Vermiform Appendix and the Potential for Missed Pathologies.

Cureus 2022 May 16;14(5):e25055. Epub 2022 May 16.

Pathology, Jawaharlal Institute of Postgraduate Medical Education & Research, Puducherry, IND.

Introduction The appendix is considered an appendage of little value and is often treated disdainfully, be it as part of evolutionary process, on a grossing table, under a microscope or while archiving specimens and slides. It is only recently, with data indicating its importance in gut immunity and as the origin of pseudomyxoma, that its space in a human body appears vindicated. Aim Our aim was to screen the histopathologic spectrum of appendix lesions observed in our hospital for rare, incidental or clinico-radiologically uncertain lesions that would help emphasize a necessary seriousness in its sampling.

Context-dependent integrated stress resistance promotes a global invasive pest.

Insect Sci 2022 Mar 15. Epub 2022 Mar 15.

Department of Biological Sciences and Biotechnology, Botswana International University of Science and Technology, Palapye, Botswana.

In nature, insects concurrently face multiple environmental stressors, a scenario likely increasing with climate change. Integrated stress resistance (ISR) thus often improves fitness and could drive invasiveness, but how physiological mechanisms influence invasion has lacked examination. Here, we investigated cross-tolerance to abiotic stress factors which may influence range limits in the South American tomato pinworm-a global invader that is an ecologically and socially damaging crop pest.
