Abstract

Sidik bibir merupakan suatu pola berupa fissure pada permukaan mukosa bibir yang bersifat unik, stabil. Dimorfisme seksual sidik bibir ditemukan pada beberapa populasi di dunia seperti populasi di India dan Thailand. Secara fenotif, populasi Indonesia terutama populasi Indonesia Barat berbeda dengan populasi lain di dunia, sehingga tidak menutup kemungkinan terdapat dimorfisme seksual sidik bibir. Tujuan dari penelitian ini untuk mengetahui pola dan dimorfisme seksual sidik bibir pada populasi Indonesia Barat. Sampel penelitian ini total berjumlah 477 orang, yang terbagi atas 265 laki-laki dan 212 perempuan. Metode pemeriksaan yang digunakan adalah metode Suzuki dan Tsucihasi, dengan membagi bibir menjadi 8 kuadran. Hasil penelitian menunjukkan laki-laki dan perempuan pada populasi Indonesia Barat memiliki frekwensi tipe sidik bibir paling dominan type 1’, dan terdapat dimorfisme sidik bibir yang signifikan pada type 3 dan type 4 pada laki-laki dan type 1 pada perempuan. Sidik bibir merupakan salah satu metode identifikasi yang dapat dipakai untuk identifikasi ras dan jenis kelamin. Populasi Indonesia Barat memiliki pola sidik bibir dominan tipe 1’  yang berbeda dengan populasi lainnya di dunia.

Abstract

Deproteinated human bone with hydrazine indicated that percentage of bone mass mineral increased with individual age in the range of child to adult, and then slowly decreased with ageing. Type of bone and sex also influenced the proportional of mineral in bone. Several information was obtained from infrared spectroscopy measurements. Calcium phosphate in bone mineral was a mixture of amorphous calcium phosphates and apatite crystals that rich of carbonates. Most crystals were carbonate apatite type B, with additional small amount of type A and AB. The splitting factor of υ4 phosphate bands indicated that crystalline degree was regulated by age, increases in the range of child to adult, then decrease up to a certain value (0.16) and finally almost constant. It is predicted that apatite crystals that was formed with less calcium phosphate will accompanied by the insertion of crystallization water in order to maintain the constancy of bone volume.

Abstract

BACKGROUND Adipose tissue is often overlooked in DNA testing due to misconceptions about its DNA content. However, its shock-absorbing qualities may be useful for high-pressure scenarios like bomb blasts. This study aimed to evaluate DNA quality and quantity in adipose tissue affected by blasts compared to that in unaffected tissue. METHODS 10 adipose tissue samples were taken from regions near and far from the blast, representing the blast-exposed and non-blast-exposed groups. The adipose tissue was stored at a low temperature for 5 days, after which an organic extraction method was applied. The purity of the DNA extract was assessed using a NanoDrop spectrophotometer, and its integrity was evaluated using 0.8% concentration gel electrophoresis at 60 V for 90 min. DNA typing was conducted using the GlobalFiler™ kit, and DNA quantity was determined with the Quantifiler™ Trio DNA Quantification kit. RESULTS Of 20 DNA extracts from adipose tissue, all samples demonstrated purity, integrity, and complete typing results. Adequate integrity was found in 90% of samples in both groups. A 50% incidence of allele shifting was observed at the D7S820 locus within the blast-exposed group. CONCLUSIONS DNA from blast-exposed adipose tissue exhibited no significant quality or quantity differences from non-blast-exposed tissue. This suggested adipose tissue’s potential as an alternative DNA source in a bomb explosion.
