A mathematical model of the processes involved in carbon metabolism is described that predicts the influence of temperature on the growth of plants. The model assumes that the rate of production of dry matter depends both on the temperature and the level of nonstructural carbohydrate. The level of nonstructural carbohydrate is determined by the rates of photosynthesis, growth, and maintenance r...

The nucleotide sequence coding for the nonstructural proteins of Semliki Forest virus has been determined from cDNA clones. The total length of this region is 7381 nucleotides, it contains an open reading frame starting at position 86 and ending at an UAA stop codon at position 7379-7381. This open reading frame codes for a 2431 amino acids long polyprotein, from which the individual nonstructu...

Exposure to hepatitis C virus (HCV) is associated with a high prevalence of persistent viral infection and the development of chronic liver disease and hepatocellular carcinoma. Recovery from acute infection may depend upon the generation of broad-based cellular immune responses to viral structural and nonstructural proteins. We used the DNA-based immunization approach in BALB/c mice to determi...

Most control techniques in the structural engineering literature are aimed at improving performance of the primary structural system, but may have limited or even adverse effect on nonstructural components during strong seismic events. In this paper, we emphasize nonstructural performance using an active controller with a cubic nonlinearity. The controller is optimized based on the frequency re...

Nonstructural carbohydrate reserves support tree metabolism and growth when current photosynthates are insufficient, offering resilience in times of stress. We monitored stemwood nonstructural carbohydrate (starch and sugars) concentrations of the dominant tree species at three sites in the northeastern United States. We estimated the mean age of the starch and sugars in a subset of trees using...

Objective Mutations in HCV nonstructural protein 5A (NS5A) play a vital role in virus resistance. The aim of this study was to develop a correlation between NS5A mutations (genotype 3a) and virological response towards interferon alpha (IFN-α) plus ribavirin therapy. Methods In this study, which was conducted from 09-02-2013 to 25-11-2015 in the rural area of Province Sindh - Pakistan, total ...

Most of the seven flavivirus nonstructural proteins (NS1 to NS5) encoded in the distal two-thirds of the RNA positive-sense genome are believed to be essential components of RNA replication complexes. To explore the functional relationships of these components in RNA replication, we used trans-complementation analysis of full-length infectious RNAs of Kunjin (KUN) virus with a range of lethal i...

Background and objectivesSevere acute respiratory syndrome coronavirus (SARS-CoV) 2 infection has caused millions of deaths worldwide, pushing the urgent need for an efficient treatment. Nonstructural protein 15 (NSP15) is a promising target due to its importance SARS-CoV-2’s evasion host’s innate immune response.

materials and methods a total of 300 day-old broiler chicks (ross 308) divided into three equal groups (1 to 3) .the chicks in group 1 were immunized with killed aiv h9n2. the chicks in group 2 were infected with ai virus subtype h9n2. the chicks in group 3 were kept as controls and did not receive any vaccined or lived virus. chicks sera were collected at day 42 usingrns1-elisa and commercial ...
