The presented strategy unlocks a new route for the development of rapid COVID-19 diagnostic tools.The association of mortality with the early humoral response to SARS-CoV-2 infection within the first few days after onset of symptoms (DAOS) has not been thoroughly investigated partly due to a lack of sufficiently sensitive antibody testing methods. Here we report two sensitive and automated testing-on-a-probe (TOP) biosensor assays for SARS-CoV-2 viral specific total antibodies (TAb) and surrogate neutralizing antibodies (SNAb), which are suitable for clinical use. The TOP assays employ an RBD-coated quartz probe using a Cy5-Streptavidin-polysacharide conjugate to improve sensitivity and minimize interference. Disposable cartridges containing pre-dispensed reagents require no liquid manipulation or fluidics during testing. selleck The TOP-TAb assay exhibited higher sensitivity in the 0-7 DAOS window than a widely used FDA-EUA assay. The rapid and automated TOP-SNAb correlated well with two well-established SARS-CoV-2 virus neutralization tests. The clinical utility of the TOP assays was demonstrated by evaluating early antibody responses in 120 SARS-CoV-2 RT-PCR positive adult hospitalized patients. Higher TAb and SNAb positivity rates and more robust antibody responses at patient's initial hospital presentation were seen in inpatients who survived COVID-19 than those who died in the hospital. Survival analysis using the Cox Proportional Hazards Model showed that patients who had negative TAb and/or SNAb at initial hospital presentation were at a higher risk of in-hospital mortality. Furthermore, TAb and SNAb levels at presentation were inversely associated with SARS-CoV-2 viral load based on concurrent RT-PCR testing. Overall, the sensitive and automated TAb and SNAb assays allow the detection of early SARS-CoV-2 antibodies which associate with mortality.Early-stage diagnosis is a crucial step in reducing the mortality rate in oral cancer cases. Point-of-care (POC) devices for oral cancer diagnosis hold great future potential in improving the survival rates as well as the quality of life of oral cancer patients. The conventional oral examination followed by needle biopsy and histopathological analysis have limited diagnostic accuracy. Besides, it involves patient discomfort and is not feasible in resource-limited settings. POC detection of biomarkers and diagnostic adjuncts has emerged as non- or minimally invasive tools for the diagnosis of oral cancer at an early stage. Various biosensors have been developed for the rapid detection of oral cancer biomarkers at the point-of-care. Several optical imaging methods have also been employed as adjuncts to detect alterations in oral tissue indicative of malignancy. selleck This review summarizes the different POC platforms developed for the detection of oral cancer biomarkers, along with various POC imaging and cytological adjuncts that aid in oral cancer diagnosis, especially in low resource settings. Various immunosensors and nucleic acid biosensors developed to detect oral cancer biomarkers are summarized with examples. The different imaging methods used to detect oral tissue malignancy are also discussed herein. Additionally, the currently available commercial devices used as adjuncts in the POC detection of oral cancer are emphasized along with their characteristics. Finally, we discuss the limitations and challenges that persist in translating the developed POC techniques in the clinical settings for oral cancer diagnosis, along with future perspectives.The estimation of antenatal amniotic fluid (AF) volume (AFV) is important as it offers crucial information about fetal development, fetal well-being, and perinatal prognosis. However, AFV measurement is cumbersome and patient specific. Moreover, it is heavily sonographer-dependent, with measurement accuracy varying greatly depending on the sonographer's experience. Therefore, the development of accurate, robust, and adoptable methods to evaluate AFV is highly desirable. In this regard, automation is expected to reduce user-based variability and workload of sonographers. However, automating AFV measurement is very challenging, because accurate detection of AF pockets is difficult owing to various confusing factors, such as reverberation artifact, AF mimicking region and floating matter. Furthermore, AF pocket exhibits an unspecified variety of shapes and sizes, and ultrasound images often show missing or incomplete structural boundaries. To overcome the abovementioned difficulties, we develop a hierarchical deep-learning-based method, which consider clinicians' anatomical-knowledge-based approaches. The key step is the segmentation of the AF pocket using our proposed deep learning network, AF-net. link= selleck AF-net is a variation of U-net combined with three complementary concepts - atrous convolution, multi-scale side-input layer, and side-output layer. link2 The experimental results demonstrate that the proposed method provides a measurement of the amniotic fluid index (AFI) that is as robust and precise as the results from clinicians. The proposed method achieved a Dice similarity of 0.877±0.086 for AF segmentation and achieved a mean absolute error of 2.666±2.986 and mean relative error of 0.018±0.023 for AFI value. To the best of our knowledge, our method, for the first time, provides an automated measurement of AFI.
The purpose of this study was to examine whether curcumin, a turmeric root extract, protects human gingival epithelial (HGE) cells from the cytotoxic effects ofPorphyromonas gingivalis outer membrane vesicles (OMVs).

OMVs were prepared fromP. gingivalis OMZ314 and used to stimulate human gingival epithelial (HGE) cells. The effects of curcumin on cellular expression of inflammatory cytokines were evaluated using real-time reverse transcription-polymerase chain reaction assays, while those on cellular migration were examined with a scratch wound assay. Furthermore, HGE cells were incubated with OMVs in the presence or absence of curcumin, then intracellular invasion by OMVs was observed with confocal laser scanning microscopy. link2 Also, the effects of curcumin on cellular apoptotic death was examined.

Gene expressions of IL-6, IL-1β, and TNF-α in HGE cells stimulated with OMVs were significantly suppressed by curcumin in a dose-dependent manner, with suppressed protein production also noted. Moreover, curcumin inhibited the cytotoxic effects of OMVs on cellular migration. Finally, curcumin inhibited OMV adherence to and entry of cells, as well as cellular apoptotic death in a dose-dependent manner.

Curcumin showed marked inhibitory effects against the cytotoxic actions of P. gingivalis OMVs, indicating possible potency for preventing periodontal disease.

Wide individual variation observed in tooth agenesis patterns in patients with non-syndromic oligodontia could be affected by sexual dimorphism. Therefore, the present study investigated sex-associated differences in tooth agenesis patterns in patients with non-syndromic oligodontia.

Subjects were 108 male (ages 7-46 years) and 184 female (ages 7-43 years) orthodontic patients missing ≥6 permanent teeth, excluding third molars. The number of agenetic teeth per patient, excluding third molars, and the prevalence of agenesis of each tooth type were evaluated using panoramic radiographic images. Rankings of the most common tooth agenesis patterns in the maxillary and mandibular arches were calculated. The number of agenetic teeth per patient was compared between sexes using the Mann-Whitney test. The prevalence of tooth agenesis for each tooth type was compared between sexes using the χ
and Fisher's exact tests with Bonferroni correction.

No significant sex difference in the distribution of the number of utilized in future epidemiologic research and planning.
The aim of this study was to test the validity of a previously proposed lateral angle (LA) method for sex assessment of human skeletal remains in the forensic setting.

Computed tomography (CT) scans of 102 crania of Greek adults were used to test the validity of the LA method for sex estimation. The measurement procedure used in this study is a modified version of a method previously proposed by Akansel et al. (2008).

Despite the LA values being larger for females, the difference was not found to be statistically significant. Sectioning point of 45° provided a low accuracy rate of 53 %.

The poor accuracy of the LA method obtained in this study proved it to be of no value in sex estimation. Future studies should examine a broader aspect of the petrous portion morphology in order to establish a more accurate method of forensic sex estimation.

Plasma from PE patients increased ARE activity in endothelial cells compared with plasma from healthy pregnant (HP), and the addition of resveratrol was able to potentiate this increase only in PE. Resveratrol also decreased ROS levels in the cells incubated with plasma from PE. Based on these results, we performed a pilot clinical study to compare the effects of serum from PE women before and 1 h after ingestion of polyphenol-rich whole red grapefruit juice incubated on endothelial cells, since grapefruit contains large amounts of resveratrol. Serum from PE patients, obtained one hour after juice intake, decreased antioxidants markers in cells compared with the serum before juice intake, besides, it increased NO production. In conclusion, resveratrol and polyphenol-rich red grape juice have potentially beneficial effects on endothelial cells incubated with PE plasma/serum, which could aid in the management of PE.
Hypertensive pregnancy is associated with increased long-term cardiometabolic disease risk. Assessing dietary intake patterns after hypertensive (HP) versus normotensive pregnancy (NP) may provide insights into the mechanism of this risk.

This study was a prospective sub-study of the P4 (Postpartum, Physiology, Psychology and Paediatrics) cohort. Women were studied six months after NP versus HP (preeclampsia or gestational hypertension). Dietary energy, macronutrient and micronutrient intake were measured using a three-day food diary (FoodWorks™) and assessed against Australian and New Zealand Nutrient Reference Values to determine nutritional adequacy. Comparisons between breastfeeding and non-breastfeeding women were assessed, and linear regression modelling (using hypertensive status, breastfeeding status, and demographic/pregnancy variables) performed to assess predictors of energy intake.

Seventy-four women (60 NP, 14 HP) were included. HP women had higher mean body mass index (p=0.02) and lower breastfeeding rates (29% HP versus 83% NP, p<0.
