Ctenoplusia agnata (Staudinger) (Lepidoptera: Noctuidae) is a highly destructive polyphagous pest of cotton, maize, soybean, and cruciferous vegetables in East Asia. The effect of various biotic and abiotic factors on the flight performance of C. agnata is crucial for a better understanding of its transregional migration. In this study, the flight performance of C. agnata moths at different ages, temperatures, and relative humidity (RH) levels, was examined by tethering individual moths to computerized flight mills for a 24-h scotophase...

The catalytic solvolysis of Norway spruce (Picea abies L.) lignin in a formic acid/water media was explored at different temperatures and reaction times (283-397°C and 21-700min, respectively). Non-catalyzed experiments were compared with the effect of three different type of bifunctional catalysts (Pd/Al2O3, Rh/Al2O3 and Ru/Al2O3) and a solid Lewis acid (γ-Al2O3). We demonstrated that surface response methodology (RSM) and principal component analysis (PCA) were an adequate tool to: (i) evaluate the effect of the catalysts, temperature and reaction time in the oil yield, oil quality (H/C and O/C ratios, and Mw) and composition of the oil, (ii) establish the differences and/or similarities between the three bifunctional catalyst and (iii) to determine the role of the noble metal and the alumina support in the reaction system...

The G antigen of Rh blood group system is present in almost all D-positive or C-positive red cells but absent from red cells lacking D and C antigens. The differentiation of anti-D and anti-C from anti-G is not necessary for routine transfusion; however, during pregnancy, it is important because anti-G can masquerade as anti-D and anti-C with initial antibody testing. The false presence of anti-D will exclude the patient from receiving anti-D immunoglobulin (RhIG) when the patient actually is a candidate for RhIG prophylaxis...

Temperature-controlled, solvent-free centrifugal spinning may be used as a means of rapid production of amorphous solid dispersions in the form of drug-loaded sucrose microfibers. However, due to the high content of amorphous sucrose in the formulations, such microfibers may be highly hygroscopic and unstable on storage. In this study, we explore both the effects of water uptake of the microfibers and the consequences of deliberate recrystallization for the associated dissolution profiles. The stability of sucrose microfibers loaded with three selected BCS class II model drugs (itraconazole (ITZ), olanzapine (OLZ) and piroxicam (PRX)) was investigated under four different relative humidity conditions (11, 33, 53 and 75% RH) at 25°C for 8 months, particularly focusing on the effect of the highest level of moisture (75% RH) on the morphology, size, drug distribution, physical state and dissolution performance of microfibers...

BACKGROUND: Despite local therapies, commonly transurethral resection (TUR) followed by adjuvant treatments, non-muscle-invasive bladder cancer (NMIBC) has a high rate of recurrence and progression. Intravesical Bacillus Calmette-Guérin (BCG) has been shown to reduce recurrence and progression in people with NMIBC following TUR, however many people do not respond to treatment, have recurrence shortly after, or cannot tolerate standard-dose therapy. The potential for synergistic antitumour activity of interferon (IFN)-alpha (α) and BCG provides some rationale for combination therapy for people who do not tolerate or respond to standard-dose BCG therapy...

Hypertension remains a major and growing public health problem associated with the greatest proportion of global cardiovascular (CV) morbidity and mortality. Although numerous factors contribute to poor blood pressure (BP) control and pseudo-resistance (i.e. unawareness, life-style habits, non-adherence to medication, insufficient treatment, drug-induced hypertension, undiagnosed secondary causes etc.), it is reported that true resistant hypertension (RH) is found in 10.1 % of patients treated for elevated BP...

In vitro transcription systems have been utilized to elucidate detailed mechanisms of transcription. Purified RNA polymerase II (pol II) and general transcription factors (GTFs) are required for the in vitro reconstitution of eukaryotic transcription systems. Among GTFs, TFIID and TFIIA play critical roles in the early stage of transcription initiation; TFIID first binds to the DNA in transcription initiation and TFIIA regulates TFIID's DNA binding activity. Despite the important roles of TFIIA, the time-consuming steps required to purify it, such as denaturing and refolding, have hampered the preparation of in vitro transcription systems...

Interferon-induced transmembrane proteins (IFITMs) have been recognized as important antiviral effectors of the innate immune system, both in cell culture and in infected humans. In particular, polymorphisms of the human IFITM3 gene have been shown to affect disease severity and progression in influenza A virus (FLUAV) and human immunodeficiency virus (HIV) infection, respectively. Rhesus macaques (Macaca mulatta) are commonly used to model human infections and the experimental inoculation of these animals with simian immunodeficiency virus (SIV) is one of the best models for HIV/AIDS in humans...

In supramolecular assemblies, absorption of water can assist the channel formation, similarly to biological systems and Nafion-like commercial ion-selective membranes. In this work, we investigate humidity-induced formation of water channels in wedge-shaped amphiphilic molecules, namely sodium 4'-[3'',4'',5''-tris(alkyloxy)benzoyloxy]azobenzene-4-sulfonates. The studied molecules contain a polar sulfonate group at the tip and a hydrophobic periphery composed of alkyl chains of two different lengths. Upon increasing the relative humidity (RH) the amount of absorbed water significantly increases for the mesogen with dodecyl chains as compared to the one with octyl groups...

Four solid forms of pranlukast (PRS) were obtained during mechanical milling including neat milling (NM) and solvent-drop milling (SDM), which were characterized by various analytical techniques. The effect of milling conditions including three milling temperatures and six assist solvents on the solid-state transformations of commercial PRS (PRS HH) were systemically investigated. Milling temperature significantly influenced the NM process. A low milling temperature (5 °C) led to a complete amorphization of PRS HH, while higher milling temperatures (15 °C and 30 °C) only induced a partial amorphization...
