Cancer therapy: targeting cell cycle regulators.

Cyclins and CDKs play critical roles in DNA synthesis and cell division. Alterations in their function may lead to the disruption of normal cell growth and apoptosis, and subsequently, result in carcinogenesis. Elevated levels of cyclins and CDKs are frequently observed in a wide range of different types of human cancers. Understanding of molecular mechanisms underlying the cell cycle effects in r

Familial Lund frontotemporal dementia caused by C9ORF72 hexanucleotide expansion.

Frontotemporal dementia (FTD) as an important clinical entity was rediscovered in Lund and Manchester in the early 1990s. Here we show that the large Lund pedigree with behavioral variant of frontotemporal dementia previously described with this disorder has an expansion in the recently described C9ORF72 locus on chromosome 9.

Diagnostic Pitfalls at Admission in Patients with Acute Superior Mesenteric Artery Occlusion.

BACKGROUND: Acute superior mesenteric artery (SMA) occlusion leads to acute intestinal ischemia and is associated with high mortality. Early diagnosis is often missed, and confounding factors leading to diagnostic delays need to be highlighted. OBJECTIVES: To identify potential diagnostic laboratory pitfalls at admission in patients with acute SMA occlusion. METHODS: Fifty-five patients with acute

Chloroplast thylakoids reduce glucose uptake and decrease intestinal macromolecular permeability.

Thylakoid membranes, derived from chloroplasts, have previously been shown to retard fat digestion and lower blood glucose levels after oral intake. The purpose of the present study was to investigate the effect of thylakoid membranes on the passage of methyl-glucose, dextran and ovalbumin over rat intestine in vitro using Ussing chambers. The results show that thylakoids retard the passage of eac

Oncological outcome after incidental perforation in radical rectal cancer surgery.

PURPOSE: Identification of risk factors of poor oncological outcome in rectal cancer surgery is of utmost importance. This study examines the impact of incidental perforation on the oncological outcome. METHODS: Using the Swedish Rectal Cancer Registry, patients were selected who received major abdominal surgery for rectal cancer between 1995 and 1997 with registered incidental perforation. A cont

Abnormal auditory forward masking pattern in the brainstem response of individuals with Asperger syndrome.

Abnormal auditory information processing has been reported in individuals with autism spectrum disorders (ASD). In the present study auditory processing was investigated by recording auditory brainstem responses (ABRs) elicited by forward masking in adults diagnosed with Asperger syndrome (AS). Sixteen AS subjects were included in the forward masking experiment and compared to three control groups

Stable refraction and visual acuity in diabetic patients with variable glucose levels under routine care.

Abstract. Purpose: To investigate how refraction and visual acuity may vary in patients with diabetes under routine care. Methods: Fifty-three eyes of 53 patients with various degrees of diabetic retinopathy were examined prospectively on four different occasions within a month. Refraction, best-corrected visual acuity (expressed as logMAR score) and blood glucose were measured on each occasion. I

Analysis of atrial fibrillatory rate during spontaneous episodes of atrial fibrillation in humans using implantable loop recorder electrocardiogram.

Atrial fibrillatory rate (AFR) can predict outcome of interventions for atrial fibrillation (AF); however, AFR behavior at AF onset in humans is poorly described. We studied AFR during spontaneous AF episodes in patients with lone paroxysmal AF who received implantable loop recorders and had AF episodes of 1 hour or more recorded (n=4). Mean AFR per minute was assessed from continuous implantable

Patterns and Frequencies of Acquired and Constitutional Uniparental Isodisomies in Pediatric and Adult B-Cell Precursor Acute Lymphoblastic Leukemia.

Single nucleotide polymorphism (SNP) arrays are increasingly being used in clinical routine for genetic analysis of pediatric B-cell precursor acute lymphoblastic leukemias (BCP ALL). Because constitutional DNA is not readily available as a control at the time of diagnosis, it is important to be able to distinguish between acquired and constitutional aberrations in a diagnostic setting. In the pre

Identification and assignment of the absolute configuration of biologically active methyl-branched ketones from limnephilid caddisflies

Glands of the 4th and 5th abdominal sternite of the caddis flies Potamophylax latipennis, Potamophylax cingulatus, and Glyphotaelius pellucidus contain (S)-4-methyl-3-heptanone (4a), (4S,6S)-4,6-dimethyl-3-octanone (4b), and (4S,6S)-4,6-dimethyl-3-nonanone (4c). As shown by gas chromatography coupled with electrophysiological recordings, these ketones elicit a strong response in the insects' anten

Oxygen-dependent copper toxicity: targets in the chlorophyll biosynthesis pathway identified in the copper efflux ATPase CopA deficient mutant

Characterization of a copA(-) mutant in the purple photosynthetic bacterium Rubrivivax gelatinosus under low oxygen or anaerobic conditions, as well as in the human pathogen Neisseria gonorrhoeae identified HemN as a copper toxicity target enzyme in the porphyrin synthesis pathway. Heme synthesis is, however, unaffected by copper under high oxygen tension because of the aerobic coproporphyrinogen

Retinoic acid-inducible gene 1-like receptors in the upper respiratory tract.

Retinoic acid-inducible gene 1-like receptors (RLRs) are a novel family of pattern recognition receptors that include retinoic acid-inducible gene 1 (RIG-1), melanoma differentiation-associated gene 5 (MDA-5), and laboratory of genomics and physiology 2 (LGP-2). The knowledge of RLRs and their function in the human airway is limited. This study explores the role of RLRs in the upper respiratory tr

Regulation of kinin B(2) receptors by bradykinin in human lung cells.

Abstract Bradykinin is a potent mediator of inflammation that has been shown to participate in allergic airway inflammation. The biologic effects of bradykinin are mediated by binding and activating its cognate receptor, the B(2) receptor (B(2)R). In the lung fibroblast cell line IMR-90, binding of bradykinin to the B(2)R triggers down-regulation of the receptor surface expression, suggesting that

Genomic alterations in histopathologically normal breast tissue from BRCA1 mutation carriers may be caused by BRCA1 haploinsufficiency.

Multiple biopsies of normal breast tissue from 10 BRCA1 mutation carriers have been analyzed using array-based comparative genomic hybridization. Normal breast tissue from five age-matched control subjects without a family history of breast cancer was included for reference purposes. We repeatedly found multiple low copy number aberrations at a significantly higher frequency in histopathologically

Delayed reactions to reusable protective gloves.

The materials in plastic protective gloves are thought to cause less contact allergy than rubber gloves. Our aim was to estimate the frequency of delayed reactions to different types of reusable protective gloves among dermatitis patients. 2 x 2 cm pieces of polyvinyl chloride (PVC) gloves, nitrile gloves, and natural rubber latex (NRL) gloves were tested as is in consecutive dermatitis patients t
