In this task, you are given a passage which has a question and the context. You have to generate an answer to the question based on the information present in the context.

Context: Intraflagellar transport (IFT) is a motility process operating between the ciliary/flagellar (interchangeable terms) membrane and the microtubular axoneme of motile and sensory cilia. Multipolypeptide IFT particles, composed of complexes A and B, carry flagellar precursors to their assembly site at the flagellar tip (anterograde) powered by kinesin, and turnover products from the tip back to the cytoplasm (retrograde) driven by cytoplasmic dynein. IFT is essential for the assembly and maintenance of almost all eukaryotic cilia and flagella, and mutations affecting either the IFT motors or the IFT particle polypeptides result in the inability to assemble normal flagella or in defects in the sensory functions of cilia.', 'We found that the IFT complex B polypeptide, IFT27, is a Rab-like small G protein. Reduction of the level of IFT27 by RNA interference reduces the levels of other complex A and B proteins, suggesting that this protein is instrumental in maintaining the stability of both IFT complexes. Furthermore, in addition to its role in flagellar assembly, IFT27 is unique among IFT polypeptides in that its partial knockdown results in defects in cytokinesis and elongation of the cell cycle and a more complete knockdown is lethal.\Question: Is intraflagellar transport protein 27 a small G protein involved in cell-cycle control?
IFT27, a small G protein, is one of a growing number of flagellar proteins that are now known to have a role in cell-cycle control.

Context: To investigate the effects of interval aerobic training combined with strength-endurance exercise (IASE) and caloric restriction (CR) on body composition, glycaemic and lipid profile and inflammatory markers.', 'Thirty-two Zucker diabetic fatty rats were randomised into 4 groups (sedentary\xa0+\xa0CR; sedentary\xa0+\xa0adlibitum; IASE\xa0+\xa0CR; and IASE\xa0+\xa0adlibitum). Training groups conducted an IASE programme in the same session, 5 days/week for 2 months. Body weight, fat and muscle mass and body water were measured using a body composition analyser. Plasma total, LDL and HDL cholesterol, phospholipids, triglycerides, insulin, adiponectin, tumour necrosis factor alpha, interleukin 1 and 10 were measured. Blood fasting and postprandial glucose were assessed. Body weight was lower in the CR compared to the adlibitum groups (p\xa0<\xa00.001). Fat mass was lower in the CR compared to the adlibitum (p\xa0<\xa00.05) and in the IASE compared to the sedentary groups (p\xa0<\xa00.001), but IASE increased lean mass (p\xa0<\xa00.001). Triglycerides were lower in the CR compared to the adlibitum groups (p\xa0<\xa00.001) whereas total and LDL-cholesterol and fasting glucose were reduced only in the IASE groups (all, p\xa0<\xa00.001). Phospholipids decreased in the CR compared to the adlibitum (p\xa0<\xa00.05) and the IASE compared to the sedentary groups (p\xa0<\xa00.001). The area under the curve after oral glucose tolerance test, insulin and homoeostatic model assessment were lower in the IASE and the CR compared to the sedentary and adlibitum groups, respectively (all, p\xa0<\xa00.001). Adiponectin was lower in the CR groups (p\xa0<\xa00.001).\Question: Does interval aerobic training combined with strength-endurance exercise improve metabolic markers beyond caloric restriction in Zucker rats?
Overall, IASE as well as CR were both useful interventions, especially when combined. However, IASE showed greater improvements on body composition, inflammatory and glycaemic profile than CR did.

Context: Population-referenced total activity counts per day (TAC/d) percentiles provide public health practitioners a standardized measure of physical activity (PA) volume obtained from an accelerometer that can be compared across populations. The purpose of this study was to describe the application of TAC/d population-referenced percentiles to characterize the PA levels of population groups relative to US estimates.', 'A total of 679 adults participating in the 2011 NYC Physical Activity Transit survey wore an ActiGraph accelerometer on their hip for seven consecutive days. Accelerometer-derived TAC/d was classified into age- and gender-specific quartiles of US population-referenced TAC/d to compare differences in the distributions by borough (N=5).', 'Males in Brooklyn, Manhattan, and Staten Island had significantly greater TAC/d than US males. Females in Brooklyn and Queens had significantly greater levels of TAC/d compared to US females. The proportion of males in each population-referenced TAC/d quartile varied significantly by borough (χ(2)(12)=2.63, p=0.002), with disproportionately more men in Manhattan and the Bronx found to be in the highest and lowest US population-referenced TAC/d quartiles, respectively. For females, there was no significant difference in US population-reference TAC/d quartile by borough (χ(2)(12)=1.09, p=0.36).\Question: Does use of population-referenced total activity count percentiles to assess and classify physical activity of population groups?

These results demonstrate the utility of population-referenced TAC/d percentiles in public health monitoring and surveillance. These findings also provide insights into the PA levels of NYC residents relative to the broader US population, which can be used to guide health promotion efforts.
