the study aimed to come up with a list of specific macroalgae species, which could be used to biomonitor specific metal elements in the coastal waters of east africa. water extraction, edta, aqua regia extraction and optimized bcr 3-step sequential extracts were used to mimic bioavailable metals under various environmental conditions. the results indicated that ulva lactuca could be used as a b...
INTRODUCTION Pneumatosis intestinalis is rare but may be associated with life-threatening intra-abdominal conditions such as intestinal ischemia or perforation. However, it can be difficult, particularly in the very elderly, to identify candidates for immediate surgical intervention. PRESENTATION OF CASE A 94-year-old man with abdominal distension underwent abdominal computed tomography, whic...
BACKGROUND Hepatic portal venous gas (HPVG) in adults is a rare entity. The underlying pathologic condition is usually an intestinal ischemia, but it has been reported in association with a variety of conditions. HYPOTHESIS Miscomprehension of the underlying pathologic conditions has led to some confusion in the literature concerning its etiology, diagnostic methods, and clinical consequences...
The anaerobic intestinal pathogen Giardia intestinalis does not possess enzymes for heme synthesis, and it also lacks the typical set of hemoproteins that are involved in mitochondrial respiration and cellular oxygen stress management. Nevertheless, G. intestinalis may require heme for the function of particular hemoproteins, such as cytochrome b5 (cytb5). We have analyzed the sequences of euka...
BACKGROUND Present study aimed to investigate prevalence of Giardia intestinalis and Hymenolepis nana in Afghan refugees visiting Central Health Unit (CHU), Kot Chandana (Mianwali, Northern Punjab) during two years period (February 2007 to December 2009). METHODS A total of 687 stool samples were collected from different age groups of both genders. Samples were processed under sterile conditi...
Rabbit coccidiosis, caused by infection of Eimeria spp. is one of the most severe parasitic diseases in rabbits. Eimeria intestinalis is one of the most immunogenic species in rabbit coccidia. Due to the lack of genomic information and unsuccessful in vitro cultivation, genetic manipulation of rabbit coccidia lagged behind other apicomplexan parasites. Using regulatory sequences from E. tenella...
Pneumatosis intestinalis (gas in the bowel wall) is often a benign condition, but it may mimic bowel ischemia or infarction and lead to unnecessary surgical intervention, especially when associated with pneumoperitoneum. We present a case of benign pneumatosis intestinalis with massive pneumoperitoneum and discuss various distinguishing features that may aid in its diagnosis.
We describe a 64 year old woman with a 3-year history of scleroderma who presented as an emergency with increasing painless abdominal distention. Radiological investigations revealed a pneumoperitoneum in the absence of either visceral perforation or pneumatosis cystoides intestinalis. This is only the fourth report of spontaneous benign pneumoperitoneum complicating scleroderma without pneumat...
Cystic pneumatosis intestinalis is a rare benign entity, characterized by intramural cysts located mainly in the intestinal wall. The etiology has not yet been elucidated, but generally it is associated with a systemic disease (1-4). Colonic pneumatosis represents about 30% of gastrointestinal cases (1). We present the case of a young girl with anorexia who underwent surgical treatment for cyst...
