Association of early sporulation genes with suggested developmental decision points in Streptomyces coelicolor A3(2)

Cytological analysis of a series of Streptomyces coelicolor A3(2) mutants with disruptions of early sporulation (whi, for white aerial mycelium) genes in an isogenic background has provided new information about the role of whiH, and confirmed and extended previous knowledge about whiG, whiA and whiB. The characteristic straight aerial hyphae of whiG mutants contained normally spaced vegetative-li

Instruments for assessing social support in social networks and in the self-management and rehabilitation process of persons poststroke : a scoping review protocol

Introduction As care and rehabilitation poststroke are increasingly moving into persons’ home environment, the importance of support from social networks in self-management and rehabilitation has emerged as an important topic for research and practice. While there are instruments used to assess social support and collective efficacy, a clearer scope of the availability and quality of these instrum

Generation of a non-sporulating strain of Streptomyces coelicolor A3(2) by the manipulation of a developmentally controlled ftsZ promoter

The differentiation of Streptomyces aerial hyphae into chains of unigenomic spores occurs through the synchronous formation of multiple FtsZ rings, leading to sporulation septa. We show here that developmental control of ftsZ transcription is required for sporulation in Streptomyces coelicolor A3(2). Three putative ftsZ promoters were detected in the ftsQ-ftsZ intergenic region. In addition, some

Charge-transfer properties and electron dynamics in ferromagnetic CoS2

We investigated the element-specific electronic structure and charge-carrier dynamics of a single-crystal ferromagnet CoS2 with complementary x-ray spectroscopy techniques. Hard x-ray photoemission (HAXPES) is used to provide crucial information on the bulk electronic structure and chemical bonding in CoS2 that is compared against the isoelectronic paramagnet CoSe2. The Co 1s core-level line shows

How Is Effort Defined in Communication Sciences and Disorders? A Systematic Review of Literature

Purpose: This systematic literature review aims to develop a comprehensive understanding of effort as a multidimensional construct in individuals with impaired swallowing and/or spoken communication. Method: A comprehensive literature search was conducted across three data-bases: PubMed/MEDLINE, Embase, and CINAHL, covering publications from 1966 to 2024. The search included terms related to commu

Concurrent Changes in Plasma Phosphorylated Tau 217, Tau PET, and Cognition in Preclinical Alzheimer Disease

Importance: Developing disease-modifying treatments is a priority for Alzheimer disease research. Objective: To determine the potential of plasma phosphorylated tau 217 (p-tau217) and tau positron emission tomography (PET) to assess disease modification in treatment trials. Design, Setting, and Participants: This diagnostic/prognostic study used longitudinal data from the Anti-Amyloid Treatment in

Probing Strangeness Hadronization with Event-by-Event Production of Multistrange Hadrons

This Letter presents the first measurement of event-by-event fluctuations of the net number (difference between the particle and antiparticle multiplicities) of multistrange hadrons Ξ- and Ξ¯+ and its correlation with the net-kaon number using the data collected by the ALICE Collaboration in pp, p-Pb, and Pb-Pb collisions at a center-of-mass energy per nucleon pair sNN=5.02 TeV. The statistical ha

Investigating Λ baryon production in p -Pb collisions in jets and the underlying event using angular correlations

First measurements of hadron-Λ (h-Λ) azimuthal angular correlations in p-Pb collisions at sNN =5.02 TeV using the ALICE detector at the Large Hadron Collider are presented. These correlations are used to separate the production of associated Λ baryons into three different kinematic regions, namely those produced in the direction of the trigger particle (near side), those produced in the opposite d

Individualism and working from home

We show that culturally transmitted individualism is an important determinant of working from home (WFH). Using individual-level data from the U.S. Current Population Survey (CPS) and the European Social Survey (ESS), we compare immigrants and their descendants from different cultural backgrounds residing in the same location. A 10-point increase in country-of-origin individualism (0–100 scale) in

Metabolic perturbations and ectopic fat deposition in men with low birth weight : Effects of a 4-week carbohydrate overfeeding challenge

Low birth weight (LBW) is a risk factor for type 2 diabetes (T2D). We hypothesized that 4 weeks of carbohydrate overfeeding (COF) with +25% energy would unmask key T2D perturbations among 22 nonobese LBW men, including five with screen-detected metabolic dysfunction-associated steatotic liver disease (MASLD), compared with 21 healthy control participants with normal birth weight (NBW). Body weight

LymphSens study : The enigma of subjective lymphoedema-how often and why do patients report lymphoedema after breast cancer treatment without an objective measurable swelling? the role of lymphatic and sensory processing problems: A protocol for a multicentre prospective longitudinal study

Introduction Breast cancer-related lymphoedema (BCRL) at the arm and/or trunk/breast is a highly feared complication following breast cancer treatment and can be objectified using the state-of-The-Art criteria based on volume, extracellular water ratio or skin thickness measurements. Although the incidence of objective BCRL is decreasing due to advances in breast cancer treatment, many patients re

Human cortical neurons rapidly generated by embryonic stem cell programming integrate into the stroke-injured rat cortex

Stem cell sources capable of producing appropriate cells for replacement will be necessary for functional repair of the injured brain. Here, we have determined whether transcription factor programming of human embryonic stem (hES) cells can be used to generate layer-specific cortical neurons capable of integrating into the stroke-injured rat cortex. Human embryonic stem cells were programmed via o

Adolescents’ experiences of psychological treatment for gaming disorder : a qualitative study

Background: Gaming disorder is a recently recognized psychiatric condition and a growing public health concern, particularly among adolescents. Despite this, there is limited research on what kind of treatment they need. Existing studies are mostly quantitative and offer limited insight into adolescents' lived experiences.Aim: The aim of this qualitative study is to explore how adolescent patientsBackground: Gaming disorder is a recently recognized psychiatric condition and a growing public health concern, particularly among adolescents.

Prostate-specific membrane antigen positron emission tomography/computed tomography imaging as a precision diagnostic at prostate cancer recurrence after radical prostatectomy : Modeling long-term survival

Background: Prostate-specific membrane antigen positron emission tomography/computed tomography (PSMA-PET/CT) is affecting the management of patients with prostate cancer with biochemical recurrence after radical prostatectomy. The long-term outcomes of tailoring salvage treatment on the basis of PSMA-PET/CT status remain to be determined. Methods: A decision-analytic model was developed to projec

Performance evaluation of a custom-designed contrast media injector in a 5-Tesla MRI environment

The compatibility and safety of contrast media injectors (CMIs) at ultra-high magnetic field strengths remains a critical challenge. This study aimed to investigate a custom-designed CMI powered by a ceramic motor in a newly developed 5T MRI environment, comparing it with a commercial CMI commonly used in a clinic. Three key performance aspects of the CMI were assessed in the 5T environment: trans
