Noncoordinating Anions as Key Modulators of Supramolecular Structures, Optical and Electrical Properties in Nickel(II) Complexes.

This study explores the synthesis, structural characterization, and examination of two nickel(II) complexes, [Ni( )](NO) (complex ) and [Ni( )](ClO) (complex ), using the newly synthesized organic heterocyclic chelating ligand [4-imidazole-2,6-di(pyrazinyl)pyridine]. Through single-crystal X-ray diffraction, we have detailed the crystal structures of these complexes, highlighting their distorted octahedral geometries and diverse supramolecular interactions including π···π stacking, anion···π, and hydrogen bonding. These interactions crucially influence the formation of distinct one- and two-dimensional supramolecular architectures.

Canine umbilical cord tissue derived mesenchymal stem cells naturally express mRNAs of some antimicrobial peptides.

Antimicrobial peptides (AMPs) are naturally produced by all living organisms at a constitutive rate. They represent the first line of active defence systems against invading microorganisms, helping in innate immunity. Besides their therapeutic applications, great attention has also been given to the mesenchymal stem cells (MSCs) due to their antimicrobial activities.

Characterization of interferon gamma gene in relation to immunological responses in Haemonchus contortus resistant and susceptible Garole sheep.

Garole sheep exhibits within-breed difference in resistance to natural gastrointestinal nematode infection predominated by Haemonchus contortus.

Thin films of functionalized carbon nanotubes support long-term maintenance and cardio-neuronal differentiation of canine induced pluripotent stem cells.

Induced pluripotent stem cells (iPSCs) are a promising cell source for regenerative medicine. However, their feeder-free maintenance in undifferentiated states remains challenging. In recent past extensive studies have been directed using pristine or functionalized carbon nanotube in tissue engineering.

RFamide peptides, the novel regulators of mammalian HPG axis: A review.

The RFamide-related peptides (RFRPs) are the group of neuropeptides synthesized predominantly from the hypothalamus that negatively affects the hypothalamo-hypophyseal-gonadal (hypothalamic-pituitary-gonadal [HPG]) axis. These peptides are first identified in quail brains and emerged as the mammalian orthologs of avian gonadotropin inhibitory hormones. The RFRP-3 neurons in the hypothalamus are present in several mammalian species.

In vitro propagation and cardiac differentiation of canine induced pluripotent stem cells on carbon nanotube substrates.

Induced pluripotent stem cells (iPSCs) have attracted an interest for personalized cell based therapy along with various other applications. There have been few studies that effective nanomaterial based scaffolds act as alternative to the commonly used feeder dependent in vitro maintenance of iPSCs. The present study provides the fundamental information on ex vivo behavior of canine iPSC (ciPSCs) maintained on carboxylic acid (COOH) functionalized single-walled carbon nanotubes (COOH-SWCNTs) and multi-walled carbon nanotubes (COOH-MWCNTs) substrates.

Post-calving umbilical cord tissue offcut: A potential source for the isolation of bovine mesenchymal stem cells.

Preparation of NGF encapsulated chitosan nanoparticles and its evaluation on neuronal differentiation potentiality of canine mesenchymal stem cells.

Sustained and controlled release of neurotrophic factors in target tissue through nanomaterial based delivery system could be a better strategy for nerve tissue regeneration. The present study aims to prepare the nerve growth factor (NGF) encapsulated chitosan nanoparticles (NGF-CNPs) and its evaluation on neuronal differentiation potentiality of canine bone marrow derived mesenchymal stem cells (cBM-MSCs). The NGF-CNPs were prepared by ionotropic gelation method with tripolyphosphate (TPP) as an ionic cross-linking agent.

Functionalized carbon nanotubes as suitable scaffold materials for proliferation and differentiation of canine mesenchymal stem cells.

In the field of regenerative medicine, numerous potential applications of mesenchymal stem cells (MSCs) can be envisaged, due to their ability to differentiate into a range of tissues on the basis of the substrate on which they grow. With the advances in nanotechnology, carbon nanotubes (CNTs) have been widely explored for use as cell culture substrate in tissue engineering applications. In this study, canine bone marrow-derived MSCs were considered as the cellular model for an in vitro study to elucidate the collective cellular processes, using three different varieties of thin films of functionalized carbon nanotubes (COOH-single-walled CNTs [SWCNTs], COOH-multiwalled CNTs [MWCNTs] and polyethylene glycol [PEG]-SWCNTs), which were spray dried onto preheated cover slips.

Proliferation of canine bone marrow derived mesenchymal stem cells on different nanomaterial based thin film scaffolds.

Stem cell niche research uses nanotechnologies to mimic the extra-cellular microenvironment to promote proliferation and differentiation. The aim of designing different scaffolds is to simulate the best structural and environmental pattern for extracellular matrix. This experiment was designed to study the proliferative behaviour of canine bone marrow deriver mesenchymal stem cells (MSCs) on different nanomaterial based thin film scaffolds of carbon nanotubes (CNT), chitosan and poly ε-caprolactone.

Antigenic Cross-reactivity among of Goat.

Background: Cross antigenicity is the major problem in developing a reliable tool for immunodiagnosis and immunoprophylaxis of parasitic diseases. Mixed infection due to different types of gastrointestinal parasites is more common than single species infection under field condition.

Valproic acid assisted reprogramming of fibroblasts for generation of pluripotent stem cells in buffalo (Bubalus bubalis).

Generation of pluripotent stem cells by reprogramming somatic cells of quality animals has numerous potential applications in agricultural and biomedical sciences. Unfortunately, till now, reprogramming of buffalo fetal fibroblast cells (bFFs) has been very ineffient despite intensive efforts. Here, we attempted to enhance reprogramming efficiency by using the HDAC inhibitor valproic acid (VPA) in bFFs transfected with pLentG-KOSM pseudo virus carrying mouse specific pluripotent genes.

Isolation and characterization of mesenchymal stem cells from caprine umbilical cord tissue matrix.

Cord tissue fills the umbilical cord around the blood vessels and contains types of stem cells (mesenchymal stem cells or MSCs) that are not generally found in cord blood. MSCs are the stem cells that give rise to many of the "support tissues" in the body, including bone, cartilage, fat and muscle. Umbilical Cord Tissue cells (UCTs) possessing the capacity to differentiate into various cell types such as osteoblasts, chondrocytes and adipocytes have been previously isolated from different species including human, canine, murine, avian species etc.

On the Importance of Noncovalent Carbon-Bonding Interactions in the Stabilization of a 1D Co(II) Polymeric Chain as a Precursor of a Novel 2D Coordination Polymer.

A new cobalt(II) coordination polymer 2 with μ1,5 dicyanamide (dca) and a bidentate ligand 3,5-dimethyl-1-(2'-pyridyl)pyrazole (pypz) is prepared in a stepwise manner using the newly synthesized one-dimensional linear Co(II) coordination polymer 1 as a precursor. The structural and thermal characterizations elucidate that the more stable complex 2 shows a two-dimensional layer structural feature. Here, Co(II) atoms with μ1,5 dicyanamido bridges are linked by the ligand pypz forming a macrocyclic chain that runs along the crystallographic 'c' axis having 'sql' (Shubnikov notation) net topology with a 4-connected uninodal node having point symbol {4(4).
