Structural and Functional Characterization of EXPO‐Derived Extracellular Vesicles in Plants

Advanced Science, EarlyView.
In this study, 3D electron tomography (ET), cryo‐ET, and immunogold transmission electron microscopy (TEM) are employed to characterize plant extracellular vesicles (EVs) under physiological conditions. EVs are classified into three distinct categories according to their size, content, and molecular‐marker profiles. Furthermore, Exo70E2‐positive medium

Differential expression of dnaA and dosR genes among members of the Mycobacterium tuberculosis complex under oxic and hypoxic conditions [PDF]

, 2010
Major differences regarding the pathology and host immune response of the Beijing and Canettii genotypes of Mycobacterium tuberculosis have been reported; however, studies on the genetic expression of these genotypes during in vitro dormancy are scarce ...

A robust SNP barcode for typing Mycobacterium tuberculosis complex strains [PDF]

, 2014
Strain-specific genomic diversity in the Mycobacterium tuberculosis complex (MTBC) is an important factor in pathogenesis that may affect virulence, transmissibility, host response and emergence of drug resistance.

Tuberculosis Relapse in Vietnam Is Significantly Associated With Mycobacterium tuberculosis Beijing Genotype Infections [PDF]

The Journal of Infectious Diseases, 2013
In Vietnam, the Mycobacterium tuberculosis Beijing genotype is associated with multi-drug resistance and is emerging. A possible explanation for this genotype's success is an increased rate of relapse.In a prospective cohort study, isolates from patients with smear-positive tuberculosis were subjected to drug susceptibility testing and to spoligotyping

PD‐1 Inhibits CD4+ TRM‐Mediated cDC1 Mobilization via Suppressing JAML in Human NSCLC

Advanced Science, EarlyView.
CD4+ tissue‐resident memory T cells (TRMs) in non‐small cell lung cancer recruit conventional type 1 dendritic cells via XCL1‐XCR1 signaling, orchestrating antitumor immunity. The costimulatory molecule JAML is essential for this process. PD‐1 blockade restores JAML expression and cDC1 mobilization, while JAML agonists synergize with anti‐PD‐1 therapy,

Comparative susceptibility of mosquito populations in North Queensland, Australia to oral infection with dengue virus. [PDF]

, 2014
Dengue is the most prevalent arthropod-borne virus, with at least 40% of the world's population at risk of infection each year. In Australia, dengue is not endemic, but viremic travelers trigger outbreaks involving hundreds of cases.

Mycobacterium tuberculosis Beijing Genotype and Mycobacterial Interspersed Repetitive Unit Typing [PDF]

Journal of Clinical Microbiology, 2006
Rao et al. ([3][1]) described a method to identify Mycobacterium tuberculosis strains of the Beijing genotype. The authors suggested using simple PCR of mycobacterial interspersed repetitive unit-variable-number tandem repeat (MIRU-VNTR) locus 26 to identify these strains.

TheMycobacterium tuberculosisBeijing Genotype Does Not Affect Tuberculosis Treatment Failure in Vietnam [PDF]

Clinical Infectious Diseases, 2010
Studies have suggested that the Mycobacterium tuberculosis Beijing genotype causes more severe clinical disease and higher treatment failure rates with standard regimens, possibly in association with an increased risk of acquiring drug resistance.

Ratoon Season Rice Reduces Methane Emissions by Limiting Acetic Acid Transport to the Rhizosphere and Inhibiting Methanogens

Advanced Science, EarlyView.
This study finds that the interaction between ABA‐OsCIPK2‐OsSWEET1A reduces the allocation of methane producing bacteria carbon source (acetic acid) content to the rhizosphere soil of ratoon season rice, thereby reducing methane emissions. Abstract Rice paddies are a major, persistent source of atmospheric methane (CH4), emission rates depend on the ...
