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.

Question: Context: Information about malaria risk factors at high altitudes is scanty. Understanding the risk factors that determine the risk of malaria transmission at high altitude villages is important to facilitate implementing sustainable malaria control and prevention programs.', 'An unmatched case control study was conducted among patients seeking treatment at health centers in high altitude areas. Either microscopy or rapid diagnostic tests were used to confirm the presence of plasmodium species. A generalized linear model was used to identify the predictors of malaria transmission in high altitude villages.', 'Males (AOR\u200a=\u200a3.11, 95%CI: 2.28, 4.23), and those who traveled away from the home in the previous month (AOR\u200a=\u200a2.01, 95% CI: 1.56, 2.58) were strongly associated with presence of malaria in high altitude villages. Other significant factors, including agriculture in occupation (AOR\u200a=\u200a1.41, 95% CI: 1.05, 1.93), plants used for fencing (AOR\u200a=\u200a1.70, 95% CI: 1.18, 2.52) and forests near the house (AOR\u200a=\u200a1.60, 95% CI: 1.15, 2.47), were found predictors for malaria in high altitude villages.\Question: Are men traveling away from home more likely to bring malaria into high altitude villages , northwest Ethiopia?

Answer: Travel outside of their home was an important risk of malaria infections acquisition. Targeting males who frequently travel to malarious areas can reduce malaria transmission risks in high altitude areas.


Question: 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?

Answer: 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.


Question: Context: Clinical evidence indicates that hemodynamic conditions influence abdominal aortic aneurysm (AAA) disease. We modified blood flow to evaluate the effects of wall shear stress (WSS) and relative wall strain (RWS) on aneurysm structure and cellularity.', 'Rodent AAAs were created with porcine pancreatic elastase infusion. In group 1 AAA WSS was increased with left femoral arteriovenous fistula creation, whereas in group 2 AAA WSS was decreased with left iliac artery ligation. Aortic flow, wall motion, and blood pressure were recorded in both groups. AAA diameter, endothelial and smooth muscle cellularity (CD31 and alpha-smooth muscle actin immunostaining), markers for cell proliferation (5-bromodeoxyuridine), endothelial and smooth muscle cell growth factor production (vascular endothelial growth factor-D and platelet-derived growth factor-beta, respectively), and apoptosis (deoxyuridine triphosphate nick end-labeled [TUNEL] stain) were compared between groups when the animals were killed.', 'Arteriovenous fistula creation increased WSS (high-flow AAA) by 300% and RWS by 150%. Iliac ligation reduced WSS (low-flow AAA) by 60%. Neither procedure significantly altered systolic, diastolic, or mean aortic pressure. When the animals were killed 7 days after elastase infusion, low-flow AAAs were significantly larger than high-flow AAAs. High-flow AAAs also contained more endothelial cells and smooth muscle cells, and evidence of increased growth factor production, cell proliferation, and decreased apoptosis. No difference in type or severity of AAA inflammatory cell infiltrate was noted between groups.\Question: Do wall shear stress and strain modulate experimental aneurysm cellularity?

Answer:
High flow conditions stimulate endothelial cell and smooth muscle cell proliferation in experimental aneurysms. Enhanced cellularity may stabilize aortic integrity, limiting aneurysm growth. Increased lower extremity activity may prevent or retard AAA disease through salutary effects on aortic remodeling mediated by endothelial cells and smooth muscle cells.
