Clinical and dosimetric outcomes of a 3-fraction high-dose-rate brachytherapy boost for the treatment of locally advanced cervical cancer in a safety net hospital.

Purpose: To report outcomes of a 3-fraction HDR brachytherapy boost for the treatment of locally advanced cervical cancer (LACC) at a large safety net hospital.

Methods And Materials: A retrospective review of 93 patients with FIGO 2018 Stage IA2 to IVB cervical cancer treated with HDR brachytherapy boost in 3 fractions between 2017 and 2022 was conducted. The 2-year local control (LC), progression-free survival (PFS), and overall survival (OS) was estimated using Kaplan-Meier estimators.

Butyrate limits inflammatory macrophage niche in NASH.

Immune cell infiltrations with lobular inflammation in the background of steatosis and deregulated gut-liver axis are the cardinal features of non-alcoholic steatohepatitis (NASH). An array of gut microbiota-derived metabolites including short-chain fatty acids (SCFA) multifariously modulates NASH pathogenesis. However, the molecular basis for the favorable impact of sodium butyrate (NaBu), a gut microbiota-derived SCFA, on the immunometabolic homeostasis in NASH remains elusive.

Theragnostic application of nanoparticle and CRISPR against food-borne multi-drug resistant pathogens.

Foodborne infection is one of the leading sources of infections spreading across the world. Foodborne pathogens are recognized as multidrug-resistant (MDR) pathogens posing a significant problem in the food industry and healthy consumers resulting in enhanced economic burden, and nosocomial infections. The continued search for enhanced microbial detection tools has piqued the interest of the CRISPR-Cas system and Nanoparticles.

Automatic segmentation of high-risk clinical target volume for tandem-and-ovoids brachytherapy patients using an asymmetric dual-path convolutional neural network.

Purposes: Preimplant diagnostic magnetic resonance imaging is the gold standard for image-guided tandem-and-ovoids (T&O) brachytherapy for cervical cancer. However, high dose rate brachytherapy planning is typically done on postimplant CT-based high-risk clinical target volume (HR-CTV ) because the transfer of preimplant Magnetic resonance (MR)-based HR-CTV (HR-CTV ) to the postimplant planning CT is difficult due to anatomical changes caused by applicator insertion, vaginal packing, and the filling status of the bladder and rectum. This study aims to train a dual-path convolutional neural network (CNN) for automatic segmentation of HR-CTV on postimplant planning CT with guidance from preimplant diagnostic MR.

An ERP study of cross-modal rhyming: Influences of phonology and orthography.

In a cross-modal rhyming study with visual pseudoword primes and auditory word targets, we found a typical ERP rhyming effect such that nonrhyming targets elicited a larger N400/N450 than rhyming targets. An orthographic effect was also apparent in the same 350- to 600-ms epoch as the phonological effect: The rhyming effect for targets with rime orthography that did not match their primes' (e.g.

Masked priming and ERPs dissociate maturation of orthographic and semantic components of visual word recognition in children.

This study examined the time-course of reading single words in children and adults using masked repetition priming and the recording of event-related potentials. The N250 and N400 repetition priming effects were used to characterize form- and meaning-level processing, respectively. Children had larger amplitude N250 effects than adults for both shorter and longer duration primes.

Multimodality approach to management of stage III non-small cell lung cancer.

Stage III non-small cell lung cancer represents a heterogeneous group of patients who are best managed with a multidisciplinary approach, including evaluation for surgical, radiation, and chemotherapeutic options.

Imagining the truth and the moon: an electrophysiological study of abstract and concrete word processing.

Previous event-related potential studies have indicated that both a widespread N400 and an anterior N700 index differential processing of concrete and abstract words, but the nature of these components in relation to concreteness and imagery has been unclear. Here, we separated the effects of word concreteness and task demands on the N400 and N700 in a single word processing paradigm with a within-subjects, between-tasks design and carefully controlled word stimuli. The N400 was larger to concrete words than to abstract words, and larger in the visualization task condition than in the surface task condition, with no interaction.

Behavioral and ERP evidence of word and pseudoword superiority effects in 7- and 11-year-olds.

In groups of 7-year-olds and 11-year-olds, event-related potentials (ERPs) were recorded to briefly presented, masked letter strings that included real word (DARK/PARK), pronounceable pseudoword (DARL/PARL), unpronounceable nonword (RDKA/RPKA), and letter-in-xs (DXXX, PXXX) stimuli in a variant of the Reicher-Wheeler paradigm. Behaviorally, participants decided which of two letters occurred at a given position in each string (here, forced-choice alternatives D and P). Both groups showed evidence of behavioral word (more accurate choices for letters in words than in baseline nonwords or letter-in-xs) and pseudoword (more accurate choices for letters in pseudowords than in baseline nonwords or letter-in-xs) superiority effects.

Letters rhyme: electrophysiological evidence from children and adults.

Event-related potentials (ERPs) and behavioral accuracy judgments were recorded in a letter name rhyming paradigm (e.g., A-J versus A-B) with 6- to 8-year-old beginning readers and adults.

Clinical evaluation of soft tissue organ boundary visualization on cone-beam computed tomographic imaging.

Purpose: Cone-beam computed tomographic images (CBCTs) are increasingly used for setup correction, soft tissue targeting, and image-guided adaptive radiotherapy. However, CBCT image quality is limited by low contrast and imaging artifacts. This analysis investigates the detectability of soft tissue boundaries in CBCT by performing a multiple-observer segmentation study.

Word and pseudoword superiority effects reflected in the ERP waveform.

A variant of the Reicher-Wheeler task was used to determine when in the event-related potential (ERP) waveform indices of word and pseudoword superiority effects might be present, and whether ERP measures of superiority effects correlated with standardized behavioral measures of orthographic fluency and single word reading. ERPs were recorded to briefly presented, masked letter strings that included real words (DARK/PARK), pseudowords (DARL/PARL), nonwords (RDKA/RPKA), and letter-in-xs (DXXX, PXXX) stimuli. Participants decided which of two letters occurred at a given position in the string (here, forced-choice alternatives D and P).

A masked priming ERP study of letter processing using single letters and false fonts.

Previous event-related potential (ERP) research on letter processing has suggested that a P150 reflects low-level, featural processing, whereas a P260 reflects high-level, abstract letter processing. In order to investigate the specificity of these effects, ERPs were recorded in a masked priming paradigm using matching and nonmatching pairs of letters (e.g.

Three kinds of rhymes: An ERP study.

In a simple prime-target visual rhyming paradigm, pairs of words, nonwords, and single letters elicited similar event-related potential (ERP) rhyming effects in young adults. Within each condition, primes elicited contingent negative variation (CNV) while nonrhyming targets elicited more negative waveforms than rhyming targets within the 320-500ms (N400/N450) time window. The target rhyming effect, apparently primarily an index of phonological processing, was similar across conditions but tended to be smaller in mean amplitude for letters.

Intraoral manganese superoxide dismutase-plasmid/liposome (MnSOD-PL) radioprotective gene therapy decreases ionizing irradiation-induced murine mucosal cell cycling and apoptosis.

Background: Single or multiple intraoral administrations of manganese superoxide dismutase-plasmid/liposomes (MnSOD-PL) to C3H/HeNHsd mice receiving single fraction or fractionated ionizing irradiation to the head and neck region have been shown to significantly decrease mucosal ulceration, weight loss and to improve survival.

Materials And Methods: To elucidate the mechanism of irradiation protection by MnSOD-PL and explore possible additive or synergistic protective effects with Amifostine (WR2721), mice received a single fraction of 19, 22.5, 25 or 30 Gy, or 24 fractions of 3 Gy irradiation to the oral cavity and oropharynx.
