Molekulare Nanodrähte aus einem Anthracen-9-(1,3-Butadien-)Derivat rollen sich auf, sobald sie Lichtpuls ausgesetzt werden. Das Aufrollen ist unabhängig von der Richtung Lichteinstrahlung und tritt bei Nanodrähten sowohl des E- als auch Z-Isomers auf. Die Formänderung wird durch eine E⇄Z-Photoisomerisierung angetrieben, die einen Nanodraht mit gemischten Isomeren erzeugt.

Simple, fast, large‐scale, and cost‐effective preparation of uniform controlled magnetic nanoparticles remains a major hurdle on the way towards magnetically targeted applications at realistic technical conditions. Herein, we present unique one‐pot approach that relies simple basic hydrolytic in situ coprecipitation inexpensive metal salts (Fe 2+ Fe 3+ ) compartmentalized by stabilizing fatty acids aided presence alkylamines. The synthesis was performed relatively low temperatures (~80°C)...

Nanowires composed of the anti-cancer drug Paclitaxel (Taxol) were fabricated using solvent annealing method inside Anodic Aluminum Oxide (AAO) templates. Surface modification AAO template with n-octadecyltrichlorsilane (OTS), prior to loading Taxol, prevented nanowires from agglomerating after dissolving in 20% phosphoric acid. Incorporating 0.4% sodium dodecyl sulfate (SDS) acid solution helped disperse nanowires. Using this we able fabricate tunable diameters (200, 80, 55, 35 and 18 nm)....

Oral isotretinoin is an effective agent for the treatment of severe cystic acne. Isotretinoin a teratogen; there increased risk congenital defects in infants exposed to drug uterus. The Saudi Food and Drug Authority (SFDA) has implemented pregnancy prevention program (PPP) protect females from those teratogenic effects.To investigate awareness women, reproductive age who were using or used it previously, about use SFDA-approved PPP Riyadh, Arabia.This cross-sectional study was conducted...

Introduction When COVID-19 vaccination started, there was little data on the safety of immunization against infection in pregnant women. Previous studies revealed no concerns for women or newborns who received a messenger ribonucleic acid (mRNA) vaccine during pregnancy. This study aimed to investigate effects and perinatal outcomes. Methods cross-sectional conducted maternity hospital King Saud Medical City. It started January 2022 ended June 2022. The questionnaire developed validated by...

Molecular crystal nanowires composed of an anthracene-9-(1,3-butadiene) derivative exhibit a rapid transition from straight to highly coiled structures when exposed pulse visible light. The curling does not depend on the direction light illumination and occurs for either E or Z isomer. shape change is driven by E⇄Z photoisomerization reaction that generates mixture isomers within single nanowire. As service our authors readers, this journal provides supporting information supplied authors....

Abstract Aims : The use of SGLT2 inhibitors during Ramadan may be unsafe (risk ketoacidosis, postural hypotension and dehydration), specifically long hours fasting in hot climates. objective this study was to determine the main risk factors associated with increased occurrence DKA among patients utilising assess Ramadan. Methods: This retrospective diagnostic assessed role 99 (50 men 49 women) declared diabetes mellitus treated empagliflozin followed-up clinics. variables were: 1....

BACKGROUND: The coexistence of coronary artery disease (CAD) and depression is a growing concern, as both conditions lead to disability. Although more prevalent in CAD patients than the general population has been associated with adverse cardiac outcomes, underlying mechanisms linking are not yet fully understood. This study aims assess prevalence postmyocardial infarction (MI) baseline data Saudi Arabia. MATERIALS AND METHODS: A cross-sectional was conducted at King Saud Medical City,...

We have fabricated surface‐modified paclitaxel nanowires (SM‐PNs) with a precise diameter and an average length of 50 μ m. The surface these is coated monolayer octadecylsiloxane (ODS), which prevents aggregation enhances dispersivity in aqueous media. This system constitutes novel drug delivery vehicle based on one‐dimensional (1D) nanostructures large to ratio. assayed the cytotoxicity different SM‐PNs (200, 80, 35, 18 nm) U937 cells compared their activity microcrystalline paclitaxel....

Accountable care organizations (ACOs) are becoming increasingly popular in healthcare order to improve quality, reduce costs, and enhance patient outcomes. ACOs an association of hospitals, providers insurers who assume financial medical responsibility for a population. In Saudi Arabia, the Ministry Health (MOH) has been tasked with delivering this strategy as part “Vision 2030” Kingdom Arabia. Implementing ACO strategies is complex process that requires careful planning, collaboration,...

Hydroxychloroquine (HCQ) and chloroquine were found to have positive results in some non-randomized clinical trials with more benefit decreasing the viral load of COVID-19. HCQ is a lysosomotropic lipophilic drug that can penetrate cell membranes, accumulates acidic lysosomes. The high concentration alkaline increases pH lysosomes from normal levels 4.7-4.8 6 which leads inhibition functions thus, prevents entry coronavirus into cells.
