Do agri-food market incentives improve food security and nutrition indicators? a microsimulation evaluation for Kenya.

Unlabelled: The sustainable development goal #2 aims at ending hunger and malnutrition by 2030. Given the numbers of food insecure and malnourished people on the rise, the heterogeneity of nutritional statuses and needs, and the even worse context of COVID-19 pandemic, this has become an urgent challenge for food-related policies. This paper provides a comprehensive microsimulation approach to evaluate economic policies on food access, sufficiency (energy) and adequacy (protein, fat, carbohydrate) at household level.

Raw cooked food matching: Nutrient intake using the 2015/16 Kenya Integrated Household Budget Survey.

In many countries, statistics from household consumption and expenditure surveys are increasingly being used to inform policies and programs. In household surveys, foods are typically reported as they are acquired (the majority are raw). However, the micronutrient content of some foods diminishes during processing and cooking.

Food security and welfare changes under COVID-19 in Sub-Saharan Africa: Impacts and responses in Kenya.

The COVID-19 pandemic has affected all Sub-Saharan economies through a multitude of impact channels. The study determines the medium-term macroeconomic outcomes of the pandemic on the Kenyan economy and links the results with a detailed food security and nutrition microsimulation module. It thus evaluates the effectiveness of the adopted government measures to reduce the negative outcomes on food security and to enable economic recovery at aggregate, sectoral and household levels.

Endogenous pleiotrophin and midkine regulate LPS-induced glial responses.

Pleiotrophin (PTN) and Midkine (MK) are two growth factors that modulate neuroinflammation. PTN overexpression in the brain prevents LPS-induced astrocytosis in mice but potentiates microglial activation. The modest astrocytic response caused by a low dose of LPS (0.

Short-term vitamin E treatment impairs reactive oxygen species signaling required for adipose tissue expansion, resulting in fatty liver and insulin resistance in obese mice.

Objectives: The use of antioxidant therapy in the treatment of oxidative stress-related diseases such as cardiovascular disease, diabetes or obesity remains controversial. Our aim is to demonstrate that antioxidant supplementation may promote negative effects if used before the establishment of oxidative stress due to a reduced ROS generation under physiological levels, in a mice model of obesity.

Methods: C57BL/6J mice were fed with a high-fat diet for 14 weeks, with (OE group) or without (O group) vitamin E supplementation.

Vascular Dysfunction in Mother and Offspring During Preeclampsia: Contributions from Latin-American Countries.

Pregnancy is a physiologically stressful condition that generates a series of functional adaptations by the cardiovascular system. The impact of pregnancy on this system persists from conception beyond birth. Recent evidence suggests that vascular changes associated with pregnancy complications, such as preeclampsia, affect the function of the maternal and offspring vascular systems, after delivery and into adult life.

Pleiotrophin regulates microglia-mediated neuroinflammation.

Background: Pleiotrophin (PTN) is a cytokine found highly upregulated in the brain in different disorders characterized by overt neuroinflammation such as neurodegenerative diseases, drug addiction, traumatic injury, and ischemia. In the present work, we have explored whether PTN modulates neuroinflammation and if Toll-like receptor 4 (TLR4), crucial in the initiation of an immune response, is involved.

Methods: In immunohistochemistry assays, we studied lipopolysaccharide (LPS, 7.

Midkine Is a Novel Regulator of Amphetamine-Induced Striatal Gliosis and Cognitive Impairment: Evidence for a Stimulus-Dependent Regulation of Neuroinflammation by Midkine.

Midkine (MK) is a cytokine that modulates amphetamine-induced striatal astrogliosis, suggesting a possible role of MK in neuroinflammation induced by amphetamine. To test this hypothesis, we studied astrogliosis and microglial response induced by amphetamine (10 mg/kg i.p.

Peroxisome proliferator activated receptor gamma 2 modulates late pregnancy homeostatic metabolic adaptations.

Pregnancy requires the adaptation of maternal energy metabolism including expansion and functional modifications of adipose tissue. Insulin resistance (IR), predominantly during late gestation, is a physiological metabolic adaptation that serves to support the metabolic demands of fetal growth. The molecular mechanisms underlying these adaptations are not fully understood and may contribute to gestational diabetes mellitus.

Genetic inactivation of midkine modulates behavioural responses to ethanol possibly by enhancing GABA(A) receptor sensitivity to GABA(A) acting drugs.

Midkine (MK) is a cytokine with important functions in dopaminergic neurons that is found upregulated in the prefrontal cortex of alcoholics. We have studied the behavioural effects of ethanol in MK genetically deficient (MK-/-) and wild type (MK+/+) mice. A low dose of ethanol (1.

Pleiotrophin differentially regulates the rewarding and sedative effects of ethanol.

Pleiotrophin (PTN) is a cytokine with important roles in dopaminergic neurons. We found that an acute ethanol (2.0 g/kg, i.

Leptin drives fat distribution during diet-induced obesity in mice.

Objective: Desensitization of leptin receptors is a process that specifically occurs in some tissues. We have hypothesized that during the development of obesity tissue lipids would increase gradually in particular organs depending on leptin responsiveness. Our aim was to establish a relationship between leptin resistance and lipid deposition by using a model of diet-induced obesity (DIO) and we have characterized, in mice undergoing a dietary treatment with a high-fat (HF) diet, the evolution of lipid content and leptin responsiveness in white adipose tissue and liver.

Enhanced utilization of glycerol for glyceride synthesis in isolated adipocytes from early pregnant rats.

Adipose tissue normally has low glycerol kinase activity, but its expression is enhanced under conditions of augmented insulin sensitivity and/or obesity. Since these conditions occur during early pregnancy, the comparative utilization of glucose or glycerol by isolated adipocytes from rats at 0, 7, 14, or 20 days of pregnancy was studied. Incubations were carried out in the presence of [U(14)C]-glucose or -glycerol in medium supplemented or not with 5 mM glucose and 100 nM insulin.

[Diagnostic performance of anti-cyclic citrullinated antibodies and IgM rheumatoid factor in rheumatoid arthritis].

Unlabelled: The presence of IgM class rheumatoid factor RF-M in the serum is one of the ACR criteria for the classification of rheumatoid arthritis RA .

Objectives: To compare the sensitivity and specificity of two diagnostic markers for RA in Portuguese patients the 2nd generation anti-cyclic citrullinated peptide antibodies anti-CCP2 and the RF-M.

Methods: Serum samples from 56 patients with established RA 44 women and 12 men mean disease duration 9 5 -8 5 years were evaluated for the presence of anti-CCP2 and RF-M.

Morphine differentially regulates hsp90beta expression in the nucleus accumbens of Lewis and Fischer 344 rats.

We have comparatively studied hsp90beta gene and protein expression in the nucleus accumbens of Lewis and Fischer 344 (F344) rats, two inbred strains that exhibit prominent behavioural differences in drug-seeking behaviours. Phenotypical studies confirmed that Lewis rats developed a higher preference for morphine-paired environments after conditioning. RT-PCR assays did not reveal strain-related differences in hsp90beta gene expression in basal conditions; however, acute morphine treatment provoked an increase of hsp90beta mRNA 2h after injection only in the case of Lewis rats.

Obesity is independently associated with impaired quality of life in patients with rheumatoid arthritis.

Obesity is a modifiable major cause of morbidity and mortality in the general population, but little is known about the association of obesity and quality of life in patients with rheumatoid arthritis (RA). Thus, we set out a study to test the hypothesis that obesity is independently associated with lower quality of life in patients with RA. Three hundred and fifty nine patients with RA underwent an interview, physical exam, and all clinical charts were reviewed.

[Assessement of an automated homogeneous liposome-based immunoassay system for total complement activity].

The Immunology department of Garcia de Orta Hospital, has evaluated a new automated homogeneous liposome-based immunoassay (L.I.A.
