RESUMO
Background Forensic odontology has emerged as a crucial method for identifying skeletal or dental remains. Due to the restricted accuracy of current techniques for estimating age at death, researchers have endeavored to illustrate age-related alterations in dental hard tissues. Bone remodeling constitutes an ongoing and intricate process throughout our lifespan. It is believed that morphological changes in the mandible during an individual's lifetime are influenced by both dental condition and the individual's age. Objectives This study aims to evaluate the efficacy of mandibular parameters such as projective ramus height (PRH), maximum ramus breadth (MaRB), bigonial width (BGW), antegonial depth (Ant.D), and antegonial angle (Ant.A), as a gender-determining tool and compare and analyze the mandibular parameter measurements using digital orthopantomography. Methodology In this study, the total number of samples used was 500 out of which 250 were males and 250 were females. Planmeca software (Version 6.0, Planmeca Romexis, Charlotte, NC) was used and the accuracy test, analysis of variance (ANOVA), multiple regression, and discriminant analysis for gender were performed using SPSS for Windows, Version 16.0 (SPSS Inc., Chicago, IL). Results For age estimation, the least standard error of 0.008 was observed for BGW. A maximum standard error of 0.230 was observed for Ant.D. For sex determination, the coefficient function was positive for PRH, BGW, and Ant.A, with values of 0.202, 0.805, and 0.052, respectively. Ant.D and MaRB both exhibited negative values of -0.204 and -0.379, respectively. Conclusions Out of all the parameters assessed, BGW is the most preferred parameter for age estimation and Ant.A can be preferred for sex estimation. Age and gender can be estimated using the two parameters in the Indian population.
RESUMO
Aim and objective This study aims to assess the accuracy of gender estimation using gonial and antegonial angles and determine the gender of the given samples using gonial and antegonial angles. Introduction An essential component of the human skull, the mandible, exhibits sexual dimorphism, making it a valuable tool in forensic and anthropological investigations for detecting sex. This procedure can be especially difficult in situations where there are large numbers of casualties, natural disasters, or widely dispersed remains. The mandible is an accurate indicator of age and sex because it responds to patterns of growth. Sex determination through the gonial angle and antegonial angle involves analyzing the angles formed by the lower jaw bone in individuals. Examining these angles contributed to remarkable accuracy. Materials and methods A total of 500 samples, 250 male and 250 female panoramic radiographs, were carefully chosen for the study. The chosen samples ranged in age from 20 to 30 years. Orthophantomograms were measured in Planmeca software (Planmeca Romexis®, Version 6.0, USA INC.) and the descriptive statistics (paired t-test) were performed in SPSS Statistics version 16.0 (SPSS Inc. Released 2007. SPSS for Windows, Version 16.0. Chicago, SPSS Inc.). Results Gonial angle for males obtained the highest value of 127.27±5.29, followed by females at 127.08±5.18. This was followed by the antegonial angle for males of 10.74±3.14, and the least value was obtained by females of 10.67±3.30. The p-value for the gonial angle showed no statistical significance for males or females (p=0.679). Antegonial angle showed statistical significance in both males (p=0.008) and females (p=0.001). Conclusion Among both the parameters considered, the antegonial angle showed significance in determining the gender of the given samples. Hence, to assess the accuracy of gender estimation, the antegonial angle can be used as a parameter.
RESUMO
Forensic anthropology and forensic medicine both have been fascinating fields that deal with mandibular characteristics and sex determination. Researchers may determine an individual's biological sex with amazing precision by examining the size, shape, and proportions of the mandible. This information is useful for anthropological studies and criminal investigations. This systematic review aims to evaluate the consistency and validity of using mandibles as a method for gender determination across different populations. A systematic search was conducted in PubMed, Web of Science, and Scopus databases. Further, a manual search was carried out to find additional studies. Mandibular parameters and other relevant data about research were extracted from the included studies. Random effects meta-analysis was carried out for four parameters. A total of nine studies were included in the systematic review out of 76 initial search results. All studies were in vitro. Nine studies were included in the qualitative analysis, whereas only seven studies were included in the meta-analysis. A total of 2385 individuals (1193 male and 1192 female) were evaluated in the included studies. The parameters assessed were as follows: minimum ramus breadth (MiRB), maximum ramus breadth (MaRB), projective ramus height (PRH), bigonial width (BGW), gonial angle (GA), and antegonial angle (AGA). Meta-analysis was conducted for four parameters out of six. For the two parameters, meta-analysis was not conducted as only one study was evaluated. Meta-analyses of PRH obtained a high degree of heterogeneity (99%), mean difference (MD) of 4.06 mm, and p-value of p=0.09. Meta-analysis of BGW obtained 93% heterogeneity, MD of 9.03 mm, and p=0.0007. Meta-analysis of GA showed 99% heterogeneity, MD of 3.44 mm, and p=0.66. Meta-analysis of AGA obtained a low heterogeneity of 30%, MD of -0.77 mm, and p=0.23. The parameter, BGW, can be considered a useful tool in identifying sex. The parameters, PRH, GA, and AGA, cannot be preferred as a reliable tool in identifying the sex of an individual in forensic contexts.
RESUMO
Background Gender determination is critical to forensic science and medico-legal applications. Given that it is the most dimorphic bone in the skull and is frequently found intact, the mandibular bone may be extremely important in determining gender. Orthopantomograms (OPGs) are quite helpful in accurately estimating age and sex in this regard. It is a laborious task for forensics to determine the gender of victims of mass casualties, natural disasters, and severely dismembered bodies. The mandible, which is susceptible to development spurts, has a high degree of accuracy for determining sex. Aim This study aims to evaluate the potential use of coronoid height and condylar height as reliable anatomical markers for determining gender. Materials and methods In this study, 100 samples were used as study samples, 50 of which were male and 50 of which were female, in the age group of 20-30 years. The OPGs were obtained using a Planmeca Promax Scara 3 Digital OPG Machine (Planmeca, Helsinki, Finland), with settings of 70 kVp, 8 mA for 0.9 seconds, ensuring a 1:1 ratio. The images were then transferred to Planmeca Romexis® Viewer Software, Version 6.0 (Planmeca Oy, Helsinki, Finland) for measurement recording. Results Descriptive statistical analysis was done for this study and discriminant analysis was also done to create a population-specific formula. Results showed that the standard mean error for males concerning condylar height was 2.3 and coronoid height was 0.7. The standard mean error for females by condylar height was 1.6 and coronoid height was 0.6. The p-value was significant for coronoid height in both males and females. The p-value was not clinically significant for condylar height in both males and females. Conclusion The study's findings indicate that a larger mandibular angle is advantageous for gender assessment and helps with gender dimorphism. Out of both the parameters evaluated, coronoid height has shown statistical significance in both males and females. Hence, the study concludes that the parameter, coronoid height can be utilized to assess the gender of an individual.
RESUMO
Introduction The mandible constitutes one of the skull's largest and strongest bones. Growth spurts can influence it, and it has a variety of dimorphic traits that can be used to identify sex. In addition to observing, comparing, and evaluating the potential for mandibular ramus flexure and bigonial breadth to discriminate between sexes using digital orthopantomograms (OPG), a retrospective study was conducted to examine the validity of this method for sex estimation in the Indian population. Aim and objective This study aims to quantify sexual dimorphism by analyzing two mandibular parameters, the ramus flexure and the bigonial width, using orthopantomography (OPG). The objective is to determine the accuracy of sex determination using the ramus flexure and bigonial width. Materials and methods A total of 500 OPG images (250 males and 250 females) were analyzed using the Planmeca software (Helsinki, Finland). The ramus flexure was measured as the angle formed between the tangent to the inferior border of the mandible and the tangent to the posterior border of the ramus. The bigonial width was measured as the distance between the left and right gonion points. A statistical analysis was performed to assess sexual dimorphism and determine the accuracy of sex determination using these parameters. The study employed descriptive statistics, such as means and standard deviations, and an independent t-test to determine the significance of the characteristics in relation to males and females. Results The mean bigonial width for females was 193.3068 mm (SD = 13.51669 mm) and for males was 217.6308 mm (SD = 10.87453 mm), with a statistically significant difference (p = 0.000). The 95% confidence interval for the difference in the bigonial width between males and females was between -49.97173 mm and -43.93787 mm. For the ramus flexure, the mean was 0.0000 for both males and females (SD = 0.00000), with a significant difference between males and females (p = 0.003). The 95% confidence interval for the difference in the ramus flexure between males and females was between -0.59543 and -0.12457. Conclusion The results indicated significant sexual dimorphism in both the ramus flexure and bigonial width. This study demonstrated that the ramus flexure and bigonial width, measured using orthopantomography (OPG), exhibited significant sexual dimorphism. The analysis of these mandibular parameters provided valuable information for sex determination in forensic and anthropological contexts.
RESUMO
Background The study highlights the gonial angle as a key craniofacial landmark for age and gender determination in forensic cases. It emphasizes population-specific analysis, enhancing precision by recognizing variations between populations. By clarifying the gonial angle's forensic use, the study offers clear guidelines, improving forensic practices. Moreover, the gonial angle and age and gender correlations are thoroughly examined, offering important information on their forensic relevance. The results highlight how crucial population-specific research is to improving the precision and dependability of forensic age and gender estimation techniques, which advances forensic anthropology and supports forensic investigations around the globe. Aim and objective The purpose of this study is to assess the accuracy of age and gender estimates using gonial angles. The objectives of this research are to evaluate the precision of age and gender estimates utilizing the gonial angle. Materials and methods This present study comprises two groups based on age groups: Group I belongs to 51 to 60 years of age, and Group II belongs to 61 to 70 years of age. Making use of G-Power software (version 3.1.9.4, Düsseldorf, Germany), the sample size was determined. The calculation ensured 95% statistical power at a significance level (alpha error probability) of 0.05. To achieve sufficient statistical power, a total of 1000 samples were included, with a projected required sample size of 92. A total of 1000 samples, consisting of 500 male and 500 female panoramic radiographs, were meticulously selected for the study. The samples picked were within the age range of 51 to 70 years. Orthopantomograms were determined using Planmeca software (Planmeca Romexis®, Version 6.0, USA Inc.). Descriptive statistics, including prediction classification analysis of age and gender, were conducted using SPSS Statistics version 16.0 (SPSS Inc., Released 2007, SPSS for Windows, Version 16.0, Chicago, SPSS Inc.). Results According to this study, the mean gonial angle of males aged 51 to 60 years is larger (124.7370 degrees) than that of females (119.6371 degrees). The female group's mean estimates are more accurate, as seen by the smaller standard error (0.20844) compared to the male group's (0.60998). A statistically significant difference in mean gonial angles between the genders is evident, with males having a larger gonial angle (p-value <0.001). In the age range of 61 to 70 years, the mean gonial angle of females is higher (128.4322 degrees) than that of males (124.0529 degrees). In this instance, the male group's standard error is smaller (0.14968) than the female group's (0.30028), indicating more accurate mean estimates. Once more, a statistically significant difference is indicated by a p-value of less than 0.001, with females having a larger gonial angle than males. Conclusion Our study revealed that the gonial angle of the mandible can be considered a reliable parameter for gender identification. The study's limitation is its inability to reliably identify gender in the subadult population and in cases of edentulousness. An orthopantomogram is a trustworthy and accurate method for taking the different measurements needed to identify the gender of a particular mandible.
RESUMO
Introduction Determination of gender can be highly accurate with a complete adult skeleton, but in scenarios like mass disasters, only fragmented bones might be available. In such cases, identifying gender relies significantly on which parts of the skeleton are found. The mandible is a notably distinct bone in the skull and can be key in determining gender, especially when the entire skull is not available. The mandibular features provide clues that can help forensic experts determine the gender of an individual. Aim of the study This preliminary study aimed to determine the gender of an individual using mandibular parameters such as coronoid ramus height, condylar ramus height, projective ramus, minimum ramus breadth, and maximum ramus breadth. The objectives of this study were to (i) determine the gender of an individual using various mandibular parameters, (ii) evaluate the effectiveness of these mandibular parameters in distinguishing between male and female individuals, and (iii) establish a reliable method for gender identification based on the measured mandibular parameters. Materials and methods Since it was a preliminary study, the sample size calculation was done using G*Power software (Version 3.1.9.4; Heinrich-Heine-Universität Düsseldorf, Düsseldorf, Germany). The sample size was determined to guarantee a 95% statistical power at a significance level (alpha error probability) of 0.05. To ensure sufficient statistical power, a total of 100 samples were included, with a projected sample size of 92. A total of 100 samples, evenly split between 50 males and 50 females aged 20 to 30 years, were analyzed. Orthopantomograms (OPGs) showing pathologies, fractures, developmental disturbances of the mandible, and edentulous mandibles were excluded from the study. Statistical analysis was performed using SPSS for Windows, Version 16.0 (Released 2007; SPSS Inc., Chicago, IL, USA). Additionally, an accuracy test, analysis of variance (ANOVA), multiple regression, and discriminant analysis for gender were performed on individual data. Results In this study, five mandibular parameters were analyzed for gender such as coronoid ramus height, condylar ramus height, projective ramus, minimum ramus breadth, and maximum ramus breadth showed a positive correlation comparatively, and a novel formula was developed. Conclusion According to the present study, panoramic radiography can be considered a valuable tool in sex determination (with an accuracy of 90%), and all parameters of the mandible exhibited sexual dimorphism, showing they are reliable parameters with a total accuracy of 90%. However, coronoid ramus height, projective ramus, and maximum ramus breadth played a significant role in identifying gender in this particular study.
RESUMO
Aim This study aims to examine five mandibular parameters: coronoid ramus height, condylar ramus height, projective ramus height, minimum ramus breadth, and gonial angle, using orthopantomography (OPG). Introduction The mandible, a crucial part of the human skull, demonstrates sexual dimorphism, which makes it an important tool for determining sex in forensic and anthropological investigations. Its form and structure are relatively resistant to significant changes after death. Among all skeletal components, the mandible stands out as a primary indicator of sexual differences. In forensic investigations, establishing the age and sex of an individual is considered a crucial initial step. This process can be particularly challenging in scenarios involving mass casualties, natural calamities, or extensively fragmented remains. Due to its responsiveness to growth patterns, the mandible is adept at accurately determining both age and sex. Materials and methods This study employed a sample size of 500 individuals, split equally between males and females, with 250 participants each. The age bracket chosen for this cohort ranged from 20 to 30 years, considering that bone growth characteristics within this range can assist in sex determination. The height of the mandibular ramus was assessed using Planmeca software, and subsequent data analysis was conducted using SPSS. Results When estimating age, the condylar ramus height exhibited the smallest standard error (0.010), whereas the maximum standard error for the gonial angle was 0.028. Positive t values were observed for the gonial angle (1.182), minimum ramus breadth (0.114), and coronoid ramus height (0.733). In terms of determining sex, the gonial angle, coronoid ramus height, and projective ramus height demonstrated positive coefficient functions, specifically 0.676, 0.090, and 0.286, respectively. Conversely, both the minimum ramus breadth and the condylar ramus height displayed negative values of -0.385 and -0.126, respectively. Conclusion Among the parameters evaluated, condylar ramus height emerges as the most suitable choice for estimating age, while gonial angle, coronoid ramus height, and projective ramus height are preferable for determining sex.
RESUMO
Background Stress affects mental health significantly and is a ubiquitous feature of contemporary living. Among the possible antibiotics are omadacycline and vancomycin, whose anti-inflammatory properties have also been thoroughly documented in recent research. The goal of the current study was to examine their complex involvement in the brain's stress response circuits and how they modulate stress. An established model organism that provides a useful platform for examining stress-induced behaviors and possible therapeutic approaches is the zebrafish. To investigate how dopamine affects the stress response, we used a zebrafish model that was exposed to stress. Methodology For three minutes, zebrafish were continually subjected to chasing stress. They were then given antibiotic combinations of 50 µg/mL each of vancomycin and omadacycline at various ratios of 1:1, 3:1, and 3:1. Behavior alterations, including freezing bouts, top-bottom ratios, and latency periods, were analyzed and contrasted with control groups. ImageJ software was utilized to analyze the video footage of the fish. Results The study showed that the combination of omadacycline and vancomycin greatly reduced the behaviors in zebrafish caused by stress. They chose their concentration (50 µg/mL) according to the lethal concentration 50% result. By shortening the latency time and increasing the intensity of breezing sessions, these chemicals restored almost normal activity. There was statistical significance in the outcomes. The results show that the combination of vancomycin and omadacycline may have an anti-psychotic impact on zebrafish behaviors brought on by stress. Their control of stress reactions is consistent with their known roles in the reward and stress circuits of the brain. These results emphasize the complex interactions between neurotransmitter systems and the control of stress, highlighting the therapeutic potential of dopamine in the treatment of stress-related mental illnesses. Conclusions The combination of vancomycin and omadacycline has been shown to have anti-psychotic effects, which presents potential opportunities for the development of new treatment strategies for mental diseases associated with stress. To fully understand the specific processes underpinning their involvement in stress management and how they relate to mental illnesses in humans, more investigation is necessary.
RESUMO
Tumor epithelial development and chemoresistance are highly promoted by the tumor microenvironment (TME), which is mostly made up of the cancer stroma. This is due to several causes. Cancer-associated fibroblasts (CAFs) stand out among them as being essential for the promotion of tumors. Understanding the fibroblastic population within a single tumor is made more challenging by the undeniable heterogeneity within it, even though particular stromal alterations are still up for debate. Numerous chemical signals released by tumors improve the connections between heterotypic fibroblasts and CAFs, promoting the spread of cancer. It becomes essential to have a thorough understanding of this complex microenvironment to effectively prevent solid tumor growth. Important new insights into the role of CAFs in the TME have been revealed by recent studies. The objective of this review is to carefully investigate the relationship between CAFs in tumors and plant secondary metabolites, with a focus on thymoquinone (TQ). The literature published between 2010 and 2023 was searched in PubMed and Google Scholar with keywords such as TQ, TME, cancer-associated fibroblasts, mechanism of action, and flavonoids. The results showed a wealth of data substantiating the activity of plant secondary metabolites, particularly TQ's involvement in blocking CAF operations. Scrutinized research also clarified the wider effect of flavonoids on pathways related to cancer. The present study highlights the complex dynamics of the TME and emphasizes the critical role of CAFs. It also examines the possible interventions provided by secondary metabolites found in plants, with TQ playing a vital role in regulating CAF function based on recent literature.
RESUMO
The challenges in the management of human diseases are largely determined by the precision, speed and ease of diagnostic procedures available. Developments in biomedical engineering technologies have greatly helped in transforming human health care, especially for disease diagnosis which in turn lead to better patient outcomes. One such development is in the form of microfluidic chip technology which has transformed various aspects of human health care. We present in this review, a comprehensive account on the utility of microfluidic chip technologies for the diagnosis of autoimmune disorders, cardiovascular diseases (CVDs), infectious diseases, and neurodegenerative conditions. We have included the diseases posing global threat such as rheumatoid arthritis, diabetes, pernicious anemia, tuberculosis, COVID-19, influenza, alzheimer's, multiple sclerosis, and epilepsy. Apart from discussing the ways of microfluidic chip in diagnosis, we included a section presenting electrochemical, electrical, optical, and acoustic detection technologies for the precise diagnosis of CVDs. Microfluidics platforms have thus revolutionized novel capabilities in addressing the requirements of point-of-care diagnostics enabling miniaturization by integrating multiple laboratory functions into a single chip resulting in "one flow - one solution" systems. Hence, the precision and early diagnoses of diseases are now possible due to the advancements of microfluidics-based technology.

Parkinson's disease (PD) is a neurological condition that worsens with age (i.e., 1% of people over 65) with no permanent cure. Hence, finding a disease-modifying agent with fewer undesirable side effects is urgently needed. Parkinson's disease (PD) pathology results in the degeneration of dopaminergic (DAergic) neurons by accumulating lewy bodies, alpha-synuclein (-syn), lowering anti-oxidants, increasing neuronal inflammation, and altering neuron shape. A well-researched natural substance called Withania somnifera (WS) has a potent anti-oxidative, anti-inflammatory, and anti-neurodegenerative impact. WS, sometimes called as Indian Ginseng, is a subtropical undershrub of the Solanaceae family together with Ashwagandha. In the current work, EWSR's anti-inflammatory and neuroprotective efficacy was assessed in relation to rotenone-induced oxidative stress (i.e., LPO, CAT, and SOD and GSH), microglial activation, and neurodegeneration in the rotenone rat PD model. In ROT-induced brains, EWSR therapy resulted in a considerable decrease in LPO and increased levels of the antioxidants SOD, CAT, and GSH. Furthermore, our research showed that the intraperitoneal treatment of EWSR (40 mg/kg) in rotenone-induced rats reduced microglial activation and neuron loss in the substantia nigra (SN) and hippocampus caused by rotenone-induced neurotoxicity. Based on the observations, EWSR can be considered as an excellent source for neuroprotection, due to its significant anti-oxidative, anti-inflammatory, anti-neurodegenerative and anti-microglial properties when administered individually and in combination with known anti-inflammatory compounds (Doxycycline and Ellagic acids). But, further research is required before replacing the known neuroprotective treatments with phytochemical treatments.
RESUMO
Introduction Dopamine is an important neuroregulatory hormone and is secreted during exercise. Its role in physiological regulation is not fully uncovered. Recent studies showed that it suppresses inflammation. Colon cancer is one of the most predominant cancers in the population and is influenced by prolonged inflammation. The anti-inflammatory effect of dopamine using the colon cancer model was analyzed in KB cells. Methods KB cells were cultured using Dulbecco's Modified Eagle Medium and Inhibitory Concentration- 50 (IC50) was determined by 3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyl tetrazolium bromide assay. BCl-2, tumour necrosis factor-α (TNF-α), nuclear factor kappa- B (âââââNF-kB), and interleukin (IL)-6 were assessed using reverse transcription polymerase chain reaction (RT-PCR)(at 50 and 100 µg/ ml < IC50). Schrödinger was used for docking analysis using nuclear factor Kappa B (NF-kB) (Protein Data Bank: 5T8O) and dopamine (CID 681). Results Results were represented as mean ± standard deviation and statistically evaluated. Dopamine showed severe growth inhibition in KB cells (IC50- 225±3.1µg/ ml). It downregulated the expression of BCl-2, NF-k, and IL-6, but increased TNF-α expression. Dopamine bonded with NF-kB by two hydrogen bonds with aspartic acidââ-53and alanine-54, respectively). Conclusion The present study revealed that dopamine has a significant anti-cancer potential by blocking NF-kB pathways in KB cells.
RESUMO
Estradiol, a major form of estrogen, plays a crucial role in various aspects of brain function, including neuronal health, synaptic plasticity, and cognitive processes. Therefore, it is of interest to investigate the histopathological changes of the rat brain following estradiol treatment in unilateral and bilateral ovariectomized rats, a commonly used method to induce estrogen deficiency and study the consequences of hormonal changes. Two months old Wistar albino female rats were divided into five experimental groups, each consisting of 6 animals. Unilateral and bilateral ovariectomized rats were treated with estradiol (10 mg/Kg/b.wt) subcutaneously for 30 days. The histopathological analysis of brain revealed normal 5-6 compact layers of small pyramidal cells of CA3 region, most with vesicular nuclei in control rats andan irregular and disturbed thickness of the pyramidal cell layer in the CA3 region, suggesting neuronal loss in unilateral ovariectomized rats. Estradiol therapy to these rats showed dark hyperchromatic layers of pyramidal cells in the CA3 region, most of which displayed vesicular nuclei and less shrinkage. Bilateral ovariectomized rats without estradiol treatment showed irregular and disturbed thickness of the pyramidal cell layer in the CA3 region Similar to Group II, indicating neuronal loss and bilateral ovariectomized rats with estradiol treatment showed no significant changes. These findings highlight the potential role of estradiol in modulating the histopathological changes associated with ovariectomy. Further research is warranted to elucidate the underlying mechanisms through which estradiol exerts its effects on neuronal integrity and to explore potential therapeutic strategies for preventing or reversing these histological changes.
RESUMO
BACKGROUND: Work-related musculoskeletal disorders (WRMSDs) are one of the main causes of morbidity among healthcare professionals. It has various secondary consequences on productivity by diminishing the quantity and quality of work completed by the affected personnel, in addition to having a primary impact on the individual with pain and discomfort. OBJECTIVE: The study aims to determine the overall prevalence rate of WRMSD among dentists, physiotherapists, and surgeons and also identify the commonly affected regions of the body about specific health care professions among each of the three professions, as recorded by the cross-sectional studies performed in various countries and regions of the world. METHODS: A systematic search strategy was framed following the PRISMA guidelines based on the present inclusion and exclusion criteria. A critical search of articles was conducted during June 2020 in CINAHL (DOAJ), PubMed, Google Scholar Scopus, PEDro databases and SAGE journals. RESULTS: Out of the 42 articles that met the eligibility criteria, there were 39 cross-sectional studies, 2 pilot cross-sectional surveys and 1 prospective cohort study with one-year follow-up. All studies included in this review used various survey tools for recording the demographic details and measuring the prevalence of WRMSDs and other outcome factors. CONCLUSION: We conclude that all three health care professionals (dentists, physiotherapists and surgeons) are highly prone to develop WRMSDs with surgeons and dentists being more vulnerable when compared to physiotherapists. The lower back and neck are identified as the two most commonly affected regions among all three professionals.

BACKGROUND: In today's fast-paced world, both men and women have to be equally competent to handle their responsibilities in order to look after their family members and children. In this pace of competency women tend to forget to take care of their own health and face many health issues, including pelvic floor dysfunction. OBJECTIVE: This study aimed to analyse the prevalence rate of pelvic floor dysfunction among the working women in regards to their age and body mass index as well as their quality of life. METHODS: One hundred sixty one post-partum working female participants from the medical fraternity were involved in this study after their consent was obtained. Pelvic floor muscle strength was assessed and their quality of life measured using King's health questionnaire. RESULTS: There was a strong correlation between the pelvic floor muscle dysfunction and its impact on the quality of life among the females with increasing age. Significant statistical significant difference of P(<0.0001) was noted. CONCLUSION: Pelvic floor dysfunction among females has a direct impact on their quality of life.

Circadian rhythms (CRs) are fundamental biological processes that significantly impact human well-being. Disruption of these rhythms can trigger insufficient neurocognitive development, insomnia, mental disorders, cardiovascular diseases, metabolic dysfunctions, and cancer. The field of chronobiology has increased our understanding of how rhythm disturbances contribute to cancer pathogenesis, and how circadian timing influences the efficacy of cancer treatments. As the circadian clock steadily gains recognition as an emerging factor in tumorigenesis, a thorough and comprehensive multi-omics analysis of CR genes/proteins has never been performed. To shed light on this, we performed, for the first time, an integrated data analysis encompassing genomic/transcriptomic alterations across 32 cancer types (n = 10,918 tumors) taken from the PanCancer Atlas, unfavorable prognostic protein analysis, protein-protein interactomics, and shortest distance score pathways to cancer hallmark phenotypes. This data mining strategy allowed us to unravel 31 essential CR-related proteins involved in the signaling crossroad between circadian rhythms and cancer. In the context of drugging the clock, we identified pharmacogenomic clinical annotations and drugs currently in late phase clinical trials that could be considered as potential cancer therapeutic strategies. These findings highlight the diverse roles of CR-related genes/proteins in the realm of cancer research and therapy.

The most complex and important portion of the body and masticatory system are the temporomandibular joint. The growth of mandibular bone in both sagittal and vertical directions is by the condylar process. This study is done to determine different shapes of mandibular condyles using orthopantomographs (OPGs). The study's goal was to determine the morphology of the mandibular condyle in South Indians. One hundred digital OPGs with no defects were selected and obtained from private dental institutes and hospitals in Chennai for this study. The morphology of the mandibular condyle was studied and tabulated. Using the SPSS software, the Chi-square test was done to find associations between demographics and morphology. The study was an attempt to find the prevalent shape of the condylar head using a panoramic radiograph. Fifty-one percent were oval in shape, 20.5% were bird beak in shape, 13.6% were diamond in shape, and 14.9% were crooked finger in shape. The results suggest an oval-oval shape in more frequency among both genders. OPGs are the most commonly used and interpreted radiographs, due to their low radiation and easy availability among dentists. Hence, the shape of the mandibular condyle can also be determined using OPGs; future studies are to be conducted in large samples to make the context evident.
RESUMO
BACKGROUND: Burnout is a state of emotional, physical, and mental exhaustion caused by excessive stress. Burnout weakens the energy of an individual which reduces productivity and leaves this individual helpless, hopeless, cynical, and resentful. Thus, an early diagnosis of this syndrome has to be done and ways to prevent the level of progression and complication of burnout syndrome has to be planned. OBJECTIVE: To determine the efficacy of self-supervised Jacobson's relaxation technique along with Bhastrika Pranayama in reducing the level of burnout among the work-from-home IT professionals during the COVID-19 pandemic. METHOD: Thirty participants with burnout syndrome were randomly divided into two groups (15 participants in each group) using random allocation. The experimental group received Jacobson's relaxation technique along with Bhastrika Pranayama, whereas the control group received diaphragmatic breathing exercises and chest expansion exercises. Pre-test and post-test values using Maslach Burnout Inventory were used to interpret the results. RESULTS: Data collected were analyzed statistically by the Wilcoxon Signed Rank Test. It shows that there is a significant reduction in the level of burnout in the experimental group when compared to the control group at a p-value of 0.001. CONCLUSION: From the results, it is concluded that Jacobson's relaxation technique along with diaphragmatic breathing exercises showed significant improvement in the reduction of burnout levels.

Cranial base tactics comprise the regulation of tiny and complicated structures in the domains of otology, rhinology, neurosurgery, and maxillofacial medical procedure. Basic nerves and veins are in the nearness of these buildings. Increased the truth is a coming innovation that may reform the cerebral basis approach by supplying vital physical and navigational facts brought together in a solitary presentation. In any case, the awareness and acknowledgment of prospective results of expanding reality frameworks in the cerebral base region are really poor. This article targets examining the handiness of expanded reality frameworks in cranial foundation medical procedures and emphasizes the obstacles that present innovation encounters and their prospective adjustments. A specialized perspective on distinct strategies used being produced of an improved realty framework is furthermore offered. The newest item offers an expansion in interest in expanded reality frameworks that may motivate more secure and practical procedures. In any case, a couple of concerns have to be cared to before that can be for the vast part fused into normal practice.
