The current standard for treating pilonidal sinus (PNS) is surgical intervention with excision of the sinus. Recurrence of PNS can be controlled with good hygiene and regular shaving of the natal cleft, laser treatment is a useful adjunct to prevent recurrence. Carbon dioxide (CO2) laser is a gold standard of soft tissue surgical laser due to its wavelength (10600 nm) thin depth (0.03mm) and collateral thermal zone (150mic).It effectively seals blood vessels, lymphatic, and nerve endings, Moreover wound is rendered sterile by effect of laser. Aim of this study was to apply and assess the clinical usefulness of CO2 10600nm laser in pilonidal sinus excision and decrease chance of recurrence. Design: For 10 patients, between 18 and 39 year

Two aluminum plates were fixed inside the reactor and present two functions; first it works as split plates for internal loop generation of the airlift system (the zone between the two plates acts as riser while the other two zones act as downcomer) and second it works as two electrodes for electrocoagulation process. Simulated wastewater contaminated with zinc ions was used to test the performance of this apparatus for zinc removal by studying the effect of different experimental variables such as initial concentration of zinc (50-800 ppm), electrical current density (2.67-21.4 mA/cm2), init

Management of water resources in Vertisols is more problematic compared to other soil groups. This soil is representing a vast crop production resource and account for a considerable portion of the region under study. The preferential flow has a profound effect on the performance furrow irrigation in cracked soils.

This study aimed to evaluate the effectiveness of coconut shell-derived biochar supplementation in Murashige and Skoog (MS) medium to suppress contamination and enhance regeneration efficiency. A Completely Randomized Design (CRD) with 11 biochar concentrations (0–5 g/L) was used, each with three replicates. Parameters observed included contamination and browning onset, browning intensity, propagule formation time, fresh weight, shoot number, and shoot height. Results showed that biochar significantly delayed contamination and browning. The 2 g/L treatment yielded the best results: 13.8 days after culture (DAC) for contamination and 12.67 DAC for browning. The lowest browning intensity (score 1.41) occurred at 5 g/L. Propagule

The results revealed highly significant differences (P ≤ 0.01) in the number and frequency of the LEI0234 marker among the different alleles, with the A1 allele showing superior performance compared to the other alleles. The A1 allele appeared in various genotypic forms, with a frequency of 27.00%. No significant differences were observed among the alleles in terms of body weight, age at sexual maturity, egg mass, or feed conversion efficiency. However, significant differences (P ≤ 0.05) were recorded during the 8

The study divided 56 common carp into four treatment groups and fed diets containing different levels of fish oil over 56 days. Results showed significant differences in growth performance and feed efficiency between the treatments. The T3 (1.5% fish oil) and T4 (2% fish oil) groups showed the highest weight gain and most efficient feed conversion ratio, suggesting that 1.5% fish oil may support growth outcomes like those with 2% fish oil. Body composition analyses revealed favorable protein-to-fat ratios, suggesting improved nutrient retention and lean growth with reduced fish oil levels.
