Association between pm2.5 concentrations and hospitalization cases for schizophrenia and mood disorders in Ho Chi Minh city, Vietnam from 2019 to 2020
Authors:   , Thuong Do 
Published: April 2023

The evidence for adverse effects of ambient particulate matter pollution on mental and behavioral disorders (MBDs) is limited. Until now, few epidemiological studies have focused on this field, especially in developing countries. With the changes in concentrations and sources of air pollution over the past decade in Vietnam lead to high levels of air pollutants, especially particulate matters including PM2.5. Therefore, it is worthwhile to investigate the acute effects of outdoor air pollution on MBDs. However, no Vietnamese study has looked into the short-term effect of PM2.5 on hospitalization for MBDs.

To examine the association between PM2.5 and the cases for total MBDs, Schizophrenia and Mood disorder from June 2019 to December 2020 at Ho Chi Minh City Mental health hospital. A quasi-Poisson time series regression model was used to determine the association between PM2.5 exposure and daily hospital admission for all-cause mental disorders and two specific disorders including Schizophrenia and Mood disorder. A natural cubic regression smooth function was adopted to filter out long term trends and seasonality and stratified analyses were also performed by age, gender and season. Besides, to estimate the delayed effect, we examined the association in distributed lag models when lag terms were modelled one at a time (from lag0 to lag7). We select the most optimal model based on the Q-AIC criterion (Akaike Information Criterion).

In total, 3,513 hospital admissions for MBDs were collected from HCMC Mental health hospital in 2019-2020. The number of hospital admissions of Schizophrenia was nearly four times of Mood disorder (1,724 vs 447 admissions, respectively). Data from monitoring stations suggested that the daily concentration of PM2.5 ranged from 8.7 to 66.0 μg/m3 with a mean of 25.6 μg/m3. Results revealed that each 10 μg/m3 increase in PM2.5 at lag 7 for MBDs and Schizophrenia corresponded to an increase of 1.25 (95%CI: 1.03 – 1.52), 1.45 (95%CI: 1.12-1.89) in daily hospital admission among the elderly, respectively.

Our study demonstrated that the elderly in HCMC have an increased risk of MBDs admissions due to the high level of PM2.5 concentration in the city's ambient air. These findings have provided evidence for building public health policies to prevent and minimize the adverse health effects of air pollution on the elderly.

Authors:   , Phairoh Krittapat 
Published: April 2023

The genus Derris belonging to Fabaceae family are distributed along the equatorial zone in Africa and Asia. In Thailand, 16 species of Derris species can be found throughout the country. Derris elliptica (Hanglai-Dang), is well-known among fishermen and gardeners as fish poison and insecticide, especially the stem and root which contain isoflavonoid compound named rotenone. This study established the pharmacognostic specification of Derris elliptica dried stem crude drug and developed the quantitative analysis of rotenone content in D. elliptica stem using TLC-densitometry and image analysis. The physico-chemical parameters of D. elliptica stem included total ash, acid-insoluble ash, loss on drying and water contents that should not be more than 7, 1, 5 and 8 g/ 100g crude drug, respectively. The ethanol and water extractive values should not be less than 4 and 11 g/ 100 g crude drug, respectively. Microscopic characteristics (transverse section and powder) of D.elliptica stem were illustrated by hand drawing. Rotenone contents obtained from both quantitative TLC were 0.2870 ± 0.1242 and 0.2844 ±0.1209 g/100 g crude drug, respectively which was not statistically significantly different (P > 0.05). In vitro biological activities of the stem ethanolic extract and rotenone revealed the antioxidant, α-glucosidase inhibitory properties and brine shrimp toxicity. MTT assay revealed that the ethanolic extract and rotenone were marginal cytotoxic (LC50 > 20 µg/ml) against the cancer cells (MAD-231, HepG2, HT-29, CaCo-2). Microscopic leaf characteristics including leaf constant numbers of 8 Derris ( D. amonea, D. malaccensis, D. elliptica, D. reticulate, D. trifoliate, D. indica, D. solorioides ) were shown that stomatal number, stomata index, palisade ratio, epidermal cell area, trichome number could be used as the identification key for selected 8 species. DNA fingerprinting using ISSR 11, 12, 14, 17 and 35 as primers produced a total of distinct and reproducible 256 bands. The genetic relationship among selected Derris species presented the similarity index between 0.11 to 0.43. The information from this research can be applied for identification of D. elliptica stems in Thailand as well as providing the information of pharmacogenetic specification, including rotenone content in and in vitro biological properties of D. elliptica stem.

Morus alba Linn., belonging to Moraceae family, is commonly used as an herb. M. alba leaves are widely used in traditional Chinese medicine and Thai traditional medicine. It used to treat colds caused by wind-heat, sore throat, cough, eye inflammation, etc. This study aimed to investigate the pharmacognostic specifications and analyze the content of chlorogenic acid in M. alba leaves. M. alba leaves were collected from 15 different sources throughout Thailand. The fresh mature leaves were used for macroscopic and microscopic evaluations. The macroscopic details were illustrated as drawings. The microscopic evaluation showed the details of the leaf constant number and the cross-section of the midrib. M. alba leaves were cleaned and dried for analysis of pharmacologic specification. The parameters included water content (7.97 ± 0.35%), water-extractive value (16.14 ± 0.50%), ethanol-extractive value (8.61 ± 0.39%), loss on drying (4.55 ± 0.21%), total ash (14.38 ± 0.25%) and acid-insoluble ash (6.21 ± 0.37%). The preliminary phytochemical examination of M. alba leaves showed the detection of phenolic compounds, flavonoids, steroids and triterpenes. The dried M. alba leaves were extracted with 95% ethanol by using Soxhlet apparatus. The quantitative analysis of chlorogenic acid content was analyzed by using RP-HPLC. A C18 column was used as a stationary phase and methanol: 0.2% phosphoric acid (45%: 55%) was used as a mobile phase. The content of chlorogenic acid of M. alba leaves was found to be 0.4159 ± 0.20 g/100g by dry weight.

Authors:   , Srisiri Sirawich 
Published: April 2023

Microplastic (MP) problems have been threatened aquatic environment worldwide for decades. This study demonstrated current MP contamination characteristics in marine food fishes from the upper Gulf of Thailand. MPs were found in gastrointestinal tracts of 46.86% of fish samples, which were 1.556±0.47 pieces per fish or 0.035±0.014 pieces per gram of fish bodyweight. No plastics were detected from muscle, liver, kidney or gonad of the fishes. There was a significant relationship between MP contamination and fish species or the fish grouping. Benthic fish had a higher contamination rate than pelagic fish. Fiber-type and blue color were the most abundant MPs characteristic observed. The most common polymer was polyester, followed by polyethylene. Polyester was a dominant polymer among benthic fishes while polyethylene dominant in pelagic fishes. The contamination of MPs was not related to histopathological lesions in natural marine fishes. The expected MPs exposure of Thai marine fish consumers were 0.06 pieces per person per day for general marine fish and 0.095 pieces per person per day for Short Mackerel. The expected exposure risk from consuming fish muscle and risk from fishmeal consuming animal were still relatively low. Continuing surveillance and exposure assessment are crucial in determining MP risks to human health in near future.
Development of nanostructured lipid carrier clove oil as anesthetic agent in white shrimp (Litopenaeus vannamei)
Authors:   , Kaewmalun Somrudee 
Published: April 2023

Clove oil is an essential oil extracted from the dried buds and leaves of the clove plant (Syzygium aromaticum). Clove oil contains eugenol as the main active ingredient. Clove oil used as an anesthesia functions as calming effect, loss of equilibrium, non-reactivity and consciousness in lead to reduce activity, physiological stress, mortality rate, and preventing cannibalism method during handling and transportation. However, the component of clove oil is insoluble in water and must be dissolved in ethanol. So, clove oil ethanolic solution leading to toxic and irritation in animal and user. In this study, to avoid this side effect, the anesthetic preparation of clove oil without ethanol is an attempt to be developed. We have prepared a new generation of clove oil in the form of NLCs to enhance water miscibility, high efficacy, better physical stability, and low toxicity compared with STD clove oil. The clove oil NLCs obtained were characterized in terms of physicochemical, efficacy, toxicity and biodistribution of clove oil NLCs. The results showed that clove oil NLCs had particle size of 175.07 ± 0.72 nm, zeta potential of -48.37 ± .38, PDI of 0.115 ± 0.230. Clove oil NLCs have spherical particle shape, %encapsulation efficiency of clove oil NPs was 88.55% and demonstrated sustained release of active ingredients. The anesthetic effects of clove oil were studied in white shrimp (average 3 g). Clove oil concentration at 10, 20, 30, 40, 50, 60, 70, 100, 120, 140, 160, 180 and 200 ppm of clove oil NLCs and STD clove oil were used in study. The results showed no effect of clove oil to white shrimp at 10 ppm of both groups. After exposure to clove oil NLCs at 30 ppm, showed the shrimp can be started to stage 2 (Complete loss of equilibrium) while shrimp of STD clove oil group be started to stage 2 within 5 minutes at concentrations of 50 ppm. The optimum concentration of anesthetic was 30 ppm in shrimp which induced shrimp to stage 2 within 5 minutes after exposure to Clove oil NLCs. The toxicity of clove oil to different concentration of clove oil was studied and median lethal concentration (LC50) at 48 h were report in toxicity study. The result show that the STD clove oil concentration of 140 ppm resulted in median lethal concentration (LC50 48h), whereas the concentration of 140 ppm of clove NLCs led to a 0% mortality over a 48-h period. And the result of biodistribution study of clove, it was found that shrimp in clove oil NLCs group was able to excrete clove oil from the body within 30 minutes but shrimp in STD clove oil group was still detected clove oil in shrimp. In conclusion, the clove oil NLCs has been successfully developed with enhanced water miscibility, increased high anesthetic efficacy with a sustained release, reduction of clove oil toxicity and clove oil NLCs do not accumulate on the shrimp body.
The Case for Expanding the Anticanon of Constitutional Law
Authors: Somin Ilya 
Published: April 2023

The “anticanon” of constitutional law is an underappreciated constraint on judicial discretion. Some past decisions are so reviled that no judge can issue analogous rulings today, without suffering massive damage to their reputation. This Essay argues for expanding the anti-canon and proposes three worthy new candidates: The Chinese Exclusion Case, Euclid v. Ambler Realty, and Berman v. Parker. The three rulings all share in spades the main characteristics of other anti-canonical decisions: (1) terrible legal reasoning, (2) enormously harmful real-world effects, and (3) facilitating racial and ethnic discrimination and oppression.	Part I outlines the nature of the anticanon and how cases can “qualify” for it. Part II makes the case for adding new cases to the anticanon. Finally, Part III explains why The Chinese Exclusion Case, Euclid, and Berman would be worthy additions to the Supreme Court’s Hall of Shame.
