RESUMO

One of the most common causes of fetal alcohol spectrum disease (FASD) characterized with neurodevelopmental disorder and growth retardation, is the postnatal alcohol consumption. Since studies in literature are mainly focused on alcohol-induced effects on brain tissues, the molecular effects of postnatal alcohol consumption on fetal liver are not clarified yet. The aim of this study is to determine the postnatal alcohol consumption-induced structural and compositional changes on liver tissue and the antioxidant capacity of liver. Newborn mice were divided into 3 groups as control group without any treatment, alcohol group treated with 3.0 g/kg of ethanol in 0.02 ml/g of artificially enriched milk between Postnatal Days (PD) 3-20 and intragastric intubation control group which was intragastrically intubated in the same method as the alcohol group but without ethanol/milk. These postnatal days in mice refers prenatal period (third trimester) of gestation in human. The biomolecular changes were determined by ATR-FTIR spectral analysis of the samples, besides the biochemical measurement of total protein content and antioxidant capacity of liver tissue. The result of the current study shows that while there was a slight increase in total lipid content, significant decrease in unsaturated lipid and total protein contents and total antioxidant capacity of liver were observed in alcohol-treated group. Thus, it is concluded that postnatal alcohol treatment causes significant changes in tissue proteins and lipids by inducing lipid peroxidation and changes in protein conformations of the liver tissue. In addition to that alcohol consumption also reduce the antioxidant capacity of liver tissue.

RESUMO

Since COVID-19 pandemic has been continuously rising and spreading, several original contributions and review articles on COVID-19 started to appear in the literature. The review articles are mainly focus on the current status of the pandemic along with current status of the corona diagnosis and treatment process. Due to some disadvantages of the currently used methods, the improvement on the novel promising diagnosis and treatment methods of corona virus is very important issue. In this review, after briefly discussing the status of current diagnosis and treatment methods, we present to the scientific community, novel promising methods in the diagnosis and treatment of COVID-19. As with other novel approaches, first, the diagnosis potential of mass spectroscopy and optical spectroscopic methods such as UV/visible, infrared, and Raman spectroscopy coupled with chemometrics will be discussed for the corona virus infected samples based on the relevant literature. In vibrational spectroscopy studies, due to complexity of the data, multivariate analysis methods are also applied to data. The application of multivariate analysis tools that can be used to extract useful information from the data for diagnostic and characterisation purposes is also included in this review. The reviewed methods include hierarchical cluster analysis, principal component analysis, linear and quadratic discriminant analysis, support vector machine algorithm, and one form of neural networks namely deep learning method. Second, novel treatment methods such as photodynamic therapy and the use of nanoparticles in the in-corona virus therapy will be discussed. Finally, the advantages of novel promising diagnosis and treatment methods in COVID-19, over standard methods will be discussed. One of the main aims of this paper is to encourage the scientific community to explore the potential of this novel tools for their use in corona virus characterization, diagnosis, and treatment.

RESUMO

The severe sole effects of seizures on the cortical part of bone were reported in our previous study. However, the side effects of anti-epileptic drug therapy on bones has not been differentiated from the effects of the convulsive seizures, yet. This study provides the first report on differentiation of the effects of seizures and carbamazepine (a widely used antiepileptic drug) therapy on bones; 50 mg/kg/day drug was given to genetically induced absence epileptic rats for five weeks. Distinct bone regions including cortical, trabecular, and growth plate in each of tibia, femur, and spine tissues were studied using Fourier transform infrared (FT-IR) imaging and Vickers microhardness test. Blood levels of vitamin D and bone turnover biomarkers were also measured. According to the FT-IR imaging results, both seizure and carbamazepine-treated groups, more dominantly the drug-treated group, had lower mineral content with altered collagen crosslinks and higher crystallinity, implying reduced bone strength. Lower microhardness values also supported lower mechanical strength in bones. The most affected bone tissue and region from seizures and treatment was found as the spine and cortical, respectively. While there was a reduction in vitamin D and calcium levels in both seizure and carbamazepin-treated groups, significantly elevated PTH and bone turnover biomarkers were only seen in the drug-treated group.
