Poor rooting performance of Chinese pepper (Zanthoxylum beecheyanum K. Koch) shrub is a restriction for its commercial production. This investigation was carried out to assess the effectiveness of the exogenous application of indole-3-butyric acid (IBA) on adventitious root (AR) formation and some morpho-physiological, biochemical, and histological alterations associated with rhizogenesis events.

Lead (Pb) is a metal that can produces irreversible damage in living organisms. Some studies had reported that Pb produces histophysiological alterations in the digestive system (mainly liver) of birds; however, the effect of this metal on small intestine has not been fully examined. Additionally, little information is available on Pb disturbances in native birds of South America.

This article relates the life, career and main scientific achievements of a pioneer in neuroendocrinology and French cell biology research, Mrs Andrée Tixier-Vidal, who passed away in December 2021. After her first works on hypophyseal-thyroid neuroendocrine axis, in birds then in mammals, Andrée Tixier-Vidal devoted herself then her group at the College of France to the histophysiological study of adenohypophysis and namely of prolactin (PRL) cells. Using in vitro models of organotypic cultures and cultures of GH3 cells, she described up to ultrastructural level the secretory process of PRL and its regulation by TRH.

Physical exercise is an important therapeutic agent for women with diabetes during gestation. However, its histophysiological consequences for the placenta remain unclear. In this study, we evaluated the expression of VEGF-A, IL1ß, TNFα, and type I collagen in the placentas of diabetic rats subjected to a swimming program.

Background: Rodents harbour a number of parasites of public health importance, thus, they threaten human health and livestock.

Aims: The present study aimed to characterize two helminthic species found in commensal rodents and record histo-physiological alterations induced by them.

Methods: A total of 300 synanthropic rodents of three species: (n=201), Bandicota bengalensis Mus musculus and necropsied in different seasons during November 2017 to October 2019 at Ludhiana, Punjab, India.
