Recently Discovered Pulsars and Unidentified Egret Sources
We present a correlative study between all unidentified EGRET sources at low Galactic latitudes and the newly discovered pulsars in the released portion of the Parkes multibeam radio survey. We note 14 positional coincidences: eight of these are “Vela-like” pulsars, with relatively small periods, small characteristic ages, and high spin-down luminosities. Three of these coincidences have been i...
متن کاملAbundances of Recently Discovered Planetary Nebulae
In this work we report spectrophotometric observations of a planetary nebula sample towards the galac-tic bulge. A total of 45 PNe was observed and their physical parameters (electron density and temperature) were derived. Ionic abundances were calculated using a three-level atom model and abundances were derived through ionisation correction factors. Results show low abundance objects at high ...
متن کاملNeuroinvasion by human respiratory coronaviruses.
Human coronaviruses (HCoV) cause common colds but can also infect neural cell cultures. To provide definitive experimental evidence for the neurotropism and neuroinvasion of HCoV and its possible association with multiple sclerosis (MS), we have performed an extensive search and characterization of HCoV RNA in a large panel of human brain autopsy samples. Very stringent reverse transcription-PC...
متن کاملBiological Activity of Recently Discovered Halogenated Marine Natural Products
This review presents the biological activity-antibacterial, antifungal, anti-parasitic, antiviral, antitumor, antiinflammatory, antioxidant, and enzymatic activity-of halogenated marine natural products discovered in the past five years. Newly discovered examples that do not report biological activity are not included.
متن کاملRecently discovered T cell subsets cannot keep their commitments.
After activation by antigen/MHC (signal 1) and CD28-dependent co-stimulation (signal 2), resting CD4(+) T cells commit to one of a variety of functionally and molecularly defined phenotypes. Two long established CD4 phenotypes, Th1 and Th2 cells, have been regarded as terminally differentiated formats. Recently, two additional phenotypes, tissue-protective regulatory (Tregs) and tissue-destruct...
