    Abstract Graphene quantum dots (GQDs) are a luminescent class of carbon nanomaterials with a graphene-like core structure, possessing quantum confinement and edge effects. They have gained importance in the biological world due to their inherent biocompatibility, good water dispersibility, excellent fluorescence and photostability. The improved properties of GQDs require the logical enactment of functional groups, which can be easily attained through post-synthetic non-covalent routes of modification. In this regard, the present work has for the first time employed a simple one-pot post-modification method utilizing the salt of amino caproic acid, an FDA approved reagent. The adsorption of the modifier on GQDs with varying weight ratios is characterized through DLS, zeta potential, Raman, absorption and fluorescence spectroscopy. A decrease of 20% in the fluorescence intensity with an increase in the modifier ratio from 1 to 1000 and an increased DLS size as well as zeta potential demonstrate the efficient modification as well as higher stability of the modified GQDs. The modified GQDs with a high weight ratio (1 : 100) of the modifier showed superior ability to sense dopamine, a neurotransmitter, as well as competent biofilm degradation ability. The modified GQDs could sense more efficiently than pristine GQDs, with a sensitivity as low as 0.06 μM (limit of detection) and 90% selectivity in the presence of other neurotransmitters. The linear relationship showed a decrease in the fluorescence intensity with increasing dopamine concentration from 0.0625 μM to 50 μM. Furthermore, the efficiency of the modified GQDs was also assessed in terms of their antibiofilm effect against

    Abstract Sialidosis, a rare autosomal recessive disorder, is caused by a deficiency of NEU1 encoded enzyme alpha-N-acetyl neuraminidase. We report a premature male with neonatal-onset type II sialidosis which was associated with left ventricular dysfunction. The clinical presentation and subsequent progression which culminated in his untimely death at 16 months of age are succinctly described. Early-onset cardiovascular involvement as noted in this patient is not well characterised. The case report is supplemented by a comprehensive review of the determinants, characteristics, and the clinical course of cardiovascular involvement in this rare condition.

    Abstract Chromosome 1p36 deletion syndrome is a common genetic anomaly (prevalence: 1 in 5,000-1 in 10,000). Despite reports of cardiovascular involvement, the cardiovascular phenotypic spectrum of patients with 1p36 deletion syndrome is not well characterized. In this article, we reported the clinical course of a full-term African American boy with chromosome 1p36 deletion syndrome and neonatal onset of severe cardiac disease with moderate-to-severe biventricular dysfunction and severe pulmonary hypertension. Early neonatal onset presentation of 1p36 deletion syndrome is rare and might be associated with a more guarded prognosis. This case based study is supplemented by a comprehensive review of cardiovascular involvement in this relatively common genetic syndrome.

    Abstract A 75-year-old female with no history of lung disease developed severe pulmonary fibrosis within 1 month of acute severe COVID-19 pneumonia. She developed dry basal crackles, hypoxia needing home oxygen, and computed tomography changes which dramatically evolved from acute ground-glass opacities to honeycombing and traction bronchiectasis. Interestingly, these changes occurred despite her being on steroids through most of her hospital stay. She is being commenced on pirfenidone and her responses are carefully monitored, but the role of antifibrotic drugs are unclear and will only be established from large clinical trials.

    Abstract Background and overview: Trigeminal neuralgia due to a metastatic lesion is a relatively rare occurrence. These cases pose a diagnostic challenge for the clinician due to a complex clinical presentation.
    Case description: The authors describe the case of a 65-year-old woman with left-sided facial pain and occasional numbness. The patient also reported autonomic features associated with facial pain, facial muscular weakness, and hearing and visual impairment. The patient's history of breast cancer, for which she was receiving treatment for bone metastasis, warranted diagnostic imaging. Magnetic resonance imaging with and without contrast was performed and revealed a possible metastatic lesion.
    Conclusions and practical implications: Unusual clinical features must be identified, and prompt appropriate imaging is instrumental in making at an accurate diagnosis and management plan.

The linear relationship showed a decrease in the fluorescence intensity with increasing dopamine concentration from 0.0625 μM to 50 μM. Furthermore, the efficiency of the modified GQDs was also assessed in terms of their antibiofilm effect against Staphylococcus aureus. The unmodified GQDs showed only 10% disruption of the adhered bacterial colonies, while the modified GQDs (1 : 100) showed significantly more than 60% disruption of the biofilm, presenting the competency of the modified GQDs. The unique modifications of GQDs have thus proven to be an effective method for the proficient utilization of zero-dimensional carbon nanomaterials for biosensing, bioimaging, antibacterial and anti-biofilm applications.

    Abstract Objective: In otolaryngology, it is important to minimize the use of opioids for post-operative analgesia given the rise in opioid abuse and mortality due to overdose in the United States. We sought to quantitatively determine the efficacy of non-opiate analgesia in postoperative pain management after microdirect laryngoscopy (MDL).
    Methods: This is a single institution prospective study monitoring post-operative pain using a visual analog scale (VAS, 1-10). Patients with a history of vocal fold lesions, paralysis, and stenosis who underwent MDL were surveyed for one month following their procedure (daily for the first week and weekly thereafter). Student's t-test was used to determine whether short (1 week) and long term (1 month) pain was controlled by over-the-counter (OTC) medications. We defined adequate pain control as an average daily VAS score below 4 for the first 4 days and below 1 in the following 3 weeks and hypothesized that patients would report adequate pain control without the use of opioids.
    Results: Post-operative pain after MDL was generally mild. The average daily VAS score was 2.16 (95% CI [0.0-5.2], P = 0.0014) in the first 4 days post-procedure and 0.28 (95% CI [0.0-1.3], P = 0.0007) in the 3 weeks post-procedure confirming our hypothesis. On average, patients used 3.14 (CI: [0.0-12.8]) pills of acetaminophen and 0.57 (CI: [0.0-4.7]) pills of an NSAID per day in the first week. Only three patients required opioid analgesia, all of whom used opioids in the first 48 h.
    Conclusions: OTC analgesics provide sufficient pain control after microdirect laryngoscopy for most patients. Given the potential for substance abuse from opioid medications, this study demonstrates that adequate pain control requires, at most, 48 h of opioid medications. Further study is needed to determine factors that contribute to increased pain after laryngoscopy.

    Abstract Now a day’s advancement in technology increases the use of automation, mobility, smart devices, and application over the Internet that can create serious problems for protection and the privacy of digital data and raised the global security issues. Therefore, the necessity of intelligent systems or techniques can prevent and protect the data over the network. Cyberattack is the most prominent problem of cybersecurity and now a challenging area of research for scientists and researchers. These attacks may destroy data, system, and resources and sometimes may damage the whole network. Previously numerous traditional techniques were used for the detection and mitigation of cyberattack, but the techniques are not efficient for new attacks. Today’s machine learning and metaheuristic techniques are popularly applied in different areas to achieve efficient computation and fast processing of complex data of the network. This paper is discussing the improvements and enhancement of security models, frameworks for the detection of cyberattacks, and prevention by using different machine learning and optimization techniques in the domain of cybersecurity. This paper is focused on the literature of different metaheuristic algorithms for optimal feature selection and machine learning techniques for the classification of attacks, and some of the prominent algorithms such as GA, evolutionary, PSO, machine learning, and others are discussed in detail. This study provides descriptions and tutorials that can be referred from various literature citations, references, or latest research papers. The techniques discussed are efficiently applied with high performance for detection, mitigation, and identification of cyberattacks and provide a security mechanism over the network. Hence, this survey presents the description of various existing intelligent techniques, attack datasets, different observations, and comparative studies in detail.

    Abstract Heavy metals' amassment in the soil environment is a threat to crop and agricultural sustainability and consequentially the global food security. For achieving enhancement of crop productivity in parallel to reducing chromium (Cr) load onto food chain demands continuous investigation and efforts to develop cost-effective strategies for maximizing crop yield and quality. In this context, we investigated the amelioration of Cr(VI) toxicity through β-pinene in experimental dome simulating natural field conditions. The protective role of β-pinene was determined on physiology, morphology and ultrastructure in Zea mays under Cr(VI) stress (250 and 500 μM). Results exhibited a marked reduction in the overall growth (shoot and root length and dry matter) of Z. mays plants subjected to Cr(VI) stress. Photosynthetic pigments (chlorophyll and carotenoids) were evidently reduced, and there was a loss of membrane integrity. Supplementation of β-pinene (100 μM), however, declined the toxicity induced by Cr(VI). Interestingly, Cr-tolerant abilities were improved in relation to plant growth, photosynthetic pigments and membrane integrity with the combined treatment of Cr(VI) and β-pinene. β-Pinene also reduced the root-mediated uptake of Cr(VI) and translocation to shoots. Moreover, significant ultrastructural damages recorded in roots and shoots under Cr(VI) stress were partially reverted upon addition of β-pinene. Our analyses revealed that β-pinene mitigates Cr(VI) toxicity in Z. mays, either by membrane stabilization or serving as a barrier to the uptake of Cr from soil. Thus, exogenous supply of β-pinene can be an effective alternative to mitigate Cr toxicity in soil. However, it is deemed essential to investigate further the responses throughout the life cycle of the plant on β-pinene supplementation under natural conditions.
