Biomaterials can be thought as the key ingredients in several implants such as those used for joints, sutures, bone plates, and medical devices such as blood tubes, artificial heart, pacemakers, etc. They function by replacing, restoring the injured or destroyed tissues or organs, and thereby help in providing better essence of life of the patients. A biomaterial which is used in making implants should contain some important desirable properties for long term usage in the body without being itself rejected. They are grouped in four different classes as Metals, Polymers, Ceramics, and Composites which can be used singly or in combination with each other to form most of the commercially available medical devices and implants. In this review we have summarized the importance of biocompatibility and the application of biocompatible materials in various fields of sciences and healthcare...

Myocardial infarction develops due to ischemia induced oxidative stress. Averrhoa Carambola fruit (ACF) is reported to possess strong antioxidant activity which may protect the heart against isoproterenol (ISO) induced myocardial infarction (MI) in rats. To evaluate this activity Averrhoa carambolafruit extract (ACFE) (200mg/kg & 400mg/kg, p.o) was administered to male wistar rats (180-250g) for 21days. At the end of this period, all the rats except rats of normal control group were administered ISO 85mg/kg intraperitonially, for 2 consecutive days to induce MI. After 48 hrs, rats were sacrificed and the level of cardiac biomarker enzymes like cardiac troponin-T (cTn-T), creatinine kinase (CK-MB) and lactatedehydrogenase1(LDH1) in serum were estimated. Also antioxidant parameters likeglutathione (GSH), malondialdehyde (MDA), catalase and superoxide dismutase (SOD) were estimated in heart tissue homogenate and histopathology of heart tissue was performed. Our results suggest that pretreatment of animals with ACFE maintain near normal levels of cardiac biomarker enzymes and antioxidant enzymes in both treatment groups (ACFE 200mg/kg, 400mg/kg) when compared to ISO treated group. Histopathological findings of...

Azetidin-2-one analogues are reported to exhibit various pharmacological activities like cholesterol absorption inhibitory activity, human tryptase, thrombin and chymase inhibitory activity, vasopressin V1a antagonist activity, antidiabetic, anti-inflammatory, antiparkinsonian and anti-HIV activity in addition to antimicrobial.1-6 In the present study, Isoniazid (INH), the established antitubercular drug was selected as the lead for the design and development of antitubercular agents with minimal toxic effects. A novel series of amino azetidinones were designed from corresponding azetidin-2-ones using various in silico methods. Docking studies were performed at Mtb enoyl acp reductase (4DRE) and the derivatives exhibited best docking scores were prepared from corresponding azetidin-2-ones by treating with various molecules containing amino groups in the presence of TEA. Azetidin-2-ones in turn were obtained from a series of INH Schiff bases by reaction with chloro acetyl chloride. Structures of the newly synthesized compounds were assigned on the basis of elemental analysis, IR, 1H NMR, 13CNMR and mass spectral studies. The newly synthesized compounds were screened for their in vitro antitubercular activity using Alamar blue assay...

Forensic science is growing rapidly in the world today. During the past ten years, medico-legal investigations highly expanded to include all areas of forensic science. The present aim of project investigated 29 samples of blood and 29 samples of saliva swabs that were collected from human volunteers. The saliva samples were collected by buccal swab but the blood samples were collected by Bode Secur Swab S.I.T. Collector. The experiments were done at four different temperatures (55°C, 37°C, 24°C and 4°C) for 28 days. The results showed that, DNA quantity that was investigated at a temperature of 4°C and 24°C in both blood and saliva samples was more or less remained the same during the whole period of the study, comparing values for day one with all other days including day 28. DNA quantification of human blood following extraction at 37°C was 46.14 ng/μl ± 0.22 at day one then starts to decrease until it reached 36.05 ng/μl ± 0.07 at day 28. In contrast, the result obtained from real-time...

Herbs & its formulations have a long history of use in the treatment of human diseases. Herbal extracts have long been regarded as a source of new and useful pharmaceuticals. According to Cragg’s investigation, approximately 62 % of commercially available drugs have natural product origins. Manjistha, or Rubia Cordifolia to give it its scientific name, is a branched climber with small, greenish white flowers that are arranged in a cluster of round, fleshy, purple fruits. Its roots have a brownish red bark from which a red dye is obtained. This plant grows well in hilly districts, and the root has medicinal values. Manjistha is considered to be one of the most valuable herbs in Ayurveda, the world’s oldest health care system that originated in India. The ancient physician and sage, Charaka has categorized the herb as varnya or that which improves the complexion, jvarahara, or that which reduces fever, and visaghna or that which detoxifies. It is also a well known rasayana – a rejuvenative. Another great sage, Sushruta has...
