Abstract

Background: Evidence is mounting across diverse datasets and scientific techniques implicating immune dysregulation in poor outcomes of high grade and/or triple negative breast cancers. A multimodal strategy to stimulate the immune system could be an effective therapeutic approach for breast cancer. CpG oligodeoxynucleotides are single-stranded DNA that stimulate dendritic cells and B cells by binding to Toll-like receptor 9 (TLR9). OX40 (CD134) is predominantly expressed on activated T cells and the binding of OX40 with an agonistic antibody (anti-OX40) leads to the proliferation and survival of T cells. Agonistic anti-OX40 antibodies can also reverse the suppressive effects of Treg cells. A third avenue is to target Cytotoxic T lymphocyte associated antigen (CTLA4), which plays a negative regulatory role in T cell activation and is also constitutively expressed on Treg cells. Blocking CTLA4 with an antagonistic antibody (anti-CTLA4) has been shown to enhance anti-tumor responses. In this study, we tested the combination of intratumoral (IT) CpG with systemic anti-OX40 plus anti-CTLA4 in a mouse model of triple negative breast cancer. Methods: 4T1, an aggressive, triple-negative mammary carcinoma, was implanted orthotopically into syngeneic BALB/C mice. Treatment was initiated when tumors were 0.5 cm in the largest dimension. Mice were divided into 8 groups. Various combinations of PBS control, CpG, taxol, and anti-OX40+anti-CTLA4 mAbs were tested (Tables 1 and 2). CpG, 100 µg, was injected IT for 5 consecutive days (days 1-5); Taxol, 16 mg/kg, was administered IP on day 1; anti-OX40 (400 µg) and anti-CTLA4 (100 µg) were given IP on days 1 and 5. Mice were sacrificed once tumors became ulcerated or reached a diameter >2 cm. Results: As shown in Table 1, CpG alone, taxol alone, or the anti-OX40 + anti-CTLA4 combination each delayed the growth of established 4T1 tumors when compared to the untreated control group. However, the majority of the mice (except one in CpG treated group) died from tumor progression. The combination of CpG + anti-OX40 + anti-CTLA4 had the best anti-tumor effects, with 4 out of 5 mice having demonstrated complete regression of their tumors (Table 2). The addition of taxol to the combination of CpG + anti-OX40 + anti-CTLA4 did not improve the anti-tumor effect, and while there was a substantial delay in growth, only one animal achieved a complete regression. Conclusion: Our study demonstrated that the combination of IT CpG with systemic anti-OX40 + anti-CTLA4 mAbs can cure mice with established triple negative breast tumors, supporting the possibilities of applying immune modulation approach in human triple negative tumors. Studies are on-going to further dissect the immunological mechanisms involved. [ABSTRACT FROM AUTHOR]

212. Prolonged survival of baboon renal allografts using idarubicin‐conjugated anti‐CD4 monoclonal antibodies

Author

Abstract

AbstractTolerance to organ allografts in rodents and pigs can be easily achieved. However, tolerance induction in a large primate model has been more elusive. In this study, we have used an anti‐CD4, murine monoclonal antibody as a carrier for the cytotoxic drug idarubicin (IDA) to delete or inactivate alloreactive T‐cells responding to a renal allograft in a baboon transplant model. Fourteen Chacma baboons weighing between 15‐25 kg received heterotopic renal allografts. Recipient and donor pairs were selected on the basis of ABO compatibility. Seven animals were given no immunosuppression and served as the control group. The remaining 7 animals received anti‐CD4 IDA. The first 2 animals in this group received 2 mg IVI intraoperatively and three doses at 48‐h intervals thereafter. The last 5 animals received a larger dose of 1 mg/kg, starting 24 h pre‐operatively and again on postoperative days 2 and 5. The untreated animals promptly rejected their allografts with a mean survival of 10 days. The survival of the 2 animals treated with 2 mg anti‐CD4 IDA was 7 days each. However, the animals treated with 1 mg/kg anti‐CD4 IDA survived 7, 18, 20, 40 and > 40 days. Peritransplant administration of anti‐CD4 IDA prolonged renal allograft survival in a large primate model. This unique immunoconjugate has the potential of tolerance induction.

213. Withdrawal of cyclosporine in renal transplant recipients with acute tubular necrosis improves renal function

Author

Kahn, D., Botha, J.F., Pascoe, M.D., Pontin, A.R., Halkett, J., and Tandon, V.

Abstract

AbstractIn this study, patients with acute tubular necrosis (ATN) after renal transplantation were prospectively randomized to either conventional immunosuppression or withdrawal of cyclosporine and replacement with anti‐thymocyte globulin (ATG). The patients treated with cyclosporine withdrawal and ATG had a significantly shorter duration of ATN (8.9 ± 1.5 vs 10.8 ± 1.4 days; P< 0.05) and better renal function (mean serum creatinine on day 5 postoperatively: 740 ± 49 vs 918 ± 73 μmol/l; P< 0.05). The incidence of acute rejection was lower in the patients with cyclosporine withdrawal and ATG. In conclusion, cyclosporine is toxic to the renal allograft with ATN, and withdrawal of cyclosporine shortens the duration of ATN and improves renal function.

Abstract

It is a well-known fact that angiotensin converting enzyme inhibitors (ACEI) alone can control blood pressure in approximately fifty per cent of the patients with mild to moderate hypertension and many consider them first line drugs for blood pressure. Ninety per cent of patients with mild to moderate hypertension can be controlled by a combination of an ACEI with a Ca positive 2 channel blocker, beta-adrenergic receptor blocker or a diuretic. But in five to twenty per cent of patients, ACEI can induce bothersome dry cough which usually develops between the 1st week and 6 months after initiation of therapy. Cessation of therapy is needed sometimes to control the dry cough.

Abstract

Abstract: The alcoholic extract of Lysimachia ramosa Wall (Primulaceae) was tested in vitro against helminth parasites, Fasciolopsis buski and Ascaris suum, from porcine hosts and Raillietina echinobothrida from domestic fowl. The live adult parasites, collected from a freshly autopsied host, were exposed to different concentrations (5–50mg) of the test plant extract in physiological phosphate-buffered saline (PBS) having 0.1% dimethyl sulphoxide (DMSO) at 37±1°C. The treated parasites revealed complete inactivation and flaccid paralysis that was followed by death at varying periods of time. A dose-dependent loss of motility and mortality was observed in all the treated parasites. Scanning electron microscopic observations revealed conspicuous deformity of the surface architecture in all the parasites exposed to the test plant extract. The general tegument in F. buski showed shrinkage and loss of scale-like spines; proglottides all along the strobilar length in R. echinobothrida appeared shrunken and deformed and the cuticular surface of A. suum appeared disorganised, having lost transverse striations. The botanicals of the test plant seem to be effective against all the three types of helminth parasites. [Copyright &y& Elsevier]

Abstract

Ethnopharmacological relevance: The stem bark of Acacia oxyphylla Graham ex Bentham is used as an anthelmintic by the natives of Mizoram (North-East India). Aim of the study: The present study was performed to evaluate whether or not the plant-derived components caused any ultrastructural changes in the tegumental interface of the parasite. Materials and methods: The test parasite Raillietina echinobothrida, the cestode of domestic fowl, was exposed to the ethanolic crude extract and acetone fraction of stem bark of Acacia oxyphylla for varying concentrations and time duration and processed for transmission electron microscopy as soon as paralysis set in the treated parasites. Results: Treatment with crude alcoholic extract and its acetone fraction revealed complete inactivation and flaccid paralysis of the cestode, which was soon followed by death. The treated parasites also exhibited intense vacuolization of the tegumental layers along with complete disorganization and/or erosion of microtriches. Conclusions: Considerable structural alterations in the treated parasites are suggestive of an efficient vermicidal activity of the Acacia oxyphylla stem bark-derived botanicals against cestodes.

Abstract

Drug development suffers from a lack of predictive and human-relevant in vitro models. Organ-on-chip (OOC) technology provides advanced culture capabilities to generate physiologically appropriate, human-based tissue in vitro, therefore providing a route to a predictive in vitro model. However, OOC technologies are often created at the expense of throughput, industry-standard form factors, and compatibility with state-of-the-art data collection tools. Here we present an OOC platform with advanced culture capabilities supporting a variety of human tissue models including liver, vascular, gastrointestinal, and kidney. The platform has 96 devices per industry standard plate and compatibility with contemporary high-throughput data collection tools. Specifically, we demonstrate programmable flow control over two physiologically relevant flow regimes: perfusion flow that enhances hepatic tissue function and high-shear stress flow that aligns endothelial monolayers. In addition, we integrate electrical sensors, demonstrating quantification of barrier function of primary gut colon tissue in real-time. We utilize optical access to the tissues to directly quantify renal active transport and oxygen consumption via integrated oxygen sensors. Finally, we leverage the compatibility and throughput of the platform to screen all 96 devices using high content screening (HCS) and evaluate gene expression using RNA sequencing (RNA-seq). By combining these capabilities in one platform, physiologically-relevant tissues can be generated and measured, accelerating optimization of an in vitro model, and ultimately increasing predictive accuracy of in vitro drug screening.

Abstract

Background: The contribution of thrombosis to the aetiology of perioperative myocardial infarction (MI) is uncertain. We used optical coherence tomography (OCT) to determine the presence of thrombus and plaque morphology in patients experiencing a perioperative MI and matched patients experiencing a non-operative MI using OCT.Methods: We conducted a single-centre, prospective, cohort study. Thirty patients experiencing a perioperative MI and 30 matched patients experiencing a non-operative MI, without ST elevation, underwent OCT to determine the presence of thrombus and culprit lesion plaque morphology. Angiography and OCT were performed a mean of 1.93(1.09) days and 1.53(0.68) days after the onset of perioperative and non-operative MI, respectively. OCT images were evaluated by an independent core laboratory without knowledge of whether the patient had suffered a perioperative or non-operative MI.Results: We identified thrombus at the culprit lesion in four of 30 patients (13.3%) who experienced a perioperative MI and in 20 of 30 patients (66.7%) who experienced a non-operative MI, P<0.01. The only non-culprit lesion with thrombus was in a perioperative MI patient who also had a culprit lesion thrombus. Perioperative and non-operative MI culprit lesions demonstrated fibroatheroma in 18 patients (60.0%) us 20 patients (66.7%), respectively (P=0.52) and thin cap fibroatheroma in one patient (3.3%) us five patients (16.7%), respectively (P=0.11). One perioperative MI patient (3.3%) suffered a cardiac death and no non-operative MI patient died during the 30-day follow-up.Conclusions: Thrombosis was less common in perioperative than non-operative MI, despite similar underlying plaque morphology.

Abstract

BACKGROUND: The extent to which health care systems have adapted to the COVID-19 pandemic to provide necessary cardiac diagnostic services is unknown.OBJECTIVES: The aim of this study was to determine the impact of the pandemic on cardiac testing practices, volumes and types of diagnostic services, and perceived psychological stress to health care providers worldwide.METHODS: The International Atomic Energy Agency conducted a worldwide survey assessing alterations from baseline in cardiovascular diagnostic care at the pandemic's onset and 1 year later. Multivariable regression was used to determine factors associated with procedure volume recovery.RESULTS: Surveys were submitted from 669 centers in 107 countries. Worldwide reduction in cardiac procedure volumes of 64% from March 2019 to April 2020 recovered by April 2021 in high- and upper middle-income countries (recovery rates of 108% and 99%) but remained depressed in lower middle- and low-income countries (46% and 30% recovery). Although stress testing was used 12% less frequently in 2021 than in 2019, coronary computed tomographic angiography was used 14% more, a trend also seen for other advanced cardiac imaging modalities (positron emission tomography and magnetic resonance; 22%-25% increases). Pandemic-related psychological stress was estimated to have affected nearly 40% of staff, impacting patient care at 78% of sites. In multivariable regression, only lower-income status and physicians' psychological stress were significant in predicting recovery of cardiac testing.CONCLUSIONS: Cardiac diagnostic testing has yet to recover to prepandemic levels in lower-income countries. Worldwide, the decrease in standard stress testing is offset by greater use of advanced cardiac imaging modalities. Pandemic-related psychological stress among providers is widespread and associated with poor recovery of cardiac testing.

Abstract

Background For patients undergoing noncardiac surgery, bleeding and hypotension are frequent and associated with increased mortality and cardiovascular complications. Tranexamic acid (TXA) is an antifibrinolytic agent with the potential to reduce surgical bleeding; however, there is uncertainty about its efficacy and safety in noncardiac surgery. Although usual perioperative care is commonly consistent with a hypertension-avoidance strategy (i.e., most patients continue their antihypertensive medications throughout the perioperative period and intraoperative mean arterial pressures of 60 mmHg are commonly accepted), a hypotension-avoidance strategy may improve perioperative outcomes. Methods The PeriOperative Ischemic Evaluation (POISE)-3 Trial is a large international randomized controlled trial designed to determine if TXA is superior to placebo for the composite outcome of life-threatening, major, and critical organ bleeding, and non-inferior to placebo for the occurrence of major arterial and venous thrombotic events, at 30 days after randomization. Using a partial factorial design, POISE-3 will additionally determine the effect of a hypotension-avoidance strategy versus a hypertension-avoidance strategy on the risk of major cardiovascular events, at 30 days after randomization. The target sample size is 10,000 participants. Patients ≥45 years of age undergoing noncardiac surgery, with or at risk of cardiovascular and bleeding complications, are randomized to receive a TXA 1 g intravenous bolus or matching placebo at the start and at the end of surgery. Patients, health care providers, data collectors, outcome adjudicators, and investigators are blinded to the treatment allocation. Patients on ≥ 1 chronic antihypertensive medication are also randomized to either of the two blood pressure management strategies, which differ in the management of patient antihypertensive medications on the morning of surgery and on the first 2 days after surgery, and in the target mean arterial pressure during surgery. Outcome adjudicators are blinded to the blood pressure treatment allocation. Patients are followed up at 30 days and 1 year after randomization. Discussion Bleeding and hypotension in noncardiac surgery are common and have a substantial impact on patient prognosis. The POISE-3 trial will evaluate two interventions to determine their impact on bleeding, cardiovascular complications, and mortality. Trial registration ClinicalTrials.gov NCT03505723.

Abstract

Opisthorchiasis is a public health problem in South-East Asian countries and Eastern Europe. The infection implicates mainly two species of Opisthorchis, namely O. viverrini and O. felineus, that occur mostly in fish-eating mammals and humans, although there are rare reports of human cases involving two other species, O. noverca and O. guayaquilensis. Opisthorchis noverca has been reported frequently in dogs and pigs from the Indian subcontinent, with rare reports from cattle and human subjects. With a view to supplementing morphology-based identification of this species, the present study aimed to provide molecular characterization of O. noverca, using rDNA internal transcribed spacer 2 (ITS2) and mitochondrial cytochrome oxidase I (mt COI) markers so as to determine its genetic correlation with other species of Opisthorchiidae, and also to generate a taxon-specific molecular marker based on the ITS2 region. The phylogenetic relationship between O. noverca and other species of the genus was determined using molecular sequence data. To strengthen the result, secondary structure sequence analyses of ITS2 with hemi-compensatory base changes (hCBCs), and amino acid sequence analyses, were also evaluated. Our results confirm that O. noverca is a distinct and valid species. [ABSTRACT FROM AUTHOR]

Abstract

Background: The coronavirus disease-2019 (COVID-19) pandemic significantly affected management of cardiovascular disease around the world. The effect of the pandemic on volume of cardiovascular diagnostic procedures is not known. Objectives: This study sought to evaluate the effects of the early phase of the COVID-19 pandemic on cardiovascular diagnostic procedures and safety practices in Asia. Methods: The International Atomic Energy Agency conducted a worldwide survey to assess changes in cardiovascular procedure volume and safety practices caused by COVID-19. Testing volumes were reported for March 2020 and April 2020 and were compared to those from March 2019. Data from 180 centers across 33 Asian countries were grouped into 4 subregions for comparison. Results: Procedure volumes decreased by 47% from March 2019 to March 2020, showing recovery from March 2020 to April 2020 in Eastern Asia, particularly in China. The majority of centers cancelled outpatient activities and increased time per study. Practice changes included implementing physical distancing and restricting visitors. Although COVID testing was not commonly performed, it was conducted in one-third of facilities in Eastern Asia. The most severe reductions in procedure volumes were observed in lower-income countries, where volumes decreased 81% from March 2019 to April 2020. Conclusions: The COVID-19 pandemic in Asia caused significant reductions in cardiovascular diagnostic procedures, particularly in low-income countries. Further studies on effects of COVID-19 on cardiovascular outcomes and changes in care delivery are warranted.

Abstract

OBJECTIVE To assess the ability of artificial neural networks (ANNs) to predict optimum renal stone fragmentation in patients being managed by extracorporeal shock wave lithotripsy (ESWL). PATIENTS AND METHODS The study included 82 patients with renal stones who were being treated by ESWL. Data (input and output values) from 60 patients in whom there was optimum fragmentation of stones by ESWL were used for training the ANN. These data mainly included the 24-h urinary variables, the radiological features of the stone disease and the ESWL settings used. The predictability of the trained ANN was tested on 22 subsequent patients, by supplying the input variables of the 22 patients into the trained ANN and recording the output values (predicted values). After subjecting these patients to ESWL, the actual results (observed values) were recorded. The predicted and the observed values were then compared. RESULTS In the 22 patients in whom predictability was tested, the trained ANN predicted optimum fragmentation at ≤ 13 000 shocks/stone (as per study protocol) in 17 and optimum fragmentation at> 13 000 shocks/stone in the other five. In the 17 patients (test set) where the trained ANN had predicted optimum fragmentation at ≤ 13 000 shocks/stone, the optimum fragmentation was at that value, although the predicted and observed values were not identical. The overall correlation between the predicted and the observed values was 75.5% (correlation coefficient 0.7547) in these 17 patients. Of the other five patients, none had optimum fragmentation at < 13 000 shocks/stone, as predicted by the trained ANN, giving complete accuracy for this factor. CONCLUSION This was a pilot study, i.e. an initial attempt to use an ANN in this regard, and although there were few patients, such that it is not possible to make final recommendations, the overall predictability was ≈ 75%. An encouraging outcome of the study was that the trained ANN identified patients unlikely to benefit from ESWL. Using a larger dataset and identifying more significant variables, while eliminating inputs with a negative effect, the efficiency and utility of this ANN can probably be enhanced and in future it might be possible to predict stone fragmentation with reasonable accuracy.

Abstract

Objective: To evaluate polymethyl methacrylate hydrogel microspheres (HMs) as an embolization material in the management of hypervascular craniofacial and spinal lesions.Material and Methods: Sixty-nine patients with vascular lesions of the craniofacial and spinal regions underwent embolization with HM. The pathologies included craniofacial tumours (n=38), cranial arteriovenous malformations (AVMs) (n=7), dural AVM (n=1), cavernous carotid fistula (n=1), spinal tumours (n=7), spinal AVMs (n=6), orbital lesions (n=4) and scalp AVMs (n=5). Surgery was done in 56 patients. The blood loss at surgery, tumour shrinkage, surgical cleavage and ease of removal of tumour was noted from the records. Histopathology was available in 39 patients. A follow-up of 3 months to 6 years was available in 13 patients in whom embolization was the sole treatment. Surgical and histopathological findings were correlated with angio-embolization findings.Results: HMs were easy to inject through the microcatheter with good control. Good devascularization was obtained in 61 patients and partial in 8 patients. Two patients developed complications due to presence of anastomoses between intra- and extracranial circulation and 1 patient due to tumor swelling. Histopathology showed presence of HMs in all the lesions, with minimal inflammatory reaction in 2 patients. Patients with spinal lesions treated with embolization only stabilised in neurologic deficits.Conclusion: HMs are highly suitable as embolization agents in the management of craniofacial and spinal hypervascular lesions.

Abstract

Sodium valproate is used for the management of seizures, status epilepticus, chronic pain syndrome, bipolar, and other affective disorders. Even with an acceptable safety profile, severe idiosyncratic reactions can occur with valproate use. A rare, serious, and life-threatening side effect of valproate is valproate-induced hyperammonemic encephalopathy (VHE). We intend to analyze the clinical presentation, diagnosis, treatment options, and outcome of VHE in neurosurgical patients and review the pertinent literature on this rare sequelae. We retrospectively reviewed patients who developed VHE following valproate use, either for the treatment of epilepsy or for seizure prophylaxis in our centre. We analyzed the demographic details, clinical presentation, diagnosis, management, and outcomes. A total of four patients with a mean age of 26.3 ± 5.1 (range 19 - 32 years). Valproate was prescribed for primary seizure prophylaxis in 2 patients (50%). The commonest etiology for valproate prescription was for brain tumors (3, 75%) followed by drug-refractory epilepsy (DRE) (1, 25%). None of the patients were documented to have urea cycle disorder. The mean daily prescribed dosage of valproate was 1250 ± 559 mg and the mean duration of administration was 13 ± 13.3 months (range 4 months - 36 months). The mean serum NH3 level was 136,5 ± 44.2 µmol/L (range 107 - 212.8) and all patients (4, 100%) had hyperammonemia with a mortality rate of 50% (2 patients). The hyperammonemia was treated by stopping the valproate use (4, 100%) and dialysis (2, 50%). Normalization of ammonia levels led to clinical improvement in 50% (2 patients). Neurological deterioration in the postoperative period is a diagnostic challenge. VHE is a rare and life-threatening sequelae of Valproate-associated Hyperammonemia (VAH) in neurosurgical patients. A high index of suspicion is required due to its ambiguous presentation. Early diagnosis and prompt treatment can change the course of this life-threatening sequelae., (© 2024.

Abstract

Astroblastoma, a unique entity of glial tumor, predominantly occur in young women with distinctive MN1 rearrangement, Given its limited documentation in existing literature, we report eight cases of astroblastoma, detailing their clinical, radiological, and histopathological characteristics along with molecular analysis. We conducted a retrospective analysis of our neuropathology archive database spanning the past 8 years. We included all cases that underwent Magnetic Resonance Imaging (MRI), surgical resection, histopathological examination, molecular testing, and follow-up. Histopathological examination involving immunohistochemistry and Fluorescence In Situ Hybridization (FISH) was carried out for all cases. All tumors were found to be located in the supratentorial region (cerebral hemisphere). The median age of the group was 35.1 years, with a female-to-male ratio of 1.6:1. The most common clinical presentation was headache. Morphologically, all tumors exhibited astroblastic features with pseudorosettes and perivascular hyalinization. Immunohistochemistry consistently revealed positivity for EMA and variable immunoreactivity for GFAP, OLIG2, and D2-40. Fluorescence In Situ Hybridization (FISH) analysis conducted for all cases showed MN1 rearrangement in 7 cases. The mean follow-up period was 45 months (ranging from 12 to 105 months).

Abstract

Background: A glaring gender inequality persists in global neurosurgery, influenced by various factors, including the notion that female neurosurgeons have lower academic output. This study aims to compare the research output of female and male neurosurgeons at the leading academic institutions in India., Methods: The pertinent details regarding female neurosurgeons were collected from the Neurological Society of India (NSI) and Women In Neurosurgery (India) database. The institutes with at least five neurosurgery faculty recognised by the Medical Council of India (MCI) were included in the study. Various bibliometric parameters of male and female faculty at these academic centres were collected and compared using PubMed and Web of Science databases., Results: Among the 2643 neurosurgeons in NSI, 113 were females (4.27%). Out of 156 faculty members across eighteen academic institutions, only seven (4.7%) were female, with eleven institutions lacking female faculty. Female academic neurosurgeons had slightly higher h-index (9.57 vs. 9.56), citation per publication (8.82 vs. 8.54), and original article percentage (47.5 vs. 46.5) compared to males. They also had more citations per year (34.01 vs. 33.17), while males had more total publications (51.19 vs. 46.71) and citations (565.22 vs. 533.57), but these differences weren't statistically significant. Only 4.1% (327/7955) of neurosurgery research was contributed by females. Female neurosurgeons authored articles received 3735 citations (4.2%) out of 87,953 total citations., Conclusion: Female academic neurosurgeons in India exhibit comparable or superior academic output compared to their male counterparts, suggesting gender equality or even superiority in certain aspects of academic performance., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.

Abstract

Introduction: This study compares the effectiveness of virtual reality simulators (VRS) and a saw bone model for learning lumbar pedicle screw insertion (LPSI) in neurosurgery., Methods: A single-center, cross-sectional, randomized controlled laboratory investigation was conducted involving residents and fellows from a tertiary care referral hospital. Participants were divided into two groups (A and B). Group A performed 3 LPSI tasks: the first on a saw bone model, the second on VRS, and the third on another saw bone model. Group B completed 2 LPSI tasks: the first on a saw bone model and the second on another saw bone model. The accuracy of LPSI was evaluated through noncontrast computed tomography scans for the saw bone models, while the in-built application of VRS was utilized to check for accuracy of screw placement using the simulator., Results: The study included 38 participants (19 in each group). Group A participants showed reduced mean entry point error (0.11 mm, P 0.024), increased mean purchase length (4.66 cm, P 0.007), and no cortical breaches (P 0.031) when placing the second saw bone model screw. Similar improvements were observed among group A participants in PGY 1-3 while placing the second saw bone model screws., Conclusions: Virtual reality simulators (VRS) prove to be an invaluable tool for teaching complex neurosurgical skills, such as LPSI, to trainees. This technology investment can enhance the learning curve while maintaining patient safety., (Copyright © 2024. Published by Elsevier Inc.)

Abstract

Freshwater crabs ( Potamiscus manipuriensis ), commonly consumed as local delicacies by the native people in the state of Manipur, were found to harbour metacercariae of Microphallus sp. (Family Microphyllidae), which were morphologically different from metacercariae of Microphallus spp reported earlier from different regions. So, PCR-based molecular characterization of this metacercaria was done utilizing rDNA marker regions: larger subunit (LSU) or 28S (D1-D3 region) and inter-transcribed spacer 2 (ITS2). Sequence and phylogenetic analyses confirmed that the taxon under study belonged to family Microphyllidae of genus Microphallus ., Competing Interests: Conflict of interestThe authors declare that they have no conflict of interest., (© Indian Society for Parasitology 2024.

247. One-pot synthesis of tetrahydropyrimidinecarboxamides enabling in vitro anticancer activity: a combinative study with clinically relevant brain-penetrant drugs.

Author

Upadhyay DB, Nogales J, Mokariya JA, Vala RM, Tandon V, Banerjee S, and Patel HM

Abstract

In this study, we describe a one-pot three-component synthesis of bioactive tetrahydopyrimidinecarboxamide derivatives employing lanthanum triflate as a catalyst. Out of the synthesized compounds, 4f had the most potent anti-cancer activity and impeded cell cycle progression effectively. Anti-cancer bioactivity was observed in 4f against liver, breast, and lung cancers as well as primary patient-derived glioblastoma cell lines. Compound 4f effectively inhibited the 3D neurosphere formation in primary patient-derived glioma stem cells. Specifically, 4f exhibited synergistic cytotoxicity with the EGFR inhibitor that is the clinical epidermal growth factor receptor inhibitor osimertinib. 4f does not exhibit anti-kinase activity and is cytostatic in nature, and further work is needed to understand the true molecular target of 4f and its derivatives. Through our current work, we establish a promising tetrahydopyrimidinecarboxamide-based lead compound with anti-cancer activity, which may exhibit potent anti-cancer activity in combination with specific clinically relevant small molecule kinase inhibitors., Competing Interests: DBU, JN, RMV, SB, and HMP are named inventors on the patent no. 528662 awarded by the government of India on 18th March 2024 pertaining to these reported compounds.

Abstract

Remdesivir, a C-nucleotide prodrug binds to the viral RNA-dependent-RNA polymerase ( RdRp ) and inhibits the viral replication by terminating RNA transcription prematurely. It is reported in literature that interaction between the C-1'β-CN moiety of Remdesivir ( RDV ) and the Ser861 residue in RdRp enzyme, causes a delayed chain termination during the RNA replication process and is one of the important aspect of its mechanism of action. In the pursuance of increasing the biological activity of RDV and enhancing the SAR studies, against RNA viruses, we have designed its fourteen C1'β substituted analogs, 10 - 23 bearing 4/5-membered heterocyclic rings. The docking and 100 ns molecular dynamics (MD) simulations of 10 - 23 to the RdRp protein (PDB ID: 7L1F) revealed important interactions between 2',3'-diol, oxo group of phosphoramidate, nitrogen residues of heterocyclic rings of synthetic molecules with Arg555, Arg553, Ser759, Cys622, Asn691, Asp623 amino acid residues of protein. The docking score of 2-ethylbutyl ((S)-(((2R,3S,4R,5R)-5-(4-aminopyrrolo[2,1-f][1,2,4]triazin-7-yl)-3,4-dihydroxy-5-(1H-1,2,3-triazol-4-yl)tetrahydrofuran-2-yl)methoxy)(phenoxy)phosphoryl)-L-alaninate, 11 was found to be the higher than RDV among 14 new compounds i.e. -5.20 kcal/mol. Out of 3 compounds, 10 , 12 and 13 submitted for MD simulations and Molecular Mechanics Poisson-Boltzmann Surface Area (MMPBSA) analysis, trifluoro-oxadiazole derivative, 13 showed higher binding energy as compared to Remdesivir. The predicted ADMET properties of 14 compounds showed their potential for being drug candidates. The present study suggests that substitution at the C1'β position by 4/5-membered rings plays an important role in the interactions between nucleoside/tide and target protein., Competing Interests: The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Vibha Tandon reports financial support was provided by 10.13039/501100001843Science and Engineering Research Board.

Abstract

Bael is a fruit crop that is extensively distributed throughout South-East Asia and is underutilized in medicine. The potential applications of bael's therapeutic and nutritional qualities in diverse ethnic communities are enormous. This study focuses on evaluating the morpho-pomological and molecular characteristics, utilizing SSR markers, of 80 wild bael genotypes alongside the NB-5 and NB-9 cultivars, derived from the North Western plains of India. Based on the evaluated morpho-pomological features, substantial variations were found between all genotypes. The fruit's inner diameter and pulp weight varied from 4.41 to 11.54 cm and 34.63 to 786.41 g, respectively. Numerous variations in the genotypes were observed in the shell weight/fruit, fruit skull thickness and fruit yield/plant. The bael fruit mucilage's total soluble solids (TSS) and total sugar content varied from 40.10 to 49.60 o brix and 8.11 to 21.17%, respectively. Using ward cluster analysis, the genotypes were divided into two primary clusters. Among the bael genotypes, the population structure analysis identified three subpopulations. SSR markers are used to measure genetic variety; of the 27 polymorphic markers, 17 show allelic diversity between genotypes. Molecular genetic diversity analysis, on the other hand, highlighted the genotypes genetic distinctiveness by classifying them into three major clusters. These findings offer valuable insights into the rich diversity and intricate interactions among the bael genotypes under investigation, paving the way for more strategic future breeding and selection efforts to elevate the quality of this remarkable fruit., (© 2024.

Abstract

Background: During the COVID-19 pandemic, a multitude of surveys have analyzed the impact virus spreading on the everyday medical practice, including neurosurgery. However, none have examined the perceptions of neurosurgeons towards the pandemic, their life changes, and the strategies they implemented to be able to deal with their patients in such a difficult time., Methods: From April 2021 to May 2021 a modified Delphi method was used to construct, pilot, and refine the questionnaire focused on the evolution of global neurosurgical practice during the pandemic. This survey was distributed among 1000 neurosurgeons; the responses were then collected and critically analyzed., Results: Outpatient department practices changed with a rapid rise in teleservices. 63.9% of respondents reported that they have changed their OT practices to emergency cases with occasional elective cases. 40.0% of respondents and 47.9% of their family members reported to have suffered from COVID-19. 56.2% of the respondents reported having felt depressed in the last 1 year. 40.9% of respondents reported having faced financial difficulties. 80.6% of the respondents found online webinars to be a good source of learning. 47.8% of respondents tried to improve their neurosurgical knowledge while 31.6% spent the extra time in research activities., Conclusions: Progressive increase in operative waiting lists, preferential use of telemedicine, reduction in tendency to complete stoppage of physical clinic services and drop in the use of PPE kits were evident. Respondents' age had an impact on how the clinical services and operative practices have evolved. Financial concerns overshadow mental health.
