Grupos de autoconocimiento en el movimiento para la salud de las mujeres durante la transición política española
Authors: Rebolledo Alba Martínez
Published: September 2020

Aproximación a la historia el movimiento de salud de las mujeres y del movimiento self-help en el Estado español durante los años 1976 a 1985. Esta perspectiva, con una marcada intención educadora, se centraba en la transformación de la vida de las mujeres a través del autoconocimiento del cuerpo y el cuestionamiento del conocimiento médico. Tuvo gran influencia en colectivos feministas que percibían la necesidad de liberación de las mujeres a través del cuerpo, pero también en otros ajenos al feminismo pero de carácter progresista. Veremos el contexto de sus inicios en EE.UU. y cómo se traslada y difunde en nuestro país durante la Transición política española. Conoceremos su desarrollo a lo largo de esos años y los principales colectivos que se enmarcan en esta perspectiva hasta 1985, cuando se produce un cambio sustancial en el activismo en su conjunto debido a la institucionalización de la agenda feminista.
Elementos para la despolitización del cáncer de mama
Authors: Porroche-Escudero Ana
Published: September 2020

El cáncer de mama ha cobrado una visibilidad sin precedentes en el Estado español. Tras unos orígenes preocupados por el carácter opresivo del rol de la paciente y los determinantes sociales de la incidencia del cáncer, las últimas tres décadas se han caracterizado por una preocupación con el diagnóstico temprano de la enfermedad a través de programas de cribado y de campañas solidarias de concienciación. A priori parece que habría que festejar esta politización progresiva del cáncer de mama que lo ha puesto en la agenda nacional. En este articulo argumento que lo político ha entrado en crisis, despolitizando la enfermedad sin tan apenas levantar sospechas entre los sectores más críticos del país, incluido el feminista. Retomo la crítica de la ‘sobreinvisibilización’ del cáncer de mama de la antropóloga vasca Mari Luz Esteban (2017) para demostrar cómo nos encontramos en una situación en la que la premisa ‘el fin justifica los medios’ ha colonizado el pensamiento colectivo. Esta colonización limita la capacidad de las instituciones, personas, organizaciones, profesionales y corporaciones de hacer autocrítica. No planteamos cuestiones entorno a qué temas se abordan, cómo se habla de la enfermedad, cómo se representa a las mujeres y qué temas permanecen silenciados o tabú. Para ilustrar la despolitización presentaré ejemplos de los dos elementos que componen la sobreinvisibilización: los discursos y prácticas sobre el cáncer de mama hipervisibles y aquellos que son invisibilizados. Los primeros son dominantes, monotemáticos y perpetúan mensajes androcéntricos. Los invisibilizados raramente llegan al ámbito público, principalmente porque cuestionan el estatus quo de la industria del cáncer.

Preheating of Gelatin Improves its Printability with Transglutaminase in Direct Ink Writing 3D Printing
Authors: Tan Justin Jia Yao , Lee Cheng Pau , Hashimoto Michinao
Published: September 2020

Gelatin and transglutaminase (TG) ink is increasingly popular in direct ink writing three-dimensional (3D) printing of cellular scaffolds and edible materials. The use of enzymes to crosslink gelatin chains removes the needs for toxic crosslinkers and bypasses undesired side reactions due to the specificity of the enzymes. However, their application in 3D printing remains challenging primarily due to the rapid crosslinking that leads to the short duration of printable time. In this work, we propose the use of gelatin preheated for 7 days to extend the duration of the printing time of the gelatin ink. We first determined the stiffness of freshly prepared gelatin (FG) and preheated gelatin (PG) (5 – 20% w/w) containing 5% w/w TG. We selected gelatin hydrogels made from 7.5% w/w FG and 10% w/w PG that yielded similar stiffness for subsequent studies to determine the duration of the printable time. PG inks exhibited longer time required for gelation and a smaller increase in viscosity with time than FG inks of similar stiffness. Our study suggested the advantage to preheat gelatin to enhance the printability of the ink, which is essential for extrusion-based bioprinting and food printing.
Comparing the efficacy and haemodynamic response between intrathecal hyperbaric 0.5% bupivacaine with isobaric 0.75% ropivacaine using fentanyl as adjuvant in patients undergoing infra umbilical surgeries
Authors: Kumar R Arun , Preetha I
Published: September 2020

Central neuraxial blockade is the most widely used form of regional anesthesia in surgeries involving abdominal, urological, obstetric, gynaecological and lower limb. The nerve blocking properties of the R and S-enantiomers were similar but that the S-enantiomer was less cardiotoxic. The aim of our study is to compare the efficacy and haemodynamic response between intrathecal hyperbaric 0.5% Bupivacaine with isobaric 0.75% Ropivacaine using Fentanyl as adjuvant in patients undergoing infra umbilical surgeries.

60 patients of age group between 25 – 65 years belonging to American Society of Anaesthesiologist (ASA) 1 and 2 posted for general surgical, urological, orthopaedic and gynaecological procedures involving lower abdominal surgeries under spinal anaesthesia divided into two groups of 30 each and randomly allocated to one of the two below mentioned groups:

Bupivacaine group (Group B) n=30; Ropivacaine group (Group R) n=30

Chi-square test and Student’s ‘t’ test were used to analyse the results. The sensory block in Bupivacaine group B was significantly higher compared to Ropivacaine group R attaining statistical significance. The 3 minutes motor block, incidence of hypotension was denser and higher in Bupivacaine group compared with Ropivacaine group. Incidence of bradycardia was not significantly different between the two groups.Although the onset of motor blockade was denser in Bupivacaine group, the total duration of motor blockade was similar between the groups.

We conclude from our study that 0.75% isobaric Ropivacaine produces similar duration of efficacy with stable haemodynamics, as compared with 0.5% hyperbaric Bupivacaine.

Published: September 2020

Spinal anesthesia is a preferable technique for lower abdominal surgeries as it provides effective sensory and motor block with rapid onset, attenuation of stress response and less thromboembolic episodes. It is currently known that levobupivacaine and racemic bupivacaine have similar analgesic potencies for epidural and spinal anesthesia. Due to the adverse cardiac effects of racemic bupivacaine, several studies have been performed in order to find anesthetic compounds to take its place.

To compare and evaluate the efficacy between 0.5% isobaric Levobupivacaine and 0.5% racemic Bupivacaine in spinal anesthesia among the patients undergoing lower abdominal and lower limb surgeries.

A prospective comparative study was conducted for a period of one year at our hospital under the department of anesthesia. Based on purposive sampling 200 subjects were selected for the study and were divided into two groups. The study subjects were randomly allocated into two groups of 100 each. Group B subjects received 3ml of 0.5% intrathecal hyerbaric Bupivacaine (15 mg) and group L patients received .5% intrathecal Isobaric Levobupivacaine (15 mg). The mode of onset and the duration of motor and sensory block were assessed and the subjects were monitored for blood pressure, peripheral oxygen saturation (SpO2), and pulse rate at 1st, 3rd, and 5th min and every 5 min up to the 30th min, and then every 10 min until the end of the operation.

The onset and the duration of motor and sensory block did not show statistical significant difference between the bupivacaine and levobupivacaine. The incidence of hypotension and bradycardia was more among the bupivacaine group than that of the levobupivacaine group and the difference was found to be statistically significant (p<.05), whereas the incidence of nausea, vomiting or respiratory depression did not show a statistical significant difference between the two groups.

Levobupivacaine with the same potency and lesser cardiovascular side effects could be considered as a better alternative for bupivacaine.

Authors: S Anusha , Ajjapa Arun Kumar
Published: September 2020

Post operative sore throat(POST), cough and hoarseness of voice though minor sequelae after tracheal extubation can be distressing to the patients, and is not an uncommon complaint, it adversely affects the patient satisfaction and activities after discharge.

A comparative study was conducted to see the incidence of post operative sore throat after tracheal extubation after applying betamethasone gel(Group 1) and KY jelly(Group2) on the cuff of the tracheal tube in patients undergoing elective surgery under general anaesthesia. POST was assessed at rest and with efforts like swallowing and talking at 1, 3, 6, 12, 24 hrs post operatively.

The incidence of POST was significantly lower in the betamethasone group when compared to KY jelly group.

From our study we can conclude that application of betamethasone gel on the cuff of ETT decreases the incidence of POST after tracheal extubation. Severity of sore throat is assessed using VAS score and found that POST was severe in ky jelly group when compared with betamethasone group.
Podstawy prymatu oraz misja Biskupa Rzymu według kardynała Gerharda L. Müllera
Authors: Artemiuk Przemysław
Published: September 2020

Pytanie o miejsce i rolę papieża w Kościele katolickim bardzo wyraźnie pojawia się w myśli teologicznej kard. G.L. Müllera (ur. 1947). Niemiecki hierarcha, podejmując refleksję nad tym zagadnieniem, czyni to w sposób uporządkowany i systematyczny, łącząc wątki dogmatyczne ze spojrzeniem fundamentalnoteologicznym. Papiestwo, zdaniem G.L. Müllera, jest faktem historycznym, który posiada swoje źródło w tajemnicy Objawienia. Podejmując refleksję nad tym zagadnieniem, obecnym w myśli teologa, autor odwołuje się do jego kluczowych tekstów, przede wszystkim do pracy Der Papst. Sendung und Auftrag opublikowanej w roku 2017, a także do wypowiedzi zawartych w tomie rozmów, jakie z kardynałem przeprowadził red. Paweł Lisicki. W prezentowanym artykule autor ukazuje najpierw interpretację klasycznych tekstów prymacjalnych, proponowaną przez kard. Müllera. Następnie omawia najwcześniejsze świadectwa Tradycji, do których odwołuje się niemiecki teolog. W końcu zwraca uwagę na misję, jaka wypływa z papieskiego urzędu. W zakończeniu wyciąga wnioski w perspektywie eklezjologii fundamentalnej.
Nieomylność Biskupa Rzymu jako problem eklezjologiczny ad intra i ad extra
Authors: Żmudziński Marek
Published: September 2020

Artykuł przedstawia problem nieomylności papieskiej w debacie eklezjologicznej wewnątrz Kościoła katolickiego oraz w kontekście dialogu ekumenicznego, prowadzonego z innymi wyznaniami chrześcijańskimi. Punktem wyjścia jest wyjaśnienie tego pojęcia oraz główne zagadnienia zawarte w dogmacie o nieomylności Biskupa Rzymu, ogłoszonym na Soborze Watykańskim I. Istota kontrowersji, które pojawiły się już w trakcie obrad Vaticanum I oraz po jego zakończeniu, polegała na ukazaniu relacji nieomylności Kościoła i nieomylności samego papieża: czy następca Piotra jest niezależny w definiowaniu prawd wiary. Brak konsensusu doprowadził do schizmy i powstania Kościoła starokatolickiego i ekskomuniki wielu teologów. Współcześnie nieomylność papieska jako problem eklezjologiczny obecna jest w dialogu ekumenicznym, w którym poszukiwana jest nowa jej formuła.
Joseph Ratzinger’s Idea of Ecumenical Dialogue in Truth: Inspirations, Questions, and Problems
Authors: Kaucha Krzysztof
Published: September 2020

Josepha Ratzingera koncepcja dialogu ekumenicznego w prawdzie: inspiracje, pytania i problemy

Niewątpliwie Joseph Ratzinger jest jednym z najbardziej kluczowych uczestników dialogu ekumenicznego nie tylko dlatego, że piastował najważniejsze funkcje w Kościele katolickim. Wiele jego dzieł jest poświęconych problematyce ekumenicznej. Niniejszy artykuł jest efektem badań podjętych nad całą jego twórczością, które od 2018 r. są w całości dostępne w języku polskim. Jednym z rezultatów tych badań jest stwierdzenie, że Ratzinger posiada oryginalną koncepcję dialogu ekumenicznego. Jest ona w tym artykule nazwana ,,dialogiem ekumenicznym w prawdzie”, choć jest bardziej znana jako ,,droga do jedności w różnorodności”. Jej charakterystyka wypełnia pierwszą część artykułu. Ratzinger uważa, że należy zgodnie z prawdą nazwać przyczyny podziałów w chrześcijaństwie. Trzeba dzięki prawdziwemu dialogowi z Panem uznać, że podziały mogą być przez Niego dopuszczone dla wyższego dobra. Należy wyraźnie zobaczyć pragnienie prawdziwej wierności Panu u korzeni wielu podziałów oraz ,,być pokornym i cieszyć się osiąganiem realistycznych pośrednich celów” w dialogu ekumenicznym. Ratzinger proponuje, by uznać jako prawdziwe chrześcijaństwo liczne osiągnięcia wypracowane przez różne chrześcijańskie Tradycje w ciągu wieków. Druga część artykułu jest poświęcona nowym inspiracjom oraz pytaniom i problemom, które rodzi koncepcja Ratzingera dla teologii fundamentalnej. Ta teologia nie może przejść obok niej obojętnie, bowiem Ratzinger porusza kluczowe dla teologii fundamentalnej zagadnienia, na przykład rozumienie chrześcijaństwa, jego autentyczności i prawdziwości, tożsamości i istoty, rozumienie Kościoła oraz pojęcia ,,wiarygodność”. Jego koncepcja rodzi konieczność dokonania korekt w katolickiej teologii fundamentalnej co do jej głównych założeń, zadań, nastawienia względem chrześcijan niekatolików, pojęć i metod.

Authors: Primadata Ankarlina Pandu , Biroli Alfan
Published: September 2020

Education is a right for every individual, but sometimes not everyone can get the education as expected. Forest edge communities residing in Pesawahan Hamlet, Gunung Lurah Village, Banyumas Regency are examples of people who cannot enjoy the beauty of education properly. The condition of remote areas, with access to transportation that is quite difficult, and the absence of telecommunications signals increasingly makes it difficult for forest edge communities to obtain proper education. MTs Pakis is a school that was built in the area of Pesawahan Hamlet as an effort to provide better education services for forest edge communities. The school has two methods of education and learning, namely formal education and learning methods and agroforestry education and learning methods. The agroforestry education method is carried out because of the condition of students who must continue to help their parents in the fields and rice fields even though they attend school. With agroforestry education, students not only receive subject matter indoors, but also gain expertise and skills related to agriculture and animal husbandry. This is done so that students get provisions for their daily lives.

A Review of Silorane and Methacrylate Based Composites and Effective Factors on Microleakage of them
Authors: Daneshkazemi Alireza , Ersi Mahnaz
Published: September 2020

Introduction: An important disadvantage of current dental resin composites is their polymerization shrinkage and production of microleakage. This shrinkage can cause tooth sensitivity, marginal discoloration, and secondary caries. The objective of this study was to review the effective factors on microleakage of methacrylate and silorane composites and compare them with each other. This reviewed article was compiled and searched on library sources and Google scholar, Pubmed, ISI of science database, using the key words “Microleakage, Siloran-Based Composite, Methacrylate-Based Composite, Retentive Groove, Light Curing Technique,” from 1984 -2019. Although it is not yet definitely clear, which methods of layering techniques (oblique, vertical, split) are more suitable, it seems that the layering technique has advantage over the bulkythat can effective in decreasing the shrinkage caused by polymerization and the resulting microlaekage.  It can also be concluded that silorane base composites have less shrinkage, but some factors such as cavity type, cavity extent, cavity margin distance to CEJ, type of silorane base  bonding system are also involves in their microleakage.  It seems the presence of retention grooves in the cavities seems useful, because it increases the bonding area and mechanical retention as well as decreases the marginal shrinkage due to polymerization and the resulting microleakage.
Conclusion: Finally, it can be said that microleakage cannot be stopped completely, and more studies, especially clinical studies, should be conducted to show the effects of these cases clinically.
Hamartomatous Polyposis Syndromes: Management and Surveillance Strategies
Authors: Sedighi Sima , Jokar Mohammad Hassan , Moradzadeh Maliheh
Published: September 2020

Introduction: Hamartomatous Polyposis Syndromes (HPS) are a rare group of dominant autosomal inheritance, which is characterized by the development of hamartomatous polyps in the gastrointestinal tract. This syndrome included Juvenile Polyposis syndrome (JPS), Peutz-Jeghers syndrome (PJS), and PTEN Hamartoma Tumour Syndrome (PHTS). PTEN Hamartoma Tumour Syndrome (PHTS) itself includes Cowden Syndrome, Bannayan-Riley-Ruvalcaba Syndrome (BRRS), and Proteus Syndrome.Diagnosis of Hamartum polyarthritis syndrome (HPS) is routinely made based on clinical criteria, but sometimes the diagnosis of this syndrome becomes problematic due to the varying severity of clinical symptoms even within a family.Therefore, today, genetic testing of germ-related mutations associated with this disease is used in the diagnosis process. Management strategy of the syndrome is different due to extra-intestinal symptoms and various cancers. Clinical awareness and early diagnosis of HPS is important, so it is recommended to patients and families at risk for genetic counseling and care. Surveillance in children with HPS might prevent intestinal and extra-intestinal disorders, and reduce the risk of intestinal cancer or breast cancer in adults.

Introduction: Menopause can change the musculoskeletal system by reducing estrogen hormone levels. The aim of this study was to evaluate the effect of regular resistance training accompanied by vitamins D and calcium supplements during pre-menopausal period on muscle tissues of Wistar rats’ postmenopausal period.
Methods: In this experimental study, female Wistar rats were randomly divided into control, placebo, vitamins D, Calcium, excercise, vitamins D- Calcium, vitamins.D- excercise, Calcium - excercise, and vitamins.D‐ Calcium - excercise groups. Control and placebo groups were fed with a standard diet and sesame oil, respectively. The amount of calcium consumed was 35 mg / kg and the amount of vitamin D was 10000 IU during the two-month period, and in the resistance training groups, two months of training was performed with a ladder. Then ovariectomy was done and sample of the gastrocnemius muscle was taken and the diameter of muscle fiber, the number of muscle and adipocyte cell as well as the number of inflammatory cells were studied. The statistical analysis by means of one-way ANOVA and SPSS version 20 was performed.
Results: Compared to the control group, the increase in the number of adipocyte cells were observed in the vitamin D, calcium-vitamin D, vitamin D-resistance exercise and placebo groups but it was not significantly different. Muscle fiber diameter significantly increased in all groups compared to the control group (P <0.001). The number of muscle cells increased significantly in the calcium-resistance exercise group (103± 9), vitamin D-resistance exercise (105 ±6.9) and calcium-vitamin D-resistance exercise (114 ± 3.16) compared to the control group, while, there was a significant increase in inflammatory cells only in the control and placebo groups (p≤0.05).

Objective: To analyze the accuracy of frozen section (FS) examination of a borderline ovarian tumor (BOT) and the factors affecting it.Methods : We retrospectively evaluated 132 patients who were operated on in our clinic for ovarian mass between 1996 and 2016, who underwent FS examination and who had a BOT as a result of the final pathology. We investigated the Frozen accuracy, overdiagnosis and underdiagnosis rates and the factors affecting the accuracy of the diagnosis.Results : The mean age of the sample group was 44.6 ± 15.2 years. 50.8% of our patients were serous, 34.8% were mucinous and 14.4% were sero-mucinous in histology. Our Frozen Section accuracy rate was 75%, and underdiagnosis and overdiagnosis rates were 20.5% and 4.5%, respectively.The factors affecting the accuracy of the frozen section were histological type (p = 0.003), presence of solid component (p = 0.002) and preoperative CA 125 value (p = 0.001).Conclusion : Frozen examination has a low accuracy rate that affects the correct selection of surgical treatment for BOTs. FS should be performed by experienced gyneco-pathologists and it is necessary to consider carefully the factors that may cause misdiagnosis of the pathology.

We studied the population increment and enterprise increment under the policy of “building socialism with Chinese characteristics pilot demonstration zone” in Shenzhen and calculated the number of permanent residents and enterprises in Shenzhen in terms of short term (next year) and long term (next five to ten years). Combined with the new population and enterprises brought by the new economic policy and the model in question 1, the data of Shenzhen GDP in the short-term and long-term situations are calculated. So we concluded that the long-term impact on Shenzhen will be greater than the short-term impact in the future.

Application of Financial Sharing in Financial Management of Group Enterprises
Authors: Gan Linlin
Published: September 2020

Financial shared service is a new management mode established on the basis of financial system reform. Under this mode, independent financial organizations are stripped off and financial information of company’s branches is merged into financial shared service center. The center is responsible for simple and repetitive, common and standardized operations for each branch in order to realize the centralized management and accounting. It greatly improves the efficiency of enterprise management, reduces management costs, and improves customer satisfaction and the service quality. As a new emerging thing in financial management, financial shared service center has turned into reality rather than a concept, and there are more and more enterprises benefit from it. This new financial management model is emerging and being adopted by many multinational companies and large domestic enterprises.

Published: September 2020

The sudden outbreak of COVID-19 has brought great impact on China’s economic development. How to scientifically and effectively help the economy has become the most important economic issue at present. During the COVID-19 pandemic, the service industry has been directly affected, while small and medium-sized enterprises (SMEs) have also been seriously hit, and the negative impacts on export-oriented enterprises cannot be underestimated as well. It is critical and urgent for these enterprises to quickly recover from the crisis and find ways to secure a viable competitive position in their respective industries in post-pandemic era. The Coronavirus (COVID-19) pandemic has not only brought unprecedented impact on China’s economic and social development, but also provided new opportunities for traditional industries to achieve digital transformation. Taking service industry, foreign trade enterprises and small and medium-sized enterprises for example, this study focuses on how China’s industries and enterprises in the post-pandemic era can recover from the impact of the pandemic by taking advantage of digital transformation opportunities: (1) Transferring services online and promoting upgradation of online business; (2) Cooperating with e-commerce platforms to transfer exports to domestic sales and catering to the need of domestic consumers; (3) Applying flexible production and shared manufacturing to better cope with external changes and reduce operation costs of small and mediumsized enterprises. Fintech also helps to reduce financing costs.

Published: September 2020

La mediciÃ³n de la deformaciÃ³n de la corteza terrestre utilizando tÃ©cnicas basadas en Sistemas Globales de NavegaciÃ³n por SatÃ©lite (GNSS) fue una de las metodologÃ­as a utilizar en el proyecto Topo-Iberia. Concretamente se utilizÃ³ el Sistema de Posicionamiento Global (GPS) y se estableciÃ³ una red de veintisÃ©is estaciones operando continuamente (cGPS) en la PenÃ­nsula IbÃ©rica y norte de Ãfrica. Las redes GNSS requieren un control permanente para asegurarse de que las estaciones funcionan correctamente y que la calidad de sus datos son apropiados para estudios geodinÃ¡micos. En este trabajo se ha desarrollado y presentado por primera vez la monitorizaciÃ³n y control de calidad de las estaciones de la red Topo-Iberia que estÃ¡n a cargo de la Universidad de JaÃ©n. Se han descrito los procesos del control de calidad implementados en el Servicio GNSS del CEACTierra, abarcando desde la recuperaciÃ³n de datos GPS de las estaciones desplegadas en campo hasta su envÃ­o al Instituto GeolÃ³gico y Minero de EspaÃ±a (IGME), instituciÃ³n encargada de centralizarlos. Se ha estudiado la calidad de un periodo de casi once aÃ±os en el caso de estaciones activas y se han analizado los eventos acontecidos mÃ¡s significativos. El estudio manifiesta que los emplazamientos de estas estaciones son Ã³ptimos para conformar una red geodÃ©sica y que los valores en sus parÃ¡metros de calidad estÃ¡n al nivel de las mejores estaciones del IGS. AdemÃ¡s, este estudio complementa la labor del IGME proporcionando informaciÃ³n sobre sus datos GPS recopilados que hasta ahora no existÃ­a.
Measurement of crustal deformation using Global Navigation Satellite System (GNSS)-based techniques was one of the methodologies used in the Topo-Iberia project. Global Positioning System (GPS) was used, and a network of twenty-six continuously operating stations (cGPS) was established on the Iberian Peninsula and in North Africa. GNSS networks require continuous control to ensure that the stations work properly and data quality is appropriate for geodynamic studies. The monitoring and quality control of the Topo-Iberia network stations, being under the charge of the University of JaÃ©n, are developed and presented for the first time in this paper. The quality control processes implemented at the CEACTierra GNSS Service are described, ranging from retrieving GPS data from stations deployed in the field to uploading the data to the Spanish Geological Survey (IGME), the institution in charge of storing them. The quality of a period of almost eleven years is studied in the case of active stations, and the most significant events analyzed. The study shows that the locations of these stations are optimal to form a geodetic network and the values in its quality parameters are on a par with the best IGS stations. Furthermore, this study complements the IGME work by providing information on its collected GPS data that previously did not exist.
Tocotrienol-Rich Fraction Of Palm Oil Attenuates Type II Collagen-Induced Temporomandibular Joint Rheumatoid Arthritis In Rats For Future Clinical Application
Authors: Ahmed S. Ahmed Ahmed
Published: September 2020

Temporomandibular joint involvement in rheumatoid arthritis (RA) is not uncommon. Nonsteroidal anti-inflammatory drugs (NSAIDs), are considered main line of RA treatment but they can cause side effects. Tocotrienol rich fraction (TRF) extracted from palm oil was reported to possess potent antioxidant and anti-inflammatory activities. This research was designed to study the therapeutic potential of TRF against TMJ arthritis. 30 Albino Wistar rats were divided into: Control (C), Arthritis (A) and Arthritis + TRF (A-TRF) groups. A-TRF group received TRF daily from day 30 up to day 45 after TMJ arthritis induction was accomplished. Serum inflammatory cytokines were assessed and TMJ histopathological examinations were done. Plasma levels of inflammatory cytokines increased in A-group and they were comparable in both C and A-TRF groups. A-TRF group showed that, the inflammatory changes were mild on examination of stained sections of TMJ. A-TRF-group bone mineral density was notably increased after TRF administration. In conclusion, the decreased plasma levels of inflammatory cytokines and the increased bone mineral density associated with tocotrienolsrich-fraction supplements administration could be provide an evidence that TRF could be used as an effective therapy of TMJ rheumatoid arthritis.

Published: September 2020

This paper seeks to report on whether there are faecal contaminants in the groundwater resources within the Tano Districts, where people use groundwater as their source of drinking water and for other domestic purposes. Total Coliforms, Faecal Coliforms, Enterococci, E.coli and Salmonella were employed as faecal indicators in this study. Determination of these faecal indicators in the samples was done using the Most Probable Number (MPN) method. A simple random sampling method was employed to get the sample size of 15 wells. The results of this study indicate that the water in the selected wells had faecal contaminants, proved by the presence of the faecal determinants in the water samples collected The presence of these organisms is an indication that water within the wells from the study area has been faecally contaminated with animal or human faeces. These bacteria are used as faecal indicators as an evidence of possible sewage contamination because, they are commonly found in animal or human faeces. Therefore, the fact that these faecal indicators have been detected in water sampled from the selected wells means that pathogens might also be present. The study recommends treatment of the groundwater supplies or encourages the use of the home water treatment.In an attempt to solve the problem of the faecal contamination of the selected wells, a future research should be conducted to determine the source of faecal contamination of ground water in wells at the Tano Districts.

La forÃªt classÃ©e dâ€™Orumbo-boka comprend de nombreuses espÃ¨ces en son sein. Lâ€™Ã©tude dans cette forÃªt classÃ©e a pour but dâ€™Ã©valuer sa diversitÃ© floristique. Pour atteindre cet objectif, un inventaire a Ã©tÃ© rÃ©alisÃ© dans cette forÃªt. Cet inventaire a consistÃ© en des relevÃ©s de surfaces et des relevÃ©s itinÃ©rants dans tous les biotopes identifiÃ©s et rencontrÃ©s dans cette forÃªt classÃ©e et dans ses environs. A lâ€™issus de cet inventaire, 281 espÃ¨ces ont Ã©tÃ© recensÃ©es. Ces espÃ¨ces sont rÃ©parties en 195 genres et 72 familles. Les familles les plus fournies en espÃ¨ces sont les Fabaceae, les Malvaceae, les Euphorbiaceae, les Moraceae et les Apocynaceae. A travers lâ€™analyse de la diversitÃ© dans les biotopes, il en ressort que les forÃªts secondaire sont plus diversifiÃ©es et abritent plus dâ€™espÃ¨ces que les autres biotopes. Parmi ces espÃ¨ces, 87 espÃ¨ces Ã  statut particulier ont Ã©tÃ© dÃ©nombrÃ©es. La prÃ©sence de ces derniÃ¨res est une raison suffisante pour la prise en compte de ces espaces fragiles.
The classified forest of Orumbo-boka includes many species within it. The purpose of the study in this classified forest is to assess its floristic diversity. To achieve this objective, an inventory was carried out in this forest. This inventory consisted of surface surveys and itinerant surveys for all biotopes identified and encountered in and around this classified forest. From this inventory, 281 species have been identified. These species are divided into 195 genera and 72 families. The most abundant families are the Fabaceae, Malvaceae, Euphorbiaceae, Moraceae and Apocynaceae. Through the analysis of diversity in biotopes, it emerges that secondary forests are more diverse and support more species than other biotopes. Of these species, 87 species of special status were counted. The presence of the latter is a sufficient reason for taking into account these fragile spaces.
