Objective: To evaluate the antimicrobial activity of polysaccharide from cuttlebone and methanolic extract from body tissue of Sepia prashadi, against ten human pathogenic bacteria and five fungi. Methods:The activity of polysaccharide and methanolic extract was investigated against Vibrio cholerae, Pseudomonas aeruginosa, Klebsiella pneumoniae, Vibrio alginolyticus, Staphylococcus aureus, Vibrio parahaemolyticus, Streptococcus sp., Streptococcus pneumoniae, Salmonella sp. and Escherichia coli, and five fungal strains such as Alternaria alternata, Candida tropicalis, Penicillium italicum, Fusarium equiseti and Candida albican using disc diffusion method and minimum inhibitory concentration (MIC) were also calculated. Results:Both polysaccharide and methanolic extract was active against gram positive than that of gram negative pathogenic bacteria but inactive against fungi. The MIC of both the extract ranging from 60 to 100 mg/mL. Conclusions: These results suggest that cephalopod polysaccharide and methanolic extract possess relatively good antibacterial activity.

Workplace accident is a big challenges for a safety professional. Workplace accidents may lead from minor to serious effects to both employees and employers alike. Accident is an unexpected and undesirable event, especially those resulting in damage, harm or unforeseen incidents. This paper also discussed all available accident theories that are commonly used in workplace as fundamental to mitigating accident. Throughout this paper, the author justified that a new or updated accident theory is needed in Malaysia. The author stated that current accident theories are based on different environments and are different in terms physical of the employee who involved in the accident. This author also stated that technology changes is also another factor which can be supporting the new or updated accident theory needed in Malaysia.

STUDY DESIGN: Retrospective cohort study. PURPOSE: To examine the clinical profile and surgical complications in patients with spinal hemangioblastomas and to evaluate the long-term outcome in them. OVERVIEW OF LITERATURE: Although considered to be histologically benign, hemangioblastomas may cause significant neurological deficits. The proportion of spinal hemangioblastomas associated with von Hippel–Lindau (VHL) disease has been estimated be 13%–59%. Preoperative neurological function correlates with postoperative neurological status. Studies have shown no difference in outcomes between sporadic and VHL-associated spinal hemangioblastomas. METHODS: This retrospective study included 14 consecutive patients treated for spinal hemangioblastomas at our institute between January 2000 and June 2013. The mean follow-up period was 5 years. Magnetic resonance imaging of the complete neuraxis was performed in all cases, and preoperative embolization was performed in two cases. RESULTS: In total, 14 patients underwent 18 surgeries, of which 15 were for spinal hemangioblastomas. Of all the patients, 86% had motor weakness and 79% presented with sensory disturbances. Preoperative McCormick functional grades were grade I in 7 (50%), grade II in 3 (21%), and grade III in 4 (29%) patients; 50% patients were diagnosed with VHL disease. All patients underwent complete resection of the tumor. Eight patients experienced deterioration in their neurological status in the immediate postoperative period; among them, five had gradual improvement. At 5-year follow-up, 11 (78.57%) patients showed good functional outcomes. CONCLUSIONS: Microsurgical excision of spinal hemangioblastomas can cause postoperative morbidity, mainly in the form of neurological deterioration. Almost half of our patients had deterioration in the McCormick grade in the immediate postoperative period. However, a complete microsurgical excision can result in good long-term functional outcomes, as most of the immediate postoperative neurological deterioration in our patients was reversible. There was no difference in the long-term functional outcomes between sporadic and VHL-associated spinal hemangioblastomas.

Oesophageal ulcerations are generally rare occurrences that are most commonly associated with gastro-oesophageal reflux disorder. Other causes include medications and infections in immunocompromised patients. Among the medications used in daily practice, doxycycline is most commonly implicated. Multiple aetiologies are generally uncommon. We report a case of mid-oesophageal ulcerations secondary to doxycycline and herpes simplex virus infection in an immunocompetent patient.

Analysis of the VP1 gene sequence of the foot and mouth disease virus (FMDV) is critical to understanding viral evolution and disease epidemiology. A standard set of primers have been used for the detection and sequence analysis of the VP1 gene of FMDV directly from suspected clinical samples with limited success. The study validated VP1-specific degenerate primer-based reverse transcription polymerase chain reaction (RT-PCR) for the qualitative detection and sequencing of serotype O FMDV lineages circulating in India. The novel degenerate primer-based RT-PCR amplifying the VP1 gene can circumvent the genetic heterogeneity observed in viruses after cell culture adaptation and facilitate precise viral gene sequence analysis from clinical samples.

A natural prodrug is a chemical compound or substance obtained from plants, microorganism, animal and marine sources. Natural products are small molecule source for Food and Drug Administration approved drugs and major sources for drug discovery. Most of the drugs for different ailment diseases undergo first pass metabolism, resulting in drug inactivation and the generation of toxic metabolites in body. Enormous numbers of prodrugs naturally present in plants, microorganism, animal and marine sources and those prodrugs undergoes chemical reaction to form non-toxic compounds. This review summarizes the list of prodrugs naturally present in the natural product.

Background and Objectives: Knowledge about myocardial Infarction (MI) symptoms is crucial because inadequate awareness ensures direct association with patient delay and adverse health events subsequently. Methods: PRISMA guidelines were followed while conducting the systematic review with PROSPERO number CRD42020219802. An electronic search was conducted comprehensively through 5 databases to find those relevant articles systematically. Prevalence was calculated for each typical symptom of MI separately and subgroup analysis according to continent, country, gender and ethnicity was done. Meta-Analysis was conducted by using statistical software R version 3.4.3. A random-effects model was used. Results: Studies from 35 different countries with 120,988,548 individuals were included in the final analysis. The prevalence of chest pain awareness was highest, while it was lowest for jaw, back, and neck pain. There was no difference in terms of awareness in males and females. Prevalence of awareness of typical MI symptoms was higher in the Caucasian white, white, and non-Hispanic white groups than in other groups. The prevalence varies from less than 5% in African countries such as Kenya, Tanzania and Asian countries such as Nepal to as high as 90% in Germany. Conclusions People are well aware of chest pain as a symptom of MI. However, there is limited knowledge regarding other typical symptoms of MI.

This study measured the clinical prevalence of peste des petits ruminants (PPR) among sheep and goats in India between 2003 and 2009 by analyzing clinical samples from suspected cases of PPR that were submitted to the Rinderpest and Allied Disease Laboratory, Division of Virology, IVRI, Mukteswar for PPR diagnosis. PPR outbreaks were confirmed by detecting PPR virus (PPRV)-specific antigen in the clinical samples. Clinical samples (blood, nasal swabs, spleen, lymph node, kidney, liver, intestine, and pooled tissue materials) were taken from a total of 592 sheep and 912 goats in different states of India and screened for the presence of PPRV antigen using a monoclonal antibody-based sandwich ELISA kit. A total of 20, 38, and 11 laboratory-confirmed PPR outbreaks occurred among sheep, goat, and combined sheep and goat populations, respectively. Our findings provide evidence of widespread PPR endemicity in India. The underlying reasons could be variations in husbandry practices in different geographical regions, agro-climatic conditions, and livestock migration. Furthermore, decrease in the number of PPR outbreaks over time might be due to the effectiveness of current live PPR vaccines and timely vaccination of target species. Vaccination against PPR has been practiced in India since 2002 to control this disease.

Aims: Present research is focused on the molecular level characterization of drug-resistant Listeria monocytogenes identified from food and water samples from Tamil Nadu, India. Methodology and results: A total of 39 food and water samples were collected from local markets and retail shops in Tamil Nadu, India and processed for the isolation and identification of bacteria. Morphology of the bacteria was analysed under a fluorescent microscope. Isolated bacteria were serotyped and screened for the presence of virulence-associated genes haemolysin (hlyA) and invasive associated protein (iapA) by Real-time polymerase chain reaction. The qPCR positive isolates were also typed by random amplified polymorphic DNA-PCR for epidemiological study. Antibiotic resistance test was done with 16 commercial antibiotics by disc diffusion method. A total of 8 (20.51%) L. monocytogenes were identified belonging to the serotype group 1/2a, 1/2b, 1/2c and 4b. PCR assays revealed the presence of hlyA (456 bp) and iapA (131 bp) genes. In RAPD, OPA-10 primer was found to generate the distinct polymorphic fragment among the isolates. All the isolates were 100% resistant to rifampicin, co-methoxazole, linezolid and oxacillin and 100% sensitive to tetracycline and chloramphenicol. Tetracycline and chloramphenicol are suggested to be a very effective antibiotic against the tested L. monocytogenes isolates. Conclusion, significance and impact of study The hlyA and iapA based quantitative PCR technique could be a rapid molecular technique for the detection of L. monocytogenes used in this study. Serotyping along with RAPD-PCR was able to discriminate between the isolates and therefore could serve as a robust and sensitive tool for typing antibiotic-resistant strains of L. monocytogenes.

Objective: Clitoria ternatea is a well-known bioactive plant used to treat several inflammatory ailments in Ayurvedic system of medicine in India. The present investigation aimed to determine the anti-inflammatory and anti-arthritic activity of ethanolic extract of Clitoria ternatea roots (EECT) in animal models. Methods: The anti-inflammatory activity of the EECT was evaluated by carrageenan and histamine-induced paw edema. Results: EECT showed a significant reduction in mean paw edema volume in both carrageenan and histamine-induced inflammation. The efficacy of EECT in rheumatoid arthritis was tested against Freund's complete adjuvant (CFA) induced arthritic model in Wistar rats. The anti-arthritic effect of EECT was determined by systematic scoring of arthritis symptoms and measuring paw edema. A considerable decrease in paw diameter was observed in the EECT (200 and 400 mg/kg) and diclofenac (10 mg/kg) treated groups after day 7. Diclofenac (10 mg/kg) and EECT (400 mg/kg) showed a significant reduction in paw diameter from day 14 compared with CFA control (P < 0.001). The anti-arthritic activity was also confirmed from the altered biochemical, haematological (Hb, RBC and WBC) and anti-oxidant parameters (SOD, MDA, CAT, and GSH). EECT (400 and 200 mg/kg) also showed a marked inhibition of joint destruction. Conclusion: This study provides a pharmacological rationale for the traditional use of C. ternatea against inflammation and rheumatoid arthritis in India.
