The Potential Neuroprotective Effect of Cyperus esculentus L. Extract in Scopolamine-Induced Cognitive Impairment in Rats: Extensive Biological and Metabolomics Approaches.

The aim of the present study is to investigate the phytochemical composition of tiger nut (TN) (Cyperus esculentus L.) and its neuroprotective potential in scopolamine (Scop)-induced cognitive impairment in rats. The UHPLC-ESI-QTOF-MS analysis enabled the putative annotation of 88 metabolites, such as saccharides, amino acids, organic acids, fatty acids, phenolic compounds and flavonoids. Treatment with TN extract restored Scop-induced learning and memory impairments. In parallel, TN extract succeeded in lowering amyloid beta, ß-secretase protein expression and acetylcholine esterase (AChE) activity in the hippocampus of rats. TN extract decreased malondialdehyde levels, restored antioxidant levels and reduced proinflammatory cytokines as well as the Bax/Bcl2 ratio. Histopathological analysis demonstrated marked neuroprotection in TN-treated groups. In conclusion, the present study reveals that TN extract attenuates Scop-induced memory impairments by diminishing amyloid beta aggregates, as well as its anti-inflammatory, antioxidant, anti-apoptotic and anti-AChE activities.

In Vitro Anticancer Activity Screening of Novel Fused Thiophene Derivatives as VEGFR-2/AKT Dual Inhibitors and Apoptosis Inducers.

Protein kinases are seen as promising targets in controlling cell proliferation and survival in treating cancer where fused thiophene synthon was utilized in many kinase inhibitors approved by the FDA. Accordingly, this work focused on adopting fused thienopyrrole and pyrrolothienopyrimidine scaffolds in preparing new inhibitors, which were evaluated as antiproliferative agents in the HepG2 and PC-3 cell lines. The compounds 3b (IC50 = 3.105 and 2.15 µM) and 4c (IC50 = 3.023 and 3.12 µM) were the most promising candidates on both cells with good selective toxicity-sparing normal cells. A further mechanistic evaluation revealed promising kinase inhibitory activity, where 4c inhibited VEGFR-2 and AKT at IC50 = 0.075 and 4.60 µM, respectively, while 3b showed IC50 = 0.126 and 6.96 µM, respectively. Moreover, they resulted in S phase cell cycle arrest with subsequent caspase-3-induced apoptosis. Lastly, docking studies evaluated the binding patterns of these active derivatives and demonstrated a similar fitting pattern to the reference ligands inside the active sites of both VEGFR-2 and AKT (allosteric pocket) crystal structures. To conclude, these thiophene derivatives represent promising antiproliferative leads inhibiting both VEGFR-2 and AKT and inducing apoptosis in liver cell carcinoma.

Environment and sustainability approach to manage sweet bakery waste product.

Globalization and environmental regulations force organizations and producers to adopt sustainability in every aspect of their business. The concept of sustainability in manufacturing is now achieving maturity; however, there is still an opportunity to explore sustainability in perishable food items. The growth of population worldwide increased the amount of waste produced by the food industries. Enterprises worldwide use procedures to overcome the disposing of perishable waste into landfills, which has noticeable impacts on the environment and the business itself. However, these procedures may not be sufficient and lead to disturbance of the ecosystem. Therefore, the purpose of this article is to develop a framework to conduct experiments using Design of Experiment (DOE) to produce fertilizer using expired doughnuts from a well-known sweet bakery company in the United Arab Emirates. Firstly, we will develop a framework, implement waste management on perishable products such as doughnuts, and apply environmental, economic, and social development through recycling and composting it into fertilizers to be used for agriculture needs. Secondly, to study the impact of different parameters such as water, sand, doughnuts in different percentages on plant growth and survival. Results show that wasted doughnuts are suitable for fertilizer and the best plant due to interaction between all three factors: commercial fertilizer percentage, doughnuts percentage, and doughnuts size.

Predictors of Acne Vulgaris among Adolescents in Kuwait.

OBJECTIVES: The prevalence of acne vulgaris (AV) among adolescents in Kuwait has remained mostly unknown. This study aimed to estimate the prevalence of AV and its predictors among adolescents in Kuwait. SUBJECTS AND METHODS: A cross-sectional study was conducted on 714 participants who were randomly selected from public schools using multistage cluster random sampling. The presence or absence of AV, as well as severity of AV, were assessed using the Global Acne Grading Scale. Data on risk factors and potential confounders were collected from the parents through a self-administered questionnaire, and from the adolescents by face-to-face interview. Weight and height were measured in a standardized manner. RESULTS: Of 714 participants, 320 (44.8%; 95% CI 41.1-48.6%) self-reported AV. By clinical examination, AV was found among 479 (67.1%; 95% CI 63.5-70.5%) participants. Factors that were found to be significantly associated with AV in multivariable analysis were age, gender, nationality, and BMI categories. Females compared to males (adjusted prevalence ratio [APR] 1.16 [95% CI 1.05-1.25]; p = 0.006) and overweight or obese adolescents compared to normal weight (APR 1.15 [95% CI 1.02-1.26] and 1.14 [95% CI 1.02-1.23], respectively; p = 0.026) were more likely to have AV. None of the food items studied showed an association with AV in multivariable analysis. CONCLUSION: The prevalence of self-reported AV seems to be lower than that reported in other settings, while the prevalence of AV by clinical examination resembles that reported in many other countries. BMI was the only modifiable risk factor associated with AV in multivariable analysis, and none of the food items studied was related to the presence or absence of AV in multivariable analysis.

A rare cause of severe lactic acidosis.

Sarcoidosis is a multisystem disease of unknown aetiology with a classic histology of non-caseating granulomas. It most often occurs in those below the age of 50 years, and has a female preponderance. The main targets, often symptomless, are the lung and hilar lymph nodes, although liver involvement is not uncommon. Hepatic sarcoidosis encompasses a broad spectrum of presentations, from asymptomatic hepatic granulomas with slight liver function test derangement to severe liver involvement with cholestasis, advanced liver cirrhosis or chronic liver failure. Mortality due to acute liver failure is far less common than lung and heart involvement. We describe a case of fulminant liver failure with multiorgan failure presenting initially with chronic non-specific symptoms, in addition to minimal abnormal investigations such as mild anaemia, neutrophil leucocytosis and mild obstructive liver dysfunction. Presenting features included confusion, hypotension, oliguria and rapidly deteriorating liver function with severe lactic acidosis. Postmortem examination confirmed extensive systemic sarcoidosis.

Tuberculous meningitis, an unusual presentation in a young lady.

A 37-year-old Persian-speaking woman presented with epigastric pain, vomiting and non-specific frontal headache. Examination was unremarkable except for an isolated sixth nerve palsy found a few days after admission. Blood results were normal, as was the chest radiograph and the CT scan of the head. Initial cerebrospinal fluid (CSF) analysis revealed a significantly elevated protein level with reduced glucose, as well as CSF lymphocytosis. Tuberculosis (TB) meningitis was considered and she was commenced on anti-TB treatment before confirmation of the diagnosis. A full contact tracing was performed with regular follow-up with TB nurses. When she was seen in the clinic a month later, her symptoms had subsided completely.
