Same RTs to pairs of letters or other patterns are often faster than different RTs. This finding has led to hypothesize a two-process system of comparison: a fast holistic process for same and a slower analytic process for different responses. In connection with hemispheric specialization, RH has been characterized as a holistic and LH as an analytic processor. Therefore same responses should be mediated by RH and different responses by LH. In the present study, subjects made same-different judgments in the two visual fields to successively presented pairs of letters where degree of difference was systematically varied. RTs decreased with increases in the degree of difference in different responses. Same responses were faster than different. These results suggest analytic processing of different and holistic processing of same pairs. Since no clear-cut visual field superiority was found, the conclusion is that both hemispheres can process visual information analytically and holistically.

Richter syndrome (RS), characterized by aggressive lymphoma arising from chronic lymphocytic leukaemia (CLL), presents a poor response to treatment and grim prognosis. To elucidate RS mechanisms, paired samples from a patient with DLBCL-RS were subjected to single-cell RNA sequencing (scRNA-seq) and high-throughput chromosome conformation capture (Hi-C) sequencing. Over 10,000 cells were profiled via scRNA-seq, revealing the comprehensive B cell transformation in RS.

Background: Despite efforts to promote optimal breastfeeding practices, the practice of exclusive breastfeeding is low in South Africa. We conducted a trial to determine whether text messaging plus motivational interviewing prolonged exclusive breastfeeding during the first six months of life and improved child health outcomes.
Methods: We conducted a randomized parallel group-controlled trial between July 2022 and May 2024, at a secondary-level healthcare facility.

Context: Clinical Practice Guidelines from the Consortium for Spinal Cord Injury (SCI) Medicine recommend daily self-screening of at-risk skin surfaces, but many Veterans with SCI describe challenges using the standard issue long-handled self-inspection mirror (LSIM).
Objective: The objective of this project was to compare the LSIM to a recently developed camera-based self-inspection system (CSIS). User feedback guided iterative engineering to improve and develop the new technology in preparation for transfer to industry.

Early spelling depends on the ability to understand the alphabetic principle and to translate speech sounds into visual symbols (letters). Thus, the ability to associate sound-symbol pairs might be an important predictor of spelling development. Here, we examined the relation between sound-symbol learning (SSL) and early spelling skills.
