Raman Spectroscopy - An Analytical Tool for Biologics

Raman Spectroscopy (RS) is a non-invasive technique that analyses biomolecules qualitatively and quantitatively. Raman spectroscopy measures the inelastic scattering of light due to molecular vibrations. It can be applied to liquid, solid, or semi-solid forms of the biological sample reducing the sample preparation measures. The minimal sample preparation and non-invasive nature of Raman Spectroscopy can be applied in developing a Process analytical technology (PAT) tool and as a diagnostic tool. We demonstrated qualitative and quantitative measurements of biologics with Raman spectroscopy through our previous studies. Our results indicate that RS distinguishes various Gram-positive and Gram-negative bacteria, fungi, and a mixture of microbes and Chinese hamster ovary (CHO) cells. In addition, RS can determine the concentration of viral samples. We aim to optimize and refine Raman spectroscopy sensitivity by developing in-line probes and acoustic devices. Our future works also involve coupling Raman data with machine learning tools for accurate in-line measurements

Role of ‘One Stop Crisis Centre’ in Identifying and Assisting Victims of Violence in an Indian Health Care Setup

Introduction: Cases of female targeted violence often go uncounted in India. To identify the unreported cases of violence, Sukoon was established in 2014 as a hospital-based ‘One Stop Crisis Centre’ (OSCC). Sukoon provides counselling, police assistance and legal aid to the victims. The aim of the present study was to recognize the role of Sukoon in preventing violence against women (VAW) in the region.Methods: Secondary data was extracted from 430 victims who approached Sukoon from August 2014 through January 2017. Data was collected on different variables: age, marital status, nature of violence, medium through which victims approached Sukoon and type of assistance provided. Significance of association of studied factors with the type of assault was investigated using ?2 test.Results: Age of study-victims ranged from 4 to 75 years with a median age of 26 years and mean age of 27.61 years with standard deviation of 10.56 years. Major types of VAW (96.51%) were domestic violence, sexual assault, physical assault and poisoning. The types of violences were significantly associated with victims’ age (?2 =5.76, d.f.=1, p<0.05) and marital status (?2 = 98.23, d.f=4, p<0.001). About 78% of victims were identified from Sukoon through screening and counseling. Around 69% of the cases were resolved directly by Sukoon or through police assistance.Conclusion: The above results indicate a significant role of Sukoon in screening victims of violence and providing them required assistance within the hospital environment in one location. Such centers should be further promoted by the government to address the issues of VAW

Utilization of Stem Cells in Dentistry: A Review

For centuries, scientists have known that certain animals can regenerate missing parts of their bodies. Humans actually share this ability with animals such as starfish which has the ability to regenerate lost arms and can grow an entire new limb. Researchers define stem cells as the clonogenic cells with the capability of self renewal and multi-lineage differentiation and also have the capabilities of generating complex tissues and various organs

Awareness, Practice and Level of Anxiety using Coronavirus Anxiety Scale among the Indian Population regarding COVID -19 Pandemic

Abstract: The most important aspect of Public Health Emergency Preparedness (PHEP) involves the circulation of trustworthy and accurate information in the public health interest domain. Strict stringency measures such as nationwide lockdown impacted people's mental health. Hence, this study was planned to assess the knowledge, practice, and anxiety among the Indian population about the ongoing pandemic in the initial phase. Methods: A web-based cross-sectional study was conducted between August 1, 2020, to October 5, 2020. Coronavirus Anxiety Scale was used to determine dysfunctional anxiety. Results: Among 553 participants, 73.6% had overall good knowledge of COVID-19 with mean correct score of 6.9±1.1. Majority of participants (97%) wore mask regularly, and 93% of respondents regularly washed their hands with soap and water. Only 14 participants scored ?9 on CAS, suggesting probable cases of dysfunctional anxiety associated with the COVID-19 crisis. Conclusion: The knowledge and practices of citizens in a nation reflect their preparedness and ability to deal with a pandemic of such proportion. Good knowledge translates to good practices and therefore reduces anxiety among the population. It is deemed necessary that people's knowledge and habits, including the mental impact, be accessed at periodic intervals to track their adaptation to pandemics over time

Robust estimation of bacterial cell count from optical density

Optical density (OD) is widely used to estimate the density of cells in liquid culture, but cannot be compared between instruments without a standardized calibration protocol and is challenging to relate to actual cell count. We address this with an interlaboratory study comparing three simple, low-cost, and highly accessible OD calibration protocols across 244 laboratories, applied to eight strains of constitutive GFP-expressing E. coli. Based on our results, we recommend calibrating OD to estimated cell count using serial dilution of silica microspheres, which produces highly precise calibration (95.5% of residuals <1.2-fold), is easily assessed for quality control, also assesses instrument effective linear range, and can be combined with fluorescence calibration to obtain units of Molecules of Equivalent Fluorescein (MEFL) per cell, allowing direct comparison and data fusion with flow cytometry measurements: in our study, fluorescence per cell measurements showed only a 1.07-fold mean difference between plate reader and flow cytometry data

One breath at a time : a feasibility study

Measuring vital signs is crucial in healthcare as they provide essential information about a human body's physiological state. Particularly, the initial months following birth are crucial for the survival and well-being of newborns. Existing methods face challenges such as estimating incorrect respiratory rate values in low-light conditions, the inability to detect shallow breathing, overestimating respiratory values in darker skin tones and the need for contact sensors that may disturb sensitive infants. In this study, we propose a novel video-based respiratory rate estimation method for infants in the Neonatal Intensive Care Unit. Our method overcomes challenges by utilizing non-contact depth-sensing camera technology, which mitigates the impact of skin pigmentation on measurement accuracy. We conducted a study with 13 infants, recording uninterrupted 4-hour video sessions. We evaluated the algorithm's performance and robustness in various light conditions by analyzing randomly selected videos. We compared the respiratory rate estimated by our depth-sensing camera method with both a nurse practitioner's manually annotated reference respiratory rate and the respiratory rate estimated from red-green-blue (RGB) videos of the infants recorded during the same period as the depth videos. Our results record a bias of 0.125 bpm and a root mean squared difference accuracy of 1.058 bpm. Moreover, our proposed method exhibits a 26% increase in accuracy compared to the RGB camera-based method for respiratory rate estimation in infants. The Pearson correlation coefficient of 0.87 (p < 0.001) indicates a strong correlation, and the intraclass correlation coefficient of 0.77 (95%CI: 0.68 - 0.84 ) demonstrates good reliability. The Bland-Altman analysis of the proposed algorithm shows higher agreement between the values estimated by our developed method and the visually counted respiratory rate than the agreement between the respiratory rate obtained from the impedance sensors and the reference respiratory rate, the agreement between a former EVM-based method, and the respiratory rate estimated during the RGB-camera-based study. Our preliminary study shows that the proposed algorithm can successfully estimate the respiratory rate in the regular clinical care environment.Applied Science, Faculty ofElectrical and Computer Engineering, Department ofGraduat
