Target vs non-target analysis to determine pesticide residues in fruits from Saudi Arabia and influence in potential risk associated with exposure

2017

The occurrence of pesticide residues in fruits was determined by a target method for 62 analytes and a wide scope screening method against a database of 500 pesticides. Limits of quantification (LOQs) were from 0.5 to 6.3 μg kg−1 for the target method and from 0.5 to 119 μg kg−1 for the non-target. Thirty samples: dates, apples, oranges, tangerines, lemons and grapefruits were selected because their high consumption, except lemons and grapefruits that were to cover all citrus fruits. Using the target method, 15 compounds (mostly insecticides and fungicides) out of 62 pesticides (organophosphorus, carbamates, pyrethroids, chloroacetanilides, triazines, triazoles, imidazoles, etc.) were detec…

The dream of Abha. Note su una ricerca universitaria

2019

Il testo conduce una riflessione sugli esiti della ricerca condotta (in ambito universitario) sull'architettura islamica in Arabia Saudita. Si tratta, anzitutto, di un lavoro di studio e di riconoscimento dei caratteri tradizionali riguardanti lo spazio, il linguaggio, ma anche gli insediamenti che hanno caratterizzato il Paese nella sua storia recente e fino al tempo attuale. Inoltre, a partire dalle condizioni tramandate dalla dalla tradizione, si propone un ragionamento secondo il quale il progetto di architettura interpreta lo sviluppo sostenibile e coerente delle città. Ciò alla luce delle linee strategiche dettate da "Vision 2030", il programma con cui il Principe Salman bin Abdulaziz…

Molecular Basis of Hereditary C1q Deficiency

1998

Abstract Complete selective deficiencies of the complement component C1q are rare genetic disorders which are associated with recurrent infections and a high prevalence of lupus erythematosus-like symptoms. The improvements in molecular biology techniques have facilitated the analysis of such genetic defects to a great extend. To date the basis of C1q deficiencies from 13 families have been studied at the genetic level. In each case single base mutations leading to either termination codons, frame shift or amino acid exchanges were thought to be responsible for these defects as no other aberrations were found. In addition to DNA analysis, conventional immunochemical and biochemical methods …

Examining Anxiety, Sleep Quality, and Physical Activity as Predictors of Depression among University Students from Saudi Arabia during the Second Wav…

2022

Conducted during the second wave of the pandemic, this cross-sectional study examined the link between sleep quality, physical activity, exposure, and the impact of COVID-19 as predictors of mental health in Saudi undergraduate students. A convenience sample of 207 participants were recruited, 89% of whom were females and 94% were single. The measures included questionnaires on the level of exposure and the perceived impact of COVID-19, a physical activity measure, GAD-7, PHQ-9, and PSQI. The results indicated that approximately 43% of participants exhibited moderate anxiety, and 50% were at risk of depression. Overall, 63.93% of students exposed to strict quarantine for at least 14 days (n…

Keratocystic odontogenic tumor: A biopsy service’s experience with 104 solitary, multiple and recurrent lesions

2016

Background Keratocystic odontogenic tumor (KCOT) is a clinically significant cystic lesion of odontogenic origin. This study aimed to retrospectively review and describe the clinicopathologic features of KCOT and to objectively compare the clinical and histological features of solitary, multiple and recurrent KCOT in a Saudi Arabian population. Material and Methods Biopsy request forms, pathology records and archival materials (all histological slides) of 104 cases of KCOT from 75 patients were retrieved. Demographic and clinical details as well as histological evaluation were analyzed and compared between the 3 groups using chi-squared or Mann-Whitney tests of association as appropriate. R…

The potential for pneumococcal vaccination in Hajj pilgrims: expert opinion.

2013

Hajj is the annual pilgrimage to Mecca in the Kingdom of Saudi Arabia, and is one of the largest mass gathering events in the world. Acute respiratory tract infections are very common during Hajj, primarily as a result of close contact among pilgrims, intense congestion, shared accommodation and air pollution. A number of vaccines are (or have been) recommended for Hajj pilgrims in recent years. Several additional vaccines could significantly reduce the morbidity and mortality at Hajj and should be considered in health recommendations for pilgrims. Pneumococcal vaccines (particularly for those aged >65 years) are widely available, and have been shown to reduce the burden of disease associat…
