Regenerative medicine is expected to be a novel therapeutic system in this century [1–3]. The human body consists of 200 cell species generated from immature stem cells. In the 1990s, a treatment transplanting hematopoietic stem cells to replace all blood cells was established and successfully cured leukemia [4]. With this as amodel, stem cell transplantation therapy is being developed to resto...

Artificial nutrition is an inherent part of management in acute pancreatitis. However, there is no consensus regarding the optimal time of the commencement of feeding in these patients. Our aim was to compare the effect of enteral v. parenteral nutrition with regard to the time points when they were administered in the randomised controlled trials. The search was undertaken in the Cochrane Cent...

IN THE PAST 2 DECADES, ADVANCEments in immunosuppressive strategies and major breakthroughs in surgical and organ preservation techniques have transformed organ transplantation into a therapy for an increasing population of patients with endstage organ failure. Although preventing rejection remains the principle focus in improving overall survival statistics, pulmonary complications following t...

We evaluated the effects of steady state flow and perfusion on end-organ function in a long-term calf model. The animal received a continuous-flow total artificial heart (CFTAH) that we created from two axial-flow ventricular assist devices. Pump flow, blood pressure, and other pump parameters were monitored throughout the study, as were arterial blood gas and hematologic values, including neur...

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...

We consider natural and artificial hygromorphs, objects that respond to environmental humidity by changing their shape. Using the pine cone as an example that opens when dried and closes when wet, we quantify the geometry, mechanics and dynamics of closure and opening at the cell, tissue and organ levels, building on our prior structural knowledge. A simple scaling theory allows us to quantify ...
