Authors: Lin Ying-Ying , Guo Shi-Jie , Quan Hui , Zhao Yan-Xin , Huang Dong-Ya 
Published: April 2020

Background:
Hemiplegia is a common symptom after acute cerebral infarction.

Objective:
This study aimed to explore the influence factors of gait performance and investigate
whether donepezil could improve gait performance in patients with an acute cerebral infarction.

Methods:
A total of 107 patients who experienced unilateral paresis after an acute cerebral infarction
incident were enrolled in this prospectively observational study. Participants underwent a 3-
month assessment. At the study's conclusion, patients were divided into 2 groups-those who received
donepezil daily (observation Group) and those who did not (Control Group).

Results:
There was a significant difference (t=3.269, P=0.001) of Wisconsin Gait Scale (WGS)
score between single site infarction (27.11±6.65) and multiple sites infarction (31.54±6.42). For
gender, smoking, drinking, hypertension, hyperlipidemia and diabetes, there was no difference in
WGS scores between subgroups (P>0.05), respectively. The patient's admission National Institute
of Health Stroke Scale(NIHSS) score had a strongly positive correlation with WGS score (r=0.850,
P<0.001). Besides, age (r=0.218, P=0.024), glycosylated hemoglobin (r=0.274, P=0.004), MMSE
(r=-0.261, P=0.007) and Montreal Cognitive Assessment (MoCA) (r=-0.272, P=0.005) had a weak
correlation with WGS scores. Multivariate analysis showed age (95% CI: 0.042~0.188, P=0.002),
admission NIHSS score (95% CI: 2.405~3.137, P<0.001) and multiple sites infarction (95% CI:
0.044~2.983, P=0.044) were independent risk factors of WGS scores. WGS scores of both observation
and control groups gradually decreased after admission (P<0.001). At 3 months after admission,
WGS score of the observation group was significantly lower than the control group
(t=2.468, P=0.015). There were no significant differences between observation and control group
at admission and 1 month after admission (P>0.05) and WGS scores of both single site and multiple
sites infarction gradually decreased at one month and three months after admission (P<0.001),
while there was no significant difference between two groups (P>0.05).

Conclusion:
Admission NIHSS score, age and multiple sites infarction were independent risk factors
of WGS score. Donepezil could improve gait performance in patients with acute cerebral infarction.

Published: April 2020

:
Hydrogenation of CO2 to energy-rich products over heterogeneous metal catalysts has
gained much attention due to their commercial applications. Specifically, the first-row transition metal
catalysts are very rarely reported and discussed for the production of formic acid from the hydrogenation
of CO2. Herein, hydrotalcite supported copper metal has shown activity and efficiency to produce
formic acid from the hydrogenation of CO2, without adding any additional base or promoter and was
effectively recycled 4 times after separating by simple filtration without compromising the formic acid
yield. Hydrotalcite supported copper-based catalyst (Cu-HT) was synthesized through the coprecipitation
method and used as a heterogeneous catalyst for the hydrogenation of CO2. The precise
copper metal content determined by ICP in Cu-HT is 0.00944 mmol. The catalyst afforded maximum
TOF, 124 h-1 under the employed reaction conditions: 100 mg catalyst, 60 °C, 60 bar total pressure of
CO2/H2 (1:1, p/p) with 60 mL of mixed methanol:water (5:1, v/v) solvent. Cu-HT catalyst was synthesised
and thoroughly characterized by FT-IR, PXRD, SEM, TEM, XPS and BET surface area. The
first-order kinetic dependence with respect to the catalyst amount, partial pressures of CO2, and of H2
was observed and a plausible reaction mechanism is suggested.

Background:
CO2 hydrogenation to energy-rich products over heterogeneous metal catalysts has
gained much attention due to their commercial applications. Specifically, the first-row transition metal
catalysts are very rarely reported and discussed for the production of formic acid from the hydrogenation
of CO2.

Objective:
he aim is to investigate the heterogeneous catalyst systems, using solid soft base hydrotalcite
supported Cu metal-based catalyst for effective and selective hydrogenation of CO2 to formic
acid.

Methods:
The Cu –HT catalyst was synthesized and characterized by FT-IR, PXRD, SEM, TEM, XPS
and BET surface area in which the precise copper content was 0.00944 mmol. The Cu-HT catalysed
hydrogenation of CO2 was carried out in the autoclave.

Results:
The Cu-HT catalyst afforded maximum TOF of 124 h-1 under the employed reaction conditions:
100 mg catalyst, 60 °C, 60 bar total pressure of CO2/H2 (1:1, p/p) with 60 mL of mixed methanol: water
(5:1, v/v) solvent, without adding any additional base or promoter and was recycled 4 times by simple
filtration without compromising the formic acid yield. Formation of formic acid was observed to depend
on the amount of the catalyst, partial pressures of CO2 and H2, total pressure, temperature and time.

Conclusion:
Cu-HT based heterogeneous catalyst was found to be efficient for selective hydrogenation of
CO2 to formic acid and was effectively recycled four times after elegantly separating by simple filtration.

Authors: Lim Su Lin , Johal Jolyn , Ong Kai Wen , Han Chad Yixian , Chan Yiong Huak , Lee Yin Mei , Loo Wai Mun 
Published: April 2020

Background
The prevalence of nonalcoholic fatty liver disease (NAFLD) reaches up to 30% in the Asian adult population, with a higher prevalence in obese patients. Weight reduction is typically recommended for patients at high risk or diagnosed with NAFLD, but is a challenge to achieve.

Objective
We aimed to evaluate the effect of a lifestyle intervention with a mobile app on weight loss in NAFLD patients.

Methods
This prospective randomized controlled trial included 108 adults with NAFLD confirmed by steatosis on ultrasound and a body mass index ≥23 kg/m2 who were recruited from a fatty liver outpatient clinic. The patients were randomly allocated to either a control group (n=53) receiving standard care, consisting of dietary and lifestyle advice by a trained nurse, or an intervention group (n=55) utilizing the Nutritionist Buddy (nBuddy) mobile app in addition to receiving dietary and lifestyle advice by a dietitian. Body weight, alanine aminotransferase (ALT), aspartate aminotransferase (AST), waist circumference, and blood pressure were measured at baseline, and then at 3 and 6 months. Intention-to-treat and per-protocol analyses were used for statistical comparisons.

Results
The intervention group had a 5-fold higher likelihood (relative risk 5.2, P=.003, 95% CI 1.8-15.4) of achieving ≥5% weight loss compared to the control group at 6 months. The intervention group also showed greater reductions in weight (mean 3.2, SD 4.1 kg vs mean 0.5, SD 2.9 kg; P<.001), waist circumference (mean 2.9, SD 5.0 cm vs mean –0.7, SD 4.4 cm; P<.001), systolic blood pressure (mean 12.4, SD 14.8 mmHg vs mean 2.4, SD 12.4 mmHg; P=.003), diastolic blood pressure (mean 6.8, SD 8.9 mmHg vs mean –0.9, SD 10.0 mmHg; P=.001), ALT (mean 33.5, SD 40.4 IU/L vs mean 11.5, SD 35.2 IU/L; P=.004), and AST (mean 17.4, SD 27.5 U/L vs mean 7.4, SD 17.6 IU/L, P=.03) at 6 months.

Conclusions
Lifestyle intervention enabled by a mobile app can be effective in improving anthropometric indices and liver enzymes in patients with NAFLD. This treatment modality has the potential to be extended to a larger population scale.

Authors: Saltykov Ivan P. 
Published: April 2020

Introduction. The theoretical and practical approach on the base of the discrete parameter's method to the acoustic insulation of the thin partitions by Candidate of Science, Prof. Zakharov A.V. is given in this issue. The method allowed to develop a logically conclusive and consistent physical airborne sound insulation model for one-layered massive and light partitions either. This issue concentrates on providing of the engineer calculation technique of the sound insula-tion for the thin partitions and, also, on comparison of the technique's results with the computations by the current normative documents.
Materials and methods. The application of the same “Mass Action Law's” formula both for the normal and the oblique noise wave's incidence on the sound isolating plate, regardless the sound waves angles, is mathematically and physically approved. The essence of the concentrated parameters, such as concentrated and reduced material's mass, is revealed. The equations of momentum conservation law and kinetic energy conservation are used to obtain the coefficient of the oscillation velocity transmission. The formulas for airborne sound insulation at the diapasons before and after the sound wave's coincidence frequency are written.
Results. The damping air property's influence on the thin partition's sound insulation is considered, and it's formulas are represented. The formulas for taking into account the reduction of sound insulation at the resonances in sound protective slab or in a partition are also given. The general equation for the thin partition's sound insulation by the method of localized (discrete) parameters are derived. The example of detailed calculation of the sound isolation of the thin asbestos-cement partition is demonstrated. The comparison between the medial three octave deviations of the sound isolation values and the experimental results in case of the SP (Russian normative document) method and in case of the introduced author's method for the different construction materials is represented.
Conclusions. The proposedsound insulation calculation method for the thin light partitions, which is based on the concentrated parameters model, gives very close to experiments results. So, it enables to find the insulation figures across the entire standard frequency range, according to the initial physical and technical materials' and constructions' features.
