This paper examines the differentiation of somites from stage-16 or -17 chick embryos cultured with or without notochord in explant cultures. Histological sections of the cultures were stained with a trichrome stain to identify the different kinds of connective tissues formed. Both anterior and posterior (epithelial) somites made muscle, cartilage and loose connective tissue in explant culture....

Cancer can significantly have ruining effects on very high of human beings, social, and economic condition. Bladder cancer has been reported as one of the most common cancers and the incidence rates of this cancer is increasing across the world. Cystectomy is a surgery to remove the urinary bladder. In the present study a part of the ileum is used instead of bladder. This study deals with mucos...

1. Fragments of skin taken from the back of the leopard frog were cultivated in a mixture of plasma and muscle extract of the same species. 2. A few hours after explanation, processes of activity are seen to arise, which finally lead to the formation of a compact epithelial rim around the fragment of skin. 3. These epithelial cells undergo gradual transformation into a spindle-shaped type of ce...

The results of the current study showed that thyroid gland in an adult domestic cat (Felis catus) is located neck area on both sides trachea at rings 1–5. consists two lobes (right and left), it surrounded by a capsule connective tissue consisting outer inner layers, layer fatty overlaps with capsule. In addition, this found histological structure composed several follicles appear different siz...

The rationale for periodontal plastic surgery was restoration of function, health and esthetics of periodontium from augmentation procedures. The subepithelial connective tissue graft is the gold standard to achieve desirable root coverage. Difficulty arises with the presence of shallow vestibule with no keratinized gingiva and a strong frenum attachment. Hereby presenting a case report to achi...

This case report is focused on the possibility of treating atrophic ridge with a reduced number of surgical procedures and a reduced healing time. A 43-year-old female patient affected by edentulism associated with horizontal resorption of the ridge was treated by means of a sagittal osteotomy and expansion of the ridge with the new modified edentulous ridge expansion (MERE) technique to obtain...

BACKGROUND Ridge preservation was developed as a therapy to prevent severe bone resorption after tooth extraction. The purpose of this study is to determine if there is any difference in the amount of new bone formation ≈3 months after extraction and ridge preservation compared to that after ≈6 months. METHODS Minimally traumatic extraction with ridge preservation using mineralized human bone...
