La explicación científica en profesores de Ciencias
Authors: Paredes Arturo Nayibe Mabel , García Martínez Álvaro
Published: January 2022

Este estudio analizó las explicaciones científicas dadas por un grupo de profesores de ciencias en ejercicio de educación básica secundaria. Se diseñó una investigación cualitativa e interpretativa con estudio de caso a partir del cual se identificó el perfil de las explicaciones que los docentes utilizan en el momento de enseñar los fenómenos científicos. Para el análisis de la información se utilizó el software ATLAS.ti (conjunto de herramientas para el análisis cualitativo de entrevistas y grupos focales) por medio del cual se diseñaron las redes semánticas que permitieron elaborar unas tablas para mostrar la presencia o ausencia, durante el tiempo de clase, de los comportamientos asociados a las categorías de análisis. Los resultados mostraron que las explicaciones realizadas por los docentes se caracterizan por la descripción de los fenómenos, por el modelo de explicación causal y por el uso del método científico. Se concluyó que esta actividad de enseñanza inherente a la práctica pedagógica cotidiana de los docentes se orienta por un proceso de comunicación unidireccional. Finalmente, se discutieron las implicaciones de la construcción de explicaciones en el ejercicio de la docencia y el impacto de esta práctica científica en la formación de los estudiantes.
Auguste Scheurer-Kestner. Contribución a la atomicidad del hierro
Authors: Wisniak Jaime
Published: January 2022

Se sabía que las sales normales de los óxidos superiores podían hacerse más o menos básicas y seguir siendo solubles. Auguste Laurent había postulado que un mismo cuerpo podía tener dos masas atómicas diferentes siempre que se tuvieran en cuenta las funciones que realizaba, por ejemplo, Fe2 (ferrosum = 28) y Fe4/ 3 (ferricum = 18,66). Scheurer-Kestner demostró que cuando el hierro se disuelve en ácido nítrico hasta la saturación, el resultado siempre es un nitrato de hierro básico y la basicidad depende de la concentración del ácido como sal férrica. Para demostrar la naturaleza hexatómica del hierro, Scheurer-Kestner preparó y determinó las propiedades de una variedad de poliácidos y aceto-nitratos férricos, y mostró que, aunque todos ellos estaban bien definidos y cristalizados, no se prestaban a la representación racional conservando el antiguo masa atómica del elemento.

Seismic and Wind Analysis of RCC Building with Different Shape of Shear Wall and Without Shear Wall
Authors: Bage Bayi
Published: January 2022

Abstract: ETABS Stand for Extended Three-Dimensional Analysis of Building systems. ETABS integrates every aspect of the engineering design process. In the present situations of construction industry, the buildings that are being constructed are gaining significance, in general those with the best possible outcomes which are referred to members like beams and columns in multi storeys R.C structures. This paper deals with the seismic analysis of regular B+G+26 story building with shear wall and G+B+10 Story building with different irregular shapes considering different shapes of shear wall at different locations has been carried out. Which can be done in ETABS taking all the considerations regarding codes and other factors into account. All the buildings were analyzed with the same method as stated in IS 1893-Part-1:2016. The effect of shear walls on lateral capacity of the building are examined because the seismic analysis of a frame depends upon the location and symmetry of shear wall. Present study shows the shear wall improves not only the lateral stiffness and strength capacity but also the displacement capacity of structure. Comparison of results been done of different models by comparing the parameters such as story drift, story displacement, story stiffness and base reaction. Therefore, as far as possible irregularities in a building must be avoided. But, if irregularities have to be introduced for any reason, they must be designed properly following the conditions of IS 13920:1993. The complex shaped buildings are now days getting popular, but they carry a risk of sustaining damages during earthquakes.

Optimal Operation of Automotive Electrical System with Photovoltaic Generation and Three-level Battery Management Scheme
Authors: Mohan Dr. T Murali
Published: January 2022

Abstract: For many years, the electrical power requirements in Automotive Electrical System (AES) have been quickly increasing and are predicted to continue to climb. This trend is being pushed by the introduction of a slew of new vehicle features. The constant growth in power needs is stretching the limitations of current automotive power generation and control technologies, stimulating the development of higher-power and higher-voltage electrical systems and components. Electrical power on a vehicle is not free. It comes as a direct result of consuming fuel within the engine to drive the alternator. With a typical engine efficiency of 44% and with present fuel costs this leads to onboard electrical power costs 4 times more than a typical household utility rate. Global oil and gas resource depletion, as well as environmental concerns, have prompted the automobile industry to build more efficient and eco-friendly cars in order to minimize fuel use and safeguard the environment. In our proposed Automotive Electrical system configuration, we have an AES system which is powered by an automotive alternator and battery combination where the alternator is driven by an IC engine and we have a hybrid energy system using a Rooftop PV array with a battery management system (BMS). We discovered that during the off state, the whole load of the automobile is dependent on the 12Vlead acid battery for power, which causes the SOC to drop dramatically. As a result, the suggested model will include a flexible thin-film solar PV module positioned on the rooftop, which will be supported by a Maximum Power Point (MPPT) Tracking charge controller and will deliver energy to recharge the extra battery and meet the electrical requirements when the vehicle is stationary. When the vehicle is in motion, the existing alternator in the car's electrical system takes over the battery charging requirements, by this way, we can meet the electrical requirements of AES without running the engine for a long time by consuming fuel. The proposed model specialty is investigated using MATLAB/Simulink and compared with existing methods. Keywords: Automotive Electrical System (AES), Internal Combustion Engine (ICE), Hybrid Energy System, Rooftop PV array, Maximum Power Point Tracking (MPPT).

“Los ídolos siguen deambulando”: relectura de dos procesos de extirpación de idolatrías en el suroccidente de la provincia de Tunja (1595)
Authors: Alvarez Tobos Martín Ernesto
Published: January 2022

En agosto y octubre de 1595, el oidor Egas de Guzmán visitó las encomiendas de Lenguazaque e Iguaque. En el desarrollo de ese procedimiento, encontró que los muiscas seguían practicando sus rituales ancestrales, los cuales fueron calificados como idolatrías. A partir de esa designación se desencadenó su persecución; a la vez, fueron exhibidos los cambios que venía experimentando la autoridad de los caciques. El objetivo de este artículo es analizar cuatro aspectos que se manifestaron en esos procesos: la identificación como delito y pecado sobre esos cultos, las tensiones políticas alrededor de los caciques y capitanes en sus comunidades, el desarrollo de una “cohabitación religiosa” entre el catolicismo y las ceremonias ancestrales, y los tipos de castigos impuestos a los acusados.

Authors: Hestiningsih Retno , Syahputra Govinda Restu , Martini Martini , Yuliawati Sri , Wuryanto M. Arie , Diyana Sutra , Purwantisari Susiana
Published: January 2022

Sendangmulyo Village is one of the DHF (Dengue Hemorrhagic Fever) endemic areas in Semarang City. Previous studies reported that Aedes spp. active biting at night (nocturnal biting activity) in some areas in Indonesia. This indicates that changes in the blood-sucking behavior of Aedes spp mosquitoes can have an impact on dengue transmission. This research is a descriptive study with a cross-sectional study design. The study was conducted in 64 houses. The mosquito field collection was carried out using the resting mosquito collection method at 18.00-06.00 WIB. Observations of environmental parameters were also carried out to determine the temperature and humidity of the environment around the breeding grounds of Aedes spp. The results showed that there was a change in Aedes spp's blood-sucking activity from 16.00-17.00 WIB to 18.00-20.00 WIB. The distribution of Aedes albopictus in Sendangmulyo Village was 18% of the total Aedes spp. mosquitoes collected with a Resting Rate (RR) value of 0.98%. The average temperature and humidity in the area were 28.6 °C and 77.2%, respectively. This change in blood-sucking activity in Aedes spp has the potential to increase the risk of spreading DHF in Sendangmulyo Village. Dengue Hemorrhagic Fever vector control efforts need to be improved.

Abstrak

Kelurahan Sendangmulyo merupakan salah satu daerah endemis DBD (Demam Berdarah Dengue) di Kota Semarang. Studi-studi sebelumnya melaporkan bahwa Aedes spp. aktif menggigit pada malam hari (aktivitas menggigit nokturnal) di beberapa daerah di Indonesia. Hal ini mengindikasikan adanya perubahan perilaku menghisap darah nyamuk Aedes spp. dapat berdampak pada penularan dengue. Penelitian ini merupakan penelitian deskriptif dengan desain studi cross sectional. Penelitian dilakukan pada 64 rumah. Koleksi lapangan nyamuk dilakukan dengan metode  koleksi nyamuk istirahat  pada pukul 18.00-06.00 WIB. Pengamatan parameter lingkungan juga dilakukan untuk mengetahui suhu dan kelembaban lingkungan disekitar tempat perkembangbiakan Aedes spp. Hasil penelitian menunjukkan adanya perubahan aktivitas menghisap darah Aedes spp dari pukul 16.00-17.00 WIB menjadi pukul 18.00-20.00 WIB. Sebaran Aedes albopictus di Kelurahan Sendangmulyo adalah  18% dari total nyamuk Aedes spp yang terkoleksi dengan nilai Resting Rate (RR) sebesar 0,98%. Rata-rata suhu dan kelembaban di daerah tersebut masing-masing adalah 28,6 °C dan 77,2%. Perubahan aktivitas menghisap darah pada Aedes spp ini berpotensi meningkatkan risiko penyebaran DBD  di  Kelurahan Sendangmulyo. Upaya pengendalian vektor DBD perlu ditingkatkan.

Authors: Saragih Jef Rudiantho , Sahara Ratna , Harmain Ummu
Published: January 2022

Pangan merupakan kebutuhan paling utama bagi setiap manusia untuk dikonsumsi setiap harinya untuk aktif dan produktif secara berkelanjutan. Tujuan penelitian ini adalah untuk menganalisis pengaruh luas areal panen padi, jumlah penduduk, dan ketersediaan beras tahun sebelumnya terhadap ketahanan pangan.  Ukuran ketahanan pangan dalam penelitian ini menggunakan rasio ketersediaan beras, yaitu Rasio Konsumsi Normatif per kapita terhadap Ketersediaan Beras. Penelitian dilakukan di Kabupaten Simalungun pada bulan Pebruari sampai bulan April tahun 2020.  Data yang  digunakan adalah data sekunder yang diperoleh dari Badan Pusat Statistik (BPS) Kabupaten Simalungun dan Provinsi Sumatera Utara; Dinas Ketahanan Pangan, Perikanan dan Peternakan Kabupaten Simalungun dalam periode tahun 1988-2018.  Data dianalisis secara deskriptif dan regresi linier berganda. Rasio ketersediaan beras rata-rata di Kabupaten Simalungun pada tahun1988-2018 adalah 0,41.  Dengan surplus rata-rata 225.856 ton per tahun, ketahanan pangan (beras) Kabupaten Simalungun berada pada status surplus  tinggi.  Luas areal panen padi berpengaruh negatif dan tidak signifikan terhadap ketahanan pangan; yang berarti bahwa penambahan luas lahan areal panen padi akan menurunkan rasio ketersediaan beras.  Penurunan rasio ketersediaan beras berarti meningkatkan ketahanan pangan.  Jumlah penduduk berpengaruh positif dan tidak signifikan terhadap ketahanan pangan; dimana pertambahan penduduk akan menaikkan rasio ketersediaan beras.  Meningkatnya rasio ketersediaan beras berarti menurunkan ketahanan pangan. Ketersediaan beras tahun sebelumnya berpengaruh negatif dan sangat signifikan terhadap ketahanan pangan; dimana peningkatan jumlah ketersediaan beras tahun sebelumnya akan menurunkan nilai rasio ketersediaan beras. Dengan kata lain, ketersediaan beras tahun sebelumnya berperan positif dan signifikan terhadap ketahanan pangan. Hasil penelitian ini memberikan implikasi sekaligus rekomendasi bahwa diperlukan pengendalian laju alihfungsi lahan sawah, peningkatan produktivitas padi sawah dan padi ladang; pengendalian jumlah penduduk, diversifikasi pangan pokok; yang pada gilirannya akan meningkatkan ketersediaan beras tahun sebelumnya dan meningkatkan rasio ketersediaan beras dan meningkatkan ketahanan pangan di Kabupaten Simalungun.

Exit strategy of COVID-19 crisis and pathways of Vaccination
Authors: Roy Indrani
Published: January 2022

There is a strong coordinated effort by vaccination groups all
over the world to put an end to the current crisis of COVID-19. The Mass
vaccination first started in the UK on 8th December 2020 and soon
afterward covered all of the globe. Now sufficient data are available to
analyse and compare some results to explore many aftereffects of
vaccination. Some influence variables on transmissions of the disease
were discussed e.g., mass vaccination, lockdown and seasonality. To
address seasonality, similarities between COVID-19 and seasonal Flu are
discussed to gain useful insight. Like Flu, seasonality was shown to
play a dominant role in transmissions of COVID-19 in the Eu-rope and US.
In terms of mass vaccination, adverse reactions after vaccination
received attention, as health and safety issues of the general public
are of prime importance. Apart from direct side effects, the secondary
effect of mass vaccination needs attention too. After the initiation of
vaccination programme , almost all countries experienced a sudden surge
of transmission and most countries had to impose strict lockdown
measures. Many countries, those showed a low prevalence of the disease,
suddenly showed a steep jump after the onset of mass vaccination. Some
countries even followed a synchronized pattern between the rate of
transmissions and the variation of vaccine doses; the pattern seemed
distinct with the sudden steep rise/fall in vaccine doses (e.g.,
countries India, Indonesia among others). In that context, fast mutation
of the virus and new variants after mass vaccination and possible
mechanisms/consequences were discussed.

Balanced discussion, critical and open analyses
are desperately needed in the current crucial stage. Debating,
questioning and criticism are always the foundation of good science and
the main pillars to its progress. Following that objective, it is an
effort to explore pragmatically, areas relating to the effectiveness of
the COVID-19 vaccine and the exit strategy via the pathway of
vaccination. Policymakers, academics, patients and common people will be
greatly benefitted from such critical, transparent and balanced
analyses.
Obesity-Induced miR-455 Upregulation Promotes Adaptive Pancreatic β-cell Proliferation Through the CPEB1/CDKN1B Pathway
Authors: Admin Ada , Hu Qianxing , Mu Jinming , Liu Yuhong , Yang Yue , Liu Yue , Pan Yi , Zhang Yanfeng , Li Ling , Liu Dechen , Chen Jianqiu , Zhang Fangfang , Jin Liang
Published: January 2022

Pancreatic β-cell adapt to compensate for increased metabolic demand
during obesity. Although the microRNA (miRNA) pathway has an essential
role in β-cell expansion, whether it is involved in adaptive
proliferation is largely unknown. First, we report that EGR2 binding to
the miR-455 promoter induced miR-455 upregulation in the pancreatic
islets of obesity mouse models. Then, in vitro gain- or loss-of-function
studies showed that miR-455 overexpression facilitated β-cell
proliferation. Knockdown of miR-455 in ob/ob mice via pancreatic
intraductal infusion prevented compensatory β-cell expansion.
Mechanistically, our results revealed that increased miR-455 expression
inhibits the expression of its target cytoplasmic polyadenylation
element binding protein 1 (CPEB1), an mRNA binding protein that plays an
important role in regulating insulin resistance and cell proliferation.
Decreased CPEB1 expression inhibits elongation of the poly-A tail and
the subsequent translation of Cdkn1b mRNA, reducing the CDKN1B
expression level and finally promoting β-cell proliferation. Taken
together, our results show that the miR-455/CPEB1/CDKN1B pathway
contributes to adaptive proliferation of β-cells to meet metabolic
demand during obesity.
Global Kidney Health Atlas: a spotlight on the Asia-Pacific sector
Authors: Bharati Joyita , Jha Vivekanand
Published: January 2022

Chronic kidney disease (CKD) is a unique public health problem in terms of high expenses required for its management and its increasing worldwide incidence. Understanding the existing structure of CKD treatment and its epidemiology is pivotal for equitable kidney care globally. The Global Kidney Health Atlas (GKHA) was launched by the International Society of Nephrology (ISN) in 2017 as a part of its “Bridging the Gaps” strategy with a vision to understand the global kidney care capacity. Two rounds of GKHA surveys were conducted and published in 2017 and 2019, respectively. The GKHA surveys showed significant variability in kidney care among global regions. Asia is the largest of all continents and distinct for its heterogeneity. The Asia-Pacific sector comprises four main regional constructs of the ISN; North and East Asia, Oceania and South East Asia, South Asia, and the Middle East. Kidney care capacity varies among these regions in terms of government spending, epidemiology of kidney diseases, and workforce availability. In this narrative review, we highlight the differences in kidney care delivery among the regions of the Asia-Pacific sector based on information from GKHA and emphasize the priority areas on which stakeholders should concentrate their efforts.
Prognostic Indicator in Severe Acute Pancreatitis
Authors: Khanolkar Dr. Ajay , Khare Dr. Manish
Published: January 2022

Aim of study: - To assess the utility of each as prognostic indicator in Severe Acute Pancreatitis.

Material and Methods: This prospective study entitled “To assess the utility of each as prognostic indicator in Severe Acute Pancreatitis” was carried out on patients hospitalized for acute pancreatitis in the surgery department at Chandulal Chandrakar Memorial Medical College and CM Hospital, Bhilai from March 2015 to October 2017.50 patients with the diagnosis of first attack of acute pancreatitis of both sexes and all age groups were selected for the study.

Conclusion:- On the basis of observation and result of the study, it can be safely stated that APACHE II Scoring is quick, safe, reproducible, ongoing and cost effective. It can be done by resident or intelligent nursing staff. Give an idea regarding improving or worsening of patients.

APACHE II Scoring system when complimented by high quality CECT abdomen can further refine the results and give an idea of likelihood of patients developing local complication. Thus it can also be used along with CECT abdomen for Risk Stratification of subset of patients who are likely to develop local complication who might need surgical intervention.

CECT on 3rd day adds nothing to management. It has a tendency to over predict the regional complication, which are in anyway apart of natural course of history of disease (acute fluid collection). Management decision could not be based on CECT abdomen on 3rd day alone, since it is not needed to make a diagnosis of acute pancreatitis it should be abundant, thus reducing the financial burden of patients and institute. CECT abdomen done after 2nd week in the course of illness along with APACHE II Score and clinical finding are better guide for management and surgical intervention.

Oposisi Biner dalam “Lettres de Mon Moulin” Karya Alphonse Daudet
Authors: Everina Rifqi Ayu
Published: January 2022

Binary opposition is the most important aspect that can reveal how humans think, how humans produce meaning and understand reality (Culler, 1976). Therefore, the discovery of binary oppositions is useful in providing clues to the workings of human reason. In the context of narrative analysis, binary opposition can reveal how the logic behind a narrative is made. Based on this, this study highlights how the formation of binary opposition contained in the novel "Lettres de Mon Moulin" by Alphonse Daudet uses Lévi Strauss's theory of binary opposition (1955) and structural analysis using Freytag's plot theory (1863). The corpus of the research consists of six stories contained in the novel forming a binary opposition. After doing the analysis, it was found that a pair of words with binary opposition were included in the exclusive category and two pairs of words that were included in the non-exclusive binary opposition category. From these findings, it was found that the author of the novel, Daudet, gave directions on what was good and bad by giving a clear line of separation. This is in line with the context of making stories during the industrial revolution, which mapped the world into two things, namely traditional and modern life.

Foreign Language Lexicons Used in Indonesian Housing Names: A Peircean Semiotics Overview
Authors: Hadiati Chusni
Published: January 2022

Abstract: Housing belongs to human basic need since to live properly they need a place to stay. Housing names in Indonesia employ not only Bahasa Indonesia but also foreign language because some foreign lexicons are used in Indonesian housing names. Semiotically, names are symbols that carry meaning in certain context. Indonesian housing names are interesting language phenomena since they reveal the use of language as a social praxis. Legally, the use of language in public space is governed by Indonesian Law No.24, Year 2009 on flag, language, national symbols, and national anthem. In fact, Indonesian housing names do not fully follow the law because foreign language lexicons are also used in Indonesian housing names. This research employed 2000 Indonesian housing names and collected during January 2017 until May 2017. Data indicated that there were lexicons from three foreign languages, namely, English, Spanish, and Arabic. This research belongs to descriptive qualitative research. In-depth interview was also utilized to gain deeper information why developers use certain lexicons. Developers believed that names are supposed to be beneficial and bring luck. Using Peircean semiotic, this qualitative research reveals that  lexicons used in Indonesian housing names are used to show place name (Baturraden, Citayam, Batam, Surabaya), settlement (cassa, village, residence, estate, city, garden, hill, valley, river, lake), greatness (grand, grande, great, royal, big), positivity (blossom, lucky, oase, firdaus, sakinah, paradise), preciousness (emerald, platinum, diamond, golden, stone), environmental awareness (green color), purity (white color, jasmine), warmth (red rose), and love (red color, orchid, lily, tulip).

Right axis deviation in the canine electrocardiogram for predicting severity of pulmonic stenosis: a retrospective cohort analysis
Authors: Ackerman Leah H. , Reynolds Penny S. , Aherne Michael , Swift Simon T.
Published: January 2022

OBJECTIVE

To investigate the predictive value of right axis deviation of the mean electrical axis (MEA) in assessing the severity of pulmonic stenosis (PS) in dogs.

ANIMALS

Records for 218 client-owned dogs diagnosed between 2014 and 2020 with PS as determined by Doppler echocardiography.

PROCEDURES

University of Florida Small Animal Clinic medical records were reviewed, and signalment and clinical risk variables (murmur grade and clinical signs) were extracted. MEA was determined from ECG records by use of leads I and III. Predictive potential of MEA and associated risk factors to diagnose PS severity (mild [< 50 mm Hg], moderate, or severe [> 75 mm Hg]) were assessed by receiver-operating characteristic curve analysis and quantile regression.

RESULTS

Records for 88 dogs were eligible for analysis. Greater PS severity was associated with smaller breeds presenting with ECG abnormalities, overt clinical signs, and high-category murmur grades (IV and V). Mean MEA increased with stenosis severity category, with an average of 62° for mild, 113° for moderate, and 157° for severe. Each 10° increase in MEA corresponded to an approximately 5–mm Hg increase in PG. Increasing PS severity was associated with MEA right axis deviation > 100° and the more severe cases (PG > 75 mm Hg) with MEA right axis deviation > –180°.

CLINICAL RELEVANCE

Mean electrical axis right axis deviation may be a useful screening metric for dogs with suspected moderate to severe PS.

Потенциал функционирования платежно-расчётной системы в рамках ЕАЭС и обращения коллективной валюты
Authors: Жариков М. В.
Published: January 2022

Жариков М. В.  Потенциал функционирования платежно-расчётной системы в рамках ЕАЭС и обращения коллективной валюты. Тема исследования актуальна в связи с эскалацией международных санкций в отношении России и вероятностью её исключения из расчётной системы SWIFT. Поскольку другие страны ЕАЭС находятся в сильной зависимости от России в сфере внешней торговли, инвестиций, обмена технологиями, транспорта, энергетики и т.д., подобные санкции оказывают существенное дестабилизирующее влияние и на них. С учётом этих тенденций и зарубежного опыта автор делает попытку сформулировать основные элементы и направления создания независимой системы расчётов стран ЕАЭС с оценкой перспектив использования коллективной валюты, повышения уровня независимости экономик от колебаний мировых цен, преодоления зависимости от доллара. Ключевые слова: платежная система ЕВРАСЧЁТ-24, коллективная региональная валюта ЕАЭС, межстрановая дивергенция, факторы и условия валютно-финансовой интеграции, барьеры интеграции
Some Clinical and Inflammatory Aspects of Trichomonas vaginalis Infection among Women with Pelvic Inflammatory Diseases
Authors: Abdul Jabbar Zainab Rasheed , Al-warid Harith Saeed
Published: January 2022

Infection with Trichomonas vaginalis and its relation to some diseases have lately had much attention.  The objective of this study was to assess the infection rate of T. vaginalis and its relation to pelvic inflammatory diseases, infertility, and vaginosis. The study also assessed some demographic, clinical, and immunological parameters in women infected with T. vaginalis. The study included 160 non-pregnant married women who attended some private clinics and public hospitals in Baghdad from October 2020 to February 2021. All participants had symptoms of vaginal discharge only or vaginal discharge with lower abdominal pain. The participants were divided into an infertility group (n = 61) and fertility group (n = 99). The participants were also divided into Pelvic Inflammatory Disease (PID) group (n=41) and non-PID group (n=119). All participants underwent vaginal examination. Vaginal swabs were taken from all participants for T. vaginalis, bacteria, yeast, clue cell, pH, and vaginal leukocyte examinations. Sera were also taken to measure both IL-1α and IL-8 using sandwich ELISA technique to compare them with apparently healthy control subjects who had no vaginal discharge. The study revealed that the total infection rate of T. vaginalis was 14.37%. The results showed no significant relations  between T. vaginalis positive status and each of age, infertility, vaginosis, contraceptive use, and high BMI. While a significant relation (P=0.03) was noticed between T. vaginalis positive status and PID. Women with PID exhibited a higher infection rate with T. vaginalis (24.39%) versus non PID women (10.92%). High clue cells number was not significantly related to T. vaginalis positive status, only if both PID and vaginosis were considered in the statistical analysis. In addition, high leukocytes count was not related to T. vaginalis positive status. While abnormal vaginal pH was significantly (P=0.01) related to T. vaginalis positive status. Finally, the levels of both IL-1α and IL-8 were noticed to be declined in women who had T. vaginalis infection, although they were not declined significantly. This study gives an insight about some clinical aspects of T. vaginalis infection among PID women. T. vaginalis is highly predictable in women with PID. Consequently, attention and more investigation would be needed on this topic in Iraq.
