The Anti-Cancer Stem Cell Properties of Copper(II)-Terpyridine Complexes with Attached Salicylaldehyde Moieties.

We report the synthesis, characterisation, and anti-breast cancer stem cell (CSC) properties of two copper(II)-terpyridine complexes with bidentate salicylaldehyde moieties (2-hydroxybenzaldehyde for 1 and 2-hydroxy-1-naphthaldehyde for 2). The copper(II)-terpyridine complexes 1 and 2 are stable in biologically relevant aqueous solutions and display micromolar potency towards breast CSCs. The most effective complex 1 is 5-fold and 6.

Novel pathologic findings and viral antigen distribution in cattle and buffalo calves naturally infected with Foot-and-Mouth disease virus.

The Foot-and-Mouth disease is highly contagious acute viral disease of livestock inflicting huge economic loss to the farmers. The limited knowledge regarding the pathological lesions vis-a-vis distribution of the FMDV in lesser explored endocrine glands and important vital organs other than the target organs of infected calves prompted us to take the present investigation to have detailed insight into the pathogenesis. The systematic necropsy of 37 dead calves (cattle-28 and buffalo-9) was conducted, and thin representative tissue pieces from the affected organs were collected in 10% neutral buffered formalin (NBF) for pathological and immunohistochemical investigations.

AFB1 induced free radicals cause encephalopathy in goat kids via intrinsic pathway of apoptosis: pathological and immunohistochemical confirmation of non-hepatic neuroaflatoxicosis.

Aflatoxins, particularly AFB1, are the most common feed contaminants worldwide, causing significant economic losses to the livestock sector. The current paper describes an outbreak of aflatoxicosis in a herd of 160 male young goat kids (3-4 months), of which 68 young kids succumbed over a period of 25 days after showing neurological signs of abnormal gait, progressive paralysis and head pressing. The haematobiochemical investigation showed reduced haemoglobin, leucocyte count, PCV level, increased levels of AST, ALT, glucose, BUN, creatinine and reduced level of total protein.

Cancer stem cell activity of copper(II)-terpyridine complexes with aryl sulfonamide groups.

Copper(II)-terpyridine complexes are endowed with the ability to generate reactive oxygen species (ROS) and induce cancer cell death. Here we report the synthesis, characterisation, and anti-breast cancer stem cell (CSC) properties of a series of copper(II)-terpyridine complexes containing aryl sulfonamide groups (1-5). All of the copper(II)-terpyridine complexes adopt distorted square pyramidal geometries and are suitably stable in biologically relevant solutions (PBS and cell culture media).

Pathomorphology, immunohistochemical, and molecular detection of an atypical porcine dermatitis and nephropathy syndrome (PDNS) due to PCV-2d-2 in naturally affected grower pigs of India.

Porcine circovirus type 2 (PCV-2) is of great economic significance to porcine industry worldwide. PCV-2 variants and genotypes, alternating world over, are the etiological agent of several clinical syndromes such as porcine dermatitis and nephropathy syndrome (PDNS), post-weaning multi-systemic wasting syndrome (PMWS) and others in pigs. This study is reporting an atypical manifestation of PDNS in twelve grower pigs, 3- to - 4.

Novel pathological findings and immunohistochemical detection of FMDV antigens in the brain of calves naturally infected with foot-and-mouth disease.

Foot-and-mouth disease (FMD) is an extremely contagious and economically devastating viral disease of cloven-hoofed domestic and wildlife animals. The disease is endemic in India and other developing countries of the world. The disease is mainly characterized by the presence of vesicular lesions and "tigroid heart" in calves.

Localization of Pasteurella multocida antigens in the brains of pigs naturally infected with Pasteurellosis revealing a newer aspect of pathogenesis.

Pasteurella multocida is an economically important respiratory pathogen of pigs confronting swine industry worldwide. Despite extensive research over the decades, its pathogenesis is still poorly understood. Recent reports have demonstrated the nervous system affection as a newer aspect of pathogenesis by Pasteurella multocida type B:2 in Haemorrhagic Septicemia, but there are no reports of the involvement of nervous system by P.

Neuropathology mediated through caspase dependent extrinsic pathway in goat kids naturally infected with PPRV.

Peste des petits ruminant (PPR), a highly contagious viral disease of small ruminants, is characterized by erosive stomatitis and pneumo-enteritis. However, its neurovirulence potential as observed with other morbilliviruses has not been fully investigated. The present study describes the neuropathological alterations induced by PPR virus through apoptotic pathway.
