    The present study documents the fish diversity of the Korappuzha and Kanayankode rivers in Kozhikode district. Collections were conducted over a period of six months, from January to June 2024, using cast nets, drift nets, and hooks and lines. A total of 21 species, belonging to 8 orders and 18 families, were recorded, with the order Perciformes exhibiting the highest diversity. Gerres filamentosus was the most abundant species in the Korappuzha River, while Etroplus suratensis dominated in the Kanayankode River. The Shannon–Wiener biodiversity index (2.26–2.86) indicated a high level of diversity in both rivers. Notably, Horabagrus brachysoma and Hyporhamphus xanthopterus, species classified as Vulnerable by the IUCN, were also recorded. This study highlights the biodiversity and conservation significance of these river ecosystems

    Seed abortion in Pongamia pinnata (Fabaceae)

    In Pongamia pinnata only one of the two ovules develops into a seed in most of the pods. Since pollen was not found to be limiting and reduced fertilization could not completely explain the observed frequency of seed abortion, it implied an effect of postfertilization factors. Aqueous extracts of developing seeds and maternal tissue (placenta) did not influence abortion in vitro, suggesting that abortion may not be mediated by a chemical. Experimental uptake of 14C sucrose in vitro indicated that both the stigmatic and the peduncular seed have similar inherent capacities of drawing resources, but the peduncular seed is deprived of resources in the presence of the stigmatic seed. This deprivation of the peduncular seed could be offset by supplying an excess of hormones leading to the subsequent formation of two seeds in a pod. The prevalence of single-seeded pods in P. pinnata seems therefore to be a result of competition between the two seeds for maternal resources. The evolutionary significance of single-seeded pods in P. pinnata is discussed with respect to possible dispersal advantage enjoyed by such pods

    The MIntAct project—IntAct as a common curation platform for 11 molecular interaction databases

    IntAct (freely available at http://www.ebi.ac.uk/intact) is an open-source, open data molecular interaction database populated by data either curated from the literature or from direct data depositions. IntAct has developed a sophisticated web-based curation tool, capable of supporting both IMEx- and MIMIx-level curation. This tool is now utilized by multiple additional curation teams, all of whom annotate data directly into the IntAct database. Members of the IntAct team supply appropriate levels of training, perform quality control on entries and take responsibility for long-term data maintenance. Recently, the MINT and IntAct databases decided to merge their separate efforts to make optimal use of limited developer resources and maximize the curation output. All data manually curated by the MINT curators have been moved into the IntAct database at EMBL-EBI and are merged with the existing IntAct dataset. Both IntAct and MINT are active contributors to the IMEx consortium (http://www.imexconsortium.org

    Cyclopia with shoulder dystocia leading to an obstetric catastrophe: a case report

    <p>Abstract</p> <p>Introduction</p> <p>Cyclopia is a rare fetal malformation characterized by a single palpebral fissure and a proboscis associated with severe brain malformations. Approximately 1.05 in 100,000 births including stillbirths are identified as cyclopean. The prevalence is about one in 11,000 to 20,000 in live births and one in 250 during embryogenesis.</p> <p>Case presentation</p> <p>A 30-year-old Indian woman of Asian origin, sixth gravida, was referred to the labor room of our hospital. There were no ultrasound examinations performed during this pregnancy as our patient had not received regular antenatal care. We found out that the head of her baby was already outside the vulva but the remaining parts of the baby were not yet delivered. Further examination was carried out and a diagnosis of shoulder dystocia with intrauterine fetal demise was made. A stillborn baby boy of 3.5 kg was delivered using McRoberts' maneuver. The baby was suspected of having features of cyclopia and this was later confirmed by autopsy and anatomic correlation. The mother had a cervical tear which extended into the lower segment of her uterus, thus leading to the rupture of her uterus. There was a massive broad ligament hematoma on the left side of her uterus. A total abdominal hysterectomy was carried out.</p> <p>Conclusion</p> <p>Prenatal diagnosis by ultrasound examination might help in detecting cyclopia and preventing complications associated with this condition. However, in developing countries where women do not receive regular antenatal care and do not undergo prenatal diagnosis, such cases will go undetected. In our case report, the occurrence of shoulder dystocia could be coincidental, as no risk factors were previously noted.</p

    Pathological study of a rare case of lipoblastomatosis with review of literature

    No full text
    Lipoblastomatosis refers to a rare benign tumour of fetal adipose tissue, commonly encountered in early childhood. It presents as a painless, slowly growing mass, usually in superfi cial soft tissues. Microscopy reveals a lobulated architecture with variable admixture of lipoblasts and mature adipocytes, along with myxoid areas showing spindle shaped cells. The behavior is benign, though recurrences can occur. We present a case of lipoblastomatosis of the right chest wall in a 20 year-old male patient, present since early childhood. The tumour measured 21x13x4 cm; the cut section was grey white to tan. Microscopy revealed mature adipose tissue in most of the areas and an occasional lipoblast. Myxoid areas with spindle cells were seen. Adjacent muscle showed infi ltration by the tumor. This case is presented for its rarity and for having had an opportunity to study the morphology of lipoblastomatosis several years after its onset in early childhood.

    Polymorphous low-grade adenocarcinoma of parotid gland: A rare occurrence

    No full text
    Polymorphous low-grade adenocarcinoma (PLGA) is a rare salivary gland malignant tumor of low aggressiveness, commonly occurring in minor salivary glands. Its occurrence in major salivary gland has been documented albeit rarely. The striking histological feature is architectural diversity combined with benign cytologic features. We report a case of PLGA arising from left parotid in a 25-year-old male patient. On light microscopy, varied patterns were seen .The cells were uniform with bland nuclei. Neural invasion was noted
