Chemosensory sensitivity reflects reproductive status in the ant Harpegnathos saltator. [PDF]

, 2017
Insects communicate with pheromones using sensitive antennal sensilla. Although trace amounts of pheromones can be detected by many insects, context-dependent increased costs of high sensitivity might lead to plasticity in sensillum responsiveness.

Dual PI3K/AKT and CDK4/6 inhibition reveals selective sensitivity in an SHH medulloblastoma stem cell model

Molecular Oncology, EarlyView.
Targeted therapy was evaluated in SHH medulloblastoma using neuroepithelial stem cell (NES) and tumor‐derived NES‐like (tNES) models in 2D monolayers and 3D spheroids. PI3K, AKT, and CDK4/6 inhibitors had minimal effects in NES but markedly reduced viability and growth and induced apoptosis in tNES cells, revealing distinct therapeutic vulnerabilities.

Vapour-liquid equilibrium of the OPLS, optimized potentials for liquid simulations, model for binary systems of alkanes and alkanes + alcohols [PDF]

Journal of the Serbian Chemical Society, 2005
The NpT - Gibbs ensemble Monte Carlo computer simulation method was applied to predict the vapour-liquid equilibrium (VLE) behavior of the binary systems ethane + pentane at 277.55 K and 310.95 K, ethane + hexane at 298.15 K, propane + methanol at 313.15

Reactions of C$_2$({\it a}$^3Pi_u$) with selected saturated alkanes: A temperature dependence study

, 2010
We present a temperature dependence study on the gas phase reactions of the C$_2$({\it a}$^3Pi_u$) radical with a selected series of saturated alkanes (C$_2$H$_6$, C$_3$H$_8$, n-C$_4$H$_10$, i-C$_4$H$_10$, and n-C$_6$H$_14$) by means of pulsed laser ...

Characterization of carbon monoxide, methane and nonmethane hydrocarbons in emerging cities of Saudi Arabia and Pakistan and in Singapore [PDF]

, 2016
We investigate the composition of 63 C2-C10 nonmethane hydrocarbons (NMHCs), methane (CH4) and carbon monoxide (CO), in Jeddah, Mecca, and Madina (Saudi Arabia), in Lahore, (Pakistan), and in Singapore. We established a database with which to compare and

Establishment of a humanized patient‐derived xenograft mouse model of high‐grade serous ovarian cancer for preclinical evaluation of combination immunotherapy

Molecular Oncology, EarlyView.
We have established a humanized orthotopic patient‐derived xenograft (Hu‐oPDX) mouse model of high‐grade serous ovarian cancer (HGSOC) that recapitulates human tumor–immune interactions. Using combined anti‐PD‐L1/anti‐CD73 immunotherapy, we demonstrate the model's improved biological relevance and enhanced translational value for preclinical ...

Note on the Hyper-Wiener Index [PDF]

Journal of the Serbian Chemical Society, 2003
The hyper-Wiener index WW of a chemical tree T is defined as the sum of the products n1n2, over all pairs u, u of vertices of T, where n1 and n2 are the number of vertices of T, lying on the two sides of the path which connects u and u.

Avanços metodológicos na determinação do consumo de ruminantes em pastejo Advances in methods for determining animal intake on pasture

Revista Brasileira de Zootecnia, 2007
Avanços metodológicos são, usualmente, conseqüência direta de avanços conceituais e tecnológicos. No caso da estimativa do consumo em pastejo, os recentes avanços conceituais relativos ao processo de busca e apreensão da forragem pelo ruminante ...

Quantifying sources of methane using light alkanes in the Los Angeles basin, California [PDF]

, 2013
Methane (CH4), carbon dioxide (CO2), carbon monoxide (CO), and C2-C5 alkanes were measured throughout the Los Angeles (L.A.) basin in May and June 2010. We use these data to show that the emission ratios of CH4/CO and CH4/CO2 in the L.A. basin are larger

The numbers of chiral and achiral alkanes and monosubstituted alkanes [PDF]

Tetrahedron, 1976
Abstract Whereas the theory for the enumeration of the optical isomers of the lakyl radicals and the alkanes has long been understood, this is not the case for the corresponding archiral isomers. We present for the first time recurrence formulae for counting the number of archiral isomers of the alkyl radicals and the alkanes. For chiral and archiral
