Abstract
Lung cancer is one of the most common malignancies in the world. Its incidence and mortality rates are on the rise in Pakistan. However, epidemiological studies to identify common lung cancer determinants in the Pakistani population have been limited. In this study, data of 440 cases and 323 controls were collected from different hospitals in Peshawar and Islamabad, along with information about socio-demographic factors including age, sex and smoking. Univariate and multi-factorial analyses of socio-demographic factors in association with each other were also performed. Overall survival analysis highlighted that, out of 440 patients in the lung cancer dataset, 204 people were uncensored with a median survival time of 13 months (95% CI=12-18). There were 41 femaleand 399 male patients. Differences were observed between length of survival in the males and females (χ12 = 6.1; p-value = 0.01). Gender was observed to be significantly related to survival (p-value< 0.01), with better survival in females (hazard ratio=2). Cox regression was extended to adjust for the covariate age (z = 2.5; p-value = 0.02). Survival analysis was also performed on the basis of smoking groups (current smokers, former smokers and never smoked individuals) and smoking duration (smoking duration>10 years, <10 years and never smoked). Smoking duration was significantly associated with survival (p-value < 0.01), with better survival in never smokers in comparison to both smoking for greater or less than 10 years. Strong associations were observed for smoking group with duration greater than 10 years, OR=6.1(3.9-9.5) on univariate and multi-factorial analysis OR=11.3(CI=6.8-19.3).

Abstract
There have been an association between systemic diseases and hormonal changes particularly diabetes which has been cited as a risk factor in the progression of periodontitis in pregnant women. The incidence and severity of periodontal diseases are increasing at a higher rate and a common condition in pregnant diabetic women among Bangladeshi population. This cross sectional study included 200 pregnant women who were selected from gynecological department and examined at the dental unit. The clinical parameters used were the Silness and Loe plaque index (PI), gingival scores and periodontal status and any relationship to socio demographic variables (age, occupation, level of education and urban or rural residence) and clinical variables (gestation period, previous pregnancy, type of diabetes and periodontal maintenance) were evaluated. The results showed that these clinical parameters increased concomitantly with an increase in the stage of pregnancy and in women with multiple pregnancies. Increased age, lower level of education, unemployment and patients residing in rural areas were associated with significantly higher gingival scores and periodontal measures. Women with increased age and multiple pregnancies usually have less interest to frequent periodontal maintenance showing a significant statistical relation between an increased age and changes in gingival and periodontal status; however no significant association was found between increased age and plaque index. It is concluded that gingival inflammatory symptoms are aggravated during pregnancy in diabetic women and are related to different clinical and demographic variables.

Abstract
Coronary Angiogram (CAG) has been used to detect coronary artery disease in myocardial infarction (both STEMI and NSTEMI) patients. The purpose of this study was to compare the degree of coronary artery disease among STEMI and NSTEMI patients. Among acute coronary syndrome in NSTEMI we found more widespread coronary artery disease other than STEMI. Lack of documentations encouraged us to perform this study in our center. In this retrospective observational study we summarized all myocardial infarction (MI) patients who underwent coronary angiography (CAG) from August 2013 to August 2014 at Enam Medical College Hospital, Dhaka, Bangladesh and data of degree of coronary artery disease were recorded. Data of 100 consecutive MI patients who underwent CAG during that period were recorded. Among them 50 patients having STEMI as Group I (male 45, female 5) & other 50 patients sustained NSTEMI as Group II (male 38, female 12). Among NSTEMI patient group 80% were having multi-vessel disease and in STEMI patient group 80% having single vessel disease and remaining having multi-vessel disease. The degree of coronary artery disease is extensive in NSTEMI patients than in STEMI group. Coronary angiogram can visualize the degree of coronary artery involvement and is a useful screening modality to compare disease extent in MI patients.

Abstract
Prostate adenocarcinoma is one of the leading causes of cancer related mortality in men but still limited knowledge is available about its associated functional SNPs including rs1042522 (Pro72Arg). The present study was undertaken to explore the association of this SNP with susceptibility to prostate adenocarcinoma along with its structural and functional impacts in the Pakistani population in a case-control study. Three-dimensional structure of human TP53 with Pro72Arg polymorphism was predicted through homology modeling, refined and validated for detailed structure-based assessment. We also carried out a HuGE review of the previous available data for this polymorphism. Different genetic models were used to evaluate the genotypes association with the increased risk of PCa (Allelic contrast: OR=0.0.34, 95%CI 0.24-0.50, p=0.000; GG vs CC: OR=0.17, 95%CI 0.08-0.38, p=0.000; Homozygous: OR=0.08, 95%CI 0.04-0.15, p=0.000; GC vs CC: OR=2.14, 95%CI 1.01-4.51, p=0.046; Recessive model: OR=0.10, 95%CI 0.05-0.18, p=0.000; Log Additive: OR=3.54, 95%CI 2.13-5.89, p=0.000) except the Dominant model (OR=0.77, 95%CI 0.39-1.52, p=0.46). Structure and functional analysis revealed that the SNP in the proline rich domain is responsible for interaction with HRMT1L2 and WWOX. In conclusion, it was observed that the Arg coding G allele is highly associated with increased risk of prostate adenocarcinoma in the Pakistani population (p=0.000).

Abstract
The major blood supply to long bones occurs through the nutrient arteries, which enter through the nutrient foramen. The supply of nutrient artery starts during the early phases of ossification. It is essential in operative procedures such as bone graft, tumour resection, trauma healing and bone transplant techniques both in orthopedics and micro vascular surgery. The present study is an observational analytic type of study which was performed on two hundred (n=200; male=117 & female=83) left sided dry humerus bones. In this present study the majority of the bones had a single nutrient foramen which may represent a single source of blood supply. The location of the nutrient foramen is predominant on the antero-medial aspect of humerus. The position of the nutrient foramen is predominant on the middle 1/5th of the shaft humerus. There was no significant difference (p=0.319) in presence, absence, number, location and position of nutrient foramen in male and female left human humerus. This study and recorded data may help in surgical procedures in orthopedics and in micro vascular surgery.

Abstract
BACKGROUND Breast cancer is the most common female malignancy worldwide and its incidence is on the rise in Pakistan. The aim of this case-control study was to quantify the association of various risk factors with breast cancer risk among Pakistani women. MATERIALS AND METHODS A total of 2,246 women were studied, including 1,238 women with histologically confirmed breast cancer patients and age matched control subjects (N=1008) without breast cancer and other chronic diseases. Subjects were interviewed using a specifically designed questionnaire. Unconditional logistic regression was applied. Subsequent disease-specific mortality was also measured. RESULTS In this study, majority of the breast cancer patients (69.59%) were in age ranges of 40s and 50s. BMI greater than 25kg/m2 (OR=1.57; 95%CI, 1.26-1.90 and OR=1.60; 95%CI, 1.26-2.03), marital status of unmarried (OR=2.03; 95%CI, 1.69-2.44), lack of breast feeding, smoking (current or ever), lack of physical activity and post-menopausal status were found to have significant positive associations with breast cancer. It was also observed that increased parity reduced the disease risk. A larger number of cases (58.1%) had their right breast affected while 22.8% had other complications as well. CONCLUSIONS This exploratory analysis indicated a number of risk factors to be associated with increased risk of breast cancer. It was also observed that mean age at diagnosis is a decade earlier than in western countries. It is hoped that our findings will facilitate establishment of adequate evidence-based awareness and preventive measures for Pakistani women.

Abstract
This case control study was done to ascertain the association between exposures to biomass cooking fuel smoke and pulmonary tuberculosis. Cases were all newly diagnosed pulmonary tuberculosis patients, randomly collected from the Hospital (DOTS centers) Registry from January 2012 to June 2012 from two Upazillas of Sirajganj district, Bangladesh. A home visitation program was done subsequently. Healthy controls were recruited from the neighbourhood of each case through a predefined procedure. Total 276 new pulmonary tuberculosis cases and 276 neighbourhood controls were enrolled. A semi-structured questionnaire containing demographic information, smoking habits, cooking place, kitchen condition, use of biomass fuel for cooking was used for interview. Crude (unadjusted) odd ratios and their corresponding 95% confidence limits for independent variables were determined by binary logistic regression. All significant variables were entered into a multivariate conditional logistic regression model and a final fitted model was determined by backward elimination methods. In univariate analysis, member of a nuclear family {Unadjusted odd ratio (Unadj. OR) 1.570, 95% CI 1.008-2.44)}, having non-formal education (Unadj. OR 2.739, 95% CI 1.219, 6.153) or primary (Unadj. OR 3.407, 95% CI 1.492, 7.782) to secondary level (Unadj. OR 2.392, 95% CI 1.032, 5.544) education, using cow dung (Unadj. OR 3.961, 95% CI 1.267, 12.376) and biomass fuel i.e. plant origin (Unadj. OR 3.382, 95% CI 1.087, 10.518) for cooking, past smoker (Unadj. OR 2.504, 95% CI 1.061, 5.910), using open oven (Unadj. OR 3.109, 95% CI 0.995, 9.716), having small kitchen area (Unadj. OR 0.99, 95% CI 0.989, 0.999) all were significantly associated with tuberculosis. When all significant variables were entered into a multivariate conditional logistic regression model nuclear family {Adjusted odd ratio (Adj OR) 1.808, 95% CI 1.127, 2.9)}, primary level education (Adj OR 2.86, 95% CI 1.23, 6.647) and non formal education (Adj OR 2.312, 95% CI 1.013, 5.276), biomass fuel (plant origin, Adj OR 3.497, 95% CI 1.059, 11.55), and cow dung (Adj OR 4.368, 95% CI 1.319, 14.464)) used in cooking and irregular smoker (who stop smoking at least 6 month back) (Adj OR 2.806, 95% CI 1.141, 6.901) were significantly associated with tuberculosis cases. From this study significant association have been found between exposure to combustion of biomass cooking fuel and tuberculosis.

Abstract
People with rare hypertrichosis syndromes became crowd-drawing money-making phenomena in many 19th century sideshow acts. These individuals have been referred to as dog-men, hair-men, and werewolves. In 1993, Baumister et al. described congenital hypertrichosis lanuginose or Ambras syndrome: a distinct form of congenital hypertrichosis characterized by excessive hair growth over the body and face associated with facial and occasional dental anomalies. Much is not known about this syndrome since fewer than 50 cases have been documented worldwide. In this case report, a nine year old girl presented with excessive hair growth throughout her body that was denser along her midline. Furthermore, her face displayed the typical dysmorphic features characteristic of Ambras syndrome: a round tip nose, thickened nasal cartilage, antiverted nares, prominent philtrum with deep groove, and a trapezoid mouth. Oral examination revealed normal oral mucosa with completely missing and unerupted decidious and permanent teeth. Panoramic radiographs confirmed unerupted deciduous teeth. Previous case reports have mentioned the presence of occasional dental anomalies such as retarded first and second dentition and absence of some teeth. However, this is the first reported case of Ambras syndrome presenting with complete anodontia. Prior cytogenetic studies performed on persons with Ambras syndrome have implicated a balanced pericentric inversion of chromosome 8. However, it is likely that dental anomalies are likely a result of a different genetic rearrangement. Further studies are needed to explore the cause of this rare phenotype of Ambras syndrome with complete unerupted dentition.

Abstract
Disability adjusted life years (DALY) is the sum of the present value of future years of lifetime lost through premature mortality, and the present value of years of future life-time adjusted for the average severity of any mental or physical disability caused by a disease or injury. As a method for estimating the global burden of disease, DALY was first introduced in the World Development Report in 1993 by the World Bank. The aim of this study was to estimate DALY among arsenicosis patients. DALY was calculated for 104 arsenicosis patients from an arsenic-affected rural area of southern Bangladesh using the estimated years they lived with disability (YLD). The mean (SD) of cumulative arsenic exposure level was 5.0 (3.2) mg/l-years. Among the patients, 64% reported reduction in working ability. The portion of the patients with disability for more than 50 years was as high as 58.7%. The mean (SD) of YLD and DALY was 54.0 (9.8) and 9.2 (1.5), respectively. A total of 5621 YLD equivalent to 961.7 DALY was lost due to arsenicosis (when life expectancy at birth according to Bangladesh Bureau of Statistics was applied, the YLD and DALY were 3899.2 and 868.9, respectively). There was significant relationship of YLD with education of the patients (p < 0.05). There was significant relationship between DALY and education of the patients (p < 0.05). There was also significant relationship between DALY and reduction in working ability of the patients (p < 0.05). The findings of the study justify for the policy makers to adopt adequate measures such as prevention, treatment and rehabilitation to alleviate the sufferings of the arsenicosis patients.Mediscope Vol. 2, No. 1: 2015, Pages 4-12

Abstract
Background The study was designed to assess the prevalence of asymptomatic gallstone disease in North-East part of Bangladesh. Materials and methods Randomly selected asymptomatic persons, unknown to have gallstone disease, from both rural and urban areas were enrolled. They were subjected to abdominal ultrasonography and findings were recorded in a data sheet. Results Total 1,019 persons (316 males and 703 females) were examined. Age of them varied from 18 to 80 years with mean age of 37.22 years. Out of them, 61 (6%) persons were found to have gallstone. Among them, 14 were males and 47 were females. Both male and females of age below 40 years were more affected. Gallstone disease was found more commonly among housewives and middle class people. Among 61 patients with gallstone, seven were underweight (11.47%), 32 (52.45%) had normal weight and 22 (36.06%) were overweight, obese or extremely obese. But, this difference was not statistically significant (p = 0.894). Conclusion Prevalence of asymptomatic gallstone disease was found in 6% apparently healthy subjects of North-East part of Bangladesh. It was more prevalent among housewives and middle class group of population. It is also common among the people of age group below 40 years.

Abstract
Background Hepatitis C virus (HCV) is a major cause of liver cirrhosis and hepatocellular carcinoma and infects about 3% world population. Response to interferon therapy depends upon the genotype of the virus and factors associated with the host. Despite a good response to interferon therapy, a considerable number of genotype 3a infected patients remains unalleviated. Results In total forty-nine patients including twenty-five non-responders (non-SVR) and twenty-four responders (SVR) were recruited. Patients were tested for viral status at different intervals and the isolated RNA was sequenced for the NS5A region in both groups. The comparison of PKRBD of HCV between the SVR and non-SVR patients did not confirm any significant difference in the number of mutations. However, when the sequence downstream to the PKRBD of NS5A was compared, two important statistically significant mutations were observed; at positions 2309 (Ala to Ser) and 2326 (Gly to Ala). These mutations were then analysed for tertiary protein structure and important structural changes were observed. Statistically significant difference was also observed when age groups of patients were compared; younger patients showed better response than the older ones. Conclusions The region between PKRBD and IRRDR may be important for prediction of response to IFN therapy for genotype 3a. ISDR and PKRBD have not shown any involvement in treatment response. Further functional analyses of these findings can help in understanding the involvement of the NS5A region in interferon treatment of HCV-3a infected patients.

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
The study sought to compare procedural outcomes for patients undergoing percutaneous coronary intervention (PCI) of a chronic total coronary artery occlusion (CTO) with a matched non-CTO cohort. Percutaneous coronary intervention of a CTO is a common occurrence, and the outcome for patients with successful PCI of a CTO has not been clearly defined. Between November 2006 and December 2010, a total of 2,000 consecutive patients consecutively underwent PCI for a CTO. Utilizing propensity scoring methods, a matched non-CTO cohort of 2,000 patients was identified and compared to the CTO group. The cohorts were stratified as successful and failed procedures in United Hospital Limited Dhaka. The in-hospital major adverse cardiac event (MACE) rate was 3.8% in the CTO cohort. Technical success has improved over the last 10 years (overall 74.4%, slope 1.0%/year, p=0.02, R²=49.9%) as did procedural success (overall 69.9%, slope 1.2%/year, p=0.02, R²=51.5%) without a concomitant increase in in-hospital MACE rates (slope 0.1%/year, p=0.7). There was a distinct advantage for successful CTO treatment compared with failed CTO treatment (73.5% vs. 65.1%, p=0.001). The CTO versus non-CTO survival was the same (71.2% vs. 71.4%, p=0.9). Diabetics in the CTO cohort had a lower survival compared with non-diabetics (58.3% vs. 74.3%, p=0.0001). These data represent outcome of PCI for a CTO. The 10-year survival rates for matched non-CTO and the CTO cohorts were similar. Success rates have continued to improve without an accompanying increase in MACE rates. A successfully revascularized CTO confers a significant survival advantage compared with failed revascularization.

Abstract
Neuroblastoma is a cancer of the sympathetic nervous system, accounting for upto 15% of childhood cancer mortality. It can occur in many areas but most of them begin in the abdomen in the adrenal gland and can spread to the bones and other areas. http://en.wikipedia.org/wiki/Neuroblastoma-cite_note-pmid19383347-3. Unfortunately, like other cancers, its causes are still poorly understood. Anaplastic lymphoma kinase (ALK), a membrane associated tyrosine kinase was recently found to be mutated in neuroblastoma. Protein sequence of ALK was retrieved from UniProt and the seven identified mutations were substituted in native sequence to get its mutant proteins. Significant changes were explored in the mutant secondary structures when compared with the native protein. Changes were also observed in the physiochemical properties and it can therefore be inferred that, these changes may be translated in the tertiary structures due to their effects on the folding pattern. Tertiary structure of the protein modeled after refinement and validation was submitted to Protein Model Database (PMDB) and was assigned with the PMDB ID P0077827. RMSD values of the mutant structures were observed deviated from the native structure when compared with probability < 0.05. It was observed that there are a total of 15 Disordered Regions in the protein having a total of 290 Disordered Residues. Protein-ligand interaction analysis was performed to investigate the effects of mutations damaging its interactions and it was observed that the mutations understudy affects its interactions with ATP which ultimately results in causing neuroblastoma. This study was based on the in silico mutation analysis of Seven missense mutations of anaplastic lymphoma kinase which can better explain why missense mutations in ALK protein cause neuroblastoma. Structure and sequence based computations were systematically and comprehensively evaluated applied to the mutants in anaplastic lymphoma kinase and on the basis of our observations a detailed structural explanations have been developed for the measured and predicted impact of these missense substitutions.

Abstract
The present studies found that microalbuminuria is predictive, independent of classical risk factor of cardiovascular diseases and all causes of mortality in diabetes or hypertension patient groups and in the general population. Coronary angiograms for extent of severe CAD (luminal narrowing 50%) in patients with Diabetes Mellitus (DM) and general population were examined. The study comprised 150 patients undergoing coronary angiography at United Hospital Limited, Dhaka, Bangladesh, (M/F 80/70, mean age 57±11 years). Urine albumin excretion was measured in 24 hours urine samples employing immune precipitation technique. Age-gender distribution of coronary risk factors and microalbuminuria were compared between patient with and without coronary artery disease. As many as 70.5% (106) of patient had coronary artery disease and 29.4%(44) had no coronary lesion. Microalbuminuria was detected at 62.9% in patients with CAD and 8.8% in those without coronary artery lesion (p<0.001). The presence of 1 or 2 vessel CAD showed a linear increase between the groups without microalbuminuria. Patients with microalbuminuria have more severe angiographically detected coronary artery disease than those without microalbuminuria, thus a link can be established independent of other risk factors.

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
Day case surgery offers convenience to the patients and cost saving to the healthcare institutes. In this prospective study, the authors reviewed their experience with day case Laparoscopic Cholecystectomy (LC) to determine its outcome in the government healthcare settings of Bangladesh. Selection criteria's for the day case LC were patients with symptomatic cholelithiasis with ASA (American Society of anesthesiologists) grade I or II, the availability of a responsible carer, absence of morbid obesity, low risk for concomitant presence of bile duct stones and domicile within Dhaka and around. Patients were admitted in the post operative ward as day case (DC) in the morning and were discharged on the next morning with a standard analgesia. Two hundred ten patients were admitted for LC as day cases over the last 7 years from October 2003 to October 2010 on the morning operation theatre lists. Five patients later required admission to the inpatient department for conversion to the open procedure. None of the patients was readmitted after discharge. Majority patients were followed up after 1st and 6th week. Two hundred seven patients attended for the follow up at the 1st week and 158 patients were reported for the 6th week. One hundred ninety six patients resumed their normal job or activities after one week. Patient's satisfaction was assessed by questionnaires. Two hundred five patients were either satisfied or very satisfied with the day-case procedure. It appears that for selected groups of patients, day-case LC can be safely done in government healthcare settings of Bangladesh with good patient satisfaction.

Abstract
Hairs are complex structures, making a protective layer and serves different biological functions. TRPS1, a transcription factor is one of the candidate genes causing congenital hypertrichosis, an excessive hair growth at inappropriate body parts. SNPs of TRPS1 were retrieved from dbSNP which were screened by SIFT and PolyPhen servers based on their functional impacts. Out of the screened SNPs, rs181507248 and rs146506752 were predicted as intolerant and damaging by both the servers. The predicted tertiary structure of the native TRPS1 after refinement and validation was successfully submitted to the Protein Model Database and was assigned with PMDB ID PM0077843, as it was previously unpredicted. It was observed through the structure based analysis that, the SNPs rs181507248 and rs146506752 caused significant changes in the secondary and tertiary structures as well as the physiochemical properties of TRPS1 protein. It can thus be concluded that the changed properties due to these single nucleotide polymorphisms effect the interactions of TRPS1 which result in congenital hypertrichosis.

Abstract
Poliovirus causes flaccid paralysis through the destruction of motor neurons in the CNS. Susceptibility to its infection is mainly due to the interaction in between the surface capsid proteins and its receptors on the host cell surface, important for binding, penetration and other necessary events during early infection. Receptor modification is a new approach to treat viral diseases by the modification of target proteins structure. Binding domains are modified in an effective way to make it difficult for the virus to recognize it. In this study, tolerant and intolerant induced mutations in the poliovirus receptor, VP1 and VP2 were identified and substituted in the seed sequence to get the modified versions. Substitutions causing changes in initial folding were short listed and further analyzed for high level folding, physiochemical properties and interactions. Highest RMSD values were observed in between the seed and the mutant K90F (3.265 Å) and Q130W (3.270Å) respectively. The proposed substitutions were found to have low functional impact and thus can be further tested and validated by the experimental researchers. Interactions analyses proved most of the substitutions having decreased affinity for both the VP1 and VP2 and thus are of significant importance against poliovirus. This study will play an important role for bridging computational biology to other fields of applied biology and also will provide an insight to develop resistance against viral diseases. It is also expected that same approach can also be applicable against other viruses like HCV, HIV and other in near future.

Abstract
Hutchinson-Gilford progeria syndrome (HGPS) is caused by de novo dominant point mutations of the genes encoding nuclear lamina proteins, leading towards premature aging. A protein sequence is subjected to mutations in nature which can affect the function and folding pattern of the protein by different ways. Mutations involved in HGPS were identified and were substituted in the seed sequence retrieved from the UniProt database to get the mutated versions. Tertiary structure of the Lamin A protein was previously unpredicted so was performed for all the mutated as well as for the seed protein to analyze the effects of mutations on the protein structure, folding and interactions. All the predicted models were refined and validated through multiple servers for multiple parameters. The validated 3D structure of seed protein was then successfully submitted to the Protein Model Database and was assigned with the PMDB ID PM0077829. All the predicted structures were superimposed with a root mean square deviation value of 7.0 Å and a high Dali Z-score of 1.9. It was observed that mutations affected physiochemical properties as well as instability index and thus is affecting the domains in specific and the whole structure in general. It was further analyzed that HGPS is the result of affected Lamin a protein interactions with other integral and binding proteins in the inner nuclear membrane affecting the link in between the nuclear membrane and the network of the lamina.

Abstract
Squamous cell carcinoma of the oral cavity a type of Oral Cancer in young patients is a very rare occurrence particularly during the first decade of life. Oral cancer is predominantly an aggressive neoplasm of middle-aged people where 96% of the patients are more than 40 years of age and it occurs mainly due to the excessive consumption of tobacco and alcohol. In South-East Asia it has a higher rate of occurrence than the rest of the world, partly due to increased consumption of chewing tobacco and various harmful spices, areca nuts and betel quids. These rare varieties of aggressive neoplasm commonly affect tongue and lip. This report describes a case of squamous cell carcinoma in a 10 year old boy who had an exophytic type of granulomatous lesion with some indurated borders which diffusely involved the left side of the hard palate, alveolar mucosa, left maxillary antrum and aggressively emerged within the left orbit by engulfing the left inferior rectus muscle. The purpose of this case report is to provide information that younger group can suffer from oral squamous cell carcinoma though it is very rare and this younger group would appear to have a biologically more aggressive tumor and they require more complex treatment. The role of more aggressive initial therapy must be considered.
