This study has provided new insights into the interaction between graphene and DNA nucleobases (adenine, cytosine, and guanine). It compares how each nucleobase interacts with graphene, examining their selectivity and binding energy. The research also explores how these interactions impact the electronic properties of graphene, showing potential applications in graphene-based biosensors and DNA sequencing technologies.

No research has, however, attempted to examine traditional foodstuffs in light of disasters and crises. Such research can provide a useful outlook on how traditional foodstuffs can aid households in a situation of disrupted food supply.

Using the RE-AIM implementation framework, we evaluated a multidisciplinary, primary level model of NCD care for Syrian refugees and vulnerable Jordanians delivered by MSF in Irbid, Jordan. We examined the programme's Reach, Effectiveness, Adoption and acceptance, Implementation and Maintenance over time.

Since 2014, Médecins Sans Frontières (MSF) has provided primary-level NCD services in Irbid, Jordan, targeting Syrian refugees and vulnerable Jordanians who struggle to access NCD care through the overburdened national health system. This retrospective cohort study explored programme and patient-level patterns in achievement of blood pressure and glycaemic control, patterns in treatment interruption, and the factors associated with these patterns.

Background: Most infectious diseases result from a lack of knowledge and poor personal hygiene. Hand hygiene, in particular, is one of the most common means by which pathogens are transmitted. The aim of this study was to determine college student's knowledge and awareness of personal hygiene in Kuwait.

The pathogen has many strains, so that diagnosis of the disease using culture method is not effective. The objective of this work was to evaluate the prevalence of Mycoplasma gallisepticum (MG) in Kuwait poultry farms using serology and molecular methods in comparison to the culture under specific conditions.

These methods are lengthy and labor-intensive and have been associated with a heightened risk of laboratory-acquired infection. Antibody based indirect detection methods also suffer from limitations in proper diagnosis of the organism.

Methods: Sixty cases of malaria falciparum were included in this study as patients. Thirty healthy individuals of comparable age, racial and body mass index were taken as controls.
Background: Respiratory infections are known to exacerbate wheezing in many asthmatic patients. We aimed to use molecular methods for the fast detection of Mycoplasma pneumoniae, Chlamydia pneumoniae and Legionella pneumophila in respiratory specimens from asthmatic patients in Kuwait.
Methods: We used uniplex PCR assays to detect the three atypical bacteria in clinical specimens from 235 asthmatic and non-asthmatic patients in Kuwait.
Background And Objectives: Varicella-Zoster virus (VZV) is a human herpes virus that usually attacks young children and commonly causes chicken pox (Varicella). Following primary infection, a lifelong latent infection is established. The virus often reactivates during adulthood or senesces to cause shingles (Zoster).

Subjects And Methods: Thirty patients of different ages and of both sexes with various types of leprosy were included in this study. In addition, 15 healthy individuals of comparable age and sex who had no family history of diabetes mellitus were identified as controls.
The prevalence of Legionella pneumophilia in water systems of residential facilities in Kuwait was performed during the period from November 2007 to November 2011. A total of 204 water samples collected from faucets and showerheads in bathrooms (n = 82), taps in kitchens (n = 51), and water tanks (n = 71), from different locations of residential facilities in Kuwait were screened for Legionella pneumophila by the standard culture method and by real time polymerase chain reaction (RT-PCR). Out of the 204 samples, 89 (43.

Subjects And Methods: Thirty seropositive HIV male patients selected from the Infectious Disease Hospital were classified into two groups according to their immunological and virological response to HAART. The first group included 15 male patients with low viral load and low CD4 counts; the second included 15 male patients with low viral load and high CD4 counts.

Methods: The present study was conducted from January 2005 to June 2006 in the Diabetic Clinic of Al-Amiri and Al-Sabah Hospitals in Kuwait City. Apolipoprotein E polymorphism was assessed in 250 subjects of which 83 were ischemic heart disease patients (41 diabetic and 42 non-diabetic) and 105 were diabetic patients without ischemic heart disease.
This study was undertaken to apply 16S rRNA sequence and Cellular Fatty Acid (CFA) composition analysis techniques for the identification and characterization of seven individual bacteria isolates obtained from seven infected fish samples. All samples were cultured on brain heart infusion agar. All the seven isolates were Gram positive and were identified as Streptococcus sp.

We evaluated the effect of meteorological factors and the occurrence of aerobiologicals on the number of asthma cases in Kuwait.
Methods: The number of daily asthma visits to the allergy center and emergency department at Al-Sabha Hospital for 1 year were examined on a monthly basis for correlation with major metereological factors (temperature, relative humidity, rain, wind speed and direction).
Objective: To evaluate genus- and species-specific polymerase chain reactions (PCRs) for the detection of the genus Legionella and the species Legionella pneumophila in clinical specimens and hospital water supplies, and to establish a simple and reproducible random amplification of polymorphic DNA (RAPD)-PCR technique for genotyping of Legionella.
Materials And Methods: A total of 70 respiratory tract specimens(bronchoalveolar lavage: n = 46; endotracheal secretions: n = 9; sputum: n = 15) from patients with atypical pneumonia, and 283 environmental samples (water: 20; swabs: 263) collected from water storage and supply facilities of the Mubarak Al-Kabeer Hospital, Kuwait, were tested by culture and genus-specific PCR for the detection of Legionella.

Myristyl nicotinate is an ester prodrug under development for delivery of nicotinic acid to skin for treatment and prevention of conditions that involve skin barrier impairment such as chronic photodamage and atopic dermatitis or for mitigating skin barrier impairment that results from therapy such as retinoids or steroids. The formulation stability of myristyl nicotinate is crucial because even small amounts of free nicotinic acid cause skin flushing, an effect that is not harmful but would severely limit tolerability. We report here reversed-phase HPLC methods for the rapid analysis of myristyl nicotinate and nicotinic acid in dermatological preparations.

View Article and Find Full Text PDFTissue deterioration and aging have long been associated with the accumulation of chemically induced protein and DNA damage. Reactive oxygen species (ROS) and reactive carbonyl species (RCS), especially alpha-dicarbonyl compounds, are key mediators of damage caused by oxidative stress, glycation, and UV-irradiation. The toxic effects of ROS are counteracted in vivo by antioxidants and antioxidant enzymes, and the deleterious effects of one RCS, methylglyoxal, are counteracted by a ubiquitous glyoxalase system.
