Sperm mitochondria are vital organelles for energy production and pre- and post-fertilization sperm functions. The potential influence of the age of the bull and season on the sperm-borne mitochondrial copy number and the transcription activity has not yet been investigated. Therefore, the expression patterns of all protein-coding mitochondrial genes were identified throughout the year along with mitochondrial copy numbers in young and old bulls' spermatozoa.

- Nuclear factor (erythroid-derived 2)-like 2 (NFE2L2) is a key protein involved in the cellular response to stress, and genetic variations (specifically in the GCC microsatellite) can affect its function in sperm cells.
- A study investigated the relationship between this genetic variation and sperm quality in young and old Holstein bulls across different seasons, using sequencing and mRNA analysis.
- Results indicated that certain GCC repeat variations were linked to different mRNA levels of antioxidant genes, with older bulls displaying higher expression of NFE2L2, especially during seasons with lower sperm quality.
Data on environmental contamination of the parasites of zoonotic importance is scarce in Pakistan. Soil contamination with feces of dogs hide infective stages of the parasite represents a health-risk to humans. This study was aimed to assess the eggs of gastrointestinal parasites of stray dogs and household dogs in lower Dir district, Pakistan with special consideration to those that can be spread to humans.
