Periodontium comprises of investing and supporting structures of the teeth namely Gingiva, Periodontal ligament, Cementum and Alveolar bone. Periodontal disease is a chronic inflammatory disease affecting the supporting structures of the teeth. Micro organisms present in the dental plaque are considered as the primary etiological agent for periodontal diseases. Dental plaque contains anaerobic ...

BACKGROUND Recently, tea (Camellia sinensis) flowers have attracted increasing interest because of their content of bioactive compounds such as catechins. The aim of this study was to investigate the occurrence of some characteristic compounds in tea flowers. RESULTS A principal component analysis of metabolites using ultra-performance liquid chromatography/time-of-flight mass spectrometry sh...

When a hot aqueous extract of black tea cools down, a colloidal complex (tea cream) is formed, which poses technological problems in industrial processes e.g. manufacture of instant tea and tea cordials. Removal of 'tea cream' by centrifugation leaves the residual liquor stripped to a great extent of the desirable characteristics of tea. The studies on the nature of tea cream, the mechanics of ...

Tea leaves contain abundant flavan-3-ols, which include dihydroxylated and trihydroxylated catechins. Flavonoid 3'-hydroxylase (F3'H: EC 1.14.13.21) is one of the enzymes in the establishment of the hydroxylation pattern. A gene encoding F3'H, designated as CsF3'H, was isolated from Camellia sinensis with a homology-based cloning technique and deposited in the GenBank (GenBank ID: KT180309). Bi...

Regulation of plant growth and development by light wavelength has been extensively studied. Less attention has been paid to effect of light wavelength on formation of plant metabolites. The objective of this study was to investigate whether formation of volatiles in preharvest and postharvest tea (Camellia sinensis) leaves can be regulated by light wavelength. In the present study, in contrast...

BACKGROUND AND OBJECTIVES To compare the feasibility of total laparoscopic hysterectomy (TLH) and laparoscopy-assisted vaginal hysterectomy (LAVH) in the treatment of benign gynecologic diseases and to determine the selection criteria for each technique. METHODS This was a retrospective medical records review of 168 patients who underwent TLH or LAVH performed by one surgeon. A chi-square tes...

The effect of different doses of melatonin or aqueous Tulsi (Holy Basil) leaf homogenate (TLH) was studied against piroxicam-induced gastric ulceration in rats. Melatonin or TLH was found to protect the gastric mucosa individually following piroxicam treatment. Pre-treatment of rats with increasing doses of melatonin or TLH decreased the piroxicam-induced oxidative stress in the gastric tissue....

OBJECTIVE The term 'total laparoscopic hysterectomy (TLH) with classical suture method' refers to a surgical procedure performed using only sutures and ligations with intracorporeal or extracorporeal ties, without using any laser or electronic cauterization devices during laparoscopic surgery as in total abdominal hysterectomy. However, the method is not as widely used as electric coagulation e...

BACKGROUND AND OBJECTIVES The aim of our study is to evaluate the role of electrosurgery and vaginal closure technique in the development of postoperative vaginal cuff dehiscence. METHODS From prospective surgical databases, we identified 463 patients who underwent total laparoscopic hysterectomy (TLH) for benign disease and 147 patients who underwent laparoscopic-assisted vaginal hysterectom...

We compared the duration of surgery, blood loss, and complications between patients in whom both uterine arteries were ligated at the beginning of total laparoscopic hysterectomy (TLH) and patients in whom ligation was done after cornual pedicle. Using a prospective study in a gynecologic laparoscopic center, a total of 52 women who underwent TLH from June 2013 to January 2014 were assigned int...
