Insulin delivered to the level of the cribriform plate (intranasal insulin) is being investigated for its ability to enhance memory in people with Alzheimer's disease (AD). Recent work has shown intranasal insulin can be detected in young CD-1 mice within 5 min and is still present 60 min after injection. The current study determined whether intranasal insulin transport and the subsequent brain distribution of insulin varies in young, healthy mice (CD-1) compared to those with an AD-like phenotype (aged SAMP8) or those pre-disposed to develop such a phenotype (young SAMP8)...

Mycobacterium tuberculosis produces a large number of structurally diverse lipids that have been implicated in the pathogenicity, persistence and antibiotic resistance of this organism. Most building blocks involved in the biosynthesis of all these lipids are generated by acyl-CoA carboxylases (ACCase) whose subunit composition and physiological roles have not yet been clearly established. A rather controversial data in the literature refers to the exact protein composition and substrate specificity of the enzyme complex that produces the long-chain α-carboxy-acyl-CoAs; one of the substrates involved in the last step of condensation mediated by the polyketide synthase Pks13 to synthesize mature mycolic acids...

Bronchoalveolar lavage [BAL] is an important procedure in the diagnosis of a variety of lung diseases. While it has enormous value in the diagnostics of inflammatory parenchymal diseases, its significance in lung cancer is unclear. Keeping in mind that immune therapy (e. g. application of checkpoint inhibitors) is gaining importance in the management of lung carcinoma, it is important to know if there are typical cellular patterns in BAL of lung cancer patients. Methods In a retrospective proof of principle-study, we analyzed 38 patients who underwent BAL at the initial diagnosis of lung cancer...

The largely self-managed nature of type 2 diabetes mellitus (T2DM) underscores the importance of a collaborative decision-making process between patient and provider that best aligns the medication characteristics with the needs, interests, and abilities of the patient and with the treatment goals. The treatment regimen should be kept as simple as possible. This article applies these general principles to the use of sodium glucose cotransporter-2 inhibitor (SGLT-2) therapy, based on evidence from published studies and the clinical experience of the author...

BACKGROUND: Angioedema (AE) is a potentially life-threatening condition with hereditary (HAE), acquired (AAE), or iatrogenic causes. A careful workup allows for the identification of the etiology of attacks and the appropriate management. In this cohort study, based on a clinical practice setting, we aimed at investigating clinical and laboratory findings concerning different features of patients with recurrent AE who were referred to a single, tertiary-level center for HAE. METHODS: Clinical and laboratory data of patients fulfilling the criteria for C1-inhibitor-deficient HAE (C1-INH-HAE), C1-INH-AAE, angiotensin-converting enzyme inhibitor-related AE (ACEI-RA), and idiopathic AAE (I-AAE) were evaluated...

BACKGROUND/AIMS: Overproliferation of mesangial cells was believed to play an important role in the progress of diabetic nephropathy, one of the primary complications of diabetes. Hydrogen sulfide (H2S), a well-known and pungent gas with the distinctive smell of rotten eggs, was discovered to play a protective role in diabetic nephropathy. METHODS: MTT assay was used to examine the viability of mesangial cells. Small interfering RNA was used to knock down the expression of TLR4 while specific inhibitor LY294002 to suppress the function of PI3K...

BACKGROUND/AIMS: The thaliana phytoalexin Camalexin has been proposed for the treatment of malignancy. Camalexin counteracts tumor growth in part by stimulation of suicidal death or apoptosis of tumor cells. Similar to apoptosis of nucleated cells, erythrocytes may enter suicidal death or eryptosis, which is characterized by cell shrinkage and cell membrane scrambling with phosphatidylserine translocation to the erythrocyte surface. Cellular mechanisms contributing to the complex machinery executing eryptosis include increase of cytosolic Ca2+ activity ([Ca2+]i), oxidative stress, ceramide, protein kinase C and caspases...

REVIEW
Leonidas N Duntas, Gabriela Brenta
L-thyroxine (LT4) treatment of hypothyroidism, particularly in patients with thyroid- stimulating hormone (TSH) >10mU/L, results in improved lipid profile, as LT4 stimulates low-density lipoprotein cholesterol (LDL-C) degradation and the conversion of cholesterol in bile acids by inducing LDL-receptor and 7 alpha hydroxylase expression, respectively. Statins decrease total cholesterol (TC) and LDL-C mainly by suppressing 3-hydroxy-3-methylglutaryl coenzyme A activity. Therefore, the addition of statins to LT4 treatment, following the reversal of hypothyroidism, acts synergistically and forms a powerful treatment modality in patients with this condition whose serum lipids have not achieved the target...

Insulinoma is the most common neuroendocrine tumor of the pancreas. Surgical management of insulinomas is considered to be the only curative method. However, effective glycemic control preoperatively and in unresectable insulinomas remains a significant issue. Hyperinsulinism, occurring as a result of the hormone-secreting tumor, leads to life-threatening hypoglycemia episodes which require urgent medical treatment. This article discusses current management of hypoglycemia in insulinoma patients, including: education and lifestyle modifications, pharmacotherapy (diazoxide, somatostatin analogs, mTOR inhibitor - everolimus), cytoreductive methods and continuous glucose monitoring systems...

Liver fibrosis is a common pathological condition that occurs in most conditions associated with chronic liver injury. Silymarin is a herbal product widely used for its hepatoprotective effect. Sitagliptin, a dipeptidyl peptidase-4 inhibitor (DPP4-I), is clinically used as an oral antidiabetic agent. This study was designed to investigate the effects of Sitagliptin, Silymarin, and their combination on established liver fibrosis in carbon tetrachloride (CCl4) rat model. Male albino rats received intraperitoneal injections of CCl4 three times a week for 7 weeks, as well as daily oral treatments of Sitagliptin (100mg/kg) or Silymarin (100mg/kg) or their combination during the 7 weeks of intoxication...

In the previous studies, we have found that arsenic (As) accumulation in roots of bread wheat (Triticum aestivum L.) seedlings were significantly different among different wheat cultivars, and As(V) tolerant wheat cultivars have much higher capacities of root As accumulation. However, the reason for the difference remains unclear. Four wheat cultivars with high (MM45 and FM8) or low (QF1 and HM29) levels of arsenic (As) accumulation were selected to investigate the relationship between root As(V) uptake kinetics and root As accumulation...

1,4-dioxane is an emerging contaminant that was used as a corrosion inhibitor with chlorinated solvents. Metal-activated persulfate can degrade dioxane but reaction kinetics have typically been characterized by a rapid decrease during the first 30 min followed by either a slower decrease or no further change (i.e., plateau). Our objective was to identify the factors responsible for this plateau and then determine if slow-release formulations of sodium persulfate and Fe(0) could provide a more sustainable degradation treatment...

This study aimed to verify whether a prolonged exposure to low-level mercury promotes haemodynamic disorders and studied the reversibility of this vascular damage. Rats were divided into seven groups: three control groups received saline solution (im) for 30, 60 or 90 days; two groups received HgCl2 (im, first dose, 4.6μg/kg, subsequent doses 0.07μg/kg/day) for 30 or 60 days; two groups received HgCl2 for 30 or 60 days (im, same doses) followed by a 30-day washout period. Systolic blood pressure (SBP) was measured, along with analysis of vascular response to acetylcholine (ACh) and phenylephrine (Phe) in the absence and presence of endothelium, a nitric oxide (NO) synthase inhibitor, an NADPH oxidase inhibitor, superoxide dismutase, a non-selective cyclooxygenase (COX) inhibitor and an AT1 receptor blocker...

We recently shown a novel neuro-immune competition between vasoactive intestinal peptide (VIP) and PGD2 for CRTH2 receptor, and that genistein augmented VIP and PGD2-induced eosinophil chemotaxis. However, there are neither studies on the CRTH2 gene expression in allergic rhinitis (AR) nor in the effect of tyrosine kinase inhibitors in CRTH2 gene regulation. Our Objectives were to study the gene expression modulation of CRTH2 receptor in AR patients and the effect of tyrosine kinase inhibitors (TKIs) on CRTH2 gene modulation...
