The objective of this study was to extract, characterize, and examine the antibacterial properties orange essential oil obtained from citrus sinensis peels, using hydro-distillation method. Various components were characterized by FTIR, UV-Vis GC- MS spectroscopic techniques. extracted conformed AFNOR standards, had a maximum yield 3.4% (w/w). results showed that limonene major bioactive (97.14...

In this work we generalize the idea of a gravitational phase transition or GPT at late times to allow for modified gravity scenario in early universe as well. The original was shown simultaneously relax $H_0$ and $\sigma_8$ tensions {\it Planck} internal inconsistencies. However, primary results from predictions implied disagreement with data baryonic acoustic oscillations (BAO). Here investiga...

PURPOSE We investigated whether oxygen-induced retinopathy (OIR) results in changes in the protein expression of neuronal and inducible nitric oxide synthases (nNOS and iNOS, respectively) in rat model of OIR. In addition, we evaluated whether treatment of rats with triamcinolone acetonide (TA) prevents this response. METHODS To promote OIR, Sprague-Dawley rats were exposed to hyperoxia from ...

PURPOSE Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) represent a heterogeneous disease group originating from the neuroendocrine cells. Identification of prognostic markers, related to neuroendocrine tissue-selective tumorigenesis, is necessary to find therapeutic targets. MATERIALS AND METHODS A total of 327 patients with GEP-NETs were included in this study; there were 49 gastric...

Digestive fluid of the araneid spider Argiope aurantia is known to contain zinc metallopeptidases. Using anion-exchange chromatography, size-exclusion chromatography, sucrose density gradient centrifugation, and gel electrophoresis, we isolated two lower-molecular-mass peptidases, designated p16 and p18. The N-terminal amino acid sequences of p16 (37 residues) and p18 (20 residues) are 85% iden...

During primary viral infection, in vivo exposure to high doses of virus causes a loss of Ag-specific CD8(+) T cells. This phenomenon, termed clonal exhaustion, and other mechanisms by which CTLs are deleted are poorly understood. Here we show evidence for a novel form of cell death in which recently stimulated CD8(+) HIV-1 envelope gp160-specific murine CTLs become apoptotic in vitro after brie...

This study aimed to investigate the effects of abundant breast milk intake on rats model of oxygen-induced retinopathy (OIR). Neonatal Sprague-Dawley rats were randomly assigned to expand litters of 7 pups/litter (7-rats group) and 14 pups/litter (14-rats group). They were exposed to 80% oxygen from postnatal day (P) 0 to P12. Body weights were measured daily. At P13 and 18, rats were sacrifice...
