The aquatic ecosystem is negatively impacted by organic dye contamination, which is now one of the factors leading to environmental pollution. The present investigation involved the synthesis of nanocellulose (NC) and nanocellulose modified with NiO (NC/NiO) composite using acid hydrolysis and a one-step precipitation technique for NC and NiO, respectively. Malachite green (MG) dye was catalytically removed from an aqueous solution using the two products, which were mechanically homogenized.

Aims: Aging is influenced by genetic determinants and comorbidities, among which diabetes increases the risk for heart failure with preserved ejection fraction. There is no therapy to prevent heart dysfunction in aging and diabetic individuals. In previous studies, a single administration of the longevity-associated variant (LAV) of the human BPIFB4 gene halted heart decline in older and type 2 diabetic mice.

Background: Schistosomiasis affects approximately 250 million people worldwide, with 200,000 deaths annually. It has been documented that the granulomatous response to () oviposition is the root cause of progressive liver fibrosis in chronic infection, in 20% of the patients, and can lead to liver cirrhosis and/or liver cancer. The influence of helminths coinfection on schistosomiasis-induced liver pathological alterations remains poorly understood.

  • Rheumatic fever (RF), an autoimmune condition following untreated strep throat, mainly impacts children and can lead to serious heart issues, highlighting the need for awareness and prevention, especially in low-resource areas.
  • A study in Al-Baha, Saudi Arabia, surveyed 415 parents using an online questionnaire to evaluate their knowledge, attitudes, and practices regarding RF and RHD, revealing that most participants had poor knowledge and negative attitudes toward RF.
  • Results showed that only around 4.8% had good knowledge of RF, while 69.2% demonstrated good practices; females were more likely to have better practices than males, suggesting a need for enhanced educational initiatives by health authorities to improve understanding and prevention of these

Purpose: To evaluate the use, acceptability, and experience of a seven-item palliative care referral screening tool in an outpatient oncology setting.

Methods: A two-phase convergent parallel mixed-methods study. Patient participants who met any of the "Royal Marsden Triggers Tool" criteria were compared with those who did not in terms of demographic data, palliative care needs (Integrated Palliative Outcome Scale, IPOS) and quality of life indicators (EORTC-QLQ-C30).

Background: Major depressive disorder (MDD) is highly prevalent in youth. Conventional treatment paradigms primarily involve selective serotonin reuptake inhibitors (SSRIs) and psychotherapy, yet a significant proportion of this population exhibits treatment-resistant depression (TRD). In adults, interventional therapies like Electroconvulsive Therapy (ECT), repetitive Transcranial Magnetic Stimulation (rTMS), and ketamine have shown promise for TRD, but their comparative efficacy remains underexplored in Adolescent and pediatric population.

Metal nanoparticles, often supported on metal oxide promoters, are a cornerstone of heterogeneous catalysis. Experimentally, size effects are well-established and are manifested through changes to catalyst selectivity, activity and durability. Density Functional Theory (DFT) calculations have provided an attractive way to study these effects and rationalise the change in nanoparticle properties.

Testicular tumors are rare in children, representing a small percentage of pediatric solid tumors, with an incidence of 2 cases per 100,000 males. Teratomas, which are the most prevalent tumors in infants, may manifest in mature, immature, or malignant forms. While mature teratomas are typically found in the abdomen, intratesticular prepubertal-type teratomas in infants are infrequent.

  • Environmental contamination from pharmaceuticals like atenolol negatively affects non-target organisms, specifically adult zebrafish, which were exposed to varying concentrations for seven days.
  • The fish exhibited anxiety-like behaviors (e.g., increased bottom-dwelling and decreased vertical exploration) and showed heightened aggression without changing their social preferences.
  • Biochemical analyses revealed that atenolol disrupted antioxidant enzyme activities, caused oxidative stress, altered specific mRNA expressions (increased tph1 and decreased bdnf), and affected energy metabolism, which could threaten the fish's health and survival in their environment.
