Abstract
Dieulafoy's lesion accounts for 1-5.8% of cases of acute upper GI bleeding. The two largest retrospective series, both from North America, found Dieulafoy's lesion as the source of hemorrhage in 1.9% and 1.2% of all endoscopies performed for acute GI bleeding. In the prospective study of Chung et al., Dieulafoy's Lesion was found in 3.4% of all patients with acute GI bleeding referred to their unit. The Dieulafoy's Lesion accounted for up to 40% of all causes of nonvariceal upper GI bleeding not caused by gastric or duodenal ulceration or esophageal varices in the prospective study of Matsui et al. In the study of Schmulewitz and Bailli, colonic Dieulafoy's Lesion were only found in 0.09% of all colonoscopies performed for lower GI bleeding. The actual incidence of both upper and lower GI bleeding from Dieulafoy's Lesion is likely higher than estimated because the diagnosis remains difficult. Recent advances in endoscopy have led to an increased detection of Dieulafoy's lesions. Initial GI endoscopy is effective in diagnosing up to 70% of patients. Several endoscopies may be required with 6% of patients, requiring three or more to establish the diagnosis. Angiography and/or red cell scanning can be used when endoscopy fails to diagnose a doubtful case. There is no definite unique policy for the treatment of Dieulafoy's lesions. Therapeutic endoscopy remains the first line of treatment option for controlling the bleeding while angiography is considered as a valuable alternative. Surgical intervention is kept for failure cases where it should be guided by preoperative localization. The mortality rate has decreased dramatically from 80% to 8.6% in recent times due to advancement in both diagnostic and therapeutic tools.

Abstract
Heart valve surgery in high-risk patients with severe jaundice, congestive hepatomegaly and renal impairment is associated with considerable morbidity and mortality. Without operation the consequences are invariably grave. A 35 years old gentleman with congestive cardiac failure was initially treated in coronary care unit (CCU). Mitral valve area was 0.5cm², pulmonary arterial systolic pressure (PASP) was 110mmHg, serum bilirubin was 20mg/dl, SGPT & SGOT were 1024iu/l and 1027iu/l respectively. Serum creatinine was 3.35mmol/l. Serum bilirubin gradually diminished to 3.1mg/dl after 12 days treatment in Coronary Care Unit but next day it increased to 3.6mg/dl. Mitral valve was replaced on an emergency basis. Echocardiogram on the 5th post operative day showed well functioning prosthetic mitral valve in situ. Serum bilirubin decreased to 2.2mg/dl, SGPT, SGOT and serum creatinine to 43iu/l, 40iu/l and 1.34mmol/l respectively. After 8 weeks of postoperative follow up his serum bilirubin decreased to 0.8mg/dl.

Abstract
This cross sectional descriptive study was to measure the thyroid angle and to establish the difference between sexes of different age groups in Bangladeshi cadaver. A total 60 human larynges were collected by purposive sampling from October 2008 to March 2009. Among them 45(male 23 and female 22) were collected from Bangladeshi cadavers (9 to 60 years) at the autopsy laboratory of Department of Forensic Medicine and 15 (male 6 and female 9) from stillborn infants of viable age (28 to 40 weeks of gestation) from Gynaecology and Obstetrics Department of Mymensingh Medical College, Mymensingh. The thyroid angle was measured and significant differences of the dimensions between different age and sex groups were observed. In the present study observed findings was compared with those of other researchers. The mean±SD thyroid angle was found as 65.00±11.65 degree in age Group A (28 to 40 weeks of gestation), 73.69±6.56 degree in age Group B (9 to 16 years) and 77.76±7.76 degree in age Group C (17 to 60 years). The mean thyroid angle was higher in female (83.1667±5.78220 degree) than that in male (73.9412±7.09460 degree) and statistically moderately significant in Group C, where t = 3.853 and p = 0.001. In statistical analysis, differences between age and sex groups were calculated by using Students (unpaired) 't' test. The present study revealed that the value was significantly greater in adult female than male and the value increased with age.

Abstract
PREMISE OF THE STUDY The results of published studies investigating the tissue-scale mechanical properties of plant cell walls are confounded by the unknown contributions of the middle lamella and the shape and size of each cell. However, due to their microscale size, cell walls have not yet been characterized at the wall fragment level under tensile loading. It is imperative to understand the stress-strain behavior of cell wall fragments to relate the wall's mechanical properties to its architecture. • METHODS This study reports a novel method used to characterize wall fragments under tensile loading. Cell wall fragments from onion outer epidermal peels were cut to the desired size (15 × 5 µm) using the focused ion beam milling technique, and these fragments were manipulated onto a microelectromechanical system (MEMS) tensile testing device. The stress-strain behavior of the wall fragments both in the major and minor growth directions were characterized in vacuo. • KEY RESULTS The measured mean modulus, fracture strength, and fracture strain in the major growth direction were 3.7 ± 0.8 GPa, 95.5 ± 24.1 MPa, and 3.0 ± 0.5%, respectively. The corresponding properties along the minor growth direction were 4.9 ± 1.2 GPa, 159 ± 48.4 MPa, and 3.8 ± 0.5%, respectively. • CONCLUSIONS The fracture strength and fracture strain were significantly different along the major and minor growth directions, the wall fragment level modulus of elasticity anisotropy for a dehydrated cell wall was 1.23, suggesting a limited anisotropy of the cell wall itself compared with tissue-scale results.

Abstract
This cross-sectional study was done to see the association of post thyroidectomy parathyroid failure with thyroid disease and type of surgery. It was carried out in the Department of Otolaryngology-Head and Neck Surgery, Bangabandhu Sheikh Mujib Medical University, Dhaka during the period of July 2008 to June 2010. Total 50 cases of thyroid malignancy and multinodular goiter who had undergone total or near total thyroidectomy with or without neck dissection were studied. In this study highest number of cases were found in 3rd decade of age (28%) and there was female predominance (M:F=1:3.54). Overall frequency of post operative hypocalcaemia was 30% (26% was temporary hypocalcaemia and 4% was permanent). Hypocalcaemia revealed clinically in 20% cases and remained subclinical in 10% cases. Hypocalcaemia developed in 42.30% cases of malignant thyroid disease and 16.66% cases of benign thyroid disease (p<0.05). It was found in 54.54% cases with neck dissection and 23.07% cases without neck dissection (p<0.05). Hypocalcaemia developed in 62.5% cases where parathyroid gland were not identified and 23.8% cases where parathyroid gland was identified. Hypocalcaemia developed most commonly on the 2nd post operative day (73.33%). There is a significance difference with development of parathyroid failure after thyroid surgery between benign and malignant thyroid disease and also between thyroid surgery with or without neck dissection.

Abstract
The present study has examined the association between ischemic stroke and hyperuricemia in Bangladeshi population. This age and sex matched case control study was carried out in the Department of Neurology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh during the period of January 2007 to December 2008. A total of 120 subjects were included in this study, among them 60 were cases and another 60 were controls. Data were collected purposively. Multiple logistic regressions were done to identify the risk factors for ischemic stroke. In this study 68.3% were male and 31.7% were female in both the groups. Male and female ratio of stroke patients was 2.16:1. Mean±SD of serum uric acid level of case and control group was 4.94±1.76 and 3.72±1.09 respectively. Among the case group 76.7% had normal and 23.3% had abnormal serum uric acid level. On the other hand, 93.3% respondents of control group had normal and 6.7% had abnormal serum uric acid (SUA) level. Significant differences was found between case and control group in term of SUA level (p<0.05). Since SUA level is a quantitative numerical variable, an increase in 1mg/dl has a 47.0% (95% CI 1.0% to 2.16%) increase in odds ratio (OR) of having ischemic stroke. This 47.0% is obtained by taking OR for uric acid-1. Elevated serum uric acid level is not significant for ischemic stroke among the Bangladeshi population.

Abstract
The successful outcome of an insemination is a combination of both male and female fertility-linked factors. We investigated the first service conception rate of cows at artificial insemination (AI) in the smallholder dairy farms in Bangladesh. Frozen straws were prepared from ejaculates of Bos indicus (n = 7) and Bos indicus × Bos taurus (n = 7) AI bulls. Fertility was determined from 6101 first services in cows that were performed by 18 technicians in four regions between April 2004 and March 2005. Pregnancy was diagnosed by rectal palpation between 60 and 90 days post-insemination. The Asian version of Artificial Insemination Database Application (AIDA ASIA) was used for bulls-, cows- and AI-related data recording, and later retrieved for analysis. The mean ± SD number of inseminations performed from individual bulls and their conception rates were 436.0 ± 21.6 and 50.7 ± 1.9%, respectively. Logistic regression demonstrated body condition scores (BCS), heat detection signs, months of AI and their interactions had greatest effects (odds ratios: 1.24-16.65, p < 0.04-0.001) on first service conception rate in cows. Fertility differed (p < 0.02-0.001) between the regions, previous calving months, months of AI, BCS, parity and heat detection signs of cows. Inseminations based on mounting activity (n = 2352), genital discharge (n = 3263) and restlessness and/or other signs (n = 486) yielded a conception rate of 53.6%, 48.8% and 50.1%, respectively (p < 0.05). Conception rate between technicians ranged between 43.4% and 58.6% (p < 0.05). The days interval from calving to first service (overall mean ± SD = 153.4 ± 80.6) had relationship (p < 0.001) with BCS, months of previous calving and parity of the cows. Fertility at AI in smallholder farms can be improved by training farmers on nutrition and reproductive management of the cows.

Abstract
Evaluating short-term (03 months) efficacy and safety of transurethral intraprostatic injection of absolute ethanol to treat benign prostatic hyperplasia (BPH). This intervention study was conducted to evaluate 30 patients with benign prostatic hyperplasia treated by transurethral injection of dehydrated ethanol. Mean age was 69.96 years. Endoscopic injection of 6-13.5 ml ethanol was carried out at 4-8 sites in the prostate. International Prostate Symptom Score (IPSS), maximum flow rate, prostate volume, postvoid residual and side effects or complications were measured postoperatively. Mean IPSS (SD) improved significantly from 18.43 ± 2.38 preoperatively to 6.80 ± 1.34 at 03 months of follow-up, mean peak urinary flow rate increased from 7.33 ± 1.19 ml/s to 16.31 ± 1.69 ml/s after 3 months, mean residual urine volume had decreased from 54.16 ± 30.93 ml to 17.01 ± 9.59 ml after 3 months (p<0.05). The prostate volume decreased from 44.66 ± 9.52 gm preoperatively to 32.46 ± 7.78 gm after 3 months (statistically significant at 5% level). There were no intra-operative complications but post-operative haematuria occurred in two patients, urinary retention occurred in two patients after removal of the catheter. Urinary tract infection developed in one patient. Transurethral ethanol ablation of prostate appears to be safe and cost effective. No occurrence of retrograde ejaculation was detected. The short-term effects of ethanol injection at prostate were satisfactory and acceptable as a minimally invasive therapeutic modality in selected patients.

Abstract
The trend of miniaturization has highlighted the problems of heat dissipation and electromigration in nanoelectronic device interconnects, but not amorphization. While amorphization is known to be a high pressure and/or temperature phenomenon, we argue that defect density is the key factor, while temperature and pressure are only the means. For nanoscale interconnects carrying modest current density, large vacancy concentrations may be generated without the necessity of high temperature or pressure due to the large fraction of grain boundaries and triple points. To investigate this hypothesis, we performed in situ transmission electron microscope (TEM) experiments on 200 nm thick (80 nm average grain size) aluminum specimens. Electron diffraction patterns indicate partial amorphization at modest current density of about 10(5) A cm(-2), which is too low to trigger electromigration. Since amorphization results in drastic decrease in mechanical ductility as well as electrical and thermal conductivity, further increase in current density to about 7 × 10(5) A cm(-2) resulted in brittle fracture failure. Our molecular dynamics (MD) simulations predict the formation of amorphous regions in response to large mechanical stresses (due to nanoscale grain size) and excess vacancies at the cathode side of the thin films. The findings of this study suggest that amorphization can precede electromigration and thereby play a vital role in the reliability of micro/nanoelectronic devices.

Abstract
This cross sectional descriptive study was done to observe the mean diameter of seminiferous tubules and to determine its differences between different age groups in Bangladeshi male. Thirty human testes of different age groups were collected by purposive sampling technique. Among them 22 specimens were collected from cadavers during routine postmortem examination and 8 specimens were from dead fetuses from Gynaecology & Obstetrics Department. The specimens were grouped into three categories Group A (28 to 42 weeks of gestational age), Group B (Up to 14 years) and Group C (15 to 70 years). The mean diameter of seminiferous tubules was measured and significant differences of the dimensions between different age groups were determined. The mean±SD diameter was 85.37±15.51 μm in Group A, 144.04±63.34 μm in Group B and 227.92±22.47 μm in Group C. Statistically, differences between age groups were calculated by using Unpaired Students 't' test. The present study revealed that the diameter increased with age and mean differences were statistically significant between Groups A&C, B&C and A&B.

Abstract
Multiferroic laminate composites consisting of chain-end cross-linked ferroelectric polymers and magnetostrictive Metglas are reported. The composites exhibit a greatly enhanced multiferroic voltage coefficient and sensitivity relative to analogous composites. These remarkable properties are attributed to high piezoelectric and electromechanical coupling coefficients, because of the formation of larger crystalline sizes and concurrent improvement in the polarization ordering in the cross-linked polymers.

Abstract
This intervention study was conducted to determine the efficacy of Levofloxacin in the treatment of uncomplicated enteric fever. Among 100 patients, who were purposively selected for the study had presented sign and symptoms of enteric fever with blood culture positive salmonella in laboratory findings during the admission in the department of Medicine, Uttara Adhunik Medical College & Hospital, Dhaka. Patients who fulfilled the diagnostic criteria were enrolled in the study and divided into two groups. One group was treated with oral levofloxacin 750mg once daily (OD) and another was injected with Levofloxacin 500mg once daily for 7 days. All the patients were examined twice daily to observe the clinical cure or failure of levofloxacin. Study was conducted from January 2008 to December 2008. Statistical analysis was performed by using statistical software SPSS version 12. Among the 100 patients in the study, majority of them 46(92%) were aged between 15 to 25 years, the next group was between 25 to 35 years 26(52%) and only three patients were aged above 65 years. Significant number of the patients were male (67), and the rest of them were female. The patients were clinically examined specially for anaemia, jaundice, caecal gurgling, hepatosplenomegaly in both the groups and the relevant investigations were performed. It was found that 46 patients in group A, who took oral levofloxacin, were cured after seven days, whereas 48 patients in group B were fully cured by taking injectable levofloxacin by seven days. In this study, levofloxacin was found to be the most effective drug in both oral and injectable form in one-week treatment of uncomplicated typhoid.

Abstract
Prevalence of organ failure is high through out the world. Organ transplantation, the definitive treatment option of organ failure keeps very low due to scarcity of organ. Most of the people are not aware about organ donation. Adolescent girls will be the mother of future nation and they can motivate family members for organ donation. This study was carried out to see attitudes towards organ donation and determine the negative factors of organ donation prevailing among school girls. One hundred sixty eight girls from class VIII to class X of a higher secondary school were participated. A structured questionnaire was filled up by the girls. The data were processed from questionnaire and analyzed. Among study population, most of them (64%) had no idea about on going organ donation and transplantation. The positive attitude of the girls towards organ donation was low when they are live (16%) and their attitudes also kept low even after their death (14%). The girls who did not agree to donate organ were further asked to mention the reasons. The reasons of negative attitude were religious belief, fear of illness and social and familial reservation. The result of this study suggests that among girls, awareness and attitudes about organ donation is poor. There were several reasons identified for low consent rates. Multidisciplinary actions should be taken to improve the awareness of the people about organ donation and motivate them for donation.

Abstract
Painful shoulder is a common painful condition among patients. Apart from acute traumatic lesions such as fractures, dislocations, contusions, sprains and ruptured tendons, 85 to 90% of painful shoulders are due to adhesive capsulitis, acute or chronic calcific tendinitis, bursitis, bicipital tendinitis and lesions of the musculotendinous cuff. Arthritis is the cause of less than 5% of painful shoulders. For evaluating conditions of shoulder joint, X-ray has been regarded as only method of choice for long time. Magnetic resonance imaging (MRI) is an alternative procedure but the cost limits its utilization especially in Bangladesh. Ultrasonography is an effective imaging modality in the evaluation of both rotator and non-rotator cuff disorders. Because of low cost and availability, it can be an alternative procedure for the diagnosis of painful shoulder. The present study was conducted to assess ultrasonography as a useful modality in evaluating cases of shoulder pain and to compare the findings with X-ray findings. Thirty two patients with shoulder pain were evaluated by X-ray and Ultrasonography (USG). Clinical diagnosis was done for correlation. To identify the cause of shoulder pain, 100% patients were found normal in plain X-ray. On Ultrasonography (USG) 12.5% patients had displaced long head of biceps, 21.9% had biceps tendinitis, and 3.1% had bursitis. In the assessment of shoulder pathology, USG had a sensitivity of 73.3%, specificity of 88.2%, Positive predictive value (PPV) of 84.6%, Negative predictive value (NPV) of 78.9% and an accuracy of 81.3%. USG is a useful modality for evaluation the shoulder joint in case of painful shoulder even plain X-ray is non conclusive.

Abstract
The amorphous to crystalline phase transformation process is typically known to take place at very high temperatures and facilitated by very high compressive stresses. In this study, we demonstrate crystallization of amorphous ultra-thin platinum films at room temperature under tensile stresses. Using a micro-electro-mechanical device, we applied up to 3% uniaxial tensile strain in 3-5 nm thick focused ion beam deposited platinum films supported by another 3-5 nm thick amorphous carbon film. The experiments were performed in situ inside a transmission electron microscope to acquire the bright field and selected area diffraction patterns. The platinum films were observed to crystallize irreversibly from an amorphous phase to face-centered cubic nanocrystals with average grain size of about 10 nm. Measurement of crystal spacing from electron diffraction patterns confirms large tensile residual stress in the platinum specimens. We propose that addition of the externally applied stress provides the activation energy needed to nucleate crystallization, while subsequent grain growth takes place through enhanced atomic and vacancy diffusion as an energetically favorable route towards stress relaxation at the nanoscale.

Abstract
This cross sectional descriptive study was performed by examining 30 (thirty) relatively fresh cerebellum. Out of them 20 postmortem human cerebellum collected from Bangladeshi cadavers of both sexes (male 10 and female 10) age ranging from 5 to 60 years and 10 cerebellums from caesarian section of dead fetuses of both sexes (male 6 and female 4) age ranging from 34 weeks to 41 weeks. Specimen containing cerebellum was collected from dead bodies autopsied on different dates from April'2009 to September'2009 at the autopsy laboratory of department of Forensic Medicine and Gynaecology and Obstetrics of Mymensingh Medical College, Mymensingh. Samples were collected by using nonprobability sampling technique. The collected sample was grouped in to three age groups like Group A (34 to 41 weeks of gestation), Group B (5 to 30 years) and Group C (31 to 60 years) and two sex groups (male and female). Ten cerebellums were studied from each age group for this histological study. Sections were processed following standard histological procedure and were stained with Hematoxylin and Eosin stain. Slides were examined under 15X40 magnifications and measurement of vertical and transverse diameter of the cell body were taken with the help of ocular micrometer. In this study, the mean difference of mean vertical and transverse diameter of Purkinje cell body between Groups A & B and Groups A & C was statistically highly significant (p<0.001) but differences between Groups B & C was statistically significant only in case of transverse diameter.

Abstract
In this study, methanol extract from the root bark of Calotropis gigantea L. and its petroleum ether (40°C-60°C), chloroform and ethyl acetate soluble fractions were tested for their cytotoxic activity against brine shrimp nauplii (Artemia salina, Leach) and for antifungal activity against Aspergillus flavus, Aspergillus niger, Penicillium sp and Trichoderma harzianum. Thin layer chromatography (TLC) screening showed that methanol extract and its different fractions contained different type compounds such as steroid, terpene, glycoside, heterocyclic and flavonoid. In brine shrimp lethality bioassay, it was found that chloroform fraction was highly cytotoxic (LD50 14.72 μg/ml) among the tested samples. Though methanol extract and ethyl acetate fraction have no activity against all the tested fungi but petroleum ether and chloroform fractions showed potent activity against Aspergillus niger, Penicillium sp, Trichoderma harzianum and Aspergillus niger, Trichoderma harzianum, respectively, in antifungal activity test.

Abstract
This cross-sectional study was done to assess the blood pressure of the senior citizens in relation to the anthropometric measurements and indices. It was conducted among the Bangladeshi elderly citizens of selected areas of Dhaka city. Samples were selected by convenient technique. A pre-tested questionnaire and a check list were used for data collection. Data analysis was done by SPSS for Windows. Three areas of Dhaka city namely Nakhal Para, Badda and Mirpur were selected in this study. The study was conducted during January to June 2006. A total of 317 samples were studied. Mean age of the respondents was 67.1 years (+/-6.6 SD). Mean SBP and DBP measured were 126 mm of Hg (+/-20 SD) and 72 mm of Hg (+/-12 SD), respectively. Among them, 33.1% were hypertensive on BP measurement; amongst which 32.4% had both SBP and DBP raised; 55.2% had isolated systolic hypertension and 12.4% had DBP raised. Of them 44.8% were identified finally as hypertensive considering BP measurement and those taking antihypertensive medication. The majority were well nourished and at less health risk in terms of BMI, WC and WHR. There was a tendency of being hypertensive with overweight/obese (p<0.05), high WC (male p<0.05 and female p<0.01) and high WHR (female p<0.001). Percentage of hypertensive was higher among the seniors of the study areas especially among those who were overweight/obese or at health risk by WC/WHR.

Abstract
The larynx is an organ of respiration and phonation. Larynx or Voice box is well developed in humans. The sound made by a human being using the vocal folds for talking, singing, laughing, crying, screaming etc. Pitch of the sound depends on the length, tension and mass of the vocal folds. This cross sectional descriptive type of study was done to see the length of the vocal folds and to establish the difference between sexes of adult Bangladeshi people. A total of 29 human larynges of adult age group ranging from 17 to 60 years in the both sexes were collected by purposive sampling during routine postmortem examination at the autopsy laboratory of Department of Forensic Medicine of Mymensingh Medical College, from October 2008 to March 2009. The mean length of vocal fold was measured and significance differences of the dimension between male and female were observed. In the present study observed finding was compared with those of other researchers. In male the mean(+/-SD) length of vocal fold was 23.12(+/-4.06) mm. In female the mean(+/-SD) length of vocal fold was 18.50(+/-2.39) mm. In statistical analysis, difference between male and female values was calculated by using Students (Unpaired) 't' test. The present study revealed that the value was greater in male than in female group and this difference was statistically significant (p<0.01).

Abstract
The aims of this study were to determine the total population of coliform bacteria in the samples collected from diarrhea associated patients from the local area of Bangladesh and to examine the antibacterial efficacy of leaf extracts of Moringa oleifera (Moringaceae) against the isolated coliform bacteria. The coliform bacteria detected in these samples by some microbial-biochemical tests such as Escherichia coli, Shigella dysenteriae, Salmonella sp., Enterobacter sp., Klebsiella pneumoniae and Serratia marcescens. The total isolation rate of coliform bacterial species was ranged from 38.01-3.51%. At the concentration of 300 ig/disc, the organic extracts of hexane, chloroform, ethyl acetate and methanol extracts of Moringa oleifera leaf exhibited a remarkable antibacterial effect against all the tested bacterial pathogens. The zones of inhibition against all the tested bacterial pathogens were found in the range of 8.0 to 23.2 mm, along with their respective minimum inhibitory concentration (MIC) values ranging from 62.5-1000 ig/mL. The results obtained in this study suggest that the extracts from Moringa oleifera leaf can be a source of natural antimicrobials with potential applications in pharmaceutical industry to control coliform bacteria.
