13. Aspects of Langerhans cells and TNF-α in the cutaneous immunity of anogenital warts,
Abstract Background: Anogenital warts are the leading sexually transmitted infection in patients seeking care at specialized clinics. They may display a vast array of forms, according to the interaction of the virus with the host's immunity. Cellular immunity is the epithelium's main form of defense against the virus, involving an active participation of th

15. Growth hormone in the tumor microenvironment
ABSTRACT Tumor development is a multistep process whereby local mechanisms enable somatic mutations during preneoplastic stages. Once a tumor develops, it becomes a complex organ composed of multiple cell types. Interactions between malignant and non-transformed cells and tissues create a tumor microenvironment (TME) comprising epithelial cancer cells, cance

16. Co-transfection of hepatocyte growth factor and truncated TGF-β type II receptor inhibit scar formation
Wound scarring remains a major challenge for plastic surgeons. Transforming growth factor (TGF)-β plays a key role in the process of scar formation. Previous studies have demonstrated that truncated TGF-β type II receptor (t-TGF-βRII) is unable to continue signal transduction but is still capable of binding to TGF-β, thereby blocking the TGF-β signaling

17. QUERCETIN SUPPLEMENTATION PREVENTS CHANGES IN THE SEROTONIN AND CASPASE-3 IMMUNOREACTIVE CELLS OF THE JEJUNUM OF DIABETIC RATS
RESUMO CONTEXTO: A serotonina (5-HT) está presente nas células epiteliais enterocromafins (CE), nos mastócitos da lâmina própria e nos neurônios entéricos. A 5-HT está envolvida na regulação da motilidade, secreção, nocepção intestinal, sistema imunológico e inflamação. Objetivo: Avaliar os efeitos do diabetes e da suplementação de que

18. Immunohistochemical localization of progesterone receptors alpha (PRA) in ovary of the pseudopregnant rabbit
Abstract Progesterone plays an important role in the reproductive function and follicular development in mammals. The aim of the present study was to examine the localization of progesterone receptor alpha (PRA) in ovary of pseudopregnant rabbit by immunohistochemical methods. Samples were collected from 14 h. to 18 days of pseudopregnancy. At the first stag

19. Mini review: immunologic functions of dual oxidases in mucosal systems of vertebrates
Resumo As células epiteliais da mucosa atuam como a primeira barreira imunológica dos organismos e entram em contato direto com os patógenos. Portanto, os hospedeiros devem ter estratégias diferenciadas para combater os patógenos de forma eficiente. Trabalhos recentes revelaram que a oxidase dupla (DUOX) desempenha um papel fundamental para a imunidade

20. Morphological study of the gastrointestinal tract of the snow trout, Schizothorax esocinus (Actinopterygii: Cypriniformes)
ABSTRACT The present study aimed to investigate the macroscopic structure of the gastrointestinal tract (GIT) of Schizothorax esocinus Heckel, 1838. The surface architecture of the buccopharynx, oesophagus and the entire intestinal tract of S. esocinus has been examined under scanning electron microscope (SEM) after fixing in 2.5% glutaraldehyde buffered wit

21. Reproductive toxicity of neem seeds (Azadirachta indica) in male quail (Coturnix coturnix japonica)
RESUMO: Considerando que o neem (Azadirachta indica A. Juss.) causa efeitos deletérios na fertilidade, objetivou-se avaliar o efeito da alimentação com sementes de neem sobre a qualidade seminal, parâmetros biométricos e morfometria testicular com codornas (Coturnix coturnix japonica Linnaeus, 1758) com 90 dias de idade, como modelo experimental. Após

22. Gingival carcinoma cuniculatum mimicking a reactive/inflammatory process
RESUMO O carcinoma cuniculado (CC), uma rara variante do carcinoma espinocelular oral, apresenta células epiteliais neoplásicas bem diferenciadas que se infiltram na submucosa ou no tecido ósseo subjacente, formando a chamada "toca de coelho", preenchida por queratina. Relatamos o caso de uma paciente de 67 anos que foi encaminhada apresentando uma massa

23. Improvement of fertility parameters with Tribulus Terrestris and Anacyclus Pyrethrum treatment in male rats
ABSTRACT Objective Anacyclus Pyrethrum (AP) and Tribulus Terrestris (TT) have been reported as male infertility treatment in several studies; however, in Iranian traditional medicine these two plants are prescribed simultaneously. In this study, we aimed to determine the effects of AP and TT extracts both separately and simultaneously on the male Wistar ra

24. Fluorofenidone inhibits apoptosis of renal tubular epithelial cells in rats with renal interstitial fibrosis
This study aimed to investigate the mechanism of fluorofenidone (AKF-PD) in treating renal interstitial fibrosis in rats with unilateral urinary obstruction (UUO). Thirty-two male Sprague-Dawley rats were randomly divided into sham, UUO, UUO + enalapril, and UUO + AKF-PD groups. All rats, except sham, underwent left urethral obstruction surgery to establish
