Mutations involving isocitrate dehydrogenase 1 (IDH 1) occur in a high proportion of diffuse gliomas, with implications on diagnosis and prognosis. About 90% involve exon 4 at codon 132, replacing amino acid arginine histidine (R132H). Rarer ones include R132C, R132S, R132G, R132L, R132V, R132P. Most authors have used DNA-based methods to assess IDH1 status. Preliminary studies comparing imunohistochemistry (IHC) IDH1-R132H mutation-specific antibodies shown concordance DNA sequencing no...

Video tokenizers are essential for latent video diffusion models, converting raw data into spatiotemporally compressed spaces efficient training. However, extending state-of-the-art to achieve a temporal compression ratio beyond 4x without increasing channel capacity poses significant challenges. In this work, we propose an alternative approach enhance compression. We find that the reconstruction quality of temporally subsampled videos from low-compression encoder surpasses high-compression...

Melioidosis, caused by Burkholderia pseudomallei, is an emerging disease in Odisha, a state eastern coastal India. Difficult to diagnose, the likely be severely underreported. Seroprevalence studies general population are deemed necessary for estimate of melioidosis endemicity and explore associated risk factors. A population-based cross-sectional seroprevalence study was conducted using Indirect Hemagglutination Assay (IHA) among 1920 participants aged 5-60 years residing six out thirty...
