Influence of Endurance and Resistance Exercise Order on the Postexercise Hemodynamic Responses in Hypertensive Women

Abstract Menêses, AL, Forjaz CL, Lima, PFM, Batista, RMF, Monteiro, MF, and Ritti-Dias, RM. Influence of endurance and resistance exercise order on the postexercise hemodynamic responses in hypertensive women. J Strength Cond Res 29(3): 612–618, 2015—The study aims to evaluate the effects of the order of endurance and resistance exercises on postexercise blood pressure (BP) and hemodynamics in hypertensive women. Nineteen hypertensive women underwent 3 sessions: control (50 minutes rest), endurance (50–60% of heart rate reserve) followed by resistance exercise (50% of 1 repetition maximum) (E + R), and resistance followed by endurance exercise (R + E). Before and 30 minutes after each session, BP, peripheral vascular resistance, cardiac output, stroke volume, and heart rate were measured. Postexercise increases in systolic (E + R: +1 ± 3 mm Hg and R + E: +3 ± 3 mm Hg), diastolic (E + R: +3 ± 1 mm Hg and R + E: +3 ± 2 mm Hg), and mean BP (E + R: +3 ± 1 mm Hg and R + E: +3 ± 2 mm Hg) were significantly lower after the exercise sessions compared with the control session (p ⩽ 0.05). The exercise sessions abolished the increases in peripheral vascular resistance (E + R: +0.00 ± 0.04 mm Hg·min−1·L−1 and R + E: +0.05 ± 0.05 mm Hg·min−1·L−1) and the decreases in cardiac output (E + R: +0.04 ± 0.28 L·min−1 and R + E: −0.26 ± 0.28 L·min−1) observed after the control session (p ⩽ 0.05). After the exercise sessions, stroke volume decreased (E + R: −14 ± 3 ml and R + E: −9 ± 4 ml) and heart rate increased (E + R: +5 ± 1 b·min−1 and R + E: +4 ± 1 b·min−1) in comparison with the control session (p ⩽ 0.05). For all the variables, there were no significant differences between the exercise sessions. Regardless of the order of endurance and resistance exercises, combined exercise sessions abolished increases in BP observed in a control condition due to a reduction in peripheral vascular resistance and increases in cardiac output. Thus, combined exercises should be prescribed to individuals with hypertension to control their BP, regardless of the order they are accomplished.
Heme minimizes Parkinson’s disease-associated toxicity by inducing a conformational distortion in the oligomers of alpha-Synuclein

Aggregation of the intrinsically disordered protein alpha-Synuclein (α-Syn) into insoluble fibrils with a cross-β sheet amyloid structure plays a key role in the neuronal pathology of Parkinson’s disease (PD). The fibrillation pathway of α-Syn encompasses a multitude of transient oligomeric forms differing in size, secondary structure, hydrophobic exposure and toxicity. According to a recent solid state NMR study, the fibrillating unit of α-Syn contains the core residues of the protein arranged into in-register parallel β sheets with a unique Greek key topology. Here, we have shown that the physiologically available small molecule heme (hemin chloride) when added at sub-stoichiometric ratios to either monomeric or aggregated α-Syn, arrests its aggregation in an oligomeric state, which is minimally toxic. Using cryo-EM, we observed that these heme-induced oligomers are ‘mace’-shaped and consist of approximately four monomers. However, the presence of a crucial twist or contortion in their Greek key structural architecture prevents further hierarchical appending into annular oligomers and protofilament formation. We confirm using a His50Gln mutant that the binding of heme onto His50 is crucial in inflicting the structural distortion and is responsible for the stabilization of the non-toxic and off-pathway α-Syn oligomers. We believe that this study provides a novel strategy of developing a therapeutic solution of PD, which has been elusive so far.
Methotrexate in local treatment of cervical heterotopic pregnancy with successful perinatal outcome: Case report

This case report describes a case of heterotopic cervical ectopic pregnancy in a nulliparous woman that was successfully treated with single‐dose local, intra‐amniotic methotrexate injection in the gestational sac. Pregnancy was achieved spontaneously. The patient had previously undergone hysteroscopic myomectomy. By using local, single‐dose treatment we avoided the continued effects of the drug on the intrauterine pregnancy and the possible adverse effect of systemically applied methotrexate. The treatment resulted in the term vaginal delivery of a healthy child and preserved the patient's fertility for future pregnancies.
p53 expression is a strong marker of inferior survival in de novo diffuse large B-cell lymphoma and may have enhanced negative effect with MYC coexpression: a single institutional clinicopathologic study.

OBJECTIVES To examine interactions among clinical factors and pathologic biomarkers in predicting the outcome of patients with diffuse large B-cell lymphoma (DLBCL) treated with rituximab-based immunochemotherapy. METHODS In 85 patients treated at a single institution, clinicopathologic variables were analyzed, including the International Prognostic Index (IPI); germinal/nongerminal center phenotype; MYC, p53, BCL2, Ki-67, and Epstein-Barr virus (EBV) expression; and MYC translocation status. RESULTS In univariate analysis, overall survival (OS) was worse for patients with high IPI scores, nongerminal center phenotype, high MYC and p53 expression by immunohistochemistry, and EBV positivity. In multivariable analysis, p53 expression was the strongest prognostic factor (P < .05) independent of IPI and cell of origin. A significant positive association between p53 and MYC expression was found. Moreover, coexpression of p53/MYC had an enhanced negative effect on OS independent of BCL2 expression. CONCLUSIONS Immunohistochemical assessment of p53, particularly in combination with MYC, could be useful in identifying a high-risk subgroup of DLBCL.
NOTES ON NEGLECTED AND UNDERUTILIZED CROPS Cultivated emmer wheat (Triticum dicoccon Schrank), an old crop with promising future: a review

Cultivated emmer wheat, Triticum dicoccon Schrank, a tetraploid species with hulled grain, has been largely cultivated during seven millennia in the Middle-East, Central and West Asia, and Europe. It has been largely replaced by hulless species and is now a minor crop, with the exception of some countries like India, Ethiopia and Yemen, where its grain is used for preparing traditional foods. Nutritional qualities and specific taste and flavor of emmer wheat products have led to a recent development of the cultivation in some European countries. Emmer wheat also possesses valuable traits of resistance to pests and diseases and tolerance to abiotic stresses and is increasingly used as a reservoir of useful genes in wheat breeding. In the present article, a review concerning taxonomy, diversity and history of cultivation of emmer wheat is reported. Grain characteristics and valuable agronomic traits are described. Some successful examples of emmer wheat utilization for the development of durum or bread wheat cultivars are examined, and the perspectives in using emmer wheat as health food and for the development of new breeding germplasm are
A case of mucocutaneous leishmaniasis in Saudi Arabia caused by Leishmania major and its response to treatment

A case is presented of mucocutaneous leishmaniasis in a male Saudi infant caused by Leishmania major. The extensive lesions of the nose and right cheek healed rapidly and completely following parenteral therapy with sodium stibogluconate (Pentostam®). This appears to be the first case of mucocutaneous leishmaniasis described in the Kingdom of Saudi Arabia. A brief comparison is drawn with the condition as described in other areas.
Abdominal Tuberculosis : Clinical Presentation , Diagnosis , Outcome and Experience with 11 Cases

2015 May 12 Accepted Abstract Tuberculosis is a common health problem. Abdominal tuberculosis constitutes about 2% of all tubercular cases and it’s the sixth most common extrapulmonary tuberculosis. The aim of this study was to evaluate the clinical presentation, diagnosis and effective treatment of abdominal tuberculosis. This is a retrospective study including 11 patients (4males and 7 females), with clinical features of abdominal tuberculosis. They were divided according to the clinical presentation into two groups. The first group included patients presented as acute abdominal pain mainly due to bowel obstruction or as peritonitis and were prepared and treated by explorative laparotomy and definitive diagnosis of abdominal TB was made by tissue biopsy. The second group included patients with chronic symptoms. The results observed in this study were that abdominal pain was the commonest symptom followed by abdominal distention, anorexia, weight loss and fever. Tender right lower abdominal quadrant was found in 7 patients(63.6%) and right iliac fossa mass was found in 3 patients (27.3%). Explorative laparotomy was needed for 5 patients (45.5%) who presented as acute abdomen. Strictures were found in 3 patients (27.3%), adhesion in one patient (9.1%) and peritonitis caused by perforation in the terminal ileum was recorded in one patient. Ascitic fluid analysis for AFB stain and culture confirm the diagnosis of abdominal tuberculosis in patients who presented with chronic symptoms of tuberculosis. All patients showed good response to ATT therapy. No mortality or recurrence was recorded during ATT treatment or during follow up period. We concluded that abdominal tuberculosis is difficult to diagnose due to vague and non specific symptoms and signs such as abdominal pain, anorexia, weight loss and fever. High index of suspicion and clinical awareness is needed for definite diagnosis which depends on PCR or histopathology or AFB stain.
Effects of prebiotics and probiotics on the performance and bacterial colonization of broiler chickens

A study was undertaken to evaluate the effects of Neoxyval (antimicrobial growth promoter (AGP)), TechnoMos (prebiotic), GalliPro (probiotic) and a mixture of TechnoMos and GalliPro (symbiotic) on growth performance, carcass yield, histomorphology and intestinal bacterial counts in broilers (0 d to 42 d). Two hundred day-old Ross (308) broilers were allocated to five experimental treatments: T1 = control (CONT), T2 = T1 + Neoxyval, T3 = T1 + Gallipro, T4 = T1+ TechnoMos and T5 = T1+ Gallipro+ TechnoMos. The results revealed that birds that received T2, T4 and T3 gained more weight and converted feed more efficiently than those in T1 and T5. Longer ileal villi (492.9 µm) were recorded in birds that received T4 compared with T1 (424.7 µm) and T2 (439.9 µm). Conversely, jejunal villi length and width were not influenced by treatment. T3 eliminated Clostridium perfringens from the ileum, but not from the caecum. Generally, birds that received T3 and T5 performed similar to the AGP group, T2. The results from this study indicated that the probiotic (T3) and prebiotic (T4) used in this trial could serve as alternatives to AGP (T2). Enhancement in the performance of broilers could be explained partially by improvement in intestinal morphology and microbial balance associated with modulation of intestinal microflora and inhibition of pathogens.
The antinociceptive effects of ferulic acid on neuropathic pain: involvement of descending monoaminergic system and opioid receptors

Neuropathic pain can be considered as a form of chronic stress that may share common neuropathological mechanism between pain and stress-related depression and respond to similar treatment. Ferulic acid (FA) is a major active component of angelica sinensis and has been reported to exert antidepressant-like effects; however, it remains unknown whether FA ameliorate chronic constriction injury (CCI)-induced neuropathic pain and the involvement of descending monoaminergic system and opioid receptors. Chronic treatment with FA (20, 40 and 80 mg/kg) ameliorated mechanical allodynia and thermal hyperalgesia in von Frey hair and hot plate tasks, accompanied by increasing spinal noradrenaline (NA) and serotonin (5-HT) levels. Subsequent study suggested that treatment of CCI animals with 40 and 80 mg/kg FA also inhibited spinal MAO-A levels. FA's effects on mechanical allodynia or thermal hyperalgesiawas blocked by 6-hydroxydopamine (6-OHDA) or p-chlorophenylalanine (PCPA) via pharmacological depletion of spinal noradrenaline or serotonin. Moreover, the anti-allodynic action of FA on mechanical stimuli was prevented by pre-treatment with beta2-adrenoceptor antagonist ICI 118,551, or by the delta-opioid receptor antagonist naltrindole. While the anti-hyperalgesia on thermal stimuli induced by FA was blocked by pre-treatment with 5-HT1A receptor antagonist WAY-100635, or with the irreversible mu-opioid receptor antagonist beta-funaltrexamine. These results suggest that the effect of FA on neuropathic pain is potentially mediated via amelioration of the descending monoaminergic system that coupled with spinal beta2- and 5-HT1A receptors and the downstream delta- and mu-opioid receptors differentially.
Medical error: the second victim

Personal view p 812 When I was a house officer another resident failed to identify the electrocardiographic signs of the pericardial tamponade that would rush the patient to the operating room late that night. The news spread rapidly, the case tried repeatedly before an incredulous jury of peers, who returned a summary judgment of incompetence. I was dismayed by the lack of sympathy and wondered secretly if I could have made the same mistake—and, like the hapless resident, become the second victim of the error. Strangely, there is no place for mistakes in modern medicine. Society has entrusted physicians with the burden of understanding and dealing with illness. Although it is often said that “doctors are only human,” technological wonders, the apparent precision of laboratory tests, and innovations that present tangible images of illness have in fact created an expectation of perfection. Patients, who have an understandable need to consider their doctors infallible, have colluded with doctors to deny the existence of error. Hospitals react to every error as an anomaly, for which the solution is to ferret out and blame an individual, with a promise that “it will never happen again. ” Paradoxically, this approach has diverted attention …
Polynomial algorithm for the k-cut problem

The k-cut problem is to find a partition of an edge weighted graph into k nonempty components, such that the total edge weight between components is minimum. This problem is NP-complete for arbitrary k and its version involving fixing a vertex in each component is NP hard even for k=3. A polynomial algorithm for the case of a fixed k is presented. <<ETX>>
Nottingham trial of faecal occult blood testing for colorectal cancer: a 20-year follow-up

Background Three large randomised trials have shown that screening for colorectal cancer (CRC) using the faecal occult blood test (FOBt) can reduce the mortality from this disease. The largest of these trials, conducted in Nottingham since 1981, randomised 152 850 individuals between the ages of 45 and 74 years to an intervention arm receiving biennial Haemoccult (FOB) test kit or to a control arm. In 2006, the National Bowel Cancer Screening Programme was launched in England using the FOBt, with the expectation that it will reduce CRC mortality. Aims To compare the CRC mortality and incidence in the intervention arm with the control arm after long-term follow-up. Methods The 152 850 randomised individuals were followed up through local health records and central flagging (Office for National Statistics). Results At a median follow-up of 19.5 years there was a 13% reduction in CRC mortality (95% CI 3% to 22%) in the intervention arm despite an uptake at first invitation of approximately 57%. The CRC mortality reduction in those accepting the first screening test, adjusted for the rate of non-compliers, was 18%. There was no significant difference in mortality from causes other than CRC between the intervention and control arms. Despite removing 615 adenomas >10 mm in size from the intervention arm, there was no significant difference in CRC incidence between the two arms. Conclusions Although the reduction in CRC mortality was sustained, further follow-up of the screened population has not shown a significant reduction in the CRC incidence. Moreover, despite the removal of many large adenomas there was no reduction in the incidence of invasive cancer which was independent of sex and site of the tumour.
Hematologic and Plasma Biochemical Reference Values for Three Species of Black Cockatoos (Calyptorhynchus species)

Abstract: Black cockatoos in southwest Western Australia face population declines as a result of habitat loss and fragmentation, poaching, competition with other species, vehicle strikes, and shootings. In this study, hematologic and plasma biochemical reference values were determined for 3 endemic Western Australian black cockatoo species: Carnaby's cockatoo (Calyptorhynchus latirostris) (n = 34), Baudin's cockatoo (Calyptorhynchus baudinii) (n = 22), and forest red-tailed black cockatoo (Calyptorhynchus banksii naso) (n = 22). Significant sex-related differences were detected in Carnaby's cockatoos, and differences were also found among the 3 species. The forest red-tailed black cockatoos showed a markedly greater eosinophil count than did the 2 white-tailed species. Blood values from samples obtained by different collection methods differed significantly for Carnaby's cockatoos, which indicates that anesthesia may affect analyte values and that collection methods should remain consistent. The results of this study will be useful for clinically evaluating wild black cockatoos that are undergoing rehabilitation for release and will provide baseline data for future investigations of free-living black cockatoo health.
On the acceleration of land subsidence rate in Semarang City as detected from GPS surveys

Land subsidence is not a new phenomenon for Semarang the capital city of Central Java Province with recent population of about 1.5 million. Some report said the subsidence in Semarang probably is occurring for more than 100 years. Geodetic surveys such as GPS Surveys can detect land subsidence accurately. Land subsidence in Semarang exhibits spatial and temporal variations with the typical average rates of about 3 to 10 cm/year until recently it seem the acceleration existed in some region of the city. This acceleration will increase the risk of negative consequences from the land subsidence. This paper present and discuss the acceleration of land subsidence in Semarang as detected from GPS Surveys. The surveys have been conducted in 2008, 2009, 2010, 2012, 2016 and 2017. From 2008 to 2012 the subsidence generally follow linier rates while from 2012 to 2017 seem they are accelerating. The northern eastern region of Semarang along the coastal area still exhibits relatively higher rates of subsidence along with acceleration in rates compare to others region. Ground water exploitation is suspected to be the causes of that land subsidence phenomenon in Semarang city
Changes in duration of developmental phases of durum wheat caused by breeding in Spain and Italy during the 20th century and its impact on yield.

BACKGROUND AND AIMS Although the apical development of wheat has been widely described, studies analysing how genetic breeding over the 20th century influenced the developmental phases and its consequences on yield generation are lacking, especially for durum wheat under field conditions in Mediterranean environments. The aims of this study were to analyse the effects of breeding in Spain and Italy on crop development during the last century, to determine whether or not breeding significantly altered the developmental phases between sowing and maturity, and to evaluate the importance of each phase in determining the number of grains per spike of durum wheat (Triticum durum) cultivars representing the germplasm grown throughout the 20th century in Spain and Italy. METHODS Eight field experiments were carried out during 4 years in two contrasting latitudes (Lleida and Granada, Spain). Plant material consisted of 24 durum wheat cultivars (12 Italian and 12 Spanish) grown throughout the 20th century in Spain and Italy. KEY RESULTS In Spanish materials, breeding reduced the duration of the period from sowing to anthesis, placing the grain-filling period in better conditions. In those cultivars, the sub-phase sowing-terminal spikelet formation was reduced while the duration of the period from booting to anthesis was increased. The number of grains per spike increased by 23 % from old to modern cultivars, by changes in the number of grains per spikelet in both Spanish and Italian cultivars. Floral abortion from booting to anthesis diminished by 24 % from old to modern cultivars, and grain setting increased by 13 %. CONCLUSIONS The results suggest that breeding reduced not only plant height, but also the time to anthesis. By extending the duration of the phase from booting to anthesis, which was associated with an increase in spike dry weight and grains per spike, it suggests that future increases in spike fertility could be achieved by enlarging that phase.
Synbiotic preparation in men suffering from functional constipation: a randomised controlled trial.

BACKGROUND Evaluating the effects of a commercially available synbiotic preparation (contains both prebiotic and probiotic elements) on functional constipation in males. METHODS In a randomised controlled trial, a total of 66 adult men with functional constipation were equally allocated to receive a synbiotic mixture or a placebo. The synbiotic mixture or placebo was given as capsules with the same shape and colour, and patients received the capsules twice a day for 4 weeks. RESULTS A total of 60 patients (31 in the synbiotic group) completed the study. At baseline evaluation, there was no significant difference between the mean stool frequency per week in synbiotic and placebo groups [mean difference of 0.11 times (95% CI: -0.31-0.55), p = 0.58]. However, mean stool frequency increased significantly at weeks 2 [mean difference of 1.32 times (95% CI: 0.21-2.43)] and 4 [mean difference of 1.58 times (95% CI: 0.18-2.99)] in the synbiotic group compared with the placebo group (p = 0.02). A significant difference (p = 0.006) was found at weeks 2 [mean difference of 0.83 (95% CI: 0.20-1.45)] and 4 [mean difference of 0.91 (95% CI: 0.3-1.51)] between the synbiotic and placebo groups regarding the Bristol stool form score. No adverse effect was seen in the synbiotic group. CONCLUSION The results of this study indicated that this specific commercial product seemed to be effective in increasing stool frequency and improving consistency in this sample of males with functional constipation. However, further studies with longer follow ups, and including females and elderly patients are required to confirm the efficacy of this product for treatment of functional constipation.
Lessons learned from a randomized trial of airway secretion clearance techniques in cystic fibrosis

Airway secretion clearance therapies are a cornerstone of cystic fibrosis care, however longitudinal comparative studies are rare. Our objectives were to compare three therapies [postural drainage and percussion: (postural drainage), flutter device (FD), and high frequency chest wall oscillation: (vest)], by studying (1) change in pulmonary function; (2) time to need for intravenous (IV) antibiotics, (3) use of pulmonary therapies, (4) adherence to treatment, (5) treatment satisfaction, and (6) quality of life.
10TH INTERNATIONAL PROSTATE CANCER UPDATE Prostate Cancer: Epidemiology and Screening

The wealth of information that can be gleaned from examination of prostate specimens obtained by needle biopsy and following radical prostatectomy underscores the importance of the urologist and the pathologist having an excellent working relationship. M. Scott Lucia, MD, stated that despite the dramatic increase in the ability to diagnose prostate cancer, in public awareness, and in the numbers of radical prostatectomies being performed, we are still severely limited in our ability to accurately predict in which patients this form of therapy will fail.
