Ribosomes exist in large excess over the apparent demand for protein synthesis during carbon starvation in marine Vibrio sp. strain CCUG 15956

Carbon starvation induces the development of a starvation- and stress- resistant cell state in marine Vibrio sp. strain S14 (CCUG 15956). The starved cells remain highly responsive to nutrients during prolonged starvation and exhibit instantaneous severalfold increases in the rates of protein synthesis and RNA synthesis when substrate is added. In order to elucidate the physiological basis for the

Responses to multiple-nutrient starvation in marine Vibrio sp. strain CCUG 15956

The response of marine Vibrio sp. strain S14 (CCUG 15956) to long-term (48-h) multiple-nutrient starvation (i.e., starvation for glucose, amino acids, ammonium, and phosphate simultaneously) can be described as a three-phase process. The first phase, defined as the stringent control phase, encompasses an accumulation of guanosine 5'-diphosphate 3'-diphosphate (ppGpp) and decreases in RNA and prote

Updated Appropriate Use Criteria for Amyloid and Tau PET : A Report from the Alzheimer’s Association and Society for Nuclear Medicine and Molecular Imaging Workgroup

The Alzheimer’s Association and the Society of Nuclear Medicine and Molecular Imaging convened a multidisciplinary workgroup to update appropriate use criteria (AUC) for amyloid positron emission tomography (PET) and to develop AUC for tau PET. Methods: The workgroup identified key research questions that guided a systematic literature review on clinical amyloid/tau PET. Building on this review, t

Experimental Study of Glow Plug Assisted Methanol Compression Ignition

Methanol can be produced renewably and used in compression ignition (CI) engines as a replacement for fossil diesel. However, methanol is a low cetane fuel, creating challenges in achieving stable operation, particularly at low load. One potential solution is through surface ignition via a glow plug. In this work, experiments were conducted on a methanol-fueled 2.1 L single cylinder engine instrum

Hot Rocks Survey : II. the thermal emission of TOI-1468 b reveals a bare hot rock

Context. Terrestrial exoplanets orbiting nearby small cool stars, known as M dwarfs, are well suited for an atmospheric characterisation. Because the intense X-ray and UV (XUV) irradiation from M dwarf host stars is strong, orbiting exoplanets are thought to be unable to retain primordial hydrogen- or helium-dominated atmospheres. However, it is currently unknown whether heavier secondary atmosphe

A coiled-coil domain triggers oligomerization of MmpL10, the mycobacterial transporter of trehalose polyphleate precursor

The mycobacterial outer membrane is composed of unusual lipids and glycolipids. Some of these lipids are exported to the cell envelope by resistance-nodulation-division (RND) transporters called mycobacterial membrane protein large (MmpL). While the oligomeric state of most RND transporters is well established, MmpL assembly remains unclear. Here, we investigated MmpL10, the trehalose polyphleate

Highlighting Migration in Dermatology : Population Characteristics among Patients Seen in a Dermatological Out-Patient Clinic in Southern Sweden

Introduction: Migration is an increasing phenomenon and associated with a physical and psychosocial burden on individuals. Little is known about migration and skin health. The objective of this study was to describe the characteristics of patients regarding migration background and dermatological morbidity among adults seen in a dermatological out-patient clinic in Malmö, Sweden. Methods: An obser

Clinical usefulness of tools used for screening and measuring frailty in the ambulance and emergency department in older people : a scoping review protocol

INTRODUCTION: As people age, frailty becomes increasingly prevalent and is associated with adverse outcomes, including higher risks of hospitalisation, institutionalisation and mortality. Early identification of frailty in ambulance and emergency department (ED) settings may support clinical decision-making and help predict outcomes for older patients. However, there is currently no consensus on h

Challenges in the future of cancer screening

The purpose of cancer screening is to reduce mortality, and ideally incidence, from the cancer screened for. Until recently, cancer screening has been offered to all persons in pre-defined sex- and age-groups. The exception is lung screening which is targeted to high-risk individuals. Evidence for effect of screening on cancer-specific mortality is available for cancer of the cervix, breast, color

Risk factors for frequent unplanned hospital visits in older multimorbid patients after an emergency department visit : a retrospective cohort study

BACKGROUND: Hospital readmissions are common among older multimorbid patients, and hospitalisation is associated with functional decline and reduced quality of life. Identifying patient characteristics and risk factors for repeated hospital visits following an emergency department (ED) encounter is important for guiding targeted interventions to prevent future revisits.AIM: To characterise multimo

Urban flood mapping using HEC-RAS: A case study of the Lubigi catchment in Kampala, Uganda

Urban flooding poses severe risks to lives, property, and infrastructure, particularly in rapidly urbanizing cities like Kampala, Uganda. This study focuses on the Lubigi catchment, one of Kampala's largest drainage basins, which experiences frequent pluvial flooding intensified by urban encroachment, poor drainage infrastructure, and wetland degradation. To assess flood risks, a 1D and a 2D m

Sustainable urban freight transition governance in small and medium-sized cities

This study examines how small and medium-sized, logistically prominent cities with climate ambitions govern their urban freight systems toward sustainability. It provides a framework for analyzing cities' governance from a socio-technical transition perspective and explores the interrelations between governance activity design and city administrations' capabilities to manage system development. Co

Clinical forensic examinations and prosecution in Danish child physical abuse cases

BackgroundDespite the central role of forensic medical examinations in child physical abuse cases, evidence on how their findings impact prosecution is scarce.ObjectiveWe studied the association between the dependent variable, filing of formal charges, and independent variables related to the child, suspect, and case characteristics, the acts of violence, and forensic findings, such as cutaneous l

Comorbidities in People With Intellectual Disability With and Without Schizophrenia and Schizophrenia Without Intellectual Disability : A Swedish Register Study (IDcare)

BACKGROUND: Intellectual disability (ID) and schizophrenia are known to separately carry a high risk of comorbidity of mental health and physical conditions. However, the prevalence and risk of comorbidities among people diagnosed with concurrent ID and schizophrenia have to date not been studied.METHODS: From a cohort including all people in Skåne, Sweden, the following three groups were establis

Decongestants and antihistamines for acute otitis media in children

RATIONALE: Acute otitis media (AOM) is one of the most common bacterial infections in children worldwide, and the most common reason for prescribing antibiotics. Although serious complications (e.g. mastoiditis or meningitis) are rare, the infection causes acute pain and can lead to hearing impairment. Since AOM often resolves spontaneously, current treatment guidelines recommend an approach of wa
