing that per capital measurements can underestimate the real calorie availability, since they overlook differences in household composition.
