Introduction: Oral carcinoma is amongst the leading malignancies worldwide, with squamous cell carcinoma (SCC) as the most common type accounting for over 90% of cases. In OSCC, MMPs, (MMP9) which belongs to gelatinase group, promote tumor progression by new blood vessel formation, disturbing tissue morphology which allows tumor growth breaks the basement membrane and enables metastasis and it’s overexpression in OSCC have prognostic value. Aims and Objectives: To evaluate the expression of MMP 9 in different grades of OSCC. Material and Methods: In this prospective study, a total number of 30 blocks specimens; 10 of each well, moderately, poorly differentiated were stained with MMP9 antibodies and compared with normal oral mucosa. All the data were documented and analyzed with SPSS 20 version software. Results: Normal 10 tissues with a mean age of 31.30 years and 30 OSCC patients of 51.93 years mean age were studied. In OSCC, 18 male (60%) and 12 female (40%) were participated. Among them, 8% smoking, 15% chewing and 7% both habits were revealed. With...

Neurodegeneration accounts for diseases like Parkinson’s disease, Alzheimer’s disease, Huntington’s disease, etc. that come under neurodegenerative diseases. Parkinson’s disease is the second most common neurodegenerative disease. The main hallmarks of Parkinson’s disease are progressive loss of motor control and cognitive dysfunction. Current treatments are of reducing the symptoms, do not address the long term complications like motor and cognitive dysfunction and have serious side effects as well. Recent research has linked tyrosine kinase activity dysfunction and mitochondrial dysfunctions to the main etiologies of Parkinson’s disease of familial and sporadic origin. Since Parkinson’s disease occur due to multiple etiologies, using a combination of drugs that target different etiologies could be an ideal strategy to address neurodegeneration. In the present study, the neuroprotective efficacy of a combination of tyrosine kinase inhibitor; dasatinib and natural antioxidant resveratrol were studied. Stereotaxic infusion of rotenone was given to rats to induce Parkinson’s disease, with nine treatment groups. The neuroprotective efficacy of the drug combinations was evaluated in different treatment groups by checking, behavioral studies,...

Heterocyclic chemistry plays a very most important role in medicinal chemistry as well as in organic chemistry. Most of the drug molecule formed and possesses therapeutic activity due to the heterocyclic scaffold. A slight change in heterocyclic moiety leads to the major therapeutic change in the drug molecule. Benzothiazole can serve as a unique and versatile moiety for experimental drug design. Benzothiazole and its derivatives are the essential chemical compounds with tremendous application in research area especially in synthetic as well as in pharmaceutical chemistry because of its potent and significant pharmacological activities. As we know that benzothiazole is a combination of two rings six-membered and five-membered and it is also known that both rings are responsible for the therapeutic activity. The main objective of our study is to find what changes lead to a better corrective benzothiazole shift moiety. A well-known approach to design new drug-like molecules, which allows achieving new pharmacological profile, action, toxicity lowering, is the development of a combination of 2- aminobenzothiazoles with another heterocyclic...

Objective: The objective of this research was a synthesis of silver nanoparticles from Murraya koenigii leaves in which the particles were characterized by various techniques and to evaluate the potential antibacterial activity of synthesized nanoparticles against various human pathogens. Methods: Murraya koenigii aqueous extract of leaves were prepared by the Soxhlet method, and the bioactive compounds were analyzed by phytochemical analysis. Silver nanoparticles were synthesized which are characterized by UV-visible spectroscopic analysis, XRD, TEM, FTIR analysis and antimicrobial activity was evaluated by agar well diffusion method. Results: Phytochemical analysis of Murraya koenigii aqueous extract of leaves showed the presence of alkaloids, phenols, flavonoids, terpenoids, coumarins, and steroids. The aqueous AgNo3 solution changed from green to dark brown color after incubation. UV-visible spectroscopic analysis showed the absorbance peak at around 420 nm which indicates the synthesis of Ag NPs. TEM image showed the formation of well-dispersed silver nanoparticles in the range of 5-25 nm. X-ray diffraction (XRD)-spectrum as evidenced by the peaks at 2θ values of such peaks 38.43°, 44.40°, and...

About 5-10% of individuals with the condition of prediabetes or intermediate hyperglycemia develop diabetes annually. Prediabetes can revert to normal glycaemic state as well. Reversion to normal glucose, even when transient, is associated with a significant 56% reduced risk of future diabetes independent of previous treatment. Prediabetes is associated with many microvascular as well as macro-vascular complications. Micro-vascular complications include retinopathy, neuropathy, and micro-albuminuria while another complication like heart disease, stroke, and peripheral vascular diseases comes under the macrovascular category. These complications are directly proportional to the succession of hyperglycemia in prediabetes. Detection of the condition prediabetes / intermediate hyperglycemia is a fundamental strategy to keep people from transitioning to diabetes. Lifestyle modification is the mainstay for the management of intermediate hyperglycemia as per various research conducted on the same. The benefit of lifestyle modification with or without pharmacotherapy to prevent or delay the progression of diabetes in patients with prediabetes. When lifestyle modification is ineffective, pharmacologic treatment should be considered although there are no approved pharmacologic treatments for...
