RESUMEN

For the first time, the (d,^{2}He) reaction was successfully used in inverse kinematics to extract the Gamow-Teller transition strength in the ß^{+} direction from an unstable nucleus. The new technique was made possible by the use of an active-target time-projection chamber and a magnetic spectrometer, and opens a path to addressing a range of scientific challenges, including in astrophysics and neutrino physics. In this Letter, the nucleus studied was ^{14}O, and the Gamow-Teller transition strength to ^{14}N was extracted up to an excitation energy of 22 MeV. The data were compared to shell-model and state-of-the-art coupled-cluster calculations. Shell-model calculations reproduce the measured Gamow-Teller strength distribution up to about 15 MeV reasonably well, after the application of a phenomenological quenching factor. In a significant step forward to better understand this quenching, the coupled-cluster calculation reproduces the full strength distribution well without such quenching, owing to the large model space, the inclusion of strong correlations, and the coupling of the weak interaction to two nucleons through two-body currents.

RESUMEN

The present work delineates redistribution patterns of the hormone-producing cells of the anterior pituitary, after the phase of moulting. Two hundred single comb White Leghorn hens at the end of their first production cycle (Age = 70 week) were purchased from the commercial poultry farm and were induced to moult by high-dietary zinc (3 g/kg feed/day) after 1 week of acclimatization, at the experimental research station, Department of Physiology and Pharmacology, University of Agriculture, Faisalabad. The moulted birds were equally (n = 50) and randomly allocated to their respective groups as G1 (control; CP (Crude protein) 16%, no supplement), G2 (CP18%, no other supplement), G3 (CP16%, symbiotic at does rate of 85 mg/l in drinking water daily) and G4 (CP16%, probiotic at dose rate of 85 mg/l in drinking water daily). Ten birds were slaughtered in each group at 5% and at peak of post-moult production stage to collect their pituitary glands. An earlier post-moult production recovery, sustained and lengthier production span was seen in the G2 as compared to all other groups. The lowest production and an earlier production decline were seen in G1. The cell diameter and area of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) gonadotroph increased (p ≤ 0.01) in G2 and G3 as compared to G1. The FSH gonadotroph nucleus diameter and area did increase (p ≤ 0.01) in G2 and G3, while LH gonadotroph nucleus diameter and area decreased (p ≤ 0.01) in G2 and G3 as compared to G1. The increased FSH and LH gonadotroph diameter in protein and symbiotic supplemented birds is accountable for the increased egg production in these groups.

RESUMEN

BACKGROUND: A primary brain tumor (PBT) is often a fatal disease of the nervous system and has a serious impact on health-related quality of life (HRQOL). Presence of epilepsy and adverse reactions from tumor and epilepsy treatments may cause additional decline in HRQOL. OBJECTIVES: We aimed to study the impact of epileptic seizures on cognition, mood, and HRQOL in patients with brain tumor-related epilepsy. MATERIALS AND METHOD: Patients were grouped on an ordinal scale according to epilepsy burden from none to severe based on the presence of epileptic seizures and seizure frequency: L1, no epilepsy; L2, with epilepsy, seizure-free in the last 6 months with antiepileptic drugs; and L3, with epilepsy, at least one seizure in the last 6 months with AEDs. Health-related quality of life was measured by Functional Assessment of Cancer Therapy-Brain (FACT-Br) and Quality of Life in Epilepsy-31 (QOLIE-31) tools, cognition by the Montreal Cognitive Assessment (MoCA) tool and Frontal Assessment Battery (FAB), mood by the Hospital Anxiety and Depression Scale (HADS), activities of daily living (ADLs) by the Barthel Index (BI), and performance status by the Karnofsky Performance Status (KPS) scale in patients with primary brain tumors at least one month following neurosurgery with or without radiotherapy and chemotherapy. RESULTS: Eighty-one patients with a diagnosis of primary brain tumors were recruited. Sixty-eight percent of patients were diagnosed with primary brain tumor-related epilepsy, 50.61% patients had cognitive impairment, 33% had abnormal scores in the anxiety scale, and 34% had abnormal scores in the depression scale. There were no statistically significant differences in these scores among L1, L2, and L3 groups. There were statistically significant differences in duration of disease and KPS and BI scores between L1 and L3 groups. The L3 group has significantly longer duration of disease and scored low in both the BI and KPS scale when compared to the L1 group. All patients with primary brain tumors scored significantly low in FACT-Br 'physical well-being' (PWB) and 'emotional well-being' (EWB) and high in 'social well-being' (SWB) when compared to healthy controls. When scores of each group were individually compared to healthy controls, the L3 group showed the lowest scores in PWB, EWB, and 'functional well-being'. In SWB, L1 and L2 groups showed statistically significantly high scores when compared to normative data. The QOLIE-31 applied to groups with epilepsy showed statistically significantly lower scores in the L3 group when compared to the L2 group in 'cognitive' and 'social functioning' domains. On multivariate analysis, both poor performance status and frequency of seizures were found to be independent risk factors for poor HRQOL when FACT-Br mean scores were compared. Level of seizures was found to be an independent risk factor for poor HRQOL when QOLIE-31 scores were compared between L2 and L3 groups. DISCUSSION: Presence of brain tumors could be attributed to cognitive impairment irrespective of the presence of epilepsy in our cohort. High seizure burden is an independent risk factor for poor HRQOL in patients with primary brain tumors. The QOLIE-31 is a more sensitive tool than the FACT-Br because of the presence of a seizure-related questionnaire.

RESUMEN

The present study was carried out with the aims to diagnose abdominal masses by FNAC with the help of ultrasonography guidance and to determine the diagnostic accuracy of FNAC. One hundred consecutive patients were studied during the period from January 2005 to December 2005. Histopathological examination was done to correlate with the cytologic diagnosis. The results of comparative study of USG-guided FNAC and histopathology were significant (P value was <0.001). In USG-guided FNAC, it was found that 64 were malignant tumors, 5 were benign tumors, 28 were inflammatory and 3 were inadequate material. Histopathology of 3 inadequate materials showed 1 was adenoma and 2 were leiomyoma. As a whole test results of USG-guided FNAC were sensitivity 95.52%, specificity 100%, positive predictive value 100%, negative predictive value 91.67% and accuracy 97%. USG-guided FNAC has been proved to be a rapid, reliable and cost-effective diagnostic method.

RESUMEN

The quality of information available on health websites in the Gulf Cooperation Council (GCC) countries has not been comprehensively assessed. From November to December 2012 we retrieved all functional health-related websites (n = 925) originating in GCC countries. Data on authorship, language, date, information content and type of site were recorded. A novel website checklist was developed based on the credibility and trust criteria of the Internet assessment organization Health On the Net Foundation (HON). Only 5 sites (0.5%) fulfilled all checklist categories. All websites except one were in English or Arabic languages. Only 10.1% of websites posted a privacy policy, 2.7% stated the authorship of information, 51.0% disclosed website ownership, 80.6% provided contact details and 58.5% dated information. Only 1.7% reported their advertising policy and 23.5% revealed sponsorships. GCC health website owners should consider working with the HON or similar organizations to meet internationally recognized credibility criteria.

RESUMEN

Replacement of commercial chemical preservative (Vinegar) by incorporating fermented bamboo shoot (FBS) products partially or completely and their effect on physicochemical, microbial and shelf life qualities on pork pickle products was studied. Different FBS products such as FBS extract, paste and powder were incorporated in the pork pickle products at the level of 50 to 100 % with or without vinegar and stored at room temperature for 90 days. Highest pH values and lowest titrable acidity was recorded in products with 50 and 100 % FBS powder. No significant differences were observed with respect to proximate composition i.e. percent moisture, protein, fat and ash contents among the products except the product with 100 % FBS powder which had significantly (p < 0.01) lower moisture content. Microbial load (Log total plate counts) and thiobarbituric acid (TBA) values were found to be increasing as the storage periods were advancing. Except the product with 100 % FBS powder which could be stored for 30 days only, other products could be stored upto 90 days without any physicochemical and microbial problems. It can be concluded from this study that natural and organic FBS extract and paste can be used successfully replacing the conventional chemical preservative (Vinegar) for preparation of pork pickle products and preserved more than 90 days at room temperature. However, FBS powder can be used for preservation of the pickle products for a short period (30 days).

RESUMEN

OBJECTIVES: To identify differentially expressed miRNA between oral squamous cell carcinoma (OSCC) and non-cancer (NC) and to associate these with clinico-pathological parameters. MATERIALS AND METHODS: miRNA microarray profiling was utilized to obtain the expression profile of miRNAs in four OSCC and four NC samples. The expression of miR-31 and miR-375 was further validated in 26 OSCC and three NC samples using real-time-PCR. The association between miRNA expression and clinico-pathological parameters was tested by univariate and multivariate analyses. RESULTS: Microarray profiling demonstrated that 15 and four miRNAs were up-regulated and down-regulated, respectively, in OSCC as compared with NC. miR-31 and miR-375 were validated as up- and down-regulated miRNAs, respectively. In univariate analyses, expression of miR-31 was significantly elevated in early stage, tumours with no metastatic nodes and those from the buccal mucosa. By contrast, low miR-375 expression was significantly associated with late stage disease, larger tumour size and the non-cohesive type of pattern of invasion in OSCC. The association between miR-31 expression with tumour staging and site and miR-375 with tumour staging remained significant in multivariate analyses. CONCLUSIONS: This study has identified 19 miRNAs significantly associated with OSCC, and expressions of miR-31 and miR-375 were significantly related with clinico-pathological parameters suggesting they could be important in driving oral tumourigenesis.

RESUMEN

BACKGROUND: The efficacy of adjunctive aripiprazole in patients with major depressive disorder (MDD) with no improvement after 8 weeks of prior antidepressant monotherapy has not been evaluated. METHODS: A post hoc analysis of three similarly designed, randomised, double-blind, placebo-controlled, phase III studies was conducted investigating the efficacy and safety of aripiprazole adjunctive to standard antidepressant treatment (ADT) in MDD patients with a prior inadequate response to one to three ADTs. Minimal improvement to antidepressant monotherapy was defined as a Clinical Global Impressions - Improvement (CGI-I) score of 3 and non-improvement as a CGI-I of 4 at weeks 6 and 8 of antidepressant monotherapy. RESULTS: The end-point response rate for ADT minimal improvers receiving adjunctive aripiprazole was 38.8% vs. 26.6% for adjunctive placebo (p < 0.05; number needed to treat [NNT] = 9 [95% confidence interval: 4.8-27.7]), and for ADT non-improvers receiving adjunctive aripiprazole was 24.0% vs. 10.3% for adjunctive placebo (p < 0.05; NNT = 8 [95% confidence interval: 4.4-21.5]). ADT minimal improvers and non-improvers demonstrated significant improvements in response vs. ADT alone as early as after 1 and 2 weeks of adjunctive treatment, respectively. The end-point remission rate for ADT minimal improvers receiving adjunctive aripiprazole was 34.2% vs. 21.0% for adjunctive placebo (p < 0.05; NNT = 8), and for ADT non-improvers receiving adjunctive aripiprazole was 16.0% vs. 5.9% for adjunctive placebo (p < 0.05; NNT = 10). The most common adverse events for ADT minimal improvers and non-improvers receiving adjunctive aripiprazole were akathisia, restlessness and insomnia. CONCLUSION: Patients with minimal or no improvement after 8 weeks of antidepressant monotherapy significantly benefited from adjunctive aripiprazole treatment, supporting the efficacy of this treatment for MDD patients with all levels of response to ADT.

RESUMEN

This study was planned to investigate the comparative effect of vitamins C (L-ascorbic acid), E (DL-α-tocopherol acetate), probiotics, lower than normal protein level (14%) and combination of these treatments on immune response of male broiler breeders after zinc-induced moulting. One hundred and eighty birds at the age of 65 weeks were induced to moult by mixing zinc oxide (ZnO) in feed at the rate 3000 IU/kg of feed. Upon completion of moulting, birds were divided into six groups (five replicates per group) in a completely randomized design and were fed vitamin C (500 IU/kg), vitamin E (100 IU/kg), lower protein level, probiotics (50 mg/l), and a combination of these components, while one group was kept as control. After completion of moulting phase (5 weeks), the treatment effects were tested as in vitro macrophages engulfment percentage, nitric oxide (NO) production, serum antibody titres against Newcastle disease (ND) and infectious bronchitis (IB). The results showed that in vitro macrophage engulfment percentage in unopsonized conditions was significantly higher in vitamin E-supplemented group. In addition, in opsonized condition, the macrophage engulfment percentage was significantly higher in both vitamin E- and C-supplemented groups. The NO (opsonized and unopsonized) production and antibody titre against ND and IB were significantly higher in vitamin E-supplemented group. It was concluded that vitamin E is a better option for enhanced immune response in broiler breeders after zinc-induced moulting.

RESUMEN

1. A study was designed to investigate the comparative effect of supplementary vitamin E, vitamin C, probiotics and dietary crude protein concentration on semen traits and seminal plasma biochemical parameters in male broiler breeders after Zn-induced moulting. 2. A total of 180 male broiler breeders were induced to moult at 65 weeks of age by mixing ZnO in diet at the rate 3000 mg/kg of feed. After moulting, the males were divided into six groups that were given feed supplemented with: vitamin C (500 IU/kg), vitamin E (100 IU/kg), protein (140 g CP/kg), probiotics (50 mg/kg) and the combination of these components, while one group was kept as a control. Semen samples were collected weekly and semen volume, spermatozoa concentration, motility and dead spermatozoa percentage were determined. Seminal plasma was separated to determine the concentration of total antioxidant capacity (TAC), homocysteine, paraoxonase (PON1), arylesterase, ceruloplasmin, aspartate aminotransferase (AST) and alanine aminotransferase (ALT) activities. 3. Semen volume was significantly higher in the vitamin E and C groups compared to the control. Spermatozoa motility was higher in the vitamin E group and dead spermatozoa percentage was significantly lower in the vitamin C group compared with the control group. 4. Seminal plasma TAC was higher in the vitamin E group, homocysteine was lower in the vitamin C and E groups. PON1 was higher in the combination group. Arylesterase increased significantly in the vitamin C and combination groups over time. Seminal plasma AST was significantly lower in the vitamin C and E supplemented groups whereas ALT decreased significantly only in the vitamin E group compared with the control. Higher concentrations of ceruloplasmin were observed in the combination group compared with the other treatments. 5. It was concluded that additional vitamin E and C or their combination was the most potent nutrient treatment for improving the semen traits and seminal plasma biochemical characteristics in male broiler breeders after Zn-induced moulting.

RESUMEN

BACKGROUND: Multistep pathways and mechanisms are involved in the development of oral cancer. Chromosomal alterations are one of such key mechanisms implicated oral carcinogenesis. Therefore, this study aims to determine the genomic copy number alterations (CNAs) in oral squamous cell carcinoma (OSCC) using array comparative genomic hybridization (aCGH) and in addition attempt to correlate CNAs with modified gene expression. MATERIALS AND METHODS: Genome-wide screening was performed on 15 OSCCs using high-density aCGH. On the basis of pathway analysis, three genes (ISG15, Nestin and WNT11) which mapped to CNA regions were selected for further evaluation of their mRNA expression using quantitative reverse transcriptase PCR (qRT-PCR). RESULTS: Copy number alterations were observed on multiple genomic regions, including amplifications on 1p, 3q, 5p, 6p, 7p, 8q, 9q, 11q, 12q, 16p, 18p and deletions on 3p, 7q, 8p, 11q, 19q and 20q. Among the three selected genes, ISG15 had the highest mRNA expression level with a 22.5-fold increase, followed by Nestin with a 4.5-fold increase and WNT11 with a 2.5-fold increase. CONCLUSIONS: This study has identified several major CNAs in oral cancer genomes and indicated that this correlates with over expression of the ISG15, WNT11, and Nestin genes.

RESUMEN

Dietary zinc was used to induce molt in 200 White Leghorn birds in caged housing at the age of 70 wk. The birds were equally and randomly allocated to 4 groups each of 50 birds as G1 (control; CP 16%, no supplement), G2 (CP 18%, no other supplement), G3 (CP 16%, symbiotic Perfectin: 85 mg•L(-1) in drinking water daily), and G4 (CP 16%, probiotic Protexin: 85 mg•L(-1) in drinking water daily) after the completion of molt. The sampling was conducted 3 times at 5% production, peak production, and end of production with 15 birds being killed at each sampling from each group to collect the blood for harvesting of serum. Serum health markers including total oxidant status, total antioxidant capacity, homocysteine concentration, and paraoxonase, arylesterase, and ceruloplasmin activity were determined by the prescribed assays. The overall total antioxidant capacity was increased, whereas total oxidant status and homocysteine concentrations were reduced significantly (P ≤ 0.01) in all the supplemented groups compared with the control. The paraoxonase and ceruloplasmin activity were enhanced (P ≤ 0.01) in the supplemented groups compared with the control, and arylesterase activity was increased (P ≤ 0.01) in only G2 compared with the other groups. Although protein supplementation significantly reduced the oxidative stress, supplementation with symbiotic and probiotic also improved the health status by decreasing the oxidative stress in the birds.

RESUMEN

Conventional open heart surgery with cardiopulmonary bypass (CPB) are associated with transient post-operative renal dysfunction which is caused by systemic inflammatory response induced by CPB. Corticosteroids are administered to attenuate the systemic inflammatory response. The purpose of this study was to compare the effects of pre-bypass and post-bypass methylprednisolone on postoperative renal function after correction of ASD under CPB. Forty (40) patients were selected in the University cardiac centre of BSMMU undergoing ASD correction under CPB. Patients were randomized into two group to receive pre-bypass (Group A) or post-bypass (Group B) methylprednisolone 30mg/kg. Markers of glomerular function (BUN, serum creatinine, creatinine clearance) and damage (micro-albuminuria) and tubular function (glucosuria) were evaluated 24 hours after operation. Transient impairment of glomerular and tubular function of kidney was observed in patients those received post-bypass metylprednisolone (Group B) while Group A patients shown no significant difference between baseline and post-operative renal function. Use of pre-bypass methylprednisolone has a protective effect on post-operative renal function after correction of ASD under CPB.

RESUMEN

Opioids are widely prescribed for pain management, and prescription opioid misuse in adolescents has become a major epidemic in the United States and worldwide. Emerging data indicate that adolescence represents a critical period of brain development, and exposure to opioids during adolescence may increase the risk of addiction in adulthood. There is growing evidence that disruptions in brain glial function may be implicated in numerous chronic neuropathologies. Evidence suggests that glial mechanisms have an important role in the development and maintenance of opioid abuse and the risk for addiction. This review will describe glial and neuroimmune mechanisms involved in opioid use disorders during adolescence, which may increase substance use disorder liability later in life. Moreover, this review will identify some important neuro-glial targets, involved in opioid abuse and addiction, to develop future preventions and treatment strategies.

RESUMEN

A multiwavelength widely tunable Brillouin optical comb with an enhanced reverse-S-shaped feedback coupling assisted by out-of-cavity optical amplifier is demonstrated. The enhancement is done by locating the amplifier and the Brillouin pump into the reverse-S-shaped fiber section. The oscillating modes in the cavity are directly influenced solely by the Brillouin gain. A wide tuning range of 45 nm is obtained that is only limited by the erbium amplification bandwidth. An average of eleven laser lines that can be tuned to over 45 nm wavelengths is obtained at 40% optimum output coupling ratio.

RESUMEN

This study was intended to explore the oxidative status of broilers under cyclic heat stress (HS) as modulated by supplementation of mannan-oligosaccharides (MOS) and a probiotic mixture (PM). Two hundred fifty 1-d-old chicks were randomly divided into 5 groups. From d 22, birds were either kept in a thermoneutral zone (TN; 26.7°C for 24 h/d) or subjected to HS (35 ± 1.1°C and 75 ± 5% RH for 8 h/d from 1000 to 1800 h) to the conclusion of the study on d 42. Birds were fed either a corn-based diet (TN and HS groups) or the same diet supplemented with 0.5% MOS (HS-MOS group), 0.1% PM (HS-PM group), or their combination as a symbiotic (SYN; HS-SYN group). On d 42, birds were killed by cervical dislocation to collect serum for the determination of total oxidants, total antioxidants, paraoxonase, arylesterase, ceruloplasmin, aspartate aminotransferase, alanine aminotransferase, and trace minerals. Heat stress increased (P < 0.05) total oxidants and total antioxidants and decreased (P < 0.05) paraoxonase and arylesterase, with no change in ceruloplasmin, aspartate aminotransferase, and alanine aminotransferase activities. Dietary supplementation decreased (P < 0.05) total oxidants and total antioxidants, with no effect on the activities of other enzymes. Heat stress did not influence serum copper, zinc, and manganese concentrations of birds when compared with those in the TN group. However, MOS increased (P < 0.05) concentrations of all the trace minerals, whereas SYN increased (P < 0.05) concentrations of only zinc and copper. It was concluded that MOS or PM supplementation, alone or as a SYN, may reduce some of the detrimental effects of HS, whereas MOS alone or as a SYN may improve the absorption of trace minerals.

RESUMEN

Percutaneous coronary intervention (PCI) is a catheter based procedure where a catheter system is introduced through a systemic artery under local anesthesia in a stenotic coronary artery by controlled inflation of a distensible balloon. At early period, PCI was done in a separate session following coronary angiogram (Staged PCI) and it was more costly and hospital stay was long. As the expertization and laboratory facilities improved, the health care providers think about cost, hospital stay and patient convenience. So, to reduce the cost and patient preferred more PCI being done immediately following diagnostic catheterization (Ad-hoc PCI). Subsequently this Ad-hoc procedure becomes popular and now most of the PCI are Ad-hoc PCI worldwide. Rate of combined procedure (Ad-hoc) progressively increased from 54% in 1990 to 88% in 2000 with a significant decrease in rate of complications. In the initial study of Ad-hoc PCI suggested that Ad-hoc PCI should be done in selected group of patients as there was some potential risk factors (e.g. Multivessel diseases, unstable angina, aortic valve disease, and recent infarction or thrombolytic therapy) for Ad-hoc procedure and some (e.g. Older age, multivessel PTCA and complex lesion PTCA) for staged procedure. But recent studies showed that no significant difference in respect of safety and efficacy between Ad-hoc and staged PCI. Previous studies, in the era of balloon angioplasty from 1985 to 1995, Haraphonges et al. (1988), Rozenman et al. (1995) and Kimmel et al. (1997) suggested that an ad hoc approach is safe, with potentially more complications in patients with unstable angina pectoris or other high-risk factors. However, these reports have been limited to observational studies representing single institution experiences with small samples and inclusion of patients who underwent emergency PCI procedures. In Bangladesh a prospective observational study was done among 120 patients to compare the outcome of Ad-hoc and staged PCI and high angiographic, procedural and clinical success rate with minimum complications were observed in Ad-hoc PCI in comparison to Staged PCI.

RESUMEN

Defects in hemostasis are frequently seen in open heart surgery. Strategies should be reviewed about the peri-operative blood loss and conservation of blood here. In this study, comparison among three agents (Aprotinin, Tranaexaemic Acid & Epsilon Amino Caproic Acid) is done to reduce the peri-operative blood loss in open-heart surgery. Ninety male and female patients within 20-60 years of age were selected who underwent conventional cardiac surgery and anesthesia with Cardio-pulmonary-bypass for common open heart surgeries (ASD, VSD, AVR, etc) and randomly divided into three groups 30 patients in each. Group A, B, C was administered Inj. Aprotinin, Tranaexaemic acid & EACA respectively. Perioperative hemodynamic parameters and blood loss in suction bottle & drainage tube were noted until the 3rd POD. Requirement of blood transfusion, heparin, protamine and blood derived products were also noted. Activated clotting time was documented in the perioperative period. Clinically relevant outcome like re-exploration, mechanical ventilation, morbidities, mortality etc were also verified. Data were analyzed and results were calculated with student's T test & ANOVA. The groups were matched regarding recorded peri-operative variables. Peri-operative blood loss is significantly reduced (p<0.05) both in the Aprotinin and Tranexamic acid groups. Renal dysfunction was reported in 20% of aprotinin patients, 14.29% of tranexaemic acid patients and 18.51% of EACA patients. A conclusion was drawn from the study that Tranexamic acid can significantly reduce the peri-operative blood loss in open heart surgery cases and that it can be preferred as an agent of choice in blood conservation strategy in these cases.

RESUMEN

Arthrocentesis and arthroscopy are relatively safe treatments for arthrogenic temporomandibular disorders. Hands-on training in both procedures is essential for surgeons to become competent. In this study, a three-dimensional (3D) temporomandibular joint (TMJ) prototype was developed at a relatively low cost, and arthrocentesis and arthroscopy were performed successfully on the model. Despite its limitations, this model is a viable adjunct to TMJ surgical training and can be fabricated easily by any training centre with a 3D printer.
