Abstract Introduction Palatal rugae or plica palatine are the finger prints of the oral cavity and the arch length varies between males and females. These two parameters constitute an integral part of the anthropometric studies in the realms of dentistry as well as forensic odontology. The aim of this study was to assess whether any relationship existed between the upper arch length and the rugae pattern and whether these two parameters showed any gender differentiation. Materials and Methods The sample consisted of upper and lower study models of 60 subjects (30 males and 30 females). Arch lengths were measured using a brass wire and rugae were traced on the dental casts and assessed by applying the Thomas and Kotze classification (1983). The data collected was subjected to statistical analysis. Results The results showed that the maxillary and mandibular arch length dimensions were higher in males than in females; however, the differences were found to be statistically insignificant. The assessment of rugae pattern showed that the male subjects had a higher number of rugae. The differences in rugae pattern distribution for male and female subjects were found to be statistically significant. Conclusion The palatal rugae pattern and maxillary arch length can be used as an additional method in differentiating gender between human population groups.

Indonesia as a disaster-prone area allowed casualty in large numbers and need immediate identification. One way to identify it was the use forensic odontology. Palatal rugae pattern has been suggested as an alternative method in forensic odontology to determine gender in all sorts of ethnic and population. The aim of this study was to know the difference of palatal rugae pattern between males and females in Minang ethnic. This study used descriptive analytics with cross sectional approach. The study sample compromised 122 dental stone casts of Minang ethnic, 61 males and 61 females wih range 15-19 years.  The method rugae identification was based classification of Thomas and Kotze. The data were analyzed by Mann-Whitney test. The most predominant palatal rugae pattern in Minang ethnic are wavy and primary rugae. The Minang males were predominantly wavy, followed by straight, curve, unification, and circular. The Minang females were predominantly wavy, followed by curve, straight, and unification. There was a significant (p<0,05) sex difference in the circular type which was higher in males. Palatal rugae pattern can be used as adjunct to sex differentiation between males and females of ethnic Minang in forensic odontology. Key words : Forensic odontology, analysis of rugae palatal, gender, Minang ethnic

Introduction: The palatal rugae are anatomical folds or wrinkles located on the anterior third of the palate behind the incisive papilla on each side of the palatal raphe. The rugae patterns have been studied for various purposes mainly in the field of anthropology, comparative anatomy, genetics, prosthodontics, orthodontics and forensic odontology. This study is aimed to determine the difference in number and pattern of palatal rugae in males and females. Methods: This is a prospective study in which maxillary impressions of 50 volunteers, 25 males and 25 females were taken and the casts prepared. The boundaries of the rugae were marked with a HB pencil and were observed with a magnifying glass following the classification used by Kapali, et al, (1997). Association between rugae number and sex and rugae shape and sex were tested using two sample unpaired t test. Results: The study revealed significant difference in the pattern of converge rugae which were found to be higher in females than males, however, no statistical significant difference was found in the number of rugae between the two sexes. Conclusions: The rugae pattern can be an additional method of differentiation between the males and females in conjunction with the other methods used in forensic sciences. Keywords: forensic science; human identification; palatal rugae.

Objectives: To evaluate the individuality of palatal rugae patten and correlate them in males and females in different age groups by using Trobo’s classification. Study Design: Cross Sectional. Setting: Department of Prosthodontics, Dow Dental College, Dow University of Health Sciences. Period: September 2019 to January 2020. Material & Methods: This study comprised of ninety-four participants with equal number of males and females from 10 years to 70 years, visiting the Prosthodontic department. Study casts included were free of dental abnormality, trauma, malocclusion, orthodontic problems, and deformity in palatal rugae area. Sample size was calculated from software name openepi.com with 95% confidence interval. Data was tabulated and SPSS version 22.0 was used to identify the results. Results: Frequency distribution was performed among age groups in which second group (20 to 39 years) has highest frequency with 52 in number. The cross tab between age group and type of rugae was made which showed group II, having age between 20 to 39 years, had the highest number of palatal rugae configurations amongst all. Conclusion: Sinuous or type E was the predominant type of palatal rugae found in this study. The study did not show significant difference in gender, however number of rugae were found consistently more in young adults with propensity towards individuality. Their use can thus be justified for dental identification in forensic odontology.

Introduction: Cheiloscopy is considered as an emerging method in forensic odontology for identification of gender. There are several methods given in literature to identify the lip print types. Digital photographs can be used to study the lip prints for gender identification. Objective: The aim of the study was to identify the predominant lip print pattern in males and females by using digital photographs. Methods: This analytical cross-sectional study included 206 subjects, comprising 103 males and 103 females. Digital photographs were used to identify the lip print patterns. The classification given by Suzuki and Tsuchihashi was used to further classify the lip patterns. Kappa test was applied to check for inter observer variation. Statistical analysis was done using SPSS version 23. The association between gender and lip print type was tested by Chi square test. Results: Type I was the most common lip print followed by Type I’. Type V was the least common lip print followed by Type IV. Type I and Type II were the most common pattern in females and males respectively and these differences were found to be statistically significant (p<0.01). Conclusion: Digital photographs are very useful for identification of lip print pattern. The variation in lip print pattern among males and females can be taken as an aid in gender determination.

Objective: To determine the number and pattern of palatal rugae in Nepalese subjects and to find the association of gender with the number and pattern of palatal rugae. Materials & Method: 200 Nepalese subjects comprising of 100 male and 100 female were randomly selected and their maxillary casts were examined for the palatal rugae length applying the classification proposed by Thomas and Kotze and palatal rugae pattern was recorded using the classification given by Kapali. Statistical analysis using Student t-test was applied for comparing the number of palatal rugae between right and left sides. Chi square test was used to find the association between gender and number of rugae as well as the pattern. Result: The study demonstrated that the mean number of primary palatal rugae on left side was predominant, similarly wavy pattern was the most predominant in Nepalese subjects. No statistical significant difference was noticed in the palatal rugae number and pattern between the gender groups. Conclusion: The study found predominant palatal form in Nepalese subjects which might have superior effectiveness in population differentiation and may be used as an effective tool in forensic odontology identification.

The resting content and use of myocellular triacylglycerol (MCTG) during 90 min of submaximal exercise [60% of peak oxygen uptake (V˙o 2 peak)] were studied in 21 eumenorrheic female and 21 male subjects at different training levels [untrained (UT), moderately trained (MT), and endurance trained (END)]. Males and females were matched according to theirV˙o 2 peak expressed relative to lean body mass, physical activity level, and training history. All subjects ingested the same controlled diet for 8 days, and all females were tested in the midfollicular phase of the menstrual cycle. Resting MCTG, measured with the muscle biopsy technique, averaged 48.4 ± 4.2, 48.5 ± 8.4, and 52.2 ± 5.8 mmol/kg dry wt in UT, MT, and END females, respectively, and 34.1 ± 4.9, 31.6 ± 3.3, and 38.4 ± 3.0 mmol/kg dry wt in UT, MT, and END males, respectively ( P < 0.001, females vs. males in all groups). Exercise decreased MCTG content in the female subjects by an average of 25%, regardless of training status, whereas in the male groups MCTG content was unaffected by exercise. The arterial plasma insulin concentration was higher ( P < 0.05) and the arterial plasma epinephrine concentration was lower ( P < 0.05) in the females than in the males at rest and during exercise. MCTG use was correlated to the resting concentration of MCTG ( P < 0.001). We conclude that resting content and use of MCTG during exercise are related to gender and furthermore are independent of training status.

28 males and 28 females from general psychology classes completed several attitudinal questionnaires, including the Women as Managers Scale and the Attitudes Toward Women Scale. In a later experimental session, subjects viewed a 10-min. video tape that contained either a male or a female directing a mixed-sex triad on a dominoes design task. The script for the leaders and the performance of the groups were identical in each instance. Following the viewing of the video tape, subjects were given questionnaires pertaining to the leader's and the group's performance, characteristics of the leader and the group, and attribution for the outcome on the task. Results indicated that males endorse a more conservative role for females, particularly in management roles, than do females. Female subjects generally evaluated female leaders positively, while male subjects evaluated male leaders positively.

Analytical Variation

1. Plasma aspartate transaminase and alkaline phosphatase activities were measured weekly for approximately 30 weeks in a group of healthy males and females. 2. The magnitude of variation of the enzyme activities within any individual was studied with respect to four criteria: (a) the individual's normal range, (b) the normal range calculated for each sex separately, (c) the clinically accepted normal ranges, (d) the distribution of a derived term which excluded the variation of the predominant enzyme activities between individuals, and the between-batch variation. 3. The main conclusions were: (a) Normal variation for both these enzymes is small. (b) Most of the variability is contributed by analytical variation. Within-individual variation is very small, this applying particularly to the male subjects' activity of alkaline phosphatase, and the aspartate transaminase activity of female subjects. (c) Elevation of the two enzyme activities above clinical normal ranges was infrequent, never of great magnitude, and occurred almost exclusively in males. When elevations of enzyme activity occurred, they tended to be associated either with particular males, or to occur on certain weeks. (d) When the latter effects were allowed for, and a new set of criteria calculated, the resulting ‘abnormal’ values now appeared to be more randomly distributed.
