Role of Gold Nanoparticles in Drug Delivery
Get PDFRecent developments in nanotechnology offer a multitude of approaches for investigating and tracking diverse biological and medical processes at the nanoscale. Nanoparticles can deliver medications directly to cancer cells, aiding in the diagnosis and treatment of diseases like cancer. Gold nanoparticles (AuNPs) are incredibly small gold particles, usually fewer than 100 nanometers in size. They are measured in nanometers. AuNPs are one type of nanoparticle that has shown promise as a medication delivery platform. Their outstanding stability, adjustable chemical and physical characteristics, and biocompatibility make them incredibly beneficial for drug delivery applications. The physical and chemical features of AuNPs' natural characteristics were studied. Localized surface plasmon resonance (LSPR), radioactivity, and a high X-ray absorption coefficient are among the physical characteristics of AuNPs that are commonly used in diagnosis and treatment. Compared to many other nanoparticles, AuNPs can create stable chemical interactions with groups that contain S and N. As a result, AuNPs can bind to a broad range of chemical ligands or polymers used for particular purposes. According to recent research, AuNPs can be easily modified to allow the delivery of pharmaceutical drugs directly to the target tissue. This article provides a brief overview of the more effective synthesis method for AuNPs and how they can be utilized as drug carriers to improve precision medicine.

Evaluation of the Outcome of the Middle Turbinate Medialization (Fixation to Nasal Septum) by Various Surgical Technique
Get PDFThe primary objectives and essential aspects of ESS are to facilitate the proper drainage and ventilation of the afflicted groups of paranasal sinuses. The size and location of the middle turbinate directly impact the drainage of all paranasal sinuses.
A prospective study has been conducted in the otolaryngology department at Al-Imamain Al-kadhmain teaching hospital from September 2021 to May 2023 on 180 selected patients, divided into three groups; each contains sixty patients with the following specific surgical intervention: group I: medialization of the middle turbinate only, group II: medialization of the middle turbinate with fixation to the nasal septum, and group III: medialization of the middle turbinate with fixation to the nasal septum by trans-septal sutures. Postoperatively, follow-up was done weekly during the 1st month and every 2 weeks during the 2nd month by assessing symptom improvement and nasal endoscopic findings. The findings showed that one hundred (55.6%) patients were males and eighty (44.4%) patients were females. The patients' ages varied from 20 to 48 years (mean ± SD = (33.45 ± 8.95) years). Post-operative improvement of presenting symptoms in order of sequence from higher to lower were as follows: nasal obstructions (74%), nasal discharge (74%), facial pain (70%), smell disorders (61%), and headache (53%).
The current study concluded that the technique of middle turbinate medialization promotes effective drainage and ventilation, allowing for long-term monitoring and post-surgical suction clearing. Although it has its limits, the suturing method of the middle turbinate (conchopexy) is an efficient technique for preventing lateralization of the middle turbinate. This method has demonstrated superior overall outcomes when compared to iatrogenic adhesion (Bolgerization).

Suitability Evaluation of Pedons from Some Agricultural Communities on the Niger River Flood Plains in Bayelsa State, Nigeria
Get PDFFarmers under modern agriculture are expected to have direct or indirect knowledge of soil chemical and physical characteristics as well as their suitability for intended uses. This, however, is lacking in Bayelsa State, hence this study examined the potentials and limitations of some lower Niger River plain soils of southern Nigeria and their suitability for maize production. Based on landform differences, landscape segments were separated into three mapping units per location while profile pits were dug in each unit and morphologically described. Horizon differentiation guided soil sample collection followed by laboratory analysis. Silt loam dominated soil texture while Ca dominated the exchange complex but exchangeable bases concentration was generally low. Organic C, total N and available P concentrations were closely related and low which was attributed to land clearing and frequent bush burning. Excessive rainfall and inadequate length of day were the most limiting factors under climatic factors while temperature and relative humidity were highly suitable. The ELM3 and TFN3 pedons flooded each year by Nun and Forcados Rivers, respectively, were marginally suitable S3f. Texturally, ELM1, ELM2 and TFN1 were highly suitable (S1) while ELM3, TFN2 and TFN3 were moderately suitable (S2). Due to insufficient length of dry days and wetness challenges owing to excessive rainfall, all pedons were placed under actually not suitable but potentially suitable (N1) class. Improvement measures recommended included planting early in the dry spell to avoid excessive wetness and making available more dry days as well as organic matter conservation, avoiding frequent land clearing and bush burning.
