Collisions of Jets of Particles from Active Galactic Nuclei with Neutralino Dark Matter

open access: yes, 2013
We examine the possibility that energetic Standard Model particles contained in the jets produced by active galactic nuclei (AGN) may scatter off of the dark matter halo which is expected to surround the AGN.

Tensor-Induced CMB Temperature-Polarization Correlation in Reionized Universes [PDF]

open access: yes, 1999
We reexamine the temperature-polarization correlation function of the cosmic microwave background induced by tensor mode with a scale-invariant spectrum in reionized standard cold dark matter models.

Mineral‐targeted alkaline phosphatase improves bone graft‐mediated alveolar bone defect healing in mice

open access: yesJournal of Periodontology, EarlyView.
Abstract Background Alveolar bone loss challenges tooth retention and implant placement. Freeze‐dried bone allograft (FDBA) is widely used for alveolar ridge preservation but has limitations in resorption rate and healing time. In this proof‐of‐concept study, we tested whether pro‐mineralization enzyme, tissue‐nonspecific alkaline phosphatase (TNAP ...

Lepton-Flavor Violation with Non-universal Soft Terms [PDF]

open access: yes, 2001
We study the lepton-flavor violation processes tau ->mu gamma and mu->e gamma in two different examples of models with non-universal soft breaking terms derived from strings.

Resolving Endoplasmic Reticulum‐Protein Misfolding Restores Corticosteroid Sensitivity in Experimental Models of Severe Asthma

open access: yesAllergy, EarlyView.
This study investigates the role of ER stress in steroid resistance in severe asthma. Results from advanced 3D models of human bronchial epithelial cells, steroid‐resistant severe asthma mouse models, and human severe asthma sputum samples show that treatment with ICS in combination with the ER stress inhibitor 4‐PBA significantly enhances steroid ...

Titanium alloys (AoN) and their involvement in osseointegration

open access: yesDental Research Journal, 2012
Background: Osseointegration is essential for a long-term successful and inflammation-free dental implant. Such a result depends on osteoblastic cells growth and differentiation at the tissue-implant interface.

Targeted Alkaline Phosphatase Therapy Enhances Alveolar Bone Healing in X‐Linked Hypophosphatemia in Mice

open access: yesJournal of Periodontal Research, EarlyView.
Effects of exogenous tissue‐nonspecific alkaline phosphatase (TNAP) were analyzed in the Hyp mouse model of X‐linked hypophosphatemia (XLH). Maxillary first molars were extracted from wild‐type (WT) and Hyp mice at 6 weeks, and collagen gel ± TNAP was placed in sockets. In one group of Hyp mice, submucosal injections of TNAP or saline were delivered at

Crises in a dissipative Bouncing ball model [PDF]

open access: yes, 2015
The dynamics of a bouncing ball model under the influence of dissipation is investigated by using a two dimensional nonlinear mapping. When high dissipation is considered, the dynamics evolves to different attractors.

Genetic risk variants implicate impaired maintenance and repair of periodontal tissues as causal for periodontitis—A synthesis of recent findings

open access: yesPeriodontology 2000, EarlyView.
AbstractPeriodontitis is a complex inflammatory disease in which the host genome, in conjunction with extrinsic factors, determines susceptibility and progression. Genetic predisposition is the strongest risk factor in the first decades of life. As people age, chronic exposure to the periodontal microbiome puts a strain on the proper maintenance of ...
