Pemberdayaan Masyarakat Melalui Program Inovasi Desa (PID) di Desa Lipu Kecamatan Kadatua Kabupaten Buton Selatan
Desa dengan keidentikanya akan keterbelakangan serta penumpukan angkatan kerja produktif yang menganggur. Salah satu upaya yang dilakukan untuk mengatasi masalah tersebut adalah dengan menghadirkan program inovasi desa (PID). Secara teoritis hadirnya PID merupakan upaya dalam menuntaskan problem ketimpangan serta kemiskinan khususnya di Desa. Penelitian ini secara spesifik ingin melihat sejauh mana implementasi serta angka keberhasilan program PID di Desa Lipu. Metode yang digunakan adalah pendekatan kualitatif deskriptif yaitu dengan mendiskripsikan fakta-fakta serta hubungan antara fenomena yang diteliti, termasuk hubungan kegiatan, sikap, pandangan serta proses yang sedang dilakukan dan pengaruh dari fenomena untuk menentukan hubungan tertentu antara suatu gejala dengan gejala lain. Hasil dari penelitian ini menunjukan bahwa Pemberdayaan Masyarakat Melalui Program Inovasi Desa (PID) di Desa Lipu Kecamatan Kadatua Kabupaten Buton Selatan belum dilakukan dengan maksimal, yakni kualitas dan kuantitas masyarakat partisipasi masyarakat yang mulai menurun, baik dari mengikuti kegiatan langsung maupun dalam pengambilan keputusan
Pemberian Minyak Sereh Terhadap Transportasi Benih Ikan Patin (Pangasius sp.) Berkepadatan Tinggi
Transportasi ikan merupakan salah satu penunjang kegiatan produksi dalam bidang perikanan. Faktor pembatas transportasi adalah adanya jarak waktu yang cukup jauh antara usaha pembenihan ikan dengan usaha kegiatan pendederan dan pembesaran sehingga menimbulkan peningkatan metabolisme tubuh ikan yang mengakibatkan tingginya mortalitas/kematian ikan selama transportasi. Minyak sereh memiliki zat aktif yang mampu menurunkan metabolisme di dalam tubuh ikan sehingga tubuh ikan menjadi lebih tenang. Tujuan penelitian transportasi ini adalah menganalisa pemberian minyak sereh dosis berbeda dengan penambahan garam, karbon aktif dan zeolit guna meningkatkan kelangsungan hidup benih ikan patin. Metode yang digunakan adalah Rancangan Acak Lengkap yang terdiri dari lima perlakuan dan tiga ulangan yaitu: Perlakuan K: Tanpa dosis minyak sereh, garam, karbon aktif dan zeolit; Perlakuan A: Minyak sereh dosis 0 mg/L, garam dosis 6 g/L, karbon aktif dosis 10 g, dan zeolit dosis 20 g; Perlakuan B: Minyak sereh dosis 3,5 mg/L, garam dosis 6 g/L, karbon aktif dosis 10 g, dan zeolit dosis 20 g; Perlakuan C: Minyak sereh dosis 7 mg/L, garam dosis 6 g/L, karbon aktif dosis 10 g, dan zeolit dosis 20 g; Perlakuan D: Minyak sereh dosis 10,5 mg/L, garam dosis 6 g/L, karbon aktif dosis 10 g, dan zeolit dosis 20 g. Hasil penelitian menunjukkan bahwa perlakuan minyak sereh dosis 7 mg/L, garam dosis 6 g/L, karbon aktif dosis 10 g, dan zeolit dosis 20 g memperoleh tingkat kelangsungan hidup benih ikan patin sebesar 86,67±1,33 %.Keywords: benih ikan patin, minyak sereh, tingkat kelangsungan hidup, transportasi tertutu
Echocardiographic evaluation of mitral geometry in functional mitral regurgitation
<p>Abstract</p> <p>Objectives</p> <p>We sought to evaluate the geometric changes of the mitral leaflets, local and global LV remodeling in patients with left ventricular dysfunction and varying degrees of Functional mitral regurgitation (FMR).</p> <p>Background</p> <p>Functional mitral regurgitation (FMR) occurs as a consequence of systolic left ventricular (LV) dysfunction caused by ischemic or nonischemic cardiomyopathy. Mitral valve repair in ischemic MR is one of the most controversial topic in surgery and proper repairing requires an understanding of its mechanisms, as the exact mechanism of FMR are not well defined.</p> <p>Methods</p> <p>136 consecutive patients mean age of 55 with systolic LV dysfunction and FMR underwent complete echocardiography and after assessing MR severity, LV volumes, Ejection Fraction, LV sphericity index, C-Septal distance, Mitral valve annulus, Interpapillary distance, Tenting distance and Tenting area were obtained.</p> <p>Results</p> <p>There was significant association between MR severity and echocardiogarphic indices (all p values < 0.001). Severe MR occurred more frequently in dilated cardiomyopathy (DCM) patients compared to ischemic patients, (p < 0.001). Based on the model, only Mitral valve tenting distance (TnD) (OR = 22.11, CI 95%: 14.18 – 36.86, p < 0.001) and Interpapillary muscle distance (IPMD), (OR = 6.53, CI 95%: 2.10 – 10.23, p = 0.001) had significant associations with MR severity.</p> <p>Mitral annular dimensions and area, C-septal distance and sphericity index, although greater in patients with severe regurgitation, did not significantly contribute to FMR severity.</p> <p>Conclusion</p> <p>Degree of LV enlargement and dysfunction were not primary determinants of FMR severity, therefore local LV remodeling and mitral valve apparatus deformation are the strongest predictors of functional MR severity.</p
Strongly magnetized pulsars: explosive events and evolution
Well before the radio discovery of pulsars offered the first observational
confirmation for their existence (Hewish et al., 1968), it had been suggested
that neutron stars might be endowed with very strong magnetic fields of
-G (Hoyle et al., 1964; Pacini, 1967). It is because of their
magnetic fields that these otherwise small ed inert, cooling dead stars emit
radio pulses and shine in various part of the electromagnetic spectrum. But the
presence of a strong magnetic field has more subtle and sometimes dramatic
consequences: In the last decades of observations indeed, evidence mounted that
it is likely the magnetic field that makes of an isolated neutron star what it
is among the different observational manifestations in which they come. The
contribution of the magnetic field to the energy budget of the neutron star can
be comparable or even exceed the available kinetic energy. The most magnetised
neutron stars in particular, the magnetars, exhibit an amazing assortment of
explosive events, underlining the importance of their magnetic field in their
lives. In this chapter we review the recent observational and theoretical
achievements, which not only confirmed the importance of the magnetic field in
the evolution of neutron stars, but also provide a promising unification scheme
for the different observational manifestations in which they appear. We focus
on the role of their magnetic field as an energy source behind their persistent
emission, but also its critical role in explosive events.Comment: Review commissioned for publication in the White Book of

P2 receptors are involved in the mediation of motivation-related behavior
The importance of purinergic signaling in the intact mesolimbic–mesocortical circuit of the brain of freely moving rats is reviewed. In the rat, an endogenous ADP/ATPergic tone reinforces the release of dopamine from the axon terminals in the nucleus accumbens as well as from the somatodendritic region of these neurons in the ventral tegmental area, as well as the release of glutamate, probably via P2Y1 receptor stimulation. Similar mechanisms may regulate the release of glutamate in both areas of the brain. Dopamine and glutamate determine in concert the activity of the accumbal GABAergic, medium-size spiny neurons thought to act as an interface between the limbic cortex and the extrapyramidal motor system. These neurons project to the pallidal and mesencephalic areas, thereby mediating the behavioral reaction of the animal in response to a motivation-related stimulus. There is evidence that extracellular ADP/ATP promotes goal-directed behavior, e.g., intention and feeding, via dopamine, probably via P2Y1 receptor stimulation. Accumbal P2 receptor-mediated glutamatergic mechanisms seem to counteract the dopaminergic effects on behavior. Furthermore, adaptive changes of motivation-related behavior, e.g., by chronic succession of starvation and feeding or by repeated amphetamine administration, are accompanied by changes in the expression of the P2Y1 receptor, thought to modulate the sensitivity of the animal to respond to certain stimuli
Quantum Spacetime Phenomenology
I review the current status of phenomenological programs inspired by
quantum-spacetime research. I stress in particular the significance of results
establishing that certain data analyses provide sensitivity to effects
introduced genuinely at the Planck scale. And my main focus is on
phenomenological programs that managed to affect the directions taken by
studies of quantum-spacetime theories.Comment: 125 pages, LaTex. This V2 is updated and more detailed than the V1,
particularly for quantum-spacetime phenomenology. The main text of this V2 is
about 25% more than the main text of the V1. Reference list roughly double

BACH2 immunodeficiency illustrates an association between super-enhancers and haploinsufficiency.
The transcriptional programs that guide lymphocyte differentiation depend on the precise expression and timing of transcription factors (TFs). The TF BACH2 is essential for T and B lymphocytes and is associated with an archetypal super-enhancer (SE). Single-nucleotide variants in the BACH2 locus are associated with several autoimmune diseases, but BACH2 mutations that cause Mendelian monogenic primary immunodeficiency have not previously been identified. Here we describe a syndrome of BACH2-related immunodeficiency and autoimmunity (BRIDA) that results from BACH2 haploinsufficiency. Affected subjects had lymphocyte-maturation defects that caused immunoglobulin deficiency and intestinal inflammation. The mutations disrupted protein stability by interfering with homodimerization or by causing aggregation. We observed analogous lymphocyte defects in Bach2-heterozygous mice. More generally, we observed that genes that cause monogenic haploinsufficient diseases were substantially enriched for TFs and SE architecture. These findings reveal a previously unrecognized feature of SE architecture in Mendelian diseases of immunity: heterozygous mutations in SE-regulated genes identified by whole-exome/genome sequencing may have greater significance than previously recognized
Physical Exercise Training versus Relaxation in Allogeneic stem cell transplantation (PETRA Study) – Rationale and design of a randomized trial to evaluate a yearlong exercise intervention on overall survival and side-effects after allogeneic stem cell transplantation
Global variation in anastomosis and end colostomy formation following left-sided colorectal resection
Background
End colostomy rates following colorectal resection vary across institutions in high-income settings, being influenced by patient, disease, surgeon and system factors. This study aimed to assess global variation in end colostomy rates after left-sided colorectal resection.
Methods
This study comprised an analysis of GlobalSurg-1 and -2 international, prospective, observational cohort studies (2014, 2016), including consecutive adult patients undergoing elective or emergency left-sided colorectal resection within discrete 2-week windows. Countries were grouped into high-, middle- and low-income tertiles according to the United Nations Human Development Index (HDI). Factors associated with colostomy formation versus primary anastomosis were explored using a multilevel, multivariable logistic regression model.
Results
In total, 1635 patients from 242 hospitals in 57 countries undergoing left-sided colorectal resection were included: 113 (6·9 per cent) from low-HDI, 254 (15·5 per cent) from middle-HDI and 1268 (77·6 per cent) from high-HDI countries. There was a higher proportion of patients with perforated disease (57·5, 40·9 and 35·4 per cent; P < 0·001) and subsequent use of end colostomy (52·2, 24·8 and 18·9 per cent; P < 0·001) in low- compared with middle- and high-HDI settings. The association with colostomy use in low-HDI settings persisted (odds ratio (OR) 3·20, 95 per cent c.i. 1·35 to 7·57; P = 0·008) after risk adjustment for malignant disease (OR 2·34, 1·65 to 3·32; P < 0·001), emergency surgery (OR 4·08, 2·73 to 6·10; P < 0·001), time to operation at least 48 h (OR 1·99, 1·28 to 3·09; P = 0·002) and disease perforation (OR 4·00, 2·81 to 5·69; P < 0·001).
Conclusion
Global differences existed in the proportion of patients receiving end stomas after left-sided colorectal resection based on income, which went beyond case mix alone
