Abstract
Large-vessel occlusion (LVO) stroke is a promising field for the use of AI, especially machine learning (ML) because optimal results are highly dependent on timely diagnosis, communication, and treatment. In order to better understand the current state of artificial intelligence (AI) in relation to LVO strokes, its efficacy, and potential future applications, we searched relevant literature to perform a comprehensive evaluation of the topic. The databases PubMed, Embase, and Scopus were extensively searched for this review. Studies were then screened using title and abstract criteria and duplicate studies were excluded. By using pre-established inclusion and exclusion criteria, it was decided whether or not to include full-text papers in the final analysis. The studies were analyzed, and the relevant information was retrieved. In recognizing LVO on computed tomography, ML approaches were very accurate. There is a shortage of AI applications for thrombectomy patient selection, despite the fact that certain research accurately evaluates individual patient eligibility for endovascular therapy. Machine learning algorithms may reasonably predict clinical and angiographic outcomes as well as associated factors. AI has shown promise in the diagnosis and treatment of people who have just suffered a stroke. However, the usefulness of AI in management and forecasting remains restricted, necessitating more studies into machine learning applications that can guide decision making in the future.

Abstract
In this report, ZnO nanoparticles were biosynthesized using Paspalum scrobiculatum grains extract for the first time. GC-MS analysis explicated that diethyl phthalate was the major phytocompound with 94.09% in aqueous extract. ZnO nanoparticles formation was confirmed by various physicochemical analyses. HR-TEM images showed the hexagonal, rectangular shaped nanoparticles in 15-30 nm size. The antioxidant, anti-inflammatory, and anti-diabetic analyses showed the effective bioactivity of ZnO nanoparticles in 80 μg/ml concentration with 95.36%, 94.08%, and 91.96%, respectively. The morphological and tissue changes witnessed in larvicidal and insecticidal activities against Culex tritaeniorhynchus and Tribolium castaneum revealed the efficient nature of ZnO nanoparticles in 100 ppm at 48 h and 100 μg/kg at 72 h, respectively. The morphological changes in antibacterial activity demonstrated the bactericidal nature of ZnO nanoparticles against Salmonella typhi and Staphylococcus aureus in 150 μg/ml concentration. The morphological observations in anticancer activity against HepG2 liver cancer cells showed the potent drug features of ZnO nanoparticles in 100 μg/ml concentration with 97.18% of cytotoxicity. The ZnO nanoparticles showed no toxicity against HDF normal cells in lower concentrations and it explicated the biocompatible features of nanoparticles. The Vigna radiata plant growth was efficiently promoted by low (60 ppm) concentration of nanoparticles. The ZnO nanoparticles divulged effective degradation of IPA, EDTA, BQ, and DPBF in 75%, 45%, 55%, and 80% through ROS formation, respectively. Thus, the synthesized ZnO nanoparticles are biocompatible and inexpensive material compared to the traditional one and can be utilized as an efficient material in biological fields.

Abstract
Electrical shock can result in neurological complications, involving both peripheral and central nervous systems, which may present immediately or later on. High-voltage electrical injuries are uncommonly reported and may predispose to both immediate and delayed neurologic complications. We report the case of a 68-year-old man who experienced a high-voltage electrocution injury, subsequently developed bulbar dysfunction and spontaneously recovered. We describe the development of bulbar palsy following a significant electrical injury, which showed no evidence of this on magnetic resonance imaging. High-voltage electrocution injuries are a serious problem with potential for both immediate and delayed neurologic sequelae. The existing literature has no reports on bulbar dysfunction following electrocution, apart from motor neuron disease.

Abstract
BACKGROUND Chronic pancreatitis (CP) found in the tropical countries is known to have a higher risk for carcinoma of the pancreas. This study aimed to explore the clinical profile of pancreatic intraepithelial neoplasia (PanIN), one of the precursors of carcinoma of the pancreas, in tropical CP and to identify the possible clinical predictors of the same. METHODOLOGY A retrospective study was done enrolling patients who underwent either Frey's procedure or pancreatic resection for symptomatic CP, between January 2008 and December 2012. They were grouped into PanIN positive and PanIN negative based on histopathology. Their clinical and laboratory parameters were compared statistically to identify the predictors of the PanIN status. RESULTS Sixty-two tropical CP patients who had Frey's procedure or pancreatic resection were enrolled into this study; 38.7 % cases showed PanIN changes and 61.29 % had no PanIN changes. Majority of the clinical and laboratory parameters were found comparable between the two groups except obstructive jaundice and CA 19-9 value >137.5 which were there in 54.2 % of PanIN-positive cases. On histopathology, 54.83 % cases were benign CP and 45.16 % were malignant CP. Among the benign CP, 33.3 % were PanIN positive and among those with malignancy 66.7 % were PanIN positive. Low-grade PanINs were seen in 73 % cases of benign CP and in 26.1 % of malignancy whereas high-grade PanIN-3 lesions were seen exclusively in patients with malignancy. CONCLUSION High-grade PanIN-3 lesions showed significant association with pancreatic malignancy. Obstructive jaundice and CA 19-9 ≥ 137.5 could predict PanIN positivity.
