Survival of a surrogate African swine fever virus-like algal virus in feed matrices using a 23-day commercial United States truck transport model.

African swine fever virus (ASFV) is a member of the nucleocytoplasmic large DNA viruses (NCLDVs) and is stable in a variety of environments, including animal feed ingredients as shown in previous laboratory experiments and simulations. virus (EhV) is another member of the NCLDVs, which has a restricted host range limited to a species of marine algae called . This algal NCLDV has many similar morphological and physical characteristics to ASFV thereby making it a safe surrogate, with results that are applicable to ASFV and suitable for use in real-world experiments.

Evaluating the effect of temperature on viral survival in plant-based feed during storage.

Viruses of veterinary significance are known to survive for extended periods in plant-based feed ingredients imported into North America. To reduce the likelihood of virus introduction, high-risk ingredients, such as oil seed meals, are stored in designated facilities for extended periods under controlled environmental conditions to minimize viral infectivity prior to use in diets. While 30 days has become a standard storage period, the required ambient temperature to inactivate viruses during this time is not known.

Evidence of viral survival in representative volumes of feed and feed ingredients during long-distance commercial transport across the continental United States.

The hypothesis that feed ingredients could serve as vehicles for the transport and transmission of viral pathogens was first validated under laboratory conditions. To bridge the gap from the laboratory to the field, this current project tested whether three significant viruses of swine could survive in feed ingredients during long-distance commercial transport across the continental US. One-metric tonne totes of soybean meal (organic and conventional) and complete feed were spiked with a 10 ml mixture of PRRSV 174, PEDV and SVA and transported for 23 days in a commercial semi-trailer truck, crossing 29 states, and 10,183 km.

Use of a demonstration project to evaluate viral survival in feed: Proof of concept.

In 2014, the hypothesis that feed ingredients could serve as vehicles for the transport and transmission of viral pathogens was proposed and evaluated by multiple investigators under laboratory conditions. In an attempt to validate these data, we used a demonstration project to test whether three significant viruses of swine could survive in feed ingredients under real-world shipping conditions. Samples of soya bean meal (organic and conventional), lysine, choline and vitamin A were spiked with a mixture of PRRSV 174, PEDV and SVA and transported for 21 days in the trailer of a commercial transport vehicle, encompassing 14 states and 9,741 km.

Human Thelaziasis: Emerging Ocular Pathogen in Nepal.

Thelaziasis is an ocular arthropod-borne, zoonotic disease of the eye infecting the conjunctival sac, lacrimal duct, and lacrimal gland caused by a nematode of the genus . We report the first case of human ocular thelaziasis in Nepal in a 6-month-old child from a Rukum district, Nepal. The infant presented with conjunctivitis, and his visual acuity and dilated fundal examination were normal.

A multicenter prospective study of infections related morbidity and mortality in cirrhosis of liver.

Background And Aims: Infections are a common and serious complication among patients with cirrhosis. We assessed the epidemiology, risk factors, and clinical consequences of bacterial infections in cirrhotic patients.

Methods: In this multicenter prospective study, all patients with cirrhosis of liver with different infections were analyzed.

Aerosol-assisted plasma deposition of hydrophobic polycations makes surfaces highly antimicrobial.

The currently used multistep chemical synthesis for making surfaces antimicrobial by attaching to them hydrophobic polycations is replaced herein by an aerosol-assisted plasma deposition procedure. To this end, N,N-hexyl,methyl-PEI (HMPEI) is directly plasma-coated onto a glass surface. The resultant immobilized HMPEI coating has been thoroughly characterized and shown to be robust, bactericidal against Escherichia coli, and virucidal against human influenza virus.

Bilateral maxillary brown tumours as the first presentation of primary hyperparathyroidism.

Introduction: Symptomatic skeletal disease in primary hyperparathyroidism is over 30 times more common in India compared to the west. The classical "brown tumour" is commonly seen with the major sites being ends of long bones, the pelvis and ribs. Facial involvement is rare and, when present, usually involves the mandible.

Nanostructured sorbents for capture of cadmium species in combustion environments.

The pathways of cadmium species to form a submicrometer-sized aerosol in a combustion system exhaust were established. Cadmium oxide was the predominant species formed in the experiments and resulted in particles of a mean size of 26-63 nm with number concentrations in the range of 2-8 x 10(6) cm(-3). Two different nanostructured sorbents, a solid montmorillonite (MMT) and an in situ generated agglomerated silica, were used for capture of the cadmium species.
