INTRODUCTION: Cancer is a leading cause of death worldwide and is a major cause of morbidity. To deal with this magnitude of cancers and their diagnostic and prognostics, a multitude of prognostic biomarkers for various cancers have been explored over the decades, with detection of circulating tumor cells (CTCs) in the peripheral blood being one of them. This study was undertaken to explore the routine procedure of cell block in the cytopathology lab to isolate and detect CTCs. MATERIALS AND METHODS: In this cross-sectional study, 112 peripheral blood samples sent for routine blood investigations of various cancer patients were utilized for the preparation of cell block...

Delayed presentation of lower cervical facet dislocations is uncommon, and there is no standardized way to approach these neglected injuries. The literature on neglected lower cervical facet dislocations is limited to case reports and few retrospective studies. This justifies the need for a comprehensive review of this condition. Our purpose was to elaborate a review on the epidemiology, clinical and radiological presentation, and treatment techniques and approach to these neglected injuries. Middle-aged adults from 30 to 50 represent 73...

BACKGROUND: Polychlorinated alkanes (PCAs) constitute a large group of individual congeners originating from commercial chlorinated paraffin (CP) products with carbon chain lengths of PCAs-C10-13 , PCAs-C14-17 , and PCAs-C18-32 , occasionally containing PCAs-C6-9 impurities. The extensive use of CPs has led to global environmental pollution of PCAs. This study aimed to quantify PCAs in paired serum and breast milk of lactating Swedish mothers, exploring their concentration relationship...

Extended conjugated polyynes provide models for the elusive sp carbon polymer carbyne, but progress has been hampered by numerous synthetic challenges. Stabilities appear to be enhanced by bulky, electropositive transition-metal endgroups. Reactions of trans -(C6 F5 )( p -tol3 P)2 Pt(C≡C) n SiEt3 ( n = 4-6, PtC x Si ( x = 2 n )) with n -Bu4 N+ F- /Me3 SiCl followed by excess tetrayne H(C≡C)4 SiEt3 ( HC 8 Si ) and then CuCl/TMEDA and O2 give the heterocoupling products PtC x +8 Si , PtC x +16 Si , and sometimes higher homologues...

OBJECTIVE: Common complications after spinal fusion, such as pseudoarthrosis, cage subsidence, or instrumentation failure, are affected by patients' bone quality. The cervical-vertebral bone quality (C-VBQ) score, a magnetic resonance imaging-based adaption of the lumbar vertebral bone quality (VBQ) score, was developed by three separate research groups simultaneously to evaluate bone quality in cervical spinal fusion patients. We present the first analysis comparing these scoring methods to the well-validated VBQ score...

Rift Valley fever virus (RVFV) is a mosquito-borne zoonotic pathogen causing disease in livestock and humans. Whilst initially restricted to the African continent, recent spread to the Arabian Peninsula has highlighted the likelihood of entry into new regions. Due to the absence of a regulatory-approved human vaccine, work is ongoing to develop and assess countermeasures. As such, small animal models play a pivotal role in providing information on disease pathogenesis and elucidating which intervention strategies confer protection...

Advances in sequencing technologies and bioinformatics have greatly enhanced our knowledge of virus biodiversity. Currently, the viromes of hematophagous invertebrates, such as mosquitoes and ixodid ticks, are being actively studied. Tabanidae (Diptera) are a widespread family, with members mostly known for their persistent hematophagous behavior. They transmit viral, bacterial, and other pathogens, both biologically and mechanically. However, tabanid viromes remain severely understudied. In this study, we used high-throughput sequencing to describe the viromes of several species in the Hybomitra , Tabanus , Chrysops , and Haematopota genera, which were collected in two distant parts of Russia: the Primorye Territory and Ryazan Region...

OBJECTIVE: Dengue viruses (DENV) and Zika viruses (ZIKV) are transmitted from human to human or from non-human primates to humans by mosquito biting, so the viral interaction with mosquito cells is one key step within the viral life cycle. Therefore, our objective is to know how DENV or ZIKV interacts with mosquito cells. METHODS: Immunofluorescence assay and a direct visualization system are combined to monitor the syncytial or congregative effects of DENVs and ZIKVs on C6/36 cells...

AIM: Increasing trend for progression-free survival (PFS)-based primary endpoint in oncology has led to lack of mature overall survival (OS) data at the time of approval. To address this evidence gap in economic evaluations, we used a joint Bayesian approach to predict survival outcomes using immature OS data from the RELAY trial. METHODS: Patient data from RELAY and systematic literature review (SLR) of phase 3 randomized clinical trials with hazard ratio (HR) estimates of mature PFS and immature OS were considered...

INTRODUCTION: Banna virus (BAV), a potential pathogen that may cause human encephalitis, is the prototype species of genus Seadornaviru within the family Reoviridae , and has been isolated from a variety of blood-sucking insects and mammals in Asia. METHODS: Culicoides , Mosquitoes , and Ticks were collected overnight in Yunnan, China, during 2016-2023 using light traps. Virus was isolated from these collected blood-sucking insects and grown using Aedes albopictus (C6/36) cells...

UNLABELLED: Alphaviruses infect both mammals and insects, yet the distinct mechanisms that alphaviruses use to infect different hosts are not well defined. In this study, we characterize CHIKV E1 variants in the fusion loop (E1-M88L) and hinge region (E1-N20Y) in vitro and in vivo to understand how these regions of the E1 glycoprotein contribute to host-specific infection. Through cell culture assays, we found that CHIKV E1-N20Y enhanced infectivity in mosquito cells while the CHIKV E1-M88L variant enhanced virus binding and infectivity in both BHK-21 and C6/36 cells, and led to changes in the virus cholesterol-dependence in BHK-21 cells...

These grading scales have not previously been validated in a cohort of patients awaiting surgery. OBJECTIVES: To establish the normal foraminal and root diameters as well as the consistency of inter and intra-rater grading using the Kim and modified Kim grading systems in pre-operative surgical patients. METHODS: Asymptomatic cervical nerve roots and foramina demonstrated on the pre-operative MRI scans of adult surgical patients with cervical radiculopathy were measured and categorised by six raters using the Kim and modified Kim grading methods...

PURPOSE: To investigate the connection between the clinical severity of chronic venous insufficiency (CVI) and the biomechanics of the calf muscle pump (CMP). MATERIAL AND METHODS: Through a cross-sectional observational study, we analyzed women on the age range between 30 and 80 years with chronic venous insufficiency, stratified according to the clinical classification. Ninety-nine women were assessed and classified into groups with different levels of severity: C1 (n = 22); C2 (n = 22); C3 (n = 22); C4 (n = 22); C5 (n = 8); C6 (n = 3)...

Yokose virus (YOKV) is a bat-associated no-known vector flavivirus group member. We investigated the replication ability of YOKV in mosquito-derived C6/36 cells. YOKV grew in C6/36 cells, but its kinetics of YOKV was markedly slower than those of other mosquito-borne flaviviruses. Transmission electron microscopy indicated an extremely small number of viral particles in YOKV-infected C6/36 cells. Mosquito-borne Japanese encephalitis virus prM-E-bearing chimeric YOKV failed to propagate efficiently in C6/36 cells...

Surveillance of mosquito vectors is critical for early detection, prevention and control of vector borne diseases. In this study we used advanced molecular tools, such as DNA barcoding in combination with novel sequencing technologies to discover new and already known viruses in genetically identified mosquito species. Mosquitoes were captured using BG sentinel traps in Western Kenya during May and July 2019, and homogenized individually before pooled into groups of ten mosquitoes. The pools and individual samples were then used for molecular analysis and to infect cell cultures...

Recent studies have reported increased levels of urea in the aging brain and various neurological disorders. Additionally, these diseased tissues also have increased expression of the UT-B transporter that regulates urea transport in the brain. However, little is known regarding the actual UT-B protein distribution across the brain in either normal or diseased states. This current study investigated UT-B protein abundance across three regions of the rat brain - anterior, posterior and cerebellum. Endpoint RT-PCR experiments showed that there were no regional differences in UT-B RNA expression (NS, N = 3, ANOVA), whilst Western blotting confirmed no difference in the abundance of a 35 kDa UT-B protein (NS, N = 3-4, ANOVA)...
