P63 is a gene product required in cell cycle regulation which plays vital roles in tumor differentiation. Aims of the present study were to assess the frequency, pattern, sensitivity and specificity of two p63 protein clones P63 4A4 and P63 4A4+Y4A3 in squamous cell carcinomas (SCCs). Thirty cases of head and neck region SCC diagnosed on the basis of H&E staining were examined along with 60 cases of head and neck region biopsies other than squamous cell carcinoma, negative on H&E staining, were taken as control. Immunostaining was performed on slides according to the Thermo Scientific UltraVision LP detection System. P63 4A4+Y4A3 clone is more sensitive 96.6% in comparison to 86% in P63 4A4 with having greater NPV of 98.3%. The results signify the importance of P63 4A4+Y4A3 marker over the old markers and may be used as a confirmatory marker of squamous cell carcinoma.

In the modern world of health and life sciences, the utilization of nanoscale materials, particularly magnetic nanoparticles, is a hot topic. Here in the present study, MgFe2O4 is synthesized via the chemical co-precipitation technique, and the polypyrrole (PPy) is fabricated via in situ polymerization technique to form the MgFe2O4/PPy nanocomposite by varying its content in the ferrite material. The electrical, magnetic, and dielectric properties of the fabricated materials were studied to investigate their applications in electronic devices. The magnetization saturation Ms, remanence Mr and coercivity Hc increase with the addition of ferrite material. The activation of the fabricated material increases from 0.11 to 0.34 eV, indicating the increase in electrical resistivity. The other important parameters such as squareness ratio and drift mobility were also calculated. The increment in DC electrical resistivity, saturation magnetic magnetization and remanence as well as reduction in dielectric constant values with the ferrite material addition in the polypyrrole suggest that the materials can be beneficial for recording media as well as high-frequency devices.

Yellowing disease of palms caused by phytoplasma is spreading in the Arabian Gulf region. Surveys were conducted to determine the occurrence of the disease. Electron and fluorescence microscopy, and polymerase chain reaction (PCR) techniques were used to detect the phytoplasma associated with the yellowing disease of ornamental palm Washingtonia sp. grown in Kuwait. An accumulation of phytoplasmal DNA was observed by fluorescence microscopy in phloem tissues of diseased palms. Electron microscopy showed that phytoplasma cells were primarily confined to the phloemsieve elements of tissue samples collected from infected mature palms in the field. The pathogen was identified on the basis of molecular analysis using universal and specific nested primers in PCR amplifications. Prokaryotic 16S rDNA gene was detected in amplified PCR products. Nested PCR resulted in DNA amplification of 1.2 kbp fragment. This is the first report of a phytoplasmal rDNA gene identified from the putative causal pathogen of yellows in ornamental palms in the Arabian Gulf region.

Manganese ferrite offers several advantages when employed as an electrocatalytic material for supercapacitors, including outstanding cycle stability and energy capacity. When compared to identical-metal sulfides, specific capacitance (Csp) of MnFe2O4 remains inadequate. So, using the hydrothermal synthesis technique, partial sulfur doping of MnFe2O4 was achieved to investigate the synergetic effect of oxides and sulfides. Various spectroscopic and microscopic studies demonstrate that adding sulfur atoms into MnFe2O4 increases the lattice parameters, which improves electrochemical performance. At a current density around 2 A g−1, then calculating MnFe2O4 with partial sulfur doping has a Csp of 1,201.60 F g−1, that is greater than 784.0 F g−1 of pure MnFe2O4. Maximum energy density (Ed) of 93.62 Wh kg−1 was produced with a power density (Pd) of 749 W kg−1. The current study depicts that partial sulfur doping can enhance the electrochemical behavior of MnFe2O4. As a result, the present work shows more effective in field of energy storage by enhancing their poor electrochemical performance.
