Lichen planus is a darkly pigmented skin disease that impairs the quality of life of patients. The effect of lichen planus on patient's quality of life (QoL) is not widely documented. The study's objective was to determine QoL impairment of LP patients, determine what aspect of QoL is impaired, and correlate clinical and sociodemographic characteristics with QOL impairment.

This was a cross-sectional descriptive study conducted from February 2018 to January 2019 at the outpatient dermatology clinic of the Lagos State University Teaching Hospital, Lagos, Nigeria. All consecutive newly diagnosed LP patients who gave their consent were recruited into the study. Socio-demographic data and QoL (using the dermatology life quality index, DLQI) was documented. The hospital's ethical committee gave ethical approval for the study. The patients were clinically examined. Statistical analysis was done using SPSS version 22. The level of significance of all tests was set at 5%.

Quality of life was impaired in 95.5% of the patients. The mean DLQI score was 10±6.7. The minimum DLQI was one and the highest 24. Quality of life was mildly, moderately and severely impaired in 38.01%, 23.81% and 38.01% respectively. Pruritus was significantly associated with QoL impairment. Feelings of embarrassment (54.5%), itchy skin (54.5%), interference with being in public (54.5%), social life (50%) and having to deliberately choose clothes to cover the LP lesions (61.1%) were the main items impaired in the DLQI instrument.

Lichen planus affects QoL of patients negatively. The items of impairment are feelings of embarrassment, social functioning and choice of clothing.

Two entities have been associated with it, high altitude pulmonary hypertension and chronic mountain sickness. Its physiological and pulmonary circulation characteristics are described, as well as its clinical profile and diagnosis.
Sickle cell anaemia (SCA, HbSS) is a genetic disorder of haemoglobin with marked variation in clinical manifestation. The aim of this study was to determine the foetal haemoglobin (HbF) status of patients with HbSS, compared with that of individuals with HbAS and HbAA control as well as to establish the relationship between HbF level and age and gender of the participants.

This was a cross-sectional study in which HbF values of known HbSS patients along with HbAS and HbAA controls were analysed using High Performance Liquid Chromatography. Socio-demographic and other information were obtained with the use of questionnaire. Data was analyzed using SPSS software, version 20.0. Ethical approval was obtained for the study.

One hundred and two (102) participants were recruited for the study, comprising 60 patients with HbSS, 22 HbAS and 20 HbAA controls, with mean age of 11.0 years±9.6, 11.7 years ±8.8 and 12.3 years±8.1 respectively. There were 30 (61.2%) males and 30 (56.6%) females for HbSS group, 9 (18.4bin level tend to decrease with advancing age and higher in females. Increased HbF level may play a compensatory mechanism in sickling in HbSS, thus the use of agent that increase HbF level may improve clinical outcome.
To explore the biological function of miR-425/PAK4 axis in proliferation, metastasis, and apoptosis of ovarian cancer (OC) cells.

qRT-PCR and Western blot were adopted to examine miR-425 and PAK4 expressions in OC tissues and cell lines. Cell counting kit-8 (CCK-8) and BrdU assays were applied to detect the proliferation ability of OC cells, and Transwell assay was adopted to assess the migration and invasion of OC cells. Flow cytometry was employed to evaluate the apoptosis of OC cells. Selleckchem 2-Bromohexadecanoic The interaction between miR-425 and PAK4 was predicted and verified by bioinformatics analysis and dual luciferase reporter gene assay, respectively.

miR-425 was reduced in OC tissues and cell lines, and its underexpression was in evident correlation with the shorter overall survival time of OC patients. miR-425 impeded OC cell proliferation, migration, and invasion, and accelerated apoptosis. Additionally, PAK4 was validated as the target of miR-425, and the cotransfection of PAK4 reversed the antitumor effect of miR-425.

miR-425 suppresses the proliferation, migration, and invasion of OC cells and enhances apoptosis via inhibiting PAK4, and it is expected to be a prognostic indicator and therapeutic target for the patients with OC.

In this study, we treated effluent from a paper mill in sequencing batch reactors (SBRs) and monitored the abundance and activity of NFB with a view to producing a sludge that could work as a biofertilizer. Four reactors were inoculated with activated sludge enriched with NFB and fed with a high C/N waste (1000.5) from a paper mill. Though the reactors were able to reduce the organic load of the wastewater by up to 89%, they did not have any nitrogen-fixing activity and showed a decrease in the putative number of NFB (quantified with qPCR). The most abundant species in the reactors treating high C/N paper mill wastewater was identified by Illumina MiSeq 16S rRNA gene amplicon sequencing as Methyloversatilis sp. (relative abundance of 4.4%). Nitrogen fixation was observed when the C/N ratio was increased by adding sucrose. We suspect that real-world biological nitrogen fixation (BNF) will only occur where there is a C/N ratio ≤1000.07. Consequently, operators should actively avoid adding or allowing nitrogen in the waste streams if they wish to valorize their sludge and reduce running costs. PRACTITIONER POINTS Efficient biological wastewater treatment of low nitrogen paper mill effluent was achieved without nutrient supplementation. The sludge was still capable of fixing nitrogen although this process was not observed in the wastewater treatment system. This high C/N wastewater treatment technology could be used with effluents from cassava flour, olive oil, wine and dairy industries.
