The spatial and temporal variations of mesozooplankton in relation to environmental parameters were investigated in the Persian Gulf and the Gulf of Oman. For this purpose, the physicochemical parameters were measured using a CTD probe and mesozooplankton were sampled vertically using a closing net aboard the RV Persian Gulf Explorer during two expeditions. Results showed a relationship between mesozooplankton assemblages and water mass distributions. Four mesozooplankton cluster station groups divided the sampled stations into masses, which was also confirmed by the PERMANOVA test. Overall, ninety taxa were identified that were dominated by copepods and characterized by small cyclopoids. Based on the results the mesozooplankton communities of the Persian Gulf and the Gulf of Oman are mostly shaped by the combined effect of temperature, salinity, and dissolved oxygen that significantly influences mesozooplankton occurrence during summer and spring.

Background: Snakebite envenoming is a critical medical emergency and significant global public health issue, with India experiencing the highest annual snakebite deaths. Sea snakes in the Indian Ocean pose a severe threat to rural fishermen due to their potent neurotoxins.
Methods: From December 2020 to December 2021, we conducted surveys at 15 fishing ports in East Medinipur, West Bengal, and Balasore, Odisha, India (between 21.

Objectives: F-FDG PET/CT has been used to characterize the primary lesion and staging in head and neck cancers (HNC). However, prior studies for detecting distant metastasis and synchronous tumors are sparse, especially in Indian context. To investigate the frequency and distribution of head and neck carcinomas, distant metastases and synchronous malignancies detected in HNC in a north Indian population.

Ecosystems are substantially changing in response to ongoing climate change. For example, coral reefs have declined in coral dominance, with some reefs undergoing regime shifts to non-coral states. However, reef responses may vary through multiple heat stress events, with the rarity of long-term ecological datasets rendering such understanding uncertain.

Background: In the context of global change, coral reefs and their associated biodiversity are under threat. Several conservation strategies using population genetics have been explored to protect them. However, some components of this ecosystem are understudied, such as hydrozoans, an important class of benthic organisms worldwide.
