We describe a new species of from the Oriental region using museum specimens collected from India and fresh material from Thailand. This species has egg morphology resembling s. lat. and , but distinctly differs from them by presence of a narrow depression at the polygon floor. We also comment on the species status of from Thailand based on egg morphology, and present a taxonomic key for identification of tropical Asian species of .

Tendon injuries present significant medical, social, and economic challenges globally. Despite advancements in tendon injury repair techniques, outcomes remain suboptimal due to inferior tissue quality and functionality. Tissue engineering offers a promising avenue for tendon regeneration, with biocompatible scaffolds playing a crucial role.

Background: Although the Notch signaling pathway is known to play an important role in ovarian follicle development in mammals, whether it is involved in oocyte maturation remains unclear. Therefore, this study was performed to elucidate the existence and role of the Notch signaling pathway during oocyte maturation in a porcine model.
Methods: Reverse transcription-polymerase chain reaction (RT-PCR) and immunocytochemical assays were used to determine the existence of Notch signaling pathway-related transcripts and proteins in porcine cumulus-oocyte complexes (COCs).

Permanent preservation of genetic resources may be indispensable for the future of humanity. This requires liquid nitrogen, as is the case for preserving animal sperm. However, this technique is expensive and poses a risk of irrecoverable sample loss on non-replenishment of liquid nitrogen in case of natural disasters.

Hox genes have been investigated in various Arthropod species, resulting in the identification of ten Hox genes, organized in a colinear arrangement within the genome. Among arthropods, crustaceans exhibit a remarkable diversity of body shapes, which are associated with a variety of egg types, embryonic development patterns, and importantly, with the modulation of Hox genes to specify the identity of body segments along the antero-posterior axis of the embryo. Although there are more than 52,000 species of crustaceans described, their genomic resources are relatively limited, making it challenging to employ several molecular tools for studying embryonic development.

Worldwide museums hold collections of eggshells representing material for descriptive studies. However, an obstacle to this is the lack of information about the original contents and weight of the entire egg (W). This study aimed to fill this gap though development of a methodological mechanism for calculating the volume of the egg interior (V), its density (D) and W.
