Abstract
In the present work, 2-imino-1,3-thiazolines featuring highly fluorinated fragments were synthesized through a straightforward cyclization of diversely substituted thioureas with 2-bromo-1-(4-fluorophenyl)ethan-1-one. The target compounds were obtained in good yields, and structures were established by FTIR and 1H- and 13C NMR spectroscopic methods. The in vitro biological assay revealed that all the compounds significantly obstruct the α-glucosidase. Compound 6d (3-fluoro-N-(3-(2-fluorophenyl)-4-(4-fluorophenyl)thiazol-2(3H)-ylidene)benzamide) showed the highest antidiabetic potential with an IC50 value of 1.47 ± 0.05 μM. In addition, computational analysis revealed the binding energy of -11.1 kcal/mol for 6d which was lower than the positive standard, acarbose (-7.9 kcal/mol). Several intermolecular interactions between the active site residues and 6d highlight the significance of 2-imino-1,3-thiazoline core in attaining the potent efficacy and making these compounds a valuable pharmacophore in drug discovery.

Abstract
Dwarfism is a medical term used to describe individuals with a height-vertex measurement that falls below two standard deviations (-2SD) or the third percentile for their gender and age. Normal development of growth is a complicated dynamic procedure that depends upon the coordination of different aspects involving diet, genetics, and biological aspects like hormones in equilibrium. Any severe or acute pathologic procedure may disturb the individual's normal rate of growth. In this research, we examined four (A-D) Pakistani consanguineous families that exhibited syndromic dwarfism, which was inherited in an autosomal recessive pattern. The genomic DNA of each family member was extracted by using phenol-chloroform and Kit methods. Whole Exome Sequencing (WES) of affected family members (IV-11, III-5, IV-4 and III-13) from each group was performed at the Department of Medical Genetics, University of Antwerp, Belgium. After filtering the exome data, the mutations in PPM1F, FGFR3, ERCC2, and PCNT genes were determined by Sanger sequencing of each gene by using specific primers. Afterward, FGFR3 was found to be a suitable drug target among all the mutations to treat achondroplasia also known as disproportionate dwarfism. BioSolveIT softwares were used to discover the lead active inhibitory molecule against FGFR3. This research will not only provide short knowledge to the concerned pediatricians, researchers, and family physicians for the preliminary assessment and management of the disorder but also provide a lead inhibitor for the treatment of disproportionate dwarfism.Communicated by Ramaswamy H.

Abstract
Ovarian cancer is the fifth leading cause of mortality and the most lethal gynecologic malignancy among females. It may arise from atypical borderline tumors (Type I) or serous tubal intraepithelial carcinoma (Type II). The diagnosis of cancer at its early stages is difficult because of non-specific symptoms, most patients are diagnosed at the advanced stage. Several drugs and therapeutic strategies are available to treat ovarian cancer such as surgery, chemotherapy, neoadjuvant therapy, and maintenance therapy. However, the cancer cells have developed resistance to a number of available therapies causing treatment failure. This emerging chemoresistance in ovarian cancer cells is becoming an obstacle due to alterations in multiple cellular processes. These processes involve altered drug target response, drug pumps, detoxification systems, lower sensitivity to apoptosis, and altered proliferation, and are responsible for developing resistance to anticancer medicines. Various research reports have evidenced that these altered processes might play a role in the emergence of resistance. This review addresses the recent advances in understanding the underlying mechanisms of ovarian cancer resistance and covers sophisticated alternative pathways to overcome these resistance mechanisms in patients.

Abstract
The coronavirus, a subfamily of the coronavirinae family, is an RNA virus with over 40 variations that can infect humans, non-human mammals and birds. There are seven types of human coronaviruses, including SARS-CoV-2, is responsible for the recent COVID-19 pandemic. The current study is focused on the identification of drug molecules for the treatment of COVID-19 by targeting human proteases like transmembrane serine protease 2 (TMPRSS2), furin, cathepsin B, and a nuclear receptor named farnesoid X receptor (FXR). TMPRSS2 and furin help in cleaving the spike protein of the SARS-CoV-2 virus, while cathepsin B plays a critical role in the entry and pathogenesis. FXR, on the other hand, regulates the expression of ACE2, and its inhibition can reduce SARS-CoV-2 infection. By inhibiting these four protein targets with non-toxic inhibitors, the entry of the infectious agent into host cells and its pathogenesis can be obstructed. We have used the BioSolveIT suite for pharmacophore-based computational drug designing. A total of 1611 ligands from the ligand library were docked with the target proteins to obtain potent inhibitors on the basis of pharmacophore. Following the ADMET analysis and protein ligand interactions, potent and druggable inhibitors of the target proteins were obtained. Additionally, toxic substructures and the less toxic route of administration of the most potent inhibitors in rodents were also determined computationally. Compounds namely N-(diaminomethylene)-2-((3-((1R,3R)-3-(2-(methoxy(methyl)amino)-2-oxoethyl)cyclopentyl)propyl)amino)-2-oxoethan-1-aminium (26), (1R,3R)-3-(((2-ammonioethyl)ammonio)methyl)-1-((4-propyl-1H-imidazol-2-yl)methyl)piperidin-1-ium (29) and (1R,3R)-3-(((2-ammonioethyl)ammonio)methyl)-1-((1-propyl-1H-pyrazol-4-yl)methyl)piperidin-1-ium (30) were found as the potent inhibitors of TMPRSS2, whereas, 1-(1-(1-(1H-tetrazol-1-yl)cyclopropane-1‑carbonyl)piperidin-4-yl)azepan-2-one (6), (2R)-4-methyl-1-oxo-1-((7R,11S)-4-oxo-6,7,8,9,10,11-hexahydro-4H-7,11-methanopyrido[1,2-a]azocin-9-yl)pentan-2-aminium (12), 4-((1-(3-(3,5-dimethylisoxazol-4-yl)propanoyl)piperidin-4-yl)methyl)morpholin-4-ium (13), 1-(4,6-dimethylpyrimidin-2-yl)-N-(3-oxocyclohex-1-en-1-yl)piperidine-4-carboxamide (14), 1-(4-(1,5-dimethyl-1H-1,2,4-triazol-3-yl)piperidin-1-yl)-3-(3,5-dimethylisoxazol-4-yl)propan-1-one (25) and N,N-dimethyl-4-oxo-4-((1S,5R)-8-oxo-5,6-dihydro-1H-1,5-methanopyrido[1,2-a][1,5]diazocin-3(2H,4H,8H)-yl)butanamide (31) inhibited the FXR preferentially. In case of cathepsin B, N-((5-benzoylthiophen-2-yl)methyl)-2-hydrazineyl-2-oxoacetamide (2) and N-([2,2'-bifuran]-5-ylmethyl)-2-hydrazineyl-2-oxoacetamide (7) were identified as the most druggable inhibitors whereas 1-amino-2,7-diethyl-3,8-dioxo-6-(p-tolyl)-2,3,7,8-tetrahydro-2,7-naphthyridine-4‑carbonitrile (5) and (R)-6-amino-2-(2,3-dihydroxypropyl)-1H-benzo[de]isoquinoline-1,3(2H)-dione (20) were active against furin.

Abstract
Yellow fever is a flavivirus having plus-sensed RNA which encodes a single polyprotein. Host proteases cut this polyprotein into seven nonstructural proteins including a vital NS3 protein. The present study aims to identify the most effective inhibitor against the helicase (NS3) using different advanced ligand and structure-based computational studies. A set of 300 ligands was selected against helicase by chemical structural similarity model, which are similar to S-adenosyl-l-cysteine using infiniSee. This tool screens billions of compounds through a similarity search from in-built chemical spaces (CHEMriya, Galaxi, KnowledgeSpace and REALSpace). The pharmacophore was designed from ligands in the library that showed same features. According to the sequence of ligands, six compounds (29, 87, 99, 116, 148, and 208) were taken for pharmacophore designing against helicase protein. Subsequently, compounds from the library which showed the best pharmacophore shared-features were docked using FlexX functionality of SeeSAR and their optibrium properties were analyzed. Afterward, their ADME was improved by replacing the unfavorable fragments, which resulted in the generation of new compounds. The selected best compounds (301, 302, 303 and 304) were docked using SeeSAR and their pharmacokinetics and toxicological properties were evaluated using SwissADME. The optimal inhibitor for yellow fever helicase was 2-amino-N-(4-(dimethylamino)thiazol-2-yl)-4-methyloxazole-5-carboxamide (302), which exhibits promising potential for drug development.Communicated by Ramaswamy H.

Abstract
This research has been designed to analyze the risk factors of major eye diseases and the genetic alterations contributing to the manifestation of such disease. For this purpose, data was collected from 256 patients diagnosed by an ophthalmologist by using a specialized questionnaire. Blood samples were collected from 100 patients to perform a genetic investigation of cataracts. Whole genomic DNA was extracted from blood samples via the phenol-chloroform method. The purified DNA was used as the template for the amplification of about 400 bp fragments amplifying exons 1 and 2 of the CRYAA gene. The statistical analysis showed that 68% of individuals were blind due to cataracts. During molecular analysis, nucleotide sequences obtained have resulted in one silent mutation that occured at 20 positions in exon 2. It was replacing A>G which in turn substitutes the Lysine at position 70 for Arginine. It was interpreted by statistical analysis that this mutation did not result in a significant change in the CRYAA gene. In addition, protein analysis showed no significant changes in the structure of normal and mutated genes. At last, it is concluded that environmental risk factors play a major role in the studied diseases as compared to genetic factors. It is recommended to extend the study to a larger population to study all exons of the CRYAA gene as well as develop better estimates of the magnitude of the problems of visual loss and eye diseases in the Pakistani population.

Abstract
Non-small cell lung cancer (NSCLC) is the most common form of lung cancer. Despite the existence of various therapeutic options, NSCLC is still a major health concern due to its aggressive nature and high mutation rate. Consequently, HER3 has been selected as a target protein along with EGFR because of its limited tyrosine kinase activity and ability to activate PI3/AKT pathway responsible for therapy failure. We herein used a BioSolveIT suite to identify potent inhibitors of EGFR and HER3. The schematic process involves screening of databases for constructing compound library comprising of 903 synthetic compounds (602 for EGFR and 301 for HER3) followed by pharmacophore modeling. The best docked poses of compounds with the druggable binding site of respective proteins were selected according to pharmacophore designed by SeeSAR version 12.1.0. Subsequently, preclinical analysis was performed via an online server SwissADME and potent inhibitors were selected. Compound 4k and 4m were the most potent inhibitors of EGFR while 7x effectively inhibited the binding site of HER3. The binding energies of 4k, 4m, and 7x were -7.7, -6.3 and -5.7 kcal/mol, respectively. Collectively, 4k, 4m and 7x showed favorable interactions with the most druggable binding sites of their respective proteins. Finally, in silico pre-clinical testing by SwissADME validated the non-toxic nature of compounds 4k, 4m and 7x providing a promising treatment option for chemoresistant NSCLC.

Abstract
Alkaptonuria (AKU) is a rare genetic autosomal recessive disorder characterized by elevated serum levels of homogentisic acid (HGA). In this disease, tyrosine metabolism is interrupted because of the alterations in homogentisate dioxygenase (HGD) gene. The patient suffers from ochronosis, fractures, and tendon ruptures. To date, no medicine has been approved for the treatment of AKU. However, physiotherapy and strong painkillers are administered to help mitigate the condition. Recently, nitisinone, an FDA-approved drug for type 1 tyrosinemia, has been given to AKU patients in some countries and has shown encouraging results in reducing the disease progression. However, this drug is not the targeted treatment for AKU, and causes keratopathy. Therefore, the foremost aim of this study is the identification of potent and druggable inhibitors of AKU with no or minimal side effects by targeting 4-hydroxyphenylpyruvate dioxygenase. To achieve our goal, we have performed computational modelling using BioSolveIT suit. The library of ligands for molecular docking was acquired by fragment replacement of reference molecules by ReCore. Subsequently, the hits were screened on the basis of estimated affinities, and their pharmacokinetic properties were evaluated using SwissADME. Afterward, the interactions between target and ligands were investigated using Discovery Studio. Ultimately, compounds c and f were identified as potent inhibitors of 4-hydroxyphenylpyruvate dioxygenase.

Abstract
Polycystic ovary syndrome (PCOS) is a highly widespread disorder caused by a disturbed endocrine system. The Rotterdam criteria have classified 4 phenotypes of PCOS. This syndrome has multifactorial pathophysiology triggered by a disturbed neuroendocrine system, which further produces abnormal levels of luteinizing hormone, follicle-stimulating hormone, androgen, estrogen, and progesterone, leading towards the risk of metabolic and reproductive diseases. PCOS is associated with an increased risk of developing health problems like hyperinsulinemia, diabetes mellitus, hypertension, cardiovascular disorders, dyslipidaemia, endometrial hyperplasia, anxiety and depression. These days, PCOS has become a scientific issue due to complex aetiology with multi- complex physiology. Due to the unavailability of specific medicines, there is no cure for PCOS; however, certain symptoms could be treated. The scientific community is actively looking for various treatment options too. In this context, the current review summarizes the challenges, consequences and various treatment options for PCOS. Various literature reports provide evidence that PCOS can be identified in early infancy, adolescents and women at the menopausal stage. Most commonly, PCOS is caused by multifactorial agents, including genetics and negative lifestyle. Metabolic consequences from obesity, insulin resistance, and vascular disorder have increased the rate of PCOS. This study also highlights psychological morbidity in PCOS women that have an adverse effect on health-related quality of life (HRQoL). PCOS symptoms can be treated using different strategies, including oral contraceptive drugs, surgical treatment (laparoscopic ovarian drilling (LOD), assisted reproductive techniques (ART), and Chinese acupuncture treatment.

Abstract
BACKGROUND Monkeypox virus is an enveloped DNA virus that belongs to Poxviridae family. The virus is transmitted from rodents to primates via infected body fluids, skin lesions, and respiratory droplets. After being infected with virus, the patients experience fever, myalgia, maculopapular rash, and fluid-filled blisters. It is necessary to differentiate monkeypox virus from other poxviruses during diagnosis which can be appropriately envisioned via DNA analysis from swab samples. During small outbreaks, the virus is treated with therapies administered in other orthopoxviruses infections and does not have its own specific therapy and vaccine. Consequently, in this article, two potential peptides have been designed. METHODS For the purpose of designing a vaccine, protein sequences were retrieved followed by the prediction of B- and T-cell epitopes. Afterward, vaccine structures were predicted which were docked with toll-like receptors. The docked complexes were analyzed with iMODS. Moreover, vaccine constructs nucleotide sequences were optimized and expressed in silico. RESULTS COP-B7R vaccine construct (V1) has antigenicity score of 0.5400, instability index of 29.33, z-score of - 2.11-, and 42.11% GC content whereas COP-A44L vaccine construct (V2) has an antigenicity score of 0.7784, instability index of 23.33, z-score of - 0.61, and 48.63% GC content. It was also observed that COP-A44L can be expressed as a soluble protein in Escherichia coli as compared to COP-B7R which requires a different expression system. CONCLUSION The obtained results revealed that both vaccine constructs show satisfactory outcomes after in silico investigation and have significant potential to prevent the monkeypox virus. However, COP-A44L gave better results.

Abstract
Epigenetic regulations play a crucial role in the expression of various genes that are important in the normal cell function. Any alteration in these epigenetic mechanisms can lead to the modification of histone and DNA resulting in the silencing or enhanced expression of some genes causing various diseases. Acetylation, methylation, ribosylation or phosphorylation of histone proteins modifies its interaction with the DNA, consequently changing the ratio of heterochromatin and euchromatin. Terminal lysine residues of histone proteins serve as potential targets of such epigenetic modifications. The current review focuses on the histone modifications, their contributing factors, role of these modifications on metabolism leading to cancer and methylation of histone in cancer affects the DNA repair mechanisms.

Abstract
Birds are very valuable indicators of species richness and endemic patterns in a specified ecosystem, which eventually help the scientist to measure the environmental degradation. The aim of present study was to know human knowledge and attitude toward urban birds in Faisalabad city, Pakistan. The study conducted in four consecutive months: November 2019 to February 2020. Population of birds was noted from eight residential towns of Faisalabad city, data were collected through questionnaire. Faisalabad has a reasonably large population of birds and present data show that, there is a significant difference between favorite bird of residential areas and institutions. The pigeon received the most likeness in bird population among residential area residents, while the myna received the least. The most popular bird in Faisalabad institutions was the sparrow, while the least popular bird was the common myna. Bird adaptation percentage of residential areas and institutional areas of Faisalabad was the highest for parrot and sparrow respectively. People in residential areas and institutions, on the other hand, adapted least to common myna. It is concluded that people of the study area like birds and offered food and high population of birds are present in study area.

Abstract
COVID-19, an infectious disease caused by a newly discovered enveloped virus (SARS-CoV-2), was first reported in Wuhan, China, in December 2019 and affected the whole world. The infected individual may develop symptoms such as high fever, cough, myalgia, lymphopenia, respiratory distress syndrome etc. or remain completely asymptomatic after the incubation period of two to fourteen days. As the virus is transmitted by inhaling infectious respiratory droplets that are produced by sneezing or coughing, so early and rapid diagnosis of the disease can prevent infection and transmission. In the current pandemic situation, the medical industry is looking for new technologies to monitor and control the spread of COVID-19. In this context, the current review article highlights the Artificial Intelligence methods that are playing an effective role in rapid, accurate and early diagnosis of the disease via pattern recognition, machine learning, expert system and fuzzy logic by improving cognitive behavior and reducing human error. Auto-encoder deep learning method, α-satellite, ACEMod and heterogeneous graph auto-encoder are AI approaches that determine the transfer rate of virus and are helpful in shaping public health and planning. In addition, CT scan, X-ray, MRI, and RT-PCR are some of the techniques that are being employed in the identification of COVID-19. We hope using AI techniques, the world can emerge from COVID-19 pandemic while mitigating social and economic crisis.

Abstract
Background The global health community has emphasized the importance of reporting epidemiological data by age and sex groups in the COVID-19 pandemic. However, age and sex disaggregated data of COVID-19 cases and deaths are rarely reported. Such data are very crucial for public to make truly informed choices about their own diseases risk and also for governments for public policy response. Objective To assess age and gender difference among COVID-19 cases and deaths in Nepal. Method This is a retrospective study which uses public data on COVID-19 cases and deaths released by Ministry of Health and Population, Government of Nepal from January to November, 2020. The data analysis was carried out using SPPS software version 26. Result Nepal reported 233,452 confirmed cases and 1,566 deaths of COVID-19 from 23 January 2020 to 30 November 2020. We found statistically significant differences on COVID-19 cases by age and gender in Nepal with higher number of cases among males of economically active age groups (20-60 years). Similarly, we found significant difference in COVID-19 mortality with more death occurred among male group compared to female group and with highest number of deaths among the people of above 60 years. Furthermore, we found differences in cases and deaths among provinces. Conclusion The age and gender differences in COVID cases and deaths in Nepal indicates needs of considering age and sex groups seriously while planning for testing, case management and vaccination against COVID-19 infections in Nepal.

Abstract
Background:PET/CT imaging of synovial angiogenesis using68Ga-RGD (cyclic tripeptide agent targeting αvβ3integrin) to study disease activity in rheumatoid arthritis (RA) has been demonstrated earlier in a few patients. However, post treatment changes in disease activity on68Ga-RGD2PET/CT imaging have not been adequately assessed.Objectives:To compare the performance of68Ga-RGD2PET/CT with disease activity score (DAS) 28 in assessing disease activity and treatment response in RA.Methods:Thirty patients (24F, 6M) aged 43±12 years with clinically diagnosed RA were prospectively studied. After calculation of DAS28 by a rheumatologist, all 30 patients underwent68Ga-RGD2PET/CT scan. Of these, 27 patients underwent a second68Ga-RGD2PET/CT scan and clinical assessment after at least 3 months of treatment. Total body and regional images of the upper limbs were acquired and interpreted by two nuclear medicine physicians blinded to the clinical findings. Joints showing focally increased tracer uptake compared to the background were considered positive and joints showing uptake equal to or less than background were considered negative. Data of 30 patients were used for inter-observer and inter-modality agreement calculations. Changes in PET parameters and DAS28 were compared in 27 patients to assess treatment response.Results:Out of 1560 joints examined in the initial scan, 394 were positive on PET/CT compared to 348 on clinical evaluation. Inter-observer agreement between nuclear medicine physicians was excellent (Cohen’s kappa 0.92, p<0.05) and inter-modality agreement between PET and clinical examination was moderate (Cohen’s kappa 0.55, p<0.05). The DAS28 and SUVmax values (highest and average) of 27 patients showed significant reduction on follow-up compared to the initial evaluation. There was significant correlation between percentage change in DAS28 and percentage change in scan parameters like PET positive joint counts (0.689, p<0.001), average SUVmax (0.712, p<0.001) and highest SUVmax values (0.558, p=0.003) of scan-positive joints in 27 patients. Additional advantages of68Ga-RGD2PET/CT included objective assessment, whole body evaluation of all small and large joints, and greater reproducibility.Conclusion:68Ga-RGD2PET/CT is a promising tool for objective assessment of disease activity and treatment response in patients with RA.Table 1.Clinical and PET parameters of the patientsParameterInitial data (n=27)Mean (SD)/Median (IQR)Follow-up data (n=27)Mean (SD)/Median (IQR)TJC(28)10 (5-13)3 (2-4)SJC(28)6 (3-7)1 (0-2)ESR25 (20-41)24 (18-35)PtGA6.0 (5.0-6.0)3.0 (2.0-4.0)DAS28(3)5.14 (0.85)3.74 (0.88)DAS28(4)5.60 (0.90)3.80 (0.96)PET positive Joints12 (7-8)4 (2-9)aSUVmax2.08 (1.68-2.52)1.79 (1.00-2.06)hSUVmax3.45 (2.71-4.70)3.34 (1.95-4.25)TJC/SJC: tender/swollen joint counts; ESR: erythrocyte sedimentation rate; PtGA: patients global assessment scale; DAS: disease activity score; aSUVmax/hSUVmax: average/highest SUVmax (maximum standardized uptake value); SD: standard deviation; IQR: interquartile rangeFigure 1.68Ga-RGD2PET scan of a 26-year female RA patient on treatment.A.Initial scan shows increased tracer uptake in multiple joints of upper and lower limbs and tendon sheaths of hands and ankle region (arrows); DAS28 was 4.56 (moderate disease activity) and ESR 12 mm/1sthour.B.

Abstract
A 30-year-old female presented with a 3-month history of erosive stomatitis and bullous lesions, along with recurrent episodes of abdominal pain. She was found to have a retroperitoneal lump in left lumbar region. Skin biopsy revealed bullous disorder. CT guided biopsy of the retroperitoneal mass was suggestive of inflammatory myofibroblastic tumor (IMT). She was started on oral steroids and supportive care, and surgery was being planned when she developed respiratory failure. CT chest revealed vertebral metastases. PET/CT for whole body work up revealed a left para-aortic mass along with multiple skeletal metastases. The patient was kept on conservative management. After 3 months, the patient has shown clinical improvement, and an exploratory laparotomy is now being planned for the excision of the tumor, followed by chemotherapy. This case of retroperitoneal IMT is rare in terms of skeletal metastases with paraneoplastic pemphigus.

Abstract
Acid lime (Citrus aurantifolia Swingle) is an important commercial fruit crop, cultivated from terai to high hill landscapes of Nepal. However, production and productivity is very low due to various reasons including infestations by various diseases and pests, lack of diseases and pests resistant and high yielding varieties. In this context, determination of genetic variation at molecular level is fundamental to citrus breeders for the development of elite cultivars with desirable traits. In the present study, Random Amplified Polymorphic DNA (RAPD) marker technique has been employed to assess genetic diversity in 60 acid lime landraces representing different agro-ecological zones of eastern Nepal. Nine selected arbitrary primers generated 79 RAPD fragments of which 75 were polymorphic (94.94%). Phenogram was constructed by NTSYSPC ver. 2.21i using UPGMA cluster analysis based on Jaccard’s similarity coefficient to deduce overall genetic diversity and relationships of the acidlime genotypes under study. Sixty acid lime landraces formed seven clusters and similarity value ranged from 38% to 98% with an average of 72%. Genetic variation at different agro-ecological zones was assessed using Popgene ver. 1.32 and found 47% to 69.6% polymorphism. Shannon’s index and Nei’s gene diversity showed highest level of acid lime diversity in Terai zone (PPB, 69.62%; H, 0.213; I, 0.325) followed by mid-hill zone (PPB, 67.09%; H, 0.208; I, 0.317). The results obtained will be useful to citrus breeders for elite cultivar development.

Abstract
Pesticides have wide spread use and their toxic residues have been reported in various environmental matrices. Thus, the determination of pesticide residues in food commodities such as vegetables, cereals, fruits, and other environmental components like soil, water has become increasingly essential requirement for consumers, producers and authorities for food quality control. Therefore, monitoring of residue level and exposure assessment of organophosphate group of pesticides namely dichlorovos and methyl parathion was carried out in 30 winter and summer vegetables supplied in Kathmandu valley. It was found that the MRL value of dichlorovos exceeded in three types of vegetables whereas in case of methyl parathion the MRL value exceeded in two types of vegetables only. The estimated average daily intake (EADI) of dichlorovos exceeded the acceptable daily intake (ADI) in 18 vegetables, whereas, regarding methyl parathion the EADI exceeded the ADI in 10 types of vegetables.

Abstract
OBJECTIVE To investigate the relationship between apoptotic cells and macrophages in the eutopic endometrium of women with and without endometriosis. DESIGN Retrospective analysis of archival uterine endometrial biopsy specimens. SETTING Institute for the Study and Treatment of Endometriosis, and university-based pathology and research laboratories. PATIENT(S) Fifty-one women with endometriosis and 24 healthy control subjects without endometriosis. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) The number of TUNEL+ (terminal deoxynucleotide transferase [TdT]-mediated deoxyuridine triphospate [dUTP] nick end-labeling-positive) (apoptotic) cells and CD68+ (CD68 positive) (macrophages). RESULT(S) Apoptotic cells and macrophage numbers were positively correlated in the eutopic endometrium of women with and without endometriosis. However, the number of apoptotic cells and the macrophage content in the endometrium of women with endometriosis was significantly reduced compared with that of healthy control subjects without endometriosis. Differences between apoptosis and macrophage numbers between the two populations were observed predominantly during the early proliferative phase of the menstrual cycle. CONCLUSION(S) The reduction in apoptosis described for endometrial cells in women with endometriosis may be related to reduced macrophage trafficking into the eutopic endomtrium during the early-proliferative phase of the menstrual cycle.

Abstract
An unusual case of retroperitoneal ectopic pregnancy is reported. The patient, a 34 year old nulligravida, underwent IVF/ET following bilateral salpingectomy. A small, degenerating, intrauterine gestational sac suggested failing intrauterine pregnancy. There was no intraperitoneal free fluid. On Day 41 after ET, the patient was hospitalized because of acute epigastric pains. A pseudocyst of the head of pancreas was demonstrated by CT scan. A day later, exploratory laparotomy, because of a precipitous drop in the hemoglobin, revealed a massive retroperitoneal hematoma and an embryo in the gestational sac attached to the head of pancreas and major blood vessels. The patient did well following surgery. The mechanisms of retroperitoneal embryo migration are discussed and literature is reviewed.

Abstract
BACKGROUND The aetiology of endometriosis is unknown. Ectopic dissemination of the endometrial cells gives origin to endometriotic lesions, but occurs in women with and without endometriosis. It has been suggested that increased ectopic cell survival facilitates their implantation. The objectives of this study were to evaluate endometrial apoptosis in women with endometriosis according to: (i) cyclic changes, (ii) glandular and stromal contribution, and (iii) stage of the disease. METHODS The subjects were women undergoing diagnostic laparoscopy and endometrial biopsies for suspected endometriosis. Spontaneous apoptosis was evaluated using TdT-mediated dUTP-biotin nick end-labelling (TUNEL) assay. Apoptotic cells per 10 mm(2) (apoptotic index) in an area of 10-50 mm(2) in 5 microm endometrial tissue sections were counted and location of these cells was recorded. RESULTS The apoptotic index in glandular epithelium was lower in endometriosis than controls (26.0 +/- 5.5 versus 51.2 +/- 9.7, P = 0.03) but not in the stroma (36.3 +/- 6.4 versus 48.4 +/- 11.3, NS). In controls, apoptosis was highest during the late secretory/menstrual and early proliferative phases and cyclic variability was apparent. In endometriosis, this cyclic variability was lost. There was a trend toward decreased apoptosis with increasing stage of the disease, but the differences lacked statistical significance. CONCLUSIONS Spontaneous apoptosis is decreased in the endometrial glands in women with endometriosis, especially during late secretory/menstrual and early proliferative phases of the cycle. This may indicate increased viability of endometrial cells shed during menses, facilitating their ectopic survival and implantation.

Abstract
Small bowel involvement by endometriosis occurs in about 0.5% of patients, but nodular endometriosis involving the entire wall of the terminal ileum is extremely rare. Endometriotic nodules protruding into the intestinal lumen may lead to chronic, partial, or acute complete small bowel obstruction and associated clinical changes. If obstruction is partial, preoperative diagnosis is difficult and seldom suspected, and no reliable diagnostic tests are available. At laparoscopic surgery, performed typically for associated pelvic endometriosis, bowel lesions may easily be overlooked, especially in women with abdominal adhesions from earlier surgery. Surgical injury, tension tears, or postoperative edema may contribute in such cases to the development of acute, complete small bowel obstruction, which may be difficult to differentiate from postoperative ileus. The patient may deteriorate rapidly and develop abdominal sepsis and multiple organ failure with high risk of mortality. Because of increased production of tumor necrosis factor-alpha by autologous monocytes, endometriosis may predispose to development of severe sepsis and septic shock.

Abstract
OBJECTIVE To describe the safety and efficacy of open laparoscopy as a method of access to the abdominal cavity for laparoscopic surgery. METHODS We reviewed retrospectively all cases of open laparoscopy we did between August 1970 and June 1999. RESULTS Twenty-seven (0.5%) of 5284 patients who had open laparoscopies during the study years developed complications related to primary access. Twenty-one had minor wound infections, four had minor hematomas, one developed an umbilical hernia that required reoperation, and one had an inadvertent injury to the small bowel that was repaired intraoperatively without adverse outcome. Access to the abdominal cavity was generally secured in 3-10 minutes. CONCLUSION Open laparoscopy was associated with no method failure or life-threatening complications. Minor and medium risk complications occurred at a rate of 0.5%. Open laparoscopy is a safe, effective method of accessing the abdominal cavity.

Abstract
Zona-free human oocytes are frequently encountered in in-vitro fertilization (IVF) laboratories. The oocytes escape out of the zona pellucida, following zona fracture, which can occur during oocyte retrieval or manipulation, but occasionally may be the result of increased zona fragility. Some of the zona-free oocytes are mature and morphologically healthy; nevertheless, all are typically discarded. In this report, we demonstrate that zona-free oocytes can be fertilized normally using intracytoplasmic sperm injection (ICSI) and can subsequently develop without zona to the blastocyst stage in vitro. We therefore suggest that those mature and morphologically normal zona-free oocytes may be rescued, fertilized with ICSI and then cultured to the blastocyst stage for subsequent transfer or cryopreservation.

Abstract
OBJECTIVE To compare the ability of peripheral blood monocytes (PBM) and peritoneal macrophages (PM) to mediate the in vitro cytolysis of endometrial cells from eutopic and ectopic endometrium in women with endometriosis. DESIGN Prospective study of immune function. SETTING Institute for the Study and Treatment of Endometriosis and university-based research laboratories. PATIENT(S) Twenty-four women with endometriosis (15 in stage I/II, 9 in stage III/IV) and 4 patients treated with GnRH agonists. INTERVENTION(S) Peritoneal fluid and peripheral blood were sampled and eutopic and ectopic endometrium were biopsied during diagnostic laparoscopy. MAIN OUTCOME MEASURE(S) Lysis of autologous endometrial cells. RESULT(S) Peripheral blood monocytes were significantly more cytolytic than peritoneal macrophages against autologous uterine endometrial cells. However, PBM and PM displayed a similar degree of cytolysis against a hepatoma cell line. Ectopic endometrial cells were significantly more resistant to cytolysis by autologous PBMC than were matched eutopic endometrial cells, and were completely resistant to cytolysis by autologous PM. CONCLUSION(S) The reduced capacity of PM from women with endometriosis to mediate the destruction of endometrial cells coupled with the increased resistance of ectopic endometrial cells to macrophage-mediated cytolysis may facilitate the survival of these cells within the peritoneal cavity of women with endometriosis.

Abstract
OBJECTIVE To evaluate spontaneous apoptosis in single-cell suspensions of eutopic and ectopic endometrium from women with endometriosis and in eutopic endometrium from fertile controls without endometriosis. DESIGN Paired specimens of eutopic and ectopic endometrial tissue from patients with endometriosis and eutopic endometrium from controls were assessed for spontaneous apoptosis. SETTING Institute for the Study and Treatment of Endometriosis and university-based research laboratories. PATIENT(S) Fertile controls (n = 10) and women with untreated endometriosis (n = 16). INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Spontaneous apoptosis assessed with an ELISA-based cell death detection kit. RESULT(S) Spontaneous apoptosis (monitored by absorbance) of eutopic endometrium from patients with endometriosis and fertile controls was 0.63 +/- 0.1 and 1.43 +/- 0.11, respectively. Among patients with endometriosis, spontaneous apoptosis of ectopic endometrium was 0.26 +/- 0.06. Decreased apoptosis of ectopic versus eutopic endometrium was observed independent of cycle phase. CONCLUSION(S) The susceptibility of endometrial tissue to spontaneous apoptosis is significantly lower in women with endometriosis than in fertile controls. We suggest that decreased susceptibility of endometrial tissue to apoptosis contributes to the etiology or pathogenesis of endometriosis.

Abstract
OBJECTIVE To report an unusual case of embryo implantation and superfetation. DESIGN Retrospective case analysis. SETTING Oak Brook Fertility Center. PATIENT(S) A 41-year-old woman underwent two consecutive ovarian stimulation cycles interrupted by a normal menstrual period. Ovulation and implantation occurred during both cycles. The first embryo conceived developed normally until term; the second failed to develop. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Retrospective analysis of stored blood samples for serum E2, P, and beta-hCG levels. RESULT(S) Rising beta-hCG levels during menstruation indicated normal embryonic implantation in the absence of adequate E2 and P support. During subsequent ovarian stimulation, there was a normal follicular and E2 response and normal ovulation in spite of the ongoing pregnancy. The second embryo, conceived during the second cycle of stimulation, implanted but failed to develop. CONCLUSION(S) This unusual case indicates that E2, P, and endometrial thickness requirements for successful implantation may not always be as critical as postulated previously. The absence of a decidual response might have facilitated superfetation.

Abstract
PURPOSE The purpose of this study was to evaluate the clinical effectiveness of subcutaneous estradiol pellets in donor oocyte recipients with an inadequate endometrial response. METHODS The subjects were 13 women with ovarian failure and a maximal endometrial thickness < 10 mm on standard estrogen regimens, as demonstrated during mock and/or prior oocyte donation cycles. They underwent pellet implantation (100-250 mg of estradiol) 6-13 weeks before oocyte donation. RESULTS maximal (mean +/- SD) endometrial thickness was 8.7 +/- 1.5 mm on standard regimens, in contrast to 11.7 +/- 1.8 mm on pellets, while estradiol levels were 674 +/- 844 and 815 +/- 706 pg/ml, respectively. The estradiol:estrone ratio on pellets was > 1. There was 1 pregnancy with early loss during 10 cycles on other estrogen regimens and 12 pregnancies during 19 cycles on pellets. The pregnancy and implantation rates were, respectively, 63 and 27% on pellets and 41 and 14% on standard regimens in historical controls. CONCLUSIONS We conclude that estradiol pellets after a single administration provide constant estradiol levels extending into the first trimester of pregnancy, a physiologic estradiol:estrone ratio, and a better endometrial response than standard estrogen regimens. Implantation and pregnancy rates are higher. This approach may be especially suitable for recipients with a poor endometrial response.

Abstract
OBJECTIVE To compare demographic, epidemiologic, and medical data and to evaluate diagnostic trends in women with endometriosis and chronic pelvic pain symptoms or endometriosis and infertility. DESIGN Retrospective analysis. SETTING Institute for the Study and Treatment of Endometriosis. PATIENT(S) Six hundred ninety-three consecutive patients with endometriosis and chronic pelvic pain (n = 357) or endometriosis and infertility (n = 336). INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Demographic and epidemiologic parameters, diagnostic trends. RESULT(S) Women with pelvic symptoms were younger, had less formal education, more frequent family history, and higher frequency and intensity of pelvic complaints. Mean ages at first symptom and diagnosis were lower in the pain group, but stage of endometriosis at first diagnosis was more advanced. The mean "diagnostic delay" was longer in the pelvic pain than in the infertile group (6.35 versus 3.13 years), but it decreased during three consecutive 5-year intervals in both groups, and there was also a gradual decrease in the frequency of advanced endometriosis at the time of first diagnosis. CONCLUSION(S) Demographic and epidemiologic parameters in women with endometriosis differ, depending whether chronic pelvic pain or infertility are the presenting symptoms. In the pain group, diagnostic delay is longer and endometriosis at diagnostic laparoscopy more advanced, indicating progressiveness of the disease. During the last 15 years, diagnostic delay steadily decreased and the frequency of advanced endometriosis at first diagnosis declined.
