Histopathologic Observations of Eyes in Exenterated Orbits After Neoadjuvant Intra-Arterial Cytoreductive Chemotherapy for Adenoid Cystic Carcinoma of the Lacrimal Gland.

Purpose: To assess whether exenteration specimens obtained after neoadjuvant intra-arterial cytoreductive chemotherapy (IACC) for adenoid cystic carcinoma of the lacrimal gland demonstrate significant ocular histopathologic alterations that might preclude future pursuit of globe-preserving therapy.

Methods: Retrospective histopathologic analysis of globes in IACC-treated exenteration specimens among the same cohort of patients whose survival outcomes have been reported.

Results: Twenty patients had specimens available.

Impact of Heat Stress on Cellular and Transcriptional Adaptation of Mammary Epithelial Cells in Riverine Buffalo (Bubalus Bubalis).

The present study aims to identify the heat responsive genes and biological pathways in heat stressed buffalo mammary epithelial cells (MECs). The primary mammary epithelial cells of riverine buffalo were exposed to thermal stress at 42°C for one hour. The cells were subsequently allowed to recover at 37°C and harvested at different time intervals (30 min to 48 h) along with control samples (un-stressed).

Matrix-based three-dimensional culture of buffalo mammary epithelial cells showed higher induction of genes related to milk protein and fatty acid metabolism.

Demanding transcriptomic studies in livestock animal species could be replaced by good in vitro models mimicking the function of mammary gland. Mammary epithelial cells (MEC) are the functional unit of the mammary gland. Extracellular matrix is known to be a key factor providing normal homeostasis in three-dimensional (3D) environment as important signals are lost when cells are cultured in two-dimensional (2D) environment.

Peripheral blood mononuclear cells: a potential cellular system to understand differential heat shock response across native cattle (Bos indicus), exotic cattle (Bos taurus), and riverine buffaloes (Bubalus bubalis) of India.

Circulating leukocytes can be used as an effective model to understand the heat stress response of different cattle types and buffaloes. This investigation aimed to determine the temporal profile of HSPs (HSP40, HSP60, HSP70, and HSP90) expression in circulating peripheral blood mononuclear cells (PBMCs) of Murrah buffaloes, Holstein-Friesian (HF), and Sahiwal cows in response to sublethal heat shock at 42 °C. The viability data indicated HF PBMCs to be the most affected to the heat shock, whereas Sahiwal PBMCs were least affected, indicating its better survivability during the heat stress condition.

Selection of stable reference genes in heat stressed peripheral blood mononuclear cells of tropically adapted Indian cattle and buffaloes.

Eleven reference genes from different functional categories were assessed for their stable expression pattern in heat stressed PBMCs across Indian buffalo and cattle using GeNorm, NormFinder and BestKeeper algorithms. As the first report, we suggest B2M, RPS9 and RPS15a as suitable reference genes for accurate normalization of PBMC transcript data while the ACTB gene is not recommended.

Identification of Appropriate Reference Genes for qRT-PCR Analysis of Heat-Stressed Mammary Epithelial Cells in Riverine Buffaloes (Bubalus bubalis).

Gene expression studies require appropriate normalization methods for proper evaluation of reference genes. To date, not many studies have been reported on the identification of suitable reference genes in buffaloes. The present study was undertaken to determine the panel of suitable reference genes in heat-stressed buffalo mammary epithelial cells (MECs).

The role of N dopant in inducing ferromagnetism in (ZnO)n clusters (n = 1-16).

The effect of nitrogen doping on the magnetic properties of (ZnO)(n) clusters (n = 1-16) has been investigated using spin polarized density functional theory. The total energy calculations suggest that N is more stable at the O site than at the Zn site in (ZnO)(n) clusters and induces a magnetic moment of 1 μ(B)/N atom. The N-Zn-N configuration is more stable than isolated N for 3D structures.

Transition metal induced magnetism in smaller fullerenes (Cn for n≤36).

The magnetic properties of 3d transition metals (TM) encapsulated inside smaller fullerenes ranging from C20 to C36 have been investigated using spin polarized density functional theory. The TM impurities stabilize asymmetrically at an off-center position for n≥28. The total magnetic moment (MM) of TM@Cn complexes are largely contributed by TMs and a small amount of MM of 0.
