A newly developed membrane performance enhancer (MPE) was used to prevent membrane fouling in a membrane bioreactor (MBR) process. It transpired that 1,000 mg/l of MPE reduced polysaccharide levels from 41 mg/I to 21 mg/I on average under the experimental condition. Repeated experiments also confirmed that 50-1,000 mg/l of MPE could reduce membrane fouling(More)
In this study, different types of indices were used to assess the ecological risk of trace metal contamination in sediments on the basis of sediment quality guidelines at Veraval Fishery Harbor. Sediment samples were collected from three sectors in pre-, post-, and monsoon seasons in 2006. Trace metal concentrations were higher in the inner sector during(More)
Cyclosporine-A (CsA) induces gingival overgrowth. Cyclosporine’s anti-apoptotic activity in human gingival fibroblast is due to desensitization of mitochondrial permeability transition pore (MPTP) and augmentation of anti-apoptotic, Bcl2. Alternative mechanisms of apoptosis exist involving enzymes like calcium-dependent Calpain and signaling events related(More)
BACKGROUND Periodontitis is a chronic, multifactorial, polymicrobial disease causing inflammation in the supporting structures of the teeth. There is a plethora of nonoral risk factors which can be quoted to aid in the development of chronic periodontitis. According to WHO, depression is a common mental disorder that presents with depressed mood, loss of(More)
Previous studies have reported the management of Class I and II papillary defects, but knowledge on Class III defects, estimated to have a poor periodontal prognosis, remains minimal. In this case report, a Class III papillary defect reconstruction was attempted mainly since the patient reported with difficulty in phonetics. In Stage I, autogenous bone(More)
