From 2013 to 2015, the National Institute of Health, Pakistan, received 1,270 blood samples of suspected dengue cases reported from inpatient and outpatient departments of various hospitals in Khyber Pakhtunkhwa (KPK) province. In this study, we determined the circulating dengue virus (DENV) serotypes using real-time reverse transcriptase (RT)-PCR to understand the serotype-based epidemiology of DENV. All four serotypes (DENV-1 [6%], DENV-2 [33%], DENV-3 [47%], and DENV-4 [0.1%]) were found circulating during the study period. Our findings suggest the need for an active surveillance system coupled with the laboratory diagnosis, especially in the chronic endemic areas of the country. Public awareness programs are needed for effective control and prevention of outbreaks in the future.

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.

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.
