Protein hydrolysate was prepared from Acetes indicus which is a major bycatch among non-penaeid prawn landings of India. Hydrolysis conditions (enzyme to substrate ratio and time) for preparing protein hydrolysates using alcalase enzyme were optimized by response surface methodology using central composite design. The optimum conditions for enzyme-substrate ratio (mL/100 g) of 1.57, 1.69, 1.60, 1.56, and 1.50 and for hydrolysis time of 97.18, 96.5, 98.15 min, 102.48, and 88.44 min were established for attaining maximum yield, degree of hydrolysis, 2,2-diphenyl-1-picrylhydrazyl, angiotensin I-converting enzyme-inhibiting activity, and metal-chelating activity, respectively...

The understanding of near-wall motion, evaporation behavior and dry pattern of sessile nanofluid droplets is fundamental to a wide range of applications such as painting, spray drying, thin film coating, fuel injection and inkjet printing. However, a deep insight into the heat transfer, fluid flow, near-wall particle velocity and their effects on the resulting dry patterns is still much needed to take the full advantage of these nano-sized particles in the droplet. This work investigates the effect of direct absorptive silicon/silver (Si/Ag) hybrid nanofluids via two experiments...

Tin monosulfide (SnS) is an emerging thin-film absorber material for photovoltaics. An outstanding challenge is to improve carrier lifetimes to >1 ns, which should enable >10% device efficiencies. However, reported results to date have only demonstrated lifetimes at or below 100 ps. In this study, we employ defect modeling to identify the sulfur vacancy and defects from Fe, Co, and Mo as most recombination-active. We attempt to minimize these defects in crystalline samples through high-purity, sulfur-rich growth and experimentally improve lifetimes to >3 ns - thus achieving our 1 ns goal...

Patterning of the facial skeleton involves the precise deployment of thousands of genes in distinct regions of the pharyngeal arches. Despite the significance for craniofacial development, how genetic programs drive this regionalization remains incompletely understood. Here we use combinatorial labeling of zebrafish cranial neural crest-derived cells (CNCCs) to define global gene expression along the dorsoventral axis of the developing arches. Intersection of region-specific transcriptomes with expression changes in response to signaling perturbations demonstrates complex roles for Endothelin1 (Edn1) signaling in the intermediate joint-forming region, yet a surprisingly minor role in ventral-most regions...

The plant cellulose synthase gene superfamily belongs to the category of type-2 glycosyltransferases, and is involved in cellulose and hemicellulose biosynthesis. These enzymes are vital for maintaining cell-wall structural integrity throughout plant life. Here, we identified 78 putative cellulose synthases (CS) in the soybean genome. Phylogenetic analysis against 40 reference Arabidopsis CS genes clustered soybean CSs into seven major groups (CESA, CSL A, B, C, D, E and G), located on 19 chromosomes (except chromosome 18)...

The pineal gland has a deep central location, making it a surgeon's no man's land. Surgical pathology within this territory presents a unique challenge and an opportunity for employment of various surgical techniques. In modern times, the microsurgical technique has been competing with the endoscope for achieving superior surgical results. We describe two cases utilizing a purely endoscopic and an endoscopic-assisted supracerebellar infratentorial approach in accessing lesions of the pineal gland. We also discuss our early learning experience with these approaches...

Systemic lupus erythematosus (SLE) is an autoimmune disease that is frequently treated with high doses of corticosteroids and other immunosuppressive drugs. Thus patients with SLE are at increased risk for infections with several pathogens including Mycobacterium tuberculosis. There are no established guidelines available for treatment of tuberculosis in SLE patients with high disease activity due to lack of relevant studies and management based more on physician expertise. We report a case of a young SLE patient with high disease activity index (SLEDAI19) as evidenced by the presence of a vasculitic rash, non-healing ulcer on forearm and proteinuria of >1 g/d along with miliary tuberculosis...

Blue organic light-emitting diodes (OLEDs) are necessary for flat-panel display technologies and lighting application. To make more energy saving, low cost and long-lasting OLEDs, efficient materials as well as simple structured devices are highly demanded. However, a very limited number of blue OLEDs achieving high stability and color purity are reported. Herein, three new sky-blue emitters, TPEI, TPEMeOPhI and 3TPEI, with the combination of imidazole and tetraphenylethene groups have been developed. High photoluminescence quantum yields are obtained for these materials...

Major depressive disorder (MDD) is the most common non-motor manifestation of Parkinson's disease (PD) affecting 50% of patients. However, little is known about the cognitive correlates of MDD in PD. Using a computer-based cognitive task that dissociates learning from positive and negative feedback, we tested four groups of subjects: (1) patients with PD with comorbid MDD, (2) patients with PD without comorbid MDD, (3) matched patients with MDD alone (without PD), and (4) matched healthy control subjects. Furthermore, we used a mathematical model of decision-making to fit both choice and response time data, allowing us to detect and characterize differences between the groups that are not revealed by cognitive results...
