Optoelectronic analysis of designed semi-circular shaped thiophene-based bridged Y-series NFAs for organic solar cell applications.

The highly adaptable optoelectronic and morphological properties of non-fullerene acceptors (NFAs) have made them a prominent research topic in the organic solar cell (OSC) field. This work describes the design of new molecules and investigates the potential optoelectronic aspects of remodified Y-series NFAs endowing with five new semi-circular shaped derivatives (BTPB1-BTPB5) based on the DFT-based quantum simulations. The designed molecules possess higher-lying LUMO energy levels with narrowed bandgaps and excellent coherence between the acceptor and core via inserted bridges. The molecules demonstrate a significant red shift and a wide-ranging absorption spectrum extending from 400 nm to 1500 nm, with the most extensive absorption occurring in the near-infrared (NIR) region. Effective π-π stacking and drastically lower binding energy certify facile charge dissociation and transmission rate. Thiophene-based bridge modification decreased reorganization energy by 47 % which results in facile charge transmission and high current density. Theoretically, simulated PCE is achieved as high as 31.49 % owing to the higher-lying LUMOs. The results demonstrate the value of designing systems and exploring new possibilities for developing effective Y-series NFAs-based high-performance organic solar cells.

New semiconducting K2MgSiH6 (H = Cl & Br) halides have been investigated via DFT approach; their mechanical, optical, and structural properties were studied in detail.

Researchers are now avoiding perovskite materials containing lead due to their toxicity and instability in open air and heat. In this study, our research group worked on potassium-based K2MgSiCl6 & K2MgSiBr6 perovskite compounds and thoroughly investigated these materials' basic behaviours. Goldschmidt and formation energy results certify the structure and thermodynamic stabilities of the studied compounds. The band gaps noted for the K2MgSiCl6 & K2MgSiBr6 perovskites were 2.42 eV & 1.88 eV, respectively. After the mechanical observations of the investigated compounds, it became apparent that both the studied compounds own brittle and anisotropic nature. Based on the tendency to absorb electromagnetic radiations both in the ultra-violet and visible range, it enables the K2MgSiCl6 & K2MgSiBr6 perovskites suitable for detectors, solar cells, and many other optoelectronic devices. The K2MgSiBr6 material showed the first response to the electromagnetic radiations in the visible range and acquired the optical conductivity value of 1219 (Ω.cm)-1; however, K2MgSiCl6 material showed its response to a bit higher energetic photons in the visible range than K2MgSiBr6 material, but its optical conductivity was higher (i.e., 1270 (Ω.cm)-1) than the K2MgSiBr6 material in the visible range.

Letter to editor: Trends and disparities in cardiovascular deaths in systemic lupus erythematosus: A population-based retrospective study in the United States from 1999 to 2020.

This letter addresses key limitations in the article "Trends and disparities in cardiovascular deaths in systemic lupus erythematosus: A population-based retrospective study in the United States from 1999 to 2020." While the article provides valuable insights into cardiovascular mortality among SLE patients, it overlooks critical factors such as medication adherence and sex-specific treatment responses, which could influence the reported outcomes. Additionally, the study's focus on cardiovascular deaths sidelines other relevant causes of mortality like infections and renal failure. Incorporating these considerations, along with a deeper exploration of socioeconomic disparities and healthcare infrastructure, could enhance future studies, offering a more comprehensive understanding of mortality trends in SLE patients.

A Novel MAG Variant Causes Hereditary Spastic Paraplegia in a Consanguineous Pakistani Family.

Background and objectives: Hereditary spastic paraplegia (HSP) is characterized by unsteady gait, motor incoordination, speech impairment, abnormal eye movement, progressive spasticity and lower limb weakness. Spastic paraplegia 75 (SPG75) results from a mutation in the gene that encodes myelin associated glycoprotein (MAG). Only a limited number of MAG variants associated with SPG75 in families of European, Middle Eastern, North African, Turkish and Palestinian ancestry have been documented so far. This study aims to provide further insight into the clinical and molecular manifestations of HSP. Methods: Using whole-exome sequencing, we investigated a consanguineous Pakistani family where three individuals presented with clinical signs of HSP. Sanger sequencing was used to carry out segregation analysis on available family members, and a minigene splicing assay was utilized to evaluate the effect of the splicing variant. Results: We identified a novel homozygous pathogenic splice donor variant in MAG (c.46 + 1G > T) associated with SPG75. RNA analysis revealed exon skipping that resulted in the loss of a start codon for ENST00000361922.8 isoform. Affected individuals exhibited variable combinations of nystagmus, developmental delay, cognitive impairments, spasticity, dysarthria, delayed gait and ataxia. The proband displayed a quadrupedal stride, and his siblings experienced frequent falls and ataxic gait as one of the prominent features that have not been previously reported in SPG75. Conclusions: Thus, the present study presents an uncommon manifestation of SPG75, the first from the Pakistani population, and broadens the spectrum of MAG variants.

Prevalence, Determinants, and Management Options of Scar Site Pregnancy in Women With Previous Cesarean Section: A Study From the Al-Qassim Region.

INTRODUCTION: Pregnancy located outside the uterine cavity following a cesarean section has become more prevalent in recent years due to the increase in cesarean section delivery. This study sought to investigate the prevalence, determinants, and treatment options of scar site pregnancy among women who sought maternal and child health services in a hospital in Buraydah, Al-Qassim region, Saudi Arabia. METHODS: Utilizing a quantitative retrospective case-control design, 50 women were recruited and assigned to the two groups evenly. Demographic data and risk factors were assessed using a questionnaire, and data were analyzed using SPSS version 27 at a 95% confidence interval and presented in tables and figures. RESULTS: Fifty-eight percent of the participants were aged 35 years and above, with 38% reporting a parity of 1-3. Logistic regression revealed that parity (odds ratio (OR) = 10.975, 95% confidence interval (CI) = 0.887-135.861, and p-value = 0.062), the interval between the last and present pregnancies (OR = 0.056, 95% CI = 0.005-0.668, p-value = 0.023), intrauterine contraceptive device (IUCD) use in the last year (OR = 0.070, 95% CI = 0.006 -0.780, p-value = 0.031) were statistically significant in predicting cesarean scar pregnancy. Combined methotrexate and aspiration were the most prevalent treatment options for scar site pregnancy in this study. CONCLUSION: Scar site pregnancy is a maternal health complication that affects women across all healthcare settings, and its prevalence is not clear due to underdiagnosis and underreporting. The risk of scar site pregnancy increased with an increase in the number of childbirths (parity) and the interval between the last and current pregnancies.

Synergistic effects of herpes oncolytic virus and cyclophosphamide for recurrent malignant glioma: a narrative review.

Gliomas, comprising nearly 80% of brain malignancies, present a formidable challenge with glioblastomas being the most aggressive subtype. Despite multidisciplinary care, including surgery and chemoradiotherapy, the prognosis remains grim, emphasizing the need for innovative treatment strategies. The blood-brain barrier complicates drug access, and the diverse histopathology hinders targeted therapies. Oncolytic herpes viruses (oHSVs), particularly HSV1716, G207, and rQNestin34.5v, show promise in glioma treatment by selectively replicating in tumor cells. Preclinical and clinical studies demonstrate the safety and efficacy of oHSVs, with T-Vec being FDA-approved. However, challenges like viral delivery limitations and antiviral responses persist. The combination of oHSVs and combining cyclophosphamide (CPA) addresses these challenges, demonstrating increased transgene expression and viral activity. The immunosuppressive properties of CPA, particularly in metronomic schedules, enhance oHSV efficacy, supporting the development of this combination for recurrent malignant gliomas. CPA with oHSVs enhances viral oncolysis and extends survival. CPA's immunomodulatory effects, suppressing regulatory T cells, improve oHSV efficiency. While obstacles remain, this synergistic approach offers hope for improved outcomes, necessitating further research and clinical validation.

Recent advances of 3D-printing in spine surgery.

Background: The emerging use of three-dimensional printing (3DP) offers improved surgical planning and personalized care. The use of 3DP technology in spinal surgery has several common applications, including models for preoperative planning, biomodels, surgical guides, implants, and teaching tools. Methods: A literature review was conducted to examine the current use of 3DP technology in spinal surgery and identify the challenges and limitations associated with its adoption. Results: The review reveals that while 3DP technology offers the benefits of enhanced stability, improved surgical outcomes, and the feasibility of patient-specific solutions in spinal surgeries, several challenges remain significant impediments to widespread adoption. The obvious expected limitation is the high cost associated with implementing and maintaining a 3DP facility and creating customized patient-specific implants. Technological limitations, including the variability between medical imaging and en vivo surgical anatomy, along with the reproduction of intricate high-fidelity anatomical detail, pose additional challenges. Finally, the lack of comprehensive clinical monitoring, inadequate sample sizes, and high-quality scientific evidence all limit our understanding of the full scope of 3DP's utility in spinal surgery and preclude widespread adoption and implementation. Conclusion: Despite the obvious challenges and limitations, ongoing research and development efforts are expected to address these issues, improving the accessibility and efficacy of 3DP technology in spinal surgeries. With further advancements, 3DP technology has the potential to revolutionize spinal surgery by providing personalized implants and precise surgical planning, ultimately improving patient outcomes and surgical efficiency.

Phyto-assisted synthesis of zinc oxide nanoparticles using Bauhinia variegata buds extract and evaluation of their multi-faceted biological potentials.

Zinc oxide nanoparticles have wide range biological, biomedical and environmental applications. However, traditional nanofabrication of ZnONPs uses various toxic chemicals and organic solvents which limit their bio-applications. To overcome this hurdle, Bauhinia variegata derived buds extract was utilized to fabricate ZnONPs. The greenly generated ZnONPs were successfully prepared and extensively characterized using different analytical tools and the average crystalline size was calculated as 25.47 nm. Further, bioengineered ZnONPs were explored for multiple biological activities that revealed excellent therapeutic potentials. The antibacterial potential was determined using different bacterial strains. Pseudomonas aeruginosa (MIC: 137.5 µg/mL) was reported to be the most resistant variant while Bacillus subtilis (MIC: 34.38 µg/mL) was observed to be most susceptible bacterial strain. DPPH radical scavenging potential was measured to determine the antioxidant capacity of ZnONPs and the highest scavenging potential was observed as 82% at highest of 300 µg/mL. The fungicidal effect of green ZnONPs in comparison with Amphotericin B was assessed against five selected pathogenic fungal strains. The results revealed, Fusarium solani (MIC: 46.875 µg/mL) was least resistant and Aspergillus flavus (MIC: 187.5 µg/mL) was most resistant in fungicidal examination. Cytotoxicity potential of B.V@ZnONPs was analyzed against newly hatched nauplii of brine shrimps. The results for greenly produced ZnONPs was recorded as 39.78 µg/mL while 3.006 µg/mL was reported for positive control vincristine sulphate. The results confirmed the category of general cytotoxic for greenly synthesized nano sized B.V@ZnONPs.

NOTCH3 p.Arg1231Cys is markedly enriched in South Asians and associated with stroke.

The genetic factors of stroke in South Asians are largely unexplored. Exome-wide sequencing and association analysis (ExWAS) in 75 K Pakistanis identified NM_000435.3(NOTCH3):c.3691 C > T, encoding the missense amino acid substitution p.Arg1231Cys, enriched in South Asians (alternate allele frequency = 0.58% compared to 0.019% in Western Europeans), and associated with subcortical hemorrhagic stroke [odds ratio (OR) = 3.39, 95% confidence interval (CI) = [2.26, 5.10], p = 3.87 × 10-9), and all strokes (OR [CI] = 2.30 [1.77, 3.01], p = 7.79 × 10-10). NOTCH3 p.Arg231Cys was strongly associated with white matter hyperintensity on MRI in United Kingdom Biobank (UKB) participants (effect [95% CI] in SD units = 1.1 [0.61, 1.5], p = 3.0 × 10-6). The variant is attributable for approximately 2.0% of hemorrhagic strokes and 1.1% of all strokes in South Asians. These findings highlight the value of diversity in genetic studies and have major implications for genomic medicine and therapeutic development in South Asian populations.

Safety and effectiveness of interference RNA (RNAi) based therapeutics in cardiac failure: A systematic review.

BACKGROUND: Heart failure is a major worldwide health concern and leading cause of mortality. RNAi interventions hold promise for patients resistant to conventional drugs due to their off-target effects and lack of specificity. OBJECTIVES: To examine the safety and effectiveness of RNAi therapeutics in treating heart failure. METHODS: The PubMed, Embase, Scopus and Cochrane databases were searched using appropriate keyword from inception until December 31, 2023. A total of 14 studies fulfilling predefined selection criteria were included for qualitative synthesis. RESULTS: We found that in patients with cardiac amyloidosis, patisiran and revusiran showed considerable improvements in cardiac output and left ventricular wall thickness. In animal studies, Nox2-siRNA showed effectiveness in regaining heart function. Furthermore, cardiomyocyte count and left ventricular function were improved by DUSP5 siRNA + T3 therapy and meg3 inhibition after myocardial infarction (MI). RNAi showed minimal adverse effects like peripheral neuropathy, hepatotoxicity, urinary tract infection, vaginal infection, diarrhea, abdominal pain arrhythmias, conduction disorders, and cardiotoxicity (LV wall thinning, heart failure) and improved cardiac biomarkers. CONCLUSION: RNAi therapeutics are novel treatment option for improving cardiac function because their high target specificity, ability to target genes that conventional drugs struggle to reach and potential for long-lasting effects. Further research on optimizing delivery methods, improving target specificity, evaluating long-term safety profiles and cost-effectiveness to fully realize their potential.

Rising mortality related to cardiovascular disease and prostate cancer amongst older men across the United States.

OBJECTIVE: There is a significant association between cardiovascular diseases (CVD) and prostate cancer (PCa), leading to high mortality. This study evaluates the trends in mortality associated with CVDs and PCa among older (≥ 65 years) men in the United States (US). METHODS: This analysis utilized the Centers for Disease Control and Prevention's Wide-Ranging Online Data for Epidemiologic Research (CDC WONDER). The analysis of Multiple Cause of Death Files was carried out from 1999 to 2019 to identify fatalities with CVD and PCa listed as either contributory or underlying causes of death. Crude and age-adjusted mortality rates (AAMRs) per 100,000 populations for variables such as year, race and ethnicity, and geographic regions were determined. To assess annual percent change (APC), a Joinpoint regression program was employed. RESULTS: Overall AAMR was 54.3 in 1999 and 34.6 in 2019. After a decline in AAMR from 1999 to 2015, an alarming rise in mortality was observed until 2019. Mortality rates were highest among Non-Hispanic (NH) Black and African American men (74.9). Geographically, the highest mortalities were witnessed in the West (46.4) and non-metropolitan areas (44.6). States with AAMRs ranking in the 90th percentile were Nebraska, California, North Dakota, the District of Columbia, and Mississippi. CONCLUSION: After decreasing death rates associated with CVD and PCa from 1999 to 2015, a reversal in the trend was observed from 2015 to 2019. Addressing this increase in death rates, especially among the vulnerable population, requires focused attention and targeted strategies to implement necessary safeguards in the upcoming years.

In-silico optimization of resveratrol interaction with nano-borophene: A DFT-guided study of supramolecular artistry.

In this study, the potential of borophene (BOR) as a drug delivery system for resveratrol (RVT) was explored to evaluate its efficacy in cancer treatment. The excited, electronic, and geometric states of RVT, BOR, and the borophene-adsorbed resveratrol complex (BOR@RVT) were calculated to assess BOR's suitability as a drug carrier. Noncovalent interaction (NCI) plots indicated a weak force of attraction between BOR and RVT, which facilitates the offloading of RVT at the target site. Frontier molecular orbital (FMO) analysis showed that during electron excitation from Highest Occupied Molecular Orbital (HOMO) to Lowest Unoccupied Molecular Orbital (LUMO), charge transfer occurs from RVT to BOR. This was further confirmed by charge decomposition analysis (CDA). Calculations for the excited state of BOR@RVT revealed a red shift in the maximum absorption wavelength (λmax), indicating a photoinduced electron transfer (PET) process across various excited states. PET analysis demonstrated fluorescence quenching due to this interaction. Our findings suggest that BOR holds significant potential as a drug delivery vehicle for cancer treatment, offering a promising platform for the development of advanced drug delivery systems.

Genome-Wide Identification of the CYP716 Gene Family in Platycodon grandiflorus (Jacq.) A. DC. and Its Role in the Regulation of Triterpenoid Saponin Biosynthesis.

The main type of saponins occurring in the root of Platycodon grandiflorus (Jacq.) A. DC. are oleanolic acid glycosides. The CYP716 gene family plays a major role in catalyzing the conversion of ß-amyrin into oleanolic acid. However, studies on the CYP716 genes in P. grandiflorus are limited, and its evolutionary history remains poorly understood. In this study, 22 PgCYP716 genes were identified, distributed among seven subfamilies. Cis-acting elements of the PgCYP716 promoters were mainly involved in plant hormone regulation and responses to abiotic stresses. PgCYP716A264, PgCYP716A391, PgCYP716A291, and PgCYP716BWv3 genes were upregulated in the root and during saponin accumulation, as shown by RNA-seq analysis, suggesting that these four genes play an important role in saponin synthesis. The results of subcellular localization indicated that these four genes encoded membrane proteins. Furthermore, the catalytic activity of these four genes was proved in the yeast, which catalyzed the conversion of ß-amyrin into oleanolic acid. We found that the content of ß-amyrin, platycodin D, platycoside E, platycodin D3, and total saponins increased significantly when either of the four genes was over expressed in the transgenic hair root. In addition, the expression of PgSS, PgGPPS2, PgHMGS, and PgSE was also upregulated while these four genes were overexpressed. These data support that these four PgCYP716 enzymes oxidize ß-amyrin to produce oleanolic acid, ultimately promoting saponin accumulation by activating the expression of upstream pathway genes. Our results enhanced the understanding of the functional variation among the PgCYP716 gene family involved in triterpenoid biosynthesis and provided a theoretical foundation for improving saponin content and enriching the saponin biosynthetic pathway in P. grandiflorus.

Integrated assessment of groundwater quality dynamics and Land use/land cover changes in rapidly urbanizing semi-arid region.

Rapid urbanization worldwide, poses numerous environmental challenges between escalating land use land cover (LULC) changes and groundwater quality dynamics. The main objective of this study was to investigate the dynamics of groundwater quality and LULC changes in Sargodha district, Punjab, Pakistan. Groundwater hydrochemistry reveals acceptable pH levels (<8) but total dissolved solids (TDS), electrical conductivity (EC) and HCO3- showed dynamic fluctuations by exceeding WHO limits. Piper diagrams, indicated dominance by magnesium and bicarbonate types, underscoring the influence of natural processes and anthropogenic activities. Major ion relationships in 2010, 2015, and 2021 showed a high correlation (R2 > 0.85) between Na+ and Cl-, suggesting salinization. whereas, the poor correlation (<0.17) between Ca2+ and HCO3- does not support calcite dissolution as the primary process affecting groundwater composition. The examination of nitrate contamination in groundwater across the years 2010, 2015, and 2021 was found to be high in the municipal sewage zone, suggesting a prevailing issue of nitrate contamination attributed to urban activities. The Nitrate Pollution Index (NPI) reveals a concerning trend, with a higher proportion of samples classified under moderate to high pollution categories in 2015 and 2021 compared to 2010. The qualitative assessment of nitrate concentration on spatiotemporal scale showed lower values in 2010 while a consistent rise from 2015 to 2021 in north-east and western parts of district. Likewise, NPI was high in the north-eastern and south-western regions in 2010, then reduced in subsequent years, which may be attributed to effective waste management practices and alterations in agricultural practices. The health risk assessment of 2010 indicated Total Health Hazard Quotient (THQ) within the standard limit, while in 2015 and 2021, elevated health risk was observed. This study emphasizes the need to use multiple approaches to groundwater management for sustainable land use planning and regulations that prioritize groundwater quality conservation.

Cu-nanoparticles enhance the sustainable growth and yield of drought-subjected wheat through physiological progress.

Drought stress (DS) is a significant abiotic stress that limits agricultural productivity worldwide. In semi-arid climates, one potential solution to alleviate the deleterious effects of drought is the use of soil amendments such as nanoparticles. The current research was conducted out to probe the sway of drought at critical growth stages (CGS) of wheat crop (D0: Control, D1: Drought at tillering stage, and D2: Drought at anthesis stage) and the application of Cu-nanoparticles (T0: 0 mg L-1, T1: 300 mg L-1, T2: 700 mg L-1, and T3: 950 mg L-1) in order to improve drought resilience. Results of the study revealed that DS considerably decreased the wheat growth and yield during CGS. However, Cu-nanoparticles application alleviated the detrimental backlash of DS and led to improvements in various aspects of wheat growth and yield, including plant height, spike length, 1000 grain weight, stomatal conductance, leaf chlorophyll content, water use efficiency, leaf turgor potential, relative water content, and ultimately the grain yield. The use of principal component analysis allowed us to integrate and interpret the diverse findings of our study, elucidating the impact of Cu-nanoparticle treatment on wheat growth and yield under drought. Overall, the study concluded that DS during the anthesis stage had the most significant negative impact on crop yield. However, applying Cu-nanoparticles at the rate of 300 mg L-1 proved to be an effective strategy for improving crop productivity by reducing the harmful effects of drought.

A Rare Case of Aggressive Non-Hodgkin's Lymphoma of the Muscle in a Young Male Presenting as Necrotizing Myofasciitis.

Non-Hodgkin's lymphoma (NHL) involving skeletal muscle is generally found to be a secondary metastasis and extremely rarely as a primary site of malignancy. Furthermore, in HIV patients, an increased incidence of lymphomas may be identified within the first six months of highly active antiretroviral therapy (HAART) initiation unmasked by immune reconstitution inflammatory syndrome (IRIS). We illustrate an extremely rare instance of NHL of the skeletal muscle in a young immunocompromised male with HIV/AIDS presenting as necrotizing myofasciitis complicated by compartment syndrome and hemodialysis-refractory type B lactic acidosis. A young Hispanic male with AIDS was admitted for acute left thigh pain and was soon found to have abscess formation with compartment syndrome requiring thigh fasciotomy. During the course of the ICU stay, the patient's clinical status acutely worsened with sepsis-induced multiorgan failure, including acute renal and acute liver failure requiring N-acetylcysteine and severe refractory metabolic acidosis requiring renal replacement therapy. Repeat imaging demonstrated diffuse myonecrosis. Left thigh muscle biopsy confirmed aggressive NHL of skeletal muscle. Despite months of arduous medical management in ICU, doxorubicin, vincristine, cyclophosphamide chemotherapy with concurrent high-dose prednisone for the vented patient, and intermittent curves of improvement, our patient succumbed to the nature of the disease and subsequently died from severe sepsis from the immunocompromised state. Interestingly, our patient's initial CD4 count was 1, which improved to 96 after five months of HAART, raising concerns for IRIS lymphoma. Given such rapid improvement with chemotherapy, the possibility of IRIS-related lymphoma, and the surprising dearth of data for chemotherapy use in critically ill patients on mechanical ventilation, more research is needed in these topics to better approach such complicated patients.

Association between depression and stroke risk in adults: a systematic review and meta-analysis.

Introduction: Stroke is a significant global health concern, and numerous studies have established a link between depression and an increased risk of stroke. While many investigations explore this link, some overlook its long-term effects. Depression may elevate stroke risk through physiological pathways involving nervous system changes and inflammation. This systematic review and meta-analysis aimed to assess the association between depression and stroke. Methodology: We conducted a comprehensive search of electronic databases (PubMed, Embase, Scopus, and PsycINFO) from inception to 9 April 2023, following the Preferred Reporting Items for Systemic Review and Meta-analysis (PRISMA) and Meta-analysis Of Observational Studies in Epidemiology (MOOSE) guidelines. We included all articles assessing the association between different stroke types and depression, excluding post-stroke depression. Two investigators independently extracted data and assessed quality using the Newcastle-Ottawa Scale and Cochrane Risk of Bias tool, utilizing a random-effects model for data synthesis. The primary outcome was the association of depression with stroke, with a secondary focus on the association of antidepressants with stroke. Results: The initial search yielded 10,091 articles, and 44 studies were included in the meta-analysis. The pooled analysis revealed a significant association between depression and stroke risk, with an overall hazard ratio of 1.41 (95% CI 1.32, 1.50; p < 0.00001), indicating a moderately positive effect size. Subgroup analyses showed consistent associations with ischemic stroke (HR = 1.30, 95% CI 1.13, 1.50; p = 0.007), fatal stroke (HR = 1.39, 95% CI 1.24, 1.55; p < 0.000001), and hemorrhagic stroke (HR = 1.33, 95% CI 1.01, 1.76; p = 0.04). The use of antidepressants was associated with an elevated risk of stroke (HR = 1.28, 95% CI 1.05, 1.55; p = 0.01). Conclusion and relevance: This meta-analysis indicates that depression moderately raises the risk of stroke. Given the severe consequences of stroke in individuals with depression, early detection and intervention should be prioritized to prevent it. Systematic review registration: Prospero (CRD42023472136).

The impact of biochar addition on morpho-physiological characteristics, yield and water use efficiency of tomato plants under drought and salinity stress.

The use of saline water under drought conditions is critical for sustainable agricultural development in arid regions. Biochar is used as a soil amendment to enhance soil properties such as water-holding capacity and the source of nutrition elements of plants. Thus, the research was carried out to assess the impact of biochar treatment on the morphological and physiological characteristics and production of Solanum lycopersicum in greenhouses exposed to drought and saline stresses. The study was structured as a three-factorial in split-split-plot design. There were 16 treatments across three variables: (i) water quality, with freshwater and saline water, with electrical conductivities of 0.9 and 2.4 dS m- 1, respectively; (ii) irrigation level, with 40%, 60%, 80%, and 100% of total evapotranspiration (ETC); (iii) and biochar application, with the addition of biochar at a 3% dosage by (w/w) (BC3%), and a control (BC0%). The findings demonstrated that salt and water deficiency hurt physiological, morphological, and yield characteristics. Conversely, the biochar addition enhanced all characteristics. Growth-related parameters, such as plant height, stem diameter, leaf area, and dry and wet weight, and leaf gas exchange attributes, such rate of transpiration and photosynthesis, conductivity, as well as leaf relative water content were decreased by drought and salt stresses, especially when the irrigation was 60% ETc or 40% ETc. The biochar addition resulted in a substantial enhancement in vegetative growth-related parameters, physiological characteristics, efficiency of water use, yield, as well as reduced proline levels. Tomato yield enhanced by 4%, 16%, 8%, and 3% when irrigation with freshwater at different levels of water deficit (100% ETc, 80% ETc, 60% ETc, and 40% ETc) than control (BC0%). Overall, the use of biochar (3%) combined with freshwater shows the potential to enhance morpho-physiological characteristics, support the development of tomato plants, and improve yield with higher WUE in semi-arid and arid areas.
