This novel image restoration method, which we termed sparsity based simultaneous denoising and interpolation (SBSDI), utilizes sparse representation dictionaries constructed from previously collected
BVD-523 supplier datasets. We tested the SBSDI algorithm on retinal spectral domain optical coherence tomography images captured in the clinic. Experiments showed that the SBSDI algorithm qualitatively and quantitatively outperforms other state-of-the-art methods.”
“OBJECTIVE: To determine the conjunctival bacterial flora present in patients with Stevens-Johnson syndrome.
METHODS: A prospective study of the conjunctival bacterial flora was performed in 41 eyes of 22 patients with Stevens-Johnson syndrome. The information gathered included buy MK-8931 the patient’s sex and age, the duration of disease, the cause of Stevens-Johnson syndrome, and treatments. Scrapings of the inferior conjunctival fornix were performed in both eyes. Fourteen days before scraping, the patients were asked to interrupt all topical medication and start using 0.5% nonpreserved
methylcellulose. The microbiological evaluation included microorganism identification and determination of antibiotic sensitivity.
RESULTS: Of 22 patients (41 eyes), 14 (64%) were females, and eight (36%) were males. The mean age was 33.2 years, and the mean duration of disease was 15.6 years. Visual acuity ranged from light perception to 20/25 (1.57 logMar). The treatment received by most patients consisted of tear substitutes, topical antibiotics, and contact lenses. Bacterial identification was positive in 39 eyes (95%) and negative in two eyes (5%). Gram-positive cocci accounted for 55.5% of the microorganisms, whereas gram-positive bacilli and gram-negative bacilli accounted for 19% and 25.5%, respectively.
Half of the patients (54%) had multiple bacterial species in their flora, and only one bacterial species was identified in the other half. Resistant bacteria were isolated from four eyes. The antibiotic sensitivity results for the Streptococcus HIF inhibitor group showed the lowest sensitivity and the highest microbial resistance identified.
Patients with Stevens-Johnson syndrome have a diverse conjunctival flora that includes many pathogenic species.”
“The present study was designed to investigate antioxidant, antidiarrhoeal and cytotoxic potential of hydromethanolic extract of the fruit rind of Punica granatum Linn. A dose dependent scavenging of DPPH radical and NO was observed with significant total antioxidant capacity with the plant extract in 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging, total. antioxidant capacity and nitric oxide (NO) scavenging assays. The extract was also studied for antidiarrhoeal property using castor oil and MgSO(4)-induced diarrhoeal model, and charcoal induced gastrointestinal motility test in mice. At the doses of 200 and 400 mg/kg body weight, the extract reduced the frequency and severity of diarrhoea In test animals throughout the study period.
