Effects of Transcranial Magneto-acoustic Electrical Stimulation on Discharge propagation in feed-forward neural network

The mammalian brain has an extremely complex, diversified and highly modular structure, and information dissemination in the modular brain network affects various brain diseases. Although a variety of neuromodulation techniques have been used to study the discharge characteristics of neural networks, the effects of transcranial magneto-acoustic electrical stimulation(TMAES) have rarely been mentioned. Based on the excitatory and inhibitory Izhikevich neuron model, we constructs a feed-forward neural network connected by electrical synapses and chemical synapses, and analyzes the firing frequency of the neural network under TMAES and magnetic stimulation and the differences in each layer types of firing patterns of neurons. The results showed that the discharge patterns of neurons in each layer were different, the discharge frequency of inhibitory neurons was higher than that of excited neurons, and the stimulation signal could be transmitted to the whole network layer.The maximum discharge frequency of neural network connected by electrical coupling can reach 0.94kHz, and the discharge frequency of neural network connected by chemical coupling is less than 0.5 kHz.With the increase of coupling degree, the discharge frequency of neurons in each network layer under TMAES is much greater than that under magnetic stimulation.When the induced current is less than 26.5μA/cm 2 , magnetic stimulation can promote the inhibitory neurons, and TMAES has a variety of regulatory effects on the inhibitory neurons in the neural network. The results show that TMAES has better regulation effect than magnetic stimulation, and the regulation effect is affected by neural network structure and stimulation parameters.

The Effects of Absorbing Materials on the Homogeneity of Composite Heating by Microwave Radiation

When cured in a microwave, flat thin composite panels can experience even heat distribution throughout the laminate. However, as load and geometric complexity increase, the electromagnetic field and resulting heat distribution is altered, making it difficult to cure the composite homogeneously. Materials that absorb and/or reflect incident electromagnetic radiation have the potential to influence how the field behaves, and therefore to tailor and improve the uniformity of heat distribution. In this study, an absorber was applied to a composite with non-uniform geometry to increase heating in the location which had previously been the coldest position, transforming it into the hottest. Although this result overshot the desired outcome of temperature uniformity, it shows the potential of absorbing materials to radically change the temperature distribution, demonstrating that with better regulation of the absorbing effect, a uniform temperature distribution is possible even in non-uniform composite geometries.

Harmful substances in cosmetic preparations

Cosmetic preparations contain a large number of ingredients. Some of them may have negative consequences, most often in the form of allergic reactions, skin irritations, hormonal disorders, increased risk of cancer. These chemicals are most often added to protect, soften, or otherwise make the product more usable. The aim of this study was to determine the presence of some potentialy harmful substances by qualitative analysis of cosmetic products using the GC-MS method and to compare results with the data stated on the product declaration. A total of 66 samples were analyzed: 10 baby shampoos and bath products, 26 cosmetic products for the axillary area and 30 samples of creams and serums. In 4 samples of baby shampoos and bath products (40 %) the presence of pottentialy harmful ingredients were proven (parabens and phenoxyethanol), while diethyl phtalate was detected in all samples but was not stated in any of the declarations of these samples. Parabens were detected in 7.7 % of the products for application in the axillary area, although were most often not declared on products, and diethyl phthalate was detected in 19 % of these samples. In 24 samples of creams and serums (80%) the presence of potentialy harmful substances buthylhydroxytoluene, cyclopentasiloxane, cyclotetrasyloxan, benzophenone, triethanolamine, phenoxyethanol, diethylphthalate was noted. This study has proven the misleading declarations. Phthalates were most often not declared on products. Better regulation of product declarations is needed, as well as stricter controls on the impact of primary packaging on product composition after packaging.

Association of LH/FSH ratio with menstrual cycle regularity and clinical features of patients with polycystic ovary syndrome

Background Understanding the global prevalence and phenotypic features of polycystic ovary syndrome (PCOS) is important as geographic factors and ethnic variations can significantly alter the clinical syndrome. The aim of this study was to determine and evaluate the luteinizing hormone/follicle-stimulating hormone ratio (LH/FSH) in women with PCOS during therapy on selected endocrine and biochemical parameters. Results Women with PCOS were included in the study and were classified into two groups: women without therapy (de novo) and women with therapy for PCOS. ESHERE/ASRM criteria that require the presence of two out of three criteria: ovulatory dysfunction, hyperandrogenism, and morphological PCOS detected by ultrasound diagnostics. Electrochemiluminescence immunoassay (ECLIA) was used for FSH and insulin analysis. The enzymatic method was used to analyze the biochemical profile. There was a significant difference between the two groups in terms of the LH/FSH ratio (2.56 vs. 2.41, P=0.043), glucose (6.23 vs. 5.12, P=0.003), insulin (19.21 vs. 7.35, P=0.000), IR (3.22 vs. 1.42, P=0.000), cholesterol (5.97 vs. 4.92, P=0.002), and LDL (3.56 vs. 2.56, P=0.001). The data suggest that patients with PCOS therapy have reduced hyperinsulinemia and insulin resistance. There was a significant correlation between the LH and FSH in the de novo group, as well as the correlation between hormone levels and LH/FSH ratio in both groups. Patients with PCOS therapy have a tendency for normal body weight and reduction of severe obesity compared to patients without therapy. Clinical features such as regular menstrual cycle and the prevalence of acne and hirsutism are not significantly different between groups. Conclusion PCOS cause irregularities of the menstrual cycle, the appearance of clinical manifestations, especially changes of LH/FSH ratio. Therapy for PCOS contributes to better regulation of endocrine and biochemical parameters, especially in the reduction of hyperinsulinemia, insulin resistance, and reduced LH/FSH ratio.
