There is a large body of research on Ramadan intermittent fasting (RIF) and health in Muslim communities, that can offer insights to promote the achievement of Sustainable Development Goal 3 (SDG 3), which encompasses good health and well-being. Based on recent bibliometric evidence, we hypothesized that RIF research is highly relevant to SDG 3, pa...

Context Ramadan fasting (RF) is associated with various physiological and metabolic changes among fasting Muslims. However, it remains unclear whether these effects are attributable to changes in meal timing or changes in dietary energy and macronutrient intakes. Furthermore, the literature on the associations between RF, meal timing, and energy an...

The association between meal timing and energy and macronutrient intakes has to be more explored. To explore this potential relationship during Ramadan diurnal intermittent fasting (RDIF), a systematic review of the available literature assessing energy and macronutrient intakes before and during Ramadan was conducted. Studies that assessed energy,...

The large-scale dissemination of coronavirus disease-2019 (COVID-19) and its serious complications have pledged the scientific research communities to uncover the pathogenesis mechanisms of its etiologic agent, severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). Methods of unveiling such mechanisms are rooted in understanding the viral ag...

Aims Haptoglobin (Hp) is a multifaceted marker of inflammation, and mediates the interplay between obesity, inflammation, and cardiometabolic dysfunction. However, the role of the Hp phenotype in modulating intermittent fasting (IF)-induced changes in cardiometabolic markers remains to be elucidated. Methods Hp phenotype was determined for the stu...

Background and Objectives: Dietary modification is the principal approach to the management of hyperlipidemia in adults. Proprotein convertase subtilisin/kexin type 9 (PCSK9) is a key regulator of plasma cholesterol and a target for novel lipid-lowering pharmacotherapies. This study aimed to explore how circulating levels of PCSK9 changed during Ra...

There is a large body of research focused on various aspects related to Ramadan intermittent fasting (RIF) and human health and disease. This study aimed to quantify the bibliometric parameters of RIF medical research over the past seven decades and explore these parameters qualitatively via text mining analysis. We used the Scopus search engine to...

Aim and Background A growing body of evidence supports the impact of intermittent fasting (IF) on normalizing body weight and that the interaction between body genes and environmental factors shapes human susceptibility to developing obesity. FTO gene is one of these genes with metabolic effects related to energy metabolism and body fat deposition....

Background and aim: This study aims to quantify abdominal visceral adipose tissue (VAT) and subcutaneous adipose tissue (SAT) using T2-weighted magnetic resonance imaging (MRI), and assess the extent of its concordance with VAT surface-area measured by a state-of-the-art segmental multi-frequency bioelectrical impedance analysis (BIA) device. A co...

Background Levels of cortisol, melatonin, ghrelin, and leptin are highly correlated with circadian rhythmicity. The levels of these hormones are affected by sleep, feeding, and general behaviors, and fluctuate with light and dark cycles. During the fasting month of Ramadan, a shift to nighttime eating is expected to affect circadian rhythm hormones...

Melanin is a dark color pigment biosynthesised naturally in most living organisms. Fungal melanin is major putative virulence factor of Mucorales fungi that allows intracellular persistence by inducing phagosome maturation arrest. Recently, it has been shown that the black pigments of Rhizopus delemar is of eumelanin type, that requires the involve...

Objectives A mounting evidence confirms the effect of caloric restriction and intermittent fasting in ameliorating body oxidative stress and inflammation. A growing body of evidence supports that chronic inflammation and increased level of oxidative stress augment the way for the development of metabolic diseases, such as diabetes and cancers. Obje...

Aim Oxidative stress (OS) plays a major role in pathogenic mechanisms associated with metabolic syndrome (Mets) yet the main component of Mets contributing most to OS is not well elucidated. Hence, the aim of this study was to investigate the oxidative-antioxidative status in Mets subjects and to determine the main predicting component of OS. Meth...

Aims: The United Arab Emirates (UAE) ranks as the fifth most obese country with increasing cardio-metabolic risks. In this paper, relationships of salivary adipocytokines (markers of cardio-metabolic syndrome), diet quality and physical activity in 90 normal-weight, overweight and obese (30 subjects in each group) Emirati adult females were invest...

Unlike animals, plants are sessile organisms, lacking circulating antibodies and specialized immune cells and are exposed to various harsh environmental conditions that make them at risk of being attacked by different pathogens and herbivores. Plants produce chemo-signals to respond to the surroundings and be able to distinguish between harmless an...

Clinical and experimental observations have long suggested that elevated levels of estrogen associate with increased serum iron availability. Additionally, recent work has shown that estrogen can downregulate hepcidin synthesis in vitro. This study aims at assessing whether the ability of estrogen to downregulate hepcidin synthesis translates into...

Aims: Occurrence of metabolic syndrome (MetS) in the United Arab Emirates (UAE) is rising steadily, with subsequent increase in the prevalence of type 2 diabetes and cardiovascular disease (CVD). Recent studies have shown that PCSK9 plays a substantial role in atherogenic dyslipidemia. Hence, the aim of this study was to assess level of PCSK9 and...
