The development and structure of the chimpanzee mandible. (1/77)

The sites of growth and remodeling, and the associated changes in cortical bone structure, have been studied in the chimpanzee mandible and compared with those previously reported in the human and macaque mandibles. The location of the principal sites of growth, and the distribution of the areas of deposition and resorption in the ramus, were found to be similar in all three species. In the chimpanzee, unlike Man, the bone being deposited at the condyle, posterior border of the ramus and coronoid process was plexiform in nature, indicating very rapid growth. The pattern of remodeling in the mandibular body, on the other hand, showed marked species differences at the chin and on the submandibular lingual surface, which account for the contrasts seen in the adult morphology of these regions. Although the pattern of distribution of cortical densities differed from that of surface remodeling, the information they give is complementary in analysing bone growth. The densest regions were found to coincide with sites of consistent lamellar deposition, while the least dense regions were those where plexiform bone was formed. Areas where remodeling led to the greatest reorientation of bone tissue within the cortex showed the greatest disparity between the two patterns.  (+info)

Delayed dental age in boys with constitutionally delayed puberty. (2/77)

It was the purpose of this study to evaluate dental age in boys with delayed puberty and to compare them with a group of normal, healthy boys. The study group consisted of eight boys with constitutional delay of growth and puberty (CDGP), older than 14 years, and with a testis volume smaller than 4 ml. The control group comprised 38 normal, healthy boys, aged between 12.4 and 14.3 years. Dental age was assessed using the Demirjian method and, on the basis of this evaluation, a dental delay score (i.e. dental age minus chronological age) was calculated in the CDGP and the control group. It was found that Demirjian's dental age assessment is a valid method for scoring dental age in Belgian boys between 12 and 14 years of age, and that CDGP boys showed a significant delay in dental development compared with normal boys (P = 0.0085). This study revealed a significant retardation in dental maturation of boys with CDGP.  (+info)

A comparison of the USDA ossification-based maturity system to a system based on dentition. (3/77)

Two studies using commercially fed cattle were conducted to determine the relationship of the USDA bone ossification-based maturity system to one based on the number of permanent incisors present at slaughter. These studies showed that 91.5 to 100% of cattle with zero permanent incisors (< 23.8 mo of age), 89.1 to 97.5% of cattle with two permanent incisors (23.8 to 30.4 mo of age), 75 to 82.2% of cattle with four permanent incisors (30.4 to 38.0 mo of age), 64 to 72.5% of cattle with six permanent incisors (38.0 to 45.3 mo of age), and 40% of cattle with eight permanent incisors (> 45.3 mo of age) were graded as A maturity by the USDA maturity classification system. Kappa tests revealed no statistical relationship between the dentition- and skeletal ossification-based maturity systems. Dentition-based maturity agreed with ossification/lean maturity for only 162 of 1,264 carcasses in Exp. 1 and only 54 of 200 carcasses in Exp. 2. Cattle with two, four, six, or eight permanent incisors were classified in more youthful categories of USDA bone ossification/lean maturity than they should have been. Male cattle were more likely to be misclassified into a younger age category by the USDA system than were female cattle. It seems that determining physiological maturity by number of permanent incisors rather than by the current USDA method of subjectively evaluating skeletal and lean maturity may prove to be a more accurate technique of sorting beef carcasses into less-variable age groups.  (+info)

Daily incremental lines in sika deer (Cervus nippon) dentine. (4/77)

This work was designed to observe the dentine incremental lines of the sika deer (Cervus nippon) fawns and to investigate their periodicity using the chronological labeling method with fluorochromes. The incremental lines were observed in decalcified specimens stained by Bodian's silver technique, and the fluorescence-labeled lines were observed in undecalcified and ground specimens. In the silver stained specimens, there were two types of lines, deeply stained thick lines and faintly stained minute regular incremental lines. The intervals and staining intensities of the deeply stained thick lines were very similar to those of the fluorescence-labeled lines in the ground specimens obtained from the same tooth, and hence, it appeared that the both lines were identical. The number of minute incremental lines between the deeply stained thick lines was the same as that of days between the time when each fluorescent labeling injection was made. Therefore, it seemed that each minute incremental line was formed each day. The possibility of age estimation in days using diurnal dentine increments was discussed.  (+info)

Cleft type and Angle's classification of malocclusion in Korean cleft patients. (5/77)

This study was performed to investigate the contributing factors, such as cleft type, side of cleft, patient's age, and gender, associated with Angle's classification of malocclusion in Korean cleft patients. The records of 250 cleft patients (175 males, 75 females) who attended the Department of Orthodontics, Seoul National University Dental Hospital between 1988 and 1999 were examined. The percentages of subjects with cleft lip (CL), cleft lip and alveolus (CLA), cleft palate (CP), and cleft lip and palate (CLP) were 7.6, 19.2, 9.6, and 63.6, respectively. The overall distributions of unilateral and bilateral clefts were 76 and 24 per cent, respectively. The overall percentages of Class I, II, and III malocclusions were 18.5, 8.8, and 72.7. The frequency of Class III malocclusions was most prevalent in all age groups. Bivariate analysis showed that whilst gender was not significant, the type of cleft significantly influenced the development of a Class III malocclusion (P < 0.01). Using logistic regression analysis, subjects in the CP (P < 0.05) and CLP groups (P < 0.01) were 3.9 and 5.5 times more likely to have a Class III malocclusion than those in the CL group. There was, however, no statistical difference in the prevalence of a Class III malocclusion between the CL and the CLA groups (P > 0.05). When the degree of cleft involvement in the palate increased, so did the predominance of a Class III malocclusion.  (+info)

Forensic odontology: the roles and responsibilities of the dentist. (6/77)

Dentistry has much to offer law enforcement in the detection and solution of crime or in civil proceedings. Forensic dental fieldwork requires an interdisciplinary knowledge of dental science. Most often the role of the forensic odontologist is to establish a person's identity. Teeth, with their physiologic variations, pathoses and effects of therapy, record information that remains throughout life and beyond. The teeth may also be used as weapons and, under certain circumstances, may leave information about the identity of the biter. Forensic odontology has an important role in the recognition of abuse among persons of all ages. Dental professionals have a major role to play in keeping accurate dental records and providing all necessary information so that legal authorities may recognize malpractice, negligence, fraud or abuse, and identify unknown humans.  (+info)

An Early Pleistocene hominin mandible from Atapuerca-TD6, Spain. (7/77)

We present a mandible recovered in 2003 from the Aurora Stratum of the TD6 level of the Gran Dolina site (Sierra de Atapuerca, northern Spain). The specimen, catalogued as ATD6-96, adds to the hominin sample recovered from this site in 1994-1996, and assigned to Homo antecessor. ATD6-96 is the left half of a gracile mandible belonging to a probably female adult individual with premolars and molars in place. This mandible shows a primitive structural pattern shared with all African and Asian Homo species. However, it is small and exhibits a remarkable gracility, a trait shared only with the Early and Middle Pleistocene Chinese hominins. Furthermore, none of the mandibular features considered apomorphic in the European Middle and Early Upper Pleistocene hominin lineage are present in ATD6-96. This evidence reinforces the taxonomic identity of H. antecessor and is consistent with the hypothesis of a close relationship between this species and Homo sapiens.  (+info)

Dental age in Dutch children. (8/77)

Dental age was studied in a sample of 451 Dutch children (226 boys and 225 girls) according to the method of Demirjian. They were born between 1972 and 1993 and were between 3 and 17 years of age at the time a dental pantomogram (DPT) was obtained. All children were placed in the age group closest to their chronological age. All 451 DPTs were scored by one examiner. A subset of 52 DPTs was scored by a second examiner and the intra-class correlation coefficient (ICC) and Cohen's kappa were calculated. The ICC was 0.99 and Cohen's kappa 0.68. Boys and girls were analysed separately.A significant difference was found between chronological age and dental age. On average, the Dutch boys were 0.4 years and the girls 0.6 years ahead of the French-Canadian children analysed by Demirjian. Therefore, the French-Canadian standards were not considered suitable for Dutch children. New graphs for the Dutch population were constructed using a logistic curve with the equation Y = 100*{1/(1 + e(-alpha(x - x0)))} as a basis. The 90 per cent confidence interval was calculated. To determine whether the logistic curve was correct, a residual analysis was carried out and scatter plots of the differences were made. The explained variance was 93.9 per cent for the boys and 94.8 per cent for the girls. Both the residual analysis and the scatter plots indicated that the logistic curve was appropriate for use with Dutch children. In addition to the graphs, tables were produced which transfer the maturity scores calculated by the method of Demirjian into Dutch dental age.  (+info)

Age estimation is required for forensic cases such as minors without documentation and age disputed asylum seekers. Cervical vertebral maturation (CVM) is a potential method to estimate age, particularly when third molars are mature or absent. The aim of this study was to assess the accuracy of estimating age by maturation of the cervical vertebra, the mandibular second (M2) and third (M3) molars in a group of males. The sample consisted of lateral cephalograms of 60 boys from the Bolton-Brush online collection and 53 from Burlington online collection aged 10 to 15 years. CVM age was calculated from age category and mean age and transition age of CVM stages, calculated from raw data of 69 boys (aged 9 to 15 years) in Lamparski (1972). Dental age was calculated using mandibular second and third molar stages from Liversidge (2009). The mean difference and absolute mean difference between CVM age and dental ages and chronological ages was calculated. CVM and molar tooth stage assessment reliability ...

The aim of this study is to analyse the age-predicting performance of third molar index (I3M) in dental age estimation. A multiple regression analysis was developed with chronological age as the independent variable. In order to investigate the relationship between the I3M and chronological age, the standard deviation and relative error were examined. Digitalized orthopantomographs (OPTs) of 975 Italian healthy subjects (531 female and 444 male), aged between 9 and 22 years, were studied. Third molar development was determined according to Cameriere et al. (2008). Analysis of covariance (ANCOVA) was applied to study the interaction between I3M and the gender. The difference between age and third molar index (I3M) was tested with Pearsons correlation coefficient. The I3M, the age and the gender of the subjects were used as predictive variable for age estimation. The small F-value for the gender (F ¼ 0.042, p ¼ 0.837) reveals that this factor does not affect the growth of the third molar. ...

A simple and rapid method has been developed for the direct determination of the age (i.e. the prodution date) of uranium-containing nuclear materials by inductively coupled plasma mass spectrometry based on the measurement of the 230 Th/234 U radionuclide ratio. The concentration of the trace-level 230 Th in the samples was measured directly without the need of prior chemical separation. the tailing of the highly abundant 238 U peak, which is tipically around 10 orders of magnitude higher that that of the 230 Th signal, was eliminated by the matematical deconvolution of the measured mass spectrum. The 230 Th and 234 U contents were quantified by isotope dilution method. thje developed method was validated using reference materials of known production date ...

The coefficient values of correlation between the D/L ratio and actual age in adult lower central incisors were 0.996 (σ = ±1.0 year) for the total amino acid, 0.988 (σ = ±1.8 years) for insoluble collagen, and 0.997 (σ = ±0.9 years) for soluble peptide. The corresponding figures in adult first premolars were 0.991 (σ = ±1.6 years), 0.988 (σ = ±1.9 years), and 0.994 (σ = ±1.4 years), respectively. The reactive velocity of aspartic acid racemization was highest for soluble peptide in both the lower central incisors and first premolars and approximately three times as rapid as that for total amino acid. As a result, age estimated from the analysis of soluble peptide was most ...
Poor skeletal preservation is a ubiquitous problem in the Maya area, complicating the use of macroscopic techniques aimed at producing age range estimates. An important, but underutilized, set of skeletal approaches to aging employ microscopic methods, which rely on quantifying age-related histomorphological changes. This study focuses on histological structures in ribs and has two objectives: 1) to refine age estimations for burials from two rockshelters in the Caves Branch River Valley, Belize using regression formulas derived from contemporary Maya populations (Pavon et al. 2010); and 2) to explore the importance of sampling location in the application of these formulae. The method of Pavon et al. (2010) suggests using the midshaft of the fourth rib, but ancient Maya remains are often too fragmentary to confidently seriate and/or the midshaft may be absent. In an effort to determine whether the lack of locational consistency negatively affects this method, a modern anatomy sample of known age-at

Birth certificates and age assessments are available only to those resident in South Sudan. For children born in a hospital, the childrens parents can apply for a birth certificate within the first few days of the childs birth. If the child was born in a hospital and a birth certificate was not immediately obtained, then the child may be able obtain one, but would likely need an age assessment.. Children born outside of a hospital obtain an age assessment from each state health commission. The document contains the full name of the child, the parents names, the city and state where the child was born. A day/month/year is given at the time of the age assessment. The age is determined based on information gained at an interview with the child and parents, clan elders, dental exam, and circumference of the head, among other things.. All birth certificates and age assessments must be done in South Sudan. In the near future, each state will be able to process age assessments, which are only ...
My field and laboratory research is focused on paleobiological and biostratigraphic questions concerning the evolution of Mesozoic and Cenozoic terrestrial biotas. Currently I am studying the systematic interrelationships of Mesozoic mammals, making use of characters of both skeletal morphology and enamel microstructure. A stratigraphically controlled series of early Paleocene (Puercan) local faunas calibrated through 40Ar/39Ar age determinations provides the basis for analyses of the patterns and tempos of terrestrial faunal change during the first million years after the extinctions used to mark the end of the Cretaceous.. Graduate student research projects include: Investigation of the phylogenetic interrelationships, locomotor evolution, and turnover rates of Eocene artiodactyls; analysis of phylogenetic interrelationships and biogeographic distributions of Late Cretaceous and Early Cenozoic members of the Multituberculata; and study of the origins and evolutionary diversification of ...
Additional information:. total gas age - this row provides the mean age of all of the individual analyses (heating steps). Total gas ages and errors calculated by weighting individual steps by the fraction of 39Ar released. This age/error is analogous to a conventional K/Ar age determination. Other information in this row include the number of steps included in the weighted mean (n=10), the total moles of 39ArK contained within the sample and the mean K/Ca ratio for the sample. plateau - this row provides the mean age of those individual analyses specified by the geochronologist. Plateau weighted mean ages are calculated by weighting each age analysis by the inverse of the variance. Weighted mean error calculated using the method of (Taylor, 1982). Plateau must comprise at least two contiguous steps. Beyond this requirement, different 40Ar/39Ar laboratories have different criteria for defining plateau segments. Other information in this row include the MSWD (calculated for n-1 degrees of freedom ...
85% of Sr reacting with N2O and >70% Sr reacting with SF6; Rb does not react with either gas. As a result, the sensitivity for Sr reaction products is ∼10 times higher with N2O and ∼8 times higher with SF6 compared to O2. With these more reactive gases, the error of mica isochron ages, calibrated against a newly developed nano-particulate pressed powder tablet of mica-Mg, is ∼1% using a 50 μm laser spot. Our tests show that both N2O and SF6 form interfering reaction products, e.g., SrOH (N2O), SiF3 and TiF3 (SF6) that are difficult to handle using single mass spectrometer instruments, but which can be overcome using MS/MS. Using SF6 combined with H2, it is possible to measure 40Ca+ as 40Ca19F+, free from interference of 40Ar+ and 40K+. This facilitates the dating of micas by the K-Ca isotopic system; we present the first in situ K-Ca age determination. ...
By request from Bane NORs maintenance department, registration of vegetation was done on selected stations along four railway lanes during the summer of 2016. These four lanes were chosen because they are situated in different climate zones and have stations with plantings of varying size and complexity. The registrations included species identification, vegetation dimensioning, age determination, ground location and ground cover materials, weed growth, bush coverage, pests and damage, vitality, and need for maintenance measures. On the 23 stations, a total of 295 trees and area of 2491 m2 covered by shrub were registered. Of the 295 trees there were 31 tree species, 29 species and 2 cultivars. Of the 2491 m2 of shrub field there were 40 shrubs, 26 species and 14 cultivars. The use of vegetation was relatively little varied, and two birch species accounted for almost 30% of all tree species. There was greater variation in the use of bushes, but the largest variation was distributed on a few of ...

When electrons are released from traps the intensity of emitted luminescence follows linearly the amount of released electrons and can be used to find out the total amount of trapped electrons. From the amount of trapped electrons we can find out the total dose of radioactive radiation that has affected the crystals. This total dose can be used to the age determination when we measure the dose rate of radiation that has given that dose. Age (the time from the latest emptying of traps) can be found out by dividing the total dose with dose rate.. In dating the TL-method can be used to determine the age from samples that have been heated during their manufacturing process or when used (for example stones from fireplaces, bricks and ceramics). OSL-method can be used for example when dating sand formations. In both methods the main idea is that the traps are emptied at the specific time we are searching for. The traps in bricks and ceramic items are emptied during their manufacturing while they are ...

ABSTRACT: Many methods of age determination have been used to date. However, most of them require laboratory procedures which are, in general, not available for wildlife managers in the field. In this paper we attempt to standardize the age categories for six mammal species through the analysis of dental wear, dental eruption and body mass. We analyzed 632 skulls, including Mazama nemorivaga (brown brocket deer), Mazama americana (red brocket deer), Tayassu pecari (white-lipped peccary), Pecari tajacu (collared peccary), Cuniculus paca (paca) and Dasyprocta leporina (agouti). Using biological and morphological criteria we define four age categories: young, sub adult, adult and senescent adult. Scores and variables of molar cusp wear and eruption were defined for each age category within each species. We found significant differences in mean weights among age categories for D. leporina (F = 81.1; df = 3; p < 0.05), C. paca (F = 39.0; df = 3; p < 0.05), P. tajacu (F = 24.6; df = 3; p < 0.05) and ...

The age determination was based on counting the alternating light and dark bands present in the vertebrae, which calcify with age. Such bands have been shown to represent seasonal changes in modern sharks; this was tested in the fossil by examining difference in the isotopic composition of the dark and light bands, which reflects seasonal temperature changes. A modern great white shark of similar age likely would have been larger, suggesting that this fossil species grew at a slower rate. ...
M orphological changes of the articular surfaces of the innominate provides an excellent postcranial age indicators for adult remains. Variation in the face of the pubic symphysis, the anterior-most point of articulation between the two innominates in the pelvic girdle, is a common region analyzed for age determination. Todd (1920) outlined a 10-stage method for assessing this surface, based on a large sample of male innominates. Changes in the symphyseal surface over time proceed in a predictable pattern from a heavily contoured face, to one delimited by a rim in the mid 30s, to a surface marked by increasing porosity after 40 years. Analysis by Meindl and coworkers (1985) has shown the Todd method to be the most accurate of the pubic symphyseal methods available. It should be noted however, that a tendency to over-age individuals has been found after age 40 by some (BROOKS, 1955), while others claim under-aging of the 45+ year old individuals is problematic (Aiello and Molleson, 1993 ...

The age structure of populations is an important and often unresolved factor in ecology and wildlife management. Parameters like onset of reproduction and senescence, reproductive success and survival rate are tightly correlated with age. Unfortunately, age information of wild animals is not easy to obtain, especially for birds, where few anatomical markers of age exist. Longitudinal age data from birds banded as chicks are rare, particularly in long lived species. Age estimation in such species would be extremely useful as their long life span typically indicates slow population growth and potentially the need for protection and conservation. Telomere length change has been suggested as a universal marker for ageing vertebrates and potentially other animals. This method, termed molecular ageing, is based on a shortening of telomeres with each cell division. In birds, the telomere length of erythrocytes has been reported to decline with age, as the founder cells (haematopoietic stem cells) ...

Golf And Age:. The vast majority of golfers experience a significant loss in club head speed and distance as they age. Its a complaint I have heard from pretty much every golfer I have trained who is into their 50s, and certainly 60s. Golf score, and either directly or indirectly, level of enjoyment from the game starts to decline as this speed reduction occurs. Lets make one point very clear. Its not your chronological age that is primarily responsible for the decline in distance, it is your drop in strength and speed/power. There is a huge difference, because chronological age cannot be changed, but strength, power and speed levels most certainly can….at any age.. Why Does Speed Drop Off With Age?. By understanding the mechanisms that underlie this drop off in power it becomes much easier to try and apply appropriate training interventions.. 1 Decrease In Muscle Activity / Neural Drive:.

Age estimation from tooth - coronal index (TCI) using dental radiographs based on reduction in the size of the dental pulp cavity with advancing age as a result of secondary dentin deposition, has been presented.
This study was carried out in the eastern Transvaal Lowveld in an area 2 with a giraffe population density of 2,6 per km . Lions are the only predators and it was estimated that 48% of the calves die in their first year. The sex ratio departs significantly from unity in favour of females. Plant fragments in the rumen were identified. Giraffe subsist on the leaves of trees and shrubs, though fruit, flowers, twigs and grass were also utilised. Marked seasonal changes in the plant species selected were determined by availability and different habitats were utilised accordingly. Chemical analysis of rumen content showed correlations of nutritional value with species eaten and seasonal phenological changes of the vegetation. Tooth eruption, wear and incremental layers in the cementum were found to be suitable criteria for age determination. Total body mass was measured and carcasses dressed out at 61,9% for males and 56,6% for females. Lower mass and lower proportion of fat was found in the dry ...
Fetal intra-uterine growth charts are generally based on last menstrual period (LMP) data. Such charts may not really be applicable to infants whose gestational age is ultrasonically determined in early pregnancy. 1369 consecutive singleton pregnancies were studied. All fetuses had their gestational age estimated both by ultrasonic measurement of fetal crown-rump length and from registered last menstrual period data. All infants were weighed at birth as a part of the routine care. The age determination according to the two methods differed in 664 out of 1369 cases and in 516 of these 664 cases the age according to LMP was higher than according to CRL - a highly significant difference (p , 0.001). Mean values for birth weight were found to be larger when correlated to age in terms of CRL determinations than when related to age as calculated from LMP data. Birth weight also showed a significant increase between 40 and 42 weeks when age was determined ultrasonically. This was not the case when age ...

The postnatal gestational age estimation model previously published by our group included 249 700 infants born between April 2007 and March 2009. The details of the original model have been described previously.9 Briefly, infants who were identified as positive for any disorder screened for by NSO were excluded, as were infants with unsatisfactory samples, and missing gestational age and birth weight. Because complete metabolite profiles were required to score new observations, infants with missing analyte data or other covariates including gestational age, were excluded from this validation exercise. The infants excluded due to missing covariates constituted ,5% of the cohort. Gestational age was based on best obstetrical estimate (last menstrual period, dating ultrasound or a combination). It is to be noted that ,99% of women in Ontario receive at least one ultrasound during the course of pregnancy.10 The data were randomly partitioned into model development (50%), validation (25%) and test ...
Ankylosing spondylitis (AS) is a type of arthritis that affects the spine. Ankylosing means stiff or rigid, spondyl means spine, and itis refers to inflammation. The disease causes inflammation of the spine and large joints, resulting in stiffness and pain. The disease may result in erosion at the joint between the spine and the hip bone (the sacroiliac joint), and the formation of bony bridges between vertebrae in the spine, fusing those bones. In addition, bones in the chest may fuse. The cause of AS is unknown, although researchers suspect genetics play a role. A gene called HLA-B27 occurs in over 95 percent of those with AS. However, some people with the HLA-B27 gene do not have AS.. ...

Since 2002, approximately 15,000 migrants have landed by boat on the tiny European island nation of Malta, arriving in the country without permission, or "irregularly." Human Rights Watchs report documents how Malta has detained virtually all of these migrants without regard to age. Asylum seekers who arrive by boat are detained for up to 12 months, and migrants who do not apply for asylum (or who are rejected) can be detained for up to 18 months. Even the most vulnerable migrants - such as families with children, elderly people, and people with mental or physical disabilities - are taken to detention.. The report documents Maltas routine detention of unaccompanied migrant children - who are often fleeing violence or conflict in countries such as Somalia and Eritrea - pending the outcome of a lengthy age determination procedure. Unaccompanied migrant children are children traveling without parents or other guardians; typically they travel in dangerous conditions for many months before reaching ...

This study presents unique longitudinal data on skeletal maturation in adolescents from a middle-income country. Moreover, the study provides mean growth curves for RUS bone scores which permit the analysis of sex and ethnic differences in patterns of skeletal maturation. The results show that black boys mature later than white boys whereas black as well as white girls mature at the same age. A longitudinal analysis clarifies how this pattern emerges; skeletal maturation in black girls starts to accelerate later than in white girls, but develops faster, whereas in black boys, skeletal maturation starts to accelerate later and then develops at a similar rate.. The differing patterns of skeletal maturity in the two ethnic groups by sex are intriguing. In all populations, girls are more skeletally mature than boys from birth onwards and reach adult bone maturity, on average, 2 years earlier than boys (1.9 years here).2 Similarly, lower socioeconomic status is generally associated with delayed bone ...

WK59222 Standard Test Methods for Determining the Biobased Content of Solid, Liquid, and Gaseous Samples Using Radiocarbon Analysis
Finally, although contamination can sometimes occur, it should not be assumed in a particular instance unless there are good reasons to believe that it has. And a radiocarbon result that contradicts old-earth dogma is not a good enough reason by itself to invoke contamination!. Assumptions…Assumptions. Instead of arbitrarily blaming these anomalous results on contamination, a far better (and more scientific) approach would be to question the correctness of the assumptions behind radioisotope dating methods.. One of these assumptions is that nuclear decay rates have always been constant. Although 14C decays fairly quickly, heavier isotopes (such as uranium-238) decay much more slowly. Because the present decay rates of these heavier isotopes are so small, the assumption that these rates have always been constant naturally leads to age estimates of millions and even billions of years.. Interestingly, however, some radioisotope methods tend to consistently yield younger age estimates than others, ...
The media pulsates with ads laced with anti-aging products, all making youthful claims and promises. In todays society, there is a constant hum of cultural pressure aimed at looking younger and feeling better despite our chronological age. Does this place a moratorium on aging gracefully?

We develop a model of endogenous maturity structure for financial institutions that borrow from multiple creditors. We show that a maturity rat race can occur: an individual creditor can have an incentive to shorten the maturity of his own loan to the institution, allowing him to adjust his financing terms or pull out before other creditors can. This, in turn, causes all other lenders to shorten their maturity as well, leading to excessively short-term financing. This rat race occurs when interim information is mostly about the probability of default rather than the recovery in default, and is most pronounced during volatile periods and crises. Overall, firms are exposed to unnecessary rollover risk. ...

Estimation of age-at-death for skeletonised forensic remains is one of the most significant problems in forensic anthropology. The majority of existing morphological and histological techniques are highly inaccurate, and show a bias towards underestimating the age of older individuals. One technique which has been successful in forensic age estimation is amino acid racemization in dentine. However, this method cannot be used on remains where the post-mortem interval is greater than 20 years. An alternative approach is to measure amino acid racemization in dental enamel, which is believed to be more resistant to change post-mortem. The extent of amino acid racemization in the acid soluble fraction of the enamel proteins was determined for modem known age teeth. A strong correlation was observed between the age of the tooth and the extent of racemization. No systematic bias in the direction of age estimation errors was detected. For the majority of teeth analyzed, the presence of dental caries did ...
DNA methylation is a stable epigenetic modification which displays significant promise in forensic applications. The aim of this research was to assess the performance of DNA methylation markers in two of these: the differentiation of identical twins and the chronological age estimation of a biological sample donor. Candidate CpG sites were identified from the literature for each application and analysed using targeted multiplex amplification of bisulfite converted DNA in combination with massive parallel sequencing. Thirty-one CpG sites from three amplicons were examined in buccal samples collected from five pairs of identical twins. The results of this study confirmed that identical twins can be differentiated at the Alu-Sp and IGF2-shore loci, with all twin pairs displaying significantly different methylation patterns at Alu-Sp. A total of 84 CpG markers from seven loci were investigated in 28 blood samples collected from males and females aged from 22-62 years for the age estimation study. ...

I studied for my undergraduate degree at this very Department and it was during this time that I first developed an interest in studying human bones. On completing my degree, I spent a year working for various archaeological units; excavating sites of all periods and types from settlements to cemeteries. This work gave me the opportunity to excavate and analyse human skeletal remains from a variety of time periods. Having enjoyed this experience immensely, I undertook the MSc in Osteology, Palaeopathology and Funerary Archaeology taught jointly between the Universities of Sheffield and Bradford. It was during this time that I began to specialise in skeletal age estimation techniques and age as an aspect of social identity, and I returned to Durham University to pursue this subject at doctoral level. During the course of my PhD I became interested in the divide between science and social theory in archaeology and the implications of this for human skeletal analysis and funerary archaeology. This ...
Forensic Odontology In cases of mass disasters, fires, murders and many other scenarios the use of forensic Odontology is the key to identification.
Knowledge of gestational age at the time of birth is important for distinguishing the preterm from the small-for-gestational age (SGA) infant, whose medical needs and expectations for achieving significant development milestones may be different. Reliable gestational age estimates are also useful for quantifying population burdens of preterm birth, which can facilitate appropriate allocation of resources to hospital centres and regions of greatest need. In many low-income and middle-income countries, maternal access to prenatal care, in particular to ultrasound dating services, is limited and imprecise measures, such as last menstrual period, fundal height, or examination of the newborn are relied on for gestational age estimation.1-3 Given that gestational dating based on knowledge of last menstrual period is frequently unreliable4-6 and postnatal physical examinations are subject to variability based on subjective scoring and poor performance in extreme preterm and SGA infants,7 8 new methods ...
Background: Both the Tanner-Whitehouse-III RUS score, which is based on the radiographic appearance of the epiphyses of the distal part of the radius, the distal part of the ulna, and small bones of the hand, and the digital skeletal age skeletal maturity scoring system, which is based on just the metacarpals and phalanges, correlate highly with the curve acceleration phase in girls with idiopathic scoliosis. However, these systems require an atlas and access to the scoring system, making their use impractical in a busy clinical setting. We sought to develop a simplified system that would correlate highly with scoliosis behavior but that would also be rapid and reliable for clinical practice. Methods: A simplified staging system involving the use of the Tanner-Whitehouse-III descriptors was developed. It was tested for intraobserver and interobserver reliability by six individuals on thirty skeletal age radiographs. The system was compared with the timing of the curve acceleration phase in a ...

Abscess -A localized collection of pus in the skin or other body tissue caused by infection. Bicuspid -Premolar; the two-cupped tooth between the first molar and the cuspid. Calcification -A process in which tissue becomes hardened due to calcium deposits. Calculus -Plural, calculi. Any type of hard concretion (stone) in the body, but usually found in the gallbladder, pancreas, and kidneys. They are formed by the accumulation of excess mineral salts and other organic material such as blood or mucus. Calculi (pl.) can cause problems by lodging in and obstructing the proper flow of fluids, such as bile to the intestines or urine to the bladder. In dentistry, calculus refers to a hardened yellow or brown mineral deposit from unremoved plaque, also called tartar. Canines -The two sharp teeth located next to the front incisor teeth in mammals that are used to grip and tear. Also called cuspids. Crown -The natural part of the tooth covered by enamel. A restorative crown is a protective shell that fits ...
Amplified climate warming in the Arctic may cause thaw-remobilization of its large soil organic carbon (SOC) pool. Here we assess the remobilization and preservation of old SOC by the watershed-integrated radiocarbon signature of molecular SOC markers released from northernmost Scandinavia. The radiocarbon analyses revealed a remarkable fractionation for identical vascular plant markers (~420ppm or ~6000 14C years) upon settling from surface water to the underlying sediments. From this, we infer fluvial export of two SOC pools; a young surface peat component, and an old deep mineral soil component. The young pool exists as an easily degradable humic suspension, while the old pool is matrix protected from degradation and ballasted for preferential settling. The two soil types with highest OC in Arctic permafrost evidently exhibit different susceptibilities to degradation. Hence, a significant part of the thaw- released OC may simply be fluvially relocated to sediments instead of being emitted to ...
Bone age assessment, a crucial part of the diagnosis and management of pediatric growth disorders as well as the timing of certain pediatric orthopedic procedures, has for decades depended on the meticulous examination of plain radiographs.
Bottom line: if you are one of those who equates "starting" with "riding", then I guess you better not start your horse until hes four. That would be the old, traditional, worldwide view: introduce the horse to equipment (all kinds of equipment and situations) when hes two, crawl on and off of him at three, saddle him to begin riding him and teaching him to guide at four, start teaching him maneuvers or the basics of whatever job hes going to do - cavalletti or stops or something beyond trailing cattle - at five, and hes on the payroll at six. The old Spanish way of bitting reflected this also, because the horses teeth arent mature (the tushes havent come in, nor all of the permanent cheek teeth either) until hes six.= This is what Id do if it were my own horse. Im at liberty to do that because Im not on anybody elses schedule except my horses own schedule. Im not a participant in futurities or planning to be. Are you? If you are, well, thats your business. But most horse owners ...
Doctors have long observed that biological age and chronological age are not always one and the same. A 55-year-old may exhibit many signs of old age and have numerous age-related diseases, whereas an 80-year-old may be healthy and robust.
Forensic dentistry or Forensic Odontology represents the overlap between the dental and the legal professions. It is the application of dental science in the legal sphere. It is the examination and evaluation of dental evidence which will then be presented in the interest of justice. The profession of forensic odontology can make a significant contribution to the field of forensic science in the identification of people both dead and living. It incorporates dental anatomy, histology, radiography, dental materials and developmental anomalies of definition. The scope of forensic odontology includes identification of victims of accidents, incineration in vehicles, house fires. ...
Natural abundance radiocarbon analysis facilitates distinct source apportionment between contemporary biomass/biofuel (14C "alive") versus fossil fuel (14C "dead") combustion. Here, the first compound-specific radiocarbon analysis (CSRA) of atmospheric polycyclic aromatic hydrocarbons (PAHs) was demonstrated for a set of samples collected in Lycksele, Sweden a small town with frequent episodes of severe atmospheric pollution in the winter. Renewed interest in using residential wood combustion (RWC) means that this type of seasonal pollution is of increasing concern in many areas. Five individual/paired PAH isolates from three pooled fortnight-long filter collections were analyzed by CSRA: phenanthrene, fluoranthene, pyrene, benzo[b+k]fluoranthene and indeno[cd]pyrene plus benzo[ghi]perylene; phenanthrene was the only compound also analyzed in the gas phase. The measured Delta 14C for PAHs spanned from -138.3 per mil to 58.0 per mil. A simple isotopic mass balance model was applied to estimate ...

When Entertainment Tonight host Nancy ODell set out to teach her young daughter Ashby how to brush her teeth, she knew the surest path to success would be to make it fun for the toddler.. "The best thing with kids is you have to make everything a game," Nancy recently said in an interview with Dear Doctor TV. She bought Ashby a timer in the shape of a tooth that ticks for two minutes - the recommended amount of time that should be spent on brushing - and the little girl loved it. "She thought that was super fun, that she would turn the timer on and she would brush her teeth for that long," Nancy said.. Ashby was also treated to a shopping trip for oral-hygiene supplies with Mom. "She got to go with me and choose the toothpaste that she wanted," Nancy recalled. "They had some SpongeBob toothpaste that she really liked, so we made it into a fun activity.". Seems like this savvy mom is on to something! Just because good oral hygiene is a must for your childs health and dental development, that ...
MONDAY, May 22, 2017 (HealthDay News) -- Limiting calorie intake may slow aging, a new study suggests.. Previous research has shown that calorie restrictions slow aging in worms, flies and mice, so Duke University researchers wanted to see if it could slow biological aging in people.. "Biological aging is the gradual and progressive deterioration of systems in the body that occurs with advancing chronological age," said study author Daniel Belsky, an assistant professor of medicine at Duke, in Durham, N.C.. "If we can intervene to slow the rate of biological aging, it may be possible to prevent or at least delay onset for many age-related diseases and disabilities," he explained in a university news release.. The researchers looked at 145 people who achieved a 12 percent reduction in calorie intake over two years and a control group of 75 people who did not restrict calories. At the start of the study, the average biological age of participants in both groups was 37, and their chronological age ...
Hi Richard!Jamie C. put this on Supertraining today. I figured youd be ineestrted:Tweaking a gene makes muscles twice as strongA team of researchers at EPFL, the University of Lausanne and the Salk Institute created super strong, marathon mice and nematodes by reducing the function of a natural inhibitor, suggesting treatments for age-related or genetically caused muscle degeneration are within reach.It turns out that a tiny inhibitor may be responsible for how strong and powerful our muscles can be. This is the surprising conclusion reached by scientists in EPFLs Laboratory of Integrative Systems Physiology (LISP), in collaboration with a group in the Center for Integrative Genomics at the University of Lausanne and at the Salk Institute in California. By acting on a receptor (NCoR1), they were able to modulate the transcription of certain genes, creating a strain of mighty mice whose muscles were twice a strong as those of normal mice. Two protein-building regulators The process of ...
The assembly of a 1.3-Mb size region of the wheat genome has provided the opportunity to study a recent nuclear mitochondrial DNA insertion (NUMT). In the present study, we have studied two bacterial artificial chromosomes (BACs) and characterized a 52-kb NUMT segment from the tetraploid and hexaploid wheat BAC libraries. The conserved orthologous NUMT regions from tetraploid and hexaploid wheat Langdon and Chinese Spring shared identical gene haplotypes even though mutations (insertions, deletions, and substitutions) had occurred. The 52-kb NUMT was present in hexaploid variety Chinese Spring, but absent in variety Hope, by sequence comparison of their corresponding region. Amplifying the NUMT junctions using a set of the wheat materials including diploid, tetraploid, and hexaploid lines showed that none of the diploid wheat carried the region and only some tetraploid and hexaploid wheat were positive for the NUMT. Age estimation of the NUMT displayed the mean ages of Langdon NUMT and Chinese ...

In the study, 44 teeth from 41 individuals were analyzed using racemization (a chemical process in which one amino acid is converted to its counterpart) analysis of tooth crown dentin or radiocarbon analysis of enamel, and 10 of these were split and subjected to both radiocarbon and racemization analysis. Combined analysis showed that the two methods correlated well.. Carbon-14, or radiocarbon, is naturally produced by cosmic ray interactions with air and is present at low levels in the atmosphere and food. Although nuclear weapons testing was conducted at only a few locations, excess levels of 14C in the atmosphere rapidly dispersed and equalized around the globe.. Since 1963, as a result of a worldwide test ban treaty, 14C levels in the atmosphere have been decreasing exponentially with a mean half-life of 16 years. Carbon-14 levels have not decreased because of radioactive decay (14C has a half-life of 5,730 years), but rather 14C has moved out of the atmosphere due to mixing with large ...
Previously, researchers haveidentified a key protein, called p16INK4a, that increase in mammalian organs as as cells and tissues age. Recently, they have found out that the protein is also present in human blood and is strongly correlated both with chronological age and with certain behaviors such as tobacco use and physical inactivity, which are known to accelerate the aging process. Based on these findings, they have developed a simple blood test to detect p16p16INK4a expression, which is present in cells called T-lymphocytes, also known as T-cells.. They found that expression of the biomarker was strongly correlated with the donors chronological age and, in fact, increased exponentially with age. In addition, increased levels were independently associated with tobacco use and physical inactivity as well as with biomarkers of human frailty.. Sharpless said that the researchers were surprised by some of their findings, "We found a very weak correlation between the biomarker and obesity - as ...
In terms of wanting to be "with Him"....Amen to that! And, while Im not all -that- old, Im older than my chronological age due to the stresses of when the divorce happened. I think I aged 5-6 years that first year. way back when it happened, I was so stressed out I thought maybe I would die of a heart attack/failure.....but then the Lord gave me assurance that I would see the Rapture. But these days I am -feeling- a lot older than I was. I was having a conversation with a neighbor (at work) the other day about this very thing. Actually, Ive had conversations with two different people. The one fellow figures that 1) you live, and then 2) you die. Period. Dont keep him hooked up to machines....when its time, just let him die. The other was a proponent of Jack Kevorkian (sp?)....such that, when a person is getting near the end of their life, what better (more loving) thing than to help them take control of their end-of-life experience....do it calmly, painlessly, etc. Just take a pill ...
MAYET, Z; LUKHELE, M and MOHAMMED, N. Risser sign: trends in a South African population. SA orthop. j. [online]. 2010, vol.9, n.4, pp.20-25. ISSN 2309-8309.. INTRODUCTION: In scoliosis management the five stages of the Risser sign on the iliac crest have been widely used as a tool to assess skeletal age and remaining spinal growth. However, as with other markers of skeletal age, it is under the influence of genetic and environmental factors. Proof of this was given by Risser, who observed that children in warmer climates developed earlier. Numerous other authors have also shown differences for other measures of maturity between different race groups. OBJECTIVE: This study was aimed at determining the trends of Iliac crest apophyseal ossification as represented by the Risser sign in the South African population and how it compares with that published by Scoles et al in their population group. METHOD: Radiographs of patients between the ages of 8 to 20 years undergoing abdominal X-rays for ...
Aim: To analyze the height gain in children with precocious puberty who have been treated with GnRH-A for at least three years. Method and Materials: 18 patients (16 girls and 2 boys) with isosexual complete precocious puberty were included in the current study. Diagnosis was documented by LHRH stimulation test plus sex steroid assays. The mean age at onset of treatment was 6 years (SD = 2.41) and skeletal maturation was advanced (mean = 8.67, SD = 2.77 years). Hormonal profiles and skeletal maturation were monitored throughout the treatment course. Results: The mean height SDS for age during the first 3 years of treatment followed the prepubertal reference values, but the height SDS based on skeletal maturation at the onset of treatment improved by 0.9 SDS during the three years of treatment (p,0.01). In a multiple regression analysis, height SDS and the advancement of skeletal maturation at the onset of treatment explained 41% of the growth response in the first 3 years. Neither the age at ...
