Can Different Dietary Protein Sources Influence the Survival, Growth, and Physiology of 0Marron () Exposed to Feed Deprivation?

We investigated the effect of feed deprivation for 45 days on the growth, immunity, and health of 0marron () initially fed for 110 days on various protein sources including fishmeal (FM), poultry by-product meal (PBM), black soldier fly meal (BSFM), soybean meal (SBM), lupin meal (LM), and tuna hydrolysate. The marron were weighed and sacrificed immediately after feeding stopped (day 0) and at days 15, 30, and 45 after the feed deprivation trial commenced. Total haemolymph count, differential haemocyte count, lysozyme activity, protease activity, total bacterial count in the digestive tract, and organosomatic indices were analysed.

A chitin-binding domain-containing gene is essential for shell development in the mollusc Tritia.

Mollusc shells are diverse in shape and size. They are created by a shell epithelium which secretes a chitinous periostracum membrane at the growing edge of the shell, and then coordinates biomineral deposition on the underside of this membrane. Although mollusc shells are important for studying the evolution of morphology, the molecular basis of the shell development is poorly understood.

Pattern of Uveitis in Northern Vietnam.

Purpose: To characterize the spectrum of uveitis in patients visiting three tertiary hospitals in Hanoi, Vietnam.

Methods: This study collected prospective and multicenter data from patients diagnosed with uveitis at three tertiary hospitals in Hanoi City, Vietnam, between January 2022 and January 2024. Data on age, sex, clinical and laboratory findings, and etiology were collected.
