On the Universality of Jordan Centers for Estimating Infection Sources in Tree Networks [PDF]

open access: yes, 2014
Finding the infection sources in a network when we only know the network topology and infected nodes, but not the rates of infection, is a challenging combinatorial problem, and it is even more difficult in practice where the underlying infection spreading model is usually unknown a priori. In this paper, we are interested in finding a source estimator

Prefrontal FGF1 Signaling is Required for Accumbal Deep Brain Stimulation Treatment of Addiction

open access: yesAdvanced Science, EarlyView.
This research delineates that a cortical‐accumbal pathway and local FGF1 signaling in the medial prefrontal cortex are critical for NAc‐DBS to be effective in altering morphine CPP. These findings demonstrate a top‐down motif to regulate the therapeutic effects of subcortical DBS on addiction and support the potential for addiction treatments involving

Secondary infections worsen the outcome of COVID‐19 in patients with hematological malignancies: A report from the ITA‐HEMA‐COV

open access: yesHematological Oncology, Volume 40, Issue 5, Page 846-856, December 2022., 2022
Abstract The impact of secondary infections (SI) on COVID‐19 outcome in patients with hematological malignancies (HM) is scarcely documented. To evaluate incidence, clinical characteristics, and outcome of SI, we analyzed the microbiologically documented SI in a large multicenter cohort of adult HM patients with COVID‐19.

Confinement by Liquid‐Liquid Interface Replicates In Vivo Neutrophil Deformations and Elicits Bleb‐Based Migration

open access: yesAdvanced Science, EarlyView.
Leukocytes sense mechanical cues provided by surrounding cells to regulate motility. Replicating the confining pressures applied by soft, elastic tissues in vitro is challenging. Here, the use of liquid‐liquid interfaces is introduced to model forces exerted by surrounding cells. Confining pressures are tunable by controlling interfacial curvature, and

Associations between early‐life and in utero infections and cytomegalovirus‐positive acute lymphoblastic leukemia in children

open access: yesInternational Journal of Cancer, Volume 152, Issue 5, Page 845-853, 1 March 2023., 2023
What's new? Cytomegalovirus (CMV) infection early in life likely contributes to the development of childhood acute lymphoblastic leukemia (ALL), owing to CMV‐induced alterations in immune function. In the present study, the relationship between risk of childhood ALL and exposure to CMV in utero or early life was investigated among children with ALL who

No association between islet cell antibodies and coxsackie B, mumps, rubella and cytomegalovirus antibodies in non-diabetic individuals aged 7–19 years [PDF]

open access: yes, 1991
Viral antibodies were tested in a cohort of 44 isletcell antibody-positive individuals age 7–19 years, and 44 of their islet cell antibody-negative age and sex-matched classmates selected from a population study of 4208 pupils who had been screened for ...

Spatially dense stochastic epidemic models with infection-age dependent infectivity [PDF]

open access: yesarXiv, 2023
We study an individual-based stochastic spatial epidemic model where the number of locations and the number of individuals at each location both grow to infinity. Each individual is associated with a random infection-age dependent infectivity function. Individuals are infected through interactions across the locations with heterogeneous effects.

CXCL13 Damages Blood Spinal Cord Barrier by Promoting RNF6/Sqstm1‐Ubiquitination Induced Autophagy in Experimental Allergic Encephalomyelitis

open access: yesAdvanced Science, EarlyView.
In multiple sclerosis, the disruption of the blood‐spinal cord barrier (BSCB) induced by CXCL13 facilitates the infiltration of inflammatory cells into the central nervous system, resulting in demyelination and neuronal injury. Mechanistically, the deleterious impact of CXCL13 on the BSCB is associated with a reduction in tight junction protein ...

Neutralizing Monoclonal Antibodies Reduce Human Cytomegalovirus Infection and Spread in Developing Placentas. [PDF]

open access: yes, 2019
Congenital human cytomegalovirus (HCMV) infection is a leading cause of birth defects worldwide, yet the most effective strategies for preventing virus transmission during pregnancy are unknown.

A re-entrant phase transition in the survival of secondary infections on networks [PDF]

open access: yes, 2018
We study the dynamics of secondary infections on networks, in which only the individuals currently carrying a certain primary infection are susceptible to the secondary infection. In the limit of large sparse networks, the model is mapped to a branching process spreading in a random time-sensitive environment, determined by the dynamics of the ...
