Exopolysaccharides (EPS) are the large molecular weight carbohydrate polymers extracted from higher plants, algae, fungi and bacteria. The thermophilic Bacillus zhangzhounesis 2CA and Bacillus licheniformis 2CS used in the present study were isolated from Çermik hot springs. The growth conditions of the strains designated as 2CA and 2CS in different basal media (M1, M2 and M3), different carbon sources and different concentrations of yeast extract (%w v-1: 0.05, 0.1, 0.15 and 0.2) and the amount of EPS produced were investigated. In addition, the phenol-sulfuric acid method and the Lowry method were used to determine the amount of carbohydrates and proteins within the EPS produced by the bacteria, respectively. The highest total EPS dry weight for B. licheniformis 2ÇS was obtained as 121 mg in M3 medium (0.2% yeast extract + 1% sucrose), carbohydrate content in EPS was 333.28 µg mL-1 and protein content was 0.19 µg mL-1. When these two bacteria were compared in terms of the amount of carbohydrates in the EPS produced, the highest amount of carbohydrates was found in EPS of B. zhangzhounesis 2CA (1087.03 µg mL-1). The antibacterial effects of EPS were investigated against pathogenic microorganisms (E. coli, S. aureus, K. pneumoniae and P. aeruginosa). It was determined that the highest antibacterial activity against E. coli (with 16 mm zone diameter) was obtained with EPS produced by B. licheniformis 2ÇS bacteria in M3 medium (0.2% yeast extract + 1% sucrose).

ATIVIDADE ANTI-HELMÍNTICA DE PLANTAS SOBRE NEMATOIDES DE CAPRINOS: BREVE REVISÃO
Authors: Licá Irlla Correia Lima
Published: December 2022

A infecção por nematoides gastrintestinais é considerada o principal problema sanitário da criação de pequenos ruminantes, limitando a exploração economicamente viável destes animais. A principal forma de controle sobre nematoides de caprinos é realizada com anti-helmínticos sintéticos. Entretanto, o uso inadequado de anti-helmínticos tem resultado na seleção de parasitos resistentes aos princípios ativos disponíveis no mercado. Produtos fitoterápicos com atividade anti-helmíntica surgem como uma possibilidade de tratamento simples. Além disso, reduz custos, são biodegradáveis, não causam poluição ambiental e apresentam como vantagem, o desenvolvimento mais lento da resistência. Assim, o respectivo estudo objetivou descrever a importância do uso de plantas sobre nematoides gastrointestinais de caprinos. O tipo de pesquisa realizado neste trabalho foi uma Revisão de Literatura, no qual foi realizada consulta a livros, dissertações e em artigos científicos selecionados através de busca nas seguintes bases de dados: “PubMed, Medline, Google acadêmico e Periódicos CAPES, Scholar, Biblioteca digital USP de teses e dissertações”. As palavras-chave utilizadas na busca foram: “plantas e anti-helmíntico”, “ação anti-helmíntica”, “nematoides” e dentre outros. No panorama atual, com a diminuição da eficácia dos produtos antiparasitários disponíveis, muitas são as pesquisas que buscam novos compostos ou moléculas com atividade contra os parasitos. Dessa forma este estudo demonstra que as espécies vegetais podem ser uma rica fonte de material para prospecção de atividade sobre os parasitos.

Cervical dilatation rate following augmentation of dysfunctional labour with oxytocin alone versus oxytocin and drotaverine among term nulliparas in the Rivers State University Teaching Hospital, Port Harcourt, Nigeria
Authors: Awopola Ibiebelem Jumbo  , Israel Jeremiah  , Esther Ijeoma Nonye-Enyidah  , Peter A. Awoyesuku  , Simeon C. Amadi
Published: December 2022

Background: Dysfunctional labour is the commonest abnormality of the first stage of labour. It complicates 50% of nulliparous deliveries and is associated with increased perinatal morbidity and mortality. Dysfunctional labour occurs when the progress in the active phase of labour is abnormally slow (<1 cm/hr). It is largely due to ineffective uterine contractions or slow cervical dilatation. Augmentation of labour with oxytocin is the standard management of dysfunctional labour as it enhances uterine contractions. In many cases, despite good uterine contractions slow progress persists due to cervical smooth muscle spasms. Drotaverine a smooth muscle relaxant can be used to relieve cervical smooth muscle spasms. Aim/objective: This study compared the cervical dilatation rate in term nulliparas following augmentation of dysfunctional labour with oxytocin versus oxytocin and drotaverine. Methods: The study was a single-blinded randomized clinical trial involving 156 term nulliparous women with dysfunctional labour, who were randomized into two groups. Each group had 78 participants and received either oxytocin with a placebo or oxytocin with drotaverine. They were monitored until delivery and the cervical dilatation rates in both groups were compared. Data obtained were analysed using SPSS version 23 software. The level of significance was set at 0.05. Results: The two groups were similar in their baseline characteristics, the mean pre-intervention cervical dilatation rate were also similar (0.53 cm/hr vs. 0.52 cm/hr, p = 0.85). Following augmentation, the cervical dilatation rate in the oxytocin-drotaverine group was significantly faster than in the oxytocin-placebo group (1.60 cm/hr vs. 1.20 cm/hr, p < 0.01). Conclusion: The use of drotaverine with oxytocin in managing dysfunctional labour in term nulliparous women leads to a faster cervical dilatation rate.

Authors: Manjusha Sonpipare
Published: December 2022

Acharya Sushruta says that the supreme essence of all the Dhatus beginning with Rasa and ending with Shukra is known as Ojas and that is the Bala (strenth) of the body. And strength is not depending only on physical build up but it depends on the Sara means the excellence quality of Dhatus. In the Ayurvedic text, this Dhatusarata is described with respect to Sapta Dhatu and Sattva (mind) i.e. Ashtavidhsarata which is helpful in determining the degree of strength. Examination of Dhatusarata is done at physical and psychological level. Thus biological immunity can refer to constitutive physical innate mechanisms, such as the physical protection afforded against infection by skin, the activity of natural killer (NK) cells against virus-infected cells, or the natural resistance power of the body. It is of two types innate and adoptive. Innate immunity, also known as native immunity. It is defined as the first line of defense against pathogens, representing a critical systemic response to prevent infection and maintain homeostasis, contributing to the activation of an adaptive immune response. Aim: To interpret the utility of Dhatusarata in the assessment of Innate immunity. Objectives: To take a review on Innate immunity as per Modern science to interpret the utility of Dhatusarata in the assessment of innate immunity.

Published: December 2022

Küreselleşme ile beraber pek çok farklı alanda olduğu gibi gelir eşitsizliğinde de önemli değişimler meydana gelmiştir. Bu alanda meydana gelen değişimler, bazen gelir eşitsizliğini azaltma yönünde bazen ise artırma yönünde olmuştur. Bu çalışmanın temel motivasyonu da bu farklı etkileri ortaya çıkarmaktır. Milanovic (2018) çalışmasında küreselleşmenin ülkeler arası gelir eşitsizliğini azaltırken, ülke içi gelir eşitsizliğini artırdığını ifade etmektedir. Bu çalışmada bu hipotez test edilmiştir. Analiz sürecinde öncelikle seriler arasında yatay kesit bağımlılığının varlığı sınanmıştır. Bulunan sonuçlara uygun birim kök yöntemleriyle serilerin durağanlığı test edilmiş ve serilerin düzeyde durağan oldukları bulunmuştur. Sonrasında yapılan Hausman testi ile uygun regresyon yöntemi belirlenmiştir. Çalışmada üç farklı model kurulmuştur. Birinci modelde küreselleşmenin gelişmiş ülkelerde (AB-15) kişi başına düşen geliri ne yönde etkilediği araştırılmış ve küreselleşmenin gelişmiş ülkelerde kişi başına düşen geliri azalttığı bulunmuştur. İkinci modelde küreselleşmenin gelişmekte olan ülkelerin (BRICST) kişi başına düşen geliri üzerindeki etkisi incelenmiş ve küreselleşmenin bu ülkelerde kişi başına düşen geliri artırdığı tespit edilmiştir. Bu iki model sayesinde, küreselleşmenin gelişmiş ülkeler ile gelişmekte olan ülkeler arasında gelir eşitsizliğini azalttığı ortaya çıkarılmıştır. Üçüncü modelde ise, gelişmekte olan ülkelerde ülke içi gelir dağılımının nasıl etkilendiği araştırılmış ve bu ülkelerde gelir dağılımının bozulduğu görülmüştür. Dolayısıyla, Milanovic’in (2018) iddiası regresyon sonuçları tarafından desteklenmektedir. Sonuç olarak küreselleşme; ülkeler arası gelir eşitsizliğini azaltırken, ülke içi gelir eşitsizliğini artırmaktadır.
