Substituent Effect on Pyridine Efficacy as a Chelating Stabilizer

Owing to the growing interest and unique properties of pyridines as bases, effects of substitution and substituent modification on electron density enrichment of the pyridyl nitrogen, and thus the effectiveness of pyridine as metal ion-stabilizers will be introduced in this chapter. Pyridines of the structure C5(S)nH5-nN (S = substituent) that have been intensively studied theoretically were selected as examples to prove the concept of this chapter. Computational results in the reviewed reports showed that: substitution and substituent modification significantly affect the electronic enrichment of nitrogen atom of the pyridine. The conclusions extracted from the covered investigations were employed to promote pyridines to act as efficient stabilizers for the coordinated metal ions. In coordination chemistry, these kinds of coordinated complexes are highly demanded in the field of chemosensation

Jurisprudential and Legal Perspectives on the Protection of Rights and Freedoms in the 2021 Basic Statute of the Sultanate of Oman

In this paper, we examine the constitutional protection of economic rights and freedoms in the Basic Statute of the Sultanate of Oman. Through descriptive, analytical, and historical approaches, the study identifies the protection and mechanisms for attaining social justice according to the Basic Statute to achieve Omans 2040 vision. The study concludes that courts must refrain from applying laws that violate the Basic Statute, and that weak guarantees of economic and social rights and freedoms hinder their protection and prevent the achievement of Oman Vision 2040. The study recommends spreading a culture of human rights and education on economic, social, and cultural rights, as well as adhering to international human rights conventions and covenants ratified by Oman

Biodegradation of Crude Oil Using Aspergillus species

Biodegradation of crude oil is a process that utilizes the capability of microorganism to degrade toxic pollutant in the environment. In the present study, three fungal species were isolated from the soil contaminated with crude oil in the oil fields in Basrah. The fungal species belongs to the genus Aspergillus, which are A. flavus ,A .fumigatus and  A .versicolar. Their ability to biodegrade crude oil was tested as single isolates for 15 and 30 days of incubation in the mineral salts medium,the results showed that the fungus A. flavus was the best, with biodegradation ability reaching 60% in 15 days and 80% in 30 days . Keywords:crude oil, fungi, biodegradation. DOI: 10.7176/JBAH/9-4-0

Determination of Carbendazim Fungicide and Oxymatrine Insecticide Residues in the Soils of Four Agriculture Stations in Basrah Governorate by HPLC

The current study was concentrated on the determination of carbendazim fungicide and oxymatrine insecticide residues in four agriculture stations at Basrah governorate ; Abu Al-Kaseeb,Al-Hartha, Al-Zubair and ShattAl-Arab. High pressure liquid chromatography (HPLC) was used to determinedthe carbendazim residues  which range between (0-3.05µg/g) .The highest value 3.05µg/g was recorded in Shatt Al- Arab station while the lowest value was recorded in Al-Zubair station.oxymatrine residues range between (0-1.89 µg/g) and the highest value 1.89µg/g was recorded in  Al-Hartha station while the lowest value was recorded in Shatt Al- Arab station.There is no study on carbendazim and oxymatrine residues in soil, so this study was the first of its kind in the region which could be used as a baseline study for incoming study. Keywords: Oxymatrine, Carbendazim, Basrah soil, HPLC.

Exploring the adverse effects of chemotherapeutic agents used in the treatment of cervical and ovarian cancer from the patients' perspective: a content analysis of the online discussion forums.

OBJECTIVES: This study aimed to explore the adverse effects of chemotherapeutic agents used in the treatment of ovarian and cervical cancer by analysing patients' views posted in online discussion forums. METHOD: UK-centred online discussion forums were used to identify discussion threads on ovarian and cervical cancer between 2008 and 2017. The study was approved by the University of Bournemouth ethics committee. 272 discussion threads with 644 participants from four online discussion forums (Cancer Research UK, Macmillan, Ovacome and Jo's Cervical Cancer Trust) were identified. The threads were exported into NVivo and a thematic content analysis was conducted to identify study themes. RESULTS: Of the 644 participants, 19.4% had a diagnosis of cervical cancer and 80.6% had a diagnosis of ovarian cancer. Four main themes related to: (1) treatment plan, (2) adverse effects, (3) perception of treatment and (4) hospitalisation were identified. Patients' perceptions about their treatment were reported to be positive across all chemotherapeutic agents. 312 adverse effects were reported by patients with cervical cancer taking cisplatin, with fatigue (52.1%) and nausea (30.6%) being the two most frequently reported adverse effects. With regard to the treatment of ovarian cancer, 402 adverse effects were reported by patients on carboplatin and paclitaxel, with neuropathy (29.3%) and fatigue (28.0%) being the two most commonly reported adverse effects. CONCLUSION: The online discussion forums allowed patients to express their concerns in a blame-free environment that provided novel insight into the impact of chemotherapy-associated adverse effects on patients with cervical and ovarian cancers. Real-life experiences shared by patients can help the healthcare professionals to find the right balance between prolonged survival and quality of life

Does Haloperidol Prophylaxis Reduce Ketamine-Induced Emergence Delirium in Children?

Objectives: Ketamine is a non-barbiturate agent with rapid action onset that induces profound sedation; however, some emergency physicians tend not to use ketamine because of the risk of emergence delirium (ED). This study aimed to evaluate the effectiveness of haloperidol prophylaxis in postoperative ketamine delirium in children. Methods: Prospective data relating to any emergence dreams, delirium, hallucinations, agitation, crying, altered perceptions, and necessary interventions were recorded in consecutive cases of ketamine delirium in patients attending Mansoura University Hospital, Egypt, from June 2010 to May 2011. Results: A total of 537 records were available for analysis. Of those, 267 received prophylactic haloperidol (49.7%). There were significant differences between the two groups regarding post-anaesthetic care unit behaviour. The ketamine-haloperidol groups included more patients who were sleepy, calm (P ≤0.01) and less irritable (P ≤0.01), with a lower incidence of crying (P ≤0.01) and disorientation (P ≤0.01). Conclusion: We found that preoperative administration of haloperidol decreases the incidence of postoperative delirium in a sample of Egyptian children undergoing minor surgery. This is congruent with earlier work conducted in adults. This work carries great hope to decrease and even prevent ED in hospitalised, non-surgical patients
