Selective integrin endocytosis is driven by interactions between the integrin α-chain and AP2.

Integrins are heterodimeric cell-surface adhesion molecules comprising one of 18 possible α-chains and one of eight possible β-chains. They control a range of cell functions in a matrix- and ligand-specific manner. Integrins can be internalized by clathrin-mediated endocytosis (CME) through β subunit-based motifs found in all integrin heterodimers.

Crude Garlic Extract Inhibits Cell Proliferation and Induces Cell Cycle Arrest and Apoptosis of Cancer Cells In Vitro.

Garlic and its lipid-based extracts have played an important medicinal role in humans for centuries that includes antimicrobial, hypoglycemic, and lipid-lowering properties. The present study was to investigate the effects of crude garlic extract (CGE) on the proliferation of human breast, prostate, hepatic, and colon cancer cell lines and mouse macrophageal cells, not previously studied. The human cancer cell lines, such as hepatic (Hep-G2), colon (Caco-2), prostate (PC-3), and breast (MCF-7), were propagated at 37°C; air/CO2 (95:5 v/v) using the ATCC-formulated RPMI-1640 Medium and 10% fetal bovine serum (FBS), while the mouse macrophage cell line (TIB-71) was propagated at 37°C; air/CO2 (95:5 v/v) using the ATCC-formulated DMEM and 10% FBS.

Effect of pioglitazone on the course of new-onset type 1 diabetes mellitus.

Objective: Type 1 diabetes mellitus (T1DM) is caused by insulin deficiency resulting from progressive destruction of β cells. The histological hallmark of the diabetic islet is mononuclear cell infiltration. Thiazolidinediones (TZDs) activate PPARg and enhance the actions of insulin.

Prospective memory and glycemic control in children with type 1 diabetes mellitus: a cross-sectional study.

Background: Prospective memory is that memory which is required to carry out intended actions and is therefore essential in carrying out the daily activities required in the self-management of type 1 diabetes mellitus (T1DM). This study aimed to identify the relationships between prospective memory and diabetic control in children with T1DM.

Method: 94 children aged 6-18 years with T1DM completed an innovative prospective memory screen, PROMS, and a series of cognitive tests.

Growth hormone deficiency and diabetes insipidus as a complication of endoscopic third ventriculostomy.

Endoscopic third ventriculostomy (ETV) has become the procedure of choice for the treatment of obstructive hydrocephalus in children and adults. Endocrinological complications of ETV in children are rare. Diabetes insipidus (DI) is the most common and accounts for only 0.

Long-term efficacy of insulin pump therapy in children with type 1 diabetes mellitus.

Objective: Insulin pumps have been well established for insulin delivery. However, questions about long-term efficacy of insulin pump therapy still remain. We evaluated the long-term efficacy of continuous insulin infusion pump therapy (CSII) in pediatric patients with type 1 diabetes mellitus (T1DM).

Consultation with the specialist: thyroid nodules.

Based on strong research evidence, thyroid nodules in children and teenagers are more likely to be malignant than in adults. Based on strong research evidence, a history of ionizing radiation to the head or neck is an independent risk factor for the development of thyroid malignancies. There is strong research evidence, including a recent meta-analysis, supporting the use of fine-needle aspiration biopsy in the evaluation of all pediatric and adolescent patients presenting with a thyroid nodule.

A nanoemulsion formulation of dacarbazine reduces tumor size in a xenograft mouse epidermoid carcinoma model compared to dacarbazine suspension.

Unlabelled: Dacarbazine (DAC) is an anticancer drug that has been used to treat various types of cancers. The aim of the current study was to test whether there is an increased efficacy of DAC as a nanoemulsion on reducing tumor size in an epidermoid carcinoma xenograft mouse model. Tumors were induced in 5-week-old nude mice by subcutaneous injection.

The effect of oral leucine on protein metabolism in adolescents with type 1 diabetes mellitus.

Lack of insulin results in a catabolic state in subjects with insulin-dependent diabetes mellitus which is reversed by insulin treatment. Amino acid supply, especially branched chain amino acids such as leucine, enhances protein synthesis in both animal and human studies. This small study was undertaken to assess the acute effect of supplemental leucine on protein metabolism in adolescents with type 1 diabetes.

Increased consumption of dietary cholesterol, lutein, and zeaxanthin as egg yolks does not decrease serum concentrations and lipoprotein distribution of other carotenoids, retinol, and tocopherols.

We have previously reported that consumption of lutein and zeaxanthin as 2 and 4 egg yolks per day for 5 weeks significantly increased serum lutein and zeaxanthin concentrations in older adults taking cholesterol-lowering statins. We hypothesized that increased consumption of eggs, lutein, and zeaxanthin may correlate with decreased absorption of other carotenoids and increased absorption of vitamins A and E, thus affecting their serum concentrations and lipoprotein distribution. Fifty-two subjects aged at least 60 years consumed 2 egg yolks per day followed by 4 egg yolks per day for 5 weeks each with a 4-week egg-free period at baseline and between the 2 interventions.

Encapsulation of cadmium selenide quantum dots using a self-assembling nanoemulsion (SANE) reduces their in vitro toxicity.

Although, nanometer-scale semi-conductor quantum dots (QDs) have attracted widespread interest in medical diagnosis and treatment, many can have intrinsic toxicities, especially those composed of CdSe, associated with their elemental composition. Using our self-assembling nanoemulsion (SANE) formulations which we have previously reported to be composed of non-toxic components, i.e.

Reversible pituitary hyperplasia at birth in a macrosomic full-term baby boy.

Pituitary hyperplasia is generally associated with end-organ failure such as primary hypothyroidism, physiological changes such as puberty and pregnancy, or neoplasms secreting releasing factors. We present a full-term infant with an enlarged pituitary height of 8 mm at age 3 days despite a normal endocrinological evaluation. Repeat imaging at 5 months of age revealed a normal-size pituitary gland.

Prime-time hypoglycemia: factitious hypoglycemia during insulin-pump therapy.

Unexplained hypoglycemia in a pediatric diabetic patient can perplex even the savviest health care providers and lead to an extensive medical workup. We present here the cases of 2 children with type 1 diabetes mellitus treated with insulin pumps who were hospitalized for episodes of hypoglycemia. Review of their insulin pumps revealed normal basal and bolus insulin delivery.

Does pituitary stalk function improve with age?

Ectopic posterior pituitary hyperintensity on MRI is a common feature associated with growth hormone deficiency. The presence of at least some residual components of the pituitary stalk is necessary for adequate anterior pituitary function. Little is known about long-term change in pituitary function or MRI findings in patients with ectopic posterior pituitary and interrupted pituitary stalk.

Cytology and flow cytometry to identify ectopic thymic tissue masquerading as a thyroid nodule in two children.

Background: Clinically unapparent thyroid nodules in children pose a significant problem in differential diagnosis and management. Ectopic thymic tissue in the thyroid gland is rare, but may masquerade as a thyroid nodule. This paper demonstrates the utility of flow cytometry as an adjunct to cytology by fine needle aspiration in diagnosing ectopic thymic tissue in the thyroid gland.

Effect of inspiration/expiration on height measurement.

Background: Growth parameters are a powerful screening tool in pediatric care. Accuracy assumes differing importance in different clinical settings. A small error is not clinically significant when height is obtained as a screening tool during annual well child visits.

Nanoemulsions of an anti-oxidant synergy formulation containing gamma tocopherol have enhanced bioavailability and anti-inflammatory properties.

The present study investigated whether MicroFluidizer Processor-based nanoemulsions of an antioxidant synergy formulation (ASF), containing delta, alpha and gamma tocopherol influenced inflammation and bioavailability in CD-1 mice. Croton oil was applied to all animals' right ear lobe to induce inflammation. Auricular thickness was measured after 2 and 6h after the various treatments.

Congenital nephrotic syndrome and persistent hypothyroidism after bilateral nephrectomy.

Congenital nephrotic syndrome is commonly associated with hypothyroidism. Thyroid hormone supplementation is recommended as standard of care. The hypothyroidism is postulated to occur secondary to chronic massive proteinuria with loss of thyroid binding globulin, thyroid hormone and iodine.

Effect of insulin with oral nutrients on whole-body protein metabolism in growing pubertal children with type 1 diabetes.

Insulin treatment of children with insulin-dependent diabetes mellitus improves whole body protein balance. Our recent study, conducted in pubertal children with type 1 diabetes with provision of both insulin and amino acids, indicated a positive effect of insulin on protein balance, primarily through decreased protein degradation. The current study was undertaken to assess the effect of insulin on protein metabolism in adolescents with type 1 diabetes during oral provision of a complete diet.

The management of central diabetes insipidus in infancy: desmopressin, low renal solute load formula, thiazide diuretics.

Infants consume most of their calories as formula. Because of this large fluid intake, infants normally produce dilute urine, not far off from that seen in individuals with diabetes insipidus (DI). Infants with DI are therefore prone to water intoxication if fixed antidiuresis is achieved using the long-acting vasopressin analog desmopressin (DDAVP), which induces a state of high urine concentration.
