Pathogenesis of Providencia alcalifaciens-induced diarrhea [PDF]

Infection and Immunity, 1992
Providencia alcalifaciens is a member of the family Enterobacteriaceae. There are reports that P. alcalifaciens can cause diarrhea, but the mechanism(s) by which it causes diarrhea is known. We studied P. alcalifaciens isolated from a child and two adults with diarrhea for enteropathogenicity.

Molecular basis of antibiotic sensing by the TetR family regulator CecR – a structural perspective

The FEBS Journal, EarlyView.
Escherichia coli CecR, a member of the TetR family regulators, senses selected antibiotics and activates the expression of a putative drug efflux pump. Although present in many pathogenic Enterobacteriales strains, CecR remains poorly characterized. We present the first CecR crystal structure, which reveals a unique tunnel‐like ligand‐binding cavity ...

Physical Performance and its Association with Executive Function in Latin American Older Adults: Evidence from the LatAmFINGERS Multicenter Randomized Controlled Trial

Alzheimer's &Dementia, Volume 21, Issue S6, December 2025.
Abstract Background The accelerated aging process in low‐ and middle‐income countries (LMIC) has led to an increased prevalence of non‐communicable diseases, including dementia, a leading cause of disability in Latin America and the Caribbean (LAC). Executive and physical performance dysfunction accelerates functional decline in older adults.

Note on the Minimum Weight States in the su(2)-Algebraic Many-Fermion Model --- Extension of the Role of the Auxiliary su(2)-Algebra ---

, 2011
The role of the auxiliary su(2)-algebra proposed by the present authors in the latest paper is extended. Its aim is to determine the minimum weight states completely.

Deformed Boson Scheme in Time-Dependent Variational Method. I [PDF]

, 2001
Various aspects of the deformed boson scheme are investigated with aiming of applying to the time-dependent variational method for many-boson system. The case of the multiboson states is also discussed.

A Role of the Quasiparticle in the Conservation of the Fermion Number

, 2012
The role of the "quasiparticle" introduced in last paper by the present authors is discussed. It serves as a guide for the deformation of the Cooper-pair in the BCS-Bogoliubov approach. As an illustrative example, a certain case is treated.

Spin polarization in high density quark matter under a strong external magnetic field [PDF]

, 2016
In high density quark matter under a strong external magnetic field, possible phases are investigated by using the two-flavor Nambu-Jona-Lasinio model with tensor-type four-point interaction between quarks, as well as the axial-vector-type four-point ...

A Note on the Eigenvalue Problem in the su(1,1)-Algebra

, 2004
Normalization constant in the eigenstate appearing in the eigenvalue problem of the su(1,1)-algebra is discussed. This normalization constant is expressed in terms of the Gauss' hypergeometric series which is not absolutely convergent.
