Primary refined coarse softwood thermomechanical pulp was treated with alkaline peroxide prior to low-consistency (LC) refining. The effects of the pre-treatments on pulp quality, refinability, and electrical energy consumption were assessed. Four pre-treatments were conducted with alkali charges of 2.5 and 6% and peroxide charges of 3 and 4%. The pulps were refined to specific energies up to 6...

This study was conducted to find out the effects of drinking water containing lemon juice and thyme supplemented diet on growth performance, serum concentration of cholesterol and triglycerides, heterophils (H), lymphocytes (L), H/L ratio and enzyme activity of glutathione peroxidase (GPX) in broilers under heat stress condition. The experiment was carried out as a 2 × 3 factorial arrangement w...

Introduction: Investigating the effects of colocynth pulp on levels of testosterone and changes in the reproductive system organs in streptozotocin-induced diabetic rats. Methods: In this study, 32 Wistar rats were divided into four groups of normal (N), normal+colocynth pulp (N+C), diabetic control (D), and diabetic+colocynth pulp (D+C). Groups N and D received orally 2 mL normal saline for tw...

The aim of this study was the radiographic evaluation of the apical and periapical region of dog teeth submitted to intracanal bacterial endotoxin (lipopolysaccharide, LPS), associated or not with calcium hydroxide. After removal of the pulp, 60 premolars were divided into four groups and were filled with bacterial endotoxin (group 1), bacterial endotoxin plus calcium hydroxide (group 2), salin...

The aim of this study was the histopathological evaluation of apical and periapical tissues in dog teeth that were submitted to bacterial endotoxin, associated or not with calcium hydroxide. After removal of the pulp from 60 premolars, the teeth were divided into four groups and were filled with bacterial endotoxin (group 1), bacterial endotoxin plus calcium hydroxide (group 2), saline solution...

Purpose: To formulate topical gels containing various essential oils and evaluate their antibacterial activity against methicillin-resistant Staphylococcus Aureus (MRSA) skin infections. Methods: The four essential oils namely, lemon grass, rosemary, thyme and basil were steam-distilled and then evaluated for their antibacterial activity against MRSA. Lemon grass and thyme oils were chosen for ...

background: accurate diagnosis is key to success. diagnosing the pulpal status in varied clinical situations poses a challenge to the clinician. electric pulp test (ept) is one of the valuable attempts in evaluating the sensibility of pulp tissue. the aim of this study was to find out and compare the threshold levels and optimal electrode placement site for ept in fluorosed and nonfluorosed ant...

OBJECTIVE The aim of the study was to determine blood groups and Rhesus factor from dentin and pulp using absorption-elution (AE) technique in different time periods at 0, 3, 6, 9 and 12 months, respectively. MATERIALS AND METHODS A total of 150 cases, 30 patients each at 0, 3, 6, 9 and 12 months were included in the study. The samples consisted of males and females with age ranging 13-60 yea...

background recently, the clinical use of low power lasers has increased, and it is said that wound healing is accelerated by their irradiation. the aim of this study was evaluation of the effect of platelet-rich plasma on proliferation and differentiation of human dental pulp stem cells with or without ga-al-as laser. methods: in this experimental study, human lower third molar dental pulp cell...
