The genotoxic effects caused by surfactants in mammals and fish were at similar levels to those found in the ethanol treatment. Therefore, this study demonstrated that the use of surfactants T20 and T80 in Oreochromis niloticus anesthesia presented neither a reduction nor a considerable increase of the toxicity when compared to the commonly used ethanol; however, an increase in anesthetic effectiveness was observed throughout the experiment.Separation of oil-water (OW) emulsions is investigated using a photocatalytic demulsification approach. Experiments were conducted using two types of photocatalysts, namely, ZnO and TiO2. The emulsion samples were prepared with oil to water ratios of 13, 11, and 31 and using nonionic surfactant Tween 20 as an emulsifier. The demulsification efficiency was determined using a direct time varying phase separation measurement, while dynamic light scattering (DLS) and microscope imaging (MI) were used to determine the change in emulsion droplets size. The investigation results showed that all the emulsions were destabilized and separated within 30-90 min with demulsification efficiency that ranged from 38 to 90%. Paxalisib On the other hand, untreated control samples remained stable with no phase separation for more than 24 h. For most of the studied experimental conditions, TiO2 nanoparticles gave better demulsification results than ZnO. Modeling of the batch demulsification kinetics for both systems agreed satisfactorily with the experimental measurements. This could allow its further extension towards design of continuous processes for potential implementation in treatment of industrial oily wastewaters.Chlorpyrifos (ChF) is an organophosphate pesticide that is widely used in agricultural fields and indoor for controlling pests. Aquatic ecosystems are the recipients of various pesticide residues due to leaching spray drift and agricultural runoff and pose toxicity for aquatic organisms. Therefore, the current study was designed to investigate the oxidative stress enzymes and histological alterations in the vital organs of tilapia due to ChF exposure. LC50 (24 h) was calculated as 52.78 μg/l by exposing tilapia with different acute concentrations of ChF. For assessment of sub-lethal toxicity of ChF, the fish were divided into four groups (ChF1, ChF2, ChF3, and control group). ChF1 group was treated with 1/15th of LC50, whereas ChF2 and ChF3 groups were treated with 1/10th and 1/5th of LC50, respectively for 14 days. After that, ChF induced changes in oxidative stress enzymes and histological alterations were evaluated. It was found that the level of glutathione S-transferase (GST), catalase (CAT), and superoxide dismutase (SOD) increased significantly in the liver of ChF-treated tilapia. Histological study of liver tissues showed an increased number of Kupffer cells, hydropic degeneration, necrosis, and hemorrhage. In the spleen of treated fish, increased melanomacrophage centers, necrosis, and congestion were detected. Disorganized muscle fibers, cardiac muscle fiber degeneration, and coagulative necrosis were observed in the heart of ChF-treated fish. It is concluded that sub-lethal concentrations of ChF can induce oxidative stress and histological alterations in the tissues of tilapia.The distinction between severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-related and community-acquired pneumonias poses significant difficulties, as both frequently involve the elderly. This study aimed to predict the risk of SARS-CoV-2-related pneumonia based on clinical characteristics at hospital presentation. Case-control study of all patients admitted for pneumonia at Semmelweis University Emergency Department. Cases (n = 30) were patients diagnosed with SARS-CoV-2-related pneumonia (based on polymerase chain reaction test) between 26 March 2020 and 30 April 2020; controls (n = 82) were historical pneumonia cases between 1 January 2019 and 30 April 2019. Logistic models were built with SARS-CoV-2 infection as outcome using clinical characteristics at presentation. Patients with SARS-CoV-2-related pneumonia were younger (mean difference, 95% CI 9.3, 3.2-15.5 years) and had a higher lymphocyte count, lower C-reactive protein, presented more frequently with bilateral infiltrate, less frequently with abdominal pain, diarrhoea, and nausea in age- and sex-adjusted models. A logistic model using age, sex, abdominal pain, C-reactive protein, and the presence of bilateral infiltrate as predictors had an excellent discrimination (AUC 0.88, 95% CI 0.81-0.96) and calibration (p = 0.27-Hosmer-Lemeshow test). The clinical use of our screening prediction model could improve the discrimination of SARS-CoV-2 related from other community-acquired pneumonias and thus help patient triage based on commonly used diagnostic approaches. However, external validation in independent datasets is required before its clinical use.
Postoperative hypocalcemia after total thyroidectomy (TT) still remains common. This prospective observation study examined the role of intraoperative time period (IOP) and intravenous fluids (IVF) in transient and permanent (> 6months) hypocalcemia post-TT.

Consecutive patients (n = 328; age = median (IQR); 34 (15) years; MF = 65263) with benign or malignant thyroid disease undergoing TT were evaluated for IOP, intraoperative IVF, serum corrected calcium, intact parathormone (iPTH), and 25-hydroxyvitamin D (25OHD) levels at baseline, 48h, and 6months post-TT.

The incidence of symptomatic transient and permanent hypocalcemia post-TT was 33.5% and 7.9% respectively. In multivariate logistic regression analysis, the independent risk factors for transient hypocalcemia were IOP (odds ratio 11.6), 48-h iPTH (4.8), IVF (2.9), hyperthyroidism (2.8), and percent calcium decline (1.07), while 25OHD deficiency increased the risk by 10.5 odds in subset with preoperative hypocalcemia. In receiver operating characteristic analysis, IOP, and IVF strongly predicted transient hypocalcemia with a threshold of 123min and 1085mL. Area under the curve, sensitivity, and specificity were 0.883 (95% CI 0.838-0.928), 88.1%, and 74.4% and 0.883 (0.840-0.926; each P = 0.001), 84.4%, and 74.4% respectively. Serum 48-h calcium < 7.8mg/dL was the only reliable predictor of permanent hypocalcemia.

Operative duration > 123min and IVF > 1085mL increased the risk of transient hypocalcemia post-TT manyfold but not permanent hypocalcemia. Routine intraoperative identification, preservation of viable in situ parathyroid glands, and laryngeal nerves increased IOP and rates of transient hypocalcemia but improved long-term outcome.
