BACKGROUND: The problem of managing adhesional small bowel obstruction (ASBO) is still unsolved. A conservative medical attitude is privileged even if it is associated to a high rate of recurrences, while surgery is applied to cases showing no improvement after 48-72 h. Adhesiolysis via laparotomy has been the standard surgical management, but it causes other adhesions in a vicious circle. The aim of the study is to evaluate the advantages of early laparoscopic adhesiolysis as an alternative approach...

Hydraulic architecture imposes a fundamental control on water transport, underpinning plant productivity and survival. The extent to which hydraulic architecture of mature trees acclimates to chronic drought is poorly understood, limiting accuracy in predictions of forest responses to future droughts. We measured seasonal shoot hydraulic performance for multiple years to assess xylem acclimation in mature piñon (Pinus edulis) and juniper (Juniperus monosperma) after 3+ years of precipitation manipulation. Our treatments consisted of water addition (+20% ambient precipitation), partial precipitation-exclusion (-45% ambient precipitation), and exclusion-structure control...

Reliable identification of targets of bacterial regulators is necessary to understand bacterial gene expression regulation. These targets are commonly predicted by searching for high-scoring binding sites in the upstream genomic regions, which typically leads to a large number of false positives. In contrast to the common approach, here we propose a novel concept, where overrepresentation of the scoring distribution that corresponds to the entire searched region is assessed, as opposed to predicting individual binding sites...

Human Fatty Acid Synthase (hFAS) is a megasynthase whose main function is de novo biosynthesis of saturated fatty acids. Interest has been drawn to this enzyme beyond its physiological role due to the association between high levels of hFAS and clinical conditions such as obesity, diabetes and cancer. Thus, it has become an undeniably attractive pharmacological target. Until now, no crystal structure of the complete hFAS is available, hindering attempts to fully understand this protein. Using homology modelling, we built a model of the entire megasynthase, encompassing all of its domains, including the Acyl Carrier Protein (ACP) and Thioesterase (TE) mobile domains absent in the crystal structure of mammalian Fatty Acid Synthase (FAS)...

BACKGROUND: We aimed to determine whether synovial fluid (SF) biomarkers can predict the progression of articular cartilage damage as determined by arthroscopic evaluation during and after anterior cruciate ligament (ACL) reconstruction. METHODS: Arthroscopic assessment of articular cartilage damage was performed twice in 62 patients, first during ACL reconstruction and then approximately 2 years later during implant removal for ligament fixation. SF levels of the collagenase-generated cleavage neoepitope of type II collagen (C2C) and proteoglycan glycosaminoglycans keratan sulfate (KS), chondroitin-4-sulfate (Δdi-C4S), and chondroitin-6-sulfate (Δdi-C6S) were measured at ACL reconstruction...

The plant SABATH gene family is a group of O-methyltransferases (O-MTs), which belongs to the S-adenosyl-l-methionine-dependent methyltransferases (SAM-MTs). The resulting reaction products of SABATH genes play an important role in various processes of plant development. In this study, a total of 30 SABATH genes were detected in Salvia miltiorrhiza, which is an important medicinal plant, widely used to treat cardiovascular disease. Multiple sequence alignment and phylogenetic analyses showed that SmSABATH genes could be classified into three groups...

Ovarian cancer is one of the most common gynecological cancers worldwide. It is the third leading cause of cancer among women in India. Metastatic disease to the visceral organs from ovarian cancer occurs as a terminal event in the natural history of the disease. In particular, spread to the bone and large bowel is infrequently described. The risk of distant metastasis increases in a recurrent setting. We describe a case of a 77-year-old lady, who was diagnosed for ovarian carcinoma in 2007 and underwent primary cytoreductive surgery, stage IIIc...

Congenital hypogonadotropic hypogonadism (CHH) is a rare genetic disease characterized by absent puberty and infertility due to GnRH deficiency, and is often associated with anosmia (Kallmann syndrome, KS). The genetic etiology of CHH is heterogeneous, and more than 30 genes have been implicated in approximately 50% of patients with CHH. We hypothesized that genes encoding axon-guidance proteins containing fibronectin type-III (FN3) domains (similar to ANOS1, the first gene associated with KS), are mutated in CHH...

Zanthoxylum, an ancient economic crop in Asia, has a satisfying aromatic taste and immense medicinal values. A lack of genomic information and genetic markers has limited the evolutionary analysis and genetic improvement of Zanthoxylum species and their close relatives. To better understand the evolution, domestication, and divergence of Zanthoxylum, we present a de novo transcriptome analysis of an elite cultivar of Z. bungeanum using Illumina sequencing; we then developed simple sequence repeat markers for identification of Zanthoxylum...

The widelyvariable phenotypic spectrum and the different severity of symptoms in men with Klinefelter syndrome (KS) suggest a role for epigenetic mediators. Therefore, the aim of this study is to evaluate the possible involvement of miRNAs in the clinical manifestations of KS. To accomplish this, we performed a transcriptome analysis in peripheral blood mononuclear cells (PBMCs) of 10 non-mosaic KS patients, 10 aged-matched healthy men and 10 aged-matched healthy female controls with normal karyotype. After RNA extraction from PBMC and the preparation of RNA libraries, the samples were sequenced using next generation high-throughput sequencing technology...

In humans, the most common sex chromosomal disorder is Klinefelter syndrome (KS), caused by the presence of one or more extra X-chromosomes. KS patients display a varying adult phenotype but usually present with azoospermia due to testicular degeneration, which accelerates at puberty. The timing of the germ cell loss and whether it is caused by dysgenetic fetal development of the testes is not known.We investigated 8 fetal KS testes and found a marked reduction in MAGE-A4-positive pre-spermatogonia compared to testes from 15 age-matched controls, indicating a failure of the gonocytes to differentiate into pre-spermatogonia...
