Sidi, M Department of Medical Radiography, Faculty of Allied Health Sciences, Bayero University, Kano Department of Radiology, Bayero University/Aminu Kano Teaching Hospital Kano *Corresponding author: ABSTRACT Hysterosalphingography (HSG) is a special radiological procedure that is used to assess the patency and the structure of the uterus and Fallopian tubes. The main role of HSG is the study of the Fallopian tubes in infertility. Discomfort, anxiety, and pain that might arise as a result of the procedure and may vary depending on the individual’s perception. The patient’s perception of a procedure plays an important role in its acceptance. The study aims at evaluating the perception of patients undergoing HSG examination in Kano metropolis. The study design was prospective and cross Radiology Departments of four hospitals in the Kano metropolis from December 2018 to March 2019. A non-probability sampling method was employed in the study. An ethical clearance to conduct the study was obtained from the Human Research and Ethics Committee of the Kano State Ministry of Health. A structured questionnaire was used as an instrument for data collection. The questionnaire was validated by experienced colleagues and using pilot study the reliability of the measuring tool was tested and the Chronbach reliability coefficient was found to be 0.79. Two hundred and fifty six questionnaires were administered to the selected respondents. An informed consent was obtained from all the selected respondents. The obtained data were analyzed using SPSS version 21.0. Out of the 256 (100%) administered questionnaires, 237 (92.6%) were returned, and 226 (88.3%) were properly filled. In 189 (83.63%) respondents, infertility was found to be the indication for the procedure. 82 (36.3%) of the respondents believed the procedure was for diagnostic purpose, 78 (34.5%) for therapeutic and 28.3% for diagnostic and therapeutic. Patients undergoing HSG in Kano metropolis had a negative perception towards the procedure.
Chronic-periodontitis: could it be a connived-culprit of COVID-19?

Periodontitis is a multi-factorial disease resulting in the disruption of the attachment apparatus. COVID-19 has been alarming to many nations despite consistent efforts. Research has been continuously going on to curb the spread of the disease by gaining knowledge on the insights of the pathology of the disease. The current exploratory research establishes a correlation between periodontitis and COVID-19 and the impact of periodontal health in COVID affected patients. A search was performed using three data bases, PubMed, Scopus and Google Scholar published from 2019 to 2020. The keywords used for the search were COVID-19, and pathogenesis of periodontitis. The results of the search resulted in many reviews, original research, systematic reviews, case reports, etc. The critical selection of the articles especially systematic reviews was given utmost importance. Much less research has been done on the correlation of periodontitis to COVID-19. On the basis of search using the above mentioned keywords, a total of 26 articles were selected out of which only 21 articles were considered for the present exploratory review. The present review provides an insight into the pathogenic aspects of both periodontitis and COVID-19 and helps in establishing an ally which has been minimally explored to date. The pathogenesis of COVID shows a close similarity to periodontitis and henceforth a possible connection of the severity of COVID in patients suffering with chronic periodontitis. Periodontitis presents itself as a risk factor for many systemic diseases, and nevertheless, it has shown a possible similarity in the pathophysiology of COVID-19.

CLINICAL AND MORPHOLOGICAL FEATURES OF LUMINAL A SUBTYPE OF INVASIVE DUCTAL BREAST CANCER

The aim of this article was to study clinical and morphological features of luminal A subtype of breast cancer to assess its relationship with disease progression. Methods: This study included 79 patients with luminal A subtype of breast cancer who treatment in 2017 at the Lviv State Oncological Regional Treatment and Diagnostic Center. The Luminal A subtype was identified by immunohistochemistry (IHC) as ER+, PR+/-, HER2- and Ki-67 less than 20 percent on surgically resected breast cancer tissue. Results: The mean age of patients was 60,41±12,25 (range, 32–85 years), 26 (32,9%) were under 55 years. Nottingham Histologic Grade distribution was as follows: G1 – 10 (12,66%), G2 – 56 (70,88%), and G3 – 13 (16,46%) cases. Clinical stage II – 35 (44,3%) and III – 31 (39,24%) was observed. Menopausal status was in 67,1% of cases. Morphological analysis of the tumor tissue showed that except alveolar structures, there were trabecular, solid, tubular structures and separately located groups of tumor cells. The stromal component of the tumor was weak or moderate, most tumors showed minimal or marked inflammatory infiltration and low proliferative activity. Conclusions: To predict the probability of lymphogenic metastasis should be considered: menstrual function, histologic grade, the presence of alveolar structures in the infiltrative component, the different types of structures in the infiltrative component, hyalinosis in the stroma of the tumor node and inflammatory infiltration of tumor.
Prospects of plant extracts in progressive agriculture: A Review

Since the dawn of time, Indian agriculture has been plagued by a variety of destructive problems such as weeds, fungi, and insect pests, all of which have resulted in a rapid decrease in yields. Weeds compete with crop plants, reducing crop yields by 5 to 50 percent. Insect pests are farmers' worst enemies because they eat crops, stored grains, and serve as a vector for livestock diseases. Various fungi ruin agricultural and horticultural crops, causing economic losses and posing a health risk to consumers due to mycotoxins created by the fungi. Chemicals are used to monitor many of these bio agents, but their widespread use has resulted in weed, fungus, and pest resistance, as well as higher costs, residual toxicity levels, resulting in fertile lands being infertile and poisonous. The best solution for this is to use indigenous traditional methods of control used by farmers, such as plants that were once common all over the world but have nearly disappeared in developed countries due to the introduction and use of modern synthetic chemicals, and are now restricted to only a few regions of developing countries. Plant extracts, according to various reports, contain a variety of bioactive components that can regulate many of these crop-destroying agents. The aim of this paper is to summarize the results of using plant extracts to monitor plant bio agents. Plant extracts are cheap, environmentally friendly, readily available, and are therefore recommended for sustainable agricultural production
A NEW STEREO DENSE MATCHING BENCHMARK DATASET FOR DEEP LEARNING

Abstract. Stereo dense matching is a fundamental task for 3D scene reconstruction. Recently, deep learning based methods have proven effective on some benchmark datasets, for example Middlebury and KITTI stereo. However, it is not easy to find a training dataset for aerial photogrammetry. Generating ground truth data for real scenes is a challenging task. In the photogrammetry community, many evaluation methods use digital surface models (DSM) to generate the ground truth disparity for the stereo pairs, but in this case interpolation may bring errors in the estimated disparity. In this paper, we publish a stereo dense matching dataset based on ISPRS Vaihingen dataset, and use it to evaluate some traditional and deep learning based methods. The evaluation shows that learning-based methods outperform traditional methods significantly when the fine tuning is done on a similar landscape. The benchmark also investigates the impact of the base to height ratio on the performance of the evaluated methods. The dataset can be found in https://github.com/whuwuteng/benchmark_ISPRS2021.
Optical Methods For Deep-Tissue Imaging, Precise Mapping Of Cellular Topography And Single-Molecule Stoichiometry Analysis

Optimization of illumination and detection optics is pivotal for multiphoton imaging in highly scattering tissue and the objective lens is the central component in both of these pathways. To better understand how basic lens parameters (NA, magnification, field number) affect fluorescence collection and image quality, a twodetector setup was used with a specialized sample cell to separate measurement of 1 This chapter was previously published as: Singh, A. , McMullen, J.

Oxidative Desulfurization of Diesel Fuel Using Three Kinds of Carboxylic Acids Supported by Iron(III) Chloride

In the industry, hydrodesulfurization (HDS) is currently the major trend in hydrocarbons purification with regard to the removal of sulfur impurities in their hydrotreating using solid catalysts. However, this operation has a relatively low efficiency in terms of the removal of polycyclic organosulfur species such as dibenzothiophenes and their alkyl derivatives. In addition, it requires harsh operating conditions such as high temperatures (300–400°C) and high pressures (20–130 atm) which leads to very high capital and operating costs (Andevary et al., 2020; Grange, 1980).
Uncorrected Proof ) Title : Psychometric Properties of the Persian Word Pairs Task for Declarative Memory Assessment Running Title : Persian Word Pairs Task for Declarative Memory Assessment

Objective: According to the declarative/procedural model, the semantic aspect of language depends on the brain structures responsible for declarative memory. The word pairs task is a common tool for evaluating declarative memory. The current study aimed to design a valid and reliable task for evaluating declarative memory in Persian children at learning and retention stages and to investigate its relationship with the semantic aspect of language. Method: A panel of experts agreed on the content validity of the proposed task. The reliability of the task was determined using internal consistency and test-retest reliability. A total of 31 typically developing children aged 7-9 years of age participated in this study. Results: The content validity of all the 42 word pairs calculated as one. The testretest reliability showed a correlation coefficient of . 825 (P < 0.001). The task showed acceptable internal consistency (Cronbach’s alpha 0.880). The results of correlation analysis showed no significant relationship between declarative memory and semantic aspect. The regression analysis, however, showed that the retention stage could explain 24.2% of the variation of semantic aspect. Conclusion: It seems that the word pairs task has good validity and reliability for evaluating declarative memory. The task applied to evaluate the semantic aspect can be one of the potential causes for the lack of a relationship between semantic aspect and declarative memory. The participant score in the retention stage can be predicted concerning his/her performance at the semantic aspect.

Sentinel Lymph Node Biopsy in Early Breast Cancer Using the Indocyanine Green Fluorescence Technique: A Validation Study

INTRODUCTION: Introduction: Sentinel lymph node biopsy (SLNB) is now recognized as the standard of care for early breast cancer patients with negative axillary lymph nodes. Various approaches for Sentinel Lymph Node (SLN) identification using either the blue dye method or scintigraphy alone or their combination have been proposed. However, this method is costly and may not be applicable in certain developing countries. SLNB involving the use of indocyanine green (ICG) offers several advantages, and it is valid and safe when in direct comparison with the blue dye method and scintigraphy. Hence, we performed SLNB using this method in early breast cancer as the first center that involves the use of ICG in Malaysia. We performed validation study on this method with the aims to determine its sensitivity and safety profile. MATERIALS AND METHODS: This is a validation and non-randomised prospective observational study involving 20 patients underwent SLNB wherein ICG is used for localisation. The patients were recruited according to the recommendations stipulated in the Malaysia Clinical Practice Guideline. RESULT: The average number of SLNs removed per patient was 4.0 (range, 3–6) with sentinel lymph nodes detection rate at 98.75% (79/80). The false negative rate is at 5%. No adverse events were observed in all cases. CONCLUSION: The ICG fluorescence method is simple, reliable and safe. Moreover, it demonstrates a high SLN detection rate with a low false-negative rate, and it does not require a special instrument for radioisotope use.
Capsular Warning Syndrome - A Case Series and Discussion on Management Dilemmas.

BACKGROUND The term 'Capsular warning syndrome (CWS)' refers to recurrent, stereotypical transient ischemic attacks, either motor, sensory or both, without cortical symptoms or signs. Of these patients, 42-71% go on to develop infarcts. There are no defined treatment guidelines for this lesser known entity. METHODS We studied 9 patients who presented over last 2 years to our hospital with recurrent and stereotypical transient ischemic attacks suggestive of capsular warning syndrome. Their clinical characteristics, neuroimaging findings, relevant etiological investigations, management and outcomes were studied. RESULTS Seven out of 9 patients were under 40 years of age. The commonest presentation in our series was a pure motor syndrome. The duration of neurologic deficits ranged from 5 minutes to 20 minutes with complete recovery in between episodes. Three patients had concordant abnormalities on CT brain angiography. Five out of 9 patients received IV thrombolysis with t-PA. One patient worsened neurologically post thrombolysis, whilst the others improved clinically. DISCUSSION Despite multiple hypotheses, the pathogenesis and management of CWS has not been established clearly. Due to fluctuating neurological symptoms with complete recovery in between the episodes, there is a dilemma concerning treatment of such patients with intravenous thrombolysis. However, intravenous thrombolysis appears to be safe in CWS as in acute ischemic stroke, followed by treatment with antiplatelet agents.
Serendipity Identification Using Distance-Based Approach

The recommendation system is a method for helping consumers to find products that fit their preferences. However, recommendations that are merely based on user preference are no longer satisfactory. Consumers expect recommendations that are novel, unexpected, and relevant. It requires the development of a serendipity recommendation system that matches the serendipity data character. However, there are still debates among researchers about the available common definition of serendipity. Therefore, our study proposes a work to identify serendipity data's character by directly using serendipity data ground truth from the famous Movielens dataset. The serendipity data identification is based on a distance-based approach using collaborative filtering and k-means clustering algorithms. Collaborative filtering is used to calculate the similarity value between data, while k-means is used to cluster the collaborative filtering data. The resulting clusters are used to determine the position of the serendipity cluster. The result of this study shows that the average distance between the recommended movie cluster and the serendipity movie cluster is 0.85 units, which is neither the closest cluster nor the farthest cluster from the recommended movie cluster. Keyword—Serendipity, Collaborative Filtering, K-Means.
In Vitro Propagation of Tribulus terrestris with IAA and BAP Concentrations

Tribulus terrestris is conventionally propagated using seeds but has limited germination capacity. One approach that can be done for this plant multiplication is in vitro tissue culture. This study was conducted to determine the growth potential of T. terrestris in vitro by the addition of auxin (IAA) and cytokinin (BAP) as growth regulators at several concentrations. The study was conducted at the Laboratory of Plant Physiology and Biotechnology, Faculty of Agriculture, Universitas Sebelas Maret Surakarta from February to December 2017. The experiment employed factorial Completely Randomized Design (CRD) method with 2 factors, namely IAA concentration (0 ppm, 0.1 ppm, 0.2 ppm, 0.3 ppm), and BAP concentration (0 ppm, 0.3 ppm, 0.5 ppm, 0.7 ppm). The observed growth parameters were shoot emergence time, leaf emergence time, root emergence time, number of leaves, and number of roots. Data were analyzed using analysis of variance followed by DMRT with a 95% confidence level. The results showed that the addition of IAA only affects leaf emergence time, while the addition of BAP had a significant effect on the leaf emergence time and number of leaves. The interactions between IAA and BAP had a significant effect on leaf emergence time.
Uncorrected Proof ) Title : Differential Aspects of Natural and Morphine Reward-Related Behaviors in Conditioned Place Preference Paradigm Running title : Natural-and morphine-induced reward

Natural rewards are essential for animal survival. On the other hand, drug-seeking behaviours can be maladaptive and endanger survival. The present study was conducted to enhance our understanding of how animals respond to food and morphine as natural and drug rewards, respectively, in a conditioned place preference (CPP) paradigm. We designed a protocol to induce food-CPP and compare it as a natural reward with morphine-CPP in rats. The protocol for reward induction in all groups (foods and morphine) consisted of three phases: pre-test, conditioning, and post-test. In morphine groups, we injected morphine as a reward (5 mg/kg, s.c.), and for inducing natural-reward, we used two different protocols, by one of the rats were deprived of food for 24h. In the other method, rats were restricted for food for 14 days. During the conditioning period, animals received daily chow, biscuit, or popcorn as a reward inducer. Results revealed that CPP did not induce in food-deprived rats. A combination of food restriction (as a facilitator) and a biscuit or popcorn induced reward using CPP. In contrast, food deprivation did not facilitate food-CPP in response to regular food. Interestingly the CPP score of the group which received biscuit during a 7-day conditioning period was more than that of the morphine group. In conclusion, food restriction could be a better protocol than food deprivation to facilitate food reward.
IMPROVING LULC CLASSIFICATION FROM SATELLITE IMAGERY USING DEEP LEARNING – EUROSAT DATASET

Abstract. Machine learning (ML) has proven useful for a very large number of applications in several domains. It has realized a remarkable growth in remote-sensing image analysis over the past few years. Deep Learning (DL) a subset of machine learning were applied in this work to achieve a better classification of Land Use Land Cover (LULC) in satellite imagery using Convolutional Neural Networks (CNNs). EuroSAT benchmarking data set is used as training data set which uses Sentinel-2 satellite images. Sentinel-2 provides images with 13 spectral feature bands, but surprisingly little attention has been paid to these features in deep learning models. The majority of applications focused only on using RGB due to high availability of the RGB models in computer vision. While RGB gives an accuracy of 96.83% using CNN, we are presenting two approaches to improve the classification performance of Sentinel-2 images. In the first approach, features are extracted from 13 spectral feature bands of Sentinel-2 instead of RGB which leads to accuracy of 98.78%. In the second approach features are extracted from 13 spectral bands of Sentinel-2 in addition to calculated indices used in LULC like Blue Ratio (BR), Vegetation index based on Red Edge (VIRE) and Normalized Near Infrared (NNIR), etc. which gives a better accuracy of 99.58%.
