Parsing human rights, promoting health equity: Reflections on Colombia's response to Venezuelan migration

Over the last 7 years, a multidimensional crisis in Venezuela has resulted in massive emigration. Over 7 million have fled the country, with more than 2.4 million seeking to settle in Colombia. Of these, as of 2021, more than 1 million were undocumented, but the situation has started to change with the implementation of an ambitious migrant regularisation scheme. Regularisation promises access to

Arthroscopic partial meniscectomy vs non-surgical or sham treatment in patients with MRI-confirmed degenerative meniscus tears : a systematic review and meta-analysis with individual participant data from 605 randomised patients

Objective: To identify subgroups of patients with magnetic resonance imaging (MRI)-confirmed degenerative meniscus tears who may benefit from arthroscopic partial meniscectomy (APM) in comparison with non-surgical or sham treatment. Methods: Individual participant data (IPD) from four RCTs were pooled (605 patients, mean age: 55 (SD: 7.5), 52.4% female) as to investigate the effectiveness of APM i

Impact of Temperature-Induced Oxide Defects on HfxZr1−xO2 Ferroelectric Tunnel Junction Memristor Performance

In this work, we evaluate the importance of the postmetallization annealing (PMA) temperature on the performance of HfxZr1−xO2-based ferroelectric tunnel junctions (FTJs). Our results indicate a significant difference in tunneling electroresistance (TER) ratio and endurance, depending on the PMA temperature despite negligible variations in remanent polarization. We conclude that the minimization o

Cryogenic Characteristics of InGaAs MOSFET

We present an investigation of the temperature dependence of the current characteristic of a long-channel InGaAs quantum well MOSFET. A model is developed, which includes the effects of band tail states, electron concentration-dependent mobility, and interface trap density to accurately explain the measured data over all modes of operation. The increased effect of remote impurity scattering i

Structure of the distal lung studied with inhaled nanoparticles

Techniques able to detect impairments in the distal human lung are lacking. Since inhaled nanoparticles are predominantly deposited in the acini, their deposition can be used to derive structural properties of the region. Intheory, structural enlargements in the distal lung imply that less inhaled nanoparticles deposit there. This rationale is the basis of the airspace dimension assessment (AiDA)

Increased Physiological GDNF Levels Have No Effect on Dopamine Neuron Protection and Restoration in a Proteasome Inhibition Mouse Model of Parkinson’s Disease

Parkinson’s disease (PD) is a progressive neurodegenerative disease that comprises a range of motor and nonmotor symptoms. Glial cell line-derived neurotrophic factor (GDNF) promotes the survival of dopamine neurons in vitro and in vivo, and intracranial delivery of GDNF has been tested in six clinical trials for treating PD. However, clinical trials with ectopic GDNF have yielded variable results

Road to Total Knee Replacement: Utilization of Knee Surgeries Up to Ten Years Before Total Knee Replacement in England and Sweden

OBJECTIVE: To compare the prevalence and timing of knee surgery (including meniscal, ligamentous, synovial, and osteotomy) in the 10 years prior to primary total knee replacement (TKR) between England and Sweden.METHODS: This was a population-based, case-control study within England and southern Sweden using electronic health care databases. Patients underwent primary TKR between 2015 and 2019. Ri

Disaggregation of gold nanoparticles by Daphnia magna

The use of manufactured nanomaterials is rapidly increasing, while our understanding of the consequences of releasing these materials into the environment is still limited and many questions remain, for example, how do nanoparticles affect living organisms in the wild? How do organisms adapt and protect themselves from exposure to foreign materials? How does the environment affect the performance

Psychometric evaluation of the Texas revised inventory of grief in a sample of bereaved family caregivers

The Texas Revised Inventory of Grief (TRIG) was developed to measure the intensity of grief after the death of a close person. It consists of two scales: TRIG I (past behaviors) and TRIG II (present feelings). Because of inconsistencies in previous validations, the instrument needs to be further validated, hence the aim of this study was to evaluate the psychometric properties of the TRIG in a sam

Death of a Genre? : The Aesopic Fable and the Emergence of Modernity

Taking as its starting point the scholarly discussion about the possible death of the Aesopic fable towards the end of the eighteenth century, this article proposes a broadening of perspective, arguing for a thorough examination of the impact of modernity on some of the basic contexts and conditions of the genre. Four contextual factors are, subsequently, placed under scrutiny: the ethics of virtu

Determinants of penetrance and variable expressivity in monogenic metabolic conditions across 77,184 exomes

Hundreds of thousands of genetic variants have been reported to cause severe monogenic diseases, but the probability that a variant carrier develops the disease (termed penetrance) is unknown for virtually all of them. Additionally, the clinical utility of common polygenetic variation remains uncertain. Using exome sequencing from 77,184 adult individuals (38,618 multi-ancestral individuals from a

Higher Self-Esteem Associated With Less Symptoms of Anxiety and Depression Among Young Adults After the Loss of a Parent to Cancer—A Longitudinal Study

Objective: The purpose of the study was to examine associations between self-esteem and symptoms of anxiety and depression among young adults who lost a parent to cancer. Methods: Older adolescents and young adults, aged 16 to 28 years, who had lost their parent to cancer and had accepted an invitation to join a support group, completed a questionnaire 5 to 8 months after the loss and a similar qu

Functional Assessment of Direct Reprogrammed Neurons In Vitro and In Vivo

Direct reprogramming is an emerging research field where you can generate neurons from a somatic cell, such as a skin or glial cell by overexpressing neurogenic transcription factors. This technique allows fast generation of subtype-specific and functional neurons from both human and mouse cells. Despite the fact that neurons have been successfully generated both in vitro and in vivo, a more exten

The triglyceride-glucose index as a measure of insulin resistance and risk of obesity-related cancers

Background: The role of insulin resistance as a mediator in the association of body mass index (BMI) with site-specific cancer risk has, to our knowledge, never been systematically quantified. Methods: Altogether 510 471 individuals from six European cohorts, with a mean age of 43.1 years, were included. We used the triglyceride glucose product (TyG index) as a surrogate measure for insulin resist

A Comparison of tumor demarcation potential for various hematoporphyrin derivatives and phtalocyanine using laser-induced fluorescence

Laser-induced fluorescence data for rats injected with the different tumor-marking drugs, dihematoporphyrin ether, poly hematoporphyrin esters, hematoporphyrin and phtalocyanine, are presented. Studies were performed at two different excitation wavelengths. Comparisons between the different drugs are made with regard to fluorescence intensity and tumor demarcation capability. Further, the origin o

Acoustic cell patterning in hydrogel for three-dimensional cell network formation

In the field of engineered organ and drug development, three-dimensional network-structured tissue has been a long-sought goal. This paper presents a direct hydrogel extrusion process exposed to an ultrasound standing wave that aligns fibroblast cells to form a network structure. The frequency-shifted (2 MHz to 4 MHz) ultrasound actuation of a 400-micrometer square-shaped glass capillary that was

Changes in Intestinal Permeability Ex Vivo and Immune Cell Activation by Three Commonly Used Emulsifiers

Food additives such as emulsifiers are used in increasing quantities in the food industry. The aim of this study was to compare three different emulsifiers (polysorbate 80 (P80), carboxymethyl cellulose (CMC), and β-lactoglobulin (β-lac) with regards to their effect on the stimulation of immune cells and intestinal permeability. The immune stimulatory effects were studied in the myeloid cell line

No gender-related bias in COPD diagnosis and treatment in Sweden : a randomised, controlled, case-based trial
