The purpose of this in situ study is to quantify the inflammatory cell subsets and the area fraction (AA%) occupied by collagen fibers in human healthy and diseased (four different stages) gingival connective tissue in order to establish a ...
Ultrastructural and proliferative features of the ventral lobe of the prostate in non-obese diabetic mice (NOD) following androgen and estrogen replacement associated to insulin therapy [0.03%]

Diabetes causes harmful effects on prostatic function. Thus, the aims of this study were to characterize morphological and proliferative features of the prostate of diabetic mice after long-term glycemic control and testosterone and estroge...
Nitric oxide stimulates embryonic somatotroph differentiation and growth hormone mRNA and protein expression through a cyclic guanosine monophosphate-independent mechanism [0.03%]

In the pituitary gland, NO is locally synthesized by gonadotroph and folliculo-stellate cells. Many reports have shown that NO can modulate the growth hormone (GH) secretion. However, its role on mice embryo GH regulation remains unclear. I...
Ultrastructure of oogenesis of two oviparous demosponges: Axinella damicornis and Raspaciona aculeata (Porifera) [0.03%]

We investigated the cytology of the oogenic cycle in two oviparous demosponges, Axinella damicornis and Raspaciona aculeata, during 2 consecutive years both by light and electron microscopy. Oocytes of both species were similar in their bas...

Recent studies have implicated the peripheral actions of ghrelin in reproductive tissues. Expression of the functional ghrelin receptor, GHS-R1a, has been shown in Sertoli and Leydig cells as well as seminiferous tubules. Therefore, we inve...
Sperm structure and ultrastructure of the Melittobia hawaiiensis, Perkins and M. australica, Girault (chalcidoidea: eulophidae) [0.03%]

Spermatozoa morphology has, for some years, been used to help answer some phylogenetic questions for Hymenoptera. This is the second study describing spermatozoa morphology of an Eulophidae species in which important characteristics were ob...
A new paradigm in the periodontal disease progression: gingival connective tissue remodeling with simultaneous collagen degradation and fibers thickening [0.03%]
牙周病进展的新范式：同时存在胶原降解和纤维增厚的牙龈结缔组织重塑

Bacterial dental plaque is considered to be the main cause of periodontal diseases, but progression of the disease is also related to the host inflammatory response. The earliest affected tissue is the gingiva, but the specific mechanisms i...
Comparison of the spermatozoan morphology of Isognomon bicolor and Isognomon alatus (Mollusca, Bivalvia, Isognomonidae) [0.03%]
两种角贝属双壳纲贝类的精子形态比较研究(Isognomon bicolor 和 I. alatus)
