Ochratoxin A (OTA) is a toxic metabolite produced mainly by Aspergillus and Penicillium species. A quantitative method was developed for the rapid, simple, and sensitive detection of OTA in corn by quantum dots-based fluorescent immunochromatographic assay (QDs-ICA). The CdSe/ZnS QDs-labelled anti-OTA monoclonal antibody (mAb) conjugates were designed as the fluorescent signal probe. The QDs-ICA included the designation of test line (T line) and control line (C line), which were sprayed with optimal concentrations of the OTA-OVA and staphylococcal protein-A (SPA), respectively. Under the optimal experimental conditions, the QDs-ICA exhibited excellent specificity and good accuracy and precision. For qualitative detection, the cut-off value for the T line of the visual detection method was 2.5 ng/mL. For quantitative detection, the linear regression equation of the standard curve was y = 0.366x + 0.514 with a reliable correlation coefficient (R2 = 0.992). Moreover, the 50% inhibition value (IC50) of the QDs-ICA was 0.91 ng/mL, the limit of detection (LOD) was 0.07 ng/mL, and the detection range was 0.05 to 10 ng/mL. In addition, the recovery rates ranged from 91.82 to 100.35% with a coefficient of variation (CV) below 3% for intra-assay, whereas the recovery rates for inter-assay changed from 94.29 to 104.62% with a CV below 10%. These results indicate that the QDs-ICA can serve as a potential large-scale preliminary device for rapid determination of OTA. Using CdSe/ZnS QDs as the fluorescent signal for quantum dots-based fluorescent immunochromatographic assay, the QDs-ICA provided a novel method for the rapid simultaneous qualitative and quantitative determination of OTA.The original article can be found online.Trauma is one of the leading causes of mortality in pregnant women and significantly increases the likelihood of an unwanted termination of pregnancy. Particularly in severe trauma with an increased risk of significant maternal injuries, computed tomography (CT) remains the imaging modality of choice as it is comprehensively available, quick to carry out and has a high diagnostic accuracy in the detection and classification of life-threatening trauma-associated pathologies compared to other imaging techniques. Considering the radiation-associated risks, it is unlikely that a single, monophasic CT in the emergency trauma room will exceed the threshold of deterministic radiation damage; therefore, fetal malformations or fetal loss are not to be expected; however, there is a low stochastic risk for the delayed occurrence of radiation-induced cancer both for the child and the mother that can be considered small in comparison to missed or delayed diagnoses after severe trauma. Intravenous, nonionic iodinated contrast agents are not contraindicated during pregnancy and should be administered whenever their use would also be considered appropriate in a nonpregnant patient; however, unnecessary scans and, if possible, multiple contrast agent phases should be avoided in order to reduce radiation. Magnetic resonance imaging (MRI) has a major role in the subacute setting and constitutes an excellent problem solver for specific questions, such as the evaluation of discoligamentous injuries of the spine. Its use is deemed acceptable at any stage of pregnancy when the required information is considered important for the management of further treatment. Due to potential teratogenic effects of MRI contrast media containing gadolinium on the fetus, including an increased likelihood of fetal loss, they should only be administered with great caution and under strictly defined indications.External otitis is one of the most common infections in the head and neck region, as about 10% of all people suffer from it at least once during their life. It is an infection of the cutis and subcutis of the outer ear canal caused by bacteria, viruses, and fungus as well as allergens or degenerative toxic substances. A concomitant infection of the eardrum (myringitis) may develop. Patients typically present with unilateral, rarely bilateral, earache (otalgia), with accompanying hearing loss and sometimes discharge from the ear (otorrhea). In general, otalgia is one of the most common reasons for consulting a general practitioner in Germany (4.2-7.7%), especially for children up to 14 years.Since its first appearance in December 2019, the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has spread all over the world at a rapid pace causing the coronavirus disease 2019 (COVID-19). Originating from the Chinese province Hubei, more than 29.4 million people globally have now been confirmed to have contracted the coronavirus and more than 930,000 patients have died so far from COVID-19 (situation as of 15 September 2020). The virus is mainly spread during close contact by small droplets and aerosols. During the close contact in medical examinations, such as echocardiography, the risk of contracting the virus is increased. Therefore, the use of personal protective equipment is recommended for the protection of patients and medical personnel alike. This article summarizes the current recommendations of international societies and describes the local implementation in Austria.Robotic surgical procedures have been implemented and have become an important development in pancreatic surgery with an increasing acceptance worldwide. Nearly all types of pancreatic surgery have now been performed robotically and especially standardized resections, such as distal pancreatectomy (RDP) and partial pancreatoduodenectomy (RPD) have gained importance despite a potentially long learning curve and high associated procedural costs. The present review article summarizes the available literature and evidence on the respective procedures focused on their use for indications of malignancy.
Leiomyomas of the urinary bladder are rare tumors. Submucosal leiomyomas, when small and easily accessible, can be treated with transurethral resection, while unfavorably positioned or larger leiomyomas may be treated through an abdominal approach. Selinexor mouse In these cases, a laparoscopic approach for intravesical surgery is an alternative that may be considered. We aim to demonstrate a novel transvesical laparoscopic approach to bladder leiomyoma excision with a video.
A 45-year-old woman with urinary symptoms and a 40-mm submucosal bladder leiomyoma located at the interureteric ridge was referred to our hospital (tertiary referral hospital). Due to the location and size of the leiomyoma, and to increase the probability of complete resection, a transvesical laparoscopic approach was decided. A step-by-step video is presented to describe the surgical technique.
There were no intra- or postoperative complications. The patient was discharged 48h after the surgery. At 60months' follow-up, the patient remains asymptomatic.
