Optical properties of cadmium sulfide nanoparticles on the surface of polytetrafluoroethylene nanogranules

The spectral characteristics in the visible range of synthesized nanocomposites based on cadmium sulfide and ultradispersed polytetrafluoroethylene are investigated experimentally. Local perturbations are found in the long-wavelength regions of the reflection and absorption spectra, which are related to the optical transitions between the critical points of the valence and conduction bands of the

Non-reproductive effects of follicle-stimulating hormone in young men

Objective: Follicle-stimulating hormone (FSH) receptor expression has been reported in many extra-gonadal tissues, raising the question of non-reproductive effects of FSH. Because of increasing usage of FSH in treatment of male infertility, deeper knowledge of possible harmful off-target effects of FSH is warranted. Methods: In total, 33 healthy young men (mean age 30 years) were included in the s

Gender-based violence against Women with Disabilities in Uganda - A qualitative study about how local organizations are working with the issue

Gender-based violence (GBV) is both a human right violation, a threat to develop-ment and a global health issue. Women with disabilities (WWD) are a group more exposed to GBV. However, research has been scarce about WWD and GBV, espe-cially in the Global South. This thesis studies how local organizations are working on the issue of GBV targeting WWD in Uganda. The theoretical framework em-ployed i

Sporadic accelerations during labor strongly indicate normal pH, whereas periodic accelerations do not: a case-control study

PurposeTo determine the association between the occurrence of sporadic and periodic fetal heart rate accelerations during labor and acidemia at birth.Materials and methodsThis is a case–control study of fetal heart rate patterns from 364 neonates with acidemia at birth (cord blood pH ResultsDuring the first stage, ≥2 sporadic accelerations were present in 16% of cases and 78% of controls; OR for a

Clinical significance of stem cell biomarkers epcam, lgr5 and lgr4 mrna levels in lymph nodes of colon cancer patients

The significance of cancer stem cells (CSCs) in initiation and progression of colon cancer (CC) has been established. In this study, we investigated the utility of measuring mRNA expression levels of CSC markers EpCAM, LGR5 and LGR4 for predicting survival outcome in surgically treated CC patients. Expression levels were determined in 5 CC cell lines, 66 primary CC tumors and 382 regional lymph no

Association of Daily Eating Duration and Day-To-Day Variability in the Timing of Eating With Fatal Cancer Risk in Older Men

Meal timing has significant effects on health. However, whether meal timing is associated with the risk of developing and dying of cancer is not well-researched in humans. In the present study, we used data from 941 community-dwelling men aged 71 years who participated in the Uppsala Longitudinal Study of Adult Men to examine the association of meal timing with cancer morbidity and fatal cancer. T

The performance of plasma amyloid beta measurements in identifying amyloid plaques in Alzheimer's disease : a literature review

The extracellular buildup of amyloid beta (Aβ) plaques in the brain is a hallmark of Alzheimer's disease (AD). Detection of Aβ pathology is essential for AD diagnosis and for identifying and recruiting research participants for clinical trials evaluating disease-modifying therapies. Currently, AD diagnoses are usually made by clinical assessments, although detection of AD pathology with positron e

Similar, yet different! Comparing Ugandan secondary cities' food system and nutritional transformations to findings from African primary cities

This research focuses on the food, farming and health experiences of two secondary cities of Uganda (Mbale and Mbarara), comparing findings with studies of primary African cities. We draw from survey data, focus groups with healthcare professionals, and in-depth interviews with varied residents. A feminist geographic perspective explored intersections of food, farming and health with varied aspect

Changing societal challenges and priorities call for new ways of managing agricultural land and for new forms of land ownership. The Danish pilot programme for multifunctional land consolidation (MUFJO) is seen as a frontrunner for a larger land reform. The programme ensures collective planning and long-term solutions, but cannot alone ensure the goals for re-wetting agricultural lands as stipulat

Ephemeral Cities : Radio Show for Elements program on cola bora dio

I was invited to make a program for cola bora dio about my work with this project by sound and radio artist Kate Donovan, on her regular program Elements, in 2019. This is a recording of the live broadcast of that program. Cola bora dio is a low-power FM and online broadcast based in Berlin, with re-broadcasts and collaborations with other small-scale independent radio stations and artists worldwi

Predicting the Solubility of Inorganic Ion Pairs in Water

Polyoxometalates (POMs), ranging in size from 1 to 10’s of nanometers, resemble building blocks of inorganic materials. Elucidating their complex solubility behavior with alkali-counterions can inform natural and synthetic aqueous processes. In the study of POMs ([Nb24O72H9]15−, Nb24) we discovered an unusual solubility trend (termed anomalous solubility) of alkali-POMs, in which Nb24 is most solu

Examining the orbital decay targets KELT-9 b, KELT-16 b, and WASP-4 b, and the transit-timing variations of HD 97658 b,

Context. Tidal orbital decay is suspected to occur for hot Jupiters in particular, with the only observationally confirmed case of this being WASP-12 b. By examining this effect, information on the properties of the host star can be obtained using the so-called stellar modified tidal quality factor Q′∗, which describes the efficiency with which the kinetic energy of the planet is dissipated within

Brain connectomics : time for a molecular imaging perspective?

In the past two decades brain connectomics has evolved into a major concept in neuroscience. However, the current perspective on brain connectivity and how it underpins brain function relies mainly on the hemodynamic signal of functional magnetic resonance imaging (MRI). Molecular imaging provides unique information inaccessible to MRI-based and electrophysiological techniques. Thus, positron emis

FOXO3A-short is a novel regulator of non-oxidative glucose metabolism associated with human longevity

Intronic single-nucleotide polymorphisms (SNPs) in FOXO3A are associated with human longevity. Currently, it is unclear how these SNPs alter FOXO3A functionality and human physiology, thereby influencing lifespan. Here, we identify a primate-specific FOXO3A transcriptional isoform, FOXO3A-Short (FOXO3A-S), encoding a major longevity-associated SNP, rs9400239 (C or T), within its 5′ untranslated re

E3 Ubiquitin Ligase Midline 1 Regulates Endothelial Cell ICAM-1 Expression and Neutrophil Adhesion in Abdominal Sepsis

Septic lung damage is associated with endothelial cell and neutrophil activation. This study examines the role of the E3 ubiquitin ligase midline 1 (Mid1) in abdominal sepsis. Mid1 expression was increased in endothelial cells derived from post-capillary venules in septic mice and TNF-α challenge increased Mid1 levels in endothelial cells in vitro. The siRNA-mediated knockdown of Mid1 decreased TN

A multi-scale in silico mouse model for diet-induced insulin resistance

Insulin resistance causes compensatory insulin production, which in humans can eventually progress to β-cell failure and type 2 diabetes (T2D). This disease progression involves multi-scale processes, ranging from intracellular signaling to organ and whole-body level regulations, on timescales from minutes to years. T2D progression is commonly studied using overfed and genetically modified rodents

Virtual participatory mapping of nature-based solutions in the Grande de Tárcoles River basin, Costa Rica : Connecting diverse knowledge systems in a context of physical immobility

Co-design processes are of key importance in planning and implementing Nature-based Solutions (NBS), but require boundary management between diverse holders of local, practical and scientific knowledge. Participatory and mapbased planning tools, such as Geodesign workshops, can facilitate such boundary management through mobilising knowledge holders, and translating and negotiating between differe
