Fusion proteins of biologic agents in the treatment of rheumatoid arthritis (RA): A network meta-analysis.

Background: To evaluate the efficacy of fusion proteins biologics (Etanercept (ETN), Anakinra (ANA), and Abatacept) combinations in the treatment of rheumatoid arthritis (RA) using network meta-analysis to rank those according to their performance medicines. The performance of these processes is ranked according to the results of the analysis and an explanatory study of the possible results is carried out.

Methods: Multiple databases including PubMed, EMBASE, and Cochrane Library were used to identify applicable articles and collect relevant data to analyze using STATA (14.

Flammability and Propagation Dynamics of Planar Freely Propagating Dimethyl Ether Premixed Flame.

Flammability dynamics and physics play a crucial role in fire safety and combustion efficiency. This paper numerically studied the flammability dynamics of dimethyl ether/air freely propagating premixed flame over a broad range of equivalence ratios (ϕ). The results showed that the traditional flammability range should be redefined considering the impact of low-temperature chemistry.

The extract from Agkistrodon halys venom protects against lipopolysaccharide (LPS)-induced myocardial injury.

Background: Snake venoms contain various bioactive constituents which possess potential therapeutic effects. The aim of this work was to investigate the effect of the extract from Agkistrodon halys venom on lipopolysaccharide (LPS)-induced myocardial injury.

Methods: Thirty male Sprague-Dawley rats were randomly assigned to three groups (10 rats per group): control group, LPS group and LPS + extract group.

[Effect of hydrogen sulfide on tissue factor-induced disseminated intravascular coagulation in rabbits].

Objective: To investigate the protective effect of hydrogen sulfide (H2S) on tissue factor-induced disseminated intravascular coagulation (DIC) in rabbits and its mechanism.

Methods: Thirty-two healthy rabbits were randomly divided into four groups: normal control group, NaHS control group, DIC model group, NaHS pretreatment group (each, n = 8). Ten minutes before model reproduction, rabbits in NaHS control and pretreatment groups were given 3.

Recovery of SO and MgO from By-Products of MgO Wet Flue Gas Desulfurization.

An industrial demonstration unit using natural gas as a heat source was built to calcine the by-products of MgO wet flue gas desulfurization from power plants; influencing factors on the SO content in calciner gas were comprehensively analyzed; and an advantageous recycling condition of MgO and SO from by-products was summarized. Results showed that the SO content in the calciner gas was increased by more than 10 times under a lower excess air coefficient, a higher feed rate, a lower crystal water in by-products, and a higher feed port position. For the tests conducted under the excess air coefficient above and below one, the effect of the furnace temperature on the SO content in the calciner gas was reversed.

The role of social support on occupational stress among hospital nurses.

Stress is a nonspecific reaction to everything the body needs. Although occupational stress exists in every occupation, it is seen with more frequency and intensity amongst those occupations related to human health. In this study, we aimed to investigate the relationship between occupational stress and social support (SS) among hospital nurses.

[Factors affecting the quality of life of elderly diabetic patients: survey in north and south Wanjiang river regions].

Objective: To investigate the quality of life of elderly diabetic patients and its influencing factors.

Methods: By randomized cluster sampling, we conducted a survey in 1450 elderly residents (over 60 years old) living in urban, suburban and rural areas in south and north Anhui province. We evaluated the quality of life of the elderly diabetic patients using a demographic information questionnaire and full items on Short Form (36) Health Survey (SF-36).

Serum calcium levels are not associated with coronary heart disease.

Background: Numerous studies have reported that low calcium intake is related to a higher prevalence of cardiovascular disease. However, the relationship between serum calcium and coronary heart disease is unclear. The purpose of this study was to compare serum calcium levels in patients with coronary heart disease and those in healthy individuals.

The relationship between serum calcium level, blood lipids, and blood pressure in hypertensive and normotensive subjects who come from a normal university in east of China.

Previous studies revealed that low calcium intake is related to high prevalence of cardiovascular diseases such as hypertension. However, the relationship between serum calcium and blood pressure was unclear. The prevalence of hypertension is high in China.

[Protective effect of paeonol on neurotoxicity induced by Abeta1-42 and underlying mechanisms].

Objective: To investigate the protective effect of paeonol on amyloid beta1-42 (Abeta1-42)-induced neurotoxicity and its mechanism.

Method: Hippocampal neurons of well-grown newborn SD rats and differentiated SH-SY5Y cell lines were cultured with various concentrations of paeonol (1, 5, 10 micromol x L(-1), respectively) for 6 hours and then incubated with Abeta1-42 oligomer (30 micromol x L(-1)) for 24 hours and 48 hours, respectively. The neuron apoptosis was observed by Heochst33258.

Enhancement of mercury capture by the simultaneous addition of hydrogen bromide (HBr) and fly ashes in a slipstream facility.

Low halogen content in tested Powder River Basin (PRB) coals and low loss of ignition content (LOI) in PRB-derived fly ash were likely responsible for higher elemental mercury content (averaging about 75%) in the flue gas and also lower mercury capture efficiency by electrostatic precipitator (ESP) and wet-FGD. To develop a cost-effective approach to mercury capture in a full-scale coal-fired utility boiler burning PRB coal, experiments were conducted adding hydrogen bromide (HBr) or simultaneously adding HBr and selected fly ashes in a slipstream reactor (0.152 x 0.

Impacts of halogen additions on mercury oxidation, in a slipstream selective catalyst reduction (SCR), reactor when burning sub-bituminous coal.

This paper presents a comparison of impacts of halogen species on the elemental mercury (Hg(0)) oxidation in a real coal-derived flue gas atmosphere. It is reported there is a higher percentage of Hg(0) in the flue gas when burning sub-bituminous coal (herein Powder River Basin (PRB) coal) and lignite, even with the use of selective catalytic reduction (SCR). The higher Hg(0)concentration in the flue gas makes it difficult to use the wet-FGD process for the mercury emission control in coal-fired utility boilers.
