Silymarin is derived from the milk thistle plant, and possesses numerous pharmacological actions, including hepatoprotective, anti-inflammatory, antioxidant, and anticancer properties. The aim of the study was to the determination of influence different concentrations of Silymarin on the rumen performance in 30 local lambs (divided into three groups of 10 lambs each). In the first and second groups, 420 and 210 mg kg-1 of silymarin were administered for 8 weeks, and the third group was the control, which received normal saline solution. The parameters evaluated included the level of volatile fatty acids (VFAs), ammonia and pH in the rumen. Furthermore, the in vitro digestibility of ash, protein, fat and dry matter was investigated. These parameters were examined fortnightly, for eight weeks. The results showed that the level of volatile fatty acids and pH increased in the rumen in G1 and G2 compared to the control group, while the level of ammonia decreased in the rumen in G1 and G2 when compared to G3 (p<0.05). Silymarin increased the in vitro digestibility of crude ash (CA), crude protein (CP), crude fat (CF) and crude dry matter (CDM) in the rumen of lambs. These results indicate that silymarin can improve the digestibility of nutrient elements in the lamb rumen. Keywords: ammonia; digestibility; crude ash; crude protein; crude fat. Concentrações de silimarina nas atividades ruminais de cordeiros RESUMO: A silimarina é derivada da planta do cardo mariano e possui inúmeras ações farmacológicas, incluindo propriedades hepatoprotetoras, anti-inflamatórias, antioxidantes e anticancerígenas. O objetivo do estudo foi determinar a influência de diferentes concentrações de silimarina no desempenho ruminal de 30 cordeiros locais, divididos em três grupos (de 10 cordeiros cada). No primeiro e segundo grupo foi administrado 420 e 210 mg kg-1 de silimarina durante 8 semanas, e, o terceiro grupo foi o controle, que recebeu solução salina normal. Os parâmetros avaliados incluíram o nível de ácidos graxos voláteis (AGVs), amônia e pH no rúmen. Além disso, investigou-se a digestibilidade in vitro de cinzas, proteínas, gorduras e matéria seca. Esses parâmetros foram examinados quinzenalmente, durante oito semanas. Os resultados mostraram que o nível de ácidos graxos voláteis e pH aumentaram no rúmen em G1 e G2, em comparação com o grupo controle, enquanto, o nível de amônia diminuiu no rúmen em G1 e G2 quando comparado com G3 (p<0,05). A silimarina aumentou a digestibilidade in vitro da cinza bruta (CA), proteína bruta (PB), gordura bruta (CF) e matéria seca bruta (CDM) no rúmen dos cordeiros. Esses resultados indicam que silimarina pode melhorar a digestibilidade dos elementos nutrientes no rúmen do cordeiro. Palavras-chave: amônia; digestibilidade; cinza bruta; proteína bruta; gordura bruta.
Background: White spot lesion is the first visible sign of dental caries that is characterized by demineralized lesion underneath an intact surface. Several studies demonstrated that they could be treated using noninvasive techniques like the use of fluoride or casein phospho-peptide and amorphous calcium phosphate. Improvement in aesthetic outcomes by covering the demineralized enamel is one of the advantages of the use of resin infiltration and opal-ustre microabrasion, which are two new techniques that had been used for treatment of white spot lesion. The purpose of this study was to evaluate the impact of resin infiltration and microabrasion in the microhardness of the artificial white spot lesions at various depths. Material and method

This is the twentieth gyrodactylid species to be recorded from fishes of Iraq. The description and measurements of this parasite as well as its illustration were given.
Literature on the use of the first-person pronoun in abstracts and conclusion sections of final-year projects is limited. In case of Algerian Master students, it is too scant. The present paper aims at filling this gap through a study concerned with students’ and engagement in their final projects (memoirs). This quantitative study examines the use of “we” and its various types, “our- us-I, my, the researcher” in memoirs chosen at random from the d-space portal of the University of Adrar, southern Algeria. Sixty-five papers, submitted in the fields of Linguistics or didactics between 2015 and 2020 and representing nearly half of the whole memoirs’ depository at the library’s d-space, constituted the corpus of study.

Players are usually faced with difficulties at the beginning of learning due to lack of coordination in ball striking thus including a teaching aid will have a positive effect on learning some forehand and backhand skills. The research aimed at designing exercises using teaching aid in tennis as well as identifying the effect of these exercises on the accuracy of performing forehand and backhand shots in tennis. The researcher used the experimental method on (38) tennis players from Al Zewra

Show MoreBirds of prey (Raptors) are top predator avian species that many migrate annually through Mesopotamian marshes in southern Iraq toward their wintering grounds in Arabia and Africa, while others are breeding residents; however, information on their current status is scarce. From January 2016 to April 2019, a total of 20 field expeditions were conducted in the geographical zone of the Mesopotamian marshes, wetlands of international importance. The survey covered the Central Marshes, Al-Hammar and Hawizeh Marsh. One of the objectives of the field surveys is to list the raptors species that wintering and/or migrating through the Mesopotamian marshes and to understand their current spatial and temporal distribution.

The problem with CLs is loading of hydrophobic drugs. In this research the CLs were prepared with molecular imprinting MI to enhance the loading of itraconazole, which is used as antifungal drug for fungal keratitis. CLs using different concentration of hydroxyethyl methacrylate HEMA and methacrylic acid MAA were prepared with and without MI using PEGDA (25 μL) and AIBN (37 mg) as crosslinker and initiator respectively. All the prepared CLs were clear and have good folding endurance. MICLs had significantly higher drug loading compared to conventional CLs. The release of i
