Galactose in dairy products

Milk and milk consumption has been subject of discussion for a long time, and is still a hot topic. Recently, as study was published that observed a correlation between milk intake and increased risk of fractures and mortality. The authors proposed the milk?s content of D-galactose as the possible mechanism, since D-galactose is used indicated ageing in animal models. Therefore, this study aims to develop a method to determine the amount of galactose, glucose and lactose in milk and fermented milk and apply it on to dairy products on the Swedish market.

Side effects of biological control agents in agriculture : does the bacteria Bacillus amyloliquefaciens affect the earthworm Aporrectodea longa?

Pathogenic microorganisms pose a big threat towards food production. Meanwhile, negative impacts on humans and environment are seen by the use of pesticides. Biological control agents are an alternative to the use of chemical pesticides, and plant-growth promoting rhizobacteria, such as Bacillus amyloliquefaciens has been shown to have good properties as biocontrol agents. Before these bacteria can be used commercially their impact on other soil organisms has to be evaluated. This thesis looks into what biocontrol bacteria are and how they might affect earthworms.

Motivation for eating roughage in sows : as an indiction of hunger

Today?s feeding methods can determine the domestic pig?s abilities to fulfill basic behavioral needs, such as foraging, and the way in which pigs are feed is an important aspect. Feed does not only provide the energy and nutrients critical for survival, but feeding is also associated with a number of other factors contributing to well-being and reproduction. Today the feed for gestated sows is often composed by high energy and low dietary fiber grain products such as wheat. Three kg of this kind of feed can often be consumed by the sow within 20 minutes.

Fåglar i urbana miljöer : kvaliteten på urbana habitat och om beståndstäthet är ett bra mått på habitatkvalitet

The urbanization of the world is increasing. How it affects bird populations have been well studied during the last decade, and comparisons between urban and non-urban habitats have been carried out. A common method for measuring habitat quality is to calculate the population density. This method is easy to use, but have been criticized during the last couple of years. In this study, data of population densities was compared with data on reproduction success.

Oönskade Döttrar - Traditionella mönster i ett modernt samhälle

Due to traditional beliefs about biological differences between the sexes, the sex ratio is abnormally uneven in northern parts of India. There is a combination of old methods like female infanticide and new technologies, which make selective abortion possible. The strong practices of dowry transform daughters to economical burdens to their parents. They face mortal danger before, at and after birth. With rapid economical progress and advanced technology, India is a country in progress.

Träningsappar som verktyg i hälsofrämjande syfte : - Användares erfarenheter och upplevelser

Physical inactivity is the fourth leading risk factor for global mortality. To prevent and change this the society need to develop good approaches and interventions to promote physical activity. The purpose of this thesis was to investigate which experience existing users have of smartphone training applications. Also to study if this can be a possible resource for health promotion. Six active users applied to participation after they had seen an ad in social media.

Sjuknärvaro i Skandinavien

Background: Research on presenteeism has been performed mainly during the last 15 years, where several consequences on health such as cardiovascular disease and mortality have been identified. Studies have shown a relation between sickness absenteeism and presenteeism, where presenteeism could lead to long-term sickness absence. Aim: The aim of the present study was to investigate work-related and personal causes of sickness presenteeism. The study also aimed to identify the overall prevalence of sickness presence in Scandinavia, including potential occupational sectors with higher prevalence. Method: The study was literature based and consisted of 15 peer-reviewed scientific articles that were found by a systematic search in PubMed and Scopus.

Mjölkkors behov av att ligga och att sova

The aim of this literature review was to investigate whether the modern dairy cow has the time she needs to lie down and to sleep and what deprivation of these behaviors could lead to. Current research seems to agree on the fact that sleep is essential but there is no uniform explanation of the function of sleep, even though there are many theories. It is known that sleep has an important impact on the immune system and that sleep is increased in case of an infection. Sleep deprivation causes many negative effects including reduced function off the immune defense, increased metabolic activity, malnutrition and increased heart rate. It has also been found that deprivation of sleep could cause increased mortality.

The Weight of Nature

There is an expression called ?grief of climate? that refers to feelings of powerlessness and heaviness related to the environmental problems of today. A feeling that every move we make has bad consequences for nature. This essay is an investigation of how art in general and jewellery art in particular can be a way of discussing and visualizing current environmental problems and the complex relationship between human and nature. I am discussing how artworks dealing with a dark and dystopian picture of the relation can be seen as the memento mori of our time.

Obstruktiv FLUTD - ett nödvändigt ont eller möjligt att förebygga?

FLUTD - Feline Lower Urinary Tract Disease ? is a complex disease and a common sight in the veterinary setting. Although FLUTD excluding urethral obstruction may be discomforting for the cat and its owner due to symptoms such as periuria, stranguria, hematuria, dysuria and pollakiuria, obstruction presents an acute and potentially lethal form of the disease as a result of uremia and disturbances in fluids, electrolytes and acid-base balances. A study of literature has been performed to investigate the causes of FLUTD with urethral obstruction and the actions available to the owner to avert them. Potential causes of obstructive and non-obstructive FLUTD have been found to include infections, uroliths, urethral plugs, neoplasia, anatomic abnormalities, trauma, neurogenic or iatrogenic causes. Most commonly a cause cannot be identified and the terms idiopathic FLUTD or feline idiopathic cystitis are used. As the mortality rate due to urethral obstruction likely is somewhere around 5.8-8.9% and FLUTD including and excluding urethral obstruction constitute great inconveniences, precautionary measures are warranted.

Felaktig alternativ splicing: Vissa mutationer i BRCA1, BRCA2, ER? och ER? är starkt förknippade med bröstcancer

Alternative splicing is a process that partly rejects the common definition of a gene ? that one gene codes for one specific protein. By variable combination of coding regions (exons) and exclusion of non-coding regions (introns), formation of several different mRNA-transcripts, and consequently several different proteins, can derive from the same gene. Alternative splicing is an important condition for the development of complex life forms, but it is also a highly sensitive process and inaccurate splicing is the cause of approximately 15 % of mutations that cause genetic diseases. This article presents four genes, BRCA1, BRCA2, ER? and ER?, and inaccurate splicing of these genes increases the risk of developing cancer, particularly breast cancer and ovarian cancer.

Insättningsålderns påverkan på kalvens hälsa i gruppbox :

In modern dairy production, the newborn calf generally is separated from its mother and put in a single pen for some time before it is introduced to group housing. Group housing is becoming more and more common because it saves the farmer a lot of valuable time. Even thought group housing has a lot of benefits it is often associated with a higher morbidity and mortality in the young calves. Therefore, knowing the optimal way to use the group pen lies in many farmers? interests and the importance of different factors such as the optimal age of introduction is important to evaluate. The aim of this study was to investigate the effect of age at introduction to group housing on the health of the calves in the group pen.

Anestesi vid kastration av spädgris :

An overwhelming majority of all male piglets are castrated without anaesthesia when they are very young. In Sweden this means that approximately one and a half million piglets are castrated every year. The reason the piglets are castrated is the strong and unpleasant smell and taste, the ?boar taint? that the meat from intact boars sometimes exhibits. Boar taint is chiefly cause by androstenone and skatole, two compounds that are mostly produced by sexually mature boars and are accumulated in the subcutaneous fat.

Barn i familjehem: En studie, om långtidsplacerade barns fysiska och psykiska hälsa, tonårsgraviditet, skolgång samt om föäldrarnas psykiska hälsa och mortalitet, i en undersökningskommun

The main purpose of the study was to analyse the well being of children placed in foster care for at least two years, in one sample municipality. An assessment was made of how the social service admistrated and took responsibility for these children in terms of schooling, physical and mental health. To further understand the situation of the children three areas of investigation were added concerning; teenage pregnancy, the mental health and mortality of the biological parents. To receive answers to those questions a qualitative interview method was used, with structured questions to social workers working with foster care. The author also studied journal notes and child investigations to receive a more comprehensive picture.

Kan mjuka golv i grisningsboxar minska skador på klövar och ben hos smågrisar?

The incidence of damage to the claws and legs in piglets caused by the floor in farrowing pens is a widely known problem and very common in today's pig herds. Although the association between floor and damage has been known for over 35 years, no suitable solution has been found to reduce the negative impact. The purpose of this study was to make a literature study to document the experiences of the use of different types of flooring in farrowing pens and also, in an own study, examine if soft floor in farrowing crates could lead to reduced damage to the claws and legs in piglets compared to concrete floor. The study was conducted in two herds, A and B. In each herd, farrowing pens with concrete floor and concrete floor with polyurethane coating were compared.
