Investigation of awareness and anxiety levels of pregnant women during pandemic process

Objectives: It is currently unknown that how pregnant women deal with the Coronavirus disease and its results. The aim of this study is to evaluate the psychological impact of the coronavirus pandemic on pregnant women and to determine whether pregnant women have sufficient knowledge and awareness for a healthy antenatal process. Material and methods: This study was conducted at two centers. Regardless of the gestational age, a questionnaire was distributed to 1003 pregnant women in total, from which 51 original questions we prepared. Five hundred twenty-six participants were included in the study. The questionnaire was delivered using the QR code method. The questionnaires were answered online by participants via SurveyMonkey. Results: The period when anxiety was highest was the 2nd trimester, whereas women in the 1st trimester had the lowest level of anxiety. High levels of awareness were observed in patients with heart disease, but patients with diabetes mellitus had a high level of anxiety. Conclusions: It is important to maintain the mental and physical health of pregnant women, who are in a more delicate condition than other individuals in the society. In this regard, healthcare professionals have important duties such as taking necessary precautions and explaining the seriousness of the situation to pregnant women

WOS: 000326622600002The FT-IR and micro-Raman spectra of three n-alkyltrimethylammonium bromides (dodecyltrimethylammonium bromide (DTAB), tetradecyltrimethylammonium bromide (TTAB) and hexadecyl(cetyl)trimethylammonium bromide (CTAB)) in powder form were recorded in the regions 4000-550 cm(-1) and 3200-300 cm(-1), respectively. The optimized geometries and vibrational frequencies of DTAB, TTAB and CTAB have been carried out with ab initio Hartree-Fock (HF) and density functional theory method B3LYP calculations with the 6-31 G (d, p) basis set in the ground state. The comparison of the observed fundamental vibrational frequencies and calculated results for the fundamental vibrational frequencies of DTAB, TTAB and CTAB indicate that the scaled B3LYP method is superior compared to the scaled HF method

Can routine peripheral blood counts like neutrophil-to-lymphocyte ratio be beneficial in prediagnosis of testicular cancer and its stages?

Background: The purpose of this study was to assess the diagnostic role of preoperative hematological parameters, especially neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and mean platelet volume (MPV) in germ cell testicular malignancies and their prediagnostic role in staging of testicular cancer. Materials and Methods: In this cross-sectional retrospective study, we analyzed 39 patients who underwent radical orchiectomy due to a testicular cancer (Group 1) and 82 patients on whom varicocelectomy procedure was performed as control group (Group 2) between January 2006 and January 2016 in our clinic. Evaluation of the preoperative hematological parameters in both groups and also the subgroups in malignancy group according to histopathological stages was conducted in this study. Results: When the hematological parameters were compared, a statistically significant difference was found between the two groups in terms of neutrophil counts, NLR, PLR, and MPV. NLR and PLR were significantly higher and MPV was significantly lower in testicular cancer group compared to the control group. NLR was 3.1 ± 1.4 and 2.0 ± 1.5, PLR was 141.3 ± 53.2 and 115.7 ± 44.8, and MPV was 8.9 ± 1.0 and 9.3 ± 1.1 for testicular cancer and control groups, respectively (P < 0.05). Furthermore, differences were observed between only mean corpuscular volume, mean corpuscular hemoglobin, and MPV (P < 0.05) in different stages of malignancy. Conclusion: In accordance with these findings, NLR, PLR, and MPV may be helpful for prediagnosis of testicular malignancies. Hematological parameters will become important in the preoperative assessment for those patients

Alterations in some pancreatic functions, biochemical and haematological parameters in cattle due to traumatic reticuloperitonitis

Traumatic reticuloperitonitis (TRP), which results from penetration of reticulum and peritoneum by metallic foreign bodies, causes various clinical problems such as stasis of gastrointestinal system, vagal indigestion, thoracic, hepatic or reticular abcesses, pericarditis, peritonitis, myocarditis or other secondary problems (Ducharme, 1990; Ward and Ducharme, 1994; Radostits et al., 1994)

Investigation of the coagulation profile in calves with neonatal diarrhoea

In this study, 20 neonatal diarrhoeic and 10 clinically healthy neonatal calves were used. Venous blood samples were collected from each animal to determine platelet numbers, pH, partial pressure of carbon dioxide (pCO(2)), partial pressure of oxygen (pO(2)), saturated oxygen (O(2)SAT), content of carbon dioxide (ctCO(2)), actual bicarbonate (HCO(3)act), standard bicarbonate (HCO(3)std), and actual base excess (actBE) of plasma. Plasma samples were collected from each animal for the measurement of prothrombin time (PT), thromboplastin time (aPTT), thrombin time (TT), and the concentrations of fibrinogen and cross- linked fibrinogen degradation products (D-dimer). Blood pH, HCO3act, HCO3std, actBE, ctCO2, and O2SAT values were significantly (P < 0.001) lower in diarrhoeic calves than in healthy controls. PT, aPTT, and TT values were prolonged (P < 0.005), and fibrinogen concentration increased (P < 0.001) significantly in calves with diarrhoea than in control calves, while D- dimer concentrations were negative in both diarrhoeic and control calves. The results suggest that a compensatory type of disseminated intravascular coagulation (DIC) develops in diarrhoeic calves

The C-H center dot center dot center dot O and C-H center dot center dot center dot pi interactions within crystal packing were supported by Hirshfeld surface analysis. Spectral properties of trimebutine were investigated by using analysis techniques such as FT-IR, micro-Raman, NMR chemical shift and UV-Vis. spectroscopies. In order to investigate vibrational profile of the important functional groups within the compound, the detailed assignments of vibrational wavenumbers were performed by using potential energy distribution. Theoretical investigations on structural, spectroscopic, electronic, non-linear optical and thermochemical features were carried out with the DET/B3LYP method at the 6-311++G(d,p) basis set. The C-13 and H-1 NMR chemical shifts of each atom within the compound were studied both experimentally and theoretically. The UV-Vis. spectroscopic analysis of trimebutine was used to evaluate intra-molecular electronic transitions. The HOMOs and LUMOs analyses were done to determine the nature and origin of the pi ->pi* and n ->pi* electronic transitions. Additionally, the global reactivity descriptors were defined depending upon energy values of HOMO and LUMO. The pi ->pi* and n ->pi* hyperconjugative interactions between donor and acceptor groups were investigated by NBO analysis. According to the computed alpha(total), Delta alpha and beta(0) values in the static state of trimebutine single crystal, it exhibits an excellent non-linear optical material property.
