Crimes against health.
Býčková, Michaela ; Jelínek, Jiří (advisor) ; Vanduchová, Marie (referee)
The main goal of this diploma thesis was to summarize crimes against health in accordance to Chapter I Title II of the Criminal Code. Firstly I focused on history of the crimes against health. As these crimes were present during the whole human being, my goal was to describe the main historical milestones from the beggining of the Czech state until the publication of the present Criminal Code. In another chapter I described crimes against health from the criminological point of view. I defined individual types of offenders of these crimes, their motivation, causation why are they commiting crimes and last but not least the possible way how to prevent these crimes. Third chapter contains description of the main elements in crimes against health. There are four obligatory signs of every criminal offence. The object, the subjective point, the objective point and the perpetrator. Main part of this work is devoted to the analysis of the particular crimes according to Chapter I Title II of the Criminal Code. I devided this part systematicly into two chapters - intentional crimes and crimes caused by negligance. Chapter about the crimes caused by negligance describes more detailed crimes against health caused by road accidents, doctors and sportsman. There is an extensive practise of the courts in this...

Utilization of experimental games' methods in the study of cooperation, altruism and fairness and their biological predictors
Nováková, Julie ; Flegr, Jaroslav (advisor) ; Lindová, Jitka (referee)
Cooperative, altruistic and fairness-exhibiting behavior is an important topic in evolutionary and behavioral biology and the mechanisms leading to its evolution, ultimate as well as proximate precursors, are subject of much research in biological as well as social sciences, theoretical as well as experimental work. In light of the life history theory, I focused on the connection of one's health state and cooperative behavior in humans and tested the hypothesis that more healthy individuals would manifest more cooperative tendencies (as they would have more opportunities of future interactions and long-term benefits), and conversely. The data, obtained from a sample of university students engaged in experimental games (Dictator Game, Ultimatum Game, Expanded Ultimatum Game, Trust Game, and Reversed Dictator Game) and a health and personality-focused questionnaire, did not corroborate this hypothesis. My other hypotheses - that better memory and lower temporal discounting would be related to more cooperative behavior (stemming from the conditions for reciprocal cooperation) - were supported by the data, albeit only partially in the case of memory. I also used the data from the five experimental games to briefly describe the proportions of different types of behavior (self-regarding, altruistic,...

Acetyl - CoA carboxylase - evolution and inhibition
Chalupská, Dominika ; Čeřovská, Noemi (advisor) ; Plchová, Helena (referee) ; Vlček, Čestmír (referee)
Abstract
Acetyl-CoA
carboxylase
(ACC)
is
a
key
enzyme
of
fatty
acid
metabolism
with
multiple
isozymes
often
expressed
in
different
eukaryotic
cellular
compartments.
In
agriculture,
inhibitors
of
plastid
ACC
are
used
as
efficient
herbicides
against
grass
weed.
However,
grass
weed
populations
resistant
to
aryloxyphenoxypropionate
(APP)
and
cyclohexanedione
(CHD)
herbicides
represent
a
major
problem
for
sustainable
agriculture.
Using
PCR
and
sequencing
it
was
found
out
that
five
amino
acid
substitutions
in
plastid
ACC
were
correlated
with
herbicide
resistance
of
Avena
sterilis
ssp.
ludoviciana
Durieu
populations
from
the
northern
grain-growing
region
of
Australia:
Trp-1,999-Cys,
Trp-2,027- Cys,
Ile-2,041-Asn,
Asp-2,078-Gly
and
Gly-2,096-Ala.
We
showed,
using
a
yeast
gene- replacement
system,
that
these
single-site
mutations
also
confer
herbicide
resistance
to
wheat
plastid
ACCase:
Asp-2,078-Gly
confers
resistance
to
APPs
and
CHDs,
Trp-2,027-Cys
and
Ile-2,041-Asn
confer
resistance
to
APPs,
and
Trp-1,999-Cys
confers
resistance
only
to
fenoxaprop.
These
mutations
are
very
likely
to
confer
resistance
to
any

Determination of phtalates via GC-MS in children´s pacifiers and a risk of their transport to human´s digestive system.
CIHLÁŘOVÁ, Tereza
This bachelor thesis deals with the problems of phthalates analysis, or phthalic acid esters, contained in children´s pacifiers. These organic substances have been used for many years as a plasticizers of plastics, rubber and PVC. Since phthalates are not chemically bound in the polymers they are easily released into the environment. Phthalates have negative health effects on the human body, especially on the reproductive and endocrine system. Some phthalates behave in the body like xenoestrogens, mostly in males, since they can affect the development of genitals in infancy. A long-term intake of these substances leads to their accumulation in the organism, and thus there is a risk of developing chronic diseases. A long-term exposure to high doses over a long period of time increases the toxicity of the plasticisers, especially after a direct contact of young children with the pacifiers. The main aim of this bachelor thesis was description and assessment of the effects of phthalates on the human organism. Phthalates were determined by gas chromatography method with the mass spectrometric detection (GC-MS), after the extraction of plasticizers with an organic non-polar solvent. The phthalate analysis was conducted in two different parts of each baby pacifiers, that were randomly selected commercially available products. Phthalates were detected in most investigated samples, similar concentrations levels were found in both parts of the pacifiers.

Bioaerosols
Hladíková, Dita ; Hovorka, Jan (referee) ; Hůnová, Iva (advisor)
Bioaerosols and aerobiology are similar terms associated with the study of chemical, physical and biological fields. Bioaerosols in the air is a part of the aerosol containing particles of biological origin, such as viruses, bacteria, fungal spores, house dust mites and pollen. These particles can affect health of living organisms in terms of allergies, toxicity, carcinogenicity or infection and ultimately affect the planet's climate system because of acting as condensation nuclei for the formation of precipitation. The most studied biological effects of the above-mentioned on human health are reported respiratory symptoms and pulmonary diseases. This is due to almost continuous human exposure to these particles, both in the domestic environment, which includes mainly house dust mites, animal allergens, molds and bacteria, and outdoors, where a person is exposed to pollen and outdoor molds. In the case of interference with the climate system of the Earth there is a direct or indirect influence. Indirect effects include the creation of clouds and precipitation, which has the effect on the hydrological cycle of the planet. Scattering and absorption of solar radiation is considered a direct effect on climate change. Foreign literature was a crucial source of information on this topic.

The effect of purging on lipid content and composition of common carp
TRYBULOVSKÝ, Filip
This bachelor's thesis deals with purging of common carp (Cyprinus carpio L.), and examines its effect on the content and composition of fatty acids and fat content. The goal of this experiment is to prove that purging has a positive effect on the carp flesh quality; that the progress and result of purging can be influenced by the input fish quality; and determining optimum time for carp purging with regard to the content and composition of fatty acids. The raising of fish was done at the ponds of the Blatenská ryba, spol. s r. o. company. The purging itself took place at the Faculty of Fisheries and Protection of Waters at Vodňany. The fish were divided into three groups according to supplementary feed. The O group was supplementary fed by cereals, the KP group by mixture of KP Len (containing rapeseed and linseed) and the PP group was left with natural diet. The fish were sampled after being placed in the purging pond. This sampling was done on the following days: 0, 14, 28, 42, 56 and 70. The fat and fatty acid analyses were performed by the Swedish University of Agricultural Sciences at Uppsala, Sweden. The KP group has demonstrably better composition of fatty acids than the O group, and its total fat content is sufficient also. The PP group also has a good composition of fatty acids, however, its total fat content is too low. The experiment has proven that purging has a positive effect on the flesh quality, if the fish are purged for a certain time period. The optimum time for carp purging, as determined by us in this experiment, is 14 - 21 days, in this period the fish have the excellent composition of omega-3 PUFA, together with a sufficient total fat content.
