Abstract
Cardiovascular disease (CVD), exemplified by coronary artery disease (CAD), is a global health concern, escalating in prevalence and burden. The etiology of CAD is intricate, involving different risk factors. CVD remains a significant cause of mortality, driving the need for innovative interventions like percutaneous coronary intervention and vascular stents. These stents aim to minimize restenosis, thrombosis, and neointimal hyperplasia while providing mechanical support. Notably, the challenges of achieving ideal stent characteristics persist. An emerging avenue to address this involves enhancing the mechanical performance of polymeric bioresorbable stents using additive manufacturing techniques And Three-dimensional (3D) printing, encompassing various manufacturing technologies, has transcended its initial concept to become a tangible reality in the medical field. The technology's evolution presents a significant opportunity for pharmaceutical and medical industries, enabling the creation of targeted drugs and swift production of medical implants.

Abstract
Cancer is one of the most prevalent diseases worldwide. The most prevalent condition in women when aberrant cells develop out of control is breast cancer. Breast cancer detection and classification are exceedingly difficult tasks. As a result, several computational techniques, including k-nearest neighbor (KNN), support vector machine (SVM), multilayer perceptron (MLP), decision tree (DT), and genetic algorithms, have been applied in the current computing world for the diagnosis and classification of breast cancer. However, each method has its own limitations to how accurately it can be utilized. A novel convolutional neural network (CNN) model based on the Visual Geometry Group network (VGGNet) was also suggested in this study. The 16 layers in the current VGGNet-16 model lead to overfitting on the training and test data. We, thus, propose the VGGNet-12 model for breast cancer classification. The VGGNet-16 model has the problem of overfitting the breast cancer classification dataset. Based on the overfitting issues in the existing model, this research reduced the number of different layers in the VGGNet-16 model to solve the overfitting problem in this model. Because various models of the VGGNet, such as VGGNet-13 and VGGNet-19, were developed, this study proposed a new version of the VGGNet model, that is, the VGGNet-12 model. The performance of this model is checked using the breast cancer dataset, as compared to the CNN and LeNet models. From the simulation result, it can be seen that the proposed VGGNet-12 model enhances the simulation result as compared to the model used in this study. Overall, the experimental findings indicate that the suggested VGGNet-12 model did well in classifying breast cancer in terms of several characteristics.

Our study is based on MET combination therapy with empagliflozin versus sitagliptin in order to achieve glycemic control. Methods This randomized clinical trial was conducted in the Department of Medicine and Allied of Federal Government Polyclinic Hospital, Islamabad, from January 2022 till June 2022. The ethical approval letter numbered FGPC. 1-1/2022/Ethical Committee was taken before the commencement of the trial. The patients were divided into group A and group B. All patients were given MET 1000mg twice a day. Group A patients were additionally given sitagliptin 50mg twice daily whereas Group B patients were additionally given empagliflozin 10mg once daily. Glycemic control was documented with HbA1c at the start of treatment and after three months of treatment in both groups. A proforma was used to collect data. Analysis of the data was performed using the Statistical Package for the Social Sciences version 17 (SPSS Inc., Chicago, USA). Results A total of 126 patients were included in the study with a mean age of 53.53 ± 6.49. 81.7% were males while 18.3% were females. The mean reduction in HbA1c from baseline in group A was -0.81 ± 0.19% and in group B was -1.13 ± 0.24% with statistically significant p-value (p-value = 0.000). Conclusion Empagliflozin in combination with metformin is more efficacious in maintaining glycemic control as compared to sitagliptin in combination with metformin.

Abstract
Coronary artery disease (CAD) is a cardiovascular disease of the blood vessels that makes vessels, narrow and hardened and difficult to supply blood to the heart. The epidemiology of CAD disease is a common clinical syndrome of a global health priority and the burden is increasing at an alarming rate worldwide. The prevalence of CAD not only increases mortality, morbidity and worsens the patient quality of life but also puts a huge burden on the overall healthcare system. The novel risk factors include: cholesterol level, cigarette smoking, diabetics, obesity, and hypertension, respectively are the causative agents of CAD. Furthermore, the etiology of CAD is also a very complex process and several interrelated etiological factors are involved in the pathogenesis of CAD. The signs and symptoms of CAD appear like angina, heart failure, and dyspnea, myocardial infarction, and arrhythmia, respectively. The management and diagnosis of CAD include different types of medications that are used nowadays for the treatment of this disease. The highlights of the present review focused on stent technology and its useful applications. Finally, we also addressed the benefits of the stent, and its potential complications, effectiveness, indication, and contraindication that play a significant role in the recovery of CAD disease.

Abstract
Background This study aimed to determine the mean improvement in the quality of life (QoL) after laparoscopic cholecystectomy (LC) in patients with symptomatic cholelithiasis. Methodology After obtaining approval from the hospital’s ethical committee, the Gastrointestinal Quality of Life Index (GIQLI) proforma was filled on admission (T0) and at week six (T1) postoperatively. All data were collected, and GIQLI scores were calculated for individual patients. Results In our study, among the 70 patients undergoing LC, 20% (n = 14) were aged 18-30 years and 80% (n = 56) were aged 31-60 years, with the mean ± standard deviation calculated as 41.56 ± 10.13 years. Overall, 44.29% (n = 31) of patients were men and 55.71% (n = 39) were women. GIQLI scores were 94.64 ± 2.24 for pre-treatment and 106.09 ± 2.40 for post-treatment, with a mean change of 11.44 ± 3.29, and a p-value of 0.001, showing a significant difference. Conclusions The mean improvement in QoL after LC in patients with symptomatic cholelithiasis is significantly higher when compared with pretreatment.

Abstract
Introduction Acute appendicitis is one of the leading causes of acute abdominal pain and surgical emergency. Stump appendicitis is a known complication of appendectomy whereby a retained appendiceal tip serves as a nidus for recurrent bouts of inflammation. Nevertheless, full-blown appendicitis of the vermiform appendix after a prior appendectomy remains a diagnostic conundrum. Case presentation A 45-year-old woman presented with a six-month history of right iliac fossa pain. Pertinently, she had undergone a prior open appendectomy twelve years ago. Further investigative workup revealed full-blown appendicitis, which was not attributable to a retained appendiceal stump. A subsequent laparoscopic appendectomy was performed, and the resultant specimen was sent for further evaluation, confirming the diagnosis of recurrent appendicitis. Clinical discussion Acute appendicitis is one of the most common life-threatening abdominal surgical emergencies worldwide, with 300000 appendectomies performed annually in the United States alone. Stump and chronic appendicitis are two separate and exceedingly rare clinical entities that may present simultaneously and develop serious complications unless promptly recognized and appropriately managed. The present paper prompts the clinicians to distinguish amongst the two at the initial surgery in order to thwart further exacerbations. Conclusion While stump appendicitis is a rare but well-characterized complication of a prior appendectomy, full-blown appendicitis of vermiform appendix remains elusive. It is therefore imperative to distinguish between a duplicated and a recurrent appendix at the initial operative procedure to facilitate optimal patient management.

Abstract
Introduction Pancreatic pseudocysts remain a feared complication of acute or chronic pancreatitis and are often characterized by collections of fluids due to underlying damage to the pancreatic ducts, culminating in a walled-off region bereft of an epithelial layer but surrounded by granulation tissue. While fungal infections of pancreatic pseudocysts are rarely encountered, candida albicans remains the most frequently implicated organism. Case presentation A 55-year-old male presented with pain in the left-hypochondriac region, accompanied by non-bilious emesis and nausea. Interestingly, the patient also tested positive for a COVID-19 infection. Investigative workup divulged enhancing pancreatic walls with a radiologic impression consistent with a pancreatic pseudocyst. An ultrasound-guided external drainage was performed; the drainage was conducted unremarkably, with the resultant fluid collection revealing the presence of Candida Glabrata. The patient was commenced on antifungal therapy and continues to do well to date. Discussion Infectious ailments of pancreatic pseudocysts remain a widely known complication of acute pancreatitis. While it is rare, fungal infection is a crucial consideration for patients with pancreatic pseudocysts, especially in the context of a lack of an adequate response to antibiotics, deterioration, comorbidities, and immunocompromised states. Conclusion Rapid identification of the microbe responsible for pancreatic pseudocyst infection is vital for time-sensitive treatment and a more rapid recovery, curbing associated morbidity and mortality. Fungal infections of pancreatic pseudocysts remain a rare but well-characterized complication, culminating in significant morbidity and mortality. Telltale signs include unresponsiveness to antibiotics and worsening clinical symptoms. Rapid identification of the responsible microbe is vital for time-sensitive treatment and a more rapid recovery.

Abstract
Introduction Meckel's diverticulum is a congenital anomaly that is often detected incidentally. When it presents symptomatically, it causes painless gastrointestinal bleeding. Nevertheless, in rare instances, it can cause acute intestinal obstruction, often obscuring the true clinical picture. Case presentation A 31-year-old male presented to the emergency department with a 24-h history of unremitting nausea, biliary emesis, abdominal distension, and absolute constipation. After ruling out the most common etiologies of acute bowel obstruction, radiological imaging was obtained and was suggestive of meckel's diverticulum. Laparoscopic meckel's diverticulectomy was performed, with the subsequent histopathological analysis confirming ectopic gastric tissue. Discussion Meckel's diverticulum occurs consequent to incomplete obliteration of the vitelline or omphalomesenteric duct, which connects the developing intestines to the yolk sac. It is found in roughly 2% of the population, of which only about 4% may become symptomatic due to any number of complications. Specifically, small bowel obstruction (SBO) and diverticulitis secondary to ectopic gastric or pancreatic tissue are the most common presentations of symptomatic MD. Conclusion Although relatively rare in adults, MD should be considered in the list of differentials in patients with intussusception leading to SBO, especially on a background history unremarkable for the most common etiologies causing SBO including post-operative adhesions and hernias.

Abstract
Introduction: Helicobacter pylori (H. pylori) colonization is prevalent all over the world, and it is associated with low socioeconomic status, poor hygiene, and overcrowding. Its eradication is important since it is an etiologic agent for gastritis, peptic ulcer, gastric carcinoma, and mucosa-associated lymphoid tissue lymphoma. Different regimens are available for the eradication of H. pylori and include triple therapy and sequential therapy. Our study aims to compare the efficacy of triple therapy versus sequential therapy in the eradication of H. pylori. Material and methods: This randomized clinical trial was conducted at the Pakistan Institute of Medical Sciences Hospital, Islamabad, from September 2016 to September 2017 after the approval of the institutional review board. A total of 160 patients were enrolled and equally divided into two, group A and group B. A twice-daily dose of amoxicillin 1,000 mg, rabeprazole 20 mg, and clarithromycin 500 mg was given to group A for 10 days, while group B was initially given rabeprazole 20 mg and amoxicillin 1,000 mg two times daily for the first five days (i.e., induction phase), followed by triple therapy that included rabeprazole 20 mg, clarithromycin 500 mg, and metronidazole/tinidazole 500 mg twice daily for the next five days. A negative stool antigen test performed four weeks after the completion of therapy was considered an effective eradication. A proforma was used to collect data that included age, gender, city or province of residence, family income, group (group A or group B), and eradication efficacy. Analysis of the data was performed using the Statistical Package for the Social Sciences version 17 (SPSS Inc., Chicago, USA). Results: A total of 160 patients were included, with mean age and standard deviation of 40.02±24.4 years. The male/female ratio was 1.8:1. Successful eradication of H. pylori achieved in group A was 67.5% (N=54) in comparison to group B, which was 95% (N=76) (p=0.001). Conclusion: Sequential therapy was superior to triple therapy in H. pylori eradication.

Abstract
Background: There are different types of Coronavirus disease (COVID-19) vaccines available presently, and their emergency use has been approved by WHO worldwide on a mass scale. COVID-19 vaccine breakthrough infections have been reported worldwide. In Pakistan, there are limited data on COVID-19 vaccine breakthrough infections and their clinical course, especially in healthcare professionals (HCPs). Our study aims to investigate COVID-19 infections among vaccinated HCPs. Methods: A prospective study was conducted on 425 healthcare professionals. Data collected from healthcare professionals included names, age, gender, number of vaccination doses, COVID-19 infection pre and post-vaccination, the severity of COVID-19 infection (if positive), and co-morbid conditions. Ethical board approval was taken. Statistical Package for Social Sciences (SPSS) version 23 (IBM Corp., Armonk, NY) was used to analyze the data. Results: After complete vaccination, 17.27% acquired COVID-19 infection; 2.47% had COVID-19 infection both pre and post-vaccination. The mean age was 32.46 years (n=71) with a standard deviation of ±9.376. The male to female ratio was 1.53. COVID-19 PCR was positive in 95.77%. During the course of the disease, 4.2% were asymptomatic, 92.95% had mild symptoms, 1.4% were hospitalized, and 1.4% had to be managed in the intensive care unit. None of the HCPs who had received booster doses acquired a COVID-19 infection. Conclusion: It was found that prior COVID-19 infection and vaccination do not confer immunity from infection. However, proper vaccination limits the severity, morbidity, and mortality of COVID-19 infection.

Background
The fact that SAARS-Cov2 virus enters cells through ACE2 receptors and the Renin-Angiotensin-Aldosterone System Inhibitors (RAASi) upregulate the ACE2 receptors, there was speculation that use of RAASi may lead increased cellular entry of the virus. There was a pause for a brief period of the use of RAASi in COVID 19 patients. But clinically the speculation has been found to be incorrect. Different professional societies come up with the assertion to continue to use RAASi. As the hesitancy among the clinicians appears to continue and there is no first hand data regarding the safety of the use of RAASi in Bangladeshi population, the study was undertaken to evaluate the safety of RAASi in COVID 19 patients.
Aims & Methods
This study was a prospective, observational multi-center study to evaluate the outcome of COVID-19 patients receiving RAAS inhibitors. Adult Hypertensive patients (age ≥18 years) with diagnosed COVID-19 confirmed by RT-PCR test who have a history of taking either ACE inhibitor/ARB or any other anti-hypertensive medication. Evaluation of outcome was assessed by rate of hospitalization, requirement of oxygen therapy, requirement of high flow nasal cannula, admission to ICU and mortality between two groups. All statistical analyses were performed using SPSS for Windows, version 20.0 (SPSS Inc., Chicago, IL, USA).
Results
We collected data from 147 Covid-19 positive patients confirmed by RT-PCR. Among them, 117 (79.6%) had a history of taking RAAS inhibitor and 30 had history of taking other antihypertensive medications. Of them, two-third patients had more than 50 years of age and more than half of the patients had overweight or obesity. Other than hypertension they had several comorbidities such as Diabetes Mellitus (45.4%), Ischemic Heart Diseases (35.4%), Asthma or COPD (15%) etc. Rate of hospitalization had no statistical difference between RAAS inhibitor group and other hypertensive group (48.7% vs 46.70% respectively; p-value - 0.841). There was no statistical difference between two groups in terms of requirement of oxygen therapy (p-value - 0.297), High Flow Nasal Cannula (p-value - 0.430), intensive care unit (p-value - 0.194) and death (p-value – 0.383) also. Almost half and one-third of the patients had persistence of symptoms even after 14 days and 28 days respectively. Fatigue, cough, breathlessness, loss of appetite and taste were the most common symptoms among those.
Conclusion
In our study we found that RAAS inhibitor treatment had no adverse effect on the outcome of COVID-19 patients compared with other antihypertensive drugs. Patients may continue receiving ACEIs and ARBs for the treatment of any indication for RAASi without an increased risk of worse outcomes.

Abstract
Abstract Biochemical and physiological parameters, growth, and yield of field crops especially salt sensitive crops like chickpea are affected adversely by salinity in arid to semi-arid regions. To investigate the effect of different salinity levels on growth, biochemical and physiological parameters of chickpea genotypes, a pot experiment following CRD, two factor factorial design, was conducted in the glasshouse at the Institute of Biotechnology and Genetic Engineering, The University of Agriculture, Peshawar, Pakistan. Ten (10) kg of soil was filled in each pot and salinity levels were maintained @ S0= 0 mM NaCl, S1= 50 mM NaCl, S2= 100 mM NaCl and S3= 150 mM by applying NaCl and 5 genotypes of chickpea (KK-2, Bhakkar-2011, Bittle-98, Punjab-2008, and CM-98) were used. At crop maturity, growth parameters, physiological, biochemical, and ionic parameters were measured using standard analysis procedures. Salinity reduced the growth and yield of all genotypes, but the rate of decrease was different among the genotypes tested. From the results, a decrease in K concentration, K/Na ratio, transpiration rate, stomatal conductance, N, and P was observed in all genotypes with the increase in salinity. An increase in salinity level increased the proline content (35.45%), crude protein (42%), H2O2 (19%), lipid peroxidation (62%), carbohydrates (23.22%), and Na+ concentration (137%). The highest level of salinity, 150 mM NaCl has exhibited the highest salinity stress in all parameters. Genotype KK-2 and Bhakkar-11 showed a lower rate of relative decrease in yield (4.5 and 12%), K+/Na+ ratio (23.34 and 11.47%), and K+ concentration (7.9 and 11%), respectively, and the lowest relative increase in Na+ accumulation (20.3 and 0.48%), @ 50 mM salinity compared to control. Genotype KK-2 and Bhakkar-11 proved better @ 50mM salinity. The findings suggest that the critical level of the salinity must be kept in mind and the salt-tolerant genotypes should be cultivated in salt affected soils.

Abstract
Reports abound on Lernaea parasitizing the brood stock, fingerlings, and marketable-sized culturable freshwater fish species in various parts of the world. We investigated seven small-scale aquaculture farms and how the prevailing Lernaea is impacting them. Randomly seven fish farms were selected to determine the prevalence percentage of lernaeid ectoparasites. Relevant information of the fishponds to estimate the various aspects such as effects of water source and quality, feed, stocking density, treatment used, and weight and length of fish, concerned with Lernaea infestation and prevalence was gathered. The results indicated that Catla catla (F. Hamilton, 1822) showed highest prevalence (41.7%) among the seven fish species, whereas Oreochromis niloticus showed zero. Other five fish species Ctenopharyngodon idella, Cirrhinus cirrhosis, Cyprinus carpio, Labeo rohita and Hypophthalmichthys molitrix showed 13.2%, 8.1%, 7.7%, 7.4%, 0.9% prevalence, respectively. In Royal Fish Farm 84.3% lernaeid infestation was observed, while no parasite was observed in the Vicent's Chunnian fish farm. The water source, quality, feed, fertilizers, stocking density, water temperature, and potential treatment options displayed varying tendencies among fish farms and prevalence. Depending on the weight and length, the highest prevalence (56.7%, and 66.7%) was observed in 3501-4000 g and 81-90 cm groups. The infestation rate varied in various fish body parts with the dorsal fin the most vulnerable organ and showed 2.3% overall prevalence (while 18.4% contribution within total 12.6% infestation). Out of 147 infected fish samples, 45 were extensively contaminated by Lernaea spread. In conclusion, our findings confirm that Lernaea could pose a considerable threat to marketable fish, and various treatment options should be educated to the farmers to help mitigate the spread and potential losses. Furthermore, Catla catla is more vulnerable to Lernaea infestation (41.7%), so are the fish species being cultured at higher stocking densities.

Abstract
Left-sided gallbladder (LSGB) is a rare anatomic variation that, while benign in the context of its transposition, is of significant intraoperative importance. Due to its association with other anatomic anomalies involving key structures in the hepatobiliary system, discovering it intraoperatively as opposed to preoperatively suddenly increases the difficulty of a gallbladder procedure. Left-sided gallbladder (LSGB) is a rare anatomic variation that, while benign in the context of its transposition, is of significant intraoperative importance. Although laparoscopic cholecystectomy of a LSGB is safe, it is associated with higher risk of complications such as common bile duct injury. Most cases of a LSGB are diagnosed intraoperatively, and this sudden discovery during the procedure can increase the difficulty, duration, and stress of the procedure due to the other potential anatomic anomalies that LSGB is associated with in the hepatobiliary system.

Abstract
The study was conducted to evaluate the effect of Moringa olifera on the growth and gut health of Tilapia (Oreochromis niloticus). The feed having 30% crude protein was prepared as an experimental diet with 4%, 8% and 10% M. olifera leaf supplementation, respectively. The control diet was devoid of M. olifera leaves. The 10 weeks feeding trial was carried out on 60 fish in aquaria. Fish was fed @ 3% of body weight twice a day. Diet with the high level of inclusion of M. olifera leaves significantly increased the growth rate, Survival Rate (SR), Specific Growth Rate (SGR) and Feed Conversion Efficiency (FCE) in all treatment groups compared to the control group. Similarly, Feed Conversion Ratio (FCR) gradually decreased and found highly-significant. To check the gut health of the Tilapia, random samples were selected and dissected. Nutrient agar was used as culture media to check the growth of bacteria. Pour Plate Method was used for viable colonies count by colony counter. Through staining method, the different bacteria such as Escherichia coli, Salmonella, Shigella and Pseudomonas aeruginosa were identify abundantly in the intestine of control diet fish but less number present in treatment diets groups. These results showed that M. olifera leaves up to 10% of dietary protein can be used for Nile tilapia for significant growth and healthy gut microbiota of fish.

Abstract
Fallopian tube torsion secondary to paraovarian or paratubal cyst is a rare gynecological cause of acute abdomen. The condition has no distinctive signs and symptoms. There are no characteristic features on radiological imaging, making preoperative diagnosis very difficult. Paraovarian cysts that are less than 4 cm in size are mostly asymptomatic and found incidentally during a pelvic examination or radiological imaging. It seldom leads to any complications like fallopian tube torsion hemorrhage or rupture. We report a case of an adolescent girl, who presented with severe abdominal pain. Transabdominal ultrasound was suggestive of a cystic structure less than 4 cm in size in the left adnexa. Doppler ultrasound showed normal blood flow to both ovaries. Diagnostic laparoscopy was performed, which revealed a twisted left-sided fallopian tube with a fimbrial paraovarian cyst. Detorsion and paraovarian cystectomy was performed. Although paraovarian cysts are mostly asymptomatic, those arising near the fimbrial end can lead to torsion of the fallopian tube, therefore it should always be considered a possible cause of acute abdomen in adolescent girls with adnexal cysts on ultrasound. Timely surgical intervention can prevent complications such as fallopian tube necrosis, gangrene, removal of the tube, and its long-term implications especially in women of the reproductive age group.

Abstract
A novel coronavirus (2019-nCoV) is an acute life-threatening disease, emerged in China, which imposed a potentially immense toll in terms of public health emergency due to high infection rate and has a devastating economic impact that attracts the world's attention. After that, on January 30, 2020, it was officially declared as a global pandemic by World Health Organization (WHO). The International Committee on Taxonomy of Viruses (ICTV) recognized it as a Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) and the disease named Coronavirus Disease-19 (COVID-19). Several studies have been ameliorated the active role of COVID-19 transmission, etiology, pathogenicity, and mortality rate as serious impact on human life. The symptoms of this disease may include fever, fatigue, cough and some peoples are severely prone to gastrointestinal infection. The elderly and seriously affected peoples are likely concerned with serious outcomes. In this review, we mainly aimed to provide a benchmark summary of the silent characteristics and findings of some candidates for antiviral drugs and immunotherapies such as plasma therapy, cytokine therapy, antibodies, intravenous immunoglobulin, and pharmaceutical health concerns that are related to this disease.

Abstract
Breast sarcomas remain a rare malignancy and are noted to portend a particularly dismal prognosis. Due to their high rates of recurrence, a surgical excision with negative margins remains the preferred treatment modality. Nevertheless, their sparse prevalence often poses a diagnostic conundrum. In this report, we chronicle the case of a 46-year-old female with a recurrent breast sarcoma that was treated with wide local excision. Interestingly, no flap reconstruction, skin graft surgery, or primary wound closure was performed, and the resultant wound was left to heal by secondary intention. The patient continues to do well to date, with no postoperative complications.

Abstract
Background Breast cancer remains the most common cause of cancer related mortality amongst women in Pakistan. Postoperative complications can demoralize the patients and potentially delay adjuvant treatment, leading to adverse outcomes. The overarching aim of the study is to delineate the early postoperative outcomes of breast cancer surgery in Pakistan. Materials and Methods A retrospective study involving patients who underwent breast cancer surgery from June 2016 to December 2019 was conducted. Perioperative morbidities (30 days) were evaluated and documented. The results obtained were analyzed using the SPSS 23 software (IBM Corporation, Armonk, NY). Results A total of 94 patients were included in the study, with the mean age of 50±12.8 years. Breast conserving surgery was performed in 32% (n=31) of the patients, while the remaining 68% (n=63) underwent modified radical mastectomy. The most common complications were seroma formation, flap necrosis and hematoma formation and were observed in 5.3% (n=5), 4.3% (n=4) and 3.2% (n=3) of the patients, respectively. Conclusion Early postoperative complications can delay the commencement of adjuvant systemic therapy required for further management of breast cancer. These complications elicit equally grave consequences for patients undergoing breast conserving surgery and modified radical mastectomy.

Abstract
Introduction Soft tissue sarcomas remain an exceedingly rare malignancy. While soft tissue sarcomas boast a high mortality rate, their characteristics and behavior patterns are poorly understood. This study aims to evaluate the various aspects that pertain to soft tissue sarcomas, including their histology, tumor characteristics, survival rates, and therapeutic modalities. Methods A retrospective study analyzing the data from 19 patients presenting over four years with a histologically confirmed diagnosis of soft tissue sarcomas was conducted. The patients were studied for various parameters, including tumor site and the particular pathological subtypes. The data obtained were analyzed using the SPSS 23.0 statistical software (IBM Corporation, Armonk, NY), and the results were then tabulated. Results A total of 19 patients with a confirmed diagnosis of a soft tissue sarcoma were included in the study. The mean age of the patients included was 45.32 ± 16.88 years. Wide local excision was the most common surgical procedure employed for the resection of these tumors. Within the cohort, the mortality rate was noted to hover at 10.52%. Gastrointestinal stromal tumors were observed in 21% of the patients and were therefore the most common histological subtype. Of the patients included, 42.10% required blood transfusion during the perioperative time. Most of the tumors were noted to be intermediate grade, with high-grade tumors observed in 26.3% of the cases. Conclusion Soft tissue sarcomas remain a rare but potent cause of death in developing countries. The diversity of the tissues that they afflict renders their prompt detection a diagnostic challenge. A meticulous exploration of the various characteristics honed by soft tissue sarcomas, such as the particular histological subtype and the associated mortality rates, can better elucidate the prognosis and the eventual disease outcomes.

Abstract
Background Affections of the gallbladder remain exceedingly ubiquitous and often warrant surgical intervention. The histopathological patterns represent a spectrum, ranging from cholecystitis to gallbladder carcinoma. The present study aims to delineate the occurrence of various gallbladder histopathologies in a tertiary care hospital in Pakistan. Methods A retrospective study was conducted at Maroof International Hospital, Islamabad, Pakistan. Histopathological records of 442 gallbladder specimens obtained from cholecystectomy were analysed. The prevalence of various histopathological outcomes was assessed. The data were eventually analysed using the SPSS 23.0 software (Armonk, NY: IBM Corp.). Thereafter, the distribution of various gallbladder histopathologies was tabulated across gender. Results Of the 442 patients included, 330 were females and 112 were males, with the mean age hovering at 45.77±14.65 years. The most common histopathological findings were chronic cholecystitis and cholesterolosis, observed in 78.6% and 32.8% of the patients, respectively. While only one case of gallbladder adenocarcinoma was observed, multiple specimens divulged premalignant lesions including reactive atypia and intestinal metaplasia. Conclusions Diseases of the gallbladder often mandate prompt surgical intervention. Of these, chronic cholecystitis, which is an established risk factor for gallbladder carcinoma, is exceedingly common. The employment of histopathological techniques remains imperative in the detection of premalignant and malignant lesions that might otherwise evade macroscopic detection and thus progress to adenocarcinoma.

Abstract
Ovarian tumors occurring secondarily to metastatic colorectal carcinoma remain a rare occurrence. Since ovarian tumors remain predominantly asymptomatic in the initial stages, they are often diagnosed incidentally. The vague, non-specific symptoms elicited by a secondary ovarian carcinoma, coupled with a histopathology remarkably similar to that evoked by primary ovarian tumors, render its ascertainment a diagnostic challenge. We hereby delineate an interesting case of a metachronous ovarian adenocarcinoma in a 19-year-old patient with a prior medical history significant for colorectal carcinoma treated with hemicolectomy. Subsequent diagnostic workup divulged a mass in her left adnexal region, which was ultimately diagnosed as a metastatic colon adenocarcinoma to the ovary. Unfortunately, the patient succumbed to the aggressive malignancy and did not survive. We therefore aim to accentuate the diagnostic and therapeutic dilemmas fomented by ovarian adenocarcinomas that arise secondarily to primary colorectal cancers.

Abstract
Ovarian carcinomas remain a cause of soaring mortality in the general population. Due to their anatomical location in the pelvis, malignant ovarian transformations often evade early detection, reaching astronomical proportions before eliciting clinically obvious symptoms. Epithelial ovarian carcinomas encompass a concoction of tumours derived from the ovarian surface epithelium, and are further subdivided into several subtypes ascertained primarily through histopathological workup. Of these subtypes, endometrioid ovarian carcinoma is noted to be a particularly well-differentiated tumour that often presents early in the disease course. Contrarily, advanced-stage tumours manifest a vague constellation of symptoms, such as abdominal distension and bloating, resulting in dilatory tumour detection. We hereby delineate an interesting case of a high-grade ovarian endometrioid carcinoma that, due to its vague presenting symptoms and a concomitant history of amenorrhea, was erroneously regarded as pregnancy. Subsequent diagnostic workup divulged a bilateral endometrioid ovarian carcinoma with associated serosal involvement and extensive lymph-vascular invasion.

Abstract
Liposarcomas are exceedingly rare entities that evoke malignant transformation of connective tissue and fat cells. These tumours occur throughout the soft tissues of the body, afflicting a myriad of regions. In the adult population, liposarcomas represent the most prevalent subtype of sarcomas, and often arise de novo. Retroperitoneal liposarcomas (RLS) are a ubiquitous subset of sarcomas that, due to their deep location in the hollow abdomen, can grow to astronomical proportions before manifesting any noticeable symptoms; a prompt diagnosis of RLS is therefore often rendered dilatory. We hereby delineate the case of a 43-year-old woman who presented with vague left hemiabdominal distention and discomfort. A subsequent computed tomography scan divulged a giant retroperitoneal growth impaling on and thus displacing the pancreas. A compartmental, en bloc resection was performed, with subsequent histopathology of the excised specimen revealing a well-differentiated liposarcoma. The surgical intervention was curative and led to an uneventful recovery. This paper highlights the pertinence of surgical management as an appropriate treatment modality for a complete resection of RLS.

Abstract
The purpose of this study was to investigate magnitude, pattern and involvement of previously unheralded coronary artery disease in patients suffering from clinically significant peripheral artery disease of lower limbs. This cross sectional study was carried out in National Institute of Cardiovascular Diseases, Dhaka, Bangladesh from January 2014 to February 2015. Total 58 patients with clinically diagnosed peripheral arterial disease of lower limb undergoing angiographic evaluation. Selective CAG in addition to peripheral arteriography was performed in all the study population as per ACC/AHA guidelines for CAG (class IIa recommendation).In this study, it was documented that the proportion of coronary arterial disease was highest in LAD (63.9%) followed by LCX (55.6%), RCA (52.8%), and lowest LM (11.1%) in lesion with aorto-iliac segment. But the proportion of coronary arterial disease was highest in LCX (41.9%) followed by LAD (38.7%), RCA (35.5%), and lowest LM (12.9%) in lesion with femero-popliteal blood vessels. Similarly, the proportion of coronary arterial disease was highest in LCX (36.4%) followed by RCA (27.3%) and equal percentage in LAD and lowest in LM (9.1%) in tibioperoneal segment. Patients of peripheral arterial disease (PAD) having no symptoms of coronary artery disease (CAD) are more likely to have severe coronary artery involvement. Coronary angiogram should be done in patient with PAD to detect previously undetected CAD and pattern of PAD reflects the severity and involvement of coronary arteries.

Abstract
OBJECTIVE Anterior cruciate ligament (ACL) degeneration leads to knee instability and favors osteoarthritis (OA) progression. During ageing the growth factor sensitivity of ligaments changes but nothing is known about BMP2-signalling and -sensitivity in degenerated ACLs. This study addressed the question whether a dysregulated BMP2 signalling might contribute to age- and OA-dependent ACL degeneration. METHOD ACL samples from patients with/without OA of different ages (<60 and ≥60 years, males, females) were graded histopathologically (n = 45). After stimulation of cultured ACL fibroblasts with 5 nM BMP2 for different time points, phosphorylation of SMAD1/5/8 and gene expression of crucial BMP2 signalling proteins, ligamentogenic and chondrogenic transcription factors, scleraxis (SCX) and SOX9, were analyzed. RESULTS ACL samples displayed different grades of degeneration, often associated with synovitis and calcium deposits. Degeneration correlated significantly with synovitis. ACL fibroblasts expressed BMP type I receptors ALK3 and ALK6 and the BMP type II receptor BMPRII. Donors could be divided into "responders" and "non responders" since their BMP2 mediated SMAD1/5/8 phosphorylation level differed. Basal ID1 expression was lower in cells derived from OA compared with non-OA patients and BMP2 led to an ID1 induction in both. Irrespective of BMP2 stimulation, the donor age significantly influenced the expression profile of BMP6 and SCX but not BMP signalling. The BMP2-mediated SMAD6 expression differed between OA and healthy ACL fibroblasts. CONCLUSION Our data indicate that the expression level of BMP2/SMAD target genes such as ID1 and SMAD6 was reduced in ACL fibroblasts derived from OA compared with non OA patients.

Abstract
Age-related peculiarities of the adaptation of the hypothalamo-hypophyseo-adrenal system (HHAS) to the effect of heterotypic stress was studied experimentally in the context of stress-associated behavioral reactions. Young (3 month old), mature (6 month old) and aging (12 month old) Sprague Dawley rats (total number of animals equal to 36) were exposed to chronic heterotypic stressors for 7 days with the subsequent testing of their behavioral responses. Histological changes were studied in the hypothalamus, pituitary and adrenal glands as compared to age-matched control; immunohistochemical reactions were performed to demonstrate CRF, ACTH, ED1, PCNA and caspase-3 with subsequent image analysis. In the aging organism, as compared to young and mature animals, the degree of HHAS activation indicated the dissociation in its central part and adaptive desensitization prevention, typical to young and mature animals. Specifically, in the aging animals exposed to stress, high hypothalamic CRF expression was noted in association with relatively low hypophyseal ACTH expression and high level of adrenal activity. Reduced HHAS plasticity in the aging animals as compared to that in the other age groups, corresponded to their behavioral changes, demonstrating the reduced capacity of the aging organism to adapt to the exposure of unpredictably changing stressors.

Abstract
Left Ventricular (LV) noncompaction is a rare disorder of endomyocardial morphogenesis. It has got a high mortality rate. It is frequently missed during diagnosis because of lack of suspicion and lack of definite diagnostic criteria. We are reporting a case of LV noncompaction in a Bangladeshi patient. Patient presented to us with history of repeated syncope. She had family history of sudden cardiac death. Clinically, there had a systolic murmur in left parasternal area. Her ECG showed different arrhythmia like atrial fibrillation, sinus bradycardia and Ventricular tachycardia. Her echocardiography showed features consistent with 'left ventricular noncompaction'. This is the first case report of this type in a Bangladeshi patient.

Abstract
Malaria is a major public health concern, and malarial parasites have developed resistance against the commonly available drugs. So now a days it is a major concern to find out a new target for drug therapy. Plasmodium falciparum 3D7, one of the strains of plasmodium species also lacks in a functional tricarboxylic acid cycle and solely dependent on glycolysis for its energy supply like other plasmodium species. Although enzymes of malarial parasite have been considered as potential antimalarial drug targets, a little is known about their structural biology. The tertiary structure of triose phosphate isomerase of P. falciparum 3D7 was determined by means of homology modeling through multiple alignment followed by intensive optimization and validation. The modeling was done by Swiss-Model Workspace. The obtained model was verified with the structure validation programs such as, PROCHECK, Verify3D, and QMEAN for reliability. The verify3D value of 0.69 indicates that the environment profile of the model is good. A self-optimized prediction method with alignment or SOPMA is employed for calculation of the secondary structural features of triose phosphate isomerase. The secondary structure indicates that the predicted 3D structure of triosephosphate isomerase of P. falciparum 3D7 contains 48.37% α-helix, 29.27% random coil, and 16.67% extended strand. Active site determination through CASTp suggests that this protein can be utilized as a potential drug target. However, these will further be tested by wet lab studies for a targeted vaccine design against P. falciparum 3D7.

Abstract
UNLABELLED Folliculo-stellate cells are known as S-100 protein immunopositive cells of the anterior lobe of pituitary gland which are not secreting hormones and are presumed to be organ specific stem cells of the adenohypophys. Their role in adaptation of the body to stress remains unclear. AIM To evaluate dynamics of folliculo-stellate and hormone-producing cells in rats of different age in chronic stress exposure. MATERIALS AND METHODS Sprague-Dawley rats aged 1, 3, 6 and 12 months were exposed to chronic immersion immobilization stress. Histological section of the pituitary glands were stained immunohistochemically with subsequent image analysis. RESULTS In control rats S-100 protein-immunopositive cells increased in number with age and negatively correlated with the number of ACTH-positive cells. In experimental animals aged 1 and 3 months volume density of S-100 protein-immunoreactive cells significantly decreased and negatively correlated with ACTH-positive cells, while in 6 month old rats it was only slightly decreased and in 12 months old animals showed tendency to increase. CONCLUSIONS Results of the study demonstrating capacity of the folliculo-stellate cells to contribute to the plasticity of the hypothalamo-hypophyseo-adrenal axis in chronic stress exposure at different age.

Abstract
Fifty male Japanese quails of 40 days of age were divided into five equal groups viz. A, B, C, D, and E. Drinking water supplemented with sodium hypochlorite at dose level of 0, 25, 50, 200, and 400 mg chlorine/L, respectively was offered for 6 weeks. At the end of week 6 when no clinical signs of toxicity of sodium hypochlorite appeared, the birds in groups B and C were shifted to 100 mg chlorine/L drinking water, and this level was increased fourfold (400, 1600, 6400 mg chlorine/L drinking water) every week, till i.e., 10th week (70 day). Afterwards all the birds were killed. Depression and anorexia were prominent clinical signs observed. Reduction in feed intake, body weight, and hematological parameters appeared in a dose-dependant manner. Decreased serum total proteins and weights of liver, heart, and kidneys were recorded in birds receiving high levels of sodium hypochlorite. Intoxicated birds were emaciated. Decreased weight and volume of the testes were observed in birds receiving high levels of sodium hypochlorite. However, birds receiving 400 mg chlorine (group E) had smaller but functional testes. Birds receiving higher level of chlorine (groups B and C) had decreased weight and volume of testes, atrophied seminiferous tubules, and arrested spermatogenesis. It was concluded that sodium hypochlorite at high levels, that is, 6400 mg/L in drinking water is toxic to the quails; therefore, it should be used with caution in poultry farming as drinking water disinfectant.

Abstract
Motivated by applications in systems biology, a probabilistic framework based on Markov processes is proposed to represent intracellular processes. The formal relationships between different stochastic models referred to in the systems biology literature are reviewed. As part of this review, a novel derivation of the differential Chapman-Kolmogorov equation for a general multidimensional Markov process made up of both continuous and jump processes, is presented. First, the definition of a time-derivative for a probability density is focused, but placing no restrictions on the probability distribution, in particular, it is not assumed to be to be confined to a region that has a surface (on which the probability is zero). In this derivation, the master equation gives the jump part of the Markov process and the Fokker-Planck equation gives the continuous part. As a result, a 'family tree' for stochastic models in systems biology is sketched, providing explicit derivations of their formal relationship and clarifying assumptions involved.

Abstract
Genes of the human monocytic leukemia zinc-finger protein MOZ (HUGO symbol, MYST3) and its paralog MORF (MYST4) are rearranged in chromosome translocations associated with acute myeloid leukemia and/or benign uterine leiomyomata. Both proteins have intrinsic histone acetyltransferase activity and are components of quartet complexes with noncatalytic subunits containing the bromodomain, plant homeodomain-linked (PHD) finger and proline-tryptophan-tryptophan-proline (PWWP)-containing domain, three types of structural modules characteristic of chromatin regulators. Although leukemia-derived fusion proteins such as MOZ-TIF2 promote self-renewal of leukemic stem cells, recent studies indicate that murine MOZ and MORF are important for proper development of hematopoietic and neurogenic progenitors, respectively, thereby highlighting the importance of epigenetic integrity in safeguarding stem cell identity.
