Calculus bovis in hepatocellular carcinoma: Tumor molecular basis, Wnt/ß-catenin pathway role, and protective mechanism.

In this editorial, we comment on the recent article by Huang et al. The editorial focuses specifically on the molecular mechanisms of hepatocellular carcinoma (HCC), mechanism of Wnt/ß-catenin pathway in HCC, and protective mechanism of Calculus bovis (CB) in HCC. Liver cancer is the fourth most common cause of cancer-related deaths globally. The most prevalent kind of primary liver cancer, HCC, is typically brought on by long-term viral infections (hepatitis B and C), non-alcoholic steatohepatitis, excessive alcohol consumption, and other conditions that can cause the liver to become chronically inflamed and cirrhotic. CB is a well-known traditional remedy in China and Japan and has been used extensively to treat a variety of diseases, such as high fever, convulsions, and stroke. Disturbances in lipid metabolism, cholesterol metabolism, bile acid metabolism, alcohol metabolism, and xenobiotic detoxification lead to fatty liver disease and liver cirrhosis. Succinate, which is a tricarboxylic acid cycle intermediate, is vital to energy production and mitochondrial metabolism. It is also thought to be a signaling molecule in metabolism and in the development and spread of liver malignancies. The Wnt/ß-catenin pathway is made up of a group of proteins that are essential for both adult tissue homeostasis and embryonic development. Cancer is frequently caused by the dysregulation of the Wnt/ß-catenin signaling pathway. In HCC liver carcinogenesis, Wnt/ß-catenin signaling is activated by the expression of downstream target genes. Communication between the liver and the gut exists via the portal vein, biliary tract, and systemic circulation. This "gut-liver axis" controls intestinal physiology. One of the main factors contributing to the development, progression, and treatment resistance of HCC is the abnormal activation of the Wnt/ß-Catenin signaling pathway. Therefore, understanding this pathway is essential to treating HCC. Eleven ingredients of CB, particularly oleanolic acid, ergosterol, and ursolic acid, have anti-primary liver cancer properties. Additionally, CB is important in the treatment of primary liver cancer through pathways linked to immune system function and apoptosis. CB also inhibits the proliferation of cancer stem cells and tumor cells and controls the tumor microenvironment. In the future, clinicians may be able to recommend one of many potential new drugs from CB ingredients to treat HCC expression, development, and progress.

Antimicrobial and Anti-Inflammatory Potential of Euphorbia paralias (L.): a bioprospecting study with phytoconstituents analysis.

Objectives: The phytochemicals in the aerial parts of Euphorbia paralias (also known as Sea Spurge) and their anti-inflammatory and antimicrobial activities were investigated. Methods: The methanolic extract was characterized using GC-MS and HPLC techniques. The anti-inflammatory feature was estimated through a Human Red Blood Cell (HRBC) membrane stabilization technique, while the antimicrobial feature was evaluated by the disc diffusion agar technique, minimum bactericidal concentration, and minimum inhibitory concentration (MIC) via micro-broth dilution method. Results: The GC/MS results demonstrated the existence of various phytochemicals, such as n-hexadecenoic acid, cis-11-eicosenoic acid, and methyl stearate, recognized for their anti-inflammatory and antibacterial features. The similarity of the phytochemical composition with other Euphorbia species emphasizes the genus-wide similarity. The anti-inflammatory activity exhibited a noteworthy inhibitory effect comparable to the reference drug indomethacin. The extract's antimicrobial potential was tested against a range of microorganisms, demonstrating significant action against Gram-positive bacteria and Candida albicans. The quantification of total phenolics and flavonoids further supported the therapeutic potential of the extract. Conclusion: The methanolic extract from E. paralias emerges as a successful natural source of important active constituents with potential applications as anti-inflammatory and antimicrobial agents. This research provides a first step to valorize Euphorbia paralias insights as a source of worthwhile phytochemicals that have potential applications in the pharmaceutical industry.

An Uncommon Consequence of Perforated Acute Appendicitis in Elderly Patients: Fournier's Gangrene.

Acute appendicitis that is not diagnosed and treated promptly typically results in serious complications that raise the risk of necrotizing fasciitis, particularly in elderly patients. We present a case of a 77-year-old male, who presented to the emergency department with a clinical manifestation of Fournier's gangrene caused by acute perforated appendicitis. The patient had no symptoms or signs of an acute abdomen, and within three days he developed significant unilateral scrotal swelling and skin changes. Our case demonstrates the need to treat Fournier's gangrene as a consequence of an intra-abdominal infectious disease, particularly in elderly comorbid patients with atypical symptoms of acute appendicitis, and highlights the importance of early surgical intervention.

Incidence and pattern of neurological emergencies in Ramadan.

BACKGROUND: The impact of Ramadan fasting on various neurological emergencies remains relatively unexplored. This study aimed to clarify the incidence and pattern of the different neurological emergencies in Ramadan compared to Shaaban. METHODS: In this cross-sectional study, all adult patients attending the emergency room at two Egyptian centers with neurological emergencies during Shaaban and Ramadan were evaluated. Clinical, laboratory, and radiological assessments were made on an individual basis upon which the diagnosis of neurological disorder was made. IBM SPSS Version 25 was used to analyze the data. RESULTS: Seventy-twenty patients were included, 382 during Shaaban and 338 during Ramadan. Among causes of delirium, the frequency of dehydration was significantly higher, and the frequency of illicit drug abuse was significantly lower during Ramadan compared to Shaaban (P = 0.004, 0.030, respectively). The incidence of ICH was significantly reduced during Ramadan compared to Shaaban (10.8% vs 19.7%, P = 0.031). The incidence of cardioembolic strokes significantly increased during Ramadan than Shaaban (40.5% vs 26.4%, P = 0.014), whereas the incidence of small vessel disease (SVD) significantly decreased during Ramadan than Shaaban (21.6% vs. 42.1%, P < 0.001). The incidence of a single seizure was significantly higher in Ramadan than in Shaaban (69.4% vs. 34.6%, P = 0.007). The incidence of functional neurological disorders was significantly reduced in Ramadan than in Shaaban (P < 0.001). CONCLUSION: The incidence of delirium caused by illicit drug abuse, ICH, SVD, and functional neurological disorders declined during Ramadan, while the incidence of delirium triggered by dehydration, cardioembolic strokes, and a single seizure increased during Ramadan.

Smoking is a predominant risk factor for coronary artery disease among Indians.

Smoking has emerged as a predominant risk factor for coronary artery disease (CAD) in India, contributing significantly to the country's rising cardiovascular morbidity and mortality rates. The adverse effects of tobacco on cardiovascular health are well-documented, exacerbating a public health challenge in a nation with a high prevalence of smoking. Therefore, it is of interest to analyse the impact of smoking on the incidence and progression of coronary artery disease among the Indian population, emphasizing the need for targeted public health interventions to mitigate this risk factor. We included 1000 adults were enrolled from January to July 2023. The group comprised 500 CAD patients (cases) and 500 individuals without CAD (controls). We gathered information on demographics, smoking habits & other CAD risk factors. To assess the relationships between smoking, CAD, and other variables, we utilized multivariate logistic regression. The analysis revealed that current smokers had a substantially increased likelihood of CAD, with an unadjusted odds ratio (OR) of 3.20 (95% CI: 2.45-4.18), compared to non-smokers. This association remained significant even after adjusting for confounders, with an adjusted OR of 2.80 (95% CI: 2.10-3.75). The study confirms smoking as a critical, Adaptable risk element for CAD, independently increasing the risk of the disease. Smoking significantly elevates the risk of developing coronary artery disease among Indians. Comprehensive anti-smoking campaigns and stringent tobacco control policies are imperative to reduce the burden of CAD. Public health strategies must focus on awareness, prevention, and cessation support to combat this major health threat effectively.

Quantitative assessment and genomic profiling of Campylobacter dynamics in poultry processing: a case study in the United Arab Emirates integrated abattoir system.

In the United Arab Emirates, no previous research has investigated the dynamics of the foodborne pathogen Campylobacter in broiler abattoir processing. This study conducted in one of the largest poultry producers in the UAE, following each key slaughter stage-defeathering, evisceration, and final chilling-five broiler carcasses were collected from 10 slaughter batches over a year. Additionally, one caecum was obtained from 15 chickens in each slaughter batch to evaluate the flock colonization. In total, 300 samples (150 carcasses and 150 caeca) were collected and enumerated for Campylobacter using standard methods. Campylobacter was pervasive in caecal samples from all slaughter batches, with 86% of carcasses post-defeathering and evisceration stages and 94% post-chilling tested positive for Campylobacter. Campylobacter coli predominates in 55.2% of positive samples, followed by Campylobacter jejuni in 21%, with both species co-existing in 23.8% of the samples. Campylobacter counts in caecal contents ranged from 6.7 to 8.5 log10 CFU/g, decreasing post-defeathering and evisceration to 3.5 log10 CFU/g of neck skin and further to 3.2 log10 CFU/g of neck skin post-evisceration. After chilling, 70% of carcasses exceeded 3 log10 CFU/g of neck skin. Whole-genome sequencing (WGS) of 48 isolates unveiled diverse sequence types and clusters, with isolates sharing the same clusters (less than 20 single nucleotide polymorphisms) between different farms, different flocks within the same farm, as well as in consecutive slaughter batches, indicating cross-contamination. Multiple antimicrobial resistance genes and mutations in gyrA T86I (conferring fluoroquinolone resistance) and an RNA mutation (23S r.2075; conferring macrolide resistance) were widespread, with variations between C. coli and C. jejuni. WGS results revealed that selected virulence genes (pglG, pseD, pseI, flaA, flaB, cdtA, and cdtC) were significantly present in C. jejuni compared to C. coli isolates. This study offers the first insights into Campylobacter dynamics in poultry processing in the UAE. This work provides a base for future research to explore additional contributors to Campylobacter contamination in primary production. In conclusion, effective Campylobacter management demands a comprehensive approach addressing potential contamination sources at every production and processing stage, guided by continued microbiological surveillance and genomic analysis to safeguard public health and food safety.

Green approach for fabricating hybrids of food waste-derived biochar/zinc oxide for effective degradation of bromothymol blue dye in a photocatalysis/persulfate activation system.

This study presents novel composites of biochar (BC) derived from spinach stalks and zinc oxide (ZnO) synthesized from water hyacinth to be used for the first time in a hybrid system for activating persulfate (PS) with photocatalysis for the degradation of bromothymol blue (BTB) dye. The BC/ZnO composites were characterized using innovative techniques. BC/ZnO (2:1) showed the highest photocatalytic performance and BC/ZnO (2:1)@(PS + light) system attained BTB degradation efficiency of 89.47% within 120 min. The optimum operating parameters were determined as an initial BTB concentration of 17.1 mg/L, a catalyst dosage of 0.7 g/L, and a persulfate initial concentration of 8.878 mM, achieving a BTB removal efficiency of 99.34%. The catalyst showed excellent stability over five consecutive runs. Sulfate radicals were the predominant radicals involved in the degradation of BTB. BC/ZnO (2:1)@(PS + light) system could degrade 88.52%, 84.64%, 81.5%, and 77.53% of methylene blue, methyl red, methyl orange, and Congo red, respectively. Further, the BC/ZnO (2:1)@(PS + light) system effectively activated PS to eliminate 97.49% of BTB and 85.12% of dissolved organic carbon in real industrial effluents from the textile industry. The proposed degradation system has the potential to efficiently purify industrial effluents which facilitates the large-scale application of this technique.

Extrapolation of Upadacitinib Efficacy in Juvenile Idiopathic Arthritis Leveraging Pharmacokinetics, Exposure-Response Models, and Real-World Patient Data.

Juvenile idiopathic arthritis (JIA) is the most prevalent pediatric rheumatic disease. While disease-modifying antirheumatic drugs (DMARDs), especially biologics, have greatly transformed the management of JIA, there remain some unmet medical needs that require new treatment options. The objective of this work was to describe and apply a modeling and simulation approach to extrapolate upadacitinib efficacy from the adult diseases, rheumatoid arthritis (RA) and psoriatic arthritis (PsA), to their respective pediatric diseases, polyarticular course JIA (pcJIA), and juvenile PsA (JPsA). A population pharmacokinetic model characterized upadacitinib pharmacokinetics in pediatric patients using data from two phase I studies in pediatric patients with pcJIA (N = 51) or atopic dermatitis (N = 33). Efficacy simulations were conducted using previously developed exposure-response models in adults with RA and PsA. Real-world pcJIA and JPsA patient databases were leveraged to construct representative patient profiles for the targeted population. Following administration of the proposed weight-based dosing regimen, the model-predicted median upadacitinib plasma exposures in pediatric patients were within 20% of those in adult RA and PsA patients receiving the approved adult regimen. Simulations demonstrate that upadacitinib efficacy in pcJIA and JPsA is predicted to be non-inferior to that in adults with RA or PsA, respectively. The results of this work enabled recent approvals of upadacitinib for the treatment of polyarticular JIA and JPsA in the United States. Upadacitinib safety in pediatrics is being further evaluated in ongoing clinical trials.

Nano-encapsulation of essential amino acids: ruminal methane, carbon monoxide, hydrogen sulfide and fermentation.

This study aimed to evaluate the effect of nano-encapsulation of four essential amino acids (AA), threonine, methionine, tryptophan, and lysine on in vitro ruminal total gas, methane, carbon monoxide, and hydrogen sulfide production as well as the rumen fermentation profile in cattle. The highest (P < 0.001) rate and asymptotic gas production after 48 h of incubation was observed in the diets that had threonine, followed by lysine, methionine, and tryptophan. Asymptotic methane gas production decreased in the following order: threonine > lysine > tryptophan > methionine (P < 0.0001) and the rate of production per hour followed the same trend (P = 0.0259). CH4 parameters showed that in 4 h, 24 h, and 48 h of incubation the lowest methane production was obtained in the diet with methionine (P < 0.05) and the highest one in diet supplemented with threonine. Methane fractions showed that methionine-containing diets resulted in more (P < 0.05) metabolizable energy versus methane, followed by tryptophan-containing, and then lysine-containing diets. Methionine-fortified diets seem to be the most eco-friendly among those studied regarding methane output. However, based on methane, CO, and H2S output as well as the rumen fermentation profile nano-encapsulated lysine is recommended for use in ruminant nutrition.

Tetraphenylanthraquinone and Dihydroxybenzene-Tethered Conjugated Microporous Polymer for Enhanced CO2 Uptake and Supercapacitive Energy Storage.

Conjugated microporous polymers (CMPs) feature extended excellent porosity properties and fully conjugated electronic systems, making them highly effective for several uses, including photocatalysis, dye adsorption, CO2 capture, supercapacitors, and so on. These polymers are known for their high specific surface area and adjustable porosity. To synthesize DHTP-CMPs (specifically TPE-DHTP CMP and Anthra-DHTP CMP) with abundant nitrogen (N) and oxygen (O) adsorption sites and spherical structures, we employed a straightforward Schiff-base [4 + 2] condensation reaction. This involved using 2,5-dihydroxyterephthalaldehyde (DHTP-2CHO) as the primary building block and phenolic OH group source, along with two distinct structures: 4,4',4″,4"'-(ethene-1,1,2,2-tetrayl)tetraaniline (TPE-4NH2) and 4,4',4″,4"'-(anthracene-9,10-diylidenebis(methanediylylidene))tetraaniline (Anthra-4Ph-4NH2). The synthesized Anthra-DHTP CMP had a remarkable BET surface area (BETSA) of 431 m2 g-1. Additionally, it exhibited outstanding thermal stability, as shown by a T d10 of 505 °C. Furthermore, for practical implementation, the Anthra-DHTP CMP demonstrates a significant capacity for capturing CO2, measuring 1.85 mmol g-1 at a temperature of 273 K and 1 bar. In a three-electrode test, the Anthra-DHTP CMP has a remarkable specific capacitance of 121 F g-1 at 0.5 A g-1. Furthermore, even after undergoing 5000 cycles, it maintains a capacitance retention rate of 79%. Due to their outstanding pore characteristics, abundant N and O, and conjugation properties, this Anthtra-DHTP CMP holds significant potential for CO2 capture and supercapacitor applications. This work will pave the way for the development of materials based on DHTP-CMPs and their postmodification with additional groups, facilitating their use in photocatalysis, photodegradation, lithium battery applications, and so on.

HPMC-Zein Film-forming Gel Loaded with 5-Fluorouracil Coupled with CO2 Laser Dermabrasion for Managing Stable Vitiligo.

Vitiligo is a significant dermatological challenge affecting 0.5 to 2% of the global population. Despite the various existing medical approaches, current vitiligo treatments are far from ideal. The present study aimed to prepare and evaluate a film-forming gel of 5 fluorouracil (5FU) using different ratios of hydroxypropyl methylcellulose (HPMC) and Zein for treating vitiligo. The prepared film-forming gels were fully characterized in terms of morphology, Fourier-transform infrared spectroscopy, drug content, pH, drying time, in-vitro drug release, and clinical investigation. A 32-full factorial design was used to study the impact of varying concentrations of HPMC (X1) and Zein (X2) on the percentage of 5FU released (Y1) from the prepared film-forming gels. Scanning electron microscopy (SEM) revealed a cross-linked network structure between polymers. An increase in HPMC concentration (2-4%) correlated with higher 5FU release, whereas increased Zein concentration (1-2%) resulted in reduced 5FU release. Furthermore, patients treated with 5FU film-forming gel after dermabrasion with fractional CO2 (FCO2) laser exhibited a significant decrease in JAK3 gene expression and higher effectiveness than those treated with FCO2 laser alone. Our results suggest that the film-forming gel of 5FU is promising as an effective formulation for treating vitiligo.

Exploring the Mechanisms and Therapeutic Approaches of Mitochondrial Dysfunction in Alzheimer's Disease: An Educational Literature Review.

Alzheimer's disease (AD) presents a significant challenge to global health. It is characterized by progressive cognitive deterioration and increased rates of morbidity and mortality among older adults. Among the various pathophysiologies of AD, mitochondrial dysfunction, encompassing conditions such as increased reactive oxygen production, dysregulated calcium homeostasis, and impaired mitochondrial dynamics, plays a pivotal role. This review comprehensively investigates the mechanisms of mitochondrial dysfunction in AD, focusing on aspects such as glucose metabolism impairment, mitochondrial bioenergetics, calcium signaling, protein tau and amyloid-beta-associated synapse dysfunction, mitophagy, aging, inflammation, mitochondrial DNA, mitochondria-localized microRNAs, genetics, hormones, and the electron transport chain and Krebs cycle. While lecanemab is the only FDA-approved medication to treat AD, we explore various therapeutic modalities for mitigating mitochondrial dysfunction in AD, including antioxidant drugs, antidiabetic agents, acetylcholinesterase inhibitors (FDA-approved to manage symptoms), nutritional supplements, natural products, phenylpropanoids, vaccines, exercise, and other potential treatments.

Smoking and cluster headache presentation and responsiveness to treatment.

BACKGROUND: Though an association between cluster headache (CH) and smoking has been postulated, data from the Middle East region is scarce. AIM OF WORK: To study the relationship between smoking and CH clinical characteristics and responsiveness to therapy in Egypt. METHODOLOGY: This was a prospective cohort hospital-based study conducted on patients with episodic and chronic CH in a tertiary headache clinic in Egypt during the period between 2019 and 2023. Patients were consecutively recruited at the time of their presentation and were followed up for two weeks after initiation of prophylactic treatment and steroids (as transitional therapy). RESULTS: Of 172 patients with CH recruited, 144 (83.7%) were smokers. Twenty-eight patients (16.3%) had chronic CH. The mean age was 42.08 ± 10.93 (20-66) years, and 131 (76.2%) were males. Smokers had a significantly higher median number of cluster bouts in the past five years (3.0 (IQR2.0-4.0) versus 2.0 (IQR 1.0-2.0)) and worse HIT-6 scores [51.0 (44.0-59.75) versus 41.0 (38.0-41.75)] than non-smokers (p < 0.001). The number of cluster bouts in the past five years was positively correlated with the smoking index (r = 0.249 (p = 0.006) and the smoking duration (in years) (r = 0.392 (p < 0.001)). HIT-6 scores were significantly correlated with the age at smoking onset (r=-0.190, = 0.023), smoking index (r = 0.519, p < 0.001), smoking duration (r = 0.611, p < 0.001), and number of cigarettes consumed per day (r = 0.392, p < 0.001). CONCLUSION: Smoking is significantly correlated with the daily frequency of CH attacks, the frequency of CH bouts in the past five years, and the HIT-6 scores among our cohort.

Racial and Ethnic Disparities in Neonatal Sepsis.

BACKGROUND: Sepsis is a significant health burden in the neonatal population. Although disparities in neonatal care have been reported, there are no data on racial/ethnic disparities in the context of sepsis. Therefore, we aimed to assess racial/ethnic disparities in the prevalence and outcomes of neonatal sepsis. METHODS: The national inpatient Kids' Inpatient Database produced by the Healthcare Cost and Utilization Project was used for the year 2019. The International Classification of Diseases, 10th revision codes were used to identify the primary outcome of the neonates diagnosed with sepsis. The χ2 and Fisher tests were used to calculate odds ratios for categorical variables, and logistic regression was performed to calculate adjusted odds ratio (aOR) to account for confounders in neonatal sepsis. RESULTS: Of the total 3,512,817 patients, 202,103 patients with neonatal sepsis were identified across all racial and ethnic groups. Overall prevalence was statistically significant in Black [aOR, 1.13 (95% confidence interval [CI], 1.10-1.17)], Hispanic [aOR, 1.19 (95% CI, 1.15-1.22)], Asian/Pacific Islander [aOR, 1.10 (95% CI, 1.05-1.16)] and Native Americans [aOR, 1.17 (95% CI, 1.04-1.31)] compared with Whites. In Black infants, the OR for the overall mortality was 1.35 (95% CI, 1.28-1.42), and sepsis-related mortality was 1.20 (95% CI, 1.06-1.35) compared to Whites. CONCLUSIONS: Although the prevalence of sepsis is marginally higher in Hispanic infants compared with Whites, the overall and sepsis-related mortalities are the highest in Black infants compared with all races and ethnic groups.

This study explores the development and performance of bistable materials, emphasizing their potential applications in aero-vehicles and high-stress environments. By integrating soft and hard materials within a composite structure, the research demonstrates the creation of bistable composites that exhibit remarkable flexibility and rigidity. Advanced simulations using COMSOL Multiphysics and 3D-printed prototypes reveal that these materials effectively absorb and dissipate stress, maintaining structural integrity under high-pressure conditions. Compression tests highlight the ability of bistable structures to bear significant loads, distributing stress efficiently across multiple layers. The innovative proposal of combining stiff and flexible materials within a single unit cell enhances bistable behavior, offering superior energy absorption and resilience. This work underscores the promise of bistable materials in advancing materials science, providing robust solutions for aerospace, automotive, and protective gear applications and paving the way for future research in optimizing bistable structures for diverse engineering challenges.

Salmonella in the food chain within the Gulf Cooperation Council countries.

Infections caused by bacteria originating from tainted food sources are a widespread concern due to their large economic impact and detrimental effects on public health. We aimed to explore literature focusing on the presence of Salmonella in the food supply chains of Gulf Cooperation Council (GCC) countries and to provide an overview of available information concerning health-related issues and the status of salmonellosis in humans in GCC countries. The reviewed evidence underscored a gap in our comprehensive understanding of the prevalence of Salmonella in the food supply of GCC countries. Molecular characterization efforts to pinpoint the sources of Salmonella in these nations were limited. Surveys targeting Salmonella in the food supply of GCC countries have been infrequent. While qualitative data indicated the presence or absence of Salmonella, there was a noticeable lack of quantitative data detailing the actual quantities of these bacteria in chicken meat supplies across GCC countries. Although reports regarding Salmonella in animal-derived foods were common, the literature highlighted in this review emphasized the persistent challenge that Salmonella pose to food safety and public health in GCC countries. Addressing this issue requires concerted efforts to enhance surveillance, improve control measures, and promote greater awareness among stakeholders in the food supply chain.

Relation between serum sclerostin and CTRP3 levels and bone mineral density in diabetic postmenopausal women.

BACKGROUND: Osteoporosis (OP) is a common finding in diabetic patients especially high-risk populations such as postmenopausal women. Sclerostin is a glycoprotein chiefly secreted by mature osteocytes and is considered a main regulator of bone formation. The C1q/TNF-Related Protein 3 (CTRP3) was found to be significantly associated with OP in postmenopausal women. The effect of type 2 diabetes mellitus (T2DM) on sclerostin and CTRP3 levels in postmenopausal women is rarely investigated. The present study aimed to assess the impact of T2DM on sclerostin and CTRP3 levels and their relation to OP in postmenopausal women. METHODS: The study included 60 postmenopausal women with T2DM and 60 age-matched postmenopausal non-diabetic women. Bone mineral density (BMD) was assessed using dual energy X-ray absorptiometry (DEXA). Serum levels of sclerostin and CTRP3 were assessed using enzyme-linked immunosorbent assay (ELISA) technique. RESULTS: Diabetic group expressed significantly higher serum levels of sclerostin when compared with non-diabetic group (110.0 ± 29.0 versus 51.5 ± 23.2 ng; p < 0.001). Oppositely, CTRP3 were significantly lower in the diabetic group (3.5 ± 3.5 versus 9.9 ± 3.7 ng/ml, p < 0.001). Multivariate logistic regression analysis identified HbA1c levels [OR (95% CI): 0.49 (0.26-0.93), p = 0.028], sclerotin levels [OR (95% CI): 1.06 (1.0-1.012), p = 0.041] and CTRP3 levels [OR (95%) CI: 1.64 (1.0-2.68), p = 0.047] as significant predictors of OP in diabetic patients. CONCLUSIONS: Sclerostin and CTRP3 levels are involved in OP in postmenopausal diabetic patients.

Facile synthesis of highly basic, nanocrystalline Fe2O3-NiO composites as promising and durable catalysts for selective dehydrogenation of 2-butanol.

Nanocrystalline Fe2O3-NiO composite catalysts were prepared using a sonication-assisted green preparation method. The prepared catalysts were characterized using different techniques, including thermal analyses (TGA/DTA), X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy, surface area measurements (SBET), and scanning electron microscopy (SEM). The surface basicity of the prepared catalysts was measured using the temperature-programmed desorption of CO2 (CO2-TPD) as a highly acidic probe molecule. The catalytic activity of all the prepared catalysts was tested at a temperature range of 250-325 °C towards the dehydrogenation of 2-butanol to methyl-ethyl ketone (MEK), which is considered a promising fossil fuel alternative and has several industrial applications. The composite catalysts showed better catalytic activity compared to the pure oxides (i.e., Fe2O3 and NiO) due to the strong synergetic effect between the two oxides. Fe2O3 prevented the coke formation over the surface of NiO by the oxygen-scavenging effect of Fe, which promotes the oxidation of the carbonaceous species and increases the catalyst's resistance to deactivation. The effect of weight hourly space velocity (WHSV) on the catalytic activity was tested over a selected catalyst. In addition, the stability and durability of the catalyst were tested across four successive reaction cycles, demonstrating remarkable performance throughout all the reaction cycles.

Ameliorative impacts of Sinapic acid against monosodium urate crystal-induced gouty arthritis and inflammation through different signaling pathways.

As known, gout a metabolic disease due to the urate crystals deposition in the joints and affect human health and state. Humans are looking for safe natural remedies from plants with safe, low cost and high effect on their health. Sinapic acid (SA) is found in plants and used as phytoconstituent in human diets. SA has strong antioxidant activity, bone-regenerative, anti-cancer, anti-allergic, and antidiabetic effects. The current study was outlined to confirm the anti-gout potential of SA against monosodium urate crystals (MSU)-induced gouty arthritis in mice. Positive gouty arthritis was conducted by administration of colchicine and MSU in the hind paw. SA was orally administered to negative and positive MSU arthritic mice at 25 and 50 mg/kg, one-hour before MSU injection (100 µg/kg intra-articular). At the end of the experiment, sampling was done for serum, histopathology, oxidative stress and gene expression analysis. The results showed that SA significantly recovered the joint edema and recovered MSU crystals-showed histopathological changes. The production of cytokines, leukocyte recruitment, oxidative stress, and nucleotide-binding domain, leucinerich-containing family, pyrin domain-containing-3 (NLRP3)-inflammasome genes expressions were increased in positive arthritic mice and ameliorated significantly by SA administration. Moreover, SA showed ameliorative impacts on air pouch model of mice as reported by the down regulation in the expression of inflammation related blood cells, proinflammatory cytokines and other transcriptional genes. In conclusion, sinapic acid showed a potential therapeutic use against side effects accompanying gouty arthritis and is good as a supplement against inflammation associated disorders.

Placental abruption and the risk of necrotizing enterocolitis in neonates with birth weight ≥1500 grams; US national database study.

BACKGROUND: The pathogenesis of necrotizing enterocolitis (NEC) is multifactorial, placental abruption is associated with serious neonatal complications attributed to disruption of the maternal-fetal vascular interface. This study aimed to investigate the association between placental abruption and NEC. METHODS: We analyzed the United States (US) National Inpatient Sample (NIS) dataset for the years 2016-2018. Using the logistic regression model, the adjusted odds ratios (aOR) were calculated to assess the risk of NEC in infants born to mothers with placental abruption after controlling for significant confounders. Analyses were repeated after stratifying the population into two birth weight (BW) categories: <1500 g and ≥1500 g. RESULTS: The study included 11,597,756 newborns. Placental abruption occurred in 0.16% of the population. NEC was diagnosed in 0.18% of infants, with a higher incidence (2.5%) in those born to mothers with placental abruption (aOR = 1.2, 95% CI: 1.1-1.3, p < 0.001). Placental abruption was associated with NEC only in infants with BW ≥ 1500 g (aOR = 1.34, 95% CI: 1.11-1.62, p 0.003). CONCLUSION: Placental abruption is associated with an increased risk of NEC in neonates with BW ≥ 1500 g. Research is needed to explore the mechanisms behind this association and to develop targeted interventions to mitigate NEC risks in this population. IMPACT: Placental abruption is associated with an increased risk of developing necrotizing enterocolitis (NEC) in neonates with a birth weight ≥1500 grams. This effect could be via direct in utero bowel injury or due to indirect postnatal compromise that occurs in these infants. This is the first study to specifically address the association between placental abruption and NEC in neonates ≥1500 g. The study used a national dataset that included all neonates delivered in the US, thereby allowing for the generalization of the findings after adjustment for multiple confounding factors. This study lays the groundwork for subsequent studies aimed at modifying feeding strategies and other neonatal management for the prevention of NEC in infants delivered after placental abruption.
