Back ground: X-chromosomal short tandem repeats (X-STRs) have assured to be informative and particular role in complex relationship testing. DXS6807 known as tetra nucleotides polymorphism representing eight alleles of 251-275 bp in length. DXS6807 is located in, at XP 22.2, at a genetic distance of more than 87 and 151 Cm of X-chromosome. DXS101 is located104.9–121 cM from the Xp-telomere (Xp-tel) corresponding to cytogenetic position in Xq21.33–Xq22.3.  Objective: The aim of this present study   investigates the allele frequency of two markers DXS101, DXS6807 and forensic efficiency parameters for sample of Arabic Iraqi males. Material and methods: The population of this study includes 200 males apparently healthy unrelated participants from different region of Baghdad city, their ages ranged between (20-50) years. The Genomic DNA extracted and purified successfully from blood samples.  Results: The forensic efficiency parameters result for these markers were following: polymorphism information content (PIC) of 0.834708, power of discrimination (PD) in male 0.851750, Power of exclusion (PE) 0.698316, MEC Krüger0.511679, MEC Kishida 0.694890. The forensic efficiency parameters analyzing from Arabic population were Power of discrimination (PD) = 0.73405, Polymorphism information content (PIC) =0.69489, Power of exclusion (PE) =0.482879.MEC Krüger =0.511679, MEC Kishida = 0.694890. Conclusions: The information provided establish this X-linked microsatellite marker as a valuable strategy for forensic application. DXS101is and DXS6807 recently consider more stable and suitable forensic markers for forensic application.

Cervical Lymph Nodes

A cross sectional study of 29 cases of oral squamous cell carcinoma with or without  cervical lymph node metastasis was done among Bangladeshi patients from January 2006 to December 2007. Majority of the study subjects (34.5%) belonged to the age group of 40-49 years. 58.6% of the study subjects were male, while remaining 41.4% of them were female. 51.7% of the lesions were located in the alveolar ridge where the other common sites were buccal mucosa (27.6%) and retro molar area (13.8%). Half of the study subjects (51.7%) were habituated to betel quid chewing followed by 37.9% and 10.3% were habituated to smoking and betel quid-smoking respectively. Grade I lesions was most prevalent (75.9%) in the study subjects.  Majority of cases presented with Stage IV lesions (55.2%). The sensitivity, specificity, positive predictive value, negative predictive value & accuracy of clinical palpation method for determining metastatic cervical lymph nodes were 93.33%, 64.29%, 73.68%, 90% and 79.3% respectively. Careful and repeated clinical palpation plays important role in evaluation of cervical lymph nodes though several modern techniques may help additionally in the management of oral cancer.DOI: http://dx.doi.org/10.3329/updcj.v1i2.13978 Update Dent.

Effective Interventions

Introduction. Thirst is a common symptom of chronic heart failure (CHF) patients. Difficulties to adherence with fluid restrictions are among the effects of thirst in HF patients and therefore have an impact on worsening condition, but intervention studies aimed specifically at reducing thirst in CHF are lacking.Purpose. Purpose of this manuscript is to assess the effective intervention to reduce thirst intensity in CHF patients.Methods. Medline, Pubmed, EBSCO and hand search were searched using the key words thirst, intervention, heart failure, CHF, fluis restriction, therapy.Result.� Eighteen articles were found, six studies were inluded. Any kind of interventions in each articles, include: drink cold water 5oC, chewing gum, saliva substitute, sucking ice cubes and three bundle of interventions (oral swab, water sprays and menthol moisturizer).Conclusions. The most effective interventions to alleviate thirst was sucking ice cubes. But, no intervention studies were found in congestive heart failure patients. So investigations in people with heart failure is needed.�Keywords: thirst, intervention, heart failure, systematic review
