Studies on two polyherbal formulations (ZPTO and ZTO) for comparison of their antidyslipidemic, antihypertensive and endothelial modulating activities
Background
Cardiovascular disorders (CVDs) are the leading cause of disease burden worldwide. Apart from available synthetic drugs used in CVDs, there are many herbal formulations including POL-10 (containing 10 herbs), which have been shown to be effective in animal studies but POL-10 was found to cause tachycardia in rodents as its side effect. This study was designed to modify the composition of POL-10 for better efficacy and/or safety profile in CVDs. Methods
To assess the antidyslipidemic, antihypertensive and endothelial modulatory properties of two herbal formulations, (ZPTO and ZTO) containing Z: Zingiber officinalis, P: Piper nigrum, T: Terminalia belerica and O: Orchis mascula, different animal models including, tyloxapol and high fat diet-induced dyslipidemia and spontaneously hypertensive rats (SHR) were used. Effect on endothelial function was studied using isolated tissue bath set up coupled with PowerLab data acquisition system. The antioxidant activity was carried out using DPPH radical-scavenging assay. Results
Based on preliminary screening of the ingredients of POL-10 in tyloxapol-induced hyperlipidemic rats, ZPTO and ZTO containing four active ingredients namely; Z, P, T and O were identified for further studies and comparison. In tyloxapol-induced hyperlipidemic rats, both ZPTO and ZTO caused significant reduction in serum triglyceride (TG) and total cholesterol (TC). In high fat diet-fed rats, ZPTO decreased TC, low-density lipoproteins cholesterol (LDL-C) and atherogenic index (AI). ZTO also showed similar effects to those of ZPTO with additional merits being more effective in reducing AI, body weight and more importantly raising high-density lipoproteins. In SHR, both formulations markedly reduced systolic blood pressure, AI and TG levels, ZTO being more potent in reversing endothelial dysfunction while was devoid of cardiac stimulatory effect. In addition, ZTO also reduced LDL-C and improved glucose levels in SHR. In DPPH radical-scavenging activity test, ZTO was also more potent than ZPTO. Conclusion
The modified formulation, ZTO was not only found more effective in correcting cardiovascular abnormalities than ZPTO or POL-10 but also it was free from tachycardiac side-effect, which might be observed because of the presence of Piper nigrum in ZPTO
Search for Charged Higgs Bosons in e+e- Collisions at \sqrt{s} = 189 GeV
A search for pair-produced charged Higgs bosons is performed with the L3
detector at LEP using data collected at a centre-of-mass energy of 188.6 GeV,
corresponding to an integrated luminosity of 176.4 pb^-1. Higgs decays into a
charm and a strange quark or into a tau lepton and its associated neutrino are
considered. The observed events are consistent with the expectations from
Standard Model background processes. A lower limit of 65.5 GeV on the charged
Higgs mass is derived at 95 % confidence level, independent of the decay
branching ratio Br(H^{+/-} -> tau nu)
Aspek Agronomi Pohon Karet dan Masalah yang Dihadapi Petani Karet
Tebal kulit disadap, kedalaman sadap, panjang alur sadap, frekuensi sadap, dan waktu sadap harus dipertimbangkan dalam penyadapan pohon karet. Perencanaan penggunaan bidang sadap penting untuk menjamin periode sadap yang panjang, lebih dari 25 tahun. Pada perkebunan karet rakyat hal tersebut tidak dianut. Oleh karena itu, penyuluhan yang sesuai dengan kebutuhan petani diperlukan. Penelitian ini menyajikan aspek agronomi perkebunan karet rakyat yang menunjukkan rendahnya produksi dan beberapa aspek penyuluhan yang diperlukan petani karet. Penelitian dilakukan melalui survei dan tanya jawab pada Juni-Juli 2019 di Desa Sari Laba Jahe, Kecamatan Biru-Biru, Kabupaten Deli Serdang, Provinsi Sumatera Utara. Kelompok yang disurvei adalah Kelompok Tani Mekar Tani yang beranggota 30 orang. Pengumpulan data dilakukan dengan pengamatan kebun karet masing-masing petani dan tanya jawab untuk memperoleh data serta informasi, berkaitan dengan aspek agronomi. Hasil penelitian menunjukkan bahwa petani karet belum menghasilkan produksi ideal, 26,67% petani menghasilkan kurang dari 25 g per pohon per sadap. Sebanyak 17 petani mengelola kebun seluas kurang dari 1 ha dan 1-1,5 ha mengelola kurang dari 500 pohon per ha. Sebanyak 46% petani berpendapat bahwa masalah yang dihadapi dalam mengelola kebun karetnya adalah penyakit jamur akar putih (JAP)
Performance of the CMS Cathode Strip Chambers with Cosmic Rays
The Cathode Strip Chambers (CSCs) constitute the primary muon tracking device
in the CMS endcaps. Their performance has been evaluated using data taken
during a cosmic ray run in fall 2008. Measured noise levels are low, with the
number of noisy channels well below 1%. Coordinate resolution was measured for
all types of chambers, and fall in the range 47 microns to 243 microns. The
efficiencies for local charged track triggers, for hit and for segments
reconstruction were measured, and are above 99%. The timing resolution per
layer is approximately 5 ns
2019 international consensus on cardiopulmonary resuscitation and emergency cardiovascular care science with treatment recommendations : summary from the basic life support; advanced life support; pediatric life support; neonatal life support; education, implementation, and teams; and first aid task forces
The International Liaison Committee on Resuscitation has initiated a continuous review of new, peer-reviewed, published cardiopulmonary resuscitation science. This is the third annual summary of the International Liaison Committee on Resuscitation International Consensus on Cardiopulmonary Resuscitation and Emergency Cardiovascular Care Science With Treatment Recommendations. It addresses the most recent published resuscitation evidence reviewed by International Liaison Committee on Resuscitation Task Force science experts. This summary addresses the role of cardiac arrest centers and dispatcher-assisted cardiopulmonary resuscitation, the role of extracorporeal cardiopulmonary resuscitation in adults and children, vasopressors in adults, advanced airway interventions in adults and children, targeted temperature management in children after cardiac arrest, initial oxygen concentration during resuscitation of newborns, and interventions for presyncope by first aid providers. Members from 6 International Liaison Committee on Resuscitation task forces have assessed, discussed, and debated the certainty of the evidence on the basis of the Grading of Recommendations, Assessment, Development, and Evaluation criteria, and their statements include consensus treatment recommendations. Insights into the deliberations of the task forces are provided in the Justification and Evidence to Decision Framework Highlights sections. The task forces also listed priority knowledge gaps for further research
Performance of CMS muon reconstruction in pp collision events at sqrt(s) = 7 TeV
The performance of muon reconstruction, identification, and triggering in CMS
has been studied using 40 inverse picobarns of data collected in pp collisions
at sqrt(s) = 7 TeV at the LHC in 2010. A few benchmark sets of selection
criteria covering a wide range of physics analysis needs have been examined.
For all considered selections, the efficiency to reconstruct and identify a
muon with a transverse momentum pT larger than a few GeV is above 95% over the
whole region of pseudorapidity covered by the CMS muon system, abs(eta) < 2.4,
while the probability to misidentify a hadron as a muon is well below 1%. The
efficiency to trigger on single muons with pT above a few GeV is higher than
90% over the full eta range, and typically substantially better. The overall
momentum scale is measured to a precision of 0.2% with muons from Z decays. The
transverse momentum resolution varies from 1% to 6% depending on pseudorapidity
for muons with pT below 100 GeV and, using cosmic rays, it is shown to be
better than 10% in the central region up to pT = 1 TeV. Observed distributions
of all quantities are well reproduced by the Monte Carlo simulation.Comment: Replaced with published version. Added journal reference and DO

Comparative study on the diversity performance between different microstrip antenna arrays
Institution of Engineering and Technology. All rights reserved. In this paper, a unique systematic comparative study between different microstrip antennas array types is presented. The study includes a comparison based on the mutual coupling (S 21 ) and the envelope correlation coefficient between four different antennas array types: (a) PIFA antenna, (b) patch antenna, (c) monopole antenna, (d) slot antenna. All these different microstrip antennas have been designed and printed on a thin 1.6 mm FR-4 substrate with dielectric constant (ѓ r = 4.4), suitable for wireless PCS applications (1.9 GHz). Numerical simulations are carried out using HFSS ver 17.0 software. The mutual coupling and envelope correlation coefficient between these different microstrip antennas are studied for various antenna separations. Also, another brief comparison is presented which based on the obtained results particularly in inputs return and radiation characteristics loss at fixed antenna separation, by determining the primarily associated parameters such as the bandwidth, gain, directivity, radiation efficiency. However; it is found that separation between multiple antenna elements is the most critical and crucial parameter affecting on the antenna diversity performance such as both the mutual coupling and the envelope correlation coefficient (primarily it will decrease linearly with the distance increment). This comparative study would be very helpful for RF design engineers to select suitable microstrip antenna type while designing antenna arrays at frequency 1.9 GHz for wireless PCS applications
