Abstract
This study aims to determine the characteristics of oil palm boiler ash (OPBA) after processing with ball mill and coprecipitation methods. The method used is OPBA from a palm oil mill, processed using a ball mill for 1 hour at a speed of 250 rpm. Then prepared with the coprecipitation method by dissolving it in 2M HCl solution and NaOH solution with variations (2; 2.5; 3) M. Particles were characterized by XRD, SEM, XRF, and FTIR. XRD characterization shows the size of each crystal (83,79; 72,30 and 56,31) nm, with trigonal crystal structure with the SiO2 phase. SEM shows a homogeneous mixture. EDX shows the biggest elements are Si, O and C content. XRF shows the amount of silica is 31.45%. FTIR shows absorption peaks which are the characters of molecular vibrations of the sample.
Altered pain processing and sensitisation is evident in adults with patellofemoral pain: a systematic review including meta-analysis and meta-regression
Authors: Bartholomew Clare , Lack Simon , Neal Bradley 
Published: September 2019

Abstract

Background and aims
Previous systematic reviews have reported manifestations of pain sensitisation as a feature of painful knee disorders, in particular osteoarthritis, with moderate evidence for pain sensitisation in patellofemoral pain (PFP). However, despite past studies recruiting female mostly adolescent PFP patients, it is unclear if sex or age plays a role. Investigation is required to determine if altered pain processing is a key feature of PFP and if a subgroup of patients is at an increased risk to help provide targeted management. The primary aim of this systematic review was to examine evidence investigating pain processing in PFP. Secondary aims were to evaluate the relationship between pain processing and (1) sex, (2) age and (3) symptom duration.

Methods
The protocol was prospectively registered with PROSPERO (CRD42019129851). PubMed, CINAHL, Web of Science and EMBASE were systematically searched from inception to April 2019 for studies investigating pain processing in PFP patients compared to controls using quantitative sensory testing. Each included paper was assessed for methodological quality using a modified version of Downs and Black. Means and standard deviations were extracted to calculate standardised mean differences (SMD) and 95% confidence intervals (95% CI). Where possible meta-analysis and meta-regression were performed using a random effects model.

Results
Eleven studies were identified, two medium and nine high quality. Meta-analysis indicates moderate evidence for decreased pressure pain thresholds (SMD −0.68, 95% CI −0.93 to −0.43), increased tactile detection thresholds (SMD 1.35, 95% CI 0.49–2.22) and increased warmth detection thresholds (SMD 0.61, 95% CI 0.30–0.92) in PFP patients compared to controls. Secondary analysis indicates moderate evidence for decreased pressure pain thresholds in female compared to male patients (SMD −0.75, 95% CI −1.34 to −0.16). Meta-regression indicates a moderate correlation between decreasing local and distal pressure pain thresholds and decreasing patient age (local R2 = 0.556, p = 0.0211; distal R2 = 0.491, p = 0.0354) but no correlation with symptom duration (p > 0.05).

Conclusions
Evidence from this systematic review with meta-analysis and meta-regression appears to suggest the presence of altered pain processing and sensitisation in patients with PFP with increased sensitivity indicated in female patients and younger patients.

Implications
With evidence of altered pain processing and sensitisation in PFP, it may be beneficial for clinicians to consider management approaches that aim specifically at adressing neuropathic pain, for example neuroscience education, to improve patients outcomes. With female patients and younger patients indicated as experiencing greater degree of sensitivity, this may be a good demographic to start screening for sensitisation, in order to better identify and treat those most affected.

Abstract
A dihydropyrimidine (DHPM) derivative was synthesized, characterized by X-ray diffraction and searched in silico for its inhibitory activities against AccD5 enzyme, the CT domain of a Mycobacterium tuberculosis ACCase. Its molecular structure was compared to another DHPM derivative (DHPM II). The results have shown that the (±)2,6-methano-4-thioxo-3,4,5,6-tetrahydro-2H-[1,3,5] benzoxadiazocines (DHPM I) and (±)2,6-methano-4-oxo-3,4,5,6-tetrahydro-2H-[1,3,5] benzoxadiazocines (DHPM II) belong to the monoclinic and triclinic systems, respectively, and their crystal structures are stabilized by N–H⋯O, O–H⋯O and N–H⋯S interactions. The DHPM derivatives established hydrogen bond interactions with the oxyanion-stabilizing residues (Gly-434/Ala-435) beyond the Thr-217, Phe-394 and Ile-216 in the biotin pocket. The predicted MoB of the DHPM derivatives (21R, 24S, 22R) configuration showed that its phenyl moiety was positioned on the interface between the biotin and propionyl-CoA pockets, suggesting a possible blockade of both subsites. Additionally, the hydrogen bonds involving the O-bridged phenyl ring of the DHPM derivatives (21S, 24R, 22S) configuration with Gly434 in the oxyanion-stabilizing region placed its phenyl moiety in the bottom of the biotin pocket establishing hydrophobic interactions with Leu164, Tyr167, Val459 and Ala155. These results indicate the DHPM derivatives as potential AccD5 inhibitors and promising starting points for future optimizations. Although the overlap of DHPM I and DHPM II did not present significant differences, the exchange of a sulfur atom for an oxygen atom increased the predicted biological potential.

Abstract
Martínez-Cava, A, Hernández-Belmonte, A, Courel-Ibáñez, J, Morán-Navarro, R, González-Badillo, JJ, and Pallarés, JG. Bench press at full range of motion produces greater neuromuscular adaptations than partial executions after prolonged resistance training. J Strength Cond Res 36(1): 10–15, 2022—Training at a particular range of motion (ROM) produces specific neuromuscular adaptations. However, the effects of full and partial ROM in one of the most common upper-limb exercises such as the bench press (BP) remain controversial. In this study, 50 recreationally to highly resistance trained men were randomly assigned to 1 of 4 training groups: full bench press (BPFULL), two-thirds bench press (BP2/3), and one-third bench press (BP1/3) and control (training cessation). Experimental groups completed a 10-week velocity-based resistance training program using the same relative load (linear periodization, 60–80% 1 repetition maximum [1RM]), only differing in the ROM trained. Individual ROM for each BP variation was determined in the familiarization and subsequently replicated in every lift during training and testing sessions. Neuromuscular adaptations were evaluated by 1RM strength and mean propulsive velocity (MPV). The BPFULL group obtained the best results for the 3 BP variations (effect size [ES] = 0.52–1.96); in turn, partial BP produced smaller improvements as the ROM decreased (BP2/3: ES = 0.29–0.78; BP1/3: ES = −0.01 to 0.66). After 10-week of training cessation, the control group declined in all neuromuscular parameters (ES = 0.86–0.92) except in MPV against low loads. Based on these findings, the BPFULL stands as the most effective exercise to maximize neuromuscular improvements in recreational and well-trained athletes compared with partial ROM variations.

Published: September 2019

Summary
A 26-year-old woman presented with persistent headache and tiredness. Biological investigations disclosed a moderate inflammatory syndrome, low PTH-hypercalcemia and complete anterior hypopituitarism. A magnetic resonance imaging (MRI) of the pituitary gland was performed and revealed a symmetric enlargement with a heterogeneous signal. Ophthalmological examination showed an asymptomatic bilateral anterior and posterior uveitis, and a diagnosis of pituitary sarcoidosis was suspected. As the localization of lymphadenopathies on the fused whole-body FDG-PET/computerized tomography (CT) was not evoking a sarcoidosis in first instance, an excisional biopsy of a left supraclavicular adenopathy was performed showing classic nodular sclerosis Hodgkin’s lymphoma (HL). A diagnostic transsphenoidal biopsy of the pituitary gland was proposed for accurate staging of the HL and surprisingly revealed typical granulomatous inflammation secondary to sarcoidosis, leading to the diagnosis of a sarcoidosis–lymphoma syndrome. The co-existence of these diseases constitutes a diagnostic challenge and we emphasize the necessity of exact staging of disease in order to prescribe adequate treatment.

Learning points:

The possibility of a sarcoidosis–lymphoma syndrome, although rare, should be kept in mind during evaluation for lymphadenopathies.

In the case of such association, lymphoma usually occurs after sarcoidosis. However, sarcoidosis and lymphoma can be detected simultaneously and development of sarcoidosis in a patient with previous lymphoma has also been reported.

An accurate diagnosis of the disease and the respective organ involvements, including biopsy, is necessary in order to prescribe adequate treatment.

Published: September 2019

AbstractThe small ovary (sov) locus was identified in a female sterile screen, yet its molecular identity and function remained a mystery for decades. In the present work, Benner et al. molecularly map...Heterochromatin-mediated repression is essential for controlling the expression of transposons and for coordinated cell type-specific gene regulation. The small ovary (sov) locus was identified in a screen for female-sterile mutations in Drosophila melanogaster, and mutants show dramatic ovarian morphogenesis defects. We show that the null sov phenotype is lethal and map the locus to the uncharacterized gene CG14438, which encodes a nuclear zinc-finger protein that colocalizes with the essential Heterochromatin Protein 1 (HP1a). We demonstrate Sov functions to repress inappropriate gene expression in the ovary, silence transposons, and suppress position-effect variegation in the eye, suggesting a central role in heterochromatin stabilization.

Published: September 2019

Aim of study: In this study, the amount of industrial wood production of the
regional directorates of forestry in Turkey was examined deeply and the
similarities between the regional directorates in industrial wood production
were investigated by cluster and discriminant analysis.

Area of study: The study area is regional directorates of forestry in Turkey.

Material and Method: Seven different variables were used to construct similar clusters. The
arithmetic mean of these seven variables was taken for 4 years (2013-2016). Cluster and discriminant analysis were used
as method.

Main results: According to the clustering analysis results, it was determined that
regional directorates of forestry could be divided into maximum 6 and minimum 2
groups. As a result of the discriminant analysis conducted to determine the
highest success of the groupings, it was determined that the regional
directorates of forestry distinguished in 100% success in 6 groups. Also, it
was found that a Kastamonu regional directorate of forestry, which has the
highest value in industrial wood production, has formed a group alone.

Highlights: For the production of industrial wood, the regional directorates of
forestry can put more emphasis on the use of forest areas. Thus, we can avoid
the dependence on foreign sources.

Authors: Xu Guixing , Xu Ping , Zheng Donghua , Wei Wanjia 
Published: September 2019

Background: The present study aimed to assess the effect of hormone package therapy on hemodynamic stability in brain dead organ donors.Methods: In this study, patients were divided into two groups: one administered hormone package therapy, defined as simultaneous treatment with vasopressin, thyroxine and corticosteroids; and the other administered conventional therapy. Clinical findings and hemodynamic parameters were compared to analyze the effect of hormone package therapy on hemodynamic stability. Associations between hormone package therapy and hemodynamic variables were assessed by univariate and multivariate logistic regression analyses.Results: A total of 109 patients were included in the study. Based on time of enrollment, 54 and 55 patients received conventional and hormone package therapy, respectively, with 32 (59.3%) and 45 (81.8%), respectively, achieving hemodynamic stability. High-doses of a single vasoactive agent in the hormone package group better maintained hemodynamic stability and norepinephrine use compared to conventional treatment. Univariate and multivariate analyses showed that an abnormal suprasellar cistern, midline shift, low free T3, axillary temperature >36.5°C and central diabetes insipidus were associated with the effects of hormone package therapy.Conclusions: Hormone package therapy can help maintain hemodynamic stability in brain dead donors and reduce the use of vasoactive agents, thereby improving the quality of donated organs and the success rates of organ donations.

Authors: Chingale Ashwini , Katti S. M. 
Published: September 2019

Background: The elderly population is the fastest growing age group in the world. This demographic transition has important changes in quality of life in this population, given that longevity may be accompanied by non- communicable diseases, functional reduction, increased dependence, and social isolation, which can bring weight gain in the elderly. Among the elderly there is a loss of the lean body mass and increased body-fat percentage. It is a major risk factor for non-communicable diseases and mortality. The objectives of the present study were to estimate the prevalence of obesity among urban elderly using different measurement methods.Methods: It was cross-sectional study conducted between 1st January to 31st December 2013 in 700 individuals aged 60 years and above. The study participants, permanent residents of Ashok Nagar Urban field practice area, were selected using a simple random technique. Obesity was assessed by using WHO Asia-Pacific Guidelines for body mass index (BMI) and WHO waist circumference (WC) guidelines. Data was analyzed by using percentages and kappa statistics.Results: Prevalence of obesity according to BMI criteria was 38.1% and 43.0% among men and women respectively. Measurement of WC showed that 17.4% of men and 46.8% of women suffered from central obesity. There was slight agreement between obesity criteria and central obesity. Conclusions: The study highlights the problem of obesity in urban elderly. The prevalence of obesity in elderly was slightly higher, with predominance in women. An ageing population together with social, economic and lifestyle changes have led to dramatic increase in obesity.

dyes nearly 4-10 min. and green synthesized antioxidant platinum nanoparticles
were effectively degrading the dyes nearly 15-24 min. of exposure time.
STAVOVI VASPITAČA I RODITELJA PREMA UČENJU O INTEGRALNOM ODRŽIVOM RAZVOJU U PREDŠKOLSKOM OBRAZOVANJU
Authors: Radović Svetlana , Marinković Lada 
Published: September 2019

U radu su prikazani rezultati anketnog istraživanja stavova vaspitača i roditelja prema učenju o integralnom održivom razvoju u predškolskom obrazovanju. Integralni održivi razvoj je sveobuhvatan pojam koji podrazumeva ostvarenje ekološke, ekonomske, socijalne i kulturne održivosti. S obzirom da održivi razvoj pretpostavlja proaktivan odnos prema okruženju i da je rano obrazovanje ključno u razvijanju ovog odnosa, cilj istraživanja je bio da se sagleda odnos vaspitača kao prve karike u sistemu formalnog obrazovanja i roditelja kao direktnih modela za oblikovanje budućih obrazaca ponašanja dece, prema učenju o integralnom održivom razvoju na predškolskom uzrastu. Analiza je zasnovana na zainteresovanosti vaspitača i roditelja za pitanja održivog razvoja, njihovom poznavanju konstitutivnih elemenata integralnog održivog razvoja, izboru konkretnih tema kao prikladnih za učenje na predškolskom uzrastu, odnosu prema uvođenju učenja o integralnom održivom razvoju u predškolski program i percepciji aktera ovog procesa. Rezultati pokazuju da su vaspitači i roditelji zainteresovani za pitanja održivog razvoja, ali da ga ne poimaju kao integralnog. U njihovom shvatanju održivog razvoja dominiraju ekološka i delimično ekonomska i kulturna dimenzija. Procena potrebe uvođenja pojedinačnih tema iz integralnog održivog razvoja korespondira sa njihovim poimanjem održivog razvoja. Pozitivan rezultat ovog istraživanja jeste generalno pozitivan stav kako vaspitača tako i roditelja prema uvođenju učenja o integralnom održivom razvoju u predškolski program kao i uvid u značaj partnerstva svih relevantnih aktera za uspeh obrazovnog procesa i ostvarenja održivog društva.
L1 Literacy Practices’ Impact on L2 Text Organization
Authors: Sayidina Aisha 
Published: September 2019

Situated within the Intercultural Rhetoric (IR) framework, this study uses text linguistic analysis of Arab students’ English academic papers to investigate the transfer of the Arabic language instruction practices into ESL written texts. The analysis involves a comparison of surface linguistic features (syntactic relations and cohesive devices) in a corpus of Arab students and English-speaking students’ papers. Furthermore, the Arabic and English-speaking students completed surveys about the skills emphasized in their L1 classrooms. It is believed that the methods of writing instruction in Arabic, which are influenced by diglossia, are transferred into ESL written texts. The results show that the Arabic speaking and English-speaking students’ texts exhibit differences at the rhetorical level. The characteristics of the ESL texts are similar to Arabic native texts which suggest a transfer of L1 learned writing methods into L2 texts. The findings from the linguistic analysis and the data obtained from the surveys are discussed with reference to Arabic teaching methodology, diglossia, orality, and learning experience transfer from Arabic into English.

The aim of this work was to evaluate the growth of two clones of Eucalyptus saligna on salt-stress mediated by NaCl in hydroponics. Micropropagated plants of the clones p0 and p1 were acclimatizated and cultivated in hydroponics at 0 and 300 mM NaCl levels. The total length, volume, number, fresh mass and dry mass of the roots, the height, fresh and dry mass of the aerial part and the fresh and dry mass of the complete plant were evaluated to the 14 days of hydroponic culture with NaCl. There were significant differences among the clones. The clone p0 was superior to the clone p1 in relation to volume of the roots, root number, root fresh mass and total fresh mass of the root. Regards the effect of the salinity on the plants, significant reduction was observed in the height of the aerial part, fresh mass of the aerial part and the total fresh mass. Even so, the interaction between the clones and the concentrations of NaCl was significant for the total fresh mass. In the period of 14 days of hydroponic culture on 300 mM NaCl was possible to discriminate these two clones in relation to the tolerance and susceptibility to the salt stress. The clone p0 presented higher growth and larger tolerance to the salinity than clone p1.
