Abstract
BACKGROUND In low- and middle-income countries countries, millions of deaths occur annually from household air pollution (HAP), pulmonary tuberculosis (PTB), and HIV-infection. However, it is unknown whether HAP influences PTB risk among people living with HIV-infection. METHODS We conducted a case-control study among 1,277 HIV-infected adults in Bukavu, eastern Democratic Republic of Congo (February 2018 - March 2019). Cases had current or recent (<5y) PTB (positive sputum smear or Xpert MTB/RIF), controls had no PTB. Daily and lifetime HAP exposure were assessed by questionnaire and, in a random sub-sample (n=270), by 24-hour measurements of personal carbon monoxide (CO) at home. We used multivariable logistic regression to examine the associations between HAP and PTB. RESULTS We recruited 435 cases and 842 controls (median age 41 years, [IQR] 33-50; 76% female). Cases were more likely to be female than male (63% vs 37%). Participants reporting cooking for >3h/day and ≥2 times/day and ≥5 days/week were more likely to have PTB (aOR 1·36; 95%CI 1·06-1·75) than those spending less time in the kitchen. Time-weighted average 24h personal CO exposure was related dose-dependently with the likelihood of having PTB, with aOR 4·64 (95%CI 1·1-20·7) for the highest quintile [12·3-76·2 ppm] compared to the lowest quintile [0·1-1·9 ppm]. CONCLUSION Time spent cooking and personal CO exposure were independently associated with increased risk of PTB among people living with HIV. Considering the high burden of TB-HIV coinfection in the region, effective interventions are required to decrease HAP exposure caused by cooking with biomass among people living with HIV, especially women.

Abstract
Phenylketonuria (PKU) is a disorder characterized by an interruption in the conversion of phenylalanine to tyrosine, a reaction catalyzed by phenylalanine hydroxylase (PAH). Animal models of PKU used in this study were induced by daily subcutaneous injections of pups with alpha-methylphenylalanine plus phenylalanine in utero and postnatally from day 4 to day 14. Dry blood and plasma were utilized to measure phenylalanine concentration in PKU rats. The results indicated that the concentration of phenylalanine is higher and more stable in plasma than dry blood. Precolumn derivatization of dried blood and plasma free amino acids were conducted with phenylisothiocyanate (PITC). The phenylthiocarbamyl (PTC) derivatives were separated on a reversed-phase C-18 column (15 cm x 4.6 mm). A gradient high-performance liquid chromatography method with two eluents, 0.1 M sodium acetate buffer and 100% acetonitrile was developed to facilitate the separation of nine amino acids within 11 min. Tyrosine and phenylalanine eluted the column at 5.4 and 9.4 min, respectively. This method provides a quick and reliable technique for neonatal screening.
