Penyakit kuning pada kacang panjang berdampak pada penurunan produksi. Gejala serangan diawali dari gejala daun keriting serta mengakibatkan polong berwarna kuning. Penelitian ini bertujuan mengetahui nilai heritabilitas dan ragam genetik serta menduga jumlah gen pengendali ketahanan kacang panjang terhadap penyakit kuning. Penelitian dilaksanakan di Kabupaten Kediri pada bulan April sampai Juli 2013. Bahan penelitian adalah populasi UB 715 A (P1), Hitam Putih (P2), populasi F1 dan populasi F2. Berdasarkan hasil penelitian, populasi UB 715 A (P1 ) menunjukkan respon tahan terhadap penyakit kuning, populasi Hitam Putih (P2) menunjukkan respon rentan, dan populasi F1 dan F2 menunjukkan respon sedang. Karakter jumlah polong dan jumlah biji per tanaman memiliki keragaman yang sempit sedangkan karakter panjang polong, bobot segar polong, umur berbunga, dan umur panen memiliki keragaman yang luas. Karakter panjang polong dan jumlah biji per polong memiliki nilai heritabilitas rendah, sedangkan karakter jumlah polong, bobot segar polong, umur berbunga, dan umur panen memiliki nilai heritabilitas tinggi. Rasio sifat ketahanan terhadap penyakit kuning pada populasi F2 adalah 9 tahan : 3 sedang : 4 rentan yang berarti ketahanan terhadap penyakit kuning dikendalikan oleh dua gen dengan aksi gen epistasis resesif
Syntheses, crystal structures, and photoluminescence of two Cd(II) complexes with simple ligands
<div><p>Two cadmium complexes, {[Cd<sub>2</sub>(2,5-tda)<sub>2</sub>(ip)<sub>4</sub>]·4H<sub>2</sub>O}<sub><i>n</i></sub> (<b>1</b>) and {[Cd<sub>2</sub>(4,4′-obb)<sub>2</sub>(ip)<sub>2</sub>·H<sub>2</sub>O]·H<sub>2</sub>O}<sub><i>n</i></sub> (<b>2</b>) (2,5-tda = thiophene-2,5-dicarboxylic acid, 4,4′-obb = 4,4′-oxybisbenzoic acid, ip = 1H-imidazo[4,5-f][1, 10]-phenanthroline), were synthesized and characterized by IR, elemental analysis, powder X-ray diffraction, and single-crystal X-ray diffraction. X-ray analysis revealed that <b>1</b> is a dinuclear complex with the 2,5-tda anion connecting two Cd ions in a <i>μ</i><sub>1</sub>-<i>η</i><sup>1</sup>:<i>η</i><sup>0</sup>/<i>μ</i><sub>1</sub>-<i>η</i><sup>1</sup>:<i>η</i><sup>0</sup> coordination mode. Each dinuclear complex is further connected with neighboring complexes via hydrogen-bonding interactions. Compound <b>2</b> displays a 2-D layer structure with opened windows occupied by crystallographic water molecules. The layers are further packed via hydrogen-bonding interactions. Luminescent properties for <b>1</b> and <b>2</b> are also investigated in the solid state at room temperature.</p></div
The relationship between breast cancer incidence, mammography and income in New York State
During the first decade of the 2000s, film mammography was almost wholly replaced by digital technology. Digital mammography was introduced unevenly, with early adopters tending to be located in wealthier communities. Since digital mammography is more sensitive than film mammography, the disparity in technology could have contributed to disparities in breast cancer incidence rates. For in situ breast cancer, we estimate the differences in technology could have contributed to a 13% difference in incidence between the wealthiest and poorest women. Since the observed difference was over 100%, the contribution of differing mammography technologies was likely small
Recalibrating the NAACCR Hispanic Identification Algorithm (NHIA)
Central cancer registries in the United States used a birthplace and surname algorithm to improve the identification of Hispanic patients. This poster describes the implications of switching from a sample-based surname list developed in the 1990s to a population-based surname list derived from the 2010 census. We found that it will have a negligible impact on Hispanic cancer rates
Enhanced identification of out-of-state cases by utilizing "text - place of diagnosis"
<p>One of the primary functions of a state cancer registry is to determine statewide cancer rates. These can be slightly inflated when patients from other states or countries are erroneously counted in the total. Some of these patients can be identified by inspecting the ‘TEXT – PLACE OF DIAGNOSIS’ field in the submitted records. We flagged cases for review by looking for names and distinctive abbreviations of other states, major cities, and countries appearing in this field. 76% of the cases reviewed were determined to reside outside of the state, enough to reduce overall crude rates for 2012 by about 0.4%. The labor-intensive nature of this process means that it might not be practical for registries to review all of their historical data in this manner, but it might be possible for them to keep pace going forward.</p>

What factors influence hospitalizations among dying cancer patients? An analysis of aggressive end-of-life cancer care
<p>Aggressive end-of-life (EOL) care is usually considered to be of poor quality and little value, but cancer patients often make avoidable and distressing hospital visits shortly before death. Cancer patients’ quality of life has been more extensively studied than the quality of dying, which has only recently begun to garner attention in the research community. This exploratory study aimed to identify predictors of aggressive EOL cancer care, with the hope of revealing targets for deeper analysis. The results suggest that racial and ethnic minority status, greater neighborhood poverty, earlier stage at diagnosis, and presence of comorbidity increase the likelihood of receiving aggressive EOL care among dying cancer patients.</p
Resolving conflicting race information from multiple sources
<p>Race is an important demographic variable in cancer statistics. The determination of an accurate race is difficult when a patient has conflicting race data from different reporting sources. In the New York State Cancer Registry, 11.6% of cases diagnosed between 1995-2008 had conflicting race information from different sources. Here we report on a new algorithm to aid in resolving these conflicts.</p>

Porous Perovskite La<sub>0.6</sub>Sr<sub>0.4</sub>Co<sub>0.8</sub>Mn<sub>0.2</sub>O<sub>3</sub> Nanofibers Loaded with RuO<sub>2</sub> Nanosheets as an Efficient and Durable Bifunctional Catalyst for Rechargeable Li–O<sub>2</sub> Batteries
The
design and synthesis of efficient electrocatalysts are important
for electrochemical energy conversion and storage technologies. Poor
electrocatalytic activities of the cathode catalysts toward both the
oxygen reduction reaction (ORR) and oxygen evolution reaction (OER)
are still two major challenges facing Li–O<sub>2</sub> batteries.
Here, we report ultralong porous perovskite La<sub>0.6</sub>Sr<sub>0.4</sub>Co<sub>0.8</sub>Mn<sub>0.2</sub>O<sub>3</sub> nanofibers
(LSCM NFs) loaded with RuO<sub>2</sub> nanosheets (RuO<sub>2</sub>@LSCM NFs) used as a promising catalyst for Li–O<sub>2</sub> batteries. The LSCM nanofibers were synthesized via an electrospinning
technique followed by heat treatment. RuO<sub>2</sub> nanosheets were
loaded by a wet impregnation method. In comparison with that of the
pristine LSCM NFs, the cell with RuO<sub>2</sub>@LSCM NFs catalyst
exhibits good performances toward the ORR and OER with a higher specific
discharge capacity (12741.7 mA h g<sup>–1</sup>), improved
cyclability, and rate capability as well as low voltage gap. Moreover,
the results of LSV indicate that LSCM NFs can efficiently catalyze
the decomposition of the reaction side product Li<sub>2</sub>CO<sub>3</sub> while RuO<sub>2</sub>@LSCM NFs are capable of decomposing
LiOH. The enhanced cell performances are attributed to the merits
of high catalytic activity and the porous structure of the RuO<sub>2</sub>@LSCM NF catalyst
Tuning Structural Topologies of Three Photoluminescent Metal–Organic Frameworks via Isomeric Biphenyldicarboxylates
Three new cadmium compounds, [CdÂ(2,4′-bpdc)Â(bib)<sub>0.5</sub>] (<b>1</b>; 2,4′-bpdc = biphenyl-2,4′-dicarboxylate
and bib = 1,4-bisÂ(2-methyl-imidazol-1-yl)Âbutane), {[Cd<sub>2</sub>(3,4′-bpdc)<sub>2</sub>(bib)<sub>1.5</sub>(H<sub>2</sub>O)]<sub><i>n</i></sub>·H<sub>2</sub>O}<sub><i>n</i></sub> (<b>2</b>; 3,4′-bpdc = biphenyl-3,4′-dicarboxylate),
and [Cd (4,4′-bpdc)Â(bib)] (<b>3</b>; 4,4′-bpdc
= biphenyl-4,4′-dicarboxylate), have been successfully synthesized
by the assembly of Cd<sup>2+</sup> ions, bib ligands, and isomeric
bpdc ligands, respectively. This paper presents a comparative study
on the tuning of structural topologies using three isomers of biphenyldicarboxylates
as bridging ligands. Compound <b>1</b> based on 2,4′-bpdc
features a three-dimensional (3D) framework with 6-connected <b>mab</b> topology. Compound <b>2</b> based on 3,4′-bpdc
is another 3D framework, but it possesses a rare 3-fold interpenetrating
4,6-connected <b>fsh</b> net, while compound <b>3</b> based
on linear 4,4′-bpdc shows unusual 2D → 3D parallel polycatenation
of (4,4) layers. Furthermore, the luminescent properties of three
compounds are investigated in the solid state
