    Abstract Arsenic (As) toxicity can generate reactive free radicals, which play an important role in the evolution of cardiomyopathy. The aim of this research is to see if sulforaphane (SFN) protects against As-induced heart damage, oxidative stress, and mitochondrial complex dysfunction via the PI3K/Akt/Nrf2 signaling pathway. The rats were placed into four groups, each with eight rats. Group 1: Normal rats (control group); Group 2: Treatment group (5 mg/kg body weight); Group 3: SFN+As-treatment group (80 mg/kg body weight + 5 mg/kg body weight); Group 4: SFN group only (80 mg/kg body weight). The swot will last 4 weeks. At the end of the intermission (28 days), all of the rats starved overnight and killed with cervical decapitation. As administration considerably (p < 0.05) inflated the extent of free radicals (O2-, OH-), lipoid peroxidation (malondialdehyde, 4-hydroxynonenal), lipoid profile (low-density lipoprotein-cholesterol, very low-density lipoprotein-cholesterol (VLDL-C), total cholesterol, triglyceride, and phospholipids), cardiac Troponin (cTnT&I), and Mitochondrial complex III. A noteworthy (p < 0.05) diminish the level of HDL-C, Mitochondrial complex I and II, enzymatic (superoxide dismutase, catalase, and glutathione peroxidase), and nonenzymatic antioxidant (glutathione and total sulfhydryl groups) and PI3k, Akt, and Nrf2 sequence in As treated rats. The western blot, real-time polymerase chain reaction, flowcytometric, and histology studies all corroborated the biochemical findings which revealed significant heart damage in rats. Pretreatment with SFN significantly (p < 0.05) reduced the invitro free radicals, lipid oxidative indicators, mitochondrial complex, lipid profiles, and increased phase II antioxidants in the heart. This result shows that dietary supplementation of SFN protects against As-induced cardiotoxicity via PI3k/Akt/Nrf2 pathway in rats.

    Abstract A new series of 8-nitroquinolone-based aromatic heterocyclic acyl hydrazones have been synthesised and characterised through various spectroscopic techniques. They were theoretically examined for molecular docking with various proteins related to the apoptosis of the non-small cell lung cancer cell line A549. The results indicate that the possible modes of interaction of all the synthesised compounds are compatible for use as anti-proliferative drugs. Also, the drug-likeness of the compounds was examined through theoretical ADMET analysis, which indicated good gastrointestinal absorption as well as low toxicity. Selected compounds were evaluated for their

    Abstract Cell-surface receptors are the inviters of many potent pathogens that can adjust to any kind of circumstance for their existence. Many of these organisms are highly resistant to the currently existing drugs and mutate to new strains with high levels of pathogenesis, posing life-threatening consequences. Owing to such concerns, antiviral strategies are being assessed based on host cell receptor targeting. Many natural compounds with a tendency to strip off the cell surface receptors are under evaluation. Compounds that are non-toxic, patient friendly, and yield a quick output are essential for the current scenario. Drugs targeting the cell surface receptors should, therefore, be developed and standardized for the effective management of SARS-CoV-2 viral infection.

    Abstract Triple negative breast carcinoma (TNBC) is an aggressive form of cancer, with high rates of morbidity, mortality, poor prognosis and limited therapeutic options. The objective of the present study was to elaborate the anticancer activity of Troxerutin (TXN) in TNBC/MDA-MB-231 cells. Herein, we demonstrated the inhibitory effects of TXN on the breast cancer cell growth via induction of apoptosis. Mitochondrial membrane potential (∆Ψm), DNA damage and apoptotic nuclear changes were analyzed by flowcytometry, AO/EtBr and Hoechst staining, respectively. Furthermore, apoptotic protein and gene expressions were analyzed by western blot and reverse transcription polymerase chain reaction (RT-PCR), respectively. Our results indicated that TXN induces apoptosis as evidenced by inhibit the cell proliferation, enhanced apoptotic activation, altered mitochondrial membrane potential and elevated level of DNA damage in TNBC cells. Furthermore, the TXN inhibit anti-apoptotic protein expression with the subsequent upregulation of Cytochrome c, Caspase-9 and Caspase-3. Thus, TXN induces apoptosis in TNBC cells through inducing nuclear damage and altered apoptotic marker expressions. Therefore, TXN might be used as a potential therapeutic agent for the treatment of triple negative breast cancer.

    Abstract The studies on protein-dye interactions are important in biological process and it is regarded as vital step in rational drug design. The interaction of thionine (TH) with human serum albumin (HSA) was analyzed using isothermal titration calorimetry (ITC), spectroscopic, and molecular docking technique. The emission spectral titration of HSA with TH revealed the formation of HSA-TH complex via static quenching process. The results obtained from absorption, synchronous emission, circular dichroism, and three-dimensional (3D) emission spectral studies demonstrated that TH induces changes in the microenvironment and secondary structure of HSA. Results from ITC experiments suggested that the binding of TH dye was favored by negative enthalpy and a favorable entropy contribution. Site marker competitive binding experiments revealed that the binding site of TH was located in subdomain IIA (Sudlow site I) of HSA. Molecular docking study further substantiates that TH binds to the hydrophobic cavity of subdomain IIA (Sudlow site I) of HSA. Further, we have studied the cytotoxic activity of TH and TH-HSA complex on breast cancer cell lines (MCF-7) by MTT assay and LDH assay. These studies revealed that TH-HSA complex showed the higher level of cytotoxicity in cancer cells than TH dye-treated MCF-7 cells and the significant adverse effect did not found in the normal HBL-100 cells. Fluorescence microscopy analyses of nuclear fragmentation studies validate the significant reduction of viability of TH-HSA-treated human MCF-7 breast cancer cells through activation of apoptotic-mediated pathways.

    Abstract Lectins are proteins that show a variety of biological activities. Nevertheless, information on lectin from Gluttonous beauts and their anticancer activities are very limited. In this study, we purified a lectin from hemolymph of G. beauts and identified its molecular weight to be 66kDa. The effect of lectin at different concentrations (μg/mL) on the cell growth and apoptosis were evaluated against MCF-7 and MCF-10A cells, whereas cytotoxicity to the MCF-7 cells mediated by lectin was observed and the mechanism of action of the lectin in including apoptosis in cancer cells via the intrinsic pathway was also proposed. The MCF-7 cells were employed for in vitro studies on cytotoxicity, induction of apoptosis and apoptotic DNA fragmentation. In MCF-10A cells lectin did not show any adverse effect even at higher concentration. Cell cycle analysis also showed a significant cell cycle arrest on selected cells after lectin treatment. Western blotting suggested that lectin up regulates the apoptotic protein expression in MCF-7 cells while it down regulates the level of Bcl-2 expression.

    Abstract Introduction: The burden of chronic kidney disease (CKD) is rising globally including in Singapore. Primary care is the first point of contact for most patients with early stages of CKD. However, several barriers to optimal CKD management exist. Knowing healthcare professionals' (HCPs) perspectives is important to understand how best to strengthen CKD services in the primary care setting. Integrating a theory-based framework, we explored HCPs' perspectives on the facilitators of and barriers to CKD management in primary care clinics in Singapore.
    Methods: In-depth interviews were conducted on a purposive sample of 20 HCPs including 13 physicians, 2 nurses and 1 pharmacist from three public primary care polyclinics, and 4 nephrologists from one referral hospital. Interviews were audio recorded, transcribed verbatim and thematically analyzed underpinned by the Theoretical Domains Framework (TDF) version 2.
    Results: Numerous facilitators of and barriers to CKD management identified. HCPs perceived insufficient attention is given to CKD in primary care and highlighted several barriers including knowledge and practice gaps, ineffective CKD diagnosis disclosure, limitations in decision-making for nephrology referrals, consultation time, suboptimal care coordination, and lack of CKD awareness and self-management skills among patients. Nevertheless, intensive CKD training of primary care physicians, structured CKD-care pathways, multidisciplinary team-based care, and prioritizing nephrology referrals with risk-based assessment were key facilitators. Participants underscored the importance of improving awareness and self-management skills among patients. Primary care providers expressed willingness to manage early-stage CKD as a collaborative care model with nephrologists. Our findings provide valuable insights to design targeted interventions to enhance CKD management in primary care in Singapore that may be relevant to other countries.
    Conclusions: The are several roadblocks to improving CKD management in primary care settings warranting urgent attention. Foremost, CKD deserves greater priority from HCPs and health planners. Multipronged approaches should urgently address gaps in care coordination, patient-physician communication, and knowledge. Strategies could focus on intensive CKD-oriented training for primary care physicians and building novel team-based care models integrating structured CKD management, risk-based nephrology referrals coupled with education and motivational counseling for patients. Such concerted efforts are likely to improve outcomes of patients with CKD and reduce the ESKD burden.
