Given a passage with a context and an answer, construct a question on the basis of the information present in the passage. Construct the question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) it answer uses text phrases from the passage. Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.

Context: Dentofacial deformities are dys-morpho-functional disorders involving the temporomandibular joints (TMJ). Many authors have reported a TMJ improvement in dysfunctional subjects with malocclusion after orthodontic or combined orthodontic and surgical treatment particularly for the relief of pain. In particular, few studies have highlighted the demographic and clinical predictors of response to surgical treatment. To date, no genetic factor has yet been identified as a predictor of response to surgical treatment. The aim of this cohort study is therefore to identify single-nucleotide polymorphisms associated with postoperative temporomandibular disorders (TMD) or with TMJ symptoms after orthognathic surgery. Here, we found the AA genotype of SNP rs1643821 (ESR1 gene) as a risk factor for dysfunctional worsening after orthognathic surgery. In addition, we have identified TT genotype of SNP rs858339 (ENPP1 gene) as a protective factor against TMD in a population of patients with dentofacial deformities. Conversely, the heterozygous genotype AT was identified as a risk factor of TMD with respect to the rest of our population. All these elements are particularly important to bring new screening strategies and tailor future treatment.
Answer: This study allows us to identify sub-populations at high risk of developing postoperative temporomandibular disorders after orthognathic surgery procedures. Many other genes of interest could be potential factors influencing the dysfunctional response to orthognathic surgery, particularly genes of the Opera cohort.

Ex Output:
Do eNPP1 and ESR1 genotypes influence temporomandibular disorders development and surgical treatment response in dentofacial deformities?

Context: Biological evidence reported in the literature supports the role of CELSR1 as being essential for valvular function in murine lymphatics. Yet thus far, there have been no variants in CELSR1 associated with lymphatic dysfunction in humans.', 'In this report, a rare early inactivating mutation in CELSR1 is found to be causal for non-syndromic, lower extremity lymphedema in a family across three generations. Near-infrared fluorescence lymphatic imaging shows that instead of being propelled within the lumen of well-defined lymphatic vessels, lymph moved in regions of both legs in an unusual fashion and within sheet-like structures.
Answer: CELSRI may be responsible for primary, non-syndromic lymphedema in humans.

Ex Output:
Is a novel mutation in CELSR1 associated with hereditary lymphedema?

Context: The potential to modulate the inflammatory response has renewed interest in hypertonic saline (HTS) resuscitation of injured patients. However, the effect of the timing of HTS treatment with respect to polymorphonuclear neutrophil (PMN) priming and activation remains unexplored. We hypothesized that HTS attenuation of PMN functions requires HTS exposure before priming and activation.', 'Isolated PMN were incubated in HTS (180 mM Na+) before L-alpha-phosphatidylcholine, beta-acetyl-gamma-O-alkyl (PAF)/N-formylmethionyl-leucyl-phenylalanine (fMLP) priming/activation, after priming, or after priming/activation. Superoxide production was measured by the reduction cytochrome c, elastase release by cleavage of AAPV-pNA, and beta2-integrin expression by flow cytometry.', 'HTS before priming or activation decreased beta2-integrin expression, superoxide production, and elastase release. In contrast, HTS after priming/activation augmented superoxide production and elastase release.
Answer: The timing of HTS is a key variable in the attenuation of PMN cytotoxic functions. Maximal attenuation of cytotoxicity is achieved before priming, whereas HTS exposure after activation augments cytotoxicity.

Is hypertonic saline attenuation of polymorphonuclear neutrophil cytotoxicity : timing everything?
