How Norwayâs Sovereign Wealth Fund Affect the Excluded Companiesâ Stock Price
This thesis examines the effect Norwayâs Government Pension Fund Global (GPFG) has on the companies it excludes from the portfolio. The data sample consists of 25 companies excluded based on environmental damage and unacceptable greenhouse gas (GHG) emissions. An event study has been conducted to examine whether the exclusion from the fund has a negative impact on the companiesâ stock prices. This makes it possible to examine the abnormal returns, and whether they are affected by the exclusion. The main findings and conclusion are that the exclusions do not negatively influence the excluded firms. The influence of exclusions does not result in statistically significant negative abnormal returns, and thus we fail to reject the null hypothesis. These findings are inconsistent with the majority of earlier studies, which found that the exclusion had a statistically significant negative impact on the excluded companies. This may be because of the differences in the data selection, and information leakage, or it might be explained by the fact that there are always willing buyers. One explanation may also be that investors do not regard sustainability as important and essential for their investments
Impaired transmission in the corticospinal tract and gait disability in spinal cord injured persons
Rehabilitation following spinal cord injury is likely to depend on recovery of corticospinal systems. Here we investigate whether transmission in the corticospinal tract may explain foot drop (inability to dorsiflex ankle) in persons with spinal cord lesion. The study was performed in 24 persons with incomplete spinal cord lesion (C1 to L1) and 15 healthy controls. Coherence in the 10- to 20-Hz frequency band between paired tibialis anterior muscle (TA) electromyographic recordings obtained in the swing phase of walking, which was taken as a measure of motor unit synchronization. It was significantly correlated with the degree of foot drop, as measured by toe elevation and ankle angle excursion in the first part of swing. Transcranial magnetic stimulation was used to elicit motor-evoked potentials (MEPs) in the TA. The amplitude of the MEPs at rest and their latency during contraction were correlated to the degree of foot drop. Spinal cord injured participants who exhibited a large foot drop had little or no MEP at rest in the TA muscle and had little or no coherence in the same muscle during walking. Gait speed was correlated to foot drop, and was the lowest in participants with no MEP at rest. The data confirm that transmission in the corticospinal tract is of importance for lifting the foot during the swing phase of human gait

Long COVID symptoms and duration in SARS-CoV-2 positive children - a nationwide cohort study
Most children have a mild course of acute COVID-19. Only few mainly non-controlled studies with small sample size have evaluated long-term recovery from SARS-CoV-2 infection in children. The aim of this study was to evaluate symptoms and duration of âlong COVIDâ in children. A nationwide cohort study of 37,522 children aged 0â17 years with RT-PCR verified SARS-CoV-2 infection (response rate 44.9%) and a control group of 78,037 children (response rate 21.3%). An electronic questionnaire was sent to all children from March 24th until May 9th, 2021. Symptoms lastingâ>â4 weeks were common among both SARS-CoV-2 children and controls. However, SARS-CoV-2 children aged 6â17 years reported symptoms more frequently than the control group (percent difference 0.8%). The most reported symptoms among pre-school children were fatigue Risk Difference (RD) 0.05 (CI 0.04â0.06), loss of smell RD 0.01 (CI 0.01â0.01), loss of taste RD 0.01 (CI 0.01â0.02) and muscle weakness RD 0.01 (CI 0.00â0.01). Among school children the most significant symptoms were loss of smell RD 0.12 (CI 0.12â0.13), loss of taste RD 0.10 (CI 0.09â0.10), fatigue RD 0.05 (CI 0.05â0.06), respiratory problems RD 0.03 (CI 0.03â0.04), dizziness RD 0.02 (CI 0.02â0.03), muscle weakness RD 0.02 (CI 0.01â0.02) and chest pain RD 0.01 (CI 0.01â0.01). Children in the control group experienced significantly more concentration difficulties, headache, muscle and joint pain, cough, nausea, diarrhea and fever than SARS-CoV-2 infected. In most children âlong COVIDâ symptoms resolved within 1â5 months. Conclusions: Long COVID in children is rare and mainly of short duration.

Weight loss practices in amateur wrestlers and its relationship to disordered eating
The premise behind many athletic programs is to encourage wellness, a state of well being in both physical and emotional aspects. This research paper reviews how wrestling and other athletic programs where weight plays a significant role, may affect eating and other weight-related habits. It addresses whether weight loss practices in wrestling play a role in disordered eating patterns of its participants
Kinetics of the appearance of cereal alkylresorcinols in pig plasma
Alkylresorcinols (AR) are phenolic lipids found in high amounts in wholegrain wheat and rye. They may be important as bioactive components
and/or biomarkers of wholegrain wheat and rye intake. AR absorption was studied with pigs during a habitual diet and after a single meal of ARrich
diet. In study 1, four pigs were fed wholegrain rye (RD) and white wheat bread (WD) for 1 week in a cross-over design. Arterial and venous
AR concentrations were determined over 540 min after feeding on days 5 and 7. In study 2, four pigs were fed a synthetic, starch-based diet for 5 d,
and arterial and venous AR concentrations were determined over 960 min after feeding a single meal of RD. In study 1, plasma AR concentrations
after consuming RD peaked at 120 min, remained elevated between 120 and 420 min, and were re-elevated on refeeding at 480 min. In study 2, AR
appeared in the plasma after 60 min, peaked at 180â240 min, and remained elevated after 960 min. The apparent elimination half-life was 3¡93 h,
and the maximum plasma concentration was 666 (SEM 35) nmol/l. Arterial and venous plasma AR concentrations were similar, suggesting that AR
are absorbed via the lymphatic system. AR concentrations in pig plasma increase rapidly after a meal containing AR, and persist in plasma for at
least 5 d, indicating that AR may be a useful biomarker of wholegrain wheat and rye intake.The present study was supported by the Nordic Industrial Fund; the Danish Agricultural and Veterinary Research Council; Cerealia AB, Sweden; Wasabro¨d AB, Sweden; Vaasan & Vaasan, Finland; Fazer Oululainen, Finland.
