The Effectiveness of Isometric Exercises on Pain Perception of Elderly with Osteoarthritis in Selected Old Age Homes

Introduction: India is likely to notice an endemic of osteoarthritis with about 80% of the 55 years and above population in the country suffering with wear and tear of joints. 40% of these people are likely to suffer from severe osteoarthritis, which will disable them from daily activities, say the experts quoting the World Health Organization (WHO). Objectives: The study aimed to investigate the effect of isometric exercise in elderly with osteoarthritis in a selected old age home in Delhi. Methods: A randomized control trial was conducted on 50 elderly (25 elderly in experimental group and 25 elderly in control group) aged 60 to 90 years. Nonprobability purposive sampling technique was used for selection of the sample. A structured interview schedule and Numerical Pain Rating Scale, were used for data collection and the data was analyzed using descriptive and inferential statistics. Results: Results revealed that the elderly with osteoarthritis in the experimental group had reduction in pain followed by isometric exercise compared to the elderly with osteoarthritis in the control group. Conclusion: Results confirmed that isometric exercise is an effective method of pain relief for elderly with osteoarthritis

Role of social media during Kerala floods 2018

For almost 19 years social media has been used in crisis management. During the time of natural disasters like flood, earthquake or cyclone, when all the other modes of communications are found incapable, these social media platforms such as Facebook, Twitter, Instagram, YouTube etc. are found to be the most efficient and beneficial. The present study discusses the role of social media during the Kerala Flood 2018. Results show that During the flood; Whatsapp, Facebook and Instagram are found to be used by majority of the respondents. Most of the respondents spend more than 3 hours on Whatsapp followed by Instagram and Facebook during the flood. For the information regarding the location status of friends and family, majority of respondents used Facebook followed by Whatsapp and Instagram. During the flood, majority of the respondents used the hashtag #Keralafloods, followed by #Keralafloodrelief, #cmdrf and #Keralaflood

Recent gorgonid resources of Gulf of Mannar and Palk Bay, India

The colourful seafans have been objects of attraction to man and because of aesthetic reasons theseanimals have been collected all over the world. The discovery of prostaglandins in gorgonids and theiruse in drug manufacturing industry have led to the detailed study on this resource in Gulf of Mannar by CMFRI during 1980-'87. Subsequently, several samples collected during FORV Sagar Sampada cruises were also studied

Effect of dietary tryptophan supplementation on growth, body composition and digestive enzymes activity of juvenile silver pompano Trachinotus blochii (Lacepede, 1801)

A 60-day feeding trial was conducted to study the effect of dietary supplementation of tryptophan in juvenile silver pompano Trachinotus blochii (Lacepede, 1801) (Average initial weight=6.81±0.05 g). Five isonitrogenous and isolipidic feeds supplemented with tryptophan at different levels, 0 (TRP0), 0.5 (TRP0.5), 1.0 (TRP1.0), 1.5 (TRP1.5) and 2.0 (TRP2.0) g 100 g-1 of diets were formulated. The weight gain%, specific growth rate, hepato-somatic index, digestives enzymes of stomach and intestine except protease activity in stomach, red blood cells, white blood cells, crude protein, fat and ash content of the fish were significantly influenced (p<0.05) by tryptophan supplementation. The viscero-somatic index, intraperitoneal fat ratio, muscle ratio, protease activity in the stomach and acid insoluble ash were unaffected by the treatment. Best observations in terms of growth, body composition and digestive enzyme activity among the treatments were obtained in the fish group fed with tryptophan at a level of 0.5 g 100 g-1 feed. From the current observations it can be concluded that supplementation of tryptophan at the rate of 0.5 g 100 g-1 diet can positively influence the growth of T. blochii

Culture of the soft coral, Lobophytum pauciflorum (Family: Alcyoniidae) under captive conditions at Kochi, India

A spinner dolphin, Stenella longirostris , locally called ‘handi meenu’ was noticed in dead condition floating near the marine cage farm of CMFRI, Karwar, approximately 600 m away, from sea shore of Aligadda village in the evening hours on 31st August 2012. The specimen was an adult female of 175 cm total length and 55 kg weight. The animal had a small injury near its left eye probably as a result of getting entangled in fishing nets or got injured in purse-seine operation which resulted in its death

Zooplankton abundance in Amini and Kadmat islands of Lakshadweep

Studies on zooplankters collected from the lagoons of Amini and Kadmat islands of Lakshadweep Archipelago were carried out based on a survey conducted during January - February, 2014. The displacement volume ofzooplankton in Amini and Kadmat were 58.35 and 15ml per 100 m3 respectively. The density was also higher in Amini than in Kadmat which is estimated as 64480 and 47726 numbers per 100 m3 respectively. A total of twentyone groups of zooplankters viz., copepods,ostracods, chaetognaths, Lucifer sp., medusae, doliolids,mysids, tintinnids, euphausiids, appendicularians,siphonophores, cladocera, amphipods, isopods,polychaete larvae, prawn larvae, crab larvae, squilla larvae, molluscan larvae, fish eggs and fish larvae were recorded from these two ecosystems. Groupwise studies indicated the dominance of copepods in Amini forming 40% while in Kadmat, the maximum was contributed by crab larvae (50%). The dominance of crab larvae in Kadmat was due to a swarm of zoea stage of crab at station 2 in the western side of the island.Among the copepods, calanoid copepods contributed the maximum with 71% in Amini and 81% in Kadmat.Followed by the dominance of copepods in Amini,ostracods (33%) and crab larvae (14%) formed major components. In Kadmat, copepods formed the second dominant group which contributed 20% followed by prawn larvae (11%), ostracods (6%) and the share by other groups were less than 5%. Comparative studies on the occurrence of different groups of zooplankters in these two island ecosystems showed that copepods and ostracods were very much higher in Amini than in Kadmat while, crab larvae contributed more in Kadmat which was due to the swarming of zoea stage of crab. Both qualitative and quantitative abundance of zooplankters in these two ecosystems are presentedand discussed

Bivalve maturity scales and estimation of spawning season

Molluscan reproduction is primarily regulated by the interaction of external and endogenous variables. The principal method of assessing the reproductive cycle in bivalves is based on histology. A simplified method for assessing the maturity stages of the gonad is by visual examination of the colour of the mantle tissue, followed by inspection of the fresh gonad smears under a microscope (10X magnification). Many schemes have been used to describe the seasonal reproductive cycle in bivalves. The gametes in bivalves are produced by the germinal epithelium within a web of follicles enveloped by connective tissues. Generally, these schemes recognise: indeterminate stage (immature/inactive stage); then the active stage begins with the multiplication of germ cells; growth of germinal tubules and germinal maturation including vitellogenesis in females, which is followed by sexual maturity including spawning. Usually 35-50 specimens are randomly collected at fortnightly or monthly intervals to assess maturity stages. They are measured and weighed, and a tissue smear from Indeterminate gonad stage in Brown mussel Indeterminate gonad stage in Edible oyster the middle part of the gonad is examined in the laboratory for maturity assessment. The mantle serves not only as the site of gametogenesis but also as the primary storage site for nutrient reserves, particularly glycogen. These reserves are accumulated before spawning and are utilized in gamete formation. Gametes proliferate within the mantle and during the spawning season, they are transported through ciliated channels to paired gonoducts that release them into the mantle cavity
