The Neuroprotective Effects of Agmatine on Parkinson's Disease: Focus on Oxidative Stress, Inflammation and Molecular Mechanisms.

Agmatine (AGM), a naturally occurring polyamine derived from L-arginine, has shown significant potential for neuroprotection in Parkinson's Disease (PD) due to its multifaceted biological activities, including antioxidant, anti-inflammatory, and anti-apoptotic effects. This review explores the therapeutic potential of AGM in treating PD, focusing on its neuroprotective mechanisms and evidence from preclinical studies. AGM has been demonstrated to mitigate the neurotoxic effects of rotenone (ROT) by improving motor function, reducing oxidative stress markers, and decreasing levels of pro-inflammatory cytokines in animal models. Additionally, AGM protects against the loss of TH + neurons, crucial for dopamine synthesis. The neuroprotective properties of AGM are attributed to its ability to modulate several key pathways implicated in PD pathogenesis, such as inhibition of NMDA receptors, activation of Nrf2, and suppression of the HMGB1/ RAGE/ TLR4/ MyD88/ NF-κB signaling cascade. Furthermore, the potential of agmatine to promote neurorestoration is highlighted by its role in enhancing neuroplasticity elements such as CREB, BDNF, and ERK1/2. This review highlights agmatine's promising therapeutic potential in PD management, suggesting that it could offer both symptomatic relief and neuroprotective benefits, thereby modifying the disease course and improving the quality of life for patients. Further research is warranted to translate these preclinical findings into clinical applications.

Prevalence of Second Hand Smoke Exposure and Measures to Overcome: A Cross Sectional Study among Youth in Urban Hyderabad.

ABSTRACT: In India, the prevalence of secondhand smoke (SHS) exposure is 29.5% in general and 11.2% at home. The youth may expose themselves to SHS without knowing the risk factors and consequences involved. This study is intended to determine the prevalence of SHS exposure and the measures adopted by the youth to avoid exposure. A cross-sectional study was conducted among 338 youth in an urban area in Hyderabad. A modified Global Youth Tobacco Survey questionnaire was used for data collection on SHS exposure and avoidance. The total prevalence of SHS exposure was 35.21%. The mean days of SHS exposure/week were 1.419 (standard deviation -1.806) days. Belonging to the age group 18-21 years, and male gender were significant predictors of SHS exposure. Education of the head of family was a significant predictor of SHS avoidance behavior. Creating awareness among young adults regarding the deleterious effects and preventive strategies of SHS exposure, thereby making them responsible for the health of their family can be a protective long-term strategy.

Additive-manufactured paper-PMMA hybrid microfluidic chip for simultaneous monitoring of creatinine and pH in artificial urine.

Nowadays, kidney dysfunction is a common health issue due to the modernized lifestyle. Even though medications are commercially available to treat kidney diseases, early diagnosis is crucial and challenging. Clinically, measuring urine creatinine and pH has gained significant interest as a way to diagnose kidney diseases early. In the present work, we attempted to develop a low-cost, robust, accurate and naked-eye colorimetric method to determine both creatinine levels and pH variations in artificial urine samples using a simple 3D-printed hybrid microfluidic device. Creatinine was detected by the incorporation of the traditional Jaffe test onto the hybrid paper-PMMA microfluidic device and pH (4-8) was measured by a simple anthocyanin test. Notably, the tests were established without employing any sophisticated or costly instrument clusters. The developed 3D-printed microfluidic probe showed a limit of detection (LOD) of 0.04 mM for creatinine over a concentration range of 1-10 mM, with a regression coefficient (R2) of 0.995 in laboratory conditions. Interestingly, the experimental data obtained with artificial urine exhibited a wide linear range from 0.1 mM to 5 mM under different pH values ranging from 4 to 8 in the presence of matrices commonly found in urine samples other than proteins, indicating the potential use of this method in pre-clinical analysis. Since the wide linear range of urine creatinine in artificial urine samples falls well below the clinically relevant concentrations in humans (0.07-0.27 mM), the developed lab-on-chip device is further suitable for clinical evaluation with proper ethical clearance. This 3D-printed hybrid microfluidic colorimetry-based creatinine detection and pH indicator platform can be beneficial in the healthcare sector due to the on-site testing capability, cost-effectiveness, ease of use, robustness, and instrument-free approach.

Effectiveness of Pranic Healing as complementary therapy on lower urinary tract symptoms and sleep: Single-blind randomized trial.

BACKGROUND: Benign Prostatic Hyperplasia (BPH) commonly affects older men, leading to lower urinary tract symptoms (LUTS) that affect sleep and quality of life. This study evaluates the effect of Pranic Healing (PH) as a complementary therapy for bothersome LUTS by normalising biofield energy centres called Chakras. METHODOLOGY: A single blind trial involving 76 men with LUTS was conducted, randomised into Medication-only (MED) and Medication-plus-Pranic Healing (MEDPH) groups. The MEDPH received PH sessions twice weekly for 5 weeks. RESULTS: The study compared MED (n = 30) and MEDPH (n = 36) participants, finding significant improvements in IPSS scores (p ≤ .001) in both groups. The MEDPH group showed a greater reduction in incomplete bladder emptying and intermittency. The post void residual volume increased significantly in the MED group (Wilcoxon Z = -2.335, p = .02), while the MEDPH group reduced non-significantly. Sleep quality index improved significantly (McNemar=.013) in the MEDPH group, while the MED group showed no significant change. Subjective sleep quality, duration, and latency improved significantly in the MEDPH group. Healers reported improved energy balance in chakras of MEDPH group. Perceived energy by healers in lower chakra relates to urinary parameters. CONCLUSION: PH could alleviate LUTS, enhancing quality of life due to urination, and improved sleep, among moderate BPH patients. TRIAL REGISTRATION: This study has been registered under the Clinical Trial Registry of India. (CTRI No: CTRI/2023/01/049004).

Energy-efficient quad tree-based clustering using edge-assisted UAV-relay to enhance network lifetime in WSN.

Wireless sensor networks' most prominent concern is energy optimization. It faces significant problems like high energy consumption, data loss, delay, and low network lifetime. To improve, it uses clustering. However, during clustering, coverage holes are most likely to appear near the network's edge, within the cluster, and between clusters. As a result, there are more energy holes and dead nodes; therefore, the goal of this work is to maximize node network lifetime and minimize energy consumption during data transmission in the wireless sensor network (WSN). The proposed work includes three entities: sensor nodes, an edge-assisted unmanned aerial vehicle (UAV), and a base station. It uses an edge-assisted unmanned aerial vehicle to provide additional resources to the UAV, which helps reduce energy consumption during data transmission. This research proposes using communication to enhance the speed and bandwidth of data transmission and reduce transmission latency. This work attempts to improve performance by increasing throughput.

Polytyrosine-Coated Paper Electrode for Sensitive and Selective Sensing of NADH.

Reduced nicotinamide adenine dinucleotide (NADH)-detecting electrochemical sensors are attractive in monitoring and diagnosing various physiological disorders of NADH abnormalities. The NADH detection methods using conventional electrodes are challenging due to slow electron transfer and fouling effect. Interestingly, paper-based flexible and disposable electrodes (PE) are superior for sensing biomolecules through simple detection procedures with excellent sensitivity and selectivity. Herein, to construct a conducting polypeptide-modified paper electrode, initially, polytyrosine (PTyr) is synthesized from l-tyrosine N-carboxy anhydride through ring-opening polymerization, and PTyr is drop-coated on the PE. The PTyr-modified paper electrode (PMPE) demonstrated excellent electrochemical properties and facilitated the electrooxidation of NADH at a lower potential of 576 mV. The PMPE displayed a linear detection between 25 and 145 µM of NADH concentration, with a lower detection limit of 0.340 µM. Under ideal circumstances, the sensor developed displayed an excellent NADH detection capability without interference with the most common electroactive species, ascorbic acid. The PMPE facilitates good electrocatalytic activity toward NADH, which can also be employed as a substrate material for biofuel cells.

Multi-gigabit X-band transmitter for satellite communication using the optical phase-locked loop.

Optical generation of microwave signals using photonic techniques offers benefits of frequency agility, ease of frequency scaling, and reduced hardware complexity. We demonstrate the generation and detection of QPSK modulated with symbol rates up to 5 GBaud at carrier frequencies of 8-12 GHz through optical heterodyning of two-phase-locked lasers. The received data is demodulated through appropriate post-processing to correct for the phase noise and IQ imbalance. The approach is scalable to mmWave and THz communication.

Gastric sleeve as an extra-anatomical roux for biliary reconstruction in a pediatric third liver transplant.

BACKGROUND: Sir Roy Calne in 1976 described "Biliary reconstruction is the Achilles heel of liver transplantation," and it remains true. In some patients, such as those with short-gut syndrome and concomitant biliary atresia, neither duct to duct nor Roux biliary reconstruction is feasible. METHODS: We present a case of child's third liver transplant (LT), where an innovative extra-anatomical biliary bypass was created using a sleeve from greater curvature of the stomach. RESULTS: The patient is well nearly 10 years following the LT. CONCLUSIONS: This technique could prove to be an important addition to the armamentarium of a surgeon in difficult retransplants and in patients with short-gut syndrome as it provides a viable option with good long-term outcome.

Exploring the complexities of megacystis-microcolon-intestinal hypoperistalsis syndrome: insights from genetic studies.

Megacystis microcolon intestinal hypoperistalsis syndrome (MMIHS) is an uncommon genetic disorder inherited in an autosomal recessive pattern that affects the muscles that line the bladder and intestines. The most common genes associated with MMIHS mutations are ACTG2, LMOD1, MYH11, MYL9, MYLK, and PDCL3. However, the complete genetic landscape of MMIHS still needs to be fully understood. The diagnosis of MMIHS can be challenging. However, advances in prenatal and diagnostic techniques, such as ultrasound and fetal urine analysis, have improved the ability to detect the syndrome early. Targeted next-generation sequencing (NGS) and other diagnostic tests can also diagnose MMIHS. The management of MMIHS involves addressing severe intestinal dysmotility, which often necessitates total parenteral nutrition (TPN), which can lead to complications such as hepatotoxicity and nutritional deficiencies. Multivisceral and intestinal transplantation has emerged as therapeutic options, offering the potential for improved outcomes and enteral autonomy. Understanding the genetic underpinnings of MMIHS is crucial for personalized care. While the prognosis varies, timely interventions and careful monitoring enhance patient outcomes. Genetic studies have given us valuable insights into the molecular mechanisms of MMIHS. These studies have identified mutations in genes involved in the development and function of smooth muscle cells. They have also shown that MMIHS is associated with defects in the signaling pathways that control muscle contraction. Continued research in the genetics of MMIHS holds promise for unraveling the complexities of MMIHS and improving the lives of affected individuals.

Advances in Lingual Thyroid Management Using Coblation Technology: A Case Series Study.

Lingual thyroid is a rare, abnormal ectopic thyroid tissue seen at the base of the tongue. It is a rare embryological anomaly caused by the failure of the descendence of the thyroid gland from the foramen caecum to its normal prelaryngeal area. The main aim of our study is to discuss recent advancements in the management of lingual thyroid using coblation technology. We are discussing the prospective study of 12 lingual thyroid cases that came to the government ENT hospital, Koti, in Hyderabad, from July 2016 to July 2023. All patients were assessed by a detailed history, blood investigations, fine needle aspiration cytology, radiological investigations, technetium-99 scintigraphy, and an endocrinologist opinion. In our study, all cases were hypothyroid and showed difficulty in swallowing and a few cases showed bleeding from the mouth, and difficulty in breathing, hence all 12 cases underwent coblation-assisted excision of swelling and with lifelong thyroxine supplementation. For all 12 cases, demographic, clinicopathological data and radiological data were recorded. Treatment depends on the age of the patient, the severity of symptoms, precipitating factors like puberty or pregnancy, or any other comorbidities with the disease. In our study, all cases were symptomatic and hypothyroid status, hence all 12 cases underwent coblation-assisted excision of swelling and lifelong thyroxine supplementation. All cases were followed up for 2 years with good recovery, minimal patient discomfort after surgery, and lifelong levothyroxine supplementation. Lingual thyroids have a female preponderance. In our study, all were female. Thyroid scintigraphy plays an important role in diagnosis, along with ultrasonography. In all symptomatic cases, surgery with Coblation-assisted excision of swelling is the treatment of choice, with good recovery, minimal patient discomfort after surgery and with lifelong levothyroxine supplementation.

Invasive Sinusitis Presenting with Orbital Complications in COVID Patients: Is Mucor the Only Cause?

The second wave of COVID pandemic was associated with an outbreak of Mucormycosis. The mortality rate of Mucormycosis reaches 50-80% in cases with orbital and intracranial extension (Fadda in Acta Otorhinolaryngol Ital 41:43-50, 2021). In this outbreak we found that few of these patients had bacterial invasive sinusitis mimicking fungal sinusitis. Amphotericin the only effective drug against Mucormycosis is highly toxic and expensive and not indicated in bacterial sinusitis. Our aim was to  determine the exact etiologic agent, predisposing factors and outcome of treatment of COVID associated invasive sinusitis presenting with orbital complications. It is a retrospective observational study done in 33 patients with orbital complications in COVID associated invasive sinusitis. Demographic details of the patients and clinical presentation were documented. Rhinological examination was done and a nasal swab was taken for KOH mount along with Gram`s stain and Culture and Sensitivity. All Patients underwent radiological evaluation by contrast enhanced computed tomography (CECT) or MRI. Liposomal Amphotericin B was started. Surgical debridement done. Amphotericin-B was stopped in cases reported negative for fungal elements and antibiotics administered for two weeks. Outcome of treatment was documented. A total of 33 patients were included in the study. 48.5% patients were found to have bacterial infection and 27.3% patient's fungal infections and 24.2% mixed infections.Eschar formation, necrotic tissue, erosion of the lamina papyracea was seen in both Klebsiella (33.3%) and Staphylococcal infections (16.6%) similar to Mucor and mixed infections. Persistent opthalmoplegia and deterioration of vision was associated with Mucor and mixed infections. However improvement in proptosis, ptosis, ophthalmoplegia, and vision was observed in cases associated with bacterial invasive sinusitis. Invasive bacterial sinusitis was under diagnosed during second wave of COVID. Identification of invasive bacterial sinusitis can help in de-escalation of treatment.

Effect of Drill Induced Noise on Contralateral Normal Ear Following Cortical Mastoidectomy.

INTRODUCTION: Chronic suppurative otitis media (CSOM) is a long standing infection of the middle ear cleft. Mastoidectomy, with or without tympanoplasty, is the preferred treatment for CSOM. However, the drill used during ear surgery generates noise that may potentially cause hearing damage in both the operated and opposite inner ear, leading to temporary or permanent hearing loss. MATERIALS AND METHODS: The study included patients diagnosed with CSOM who underwent surgeries in the Otorhinolaryngology department. Postoperatively, all patients were followed up on the 7th day and 1 month after the surgery. Pure Tone Audiometry (PTA) was performed to evaluate the hearing outcomes. RESULTS: A total of 61 patients were included in the study. The mean preoperative PTA of contralateral ear bone conduction among the study participants was 6.48. At the 7th day post-operation, the mean post-operative PTA of contralateral ear bone conduction for the same participants was 7.77. This difference was statistically significant according to the Paired T-test (P = 0.001).However, when evaluating the mean preoperative PTA of contralateral ear bone conduction (6.48) and the mean post-operative PTA at 1st month (6.02), the difference was not statistically significant (P = 0.208).Additionally, there was no statistical difference in air conduction and air-bone gap before and after surgery. CONCLUSION: The study suggests that mastoid drilling is associated with a significant temporary hearing loss in the contralateral ear immediately after surgery, which eventually recovers within a month. However, the hearing loss is considered negligible and not statistically significant in the long term. It is worth considering additional audiological investigations, such as otoacoustic emissions, to detect this type of hearing loss more accurately.

Disposable paper electrodes for detection of changes in dopamine concentrations in rat brain homogenates.

Dopamine, the main catecholamine neurotransmitter plays an important role in renal, cardiovascular, central nervous systems, and pathophysiological processes. The abnormal dopamine levels can result in neurological disorders such as Parkinson's, Alzheimer's, schizophrenia, acute anxiety, neuroblastoma and also contribute to cognitive dysfunctions. Given the widespread importance of dopamine concentration levels, it is imperative to develop sensors that are able to monitor dopamine. Herein, we have developed pre-anodized disposable paper electrode modified with 1-pyrenebutyric acid, for the selective and sensitive determination of dopamine. The sensor was characterized with Fourier transform infrared spectroscopy, Energy dispersive X-ray spectroscopy, X-ray photoelectron spectroscopy, and electrochemical techniques for addressing the robust formation and electrochemical activity. The modified electrode exhibited excellent electrocatalytic activity towards dopamine without the common interference from ascorbic acid. The calibration plot for the dopamine sensor resulted linear range from 0.003 µM to 0.5 µM with a detection limit of 0.11 nM. The sensor's potential utility was tested by monitoring dopamine concentration changes in rat brain homogenates when subjected to neurotoxicity. The developed sensor was validated with gold-standard UV-Vis spectroscopy studies and computational studies were performed to understand the interaction between 1-pyrenebutyric acid and dopamine.

Combination of self-assembling system and N,O-carboxymethyl chitosan improves ocular residence of anti-glaucoma drug.

Glaucoma is known to be one of the principal causes of vision loss due to elevated intraocular pressure. Currently, latanoprost eye drops is used as first-line treatment for glaucoma; however, it possesses low bioavailability due to rapid precorneal clearance. A novel delivery system with a mucoadhesive property could overcome this problem. Therefore, we attempt to develop a combination of self-assembling latanoprost nanomicelles (Latcel) and a mucoadhesive polymer (N,O-carboxymethyl chitosan: N,O-CMC) to improve the corneal residence time. Latcel was developed using Poloxamer-407 by thin film hydration method, followed by the addition of N,O-CMC using simple solvation to obtain Latcel-CMC and characterized using various physicochemical characterization techniques. The particle size of Latcel-CMC was 94.07 ± 2.48 nm and a zeta potential of -16.03 ± 0.66 mV, with a sustained release for 24h whereas marketed latanoprost drops released 90 % of the drug within 1h. In vitro cytotoxicity studies, HET-CAM, and in vivo Draize test showed the biocompatibility of Latcel-CMC. Cellular uptake studies performed using fluorescein isothiocyanate (FITC) loaded nanomicelles in human corneal epithelial cells indicates the increased cellular uptake as compare to plain FITC solution. In vivo ocular residence time was evaluated in Wistar rats using Indocyanine green (ICG) loaded nanomicelles by an in vivo imaging system (IVIS), indicating Latcel-CMC (8h) has better residence time than plain ICG solution (2h). The Latcel-CMC showed improved corneal residence time and sustained release of latanoprost due to increased mucoadhesion. Thus, the developed N,O-Carboxymethyl chitosan based nanomicelles eye drop could be a better strategy than conventional eye drops for topical delivery of latanoprost to treat glaucoma.

A promising 'single' and 'dual' drug-nanocomposite enriched contact lens for the management of glaucoma in response to the tear fluid enzyme.

Glaucoma is a neurodegenerative condition that results in the damage of retinal ganglion cells due to elevated intraocular pressure (IOP). To curtail the limitations associated with conventional treatments such as eye drops and ocular suspensions, we have developed 'single' and 'dual' drug delivery contact lenses (CLs), that is, latanoprost (LP) and latanoprost-timolol (LP-TM) deliverable CLs, in response to lysozyme (Lyz), which is abundant in the lacrimal fluid. Since chitosan (CS) can entrap more of the drug and also undergo hydrolysis in the presence of Lyz, we have employed CS for the composite preparation. The CL fabrication was performed by free radical copolymerization of poly(2-hydroxyethyl methacrylate) (pHEMA) in the presence of the drug-loaded nanocomposite with UV-curing initiators using the pre-drug loading strategy. The surface morphological, optical and mechanical investigations confirmed the presence of the drugs, ≥80% transparency, the adequate flexibility and biocompatibility of both the CLs. The in vitro release experiments showed the release of 95.86% LP from LP-CL, and 83.87% LP and 86.70% TM from LP-TM-CL in the presence of 1.5 mg mL-1 of Lyz in 72 h. In vitro biocompatibility assay against human corneal epithelial (HCE) cells and ex vivo experiments on HET-CAM confirmed that the fabricated LP-CL and LP-TM-CL are well tolerated. Moreover, in vivo safety evaluations of CLs on New Zealand white rabbit eyes suggest no sign of irritation to the ocular tissues within 72 h of observation. Hence, the study suggests that the 'single' and 'dual' drug-loaded CLs could open a new avenue to manage glaucoma by maintaining mean diurnal IOP.

Eco-safe composite edible coating of hydrocolloids with papaya leaf extract improves postharvest quality and shelf life of papaya fruit under ambient storage.

Papaya postharvest management using low-temperature storage is discouraged as it is a tropical fruit. Extensive research is going on to preserve papaya quality at ambient storage using edible coatings and its composites. The present investigation examined the effects of an eco-safe composite edible coating consisting of hydrocolloid carboxymethyl cellulose (CMC) (1%), guar gum (1.5%), xanthan gum (0.3%), and Gum Arabic (10%) combined with papaya leaf extract (PLE) (1:1 ratio by volume) applied as dip treatment on "Red Lady" papaya fruit at ambient storage condition. Among all the attempted treatments, "PLE incorporated with CMC (1%)" was found to be the best, as the treated fruit exhibited the highest levels of biochemicals, whereas the lowest levels of physiological and enzymatic activity, which positively affected the shelf life. The "CMC + PLE" treatment enhanced the fruit gloss score by 70.1%, phenolics by 6.1%, ascorbic acid by 22.3%, total carotenoid content by 7.4%, and fruit predilection score by 22.0% over the control fruit. However, it lowered (controlling) the physiological loss in weight by 51.0%, decay incidence by 66.6%, and polygalacturonase and pectin methylesterase activity by 24.92% and 35.29%, respectively, over control. Moreover, this treatment exhibited the highest fruit purchase predilection score and prolonged the storage life for >3 days on the physiological loss standard basis (≤10%). This study indicates that "CMC (1%) with PLE (1:1)" composite coating application on papaya under ambient conditions might be an effective, environmentally friendly, and health-friendly way to retain the quality and extend the storage life.

Effect of walnut consumption on markers of endothelial function in adults: A systematic review and meta-analysis of randomized controlled trials.

Findings on the effect of walnut consumption on endothelial function are conflicting. Therefore, the present systematic review and meta-analysis summarized available trials in this regard. A systematic search was performed in online databases including PubMed-Medline, Scopus, and ISI Web of Science up to October 2023. Articles that reported the effect of walnut intake on flow-mediated dilation (FMD), intercellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1), and stimulus-adjusted response measure (SARM) were included. Random effects models for a weighted mean difference (WMD) or standardized mean difference (SMD) were used to test for the overall effect. Six eligible trials were analyzed (250 participants). Walnut intake significantly increased FMD (WMD: 0.94%, 95% CI: 0.12 to 1.75; p = 0.02). However, meta-analysis could not show any beneficial effect of walnut intake on ICAM-1 (SMD: -0.23, 95% CI: -0.68 to 0.22; p = 0.31), VCAM-1 (SMD: -0.02, 95% CI: -1.38 to 1.34; p = 0.97), and SARM (WMD: 0.01%, 95% CI: -0.01 to 0.04; p = 0.28). In conclusion, the present meta-analysis suggests that walnuts may reduce cardiovascular disease risk by improving FMD. However, further studies should be performed on adults to determine the effect of walnut intake on endothelial function.

Simple and Cost-effective Synthesis of a Rare-earth Free Long Afterglow Phosphor for Dark Visual Markings.

Materials with long afterglow (LAG) became very renowned in the field of luminescence due to their high ability to store energy. However, the development of LAG phosphors is mostly dependent on rare-earth activators, which are commercially expensive due to their limited availability across the world. On the other hand, LAG phosphors that are not based on rare-earth and are developed as an alternative cannot compete with existing rare-earth LAG phosphors. Copper-doped zinc sulfide (ZnS:Cu) phosphor developed long ago has considerable afterglow, but its development has been too tedious, and expensive, and contains usage of toxic gasses such as H2S, CS2, etc. and most of the literature refers to the cubic phase of ZnS. To overcome these issues and simplify the process, we have developed a cost-effective approach to synthesize the hexagonal phase of ZnS, without the involvement of hazardous gases. This is one of the very few reports that highlights the appearance of LAG phenomenon from the hexagonal ZnS:Cu phosphor system. Structural, morphological, and optical studies of the developed ZnS:Cu LAG phosphor have been carried out. The phosphor showed a strong green photoluminescence at 515 nm and an afterglow duration of ~ 1 h useful for specific applications of visual markings in dark conditions. The thermoluminescence spectrum shows a broad and intense glow peak at 377.15 K that indicates the electron trap depth to be at 0.75 eV, supporting our afterglow results.

Radioactive seed localization is a safe and effective tool for breast cancer surgery: an evaluation of over 25,000 cases.

Radioactive seed localization (RSL) provides a precise and efficient method for removing non-palpable breast lesions. It has proven to be a valuable addition to breast surgery, improving perioperative logistics and patient satisfaction. This retrospective review examines the lessons learned from a high-volume cancer center's RSL program after 10 years of practice and over 25 000 cases. We provide an updated model for assessing the patient's radiation dose from RSL seed implantation and demonstrate the safety of RSL to staff members. Additionally, we emphasize the importance of various aspects of presurgical evaluation, surgical techniques, post-surgical management, and regulatory compliance for a successful RSL program. Notably, the program has reduced radiation exposure for patients and medical staff.
