An Updated Review Summarizing the Anticancer Potential of Naringenin.

One important phytochemical is naringenin, which belongs to the flavanone class of polyphenols. It is found in citrus fruits, such as grapefruits, but it can also be found in tomatoes, cherries, and other food-grade medicinal plants. Naringenin has a significant chemotherapeutic promise, as several investigations have conclusively shown. Therefore, the goal of this review is to synthesize the literature that has been done on naringenin as a possible anti-cancer agent and clarify the mechanisms of action that have been described in treatment plans for different kinds of cancer. In a variety of cancer cells, naringenin works by affecting several pathways associated with cell cycle arrest, anti-metastasis, apoptosis, anti-angiogenesis, and DNA repair. It has been shown to alter several molecular targets linked to the development of cancer, such as drug transporters, transcription factors, reactive nitrogen species, reactive oxygen species, cellular kinases, and inflammatory cytokines and regulators of the cell cycle. In summary, this research provides significant insights into the potential of naringenin as a strong and prospective candidate for use in medicines, nutraceuticals, functional foods, and dietary supplements to improve the management of carcinoma.

Point-of-care ultrasound (POCUS) in the surgery of a paraplegic pregnant female: A case of "do no harm".

We present here a case of multidisciplinary management of a 20-year-old pregnant woman who presented with sudden paraplegia attributed to a large paraspinal tumor. Magnetic resonance imaging (MRI) revealed compressive dorsal myelopathy due to an extramedullary tumor. Given the urgency of her symptoms and pregnancy status, a multidisciplinary team decided to proceed with surgery while avoiding radiation exposure (eg, O/C-arm). Intraoperative point-of-care ultrasound (POCUS) was utilized for tumor localization and surgical guidance, facilitating successful gross total excision with minimal risk to the fetus. Postoperative recovery was uneventful, with improvement in muscle strength and preservation of the pregnancy. Beyond tumor localization, POCUS offers additional benefits in assessing maternal hemodynamics and detecting potential complications. This case highlights the utility of POCUS as a radiation-free theranostic imaging modality in pregnant patients with spinal tumors, enhancing safety in surgery and optimizing outcomes for both mother and fetus.

From Multiple Protein Docking to Protein-Protein Docking at Interactome Level.

Molecular docking is used to anticipate the optimal orientation of a particular molecule to a target to form a stable complex. It makes predictions about the 3D structure of any complex based on the binding characteristics of the ligand and the target receptor usually a protein. It is an exceptionally useful tool, which is used as a model to study how ligands attach to proteins. Docking can also be used for studying the interaction of ligands and proteins to analyze inhibitory efficacy. The ligand may also be a protein, making it possible to study interactions between two different proteins using the numerous docking tools available for basic research on protein interactions. The protein-protein docking is a crucial approach to understanding the protein interactions and predicting the structure of protein complexes that have not yet been experimentally determined. Moreover, the protein-protein interactions can predict the function of target proteins and the drug-like properties of molecules. Therefore, protein docking assists in uncovering insights into protein interactions and also aids in a better understanding of molecular pathways/mechanisms. This chapter comprehends the various tools for protein-protein docking (pairwise and multiple), including their methodologies and analysis of output as results.

A systematic review of diet and medication use among centenarians and near-centenarians worldwide.

Centenarians represent a phenomenon of successful aging. This systematic review aimed to understand lifestyles and health practices, focusing on diet and medication use for healthy longevity in community-based adults 95 years or over. Medline, CINAHL, Scopus, and gray literature were searched from 1 January 2000 to 10 December 2022. Study quality was assessed using the Modified Newcastle-Ottawa Scale (mNOS). Pooled prevalence [%; 95% confidence interval] for categorical variables and pooled mean for continuous variables were estimated for demographics, weight status, lifestyle factors, medications, and health conditions. Of 3392 records screened, 34 studies were included in the review, and 71% (24/34) met the 6/8 criteria in mNOS. Centenarians/near-centenarians' ages ranged from 95 to 118 years, with 75% (71-78%) female and 78% (68-88%) living in rural areas. They had an overall healthy lifestyle: current smoking (7%; 5-9%), drinking (23%; 17-30%), normal weight (52%; 42-61%), overweight (14%; 8-20%), physical activity (23%; 20-26%), and sleep satisfaction (68%; 65-72%). Diet averaged 59.6% carbohydrate, 18.5% protein, and 29.3% fat; over 60% consumed a diverse diet, and < 20% preferred salty food, contributing to lower mortality risks and functional decline. About half used antihypertensives (49%; 14-84%) or other cardiovascular drugs (48%; 24-71%), with an average of 4.6 medications. Common health issues included impaired basic activities of daily living (54%; 33-74%), hypertension (43%; 21-65%), and dementia (41%; 23-59%). The findings of this systemic review underscore the pivotal role of dietary practice and weight management in healthcare strategies to promote healthy ageing. It also recognises rural living styles and sleep hygiene as potential factors contributing to healthy longevity.

Association of smartphones use, ocular symptoms and binocular dysfunctions in adolescents: a hospital-based cross-sectional study.

PURPOSE: Given the current scenario of increased smartphone use in youth, this study aims to evaluate the proportion of ocular symptoms and binocular dysfunction and their association with smartphone use in adolescents through a hospital-based cross-sectional study. METHODS: The participants were asked to fill out questionnaires related to smartphone use and symptoms of eyestrain experienced (Balik et al. and Kucer). They were asked about the following seven symptoms: blurring of vision, redness, visual disturbance, secretion, inflammation, lacrimation, and dryness. Each symptom out of the 7, was scored on a scale of 0-1 and was used to calculate an Ocular Symptom Score (OSS) by summing the scores of each symptom.Depending upon the duration of smartphone usage, the participants were classified into four groups: <2 hours/day, 2-4 hours/day, 4-6 hours/day, and >6 hours/day. Binocular functions were assessed using near point of convergence (NPC), near point of accommodation (NPA), Accommodative convergence/Accommodation (AC/A) ratio, dissociated heterophoria, and binocular accommodative facility (BAF). RESULTS: A total of 123 smartphone user adolescents, aged 10-19 years were included in this study. The mean age of the study population was 16.58 + 2.8 years, out of which 52.03% were males. Prevalence of ocular symptoms was higher in groups with greater duration of smartphone use (2 to 4, 4 to 6, and >6 hours/day as compared to <2 hours/day: 90.48%, 94.74%, 100% vs. 75% respectively). The mean of NPC was 8.51, it was highest in subjects using smartphones for >6 hours. (p-value = .001). The mean AC/A ratio was 2.83 + 1.03: 1. A low AC/A ratio was associated with a longer duration of smartphone usage (p-value = .0001). The mean of BAF was 7.4 + 3.18 cycles/min, only 30 (24.4%) participants had BAF beyond the normal range (<5 cycles/min). The mean of BAF was lowest in the group with >6 hours/day of smartphone use (p-value < .0001). No significant change was found in NPA and dissociated heterophoria with the duration of smartphone usage. CONCLUSION: Higher duration of smartphone use (>2 hours/day) is associated with various ocular symptoms and binocular dysfunction. However, additional research is necessary to authenticate the results of the study.

Prominent Perspective on Existing Biological Hallmarks of Alzheimer's Disease.

Biomarkers are the most significant diagnosis tools tending towards unique approaches and solutions for the prevention and cure of Alzheimer's Disease (AD). The current report provides a clear perception of the concept of various biomarkers and their prominent features through analysis to provide a possible solution for the inhibition of events in AD. Scientists around the world truly believe that crucial hallmarks can serve as critical tools in the early diagnosis, cure, and prevention, as well as the future of medicine. The awareness and understanding of such biomarkers would provide solutions to the puzzled mechanism of this neuronal disorder. Some of the argued biomarkers in the present article are still in an experimental phase as they need to undergo specific clinical trials before they can be considered for treatment.

Racemose neurocysticercosis: a case series.

Neurocysticercosis (NCC) is a common parasitic condition of the central nervous system in certain parts of the world. The racemose variety of NCC is distinct from the commonly seen parenchymal form. It frequently infiltrates the basal cisterns and Sylvian fissures. Imaging plays a vital role in the diagnosis; however, as their signal intensity is similar to cerebrospinal fluid and due to the absence of enhancement in most cases, imaging diagnosis is often difficult on the conventional MRI sequences. Here, we present five cases of racemose NCC to emphasize the importance of a heavily T2-weighted sequence (Fast Imaging Employing Steady-state Acquisition) sequence in the diagnosing this entity.

Endovascular embolisation of posterior condylar canal dural arteriovenous fistula.

We describe a rare case of dural arteriovenous fistula (dAVF) of the posterior condylar canal in a man in his 30s who presented with recent onset headache and neck pain and subsequently acute intracranial haemorrhage. Radiological workup showed a medulla bridging vein draining dAVF of the right posterior condylar canal supplied by a meningeal branch of the right occipital artery. A dilated venous sac was seen compressing over cerebellar tonsil on the right side. There was acute haemorrhage in the posterior fossa and fourth ventricle. He was successfully managed with transarterial endovascular embolisation via a supercompliant balloon microcatheter without any complication. The balloon microcatheter effectively prevented reflux of the liquid embolic agent into the parent artery and vasa nervosa of lower cranial nerves.

A holistic approach to performance prediction in collegiate athletics: player, team, and conference perspectives.

Predictive sports data analytics can be revolutionary for sports performance. Existing literature discusses players' or teams' performance, independently or in tandem. Using Machine Learning (ML), this paper aims to holistically evaluate player-, team-, and conference (season)-level performances in Division-1 Women's basketball. The players were monitored and tested through a full competitive year. The performance was quantified at the player level using the reactive strength index modified (RSImod), at the team level by the game score (GS) metric, and finally at the conference level through Player Efficiency Rating (PER). The data includes parameters from training, subjective stress, sleep, and recovery (WHOOP straps), in-game statistics (Polar monitors), and countermovement jumps. We used data balancing techniques and an Extreme Gradient Boosting (XGB) classifier to predict RSI and GS with greater than 90% accuracy and a 0.9 F1 score. The XGB regressor predicted PER with an MSE of 0.026 and an R2 of 0.680. Ensemble of Random Forest, XGB, and correlation finds feature importance at all levels. We used Partial Dependence Plots to understand the impact of each feature on the target variable. Quantifying and predicting performance at all levels will allow coaches to monitor athlete readiness and help improve training.

An Unusual Association of Idiopathic Syndrome of Inappropriate Antidiuretic Hormone Secretion (SIADH) With Interstitial Lung Disease (ILD).

Although the syndrome of inappropriate antidiuretic hormone secretion (SIADH) is commonly associated with many lung conditions and drugs used for treating them, no literature describes a direct association between SIADH and interstitial lung disease. This case report discusses a 79-year-old male patient who presented to the emergency department (ED) with altered mental status following a fall. The patient had clinical symptoms and imaging findings concerning interstitial lung disease (ILD), and laboratory tests from the ER indicated severe hyponatremia and an increased white blood cell count, suggesting an unusual clinical picture. Detailed workup and medication reconciliation revealed no other medical conditions or intake of drugs associated with SIADH; however, the patient's low serum osmolality, high urine osmolality, high urine sodium, and improvement in serum sodium level with the initiation of 0.9% saline, salt tablets, and tolvaptan verify the presence of SIADH. While the association between SIADH and ILD is not well documented in medical literature, a few case reports from different regions have indicated a potential link, either through drug-induced ILD or SIADH resolution coinciding with ILD improvement. Hence, we describe a case of idiopathic SIADH, possibly associated with interstitial lung disease. This case demonstrates the importance of recognizing the coexistence of SIADH and ILD, as severe hyponatremia can lead to potential life-threatening neurological consequences.

Surgical Outcomes of Levator Resection in Moderate and Severe Ptosis With a Good Levator Function: A Retrospective Study.

INTRODUCTION: An abnormally drooping upper eyelid in comparison with the normal position in primary gaze refers to ptosis. Levator resection should be the procedure of choice in patients with moderate to severe ptosis and a good levator function. METHODS: In this retrospective study, we analysed the surgical outcomes after large and maximal levator resection in patients with moderate and severe ptosis with a good levator function and Bell's phenomenon. All patients had a good levator function; therefore, levator resection was the procedure of choice. We performed levator resection of 20 mm and above and the desired post-operative correction was achieved. RESULTS: One patient had microcornea, and hence, he was undercorrected and his post-operative marginal reflex distance 1 (MRD 1) was 3 mm. Two patients who had severe ptosis pre-operatively had a post-operative MRD 1 of 3 mm. Rest of the patients had a post-operative MRD 1 of 4 mm. CONCLUSION: Levator resection of 20 mm or more should be performed in patients with congenital simple ptosis with a good levator function and Bell's phenomenon to achieve a favourable post-operative outcome.

Understanding the roles and regulation of mitochondrial microRNAs (MitomiRs) in neurodegenerative diseases: Current status and advances.

MicroRNAs (miRNA) are a class of small non-coding RNA, roughly 21-22 nucleotides in length, which are master gene regulators. These miRNAs bind to the mRNA's 3' - untranslated region and regulate post-transcriptional gene regulation, thereby influencing various physiological and cellular processes. Another class of miRNAs known as mitochondrial miRNA (MitomiRs) has been found to either originate from the mitochondrial genome or be translocated directly into the mitochondria. Although the role of nuclear DNA encoded miRNA in the progression of various neurological diseases such as Parkinson's disease, Alzheimer's disease, Huntington's disease, etc. is well known, accumulating evidence suggests the possible role of deregulated mitomiRs in the progression of various neurodegenerative diseases with unknown mechanism. We have attempted to outline the current state of mitomiRs role in controlling mitochondrial gene expression and function through this review, paying particular attention to their contribution to neurological processes, their etiology, and their potential therapeutic use.

Direct Percutaneous Thrombolysis (DPT): A novel method of salvaging Thrombosed Native Arteriovenous Fistula.

INTRODUCTION: Thrombosed arteriovenous fistulas (AVFs) are either treated by thrombectomy or pharmaco-mechanical thrombolysis with or without percutaneous balloon angioplasty. In this study, we have described an effective and economical technique of salvaging these fistulae using a 20-22-gauge spinal needle and urokinase and have named it direct percutaneous thrombolysis (DPT). MATERIALS AND METHOD: This prospective study comprised of 148 patients out of which 120 patients presented with AVF thrombosis and were divided into two groups; those with no obvious stenosis on ultrasound (n = 38) and second with venous stenosis (n = 82). Remaining 28 patients developed thrombosis post angioplasty for venous stenosis. Percutaneous injection of urokinase into the thrombus was done under ultrasound guidance, followed by balloon angioplasty if there was associated stenosis. RESULTS: In 38 patients who didn't have any stenosis, 32 AVFs were successfully thrombolysed by DPT, with technical success of 84.2%. Remaining six patients required angioplasty because of chronic nature of clot. In 82 patients who had venous stenosis, 80 cases were treated successfully by DPT followed by angioplasty with technical success of 97.5%. In third group (n = 28), who developed thrombosis post angioplasty, 100% success rate was noted. The mean length of thrombus was 31.4 ± 4.6 mm and mean diameter of thrombosed vein was 10.5 ± 1.2 mm. There were no major complications encountered during the procedure. Minor complications were seen in 19 patients which included prolonged oozing from puncture site and local hematoma formation. CONCLUSION: Ultrasound guided DPT with urokinase is a safe and economical option for salvaging thrombosed AVF without vascular stenosis that does not need angioplasty.

Cyclin-Dependent Kinase 5 Regulates cPLA2 Activity and Neuroinflammation in Parkinson's Disease.

Hyperactivation of cyclin-dependent kinase 5 (Cdk5) by p25, contributes to neuroinflammation causing neurodegeneration in Parkinson's disease (PD) and Alzheimer's disease. However, the mechanism by which Cdk5 induces neuroinflammation in the PD brain is largely unexplored. Here, we show that Cdk5 phosphorylates cytosolic phospholipase A2 (cPLA2) at Thr-268 and Ser-505 sites lead to its activation and generation of eicosanoid products. Mutational studies using site-directed mutagenesis and molecular simulations show that the architecture of the protein changes on each single-point mutation. Interestingly, double mutations also led to a severe decline in the activity of cPLA2 and to the disruption of its translocation to the plasma membrane. Further, the brain lysates of transgenic PD mouse models show hyperactivation of Cdk5, resulting in enhanced phosphorylation of Thr-268 and Ser-505 of cPLA2 and its heightened activity, confirming the findings observed in the cell culture model of PD. These phosphorylation sites of cPLA2 and Cdk5 could be explored as the future therapeutic targets against neuroinflammation in PD. Further, conjoint transcriptomic analysis of the publicly available human PD datasets strengthens the hypothesis that genes of the arachidonic acid, prostaglandin synthesis, and inflammatory pathways are significantly upregulated in the case of PD patients compared with that of healthy control subjects.
