To determine the rate of success of external cephalic version in low risk breech presentations and possible factors affecting its success in POF hospital, Wah Cantt.

Abstract   Background The caesarean section rate  is on the rise for various reasons. One of the reason is breech presentation . External cephalic version is a procedure to manipulate the baby from breech to cephalic presentation externally through the maternal abdomen under USG guidance . Success in ECV decreases the breech presentation and  hence caesarean section rate . Methods This retrospective study was conducted by Wah Medical College in POF hospital from10 Oct 2015- 10 Oct 2019 after approval from the ethical committee .  It included 56 low risk singleton  breech presentations from 36 wks- 40 wks after taking their informed consent  While those with < than 36 wks (primis) and >40 wks gestation, refusal to ECV , with absolute contraindication to ECV& with medical and obstetric complications (ie scarred uterus, liquor <than 8 cm & > than 17 cm, fetal growth restriction, preclampsia, gestational diabetes & abnormal cardiotocography) were excluded  from the study. ECV was performed by single obstetrician in labour room with facilities  of cardiotocograph and emergency caesarean section. Cardiotocography of the fetus  for 30-40 min was done just before & after the procedure of ECV. ECV was declared successful on cofirming head of the fetus occupying the lower uterine segment on ultrasound.  .Number  of successful ECVs & specific factors  of the women & the baby (age . parity, amniotic fluid index ,type of breech, engagement of breech, position of back of baby)  were chosen to observe their effect on success of  ECV. Results External cephalic version was successful in 27 (48.2%)  & unsuccessful in 29 (51.8%)of women .Multiparity , unengaged breech & type of breech (complete flexed) ( with p values .001, .000 & .001 respectively) had statistically significant positive association with successful external cephalic version. Conclusion ECV should be offered to all  women with low risk breech presentations. Knowledge of factors predictive of ECV success can be utilized in selecting cases for ECV &counselling the women regarding the success and failure of ECV.   &nbsp

Reliability Of Transvaginal Ultrasound Measured Endometrial Thickness In Diagnosis Of Endometrial Cancer In Postmenopausal Women

Abstract Objective: Dilatation and curettage have been replaced by ultrasound measurement of uterine endometrial thickness (ET) especially by Transvaginal ultrasound (TVS) as a first step in the workup of women with postmenopausal bleeding for many years. Still, there is no unanimity for endometrial thickness cut-off value to define abnormality. We used an endometrial thickness of 4mm as a cut-off value in this study. Methods: This cross-sectional validation study included 120 patients who presented with postmenopausal bleeding in OPD of POF hospital from 01-12-2017 to 1-06-2018.TVS measured endometrial thickness ≥4mm was assumed positive for malignancy and ˂ 4 mm was taken negative for malignancy. The TVS findings of patients were compared with the histopathology report of endometrial sampling, which was performed in OPD by manual vacuum aspirator (MVA). Histopathology report was taken as a reference standard to confirm or refute the diagnosis of transvaginal ultrasound. Results: On TVS, 54 patients had ≥ 4mm endometrial thickness (taken positive for malignancy) while 66 patients had <4 mm endometrial thickness (taken negative for malignancy). Histopathology of the endometrium (reference standard) revealed that 47 (39.17%) patients had malignancy and 73(60.83%) patients did not have malignancy. The reliability of transvaginal ultrasound (TVS) using 4mm cut-off point ET in detecting endometrial malignancy in patients presenting with uterine bleeding after menopause, keeping histopathological findings as a reference standard showed 89.36% sensitivity, 83.56%, specificity, 92.42% negative predictive value and 77.78% positive predictive value & 85.83% accuracy rate. Conclusion: We concluded that there was a low probability of endometrial malignancy in women with ˂ 4 mm transvaginal ultrasound (TVS)measured endometrial thickness (ET).TVS  may replace invasive endometrial sampling in cases of postmenopausal bleeding with ˂ 4mm ET

Phosphorus release kinetics of applied phosphate is influenced by time and organic sources in clay loam and sandy clay loam soils

Adsorption and precipitation are major mechanisms that play an imperative role in immobilization of phosphorus (P) in various texture soils thus limiting the crop yields. Soil organic matter (SOM) can improve P bioavailability by decreasing its sorption in soils. The aim of current experiment was to investigate best organic source to reduce P sorption in different texture soils. Press mud (PM), farmyard manure (FYM), processed city waste (CW) and poultry litter (PL) were used to examine P availability in clay loam and sandy clay loam soils. Organic sources were added at the rate of 10 t ha-1 according to organic matter content in clay pots having 10 kg soil capacity. Phosphorus was added at the rate of 200 mg P kg-1 soil by using KH2PO4 and moisture was maintained at 60% water holding capacity. Results showed higher adsorption of P (122 mg kg-1) in clay loam soil as compared to the sandy clay loam (132 mg kg-1) soil. The Olsen P influenced by organic amendments was in the order of CW > PL > FYM > PM > control. There was a significant correlation between P released by organic sources with time and soil texture. It is concluded that application of CW is best regarding P release in different texture soils

Identification of novel and safe fungicidal molecules against fusarium oxysporum from plant essential oils: in vitro and computational approaches.

Phytopathogenic fungi are serious threats in the agriculture sector especially in fruit and vegetable production. The use of plant essential oil as antifungal agents has been in practice from many years. Plant essential oils (PEOs) of Cuminum cyminum, Trachyspermum ammi, Azadirachta indica, Syzygium aromaticum, Moringa oleifera, Mentha spicata, Eucalyptus grandis, Allium sativum, and Citrus sinensis were tested against Fusarium oxysporum. Three phase trials consist of lab testing (MIC and MFC), field testing (seed treatment and foliar spray), and computer-aided fungicide design (CAFD). Two concentrations (25 and 50 μl/ml) have been used to asses MIC while MFC was assessed at four concentrations (25, 50, 75, and 100 μl/ml). C. sinensis showed the largest inhibition zone (47.5 and 46.3 m2) for both concentrations. The lowest disease incidence and disease severity were recorded in treatments with C. sinensis PEO. Citrus sinensis that qualified in laboratory and field trials was selected for CAFD. The chemical compounds of C. sinensis PEO were docked with polyketide synthase beta-ketoacyl synthase domain of F. oxysporum by AutoDock Vina. The best docked complex was formed by nootkatone with -6.0 kcal/mol binding affinity. Pharmacophore of the top seven C. sinensis PEO compounds was used for merged pharmacophore generation. The best pharmacophore model with 0.8492 score was screened against the CMNP database. Top hit compounds from screening were selected and docked with polyketide synthase beta-ketoacyl synthase domain. Four compounds with the highest binding affinity and hydrogen bonding were selected for confirmation of lead molecule by doing MD simulation. The polyketide synthase-CMNPD24498 showed the highest stability throughout 80 ns run of MD simulation. CMNPD24498 (FW054-1) from Verrucosispora was selected as the lead compound against F. oxysporum

Integrative analysis of WDR12 as a potential prognostic and immunological biomarker in multiple human tumors

Background: Mammalian WD-repeat protein 12 (WDR12), a family member of proteins containing repeats of tryptophan-aspartic acid (WD), is a potential homolog of yeast Ytm1p and consists of seven repeats of WD.Aim of the study: This study aims to investigate the potential oncogenic effects of WDR12 in various human malignancies throughout a pan-cancer analysis that has been carried out to examine the various patterns in which this gene is expressed and behaves in tumor tissues.Methods: Herein, we used The Cancer Genome Atlas (TCGA) and various computational tools to explore expression profiles, prognostic relevance, genetic mutations, immune cell infiltration, as well as the functional characteristics of WDR12 in multiple human cancers.Results: We found that WDR12 was inconsistently expressed in various cancers and that variations in WDR12 expression predicted survival consequences for cancer patients. Furthermore, we observed a significant correlation between WDR12 gene mutation levels and the prognosis of some tumors. Furthermore, significant correlations were found between WDR12 expression patterns and cancer-associated fibroblast (CAF) infiltration, myeloid-derived suppressor cells (MDSCs), tumor mutation burden, microsatellite instability and immunoregulators. Ultimately, pathway enrichment analysis revealed that WDR12-related pathways are involved in carcinogenesis.Conclusions: The findings of our study are stisfactory, demonstrating that WDR12 could serve as a promising reliable prognostic biomarker, as well as a therapeutic target for novel cancer therapeutic approaches

A comprehensive perspective of traditional Arabic or Islamic medicinal plants as an adjuvant therapy against COVID-19

COVID-19 is a pulmonary disease caused by SARS-CoV-2. More than 200 million individuals are infected by this globally. Pyrexia, coughing, shortness of breath, headaches, diarrhoea, sore throats, and body aches are among the typical symptoms of COVID-19. The virus enters into the host body by interacting with the ACE2 receptor. Despite many SARS-CoV-2 vaccines manufactured by distinct strategies but any evidence-based particular medication to combat COVID-19 is not available yet. However, further research is required to determine the safety and effectiveness profile of the present therapeutic approaches. In this study, we provide a summary of Traditional Arabic or Islamic medicinal (TAIM) plants’ historical use and their present role as adjuvant therapy for COVID-19. Herein, six medicinal plants Aloe barbadensis Miller, Olea europaea, Trigonella foenum-graecum, Nigella sativa, Cassia angustifolia, and Ficus carica have been studied based upon their pharmacological activities against viral infections. These plants include phytochemicals that have antiviral, immunomodulatory, antiasthmatic, antipyretic, and antitussive properties. These bioactive substances could be employed to control symptoms and enhance the development of a possible COVID-19 medicinal synthesis. To determine whether or if these TAIMs may be used as adjuvant therapy and are appropriate, a detailed evaluation is advised

A mechanistic insight into chemical cues and interactions involved in herbivory induced jasmonate mediated plant defense mechanism

The first step in plant defense mechanism is to sense the insect attack stimulus. Plant sensitivity of an insect attack is the first step of defense. Molecules generated by the oral secretion of the insect interact with the plant receptors to trigger plant defense mechanisms. We selected some highly cited insect elicitors molecules, volicitin, caeliferin, bruchin which interact with plant defense by interacting with plant elicitors (systemin, inceptin and peps) located on the plant cell surface. This interaction activates plant receptors SYR1, LRR, PEPR and triggers downstream defense signaling. The octadecanoid pathways, involving enzymes allene oxide synthase (AOS) and Hydroxyperoxide lyase (HPL) are activated. These enzymes mediate production of green leafy volatiles and Jasmonic acid by interacting with hydroxperoxide molecules. We docked the elicitors with receptors and enzymes with substrates in the pathway of JA production. Phe was found to be an important amino acid that interacts with 13-hydroxyperoxides in the case of AOS to produce JA but not in the case of HPL. JA is converted to JA-Ile which shows strong binding with COI1 and COI1-JA-Ile complex docked with JAZ which showed strong interaction with ve hydrogens and one salt bridge bond. AOS and HPL showed less than 40% identity for sequence and structure alignment. AOS and HPL had shown an interaction between each other and showed a common interaction partner of the Lipoxygenase family. HPL shows interaction with ADH2 (Alcohol dehydrogenase) involved in GLVs production. AOS also showed interaction partner AOC, COI1 and OPR1 which are involved in JA-induced plant defense mechanism.peer-reviewe

Thus novel classes of anti-diabetic drugs are required. The contribution of computer-aided drug design (CADD) techniques in the identification of antidiabetic agents has been discussed in this dissertation. In chapter 1, I introduced the background and current status of CADD for diabetes mellitus, my research goals and the strategies used in this dissertation. In chapter 2, by computational analysis of Canavalia ensiformis protein, I demonstrated that it’s conserved amino acid sequence homologous to human insulin protein. The plant insulin (UniProt ID: Q7M217) used as alternative source of human insulin showed its mechanism of action in terms of optimal binding mode with available antidiabetic drugs. A biphenyl derivative was identified as a lead compound and designed its analogs. Molecular docking analyses showed that four analogs could be recommended as antidiabetic agents with suitable drug-like properties as compared with a standard antidiabetic drug (aleglitazar). In chapter 3, plant-derived protein tyrosine phosphatase non-receptor type 1 (PTPN1) inhibitors possessing antidiabetic activity were used for pharmacophore model generation. The pharmacophore-based screening of plant-derived compounds of the ZINC database was conducted using ZINCpharmer; screened hits were assessed to evaluate their drug-likeness, pharmacokinetics, detailed binding behavior and aggregator possibility. The crystal structure of PTPN1 (PDB ID: 3EAX) was used as a molecular target for docking analyses of screened dataset. Through the virtual screening and in silico pharmacology protocols ZINC30731533 (isosilybin) was identified as a lead compound with optimal properties. Chapter 4 sum-ups the achievement and originality of this research work. It concluded with significant aspects of the current research scheme in the area of drug discovery
