In this study, we investigated whether there were differences between parental obesity, children’s and parent’s awareness of body shape, and dietary habits according to obesity levels in children with precocious puberty. A total of 193 children (93.3% girls) diagnosed with precocious puberty were classified into three groups according to their obesity levels. Negative body shape awareness and dissatisfaction were significantly higher in the obese group than in the normal-weight group, and parents were more likely to perceive their children as fat than the children themselves. In addition, the obesity rate of parents in the obese group was higher, and the body mass indexes of children and parents were significantly correlated. -

Identification of Teeth, Wrist and Femur Bone Features for Age and Gender Identifiction
Vidyashree H S et al. / International Journal of Computer Science Engineering (IJCSE) IDENTIFICATION OF TEETH, WRIST AND FEMUR BONE FEATURES FOR AGE AND GENDER IDENTIFICTION Vidyashree H S Department of Computer Science and Engineering, Bapuji Institute of Engineering and Technology, Davanagere, India. Email: [email protected] Pradeep N Department of Computer Science and Engineering, Bapuji Institute of Engineering and Technology, Davanagere, India. Email: [email protected] Abstract: Personal identification is defined as establishing the identity of an individual. The need for personal identification arises in natural mass disasters like earth quakes, tsunamis, landslides, floods etc., and in man-made disasters such as terrorist attacks, bomb blasts, mass murders, and in cases when the body is highly decomposed or dismembered to deliberately conceal the identity of the individual. Computers have been widely used in the field of medical research over the past few decades. Machine Learning and Biomedical Image Processing Techniques have enormously contributed in the field of Medical Image Analysis, classification and recognition. But fewer contributions have been made in the area of forensics by researchers. There is a scope for researches, where they can make their contributions especially in medical image analysis where they can estimate age and identify gender using digital X-ray images. In this paper, we are identifying features of Femur, Teeth and Wrist features that are helpful for age and gender identification. Keywords- Forensic Science, Femur Bone Age, Gender Estimation, teeth, wrist bone age and gender comparison. I.INTRODUCTION The age of an individual is often a fundamental piece of data in connection with forensic identification of unidentified bodies. -
Development of the Endochondral Skeleton

Elucidating the mechanisms that control endochondral bone development is critical for understanding human skeletal diseases, injury response, and aging. Mouse genetic studies in the past 15 years have provided unprecedented insights about molecules regulating chondrocyte formation, chondrocyte maturation, and osteoblast differ- entiation, all key processes of endochondral bone development. These include the roles of the secreted proteins IHH, PTHrP, BMPs, WNTs, and FGFs, their receptors, and transcription factors such as SOX9, RUNX2, and OSX, in regulating chondrocyte and osteoblast biology. This review aims to integrate the known functions of extracellular signals and transcription factors that regulate development of the endochondral skeleton.

We presented the clinical and biochemical characterization in two patients (a 13 year-old girl (46, XX) with hypokalemia and lack of pubertal development, a 11 year-old girl (46, XY) with female external genitalia and severe hypertension). CYP17A1 mutations were detected by PCR and direct DNA sequencing in patients and their parents. A homozygous mutation c.985_987delTACinsAA (p.Y329KfsX418) in Exon 6 was found in patient 1, and a homozygous deletion mutation c.1459_1467delGACTCTTTC (p.Asp487_Phe489del) in exon 8 in patient 2. The patients manifested with hypertension, hypokalemia, sexual infantilism should be sus- pected of having 17a-hydroxylase/17,20-lyase deficiency. Definite diagnosis is depended on mutation analysis. Hydrocortisone treatment in time is crucial to prevent severe hypertension and hypokalemia.

Musculoskeletal Morphing from Human to Mouse

Biomechan- ical modeling and robotics computation have been integrated to extend the applications of musculoskeletal analysis of human movements. The analysis would also provide valuable means for the other mammalian animals. One of current approaches of post-genomic research focuses to find connections between the phenotype and the genotype. The former means the visible morphological or behavioral expression of an animal, while the latter implies its genetic expression. Knockout mice allows to study the developmental pathway from the genetic disorders to the behavioral disorders. Would musculoskeletal analysis of mice also offer scientific means for such study? This paper reports our recent technological development to build the musculoskeletal model of a laboratory mouse. We propose mapping the musculoskeletal model of human to a laboratory mouse based on the morphological similarity between the two mammals. Although the model will need fine adjustment based on the CT data or else, we can still use the mapped musculoskeletal model as an approximate model of the mouse’s musculoskeletal system. -

Homeobox Genes D11–D13 and A13 Control Mouse Autopod Cortical

The molecular mechanisms that govern bone and joint formation are complex, involving an integrated network of signaling pathways and gene regulators. We investigated the role of Hox genes, which are known to specify individual segments of the skeleton, in the formation of autopod limb bones (i.e., the hands and feet) using the mouse mutant synpolydactyly homolog (spdh), which encodes a polyalanine expansion in Hoxd13. We found that no cortical bone was formed in the autopod in spdh/spdh mice; instead, these bones underwent trabecular ossification after birth. Spdh/spdh metacarpals acquired an ovoid shape and developed ectopic joints, indicating a loss of long bone characteristics and thus a transformation of metacarpals into carpal bones. The perichon- drium of spdh/spdh mice showed abnormal morphology and decreased expression of Runt-related transcription factor 2 (Runx2), which was identified as a direct Hoxd13 transcriptional target. Hoxd11–/–Hoxd12–/–Hoxd13–/– tri- ple-knockout mice and Hoxd13–/–Hoxa13+/– mice exhibited similar but less severe defects, suggesting that these Hox genes have similar and complementary functions and that the spdh allele acts as a dominant negative. -

Because of the the ages at which the different epiphyses fuse with the respective existence of such racial, geographic and climatic diaphyses in long bones. These variations have suggested need of variations, need for separate standards of ossification for separate standard of ossification for separate regions. This leads us separate regions have been suggested (Loder et al 1993 14 ; to study ages of epiphyseal union around elbow joint, a rarely Koc et al. 2001 10 ; Crowder et al. 2005 6).
