REVIEW
Yuan Li, Ke-Wu Zeng, Xue-Mei Wang
Diabetes mellitus, a kind of chronic metabolic disease, has become one of major threats to human health with an increasing incidence. As a basic pathology of chronic complications related to diabetes mellitus, cerebral microangiopathy is mainly found in patients with Alzheimer's disease and lacunar infarction, and becomes one of the main reasons of death and disability in diabetic patients. The pathogenesis of cerebral microangiopathy is complicated, involving such signal pathways as metabolic abnormalities of polyol, saccharification hyperactivity, oxidative stress, abnormal transport of amyloid-β across blood-brain barrier and protein kinase C activation...

BACKGROUND: Endothelial dysfunction is a key vascular alteration in chronic kidney disease (CKD). Omega 3 (n-3) polyunsaturated fatty acids (PUFA) reduce vascular oxidative stress and inflammation. We investigated whether n-3 PUFA could reverse endothelial dysfunction in CKD by improving endothelial nitric oxide synthase (eNOS) function and oxidative stress. METHODS: 5/6 nephrectomized male Wistar rats (CKD; n = 10) and sham operated animals (SHAM; n = 10) were treated for 6 weeks with standard diet...

Hipoxia inducible factor-1 and HIF-2 are responsible for the adaptation of cell metabolism to hypoxia. Previously, a more severe capillary rarefaction was found in locomotor than in postural muscles of uremic animals. The aim of this study was to analyze the expression patterns of HIF and prolyl hydroxylases (PHDs) in functionally different skeletal muscles in uremic rats, an experimental model of chronic kidney disease (CKD). Rats were randomized to sham operation - CON, uninephrectomy - CKD1/2 or subtotal nephrectomy - CKD5/6...

Hypokalemia is a common electrolyte disorder in hospitalized patients and those with chronic diseases and is associated with renal tubular injury. Our recent expression proteomics study revealed changes in levels of several proteins in renal tubular cells during K(+) deficiency. However, functional significance and mechanisms underlying such changes remained unclear. The present study, thus, aimed to investigate functional changes of renal tubular cells induced by K(+) deficiency. MDCK cells were maintained in normal-K(+) (ANK; [K(+)] = 5...

The genetic markers in inflammatory responses during mastitis afford a reasonable way for improving milk production in the Egyptian buffalo breed. Among them is the interleukin 8 Receptor Gene (IL8RB) (CXCR2); a chemokine receptor gene augments the neutrophil migration during infection. To understand its role better during mastitis in Egyptian buffalos, twenty-five dairy animals representing the normal, sub-clinically, clinically and chronically affected buffalos were randomly selected from different districts...

The use of the chemotherapeutic drug doxorubicin (DOX) is limited by its toxicity in several organs such as testes. So, we analyzed the effect of endurance treadmill exercise training (EX) performed before sub-chronic DOX treatment on sperm count and motility, testes markers of oxidative damage and apoptosis. Tissue profiling of proteins more susceptible to oxidation was made to identify the molecular pathways regulated by oxidative modifications, as nitration and carbonylation. Twenty-four adult male rats were divided into four groups (n=6/group): sedentary saline (SED+SAL), sedentary sub-chronically injected with DOX (2mg-kg-1 per week, during 7 weeks; SED+DOX), 12 weeks trained saline (EX+SAL) and trained treated with DOX (EX+DOX)...

Despite long use of antiepileptic drugs, it remains a challenge to achieve seizure control while reducing adverse effects and preventing cognitive impairment. Several lines of evidence suggest a role of vitamin D in epilepsy. So this study aimed to investigate the effect of vitamin D on epileptogenesis, cognitive dysfunction and antiepileptic activity of lamotrigine, in a rat model of chemical kindling. Rats were kindled by pentylenetetrazole injections every other day over four weeks, together with daily oral treatment by either vehicle, vitamin D, lamotrigine or combination of vitamin D and lamotrigine...

Schizophrenia is a severe syndrome that affects about 1% of the world population. Since the mid-1950s, antipsychotics have been used to treat schizophrenia with preference for treating positive symptoms; however, their tolerance level is low, there are numerous side effects, and only some patients respond to the treatment. Antipsychotic medications that are more effective, better tolerated, and with fewer adverse effects are urgently needed. Given the accumulating evidence of the role filled by the ErbB signaling network in the biology of the dopamine, GABA, and glutamate systems, and in the etiology of schizophrenia, we hypothesized that the ErbB network is a candidate for development of a novel agent through which various symptoms of schizophrenia and other psychiatric disorders might be treated...

There is a great deal of evidence about the mental health implications of physical child abuse and environmental stressors, or hardships that people experience at the household and neighborhood level (e.g., neighborhood violence; economic hardship, substance abuse, or conflict among family members). Yet, studies often focus on either abuse or environmental stress, not both, or examine abuse and environmental stressors as a combined set of experiences. Less is known, therefore, about how child abuse and environmental stress might work as either distinct or interrelated risks to diminish mental health over time...

Red blood cell count plays a vital role in identifying the overall health of the patient. Hospitals use the hemocytometer to count the blood cells. Conventional method of placing the smear under microscope and counting the cells manually lead to erroneous results, and medical laboratory technicians are put under stress. A computer-aided system will help to attain precise results in less amount of time. This research work proposes an image-processing technique for counting the number of red blood cells. It aims to examine and process the blood smear image, in order to support the counting of red blood cells and identify the number of normal and abnormal cells in the image automatically...
