    Full text link
    Animal hair examination at a criminal scene may provide valuable information in forensic investigations. However, local reference databases for animal hair identification are rare. In the present study, we provide differential histological analysis of hair of some domestic animals in Upper Egypt. For this purpose, guard hair of large ruminants (buffalo, camel and cow), small ruminants (sheep and goat), equine (horse and donkey) and canine (dog and cat) were collected and comparative analysis was performed by light microscopy. Based on the hair cuticle scale pattern, type and diameter of the medulla, and the pigmentation, characteristic differential features of each animal species were identified. The cuticle scale pattern was imbricate in all tested animals except in donkey, in which coronal scales were identified. The cuticle scale margin type, shape and the distance in between were characteristic for each animal species. The hair medulla was continuous in most of the tested animal species with the exception of sheep, in which fragmental medulla was detected. The diameter of the hair medulla and the margins differ according to the animal species. Hair shaft pigmentation were not detected in all tested animals with the exception of camel and buffalo, in which granules and streak-like pigmentation were detected. In conclusion, the present study provides a first-step towards preparation of a complete local reference database for animal hair identification that can be used in forensic investigations.Comment: 8 pages, 3 Figure

    The size of subarcuate fossa of six different mammals has been observed. Among the examined species; camel, dog, rabbit and rat show clear subarcuate structure, which was characterized by the shape of fossa, and could be easily measured by using endocast. In these species the parafloccular lobe of cerebellum is isolated from cranial cavity and engulfed by this fossa. However, in donkey, the fossa is unclear or absent. Studies have reported correlated relationship between the subarcuate fossa and the size of skull and certain parts of the cerebellum. The size of the subarcuate fossa is varying from absence of the fossa to large size fossa with its high contribution area of skull size. Dog has the largest subarcuate fossa among the examined species in this study followed by rabbit then camel, after that rat, very small in ruminants and nearly absent in equine. The study reveals the possibility of subarcuate fossa to determine the degree of evolution of the animals, based on variation of this fossa in closely related animals. This order does not follow any previous study in literatures that hypothesis correlation between the size of subarcuate fossa and the size of skull or animal size or even part of cerebellum which evolved in this fossa. The result of this paper supports the hypothesis of the correlation relationship between subarcuate fossa and phylogeny of the animals

    This study was carried out to evaluate the anesthetic, cardiorespiratory, and sedative effect of lidocaine, medetomidine and lidocaine-medetomidine used for intravenous regional analgesia (IVRA) in the hind limb of goats. The anatomical venous map of the pes region was evaluated. Twenty-one mature native female goats were allocated to this study. They were divided into two groups: The first group (n.= 6) was subjected to anatomical evaluation and the second group (n.= 15) was randomly divided into three equal subgroups, which were subjected to the technique of IVRA. The animals received lidocaine HCl (LID), medetomidine HCl (MED), and combination of the two drugs (LID-MED) in the 1st, 2nd, and 3rd subgroups respectively. The anesthetic score and cardiorespiratory values were recorded at the baseline (0), and at 5, 10, 20, 30 and 45 minutes post anesthetic injection and at 5, 10, 20 and 30 minutes after removal of the elastic tourniquet. The results revealed that the venous networking in the dorsal aspect of the pes composes of two metatarsal veins in four specimens and three veins in two specimens, which unite at the proximal third of the metatarsal to form a single vein. The onset of desensitization was 12.0±6.0 seconds in LID and LID-MED subgroups. The duration of sedation was 85.0±12.0 minutes (MED) and 91.0±10.0 minutes (LID-MED). The anesthetic score was significantly (P≤0.05) higher in LID and LID-MED subgroups. Marked bradycardia and increased respiratory rate were observed in MED and LID-MED subgroups. It could be concluded that the lidocaine-medetomidine combination that used for intravenous regional anesthesia in goats gives satisfactory results regarding to the sedative and anesthetic effects

    Numerous digital media and tools, and they are increasing diversity and growth and interference over time, and these means: Interactive television stations, digital cable, electronic press, hotspots, blogs, personal, corporate and commercial sites, social networking sites, video clips, digital radio stations, virtual community networks, mailing groups and more. Mobile phones that transmit digital radio, interactive television, websites, music, video clips, stock trading, weather, air traffic, digital maps, text message groups and multimedia. Introduction Lack of familiarity of the news television photographer with the different techniques of the concept of the mobile image that enables him to meet the requirements of the production of his work and the implementation of his visions and ideas, according to specific criteria. Lack of interest in the function and concept of television news in terms of (news function - informatics - the authentication and credibility of the event - the visual function - the psychological impact on the viewer). Objectives: Promoting and promoting news work represented in the news story in the information age and satellite channels. Set up professional controls and standards for news coverage in the theater that is binding on every photographer working in the field of news. Spread the culture of quality in the work of news media through the controls and standards of professional coverage of the news. So that the side of the esophagus corresponds to the linguistic side. Methodology This approach follows the description and analysis to reach the results. Results: The small size and low weight of the camera has become the biggest source of effort from the photographer during filming, and thus can guide this effort in skill and accuracy in performance and maneuverability, which is one of the most important elements of professional news coverage. The news photographer is always waiting - and quick-alert - and good news, not dazzling. The news photographer must have a vision before he depicts "visualization is the process of forming ideas and perceptions and revive the pulpit and visual stimuli in the mind of the individual are not before him at the time of the process of photography. Future Directions: It is recommended to study the completion of scientific research in the field of "mobile phone television" and the limits of research Is mobile phone canceled the role of mobile news cameras? Is mobile phone the place of portable broadcasters? Is the mobile phone rival to the professional news photographer? References: Visual Communication – Second Edition 2000, by words worth.

    Get PDF
    Background: Adolescent idiopathic scoliosis is an abnormal curvature of the spine that appears in late childhood or adolescence. Instead of growing straight, the spine develops a side-to-side curvature, usually in an elongated "S" or "C" shape; the bones of the spine are also slightly twisted or rotated. To prevent further curve progression and obtain a balanced spine, surgery remains the mainstay of treatment for idiopathic scoliosis (IS). Objective: This study aimed to discuss three dimensional surgical techniques used for correction of adolescent idiopathic scoliosis, evaluating their feasibility, efficacy and safety. Patients and methods: This study was conducted in Mansoura University Hospital and Alexandria University Hospitals between September 2018 and April 2021. 3D surgical correction was performed for 91 patients complaining of idiopathic scoliosis, and not responding to conservative measures and not associated with neurological affection. Results: According to Lenke classification, there were 56 patients (61.5%) with type 1 curve type , 9 patients (9.9%) with type 2, 7 patients (7.7%) with type 3, 7 patients (7.7%) with type 5 and 12 patients (13.2%) with type 6. Mean preoperative height was 1.60 m while mean postoperative height was 1.66 m. with significant increase in height postoperatively (p < 0.001). Mean percentage height gain was 3.91%. Conclusion: We do believe that the posterior only approach 3D correction is an effective method in management of AIS concerning correction of Cobb angle, shoulder balance and spinopelvic parameters and recommend it as the best way nowadays to treat this disease

    Background: Blunt force abdominal trauma is a typical emergency room presentation in both adults and children. Trauma is widely acknowledged as one of the primary causes of illness and mortality in poor nations, as well as the greatest cause of death in those under the age of 45.Objectives: This study aims to study the diagnostic evaluation of blunt abdominal trauma scoring system (BATSS) in patients with blunt abdominal trauma in Zagazig University Hospital.Patients and methods: This study was conducted on 48 patients suffering from blunt abdominal trauma in Emergency Department of Zagazig University Hospital from January 2021 to June 2021.Result: The mean age of patients in the study was 25.87±10.7 years (range 17–61 years). Of the forty eight patients in the study there were 13 females (27.1%) and thirty five males (72.9%).There was statistically significant difference between blunt abdominal trauma scoring system (BATSS) and types of injury p<0.001. There was no statistically significant difference between blunt abdominal trauma scoring system (BATSS) and each of patients' sex and causes of injury p>0.05. Conclusion: The BATSS score system can be used as an initial screening to predict blunt abdominal trauma outcome and can be the basis of management in patients who experience blunt abdominal trauma

    Objective: To investigate the effect of adding metformin to clomiphene citrate (CC) in polycystic ovarian syndrome (PCOS) patients with acanthosis nigricans (AN) who were previously not responding to CC. Material and Methods: A double blinded randomized controlled trial (NCT02562664) included 66 PCOS women with acanthosis nigricans who were CC resistant (at least 3 months). Day 3 follicle stimulating hormone (FSH) level, fasting insulin, fasting glucose and homeostatic model assessment were used to quantify insulin resistance. Participants were randomly assigned to either group I (CC with placebo tablets) or group II (CC with metformin) for three cycles. Insulin resistance parameters as well as clinical pregnancy rate had been evaluated in both groups. The statistical analysis was done using Chi- square and Fischer exact tests. Results: The demographic data was comparable in both groups, however; there was higher cumulative pregnancy rate after three cycles of stimulation in group II (18/33) (54.5%) in comparison with group I (7/33) (21.1%) (P=0.03). There was a significant improvement in the insulin resistance parameters after three months of combining clomiphene citrate with metformin as compared with CC alone. Conclusion: Adding metformin to CC in clomiphene citrate resistant PCOS patients who have acanthosis nigricans improves the pregnancy rate and insulin resistant parameters
