As promising alternatives to natural receptors, artificial molecularly imprinted polymers (MIPs) have received great attention in biotechnology. Nevertheless, some bottlenecks limit their further development, including low adsorption capacity, poor recognition efficiency, slow response, and insipid aqueous compatibility. Ionic liquids (ILs) show the features of tailored structures and properties, high conductivity, good solubility, and excellent stability. Because of these advantages, they have found intensive use in MIPs by remedying the latter's shortcomings...

BACKGROUND: Rathke cleft cysts (RCCs) are benign cysts arising from the pars intermedia as a result of incomplete obliteration of the Rathke pouch during development of the pituitary gland. The most common presenting symptoms are headaches, visual disturbances, and endocrinopathies. Recurrence of RCCs after surgical treatment is a well-known phenomenon after surgery with reported recurrence rates as high as 30%. Various methods have been employed to reduce the rate of recurrence. Complete cyst wall resection has been associated with increased rates of perioperative cerebrospinal fluid leak, diabetes insipidus, and carotid injury, while inconsistently demonstrating reduced recurrence rates...

Lithium has always been used as a first-choice therapy in bipolar disorders. However, its therapeutic index is restricted by placing patients at risk of potential nephrotoxic effects ranging from polyuria, to Insipid Nephrogenic Diabetes, to chronic kidney disease with a slow reduction of renal function over time. The Nephrologist has the role to diagnose chronic lithium nephropathy, monitoring its evolution and optimizing the management of risks associated with the treatment. In fact, the main objective, to be shared with the psychiatrist, is to encourage the maintenance of therapy even in the presence of nephropathy...

The aim of this study is to investigate the clinical presentation and outcomes associated with endoscopic endonasal resection of Rathke cleft cysts (RCCs). The authors retrospectively studied a series of 13 patients who were diagnosed with RCCs after endoscopic endonasal resection at the Second Xiangya Hospital between June 2016 and December 2017. All 13 patients (8 women) underwent a purely endoscopic endonasal approach (EEA) for fenestration and aspiration of RCCs with excision of the cystic wall. The patient ages varied from 25 to 67 years (mean, 45...

Hypertension is a non-transmissible chronic disease with a high prevalence, morbidity, and mortality. Different strategies for the treatment of hypertension are employed worldwide, but the control of hypertension remains a major challenge for global health. Many unsuccessful unconventional therapies have been proposed in recent years, including herbal medicines and the development of small molecules or antibodies that seek to disrupt the disease's pathogenesis. Cell-based therapies may be used as replacement or complementary treatment strategies...

Metastases of solid tumors to the pituitary gland are often asymptomatic or appereas as with diabetes insipid us. Pituitary metastases more commonly affect the posterior lobe and the infundibulum than the anterior lobe. The presentation with an acute adrenal insufficiency is a rare event. A 69-year-old men presented with vomiting, low blood pressure and hypoglycemia. Hormonal exploration confirmed a hypopituitarism. Appropriate therapy was initiated urgently. The hypothalamic-pituitary MRI showed a pituitary hypertrophy, a nodular thickening of the pituitary stalk...

OBJECTIFS: L'intoxication au monoxyde de carbone est la première cause de décès par intoxication accidentelle dans le monde, les symptômes neurologiques sont les plus fréquents mais les évènements cardiovasculaires sont rares. Nous rapportons une observation particulière. MéTHODES: Un patient de 38, sans antécédent, était admis en ranimation pour un coma sur intoxication au monoxyde de carbone. Les explorations ont mis en évidence un accident vasculaire cérébral ischémique, un syndrome coronarien aigu et un diabète insipide...

Langerhans cell histiocytosis (LCH) is characterized by the proliferation of clonal dendritic cells, while hemophagocytic lymphohistiocytosis (HLH) is an extreme inflammatory process sustained by the uncontrolled activation of macrophages. HLH can be primary or secondary, the latter arising in infectious, autoimmune or neoplastic disorders. We hereby present a young girl who developed secondary HLH while being treated for relapsed multisystem LCH under the LCH III Protocol. She fulfilled 5 of 8 HLH-2004 criteria (fever, splenomegaly, pancytopenia, ferritin level >500 μ/l and sIL-2R >2400 IU/ml) and was successfully treated by the HLH-2004 Protocol for secondary HLH...

Sarcopenia is characterized by decreases in both muscle mass and muscle function. The loss of muscle mass, which can precede decrements in muscle function, is ultimately rooted in an imbalance between the rates of muscle protein synthesis and breakdown that favors a net negative balance (i.e., synthesis < breakdown). A preponderance of evidence highlights a blunted muscle protein synthetic response to dietary protein, commonly referred to as “anabolic resistance,” as a major underlying cause of the insipid loss of muscle with age...

Gallstone ileus is a rare complication of cholelithiasis accounting for 1-4% of cases of intestinal obstruction with a predominance in the elderly population. Unfortunately, it has an insipid presentation and is associated with significant rates of morbidity and mortality. Controversy arises over the management of gallstone ileus, and while surgery remains the mainstay of treatment, the main point of contention surrounds the extent of surgery. We describe the case of an 85-year-old woman who presented with symptoms and signs of large bowel obstruction...

Environmental protection policy strives to maintain an environment favourable to human health, agriculture, and the preservation of natural heritage. Infringements upon the environment have been either by sudden deliberate action of man (construction, land reclamation, dams, etc.) or by gradual, insipid stress of chemical and physical agents (chemical substances, heat, noise, radiation, etc.). Indeliberate unwanted stress upon the environment may be measured either by observing biological effects on indicator organisms or by chemically analyzing contaminants in these organisms...

BACKGROUND AND AIMS: The watermelon, Citrullus lanatus (Cucurbitaceae), is an important fruit vegetable in the warmer regions of the world. Watermelons were illustrated in Mediterranean Antiquity, but not as frequently as some other cucurbits. Little is known concerning the watermelons of Mediterranean Europe during medieval times. With the objective of obtaining an improved understanding of watermelon history and diversity in this region, medieval drawings purportedly of watermelons were collected, examined and compared for originality, detail and accuracy...

Spongy tissue formation in 'Alphonso' mangoes (Mangifera indica L) is a major national problem leading to loss for farmers and traders. Spongy tissue is whitish sponge like tissue formed near the seed with insipid taste and off odour. Lipid peroxidation of membranes as studied by malondialdehyde formation was significantly higher in spongy tissue. Activities of antioxidative enzymes like superoxide dismutase, catalase, peroxidase and polyphenol oxidase were lower in spongy tissue. Among the antioxidative enzymes, activities of catalase and peroxidases were severely reduced leading to membrane damage in spongy tissue...

OBJECTIVE: Different approaches to the skull base have been developed through the sphenoidal sinus. Traditional boundaries of the trans-sphenoidal approach can be extended in antero-posterior and lateral plane. We review our experience with extended endoscopic endonasal approach in 127 cases. METHODS: We used the extended endoscopic endonasal approach in 127 patients with different lesions of the skull base. This study specifically focuses on: type of lesions, surgical approach, outcome and surgical complications...

We examined the role of T1r3 and Trpm5 taste signaling proteins in carbohydrate-induced overeating and obesity. T1r3, encoded by Tas1r3, is part of the T1r2+T1r3 sugar taste receptor, while Trpm5 mediates signaling for G protein-coupled receptors in taste cells. It is known that C57BL/6 wild-type (WT) mice are attracted to the tastes of both Polycose (a glucose polymer) and sucrose, whereas Tas1r3 KO mice are attracted to the taste of Polycose but not sucrose. In contrast, Trpm5 KO mice are not attracted to the taste of sucrose or Polycose...

PURPOSE: Third cranial nerve palsies are unfrequent in childhood and adolescence and are most often congenital. The association of sellar germ cell tumor and ophthalmoplegia is considered as being very rare at this age. CASE REPORT: A 11-year-old young girl was examined in emergency with a third left cranial nerve partial palsy associated with one- year duration history of hypopituitarism with insipid diabetes and growth retardation. Cerebral IRM revealed a tumor of the pituitary gland...

Wegener's granulomatosis is a granulomatous necrotizing vasculitis which predominantly affects the respiratory tract, kidney, and less frequently other organs such as the nervous system. The latter may occur in up to 54% of cases and when it does it is more frequently of the peripheral nerves. We present a 19 year old woman who commenced her disease with involvement of respiratory sinuses, lungs and kidney and who developed central insipid diabetes (CID) at onset. The CID persisted in spite of adequate response of the other organs and systems with immunosuppresor treatment...

Diabetes insipidus is an ancient disease considered under the rubric of diabetes, the Greek descriptive term for polyuria, which was unrecognized even after the sweetness of urine was reported as a characteristic of diabetes mellitus in the 17th century. It would be another century before diabetes insipidus was identified from the insipid rather than saccharine taste of urine in cases of polyuria. After its increased recognition, pathologic observations and experimental studies connected diabetes insipidus to the pituitary gland in the opening decades of the 20th century...

The aim of the study was to elucidate a relationship between the development of hypernatremia and the frequency of poor outcomes in children with severe brain injury (SBI). The retrospective study enrolled 77 children (54 boys and 23 girls) aged 1 month to 18 years, who had SBI in the period of January 2008 to September 2009, and were divided into 3 groups after treatment termination. The admission injury severity criterion was Glasgow coma scale (8 scores or less) rating. Group A comprised 51 children with SBI without hypernatremia; Group B included 14 children with SBI and hypernatremia...
