Neutralizing and non-neutralizing antibodies to linear epitopes on HIV-1 envelope glycoproteins have potential mediate antiviral effector functions that could be beneficial vaccine-induced protection. Here, plasma IgG responses were assessed in three gp120 vaccine efficacy trials (RV144, Vax003, Vax004) HIV-1-infected individuals by using arrays of overlapping peptides spanning the entire consensus gp160 all major genetic subtypes circulating recombinant forms (CRFs) virus. In RV144, where...
ABSTRACT Background 3‐T MRI can improve image quality of fetal imaging compared to 1.5‐T MRI. However, concerns exist regarding increased local tissue heating at 3‐T. Purpose To assess radiofrequency (RF) safety by comparing simulated (using constant RF exposure) and simulating using exposures from clinical examinations. Study Type Retrospective. Population Seven voxelized anatomical pregnant body models (gestational age [GA] 30 ± 3 weeks [mean standard deviation], maternal mass index [BMI]...
Abstract Fetal health is critically dependent on placental function, especially transport of oxygen from mother to fetus. When fetal growth compromised, insufficiency must be distinguished modest genetic potential. If present, the physician trade off risk prolonged exposure against risks preterm delivery. Current ultrasound methods evaluate placenta are indirect and insensitive. We propose use Blood-Oxygenation-Level-Dependent (BOLD) MRI with maternal hyperoxia quantitatively assess mismatch...
Star-convex shapes arise across bio-microscopy and radiology in the form of nuclei, nodules, metastases, other units. Existing instance segmentation networks for such structures train on densely labeled instances each dataset, which requires substantial often impractical manual annotation effort. Further, significant reengineering or finetuning is needed when presented with new datasets imaging modalities due to changes contrast, shape, orientation, resolution, density. We present AnyStar, a...
Harnessing CD8+ T cell responses is being explored to achieve HIV remission. Although HIV-specific cells become dysfunctional without treatment, antiretroviral therapy (ART) partially restores their function. However, the extent of this recovery under long-term ART less understood.We analyzed differentiation status and function after initiated in acute or chronic infection ex vivo upon vitro recall.ART initiation any stage promoted persistence long-lived with high expansion (P<0·0008)...
Abstract In this work, it is demonstrated that a dual‐drive birdcage coil can be used to reduce the radiofrequency heating of metallic devices during magnetic resonance imaging. By controlling excitation currents two channels coil, current induced near lead tip could set zero. To monitor current, image artifacts tips were measured. The electric field distribution was controlled using coil. With method, and temperatures reduced substantially [<0.3°C for an applied 4.4 W/kg SAR compared...
Rigid motion tracking is paramount in many medical imaging applications where movements need to be detected, corrected, or accounted for.Modern strategies rely on convolutional neural networks (CNN) and pose this problem as rigid registration.Yet, CNNs do not exploit natural symmetries task, they are equivariant translations (their outputs shift with their inputs) but rotations.Here we propose EquiTrack, the first method that uses recent steerable SE(3)-equivariant (E-CNN) for tracking.While...
Myeloid activation contributes to cognitive impairment in chronic human immunodeficiency virus (HIV) infection. We explored whether combination antiretroviral therapy (cART) initiation during acute HIV infection impacts CD163 shedding, a myeloid marker, and turn, implications on the central nervous system (CNS). measured soluble (sCD163) levels plasma cerebrospinal fluid (CSF) by enzyme-linked immunosorbent assay Thais who initiated cART (Fiebig stages I–IV). Examination of CNS involvement...
Purpose To present a method for spatiotemporal alignment of in‐utero magnetic resonance imaging (MRI) time series acquired during maternal hyperoxia enabling improved quantitative tracking blood oxygen level‐dependent (BOLD) signal changes that characterize transport through the placenta to fetal organs. Materials and Methods The proposed pipeline images with single‐shot gradient echo echo‐planar includes 1) nonuniformity correction, 2) intravolume motion correction based on nonrigid...
Abstract Background Intestinal microbial dysbiosis is evident in chronic HIV-infected individuals and may underlie inflammation that persists even during antiretroviral therapy (ART). It remains unclear, however, how early after HIV infection gut emerges it affected by ART. Methods Fecal microbiota were studied 16s rDNA sequencing 52 Thai men who have sex with (MSM), at diagnosis of acute (AHI), Fiebig Stages 1–5 (F1-5), 6 months ART initiation, 7 MSM HIV-uninfected controls. Dysbiotic...
Matematik eğitiminin temel hedefi matematik bilgi ve becerilerinin kazandırılması, matematiğin gerçek hayattaki rolünün fark edilmesi amaç doğrultusunda eleştirel derin düşünebilen bireyler yetiştirilmesidir. okuryazarlığı, bireylerin bu beceri yetkinlikleri günlük yaşamlarında kullanabilmesidir matematiksel düşünmenin akıl yürütme, bağlantı kurma, modelleme, kavramların anlamlandırılması gibi yönlerini kapsamaktadır. Bu bize okuryazarı olabilmek için düşünme becerilerine sahip olunması...
Matematik eğitiminin temel amacı, bireylerin günlük hayatta karşılaştıkları problemlere çözüm bulabilmelerini sağlamaktır. Ancak okullarda, öğrencilerin matematiği nerelerde kullanacaklarına dair soru işaretleri bulunduğu gözlemlenmiştir. Bu soruya cevap verilse de öğretimde bu algının yeterince kullanılmaması bir sorun olarak öne çıkmaktadır. okuryazarlığı, matematiksel bilgi ve becerileri hayatlarında kullanabilmesidir. PISA sınavlarında Türkiye'nin başarısızlığının sebeplerinden biri,...
