Randomised prospective comparative analysis of functional outcome of osteosynthesis of intra-articular distal humerus fracture using triceps reflecting and transolecrenon approach
Background: Intra articular fractures of distal humerus is one of the demanding injuries to manage due to its complex anatomy. Open reduction internal fixation is able to achieve painless, stable and mobile joint. This study is aimed at comparing functional outcome of patients treated with triceps reflecting and olecranon osteotomy approach.Methods: A hospital based randomized comparative study of 40 patients who diagnosed with distal humerus intraarticular fracture admitted in our hospital from April 2017 to March 2019. Triceps reflecting approach (group A) was used in 20 patients and olecranon osteotomy approach (group B) in 20 patients. Elbow range of movements and Mayo elbow performance score (MEPS) was used to compare outcome.Results: The mean elbow range of motion is 95.8±13.5 degree at 1 year follow up in group A and 94.5±9.3 degree in 1 year follow up at 1 year follow up in group B. The mean MEP score at end of 1 year in group A was 93.8±2.9 and in group B was 91.5±3.2 shows excellent results but there was no statistically significant difference between MEP scores of two groups. We observed 6 patients developed extension lag less than 10 degree in group A which was clinically insignificant to patients and 7 patients developed hardware prominence in group B.Conclusions: Triceps reflecting Bryan Morrey approach is equally effective as olecranon osteotomy approach in treatment of distal humerus intra articular fracture with less complication and operative time
Perspectives in Marine Aquatic Resources and Health Management
Aquatic resources are now regarded as major contributors to provisioning
services that include health-food supply and pharmaceutical products. There are
tremendous opportunities to advantageously make use of the rich biodiversity; and the
provisioning, regulatory, cultural and supporting services of our seas to meet the
emerging demands of humankind. Since biodiversity and ecosystem functioning is
inextricably linked to human societies, we have to value the services of both,
considering the growing costs of biodiversity loss and ecosystem degradation. A
greener environment with enhanced ecosystem services will be beneficial to the
ecological and human well-being
Histology and ultrastructure of male reproductive system of the Indian Spiny lobster Panulirus homarus (Decapoda: Palinuridae)
The spiny lobster Panulirus homarus, distributed along the Southeast and Southwest coasts of India,
is an important commercial species having mariculture potential. Despite its importance, the structural and
ultrastructure features of male gonads from this species have received scarce attention. Hence this study was
aimed to describe the male reproductive tract of the species, using standard histological and electron microscopy
techniques. Gonads from 94 specimens of P. homarus ranging in carapace length 37mm-92mm from
vizhinjam (Southwest coast of India.) were obtained and processed for the study (Histology-70 numbers &
ultrastructure-24 numbers). The male reproductive system consists of paired testis and vas deferens located in
the cephalo-thoracic region. Macroscopically, the reproductive tract was observed in lobsters >35mm carapace
length. In immature testis, spermatogonia were seen which measured 6.9-13.8µm in diameter and in the mature
testis primary (5.4-5.9µm) and secondary spermatocytes (2.8-3µm) and spermatids (2.2-2.4µm) were present.
Each vas deferens consists of proximal and distal portions. The spermatophoric mass begins formation in
the proximal vas deferens. In the distal vas deferens the spermatophoric mass containing the spermatozoa are
arranged in packets towards the periphery by the gelatinous matrix produced by the typhlosole. Ultrastructurally,
the spermatogonia have lamina, nucleus and mitochondria like bodies, the primary spermatocytes have nucleus,
dense chromatin and vacuolated cytoplasm and the spermatids have mitochondria, endoplasmic reticulum and
centrioles. The endoplasmic reticulum and the nuclear envelope in the spermatids form the acrosome. The radial
arms with microtubules are formed in association with the dense endoplasmic reticulum, near the nucleus. The
sperm has a spherical structure with the nucleus, lamellar region, spikes and acrosome. This is the first comprehensive
report of the structure of the male gametes and spermatogenesis in P. homarus from Indian waters
Variation in fish catches from the continental shelf between Quilon and Gulf of Mannar and its relation to oceanographic conditions during the southwest monsoon period
The present paper is based on the fishing results of FORV Sagar Sampada during July-August, 1987 along the southwest
coast of India. The fish fauna of the Quilon Bank and Wadge Bank has a dominant nemipterid element and the Gulf
of Mannar area has a dominant population of barracudas. Nemipterids constituted 88.2 and 64.4% of the total trawl catch
from the Quilon Bank and Wadge Bank respectively
Empirical linkages between ICT, tourism, and trade towards sustainable environment: evidence from BRICS countries
There is a growing utilisation of information and communication
technologies (ICT) in the recent digital era. Trade and tourism
have also attained attention as determinants of environmental
sustainability. Therefore, this study investigates linkages between
ICT, tourism, trade, economic growth, and environmental sustainability
in BRICS economies. Advanced panel estimation entitled
cross-sectionally augmented autoregressive distributed lags (CSARDL)
was applied from 1990 to 2019. Findings suggest the
adverse effect of tourism, trade, and growth factors on environmental
sustainability, whereas ICT helps promote a sustainable
environment among the targeted economies. Likewise, the shortrun
results prove that economic growth and tourism are prone to
ecological health, while trade possesses an insignificant influence
on ecological sustainability. These results suggest the integration
of ICT in trade and tourism sectors to mitigate their negative ecological
consequences
New distributional record of the insular shelf beauty Symphysanodon typus Bleeker, 1878 (Family: Symphysanodontidae) from Indian waters
The family Symphysanodontidae comprises of
small to medium sized bony fishes commonly known
as banquelovelies, slopefishes and insular shelf
beauties. They are caught in trawls operating in
depths from 50 to 500 m, mainly on the continental
shelf and slopes
Finfish diversity in the trawl fisheries of southern Kerala
Among the maritime states of India, Kerala with
a coastline of 590 km and 39,139 sq km of continental
shelf area enjoys the distinction of being the foremost
marine producer and exporter. The potential yield of
the area up to 200 m depth has been estimated to
be about 8 lakh tonnes
Performance of the ocean state forecast system at Indian National Centre for Ocean Information Services
The reliability of the operational Ocean State Forecast system at the Indian National Centre for Ocean Information Services (INCOIS) during tropical cyclones that affect the coastline of India is described in this article. The performance of this system during cyclone Thane that severely affected the southeast coast of India during the last week of December 2011 is reported here. Spec-tral wave model is used for forecasting the wave fields generated by the tropical cyclone and vali-dation of the same is done using real-time automated observation systems. The validation results indicate that the forecasted wave parameters agree well with the measurements. The feedback from the user community indicates that the forecast was reliable and highly useful. Alerts based on this operational ocean state forecast system are thus useful for protecting the property and lives of the coastal communities along the coastline of India. INCOIS is extending this service for the benefit of the other countries along the Indian Ocean rim

Sequential development of histopathological manifestations in response to experimental infection of Vibrio alginolyticus in Asian Seabass
Asian seabass (Lates calcarifer), an important species for mariculture in
the Asia-Pacific region, has been threatened by various infectious
diseases hampering the profitability of its aquaculture. Vibriosis is the
most common disease leading to considerable mortality and economic
loss. Recent studies revealed that Vibrio alginolyticus is one of the most
common species that causes vibriosis in farmed aquatic animals,
including L. calcarifer. Despite our understanding of the aetiology, there
is little information on the subsequent histological changes following
experimental infection in fish. The present study fills this gap by
investigating the sequential histopathological alterations in Asian
seabass post intraperitoneal injection with V. alginolyticus. Significant
organ changes were seen in the spleen, kidneys, liver, and to a lesser
extent, the gills. The findings revealed an initial latency before major
tissue responses occurred, with the kidney exhibiting the earliest and
most severe changes. The spleen and liver also showed substantial
alterations, while the gills showed minor changes. Experimental V.
alginolyticus infection resulted in 90-95% mortality within 24-48 hours
post-challenge. Our findings contribute to a more thorough
understanding of histological changes in Asian seabass during V.
alginolyticus infection, highlighting the importance of disease
progression, and mitigation measures
