ANTI INFLAMMATORY EFFECT OF CIPROFLOXACIN, AZITHROMYCIN AND DICLOFENAC SODIUM ON CARRAGEENAN INDUCED HIND PAW EDEMA IN MICE

Background: Obviously, antibacterial agents are primarily directed against bacteria. However, because microorganisms can initiate an exaggerated inflammatory reaction, and as pathogens which persist in cryptic reservoirs (cells or granuloma tissue) can be the underlying cause of chronic inflammation, the hypothesis that antibacterials can down regulate inflammation. Methodology: Healthy adult mice weighing 20 - 30 g and aged 6-8 weeks, each group 6 mice were included. 1% carrageenan administered to produce inflammation. Grouping: Group 1: Normal saline 0.2 ml. i.p., Group 2: Diclofenac sodium 25mg/kg, Group 3 Ciprofloxacin 50 mg/kg, Group 4: Azithromycin 20mg/kg. Drugs were administered Intra Peritoneal. After 30 min of test drugs administration each group of mice were received subplantar administration of 0.05ml of saline (Control) or 0.05ml carrageenan (1%) for test groups 2 to 4. Paw volumes were measured by dipping in to the mercury plethysmograph at 30, 60, 120 and 180 minutes and results were tabulated. Results: Diclofenac, ciproflaoxin, Azithromycin inhibited paw edema in % at 30min 42.85, 28.55, 14.28, at 60min 75, 50, 25, at 120min 71.42, 42.85, 14.28, and at 180 min 50, 50, 25 respectively. Conclusion: Ciprofloxacin (50mg/kg) has exhibited consistent anti-inflammatory, but the anti-inflammatory activity of is less than that of Diclofenac sodium and Azithromycin also has exhibited anti-inflammatory activity, though much less when compared to Diclofenac sodium and Ciprofloxacin.

Irritation fibroma of tongue: a case report

Reactive hyperplastic outgrowths are seen in the oral cavity due to chronic irritation by plaque, calculus, overhanging margins, trauma and dental appliances.  Irritation fibroma represents a reactive focal fibrous hyperplasia due to trauma or local irritation. We report a case of irritation fibroma of right lateral border of tongue in a 46-year-old female

Systemic Inflammation and the Increased Risk of Inflamm-Aging and Age-Associated Diseases in People Living With HIV on Long Term Suppressive Antiretroviral Therapy.

The ART program in low- and middle-income countries (LMIC) like India, follows a public health approach with a standardized regimen for all people living with HIV (PLHIV). Based on the evidence from high-income countries (HIC), the risk of an enhanced, and accentuated onset of premature-aging or age-related diseases has been observed in PLHIV. However, very limited data is available on residual inflammation and immune activation in the populations who are on first-generation anti-HIV drugs like zidovudine and lamivudine that have more toxic side effects. Therefore, the aim of the present study was to evaluate the levels of systemic inflammation and understand the risk of age-associated diseases in PLHIV on long-term suppressive ART using a large number of biomarkers of inflammation and immune activation. Blood samples were obtained from therapy naïve PLHIV (Pre-ART, = 43), PLHIV on ART for >5 years (ART, = 53), and HIV-negative healthy controls (HIVNC, = 41). Samples were analyzed for 92 markers of inflammation, sCD14, sCD163, and telomere length. Several statistical tests were performed to compare the groups under study. Multivariate linear regression was used to investigate the associations. Despite a median duration of 8 years of successful ART, sCD14 ( < 0.001) and sCD163 ( = 0.04) levels continued to be significantly elevated in ART group as compared to HIVNC. Eleven inflammatory markers, including 4E-BP1, ADA, CCL23, CD5, CD8A, CST5, MMP1, NT3, SLAMF1, TRAIL, and TRANCE, were found to be significantly different ( < 0.05) between the groups. Many of these markers are associated with age-related co-morbidities including cardiovascular disease, neurocognitive decline and some of these markers are being reported for the first time in the context of HIV-induced inflammation. Linear regression analysis showed a significant negative association between HIV-1-positivity and telomere length ( < 0.0001). In ART-group CXCL1 ( = 0.048) and TGF-α ( = 0.026) showed a significant association with the increased telomere length and IL-10RA was significantly associated with decreased telomere length ( = 0.042). This observation warrants further mechanistic studies to generate evidence to highlight the need for enhanced treatment monitoring and special interventions in HIV-infected individuals

Targeting transcription regulation in cancer with a covalent CDK7 inhibitor

Tumour oncogenes include transcription factors that co-opt the general transcriptional machinery to sustain the oncogenic state, but direct pharmacological inhibition of transcription factors has so far proven difficult. However, the transcriptional machinery contains various enzymatic cofactors that can be targeted for the development of new therapeutic candidates, including cyclin-dependent kinases (CDKs). Here we present the discovery and characterization of a covalent CDK7 inhibitor, THZ1, which has the unprecedented ability to target a remote cysteine residue located outside of the canonical kinase domain, providing an unanticipated means of achieving selectivity for CDK7. Cancer cell-line profiling indicates that a subset of cancer cell lines, including human T-cell acute lymphoblastic leukaemia (T-ALL), have exceptional sensitivity to THZ1. Genome-wide analysis in Jurkat T-ALL cells shows that THZ1 disproportionally affects transcription of RUNX1 and suggests that sensitivity to THZ1 may be due to vulnerability conferred by the RUNX1 super-enhancer and the key role of RUNX1 in the core transcriptional regulatory circuitry of these tumour cells. Pharmacological modulation of CDK7 kinase activity may thus provide an approach to identify and treat tumour types that are dependent on transcription for maintenance of the oncogenic state.National Institutes of Health (U.S.) (Grant HG002668)National Institutes of Health (U.S.) (Grant CA109901

Racism detection using deep learning techniques

With the pervasive role of social media in the socio-political landscape, various forms of racism have arisen on these platforms. Racism can manifest in various forms on social media, both concealed and overt. It can be hidden through the use of memes or exposed through racist comments made using fake profiles to spread social unrest, violence, and hatred. Twitter and other social media sites have become new settings in which racism and related stress appear to be thriving. Racism also spread based on characteristics including dialect, faith, and tradition. It has been determined that racial animosity on social media poses a serious threat to political, socioeconomic, and cultural equilibrium and has even put international peace at risk. Therefore, it is crucial to monitor social media as the primary source of racist opinions dissemination and to detect and block racist remarks in a timely manner. In this study, we aim to detect tweets containing racist text by performing sentiment analysis using both ML and DL algorithms. We will also build a webpage using Flask framework and SQLite for users to interact with the model
