Prevention from disease is currently the safest and most convenient alternative available. The present study aimed to evaluate the preventive and therapeutic effect of fifteen phytoconstituents from medicinal plants of Ayurveda against coronaviruses by in silico screening. All the phytoconstituents exhibited rapid GI absorption and bioavailability and most of them had no toxicity versus reference drug chloroquine. see more BAS analyses revealed that most of the phytocomponents had favorable bioactivity scores towards biological target proteins. Principal component analysis revealed that most of the phytoconstituents fell close to chloroquine in 3D projection of chemical space. Affinity of phytoconstituents towards SARS-CoV-2 spike protein-human ACE2 complex decreased as isomeldenin > tinosporaside > EGCG whereas in case of unbound ACE2, the strength of binding followed the order isomeldenin > tinosporaside > ellagic acid. Towards SARS-CoV-2 main and papain-like proteases, the affinity decreased as isomeldenin > EGCG > tinosporaside and EGCG > tinosporaside > isomeldenin, respectively. Most phytoconstituents displayed significant binding kinetics to the selected protein targets than chloroquine. SAR analysis revealed that isomeldenin, tinosporaside, EGCG and ellagic acid bind to viral spike glycoproteins via H-bond, Pi-Pi, Pi-sigma and Pi-alkyl type interactions. Molecular dynamics simulation of isomeldenin and EGCG with SARS-CoV and SARS-CoV-2 spike glycoproteins exhibited low deviations throughout the 100 ns simulation indicating good stability and compactness of the protein-ligand complexes. Thus, the above four phytoconstituents have the potential to emerge as prophylactic and therapeutic agents against coronaviruses if investigated further in vitro and in vivo.

To explore stressors among young university students.

Twenty-nine 18- to 25-year-old university students.

Four focus group discussions (n = 29) were conducted to explore mental health and stressors among domestic and international university students. Data was analyzed using thematic analysis to identify emerging themes and relationships.

Five primary stressors emerged from the data Balance, Interpersonal Relationships, Future Prospects, Performance Pressure and Financial Issues and Employment. Although many distinct relationships were identified between themes, "Balance" affected and influenced most other stressors.

Five stressors were identified, most of which related to a lack of balance and time-management. Too many competing commitments and difficulty prioritizing were key influences. Interventions and policy to address stressors in students may reduce student psychological stress. Universities can provide support for students to prioritize commitments, provide flexible study opportunities and offer financial guidance.

Health-risk behaviors have an unclear etiology and college students have elevated risk for engagement. Emotion dysregulation and several personality dimensions have been implicated in health-risk behaviors, but these constructs have rarely been studied together. Further, it is unknown if different types of health-risk behaviors have distinct etiologies.

2077 college students completed a cross-sectional survey.

Latent profile analysis discerned classes of participants from emotion dysregulation and personality dimensions. Differential engagement in self-injury, suicidality, disordered eating, substance misuse, and unprotected sex was evaluated across classes.

Three classes were identified, which were primarily distinguished by emotion dysregulation, urgency, and neuroticism. Health-risk behaviors generally increased across classes with increasing emotion-related constructs. Self-injury and suicidality demonstrated different patterns than other health-risk behaviors.

Results elucidate heterogeneity in health-risk behavior engagement. Focusing on emotional difficulties may be more important for reducing self-injury and suicidality than disordered eating, substance misuse, and risky sex.

The aim of the current study was to examine the dual role of personality and psychopathology in predicting substance use among first-year students.

103 first-semester undergraduate students were recruited via the university subject pool.

Participants completed personality questionnaires, structured clinical interviews, followed by the completion of diary entries each week reporting on substance use throughout their first semester.

Results indicated that a
diagnosis of an affective (mood/anxiety/stress) disorder was the most significant predictor of substance use. Personality and current psychopathology had no association to substance use.

This finding is consistent with developmental models of substance use relating to emotion-related disease and suggests that greater nuance is needed in understanding substance use risk in college students.

Periorbital ecchymoses or "raccoon eyes" in the neonate/infant may be due to basal skull fractures or neuroblastoma.

A term male baby born by vacuum-assisted delivery developed a medium size subgaleal hematoma on the first day of life (DOL). On the third DOL, bilateral periorbital ecchymosis (raccoon eyes) developed. The cerebral ultrasound, hematologic and coagulation studies were normal. The raccoon eyes were interpreted as an extension of the subgaleal hematoma to the orbital ridges. At DOL 38, he was thriving and the raccoon eyes were resolved.

"Raccoon eyes" may result from a subgaleal hematoma without fracture caused by birth trauma.

DNA binding studies of CT-DNA with prepared compounds in Tris-HCl/NaCl buffer were carried out by traditional UV-Visible and fluorescence spectroscopic methods, viscosity measurements and cyclic voltammetry. Results showed that the small scale of DMPMM had less activity to interact with biological systems and when it assembled on nickel nanoparticles surface the activity increased. Thermal denaturation and sonochemical denaturation studies of DNA with the presence and the absence of our compounds also were done by UV-Visible spectroscopic method and its results indicated that the synthesized compounds increased the denaturation temperature. BSA binding studies of synthesized compounds were done by UV-Visible and fluorescence spectroscopy. Molecular docking of prepared ligand and its nanoparticles with biomolecules (DNA and BSA) were studied. Antimicrobial studies of the DMPMM and DMPMM-NiNPs were carried out by Agar-Agar well diffusion method. Anticancer studies results evidenced that the synthesized DMPMM-NiNPs had good selectivity to control the growth of cancer cells without damaging the normal cells. Various antioxidant scavenging studies results have shown that DMPMM and DMPMM-NiNPs have significant antioxidant activity. link2 HighlightsStable and solid nickel nanoparticles were prepared.The size of the prepared nickel nanoparticles was nearly 3 to 8 nm.Organic ligand capped nickel nanoparticles interacted with DNA and BSA.Ni nanoparticles increased the denaturation temperature of DNA.It was found to have good anticancer activity with fewer side effects than cisplatin.Communicated by Ramaswamy H. link3 Sarma.
When a child or adult is referred for an autism diagnosis, clinicians from different backgrounds work together to make a diagnostic decision. A few studies have asked clinicians in interview how they feel about diagnosis and what the challenges are. We interviewed clinicians in child and adult assessment services in England, and from different professional backgrounds, about the challenges of autism diagnosis and the factors that might influence the assessment process. We found that there were a number of challenges in autism diagnosis, especially when someone coming for diagnosis was considered to be near the diagnostic threshold. Clinicians told us that making a diagnosis was like creating a 'narrative' looking at many different factors that told a story about a person, rather than just looking at the results of diagnostic tests. Clinicians do not always agree with the results of those tests and have to use their specialist clinical judgement to make decisions. Clinicians were concerned about the amount ooking at many different factors that told a story about a person, rather than just looking at the results of diagnostic tests. Clinicians do not always agree with the results of those tests and have to use their specialist clinical judgement to make decisions. Clinicians were concerned about the amount of time people have to wait for an autism assessment, and the resulting pressure on the assessment process. The findings of this work can help us to understand how diagnosis happens and consider ways in which it can be improved for adults, children and families coming for assessment, as well as clinicians.
Esculin, an active coumarin compound, has been demonstrated to exert anti-inflammatory effects. However, its potential role in non-alcoholic steatohepatitis (NASH) remains unclear.

This study explored the hepatoprotective effect and the molecular mechanism of esculin in methionine choline-deficient (MCD) diet-induced NASH.

Fifty C57BL/6J mice were divided into five groups control, model, low dosage esculin (oral, 20 mg/kg), high dosage esculin (oral, 40 mg/kg), and silybin (oral, 105 mg/kg). All animals were fed a MCD diet, except those in the control group (control diet), for 6 weeks.

Esculin (20 and 40 mg/kg) inhibited MCD diet-induced hepatic lipid content (triglyceride 16.95 ± 0.67 and 14.85 ± 0.78 vs. 21.21 ± 1.13 mg/g; total cholesterol 5.10 ± 0.34 and 4.08 ± 0.47 vs. 7.31 ± 0.58 mg/g), fibrosis, and inflammation (ALT 379.61 ± 40.30 and 312.72 ± 21.45 vs. 559.51 ± 37.01 U/L; AST 428.22 ± 34.29 and 328.23 ± 23.21 vs. 579.36 ± 31.93 U/L).
, esculin reduced tumour necrosis factor-α, interleukin-6, fibronectin, and collagen 4A1 levels, but had no effect on lipid levels in HepG2 cells induced by free fatty acid.
