The study examined the sustainability of consumer textile technology entrepreneurship amidst its structural normative in southwest rural area of Nigeria. It explicitly analyzed entrepreneurial cultural traits and economics agility needs related variables of the entrepreneurship influences on sustainability. The study was conducted in the rural southwestern region of Nigeria. Four states (Lagos, Ondo, Oyo, and Ogun) were randomly selected from the region. Multi-stage and stratified sampling techniques were used in selecting 1,649 consumer textile entrepreneurs across the states. Questionnaire, key informants and focus group discussion (FGD) guides were employed in data collection. While descriptive statistics were used in describing the data, correlation analysis was applied in establishing direction of influence between sustainability and structural normative of consumer textile technologies entrepreneurship Sustainability level of the entrepreneurship in southwest rural area of Nigeria was average. Respondents were independent entrepreneurs of favorable attitude towards the enterprise. While 52.7 percent were averagely proactive, 58.8 percent were averagely risk-averse with exhibition of low creativities skill on the entrepreneurship. The entrepreneurs possessed average knowledge of competitive advantage and networking strategies needs on the job but skills practices was poor. While 33.0 percent exhibits fairly good managerial skill on the job, 20.8 percent displayed high, and 46.2 percent was low. CTT entrepreneurial traits needs related variables {proactive aptitude (r = 0.620), autonomy value (r = 0.591), fatalism (r = -0.317), marketing system (r=0.574), disposition (r= 0.409), risk averse (r= -0.344), and economic agility needs {(competitive strategic skill (r = 0.318), networking (r = 0.501), labor accessibility (r = 0.321)} showed significant relationship with sustainability. It was established that respondent’s proficient in CTTE entrepreneurial traits related variables and economic agility were paramount in the sustainability, nevertheless there is need to establish related schools or vocational training centers for skill acquisitions and updating on the entrepreneurship in the studied area. Change agents and other related organizations that were involve in technology transfer and rural development should create awareness program on potential values and benefits of the entrepreneurship mostly in turning wastes to wealth. This would enhance enlightenment for building better positive attitudes toward CTTE. The environment must be made livable through job creation and accessible infrastructure to prevent migration and attracts youth’s influxes into the community. This would also enhance labour availability and patronage. Standard cluster market should be established in the vicinity to enhance expertise and inputs supply.

Authors: Hasan Md Mahamudul , Islam Rafiqul
Published: March 2024

Bamboo fiber has become a viable and environmentally beneficial option in the textile industry because of its sustainable qualities and appealing characteristics. Nevertheless, the inherent difficulties associated with untreated bamboo fiber, such as limited absorption of dyes and inadequate mechanical durability, need the use of efficient pretreatment methods to improve its suitability for textile purposes. This article critically analyses current improvements in chemical pretreatment procedures that seek to enhance the quality of bamboo fibers for textile applications. The usefulness of different pretreatment procedures, including alkali treatment, enzymatic treatment, bleaching, and mercerization, in changing fiber qualities is thoroughly assessed. This article examines the influence of pretreatment on many properties of bamboo fibers, such as their shape, mechanical strength, dye absorption, and process ability. In addition, the study outlines important areas of research that have not yet been explored and suggests future paths for the subject. It emphasizes the potential for innovation and cooperation to further enhance bamboo fiber pretreatment technology. In summary, this analysis enhances our comprehension of how chemical pretreatment improves the quality of bamboo fibers and encourages sustainable practices in the textile sector.

Nonsteroidal anti-inflammatory drugs, which are widely used in the treatment of diseases accompanied by pain and fever, can cause diseases of the gastrointestinal tract and are associated with disturbances of the intestinal microbiota. The search for new compounds that could affect the community of microorganisms, exhibiting antimicrobial and anti-inflammatory effects, is an important task of modern medicine and veterinary medicine. One of the promising molecules that have such effects are 4-thiazolidinone derivatives. The aim of this study was to analyze the effect of the newly synthesized compound Les6490 and drug nimesulide on the intestinal wall microbiota of rats in vivo under the conditions of Freund’s adjuvant-induced inflammatory process. The study of the effect of the above-mentioned drugs on the intestinal microbiota in vivo was carried out on a biomodel of rats, which were intragastrically administered with the test substances for two weeks. The study material was the parietal mucos of the small intestine, the microbiome of which was studied using 16S rRNA sequencing. Metagenomic analysis made it possible to analyze the types of microorganisms in experimental groups with induced inflammation (groups A and AL) and without it (groups K, L, N). It was established that the composition of the microbiome of the intestinal tract of rats changes under the conditions of induced inflammation and under the action of the compound Les6490 (groups A and L) in comparison with the control group (group K). The influence of Les6490 on the intestinal tract microbiome composition in rats is similar to that of nimesulide, but the effect is more pronounced. The compound Les6490 potentiates the growth of Helicobacter and has an effect against Stenotrophomonas in the group without induced inflammation (group L), but in the group of inflammation (group AL) no such effect is observed. The compound alone (not in inflammation models) leads to increased species diversity of the rat gut microbiome.
The influence of heat stress on the antioxidant protection glutathione link and the content of lipid peroxidation products in chicken liver
Authors:   Institute of Animal Biology NAAS, 38 V. Stusa str., Lviv 79034, Ukraine, Perederiy D. B.
Published: March 2024

Heat stress is one of the main reactions of the body’s response to environmental factors, negatively affecting the welfare of various animal species. An increase in environmental temperature can cause stress, which, in turn, potentially has various negative consequences for animals including disruption of the antioxidant system functioning. Violating the antioxidant-prooxidant balance can lead to an increased free radicals formation in the body, which can damage cells and promote the development of various diseases. The article presents the study results of the artificially simulated heat stress effect on individual indicators of the antioxidant system and lipid peroxidation products in the chickens’ liver. The choice of these animals for this study is due to the fact that the poultry is particularly sensitive to the elevated environmental temperatures and, accordingly, to heat stress. This is caused by the biological peculiarities of birds, in particular, they lack sweat glands, and their body surface is mostly covered with feathers, which, together with the high density of keeping in the industrial poultry farming, often leads to the heat stress. The purpose of this work was to find out the presence or absence of changes in individual indicators of the antioxidant system glutathione link and the lipid peroxidation products content in chickens’ liver. The analysis of indicators such as lipid hydroperoxides (LOOH), TBA-active products, reduced glutathione (GSH), glutathione peroxidase (GSH-Px) and glutathione reductase (GR) will allow us to obtain information about the body’s antioxidant defense system state and the oxidative stress level under heat stress conditions. In this study we used 18 hens of the white Leghorn breed. The research was conducted in the vivarium of the Institute of Animal Biology of the National Academy of Sciences in two stages. During the first stage, chickens were kept at an air temperature of 20°С for 7 days. During the second stage, we created heat stress conditions by increasing the temperature to 35°С 6 hours a day, also for 7 days. It has been found that as the ambient temperature increased, the content of LOOH, GSH, and activity of GSH-Px in the liver of chickens increased (P<0.01), while, on the contrary, the content of TBA-active products and activity of GR decreased (P<0.01). The obtained data prove the heat stress effect on the antioxidant protection glutathione link in chicken liver. Research results can be of practical value for improving the bird keeping conditions in the industrial poultry farming, developing strategies for protection against stress, and improving the conditions to ensure the animals’ welfare and health.

ЕГОЦЕНТРИЗМ ЯК ОДИН З ЧИННИКІВ НЕЗАДОВОЛЕНОСТІ ОСОБИ МІЖОСОБИСТІСНИМИ СТОСУНКАМИ
Authors: Бунас А.А. , Диба Ю.С.
Published: March 2024

Сучасний темп та спосіб життя людей породжує ідею індивідуалізму, центрації на собі, власних думках, вчинках, що закономірно відображається на якості міжособистісних стосунків. У статті досліджено феномен егоцентризму та його місце в зумовленні незадоволеності міжособистісними стосунками. Егоцентризм визначено як соціально-психологічне явище та специфічну форму переживання особистості, що характеризується нездатністю суб’єкта, зосередженого на своїх інтересах, брати до уваги думки, інтереси, плани, точку зору іншого, а також координувати все зазначене з власними намірами, метою, бажаннями тощо. Зазначено, що міжособистісні стосунки варто розглядати як суб’єктивно пережиті, різною мірою усвідомлювані взаємозв’язки між людьми з домінуванням особистісного компонента, які при цьому мають взаємну спрямованість та значущість. На відміну від інших типів взаємин, міжособистісні стосунки мають специфіку, глибину, обмеження, відповідальність за себе й іншу людину, з якою контактують. Зосереджено увагу на соціальній природі людини, її базових потребах у прийнятті, любові, близькості. В результаті емпіричного дослідження виявлено значущі додатні кореляційні зв’язки між рівнем егоцентризму та актуальністю матеріальних потреб, незалежністю, прийняттям боротьби, включеністю (від інших до індивіда) та афектом (від інших до індивіда), що свідчить про існування зв’язку егоцентризму як із внутрішніми, так і з зовнішніми компонентами міжособистісних стосунків. При цьому не існує значущих відмінностей в особливостях прояву показників задоволеності та незадоволеності міжособистісними стосунками залежно від рівня егоцентризму, що може свідчити про універсальність обраних компонентів задоволеності, які властиві людям загалом. Визначено формувальні складові задоволеності (високий рівень довіри до себе, актуальність соціальної потреби, потреби у визнанні, товариськості, прийняття боротьби) та незадоволеності (егоцентризм, актуальність потреби в безпеці, нетовариськість, прийняття боротьби) міжособистісними стосунками. Встановлено зумовлену егоцентризмом незадоволеність міжособистісними стосунками.
Therapeutic evaluation of activatable melittin for selective treatment of leishmaniasis in vitro and in vivo
Authors: Akhzari S. , Nabian S. , Taheri M. , Salimabadi Y.
Published: March 2024

Leishmaniasis is a major public health problem worldwide. Because of its high prevalence, the development of an effective treatment is especially important. Drug delivery systems are promising pharmaceutical formulations for improving the therapeutic index of drugs. In this study, activatable melittin (AM) peptide was designed and encapsulated with albumin and liposome for selective targeting of Leishmania infected cells. The effect of AM was determined by measuring its cytotoxicity and pathologic effects using Giemsa and haematoxylin/eosin staining, respectively. The results of this study showed that the toxicity of designed AM is reduced compared to wild-type melittin, in addition to the use of AM-loaded albumin nanoparticle and liposome containing AM and their therapeutic role against cutaneous leishmaniasis caused by L. major. The encapsulation of AM with albumin and liposome as a non-toxic carrier at a concentration of 25 µg/mL can improve and optimise the antileishmanial effects of this drug, so, infected cells treated with AM in albumin nanoparticle and liposome had less Leishmania major promastigotes. These forms of the drug could be a good alternative to the current drugs so performance of further in vivo studies is suggested.
Gender and jazz research in Spain
Authors: Munoz-Garcia Rebeca , Tobio-Soler Constanza
Published: March 2024

During the last two decades, the little jazz research that has been conducted in Spain has focused on examining both flamenco jazz, as the most important contribution of Spanish culture to jazz, and sociocultural meanings of jazz development, mainly from a political and historical perspective. This period has also coincided with a significant development in jazz studies outside of the United States, and a key juncture for gender and feminist studies in Spain that concurred with the emergence of fourth-wave feminism. Spanish gender research in music has traditionally focused on written music, paying scant attention to jazz, although popular music is slowly becoming a significant focus of research. Far from seeing this as a drawback, we propose that the underdevelopment of knowledge production is an opportunity for a feminist-inspired overview, and a re-reading of jazz cultures and jazz research in Spain as we ‘listen’ for the relationships between gender and jazz as interdisciplinary fields of research. The article concludes that Spain presents fertile ground for a comprehensive exploration of its own jazz culture as research here strives to find its own voice.

The changing face of my jazz photographic practice
Authors: Homer Brian
Published: March 2024

This article is a reflection on my jazz photography practice and how it has changed with my involvement in academic research after becoming actively involved in the Jazz Studies cluster at the Birmingham Centre for Media and Cultural Research (BCMCR), Birmingham City University and starting a close collaboration with jazz scholar Dr Pedro Cravinho. My practice evolved from photographing musicians playing at gigs to visualising the jazz scene and musicians from a different perspective which includes aspects of their off-stage lives. Through our discussions and common interests in the local jazz scene(s), Cravinho and I began developing a research process in which photography is the visual driver but is underpinned by Pedro’s rigorous academic input. Our collaboration is built on my documentary photography practice and Pedro’s ethnomusicological research background.
Green in blue

The global commodification of jazz (and indeed culture more generally) has contributed to significant and enduring environmental consequences. The various physical formats through which it has been disseminated have each employed by-products of the petrochemical industry in their production and distribution, and the environmental cost of digital streaming platforms has more recently been observed as contributing further to the carbon footprints of music producers and consumers. International and regional travel by touring artists and festival audiences has similarly been recognized as having negative environmental impacts through associated air, sea, and land transport emissions and through increased burden on host-location infrastructures. The environmental implications of culture have come increasingly under scrutiny as society becomes conscious of individual and collective contributions to, and imperative mitigations against, critical anthropogenic climate change. This article seeks to explore the machineries of jazz dissemination, foregrounding the festival as a place of coming together in celebration of music and community, and considers how the road ahead may look as we attempt to green our engagement with culture while safeguarding its intrinsic values and modes of experience. It questions, therefore, whether the art form that spearheaded the ways in which we currently interact with live and recorded music can similarly lead us in addressing urgent and necessary paradigm shifts in the means and methods of cultural production and consumption.

Authors: JĘDRYCZKOWSKI JACEK
Published: March 2024

Artificial intelligence mechanisms enable fast speech transcription and printed text recognition (Optical Character Recognition). Speech synthesizers for reading any digital documents have also become popular. In most cases, these are free solutions that can significantly support the education and functioning of people with visual and hearing impairments. Unfortunately, the knowledge of parents and caregivers on this subject is insufficient. Bearing this in mind, a suitable series of educational videos was prepared and published on YouTube. Subsequently, research was conducted to determine whether and to what extent there is a demand for video materials on this topic. For this purpose, the method of implicit observation was used, carried out using YouTube Analytics mechanisms. Its results are available in the form of numerous reports and summaries. Based on the collected materials, a considerable interest in the study was found. It was possible to determine which issues are of particular interest to the recipients. The obtained results will allow for further development of the educational offer.

Possibilities of Digitalization of the Qualification Thesis Topic Submission Process
Authors: KLEMENT MILAN
Published: March 2024

The challenges associated with the process of awarding and processing qualification work can be traced both in the area of efforts to improve the quality of this specific process and in the area of supporting the digitisation of the study agenda in general. Given that the core processes at the university rely on highly skilled professionals, digitising processes is not as straightforward as it would be for more mechanical work. Although universities have a long tradition of organising work, they have not yet paid much attention to digitised processes.

For this reason, we developed and piloted a flexible electronic workflow for digitizing a selected process and tested it under real-life conditions, including the implementation of qualitative research. The results show the usefulness and adaptability of the proposed electronic workflow from the perspective of its users.

Authors: Pietryga-Szkarłat Barbara
Published: March 2024

The most important factor determining human health is his lifestyle. One of the elements of a healthy lifestyle is physical activity, which allows you to maintain not only good physical but also mental shape, guaranteeing a high level of quality of life. The stage of early adulthood is a special period in which a young person takes full responsibility for their own health and life. Based on his own experience and knowledge, he shapes his individual lifestyle. The academic environment can affect young people studying both positively and negatively, leading to the initiation or consolidation of certain behaviors that are unfavorable from the point of view of health. Taking into account the above position, the aim of the research was to characterize health behaviors presented in the environment of academic youth in the field of physical activity. 245 students of humanities and sciences took part in the study. An original questionnaire was used in the study. The undertaken research shows that young people studying present an insufficient level of physical activity and prefer passive forms of spending free time. The obtained research results can be a scientific basis for constructing health promotion programs in the academic environment aimed at expanding students’ awareness of the impact of physical activity on health and the consequences of a passive lifestyle.

Introduction: University students are exposed to academic demands that could impact mental health and trigger suicidal behaviors. Objective: To analyze the mental health conditions (depression, anxiety, and social support) and suicide risk in Costa Rican university students. Materials and Methods: Correlational, predictive, and cross-sectional research was conducted. A census sample of 76 university students was included. Variables encompassed sociodemographic data, social support measured by the Multidimensional Scale of Perceived Social Support, depression measured by the Beck Depression Inventory-II, anxiety measured by the Beck Anxiety Inventory, and suicide risk measured by the Plutchik Suicide Risk Scale. An online survey was used. Descriptive analysis, variance analysis, Pearson correlation, and multiple linear regression were performed. Significance level set at p<0.05. Results: The student body had a mean age of 19.43 years ±1.75, with gender identity evenly distributed. 38.20% reported moderate-severe symptoms of depression, and 32.90% indicated suicide risk. Differences were observed between gender identity in terms of social support and anxiety (p<0.05). Correlations were found between mental health conditions and suicide risk (p=0.001). Depression was identified as a factor contributing to an increased risk of suicide (p=0.001). Discussion: Previous literature confirms that mental health conditions such as low social support, depression, and anxiety in university students would predispose to the suicide risk. Conclusions: There is a segment of the university student population experiencing adverse mental health conditions and suicide risk, for whom care strategies focused on their needs should be developed.
Profitability Analysis of Markets Traded on Borsa Istanbul
Authors: Dayı Faruk , Adaiem Nasreddin
Published: March 2024

Supermarkets significantly increased product prices in response to the sudden and sharp rise in the exchange rate in July 2018. A similar situation unfolded in 2021 when interest rates dropped, and the exchange rate experienced a steep increase. The surge in demand for foreign currency and subsequent interest rate cuts led to an escalation in the exchange rate. Consequently, production costs rose due to inflated raw material prices, resulting in higher product prices. Additionally, supermarkets allegedly engaged in cartel-like behavior, purposely withholding products from sale, further contributing to price hikes between 2021 and 2022. This study evaluates whether supermarkets garnered substantial profits during the period. Financial statement data from 2018 to 2022 was analyzed using vertical, trend, and ratio analyses to assess the financial position and profitability of five companies listed on Borsa Istanbul. Throughout the 2018-2022 period, except for 2022, BIM demonstrated the highest return on assets ratio. The return on assets ratios for 2022 and 2021 exhibited an upward trend, indicating an increase in profitability during 2022. SOK recorded the highest return on equity ratio in the 2018-2022 period, while CarrefourSA reported the lowest. Furthermore, the companies witnessed notable growth in revenues, gross sales profitability, and net profitability in 2022, surpassing previous years. This suggests they earned more profit by increasing prices at a greater rate than their costs in 2022. The operating profitability of the companies also experienced an upswing during this period. BIM held the largest share of operating profit in revenues in 2022, while CarrefourSA possessed the smallest share. In terms of net profitability, the companies fared better in 2022 compared to 2021, with net profitability exhibiting a more substantial increase during 2022.
Regional cooperation and Poland’s military security
Authors: Drab Lech
Published: March 2024

Each state, through participation in international relations, constantly strives to ensure and then maintain an appropriate level of security. Functioning in the environment of other countries, it must pursue many interests, thanks to which it guarantees its survival, but at the same time ensures comprehensive development. The security of citizens of each state depends on many factors, including geopolitical and military conditions. One of the most important factors guaranteeing both the stability of the state’s constitutional order and the protection of its democratic values is political security. Ensuring it requires maintaining state structures in constant readiness in order to take up challenges, reduce threats and take advantage of opportunities in the political aspect. Closely related to this factor is military security, which concerns the relations between the state and the international environment, in which the military factor plays an important role. This requires maintaining the state’s own military capacity as optimal as possible and participating in adequate military alliances to prevent threats. The security of Poland and the region is usually perceived in the context of our participation in the most important international organizations, such as: the United Nations (UN), the North Atlantic Treaty Organization (NATO), the European Union (EU), the Organization for Security and Cooperation in Europe (OSCE). However regional initiatives are equally important. The aim of the article is to analyze selected regional initiatives and their impact on ensuring Poland’s military security.
The impact of new technologies on the safety of older people
Authors: Pączkowski Tomasz
Published: March 2024

Since the 1980s, Poland has seen a steady increase in the share of people aged 60+ in society. This phenomenon is connected with a fundamental technological revolution, especially in social communication. In the past, the ability to read and write was enough to communicate remotely, but today, with the development of information technology, knowledge of how to use many devices and communicators is necessary to avoid social exclusion. This creates many problems for older people in mastering technologies they had no contact with in their youth. But this revolution also brings about positive phenomena, which we will mention later…

Psikolojik dayanıklılığın çok güçlü olması gereken iş kollarından birisi de çağrı merkezleridir. Yoğun iş yükü ve stres altında çalışan çağrı merkezi çalışanlarının, zorluklarla mücadele edebilme güçleri psikolojik dayanıklılık seviyesine bağlı olarak değişkenlik göstermektedir. Literatürde sektörle ilgili araştırmaların sınırlı olması nedeniyle, çalışma kapsamında, çağrı merkezi çalışanlarının psikolojik dayanıklılık algılarını, bu dayanıklılığı olumlu ve olumsuz etkileyen faktörleri, psikolojik dayanıklılığı güçlendirmek adına tercih edilen strateji ve yöntemleri keşfetmeye odaklanan bir araştırma gerçekleştirilmiştir. Bu amaçla araştırmada, farklı çağrı merkezlerinden seçilen dokuz (9) çalışan ile nitel araştırma yöntemlerinden odak grup görüşmesi yapılmıştır. Verilerin analizi sonucunda, çalışanların psikolojik dayanıklılığı; zorluklarla başa çıkma, olumlu tutum, stres altında performans, empati, müşteri iletişimi ve motivasyon koruma olarak tanımladıkları görülmüştür. Ayrıca, iş ortamında destekleyici ekip ve yöneticinin varlığı, düzenli geri bildirim, eğitim ve gelişim fırsatları, açık iletişim ve takdir edici iletişimin psikolojik dayanıklılığı güçlendirici faktörler olduğu belirlenmiştir. Bununla birlikte, olumsuz müşteri etkileşimleri, yüksek tempolu iş ortamı, teknolojik sorunlar, sürekli değişen iş koşulları ve uzun çalışma saatleri gibi durumların çalışanların psikolojik dayanıklılığını zorladığı tespit edilmiştir. Çağrı merkezi çalışanları zorluklarla başa çıkmak için dinlenme, duygusal kontrol, etkili iletişim, kişisel bakım, hizmet içi eğitim ve zaman yönetimi stratejilerini kullanmaktadırlar. Araştırma sonucunda, psikolojik dayanıklılığı artırmak için stres yönetimi, takım aktiviteleri, sürekli öğrenme, kişisel beceri eğitimleri, psikolojik danışmanlık hizmetleri ve esnek çalışma saatleri gibi stratejilere odaklanmanın faydalı olabileceği sonucuna varılmıştır. Aynı zamanda, psikolojik dayanıklılığın istikrarlı ve sürdürülebilir bir şekilde nasıl güçlendirilebileceği konusunda öneriler sunulmuştur.
Des amphis à l’expérience de la rue

Au Tchad, l'une des conséquences du COVID-19~a été la fermeture des écoles sur l'ensemble du territoire national, le 19~mars 2020, date de l'apparition du premier cas positif en provenance du Cameroun. L'éducation a été l'un des secteurs le plus durement affecté par la pandémie avec l'arrêt brutal des activités. Dès lors, le gouvernement et les autres partenaires ont conjugué leurs efforts pour sauver l'année en développant l'enseignement à distance et ce, en dépit de nombreux disfonctionnements. Mais en dehors des actions institutionnelles, il y a lieu de noter que des initiatives ont foisonné chez les acteurs concernés, notamment les enseignants et les apprenants. L'implication des élèves et étudiants dans des activités diverses pour faire face à la crise peut être appréhendée dans deux axes~: social et symbolique. D'une part, elle traduit une volonté personnelle de contribuer au développement des apprentissages; d'autre part, elle est dictée par l'impératif de survie dans un contexte économique paralysé. Ce chapitre interroge la capacité de résilience et d'ingéniosité des apprenants face à cette crise aux conséquences multidimensionnelles, hors des salles de classes et des amphis. Pour appréhender les contours de cette réalité, en plus des articles de revues, des entretiens de terrain sont réalisés avec des étudiants autour de leurs initiatives novatrices.
La décentralisation au Sénégal
Authors: KANE Ibrahima
Published: March 2024

Contrairement à son esprit, la décentralisation, par un dévoiement depuis l’indépendance, est très hypothétique à supporter le développement local au Sénégal. L’objectif est alors, par le cas sénégalais, de procéder à une analyse critique de la décentralisation. La revue documentaire, axe majeur des investigations, les observations du jeu des acteurs et les entretiens individuels libres avec des personnes ressources, notamment des élus locaux, ont alors livré une mine de données théoriques et empiriques sur la décentralisation, notamment au Sénégal. L’analyse comparative de celles-ci a permis d’aboutir aux résultats suivants.
La décentralisation, par un partage des pouvoirs et compétences et une gouvernance de proximité plus démocratique, efficiente et efficace, doit favoriser le développement local. Malheureusement, elle relève plus d’une adaptation conjoncturelle que d’une volonté politique, révèle plus une lutte pour le pouvoir qu’une collaboration pour des intérêts nationaux et des moyens trop faibles pour l’exercice optimal du pouvoir et le développement local. La conscience et l’acceptation d’un État unitaire, la promotion de la participation citoyenne et l’application diligente de la deuxième phase de l’acte 3 de la décentralisation sont alors des pistes sérieuses pour le retour gagnant à l’esprit de la décentralisation.

Although cardiac involvement is rarely seen in Behcet’s disease (BD), it is essential to detect subclinical left ventricular (LV) dysfunction for prognostic purposes. Herein we aimed to show the role of two dimensional (2D) speckle tracking echocardiography (STE) in determination of  subclinical LV dysfunction in patients with BD. 30 patients diagnosed as BD due to International Study Group Behcet’s diagnostic criteria and 25 control subjects underwent Doppler echocardiography including pulsed tissue Doppler of the mitral annulus and speckle-tracking echocardiography. LV peak longitudinal strain and strain rate (SR) was calculated in four-chamber (4C), apical long-axis (LAX), and two-chamber (2C) views, and values of the three views were averaged LV global longitudinal strain (LV-GLS) and SR. LV torsion was determined as the net difference in the mean rotation between the apical and basal levels. There was not any significant difference in age and gender between groups. Patients with BD had significantly lower LV longitudinal strain and Sr measurements than the control group. Although LV basal rotation (LVR) basal values were similar in both groups, LVR-apical and LV torsion (LVTR) values were significantly higher in patient group. LVR-apical and LV-GLS were found to have a good positive corelation (r:0.44, p<0.001) (r: -0.56, r: -0.65,respectively. p<0.001). There was a weak positive correlation between LVTR and LV-GLS (r: 0.29, p<0.05). We demonstrated that combined assessement of LV-GLS, LV-GLSR, LVTR and LVR-apical values detected by STE can be useful in determination of subclinical left ventricular dysfunction in BD.

Two new nickel(II) and cobalt(II) complexes, [Ni(MPAFA)3](BF4)2 (I) and [Co(MPAFA)3](BF4)2 (II) were synthesized from a pyrazole containing ‘NN’ bidentate Schiff-base ligand, N-(furan-2-ylmethyl)-1-(5-methyl-1H-pyrazol-3-yl)methanimine, (MPAFA) (L). The complexes I and II were characterized by various physico-chemical and spectral parameters. Both I and II were 1:3 (M:L) coordination complexes and behaving as 1:2 electrolytes. Single crystal X-ray diffraction studies revealed that both of them were distorted octahedral in nature with a N6 donor set. The binding interactions of the complexes with CT-DNA were studied by UV-Vis and fluorescence spectroscopic methods. I was found to bind with CT-DNA in a partial intercalative mode, whereas II bound via the groove-like manner in solutions. The ligand and the complexes were shown to have potential photocatalytic activity in degrading methylene-blue (MB) under UV-Vis light irradiation.

Poor aqueous solubility often results in poor dissolution behavior and, consequently, poor bioavailability for those drugs whose intestinal absorption is dissolution rate limited. It is essential for formulation scientists to identify strategies to improve the solubility and dissolution rate of candidate drugs in order to improve their bioavailability. The present study investigated electrospun polymeric nanofibers for efavirenz (an antiretroviral drug), a Class II drug in the Biopharmaceutical Classification System. In order to fabricate nanofibers, hydrophilic spinnable polymer like Soluplus was used. Statistical design of experiments was used to optimize electrospinning parameters. Scanning electron microscopy (SEM) studies confirmed the presence of nanofibrous material in the mat. The x-ray diffraction (XRD) and differential scanning calorimetry (DSC) studies advocated the amorphization of efavirenz in the nanofiber samples. The optimized nanofiber-based platform significantly improved in vitro dissolution of efavirenz (89.0 ± 3.2% in 120 minutes) compared to pure efavirenz crystals (27.3 ± 2.4%).
