The basic/helix-loop-helix (bHLH) proteins constitute a superfamily of transcription factors that are known to play a range of regulatory roles in eukaryotes. Over the past few decades, many bHLH family genes have been well-characterized in model plants, such as Arabidopsis, rice and tomato. However, the bHLH protein family in peanuts has not yet been systematically identified and characterized. Here, 132 and 129 bHLH proteins were identified from two wild ancestral diploid subgenomes of cultivated tetraploid peanuts, Arachis duranensis (AA) and Arachis ipaensis (BB), respectively...

Exposure to high salinity can trigger acclimation in many plants. Such an adaptative response is greatly advantageous for plants and involves extensive reprogramming at the molecular level. Acclimation allows plants to survive in environments that are prone to increasing salinity. In this study, diploid and autotetraploid Paulownia fortunei seedlings were used to detect alterations in leaf proteins in plants under salt stress. Up to 152 differentially abundant proteins were identified by Multiplex run iTRAQ-based quantitative proteomic and LC-MS/MS methods...

The scars of face and scalp caused by burning often show as 1 large facial-scalp scar. The deltopectoral flap was recognized as one of the first choices for the facial scar reconstruction. However, this flap cannot cross the level of zygomatic arch traditionally when it was transferred with pedicle. When the flap reconstructed the facial-scalp scars with expanded random scalp flap, another flap was often needed to reconstruct the remaining temple and forehead scars. The authors reviewed 24 patients of large facial-scalp scars reconstructed by expanded pedicled deltopectoral flap and scalp flap with several technique improvements...

BACKGROUND: This study aimed to evaluate posttreatment soft-tissue changes in patients with oral cancer with computed tomography (CT). To accomplish that purpose, a scoring system was established, referring to the criteria of lower leg lymphedema (LE). METHODS AND RESULTS: One hundred and six necks in 95 patients who underwent oral oncologic surgery with neck dissection (ND) were analyzed retrospectively using routine follow-up CT images. A two-point scoring system to evaluate soft-tissue changes (so-called "LE score") was established as follows: Necks with a "honeycombing" appearance were assigned 1 point...

The transfer of immunity from mother to offspring is a central way to endow the offspring with increased protection against pathogens. This phenomenon is not only found within the vertebrate domain: in some circumstances, invertebrate mothers can also give their offspring an immune kick-start, which is termed trans-generational immune priming (TGIP). TGIP has been uncovered for a number of invertebrate species, but it is not ubiquitously evident. The reasons for which are not known. In this issue of Molecular Ecology, Tate, Andolfatto, Demuth, and Graham () probe the molecular underpinnings of TGIP in concert with the temporal dynamics of the response in the red flour beetle, Tribolium castaneum, infected with the bacterium Bacillus thuringiensis (Figure )...

OBJECTIVE: To investigate whether multiple detector computed tomography (MDCT) could detect troublesome aberrant posterior sectoral hepatic duct (PHD) communicating with cystic duct (CD). METHODS: The most troublesome bile duct anomaly during cholecystectomy is an aberrant PHD communicating with CD. It has been suggested that an unenhanced small duct between Rouviere's sulcus and CD on MDCT could be coincident to an aberrant PHD communicating with CD. A total of 224 patients who underwent laparotomy with complete lymph node dissection in the hepatoduodenal ligament for hepatobiliary or pancreatic tumor were enrolled...

Elucidating the physiological mechanisms of the irregular yet concerted flowering rhythm of mass flowering tree species in the tropics requires long term monitoring of flowering phenology, exogenous and endogenous environmental factors, as well as identifying interactions and dependencies among these factors. To investigate the proximate factors for floral initiation of mast seeding trees in the tropics, we monitored the expression dynamics of two key flowering genes, meteorological conditions and endogenous resources over two flowering events of Shorea curtisii and Shorea leprosula in the Malay Peninsula...

BACKGROUND: Colorectal cancer (CRC) resembling submucosal tumor (SMT; CRC/SMT) is very rare. Because its biopsy is challenging, accurate preoperative diagnosis is also very rare. CASE PRESENTATION: A 55-year-old woman with a high serum carcinoembryonic antigen level underwent a computed tomography colonoscopy, which showed extrinsic rectum compression. A coronal magnetic resonance image showed a 4-cm low-intensity tumor between her rectum and sacrum. Endoscopic ultrasound (EUS) showed a 30-mm low-echoic lesion originating from the rectum...

Soybean oil is the most widely produced vegetable oil in the world and its content in soybean seed is an important quality trait in breeding programs. More than 100 quantitative trait loci (QTLs) for soybean oil content have been identified. However, most of them are genotype specific and/or environment sensitive. Here, we used both a linkage and association mapping methodology to dissect the genetic basis of seed oil content of Chinese soybean cultivars in various environments in the Jiang-Huai River Valley...

Crops are often subjected to periods of drought stress during their life cycle. However, how stress response mechanisms contribute to the crosstalk between stress signaling pathways and developmental signaling pathways is still unknown. We built a gene co-expression network from a spatio-temporal transcriptomic map of the drought stress response in maize (Zea mays), profiled from three tissues and four developmental stages and characterized hub genes associated with duplication events, selection, and regulatory networks...

The benefit of adding sentinel node biopsy (SNB) to extended pelvic lymph node dissection (ePLND), remains controversial. Aim of our study was to evaluate biochemical recurrence (BCR) after robot-assisted radical prostatectomy (RARP) and ePLND in prostate cancer (PCa) patients, stratified by the application of SNB. The results were compared with the predictions of the updated Memorial Sloan Kettering Cancer Center (MSKCC) nomogram. Methods: Between January 2006 and November 2016, 920 patients underwent RARP with ePLND combined with or without SNB (184 and 736 patients, respectively)...

Ann T Tate, Andrea L Graham
Widespread differential expression of immunological genes is a hallmark of the response to infection in almost all surveyed taxa. However, several challenges remain in the attempt to connect differences in gene expression with functional outcomes like parasite killing and host survival. For example, temporal gene expression patterns are not always monotonic (unidirectional slope), yielding results that qualitatively depend on the time point selected for analysis. They may also be correlated to microbe density, confounding the strength of an immune response and resistance to parasites...

M Joaquina Delás, Gregory J Hannon
Differential expression of long non-coding RNAs (lncRNAs) during differentiation and their misregulation in cancer highlight their potential as cell fate regulators. While some example lncRNAs have been characterized in great detail, the functional in vivo relevance of others has been called into question. Finding functional lncRNAs will most probably require a combination of complementary approaches that will greatly vary depending on their mode of action. In this review, we discuss the different tools available to dissect genetically lncRNA requirements and how each is best suited to studies in particular contexts...

PURPOSE: Orbital volume calculations allow surgeons to design patient-specific implants to correct volume deficits. It is estimated that changes as small as 1 ml in orbital volume can lead to enophthalmos. Awareness of the limitations of orbital volume computed tomography (CT) measurements is critical to differentiate between true volume differences and measurement error. The aim of this study is to analyze the validity and reliability of CT orbital volume measurements. MATERIALS AND METHODS: A total of 12 cadaver orbits were scanned using a standard CT maxillofacial protocol...
