RESUMO

Introduction: While different methods are employed for fixing narrowed nasal valves and preventing the notching of soft triangles, this study aims to demonstrate the effectiveness of a new technique called Süreyya-Dani Technique. Methods: This prospective study composed 100 patients who underwent rhinoplasty using the Süreyya-Dani technique. All patients presented with either notching of the soft triangle and/or external nasal valve dysfunction. Patients with the absence of soft triangle notching and external nasal valve dysfunction were excluded from this study. Facial analysis was conducted for all patients to identify any asymmetry in the face, and all nasal defects were identified. Descriptive statistics were calculated for different variables. Analytical statistics, namely Chi-Square test, was conducted with a significance level set at P < 0.05. Results: In the current study, 100 patients were involved, out of which 63 (63%) were female and 37 (37%) were male. The participants' ages ranged from 18 to 46 years, with a mean age of 30 years. various chief complaints were found among patients, with the majority 37(37%) expressing cosmetic concerns. A statistically significant difference was found for the association of nasal tip defects with genders, intraoperative findings, and chef complaints, and the association between the degree of external valve insufficiency and crural weakness (P-value < 0.05). Conclusion: Despite many techniques that have been put forward to fix narrowed nasal valves and prevent notching of the soft triangle, the Süreyya-Dani Technique could work to prevent its occurrence successfully.

RESUMO

INTRODUCTION: Expanding the use of surface electromyography-biofeedback (EMG-BF) devices in different therapeutic settings highlights the gradually evolving role of visualizing muscle activity in the rehabilitation process. This review evaluates their concepts, uses, and trends, combining evidence-based research. AREAS COVERED: This review dissects the anatomy of EMG-BF systems, emphasizing their transformative integration with machine-learning (ML) and deep-learning (DL) paradigms. Advances such as the application of sophisticated DL architectures for high-density EMG data interpretation, optimization techniques for heightened DL model performance, and the fusion of EMG with electroencephalogram (EEG) signals have been spotlighted for enhancing biomechanical analyses in rehabilitation. The literature survey also categorizes EMG-BF devices based on functionality and clinical usage, supported by insights from commercial sectors. EXPERT OPINION: The current landscape of EMG-BF is rapidly evolving, chiefly propelled by innovations in artificial intelligence (AI). The incorporation of ML and DL into EMG-BF systems augments their accuracy, reliability, and scope, marking a leap in patient care. Despite challenges in model interpretability and signal noise, ongoing research promises to address these complexities, refining biofeedback modalities. The integration of AI not only predicts patient-specific recovery timelines but also tailors therapeutic interventions, heralding a new era of personalized medicine in rehabilitation and emotional detection.

RESUMO

Fascin-1 (FSCN1) is recognized as an actin-binding protein, commonly exhibits up-regulation in breast cancer (BC) and is crucial for tumor invasion and metastasis. The existence of FSCN1 gene polymorphisms may raise the potential for developing BC, and there are still no studies focusing on the relationship between the FSCN1 rs2966447 variant and BC risk in Egyptian females. Thus, we investigated the serum fascin-1 levels in BC patients and the association between the FSCN1 rs2966447 variant with its serum levels and BC susceptibility. Genotyping was conducted in 153 treatment-naïve BC females with different stages and 144 apparent healthy females by TaqMan® allelic discrimination assay, whereas serum fascin-1 level quantification was employed by ELISA. The FSCN1 rs2966447 variant demonstrated a significant association with BC susceptibility under all utilized genetic models, cancer stages and estrogen receptor negativity. Also, BC females with AT and TT genotypes had higher serum fascin-1 levels and tumor size than those with the AA genotype. Moreover, serum fascin-1 levels were significantly elevated in the BC females, notably in those with advanced-stages. Furthermore, serum fascin-1 levels were markedly positively correlated with number of positive lymph nodes as well as tumor size. Collectively, these findings revealed that the FSCN1 rs2966447 variant may be regarded as a strong candidate for BC susceptibility. Also, this intronic variant is associated with increased serum fascin-1 levels and tumor size.

RESUMO

Soil salinity is a major threat hindering the optimum growth, yield, and nutritional value of potato. The application of organic composts and micronutrients can effectively ameliorate the salinity-deleterious effects on potato growth and productivity. Herein, the combined effect of banana and soybean composts (BCo and SCo) application alongside foliar supplementation of boron (B), selenium (Se), cobalt (Co), and titanium (Ti) were investigated for improving growth, physiology, and agronomical attributes of potato plants grown in saline alluvial soil. Salinity stress significantly reduced biomass accumulation, chlorophyll content, NPK concentrations, yield attributes, and tuber quality, while inducing malondialdehyde and antioxidant enzymes. Co-application of either BCo or SCo with trace elements markedly alleviated salinity-adverse effects on potato growth and productivity. These promotive effects were also associated with a significant reduction in malondialdehyde content and activities of peroxidase and superoxide dismutase enzymes. The co-application of BCo and B/Se was the most effective among other treatments. Principle component analysis and heatmap also highlighted the efficacy of the co-application of organic composts and micronutrients in improving the salinity tolerance of potato plants. In essence, the co-application of BCo with B and Se can be adopted as a promising strategy for enhancing the productivity of potato crops in salt-affected soils.

RESUMO

INTRODUCTION: Thoracic outlet syndrome (TOS) typically considered a condition of the adult population; it is often disregarded in children and adolescents due to its limited recognition within the pediatrics. The current study aims to systematically review and provide insights into TOS among pediatric patients. METHODS: PubMed, Scopus, Web of Science, and Google Scholar databases were thoroughly searched for English language studies published until March 15th, 2024. The study included those articles focusing on pediatric or adolescent individuals diagnosed with TOS. Data collected from studies encompassed date of publication, number of participants or reported cases, age (years), gender of participants, type of TOS, affected side, type of treatment, surgical approach, bony abnormality, duration of symptoms (months), outcome, and follow-up time duration (months). RESULTS: The current study comprised 33 articles, 21 of which were case reports, 10 of which were case series, and the remaining were cohort studies. In this study, 356 patients were included. Females constituted 234 (65.73%) of the patient population. Among TOS types, neurogenic TOS was found among 201 (56.5%) patients. Sporting-related activity or physical activity was present in 193 (54%) patients, followed by a history of trauma in 27 (7%) patients. CONCLUSIONS: Pediatric patients exhibited a higher percentage of vascular TOS than their adult counterparts, with the supraclavicular approach emerging as the preferred treatment method. Sports-related activities were identified as the primary risk factor associated with pediatric TOS.

RESUMO

Lifestyle interventions can prevent type 2 diabetes (T2DM). However, some individuals do not experience anticipated improvements despite weight loss. Biomarkers to identify such individuals at early stages are lacking. Insulin-like growth factor 1 (IGF- 1) and Insulin-like growth factor binding protein 1(IGFBP-1) were shown to predict T2DM onset in prediabetes. We assessed whether these markers also predict the success of lifestyle interventions, thereby possibly guiding personalized strategies. We analyzed the fasting serum levels of IGF-1, IGFBP-1, and Insulin-like growth factor binding protein 2 (IGFBP-2) in relation to changes in metabolic and anthropometric parameters, including intrahepatic lipids (IHLs) and visceral adipose tissue (VAT) volume, measured by magnetic resonance imaging (MRI), in 345 participants with a high risk for prediabetes (54% female; aged 36-80 years). Participants were enrolled in three randomized dietary intervention trials and assessed both at baseline and one year post-intervention. Statistical analyses were performed using IBM SPSS Statistics (version 28), and significance was set at p < 0.05. Within the 1-year intervention, overall significant improvements were observed. Stratifying individuals by baseline IGF-1 and IGFBP-1 percentiles revealed significant differences: higher IGF-1 levels were associated with more favorable changes compared to lower levels, especially in VAT and IHL. Lower baseline IGFBP-1 levels were associated with greater improvements, especially in IHL and 2 h glucose. Higher bioactive IGF-1 levels might predict better metabolic outcomes following lifestyle interventions in prediabetes, potentially serving as biomarkers for personalized interventions.

RESUMO

Chlorpyrifos (CPF) is a broad-spectrum insecticide widely employed in agricultural field for pest control. Exposure to CPF is associated with serious effects to the main organs, including kidneys. Significant evidence denotes that oxidative stress (OS) and inflammation are implicated in CPF toxicity. This study aimed to evaluate the potential of farnesol (FAR) to modulate inflammatory mediators and farnesoid-X-receptor (FXR) and Nrf2 in a rat model of CPF nephrotoxicity. CPF and FAR were orally supplemented for 28 days and blood and kidney samples were collected for investigations. CPF administration elevated blood creatinine and urea, kidney MDA and NO, and upregulated NF-κB p65, IL-1ß, TNF-α, iNOS, and caspase-3. In addition, CPF upregulated kidney Keap1, and decreased GSH, antioxidant enzymes, and Nrf2, FXR, HO-1 and NQO-1. FAR ameliorated creatinine and urea, prevented histopathological alterations, decreased MDA and NO, and enhanced antioxidants in CPF-administered rats. FAR modulated NF-κB p65, iNOS, TNF-α, IL-1ß, caspase-3, Keap1, HO-1, NQO-1, Nrf2 and FXR. In silico investigations revealed the binding affinity of FAR towards Keap1 and FXR, as well as NF-κB, caspase-3, iNOS, and HO-1. In conclusion, FAR prevents CPF-induced kidney injury by attenuating OS, inflammation, and apoptosis, effects associated with modulation of FXR, Nrf2/HO-1 signaling and antioxidants.

RESUMO

BACKGROUND: Endodontic treatment aims to eradicate both microbial infection and inflammatory processes within the root canal space as well as in the periapical (PA) region of the tooth. To achieve this, the canals should be cleaned, shaped, disinfected, and obturated to the proper working length. Clinically, the working length is described as the measurement from the coronal reference point to the physiological apex located at the apical foramen. In the available literature, electronic apex locators (EAL) with periapical (PA) radiographs are the most reliable and precise tools for determining the working length in routine root canal treatment. Therefore, the aim of this retrospective clinical study is to evaluate if cone beam computed tomography (CBCT) scans are reliable and accurate in measuring endodontic working length compared to standard clinical measurement methods. METHODS: Patients who fit the inclusion criteria were identified. A postgraduate endodontic resident blinded to the cone beam computed tomography scan results treated all teeth in the field of view that needed endodontic treatment. The root canal length was determined using J Morita Root ZX II apex locator (J Morita Corp., Kyoto, Japan) and periapical radiographs. The dental radiology specialist interpreted the pre-existing cone beam computed tomography (CBCT) scan images and determined the working length. Statistical comparisons of the working length measurements of EAL and CBCT were performed using paired sample t-tests after verifying normality. RESULTS: No statistically significant differences in the working lengths were found in all canals with the exception of the palatal canal only (t=2.16, p=0.034), suggesting consistent measurements between EAL and CBCT. CONCLUSION: In teeth requiring endodontic treatment, pre-existing cone beam computed tomography scan images are accurate as electronic apex locators when determining the working length. A limitation of this study is that it only includes a limited number of samples and is affected by operator variation.

RESUMO

BACKGROUND: Abdominoplasty, an emerging surgical procedure worldwide, associated with complications, as seroma, infection, and hematoma. This systematic review and meta-analysis compare the outcomes of abdominoplasty procedures performed using a scalpel versus a diathermocoagulation device (diathermy monopolar electrocautery), aiming to find a safer approach with fewer complications. METHODS: We conducted a systematic search in November 2023 using PubMed, Ovid Medline, and Ovid Chocrane databases. The methodological index for nonrandomized studies and the Revised Cochrane Risk of Bias assessment tools were used to assess risk of bias for observational studies and randomized controlled trials, respectively. The data were analyzed using RevMan software. RESULTS: Six articles (1135 patients) were included, 521 patients were operated using a scalpel and 614 using electrocautery. Our analysis suggests that both seroma and drain output were seen more among the electrocautery group, with an odds ratio (OR) of 0.62 (95% CI [0.39, 0.97], p = 0.04) and - 103.63 (95% CI [- 205.67, - 1.59], p = 0.05), respectively. It is important to note the high heterogeneity seen among the studies discussing the total drain output. Additionally, we did not find any statistical significance between both techniques in terms of the rate of hematoma, wound infection, operation time, and hospital stay length. CONCLUSION: When comparing the use of scalpel and electrocautery dissection in abdominoplasty, higher rates of seroma and total drain output are significantly associated with electrocautery dissection.

RESUMO

Clinopodium menthifolium (wood calamint) is a folkloric medicinal plant ingested as a treatment for many human disorders including gastric disorders. Our study evaluates the anti-ulcer potentials of Clinopodium menthifolium ethanol extracts (CMEE) in induced gastric ulcers in rats. Thirty Dawley male rats were divided into 5 groups: normal and ulcer controls, treated orally with Tween 20%; reference rats treated with Omeprazole 20 mg/kg, and the remaining two groups received 250 and 500 mg/kg CMEE for 2 weeks. After that, food was taken away for 24 h, and then, rats received ethanol-induced gastric ulceration (except normal control), 80% (1 ml/rat). After anesthetization and sacrificing, the ulcer index, mucus content, and other ulcer measurements were obtained from dissected rat stomachs. Stomach tissues were also analyzed by different histology procedures and homogenized stomach tissues were assessed for their antioxidant contents. The toxicity trial showed the absence of any toxic signs in rats supplemented with 2 and 5 g/kg of CMEE. The gastroprotective results showed a significantly lower ulcer index and higher gastric mucin content in CMEE-ingested rats compared to ulcer controls. Furthermore, CMEE treatments significantly increased the intensity of periodic acid Schiff stained (PAS), HSP 70 protein, and down-regulation of Bax protein expression in the stomach epithelium. Rats supplemented with 500 mg/kg revealed noticeable changes in their serum inflammatory cytokines along with positive regulations of antioxidant enzymes. The outcomes provide a scientific backup behind the gastroprotective potential effect of CMEE that could serve as a natural resource against peptic ulcers.

RESUMO

The purpose of this research was to examine the potential effects of bentonite (BN) supplemented diets on growth, feed utilization, blood biochemistry, and histomorphology of Dicentrarchus labrax. Six treatments in triplicate were tested: B0, B0.5, B1.0, B1.5, B3.0, and B4.5, which represented fish groups fed diets supplemented with 0, 0.5, 1, 1.5, 3, and 4.5% BN, respectively. For 84 days, juveniles' seabass (initial weight = 32.73 g) were fed diets containing 46% protein, three times daily at 3% of body weight. With a 5% daily water exchange, underground seawater (32 ppt) was used. Findings revealed significant improvements in water quality (TAN and NH3), growth (FW, WG and SGR) and feed utilization (FCR, PER and PPV) in fish fed BN-supplemented diets, with the best values in favor of the B1.5 group. Additional enhancements in kidney function indicators (urea and uric acid) and liver enzymes were observed in fish of the BN-treated groups along with a decrease in cholesterol level in the B1.5 group. Further improvements in fish innate immunity (hemoglobin, red blood cells, glucose, total protein, globulin, and immunoglobulin IgM), antioxidant activity (total antioxidative capacity and catalase), and decreased cortisol levels in fish of the BN-treated groups. Histological examinations of the anterior and posterior intestines and liver in groups B1.5 and B3 revealed the healthiest organs. This study recommends BN at a concentration of 1.5% as a feed additive in the Dicentrarchus labrax diet.

RESUMO

Aim This study aimed to explore the morphology and complexity of mandibular anterior teeth in a Western Saudi Arabian sub-population using cone beam computed tomography (CBCT). Methodology CBCT scans from 818 patients were evaluated, and 3193 mandibular anterior teeth were analyzed for the number of roots, canal, canal configurations, separation level, bilateral symmetry, and gender associations. Results The results showed that all examined central and lateral incisors had a single root, and the majority exhibited a single canal. The prevalence of two canals in mandibular central and lateral incisors was 20.1% and 23.2%, respectively, resulting in an overall prevalence of 21.7% for two root canals in mandibular anterior teeth. The separation level of the two canals was predominantly located in the middle third of the root. Type I canal configuration was the most common, followed by type III. A high degree of bilateral symmetry in the number of canals and canal configurations was noted. Conclusion The findings contribute to the understanding of root canal anatomy in the Saudi population and provide valuable information for endodontic treatment planning.

RESUMO

In the current study, we evaluated the in vitro antibacterial efficacy of the roots' extracts of Jasminum officinale, Rosa damascene and Paeonia officinalis against MRSA (methicillin-resistant Staphylococcus aureus) by well diffusion technique. The root extract of P. officinalis exerted a potent anti-MRSA with MIC 0.4673 µg/ml, while both J. officinale and R. damascene exhibited very weak activity. Therefore, chemical profiling of the crude extract P. officinalis roots assisted by LC-HR-ESI-MS was performed and led to the dereplication of twenty metabolites of different classes, in which terpenes are the most abundant compounds. On a molecular level, network pharmacology was used to determine the targets of active metabolites to bacterial infections, particularly MRSA. Online databases PubChem, UniProt, STRING, and Swiss Target Prediction were used. In addition to using CYTOSCAPE software to display and analyze the findings, ShinyGO and FunRich tools were used to identify the gene enrichment analysis to the set of recognized genes. The results detected the identified metabolites were annotated by 254 targets. ALB, ACHE, TYMS, PRKCD, PLG, MMP9, MMP2, ERN1, EDNRA, BRD4 were found to be associated with MRSA infection. The top KEGG pathway was the vascular smooth muscle contraction pathway according to enrichment FDR. The present study suggested a possible implication of P. officinalis roots as a potent candidate having a powerful antibacterial activity against MRSA.

RESUMO

BACKGROUND: Health care providers (HCPs) caring for autistic children report more perceived psychological and emotional distress related to their job. However, not much is known about what can be done to mitigate such distress, especially in countries with limited mental health resources, such as Jordan. OBJECTIVE: This study aimed to examine the association between coping strategies (problem-focused, emotion-focused, and avoidant) and perceived emotional and psychological distress among HCPs of autistic children in Jordan. METHODS: In this cross-sectional study, a convenience sample of 180 HCPs working with autistic children in Jordan were recruited through autism centers and social media using an online self-administered questionnaire. RESULTS: The multiple linear regression analysis revealed that 31% of the variability in perceived emotional distress was explained by its significant association with problem-focused coping, emotion-focused coping, and avoidant coping. Likewise, 39% of the variability in perceived psychological distress was explained by its significant association with gender, having an immediate family, area of specialty, problem-focused coping, emotion-focused coping, and avoidant coping. CONCLUSIONS: The study shows that problem-focused coping significantly decreases perceived emotional distress, whereas emotion-focused and avoidant coping significantly increase perceived emotional distress. Avoidant coping significantly increases perceived psychological distress. Understanding the association between coping strategies and perceived emotional and psychological distress among HCPs can assist mental health nurses in identifying at-risk providers and providing timely emotional and psychological support.

RESUMO

Background: Student-centered learning strategy increases the likelihood of graduation of competent, self-dependent, and problem-solving physicians. The University of Bisha, College of Medicine (UBCOM) adopted self-directed learning (SDL) represented by problem-based learning (PBL), and directed self-learning (DSL) represented by team-based learning (TBL). Aim: To compare the students' performance in SDL and DSL among UBCOM students. Methodology: A total of 502 multiple choice questions (MCQs) from the mid-course and final exams were collected by the relevant subject experts from nine courses during the period from September 2020 till June 2023 that adopted PBL and TBL; 247 MCQs related to PBL and 255 related to TBL. Psychometric analysis was used to determine difficult, easy, and optimum questions (≤25%, ≥90%, and 26-89%, respectively). Point biserial as <0.19, 0.20-0.29, 0.30-0.39, and >0.40 which indicate poor, marginal, good, and excellent point biserial, respectively. Finally, the number of functional distractors was attempted by >5% of the candidates. Results: No significant differences were noted for the students' performance in MCQs related to PBL (representing self-directed, small group learning tool), and TBL (representing directed-self, large group learning tool) regarding difficulty index (DI), point biserial, and distractors functionality. Conclusion: It has been observed that there is no difference in students' performance whether PBL or TBL is used for learning Basic Medical Science courses. Small group learning such as PBL needs more resources in comparison to large group learning as in TBL, therefore any institute can decide on the adopted learning strategy depending on its resources and the number of students.

RESUMO

Pluchea dioscoridis is a flowering wild plant used traditionally in the treatment of rhematic disorders. This study investigated the phytochemical and in vitro radical scavenging activity (RSA), and in vivo anti-hyperlipidemic, antioxidant and anti-inflammatory properties of P. dioscoridis. The antihyperlipidemic efficacy was determined in a rat model of dyslipidemia. The extract and fractions of P. dioscoridis showed RSA with the EA fraction, exhibiting the most potent activity. The Phytochemical analysis of P. dioscoridis EA fraction (PDEAF) led to the isolation of five compounds (lupeol, quercetin, lupeol acetate, stigmasterol, and syringic acid). To evaluate its anti-hyperlipidemic effect, dyslipidemia three doses of PDEAF were supplemented to rats for 14 days and poloxamer-407 was administered on day 15 to induce dyslipidemia. All doses of PDEAF decreased plasma triglycerides, cholesterol, LDL and vLDL, and increased plasma LPL. PDEAF upregulated hepatic LDL receptor and suppressed HMG-CoA reductase, decreased lipid peroxidation and TNF-α and enhanced GSH and enzymatic antioxidants in dyslipidmeic rats. In silico findings revealed the binding affinity of the isolated compounds towards LPL, HMG-CoA reductase, and LDL receptor. In conclusion, P. dioscoridis is rich in phytoconstituents, exhibited RSA and its EA fraction effectively prevented acute dyslipidemia and its associated oxidative stress and inflammatory response.

RESUMO

Chamaerops humilis L. is clumping palm of the family Arecaceae with promising health-promoting effects. Parts of this species are utilized as food and employed in folk medicine to treat several disorders. This study investigated the phytochemical constituents of C. humilis leaves and their antioxidant and xanthine (XO) inhibitory activities in vitro and in acetaminophen (APAP)-induced hepatotoxicity in rats. Eleven compounds were isolated from C. humilis ethanolic extract (CHEE). CHEE and the butanol, n-hexane, and dichloromethane fractions exhibited in vitro radical scavenging and XO inhibitory efficacy. The computational findings revealed the tendency of the isolated compounds towards the active site of XO. In vivo, CHEE ameliorated liver function markers (ALT, AST, ALP, and albumin) and prevented tissue injury induced by APAP in rats. CHEE suppressed hepatic XO, decreased serum uric acid and liver MDA, and enhanced GSH, SOD, and catalase in APAP-treated rats. CHEE ameliorated serum TNF-α and IL-1ß in APAP-treated rats. Thus, C. humilis is rich in beneficial phytochemicals that possess binding affinity towards XO. C. humilis exhibited potent in vitro antioxidant and XO inhibitory activities, and prevented APAP hepatotoxicity by attenuating tissue injury, oxidative stress and inflammation.

RESUMO

BACKGROUND: We assessed the efficiency of intravenous adjuvants in decreasing opioid intake and pain scores after spine fusion surgery. METHODS: This study included 120 patients aged 18-60 listed for spine fusion surgery under general anesthesia. Patients were randomly assigned to four groups: Group (Lidocaine): received IV lidocaine 4 mg/kg in 50 mL volume over 30 min. Group (Magnesium): received IV magnesium sulfate 30mg/kg in 50 mL volume over 30 min. Group (combined Lidocaine and Magnesium): received IV lidocaine 4 mg/kg in 50 mL volume over 30 min.+IV magnesium sulfate 30mg/kg in 50 mL volume over 30 min. Group (Control): received IV saline 50 mL. The time to the first request analgesia, the postoperative pain score, total analgesic use, patient satisfaction, anxiety, depression, mental state, quality of life, and side effects were measured. RESULTS: The combined group had more extended time for the first analgesic request and fewer rescue analgesia doses than the other groups. NRS scores at rest or movement were statistically significantly lower in the lidocaine group and the combined group compared to the control group (P1, P3<0.05) at almost all times. This combination reduces anxiety and depression and improves overall health up to three months after a single infusion. The combined group had higher patient satisfaction. CONCLUSIONS: A synergistic effect of a combination of lidocaine and magnesium sulfate on perioperative pain was found.

RESUMO

BACKGROUND: Acacia nilotica Linn. is a widely distributed tree known for its applications in post-harvest and medicinal horticulture. However, its seed-based growth is relatively slow. Seed is a vital component for the propagation of A. nilotica due to its cost-effectiveness, genetic diversity, and ease of handling. Colchicine, commonly used for polyploidy induction in plants, may act as a pollutant at elevated levels. Its optimal concentration for Acacia nilotica's improved growth and development has not yet been determined, and the precise mechanism underlying this phenomenon has not been established. Therefore, this study investigated the impact of optimized colchicine (0.07%) seed treatment on A. nilotica's morphological, anatomical, physiological, fluorescent, and biochemical attributes under controlled conditions, comparing it with a control. RESULTS: Colchicine seed treatment significantly improved various plant attributes compared to control. This included increased shoot length (84.6%), root length (53.5%), shoot fresh weight (59.1%), root fresh weight (42.8%), shoot dry weight (51.5%), root dry weight (40%), fresh biomass (23.6%), stomatal size (35.9%), stomatal density (41.7%), stomatal index (51.2%), leaf thickness (11 times), leaf angle (2.4 times), photosynthetic rate (40%), water use efficiency (2.2 times), substomatal CO2 (36.6%), quantum yield of photosystem II (13.1%), proton flux (3.1 times), proton conductivity (2.3 times), linear electron flow (46.7%), enzymatic activities of catalase (25%), superoxide dismutase (33%), peroxidase (13.5%), and ascorbate peroxidase (28%), 2,2-diphenyl-1-picrylhydrazyl-radical scavenging activities(23%), total antioxidant capacity (59%), total phenolic (23%), and flavonoid content (37%) with less number of days to 80% germination (57.1%), transpiration rate (53.9%), stomatal conductance (67.1%), non-photochemical quenching (82.8%), non-regulatory energy dissipation (24.3%), and H2O2 (25%) and O-2 levels (30%). CONCLUSION: These findings elucidate the intricate mechanism behind the morphological, anatomical, physiological, fluorescent, and biochemical transformative effects of colchicine seed treatment on Acacia nilotica Linn. and offer valuable insights for quick production of A. nilotica's plants with modification and enhancement from seeds through an eco-friendly approach.

RESUMO

Suicide is a major public health concern, and university students are at higher risk of suicide than any other age group. The purpose of this study was to examine the prediction power of loneliness, academic anxiety, and academic procrastination on suicidality among university students. A cross-sectional, correlational design was used to recruit 403 university students using the electronic survey format in Jordan. Data were collected regarding loneliness, academic anxiety, academic procrastination, and suicidality. A two-step multiple hierarchical regression analysis was performed. Only 17.1% (n = 69) of students were at risk of suicide, low to moderate level of loneliness, moderate level and moderate to high level of academic procrastination of academic anxiety. The model that included the sociodemographic and the psychological factors was significant (F18,390 = 12.3, p < 0.001) where the total variance in suicidality was 37.3% (R2 = 0.373). Being a working student, being on psychotropic medication, romantic and family relationships domains of loneliness, and academic anxiety were found to be predictors of suicidality (p < 0.05). Suicide is a significant problem among university students. Mental health professionals and policymakers need to enhance the use and access to mental health services and seek psychological counselling to combat the increasingly observed phenomenon of suicide among young people.
