BACKGROUND: Amikacin has the largest spectrum among aminoglycosides, its nephrotoxic effect limits its utilization. Our purpose in this study is to review the protective effect of dexpanthenol against the nephrotoxic effect of amikacin, accompanied with histopathological and biochemical parameters. METHODS: 32 rats were randomly separated into four groups with eight in each (amikacin (1.2mg/kg/day), amikacin (1.2mg/kg/day)+dexpanthenol (500mg/kg/day), dexpanthenol (500mg/kg/day) and control)...

Glomerular mesangial cell plays a vital role in diabetic nephropathy (DN). Recent research has demonstrated that autophagy involved in the development of DN. Paeoniflorin (PF), a monoterpene glucoside, has been proved to attenuate advanced glycation end products (AGEs)-induced mesangial cell injury. However, the regulatory mechanism of PF on autophagy in mesangial cell remains unclear. The aim of this study was to explore the effect of PF on autophagy in AGEs-induced mesangial cell dysfunction. In this study, the leakage of the lactic dehydrogenase (LDH) into the extracellular medium was measured by LDH kit...

OBJECTIVE: Obesity is associated with an increased risk of developing Osteoarthritis (OA), which is postulated to be secondary to inflammation from adipose tissue (AT). There are peri-articular adipose depots in synovial joints, the association of this tissue with OA has not been extensively explored. The aim of this study was to investigate differences in local AT depots in knees with OA and changes related to class II and III obesity. METHODS: Synovium and the infrapatellar fat pad (IPFP) were collected during total knee replacement from 69 patients with end-stage OA...

Background Soluble receptor for advanced glycation end-products (sRAGE), a soluble isoform of the RAGE receptor, is elevated in lungs from patients with acute conditions such as acute respiratory distress syndrome and bronchiolitis. This study investigated whether sRAGE is present in ventilated infants. Methods Tracheal aspirates from the first week or the fifth week of life were obtained from intubated very low birth weight subjects and analyzed by Western blot. Immunohistochemistry analysis for sRAGE was performed on paraffin-embedded lung autopsy slides from 19 other infants...

Background Percutaneous endoscopic diskectomy (PED) for the lumbar spine is a relatively new technique that is becoming more common due to its relatively less invasive nature. However, one possible serious complication is an exiting nerve injury when the cannula of the endoscope is inserted into the neural canal through the intervertebral foramen. A technique to enlarge the intervertebral foramen, called foraminoplasty, was recently established to insert the cannula safely into an appropriate position in the neural canal...

Modern medicine increasingly enables survival of life-threatening diseases. On the other side, however, especially in Neurology, the questions have to be addressed how intensive the initial treatment should be and how to deal with residual states when severe functional or cognitive deficits are expected. In these cases, it is not only important to decide which medical measures are appropriate for the patient, but also whether, given the prognosis, the patient would agree with the suggested measures. This article first describes the basis for each medical action, i...

Stressful conditions can stimulate the accumulation of carotenoids in some microalgae. To obtain more knowledge of the stress response, we studied the effects of different N concentrations on unicellular content of carotenoids using Raman spectroscopic technique; cellular stoichiometric changes and the fluorescence parameters of Chlorella vulgaris were concomitantly studied. Initially, we optimized the Raman scattering conditions and demonstrated the feasibility of unicellular carotenoid analysis by Raman spectroscopic technique...

Fusarium head blight (FHB) is a destructive fungal disease of wheat (Triticum aestivum L.) that causes significant grain yield losses and end-use quality reduction associated with contamination by the mycotoxin deoxynivalenol (DON). Three winter wheat varieties ('Vulkan', 'Kraljica' and 'Golubica') were screened for FHB resistance using artificial inoculation technique under field conditions. The aim of this study was to examine a relationship between FHB resistance and the effectiveness of enzyme antioxidant system of wheat varieties under different sampling times (3, 15, 24, 48, 96, 120 and 336 hai)...

BACKGROUND: In recent years, a relationship between depression and basal dehydroepiandrosterone (DHEA) and dehydroepiandrosterone sulfate (DHEA-S) levels has frequently been suggested, but responses of these adrenal steroids to psychosocial stress have not been examined in individuals with depressive disorders. In this study, we examined salivary DHEA, DHEA-S, and cortisol/DHEA response to the Trier Social Stress Test (TSST) in individuals with depressive disorders and in healthy controls to discover whether the responses of DHEA and DHEA-S to acute psychosocial stress could be a more sensitive marker of HPA dysfunction in depressive disorders...

Microscopic, heterotopic extraovarian sex cord-stromal proliferations have only recently been reported in the literature. We describe the largest series to date, of 30 cases of microscopic, incidentally detected, heterotopic extraovarian sex cord-stromal proliferation, in women aged 25-79 yr who had undergone surgery for a range of benign and malignant gynecologic conditions. In 14 patients the foci of proliferation comprised ovarian cortical stroma, in some cases with an ovarian fibroma-like appearance. Ten cases of adenofibroma and cystadenofibroma were also identified, including 1 Brenner adenofibroma; 2 cases comprised both ovarian cortical stroma and serous cystadenofibroma; 4 cases showed sex cord proliferation resembling microscopic adult granulosa cell tumors...

BACKGROUND: It remains unknown whether continuous or scheduled intermittent bolus local anesthetic administration is preferable for transversus abdominis plane (TAP) catheters. We therefore tested the hypothesis that when using TAP catheters, providing local anesthetic in repeated bolus doses increases the cephalad-caudad cutaneous effects compared with a basal-only infusion. METHODS: Bilateral TAP catheters (posterior approach) were inserted in 24 healthy volunteers followed by ropivacaine 2 mg/mL administration for a total of 6 hours...

BACKGROUND: Sevoflurane is the most widely used inhalational anesthetic in pediatric medicine. Despite this, sevoflurane has been reported to exert potentially neurotoxic effects on the developing brain. Clinical interventions and treatments for these effects are limited. Tanshinone IIA (Tan IIA), extracted from Salvia miltiorrhiza (Danshen), has been documented to alleviate cognitive decline in traditional applications. Therefore, we hypothesized that preadministration of Tan IIA may attenuate sevoflurane-induced neurotoxicity, suggesting that Tan IIA is a new and promising drug capable of counteracting the effects of cognitive dysfunction produced by general anesthetics...
