First record of Pyramodon lindas (Markle and Olney, 1990) (Ophidiforms: Carapidae) from Indian Seas

Background: The present report is the first record of the Pyramodon lindas (Markle and Olney, Bull Mar Sci 47: 269-410, 1990) from India waters. A specimen of Pyramodon lindas measuring 483 mm total length was obtained from Tuticorin of Gulf of Mannar which is the largest specimen of so far recorded. Results: The Pyramodon lindas measured 483 mm in TL, 85 mm in Head length, 18.1 mm in snout length. Body elongate, compressed to round and eel like, supramaxilla absent, anal fin origin advanced. The specimen was deposited in the National Biodiversity Museum at the Central Marine Fisheries Research Institute, Kochi (GB.28.3.3.1) Detailed mophometric and meristic characters described and discussed. Conclusion: The Pyramodon lindas reported in the present study makes the total species reported from India as four in family Carapidae. The other reports were Carapus homei (Richardson, 1846), Pyramodon punctatum (Regan, 1914), Carapus margaritiferae (Rendahl, 1921) Brotula multibarbata Temmink & Schlegel, 1846 Antennarius hispidus (Bloch & Schneider, 1801)

Celebrating HICSS50: The Past, Present, and Future of HICSS

The Hawaii International Conference on System Sciences (HICSS) celebrated its 50th anniversary (HICSS-50) in January, 2017. To mark the occasion and to pay respect to the significant standing of this conference in the global IS community, the Communications of the Association for Information Systems (CAIS) organized a special section on “Celebrating HICSS50: The Past, Present, and Future of HICSS Conference”. In this editorial, we share the guest editors’ perspectives on HICSS and summarize the three papers in the special section

Marine Biodiversity Museum (A Designated National Repository) Catalogue

The Central Marine Fisheries Research Institute, Cochin was recognized as a 'Designated National Repository' by the Government of India, in December 2007 in consultation with the National Biodiversity Authority under the Biological Diversity Act, 2002. A Designated National Repository (DNR) is an Institution authorised to keep in safe custody specimens of different categories of biological material. The Museum offers a glimpse of the bioresources of the Indian seas. Currently the museum houses six holotype specimens, 878 finfish species, 136 crustaceans, 217 molluscs, 44 echinoderms, 162 corals, 12 sponges, 20 ascidians, 82 seaweeds and 8 seagrasses besides a dolphin and three Antarctic birds. The Museum is open to scientists, teachers, students and the general public. The fact that students form more than 85% of the visitors highlights the role played by the Museum in education. A catalogue of the specimens available in the Museum has been prepared as it is expected to be of immense use to those engaged in marine biodiversity studies. I sincerely thank Dr. G. Syda Rao, Director, CMFRI whose guidance and encouragement made this a reality

Characterisation of a Novel Radiological Entity in Neurofibromatosis Type 1 - Diffuse Neurofibromatous Tissue

Objectives: To describe the prevalence, demographics and characteristics of a novel radiological entity in neurofibromatosis type 1: diffuse neurofibromatous tissue (DNFT) Design: Aretrospective, descriptive review of MDT and radiology notes. Methods: Of the 1049 patients from the NF1 adult radiology MDT minutes (2009–2021), 77 patients with DNFT were identified and clinical data were collected. MRI scans from 20 DNFT cases were interpreted. Results: Although overall gender distribution of DNFT was roughly even, it was more prevalent in females (73.9%) at the sacroiliac joint—where this entity was most common (29.9%). DNFT often involves the fibrous part of the sacroiliac joint and is seen as diffuse, streaky infiltrating tissues that cause bone erosion without mass effect. The period prevalence of scoliosis and dural ectasia on corresponding spinal levels with spinal DNFT was 62.8 and 51.2%, respectively (n=43). Conclusions: This is the first reported descriptive study of DNFT in NF1 and the first to describe its MRI features in detail. The predilection for the sacroiliac joint and the possible associations with scoliosis and dural ectasia provide important insights that can form the basis for future studies whilst also suggesting the need for active surveillance of this tissue in NF1 patients

Check list of fishes of the Gulf of Mannar ecosystem, Tamil Nadu, India

Gulf of Mannar Ecosystem (GOME) covers an area spread over Rameswaram and Kanyakumari for about 19000 km2 and lies between 78°11’E and 79°15’ E longitude and 8°49’N and 9°15’N latitude. The 21 coral islands form a network of habitats for different kinds of fishes and marine organisms. Fish samples were collected during April 2005 to March 2010 from different centers viz., Vembar, Tharuvaikulam, Vellapatti, Therespuram, Tuticorin, Alangarathattu, Pazhaykayal, Punnakayal, Kayalpattinam, Veerapandiapattinam, Thiruchendur and Manappad of Gulf of Mannar ecosystem. The present check list was the first attempt to produce a systematic list of fishes found in the Gulf of Mannar ecosystem. It includes 476 genera and 1182 species in 144 families and 39 orders, of which 628 species have been recorded in the present study

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

Natural language processing for the automated detection of intra-operative elements in lumbar spine surgery

BackgroundThe aim of this study was to develop natural language processing (NLP) algorithms to conduct automated identification of incidental durotomy, wound drains, and the use of sutures or skin clips for wound closure, in free text operative notes of patients following lumbar surgery.MethodsA single-centre retrospective case series analysis was conducted between January 2015 and June 2022, analysing operative notes of patients aged >18 years who underwent a primary lumbar discectomy and/or decompression at any lumbar level. Extreme gradient-boosting NLP algorithms were developed and assessed on five performance metrics: accuracy, area under receiver-operating curve (AUC), positive predictive value (PPV), specificity, and Brier score.ResultsA total of 942 patients were used in the training set and 235 patients, in the testing set. The average age of the cohort was 53.900 ± 16.153 years, with a female predominance of 616 patients (52.3%). The models achieved an aggregate accuracy of >91%, a specificity of >91%, a PPV of >84%, an AUC of >0.933, and a Brier score loss of ≤0.082. The decision curve analysis also revealed that these NLP algorithms possessed great clinical net benefit at all possible threshold probabilities. Global and local model interpretation analyses further highlighted relevant clinically useful features (words) important in classifying the presence of each entity appropriately.ConclusionsThese NLP algorithms can help monitor surgical performance and complications in an automated fashion by identifying and classifying the presence of various intra-operative elements in lumbar spine surgery
