Egyptians are one of the first civilisations to practice the removal and examination of internal organs of humans. Their practices ranged from embalming to faith healing to surgery and autopsy. Modern radiological studies, together with various forensic techniques, allowed scientists unique glimpses of the state of health in Egypt 4000 years ago and discovered one of the earliest applications of autopsy, the main element of forensic medicine practice today. The Egyptian Forensic Medicine Authority handles a relatively large number of cases annually and depends on different assisting laboratories (forensic histopathology, microbiology, serology unit, DNA laboratory, forensic chemistry laboratory) as well as the Counterfeiting and Forgery unit. Crime scene investigations are performed mainly through the criminal laboratory related to the Ministry of Interior. Forensic Medicine is studied thoroughly in the faculty of medicine (undergraduates), as well as by forensic medical examiners at postgraduate level (diploma, master's and doctorate). This review recommends more scientific cooperation with universities in the field of forensic medicine and related sciences to solve various crimes with meticulous detail. © 2010 Elsevier Ltd and Faculty of Forensic and Legal Medicine.

Background: Sex crimes are complex and multidimensional; over the past few decades, child sexual abuse has gained public attention and become one of the most high-profile crimes. Since the 1970s, sexual abuse of children and child molestation has increasingly been recognized as deeply damaging to children and unacceptable for society as a whole. Methods: This is a retrospective and prospective study evaluating sexual assault against children in the Suez Canal area in Egypt from 2004 to 2009, assessing the prevalence of sexual assault and associated factors among its victims. Examination was carried out in the Medico-Legal department of Ministry of Justice, Suez Canal area including Ismailia, Port-Said, El-Suez, and North Sinai cities. Results: There were 128 cases in the age range of 5-18. years (53.9% girls and 46.1% boys). Of these cases, 88.3% were between 10 and 18. years old, and 11.7% were between 5 and 10. years old. Those living in urban areas comprised 83.6% of the cases, and 16.4% lived in rural areas. Intra-familial assailants comprised 13.3% of the cases, while 86.7% were extra-familial to the victims. From the intra-familial cases, 35.3% of the cases were incest against girls and 29.4% cases were intra-familial sodomy against boys. In 63.1% of the cases, the assailants were unknown to the victim; 18.7% reported sexual assault by more than one attacker, and 7.1% of cases reported sexual assault combined with physical assault. The most frequently reported types of abuse were anal assault (52.3%) followed by incomplete vaginal penetration (36%) and complete vaginal penetration (7.8%). Mixed assaults - vaginal and anal - occurred in 3.9% of the cases. Sexual assault was made under verbal threat in 39% of the cases, while sexual assault was made under armed threats in 3.9% of cases. In 34.4%, examination of the victims was done within 3. weeks of the assault in 26.6% of cases, examination was done within 2. weeks; in 14.8%, examination of the child was done after 1. month, and in 10.2% of cases, examination was done within 2-4. days of the crime. Conclusions: Doctors and other health professionals should be aware of the high prevalence rate of child abuse and its potential for initial and long-term deleterious outcomes. © 2011.

Novel chitosan-ZnO composites have been synthesized as luminescent taggants for cellulosic materials. The synthesized chitosan-ZnO nanospheres (CS-ZnO NS), chitosan-ZnO-oleic acid quantum dots (CS-ZnO-oleic QD) and chitosan-ZnO-oleic acid:Eu3+ doped nanorods (CS-ZnO-oleic:Eu3+ NR) were characterized by X-ray diffraction, photoluminescence spectroscopy, FTIR spectroscopy and transmission electron microscopy. The prepared luminescent CS-ZnO composites were used in printing paste and applied to different types of papers and textiles by using screen printing technique. The colorimetric values of the printed CS-ZnO-oleic acid and CS-ZnO-oleic:Eu3+ showed that printing caused slightly change in color values. Scanning electron microscopy images and color values of the printed surface showed that CS-ZnO-oleic QD and highly luminescence CS-ZnO-olic:Eu3+ NR are suitable for use as a printed security feature. © 2013 Elsevier Ltd.

The electrochemical behavior of copper(II)-omeprazole complex was studied by differential pulse and cyclic voltammetry at a hanging mercury drop electrode. A well-defined voltammetric peak was obtained at −0.6 V (vs. Ag/AgCl sat’d KCl) in phosphate buffer (pH 7). The experimental results show that the reduction of the copper(II)-omeprazole complex is irreversible. The stoichiometry and stability constant of the Cu(II)-omeprazole complex were evaluated using differential pulse cathodic adsorptive stripping voltammetry and found to be 1 : 2 and 1.39 × 1011 M−1. The limits of detection and quantitation were found to be 3 × 10−9 and 1 × 10−8 M, respectively. The proposed procedure was successfully applied for the determination of trace level of copper in bottled natural drinking water samples. © 2015, Pleiades Publishing, Ltd. Source

Disappearing inks have been used in different fields, but it may be abused in forgery and counterfeiting. This research was conducted on the preparation of disappearing inks using different concentrations of thymolphthalein, phenolphthalein, and their mixture. The prepared inks were applied to different types of handwriting papers. It was found that the handwriting stability increased by increasing thymolphthalein, phenolphthalein, or alkali concentration, but in the case of using 4mL of 1 normal (N) NaOH, the handwriting stability of phenolphthalein and its mixture inks decreased. Deciphering of the faded handwriting was evaluated by different methods; using optical deciphering, the faded handwriting did not respond to the different light sources. All the faded handwriting was visible when treated with alkaline solution. There was no change in the faded handwriting when heated to 100°C; phenolphthalein and mixture inks containing 0.5mL of 1N NaOH became red when only Azhar and Xerox papers were heated to 150°C. © 2012 American Academy of Forensic Sciences.
