These antibodies produced a variety of binding patterns on the random peptide arrays. When unblinded, the antibodies with polyspecific binding were the ones with the greatest therapeutic activity. The protein target to these therapeutic monoclonals is still unknown but using common sequence motifs from the peptides we predicted several human and mouse proteins. The same five highest proteins appeared in both mouse and human lists.BACKGROUND Preventive chemotherapy with praziquantel (PZQ) is the cornerstone of schistosomiasis control. However, a single dose of PZQ (40 mg/kg) does not cure all infections. Repeated doses of PZQ at short intervals might increase efficacy in terms of cure rate (CR) and intensity reduction rate (IRR). Here, we determined the efficacy of a single versus four repeated treatments with PZQ on Schistosoma mansoni infection in school-aged children from Côte d'Ivoire, using two different diagnostic tests. METHODS An open-label, randomized controlled trial was conducted from October 2018 to January 2019. School-aged children with a confirmed S. mansoni infection based on Kato-Katz (KK) and point-of-care circulating cathodic antigen (POC-CCA) urine cassette test were randomly assigned to receive either a single or four repeated doses of PZQ, administered at two-week intervals. The primary outcome was the difference in CR between the two treatment arms, measured by triplicate KK thick smears 10 weeks after the first n increase in adverse events. Using POC-CCA, the observed CR was significantly lower than measured by KK, indicating that PZQ may be considerably less efficacious as concluded by KK. Our findings highlight the need for reliable and more accurate diagnostic tools, which are essential for monitoring treatment efficacy, identifying changes in transmission, and accurately quantifying the intensity of infection in distinct populations. In addition, the higher CR in the intense treatment group suggests that more focused and intense PZQ treatment can help to advance schistosomiasis control.

The use of captive bats in research has intensified over the past decade as researchers aim to examine the virus-reservoir host interface. In this study, we investigated the effects of captivity on the fecal bacterial microbiome of an insectivorous microbat, Mops condylurus, a species that roosts in close proximity to humans and has likely transmitted viral infections to humans. Using amplicon 16S rRNA gene sequencing, we characterized changes in fecal bacterial community composition for individual bats directly at the time of capture and again after six weeks in captivity. We found that microbial community richness by measure of the number of observed operational taxonomic units (OTUs) in bat feces increases in captivity. Importantly, we found the similarity of microbial community structures of fecal microbiomes between different bats to converge during captivity. We propose a six week-acclimatization period prior to carrying out infection studies or other research influenced by the microbiome composition, which may be advantageous to reduce variation in microbiome composition and minimize biological variation inherent to in vivo experimental studies.The heterotrophic microalgae Crypthecodinium cohnii was usually cultivated in complex medium containing glucose, yeast extract and sea salt. For the preparation of DHA with highest purity, a new defined medium without the yeast extract was developed. Different inoculated densities, C/N ratios, temperatures, culture volumes and glucose additions were investigated to optimize the algal growth rate and DHA production. The growth period in C. cohnii was shortened from 12-14 days to 7-8 days, the OD600 was enhanced from 2.0 to 3.0, the glucose consumption was accelerated and used up on day 3-4, and the DHA content in culture were increased from 10 to 45 nmoles/300 μl batch. It was found that C. cohnii had optimal growth and DHA accumulation in 25 °C, 0.2 inoculated density, 5-10 C/N ratio, 51 air/culture volume ratio. This is the first time DHA production using C.cohnii has been optimized in synthetic medium. This allows preparation of uniformly radiolabeled 13C- and 14C-DHA.BACKGROUND About one-third of the cervical cancer cases in Sweden occur in women over the age of 60. The primary aim of this study was to analyze the incidence of HPV, and HPV related dysplasia, in elderly women who had an HPV negative test at the age of 60 years or older. METHODS From October 2004 to June 2019, 1784 women aged 60-90 years were sampled for an HPV test when attending an outpatient gynecology clinic. Of these women, 827 HPV-negative women had two or more HPV tests at intervals of three months to eleven years (mean 3.2 years). The women with positive results had a repeat HPV test and cytology after 2.5 months on average. Those with a positive repeat HPV test were examined by colposcopy and biopsy. FINDINGS The overall prevalence of HPV was 5.4%, (95%CI 4.4-6.6, 96/1784). The incidence of HPV in the 827 women, who were HPV negative in their first test, was 2.4% (95%CI 1.5-3.8, n = 20). At the repeat test 1.2% remained positive (95%CI 0.6-2.3, n = 10). read more HPV-related dysplasia diagnosed by histology was found in 1.2% (95%CI 0.6-2.3, n = 10) of the 827 women. CIN2+ was found in 0.5% (95%CI 0.2-1.3, n = 4). In the repeat HPV test 52.6% 10/19) were HPV positive. The time between an HPV negative test and an HPV positive test and CIN2+ was on average 45.5 months (range 10-85 months). The positive predictive value (PPV) for CIN2+ was 20.0% in the first positive HPV test and 40.0% in the repeat HPV test. The women with CIN2+ had normal cytology. No cancer or glandular dysplasia was detected. INTERPRETATION In this study older HPV-negative women were at risk of becoming HPV positive. Among the women who were HPV positive in a repeat test, there was a high risk of dysplasia.BACKGROUND Anemia, which is a major public health problem worldwide, represents a decline in the oxygenation function, and can therefore be related to low strength. However, hemoglobin cannot repair muscles directly, but is beneficial only in a supportive role. Previous studies on the relationship between handgrip strength and anemia have been controversial. Thus, we aimed to analyze the association between handgrip strength and anemia in Korean adults. METHODS This cross-sectional study used the 2013-2017 data from the 6th and 7th Korean National Health and Nutrition Examination Survey (KNHANES) that included 16,638 Korean adults, aged ≥19 years, who met the inclusion or exclusion criteria. Differences in sociodemographic factors (sex, age, education, income, and employment), lifestyle factors (alcohol consumption, smoking, and physical activity), and illness and health factors [body mass index (BMI), vitamin intake, iron intake, comorbid illnesses, and handgrip strength] by existence of anemia, were analyzed using the Chi square test.
