Introduction: Cervical spinal cord injuries (CSIs) account for 2% - 3% of trauma cases and 8.2% of trauma- related fatalities, making them a significant cause of disability and mortality. Effective management and timely interventions are essential to improve neurological and functional outcomes. This study aimed to evaluate the outcomes of patients with CSIs and identify key predictors of neurological and functional improvement.Materials and methods: This prospective observational study was conducted over 12 months at SMS Medical College, Jaipur, involving 100 patients with CSIs from C1 to C7 vertebrae. Patients presenting within one week of injury were included. Clinical evaluation was conducted using the ASIA scoring system, and functional outcomes were assessed with the Functional Independence Measure (FIM) scale. MRI findings were analyzed to classify injuries and identify critical predictors, including the presence and extent of edema and listhesis grading.Results: Significant predictors of neurological improvement included injury type, management approach, MRI findings, extent of edema (≤ 2 vs. >2 segments), and listhesis grading. Operative management and incomplete injuries showed better outcomes. The median Barthel Index improved from 4.0 preoperatively to 7.0 at four months (p < 0.001). The mean FIM score also significantly increased from 43.25 ± 26.5 to 56.8 ± 40.75 (p < 0.05). ASIA Grades C and D demonstrated significant neurological recovery, with no grade deterioration observed.Conclusion: Age, injury type, management strategy, MRI findings, extent of edema, and listhesis grading are key predictors of outcomes in CSIs. These findings emphasize the importance of early diagnosis, timely surgical intervention, and comprehensive management in improving neurological and functional recovery. Multicentric studies with larger cohorts are recommended for broader generalizability.

Melanoma is a highly malignant neoplasm arising from melanocytes, which are melanin-producing neural crest cells primarily located in the basal layer of the epidermis, making cutaneous melanoma the most common subtype. However, melanocytes are also found in other anatomical locations, and primary non-cutaneous melanomas, though rare, have been documented. Due to the aggressive nature of this malignancy, it carries a poor prognosis, particularly because it tends to metastasize to various, often atypical, sites. Recognizing these variable presentations is essential for timely diagnosis. Here, we report a rare case of metastatic brain melanoma in a young female and review the relevant literature, highlighting the importance of imaging in identification.
Background: To enhance the duration of sensory anaesthesia and to prolong the duration of post-operative pain relief during spinal anaesthesia, various adjuvants have been tried along with local anaesthetic agent. The present study was undertaken to evaluate and compare the onset and duration of sensory block, motor block and duration of post-operative pain relief by using intrathecal 0.5% Hyperbaric bupivacaine with fentanyl 25µg versus only 0.5% Hyperbaric bupivacaine selected groups.Methods: We enrolled 70 ASA Ι & ΙΙ patients undergoing surgeries below umbilicus level for our Prospective Randomized trial. Those who met our inclusion criteria were randomized using simple random sampling technique, after obtaining informed consent. Patients in Group A received fentanyl 25µg with 0.5% Hyperbaric Bupivacaine and patients in Group B received only 0.5% Hyperbaric Bupivacaine intrathecally. Parameters like onset and duration of sensory and motor block and postoperative pain relief were observed. In postoperative period, VAS score was monitored & time for rescue analgesia was noted, when VAS exceeded 5 or above.Results: It was found that Patients in Group A had significantly prolonged duration of postoperative analgesia as compared to Group B (Z value 17.35). Results of Onset & Duration of sensory and motor block were suggesting insignificant result. Post-operative complication was insignificant in our study.Conclusion: Addition of Fentanyl 25µg with 0.5% Hyperbaric Bupivacaine in Spinal anaesthesia have insignificant effect on duration of sensory and motor blockade and prolongs postoperative pain relief.
Pachydermoperiostosis, also known as Primary Hypertrophic Osteoarthropathy (PHO), is a rare genetic disorder. The three main features are: enlarged fingertips (clubbing), thickened facial skin (pachydermia), and excessive sweating (hyperhidrosis). PHO is characterized by problems with skin and bone growth. Patients with PHO usually have coarse facial features with oily, thick, grooved skin on the face, joint pain, enlarged fingertips and toes, and hyperhidrosis of the hands and feet. Symptoms vary individually; however, men generally present with more severe manifestations. X-rays can help check for features that are not noticeable to the naked eye. There are two genes that are associated with PHO: the HPGD gene, located on the long arm of chromosome 4 at 4q34.1, and the SLCO2A1 gene, located on the long arm of chromosome 3 at 3q22.1 - q22.2. Mutations in the HPGD gene are inherited in an autosomal recessive manner, and the condition is sometimes abbreviated as PHOAR1 or Touraine-Solente-Gole syndrome.
Polymer Electrolyte Membrane Fuel Cells (PEMFCs) operating in Dead-Ended Anode (DEA) mode present a promising alternative to traditional flow-through systems by simplifying design and reducing costs. However, their efficiency and durability are challenged by transient phenomena such as water accumulation, nitrogen buildup, and carbon corrosion throughout operation. This review investigates the dynamic behavior of DEA PEMFCs under dynamic operating states, aiming to improve their efficiency. By analyzing purge cycle optimization and transient response characteristics, we identify strategies to mitigate hydrogen loss, maintain voltage stability, and extend stack lifetime. The key findings indicate that precise purge scheduling and effective water management are critical for optimizing performance, with dynamic models providing insights into time-dependent processes. This study underscores the potential of DEA PEMFCs for high-efficiency applications provided transient effects are effectively managed.
Touch DNA, the minute quantities of DNA deposited through skin contact, has become a valuable tool in forensic investigations. However, the recovery of touch DNA from non-porous surfaces remains a challenging task, requiring optimized collection and extraction techniques to maximize DNA yield, because non-porous surfaces have smooth, non-absorbing material properties. This review explores various non-porous surfaces such as glass, plastic, and metal, analyzing their impact on DNA recovery efficiency. Different collection methods, including swabbing, tape lifting, scrubbing, and vacuum collection methods, are evaluated to determine their effectiveness in retrieving minute amounts of DNA from these surfaces. Through a comparative analysis of existing studies, this paper identifies which collection methods work best for different non-porous surfaces and why choosing the right technique matters. Factors such as surface type, environmental conditions, and collection technique performed, time duration, and so on can affect DNA recovery, making it crucial to use the most effective approach. This review also emphasizes the need for standardized protocols to ensure consistent and reliable results in forensic investigations. Having clear guidelines can reduce errors, improve DNA analysis, and make touch DNA analysis more reliable in forensic investigations. By focusing on these aspects, this study aims to contribute to the ongoing efforts in refining touch DNA recovery strategies.
Objectives: Hospitalization following a head injury is associated with high rates of disability that have a strong correlation with depression, anxiety, and low self-esteem. Well-being is related to life satisfaction, quality of life, happiness, personal growth and flourishing, competence, self-acceptance, positive relationships, and autonomy. The well-being of patients and their primary caregivers is important when a patient is left with impaired mobility after neurosurgery. The aim of this study is to examine whether the well-being of patients and their primary caregivers will differ before and after neurosurgery, and whether well-being differs between patients with motor disability (WMD group) and those without, compared to those who are not - NMD group (non-motor disability).Methodology: 123 patients and their main caregivers were recruited. Of these, 62 were in the before neurosurgical group, 31 Patients and 31 caregivers. 61 in the after neurosurgical group, 30 Patients and 31 caregivers, of which there are 16 from WMD group and 15 from NMD. Main outcome measures: Two analyses of Variance (ANOVA) were conducted: for WMD and NMD separately. The results reveal a significant decrease in wellbeing for both, patient and main caregivers, but a stronger decline in well-being was observed among WMD, as indicated by a larger effect size (η² = 0.74) compared to the NMD (η² = 0.38). In addition, no significant effect between group and time of measurement was found, indicating that the decrease in wellbeing was not different among patients compared to their main caregivers. Conclusion: The findings highlight the multifaceted impact of neurosurgery on well-being, particularly for patients who remain with motor disabilities and their primary caregivers.The decline in well-being after neurosurgery highlights the need for improved social support and the importance of developing treatment programs that can help ease the process of coping with these phenomena and provide appropriate support for both patients and their primary caregivers.

Introduction: Flow analysis in the apical view of transthoracic echocardiography is validated to assess fluid responsiveness at the bedside. Still, it is not always reachable, especially in mechanically ventilated patients and during surgery. We compared it to supra-sternal and sub-xiphoid views to evaluate their validity in assessing fluid responsiveness in critically ill patients.Method: A cross-sectional prospective monocentric pilot study of three months duration has been led in the critical care unit for surgical emergencies of Ibn Sina University Hospital of Rabat (Morocco). We used the time-velocity index (VTI) and peak velocity variation (∆Vpeak) values correlation between the three acoustic windows as the main judgment criteria. Measurement of data was made in the Left Ventricle Outflow Tract (LVOT) in the 5-chamber apical view, Descending Thoracic Aorta (DTA) in the supra-sternal view, and Right Ventricle Outflow Tract (RVOT) in the sub-xiphoid view.Results: There were 14 adult patients involved in the study, and the data presented are preliminary results. There was no significant difference in VTI and ∆Vpeak values between the three acoustic windows at each time of the study protocol, with a very high correlation for initial VTI value between 5-chamber apical view and supra-sternal view (r = 0.96, p < 0.001), and sub-xiphoid view (r = 0.86, p < 0.001). A very high correlation of initial ∆Vpeak value was also observed between the 5-chamber apical view and supra-sternal view (rho = 0.89, p < 0.001) and sub-xiphoid view (rho = 0.79, p < 0.001).Discussion: Supra-sternal and sub-xiphoid views showed high potential to predict fluid responsiveness, but further data are needed to validate their use for this purpose in ICU and in operating room.
The examination and the survey of how a person moves, particularly the way of life of walking and running. It entails studying and quantifying a person's gait in terms of their stride length, cadence, foot position, and movement of various body joints. Wearable technology makes it possible to monitor the gait pattern continually while moving about freely. The direction line, gait line, foot line, foot angle, principle line, step length, step breadth, and displacement value obtained from the gyro and accelerated sensors coupled to the shank and thigh are all used to analyze the gait pattern. There has been a lot of research on this method of recognizing people by the way they walk.The two most crucial facts are that OpenPose, a 2D multi-person posture estimation library, can detect 135 critical body locations without the requirement for fiducial markers, and that smartphone cameras can detect the gait pattern without the use of physical markers. In addition, lower extremity sagittal joint angles, spatiotemporal gait parameters, and timings of gait events were independently determined for motion capture. Gait analysis systems use portable, readily available cameras to measure gait characteristics. The pace of gait, length of steps, time of steps, cadence of steps, and the period of stance are the most crucial factors. Recently, the top standard for the examination of gait was used to evaluate the schemes based on two camera usage to evaluate the framework of different gait patterns.The precision of the examination of SCA is being increased by data scientists through the development of AI-based computer algorithms. To increase individualization, Bertillon measured the body and faces of several convicts in 1883.
Aim: To compare the vision related quality of life before and after prescription of refractive glasses in school-aged children. Design: A prospective, comparative, and hospital-based interventional study was conducted at the Regional Institute of Ophthalmology, PGIMS, Rohtak between May 2021-May 2022. It involved assessment of vision-related quality of life (VRQoL) in 200 school-going children of the 5-16 age group, then comparing outcomes in children with URE versus those corrected with eyeglasses. Those with significantly low visual acuity (≤ 6/9) on Snellen’s were enrolled in the study after obtaining written informed consent from parents. The Modified SREEQ was used to assess VRQoL. Various parameters of comparison included age, gender, demography, education, and improvement in VRQoL within individual study groups over time. Comparison was done before and after using prescription refractive eyeglasses with a follow-up period of 3 months. Results: The correction amongst hypermetropes, 40 out of total 200 students (20%), correction among myopes (153 of 200 students), correction amongst students with astigmatism (7 out of 200 students) resulted in changing categories from mild/moderate/severe visual impairment to normal category of visual acuity i.e., 6/6 on immediate correction with refractive glasses prescribed to them post refraction. Students with astigmatism showed an improvement in symptoms like distorted images post-refractive correction at 3 months. Thus, proving a positive role of refractive eyeglasses in reducing the burden of refractive errors in our study population and improving the visual outcome. Conclusion: VRQoL was better in students after they got their refractive errors corrected with prescription eyeglasses at 3 months as compared to their QoL evaluated at their first visit to our centre with URE. This study focused on having a holistic approach towards improvement in QoL by taking into consideration the academic, psychological, cost-effectiveness aspects of VRQoL among students in the age group 5-16 years old.
The limits of classical equivalent computation based on time, dose, and fractionation (TDF) and linear quadratic models have been known for a long time. Medical physicists and physicians are required to provide fast and reliable interpretations regarding the delivered doses or any future prescriptions relating to treatment changes. In this letter, we propose an outline related to the different models usable for equivalent and biological doses that are likely to be the most appropriate. The used methodology is based on: the linear-quadratic-linear model of Astrahan, the repopulation effects of Dale, and the prediction of multi-fractionated treatments of Thames.
Biotechnology has always played an important role in tackling global concerns, particularly in the Global South, where socioeconomic gaps sometimes stymie scientific progress. Recent advances in synthetic biology and computational technologies have the potential to revolutionize biotechnology in these locations. Synthetic biology allows for the creation and manipulation of biological systems, with promise applications in healthcare, agriculture, and environmental control. Computational methods such as machine learning and artificial intelligence help to optimize synthetic biology processes, enabling innovations that are suited to local requirements. The combination of these cutting-edge technologies with traditional biotechnological techniques has the potential to dramatically improve the Global South's ability to solve issues such as disease outbreaks, food security, and sustainable development. This abstract outline the critical intersections of synthetic biology and computational advancements and their potential to empower the Global South, highlighting the need for supportive policies and capacity-building initiatives to maximize their impact.

In this work we are concerned with identifying visible evidence that can only be observed with the naked eye and is required for experiments by forensic scientists. The search details include many visible physical properties that could be used to explain many unknowns in the crime scene, which means critical truths for different cases. The details include appearance phenomena such as color, odor, shape, size, material type, and inferred properties based on physical appearance. The properties discussed in this work can be further analyzed using specific portable apparatuses that could give very important information about the structure and nature of the properties of evidence in a crime scene. We also deal in this work with general expertise, which forensic scientists should understand and could treat to make the process of identification and characterization in crime scenes be done more systematically in a short time.
Hereditary Hemochromatosis (HH) is an inherited recessive autosomal disorder characterized by the accumulation of excess iron. When iron-binding proteins become saturated, concentrations of free or Non-transferrin-bound iron (NTBI) rise, a condition thought to be responsible for the adverse effects associated with HH. To investigate whether disturbing iron homeostasis plays a role in free radical injury in HH, protein carbonyls were found to be 1-7 times higher in patients with HH than in controls, with the greatest increases observed in untreated HH patients with high ferritin and > 90% transferrin saturation with iron. An unpaired t-test revealed a p value of 0.0278 (p < 0.05), which is considered statistically significant.In vitro oxidation of transferrin standards with hydrogen peroxide and excess iron, followed by immobilized trypsin digestion (Poroszyme), high-resolution LC-MS/MS analysis (Q-TOF Ultima, Waters), and MS/MS data processing (PEAKS, Bioinformatics Solution), identified several tryptic peptides containing oxidized Methionine (Met), Tryptophan (Trp), and Histidine (His) residues. Using the same methodology, oxidized residues were subsequently detected in transferrin isolated from plasma samples of patients severely affected by HH. Comparison of MS/MS spectra of in vitro oxidized samples with the most fragment ion peaks in common with oxidized peptide MS/MS spectra from patient samples revealed a strong correlation between the two. These data show that elevated NTBI may be involved in the oxidative modification of transferrin and that such modifications may play a significant role in the pathophysiology of HH.
The role of free radicals and antioxidants is often underestimated despite their involvement in key metabolic processes, although they participate in many important metabolic processes in the life of humans, animals and plants. Their quantity and quality differ from each other, which is not respected. Each cell is attacked approximately 10,000 times by free radicals. Oxidative stress is the cause of many problems, especially in viral diseases. Monitoring of redox potentials in body fluids is usually not carried out. Viral replication is influenced by oxidative energy, derived from either host metabolism or free radical activity, which is supplied by oxidation by free radicals or the host. Nucleic acid mutations due to the effect of free radicals can be the cause of carcinomas, and possible defense against mutations could help eradicate dangerous viruses. The importance of malondialdehyde and antibodies against it is discussed. Eliminating free radicals, reducing lipoperoxidation, and protecting against environmental oxidative stress are important factors for human health.Study objective: To highlight the importance of free radicals, antioxidants and redox potentials for patient diagnosis and therapy.Methods: This study synthesizes findings from multiple published sources, including our own research.Results: Findings highlight the role of free radicals in oxidative stress, DNA damage, and viral replication, with redox potential (ORP) and Malondialdehyde (MDA) identified as key diagnostic markers.Conclusion: Monitoring oxidative balance and targeting free radical activity are essential for preventing cellular damage and improving clinical outcomes in oxidative stress-related diseases.
A specialized installation has been developed for microscopic study of the Reactive Oxygen Species (ROS) formation during microwave irradiation of biological samples with automated control / mechanized tube and real-time data acquisition. The above installation can be used in biomedical practice for: standardization or certification of the microwave sources; testing of the potential antioxidants that protect tissues from ROS-induced effects; testing fluorescent sensors for ROS; analysis of ROS localization and distribution in various tissues in order to establish specific pharmaco-physiotherapeutic and toxicological localizations of ROS in different topographic-anatomical zones. The paper pays special attention to the singlet oxygen produced by the samples upon microwave treatment, as a physiologically active and highly reactive agent.
Custard apple is a tropical fruit that is cultivated all over India. The seeds of this fruit are found to have medicinal properties as they contain active compounds such as alkaloids, cyclohexapeptides, and acetogenins. It has been used in powdered form for the treatment of scalp lice and dandruff in our part of the world as a native medicine for a long time. We report a case of bilateral severe toxic keratoconjunctivitis following accidental exposure to custard apple seed powder.
