Immunotherapeutics are gaining a post in the field of NENs in cases progressing during the course of the disease, dictating urgently the identification of biomarkers that will enable selection of NEN patients who may benefit from this treatment.

To determine agreement in keratometric readings obtained using rotating Scheimpflug imaging with Pentacam, biograph with Lenstar LS900, and Topcon KR-8100P auto-keratorefractometer in eyes with different stages of keratoconus.
A total of 89 eyes of 58 patients with keratoconus were examined in this study, retrospectively. The eyes were divided into two groups mild group (group 1 42 eyes) (Amsler-Krumeich stage 1) and moderate-to-severe group (group 2 47 eyes) (Amsler-Krumeich stage 2, 3, 4). The keratometric readings measured using the Pentacam Scheimpflug system, Lenstar LS900, and Topcon KR-8100P auto-keratorefractometer were compared between the groups. The effects of the measurements of anterior chamber depth, Q value, axial length, central corneal thickness (CCT), and maximum value of keratometry (Kmax) on the differences of devices for keratometric readings were investigated.
The mean values of the keratometric readings obtained using the Lenstar were steeper than with the Pentacam and Topcon, esp stages of keratoconus. The keratometric readings of Lenstar were found steeper than the other devices with increasing grades of keratoconus. None of these devices can be used interchangeably in moderate-to-severe stages of keratoconus.
To clarify the clinical features of uveitis in elderly patients in central Tokyo.
We retrospectively identified 1424 patients with uveitis who visited the Uveitis Clinic of the University of Tokyo Hospital between January 2013 and December 2018. The patients were categorized into two groups based on their ages at the time of disease onset patients aged 65years or older were included in Group A, whereas those younger than 65years were included in Group B. The etiological classification of uveitis and its causes were investigated for each group.
Group A presented significantly higher rates of infectious uveitis (35.5% vs. 17.8%, p < 0.0001) and masquerade syndromes (17.9% vs. 5.0%, p < 0.0001) than Group B. Furthermore, Group A had significantly higher rates of sarcoidosis (23.1% vs. 9.3%, p < 0.0001), intraocular lymphoma (16.6% vs. 4.6%, p < 0.0001), cytomegalovirus iritis (11.0% vs. 5.6%, p = 0.0043), and cytomegalovirus retinitis (5.2% vs. 1.5%, p = 0.0020) than Group B.
Our results demonstrate a clear difference in the causative diseases of uveitis between elderly and non-elderly patients. These findings may support ophthalmologists in their diagnostic process for elderly patients with uveitis.

Mercury content was studied in Bay Sivash (the Sea of Azov), the world's largest hypersaline lagoon with a strong salinity gradient from 36 to 90 g l-1. The dissolved mercury compounds ranged from 120 to 250 ng l-1, Hg varied from 60 to 450 ng l-1 in the suspended matter, and total mercury in the water ranged from 200 to 600 ng l-1. Salinity and the total suspended matter had practically no effect on the amount of dissolved and suspended forms of mercury separately, but their growth significantly increased total mercury content in water. Only the concentration of dissolved forms of mercury in water significantly correlated with dissolved organic matter. The Hg concentration in the bottom sediments averaged 13.8 ng g-1 wet weight. Both high salinity and human activities on the Sivash drainage area are responsible for high Hg content in lagoon water.Pollution of the atmosphere is known that may lead to adverse obstetric outcomes, including fetal growth restriction, gestational hypertension, and preeclampsia. Such disorders are correlated with imbalances in angiogenic factors, which may also be involved in the pathological mechanism as the pollutants impact placental and maternal physiology. In the first trimester of gestation, this study assessed the outcomes of personal maternal short period exposure to air pollution on soluble fms-like tyrosine kinase 1 (sFlt1) and placental growth factor (PLGF) of pregnant women blood concentrations. This was a cross-sectional study, held in the city of São Paulo, Brazil, and conducted with low-risk pregnant women, who carried personal passive nitrogen dioxide (NO2) and ozone (O3) monitors for about a few days preceding the ultrasound evaluation, and on this day, the venous blood sample was collected to measure the angiogenic factors sFlt1 and PLGF and their ratio (sFlt1/PLGF) by enzyme-linked immunosorbent assay (ELISA). By means of multiple regression models, the effect of the studied pollutants on the log-transformed concentrations of the angiogenic factors was evaluated. One hundred thirty-one patients were included. The log of the sFlt1/PLGF ratio increased with rising NO2 levels (p = 0.021 and beta = 0.206), and the log of the PLGF concentration showed a negative correlation with NO2 (p = 0.008 and beta = - 0.234). NO2, an indicator of the levels of primary air pollutants, presented significant positive correlation with an increased sFlt1/PLGF ratio and diminished PLGF levels, which may reflect an antiangiogenic state generated by air pollution exposure.Antibiotic resistance is a mushrooming pandemic at national and international levels which if not controlled at this very moment, can lead to global problems. Main reason for emerging bacterial resistance is repeated exposure of bacteria to antimicrobial agents and access of bacteria to increasingly large pools of antimicrobial resistance genes in mixed bacterial populations. A total of 51 villages were sampled in the current study contributing to a total of 153 farms. A total of 612 samples comprising 153 each of raw pooled milk samples, slurry, animal drinking water and human drinking water were gathered from small, medium and large farms located in all seven tehsils of Ludhiana district of Punjab. In addition to that, 37 samples of village pond water were also collected from the targeted villages. Out of total 153 slurry, raw pooled milk samples, animal drinking water and human drinking water samples (each), the prevalence of 24.8%, 60%, 26.7% and 16.3% was found for E. coli respectively. CC-90001 purchase On the other hand, for Klebsiella, the overall prevalence of 19.
