RESUMO
Morphology (size, shape) and structural variations (bonding pattern, crystallography, and atomic arrangements) have significant impacts on the efficacy of the metallic nanoparticles. Fabrication of these metal nanoparticles through green synthesis using plant extracts has increased attention due to their low cost, less hazardous byproducts, and multiple applications. In present study, Eucalyptus globulus extract was used to synthesize silver nanoparticles (AgNPs). Change of color from light brown to reddish brown and UV-visible spectral peak at 423 nm confirmed the formation of AgNPs. The shifting of FTIR spectra peaks indicated the potential role of the functional groups in extract as capping agents. The DLS evaluated the average size and stability of the nanoparticles while the surface morphology, size and the elemental composition of the AgNPs was established by the FESEM and EDX analysis. The SEM images revealed spherical nanoparticles of size ranging from 40-60 nm. Biogenic AgNPs showed better DPPH radical scavenging activity with IC50 (13.44 ± 0.3) as compared to leaves extract with IC50 (10.57 ± 0.2). The synthesized AgNPs showed higher zones of inhibition (ZOI) by well diffusion method against Escherichia coli, Staphylococcus aureus and Klebsiella pneumoniae. Results of present study highlights the potential benefits of Eucalyptus globulus leaves extract-based AgNPs for various biomedical uses.

BACKGROUND: Roux-en-Y gastric bypass (RYGB) has consistently demonstrated excellent weight loss and comorbidity resolution. However, outcomes vary based on patient's BMI. Single anastomosis duodeno-ileostomy with sleeve (SADI-S) is a novel procedure with promising short-term results. The long-term outcomes of SADI-S in patients with BMI ≥ 50 kg/m2 are not well described. We aim to compare the safety and efficacy of SADI-S with RYGB in this patient population. METHODS: We performed a multicenter retrospective study of patients with a BMI ≥ 50 kg/m2 who underwent RYGB or SADI-S between 2008 and 2023. Patient demographics, peri- and post-operative characteristics were collected. Complication rates were reported at 6, 12, 24, and 60 months postoperatively. A multivariate linear regression was used to evaluate and compare weight loss outcomes between both procedures. RESULTS: A total of 968 patients (343 RYGB and 625 SADI-S; 68.3% female, age 42.9 ± 12.1 years; BMI 57.3 ± 6.7 kg/m2) with a mean follow-up of 3.6 ± 3.6 years were included. Patients who underwent RYGB were older, more likely to be female, and have a higher rate of sleep apnea (p < 0.001), hypertension (p = 0.015), dyslipidemia (p < 0.001), and type 2 diabetes (p = 0.016) at baseline. The rate of bariatric surgery-specific complications was lower after SADI-S compared to RYGB. We reported no bariatric surgery related deaths after 1 year following both procedures. SADI-S demonstrated statistically higher and sustained weight loss at each time interval compared to RYGB (p < 0.001) even after controlling for multiple confounders. Lastly, the rate of surgical non-responders was lower in the SADI-S cohort. CONCLUSIONS: In our cohort, SADI-S was associated with higher and sustained weight-loss results compared to RYGB. Comorbidity resolution was also higher after SADI-S. Both procedures demonstrate a similar safety profile. Further studies are required to validate the long-term safety of SADI-S compared to other bariatric procedures.

BACKGROUND: Approximately 5% of cancer patients in the United States presented with metastatic bone disease (MBD) at diagnosis. Current study explores the disparities in survival for patients with MBD. METHODS: Patients with the diagnosis of MBD at presentation for the five most common primary anatomical sites were extracted from Surveillance, Epidemiology, and End Results Census tract-level dataset (2010-2016). Kaplan-Meier and Cox Proportional Hazard models were used to evaluate survival, and prognostic factors for each cohort. Prognostic significance of socioeconomic status (SES) and insurance status were ascertained. RESULTS: The five most common anatomical-sites with MBD at presentation included "lung" (n = 59 739), "prostate" (n = 19 732), "breast" (n = 16 244), "renal and urothelium" (n = 7718) and "colon" (n= 3068). Lower SES was an independent risk factor for worse disease-specific survival (DSS) for patients with MBD originating from lung, prostate, breast and colon. Lack of insurance was an independent risk factor for worse DSS for MBD patients with primary tumors in lung and breast. CONCLUSIONS: MBD patients from the five most common primary sites demonstrated SES and insurance-related disparities in disease-specific survival. This is the first and largest study to explore SES and insurance-related disparities among patients specifically afflicted with MBD. Our findings highlight vulnerability of patients with MBD across multiple primary sites to financial toxicity.

Nonalcoholic fatty liver disease (NAFLD) is a complex metabolic-inflammatory disease associated with poor outcomes and decreased quality of life. NAFLD is overrepresented in patients with psychiatric disorders like depression, bipolar disorder, and schizophrenia; however, a comprehensive review on NAFLD and psychiatric disorders remains to be delineated. This review endeavors to investigate the association of NAFLD with psychiatric disorders, including shared pathogenesis and future clinical derivatives. Extant literature suggests that patients with psychiatric disorders (in particular, mood disorders) are more susceptible to the development of NAFLD due to multiple reasons, including but not limited to hypothalamic-pituitary-adrenal axis dysregulation, metabolic syndrome, and chronic perceived stress. Moreover, the clinical manifestations of mood disorders (e.g., anhedonia, psychomotor retardation, lifestyle modification, etc.), and potentially long-term treatment with weight-gaining agents, differentially affect these patients, making them more prone to NAFLD. Considering the increased morbidity associated with both mood disorders and NAFLD, our review recommends regular screenings for NAFLD in select patients with mood disorders exhibiting signs of increased risk (i.e., obesity, metabolic syndrome, diabetes, or family history of NAFLD) for better diagnosis and holistic care of both potentially interrelated conditions.
RESUMO
INTRODUCTION: Enhanced recovery after bariatric surgery pathways are associated with improved postoperative outcomes. This study aims to assess efficacy and safety of three novel protocol contributions (transversus abdominis plane blocks, ketamine and fosaprepitant), as well as their impact on length of stay (LOS) and on postoperative complications. METHODS: Effectiveness and safety were retrospectively investigated in patients who underwent Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy (SG) over a 6-year period in a single institution. Group 1 patients were not exposed to any of our suggested interventions, whereas Group 2 were exposed to all of three. RESULTS: Between January 2015 and August 2021, 1480 patients underwent primary SG (77.6%) or RYGB (22.4%); of those, 1132 (76.5%) and 348 (23.5%) were in Groups 1 and 2, respectively. Mean BMI and age were 45.87 versus 43.65 kg/m2 and 45.53 versus 44.99 years in groups 1 and 2, respectively. Suggested interventions were associated with lower operative times (84.79 ± 24.21 vs. 80.78 ± 32.8 min, p = 0.025). In Group 2, the mean LOS decreased in 0.18 day (1.79 ± 1.04 vs. 1.60 ± 0.90; p = 0.004). Overall complication rates were 8% and 8.6% for groups 1 and 2, respectively; readmission rates were 5.7% (64 pts) vs. 7.2% (25 pts), p > 0.05. Reoperations were less prevalent in Group 2 (1.5% vs. 1.1%; p = 0.79). CONCLUSION: Focus on optimized pain management, allied to a superior PONV control, may be relevant contributors for a lower LOS without negative impacts in complications rates.

INTRODUCTION: Despite frequent recognition of emotional blunting in the published literature, either as a primary symptom of depression or as an adverse effect of antidepressants, there is no systematic synthesis on this topic to our knowledge. We undertook this scoping review to assess the prevalence, clinical features, implicated causes and management of emotional blunting, outlining the phenomenological and clinical gaps in research. METHOD: A systematic search was done until March 15, 2022, to include all original studies (i.e., interventional trials, cohort & cross-sectional studies, case reports, and case series). All reviewed data were delineated to answer pertinent clinical, phenomenological, and management questions related to the phenomenon of emotional blunting. RESULTS: A total of 25 original studies were included in our scoping review. Emotional blunting was described as a persistent diminution in both positive and negative feelings in depressed patients, who could subjectively differentiate it from their acute symptoms. However, the literature lacked the distinction between emotional blunting as a primary symptom of depression or an adverse effect of antidepressants. Common clinical strategies to manage antidepressant-induced emotional blunting included dose reduction or switching to a different antidepressant. CONCLUSION: Emotional blunting was a significant patient-reported concern with antidepressants. Future research should clarify phenomenological and neurobiological constructs underlying emotional blunting to improve diagnostic and management skills.

BACKGROUND: Many people living with major depressive disorder (MDD) in China do not receive treatment owing to a lack of mental health services, along with significant stigma toward mental illness. Internet-based cognitive behavioral therapy (ICBT) has been proposed to increase access to mental health care for people with MDD. OBJECTIVE: The aims of this study were to (1) evaluate the efficacy of ICBT for depressive symptoms in patients with MDD; (2) evaluate the effect of ICBT on anxiety symptoms, nonspecific psychological distress, general self-efficacy, depression stigma, social function, and health-related quality of life (HRQoL); and (3) explore the acceptability of and satisfaction with the ICBT program among participants. METHODS: Patients with MDD were enrolled and randomized to the ICBT group or the waiting-list control (WLC) group. The ICBT group received ICBT delivered through a WeChat mini-program with general support by nonspecialists. Participants in the 2 groups were self-evaluated online at baseline and posttreatment for changes in the primary outcome (ie, depressive symptoms) and secondary outcomes (ie, anxiety symptoms, nonspecific psychological distress, general self-efficacy, depression stigma, social functional impairment, and HRQoL). Changes in outcomes were measured by changes in overall scores on respective scales, and response and remission rates were calculated based on depressive symptoms. The acceptability of and satisfaction with the ICBT program were measured by treatment adherence and participants' feelings (ie, modules seriously completed, perceived benefit, and satisfaction). RESULTS: We included 40 patients who were randomly assigned to the ICBT group and 44 who were assigned to the WLC group. Compared with the WLC group, the ICBT group had fewer depressive symptoms, fewer anxiety symptoms, less nonspecific psychological distress, and greater general self-efficacy. Moreover, the ICBT group had higher response (18/31, 58%) and remission rates (17/31, 55%). The adherence rate in the ICBT group was 78% (31/40), and the majority of participants who completed all ICBT modules were satisfied with the ICBT program. CONCLUSIONS: ICBT demonstrated greater improvements in depressive symptoms, anxiety symptoms, nonspecific psychological distress, and general self-efficacy among selected patients with MDD in comparison with the findings in waiting-list controls. The ICBT program in this study had good acceptability and satisfaction among participants. TRIAL REGISTRATION: Chinese Clinical Trial Registry (ChiCTR2100046425); https://tinyurl.com/bdcrj4zv.

Variation in facial hair is one of the most conspicuous features of facial appearance, particularly in South Asia and Middle East countries. A genome-wide association study in Latin Americans has identified multiple genetic variants at distinct loci being associated with facial hair traits including eyebrow thickness, beard thickness, and monobrow. In this pilot study, we have evaluated 16 SNPs associated with facial hair traits in 58 male individuals from the Punjabi population of Pakistan. In our sample, rs365060 in EDAR and rs12597422 in FTO showed significant association with monobrow, rs6684877 in MACF1 showed significant association with eyebrow thickness, and two SNPs in LOC105379031 (rs9654415 and rs7702331) showed significant association with beard thickness. Our results also suggest that genetic association may vary between ethnic groups and geographic regions. Although more data are needed to validate our results, our findings are of value in forensic molecular photofitting research in Pakistan.

Background & Objective: COVID-19 vaccine has become available within a record time but mere availability will not control the pandemic. High vaccine acceptance is required. The objective was to determine COVID-19 vaccine acceptance and its associated factors among Pakistani population. Methods: An online survey using google form, was conducted from January 31st to February 9th, 2021 before the start of the mass vaccination in Pakistan. The questionnaire had questions about demographics plus vaccine hesitancy. We received a total of 1156 responses. Data was analyzed using STATA version 14. We employed descriptive statistics and chi square test. Result: A total of 1156 responses were received. 65% were male and 35% female. Only 6% were uneducated. Thirty percent had tested positive for COVID-19 earlier. Forty-six percent of the respondents would take (acceptance) a vaccine if available. Forty-eight percent and 45% were confident in using USA/UK and Chinese vaccine respectively. Gender and marital status was statistically significantly associated with vaccine acceptance. Concerns about the side effects were 55% while for efficacy it was 69%. Twenty-three percent were concerned about the permissibility of the vaccine on religious grounds. Conclusion: Gender and marital status was significantly associated with vaccine acceptance. Forty-six percent respondents were willing to take the vaccine. Among the vaccine hesitant group, respondents were worried about the side effects, safety and religious permissibility of vaccine. Policy makers and all the relevant stakeholders should consider low vaccine acceptance as a major bottleneck and should devise strategies to address this major issue in the fight against COVID-19.
RESUMO
INTRODUCTION: Advances in diagnostic and treatment modalities for high grade bone sarcomas (HGBS) of lower extremity (LE) have enabled limb salvage resections as a feasible first-line surgical option. However, amputations are still performed. Impact of amputation on survival and predictive factors for amputation and the stage at presentation for HGBS of LE remain unknown. METHODS: National Cancer Database was used to extract 5781 cases of high-grade bone sarcoma of the LE from 2004 to 2017. Kaplan-Meier and Cox regression were used to determine the impact of amputation on survival. Chi square test and logistic regression were used to assess the correlation of predictive factors with amputation and stage at presentation. RESULTS: Amputation [hazard ratio (HR) 1.516; 95% confidence interval (CI) 1.259-1.826; p < 0.001] and advanced stage (HR 0.248; 95% CI 0.176-0.351; p < 0.001) were independent predictors of poor overall survival. The impact of amputation on survival was most pronounced for pediatric and adolescents and young adults (AYA) age groups (18% decrease in 10-year survival). Amputation was more likely to be performed among those with nonprivate insurance (HR 1.736; 95% CI 1.191-2.531; p = 0.004), a finding that was mirrored for advanced stage at presentation (HR 0.611; 95% CI 0.414-0.902; p = 0.013). DISCUSSION: Amputation is an independent predictor of poor outcomes among patients with HGBS of LE. The impact of amputation on survival is the highest for the pediatric and AYA age group. Nonprivate insurance is associated with increased likelihood of amputation and an advanced stage at presentation among patients with high-grade bone sarcoma of the LE. This is the largest study highlighting insurance-related disparities in this cohort.
RESUMO
BACKGROUND: We have analyzed sex, race/ethnicity or socioeconomic disparities in the incidence of metastatic bone disease (MBD). METHODS: Patients with the diagnosis of MBD at presentation for five most common primary anatomical sites was extracted from Surveillance, Epidemiology, and End Results Census tract-level dataset. Mean incidence of MBD for different sex, racial/ethnic and socioeconomic groups were compared. RESULTS: The five most common anatomical sites with MBD at presentation include "lung: (n = 59 739), "prostate" (n = 19 732), "breast" (n = 16 244), "renal" (n = 7718) and "colon" (n = 3068). There was an increase in incidence of MBD among cancers originating from prostate (annual percentage change [APC] 4.94), renal (APC 2.55), and colon (APC 3.21) (p < 0.05 for all). Non-Hispanic Blacks had higher incidence of MBD for prostate and breast primary sites (p < 0.001). Non-Hispanic American Indian Alaskan Native had higher incidence of MBD for cancers originating from renal (p < 0.001) and colon (p = 0.049). A higher incidence of MBD was seen in lower socioeconomic status (SES) groups for the selected sites (p < 0.001). CONCLUSIONS: These findings suggest that there are multiple sex-related, racial/ethnic and SES disparities in the incidence of MBD from the 5 most common primary sites. Higher incidence seen among lower SES suggests delay in diagnosis and limited access to screening modalities.

PURPOSE: The ideal local treatment modality for pelvic and sacral Ewing sarcoma (EWS) is controversial. METHODS: We present the data from the American College of Surgeon's National Cancer Database (NCDB) and the National Cancer Institute's Surveillance, Epidemiology and End Result (SEER) database to investigate the impact of local treatment modalities on survival for nonmetastatic pelvic and sacral Ewing sarcoma. Local treatment includes "surgery," "radiation," and a combination of "surgery and radiation." RESULTS: A total of 235 cases from SEER and 285 cases from NCDB were analyzed. Patients with "localized" stage (intraosseous) in the SEER database did not show any statistically significant difference in the disease-specific survival (DSS) for any of the local treatment modalities. Similar findings were observed for overall survival among patients with American Joint Committee on Cancer (AJCC) stage II and III in the NCDB database. However, patients with nonmetastatic disease, particularly regional disease (extraosseous), showed improved DSS with surgery only, in the SEER. CONCLUSION: We found similar levels of efficacy for different treatment modalities for patients with intraosseous and AJCC II and III pelvic and sacral EWS. "Radiotherapy" is the most common local treatment modality employed in the United States. A prospective, randomized controlled trial with a direct head-to-head comparison is needed for a definitive conclusion.

BACKGROUND: Postpartum depression (PPD) is a severe, debilitating mood disorder with consequences for both mothers and children, highlighting the need for rapid-acting and effective treatments for PPD. The aim of this narrative review is to synthesize the available literature on the administration of ketamine for PPD and propose ketamine as a viable and advantageous treatment. METHODS: A search was conducted on MEDLINE/PubMed, PsycInfo, and Embase databases from inception to October 10, 2021 for preclinical studies, interventional studies (ie, open-label and randomized controlled trials), as well as systematic reviews and meta-analyses evaluating the use of ketamine in postpartum populations. Completed and ongoing clinical trials were identified on ClinicalTrials.gov. RESULTS: Four clinical trials were identified. Results from this review support additional investigation into ketamine as a potential treatment for PPD. CONCLUSIONS: Ketamine may be a favorable option for treating PPD due to its antidepressive and analgesic effects, short infusion time, and rapid clearance from the maternal bloodstream. However, there is insufficient evidence to support its use in this population, underscoring the importance of additional clinical research investigating ketamine for PPD.

PURPOSE OF REVIEW: Lumateperone (LUM) is the U.S. Food and Drug Administration approved atypical antipsychotic agent for adults with schizophrenia (SCZ) and bipolar depression (for both bipolar I and bipolar II disorder as as monotherapy or as adjunctive treatment to lithium or valproate). LUM simultaneously modulates serotonin, dopamine, and glutamate neurotransmission. The foregoing pleiotropic mechanism of action is predictive of therapeutic benefits across multiple domains of psychopathology in SCZ (i.e., positive, negative, cognitive, and prosocial symptoms). Herein, the overarching aim is to synthesize the extant literature reporting on the efficacy, safety, and tolerability of LUM in adults with SCZ. RECENT FINDINGS: Four clinical studies (i.e., three RCTs and one open-label trial) were included in this synthesis. Overall, LUM significantly reduced the severity of SCZ compared with placebo. The open label study provided the real-world effectiveness of shifting stable patients with SCZ to LUM from other atypical antipsychotics. With respect to safety and tolerability profile, LUM demonstrated placebo-level rates of weight gain, metabolic shift, prolactin elevation, extrapyramidal side effects (EPS), and akathisia across short term trials (i.e., 4-6 weeks). Taken together, our results indicate that LUM significantly improves symptoms severity in adults with SCZ. LUM also exhibits a favorable tolerability and safety profile with placebo level rates of weight gain, metabolic disruption, akathisia, extrapyramidal side effects (excluding akathisia), and prolactin elevation. Lumateperone should be conceptualized as a first-line treatment strategy for adults with SCZ.

BACKGROUND: Primary sarcomas originating from the mobile spine portends a particularly sinister outcome. Rarity of the disease process has resulted in inconsistent data due to small sample size and heterogeneity in patient selection and analytics. METHODS: Surveillance, Epidemiology and End Result (SEER) database from 1975 to 2017 was queried to report incidence and survival data in 712 patients in the United States. Kaplan-Meier and Cox Regression were used to determine the prognostic factors affecting survival. RESULTS: Incidence of spinal sarcoma was 0.019 per 100,000 persons in 2017 and has not significantly changed since 2000 (p > 0.05). Disease-specific 5-year survival for the entire cohort was 57%. Osteosarcoma has the worst 5-year survival (39%) and chondrosarcoma has the best 5-year survival (69%). Independent predictors of survival for the entire cohort included age, grade, and stage. Stage was an independent predictor of survival for every histologic subtype. Additional predictors of survival for spinal osteosarcoma, Ewing sarcoma, and chondrosarcoma included age, size, and grade, respectively. CONCLUSIONS: The current study is an analysis of a population-based registry reporting incidence survival data for patients with sarcoma of mobile vertebral column. Survival and prognostic factors vary by histologic subtypes. There is lack of improvement in survival over the last three decades.

BACKGROUND: Primary sarcomas originating from the bones of hand and wrist are rare but carry a significant burden of morbidity. METHODS: National Cancer Institute's Surveillance, Epidemiology and End Result database from 1975 to 2017 was queried to report incidence and survival data in 237 patients in the United States. Kaplan-Meier and Cox regression were used to determine the prognostic factors affecting survival. χ2 test was used to assess the correlation. RESULTS: Incidence of hand and wrist sarcoma was 0.017 per 100 000 persons in 2017 and has not significantly changed since 1975 (p > 0.05). Disease-specific 5-year and 10-year survival for the entire cohort was 90% and 84%, respectively. On multivariate analysis race "others," histology other than "osteosarcoma," "undifferentiated" grade, and size "≥6 cm" were predictors of worse disease-specific survival. Cross-tabulation of race with other significant prognostic factors on univariate analysis revealed a significant correlation of race with every other significant prognostic factor except for grade. CONCLUSIONS: The current study is an analysis of a population-based registry reporting incidence and survival data for patients with sarcoma of hand and wrist. Independent prognostic factors include race, histology, grade, and size. There is a lack of improvement in survival over the last four decades.

PURPOSE: Neoplasms originating from the "small bones of the lower limb and the overlapping joints" are rare but portend a serious prognosis. Current study utilizes a population-based registry in the United States to characterize the malignancies of the foot. METHODS: National Cancer Institute's Surveillance, Epidemiology and End Result database from 1975 to 2017 was queried to report incidence and survival data in 514 patients in the Uited States. Kaplan-Meier and Cox Regression were used to determine the prognostic factors affecting survival. Chi square test was used to assess the correlation. RESULTS: Hematological malignancies constituted 14.8% of the entire cohort. Incidence of the foot neoplasms was 0.024 per 100 000 persons in 2017 and has not significantly changed since 1975 (p > 0.05). Disease-specific-5-year survival for the entire cohort was 73%. On multivariate analysis younger age groups, "localized" stage and extent of surgical resection were predictors of improved outcomes. A significant correlation was found between amputation with male sex and Hispanic ethnicity. CONCLUSIONS: The current study analyzes data from population-based registry reporting incidence and survival data for patients with neoplasms of the foot. Independent prognostic factors include age, stage and extent of surgical resection. Amputation was found to be associated with male sex and Hispanic ethnicity.

BACKGROUND: The benefits of oversewing the staple lines during laparoscopic sleeve gastrectomy have been controversial. No study examined the benefit of oversewing the staple lines in robotic sleeve gastrectomy (RSG). This retrospective study aims to examine the difference in immediate postoperative complications, readmissions, reoperations, and emergency room visits between RSG patients with and without oversewn staple lines at a single, large-volume, bariatric center. METHODS: A retrospective chart review was conducted on 623 patients who underwent RSG between November 1, 2017, and November 1, 2019. Of these, 316 had their staple line oversewn between November 1, 2017, and November 12, 2018, and 307 did not have their staple line oversewn between November 13, 2018, and November 1, 2019. RESULTS: A total of 623 patients underwent RSG, of which 50.7% (n = 316) had their staple line oversewn. The mean length of hospital stay was similar between the two groups. However, the mean operative time was significantly longer in the "oversew" group than "no oversew" group by 7.4 minutes (p < 0.001). Readmission, reoperation, and intervention rates during the 30-day postoperative period were similar between the two groups. However, the percentage of patients requiring outpatient emergency room visits during the 30 days after RSG was significantly higher in the "oversew" group than that of the "no oversew" group. CONCLUSIONS: No significant difference in major complications was found between RSG patients with and without oversewn staple lines. Oversewing of the staple line may be associated with increased emergency room visits.

In this paper, the steady electrically conducting hybrid nanofluid (CuO-Cu/blood) laminar-mixed convection incompressible flow at the stagnation-point with viscous and gyrotactic microorganisms is considered. Additionally, hybrid nanofluid flow over a horizontal porous stretching sheet along with an induced magnetic field and external magnetic field effectsthat can be used in biomedical fields, such as in drug delivery and the flow dynamics of the microcirculatory system. This investigation can also deliver a perfect view about the mass and heat transfer behavior of blood flow in a circulatory system and various hyperthermia treatments such as the treatment of cancer. The simple partial differential equations (PDEs) are converted into a series of dimensional ordinary differential equations (ODEs), which are determined using appropriate similarities variables (HAM). The influence of the suction or injection parameter, mixed convection, Prandtl number, buoyancy ratio parameter, permeability parameter, magnetic parameter, reciprocal magnetic prandtl number, bioconvection Rayleigh number, coupled stress parameter, thermophoretic parameter, Schmidt number, inertial parameter, heat source parameter, and Brownian motion parameter on the concentration, motile microorganisms, velocity, and temperature is outlined, and we study the physical importance of the present problem graphically.
