Firstly, bovine whey proteins was pretreated by ultrasonic techniques, and its secondary structure was detected by circular dichroism. The pretreated whey proteins was used as the fermentation substrate by Kluyveromyces marxianus for microbial transformation. The single factor design and Box-Behnken Design (BBD) were carried out with the aim to optimize culture temperature, initial pH, inoculum volume and rotation speed. After optimization process, culture temperature, initial pH, inoculum volume and rotation speed were determined. Under culture temperature 35 °C, pH 7.25, inoculum level 10% and shaking speed 150 rpm, the α-LA and β-LG antigenicity in bovine whey proteins were reduced by 29% and 53%, respectively. The findings showed that combined with microbial fermentation for hydrolysis of whey proteins, ultrasonic pretreatment can be used in order to produce hypoallergenic bovine whey proteins.
Conclusion: Micro-ultrasound is a more convenient and cost-effective method in real-time imaging during the biopsy procedure in detecting clinically significant prostate cancer. Although micro-ultrasound has shown promising results, more clinical data and comprehensive analysis are still needed.
ConclusionEmergency physicians should know about this potential complication as an important differential diagnosis resulting from acute abdominal complaints in patients with ventriculoperitoneal shunts.
A Kentucky law requiring doctors to perform ultrasounds and show fetal images to patients before abortions was upheld Monday by the U.S. Supreme Court.
Resumo O aneurisma de art éria poplítea (AAP) é o mais frequente dos aneurismas periféricos, correspondendo a 85% do total de aneurismas. Normalmente, são assintomáticos, e o diagnóstico, em geral, é feito por meio do exame físico, tendo uma maior incidência no sexo masculino e em idosos. São bilaterais em 50% dos casos e, em 60% das vezes, estão associados a aneurisma de aorta abdominal. Apresentamos um paciente do sexo masculino com 72 anos de idade, com duas massas pulsáteis em ambas as regiões poplíteas, assintom&aac...

The U.S. Supreme Court on Monday left in place a Kentucky restriction requiring doctors to show and describe ultrasound images to women seeking an abortion, turning away a challenge arguing that the measure violates the free speech rights of physicians.
