Protective immunity against Mycobacterium tuberculosis requires CD4+ lymphocyte-mediated immune responses and IFN-gamma activity. As the primary portal of entry of M. tuberculosis is the lung, pulmonary immune responses against multiple M. tuberculosis Ags were compared between both M. tuberculosis-exposed tuberculin skin test-positive healthy household contacts (HHC) of patients with active sp...

Gamma-band peaks in the power spectrum of local field potentials (LFP) are found in multiple brain regions. It has been theorized that gamma oscillations may serve as a 'clock' signal for the purposes of precise temporal encoding of information and 'binding' of stimulus features across regions of the brain. Neurons in model networks may exhibit periodic spike firing or synchronized membrane pot...

The level of interferon-gamma (IFN-gamma) in pleural fluid has been reported to be increased in pleural tuberculosis. Nevertheless, its diagnostic value has not yet been well-established, and immunocompromised patients have not previously been evaluated. The aim of this study was to determine the value of the IFN-gamma level in pleural fluid for diagnosing tuberculous pleurisy in immunocompeten...

R. H. Whittaker's idea that plant diversity can be divided into a hierarchy of spatial components from alpha at the within-habitat scale through beta for the turnover of species between habitats to gamma along regional gradients implies the underlying existence of alpha, beta, and gamma niches. We explore the hypothesis that the evolution of alpha, beta, and gamma niches is also hierarchical, w...

The aim of this study was to test the hypothesis that a reinforced gamma nail for the fixation of subtrochanteric fractures would experience less stress during loading compared with a common gamma nail. The issue of whether the use of the stronger implant would result in more stress shielding in the surrounding bone was also addressed. A finite element analysis (FEA) of a synthetic bone was emp...

Antigens recognized by anti-gamma-seminoprotein (gamma-Sm) antibody and anti-prostate-specific antigen (PA) antibody were analyzed immunologically by Ouchterlony method and Western blotting method. The double immunodiffusion test demonstrated that anti-gamma-Sm antibody and anti-PA antibody reacted against an identical antigen in seminal fluid or prostate homogenate. In the immunoblotting exami...

The gamma density function is usually defined in interval between zero and infinity. This paper introduces an upper and a lower boundary to this distribution. The parameters which characterize the truncated gamma distribution are evaluated. A statistical test is performed on two samples of stars. A comparison with the lognormal and the four power law distribution is made.

To explain gating of memory encoding, magnetoencephalography (MEG) was analyzed over multi-regional network of negative correlations between alpha band power during cue (cue-alpha) and gamma band power during item presentation (item-gamma) in Remember (R) and No-remember (NR) condition. Persistent homology with graph filtration on alpha-gamma correlation disclosed topological invariants to expl...

Erythroid Krüppel-like factor (EKLF), an erythroid tissue-specific Krüppel-type zinc finger protein, binds to the beta-globin gene CACCC box and is essential for beta-globin gene expression. EKLF does not activate the gamma gene, the CACCC sequence of which differs from that of the beta gene. To test whether the CACCC box sequence difference is the primary determinant of the selective activatio...
