Li-ion batteries are invaluable for portable electronics and vehicle electrification. A better knowledge of compositional variations within the electrodes during battery operation is, however, still needed to keep improving their performance. Although essential in the medical field, magnetic resonance imaging of solid paramagnetic battery materials is challenging due to the short lifetime of their signals. Here we develop the scanning image-selected in situ spectroscopy approach, using the strongest commercially available magnetic field gradient...

Perigraft seroma is a rare complication occurs after placement of any vascular graft. It is defined as the collection of a sterile, clear and acellular liquid around prosthesis. It can appear years after surgery as a soft, palpable and painless mass. We present a perigraft seroma occurred in a 75-years-patient underwent Dacron right axillo-bifemoral bypass for Leriche's syndrome. Ultrasound and computed tomography scan revealed involvement of graft left branch and bifurcation. Although several treatment options have been proposed, removal and replacement of prosthetic affected tract with another of a different material has been proved the choice with best result...

Activating mutations of the NRAS (neuroblastoma rat sarcoma viral oncogene) protein kinase, present in many cancers, induce a constitutive activation of both the RAS-RAF-MEK-ERK mitogen-activated protein kinase (MAPK) signal transduction pathway and the PI(3)K-AKT-mTOR, pathway. This in turn regulates the formation of the eIF4F eukaryotic translation initiation complex, comprising the eIF4E cap-binding protein, the eIF4G scaffolding protein and the eIF4A RNA helicase, which binds to the 7-methylguanylate cap (m(7)G) at the 5' end of messenger RNAs...

INTRODUCTION: Disorder of sexual development (DSD) is a rare condition. The surgical treatment of these patients includes investigation of the internal genitalia, evaluation of the gonads, and if necessary gonadectomy. The prevention of germ cell tumors is the most important issue in the surgical treatment of this varied and special group of patients. This study aimed to evaluate the role of laparoscopy in the surgical treatment of patients with DSD. MATERIALS AND METHODS: Over a 4-year-period, all patients presenting with DSD who underwent laparoscopic surgery at our institution were retrospectively reviewed...

BackgroundEnterohemorrhagic Escherichia coli (EHEC) are major foodborne pathogens that constitute a serious public health threat, mainly in young children. Shiga toxins (Stx) are the main virulence determinants of EHEC pathogenesis but adhesins like intimin (eae) and Long polar fimbriae (Lpf) also contribute to infection. The TNO GastroIntestinal tract Model (TIM) was used for a comparative study of EHEC O157:H7 survival and virulence under adult and child digestive conditions.MethodsSurvival kinetics in the in vitro digestive tract were determined by plating while bacterial viability was assessed by flow cytometry analysis...

The aortic bifurcation and iliac vessels are common sites of atherosclerotic occlusive disease causing the clinical expression known as "Leriche's syndrome". An aortobifemoral bypass grafting in the setting of a septic groin remains a significant challenge to vascular surgeons. We present a 65-year-old male with complete occlusion of the distal aorta and iliac arteries; he had undergone a left axillo-femoral and femoral-femoral artery bypass 2 years prior to our evaluation. Owing to a complex graft infection in the right groin and worsening lower extremity ischemia, we performed an aortobifemoral reconstruction through the right obturator membrane...

This work explores the proton/hydroxide permeability (PH+/OH-) of membranes that were made of synthetic extremophile-inspired phospholipids with systematically varied structural elements. A fluorescence-based permeability assay was optimized to determine the effects on the PH+/OH- through liposome membranes with variations in the following lipid attributes: transmembrane tethering, tether length, and the presence of isoprenoid methyl groups on one or both lipid tails. All permeability assays were performed in the presence of a low concentration of valinomycin (10 nM) to prevent buildup of a membrane potential without artificially increasing the measured PH+/OH-...

Gastric outlet obstruction in adults is usually caused by pyloric stenosis secondary to peptic ulcer disease or malignancy. However, there are few other causes such as a foreign body and external compression due to pseudocyst pancreas. We present a rare aetiology of a large collection of pus in the lesser sac in our patient causing gastric outlet obstruction. A perforated peptic ulcer was suspected in our patient who had symptoms of sudden onset pain in epigastric region which was referred to back. This was followed by pain in upper abdomen, vomiting, constipation and fever for which patient was being managed conservatively before being referred to us...

pH-Sensitive linkers designed to undergo selective hydrolysis at acidic pH compared to physiological pH can be used for the selective release of therapeutics at their site of action. In this paper, the hydrolytic cleavage of a wide variety of molecular structures that have been reported for their use in pH-sensitive delivery systems was examined. A wide variety of hydrolytic stability profiles were found among the panel of tested chemical functionalities. Even within a structural family, a slight modification of the substitution pattern has an unsuspected outcome on the hydrolysis stability...

This paper examines the effects of four different polar headgroups on small-ion membrane permeability from liposomes comprised of Archaea-inspired glycerolmonoalkyl glycerol tetraether (GMGT) lipids. We found that the membrane-leakage rate across GMGT lipid membranes varied by a factor of ≤1.6 as a function of headgroup structure. However, the leakage rates of small ions across membranes comprised of commercial bilayer-forming 1-palmitoyl-2-oleoyl-sn-glycerol (PO) lipids varied by as much as 32-fold within the same series of headgroups...

Leriche syndrome results from thrombotic occlusion of the abdominal aorta immediately above the site of its bifurcation. Impotence in leriche syndrome is caused due to proximal obstruction, commonly involving isolated common iliac, internal iliac, internal pudendal or dorsalis penis artery. The symptoms of Leriche syndrome include intermittent and bilateral claudication, pallor, coldness and fatigue in lower extremities. Data regarding psychiatric morbidity in Leriche syndrome is unavailable. We hereby report the case of Leriche syndrome, presenting to psychiatry outpatient department with depressive disorder and erectile dysfunction (ED) with focus on dilemmas faced in the diagnosis and management in psychiatry...

René Leriche (1879-1955) was a 20(th) century French surgeon generally known in medicine for the syndrome that carries his name, namely the Leriche syndrome in the aorto-iliac occlusive disease. This paper is published to mark the commemoration of 60 year since Leriche's death. Although Dr. Leriche's legacy resides in the domain of vascular medicine, his research enclosed bone pathology and surgical management of pain. Having his surgical training done under professors Mathieu Jaboulay and Antonin Poncet, his friendship and association with Alexis Carrel and William Halsted have contributed to René Leriche's development as a surgeon, researcher and thinker...

Small push-pull molecules were synthesized in high yields by connecting a N-methyl or N-phenyl substituted thieno[2,3-b]indole electron-donating block directly to a 2,2-dicyanovinyl or (1-(dicyanomethylene)-3-oxo-1-inden-2-ylidene)methyl electron-withdrawing group. The effects of the N-substitution on thieno[2,3-b]indole and the nature of the electron-accepting group on the electrochemical, optical, and charge-transport properties were investigated by cyclic voltammetry, UV-vis spectroscopy, and the space-charge-limited current method, respectively...

The endocannabinoid system is dysregulated during obesity in tissues involved in the control of food intake and energy metabolism. We examined the effect of chronic exercise on the tissue levels of endocannabinoids (eCBs) and on the expression of genes coding for cannabinoid receptor 1 (CB1) and cannabinoid receptor 2 (CB2) (Cnr1 and Cnr2, respectively) in the subcutaneous (SAT) and visceral adipose tissues and in the soleus and extensor digitorim longus (EDL) muscles, in rats fed with standard or high-fat diet...

BACKGROUND AND OBJECTIVE: When eye diseases are treated by topical administration, the success of treatment lies in the effective drug concentration in the target tissue. This is why the drug's pharmacokinetic, in the different substructures of the eye, needs to be explored more accurately during drug development. The aim of the present analysis was to describe by rabbit model, the distribution of a drug after ocular instillation in the selected eye tissues and fluids. METHODS: By a top-down population approach, we developed and validated a population pharmacokinetics (PopPK) model, using tissue concentrations (tear, naso-lacrymal duct, cornea and aqueous humor) of a new src tyrosine kinase inhibitor (FV-60165) in each anterior segment's tissue and fluid of the rabbit eye...
