Input: Consider Input: Context: Hair loss is related to follicular density, programmed regrowth and hair productivity.', 'The dissatisfaction with hair growth in patients experiencing hair loss might be due to slower linear hair growth rate (LHGR).', 'LHGR and hair diameter was evaluated in Caucasian controls and patients with patterned hair loss employing the validated non-invasive, contrast-enhanced-phototrichogram with exogen collection.', 'We evaluated 59,765 anagen hairs (controls 24,609, patients 35,156) and found thinner hairs grew slower than thicker hairs. LHGR in normal women was generally higher than in normal men. LHGR correlates with hair diameter (P < 0.006) and global thinning is associated with slower growth rates. Compared with hair of equal thickness in controls, subjects affected with patterned hair loss showed reduced hair growth rates, an observation found in both male and female patients. Males with pattern hair loss showed further reduction in growth rates as clinical severity worsened. However, sample size limitations prevented statistical evaluation of LHGR in severely affected females.
Answer: Caucasian ethnicity.

Output: Are gender differences in scalp hair growth rates maintained but reduced in pattern hair loss compared to controls?

Input: Consider Input: Context: Current views on the control of cell development are anchored on the notion that phenotypes are defined by networks of transcriptional activity. The large amounts of information brought about by transcriptomics should allow the definition of these networks through the analysis of cell-specific transcriptional signatures. Here we test this principle by applying an analogue to comparative anatomy at the cellular level, searching for conserved transcriptional signatures, or conserved small gene-regulatory networks (GRNs) on root hairs (RH) and pollen tubes (PT), two filamentous apical growing cells that are a striking example of conservation of structure and function in plants.', 'We developed a new method for isolation of growing and mature root hair cells, analysed their transcriptome by microarray analysis, and further compared it with pollen and other single cell transcriptomics data. Principal component analysis shows a statistical relation between the datasets of RHs and PTs which is suggestive of a common transcriptional profile pattern for the apical growing cells in a plant, with overlapping profiles and clear similarities at the level of small GTPases, vesicle-mediated transport and various specific metabolic responses. Furthermore, cis-regulatory element analysis of co-regulated genes between RHs and PTs revealed conserved binding sequences that are likely required for the expression of genes comprising the apical signature. This included a significant occurrence of motifs associated to a defined transcriptional response upon anaerobiosis.
Answer: Our results suggest that maintaining apical growth mechanisms synchronized with energy yielding might require a combinatorial network of transcriptional regulation. We propose that this study should constitute the foundation for further genetic and physiological dissection of the mechanisms underlying apical growth of plant cells.

Output: Does transcriptional profiling of Arabidopsis root hairs and pollen define an apical cell growth signature?

Input: Consider Input: Context: Limited studies have examined ethnic variation in breastfeeding and complementary feeding practices in developing countries. This study investigated ethnic variation in feeding practices in mothers with children 0-23 months old in Vietnam.', 'We used data on 1875 women who came from the ethnic majority, Kinh (n=989, randomly sampled from 9875 surveyed Kinh mothers, 10% from each province) and three ethnic minorities: E De-Mnong (n=309), Thai-Muong (n=229) and Tay-Nung (n=348). Ethnic minorities were compared with the Kinh group using logistic regression model.', 'Prevalence of breastfeeding initiation within an hour of birth was 69% in Thai-Muong, but ~50% in other ethnicities. In logistic regression, the prevalence of breastfeeding within one hour was lower in Tay-Nung (OR: 0.54; 95% CI: 0.38, 0.77) than the majority Kinh. Prevalence of exclusive breastfeeding under 6months was 18, 10, 17, and 33% in Kinh, Thai-Muong, Tay-Nung, and E De-Mnong, respectively; compared to the majority Kinh, the prevalence was lower in Thai-Muong (OR: 0.42; 95% CI: 0.25, 0.71) and higher in E De-Mnong (OR: 1.99; 95% CI: 1.04, 3.82). Overall prevalence of bottle feeding in Thai-Muong and E De-Mnong (~20%) was lower than in Kinh (~33%): Thai-Muong (OR: 0.50; 95% CI: 0.37, 0.68) and E De-Mnong (OR: 0.69; 95% CI: 0.50, 0.95). Compared with Kinh (75%), fewer ethnic minority children received minimum acceptable diets (33% in Thai-Muong, 46% in E De-Mnong, and 52% in Tay-Nung; P<0.05). Prevalence of minimum acceptable diet (met both dietary frequency and diversity) was lower in Thai-Muong (OR: 0.23; 95% CI: 0.11, 0.46), Tay-Nung (OR: 0.52; 95% CI: 0.39, 0.69), and E De-Mnong (OR: 0.55; 95% CI: 0.33, 0.89) than the majority Kinh.
Answer: Breastfeeding practices were suboptimal and differed by ethnicity, which suggests need for tailored interventions at multiple levels to address ethnic-specific challenges and norms. Complementary feeding practices were less optimal among ethnic minorities compared to Kinh, which suggests need for broad intervention including improved food availability, accessibility, and security.
Output: Do infant and young child feeding practices differ by ethnicity of Vietnamese mothers?
