This experiment aimed to reveal the effect of serum G-antigen of M. domesticainsect larvae (LAS) as promoter antigen on serum immunoglobulin production in organically managed goat livestock. This study used 12 local goats which were divided into two groups: as a control group and treated group receiving treatment. Insect rearing was conducted to obtain the larvae, the antigen-G was then extracted from the larvae to be used as promoter antigen to enhance the serum antibody production which was subcutaneously immunized in experimental goats and incubated for a period of 14 days. Blood collection of 2.5 ml was taken through the jugular vein and then carried out a quantification of serum protein level indicating the antibody proportion of goats. The data of the LSA extract proportion level were statistically analyzed with t-test, and the quality classification level of serum immunoglobulin of animal groups were statistically analysed. The results showed that the serum of animal treated with LSA of M. domesticaresulted in a higher level of immunoglobulin (P <0.01) compared to the control. We conclude that the antigen-g substance (LSA) could support the efforts to improve the production of organic goat livestock by increasing the total level of antibodies circulating in the blood.

Published: September 2020

Abstract
We aim to describe the diagnosis and surgical management of urinary tract endometriosis (UTE). We detail current diagnostic tools including advanced transvaginal ultrasound, magnetic resonance imaging, and surgical diagnostic tools such as cystourethroscopy. While discussing surgical treatment options, we emphasize the importance of an interdisciplinary team, for complex cases that involve the urinary tract. While bladder DE is more straightforward in its surgical treatment, ureteral DE requires a high level of surgical skill. Specialists should be aware of the important entity of UTE due to the serious health implications for women. When UTE exists, it is important to work within a interdisciplinary radiological and surgical team.

Published: September 2020

This study aimed at investigating the effect of employing intensive reading (IR) authentic tasks as supplementary materials on reading comprehension development of Academic IELTS test takers within the framework of schema theory and three instructional models of reading strategies suggested by Pearson and Duke (2009). Participants of this study consist of 81 individuals comprising 41 male and 40 female language learners at pre-advanced level of English proficiency with the age range of 25 to 37 among which 42 were categorized as the experimental group which received IR treatment and the rest of 39 ,who are considered as control group, that did not receive IR treatment. The experimental group was further divided into two subgroups which each received the same IR authentic tasks with different instructional methods to teaching reading strategies. The results of an ANCOVA analysis illustrated a significant positive influence of authentic IR treatments on the development of participants' reading comprehension skills. However, an independent one-way t-test revealed that Pearson's and Duke's (2009) various instructional methods were not significantly influential on participants' final reading proficiency development.
