Effect of honey dressing material on palatal wound healing after harvesting a free gingival graft: a prospective randomized case control study.

OBJECTIVE: The aim of this prospective randomized case-control study was to understand the clinical benefits and effect of honey as a dressing material on palatal wound healing after harvesting free gingival graft (FGG). PATIENTS AND METHODS: This prospective randomized case-control study was conducted on a sample of 20 patients with 10 patients in each group. Medihoney dressing material was applied to the donor site in the test group, whereas no dressing material was applied to the control group. All the patients received the same medication (Ibuprofen 600 mg) and post-operative instructions straight away after the surgical procedure. Patients were given the follow-up appointment at first, second and fourth week after the surgery during which the length and the width of the donor site was measured and recorded. RESULTS: At first week, a significant difference in the proportion of patients showing the healing of donor site percentage was found to be 56% (both in width and length) for test group vs. 44% (both in width and length) for the control group (p=0.001). At 4-week, the healing of donor site percentage was found to be 86% (in width) and 91% (in length) for test group vs. 14% (in width) and 9% (in length) for the control group, the difference being statistically significant (p=0.001). CONCLUSIONS: The result of this current study suggests that the honey dressing material accelerated the wound healing process of the palatal wound after harvesting FGG. It also showed a shorter recovery period along with less post-operative morbidity.

In silico characterization, docking, and simulations to understand host-pathogen interactions in an effort to enhance crop production in date palms.

Food safety remains a significant challenge despite the growth and development in agricultural research and the advent of modern biotechnological and agricultural tools. Though the agriculturist struggles to aid the growing population's needs, many pathogen-based plant diseases by their direct impact on cell division and tissue development have led to the loss of tons of food crops every year. Though there are many conventional and traditional methods to overcome this issue, the amount and time spend are huge. Scientists have developed systems biology tools to study the root cause of the problem and rectify it. Host-pathogen protein interactions (HPIs) have a promising role in identifying the pathogens' strategy to conquer the host organism. In this paper, the interactions between the host Rhynchophorus ferrugineus (an invasive wood-boring pest that destroys palm) and the pathogens Proteus mirabilis, Serratia marcescens, and Klebsiella pneumoniae are comprehensively studied using protein-protein interactions, molecular docking, and followed by 200 ns molecular dynamic simulations. This study elucidates the structural and functional basis of these proteins leading towards better plant health, production, and reliability.

Prescribed burning reduces species richness of wood-decay fungi in the forests of northwest Arkansas.

The present study, which was carried out at three localities in the Ozark Mountains of northwest Arkansas, investigated the effects of prescribed burning on wood-decomposing fungi using samples of decaying woody debris (DWD) placed in plastic incubation chambers. One of the localities had not been subjected to recent prescribed burning, whereas the other localities contained both an unburned area as well as an area recently subjected to burning. In all three localities, small pieces of decaying woody debris (DWD) were collected, placed in the incubation chambers and the latter kept moist for any extended period of time. Pieces of DWD collected in the areas subjected to burning typically displayed evidence of considerable charring. Fruiting bodies appearing in the incubation chambers were removed and identified by sequencing of ribosomal DNA region. A total of 101 specimens representing 80 different taxa were recorded in the entire investigation, but the numbers of both specimens and taxa were appreciably higher for the unburned collecting sites. As such, the data obtained indicate that prescribed burning lowers the species richness of the wood-decomposing fungi associated with DWD at a particular locality. The unique aspect of the present study was the use of incubation chambers to characterize the taxa of fungi associated with CWD.
