The relationship between malignant skin diseases and health literacy and protection from sun and skin cancer: a case-control study

Objective: In recent years, skin cancer increased with the increase in sun exposure of people all over the world. In this study, we aimed to find out how much people in Turkey know about how to protect themselves from the sun and skin cancer, how they act to protect themselves from the sun and skin cancer, how they feel about sun protection, and how well they understand health issues. Patients and Methods: This study was designed as a case-control study. This study included 105 patients who were followed up in our clinic with malignant skin diseases (malignant melanoma (MM), basal cell carcinoma (BCC), and squamous cell carcinoma (SCC)) between March 2020 and March 2021. Our control group comprised 105 healthy volunteers. This study collected data with a data collection form and the Health Literacy Scale. Results: The results showed that the mean knowledge level of the control group was higher than that of the case group. Similarly, the mean behavior of protection from sun and skin cancer and mean sun protection attitude is higher in the control group than in the malignant skin diseases group. There is a statistically significant difference between the mean health literacy levels of the malignant skin disease group and the control group. The mean health literacy levels of the malignant skin disease group are lower than the control group. There is a statistically significant effect of health literacy, age, knowledge level of protection from sun and skin cancer, and behavior of protection from sun and skin cancer on the probability of skin cancer. Conclusions: Increasing the level of knowledge may positively affect compliance with skin cancer preventive measures and decrease skin cancer-related morbidity and mortality

Dose-dependent effects of specific egg-yolk antibodies on diarrhea of newborn calves

In a field trial on a farm in Turkey, we tested whether specific egg-yolk antibodies had a prophylactic effect on neonatal diarrhea. Owing to its antibody spectrum, this egg powder was very suitable for this farm since mainly rotavirus was identified, Regardless of the dosage (2 g, 4 g, or 8 g egg powder), the calves(n = 164) which received specific egg-yolk antibodies via the whole egg during the first 14 days of life showed significant improvements in risk and duration of diarrhea and in body weight gain compared with calves of the control group (n = 80) which had not received any egg powder, These significant differences in body weight still persisted after 3 months of life, The mortality risk in the control group amounted to 8.8%, while in all egg powder groups (n = 164) only one calf died as a result of diarrhea, Breed-dependent differences in the parameters were not observed

Synthesis of (3,6-dihydro-2H-pyran-2-yl)phosphonate derivatives and investigation of catalyst effect on frontier molecular orbitals using DFT method

<p>Hetero Diels-Alder (HDA) reactions between 2,3-dimethyl-1,3-butadiene and diethyl ester of aroyl phosphonates catalyzed by AlCl₃ to afford (3,6-dihydro-2H-pyran-2-yl) phosphonate derivatives were investigated. Aroyl phosphonates with electron-withdrawing groups generally resulted in better isolated chemical yields. A stoichiometric amount of AlCl₃ rather than a catalytic amount was necessary to activate the cycloaddition reaction. The amount of AlCl₃ catalyst and its effect on LUMO of ethyl ester benzoyl phosphonate were also investigated by performing density functional theory (DFT) (B97D/6-31+G(d,p)) computations in dichloromethane. An increased loading of AlCl₃ induced a considerable decrease in the LUMO energy of ethyl ester of benzoyl phosphonate. The computed Gibbs free activation energy is 17.03 kcal/mol in DCM at 0°C using the same computational level.</p
