The MR images of 185 patients (103 males, 82 females) with glioblastoma multiforme were downloaded from The Cancer Imaging Archive (TCIA) to test the tumor segmentation performance of this software. Regions of interest (ROIs) corresponding to contrast-enhancing lesions, necrotic portions, and non-enhancing T2 high signal intensity components were segmented for each tumor.

Broadly neutralizing antibodies and monoclonal V2 antibodies derived from RV305 inhibit capture and replication of HIV-1.

An important approach to stopping the AIDS epidemic is the development of a vaccine that elicits antibodies that block virus capture, the initial interactions of HIV-1 with the target cells, and replication. We utilized a previously developed qRT-PCR-based assay to examine the effects of broadly neutralizing antibodies (bNAbs), plasma from vaccine trials, and monoclonal antibodies (mAbs) on virus capture and replication. A panel of bNAbs inhibited primary HIV-1 replication in PBMCs but not virus capture.

MAdCAM-1 co-stimulation combined with retinoic acid and TGF-β induces blood CD8 T cells to adopt a gut CD101 T phenotype.

Resident memory T cells (Ts) help control local immune homeostasis and contribute to tissue-protective immune responses. The local cues that guide their differentiation and localization are poorly defined. We demonstrate that mucosal vascular addressin cell adhesion molecule 1, a ligand for the gut-homing receptor αβ integrin, in the presence of retinoic acid and transforming growth factor-β (TGF-β) provides a co-stimulatory signal that induces blood cluster of differentiation (CD8 T cells to adopt a T-like phenotype.

Skin pharmacokinetics of miltefosine in the treatment of post-kala-azar dermal leishmaniasis in South Asia.

Joubert syndrome presenting bilateral peroneal neuropathies: A case report.

Rationale: Joubert syndrome (JS) is a rare genetic disorder that presents with various neurological symptoms, primarily involving central nervous system dysfunction. Considering the etiology of JS, peripheral nervous system abnormalities cannot be excluded; however, cases of JS accompanied by peripheral nervous system abnormalities have not yet been reported. Distinct radiological findings on brain magnetic resonance imaging were considered essential for the diagnosis of JS.

Antigenic distance between primary and secondary dengue infections correlates with disease risk.

Many pathogens continuously change their protein structure in response to immune-driven selection, resulting in weakened protection even in previously exposed individuals. In addition, for some pathogens, such as dengue virus, poorly targeted immunity is associated with increased risk of severe disease through a mechanism known as antibody-dependent enhancement. However, it remains unclear whether the antigenic distances between an individual's first infection and subsequent exposures dictate disease risk, explaining the observed large-scale differences in dengue hospitalizations across years.
