TL;DR: The interval between the diffraction spots was the closest yet reported by avoiding mutual interference among their side lobes by using a parallel femtosecond laser irradiation system with arbitrary polarization distribution control using a pair of spatial light modulators.
Abstract: A parallel femtosecond pulse irradiation method using a computer-generated hologram displayed on a spatial light modulator provides the advantages of high throughput and high energy-use efficiency. Polarization control of the femtosecond pulse enables some unique properties, for example, selective excitation of an anisotropic molecule, focusing at a size beyond the diffraction limit owing to the longitudinal vector component of a radially polarized beam focused by a high-numerical-aperture objective lens, and fabrication of periodic nanostructures with femtosecond laser light. In this study, we propose a parallel femtosecond laser irradiation system with arbitrary polarization distribution control using a pair of spatial light modulators. By using the system, the interval between the diffraction spots was the closest yet reported by avoiding mutual interference among their side lobes. The interval was improved to half compared with our previous work. We also demonstrated the parallel fabrication of periodic nanostructures with orientation control, which, to our knowledge, is the first reported demonstration of its kind.

TL;DR: The hypothesis that NPY plays a central role in regulation of energy homeostasis, with especially important effect on feeding behavior and body weight in broiler chickens, is supported.
Abstract: To examine the neural mechanism by which hypothalamic neuropeptide Y (NPY) regulates energy homeostasis and feeding behavior in commercial broilers, we measured NPY content in several hypothalamic regions of birds that were fasted and then refed. After fasting for 48 and 72 h, body weight significantly decreased, and food intake significantly increased during the subsequent refeeding. The lost body weight was not restored to ad libitum feeding levels even after 3 days of refeeding. Plasma glucose concentration and body fat content significantly decreased and plasma non-esterified fatty acid (NEFA) concentration significantly increased after 48- and 72-h fasting. Refeeding for 24 h restored plasma metabolites and body fat content to pre-fasting levels. NPY content in the paraventricular nucleus (PVN) and infundibular nucleus significantly increased during fasting, and NPY content of the PVN was restored to pre-fasting levels after 24-h refeeding. However, there was no significant change in the NPY content of the lateral hypothalamic area during fasting or refeeding. The present results of changes in the hypothalamic NPY content during fasting and refeeding support the hypothesis that NPY plays a central role in regulation of energy homeostasis, with especially important effect on feeding behavior and body weight in broiler chickens.

TL;DR: The results indicate another function of cathepsin B and insect hemocyte during metamorphosis as well as in situ hybridization, strong signals were observed in the granular cells and plasmatocytes of day 0 pupa, but not in those of day 5 of the fifth larval instar.
Abstract: By using RT-PCR and 5′- and 3′-RACE methods, we isolated cathepsin B cDNA from hemocytes of Bombyx mori . The predicted open reading frame encoded 337 amino acids with 54% identity with the human cathepsin B, and 55% identity with the 29-kDa proteinase of the blowfly. Three active sites characteristic for cathepsin B were conserved in the deduced amino acid sequences of BmCtB cDNA at positions Cys-111, His-280 and Asn-300. Northern analysis identified a 1.3-kb mRNA. Expression of BmCtB was observed in the hemocytes from the day of wandering and was strongest at day 1 pupa. With in situ hybridization, strong signals were observed in the granular cells and plasmatocytes of day 0 pupa, but not in those of day 5 of the fifth larval instar. The results indicate another function of cathepsin B and insect hemocyte during metamorphosis.
