The acute onset of purple digits is a concerning manifestation and may represent underlying, potentially life-threatening disease. Correctly identifying the etiology of purple digits is essential to proper management, and can aid in the diagnosis of systemic disease. Multiple causes of purple digits
Heavy metal ion pollution and oxygen deficiency are major environmental risks for microorganisms in aqueous habitat. The potential of purple non-sulfur photosynthetic bacteria for biomonitoring and bioremediation was assessed by investigating the photosynthetic capacity in heavy metal contaminated
Diabetic nephropathy (DN) is one of the major diabetic complications and the leading cause of end-stage renal disease. Abnormal angiogenesis results in new vessels that are often immature and play a pathological role in DN, contributing to renal fibrosis and disrupting glomerular failure. Purple
OBJECTIVE
Purple nutsedge (Cyperus rotundus L.) is a major weed of upland crops and vegetables. Recently, a flood-tolerant ecotype evolved as a serious weed in lowland rice. This study attempted to establish the putative growth and physiological features that led to this shift in
Hypoxia sensing is the generic term for pO2-sensing in humans and other higher organisms. These cellular responses to pO2 are largely controlled by enzymes that belong to the Fe(II) alpha-ketoglutarate (alphaKG) dependent dioxygenase superfamily, including the human enzyme called the factor
HIF-asparaginyl hydroxylase (FIH-1) normally couples O(2)-activation to hydroxylation of Asn(803) on the alpha-subunit of the hypoxia-inducible factor (HIFalpha), a key step in pO(2) sensing; in the absence of HIFalpha, O(2)-activation becomes uncoupled, leading to self-hydroxylation at Trp(296) and
OBJECTIVE
To observe the effects of cobalt chloride (CoCl2)-simulated hypoxia on VEGF and TGF-beta1 expression and to provide theoretical basis for deciphering the molecular mechanism of clinical distraction osteogenesis.
METHODS
The mandibular osteoblasts were obtained from newborn Wistar rats
Microbial mats that develop in shallow brackish and hyposaline ponds in the rims of two French polynesian atolls (Rangiroa and Tetiaroa) were intensively investigated during the past three years. Comparative assessment of these mats (called kopara in polynesian language) showed remarkable
Kounis syndrome represents the concurrence of acute coronary syndromes or anginal pain with allergic, hypersensitivity, and anaphylactic reactions. It can be associated with normal coronary angiogram or preexistent coronary pathology. Idiopathic anaphylaxis is defined as anaphylaxis without any
We report a case of traumatic asphyxia complicated by unwitnessed cardiac arrest in which the patient has made a good, functional recovery. Traumatic asphyxia is an uncommon clinical syndrome usually occurring after chest compression. Associated physical findings include subconjunctival hemorrhage
Subcutaneous fat necrosis of the newborn (SFN) is an uncommon disease that affects newborns who have suffered from tissue hypoxia during or following delivery. This disease appears during the first weeks of life. It consists of indurate, erythematous or purple-erythematous nodules and plaques in the
The extractable organic matter of 10 immature samples from a marl bed of one evaporitic cycle of the Vena del Gesso sediments (Gessoso-solfifera Fm., Messinian, Italy) was analyzed quantitatively for free hydrocarbons and organic sulphur compounds. Nickel boride was used as a desulphurizing agent to
The aim: Study of the influence of local oxygen deficiency on the features of the formation of keloid scars of the head and neck.Materials and methods: The research material was 17 incisional biopsy specimens of keloid scars, which were the highest age Modern microbial mats from Shark Bay present some structural similarities with ancient stromatolites; thus, the functionality of microbial communities and processes of diagenetic preservation of modern mats may provide an insight into ancient microbial assemblages and preservation. In this study,
BACKGROUND
Though to be rare, calcific uremic arteriolophathy (CUA) is an ectopic calcification entity causing pain and disabilities in patients with chronic renal insufficiency, thus increasing the morbidity and mortality.
UNASSIGNED
We report a case of four years old boy admitted with acute
