Abstract
Sporosarcina pasteurii, a common soil bacterium has been tested for microbial treatment of cement mortar. The present study also seeks to investigate the effects of growth medium, bacterial concentration and different buffers concerning the preparation of bacterial suspensions on the compressive strength of cement mortar. Two growth media, six different suspensions and two bacterial concentrations were used in the study. The influence of growth medium on calcification efficiency of S. pasteurii was insignificant. Significant improvement in the compressive as well as the tensile strength of cement mortar was observed. Microbial mineral precipitation visualized by Scanning Electron Microscopy (SEM) shows fibrous material that increased the strength of cement mortar. Formation of thin strands of fillers observed through SEM micrographs improves the pore structure, impermeability and thus the compressive as well as the tensile strengths of the cement mortar. The type of substrate and its molarity have a significant influence on the strength of cement mortar.

Abstract
Several advantages have been suggested for producing sexed sperms including using fewer and genetically superior female animals for replacement.Four hundred active ovaries collected from the slaughter house of Al-shu'alah, the number and type of oocytes, ratios of maturation and fertilization shown that there was a significant difference in the numbers of oocytes (P<0.05) between right and left ovaries. A high recovery rate was obtained of good oocyte (Grade A) 42.35% (432/1020), fair oocyte (Grade B) 37.54% (383/1020) followed by and poor oocyte (Grade C) 17.84% (182/1020). There was a significant difference (P<0.05) between the 3 different grades. grades A and B oocytes, (815/1020) 79.9% of recovered oocytes were cultured. Maturation rate was 86.38% (704/815).Y- Bearing sperms separation applied by using procedure of the modified albumin technique; either one (8%) or two layers (8 and 16%) of BSA (M1, and M2) at 200, 300 or 400 xg, then used for in vitro fertilization.The in vitro fertilization rate observed was 21.8% (132/604) of matured oocytes by choosing universal primers from sequences that are highly conserved in the X and Y chromosomes, sex-specific sequences were successfully amplified in embryonic lysates. Bovine serum albumin sexed sperms result in more percentage of male embryos by using one layer of BSA ( 8%) at 200 × g (M1a) and 300× g (M1b) which were 72.7% and 54.5% respectively, and shows a deviation (p<0.05) from the 50% expected percentage for male and female embryos. While using two layer of BSA (16% and 8% BSA) at the 200 × g (M2a) and at 300× g (M2b) were 81.8% and 63.6% respectively. When we compare the rate of male embryos produced from IVF by sperms isolated by two layers of BSA (M2a, and M2b), moderate results obtained with M2b (63.6%) while the best results were with M2a separation protocol (81.8%).

Abstract
Approximately 27% of North American cancer deaths are attributable to cancer of the lung. Many lung cancers are found at an advanced stage, rendering the tumours inoperable and the patients palliative. Common symptoms associated with palliative lung cancer include cough, hemoptysis, and dyspnea, all of which can significantly debilitate and diminish quality of life (QOL). In studies of the effects of cancer therapies, the frequent evaluative endpoints are survival and local control; however, it is imperative that clinical trials with palliative patients also have a QOL focus when a cure is unattainable. We conducted a literature review to investigate the use of QOL instrument tools in trials studying QOL or symptom palliation of primary lung cancer or lung metastases through the use of radiotherapy. We identified forty-three studies: nineteen used a QOL tool, and twenty-four examined symptom palliation without the use of a QOL instrument. The European Organization for Research and Treatment of Cancer (eortc) QLQ-C30 survey was the most commonly used QOL questionnaire (in thirteen of twenty trials). Of those thirteen studies, eight also incorporated the lung-specific QOL survey eortc QLQ-LC13 (or the eortc QLQ-LC17). A second lung-specific survey, the Functional Assessment of Cancer Therapy-Lung (fact-L) was used in only two of the twenty trials. In total, only ten of forty-three trials (23%) used a lung-specific QOL tool, suggesting that QOL was of low priority as an endpoint and that measures created for lung cancer patients are underused. We encourage investigators in future trials to include specific QOL instruments such as the eortc QLQ-LC13 or the fact-L for studies in palliative thoracic radiotherapy because those instruments provide a measure of QOL specific to patients with lung cancer or lung metastases.

Abstract
Purpose Symptom clusters (scs) are a dynamic construct. They consist of at least 2 or 3 interrelated symptoms that may be a significant predictor of patient morbidity. In a previous study, we identified 2 scs in patients with bone metastases: These scs may be clinically important in the pain and symptom management of patients with metastatic bone pain. It is therefore important to validate the reported scs to determine if they hold true across similar patient populations. Patients and Methods From February to September 2007, our study accrued 52 patients with bone metastases [29 men (56%), 23 women (44%); median age: 68.5 years (range: 39–87 years)] who were referred for palliative radiotherapy (rt). Prostate (31%), breast (29%), and lung (19%) were the most common primary cancer sites. Treatment arms ranged from single to multiple fractions, with most patients receiving a single 8-Gy fraction (77%) or 20 Gy in 5 fractions (21%). The most prevalent sites for rt were spine (42%), hips (17%), and pelvis (14%). Worst pain at the site of rt and functional interference scores were assessed using the Brief Pain Inventory (bpi), a multidimensional pain instrument that uses 11-point numeric rating scales. Patients provided their symptom severity scores on the bpi at baseline and at 4, 8, and 12 weeks post rt. At all time points, a principal component analysis with varimax rotation was performed on 8 items (worst pain and 7 functional interference items) to determine relationships between symptoms before and after rt for bone pain. Results Two scs were identified. Cluster 1 included worst pain and interference with general activity, normal work, and walking ability; cluster 2 consisted of interference with mood, sleep, enjoyment of life, and relations with others. Our statistical analysis produced varied results for the 2 clusters found in our previous investigation. These differences may be an indicator for the instability of scs or may be a result of the fewer number of patients accrued in the present validation study. Conclusions The scs in our two studies were not identical for patients receiving palliative rt for symptomatic bone metastases. Another sc validation study should be conducted with a larger sample before a conclusion is drawn about the existence of an unstable phenomenon in sc research.

Abstract
In this retrospective analysis, the effect of currently used treatments in 26 patients with psoriasis of the palms and soles were analyzed. In general, patients are treated initially with topical medications including superpotent topical corticosteroids in combination with calcipotriene ointment or tazarotene gel or both. If satisfactory improvement is not achieved in 4-8 weeks, systemic retinoids are added, formerly etretinate and currently acitretin, except in women of childbearing potential. If the latter regimen is not effective within two months, soak PUVA is added to the regimen of oral retinoids and topical medications. If improvement is inadequate, or if the treatment regimen is not tolerated, methotrexate or cyclosporine have been added in the past. The availability of the excimer laser has recently modified our approach so that this therapy is used in combination with acitretin before soak PUVA. With the availability of biologic agents, methotrexate is avoided because of its hepatotoxicity and bone marrow toxicity and cyclosporine is avoided because of its nephrotoxicity. If oral acitretin plus topical therapy is not adequate to control the disease and the excimer laser is not an option because of its limited availability, alefacept, etanercept and infliximab are added when possible. Other biologic agents are likely to be added to this list in the future.

Abstract
PURPOSE Reports investigating whether the response rates to palliative radiation therapy (RT) for painful bone metastases from gastrointestinal (GI) cancers are similar to rates for bone metastases from other primary cancer sites have been limited. The present study evaluated response rates for symptomatic bone metastases from gi cancers after palliative outpatient rt in the Rapid Response Radiotherapy Program (RRRP). PATIENTS AND METHODS We identified 69 patients with bone metastases from gi primaries who received palliative rt in the RRRP clinic during 1999-2006. We extracted records for 31 of these patients during 1999-2003 from an RRRP database that used the Edmonton Symptom Assessment Scale (ESAS). Record for the remaining 38 patients during 2003-2006 were extracted from an RRRP database that used the Brief Pain Inventory (BPI). Eligibility criteria for encryption in the two RRRP databases and for collection of patient demographic information (age, sex, primary cancer site, and Karnofsky performance status) were identical. Response rates for this cohort of metastatic gi patients were then compared to rates for 479 patients receiving palliative RT for bone metastases from other primary cancer sites. Pain scores from the ESAS and BPI and data on analgesic consumption were collected at baseline and by telephone follow-up at 4, 8, and 12 weeks after RT for all patients. Complete (CR), partial (PR), and overall (CR+PR) responses were evaluated according to International Consensus Endpoints. RESULTS Assessment of the 69 patients with metastatic GI cancers revealed CR, PR, and CR+PR rates of 18%, 42%, and 61% at 4 weeks; 22%, 35%, and 57% at 8 weeks; and 50%, 21%, and 71% at 12 weeks for evaluable patients. The 479 evaluable patients with metastatic cancer from other primary cancer sites had CR, PR, and CR+PR rates of 25%, 27%, and 51% at 4 weeks; 26%, 22%, and 48% at 8 weeks; and 22%, 29%, and 51% at 12 weeks. No statistically significant differences were observed in RT response rates for bone metastases from GI cancers than from other primary cancer sites. CONCLUSIONS After palliative RT, bone metastases from gi cancers demonstrate response rates that are similar to rates for metastases from other primary cancer sites. Patients with symptomatic bone metastases from GI malignancies should be referred for palliative RT as readily as patients with osseous metastases from other primary cancer sites.

Abstract
AIM To explore the presence of symptom clusters in patients with brain metastases. MATERIALS AND METHODS Patients with brain metastases referred to an outpatient palliative radiotherapy clinic were asked to rate their symptom distress using the Edmonton Symptom Assessment Scale (ESAS). Baseline demographic data were obtained. To determine interrelationships between symptoms, a principal component analysis with 'varimax rotation' was carried out on the nine ESAS items. Follow-up was carried out by telephone 1, 2, 4, 8 and 12 weeks after radiation. RESULTS Between January 1999 and January 2002, 170 patients with brain metastases provided complete baseline data on the ESAS. The most common primary cancer sites were lung, breast and gastrointestinal. Fatigue was the highest scored symptom, followed by a poor sense of well-being, anxiety, drowsiness and poor appetite. The four most prevalent symptoms were fatigue (91.7%), a poor sense of well-being (88.1%), drowsiness (82.2%) and anxiety (82.1%). Three symptom clusters were found at baseline. Cluster 1 included fatigue, drowsiness, shortness of breath and pain. Cluster 2 included anxiety and depression. Cluster 3 included poor appetite, nausea and a poor sense of well-being. Fatigue, nausea, drowsiness and poor appetite showed an overall increase in symptom severity over time; whereas fatigue, drowsiness and poor appetite were experienced to some extent by a greater proportion of patients at week 12 compared with baseline. Symptom clusters emerged in all weeks of follow-up, but consisted of different symptoms in each week. CONCLUSION Symptom clusters seemed to exist in patients with brain metastases before and after whole brain radiotherapy. However, different symptoms clustered at various time points. The effectiveness of whole brain radiotherapy in providing palliative relief to patients with brain metastases needs to be explored with regards to symptom clusters.

Abstract
The penal laws in Pakistan went through sweeping reforms in 1979 with intent to bring them in line with the Islamic Jurisprudence. The introduction of these laws repealed the definitions as well as punishments of various types of injuries. Besides that these laws also redefined and reclassified the crime of murder. The laws required that the injuries be identified and documented by an authorized physician. The new classification of injuries and deaths, lack of proper forensic training of the emergency room physicians, performance of medicolegal work by doctors at the earliest stages of their careers and theoretical methods of undergraduate teaching in forensic medicine are matters of concern as they adversely affect the quality of medicolegal work performed in the country. This article gives an overview of the medicolegal system of Pakistan. It also reviews the current laws, their impact on the medical and legal systems of the country and offers some recommendations to correct the existing situation of forensic training and work standards.
