Manufacturing of Human Tissues as off-the-Shelf Grafts Programmed to Induce Regeneration

Design criteria for tissue-engineered materials in regenerative medicine include robust biological effectiveness, off-the-shelf availability, and scalable manufacturing under standardized conditions. For bone repair, existing strategies rely on primary autologous cells, associated with unpredictable performance, limited availability and complex logistic. Here, a conceptual shift based on the manuf

Impact of concomitant complex cardiac anatomy in nonsyndromic patients with complete atrioventricular septal defect

Objective: We studied a cohort of patients with nonsyndromic complete atrioventricular septal defect with and without concomitant complex cardiac anatomy and compared the outcomes after surgical repair. Methods: Between 1993 and 2018, 62 nonsyndromic patients underwent complete atrioventricular septal defect repair. Sixteen patients (26%) had complex complete atrioventricular septal defect with va

Opportunities and challenges of high‐pressure fast pyrolysis of biomass : A review

Most pyrolysis reactors require small sizes of biomass particles to achieve high‐quality products. Moreover, understanding the usefulness of high‐pressure systems in pyrolysis is important, given the operational challenges they exhibit specific to various biomass materials. To actualize these aspects, the authors first checked previous reviews involving pyrolysis on different biomass and different

Efficacy of mepolizumab in usual clinical practice and characteristics of responders : Mepolizumab in usual clinical practice

Background: Severe eosinophilic asthma is a high-burden disease. Mepolizumab has been effective in several randomized clinical trials. However, such success might not be applicable to patients treated in usual clinical practice. The objectives of this article are to evaluate the efficacy of mepolizumab in severe uncontrolled eosinophilic asthma under usual clinical practice, and to determine chara

Conservation Organizations Need to Consider Adaptive Capacity : Why Local Input Matters

Conservation organizations are increasingly applying adaptive capacity assessments in response to escalating climate change impacts. These assessments are essential to identify climate risks to ecosystems, prioritize management interventions, maximize the effectiveness of conservation actions, and ensure conservation resources are allocated appropriately. Despite an extensive literature on the top

Conclusions

We have learnt several lessons from the Nordic countries. The management of natural resources can explain a notable part of their success, but it would be naive to extract from the chapters in this book a recipe laying out a path to success for countries with abundant natural resources.

Climate change, environmental degradation and migration

Climate change will have a progressively increasing impact on environmental degradation and environmentally dependent socio-economic systems with potential to cause substantial population displacement. The key concerns in Less Developed Countries (LDCs) will include serious threats to food security and health, considerable economic decline, inundation of coastal areas, and degradation of land and

Neurofeedback Rehabilitation Reduces Anxiety in Methamphetamine Abusers

Addictive disorders are characterized by cognitive, behavioral, and neurological impairments caused by dysregulations of brain structure that can extend well beyond early withdrawal in the months and years of recovery. The present study aimed to examine the efficacy of neurofeedback rehabilitation on anxiety in methamphetamine abusers. The sample consisted of 14 male methamphetamine drug addicts w

Women with a history of recurrent pregnancy loss are a high-risk population for adverse obstetrical outcome : A retrospective cohort study

Recurrent pregnancy loss (RPL), defined as three or more consecutive miscarriages, is hypothesized to share some of the same pathogenic factors as placenta-associated disorders. It has been hypothesized that a defect implantation causes pregnancy loss, while a partially impaired implantation may lead to late pregnancy complications. The aim of this retrospective register-based cohort study was to

Terror remembered, terror forgotten : Stalinist, Nazi, and nationalist atrocities in Ukrainian 'national memory

In the 1930s and 1940s, Ukraine experienced political violence on an unprecedented scale. Political violence by the Soviet government and the German occupation authorities resulted in the death of millions, through starvation, deportations, and massacres, and left wounds which still have not fully healed. Independently of the Soviets and Nazis, mass political violence was carried out also by the O

Mobility and muscle strength trajectories in old age : the beneficial effect of Mediterranean diet in combination with physical activity and social support

Introduction: Decline in physical function varies substantially across older individuals due to several extrinsic modifiable factors such as dietary patterns, physical activity and social support. We aimed to determine the association of these factors and their interaction with mobility and muscle strength decline. Methods: We analyzed data from 1686 functionally healthy individuals aged 60 + from

The impact of age and 24-h blood pressure on arterial health in acute ischemic stroke patients : The Norwegian stroke in the young study

The impact of age and 24-h ambulatory blood pressure (ABPM) on arterial stiffness and carotid intima-media thickness (cIMT) in ischemic stroke patients younger than 60 years of age is poorly explored. A total of 385 acute ischemic stroke patients (aged 49.6±9.7 years, 68% men) were prospectively included and grouped in younger (15–44 years, n = 93) and middle-aged (45–60 years, n = 292). Arterial

Airborne Gold Nanoparticle Detection Using Photoluminescence Excited with a Continuous Wave Laser

We report the observation of photoluminescence emission from airborne gold, silver, and copper nanoparticles. A continuous wave 532 nm laser was employed for excitation. Photoluminescence from gold nanoparticles carried in a nitrogen gas flow was both spectrally resolved and directly imaged in situ using an intensified charge-coupled device camera. The simultaneously detected Raman signal from the

Correlation-Driven Transient Hole Dynamics Resolved in Space and Time in the Isopropanol Molecule

The possibility of suddenly ionized molecules undergoing extremely fast electron hole (or hole) dynamics prior to significant structural change was first recognized more than 20 years ago and termed charge migration. The accurate probing of ultrafast electron hole dynamics requires measurements that have both sufficient temporal resolution and can detect the localization of a specific hole within
