The VIL gene CRAWLING ELEPHANT controls maturation and differentiation in tomato via polycomb silencing.

VERNALIZATION INSENSITIVE 3-LIKE (VIL) proteins are PHD-finger proteins that recruit the repressor complex Polycomb Repressive Complex 2 (PRC2) to the promoters of target genes. Most known VIL targets are flowering repressor genes. Here, we show that the tomato VIL gene CRAWLING ELEPHANT (CREL) promotes differentiation throughout plant development by facilitating the trimethylation of Histone H3 on lysine 27 (H3K27me3).

Fetal Sacral Ratio: A Novel Method for Prenatal Sonographic Assessment of Sacral Abnormalities.

Objectives: The sacral ratio (SR) was described as a postnatal X-ray-based method to detect sacral abnormalities and predict functional prognosis for fecal continence in children with anorectal malformations (ARMs). The present study aimed to describe a novel method of assessing sonographic fetal sacral ratio (f-SR) in a normal population of fetuses.

Methods: Sixty three-dimensional (3D) ultrasound reconstruction images of the sacrum obtained from routine low-risk scans performed between 21 and 26 weeks of gestation served for measurement.

Characterization of the cytokinin sensor TCSv2 in arabidopsis and tomato.

Background: Hormones are crucial to plant life and development. Being able to follow the plants hormonal response to various stimuli and throughout developmental processes is an important and increasingly widespread tool. The phytohormone cytokinin (CK) has crucial roles in the regulation of plant growth and development.

Coordination of differentiation rate and local patterning in compound-leaf development.

The variability in leaf form in nature is immense. Leaf patterning occurs by differential growth, taking place during a limited window of morphogenetic activity at the leaf marginal meristem. While many regulators have been implicated in the designation of the morphogenetic window and in leaf patterning, how these effectors interact to generate a particular form is still not well understood.

Hormones in tomato leaf development.

Leaf development serves as a model for plant developmental flexibility. Flexible balancing of morphogenesis and differentiation during leaf development results in a large diversity of leaf forms, both between different species and within the same species. This diversity is particularly evident in compound leaves.

Assessment of surgical discharge summaries and evaluation of a new quality improvement model.

Background: Discharge summaries after hospitalization provide the most reliable description and implications of the hospitalization. A concise discharge summary is crucial for maintaining continuity of care through the transition from inpatient to ambulatory care. Discharge summaries often lack information and are imprecise.

Laparoscopic repair of giant diaphragmatic hernias: evolving technical aspects and outcomes.

Background: Laparoscopic repair of giant diaphragmatic hernias (GDH) can be challenging, especially when partial or complete volvulus of the herniated stomach is encountered.

Objectives: To review our experience with laparoscopic repair of GDH, emphasizing preoperative investigation, technical aspects, and outcome.

Methods: We conducted a retrospective review of patients operated on for GDH who were diagnosed when at least half the stomach was found in the mediastinum at surgery.

A role for APETALA1/fruitfull transcription factors in tomato leaf development.

Flexible maturation rates underlie part of the diversity of leaf shape, and tomato (Solanum lycopersicum) leaves are compound due to prolonged organogenic activity of the leaf margin. The CINCINNATA-teosinte branched1, cycloidea, PCF (CIN-TCP) transcription factor lanceolate (LA) restricts this organogenic activity and promotes maturation. Here, we show that tomato APETALA1/fruitfull (AP1/FUL) MADS box genes are involved in tomato leaf development and are repressed by LA.

ENTIRE and GOBLET promote leaflet development in tomato by modulating auxin response.

Compound leaves produce leaflets in a highly controlled yet flexible pattern. Here, we investigate the interaction between auxin, the putative auxin response inhibitor ENTIRE (E, SlIAA9) and the CUC transcription factor GOBLET (GOB) in compound-leaf development in tomato (Solanum lycopersicum). Auxin maxima, monitored by the auxin response sensor DR5, marked and preceded leaflet and lobe initiation.

Thoracic sympathectomy and cardiopulmonary responses to exercise.

The purpose was to study the effect of endoscopic thoracic sympathectomy (ETS) for palmar and/or axillary hyperhidrosis on physiological responses at rest, and during sub-maximal and maximal exercise in ten healthy patients (7 females and 3 males 18-40 years old) with idiopathic palmar and/or axillary hyperhidrosis. T2-T3 thoracoscopic sympathectomy was performed using a simplified one stage bilateral procedure. Physiological variables were recorded at rest and during sub-maximal (steady-state) and maximal treadmill exercise immediately prior to and 70 days (+/-7.

Long-term follow-up on the effect of silastic ring vertical gastroplasty on weight and co-morbidities.

Background: Silastic ring vertical gastroplasty (SRVG) is a simple, effective and reproducible restrictive operation for the treatment of morbid obesity. Over the last years, it has lost its popularity due to the development of adjustable gastric banding systems performed laparoscopically. In order to evaluate the long-term effect of SRVG on weight loss and co-morbidities, we reviewed the results of SRVG operations in our institution.

Octreotide treatment in patients with severe acute pancreatitis.

We investigated the effect of octreotide in the treatment of severe acute pancreatitis in a case-control study. Experimental and clinical studies on the effect of octreotide in the treatment of acute pancreatitis have shown controversial results. Since January 1992, we have been conducting a prospective randomized study on the effect of octreotide in severe acute pancreatitis, in three hospitals in Israel.

Treatment of acute colonic pseudo-obstruction with neostigmine.

Background: Colonic pseudo-obstruction is a poorly understood syndrome, described by Ogilvie, and characterized by signs of large-bowel obstruction, without a mechanical cause. An imbalance in the autonomic nerve supply to the colon has been suggested as the pathophysiology. Recently, promising results with pharmacologic manipulation with neostigmine have been described.

Perforation of the terminal ileum induced by blast injury: delayed diagnosis or delayed perforation?

Blast injuries are rare, and although blast-induced perforations of the bowel have been described in the past, the entity of a delayed perforation caused by an evolving injury has not been reported. We report three men injured by the explosion of a terrorist bombing in open air. They suffered primary blast injuries, which resulted in isolated perforations of the terminal ileum.

Preliminary report of a prospective randomized study of octreotide in the treatment of severe acute pancreatitis.

Background: Experimental and clinical studies on the effect of octreotide in the treatment of patients with acute pancreatitis have presented controversial results. Since January 1992, we have been conducting a prospective randomized study on the clinical effect of octreotide in severe acute pancreatitis, at three hospitals in Israel.

Study Design: The entering criteria included three or more of the Ranson's prognostic signs and computed tomographic findings of severe pancreatitis.

Endogenous plasma growth hormone and the occurrence of pregnancies in patients undergoing in-vitro fertilization and embryo transfer with ovarian stimulation.

This study was undertaken to investigate a possible relationship between endogenous secretion of growth hormone (GH) during ovarian stimulation and treatment outcome in patients undergoing in-vitro fertilization (IVF) and embryo transfer. Plasma samples obtained from 19 women who had successfully completed all stages of IVF/embryo transfer were analysed retrospectively. Based on the increase in GH during treatment, 11 GH responders and eight GH non-responders were identified.

Congenital intraspinal extradural cysts (intraspinal meningocele).

A case of congenital, intraspinal, extradural cyst is reported with pain as the only presenting feature. In the past, the lack of pain has been considered one of the characteristics of these rare lesions. In other reported cases, when pain has been present, it was minimal and never the presenting feature.
