This study examined the concentrations of seven heavy metals (Pb, Cu, Zn, Cr, Cd, Ni, and Mn) in the muscle tissue of six commonly consumed fish species (, , and ) from the River Indus in the Mianwali district Pakistan. Samples were collected during both pre-monsoon and post-monsoon seasons to assess the potential human health risks associated with these heavy metals. The levels of metals were measured using atomic absorption spectroscopic analysis.

- The study examined pesticide residues in water, sediment, and fish from the Indus River in Mianwali, Pakistan, across three sampling sites during dry and wet seasons.
- Elevated pesticide levels were found, with maximum concentrations noted in dry conditions, particularly for cypermethrin and carbofuran in water and endosulfan in fish, often exceeding safety limits.
- Results indicated significant health risks due to high Hazard Index values, emphasizing the need for improved agricultural practices and stricter pesticide regulations to protect aquatic ecosystems and food safety.
Accessory Cardiac Conduction Pathway with an Unusual Presentation.

Pre-excitation syndrome (PES) is a congenital abnormality in which there is conduction through accessory pathway in addition to atrioventricular (AV) node between the atria and the ventricles. Conduction through accessory pathway is without any delay and; hence, results in early excitation of ventricles. This dual connection provides substrate for atrioventricular reciprocating tachycardia (AVRT), a type of supra-ventricular tachycardia.
