Abstract
Anagallis arvensis L. has several health benefits, such as it is an effective remedy for epileptic disorders, leprosy, rheumatism, and hepatic and renal dysfunctions. However, scientific evidence of the plant against liver disease is not reported so far. Thus, the aim of the present study was to highlight the hepatoprotective and hepatocurative effect of extract on hepatic injury induced by carbon tetrachloride (CCl4). The extract was investigated for its effect on hematological parameters, liver enzymes regulation, and anti-oxidant markers (SOD & CAT). In addition, histopathological investigations were performed. This extract displayed significant reversion of WBCs, RBCs, platelets count, hemoglobin, ALT, AST, ALP and albumin levels towards the normal level as compared with control. Therefore, there was significant rise in level of SOD and CAT in both groups (hepatocurative and protective). Furthermore, histological investigation demonstrated the preventive effect. The presence of alkaloids, carbohydrates, protein, phenolic compounds, tannins and saponins in the extract was confirmed by the preliminary phytochemical studies. Thus, based on all these facts, it can be concluded that Anagallis arvensis extract has restorative capability against CCl4-induced hepatotoxicity and could be used as the hepatocurative and hepatoprotective agent, which could be attributed to the reported secondary metabolites.

Abstract
INTRODUCTION Coeliac disease can occur at any age but is more common in children. Its diagnosis requires correlation between clinical presentations, serological results, endoscopic findings and histopathological classification using the modified Marsh grading system. This study of coeliac disease with biopsies received in the department of histopathology at Soba University Hospital, and Fedail Hospital aimed to gain insight into the demographic profile, clinical presentations and histopathological classification of patients with coeliac disease. METHODS This was a descriptive study carried out at Soba University Hospital and Fedail Hospital during the period from January 2010-December 2013. Haematoxylin & Eosin and CD3-stained slides of small intestinal biopsies of coeliac disease patients were reviewed for various histological features (1) intraepithelial lymphocytes (IEL) count per 100 enterocytes, (2) crypt hyperplasia and (3) degree of villous atrophy. Based on the histopathological findings, the cases were categorized according to the modified Marsh classification. Demographic and clinical data were obtained from the patient request forms. The data were analyzed using Statistical Package for Social Sciences Software (SPSS). RESULTS The study included 60 patients. Their age ranged from 2 to 70 years with a mean of 19.5 years (±15.7 SD). The most common age group was below 10 years old (41.6%). Male and female are equally affected. The most common clinical presentation was chronic diarrhoea (55.0%), followed by iron deficiency anemia (41.7%). The degree of villous atrophy ranged from complete atrophy (45.0%), marked atrophy (38.3%) to mild atrophy (16.6%). Marsh grade IIIC was the most common grade. The younger age-groups had a higher prevalence of iron deficiency anaemia and higher Marsh grade.

Abstract
Allele frequency distributions of nine short tandem repeat (STR) loci, D3S1358, vWA, FGA, D8S1179, D21S11, D18S51, D5S818, D7S820, and D13S317, HLA-DQA1 and polymarker (PM) loci were studied in a sample population from Sultanate of Oman, Middle East. Blood samples were collected from 162 unrelated individuals. For all STR, HLA-DQA1 and PM loci, no deviations from Hardy-Weinberg equilibrium, based on the exact test, were observed. The most discriminating loci were D18S51 (PD=0.966) and FGA (PD=0.964), while the least informative locus is GYPA (PD=0.585). The allele frequency data may be useful in forensic case work.

Abstract
This study demonstrates that the locus D1S80 is highly polymorphic in the Bahrainian population. There were 24 different D1S80 alleles and 51 distinct genotypes observed in 198 Bahrainians. There was one allele observed that was smaller than the 14 repeat allele. This data set meets the Hardy-Weinberg expectations (HWE) and could be a useful marker for parentage testing and forensic applications.

Abstract
Allele frequency data for eight short tandem repeat (STR) loci, HUMF13A01, HUMFESFPS, HUMF13B, HUMLPL, HUMCSF1PO, HUMTPOX, HUMTHO1 and HUMvWA, were obtained for unrelated individuals in a Saudi Arabian population. All loci, except F13B (P = 0.037) and LPL (P = 0.035), meet Hardy-Weinberg expectations, based on the exact test. The most informative locus is HUMvWA (PD = 0.936) and the least discriminating is the HUMTPOX locus (PD = 0.820). There was only one observation of a departure from expectation from pairwise locus comparisons. These data can be used for estimating the frequency of STR profiles in a Saudi Arabian population.

Abstract
Alu insertion polymorphisms (polymorphisms consisting of the presence/absence of an Alu element at a particular chromosomal location) offer several advantages over other nuclear DNA polymorphisms for human evolution studies. First, they are typed by rapid, simple, PCR-based assays; second, they are stable polymorphisms-newly inserted Alu elements rarely undergo deletion; third, the presence of an Alu element represents identity by descent-the probability that different Alu elements would independently insert into the exact same chromosomal location is negligible; and fourth, the ancestral state is known with certainty to be the absence of an Alu element. We report here a study of 8 loci in 1500 individuals from 34 worldwide populations. African populations exhibit the most between-population differentiation, and the population tree is rooted in Africa; moreover, the estimated effective time of separation of African versus non-African populations is 137,000 +/- 15,000 years ago, in accordance with other genetic data. However, a principal coordinates analysis indicates that populations from Sahul (Australia and New Guinea) are nearly as close to the hypothetical ancestor as are African populations, suggesting that there was an early expansion of tropical populations of our species. An analysis of heterozygosity versus genetic distance suggests that African populations have had a larger effective population size than non-African populations. Overall, these results support the African origin of modern humans in that an earlier expansion of the ancestors of African populations is indicated.

Randomly collected blood samples from 100 Arabs and 100 Pakistanis residing in Abu Dhabi were analyzed using the HLA-DQ alpha and polymarker (LDLR, GC, GYPA, HBGG, D7S8) PCR based reverse dot blot systems. Allelic frequencies for each allele and observed heterozygosity for each locus were calculated. Departures from Hardy-Weinberg expectations (HWE) were determined using the unbiased estimate of the expected homozygote/ heterozygote frequencies, the likelihood ratio test and the exact test. No significant departures from HWE expectations were detected.

Abstract
In preparation for the application of restriction fragment length polymorphism (RFLP) analysis methods to casework, validation studies were performed at the Indianapolis-Marion County Forensic Services Agency (IMCFSA). They encompassed the following areas: standard specimens, sample consistency, reproducibility, mixed specimens, environmental insults, minimum sample requirements, non-probative casework, repetitive sizing accuracy, precision and match criteria analysis, and population studies including K562 data analysis. All studies yielded results as expected, were consistent with those previously reported by other laboratories, and formed a strong foundation on which to base future casework analysis.

The deoxyribonucleic acid (DNA) typing of human Leukocyte Antigen (HLA) DQ alpha from human fingernails is described. HLA-DQ alpha genotypes can be accurately determined from clipped fingernails. We have typed 26 nails accurately, while one did not give any type since that one sample did not amplify due to the low quantity of DNA. The cut off limit for the digested material to be amplified is approximately 9 mgs of nail material.

Abstract
The restriction fragment length polymorphism (RFLP) analysis of blood, semen, and other body fluids, has become increasingly important in violent criminal cases. The identification of additional tissues suitable for comparison with suspected donors has obvious potential benefit. One type of tissue, that found in nasal secretions, has previously received little attention with regards to genetic analysis. We collected blood and nasal secretion samples from eight individuals, subjected them to traditional RFLP typing methods, and analyzed the results using probes for loci D2S44, D1S7, D10S28, D4S139, and D17S79. All nasal samples provided high DNA yields and hybridization results that matched the corresponding blood standards. Thus, nasal secretions are shown to have potentially significant evidentiary value.

Abstract
An absorption inhibition method for the detection of gamma marker Gm(11) in dried bloodstains is described. Particular reference is made to the association of Gm(11) with Gm(-1, -2). When a dried bloodstain fails to inhibit anti-Gm(1) and anti-Gm(2), this may represent a true Gm(-1, -2) result or there may be insufficient material to inhibit either antibody. The detection of Gm(11) in a bloodstain extract provides an objective means of confirming the apparent absence of Gm(1) and Gm(2) as representing a true Gm(-1, -2) result. This antigen compares very well with other blood group systems with regard to the amount of bloodstain required for analysis and its stability. No evidence is available for preferential loss of Gm(1) and Gm(2) relative to Gm(11) in dried bloodstains.

In each case, the hairs were typed first for EAP and then confirmed by typing the blood from the same donors. Of the 150 donors checked, EAP activity was found in 135 of the samples; the other 15 samples showed no activity because they contained no sheath cells. Of the 135 samples showing activity, 108 of those were typed accurately in EAP. The remaining 27 samples had EAP activity but with inconclusive findings. In this study, all six common phenotypes were encountered.

Abstract
Weanling male rabbits were fed either: 1) a complete diet ad libitum (control); 2) a maintenance diet; or 3) a sub-maintenance diet. After 20 days, half of each group was slaughtered and the remainder was placed on treatment 1 until they achieved the same body weights as the controls (about 30 more days), when they were also killed. Body organs, including livers, hearts, lungs and kidneys, were significantly reduced in weight by nutritional stress. Maintenance and sub-maintenance feeding resulted in creases in ultimate muscle pH, water content and alkali-soluble and -insoluble stromal proteins. The intracellular proteins, especially the myofibrillar fraction, decreased markedly, depending on the degree of nutritional stress. Swelling of the stromal proteins was less for the underfed rabbits, indicating that nutritional stress increased the number of acid-stable corss-linkages. Calcium-induced contraction was not effected by any of the nutritional treatments. Blood enzymes were not affected by nutritional stress from the standpoint of their multiple molecular forms, mobility or band profiles. All differences in muscle characteristics disappeared during compensatory growth except for the increased amount of alkali-insoluble stroma protein. The concepts of labile, mobilizable and fixed body proteins are discussed.
