Malignant oral cancers do not commonly occur in pregnant women. But when they do, the presence of a foetus and maternal physiological changes complicate and limit the treatment options. Risk benefit assessment and balancing of them are always important. A 33-year-old woman, who was 25 weeks pregnant, presented with a squamous cell carcinoma on her tongue. She was clinically staged II (T2, N0 and M0). Discussions between the patient, surgical teams and obstetricians agreed to continue her pregnancy while managing the tumour...

OBJECTIVES: Primary retinal pigment epithelium (RPE) cells have a limited capacity to re-establish epithelial morphology and to maintain native RPE function in vitro, and all commercially available RPE cell lines have drawbacks of morphology or function; therefore, the establishment of new RPE cell lines with typical characteristics of RPE would be helpful in further understanding of their physiological and pathological mechanisms. Here, we firstly report a new spontaneously generated RPE line, fhRPE-13A, from a 13-week aborted foetus...

Porcine circovirus type 3 (PCV3) was recently proposed as a new porcine circovirus. It has been described by researchers in the USA and China and associated with porcine dermatitis and nephropathy syndrome, reproductive failure and systemic inflammation disease. The study reports the occurrence of the new virus in Italy. PCV3 was detected in the tissues of foetuses and stillborn piglets coming from two farms located in the Po Valley. The genome sequences of the two Italian strains share 99.7% to 97.8% of nucleotide identity with those available in GenBank...

Tritrichomonas foetus (T. foetus) is a flagellated protozoa that infects the distal ileum and proximal colon of domestic cats, as well as the urogenital tract of cattle. Feline trichomonosis is recognized as a prevalent cause of chronic diarrhea in cats worldwide. The suspected route of transmission is fecal-oral, with cats in densely crowded environments at highest risk for infection. Thus, the recommended strategy for minimizing spread of infection is to identify and isolate T. foetus-positive cats from the general population...

Tritrichomonas foetus (T. foetus) is a flagellated protozoan parasite that is recognized as a significant cause of diarrhea in domestic cats with a prevalence rate as high as 30%. No drugs have been shown to consistently eliminate T. foetus infection in all cats. Cysteine proteases (CPs) have been identified as mediators of T. foetus-induced adhesion-dependent cytotoxicity to the intestinal epithelium. These CPs represent novel targets for the treatment of feline trichomonosis. However, cats also produce CPs that are part of life-critical systems...

Prostaglandins (PGs) are the key mediators of several female reproductive functions, including luteolysis, ovulation, fertilization, implantation, pregnancy, and parturition. The present study was conducted in buffalo endometrial and luteal tissues between nonpregnant and two stages of pregnancy (29-38 days of pregnancy, 48-56 days of pregnancy) tissue samples. The genes involved from synthesis upto receptor level effect of PGs (PGF2α and PGE2) were studied for their relative mRNA expression. We have collected the endometrial and luteal tissues from slaughtered animals and confirmed the stages by external examination and crown vertebral rump length measurement of the foetus...

Handedness is a complex trait influenced by both genetic and non-genetic factors. Asymmetries of DNA methylation and gene expression in the developing foetus are thought to underlie its development. However, its molecular epigenetics are not well understood. We collected buccal cells from adult left- and right-handers (n = 60) to investigate whether epigenetic biomarkers of handedness can be identified in non-neuronal tissue. We associated DNA methylation in promoter regions of candidate genes with handedness direction...

Intervertebral disc (IVD) degeneration is often the cause of low back pain. Degeneration occurs with age and is accompanied by extracellular matrix (ECM) depletion, culminating in nucleus pulpous (NP) extrusion and IVD destruction. The changes that occur in the disc with age have been under investigation. However, a thorough study of ECM profiling is needed, to better understand IVD development and age-associated degeneration. As so, iTRAQ LC-MS/MS analysis of foetus, young and old bovine NPs, was performed to define the NP matrisome...

BACKGROUND: Plants produce secondary metabolites that often possess widespread bioactivity, and are then known as phytochemicals. We previously determined that several phytochemical-rich food-derived preparations were active against pathogenic foodborne bacteria. Trichomonads produce disease (trichomoniasis) in humans and in certain animals. Trichomonads are increasingly becoming resistant to conventional modes of treatment. It is of interest to test bioactive, natural compounds for efficacy against these pathogens...

Human and bovine trichomoniasis are sexually transmitted diseases (STD) caused by Trichomonas vaginalis and Tritrichomonas foetus, respectively. Human trichomoniasis is the most common non-viral STD in the world and bovine trichomoniasis causes significant economic losses to breeders. Considering the significant impact of the infections caused by these protozoa and the treatment failures, the search for new therapeutic alternatives becomes crucial. In this study the effect of diamines and amino alcohols in the in vitro viability of trichomonads was evaluated...

Neospora caninum is one of the most efficient transplacentally transmitted pathogens in cattle and is a cause of abortion in this domestic species. The invasion and proliferation of Neospora caninum in the placenta and its dissemination to the foetus are crucial events in the outcome of an infection. In the bovine placenta, the placentomes are formed by maternal caruncles, which are delimited by a maternal epithelium and foetal cotyledons, which are delimited by an epithelial layer named the trophoblast. These epithelia form a physical barrier against foetal infection...

The placenta is an intermediary organ between the female and the developing foetus. Some chemical substances, including the most harmful ones, exhibit the ability to accumulate in or penetrate through the placenta. The aim of the study was to determine the role of the placenta of the Baltic grey seal (Halichoerus grypus grypus) in the transfer of endocrine disrupting compounds (EDCs) - (bisphenol A, 4-tert- octylphenol, 4- nonylphenol), as well as total and organic mercury. 30 placentas were collected from grey seals pupping under human care at the Hel Marine Station in the years 2007-2016...

Holoprosencephaly is the most common embryonic brain defect. Foetuses who survive during intrauterine life are born with varying grades of brain and facial deformities. Extra craniofacial manifestations are common. Vertebral segmentation defects are rarely seen with holoprosencephaly, mainly in association with holoprosencephaly diencephalic hamartoblastoma (HDH) association. A female infant was born at term by normal delivery. Birth head circumference was below the 3rd percentile. Antenatal scan had showed microcephaly as the only abnormality...

A Almén, S Mattsson
This paper describes issues of concern for protecting foetuses and breast-fed children of occupationally exposed women in nuclear medicine from unnecessary exposure of ionising radiation. The protection principle is to ensure the same level of protection for the foetus and child as for the general public. Therefore international radiation protection standards recommend a dose constraint of 1mSv to a foetus during the remaining time of pregnancy after it is known/declared and a yearly dose constraint of 1mSv to a breast-fed child...

The number of caesarean sections increased significantly in Romania. In 2012, caesarean sections accounted for 41.2% of total births, according to a study of the Romanian National School for Public Health. This estimation is in agreement with the statistical data on caesarean sections recorded in one of the most important hospitals in Bucharest, Romania, Filantropia Hospital. Many factors have influenced the large number and sharply increasing trend of caesarean sections, from the historical ones, with roots in the communist regime, when abortions were outlawed, to current day doctors' medical practices and mothers' beliefs and fears related to the process of labor and the newborn's health...
