We aimed to explore the role of Indium (In), Terbium (Tb), Yttrium (Y), and Lanthanum (La) in the serum of women with recurrent pregnancy loss (RPL) and compare them to controls. Additionally, the study aimed to examine the relationship between REE levels and oxidative DNA damage, to identify potential risk factors contributing to RPL. This case-control study included 30 RPL cases and 30 controls with uncomplicated pregnancy.

Objective: To evaluate the levels of serum rare earth elements (REEs): lutetium [Lu], praseodymium [Pr], samarium [Sm], dysprosium [Dy], and cerium [Ce] in pregnant women with recurrent pregnancy loss (RPL) and evaluate their relationship with total antioxidant capacity (TAC) and 8-hydroxy-2'-deoxyguanosine (8-OHdG), a marker of DNA damage.

Methods: A case-controlled study was conducted on a cohort of 60 female participants, with first-trimester healthy pregnant women as the control group and pregnant women with a history of consecutive abortions as the recurrent pregnancy loss (RPL) group. Following blood collection, serum concentrations of Lu, Pr, Sm, Dy, and Ce were measured using an inductively coupled plasma mass spectrophotometer (ICP-MS).

Obesity is a pathological condition and a major risk factor for dyslipidemia, type 2 diabetes, and non-alcoholic fatty liver disease. Recent research highlighted the association of non-invasive serum markers with these conditions but the clinical utility of ALT APRI in obesity and its relationship with dyslipidemia remain unexplored. We examined the association of ALT APRI in 165 non-diabetic adults stratified by BMI and serum lipid parameters.

Introduction: Protein kinases (PKs) play key roles in cellular signaling and regulation cascades and therefore are listed among the most investigated enzymes with the intent to develop drugs that are able to modulate their catalytic features. Specifically, PKs are involved in chronic diseases of large impact in the society such as cancers and neurodegeneration. Since the approval of Fasudil for the management of cerebral vasospasm, frantic efforts are currently ongoing for the development of selective PK-modulating agents.

Although giant fennel is recognized as a "superfood" rich in phytochemicals with antioxidant activity, research into the antibacterial properties of its fruits has been relatively limited, compared to studies involving the root and aerial parts of the plant. In this study, seven solvents-acetone, methanol, ethanol, ethyl acetate, chloroform, water, and hexane-were used to extract the chemical constituents of the fruit of giant fennel (Ferula communis), a species of flowering plant in the carrot family Apiaceae. Specific attributes of these extracts were investigated using in silico simulations and in vitro bioassays.

Background: Hyperuricemia is linked to an increased risk of various chronic diseases, but data on the prevalence and association of hyperuricemia with liver function in Saudi Arabia are scarce.

Objectives: Evaluate the prevalence, association, and risk measures of hyperuricemia and liver function in the Saudi population.

Design: Retrospective, cross-sectional analysis.

Unpredictable chronic mild stress (UCMS) leads to variable metabolic effects. Oxidative stress (OS) of adipose tissue (AT) and mitochondrial energy homeostasis is little investigated. This work studied the effects of UCMS on OS and the antioxidant/redox status in AT and mitochondrial energy homeostasis in rats.

: The link between inflammation and anemia is well established but fluctuations in the emerging inflammatory index, neutrophil-lymphocyte ratio (NLR), in anemic subjects remain ambiguous. The purpose of this study is to address the prevailing knowledge gaps regarding the association of NLR with anemia in the Saudi population. : Laboratory results of NLR, C-reactive protein (CRP), and hemoglobin for 14,261 subjects were obtained from Al Borg Diagnostics and retrospectively analyzed.

Background: patients with locally advanced breast cancer (LABC) are often treated by neoadjuvant chemotherapy (NACT). This study aims to determine the prevalence of psychological distress and their sociodemographic and clinical factors in patients recently diagnosed with LABC and before NACT.

Methods: A total of 209 LABC patients without metastatic localization were recruited between 2021 and 2022 in the oncology hospital at Fez.

: Obesity is a chronic inflammatory condition and is considered a major risk factor for cardiovascular disease (CVD). The effects of obesity management via sleeve gastrectomy (SG) and lifestyle intervention (LS) on inflammatory cytokines, redox status, and CVD risk were studied in this work. : A total of 92 participants (18 to 60 years old) with obesity (BMI ≥ 35 kg/m were divided into two groups: the bariatric surgery (BS) group ( = 30), and the LS group ( = 62).

Polyunsaturated fatty acids (PUFAs) may favorably influence the risk and clinical course of diabetes mellitus (DM). In particular, eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and arachidonic acid (AA) alleviate oxidative injury and insulin resistance characteristic of DM. Uncertainty still remains, however, as to the composition and proportions of blood PUFAs in relation to fasting blood glucose levels.

Background: Abnormalities in fasting blood glucose (FBG) resulting in hypoglycemia (OG), impaired fasting glycemia (IFG), or hyperglycemia (HG) arise from disordered metabolic regulation caused in part by inflammation. To date, there is a dearth of evidence regarding the clinical utility of the monocyte−lymphocyte ratio (MLR), an emerging inflammatory index, in the management of dysglycemia. Methods: This retrospective, cross-sectional study explored MLR fluctuations as a function of glycemic control in 14,173 Saudi subjects.

Due to poor diagnosis breast cancer in women has emerged as the most common cause of death disease in developing countries. Medicinal plants have been used for thousands of years and can be useful in healthcare, especially in developing countries. Ethanol extracts of leaves of fire bush or arta ( EECC), exhibited significant anticancer potencies against two breast cancer cell lines, MCF-7 and MDA 231.

Inflammation is pivotal to the pathogenesis of diabetes mellitus (DM), but pathological alterations of the neutrophil−lymphocyte ratio (NLR), an emerging inflammatory index in DM management, remains understudied. The aim of this study is to examine the relationship between NLR and glycemic control in the Saudi population. Gender, age, WBC count, and fasting blood glucose (FBG) were obtained from Al-Borg Medical Laboratories for 14,205 subjects.

Selenium enhances the cellular antioxidant capacity and alleviates oxidative stress. We investigated the transcriptional and enzymatic activities of selenium-dependent glutathione peroxidase 1 and thioredoxin reductase 1 (TrxR1), and levels of glutathione, hydrogen peroxide, lipid peroxides, and protein carbonyls in primary passage 5 (P5) and senescent passage 25 (P25) and 30 (P30) fibroblasts. Cells were incubated in either standard Dulbecco growth medium (CM1) containing normal plasma selenium levels (0.

There is a paucity of detailed data related to the effect of senescence on the mitochondrial antioxidant capacity and redox state of senescent human cells. Activities of TCA cycle enzymes, respiratory chain complexes, hydrogen peroxide (HO), superoxide anions (SA), lipid peroxides (LPO), protein carbonyl content (PCC), thioredoxin reductase 2 (TrxR2), superoxide dismutase 2 (SOD2), glutathione peroxidase 1 (GPx1), glutathione reductase (GR), reduced glutathione (GSH), and oxidized glutathione (GSSG), along with levels of nicotinamide cofactors and ATP content were measured in young and senescent human foreskin fibroblasts. Primary and senescent cultures were biochemically identified by monitoring the augmented cellular activities of key glycolytic enzymes including phosphofructokinase, lactate dehydrogenase, and glycogen phosphorylase, and accumulation of HO, SA, LPO, PCC, and GSSG.

Article Synopsis
  • Organic extracts from willow leaves showed anticancer effects against breast, colorectal, cervical, and liver cancer cell lines, with specific activities linked to chloroform and ethyl acetate fractions.
  • These extracts caused cancer cell death through apoptosis, while minimally affecting non-cancerous cells, indicating a targeted therapeutic potential.
  • Additionally, the extracts enhanced pro-apoptotic protein levels and reduced anti-apoptotic markers, emphasizing the significant role of phenolic and flavonoid compounds as antioxidants and anticancer agents.
