The sequence of development of the components of the corneal adhesion complex (hemidesmosomes, basal lamina and anchoring fibrils) was studied in rabbit and human fetal corneas using electron microscopy and histochemical localization of type VII (anchoring fibril) collagen. In the rabbit, basal lamina was present at 15 days gestation, followed by hemidesmosomes (HDs) and anchoring fibrils (AFs)...
The objective of this study was to understand the different morpho-physiological strategies of Ligustrum lucidum, an invasive species occurring in Brazilian forest fragments under heterogeneous light conditions. Ten individuals of L. lucidum were selected and evaluated for morphological of the leaves and physiological traits. For morphological parameters were evaluated: length, width, area, ang...
Casearia sylvestris Swartz (Salicaceae) has been used in traditional medicine and its leaf extracts have been exhibited important pharmacological activities. The species presents morphological, chemical and genetic variation. Two varieties are considered due external morphological differences: C. sylvestris var. sylvestris and var. lingua. There are difficulties in definition of these varieties...
The retinofugal pathway is a useful model for axon guidance because fibers from each eye project to targets on both sides of the brain. Studies using static and real time analyses in mice at E15-17 demonstrated that uncrossed axons from ventrotemporal retina diverge from crossed axons in the optic chiasm, where specialized resident cells may direct divergence. Other studies, however, suggest th...
Excessive Ca is toxic to plants thus significantly affects plant growth and species distribution in Ca-rich karst areas. To understand how plants survive high Ca soil, laboratory experiments were established to compare the physiological responses and internal Ca distribution in organ, tissue, cell, and intracellular levels under different Ca levels for Lysionotus pauciflorus and Boea hygrometri...
