Heterotypic tissue interactions play an indispensable role in organ generation and regeneration. In contrast to the classic examples of tissue interactions prevailing in the formation of tetrapod limbs or pectoral fins that can only take place when the interactive tissues are in intimate contacts, the interactions in deer antler formation are novel in that the inducer and the responder are sepa...

PURPOSE A single-center prospective nonrandomized cohort study was performed to investigate the safety of irreversible electroporation (IRE) for tumor ablation in humans. MATERIALS AND METHODS Thirty-eight volunteers with advanced malignancy of the liver, kidney, or lung (69 separate tumors) unresponsive to alternative treatment were subjected to IRE under general anesthesia. Clinical examina...

background: garcinia kola seed is consumed indiscriminately in nigeria without recourse to its potential toxicity. therefore, this study was aimed at assessing the toxicity of the aqueous extract of g. kola seeds on selected tissues of male rats.  methods: thirty male rats (215.00 ± 18.58 g) were assigned into four groups: a, b, c and d which received 0.5 ml of distilled water, 25, 50 and 100 m...

background: boric acid (ba) is commonly used as pesticide, disinfectant and wood preservative. its ingestion can cause serious organ damages resulting in death. case report: a 19 year old man was found dead with two empty packs of ba tablets in vicinity of his body. on autopsy examination, brownish stains along with right angle of mouth and right nostril were found. stomach was damaged with hem...

introduction: organ donation is one of the surviving procedures which can increase the life expectancy of end-stage patients. inappropriate beliefs and attitude of individuals to organ donation, their poor knowledge, and the socio-economic level are one of the most important barriers for organ donation. therefore, here knowledge and attitude levels among relatives of trauma patients regarding o...

organization of various cells lining the olfactory mucosa of puntius ticto (hamilton, 1822) were described by light as well as scanning electron microscopy. the paired olfactory chambers located antero-dorsal to the eyes and communicated outside through anterior and posterior nasal openings. the oval shaped olfactory rosette lied at the bottom of chamber and composed of 18-20 lamellae arranged ...

the german cockroach, blattella germanica, is one of the most common pest species, and is acarrier of many pathogen and allergen factors in humans. thus, regarding public health, the control of thisinsect is quite important. dietary use of hormone analogues, especially juvenoids which disrupt reproductiveorgan development, is a relatively new method to control cockroaches. in this study, the ef...

Implantation, the beginning of fetal life in utero, has complex and dynamic processes including apposition and attachment of embryo to the uterine endometrial surface, invasion, placentation and decidualization. In mice, the period when uterus is available to accept the conceptus implanted called “implantation window”, is a very limited time, around day 3-5 post-coitum (p.c.). Orchestral regula...

Objective(s): In the present study, we investigated the effect of ischemic preconditioning (IPC) on c-myb immunoreactivity as well as neuronal damage/death after a subsequent lethal transient ischemia in gerbils. Materials and Methods: IPC was subjected to a 2 min sublethal ischemia and a lethal transient ischemia was given 5 min transient ischemia. The animals in all of the groups were given ...

A transient 1D mathematical model of whole-organ renal autoregulation in the rat is presented, examining the myogenic response on multiple levels of the renal vasculature. Morphological data derived from micro-CT imaging were employed to divide the vasculature via a Strahler ordering scheme. A previously published model of the myogenic response based on wall tension is expanded and adapted to f...
