Resveratrol: A Double-Edged Sword in Health Benefits.

Resveratrol (3,5,4'-trihydroxy-trans-stilbene) belongs to polyphenols' stilbenoids group, possessing two phenol rings linked to each other by an ethylene bridge. This natural polyphenol has been detected in more than 70 plant species, especially in grapes' skin and seeds, and was found in discrete amounts in red wines and various human foods. It is a phytoalexin that acts against pathogens, including bacteria and fungi.

Medicinal Plants Used in the Treatment of Human Immunodeficiency Virus.

Since the beginning of the epidemic, human immunodeficiency virus (HIV) has infected around 70 million people worldwide, most of whom reside is sub-Saharan Africa. There have been very promising developments in the treatment of HIV with anti-retroviral drug cocktails. However, drug resistance to anti-HIV drugs is emerging, and many people infected with HIV have adverse reactions or do not have ready access to currently available HIV chemotherapies.

An evaluation of vitamin D levels in children with seasonal allergic rhinitis during pollen season.

Background: Serum vitamin D levels have not been studied in children with seasonal allergic rhinitis (SAR). The aim of this study was to evaluate the vitamin D levels of children with SAR and to compare them to levels in healthy children during pollen season.

Methods: This study was conducted in 100 children with SAR and 100 healthy controls.

Students' unchanging smoking habits in urban and rural areas in the last 15 years.

Background: Smoking is the main preventable public health problem particularly for youth worldwide. The aim of the present study was to determine the prevalence of smoking habits among students at secondary and high schools, and to compare the findings with those of a study conducted 15 years ago in the same area.

Methods: In this cross-sectional study 6212 students (51.

Hemophagocytic bone marrow aplasia with plasma cells in a RAG2-deficient SCID case after a nonconditioned transplantation from a fully matched sibling.

We report a RAG2-deficient patient with severe combined immunodeficiency and hemophagocytic bone marrow aplasia with plasma cells after a nonconditioned transplantation from a fully matched sibling. After engraftment, disseminated BCGosis appeared because of graft versus host disease prophylaxis. On the 55th day, eosinophilia, neutropenia, and thrombocytopenia developed.

Impact of laryngopharyngeal and gastroesophageal reflux on asthma control in children.

Objective: A prospective study was carried out to determine the sensitivity and specificity of reflux symptoms and laryngeal findings to diagnose laryngopharyngeal reflux (LPR) and gastro-esophageal reflux (GER) in children with asthma by comparing the results of double probe pH monitorization and to determine the difference between controlled and uncontrolled asthma in terms of GER and LPR coexistence.

Methods: A total of 50 patients (23 girls, mean age 10.8±0.

Sodium nitroprusside and toxic epidermal necrolysis.

Sodium nitroprusside (SNP) is one of the most widely used parenteral antihypertensive agents in severe hypertension management. Toxic epidermal necrolysis (TEN) is a rare, mostly drug-induced, severe muco-cutoneous reaction with various complications and high mortality. A fifteen years old girl who is on hemodialysis for chronic renal insufficiency and was hospitalized for emergency management of hypertension, developed a diffuse maculopapular rash within minutes after SNP infusion.

Foreign body aspiration in childhood: evaluation of diagnostic parameters.

Background: Foreign body aspiration (FBA) is one of the most important preventable causes of childhood mortality and morbidity.

Objective: The aim of this study was to define the clinical and radiological features of FBA and investigate the diagnostic value of various parameters used to diagnose FBA.

Methods: The medical records of 147 children who were admitted to the hospital with a diagnosis of suspected FBA were examined.

Congenital goitrous hypothyroidism, deafness and iodide organification defect in four siblings: Pendred or pseudo-Pendred syndrome?

Pendred syndrome (PDS) is an autosomal recessive disorder characterized by congenital deafness, goiter and iodide organification defect. Presence of inner ear malformations is essential for the clinical diagnosis. Most individuals with PDS are clinically and biochemically euthyroid.

A comparative study of electrocoagulation and coagulation of aqueous suspensions of kaolinite powders.

Removal of kaolinite particles from their synthetically prepared suspensions was studied by electrocoagulation and coagulation to investigate the effect of such operating parameters as initial pH, coagulant dosage, applied voltage, current density, and time. Coagulation was more effective in a wider pH range (pH 5-8) than electrocoagulation which yielded optimum effectiveness in a relatively narrower pH range around 9, where, in both methods, these pH values corresponded to near-zero zeta potentials of kaolinite particles. The mechanism for both coagulation methods was aggregation through charge neutralization and/or enmeshment in aluminum hydroxide precipitates.

A parametric comparative study of electrocoagulation and coagulation using ultrafine quartz suspensions.

This paper attempts to compare electrocoagulation using aluminum anodes and stainless steel cathodes with conventional coagulation by aluminum sulfate dosing on aqueous suspensions of ultrafine quartz. Several key parameters affecting the efficiency of electrocoagulation and coagulation were investigated with laboratory scale experiments in search of optimal parameter values. Optimal values of the parameters were determined on the basis of the efficiency of turbidity removal from ultrafine quartz suspensions.

Newly identified c-KIT receptor tyrosine kinase ITD in childhood AML induces ligand-independent growth and is responsive to a synergistic effect of imatinib and rapamycin.

Activating mutations of c-KIT lead to ligand-independent growth. Internal tandem duplications (ITDs) of exon 11, which encodes the juxtamembrane domain (JMD), are constitutively activating mutations found in 7% of gastrointestinal stromal tumors (GISTs) but have not been described in childhood acute myeloid leukemia (AML). DNA and cDNA from 60 children with AML were screened by polymerase chain reaction (PCR) for mutations of the JMD.

Formation of caspase-3 complexes and fragmentation of caspase-12 during anisomycin-induced apoptosis in AKR-2B cells without aggregation of Apaf-1.

Treatment of AKR-2B fibroblasts with anisomycin (10 microM) led to a rapid disintegration of the cells (t1/2 = 5 h) which was complete after 24 h. Cell death was associated with typical hallmarks of apoptosis like membrane blebbing, exposure of phophatidylserine on the cell surface, nuclear condensation and specific cleavage of rRNA. However, there was no dissipation of the mitochondrial potential and no intranucleosomal fragmentation.
