The aim of this study was to verify whether secnidazole, given in a single oral dose (10 mg/kg), decreases or eliminates the excretion of Giardia duodenalis cysts. Holstein calves were raised from birth to 15 ± 2 days of age in individual stalls. Subsequently, 12 calves were grouped and housed in collective stalls. After seven days (day of life 21), we collected stool samples directly from the rectal ampulla in order to determine the degree of parasitic infection. Fecal examination was performed by a centrifugal-flotation technique, which allows for visualization and quantification of G...

The aim of the study was to determine if amniotic fluid cells of rats can be used to provide evidence of genotoxicity. In order to do that micronuclei formation was induced in rats during pregnancy after treatment with cyclophosphamide (CP), at different CP doses. On gestational day 19, we collected the amniotic fluid and determined the frequency of micronucleated cells (MNCs) from the offspring. Samples were centrifuged and placed on clean slides. The smears were observed with an epifluorescence microscope...

REVIEW
Heimo Mairbäurl
Neocytolysis is the selective destruction of those erythrocytes that had been formed during stress-erythropoiesis in hypoxia in order to increase the oxygen transport capacity of blood. Neocytolysis likely aims at decreasing this excess amount of erythrocytes and hemoglobin (Hb) when it is not required anymore and to decrease blood viscosity. Neocytolysis seems to occur upon descent from high altitude. Similar processes seem to occur in microgravity, and are also discussed to mediate the replacement of erythrocytes containing fetal hemoglobin (HbF) with those having adult hemoglobin (HbA) after birth...

Introduction Idiopathic epiretinal membrane (ERM) is a proliferation of cells formed on the internal surface of the retina and may cause a slow decrease in visual acuity (VA). The aim of this study was to evaluate the individual layers of the retina by optical coherence tomography (OCT) before and after vitrectomy with ERM peeling in order to refine surgical decision-making. Methods Forty-seven eyes of 45 patients (aged 55-87 years) with ERM were enrolled retrospectively from a tertiary referral centre. OCT examination was performed preoperatively and at a mean of 3...

Decomposing chemical interactions into bonds and other higher order interactions is a common practice to analyse chemical structures and gave birth to many chemical concepts despite the fact that the decomposition itself might be subjective in nature. Fragment molecular orbitals (FMOs) offer a more rigorous alternative to such intuition, but might be less interpretable due to extensive delocalisation in FMOs. Inspired by the Principal Component Analysis in statistics, we hereby present a novel framework, Principal Interacting Orbital (PIO) analysis, that can very quickly identify the "dominant interacting orbitals" that are semi-localised and easily interpretable while still maintaining the mathematical rigor...

INTRODUCTION: Hydrocephalus is defined as complex conditions influenced by genetic and environmental factors. Excluding hydrocephalus acquired from infection or brain tumors, congenital hydrocephalus with a genetic cause may occur isolated (hydrocephalus isolated, pure or non-syndromatic) or as a component of a genetic syndrome (syndromic hydrocephalus). OBJECTIVE: To present a syndromic congenital hydrocephalus with a known diagnosis, in order to be considered in the study of this pathology and to perform a review of hydrocephaly with a genetic cause...

New nutritional approaches to treat extreme premature babies have demonstrated relevant eviden ce of metabolic disturbances with early hypophosphatemia, especially in patients with intrauterine growth restriction (IUGR). They have shown late hypophosphatemia, as well, which is characteristic in the metabolic bone disease. A sytematic search of literature describing metabolic disturbances of phosphorus in preterm newborns is presented, related to the use of early parenteral nutrition and also in the context of metabolic bone disease...

INTRODUCTION: Prediction models may contribute to personalized risk-based management of women at high risk of spontaneous preterm delivery. Although prediction models are published frequently, often with promising results, external validation generally lacks. We performed a systematic review of prediction models for the risk of spontaneous preterm birth based on routine clinical parameters. Additionally, we externally validated and evaluated the clinical potential of the models. MATERIAL AND METHODS: Prediction models based on routinely collected maternal parameters obtainable during first 16 weeks of gestation were eligible for selection...

Unintended pregnancy is a public health concern throughout Europe. There is no common definition and no standard way to measure unintended pregnancy. Identifying unintended births is difficult and prevalence estimates vary depending on how and when the question is asked. Abortion rates are not a proxy and are themselves notoriously inaccurate. An estimated 34% (in Western Europe) to 54% (in Eastern Europe) of pregnancies are unintended. The determinants of unintended pregnancy are the length of the reproductive span and exposure to the risk of conception; the desired number of children and contraceptive use and effectiveness...

Acute kidney injury (AKI) is a common complication in the neonatal intensive care unit that causes a high mortality of preterm infants and various chronic kidney diseases in adulthood. Preterm infants have immature development of the kidneys at birth. The kidneys continue to develop within a specific time window after birth. However, due to various factors during pregnancy and after birth, preterm infants tend to develop AKI. At present, serum creatinine and urine volume are used for the assessment of kidney injury, and their early sensitivity and specificity have attracted increasing attention...

BACKGROUND: Numerous studies have investigated prenatal air pollution and shown that air pollutants have adverse effect on birth outcomes. However, which trimester was the most sensitive and whether the effect was related to maternal age is still ambiguous. OBJECTIVES: This study aims to explore the association between maternal air pollution exposure during pregnancy and preterm birth, and if this relationship is modified by maternal age. METHODS: In this retrospective cohort study, we examine the causal relationship of prenatal exposure to air pollutants including particulate matters, which are less than 10 µm (PM10 ), and ozone (O3 ), which is one of the gaseous pollutants, on preterm birth by gestational age...

Transgender or gender nonconforming (GN) persons identify themselves with a gender which is different from that correspondent to their birth sex. The demand for health services by families with transgender children or adolescents tends to increase. The prevalence of GN in children is unknown; however, it has been estimated to be > 1% in adolescents. Transgender persons are at increased risk of depression, suicide, illicit drug abuse, human immunodeficiency virus infection, and non-accidental injury. The most accepted model for the care of transgender persons assumes that these adverse outcomes are the consequence of social margination rather than the GI condition itself...

BACKGROUND: In 2015 the maternal mortality ratio for Ethiopia was 353 per 100,000 live births. Large numbers of women do not use maternal health services. This study aimed to identify factors influencing the use of maternal health services at the primary health care unit (PHCU) level in rural communities in Sidama zone, south Ethiopia in order to design quality improvement interventions. METHODS: We conducted a qualitative study in six woredas in 2013: 14 focus group discussions (FGDs) and 44 in-depth interviews with purposefully selected community members (women, male, traditional birth attendants, local kebele administrators), health professionals and health extension workers (HEWs) at PHCUs...

BACKGROUND: Increased patient mobility and restricted treatment of children with end-stage renal disease forced families from the former Eastern Bloc countries to flee with their children to Germany for adequate medical treatment. METHODS: In a case study, the patients' charts were analysed retrospectively. In structured interviews, parents and patients were asked about their flight routes to Germany, their medical treatment and their integration. RESULTS: From 2003 to 2013, eight children and adolescents with renal failure were treated with dialysis or renal transplantation in Erlangen...

In recent times, parents have become increasingly concerned, both subjectively and objectively, about their adolescents' body height/weight growth. Parent-adolescent interactions about this issue and the potential socio-psychological consequences of such interactions should be considered as an important influencing factor on the future of adolescents' sexual and reproductive health. To achieve a greater understanding of such concerns, it is necessary to further elucidate parents' experiences on this topic, so as to expand the existing literature...

The aim of this study was to evaluate observed and future inbreeding level in Polish Holstein-Friesian cattle population. In total, over 9.8 mln animals were used in the analysis coming from the pedigree of Polish Federation of Cattle Breeders and Dairy Farmers. Inbreeding level, as an average per birth year, was estimated with the method accounting for missing parent information with the assumption of year 1950 as the base year of the population. If an animal had no ancestral records, an average inbreeding level from its birth year was assigned...
