PMID: 20011054 DOI: 10.1155/2010/530265

Studies on ligand binding potential of glycyrrhizic acid, a potential agonist to PPARgamma, displayed encouraging results in amelioration of metabolic syndrome. The regulation of gene cassettes by PPARgamma affects glucose homeostasis, lipid, lipoprotein metabolism and adipogenesis. This study was performed to determine the effects of GA on total PPARgamma and LPL expression levels, lipid parameters and HOMA-IR. Oral administration of 100 mg/kg GA for 24 hours resulted in an increase in insulin sensitivity with decreases in blood glucose, serum insulin and HOMA-IR. Improvement in serum lipid parameters was also observed with a decrease in triacylglycerol, total cholesterol and LDL-cholesterol and an elevation in HDL-cholesterol. GA administration also resulted in up-regulation of total PPARgamma and LPL expression levels in the visceral and subcutaneous adipose tissues, abdominal and quadriceps femoris muscles, as well as liver and kidney, with a significant up-regulation only in the visceral adipose tissue, abdominal and quadriceps femoris muscles. Thus, oral administration of 100 mg/kg GA for 24 hours improved insulin sensitivity and lipid profiles and induced upregulation of total PPARgamma and LPL expression levels in all studied tissues.

The considerable increase in world energy consumption owing to rising global population, intercontinental transportation and industrialization has posed numerous environmental concerns. Particularly, in order to meet the required electricity supply, thermal power plants for electricity generation are widely used in many countries. However, an annually excessive quantity of waste fly ash up to 1 billion tones was globally discarded from the combustion of various carbon-containing feedstocks in thermoelectricity plants. About half of the industrially generated fly ash is dumped into landfills and hence causing soil and water contamination. Nonetheless, fly ash still contains many valuable components and possesses outstanding physicochemical properties. Utilizing waste fly ash for producing value-added products has gained significant interests. Therefore, in this work, we reviewed the current implementation of fly ash-derived materials, namely, zeolite and geopolymer as efficient adsorbents for the environmental treatment of flue gas and polluted water. Additionally, the usage of fly ash as a catalyst support for the photodegradation of organic pollutants and reforming processes for the corresponding wastewater remediation and H2 energy generation is thoroughly covered. In comparison with conventional carbon-based adsorbents, fly ash-derived geopolymer and zeolite materials reportedly exhibited greater heavy metal ions removal and reached the maximum adsorption capacity of about 150 mg g-1. As a support for biogas reforming process, fly ash could enhance the activity of Ni catalyst with 96% and 97% of CO2 and CH4 conversions, respectively.

INTRODUCTION: HIV testing uptake remains very low among men who have sex with men (MSM) in Malaysia, a subgroup still bearing a disproportionate HIV burden. Therefore, we sought to identify and measure factors associated with never-testing for HIV among Malaysian MSM to further characterize this subgroup and inform future public health interventions addressing low testing rates in the country.
METHODS: We conducted a cross-sectional online survey among Malaysian MSM (August to September 2021). Participants completed questionnaires, including socio-demographic characteristics, HIV/STI testing practices, drug- and sex-related behaviors, and knowledge and attitudes toward HIV prevention services. Out of 1,799 completed surveys, 870 were included in the analysis after eliminating duplicates and incomplete surveys. We used logistic regression to determine factors associated with never-testing for HIV.
RESULTS: Overall, one-third of the study participants (33.8%) reported having never tested for HIV. Of those who reported to have tested for HIV (n = 576), half reported that they had tested for HIV in the past 6 months (50.3%). In multivariable logistic regression, MSM with HIV sero-concordant partner (aOR = 3.44, 95% CI = 1.56-7.60), without a prior diagnosis of a sexually transmitted infection (aOR = 2.83, 95% CI = 1.46-5.49), unaware of pre-exposure prophylaxis (PrEP; aOR = 2.71, 95% CI = 1.74-4.21), unaware of someone taking PrEP (aOR = 1.64, 95% CI = 1.15-2.35), and unwilling to use PrEP (aOR = 2.48, 95% CI = 1.43-4.30) had higher odds of never been tested for HIV. In contrast, MSM who were older (aOR = 0.95, 95% CI = 0.93-0.97) and of the Malaya ethnic group (aOR = 0.59, 95% CI = 0.37-0.95) had lower odds of never testing for HIV.
CONCLUSION: Our findings shed light on the characteristics of HIV never-testers among MSM in Malaysia. The results indicate the need for innovative strategies to increase the uptake of HIV testing services among members of the MSM community.

The recent approval of long-acting injectable cabotegravir (CAB-LA) as PrEP for HIV prevention could be an attractive alternative for MSM, particularly among those who face barriers to adherence using the oral pill. This study reports on the awareness of long-acting injectable PrEP (LAI-PrEP) and factors associated with interest in LAI-PrEP use among a nationwide sample of MSM in Malaysia. An online cross-sectional survey was conducted between August and September 2021 to explore perspectives on PrEP modalities among Malaysian MSM (N = 870). Convenience sampling was used to recruit participants using ads on two platforms hornet and facebook. While only 9.1% of the study participants were aware of LAI-PrEP, the majority had heard of oral PrEP (80.9%). After giving a description of it, a large majority (86.6%) expressed interest in using it if made accessible. Those who had a prior history of HIV testing (aOR = 1.9; 95% CI = 1.2-3.2) were more likely to use LAI-PrEP. Interestingly, despite the concerns related to potential high cost (aOR = 3.4; 95% CI = 2.1-5.5) and long-term side effects (aOR = 1.9; 95% CI = 1.2-3.1), the majority of the participants were interested in using LAI-PrEP. Those who were afraid of (or disliked) syringes were less interested in using it (aOR = 0.2; 95% CI; 0.1-0.4). In the recent context that LAI-PrEP was shown to be safe and effective at preventing HIV, our results indicate its potential relevance as an additional PrEP option that could accelerate the uptake and scale-up of PrEP. However, it is crucial to conduct future research urgently to improve the understanding of strategies that could enhance the accessibility, acceptability, and affordability of LAI-PrEP for MSM in low- and middle-income countries, including Malaysia.
Fulltext Contrasting Computational Models of Mate Preference Integration Across 45 Countries

Humans express a wide array of ideal mate preferences. Around the world, people desire romantic partners who are intelligent, healthy, kind, physically attractive, wealthy, and more. In order for these ideal preferences to guide the choice of actual romantic partners, human mating psychology must possess a means to integrate information across these many preference dimensions into summaries of the overall mate value of their potential mates. Here we explore the computational design of this mate preference integration process using a large sample of n = 14,487 people from 45 countries around the world. We combine this large cross-cultural sample with agent-based models to compare eight hypothesized models of human mating markets. Across cultures, people higher in mate value appear to experience greater power of choice on the mating market in that they set higher ideal standards, better fulfill their preferences in choice, and pair with higher mate value partners. Furthermore, we find that this cross-culturally universal pattern of mate choice is most consistent with a Euclidean model of mate preference integration.

The Triangular Theory of Love (measured with Sternberg's Triangular Love Scale - STLS) is a prominent theoretical concept in empirical research on love. To expand the culturally homogeneous body of previous psychometric research regarding the STLS, we conducted a large-scale cross-cultural study with the use of this scale. In total, we examined more than 11,000 respondents, but as a result of applied exclusion criteria, the final analyses were based on a sample of 7332 participants from 25 countries (from all inhabited continents). We tested configural invariance, metric invariance, and scalar invariance, all of which confirmed the cultural universality of the theoretical construct of love analyzed in our study. We also observed that levels of love components differ depending on relationship duration, following the dynamics suggested in the Triangular Theory of Love. Supplementary files with all our data, including results on love intensity across different countries along with STLS versions adapted in a few dozen languages, will further enable more extensive research on the Triangular Theory of Love.
