1. We studied the effect of varying excitatory and inhibitory drive on the N-methyl-D-aspartate (NMDA) receptor-mediated component of the visual responses of neurons in the cat dorsal lateral geniculate nucleus (dLGN) by varying the contrast and size of stimuli presented to the receptive fields of these cells. 2. Cells were classified as either on- or off-center, X or Y, and lagged or nonlagged...

Sprouty negatively modulates branching morphogenesis in the Drosophila tracheal system. To address the role of mammalian Sprouty homologues in angiogenesis, another form of branching morphogenesis, a recombinant adenovirus engineered to express murine Sprouty-4 selectively in endothelial cells, was injected into the sinus venosus of embryonic day 9.0 cultured mouse embryos. Sprouty-4 expression...

Tulisan ini mengkaji kualitas parameter akustik, dari lima ruangan di Univeristas XYZ, yang terbagi ke dalam tiga klaster fungsi (studio, ruang rapat, dan kelas). Rekaman suara sumber impulsif dianalisis dengan menggunakan perangkat lunak REW untuk menghasilkan reverberation time RT60 speech clarity C50 dapat digunakan memeringkat kelima tersebut. Analisis menunjukkan adanya korelasi erat antar...

Over the course of evolution, nature continually discovers new small molecules through the alteration of biosynthetic enzymes and pathways by mutation and gene transfer. Hundreds of these natural products have proven indispensable to medicine, culture, and technology, greatly contributing to increases in the length and quality of human lives. Chemists have found that the “chemical space” surrou...

Aim: The aim of this study was to analyze the differences in size maxillary and mandibular dental arch between Papuan males females. Materials Methods: An analytical cross-sectional design carried out 12 females aged above 18–25 years Surabaya. Raberin method used measure arches width cast transversal (L33, L66, L77) sagittal direction (L31, L61, L71). statistical analysis data normality by Kol...

Aim: To evaluate the cardiovascular effect of carvacrol treatment in a D(+)galactose accelerated aging model, investigating effects on vascular reactivity, oxidative stress, and systolic blood pressure (SBP).
 Methodology: Eight-week-old male Wistar rats (Rattus norvegicus) were used for oral eight weeks. Organ baths reactivity studies (FEN, ACh, NPS), fluorescence microscopy to detect rea...
