Background: Differences in the expression of regulatory T cells (Tregs) have been suggested to explain why some smokers develop COPD and some do not. Upregulation of Tregs in response to smoking would restrain airway inflammation and thus the development of COPD; while the absense of such upregulation would over time lead to chronic inflammation and COPD. We hypothesized that—among COPD patients—t
Background: In COPD, the balance between matrix metalloproteinases (MMPs) and their natural inhibitors [tissue inhibitors of metalloproteinases (TIMPs)] is shifted towards excessive degradation, reflected in bronchoalveolar lavage (BAL) as increased MMP concentrations. Because of their critical role in lung homeostasis, MMP activity is tightly regulated, but to what extent this regulation occurs t
This study presents the results of an interlaboratory test designed to evaluate the accuracy of spectral induced polarization (SIP) measurements using controlled electrical test networks. The study, conducted in Germany since 2006, involved 12 research institutes, six different impedance measurement devices and four types of electrical test networks specifically designed to evaluate phase shift err
In the past two decades there’s been an incredible development in the field of in vitro neural cultures. Thanks to the developments in embryonic stem cell technology, and the ability to produce pluripotent stem cells from adult human cells, producing human neural cultures has become much more widely accessible, and the ability to recreate physiological processes is increasing at an accelerating ra
BACKGROUND: The advent of PD-1/PD-L1 inhibitors has revolutionized lung cancer treatment, necessitating accurate PD-L1 immunohistochemical (IHC) assessment. While standardized for formalin-fixed paraffin-embedded (FFPE) histological samples, PD-L1 testing on cytology remains challenging. This review aims to address the complexities of PD-L1 IHC in cytology, focusing on validation guidelines, quali
In 2015 the Rockefeller Foundation-Lancet Commission defined planetary health as built on an ecological model that integrates the material, biological, social, and cultural aspects of public health and accepts the complexity and non-linearity of the dynamics of natural systems. The zoonotic COVID-19 pandemic hastened this awaking to the symbiotic nature of planetary health politics (PHP), with the
Några av världens allra främsta universitet har blivit måltavla i Trumpadministrationens kamp mot ”galna marxister” som presidenten kallar ledningen där. Vad blir följderna? Ginna Lindberg, SR:s USA-korrespondent har följt frågan och ger en resumé och bild av stämningen. Hon har själv fått frågor av akademiker om hur de ska göra för att flytta till Europa med sin forskning. Historikern Johan Östli
The roundtable brings together three of the authors and a former journal editor, from the recent JCMS 20th Anniversary SYmposium to discuss: What does the Arrival of Planetary Politics tell us about normative power and the European Union?Ian Manners provides a reflection and prospective intervention on the development of normative power and thinking through the EU in the rest of the century.

OBJECTIVE: To investigate associations between meniscal tear, bone marrow lesions (BMLs), and post-injury knee loading, with cartilage T2 relaxation times on knee magnetic resonance imaging (MRI) in the subacute phase following acute anterior cruciate ligament (ACL) injury.DESIGN: We studied both knees of 128 patients with ACL injury. The presence of meniscal tears and BMLs were determined on suba
