BACKGROUND: Chemical composition of stones is one of the important diagnostic criteria for aetiology of stone formation and treatment to prevent recurrence. This paper reports composition of stones in children at a tertiary hospital by Fourier Transformation Infrared Spectroscopy (FTIR). METHODS: Between January-June 2015, 412 urinary stones from children were analysed by FTIR. Chi-square tests were used for the comparison of categorical measurements between groups...

In common with many strongly correlated electron systems, intermediate valence compounds are believed to display a crossover from a high-temperature regime of incoherently fluctuating local moments to a low-temperature regime of coherent hybridized bands. We show that inelastic neutron scattering measurements of the dynamic magnetic susceptibility of CePd3 provides a benchmark for ab initio calculations based on dynamical mean field theory. The magnetic response is strongly momentum dependent thanks to the formation of coherent f-electron bands at low temperature, with an amplitude that is strongly enhanced by local particle-hole interactions...

ULK1 (unc51-like autophagy activating kinase 1) is a serine/threonine kinase that plays a key role in regulating macroautophagy/autophagy induction in response to amino acid starvation. Despite the recent progress in understanding ULK1 functions, the molecular mechanism by which ULK1 regulates the induction of autophagy remains elusive. In this study, we determined that ULK1 phosphorylates Ser30 of BECN1 (beclin 1) in association with ATG14 (autophagy related 14) but not with UVRAG (UV radiation resistance associated)...

BACKGROUND: Urinary bladder dysfunction in the form of acontractile/hypocontractile bladder is very common after spinal cord injury and it may lead to recurrent urinary tract infection (UTI), stones formation, and deteriorating renal function. Conventionally, these patients evacuate their bladders by life-long clean intermittent catheterization (CIC) or an indwelling catheter (IC). For these patients, another option is to use innervated skeletal muscle wrap around the bladder to augment detrusor function and voluntary evacuation of bladder...

BACKGROUND: QRS fragmentation (fQRS) is believed to reflect myocardial scar formation in patients with coronary disease. Whether early formation of fQRS in patients with ST-segment elevation myocardial infarction (STEMI) treated with percutaneous coronary intervention (PCI) is correlated with infarct size and prognosis is unknown. We assessed the prognostic value of fQRS at 60min post-PCI and its correlation with infarct size in patients with anterior STEMI managed with primary PCI. METHODS: The INFUSE-AMI trial enrolled 452 patients with anterior STEMI undergoing primary PCI...

Bladder calculi occur in female is uncommon and the evaluation of bladder stone in women with any history of previous pelvic surgery demands careful attention. Bladder erosion due to previous anti-incontinence surgery formed the nidus for stone formation, and often presented as recurrent cystitis or refractory urinary incontinence since the early postoperative period. We hereby reported a rarely delayed appearance of the symptomatic iatrogenic bladder stone occurred 10 years after previous tension-free vaginal tape procedure...

Soft tissue calcification is common in uremic patients. Wound calcification or ossification is not so prevalent except in specific conditions like inflammation and ischemia or wound tension. We present a 40-year-old transplanted patient, not only perirenal ossification but also with multiple perirenal stones. The presentation was severe pain on the site of transplantation. Pre-op CT scan revealed perirenal calcified mass. Intraoperative finding was verythick tissue accompanied with a lot of stones around the transplanted kidney...

Heterotrophic bone formation in the pelvicalyceal system acting as a nidus for stone formation is a rare phenomenon. We report a case of a 16 years old female who, during percutaneous nephrolithotomy for right renal calculi, was found to have bone attached to the renal pelvic epithelium over which stone formation had occurred.

Adoptive T cell therapies have achieved significant clinical responses, especially in hematopoietic cancers. Two types of receptor systems have been used to redirect the activity of T cells, normal heterodimeric TCRs or synthetic chimeric Ag receptors (CARs). TCRs recognize peptide-HLA complexes whereas CARs typically use an Ab-derived single-chain fragments variable that recognizes cancer-associated cell-surface Ags. Although both receptors mediate diverse effector functions, a quantitative comparison of the sensitivity and signaling capacity of TCRs and CARs has been limited due to their differences in affinities and ligands...

Background: Calcium tartrate tetrahydrate has been reported as the main mineral in urinary stones in rats that have significant tartrate in their diet, but in humans, there has been only one mention of calcium tartrate stones in the form of bladder stone, and that case was in Africa. Case Presentation: Patient is a 34-year-old Caucasian male who presented with typical symptoms of nephrolithiasis. CT abd/pelvis (renal stone protocol) revealed a 2 cm nonobstructing stone of the right renal pelvis. Patient underwent an uncomplicated right percutaneous nephrolithotomy and was noted to be stone free after surgery...

Stone formation is a known long-term complications of continent urinary reservoirs. We present a rare case of a large stone in a continent cutaneous reservoir in a 56-year-old male managed with percutaneous cystolithotomy. The patient presented with recurrent urinary tract infections and stomal incontinence. CT revealed an 8-cm stone occupying the entire lumen of his reservoir. Rather than removing this large stone through an open approach, the pouch was accessed percutaneously and lithotripsy was performed...

The urinary bladder stones are formed due to urinary retention, obstruction to the flow of urine commonly caused by enlargement of the prostate in males, urinary tract infections, and foreign body. The urinary bladder stones are usually found in males, and its presentation in females is a rare entity. Recurrence of urinary tract stones is commonly due to either repeated urinary tract infections or any metabolic condition. We present a case of a 75-year-old female patient who had a history of urinary tract infection and bladder stone formation and was operated for the 16th time recently for removal of her bladder stones...

PURPOSE: The paper focuses on the relationship of risk factors and metabolic disorders with mineralogical composition of calculi, age and gender of calcium oxalate stone formers. MATERIALS AND METHODS: Stone mineralogical composition, 24 hour biochemistry and pH-profile of urine were examined for sixty four stone formers using powder X-ray diffraction, spectrophotometric and potentiometric techniques. RESULTS: The analysis indicated that 44 % of calculi were composed of pure calcium oxalate monohydrate, whereas other 56 % contained both monohydrate and dihydrate or usually their mixtures with hydroxyl apatite...

PURPOSE: Water intake is important for preventing kidney stones. Small molecules water is a more active restructured water under magnetic field. Here, we studied the relation between small molecules water and crystal formation in the rat kidney. MATERIALS: The small molecules water was prepared by a water machine providing a 0.8-T magnetic field. Calcium oxalate crystals were induced by 0.75% EG (ethylene glycol) in male Sprague-Dawley rats by drinking small molecules water and plain water for up to 6 weeks, respectively...

Most of kidney stones are supposed to originate from Randall's plaque at the tip of the papilla or from papillary tubular plugs. Nevertheless, the frequency and the composition of crystalline plugs remain only partly described. The objective was to assess the frequency, the composition and the topography of papillary plugs in human kidneys. A total of 76 papillae from 25 kidneys removed for cancer and without stones were analysed by immunohistochemistry combined with Yasue staining, field emission-scanning electron microscopy and Fourier transformed infrared micro-spectroscopy...

Inducing thermal gradients in fluid systems with initial, well-defined density gradients results in the formation of distinct layered patterns, such as those observed in the ocean due to double-diffusive convection. In contrast, layered composite fluids are sometimes observed in confined systems of rather chaotic initial states, for example, lattes formed by pouring espresso into a glass of warm milk. Here, we report controlled experiments injecting a fluid into a miscible phase and show that, above a critical injection velocity, layering emerges over a time scale of minutes...

Jejunoileal bypass (JIB) was developed as a surgical treatment for morbid obesity in the early 1950s. However, this procedure is now known to be associated with multiple metabolic complications and has subsequently been abandoned as a viable bariatric procedure. Some of these known complications include renal stone formation, liver failure, migratory arthritis, fat-soluble deficiencies, blind-loop syndrome and severe diarrhea. Additionally, there have been animal models suggesting colon dysplasia after JIB...
