STUDY DESIGN: This is a retrospective study analysis. OBJECTIVE: The purpose of our study was to evaluate the healing process of the ilium after being used as a bone graft donor site in the treatment of adolescent idiopathic scoliosis. SUMMARY OF BACKGROUND DATA: Iliac crest bone grafts have been proven to be the most reliable means for solid fusion in spine surgery. Nevertheless, few reports in the literature describe the ability of the iliac crest to regenerate...

The synthesis of four new analogues of marine nucleoside trachycladine A was accomplished via direct regio- and stereoselective Vorbrüggen glycosylations of 2,6-dichloropurine and 2-chloropurine with a D-ribose derived chiron. Naturally occurring trachycladines (A and B) and a series of analogues were examined for their cytotoxic activity against a number of cancer cell lines (glioblastoma, lung and cervical cancer). Parent trachycladine A and two analogues (the diacetate of 2,6-dichloropurine derivative and N-cyclopropyl trachycladine A) were found to result in a significant reduction of cell viability, with the latter exhibiting a stronger effect...

BACKGROUND: Non-documented palpitations, or phantom tachycardias, are palpitations deemed to be of unknown origin after evaluation with conventional diagnostic tools, such as 12-lead electrocardiogram and Holter recordings. Our aim was to determine the diagnostic value of an electrophysiologic study (EPS) and its role in the management of patients presenting with non-documented palpitations. METHODS: We performed EPS in 78 consecutive patients with repeatable, poorly tolerated symptoms of paroxysmal, non-documented tachycardia, the absence of structural heart disease and at least one 24-h Holter recording...

ETHNOPHARMACOLOGICAL RELEVANCE: The Asteraceae (alt. Compositae) family incorporates a large number of flowering plants, which have been classified under ca. 1600 genera covering more than 23,000 species. The genus Achillea is one of the best-known genera of this family. The Achillea species are important for their uses in the chemical and pharmaceutical purposes, and traditional and folk medicines. From ethnobotanical point of view, they heve been recommended as effective tonic, sedative, diuretic and carminative remedies and extensively prescribed for the treatment of stomachache, inflammation, gastrointestinal, hemorrhoid, hay fever, and wound healing in indigenous medicines...

Representatives of the Achillea genus are widely used as foods or nutraceuticals. Considering the increasing demand for herbal dietary supplements with health promoting effects, the objective of this research was to evaluate the biological and chemical profiles of different extracts (ethyl acetate, methanol and water) obtained from three Achillea species (A. biebersteinii, A. millefolium and A. teretifolia). The antioxidant (free radical scavenging (DPPH and ABTS), reducing power (CUPRAC and FRAP), metal chelating and phosphomolybdenum), enzyme inhibitory (anti-cholinesterase, anti-tyrosinase, anti-amylase and anti-glucosidase) and antimicrobial (antibacterial and antifungal) effects were assessed to investigate their biological profiles...

Achillea wilhelmsii C. Koch contains a variety of components such as flavonoid. The previous studies showed that flavonoid has anti-cancer properties. The aim of the present study was to determine the anti-proliferative and apoptosis-inducing potential of hydroalcoholic Achillea wilhelmsii C. Koch extract (HAWE) on MCF-7 and MDA-Mb-468 human breast carcinoma cell lines. The anti-proliferative activity of HAWE was evaluated using MTT, flowcytometry by annexin V/PI double staining, and caspase-3 activity. The results of MTT showed that the ED50 of MCF-7 and MDA-Mb-468 was 25μg/ml of HAWE, 48h after treatment...

Noninvasive prenatal testing (NIPT) using whole genome and targeted sequencing has become increasingly accepted for clinical detection of Trisomy 21 and sex chromosome aneuploidies. Few studies have shown that sub-chromosomal deletions or duplications associated with genetic syndromes can also be detected in the fetus noninvasively. There are still limitations on these methodologies such as the detection of variants of unknown clinical significance, high number of false positives, and difficulties to detect small aberrations...

OBJECTIVE: The objective of this study was to establish an evidence-based clinical practice guideline for the primary management of obstetrical brachial plexus injury (OBPI). This clinical practice guideline addresses 4 existing gaps: (1) historic poor use of evidence, (2) timing of referral to multidisciplinary care, (3) Indications and timing of operative nerve repair and (4) distribution of expertise. SETTING: The guideline is intended for all healthcare providers treating infants and children, and all specialists treating upper extremity injuries...

Parkinson's disease (PD) is a frequent neurodegenerative process at old age. Accumulation and aggregation of the lipid-binding SNARE complex component alpha-synuclein (SNCA) underlies this vulnerability and defines stages of disease progression. Determinants of SNCA levels and mechanisms of SNCA neurotoxicity are intensely investigated. In view of physiological SNCA roles in blood to modulate vesicle release, we studied blood samples from a new large pedigree with SNCA gene duplication (PARK4 mutation), to identify effects of SNCA gain-of-function as potential disease biomarkers...

The insecticidal toxicities of five essential oils against Pochazia shantungensis adults and nymphs, newly recorded pests, were evaluated. The LC50 values of Thymus vulgaris, Ruta graveolens, Citrus aurantium, Leptospermum petersonii and Achillea millefolium oils were recorded as 57.48, 84.44, 92.58, 113.26 and 125.78 mg/L, respectively, against P. shantungensis nymphs using the leaf dipping bioassay, and 75.80, 109.86, 113.26, 145.06 and 153.74 mg/L, respectively, against P. shantungensis adults using the spray bioassay method...

Aquaculture industry has undergone a rapid and continuous growth during the last decade due to increased demands in seafood consumption and reduced pelagic fish production. Aquaculture sector can provide products with a consistent flow and quality standards to cover the market's needs. Modified atmosphere packaging (MAP) technique has evolved over the last two decades and many reports indicate its beneficial effect on many quality parameters during fish and shellfish preservation. The use of MAP can clearly offer an advantage to the safer distribution of quality aqua cultured fishery products...

Asteraceae (Achillea millefolium and Calendula officinalis) and Lamiaceae (Melissa officinalis and Origanum majorana) extracts were obtained by applying two sequential extraction processes: supercritical fluid extraction with carbon dioxide, followed by ultrasonic assisted extraction using green solvents (ethanol and ethanol:water 50:50). The extracts were analyzed in terms of the total content of phenolic compounds and the content of flavonoids; the volatile oil composition of supercritical extracts was analyzed by gas chromatography and the antioxidant capacity and cell toxicity was determined...

IGF-IR is highly associated with the behaviour of breast cancer cells. In ERα-positive breast cancer, IGF-IR is present at high levels. In clinical practice, prolonged treatment with anti-estrogen agents results in resistance to the therapy with activation of alternative signaling pathways. Receptor Tyrosine Kinases, and especially IGF-IR, have crucial roles in these processes. Here, we report a nodal role of IGF-IR in the regulation of ERα-positive breast cancer cell aggressiveness and the regulation of expression levels of several extracellular matrix molecules...

Platinum(ii) complexes of the formula PtLCl2 [L = 2-(2'-pyridyl)quinoxaline, (pqx) (1), 2,(2'-pyridyl)benzo[g]quinoxaline, (pbqx) (3) and 2,(2'-pyridyl)quinoline, (pqn) (5)] were synthesized and characterized by spectroscopic and X-ray diffraction methods. Also, monodentate coordination of the ligands pqx and pbqx formed the complexes trans-Pt(DMSO)pqxCl2 (2) and trans-Pt(DMSO)pbqxCl2 (4) as it is indicated from X-ray crystal structure and NMR studies. The reaction of the complexes (1), (3) and (5) with DMSO-d6 revealed a ligand-release solvolysis, which was studied by means of NMR techniques...

Micro-RNAs (miRNAs) have a complex role in carcinogenesis and tumour progression. Several miRNAs, such as miR-221, miR-27b and miR-132, have been implicated in the regulation of VEGF tumour angiogenic activity. In this pilot study, we assessed angiogenesis and DLL4+ vascular maturation index (VMI) in breast cancer tissues, in parallel with the plasma levels of the above-mentioned miRNAs. Significantly higher than control samples pre-operative levels were recorded in 10/11, 7/11 and 9/11 cases for the miR-221, miR-27b and miR-132, respectively...
