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: Coagulation Factor XIII (FXIII) plays an important role in wound healing by stabilizing fibrin clots and cross-linking extracellular matrix proteins. FXIII is expressed in cells of the monocyte/macrophage and dendritic cell lineages in response to type 2 cytokines.', 'We sought to determine the association between FXIII and asthma pathobiology.', 'We analyzed the expression of FXIII mRNA and protein levels in bronchoalveolar lavage samples obtained before and after segmental allergen challenge from patients with mild asthma and in induced sputum samples collected from patients with mild-to-moderate and severe asthma.', 'FXIII mRNA and protein levels were highly upregulated in bronchoalveolar cells and fluid after allergen challenge and mRNA levels correlated with protein levels. In sputum of asthmatic patients, FXIII expression was positively correlated with type 2 immune response and dendritic cell markers (CD209 and CD207). FXIII expression was also associated with increased airflow limitation (FEV1/forced vital capacity and residual volume/total lung capacity ratios) and greater reversibility to β-agonists.\Question: Does airway factor XIII associate with type 2 inflammation and airway obstruction in asthmatic patients?
FXIII expression was upregulated in the airways of asthmatic patients after allergen exposure. Expression in the sputum of asthmatic patients correlated with the type 2 immune response and airflow limitation. Excessive activity of FXIII could contribute to the pathophysiology of airway obstruction in asthmatic patients.

Context: To clarify the pathways between household livestock and child growth by assessing the relationships between consumption of animal-source foods (ASF) and child growth and evaluating the household livestock correlates of child consumption of ASF.', 'We conducted a longitudinal cohort study of anthropometry and 3 d feeding recalls among children <5 years old between June 2014 and May 2015. In addition, we collected data on wealth, livestock ownership and livestock diseases in the same households. We used linear and negative binomial mixed models to evaluate the relationships between household livestock characteristics, reported consumption of ASF and child growth.', 'An 1800-household surveillance catchment area in Western Kenya within the structure of human and animal health surveillance systems.', 'Children (n 874) <5 years old.', 'Among children >6 months old, reported frequency of egg and milk consumption was associated with increased monthly height gain (for each additional report of consumption over 3 d: adjusted β (95 % CI)=0·010 (0·002, 0·019) cm/month and 0·008 (0·004, 0·013) cm/month, respectively). Poultry ownership was associated with higher reported frequency of egg, milk and chicken consumption (adjusted incidence rate ratio (95 % CI)=1·3 (1·2, 1·4), 1·4 (1·1, 1·6) and 1·3 (1·1, 1·4), respectively). Some livestock diseases were associated with lower reported frequency of ASF intake (livestock digestive diseases-adjusted incidence rate ratio (95 % CI)=0·89 (0·78, 1·00)).\Question: Is child height gain associated with consumption of animal-source foods in livestock-owning households in Western Kenya?
Child height gain was associated with milk and egg consumption in this cohort. ASF consumption was related to both household livestock ownership and animal health.

Context: To investigate the role of T helper-1 cell (Th1) activation in the induction of proinflammatory cytokine production and cartilage damage by rheumatoid arthritis (RA) synovial fluid mononuclear cells (SFMNC) and the subsequent possible beneficial role of the T helper-2 cell (Th2) cytokine interleukin-4 (IL-4) in the inhibition of this process.', 'SFMNC were stimulated with bacterial antigen (hsp60) to activate Th1 cells. Th1 and Th2 specific cytokine profiles (interferon gamma (IFN gamma) and IL-4) and proinflammatory cytokines interleukin-1 (IL-1) and tumour necrosis factor alpha (TNF alpha) in the conditioned media were analysed. In addition, the conditioned media were tested for their ability to induce cartilage damage. The same parameters were measured in the presence of IL-4.', 'Stimulation of SFMNC with bacterial antigen resulted in an increase in IFN gamma, IL-1, and TNF alpha production which was accompanied by the induction of cartilage damage. Th1 activation could be inhibited by IL-4 as shown by a reduction of IFN gamma. This was accompanied by a decrease in IL-1 and TNF alpha production and inhibition of cartilage damage.\Question: Is proinflammatory cytokine production and cartilage damage due to rheumatoid synovial T helper-1 activation inhibited by interleukin-4?

Th1 activation is a possible mechanism by which inflammation in RA joints is enhanced. The Th2 cytokine IL-4 inhibits this Th1 activity and may diminish inflammation and induction of cartilage damage in RA joints.
