Genomewide identification of genes involved in the potato response to drought indicates functional evolutionary conservation with Arabidopsis plants

Summary Potato is one of the four most important food crop plants worldwide and is strongly affected by drought. The following two pairs of potato cultivars, which are related in ancestry but show different drought tolerances, were chosen for comparative gene expression studies: Gwiazda/Oberon and Tajfun/Owacja. Comparative RNA‐seq analyses of gene expression differences in the transcriptomes obtained from drought‐tolerant versus drought‐sensitive plants during water shortage conditions were performed. The 23 top‐ranking genes were selected, 22 of which are described here as novel potato drought‐responsive genes. Moreover, all but one of the potato genes selected have homologues in the Arabidopsis genome. Of the seven tested A. thaliana mutants with altered expression of the selected homologous genes, compared to the wild‐type Arabidopsis plants, six showed an improved tolerance to drought. These genes encode carbohydrate transporter, mitogen‐activated protein kinase kinase kinase 15 (MAPKKK15), serine carboxypeptidase‐like 19 protein (SCPL19), armadillo/beta‐catenin‐like repeat‐containing protein, high‐affinity nitrate transporter 2.7 and nonspecific lipid transfer protein type 2 (nsLPT). The evolutionary conservation of the functions of the selected genes in the plant response to drought confirms the importance of these identified potato genes in the ability of plants to cope with water shortage conditions. Knowledge regarding these gene functions can be used to generate potato cultivars that are resistant to unfavourable conditions. The approach used in this work and the obtained results allowed for the identification of new players in the plant response to drought.
Rib fractures in the elderly.

BACKGROUND We sought to ascertain the extent to which advanced age influences the morbidity and mortality after rib fractures (fxs), to define the relationship between number of rib fractures and morbidity and mortality, and to evaluate the influence of analgesic technique on outcome. METHODS A retrospective cohort study involving all 277 patients > or = 65 years old with rib fxs admitted to a Level I trauma center over 10 years was undertaken. The control group consisted of 187 randomly selected patients, 18 to 64 years old, with rib fxs admitted over the same time period. Outcomes included pulmonary complications, number of ventilator days, length of intensive care unit and hospital stay (LOS), disposition, and mortality. The specific analgesic technique used was also examined. RESULTS The two groups had similar mean number of rib fxs (3.6 elderly vs. 4.0 young), mean chest Abbreviated Injury Scores (3.0 vs. 3.0), and mean Injury Severity Score (20.7 vs. 21.4). However, mean number of ventilator days (4.3 vs. 3.1), intensive care unit days (6.1 vs. 4.0), and LOS (15.4 vs. 10.7 days) were longer for the elderly patients. Pneumonia occurred in 31% of elderly versus 17% of young (p < 0.01) and mortality was 22% for the elderly versus 10% for the young (p < 0.01). Mortality and pneumonia rates increased as the number of rib fxs increased with and odds ratio for death of 1.19 and for pneumonia of 1.16 per each additional rib fracture (p < 0.001). The use of epidural analgesia in the elderly (LOS >2 days) was associated with a 10% mortality versus 16% without the use of an epidural (p = 0.28). In the younger group (LOS >2 days), mortality with and without the use of an epidural was 0% and 5%, respectively. CONCLUSION Elderly patients who sustain blunt chest trauma with rib fxs have twice the mortality and thoracic morbidity of younger patients with similar injuries. For each additional rib fracture in the elderly, mortality increases by 19% and the risk of pneumonia by 27%. As the number of rib fractures increases, there is a significant increase in morbidity and mortality in both groups, but with different patterns for each group. Further prospective study is needed to determine the utility of epidural analgesia in this population.
Use of herbs and herbal products by Hispanics in south Florida.

OBJECTIVES To provide insight into the use of herbs by Hispanic Americans, identify specific herbal products that health care professionals should inquire about in this population, and assess information sources and expenditures. DESIGN Cross-sectional survey. SETTING South Florida. PARTICIPANTS Convenience sample of 200 Hispanic adults. INTERVENTIONS Participants completed a descriptive, self-administered survey. MAIN OUTCOME MEASURES Specific herbs and herbal remedies use, monthly expenditures, sources of information, and attitudes and beliefs regarding herbs. RESULTS Of the 200 surveys that were distributed, 142 were completed for a response rate of 71%. Of the respondents, 75% reported using at least one herb in the last 12 months. Women between 25 and 34 years of age were most likely to be herb users (P = .001), while men in that age group were the least likely (P = .013). Chamomile (58.5%) and aloe vera (45.3%) were used most frequently. Two frequently used herbs--linden (35.8%) and star anise (33.0%)--are ones that are generally not well known to health care professionals. Family tradition (36%) and safety (17%) were the major reasons for use of herb/herbal remedies. Participants most commonly reported spending 25 dollars or less per month for herbs and herbal products. CONCLUSION Hispanics in south Florida reported using herbs and herbal products at a higher rate than that those reported previously for the general population of the United States. While money spent on herbs and herbal products was generally minimal, study participants had a disconcerting level of confidence in the safety and efficacy of herbal products.
bcl-2 expression in the spectrum of preinvasive breast lesions.

BACKGROUND The bcl-2 gene encodes for a protein that blocks apoptosis. Although the bcl-2 protein has been identified in some invasive breast cancers, its expression in preinvasive breast lesions has not been well characterized. METHODS We studied bcl-2 expression using immunohistochemistry in cases of normal breast tissue (n = 10), ductal hyperplasia (n = 18), atypical ductal hyperplasia (ADH) (n = 10), atypical lobular hyperplasia/lobular carcinoma in situ (lobular neoplasia, LN) (n = 10), and ductal carcinoma in situ (DCIS) (n = 42). We also related bcl-2 expression to p53 expression in these lesions because the p53 gene is altered in many invasive breast cancers and is also involved in the regulation of apoptosis. RESULTS bcl-2 was consistently expressed in the epithelial cells in all normal breast tissue, ductal hyperplasia, ADH, and LN lesions. In contrast, bcl-2 expression was present in 76% of the DCIS cases and was related to the histologic grade of DCIS. Staining for bcl-2 was observed in 100% of the well differentiated DCIS cases, 90% of intermediately differentiated cases, and 33% of poorly differentiated cases (P < 0.001). No immunoreactivity for the p53 protein was seen in any of the cases of normal breast tissue, ductal hyperplasia, ADH, or LN lesions. However, 24% of the DCIS cases were p53 positive. The bcl-2+/p53- phenotype, as seen in all cases of normal breast tissue, ductal hyperplasia, ADH, and LN was also observed in 67% of the DCIS cases. In contrast, the remaining 33% of DCIS cases showed combinations of bcl-2 and p53 expression that differed from that of normal breast epithelium and the other pathologic lesions studied. Most lesions with altered bcl-2/p53 phenotypes, including all bcl-2-/p53+ cases, represented examples of poorly differentiated DCIS. CONCLUSIONS The bcl-2 protein is consistently expressed in normal breast epithelium, ductal hyperplasia, ADH, and LN. bcl-2 expression is variable in DCIS. Among DCIS cases, bcl-2 is most common in well differentiated and intermediately differentiated lesions. Most DCIS lesions are bcl-2+ and p53-, similar to normal epithelium, benign proliferative lesions, and LN. However, a minority of DCIS lesions show combinations of bcl-2 and p53 expression that differ from normal breast epithelium and from the other pathologic lesions studied. It is possible that such lesions may represent a subset of DCIS in which the regulation of apoptosis is no longer under normal control mechanisms, resulting in enhanced tumor cell survival and tumor growth.
The prevalence and association of chronic kidney disease and diabetes in liver cirrhosis using different estimated glomerular filtration rate equation

Background Chronic kidney disease (CKD) in cirrhosis is one of the dreaded complications associated with a steep rise in mortality and morbidity, including diabetes. There are limited data on the prevalence of CKD and the association with diabetes in outpatients with cirrhosis. Methodology This is a cross-sectional study of 7,440 adult liver cirrhosis patients enrolled from August 2001 to April 2010 in a medical center. Case control matching by age and sex with 1,967 pairs, and conditional logistic regression for odds of diabetes was analyzed using adjusted model. Results CKD was present in 46.0%, 45.7% and 45.6% of the study population using the MDRD-6, CKD-EPI and MDRD-4 estimated glomerular filtration rate (eGFR) equations, respectively. Using a conditional logistic regression model after adjusting for other risk factors, odds for diabetes increased significantly compared with non-CKD in CKD stage 3 to 5 (stage 3~5) based on MDRD-6–adjusted model, ORs were: stage 3~5, 2.34 (95% CI, 1.78-3.01); MDRD-4–adjusted model, ORs were: stage 3~5, 8.51 (95% CI, 5.63-11.4); CKD-EPI–adjusted model, ORs were: stage 3~5, 8.61 (95% CI, 5.13-13.9). Conclusion In cirrhosis patients, prevalence of diabetes was higher in patients with advanced stage of CKD. For patients with cirrhosis, patients with CKD stages 3~5 defined by MDRD-4, MDRD-6, and CKD-EPI eGFR equations had increased risk for diabetes. More severe cirrhosis, indicated by the Child-Turcott-Pugh classification was also accompanied by an increased risk for diabetes.
Increasing physical activity in patients with arthritis: a tailored health promotion program

Objective: Despite recent studies showing the benefit of physical activity for people with arthritis, the vast majority of persons with arthritis are not sufficiently physically active. The purpose of this report is to describe a tailored health promotion intervention aimed at increasing physical activity among persons with arthritis. The intervention is designed to be useful for health systems and insurers interested in a chronic disease management program that could be disseminated to large populations of arthritis patients. Methods: The intervention is carried out by a clinician who is designated as the client’s physical activity advocate. The approach emphasizes motivational interviewing, individualized goal setting, tailored strategies for increasing physical activity and for monitoring progress, and a plan of 2 years of follow-up. The intervention includes a standardized assessment of barriers to and strengths supporting increased lifestyle physical activity. A randomized, controlled trial is underway to evaluate the efficacy and cost-effectiveness of this intervention. Conclusion: This intervention is unique in that it implements a program tailored to the individual that focuses on lifestyle physical activity and long-term monitoring. The approach recognizes that persons with arthritis present with varying levels of motivation for change in physical activity and that behavior change can take a long time to become habitual.
Biochemical and histological evidence that methylenedioxymethylamphetamine (MDMA) is toxic to neurons in the rat brain.

(+/-)-3,4-Methylenedioxymethylamphetamine (MDMA) was administered s.c. to rats (10, 20 or 40 mg/kg b. wt.) and guinea pigs (20 mg/kg) twice a day for 4 days, 2 weeks before decapitation. Norepinephrine, dopamine and serotonin (5-HT) levels were assayed in the hippocampus, hypothalamus, striatum and neocortex. In rats, MDMA produced dose-dependent reductions in 5-HT in all brain regions examined. The highest dose also reduced norepinephrine and/or dopamine in some regions. The 20-mg/kg dose of MDMA depleted 5-HT in all regions of the guinea pig brain assayed. In both species, repeated administration of 20 mg/kg of MDMA reduced the Vmax but not the Km of 5-HT uptake 2 weeks after administration. A single 40-mg/kg injection of MDMA depleted 5-HT 2 and 8 weeks after administration to rats in all regions of the brain examined except the hypothalamus. Administration of 80 mg/kg of MDMA twice a day for 2 days to rats depleted striatal 5-HT and dopamine. Brain sections from rats injected with MDMA according to this dosage regimen were stained by the Fink-Heimer method. Degenerating axon terminals and cell bodies were observed in the striatum and somatosensory cortex, respectively. These findings suggest that MDMA is toxic to serotonergic and, to a lesser extent, catecholaminergic neurons. Some neurons that do not contain these transmitters (neocortical neurons) are also affected.
Survival of accommodated cardiac xenografts upon retransplantation into cyclosporine-treated recipients.

BACKGROUND Accommodation designates the survival of vascularized grafts in the presence of circulating antigraft antibodies and complement. In the hamster-to-rat model, accommodation is associated with an ongoing T helper (Th)2 cytokine response and the expression of "protective genes" by the graft endothelial cells and smooth muscle cells. In this report, we tested whether accommodated xenografts would be protected from rejection upon retransplantation into second recipients treated with cyclosporine (CsA), a treatment that does not prolong survival of a fresh hamster heart. METHODS Long-term survival of hamster-to-rat cardiac xenografts was achieved using either CsA plus cobra venom factor (CVF) or CsA plus rapamycin. Xenografts that survived long term in their first recipients were retransplanted into second recipients treated with CsA. RESULTS Long-term xenograft survival in CsA/CVF-treated recipients was associated with an ongoing Th2 response, expression of protective genes, and deposition of elicited xenoreactive antibodies and complement on the graft endothelium. In CsA/rapamycin-treated recipients, long-term xenograft survival occurred in the presence of basal levels of antigraft antibodies and was not associated with a Th2 cytokine response or the expression of protective genes. Xenografts from CsA/CVF-treated rats survived significantly longer upon retransplantation into second recipients treated with CsA (77.3% >10 days) as compared with xenografts from CsA/rapamycin-treated rats (4-11 days) or naive hearts (3-4 days). Moreover, 30-35% of xenografts from CsA/CVF rats survived long term and accommodated in the second recipient. CONCLUSIONS Accommodated xenografts can have significantly prolonged acceptance when retransplanted into second recipients treated with CsA alone; in contrast, naive hearts or hearts that survived long term in first recipients, but did not accommodate, did not survive long term in the second recipients. We suggest that prolonged survival of accommodated xenografts is due to the expression of the protective genes A20, bcl-2 bcl-xL, and heme oxygenase-1 in the xenograft endothelium and possibly smooth muscle cells.
Anterior cruciate ligament reconstruction using quadriceps patellar tendon graft

Eighty-three patients with ACL reconstructions using the quadriceps patellar tendon graft were evaluated in a 10 year (mean, 5.5 years) follow-up study. A five-part analysis, consisting of physical examination, question naire, Genucom analysis, operative note review, and radiographs, was performed. Seventy-six percent were categorized as satisfactory. Ninety-two percent were content with their results, while only 4% were unsatis fied. Ninety-three percent of the patients had no signif icant pain and 95% had no giving way postreconstruc tion. Ninety-two percent had no more than a mild functional deficit. Eighty-seven percent and 90% of the patients had no significant Lachman or pivot shift by examination, respectively. Our results showed no in crease in failure over time (1 to 10 years), although those operated on during the initial 5 years showed more radiographic degenerative changes. Plotting our results in classification systems of other authors yielded success rates as good as or better than those using our own criteria. An objective means by which to quan tify laxity did not reliably correlate with the quantifying of laxity made by physical examination. Only the lack of a formal rehabilitation program greater than 4 months postoperatively and repaired tears of the medial or lateral collateral ligaments proved to be significant risk factors for poor recovery.
Vascularized lymph node transfer for treatment of lymphedema: a comprehensive literature review.

OBJECTIVE A comprehensive literature review of VLNT with updates and comparisons on current application, techniques, results, studies and possible future implications. BACKGROUND Lymphedema is a debilitating condition that often results secondary to treatment of cancer. Unfortunately there is no cure. However, microsurgical procedures such as VLNT has gained popularity as there have been increasing reports that VLNT may help alleviate the severity of lymphedema. METHODS A review of literature was conducted over major medical indices (PubMed-MEDLINE, Factiva, Scopus, Sciencedirect, EMBASE). Search terms were focused on vascularized, lymph node transfer (also autologous, lymph node transplant) to cover both human and animal studies. Each study was verified for the nature of the procedure; a free microsurgical flap containing lymph nodes for the purpose of relieving lymphedema. RESULTS There are human and animal studies that individually report clear benefits, but because of methodological shortcomings comparative studies with uniform patient selection and monitoring are lacking. CONCLUSIONS Although the results with the use of VLNT for treatment of lymphedema have been largely positive, further exploration into standardized protocols for diagnosis, treatment optimization, and patient outcomes assessment is needed.
Denying to the Grave: Why We Ignore the Facts That Will Save Us

IS followers. contextual factors underlie the to which one finds normalcy in cognitive, behavioral, and emotional processes. This book challenges the traditional methodology in risk assessment evalu-ations. It is a very valuable read to any forensic psychiatrist interested in better understanding the role of media in influencing cultural beliefs and modulating considerations in assessing risk in forensic evaluations. The themes reviewed can be used to draw parallels in thinking about the role of social media in shaping social and political beliefs.
Tremor of the mouth floor and anti‐glutamic acid decarboxylase autoantibodies

Involuntary movements of the mouth can present as palatal tremor, which is frequently associated with hypertrophy of the inferior olivary nucleus and can be accompanied by contraction of other muscles of the head. We report the case of a 39‐year‐old man with autoimmune thyroiditis and diabetes who complained of involuntary rhythmic tremor involving the muscles of the floor of the mouth, which interfered with breathing and swallowing. Cerebrospinal fluid (CSF) examination showed the presence of oligoclonal bands and screening for anti‐neuronal antibodies revealed high titres of anti‐glutamic acid decarboxylase autoantibodies (GAD‐Ab). Tremor responded to treatment with benzodiazepines. The correlation between the tremor and antibody positivity is unclear although an alteration of the gabaergic system mediated by the antibodies may be hypothesised on the basis of an inflammatory CSF profile.
Cerebrospinal fluid procalcitonin and severe traumatic brain injury in children

Objective To determine the relationship between cerebrospinal fluid procalcitonin concentration and severe traumatic brain injury in children. Design Prospective, observational clinical study. Setting A multidisciplinary, tertiary-care pediatric intensive care unit. Patients Twenty-eight patients who required external ventricular drainage for management of severe traumatic brain injury (Glasgow Coma Scale score of <8) and 22 control patients for whom lumbar cerebrospinal fluid evaluation excluded possible meningitis. Interventions Standard intracranial pressure-directed neurointensive care, including intraventricular catheter placement and continuous cerebrospinal fluid drainage, was used to manage patients with severe traumatic brain injury. Measurements and Main Results Demographic data including age, mechanism of injury, time of injury, initial Glasgow Coma Scale score, and outcome were collected. Cerebrospinal fluid procalcitonin concentration was determined by immunoluminometric assay. Initial cerebrospinal fluid procalcitonin concentration (median [range]) in patients with severe traumatic brain injury was increased greater than three-fold vs. controls (0.41 ng/mL [0.15–2.14] vs. 0.12 ng/mL [0.00–0.24], p < .001). Initial cerebrospinal fluid procalcitonin concentration among patients with abusive head trauma (0.31 ng/mL [0.29–0.50]) also was increased vs. controls (p < .05), although this increase was less robust than patients with accidental trauma (0.41 ng/mL [0.15–2.14], p < .001 vs. controls). Additional examination of key demographic and outcome variables with a generalized linear regression model was performed for patients with severe traumatic brain injury. Univariate analysis revealed that both time after injury (p < .01) and abusive head trauma as a mechanism of injury (p < .001) were associated with attenuation of the increased cerebrospinal fluid procalcitonin response after traumatic brain injury. Conclusion Cerebrospinal fluid procalcitonin concentration is increased in children after traumatic brain injury. The attenuated increase in cerebrospinal fluid procalcitonin among victims of abusive head trauma warrants further study because it may reflect impairment of endogenous neuroprotective mechanisms or delay in seeking medical attention. The significance of these observations remains to be determined as future studies elucidate the physiologic and mechanistic properties of procalcitonin.
