ABSTRACT
Spider species are important for maintaining ecological balance, controlling insect populations, and providing potential sources of medicinal compounds. Highlighting the importance of spider species, the present study was aimed at exploring the diversity of spider fauna and species richness in various habitats in District Mardan, Khyber Pakhtunkhwa, Pakistan, from March 2021 to December 2021. Spiders were collected through different methods: pitfall traps, cryptic searching, ground hand collection, aerial hand collection, and vegetation beating. Then, the captured spiders were washed in alcohol and preserved in a combination of 80% alcohol and 20% glycerol for further observation. Identification was carried out with the help of available spider identification keys and literature. A total of 578 specimens representing 29 species from 17 families and 26 genera were collected and identified. Family Lycosidae was the most dominant family (13.49%), followed by Salticidae (10.2%), Araneidae (8.47%), Tetragnathidae (7.61%), Pholicidae (6.4%), Oxyopidae (5.88%), Thomisidae (5.7%), Clubionidae (5.53%), Sicariidae (5.19%), Scytodidae (5.01%), Corinnidae (4.67%), Agelenidae (4.32%), Cheiracanthiidae and Sparassidae (4.15%), Oecobiidae and Hersiliidae (3.97%) and Theridiidae was the rarest among all (1.21%). The most commonly identified species are Hippasa partita, Lycosa poonaesis, Lycosa terrestris, Draposa oakleyi, Plexippus paykulli, Menemerus nigli, Thyene imperialis, Thyene bivittate and Hasarius adansoni. Argiope versicolor, Neoscona theisi, Tetragnatha extensa, Crossopriza lyoni, and Oxyopes Javanus. During the present study, it was observed that spider species were abundantly found in warm areas from May to August, which demonstrates that the spider fauna of the study area is very rich but has yet to be explored.

This case report puts an emphasis on retaining and re-fixing any avulsed bony segments in the maxillofacial region and maintaining the periosteal layer whenever possible, especially in young patients. Adequate bony fixation and watertight soft tissue closure are vital components for bone healing. The healing potential of facial bones is much higher as compared to the long bones, due to the superior blood supply.

The changing pattern in hepatitis C virus (HCV) clades overtime is not well known in Pakistan. To find out the changing pattern of different HCV clades over time in this country 22,125 patients were genotyped and tracked for a period of 11 years (2000-2010). A changing pattern in HCV clades was seen in this region during the study period. Sub-clade 3a remained the dominant sub-clade circulating in different areas of the country in the study era. HCV sub-clade 3a demonstrated significantly high correlation with time (p < 0.05) whereas undetermined clades were seen with statistically non-significant correlation with time (years). All the other clades showed negative correlation with time. In general a significant decline was observed in the percentages of HCV clades 2, 4, 5 and 6 (p < 0.001). Among sub-clades, HCV 1a, 2c, 2b and 3b significantly decreased overtime (p < 0.05), while an increase has been observed for HCV 3a sub-clade and mixed clades (p <0.001). The ratio of undetermined clades remained constant over the study period. In conclusion, a changing pattern of HCV clades was observed over the 11-year study period, and this changed pattern might have direct impact on HCV disease outcome.
